Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bicycle hooks, and particularly to a hook assembly. Background Art
[0002] In the prior art, ceiling-mounted bicycle hooks are mainly fixed types, that is, the bicycle hooks are fixed on the ceiling in a non-movable manner by means of screws or the like. After the bicycle hook is fixed on the ceiling, the bicycle is lifted by a pulley or directly lifted and hung. Since the bicycle bracket is installed on the ceiling in a fixed manner, a large amount of space will be wasted to a great extent. Therefore, for hanging multiple bicycles of different models, the space utilization rate of the fixed ceiling-mounted bicycle hooks is relatively low. For example, the distance between the fixed ceiling-mounted bicycle hooks remains unchanged. When the shape of the bicycle becomes smaller, a part of the space is wasted. Summary of the Utility Model

[0006] Further, the hook mechanism further includes an elastic member disposed between the hook member and the mounting member, and the elastic member is used to provide a driving force to the hook member to make the hook member drive the locking member to maintain the locking position in contact with the track seat.
[0007] Further, the hook mechanism further includes: a linkage member having a first end and a second end disposed opposite to each other. The linkage member is pivotally connected to the mounting member, the first end is connected to the hook member, the second end is connected to the locking member, and the pivot point between the linkage member and the mounting member is located between the first end and the second end; one end of the elastic member abuts against the mounting member, and the other end of the elastic member abuts against the linkage member to provide an elastic locking force for the linkage member to keep the locking member in the locking position.
[0008] Furthermore, the elastic component is a torsion spring, and the hook mechanism also includes a first pivot shaft for pivotally connecting the linkage component and the mounting component. A limiting groove is provided on the mounting component, and the torsion spring is wound around the first pivot shaft.

[0009] Furthermore, a limiting portion is provided on the mounting member, and the limiting portion extends around a pivot point between the linkage member and the mounting member, and the limiting portion is used to limit the swing stroke of the second end.
[0010] Furthermore, the limiting portion is an arc-shaped groove, and the hook mechanism further includes a second pivot shaft for connecting the second end and the locking member, and the second pivot shaft is in sliding engagement with the arc-shaped groove.

[0014] Furthermore, the hook member has a hook bottom and a hook end vertex, the contact point between the bicycle wheel and the hook member is the hook bottom, and the hook end vertex is the highest point of the end of the hook member. When the locking member is in the locked position, the angle between the line connecting the hook bottom and the hook end vertex and the horizontal is a, 0°≤a≤20°; when the locking member is in the unlocked position, the angle between the line connecting the hook bottom and the hook end vertex and the horizontal is b, b>a.

Detailed implementation manners
[0031] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present invention in detail with reference to the drawings and in combination with the embodiments.
[0032] As Figures 1 to 12 shown, an embodiment of the present invention provides a hook assembly. The hook assembly includes: a track seat 10 configured to be installed on a foundation to be installed; a hook mechanism 20 movably disposed on the track seat 10; the hook mechanism 20 includes a mounting member 21, a locking member 22 and a hook member 23, the locking member 22 is movably disposed on the mounting member 21, the hook member 23 is rotatably disposed on the mounting member 21, the hook member 23 is linked with the locking member 22, and by rotating the hook member 23, the locking member 22 can be disengaged from the locking position in contact with the track seat 10 to release the hook member 23, and the locking member 22 returns to the locking position in contact with the track seat 10.
[0033] In the above technical solution, when the hook assembly is in the no-load state, the locking member 22 abuts against the inner wall of the track base 10 and is in the locked position, capable of providing sufficient frictional force to keep the hook mechanism 20 stationary on the track base 10 and prevent it from moving freely, thereby ensuring the stability of the hook assembly in the unused state. When it is necessary to hook the bicycle 6, the user places the wheel or frame of the bicycle 6 on the hook member 23. As the weight of the bicycle 6 acts on the hook member 23, the hook member 23 rotates to drive the locking member 22 to move and disengage from the locked position with the track base 10, so that the hook mechanism 20 can move freely within the track base 10, facilitating the user to move the bicycle 6 along the track base 10 to a suitable position to accommodate bicycles 6 of different sizes or optimize the space layout. In this way, the distance between the hook members 23 can be dynamically adjusted according to the specific size and quantity of the bicycles 6, avoiding the problem of space waste caused by the preset distance of the fixed hooks. Especially when multiple bicycles 6 are hung, the dynamic adjustment between the hook assemblies can make more effective use of the limited storage space and improve the space utilization efficiency of the overall system.
[0034] Further, when the locking member 22 is in the locked position and the bicycle 6 is being hung, in this way, the hook assembly will not move freely due to the collision of the bicycle 6, thereby reducing the difficulty of hanging the bicycle 6.
[0035] Specifically, in the embodiment of the present invention, both ends of the track base 10 are sealed with the guide rails 4 and fixed with the self-tapping screws 15.
[0036] Specifically, in the embodiment of the present invention, the hook mechanism 20 is rotatably arranged on the track base 10, and the rotation axis of the hook mechanism 20 is parallel to the direction of gravity. In this way, by rotating the entire hook mechanism 20, 360° rotation of the hook member 23 can be achieved, thus facilitating the bicycle 6 to be hooked on the hook member 23 from different directions.
[0037] It should be noted that in the embodiment of the present invention, the locking member 22 being movably arranged on the mounting member 21 means that the locking member 22 can rotate relative to the mounting member 21 or move relative to the mounting member 21.
[0038] Specifically, in the embodiment of the present invention, the hook mechanism 20 can be one or more.
[0039] Such as Figure 8 and Figure 10 As shown, in the embodiment of the present invention, the hook mechanism 20 further includes an elastic member 25. The elastic member 25 is arranged between the hook member 23 and the mounting member 21, and the elastic member 25 is used to provide a driving force to the hook member 23, so that the hook member 23 drives the locking member 22 to maintain the locked position in contact with the track base 10.
[0040] With the above settings, when the hook assembly is in the no-load state, under the action of the elastic member 25, the locking member 22 abuts against the inner wall of the track seat 10, so that the locking member 22 is in the locked position, thereby providing sufficient friction force to keep the hook mechanism 20 stationary on the track seat 10, thus ensuring the stability of the hook assembly in the unused state.
[0041] As Figure 8 , Figure 10 and Figure 12 shown, in the embodiment of the present invention, the hook mechanism 20 further includes: a linkage member 24 having a first end and a second end disposed opposite to each other. The linkage member 24 is pivotally connected to the mounting member 21. The first end is connected to the hook member 23, and the second end is connected to the locking member 22. The pivot point between the linkage member 24 and the mounting member 21 is located between the first end and the second end; one end of the elastic member 25 abuts against the mounting member 21, and the other end of the elastic member 25 abuts against the linkage member 24 to provide an elastic locking force for the linkage member 24 to keep the locking member 22 in the locked position.
[0042] With the above settings, the elastic member 25 can provide a continuous elastic locking force for the linkage member 24, and the elastic locking force acts on the locking member 22 through the linkage member 24, so that the locking member 22 remains in close contact with the track seat 10 in the no-load state and is in the locked position. Among them, when an external force (such as the weight of the bicycle 6) acts on the hook member 23, the hook member 23 causes the linkage member 24 to overcome the elastic locking force, so that the locking member 22 disengages from the locked position, thereby allowing the hook mechanism 20 to move freely within the track seat 10, realizing the automatic release of the hook. In this way, the operation of mounting the bicycle 6 is greatly simplified, and the user can easily complete the mounting of the bicycle 6 without manually adjusting the hook position.
[0043] Specifically, in the embodiment of the present invention, the hook member 23 and the linkage member 24 are fixedly installed with a pin 11. The locking member 22 includes a support seat 222 and a friction plate 221. The support seat 222 is installed on the linkage member 24 with a second pivot shaft 27; the friction plate 221 is snapped into the support seat 222.
[0044] Preferably, in the embodiment of the present invention, the linkage member 24 is a connecting shaft.
[0045] As Figure 9 and Figure 10As shown, in the embodiment of the present utility model, the elastic member 25 is a torsion spring. The hook mechanism 20 further includes a first pivot shaft 26 for pivotally connecting the linkage member 24 and the mounting member 21. A limiting groove 211 is provided on the mounting member 21. The torsion spring is wound around the first pivot shaft 26. One end of the torsion spring is in limiting cooperation with the limiting groove 211, and the other end of the torsion spring abuts against the linkage member 24.
[0046] In the above technical solution, when the hook assembly is in the no-load state, one end of the torsion spring is in limiting cooperation with the limiting groove 211 of the mounting member 21, and the other end of the torsion spring abuts against the linkage member 24. In this way, the torsion spring can provide an elastic locking force in the natural state to keep the locking member 22 in the locking position, so that the locking member 22 remains in contact with the inner wall of the track base 10 to form frictional locking; when the hook member 23 hangs the bicycle 6, the external force is transmitted to the hook member 23 through the bicycle 6, so that the linkage member 24 rotates relative to the mounting member 21 around the first pivot shaft 26. The elastic characteristic of the torsion spring enables the linkage member 24 to respond quickly and makes the locking member 22 quickly disengage from the locked state with the track base 10, providing instant unlocking for the movement of the hook mechanism 20 on the track base 10 and ensuring the smoothness and convenience of hanging the bicycle 6.
[0047] Furthermore, the limiting groove 211 can fix one end of the torsion spring, ensuring that the torsion spring maintains a stable position during the movement of the hook mechanism 20, thereby preventing unnecessary displacement of the torsion spring during elastic contraction and release, ensuring that the torsion spring can always apply a force in a predetermined direction to the linkage member 24, and thus ensuring that the locking member 22 can accurately switch between the locking position and the release position.
[0048] Specifically, in the embodiment of the present utility model, when the locking member 22 switches from the unlocking position to the locking position, the hook member 23 can rotate around the first pivot shaft 26, and the vertex 232 of the hook end is far from the first pivot shaft 26.
[0049] As Figure 8 and Figure 9 shown, in the embodiment of the present utility model, a limiting portion 212 is provided on the mounting member 21. The limiting portion 212 extends around the pivot point between the linkage member 24 and the mounting member 21, and the limiting portion 212 is used to limit the swing stroke of the second end.
[0050] In the above technical solution, the limiting portion 212 extends around the pivot point between the linkage member 24 and the mounting member 21, which can effectively control the swing amplitude of the linkage member 24. In this way, unstable movement or excessive release of the locking member 22 caused by excessive swing stroke can be avoided, thereby ensuring the stability of the automatic locking function of the hook assembly when unloaded, and improving the reliability of the entire system; specifically, when the hook member 23 mounts the bicycle 6, the swing of the linkage member 24 is guided to a preset stroke, ensuring that the locking member 22 can be quickly and accurately switched from the locked position to the released position, thereby making the mounting of the bicycle 6 smoother, and also avoiding safety hazards caused by excessively violent unlocking actions.
[0051] like Figure 8 and Figure 9 As shown, in the embodiment of the present invention, the limiting portion 212 is an arc-shaped groove, and the hook mechanism 20 further includes a second pivot shaft 27 for connecting the second end and the locking member 22, and the second pivot shaft 27 is slidably engaged with the arc-shaped groove.
[0052] In the above technical solution, on the one hand, the arc-shaped groove serves as a limiting portion 212, which can accurately control the relative movement of the locking member 22, ensuring that the swing stroke of the locking member 22 is limited to a preset range during the contact and separation process with the rail seat 10, thereby avoiding excessive movement of the locking member 22, preventing unnecessary wear and damage, and improving the stability and reliability of the system; on the other hand, the shape design of the arc-shaped groove enables the second pivot shaft 27 to move smoothly, which can reduce friction and resistance during the movement, so that the second end of the linkage member 24 can more smoothly complete the switch from the locked position to the released position when pushing the locking member 22, thereby improving the overall operation fluency and efficiency of the hook mechanism 20.
[0053] Specifically, the second end and the locking member 22 are rotationally connected via the second pivot shaft 27 .
[0054] like Figure 7 and Figure 8 As shown, in an embodiment of the present invention, the hook mechanism 20 further includes: a mounting seat 51, the mounting member 21 is passed through the mounting seat 51; a shell 52, which is arranged on one side of the mounting seat 51, the shell 52 is located on the outer periphery of the mounting member 21, and the top of the locking member 22 passes through the side of the shell 52 facing away from the mounting seat 51.
[0055] In the above technical solution, on the one hand, the mounting seat 51 provides a stable mounting base for the mounting member 21, and the shell 52 is wrapped around the outer periphery of the mounting member 21, so that the multiple components of the hook mechanism 20 can be effectively integrated, which not only improves the compactness of the overall structure, but also optimizes the spatial layout; on the other hand, the shell 52 is located on one side of the mounting seat 51, covering the outer periphery of the mounting member 21, and can provide physical protection for key components such as the mounting member 21, the locking member 22 and the linkage member 24, reduce the impact of external collisions and dust, extend the service life of the components, and also reduce the difficulty of maintenance and cleaning; on the other hand, the top of the locking member 22 passes through the side of the shell 52 away from the mounting seat 51, so that the positioning stability and locking reliability of the locking member 22 when in contact with the rail seat 10 can be ensured.
[0056] like Figure 7 and Figure 8 As shown, in the embodiment of the present invention, the hook mechanism 20 further includes at least one rolling member 53 , and the rolling member 53 is rotatably disposed on the mounting seat 51 .
[0057] In the above technical solution, on the one hand, the setting of the rolling member 53 changes the contact mode between the hook mechanism 20 and the track seat 10 from sliding to rolling when the hook mechanism 20 moves along the track seat 10. In this way, the friction can be greatly reduced, making the movement of the hook assembly smoother and more efficient. On the other hand, since the friction between the rolling member 53 and the track seat 10 is rolling friction rather than sliding friction, wear can be significantly reduced, thereby enhancing the durability of the hook mechanism 20 and extending the service life of the entire system.
[0058] Specifically, in the embodiment of the present invention, at least part of the rolling element 53 is located on a side of the mounting seat 51 away from the locking member 22 , and the rolling element 53 is a rubber-coated roller.
[0059] like Figure 4 As shown, in the embodiment of the present invention, the mounting member 21 is rotatably mounted on the mounting seat 51 and the housing 52, with the axis of rotation of the mounting member 21 being parallel to the direction of gravity. This allows the hook member 23 to rotate 360° about the axis parallel to the direction of gravity, thereby facilitating the hooking of the bicycle 6 on the hook member 23 from various orientations.
[0060] It should be noted that when the locking member 22 is unlocked from the rail seat 10, the mounting member 21 can rotate freely around the axis parallel to the direction of gravity. When the locking member 22 is in the locked position, the rotation and movement of the mounting member 21 are suppressed.
[0061] It should be noted that if Figure 4 As shown, in the embodiment of the present invention, the axis of the rotating shaft of the mounting member 21 is A.
[0062] like Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the hook member 23 has a hook bottom 231 and a hook end vertex 232. The contact point between the wheel of the bicycle 6 and the hook member 23 is the hook bottom 231, and the hook end vertex 232 is the highest point of the end of the hook member 23. When the locking member 22 is in the locked position, the angle between the line connecting the hook bottom 231 and the hook end vertex 232 and the horizontal is a, 0°≤a≤20°. When the locking member 22 is in the unlocked position, the angle between the line connecting the hook bottom 231 and the hook end vertex 232 and the horizontal is b, b>a.
[0063] In the above technical solution, when the locking member 22 is in the locked position, the angle a between the line connecting the hook bottom 231 and the apex 232 of the hook end and the horizontal line is 0°≤a≤20°. In this way, the hook head is closer to the horizontal position, so that when the user mounts the bicycle 6, the wheel of the bicycle 6 can be easily slid into the hook member 23 without additionally lifting the bicycle 6, thereby reducing the difficulty of mounting and improving the user experience; when the locking member 22 is switched to the unlocked position, that is, the bicycle 6 has been hooked on the hook member 23, the angle b between the line connecting the hook bottom 231 and the apex 232 of the hook end and the horizontal line is, and b>a. In this way, the hook head is slightly tilted upward, which helps to lock the wheel of the bicycle 6 and prevent the bicycle 6 from shaking or accidentally falling off on the hook, thereby improving the safety and stability of mounting.
[0064] Preferably, in the embodiment of the present invention, the value of a can be 5°, 10°, or 15°.
[0065] Specifically, if Figure 4 As shown, in the embodiment of the present invention, when the bicycle wheel 6 is hooked on the hook member 23, the V-shaped hook of the hook member 23 will not cause the bicycle 6 to be unhooked; when the hand is released, the hook member 23 is subjected to the load of the bicycle 6, and the linkage member 24 rotates around the axis of the first pivot shaft 26, and the load axis B (the line connecting the axis of the first pivot shaft 26 and the apex 232 of the hook end) tends to approach the axis A; when the bicycle 6 is lifted, the hook member 23 tilts and opens around the first pivot shaft 26 under the action of the torsion spring, and the hook member 23 is separated from the wheel, and the bicycle 6 can be removed.
[0066] It should be noted that, in the locked position, the extension arm C of the hook member 23 is above the horizontal line.
[0067] Specifically, in the embodiment of the present invention, the arm assembly further includes a gasket 14 , the hook member 23 passes through the gasket 14 and the mounting seat 51 in sequence, and the housing 52 and the mounting seat 51 are fixed with self-tapping screws 15 .
[0068] It should be noted that the hook assembly of the embodiments of the present utility model can solve the problems of low utilization rate of the mounting space of the bicycle 6 and inconvenient mounting. The hook assembly can realize the functions of self-locking of the hook when it is unloaded and unlocking and moving when it is mounted, improving the space utilization rate and facilitating the user to mount and store the bicycle 6; moreover, the structure is simple and reliable, and the cost is low.
[0069] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: when the hook assembly is in the unloaded state, the locking member abuts against the inner wall of the track seat and is in the locked position, capable of providing sufficient friction force to keep the hook mechanism stationary on the track seat and prevent its free movement, thereby ensuring the stability of the hook assembly in the unused state. When it is necessary to hook the bicycle, the user places the wheel or frame of the bicycle on the hook member. With the weight of the bicycle acting on the hook member, the hook member rotates to drive the locking member to move and disengage from the locked position of the track seat, so that the hook mechanism can move freely in the track seat, facilitating the user to move the bicycle along the track seat to a suitable position to adapt to bicycles of different sizes or optimize the space layout. In this way, the distance between the hook members can be dynamically adjusted according to the specific size and quantity of the bicycles, avoiding the problem of space waste caused by the preset distance of the fixed hooks. Especially when multiple bicycles are mounted, the dynamic adjustment between the hook assemblies can more effectively utilize the limited storage space and improve the space utilization efficiency of the overall system.
[0070] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
