## Title
Device for holding a container

## Abstract

A device for holding a container includes a base configured to support the container, a retaining mechanism configured to retain the container relative to the base, and an actuator mechanism coupled to the retaining mechanism. The retaining mechanism includes an iris moveable between an insertion position and a retaining position. A central opening formed by the iris in the insertion position has an insertion diameter greater than a retaining diameter of the central opening formed by the iris in the retaining position. The iris includes a plurality of arms arranged in a first level and a second level. User rotation of the actuator mechanism in a first direction causes the arms of the iris to move to the retaining position, and in a second direction opposite the first direction causes the arms of the iris to move away from the retaining position towards the insertion position.

## Background
BACKGROUND
a. Technical Field
The disclosure relates generally to vehicle components, and more particularly, to a device for holding a container.
b. Background Art
This background description is set forth below for the purpose of providing context only. Therefore, any aspects of this background description, to the extent that it does not otherwise qualify as prior art, is neither expressly nor impliedly admitted as prior art against the instant disclosure.
There are several devices for holding containers (e.g., cupholders) for use in vehicles, such as automobiles, aircrafts, and strollers. Some devices contain spring-loaded retainers that protrude through the sidewalls of the device and that are limited in how far they can extend. Moreover, these spring mechanisms may sacrifice stability by providing only point contacts on the container toward the base of the container (rather than the top). Also, greater spring forces may have a tendency to indent or distort softer containers like Styrofoam or thin-walled plastic bottles, while lesser spring forces may offer little resistance to tipping of large containers.
Rubber or elastomer-type cupholder inserts with local, deformable extensions to secure the container may be more robust (with respect to tipping), but may have different issues. For example, because of the higher surface friction between the inserts and the container, a greater force is required to insert and remove the container from the holder. The rubber insert may tend to come out with the container, or the beverage may be spilled when the container finally dislodges from the rubber retainer (as the user may not be able to stop the momentum). The rubber inserts may also cause the user to collapse a weaker container due to the grip force required to remove it from the holder. Another issue with rubber inserts is that the lid may be inadvertently removed from the cup when the user attempts to remove the cup from the holder (i.e., the lid comes up with the user's hand). Improvements are, therefore, desired to address these challenges. Among other things, the instant disclosure seeks to improve upon the aforementioned issues.
The foregoing discussion is intended only to illustrate the present field and should not be taken as a disavowal of claim scope.
SUMMARY
In an embodiment, a device for holding a container includes a base configured to support the container, a retaining mechanism configured to retain the container relative to the base, and an actuator mechanism coupled to the retaining mechanism. The retaining mechanism includes a longitudinal axis and an iris moveable between an insertion position and a retaining position. A central opening formed by the iris in the insertion position has an insertion diameter greater than a retaining diameter of the central opening formed by the iris in the retaining position. The iris includes a plurality of arms arranged in a first level and a second level. User rotation of the actuator mechanism in a first direction causes the arms of the iris to move to the retaining position, and user rotation of the actuator mechanism in a second direction opposite the first direction causes the arms of the iris to move away from the retaining position towards the insertion position.
An advantage of the embodiments described herein is that the device can accommodate containers with various diameters as per the user's desire (i.e., device is user-adjustable). Additionally, the device closes the clearance between the container and sidewall of the device, which generates a clean appearance from above and prevents objects from getting between them. Furthermore, the devices described herein allow for greater surface contact with the container, and the contact surfaces are more uniformly distributed about the circumference of the container farther away from the base of the container. In additional embodiments, for vehicles equipped with heated and/or cooled cupholders, the devices described herein help to minimize convective heat dissipation by closing off an area around the container. These advantages aid in improving the aforementioned issues.
The foregoing and other aspects, features, details, utilities, and advantages of the present disclosure will be apparent from reading the following description and claims, and from reviewing the accompanying drawings.

DETAILED DESCRIPTION
Various embodiments are described herein to various apparatuses, systems, and/or methods. Numerous specific details are set forth to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments as described in the specification and illustrated in the accompanying drawings. It will be understood by those skilled in the art, however, that the embodiments may be practiced without such specific details. In other instances, well-known operations, components, and elements have not been described in detail so as not to obscure the embodiments described in the specification. Those of ordinary skill in the art will understand that the embodiments described and illustrated herein are non-limiting examples, and thus it can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments.
Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” or “an embodiment,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” or “in an embodiment,” or the like, in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Thus, the particular features, structures, or characteristics illustrated or described in connection with one embodiment may be combined, in whole or in part, with the features, structures, or characteristics of one or more other embodiments without limitation given that such combination is not illogical or non-functional.
Referring now to the drawings wherein like reference numerals are used to identify identical or similar components in the various views, FIG. 1 is an isometric view of a device 20 for holding a container (not shown), wherein device 20 is in an insertion position, in accordance with an embodiment of the instant disclosure. FIG. 2 is an isometric view of device 20 in a retaining position. Device 20 may be configured to move from the insertion position to the retaining position (or any position therebetween) upon actuation by a user or system. Device 20 may also be configured to move from the retaining position to the insertion position (or any position therebetween) upon actuation by a user or system (for example and without limitation, spring-loaded rocker arms or switch activated motor).
Device 20 defines a central opening 21 configured to receive a container or beverage, opening 21 being user-adjustable. As shown in FIGS. 1-2, the size of opening 21 changes as device 20 moves to/from the insertion and retaining positions. When in the insertion position (FIG. 1), opening 21 has an insertion diameter 22; when in the retaining position (FIG. 2), opening 21′ has a retaining diameter 22′ that is less than insertion diameter 22. As such, device 20 can accommodate containers having diameters associated with the insertion position, the retaining position, or any intermediate position therebetween. Once a container or beverage is inserted into device 20, device 20 may be moved from the insertion position toward the retaining position. Depending on its size, the container or beverage may prevent device 20 from moving completely to the retaining position illustrated in FIG. 2 (i.e., the container may cause device 20 to only reach an intermediate position). Once the device 20 is in the retaining position (or an intermediate position), the container may be removed and re-inserted repeatedly without having to move the device 20 to the insertion position.
FIG. 3 is an exploded isometric view of device 20. Device 20 may comprise a retaining mechanism 23, an actuator mechanism 24, and a receptacle 26. Retaining mechanism 23 includes central opening 21 and may comprise a longitudinal axis 28 and an iris 30 movable between the insertion position (FIG. 1) and the retaining position (FIG. 2). Iris 30 may comprise a plurality of arms 32, 34 arranged in levels 36, 38. Arms 32 in level 36 may be axially disposed between actuator mechanism 24 and arms 34 of level 38. Arms 34 of level 38 may be axially disposed between arms 32 of level 36 and receptacle 26. As more particularly shown, arms 32 of level 36 may comprise a plurality of arms 321-3, and arms 34 of level 38 may comprise a plurality of arms 341-3.
A detailed explanation of the various components of device 20 follows. Thereafter, this disclosure will describe how the various components are assembled to form device 20. Lastly, this disclosure will describe how device 20 operates and how the various components thereof interact with one another.
FIGS. 4A-4C illustrate various views of receptacle 26 of device 20. Receptacle 26 may define an opening 58 and may comprise a base 60, a sidewall 62, a flange 64, pivots 541-3, 561-3 disposed on flange 64, and stops 661-3. Base 60 may be configured to support the container. Sidewall 62 may extend axially from base 60 and may be generally cylindrical in shape. Sidewall 62 defines a cavity 68 in which the container may reside. Flange 64 may be configured to support actuator mechanism 24 and arms 321-3, 341-3 of iris 30 (shown in FIG. 3). Flange 64 may be disposed at a longitudinal end 70 of receptacle 26 opposite of base 60. Pivots 541-3, 561-3 may be generally cylindrical in shape and be arranged equidistantly around a circumference 65 of flange 64. Stops 661-3 may be configured to prevent further rotation of actuator mechanism 24. In the illustrated embodiment, stops 661-3 project radially outwardly from flange 64 and are arranged equidistantly around the perimeter of flange 64.
FIGS. 5A-5D illustrate various views of arm 341. In the illustrated embodiment, arms 342, 3 are identical to arm 341. In other embodiments, however, arms 341-3 of level 38 of iris 30 may not be identical to one another (in shape and/or function). Arm 341 is configured to pivot radially inwardly to contact the container. In the illustrated embodiment, arm 341 generally may be curved in shape and may comprise a top surface 72k, an inner edge 741 configured to contact the container, an outer edge 761 opposite of inner edge 741, an aperture 781, a slot 801 extending radially inwardly from outer edge 761, and an arm guide 821. Slot 801 may be disposed generally between a midpoint 841 of arm 341 and a longitudinal end 861 of arm 341. Arm guide 821 may have longitudinal ends 88k, 881′. Arm guide 821 may also be a through hole and may be disposed between slot 801 and a longitudinal end 901 of arm 341. Arm guide 821 may also be curved. One of ordinary skill in the art will understand that the dimensions, curvature, and positioning of arm guides 821-3 may have certain dependencies, namely, the size of arms 321-3, 341-3, the desired diameters for the retaining and insertion positions, and the effort needed from the user or system to actuate the device, among other things. Moreover, although arm guides 821-3 are illustrated as being identical in shape and size, arm guides may be of different shapes and sizes, depending on the actuation desired.
FIGS. 6A-6D illustrate various views of arm 321. In the illustrated embodiment, arms 322, 3 are identical to arm 321. In other embodiments, however, arms 321-3 of level 36 of iris 30 may not be identical to one another (in shape and/or function). Arm 321 is configured to pivot radially inwardly to contact the container. In the illustrated embodiment, arm 321 generally may be curved in shape and may comprise a top surface 96k, a bottom surface 98k, an inner edge 1001 configured to contact the container, an aperture 1021, an actuating cam 1041 projecting axially upwardly from top surface 961, and an arm cam 1061 projecting axially downwardly from bottom surface 981. Actuating cam 1041, which may be cylindrical in shape, may be configured to engage with actuator mechanism 24 (shown in FIG. 3). Actuating cam 1041 may be disposed at a longitudinal end 1081 of arm 321, and aperture 1021 may be disposed at a longitudinal end 1101 of arm 321, opposite of longitudinal end 1081. Arm cam 1061 may be generally cylindrical in shape and may be configured to engage with arm 341 below arm 321. Arm cam 1061 may be disposed generally between a midpoint 1161 of arm 321 and longitudinal end 1101 of arm 321.
FIG. 7 is a bottom isometric view of actuator mechanism 24. Actuator mechanism 24 is configured to allow a user or system to move arms 321-3, 341-3 so as to assume one of the insertion position and the retaining position (or an intermediate position therebetween). In the illustrated embodiment, actuator mechanism 24 is a ring 136. Ring 136 may comprise an outer wall 138, slots 1401-3 disposed therein, attachment clips 1421-3, and actuating guides 1441-3 formed in a bottom surface 146 of ring 136. Slots 1401-3 may be arranged equidistantly around outer wall 138. Attachment clips 1421-3 may be configured to facilitate coupling of ring 136 to receptacle 26. Attachment clips 1421-3 may each have a projection 1481-3 that projects radially inwardly. Actuating guides 1441-3 are configured to engage with arms 321-3, respectively. Actuating guides 1441-3 may each have longitudinal ends 1491-3, 1491-3′. In the illustrated embodiment, actuating guides 1441-3 are curved and are arranged circumferentially equidistantly on bottom surface 146 of ring 136. In an embodiment, actuating guides 1441-3 may have a width 150 of four millimeters, and longitudinal ends 1491-3, 1491-3′ may have an inner radius of curvature 152a of thirty-four millimeters and an outer radius 152b of curvature of thirty-eight millimeters. In one embodiment, a gap 152c between longitudinal end 1491-3′ and an inner edge of ring 136 may be two millimeters. Although specific dimensions are mentioned, one of ordinary skill in the art will understand that the dimensions, curvature, and positioning of actuating guides 1441-3 may have certain dependencies, namely, the size of arms 321-3, the desired diameters for the retaining and insertion positions, and the effort needed from the user or system to actuate the device, among other things. Moreover, although actuating guides 1441-3 are illustrated as being identical in shape and size, actuating guides may be of different shapes and sizes, depending on the actuation desired.
A description of how the components of device 20 are assembled is now provided. FIG. 8 illustrates device 20 in various stages of assembly. Flange 64 of receptacle 26 may serve as the base for arms 321-3, 341-3 and for ring 136. Each pivot 541-3, 561-3 on flange 64 may extend through a corresponding arm 321-3, 341-3, respectively. In the illustrated embodiment, there are six pivots 541-3, 561-3, one for each arm 321-3, 341-3 of iris 30, respectively. In other embodiments, however, one pivot may extend through more than one arm (and serve as a pivot for those arms). Pivots 541-3 may have a height 147 measured from top surface 70 of flange 64, and pivots 561-3 may have a height 148 measured from top surface 70 of flange 64. In the illustrated embodiment, height 147 of pivots 541-3 is greater than height 148 of pivots 561-3 since pivots 541-3 extend farther up to arms 321-3. Also, in the illustrated embodiment, pivots 541-3, 561-3 all lie on a centered circumference 65 of flange 64, which is midway between the inner and outer diameters of flange 64. In other embodiments, however, pivots 541-3, 561-3 may be disposed at various points on flange 64, and may not lie on the same circumference.
Arms 341-3 are coupled to flange 64 via insertion of pivots 561-3 through apertures 781-3 of arms 341-3, respectively, and insertion of pivots 541,2,3 through slots 803,1,2, respectively. Slots 801-3 may be configured to permit pivots 541-3 to extend through arms 341-3 to arms 321-3 but may also be configured to aid in guiding arms 341-3 upon actuation of ring 136. Once coupled, arms 341-3 together extend circumferentially around a substantial portion of flange 64, leaving only gaps 1511-3. Arms 321-3 are coupled to flange 64 and to arms 341-3 via insertion of pivots 541-3 through apertures 1021-3 of arms 321-3, respectively, and insertion of arm cams 1061-3 of arms 321-3 (FIGS. 6C-6D) in arm guides 821-3 of arms 341-3, respectively. In the illustrated embodiment, there are three arm guides 821-3, and each arm guide 821-3 corresponds to an arm cam 1061-3 of arm 321-3 (FIGS. 6C-6D), respectively. Once coupled, arms 321-3 together overlap a majority of the top surfaces of arms 341-3 and also gaps 1511-3. Also, in the illustrated embodiment, the longitudinal ends of arms 321-3 are offset from the longitudinal ends of arms 341-3 such that midpoints 1161-3 of arms 321-3 are disposed over gaps 1511-3. The size and number of gaps can vary; in some embodiments, there may be little to no gaps between the arms.
Still referring to FIG. 8, ring 136 is coupled to receptacle 26 by aligning actuating cams 1041-3 of arms 321-3 with actuating guides 1441-3 (FIG. 7) of ring 136, respectively, and also by aligning stops 661-3 of receptacle 26 with slots 1401-3 of ring 136, respectively. In the illustrated embodiment, there are three actuating guides 1441-3 (FIG. 7), and each actuating guide 1441-3 corresponds to an actuating cam 1041-3 of arm 321-3, respectively. A tapered or radial lead-in may be provided on either actuating guides 1441-3 of ring 136, actuating cams 1041-3 of arms 321-3, or both to allow assembly with minor misalignment. Ring 136 is also coupled to receptacle 26 via attachment clips 1421-3 which are integral with ring 136. Attachment clips 1421-3 will now be described in detail.
FIG. 9 is a partial, enlarged, cross-sectional view of a portion of device 20. As ring 136 is pushed over flange 64, clips 1421-3 bow radially outwardly and then snap radially inwardly such that surfaces 1521-3 of projections 1421-3 engage a lip 153 of flange 64. Once attached, outer wall 138 and bottom surface 146 of ring 136 and top surface 70 of flange 64 define a cavity 154 in which arms 321-3, 341-3 of iris 30 may reside when in the insertion position. Ring 136 may be decoupled from flange 64 by manually bowing clips 1421-3 radially outwardly and removing. In the illustrated embodiment, there are three attachment clips 1421-3; however, more or less clips may be used.
With continual reference to FIG. 8, a description of how device 20 operates will now be provided. In one embodiment, rotation of ring 136 in a first direction 155 causes arms 321-3, 341-3 of iris 30 to close down the size of central opening 21 (i.e., toward the retaining position) (as shown in FIG. 2). Additionally, rotation of ring 136 in a second opposite direction 156 causes arms 321-3, 341-3 of iris 30 to open up to increase the size of central opening 21 (i.e., toward the insertion position). In another embodiment, directions 155, 156 are reversed. Ring 136 may be manually rotated by the user or, alternatively, may be automated using mechanical (e.g., spring-loaded rocker arms) or electro-mechanical (switch activated motor) devices. Although actuator mechanism 24 is illustrated as comprising ring 136, actuator mechanism 24 can take on other forms other than ring 136 (i.e., pivoting of arms 321-3, 341-3 can be actuated by other means).
As ring 136 rotates, actuating guides 1441-3 disposed on bottom surface 146 of ring 136 (FIG. 7) correspondingly rotate relative to axis 28. As such, the movement of actuating guides 1441-3 of ring 136 causes actuating cams 1041-3 of arms 321-3 to move and travel within actuating guides 1441-3, respectively. Such travel causes arms 321-3 to pivot relative to their respective pivots 541-3.
Still referring to FIG. 8, as a result of such pivoting of arms 321-3, arm cams 1061-3 on bottom surface 981-3 of arms 321-3 (FIGS. 6C-6D) move with their respective pivoting arm 321-3 and travel within arm guides 821-3 of arms 341-3, respectively. Such travel causes arms 341-3 to pivot relative to their respective pivots 561-3. In addition, while arms 341-3 pivot radially inwardly or outwardly, pivots 541-3 for the adjacent arm 321-3 (which extend through apertures 1021-3 of arms 321-3) travel within slots 801-3 of arms 341-3. For example, in the illustrated embodiment, pivot 543 extends through aperture 1023 of arm 323 and travels within slot 802 of arm 342. Such travel of pivots 541-3 within slots 801-3 may aid in guiding the pivotal movement of arms 341-3. Dissimilar materials with different coefficients of thermal expansion may be used on interfacing elements to avoid loss of clearance between guides or slots and cams or pivots over the operating temperature range.
Upon moving in either direction 155 or 156, ring 136 will come to a stop through the interaction of stops 661-3 of flange 64 with slots 1401-3 of ring. Stops 661-3 travel within slots 1401-3 until stops 661-3 contact the respective endwalls of slots 1401-3. In the illustrated embodiment, ring 136 comprises three slots 1401-3; however, one of ordinary skill in the art will understand that ring 136 may comprise less or more than three stops 661-3. Furthermore, the ratio of stops to slots may not be one-to-one. In addition, stops 661-3 with or without slots 1401-3 may instead be disposed internally of outer wall 138 of ring 136.
In operation, arms 321-3, 341-3 move synchronously to close the clearance between the container and sidewall 62 of receptacle 26 and/or inner edge of ring 136, which generates a clean appearance from above and prevents objects from falling therebetween.
In the illustrated embodiment, flange 64 is stationary relative to ring 136 and iris 30. As such, pivots 541-3, 561-3 projecting axially from top surface 70 of flange 64 are also stationary relative to iris 30. Although flange 64 is illustrated as being integral with receptacle 26, one of ordinary skill in the art will understand that flange 64 may be a component separate from receptacle 26 and that the device 20 may be provided without the receptacle 26 and/or base 60 and be assembled into a separate cup holder as desired.
In the insertion position, actuating cams 1041-3 of arms 321-3 are disposed at longitudinal ends 1491-3 of actuating guides 1441-3, respectively, in ring 136 (see FIG. 7 for longitudinal end 1491). In the retaining position, actuating cams 1041-3 are disposed at longitudinal ends 1491-3′ of actuating guides 1441-3 (see FIG. 7 for longitudinal end 1491′). Although longitudinal ends 1491-3, 1491-3′ correspond to the positions of actuating cams 1041-3 when device 20 is in the insertion and retaining positions, respectively, other positions within actuating guides 1441-3 may correspond to the insertion and retaining positions. Furthermore, although actuating guides 1441-3 are illustrated as being formed in ring 136 and actuating cams 1041-3 are illustrated as being disposed on arms 321-3, one of ordinary skill in the art will understand that this arrangement may be reversed (i.e., actuating guides 1441-3 may be formed in arms 321-3, and actuating cams 1041-3 may be disposed on ring 136).
With reference to FIG. 5B, in the insertion position, arm cam 1061 of arm 321 is disposed at longitudinal end 881 of arm guide 821 of arm 341; in the retaining position, arm cam 1061 is disposed at longitudinal end 881′ of arm guide 821 (arm cam 1061 shown in FIGS. 6C and 6D). In the illustrated embodiment, arm cams 1062,3 are similarly positioned in arm guides 822,3 (when in the insertion and retaining positions). Although arm guides 821-3 are illustrated as being formed in arms 341-3, respectively, and arm cams 1061-3 are illustrated as being disposed on arms 321-3, respectively, one of ordinary skill in the art will understand that this arrangement may be reversed (i.e., arm guides 821-3 may be formed in arms 321-3, and arm cams 1061 may be disposed on arm 341-3).
In the illustrated embodiment, arms 321-3 of level 36 and arms 341-3 of level 38 define openings 21, 21′ (and thus diameters 22, 22′, shown in FIGS. 1 and 2), such that a substantial portion of each arm 321-3, 341-3 contacts the container or beverage. One of ordinary skill in the art will understand, however, that in other embodiments, either plurality of arms 321-3 or plurality of arms 341-3 may contact the container and define opening 21′ (e.g., arms 321-3 may actuate movement of arms 341-3, respectively, but not contact the container). Furthermore, in the illustrated embodiment, the rotation of ring 136 actuates the movement of the arms 321-3 of level 36, respectively, and arms 321-3 correspondingly actuate movement of arms 341-3 of level 38, respectively. One of ordinary skill in the art will understand, however, that the actuation flow may be reversed (i.e., ring 136 may actuate movement of arms 341-3, and arms 341-3 may actuate movement of arms 321-3).
Furthermore, although the illustrated embodiment shows actuator mechanism 24 as being ring 40, which is in the topmost position (relative to iris 30), actuator mechanism 24 may be in the bottom-most position (relative to iris 30). For example and without limitation, actuator mechanism 24 may be receptacle 26 (or a portion thereof), and pivots 541-3, 561-3 may instead project axially downwardly from ring 40, which may be fixed relative to iris 30.
Although the illustrated embodiment generally illustrates two pairs of cams and guides for each pair of upper and lower arms (one pair associated with ring 136 and arm 321, and another pair associated with arm 321 and arm 341), one of ordinary skill in the art will understand that more pairs of cams and guides may be utilized among the various components to facilitate the opening and closing of iris 30. Furthermore, other mechanical components may be utilized (other than cams and guides) to produce the same actuation flow from an actuator mechanism 24 to a two-level iris 30. Additionally, although iris 30 is illustrated as having two levels, more levels may be used.
FIG. 10 is a simplified, partial, cross-sectional view of device 20 in the insertion position. As illustrated, arms 321-3 may travel in a plane 156 parallel to a base plane 158, which is generally horizontal, and arms 341-3 may travel in a plane 160 parallel to plane 156 (and to base plane 158). In other embodiments, arms 321-3 and arms 341-3 may travel in planes not parallel to each other or to base plane 158.
