## Background
BACKGROUND
1. Field of the Invention
The instant disclosure relates to an assembly having a liftable lid and a movable hinge module thereof; in particular, to a movable hinge module disposed between a lid and an object for pivotally connecting the lid that is capable of rotating with respect to the object over an opening of the object in an open and close manner.
2. Description of Related Art
Many products have a lid that can be opened in respect to a case. A hinge mechanism is disposed between the lid and the case. A conventional hinge mechanism is shown in FIGS. 1 and 2. A shaft 81 of a lid 8 is arranged underneath the bottom face of the lid 8, such that the shaft is not exposed to the exterior. However, to allow adequate space for the lid 8 to swing upward when opening, a gap is required between the lid 8 and an opening of a case 10, such that the lid 8 can flip 90° upwardly as shown in FIG. 2. This way produces an apparent gap L which affects the aesthetic of the product.
BRIEF SUMMARY OF THE INVENTION
The instant disclosure provides an assembly having a liftable lid to reduce its aesthetic effect caused by a hinge module. The hinge module is hidden underneath the lid when the assembly is at a close state. Because the hinge module is movable, when the lid opens, the hinge module is raised to create more space for the lid to openly rotate.
According to one exemplary embodiment of the instant disclosure, the assembly having a liftable lid includes an object having an opening, a lid rotatably arranged upon the opening in an open and close manner and a hinge module. The hinge module includes at least one shaft connected to a bottom face of the lid, a base and at least a latch. The base is selectively at an inner side of a surface of the object or an outer side of the surface of the object by a force. The shaft is rotatably connected to the base, and the shaft and the base collectively define a rotating axis. The rotating axis is movably arranged between the inner side of the surface of the object that is a close position and the outer side of the surface of the object that is an open position. The latch fastens the lid at the opening. When the rotating axis is at the close position, the lid closes upon the opening as a close state. When the rotating axis moves away from the close position, the lid rotates along the rotating axis and moves away from the opening to an open state. The rotating axis correspondingly moves to the open position.
In addition, the instant disclosure further provides a movable hinge module that is pivotally connected to the object over the opening so as to be able to rotate for opening or closing the lid. Meanwhile, when the lid closes upon the opening, the overall aesthetic is not compromised.
According to another embodiment of the instant disclosure, a movable hinge module that is pivotally connected to the object over the opening for opening or closing the lid in rotation is provided. The hinge module includes at least one shaft connected to a bottom face of the lid, a base and at least a latch. The base is selectively at an inner side of a surface of the object or an outer side of the surface of the object by a force. The shaft is rotatably connected to the base, and the shaft and the base collectively define a rotating axis. The rotating axis is movably arranged between the inner side of the surface of the object that is a close position and the outer side of the surface of the object that is an open position. The latch fastens the lid at the opening. When the rotating axis is at the close position, the lid closes upon the opening as a close state. When the rotating axis moves away from the close position, the lid rotates along the rotating axis and moves away from the opening to an open state and the rotating axis correspondingly moves to the open position.
The hinge module is movable to allow pivotal connection between the lid and the object, such that the lid can arrange upon, in other words close or open upon, the opening of the object in rotation. When the lid closes upon the opening, the lid sinks below the surface of the object, such that the hinge module does not affect the object aesthetic. When the lid opens, the hinge module shifts above the object surface to allow more rotation space.
In order to further understand the instant disclosure, the following embodiments are provided along with illustrations to facilitate the appreciation of the instant disclosure; however, the appended drawings are merely provided for reference and illustration, without any intention to be used for limiting the scope of the instant disclosure.

DETAILED DESCRIPTION OF THE INVENTION
The aforementioned illustrations and following detailed descriptions are exemplary for the purpose of further explaining the scope of the instant disclosure. Other objectives and advantages related to the instant disclosure will be illustrated in the subsequent descriptions and appended drawings.
In the following description, when it comes to the number or the like, unless specifically described, the instant disclosure is not limited to the number mentioned. Throughout the present specification, expression of relative position such as “top”, “bottom”, “left”, “right”, “front”, “rear” etc, are used solely for convenience and clarity as oriented in the drawings. They are in no way intended to be limited as to the orientation of use of the instant disclosure described.
First Embodiment
Please refer to FIGS. 3 and 4 showing perspective views of an assembly having a liftable lid from different angles. The assembly having the liftable lid includes an object 9, a lid 7 and a movable hinge module 3 disposed on the object 9 to allow the lid 7 to rotatably open or close. The object 9 includes an opening 90. The object 9 of the instant disclosure is suitable to any structure having the lid 7, for example, a door plate, a panel, a case, a wall or the like. The object 9 and the lid 7 may be configured to any geometrical configuration and the instant disclosure is not limited to the instant embodiment. The lid 7 is disposed on the object 9 over the opening 90 in a rotatable opening-closing manner. A gap g between the lid 7 and the object 9 does not expose the hinge module 3, and the gap g is not too large to affect the aesthetic. Preferably, when the lid 7 is at a close state, the circumferential region of a surface of the lid 7 is flushed with a surface of the object 9. When the lid 7 is at an open state, a portion of the lid 7 is positioned above the surface of the object 9.
The hinge module 3 of the instant embodiment includes a pair of shafts 31 connected to a bottom face of the lid 7 and a base 33. The base 33 is movable in relation to the surface of the object 9. By a force, the base 33 may be positioned to the inner side of the surface of the object 9 or the outer side of the surface of the object 9. The force may come from an external force from a user, gravity, elasticity or a kinetic component. According to the drawing of the instant embodiment, the base 33 may shift upwardly or downwardly in relation to the object 9. When the hinge module 3 is employed in a vertical object, the base 33 may shift laterally right or left into and out of the inner side of the object 9. The pair of shafts 31 is rotatably connected to the base 33, and the shafts 31 and the base 33 collectively define a rotating axis X. In other words, the pair of shafts 31 can rotate along the rotating axis X in relation to the base 33. The hinge module may be, for example, a conventional hinge, a torsion hinge, an elastic hinge, a stepping hinge or the like and the instant disclosure is not limited thereto.
It should be noted that the rotating axis X is movably arranged between a close position at the inner side of the surface of the object 9 (as shown in FIG. 5) and an open position at the outer side of the surface of the object 9 (as shown in FIG. 7) and moves thereby. When the rotating axis X is at the close position, the lid 7 closes upon the opening 90 of the object 9 to be at the close state. When the rotating axis X moves away from the close position, the lid 7 is allowed to turn about the rotating axis X and move away from the opening 90 to be at the open state. The rotating axis X correspondingly reaches the open position.
The instant embodiment may further include a pair of latches 35, 37 to secure the lid 7 over the opening 90. However, the latches 35, 37 may be omitted. For example, in the instant embodiment, gravity leads the lid 7 to be in the constant close state. When the lid 7 is to be lifted, a user exerts a force to pull out the lid 7.
Please refer to FIG. 5 (an elastic element 38 is not shown in this figure), in which the lid 7 is in the close state. When the rotating axis X is at the close position, the lid 7 closes upon the opening 90 of the object 9. Preferably, the surface 71 of the lid 7 is co-planar with the surface 91 of the object 9, and the instant disclosure is not limited thereto.
Please refer to FIG. 6. In the instant embodiment, a push-push latch is exemplified to explain the action of opening. In the process of opening, a force is first exerted to open the lid 7. The lid 7 then moves away from the surface 91 of the object 9 by the push of the elastic element 38.
Please refer to FIG. 7, in which the lid 7 is in the open state. In the instant embodiment, as the lid 7 moves away from the surface 91 of the object 9, a portion of the hinge module 3 (the latch boxes 350, 370 of the latches 35, 37 do not move) moves outwardly away from the outer side of the surface of the object 9. Also, the lid 7 turns about the rotating axis X and away from the opening 90 to an erected open state. However, the angle between the surface 71 of the lid 7 and the surface 91 of the object 9 is not limited to be normal as shown in FIG. 7 in accordance with the instant embodiment. Different angles such as an obtuse angle, acute angle, or 0 degree angle may also be possible as an open state, and FIG. 7 does not intend to limit the angle.
As shown in FIG. 7, the lid 7 turns about the rotating axis X outwardly for approximately 90° to the open state. In the instant embodiment, when the lid 7 is at open state, a side face 73 of the lid 7 only abuts the surface 91 of the object 9. However, the instant disclosure is not limited thereto. The above description is merely an embodiment. The side face 73 can help positioning the lid 7. The contacting area between the side face 73 of the lid 7 and the surface 91 of the object 9 may not be planar and may be in other configurations.
This arrangement in the instant disclosure provides the following benefit: the rotating axis X shifts from the inner side of the surface of the object 9 to the outer side of the surface of the object 9, such that the lid 7 turns outwardly about the rotating axis X formed by the hinge module 3 in order to open. Therefore, unlike the conventional hinge mechanism, the oversized gap L is not formed between the object and the lid. In addition, the hinge module 3 of the instant disclosure is hidden in the inner side of the lid when the lid 7 is closing and does not expose itself so as to maintain the overall aesthetic.
As shown in FIGS. 4 and 8, preferably, the instant embodiment also includes a pair of elastic elements 38 disposed on two sides of the base 33. The elastic elements 38 allow easier operation when opening the lid 7. One end of the elastic element 38 (as shown in FIG. 4, i.e., the bottom end of the elastic element 38) is engaged to a fixed structure (not shown), for example, the extension of the object 9 or other members below the object 9 is capable of fixing the elastic element 38. The other end of the elastic element 38 (as shown in FIG. 4, i.e., the top end of the elastic element 38) abuts against the base 33 so as to allow the rotating axis X to shift from the close position toward the open position. When the lid 7 closes upon the object 9, corresponding to the rotating axis X at the close position, the elastic elements 38 are compressed to store potential energy. When the latches 35, 37 are unlocked, the elastic elements 38 push the lid 7 to the outer side of the surface of the object by the stored potential energy to facilitate the user to open the lid 7. The elastic element 38 may exert a force that is capable of pushing the lid 7 up to the open state.
In the instant embodiment, the elastic element 38 is a compression spring and is not limited thereto. For example, the elastic element 38 may be a torsion spring or a V-like spring sheet. The torsion spring or an elastic sheet is compressed when the lid is at the close state, and a stored potential energy is provided to push the base 33 from one end of the elastic element. Therefore, the elastic element 38 may provide the force that drives the lid 7 to turn and automatically reach to the open state of the lid 7 after the latches 35, 27 are unlocked. The elastic element 38 may be other kinetic elements. Alternatively, the lid 7 can be lifted by a more efficient way. Specifically, after the lid 7 is unlocked, the user lifts the lid 7 for opening. In this way, the elastic element 38 can be omitted.
Please again refer to FIG. 4. The detail structure of the instant embodiment is elaborated hereinafter. The base 33 includes a main body 331. The top end of the main body 331 is formed with a pair of shaft depression 334 facing the bottom face of the lid 7. Two sides of the main body 331 are formed with an abutting portion 333 respectively. Each of abutting portions 333 has an elastic element 38. Each abutting portion 333 has a downwardly protruding pillar 335 for receiving the compression spring (elastic element 38) sleeved thereon. The pair of shafts 31 are respectively rotatably disposed in the pair of shaft depressions 334, and therefore the shafts 31 and the base 33 collectively define the rotating axis X.
The shaft 31 may be pivoted with respect to the shaft depression 334 by a post or by a pivot (not shown), and the instant disclosure is not limited thereto.
Please refer to FIG. 8. In the instant embodiment, the latch 35 is positioned close to a pivot end of the lid 7 and the latch 37 is positioned close to a lock end of the lid 7 opposite to the pivot end. The pair of the latches 35, 37 is respectively disposed at a bottom face of the base 33 and the bottom face of the lid 7. The latches 35, 37 may be fixed to the inner side of the object 9 or to other structures (not shown) capable of fixing the latches 35, 37. The latch may be a push-push latch. For example, the latch 35 includes a hook 351 connected to the base 33 and a latch box 350 fixedly disposed below the object 9. The hook 351 engages to or disengages from the latch box 350 by a single push. In the instant embodiment, the main body 331 is formed in the middle with a depression 3310 to accommodate the hook 351. When the hook 351 engages to the latch box 350, a portion of the latch box 350 is received in the depression 3310. The latch 37 includes a hook 371 connected to the bottom face of the lid 7 and a latch box 370 fixedly disposed below the object 9.
In the instant embodiment, the pair of latches 35, 37 being push-push latches are used to achieve the advantage described herein: when the user presses the middle region of the lid 7, the two push-push latches (i.e., latches 35, 37) can be unlocked simultaneously, and the lid 7 is released. In addition, the push-push latch itself has an elastic force, such that when the lid 7 is released from the latches 35, 37, the elastic force of the push-push latch is provided to push the lid 7 open in an outward rotation.
However, the latch of the instant disclosure is not limited to the above-mentioned push-push latch, and the latch may be, for example, a tenon latch, a bolt latch (sliding or rotating), a release button, a trigger switch or the like.
Second Embodiment
Please refer to FIGS. 9 and 10 showing an exploded perspective view and an assembled perspective view in accordance with another embodiment of the assembly having a liftable lid. In the instant embodiment, another approach is implemented to displace the hinge module. FIG. 9 shows that the base 33′ of the instant embodiment has a pair of limiting portions 339 extending downwardly from the main body 331. The limiting portion 339 is formed with a limiting slot 3390 at a center portion of the limiting portion 339. The bottom face of the object 9 further includes a pair of limiting blocks 39 that may extend from the bottom face of the object 9 or may be provided by other structures. Each of the limiting blocks 39 has a limiting post 391. The limiting post 391 is movably disposed in the limiting slot 3390. When the limiting post 391 moves to the first end 3391 of the limiting slot 3390, the rotating axis X is positioned to the open position. When the limiting post 391 moves to the second end 3392 of the limiting slot 3390, the rotating axis X is positioned to the close position.
However, the displacement of the hinge module is not limited to the abovementioned embodiment. For example, the bottom face of the main body 331 may be extended to form a limiting arm (not shown) close to the latch box 350. The limiting arm extends downwardly along the side of the latch box 350 and engages to the bottom of the latch box 350 to limit the movement of the hinge module.
In summary, the instant disclosure provides a movable hinge module, such that the lid 7 is pivotally connected to the object 9 over the opening 90 in a rotatably open or close manner. When the lid 7 closes, the hinge module 3 enters underneath the surface 91 of the object 9 so as to reduce any negative effect on the overall appearance caused by the hinge module. When the lid 7 opens, the hinge module 3 is pushed out to the surface 91 of the object 9 by a force so as to provide the lid 7 with more rotation space. The movable hinge module of the instant disclosure can be adapted to any kinds of rotation assembly for opening and closing. The advantages are that the space is more efficiently used and the overall product aesthetics is not affected. The structure of the instant disclosure is simple, and the assembly process is simplified. Unlike the conventional technique, the lid is fully open and the product aesthetic with the lid is not compromised.
It should also be noticed that the number of the shaft of the hinge module is not limited to a pair. The number of shafts may be at least one, or more than two. The at least one shaft is rotatably connected to the base, and the shaft and the base collectively define a rotating axis X. Likewise, the number of the latch is not limited to a pair. The latch may be at least one lock to maintain the lid to the close state. A single latch may be disposed close to the lock end of the lid 7 and extending to the pivot end of the lid. By operating the latch disposed at the lock end of the lid, both the lock end and the pivot end of the lid are unlocked. Another embodiment of a single latch 35 positioned close to the pivot end of the lid 7 is illustrated in FIG. 11 to FIG. 13. Similar to the description of FIG. 5 to FIG. 7, the lid 7 is in the close state in FIG. 11, and a force is first exerted to open the lid 7 in FIG. 12, and the lid 7 then moves away from the surface 91 of the object 9 by the push of the elastic element 38. Referring to FIG. 13, the lid 7 moves away from the surface 91 of the object 9, and turns about the rotating axis X and away from the opening 90 to an erected open state.
The descriptions illustrated supra set forth simply the preferred embodiments of the instant disclosure; however, the characteristics of the instant disclosure are by no means restricted thereto. All changes, alternations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the instant disclosure delineated by the following claims.
