FIELD OF THE INVENTION

This application relates to mechanical systems for fixing and coupling and, in particular, to a bracket assembly and a storage rack system.

DESCRIPTION OF THE PRIOR ART

Storage racks are commonly used in our daily life usually for storage of clothes, daily necessities and the like in household applications and goods and products in commercial scenarios. Storage racks adapted to be mounted to a vertical surface are popular among and widely used by supermarkets and shopping malls because of less space occupied. Such a storage rack is often formed by mounting several brackets to a vertical wall or panel surface and then horizontally placing shelves on the brackets. In another common form of such storage racks, brackets are fastened to horizontal beams or upright columns fixedly mounted to a wall or panel surface, and shelves are in turn mounted to the brackets.

In both forms, shelves are secured to brackets that are fixed to upright or horizontal supports. Generally, the brackets are adapted to the shelves, i.e., the shelves require the brackets to be structured accordingly. For example, the shelves may be mesh shelves, and in this case, the structure of the brackets would be suitable for replacement of such shelves, but not of, for example, wood shelves, cabinets or drawers. In other words, each type of bracket in conventional storage rack systems can be suitably used with only a single type of shelf, and different types of shelves require the use of different types of brackets.

In addition, conventional brackets are usually triangular structures, and placement of certain shelves thereon requires passing associated fasteners through both the bracket and shelf. The triangular shape of such brackets means a varying distance between the top side, on which a bracket is to be placed, and the opposite bottom side across the length. Therefore, the use of fasteners of various lengths is required. This not only raises the manufacturing cost, but also leads to a tedious assembly process. Further, conventional brackets cannot be stably assembled with upright columns, and wobbling tends to occur during use.

Therefore, those skilled in the art are dedicated towards developing a bracket assembly, which has a wider scope of application and can be suitably used with different types of shelves, dispensing with the need for replacement or retrofit of brackets when a different type of shelf is to be used. Moreover, it allows fasteners of the same size to be used and can be used to assemble a storage rack with increased stability.

Compared with the prior art, the storage rack system of the present application has the benefits as follows:1. The differently structured mating portions enable the brackets to connect carrier components of different structures, making the bracket multi-functional and usable in a wider range of applications.2. Using such brackets in a storage rack system allows carrier components of different structures to be used in the storage rack system, such as mesh shelves, plate-like shelves, drawers and hanging hooks, in any combination. This enables the storage rack system to be used in a more flexible way and dispenses with the need for manufacturing brackets of various structures, resulting in reductions in manufacturing and assembly costs.3. Using such brackets in a storage rack system allows carrier components of different structures to be readily replaced, without requiring the replacement of brackets, resulting in higher assembly efficiency and lower replacement cost.4. The guide structure allows a carrier component to be secured to the bracket using fasteners of the same length at different locations of the bracket. This can facilitates user operation and reduce the manufacturing cost. Moreover, the guide structure can define a direction in which a fastener is inserted through the bracket and the carrier component, avoiding oblique or deviated deployment of the fastener, which is detrimental to reliably attachment of the carrier component to the bracket.5. The guide structure may be provided as a component separate from the bracket and can be extensively used on various brackets designed without considering the guide structure. This dispenses with the need for manufacturing new brackets for existing storage rack systems.6. The anti-dislodgement structure can prevent the bracket from dislodging from a slot in an upright column, enabling the bracket to be more stably coupled to the upright column and making the entire storage rack system more reliably and stable.7. A carrier component can be attached to the bracket by means of a guide rail so as to be pulled out or pushed back on the guide rail. When a user desires to pick up or place an item, he/she can pull the carrier component out relative to the guide rail to more easily pick up the item.

Below, the concept, structural details and resulting effects of the present application will be further described with reference to the accompanying drawings to provide a full understanding of the objects, features and effects of the application.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

As shown inFIGS.1,2and4, the present application provides a bracket assembly10including a bracket100which is provided in a storage rack system to support a carrier component in the storage rack system. One end of the bracket100defines a connecting portion101, through which the bracket100can be coupled to an upright column300or horizontal beam400in the storage rack system. The bracket100also defines a mating portion which can be connected to the carrier component, thereby connecting the carrier component to the bracket100and allowing goods to be then stored on the carrier component.

The carrier component may be of various structures. For example, the carrier component may be a mesh shelf210in the form of a mesh consisting of multiple interwoven struts. Alternatively, the carrier component may be a plate-like shelf230in the form of a storage plate made of wood, plastic, metal, etc. Still alternatively, the carrier component may be a drawer-like structure, which may be mated with the bracket100through a guide rail, or connected to the bracket100using fasteners. Yet still alternatively, the carrier component may be a hanging hook250. Depending on its structure, the carrier component may be connected to the bracket100in different ways. In the present application, the bracket100may define mating portions of at least two different structures, which can be connected to carrier components of different structures. In conventional storage rack systems, each bracket defines only one type of mating portion and therefore can be connected to only a defined single type of carrier component. When a different type of carrier component is to be used, replacement with another bracket with a corresponding type of mating portion is necessary. In contrast, according to the present application, as the bracket100can accommodate carrier components of at least two different structures, replacement between these differently-structured carrier components can be made simply without requiring replacement of the bracket100. It will be understood that the bracket100may define mating portions of three or more types and can be thus used in a wider range of applications, without departing from the scope of the present application. For example, in the embodiment shown inFIGS.1,2and4, the bracket100defines a first mating portion110, a second mating portion120, a third mating portion130and a fourth mating portion140. The first mating portion110can be connected to a first mating component210, such as a carrier component in the form of a mesh shelf. The second mating portion120can be connected to a second mating component230, such as a plate-like carrier component. The third mating portion130can be connected to a third mating component, which can be in turn connected to a drawer-like, cage-like or basket-like or other carrier component240defining a storage space. The fourth mating portion140can be connected to a fourth mating component250, such as a hook-like carrier component. In the illustrated embodiment, any two, three or four of the first110, second120, third130and fourth140mating portions may be included. It will be understood that, in the shown embodiment, other mating portions may also be included in addition to those illustrated.

FIGS.1to21show a first embodiment. Referring toFIG.1, the present application provides a bracket assembly10including a bracket100. The bracket100is generally triangular and defines, on its shortest side (first side102), a connecting portion101for connecting the bracket100to an upright column300or horizontal beam400. The other two sides (a second side103and a third side104) both extend from the first side102and form an acute angle therebetween. As viewed in the orientation of the figure, the second side103is an upper side, and the third side104is a lower side. It will be understood that the shape of the bracket100is not limited to being triangular, as described herein, and may be any other suitable shape, such as quadrilateral.

The bracket100includes a first bracket wall105and a second bracket wall106, which are substantially parallel to each other. It also includes a bottom bracket wall107attached to the bottom of both the first bracket wall105and the second bracket wall106. The first bracket wall105and the second bracket wall106are of the same substantially triangular shape. The first bracket wall105and the second bracket wall106are substantially of the same structure, and only one of them is exemplified below.

The connecting portion101of the bracket100includes a lug1011protruding from the first side102of the bracket100. The lug1011can be inserted into a slot301in the upright column300or horizontal beam400, thereby securely connecting the bracket100thereto. It will be understood that the connecting portion101may be alternatively provided in the form of, for example, a fastener structure which can connect the bracket100to the upright column300or horizontal beam400.

As shown inFIGS.3and4, the bracket100defines, on the second side103that is to be brought into direct contact with a carrier component, a first mating portion110for connecting a mesh shelf310. Specifically, the first mating portion110includes a number of first notches111, which are provided at the second side103in a row along its lengthwise direction. During use, transverse rod-like components211of the mesh shelf210, which are perpendicular to the bracket100, are passed through openings112of the first notches111and pushed down into the first notches111so that the mesh shelf210is prevented from sliding in the lengthwise direction of the bracket100. In some implementations, the openings111of the first notches111has a dimension in the lengthwise direction of the bracket100, which is smaller than a length of the first notches111. The openings112are defined at one end of the first notches111, and receptacles113are defined at the other end of the first notches111. After the rod-like components of the mesh shelf210enter the openings112, the mesh shelf210may be pushed so that the rod-like components are further urged into the receptacles113(seeFIG.5). Projections114above the receptacles113can block the mesh shelf210from dislodgement from the bracket100, increasing the stability of the mesh shelf210on the bracket100.

For a storage rack system employing such mesh shelves210, the stability of the mesh shelves210on the brackets100is one of the main factors that influence the load capacity of the storage rack system. Referring toFIG.3, the mesh shelf210is made up of multiple parallel transverse rod-like components211and multiple parallel longitudinal rod-like components212. Specifically, the transverse rod-like components211may be arranged under the longitudinal rod-like components212so that they cross each other to form a mesh-like structure. The bracket100defines, at an edge thereof opposite to the connecting portion101(i.e., at a leading end of the bracket100), a first stop notch108. Also, the bracket100defines a second stop notch109around the connecting portion (i.e., at a trailing end of the bracket100). Both the first stop notch108and the second stop notch109are curved, semi-closed structures. The first stop notch108is obliquely open upward toward the leading end, while the second stop notch109is obliquely open upward toward the trailing end. When a transverse rod-like component211of the mesh shelf210is received in the first stop notch108so as to be brought into contact with the bottom of the first stop notch108, the first stop notch108can stop the mesh shelf210from moving toward the trailing end. The transverse rod-like components211can be received in the receptacles113of the first notches111. In this configuration, one of the transverse rod-like components211of the mesh shelf210is received in the second stop notch109. Stopped by the second stop notch109, the mesh shelf210cannot move toward the leading end. In order to additionally stabilize the mesh shelf210on the bracket100, a stop element220may be provided at the trailing end of the bracket100to secure the mesh shelf210(seeFIGS.3and6). As shown inFIG.7, the stop element220includes two washers221and a curved stop tab222. The two washers221are substantially parallel, and are joined by a trailing end224of the stop tab222, to each other. As shown inFIGS.6and7, the washers221are shaped similarly to the lug1011. Equally-sized holes may be provided at aligned locations of the lug1011and the washers221, and the washers221may be fixed to the lug1011by screws inserted in the holes. The fixation may be accomplished otherwise, for example, by welding or riveting. It will be understood that, in the latter case, it is unnecessary to provide the holes in the lug1011and washers221. The stop element220is made of a metal or plastic material with a certain degree of elasticity. The stop tab222is curved, and a curved portion of it defines a receptacle223. When the stop element220is fixedly connected to the bracket100, the receptacle223of the curved stop tab222can receive a transverse rod-like component211, as shown inFIG.8. Specifically, an external force may be applied to deflect the stop tab222to increase a radius of curvature of the curved contour of the stop tab222to expand the receptacle223that it defines to allow the transverse rod-like component211to be received therein. After the force is removed, the stop tab222restores its original shape due to its elasticity. That is, the radius of curvature of the curved contour of the stop tab222decreases. Accordingly, the receptacle223defined by the curved contour shrinks, stopping the transverse rod-like component211within the stop tab222.

As shown inFIGS.2,9and10, a second mating portion120is used to connect a plate-like shelf230. The plate-like shelf230is an integral, continuous, flat plate and may be generally made of wood, plastic, metal, or the like. If the plate-like shelf230is directly placed on the bracket100, it tends to slide on the bracket100in its lengthwise direction and cannot reside stably thereon. The second mating portion120can be used to fix the plate-like shelf230to the bracket100, increasing its stability on the bracket100. The second mating portion120includes at least one through hole121vertically extending through the bottom bracket wall and a fastener122which can be inserted in the through hole. For example, the fastener122may be a long nail, which can be inserted into the through hole121from the bottom of the bracket upwards. After a pointed tip of the long nail is passed through the through hole, the nail may be hammered to drive the tip into the plate-like shelf230. Alternatively, the fastener122may be a screw, which may be passed through the through hole121and screwed into the plate-like shelf230.

As shown inFIGS.1,1112and13, a third mating portion130is used to connect a carrier component240defining a storage space, such as a drawer-like carrier component shown in the illustrated example. As shown inFIGS.1and4, the third mating portion130includes at least one second notch131in the bracket100, which can mate with a third mating component implemented as a first clasp132. In use, the first clasp132is snap-engaged in the second notch131, and a fastener is then used to connect the first clasp132to a side panel241of the carrier component240, thereby securing the carrier component240. The second notch131is recessed from the first side102of the bracket100. As shown inFIGS.14and15, the first clasp132includes a first side wall1321and a second side wall1322, which oppose each other. Top ends of the first side wall1321and the second side wall1322are joined to each other by a top wall1323. The first side wall1321and the second side wall1322define a gap1324therebetween, which allows the clasp to be snap-engaged in the second notch131of the bracket100. The fastener is passed through a through hole1325extending through the second side wall1322in its thickness direction and is then connected to the side panel241of the carrier component240. In some implementations, as shown inFIG.14, the first clasp132further includes an elastic portion1326provided on a surface of the second side wall1322facing the first side wall1321. As shown inFIG.16, when the first clasp132is received in the second notch131, the elastic portion1326abuts against a wall around the second notch131, thereby securely snap-engaging the first clasp132in the second notch131. It will be understood that the carrier component240may be implemented as a drawer (seeFIG.11), cage-like carrier component, basket-like carrier component or other carrier component that defines an internal storage space. All these carrier components240have a storage space in which goods can be stored. That is, they all have an internal volume for storage of goods.

In another implementation, the at least one second notch131may be structured as shown inFIG.17. Opposite end portions of an opening of the second notch131extend toward the interior of the second notch131, thus defining a first extension1311and a second extension1312. A surface of the first extension1311facing the bottom of the second notch131is configured as a slanted surface1313. With this configuration, as shown inFIG.18, the first clasp132must be held obliquely at an angle before it can be inserted into the second notch131. The angle the first clasp132must be held obliquely may be substantially equal to an angle the surface1313is slanted. Once received in the second notch131, the first clasp132will be blocked by the first extension1311and the second extension1312from dislodgement from the second notch131, thereby stabilizing the carrier component. That is to say, blocked by the first extension1311and the second extension1312, the carrier component240must be deployed or removed obliquely, rather than perpendicularly to the lengthwise direction of the bracket. Preferably, the second notch131is arranged around the connecting portion101and structured as shown.

In another implementation, the first clasp132is structured as shown inFIG.19. In the example ofFIG.19, the first clasp132includes only a first side wall1321and a second side wall1322. Top ends of the first side wall1321and the second side wall1322are joined to each other by a top wall1323. The first side wall1321and the second side wall1322define a gap1324therebetween, in which a side wall of the bracket that defines the second notch131can be received. The first side wall1321is elastic and can be biased toward the second side wall1322. Once snap-engaged in the second notch131, the first side wall1321is biased toward the second side wall1322and thereby firmly engaged with the side wall of the bracket that defines the second notch131. Preferably, a locking hole1327is provided on the first side wall, and a locking stud1314which can mate with the locking hole1327is provided on the side wall of the bracket that defines the second notch131(seeFIG.16). The locking stud1314is spherical, projects toward the side wall of the bracket and can snap into the locking hole1327.

As shown inFIGS.2and20, a fourth mating portion140is used to connect a hanging hook250. As shown inFIGS.21and22, the fourth mating portion140includes two through slots141provided at the bottom of the bracket in correspondence with two respective snap tongues on the hanging hook250, namely, a first snap tongue252and a second snap tongue253. The first snap tongue252of the hanging hook250has a projection254projecting in a leading direction of the bracket100. After the first snap tongue252and the second snap tongue253of the hanging hook are passed through the respective through slots141, the hanging hook250can be moved in the leading direction of the bracket100to bring the projections254into abutment with the bottom of the bracket100, thereby securely hanging the hanging hook250on the bracket100. It will be understood that the fourth mating portion140may also be provided as a threaded hole, and a fastener such as a screw may be used to fix the hanging hook250to the bracket100. The hanging hook250includes a hook portion255. Two hanging hooks250may be provided in parallel and opposition to each other, and a hang bar251may be horizontally placed on both the hook portions255of the hanging hooks250

In some implementations, as shown inFIGS.23and24, a cover component260may be provided on the bracket100, which covers the entire mesh shelf210to not only provide protection but also allow goods to be stored thereon.

When the bracket100of the first embodiment is used in a storage rack system, carrier components of different structures may be arranged thereon, as required. As shown, examples of the carrier components may include mesh shelves210, plate-like shelves230, hanging hooks250and other carrier components250defining a storage space. Alternatively, carrier component of the same single structure may be arranged on the bracket100. In the case, the carrier component may be replaced with carrier component of a different structure, as required, without requiring replacement of the bracket.

The bracket100of the first embodiment includes two side walls103, which may be formed by bending a single sheet of material.

As shown inFIG.25, a bracket according to a second embodiment differs from that of the first embodiment in consisting of a single sheet1001. The single sheet may be of the same structure as the first bracket wall105or the second bracket wall106in the bracket of the first embodiment. The sheet1001may define, at its second side103, a notch150for mating with a carrier component. Around the second side103, there is provided a through hole155, through which a fastener may be passed and connected to the carrier component. A through hole (not shown) is provided in the sheet1001, which extends from the second side103to a third side104, and a fastener may be passed through the through hole and connected to a plate-like shelf230. The notch150can mate with a first clasp132for connecting a drawer240.

In one implementation, as shown inFIGS.26,27and28, the bracket100of the second embodiment is provided with a second clasp151, which can mate with the notch150by snap engagement therein. The second clasp151defines a recess156for receiving a transverse rod-like component211of a mesh shelf210, and the mesh shelf210is covered with a plate-like component152.

It will be understood that the bracket of the second embodiment can also define the first, second, third and fourth mating portions of the first embodiment. The connecting portion101and the stop element220of the first embodiment are also applicable to the second embodiment. The brackets of the two embodiments can be connected to a horizontal beam or upright column in the same way. The second clasp151of the second embodiment can also be used in the first embodiment to connect a carrier component.

As noted above, the bracket100of the first embodiment may include a second mating portion120, and a carrier component20may be secured to the bracket100by inserting a fastener (e.g., a screw) through the second mating portion120so that its one end passes through the bracket100from the third side104and then through the carrier component20(e.g., a plate-like shelf230). However, it is to be noted that the bracket100of the first embodiment defines, across its length, a varying between the second side103, with which the carrier component20is to be brought into direct contact, and the opposite third side104, as shown inFIG.29. A fastener30may be passed through the bracket100so that its one end protrudes out of the second side103while the other end remains exposed on the third side104. For example, consider locations M and N in the figure. The bracket100has a greater width at location M than at location N. Therefore, it is obvious that the two locations require the use of fasteners30of different lengths and that a fastener30adeployed at location M must be longer than a fastener30bdeployed at location N. Accordingly, a single storage rack system would require the use of fasteners30of various sizes. This will increase the cost of manufacturing the storage rack system because it is necessary to produce or purchase fasteners30of multiple different sizes, during the manufacturing. Moreover, more effort is required in assembly because the fasteners30of different sizes must be deployed at respective specific locations on the bracket100. Further, during assembly, it is possible for one or more fasteners30to be deployed obliquely in the bracket100and the carrier component20. Consequently, carrier component20may not be stably coupled to the bracket100.

In order to overcome the above problem, a third embodiment provides a bracket assembly10, which allows a carrier component20to be secured to a bracket100thereof using fasteners30of the same size without oblique deployment of any fastener30during assembly. It will be understood that the bracket100of this embodiment is limited to having a triangular shape and may have any other suitable shape. The present application is not limited to any particular shape of the bracket.

Referring toFIG.30, the bracket100is generally triangular and defines, on its shortest side (first side102), a connecting portion101for connecting the bracket100to an upright column300or horizontal beam400. The other two sides (a second side103and a third side104) both extend from the first side102and form an acute angle therebetween. As viewed in the orientation of the figure, the second side103is an upper side, and the third side104is a lower side.

The bracket100may be in the shape of a right triangle, in which the first side102and the second side103cross each other at a right angle. This triangular shape promises higher stability, which can additionally ensure stable coupling of the upright column300, the bracket assembly10and the carrier component20. The bracket100includes a first bracket wall105and a second bracket wall106, which are substantially parallel to each other and both of the same shape as the bracket100. A space between the first bracket wall105and the second bracket wall106defines a mounting cavity1001. It will be understood that, in other implementations, the bracket100may also have any other regular or irregular shape, such as rectangular. In addition, the mounting cavity1001may also be formed in the bracket100by material removal. This embodiment is not particularly limited in this regard, as long as it can be ensured that the bracket assembly10has desirable stability and reliability.

Referring toFIGS.31to33, in the bracket assembly10of this embodiment, the bracket100further includes a guide structure310disposed within the mounting cavity103. A fastener30can pass through the guide structure310in the mounting cavity1001to couple a carrier component20to the bracket100in such a manner that its end away from the carrier component20can extend through both the mounting cavity1001and the guide structure310while the other end does not necessary remain exposed on the third side104of the bracket100. In this way, fasteners30of the same length dimension can be used at various locations on the bracket100, facilitating user operation. Preferably, the guide structure310defines a through hole311adapted for passage of the fastener30therethrough. The through hole311has a radial dimension, which is smaller than a dimension of the end of the fastener30away from the carrier component20and is greater than or equal to a dimension of the end of the fastener30oriented toward the carrier component20. A distance between the through hole311and the second side103of the bracket100may be adapted to the size of a fastener30to be used so that the fastener30to be deployed in the through hole311may be of the same size as another fastener30deployed at a different locations on the bracket. The fastener30may be passed through the through hole311so that its end away from the carrier component20is blocked by an edge of the through hole311while the other end oriented toward the carrier component20is successively inserted through the through hole311and the second side103of the bracket100possibly into the carrier component20. Specifically, as shown, without the guide structure310in the bracket100, a fastener30would have been deployed so that its one end passes through the second side103of the bracket100while the other end remains on the third side104of the bracket100. In the shown example, the bracket100has a greater width at location M than at location N, requiring the use of fasteners30of different lengths. In this case, the guide structure310may be deployed at location M, and a fastener30may be inserted into the bracket100so that its end away from the carrier component20is received within the through hole311of the guide structure310but not exposed outside of the bracket100. At the same time, the distance between the through hole311of the guide structure310and the second side103of the bracket100can be adapted to the size of the fastener30, another fastener30of the same size as that deployed at location M can be deployed at location N.

In some implementations, as shown inFIGS.34to36, the guide structure310includes a guide channel312extending in the same direction as a first predetermined direction (labeled as +J in the figure) in which a fastener30is intended to be deployed. The guide channel312may be located below or above the through hole311(i.e., the guide channel312is arranged in line with the through hole311in the direction in which the fastener30is to be deployed). Opposite ends of the guide channel312define openings3121,3122. The fastener30may be inserted into the guide channel312from the opening3122, through the guide channel312and out of the guide channel312from the other opening3121. After that, it is further inserted through the through hole311in the guide structure310. The guide channel312can ensure that the fastener30will not be deployed obliquely. In the guide structure310, the guide channel312may be spaced apart from the through hole311. That is, as shown inFIG.36, there may be a gap313between the guide channel312and the through hole311. It will be understood that the guide channel312may be directly formed integrally with the through hole311. That is, the through hole311is located at the opening of the guide channel312closer to the carrier component20so to be open into the through hole311(i.e., the through hole311can be considered as part of the guide channel312). It will be also understood that, although there is no other component between the through hole311and the second side103of the bracket100in the shown example, it is also possible to arrange the guide channel312or a similar component between the through hole311and the second side of the bracket.

In some implementations, the guide structure310is formed integrally with the bracket100. That is, the guide structure310forms an inseparable part of the bracket100. For example, the through hole311and/or the guide channel312, through which a fastener30can be passed, may be provided in an projection disposed within the mounting cavity1001of the bracket100. Alternatively, the guide structure310may be defined by a bent inner wall extension of the bracket100.

In some implementations, as shown inFIGS.37and38, the guide structure310may be a component separate from the bracket100. Specifically, the guide structure310may be made up of a guide member314including a connecting portion3141and a guide portion3142, which are joined to each other. The connecting portion3141is coupled to the bracket, and may define the through hole311. The guide portion3142extends from the connecting portion3141in the first predetermined direction ±J and may define the guide channel312. It will be understood that a gap313may be formed between the guide portion3142and the through hole311to separate the guide channel312from the through hole311. Alternatively, there may be no gap between the guide portion3142and the through hole311. That is, the through hole311may be located exactly at the adjacent end of the guide portion3142. In this case, the through hole311provides one opening of the guide channel312of the guide portion3142. Providing the guide structure310as a component separate from the bracket100allows the guide structure310to be used on legacy brackets not provided or formed with such guide structures310. This can retrofit the legacy brackets at low cost and expand the scope of application of the guide structure310.

In order to enable the carrier component20to be secured to the bracket using a fastener30, a hole allowing the fastener30to be inserted therethrough is generally formed in the carrier component20beforehand. In order to assemble the carrier component20, the hole in the carrier component20is first aligned with a corresponding hole in the second side of the bracket, and the fastener30is then successively passed through the hole in the bracket and that in the carrier component20. In order to allow the carrier component20to be readily positioned on the bracket at a correct location where the hole in the carrier component20is aligned with that in the bracket, as shown, in this embodiment, the bracket also has a locating portion315which extends out of the mounting cavity1001of the bracket and can come into contact with the carrier component20. In order to assemble the carrier component20with the bracket, a side wall of the carrier component20may be first brought into abutment against the locating portion315to place the carrier component20at a correct location where the assembly hole in the carrier component20is aligned with the through hole311of the guide structure310on the bracket. This avoids repeated alignment attempts possibly made during assembly, thus facilitating the assembly process. In some implementations, the locating portion315may be integrally formed with the bracket. In some implementations, as shown, the locating portion315may be provided by the guide member314. Specifically, the locating portion315may be joined to the connecting portion3141, preferably in the vicinity of an end thereof proximate the upright column, so as to extend out of the mounting cavity1001of the bracket.

According to this embodiment, instead of a single guide structure310as shown, a plurality of guide structures310may be provided on the bracket100, if required. In addition, it is to be noted that, according to the present embodiment, the carrier component20is not limited to being implemented as a plate-like shelf as shown. The carrier component20may be in any other suitable form to be coupled with a fastener30, without departing from the scope of the present embodiment.

The guide structure310in the bracket assembly of this embodiment allows fasteners30of the same size to be used at various locations on the bracket, without needing to consider the influence of factors including the shape and dimensions of the bracket. This results in reductions in manufacturing cost and facilitates assembly by a user.

As noted above, the first side102of the bracket100shown inFIG.1is configured to allow the bracket to be coupled to an upright column300or horizontal beam400. This may be accomplished by inserting a lug1011projecting from the first side102into a slot301in the upright column300or horizontal beam400. Preferably, as shown, a pair of lugs1011is provided on the first side102, each including an insertion section and an engagement section. In order to assemble the bracket100with an upright column300, the lugs1011may be inserted into slots301in the upright column300and then lowered a small distance by an external force or the bracket's gravity so that the engagement sections engage a wall portion around the slots301. In order to detach the bracket100, the bracket100may be raised a small distance to disengage the engagement sections from the wall portion around the slots301, and the lugs1011may be then pulled out of the slots301. In other implementations, the lugs1011may also be engaged with the slots301by plug-in, threaded or other connections.

In order to more stably couple the bracket100to an upright column300or horizontal beam400, as shown inFIGS.39,40,41and43, a fourth embodiment provides a bracket assembly10further including an anti-dislodgement structure410capable of preventing the lugs1011of the bracket100from dislodging from slots301in the upright column300or horizontal beam400, thereby stabilizing the bracket100. The anti-dislodgement structure410includes a stop element411disposed within the mounting cavity1001so as to be slidable in a second predetermined direction (+K). The stop element411can extend toward the upright column300or horizontal beam400in the lengthwise direction of the bracket100out of the first side102of the bracket100so that its end located outside engages with a slot301in the upright column300or horizontal beam400, thereby restricting the lugs1011from dislodgement from the slots301. After the lugs1011engage the slots301, the stop element411may be caused to slide so that its said end is inserted into the slot301. By doing so, the bracket100cannot move relative to the upright column300in its lengthwise direction, preventing inadvertent dislodgement of the lugs1011from the slots301, which may cause fall off of the bracket100. In this way, the bracket100can be more reliably coupled to the upright column300without relative wobbling, stabilizing both the bracket100and the carrier component20. In order to detach the bracket100from the upright column300, the stop element411may be caused to slide away from the slot301in the opposite direction, followed by disengaging the lugs1011from the slots301. The second predetermined direction may be exactly the shown ±K direction, or inclined at a small angle with respect to the +Y direction, as long as the stop element411is allowed to slide in the second predetermined direction into or away from the slot301in the upright column or horizontal beam.

In this embodiment, referring toFIGS.42and43, the first wall and/or the second wall of the bracket100define(s) first slide slot(s)412extending in the second predetermined direction (or in a direction inclined at a small angle with respect to the second predetermined direction). The stop element411includes a stop portion413and a slide portion414, which are joined to each other. The slide portion414is disposed so as to be able to slide within the first slide slot(s)412to cause the stop portion413to extend out of the bracket100, or retract it back into the mounting cavity1001of the bracket100. Preferably, the slide portion414is generally elongate in shape, and the stop portion413is joined to an end of the slide portion414. The stop portion413may be integrally formed with the slide portion414. The first slide slot(s)412may define a direction in which the slide portion414is slidable, thereby ensuring that the stop portion413slides always in this predefined direction. The slide portion414can slide in the −K direction within the first slide slot(s)412to extend out of the mounting cavity1001into the slot301in the upright column or horizontal beam. The slide portion414can also slide in the +K direction within the first slide slot(s)412away from the slot301back into the mounting cavity1001. In some implementations, as shown inFIG.44, a first avoidance slot416is provided in the bottom wall107of the bracket100, and the stop element411further has a manipulation portion415which is joined to the slide portion414and at least partially protrudes out of the bracket100through the first avoidance slot416. A user can push or pull the manipulation portion415to cause the slide portion414to slide within the slide slot(s) without needing to insert his/her finger into the mounting cavity1001or use any tool. Therefore, the user's operation can be facilitated.

Similar to the fourth embodiment, a fifth embodiment of this application also includes a stop element which can be driven by an external force to move out of or back into the bracket so that a stop portion of the stop element is inserted into or pulled out of a slot in the upright column or horizontal beam. The two embodiments differ in how the stop element is actuated to slide.FIGS.45to56show the structure of the fifth embodiment.

According to the fifth embodiment, as shown inFIGS.45to49, an anti-dislodgement structure410includes a support member510disposed on the first bracket wall105and/or the second bracket wall106of the bracket100. The support member510defines a second slide slot511extending in the second predetermined direction. The anti-dislodgement structure410further includes a stop element512disposed so as to be able to slide in the second slide slot511. The support member510serves to support the stop element512, and the second slide slot511defines a direction in which the stop element512is slidable, thereby ensuring that the stop element512slides always in the second predetermined direction. The stop element512includes a stop portion513and a slide portion514, which are joined to each other. The slide portion514is generally cylindrical in shape and defines a first thread5141. The stop portion513is disposed at one end of the slide portion514and can extend out of the first side102from the mounting cavity1001of the bracket100into a slot301in an upright column or horizontal beam. The anti-dislodgement structure410further includes a manipulation portion515which is annular in shape and disposed over the stop portion513. The manipulation portion515defines on its inner circumferential surface a second thread5151in engagement with the first thread5141. Due to the engagement of the threads, rotating the manipulation portion515can cause the stop portion513to slide within the second slide slot511out of or back into the bracket100. The threaded engagement of the manipulation portion515and the stop element512can prevent inadvertent sliding of the stop element512in the +K direction under the action of an external force, which may cause inadvertent dislodgement of the stop element512from the slot301in the upright column. Therefore, the stop element512can be coupled to the upright column300with higher reliability. The manipulation portion515can be rotated to actuate the slide portion514to slide in the −K direction, causing the stop portion513to move out of the mounting cavity1001into the slot301. The manipulation portion515can also be rotated in the opposite direction to drive the slide portion514to slide in the +K direction slide, causing the stop portion513to move out of the slot301back into the mounting cavity1001. As shown inFIG.48, the first bracket wall105and/or the second bracket wall106of the bracket100define(s) second avoidance slot(s)516. Preferably, two second avoidance slots516are defined in alignment with each other respectively in the first bracket wall105and the second bracket wall106. The support member510includes a first support portion517and a second support portion518. The first support portion517is disposed at one of the second avoidance slots516, and the second support portion518is disposed at the other second avoidance slot516. The first support portion517and the second support portion518are disposed in opposition, and connected, to each other to form the support member510so that the support member510defines an internal receptacle524(seeFIG.50) in which the manipulation portion515and the stop element512are at least partially received. In addition, the first support portion517and the second support portion518respectively define third avoidance slots519, in which an outer circumferential surface of the annular manipulation portion515is at least partially exposed to allow a user to rotate the manipulation portion515. Preferably, the manipulation portion515defines an anti-slip structure535on the outer circumferential surface, which may be composed of, for example, an uneven texture, bumps, ribs, grooves or the like formed in or on the outer circumferential surface. The anti-slip structure535allows a user to rotate the manipulation portion515with increased friction, which avoids difficult rotation of the manipulation portion515by the user due to slippage of his/or finger(s) on the manipulation portion515. It will be understood that the anti-slip structure535may be any structure known in the art which can increase friction between the user's finger(s) and the outer circumferential surface of the manipulation portion515. The present embodiment is not particularly limited in this regard.

Referring toFIGS.51to56, the first support portion517includes a first cap portion520and at least one first protrusion521projecting from a side surface of the first cap portion520. The first cap portion520is disposed at the second avoidance slot516in the first bracket wall105, and the first protrusion521extends from the first cap portion520toward an opposite surface of the mounting cavity1001. Preferably, two first protrusions521are included, which extend in parallel to each other. Similarly, the second support portion518includes a second cap portion522and at least one second protrusion523projecting from a side surface of the second cap portion522. The second cap portion522is disposed at the second avoidance slot516in the second bracket wall106, and the second protrusion523extends from the second cap portion522toward an opposite surface of the mounting cavity1001. Preferably, two second protrusions523are included, which extend in parallel to each other. The first cap portion520and the second cap portion522can be mounted in the first bracket wall105and the second bracket wall106, respectively, so that the first protrusions521come into contact with the second protrusions523and together delimit the receptacle524of the support member510. The third avoidance slots519are respectively defined by the first cap portion520and the second cap portion522so as to both communicate with the receptacle524. The manipulation portion515is received in the receptacle524so that its outer circumferential surface is at least partially exposed in the third avoidance slots519and accessible by a user from the outside of the bracket100. Locating posts525are provided on end faces of the first protrusions521facing the second protrusions523, and locating holes526are provided in end faces of the second protrusions523facing the first protrusions521. The locating posts525can inserted into the locating holes526, thereby connecting the first protrusions521and the second protrusions523together. The second slide slot511is defined by the first protrusions521and the second protrusions523. Specifically, third notches527are provided in the end faces of the first protrusions521facing the second protrusions523, and fourth notches528are provided in the end faces of the second protrusions523facing the first protrusions521. When the protrusions are connected together, the third notches527and the fourth notches528make up the second slide slot511. The slide portion514is passed through the second slide slot511so as to be confined and slidable therein. Inner walls of the third notches527and the fourth notches528respectively have first cut surfaces530, and the slide portion514have a second cut surface531opposing the first cut surfaces530. The second cut surfaces531extend in a lengthwise direction of the slide portion514and are not threaded. That is, the second cut surface531is a smooth surface. The second cut surface531contacts the first cut surfaces530, with a slidable fit being formed therebetween. The slidable fit between the first cut surfaces530and the second cut surface531can prevent the stop element512from rotating in synchronization with the manipulation portion515, ensuring that the stop element512can only slide in the second predetermined direction with respect to the bracket as a result of rotation of the manipulation portion515. Preferably, the inner walls of the third notches527and the fourth notches528also respectively have third cut surfaces532opposing the first cut surfaces530, and the slide portion514also has a fourth cut surface533opposing the second cut surface531. A slidable fit is formed between the fourth cut surface533and the third cut surfaces532.

Although the support member510has been described above as a component separate from the bracket100, it will be understood that the support member510may alternatively be integrally formed with the bracket100. That is, the support member510may form an inseparable part of the bracket100.

In some implementations, as shown inFIGS.45and48, the anti-dislodgement structure410further includes cover(s)534disposed over the second avoidance slot(s)516in the first bracket wall105and/or the second bracket wall106of the bracket100. When it is not necessary to rotate the manipulation portion515, the cover(s)534may be disposed over the second avoidance slot(s)516to conceal the manipulation portion515, avoiding inadvertent dislodgement of the stop element512from the slot301caused by a user's inadvertent touch of the manipulation portion515. This can also provide protection to the manipulation portion515, the stop element512and other internal structures.

In a sixth embodiment of the present application, there is provided a length-adjustable bracket assembly10. As shown inFIGS.57to61, the bracket assembly10includes a bracket100and an adjustment member540disposed at an end of the bracket100away from an upright column. The adjustment member540is movable relative to the bracket100into or out of its mounting cavity1001, thus varying its length. The bracket100has a longer length when the adjustment member540extends out of the mounting cavity1001. The bracket100has a shorter length when the adjustment member540is received within the mounting cavity1001.

In some implementations, as shown inFIGS.57to59, the adjustment member540is pivotally attached to the bracket100. Specifically, the adjustment member540has a first end541and a second end542, which oppose each other. At locations close to the first end541, pivot holes543are provided, through which a pivot shaft544can be passed. The pivot shaft544can be successively inserted through the pivot holes543in the adjustment member540and corresponding holes in the bracket so that the adjustment member540can pivot about the pivot shaft544. The adjustment member540can be pivoted so that its second end542can move into or out of the mounting cavity1001of the bracket100. In order to restrict adjustment member540at defined positions, locating holes are provided in the adjustment member540, and locating protrusions548capable of engaging with the locating holes are provided at corresponding locations on the bracket100. The locating holes include a first locating hole546and a second locating hole547, which are located on opposite sides of the pivot holes543in the lengthwise direction of the bracket. Engagement of the first locating holes546with the locating protrusions548means pivot of the adjustment member540in place into the mounting cavity1001. Engagement of the second locating holes547with the locating protrusions548means pivot of the adjustment member540in place away from the bracket. The engagement of the locating holes with the locating protrusions548can retain the adjustment member at the defined positions.

In some implementations, as shown inFIGS.60to61, the adjustment member540may also be slidably coupled to the bracket100. Specifically, the adjustment member540has a first end541and a second end542, which oppose each other. Sliders549are provided at locations close to the second end542, and the bracket100defines, at corresponding locations, slide slots550extending in its lengthwise direction. The sliders549can slide within the slide slots550. The adjustment member540can be actuated to move within the slide slots550so that its second end542moves into or out of the mounting cavity1001of the bracket100. A length of the slide slot550defines a distance the adjustment member540can slide. Each slide slot550defines in its lengthwise direction a first end portion551and a second end portion552. The first end portions551and the second end portions552can block further sliding of the sliders549. The adjustment member540defines locating holes553, and the bracket defines first locating protrusions554and second locating protrusions555, which can engage with the locating holes. Engagement of the locating holes553with the locating protrusions means not only movement of the sliders549in place but also retention of the adjustment member540at the defined positions. Arrival of the sliders549at the first end portions551of the slide slots550means sliding of the adjustment member540in place into the mounting cavity1001and is accompanied by engagement of the locating holes553with the first locating protrusions554, which retains the adjustment member540at the current position. Arrival of the sliders549at the second end portions552of the slide slots550means outward sliding of the adjustment member540in place away from the bracket100and is accompanied by engagement of the locating holes553with the second locating protrusions555, which retains the adjustment member540at the current position.

It will be understood that the adjustment member is not limited to being retained at the aforementioned positions by engagement of the locating holes with the locating protrusions according to any of the above implementations, and any other suitable configuration capable of locating and retaining the adjustment member can be suitably used.

The adjustment member allows the bracket to have a varying length, making it usable in a wider range of applications. That is, it expands the bracket's scope of application.

II. Storage Rack System

As shown inFIGS.62to64, the present application provides a storage rack system1including upright columns300, horizontal beams400, brackets100as discussed above and carrier components arranged on the brackets100.

The horizontal beams400are usually fixed to a vertical surface, such as a wall surface or a panel surface. The horizontal beams400are generally conventional standard products, which are elongate in shape. In use, the horizontal beams400are often fixed to a vertical surface and not relocated once fixed. The structure of the storage rack system can be structurally modified mainly by adding new upright columns300, or removing or relocating some upright columns300. Therefore, the upright columns300are detachable and movable. Each bracket100is connected, by the connecting portion on its one end, to an upright column300. In some embodiments, the brackets100may also be connected to the horizontal beams400. The structurally different mating portions of the brackets100can be connected to carrier components of different structures. For example, in the example shown inFIG.26, carrier components including mesh shelves210, drawers240, plate-like shelves230and hanging hooks250can be arranged on the brackets100. Carrier components of different structures may be arranged on opposite sides of one or more brackets100. For example, as shown in part X ofFIG.26, a bracket100is connected to a mesh shelf210on one side and to a drawer240on the other side. As shown in port Y ofFIG.26, a plate-like shelf230is arranged on and connected to a bracket100, and a hanging hook250is arranged under and connected to the bracket100.

It will be understood that the storage rack system may be provided with carrier components of the same single structure, which may be replaced with carrier components of a different structure without requiring replacement of the brackets100.

As shown inFIGS.6and8, the upright columns300define slots301, and the lugs1011of the brackets100can fixedly engage in the slots301.

Usually, the storage rack system1may include at least two upright columns300arranged in parallel at an interval. At least one bracket assembly10, e.g., a plurality of bracket assemblies10, may be arranged on each upright column300, e.g., at intervals, in a heightwise direction of the upright column300. As noted above, one or more carrier components20may be arranged on a single bracket assembly10. Alternatively, a single carrier component20may be coupled to at least two bracket assemblies10arranged at the same height. In this way, the carrier component20can be more stably retained. For example, as shown inFIG.64, the lowermost carrier component20in the storage rack system1horizontally spans three bracket assemblies at the same height.

According to an eight embodiment, as shown inFIG.65, a carrier component20is attached to a bracket100via a guide rail600in such a manner that it can be moved outwardly or inwardly in a lengthwise direction of the bracket100. This not only allows a user to more easily pick up an item from the carrier component20, but can also reduce the space that the storage rack system occupies. In some implementations, the carrier component20may be a container like a mesh basket.

As shown inFIG.66, the bracket100has a fifth mating portion on its second side103. The fifth mating portion includes a plurality of fifth notches601which are formed in the second side103at intervals in the lengthwise direction. As shown, according to this embodiment, the storage rack system includes the guide rail600including a guide rail body608and a plurality of engagement elements602protruding from the guide rail body608. Each of the engagement elements602can engage in one of the fifth notches601, thereby attaching the guide rail600to the bracket100. The engagement of the engagement elements602and the fifth notches601can ensure stable and reliable attachment of the guide rail600to the bracket100.

Referring toFIG.66, each fifth notch601defines a first engagement portion6011and a second engagement portion6012respectively at its ends opposing in the +K direction.

In some implementations, as shown inFIGS.67and68, the engagement elements602include rivets603each including a diametrically smaller portion604attached to the guide rail body608and a diametrically larger portion605joined to the end of the diametrically smaller portion604away from the guide rail body608. The diametrically smaller portion604has a dimension smaller than or equal to a dimension of the fifth notches601, and the diametrically larger portion605has a dimension greater than that of the fifth notches601. In order to deploy the guide rail600, the diametrically smaller portions604of the rivets603can be passed through openings of the fifth notches601and engaged with the first engagement portions6011of the fifth notches601, while the diametrically larger portions605can prevent the engagement elements602from inadvertently disengaging from the fifth notches601.

In some implementations, as shown inFIGS.69to71, the engagement elements602includes engagement hooks606, which can be inserted into the fifth notches601and engage the first engagement portions6011thereof. Of course, in other implementations, both the rivets603and the engagement hooks606may be provided on the guide rail body608. The engagement of the rivets603or engagement hooks606with the first engagement portions6011of the fifth notches601enable easy and convenient assembly without needing the use of additional fasteners such as screws or bolts.

In some implementations, referring toFIGS.70and71, the guide rail600further includes stoppers607protruding from the guide rail body608. In the direction in which the carrier component20is slidable, the second engagement portion6012and the first engagement portion6011at opposite ends of each fifth notch601are engaged with one of the stoppers607and one of the engagement elements602, respectively. The engagement of the engagement elements602with the first engagement portions6011of the fifth notches601is established before the engagement of the stoppers607with the second engagement portions6012of the fifth notches601. By doing so, the engagement elements602cannot move within the fifth notches601, avoiding fall off of the carrier component20from the guide rail600due to inadvertent disengagement of the engagement elements602from the fifth notches601. Thus, the guide rail600can be more reliably attached to the bracket100. Meanwhile, wobbling of the guide rail600relative to the bracket100can be prevented, additionally stabilizing the guide rail600and the carrier component20. In order to detach the carrier component20and the guide rail600, the stoppers607may be disengaged from the fifth notches601, allowing the engagement elements602to move within the fifth notches601. After that, the engagement elements602may be disengaged from the fifth notches601, allowing the guide rail600and the carrier component20to be removed from the bracket100. In some implementations, as shown inFIG.66, the stoppers607and the engagement elements602engage in different fifth notches601. That is, the engagement elements602engage the first engagement portions6011of some fifth notches601, and the stoppers607engage the second engagement portions6012of other fifth notches601.

The number of fifth notches601may be determined, as required. Two, three or four fifth notches601may be provided. The plurality of fifth notches601may be provided at any suitable locations, depending on the arrangement of the engagement elements602and stoppers607of the guide rail600, as long as it is ensured that all the engagement elements602and the stoppers607can engage in the fifth notches601. The present embodiment is not particularly limited in this regard. Although the carrier component20is shown as an open mesh basket, it will be understood that it may be in any other suitable form that allows it to be attached to the bracket100through the guide rail600. The present embodiment is not limited to any particular configuration of the carrier component20.
