Description

Technical Field

[0001] The present invention relates to a slide rail, and more particularly to a slide rail with a locking function. Background Art

[0002] Existing slide rails control multiple components through multiple operating parts to achieve different unlocking actions. Their parts are cumbersome, making installation difficult. In terms of operation, due to different functions, the operating positions are different, occupying more structural space and increasing weight. There are also concerns about the insufficient strength of the components. Therefore, there is still room for improvement. Summary of the Invention

[0003] One object of the present invention is to provide a slide rail that can solve at least one of the above problems.

[0004] The slide rail of the present invention is adapted to engage with a stop member. The slide rail includes a track, which includes a bottom wall extending horizontally and two side walls laterally extending from both sides of the bottom wall. The bottom wall has a first end and a second end opposite to the first end; and a locking mechanism, which includes an operating part movably disposed on the bottom wall, a locking part pivotally connected to the bottom wall and the operating part, two locking positioning parts passing through the locking part and the bottom wall, and a pivot part passing through the operating part and the locking part. The locking part has a body part, a pivot part connecting the body part and pivotally connecting to the operating part, and two locking parts connecting the body part and spaced apart from each other. The operating part has a linkage groove through which the pivot part can movably pass. The linkage groove is in an inverted V shape and has a first side end, a second side end opposite to the first side end, and a linkage tip located between the first side end and the second side end. The body part forms two pivot grooves spaced apart from each other through which the locking positioning parts can relatively movably pass; the operating part can be operated to drive the locking part to rotate between an initial position, a first unlocking position, and a second unlocking position. In the initial position, the locking parts and the corresponding side walls define a locking space adapted to engage with the stop member. The pivot part is located at the linkage tip. When the operating part is operated to move towards the first end, the operating part drives the pivot part to move to the second side end, and then drives the locking part to pivot downward with the locking positioning part closer to the first end as the center of rotation to reach the first unlocking position. When the operating part is operated to move towards the second end, the operating part drives the pivot part to move to the first side end, and then drives the locking part to pivot downward with the locking positioning part closer to the second end as the center of rotation to reach the second unlocking position.

[0005] In some embodiments, the locking parts extend towards the corresponding side walls in an inclined and facing manner. Each locking part has an inner inclined surface and an outer inclined surface opposite to the inner inclined surface.

[0006] In some embodiments, the position where the bottom wall is formed corresponds to the movable slot of the linkage slot for the pivot member to pass through. The movable slot is in an inverted V shape and has a first movable side end, a second movable side end opposite to the first movable side end, and a movable tip located between the first movable side end and the second movable side end. When the locking member is in the initial position, the pivot member is located at the movable tip. When in the first unlocking position, the pivot member moves to the first movable side end. When in the second unlocking position, the pivot member moves to the second movable side end.

[0007] In some embodiments, the locking mechanism further includes a locking elastic member. One end of the locking elastic member is disposed on the bottom wall, and the other end is connected to the pivot member.

[0008] In some embodiments, the locking mechanism further includes two operating elastic members. The operating member further has an operating body and two abutting blocks respectively formed on the upper and lower sides of the operating body. One end of each operating elastic member is disposed on the bottom wall, and the other end abuts against the corresponding abutting block.

[0009] In some embodiments, the locking mechanism further includes two retaining members fixedly disposed on the bottom wall. Each retaining member has a retaining groove for accommodating the corresponding operating elastic member.

[0010] The present invention has at least the following effects: By operating the operating member, the locking member can be driven to rotate between the initial position, the first unlocking position, and the second unlocking position. That is, only by operating a single operating member can different unlocking actions be achieved. There are relatively few parts and it is easy to install. Moreover, no matter what function is required by the operator, it is convenient to operate at the same position, saving structural space and reducing weight. In addition, the structural strength of a single component is also relatively strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0019] Refer to Figures 1 to 3 , an embodiment of the slide rail of the present invention is adapted to engage with a stopper member 20 of another slide rail (not shown in the figure). The slide rail 10 includes a track 1 and a latching mechanism 2.

[0020] The track 1 includes a horizontally extending bottom wall 11, two side walls 12 laterally extending from both sides of the bottom wall 11, a movable groove 13 formed in the bottom wall 11, and a hook 14 formed in the bottom wall 11 above the movable groove 13. The bottom wall 11 has a first end 111 and a second end 112 opposite to the first end 111. The movable groove 13 is in an inverted V shape and has a first movable side end 131, a second movable side end 132 opposite to the first movable side end 131, and a movable tip 133 located between the first movable side end 131 and the second movable side end 132.

[0021] The latching mechanism 2 includes an operating member 21 movably disposed on the bottom wall 11, a latching member 22 pivotally connected to the bottom wall 11 and the operating member 21, two latching positioning members 23 passing through the latching member 22 and the bottom wall 11, a pivot member 24 passing through the operating member 21 and the latching member 22, two operating positioning members 25 respectively passing through the operating member 21 and the bottom wall 11 and spaced apart from each other, two operating elastic members 26, two holding members 27, and a latching elastic member 28. The operating member 21 includes an operating body 211, two abutting blocks 212 respectively formed on the upper and lower sides of the operating body 211, a linkage groove 213 formed at one end of the operating body 211 facing the second end 112, and two elongated positioning grooves 214 formed on the operating body 211 and spaced apart from each other. The operating body 211 is generally in the shape of a long thin plate (sheet). The abutting blocks 212 are staggered in position above and below the operating body 211. The linkage groove 213 allows the pivot member 24 to pass through movably, and its position corresponds to the movable groove 13. The linkage groove 213 is in an inverted V shape and has a first side end 213a, a second side end 213b opposite to the first side end 213a, and a linkage tip 213c located between the first side end 213a and the second side end 213b. The operating positioning members 25 respectively pass through the positioning grooves 214 and are fixedly passed through the bottom wall 11, so that the operating member 21 can only move in the extending direction of the positioning grooves 214. The holding members 27 are respectively fixedly disposed on the bottom wall 11, and each holding member 27 has a holding groove 271 for accommodating the corresponding operating elastic member 26. One end of each operating elastic member 26 abuts against the holding member 27, and the other end abuts against the corresponding abutting block 212. It should be noted that in other embodiments, the holding members 27 can be omitted, and one end of each operating elastic member 26 can be directly fixedly disposed on the bottom wall 11, and is not limited to the form of this embodiment.

[0022] The latching member 22 has a body portion 221, a pivot portion 222 connecting the body portion 221 and pivotally connecting to the operating member 21, and two latching portions 223 connecting the body portion 221 and spaced apart from each other. The body portion 221 forms two pivot grooves 221a spaced apart from each other for the latching positioning members 23 to pass through relatively movably. The pivot member 24 passes through the pivot portion 222, the linkage groove 213, and the movable groove 13. One end of the latching elastic member 28 is disposed on the hook 14, and the other end is connected to the pivot member 24. The latching portions 223 extend obliquely towards the corresponding side wall 12 in opposite directions. Each latching portion 223 has an inner inclined surface 223a and an outer inclined surface 223b opposite to the inner inclined surface 223a. The latching portions 223 and the corresponding side wall 12 define a latching space S suitable for engaging with the stopper 20.

[0023] The operation process of the slide rail 10 of the present invention is as follows: Refer toFigure 3 and Figure 4 When another slide rail (not shown in the figure) moves relative to the slide rail 10, the stopper 20 first abuts against the outer inclined surface 223b of one of the latching portions 223, causing the latching member 22 to pivot slightly downward, and then the stopper 20 can enter the latching space S along the outer inclined surface 223b, as Figure 4 shown. Then refer to Figures 4 to 6 . The user can operate the operating member 21 to drive the latching member 22 to rotate between an initial position, a first unlocking position, and a second unlocking position. In the initial position, the latching portion 223 and the corresponding side wall 12 define a latching space S suitable for engaging with the stopper 20, and the pivoting member 24 is located at the linkage tip 213c and the movable tip 133. When the operating member 21 is pulled and moves toward the first end 111, the operating member 21 drives the pivoting member 24 to move to the second side end 213b and the first movable side end 131, thereby driving the latching member 22 to pivot downward with the latching positioning member 23 closer to the first end 111 as the center, so as to reach the first unlocking position, as Figure 5 shown. At this time, another slide rail (not shown in the figure) can be separated from the slide rail 10. When the operating member 21 is pushed and moves toward the second end 112, the operating member 21 drives the pivoting member 24 to move to the first side end 213a and the second movable side end 132, thereby driving the latching member 22 to pivot downward with the latching positioning member 23 closer to the second end 112 as the center, so as to reach the second unlocking position, as Figure 6 shown. At this time, another slide rail (not shown in the figure) and the slide rail 10 can complete the folding action.

[0024] It should be noted that the operating elastic member 26 and the latching elastic member 28 both function as a reset. When the latching member 22 is in the first unlocking position, the abutting block 212 located below compresses the corresponding operating elastic member 26, and the elastic restoring force of the operating elastic member 26 can push the operating member 21 back from the first unlocking position to the initial position. Similarly, the latching member 22 compresses the latching elastic member 28, and the elastic restoring force of the latching elastic member 28 can push the latching member 22 back from the first unlocking position to the initial position. When the latching member 22 is in the second unlocking position, the abutting block 212 located above compresses the corresponding operating elastic member 26, and the elastic restoring force of the operating elastic member 26 can push the operating member 21 back from the second unlocking position to the initial position. Similarly, the latching member 22 compresses the latching elastic member 28, and the elastic restoring force of the latching elastic member 28 can push the latching member 22 back from the second unlocking position to the initial position.

[0025] In summary, the slide rail 10 of the present invention can be operated by the operating member 21 to drive the locking member 22 to rotate between an initial position, a first unlocking position and a second unlocking position, that is, only by operating a single operating member 21 can different unlocking actions be achieved. There are relatively few parts and it is easy to install. Moreover, no matter what function is required, the operator can operate conveniently at the same position, saving structural space and reducing weight. In addition, the structural strength of a single member is also relatively strong. Therefore, the purpose of the present invention can indeed be achieved.

[0026] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
