Description

The present invention relates to a slide rail assembly, and more particularly, to a slide rail assembly having a design of a buffer stop function and capable of buffering a stop that can reduce impact force and sound generated when the slide rail is pulled out to a fully open state.

In general, in a slide rail used for a drawer or the like, a typical structure includes a two-part or three-part rail part, and slides by one or two sets of balls that are fitted and installed between tracks on each rail part. To do. Also, although the slide rail is installed in a drawer or the like, it may need to be removed, so many of this type of slide rail have a removable function. That is, by design, whether it is two or three nodes, in the structure of the rail component, the movable rail component connected to the knot or similar node is removable.

In the technical means of making the slide rail removable, the removable movable rail part often places a limiting part. For the fixed rail parts connected to the shelf main body or the frame frame, a support base is provided at the open end (front end) where the movable rail parts are drawn out and in contact with the limiting parts. Alternatively, when the three-bar slide rail structure is used, a separate extended rail part is connected between the fixed rail part and the movable rail part in a movable manner. A support base is installed at the front end of the extended rail parts. With this type of restriction parts, it can be prevented from coming off when the movable rail parts are fully stretched, or the engagement between the restriction parts and the support base can be temporarily released by moving the support base. The rail parts can be pulled out and removed.

However, the technical means to contact and hold the support base by the above-mentioned restriction parts is that the noise resistance to the slide rail is provided if there is no buffering action between the movable rail part, the restriction part, the support base, and the fixed rail part (or extension rail part). And adversely affects the texture of the operation. The present invention has been made in view of the drawbacks of noise and operational texture of conventional slide rails.

As shown in FIGS. 1 and 2, the slide rail assembly according to the first embodiment of the present invention includes a first rail 10, a second rail 12, a slide ball tank 14, and a support base 16.

The second rail 12 is connected to the first rail 10 in a slide shape. The slide ball tank 14 is installed between the first rail 10 and the second rail 12, and assists the slide of the second rail 12 relative to the first rail 10. The support base 16 is installed at the front end of the first rail 10 and supports the second rail 12 at the end position. Moreover, when the second rail 12 is pulled out by this, a stopping action is provided, and the second rail 12 defines a longitudinal direction L along the sliding direction of the length of the first rail 10.

As shown in FIG. 3, the first rail 10 includes a first wall 18, a second wall 20 facing the first wall 18, and a side wall 22 connected to the first wall 18 and the second wall 20. The side wall 22, the first wall 18, and the second wall 20 jointly define a channel 24, and the first rail 10 includes an open end 26 located in front of the channel 24. The open end 26 includes a contact stop 28 and an installation hole 30 located on the side wall 22. The installation holes 30 are a pair or a single, and are illustrated as a pair.

The second rail 12 is movably connected to the channel 24 of the first rail 10, and includes an upper wall 32, a lower wall 34 facing the lower wall 32, and an intermediate wall 36 connected to the upper wall 32 and the lower wall 34. . Furthermore, a limiting component 38 is provided and installed on the inner wall 36 of the second rail 12.

The limiting component 38 includes a lock portion 40, a resilient leg 42 that contacts the lower wall 34 of the second rail 12, and an operation rod 44 that is positioned between the lock portion 40 and the resilient leg 42. By moving the operating rod 44, the lock portion 40 is moved and unlocked with respect to the support base 16, and thus the second rail 12 can be detached from the first rail 10.

As shown in FIG. 3, the slide ball tank 14 is movably installed on the first rail 10 and includes a slide frame 46 and a plurality of balls 48 installed on the slide frame 46.

As shown in FIG. 4, the support base 16 is movably installed in the channel 24 of the first rail 10, and corresponds to the open end 26 and faces the first support portion 50 and the first support portion 50. A second support part 52, a side part 54 connected between the first support part 50 and the second support part 52, and a stop block 56 connected to the side part 54 are provided. The first support part 50 and the second support part 52 are held by the first wall 18 and the second wall 20 of the first rail 10, and between the side part 54 and the contact stop part 28 of the first rail 10. Installs at least one installation portion 60 corresponding to the buffer 58 and the installation hole 30 of the first rail 10. Preferably, the length of the installation hole 30 in the vertical direction is longer than the length of the installation portion 60 in the vertical direction. Preferably, the shock absorber 58 has an elongated shape that is continuous with the side portion 54 and has at least one curved portion, and the contact stop 28 of the first rail 10 forms a receiving hole 62, whereby the curved portion Is housed in the housing hole 62 and pressed against the contact stop 28.

FIG. 5 shows a state in which the second rail 12 is completely pulled out with respect to the first rail 10. At this time, the limiting component 38 moves according to the second rail 12. When the restricting part 38 reaches the support base 16, the locking part 40 of the restricting part 38 corresponds to the stop block 56 of the support base 16 and stops when it comes into contact. Thus, even if the second rail 12 is pulled out, it has a stopping action and does not leave.

Further, as shown in FIG. 5, even if the stop block 56 of the support base 16 collides with the lock portion 40 of the restricting part 38 with a relatively large force, the impact force and the generated sound can be reduced. As shown in FIGS. 6 and 7, the installation part 60 of the support base 16 is movable in the installation hole 30 of the first rail 10 and is not engaged and fixed. Moves within the limits in the installation hole 30, and the side portion 54 approaches the contact stop portion 28 of the first rail 10, so that the shock absorber 58 moves to the contact stop portion 28 of the first rail 10. This is because the buffer body 58 is pressed and elastically deformed by contact. Thus, the impact force and the generated sound can be reduced.

In the arrangement form of the second embodiment of the present invention shown in FIG. 8, the support base 200 includes a long tank 202. The first rail 204 includes a fixing hole 206, and the fixing pin 208 passes through the long tank 202 and is inserted into the fixing hole 206 and fixed. Moreover, the length of the long tank 202 in the vertical direction is longer than the diameter of the pin body 210 of the fixing pin 208 that passes through the long tank 202. Accordingly, the support base 200 moves the long tank 202 within the limit relative to the first rail 204.

9 and 10, the shock absorber 302 of the support base 300 is in a block shape and includes convex grains 304, and the contact stop portion 308 of the first rail 306 includes: It presents a hole into which the convex grain 304 is inserted. In the corresponding hole, the concave tank 310 is installed and the buffer 302 is accommodated. Moreover, the local portion of the buffer body 302 enters the installation hole 312 of the first rail 306 and contacts and presses the installation portion 314 of the support base 300. Thereby, the buffer 302 can be utilized and the buffer effect which is compressed and elastically deformed can be exhibited.

In the arrangement form of the fourth embodiment of the present invention shown in FIG. 11, the shock absorber 402 of the support base 400 employs a spring component, and the storage hole 408 is formed in the contact stop portion 406 of the first rail 404. Then, the spring component is put into the storage hole 408 and is brought into contact with and pressed against the contact stop portion 406. Thereby, the spring-type buffer body 402 can be used to exhibit a buffering effect of elastic compression.
