Description

Furniture and slide rail assembly thereof

The present application is a divisional application of the invention patent application with the name of furniture and a sliding rail assembly thereof, which is filed by the applicant in 2018, 01 and 24 days and has the application number of 201810067956.1.

Technical Field

The present disclosure relates to sliding rails, and particularly to a sliding rail assembly for furniture.

Background

Generally, the slide rail assembly is quite widely used, for example, in furniture or electronic equipment rack systems. Taking furniture as an example, the sliding rail assembly comprises a fixed rail and a movable rail which can longitudinally displace relative to the fixed rail. The fixed rail is usually installed and fixed on a cabinet body, and the movable rail can be used for bearing a drawer, so that the drawer can move relative to the cabinet body through the movable rail.

However, sometimes, because of different requirements, such as matching the length of the cabinet to the length of the drawer in terms of installation tolerances, or the user does not want the depth position to be too deep or too shallow when the movable rail is retracted relative to the fixed rail. Based on these related needs, rail assemblies or furniture having adjustment functions have also been developed.

For example, U.S. Pat. No. 9,179,771 B2 discloses a connection device (5) for drawers, wherein the connection device (5) is capable of releasably connecting a drawer to a rail of an extension guide. The connecting device 5 is provided with an adjusting wheel (adjusting device) for adjusting the position of the drawer relative to the cabinet. This related patent is incorporated herein by reference.

However, the adjusting wheel is disposed on the connecting device 5, and it is not desirable to implement the adjusting function in this configuration depending on the market demands, so how to develop a different related product becomes a non-negligible issue.

As shown in fig. 1, a piece of furniture 20 according to an embodiment of the present invention includes a first piece of furniture 22 and a second piece of furniture 24. Here, the first furniture member 22 is taken as a cabinet, and the second furniture member 24 is taken as a drawer, although fig. 1 shows three drawers, however, the number is not limited in implementation.

As shown in fig. 2, the furniture 20 further comprises a rail assembly 21 having a first rail 26 and a second rail 28 longitudinally displaceable relative to the first rail 26, and preferably a third rail 30 movably mounted between the first rail 26 and the second rail 28 for extending the longitudinal displacement of the second rail 28 relative to the first rail 26. The second furniture member 24 includes a bottom wall 32, a side wall 34, a front panel 36 and a rear wall 38 that together define a drawer space. Wherein the second rail 28 is configured to carry the second furniture member 24. Here, the side wall 34 of the second furniture member 24 may be pre-installed on the second rail 28, and the front panel 36 of the second furniture member 24 may be detachably fixed to the front end portion of the side wall 34; on the other hand, the first rail 26 is fixed to the first furniture piece 22 described above. According to this configuration, the second furniture member 24 is displaceable relative to the first rail 26 (or the first furniture member 22 described above) via the second rail 28. Since this part is a technical scope that can be understood by a person skilled in the art, it is not described in detail herein for the sake of brevity.

As shown in fig. 3 and 4, the sliding track assembly 21 includes a blocking structure 40 disposed on one of the first rail 26 and the second rail 28 (or the blocking structure 40 is disposed on one of the first rail 26 and the first furniture piece 22). Here, the blocking structure 40 is exemplified as being disposed on the first rail 26, but is not limited in implementation. Preferably, the blocking structure 40 is fixed to the first rail 26, and the blocking structure 40 includes a base 42 and a blocking member 44. The base 42 has a connecting portion 42a, a standing portion 42b, a first bending portion 42c and a second bending portion 42d. Wherein the connecting portion 42a is fixedly connected to the bottom of the first rail 26 and laterally extends a predetermined distance from the bottom of the first rail 26; the vertical portion 42b is substantially vertically connected to the connecting portion 42a, and the first bending portion 42c is connected between the vertical portion 42b and the second bending portion 42d. Wherein the standing portion 42b, the first bending portion 42c and the second bending portion 42d define a chamber 46; the blocking member 44 is received in the chamber 46. Here, the blocking member 44 is fastened to the base 42 by a snap-fit manner, and the blocking member 44 is partially exposed outside the chamber 46.

Further, the sliding rail assembly 21 includes an adjusting device 48 disposed on the other of the first rail 26 and the second rail 28 (or the adjusting device 48 is disposed on the other of the second rail 28 and the second furniture member 24). Here, the adjusting device 48 is exemplified by, but not limited to, a side edge between a front portion 28a and a rear portion 28b of the second rail 28. The adjustment device 48 includes an adjustment member 50, a work piece 52, and a mounting bracket 54.

As shown in fig. 4, 5 and 6, the fixing frame 54 includes a first wall 56 and a second wall 58. Preferably, an intermediate wall 60 is located between the first wall 56 and the second wall 58. The first wall 56 and the second wall 58 are substantially perpendicular to the intermediate wall 60. Wherein the middle wall 60 is fixed to the other of the first rail 26 and the second rail 28, for example, the middle wall 60 may be fixed to the second rail 28 by screwing, riveting, clamping or welding (as shown in fig. 4). Alternatively, as shown in fig. 4a, in other embodiments, the first wall 56 and the second wall 58 of the fixing frame may be integrated with the other of the first rail 26 and the second rail 28, for example, the second rail 28 is located at a side of the second rail 28, which is not limited in implementation.

As shown in fig. 5 and 6, a space S is defined between the first wall 56 and the second wall 58 of the fixing frame 54, and the adjusting member 50 is accommodated in the space S. The adjusting member 50 has a first side L1 and a second side L2 opposite to each other and respectively corresponding to the first wall 56 and the second wall 58, so that the adjusting member 50 can be limited between the first wall 56 and the second wall 58, and the first side L1 has a shaft portion 62 pivotally connected to the first wall 56.

The work piece 52 includes a threaded portion 52a, a contact portion 52b, and an intermediate portion 52c, the intermediate portion 52c being connected between the threaded portion 52a and the contact portion 52 b. The middle portion 52c and the threaded portion 52a of the working member 52 can penetrate from a hole H of the second wall 58 and the second side L2 of the adjusting member 50 into the interior of the adjusting member 50, and the threaded portion 52a is threaded to a corresponding threaded portion 50a of the interior of the adjusting member 50. Wherein the contact portion 52b of the workpiece 52 is located outside the space S of the fixing frame 54. It will be appreciated that the adjustment member 50 and the working member 52 are threaded relative to each other. Wherein the working member 52 is at an initial position P0 when the adjusting member 50 has not been rotated.

As shown in fig. 7 and 8, the adjustment device 48 is configured to convert a rotational motion of the adjustment member 50 into a displacement of the working member 52 relative to a linear direction X of the fixing frame 54. For example, when the adjusting member 50 is rotated in a first rotational direction R1, the working member 52 is linearly displaced to a first position P1 in a first direction D1 relative to the fixing frame 54 in response to the rotational adjustment of the adjusting member 50. It should be noted that the hole H of the second wall 58 is provided for the middle portion 52c of the workpiece 52 to pass therethrough, and the contour of the middle portion 52c is substantially the same as the shape of the hole H. Preferably, the hole H is a non-circular hole. In other words, the hole H and the middle portion 52c are in a matching configuration with a non-circular profile.

Alternatively, as shown in fig. 9 and 10, when the adjusting member 50 is rotated in a second rotation direction R2, the working member 52 is linearly displaced to a second position P2 in a second direction D2 relative to the fixing frame 54 in response to the rotational adjustment of the adjusting member 50. The second rotation direction R2 is opposite to the first rotation direction R1, and the second direction D2 is opposite to the first direction D1.

As shown in fig. 11, the adjusting member 50 has not been rotated, and the working member 52 is at the initial position P0; in this state, when the second rail 28 (or the second furniture member 24) is folded (e.g., fully folded) with respect to the first rail 26 (or the first furniture member 22), the working member 52 is at the initial position P0 against the blocking structure 40, such as the contact portion 52b of the working member 52 against the blocking member 44 of the blocking structure 40, so that the second rail 28 is at an initial longitudinal position Y0 with respect to the first rail 26, where an initial distance K0 is defined between the front portion 28a of the second rail 28 and the blocking structure 40, and an initial longitudinal distance Z0 is defined between the front panel 36 of the second furniture member 24 and the blocking structure 40.

As shown in fig. 12, the adjusting member 50 can be rotated in the first rotation direction R1 to bring the working member 52 to the first position P1; in this state, when the second rail 28 (or the second furniture member 24) is folded (e.g., fully folded) with respect to the first rail 26 (or the first furniture member 22), the working member 52 is in the first position P1 and can abut against the blocking structure 40, e.g., the contact portion 52b of the working member 52 can abut against the blocking member 44 of the blocking structure 40, so that the second rail 28 is in a first longitudinal position Y1 with respect to the first rail 26, where a first distance K1 is defined between the front portion 28a of the second rail 28 and the blocking structure 40, and a first longitudinal distance Z1 is defined between the front panel 36 of the second furniture member 24 and the blocking structure 40.

As shown in fig. 13, the adjusting member 50 can be rotated in the second rotation direction R2 to bring the working member 52 to the second position P2; in this state, when the second rail 28 (or the second furniture member 24) is folded (e.g., fully folded) with respect to the first rail 26 (or the first furniture member 22), the working member 52 is in the second position P2 and can abut against the blocking structure 40, e.g., the contact portion 52b of the working member 52 can abut against the blocking member 44 of the blocking structure 40, so that the second rail 28 is in a second longitudinal position Y2 with respect to the first rail 26, and a second distance K2 is defined between the front portion 28a of the second rail 28 and the blocking structure 40, and a second longitudinal distance Z2 is defined between the front panel 36 of the second furniture member 24 and the blocking structure 40. Wherein the second longitudinal position Y2 is different from the first longitudinal position Y1, the second distance K2 is different from the first distance K2, and the second longitudinal distance Z2 is different from the first longitudinal distance Z1.

From the above description, it can be seen that the enhancement effect and advantage of the present invention are:

a. by adjusting the adjustment member 50, the position of the working member 52 in the linear direction X (which is substantially the same as the length direction of the second rail 28 or the displacement direction of the second rail 28 relative to the first rail 26) can be changed, and the working member 52 can be abutted against the blocking structure 40, so that the second rail 28 (or the second furniture member 24) can be positioned at different longitudinal depth positions (e.g., the initial longitudinal position Y0, the first longitudinal position Y1, or the second longitudinal position Y2) when being retracted (e.g., fully retracted) relative to the first rail 26 (or the first furniture member 22), so as to match or fit the requirements of the first furniture member 22 and the second furniture member 24 in terms of longitudinal depth (or length).

b. By disposing the adjusting device 48 and the blocking structure 40 on a movable object and a fixed object of the furniture respectively, the movable object (e.g. the second rail 28 or the second furniture piece 24) can be located at different longitudinal depth positions when being folded relative to the fixed object (e.g. the first rail 26 or the first furniture piece 22), so that the structural configuration of the embodiment of the invention is simplified compared with the prior art, so as to meet specific operation requirements in the market.

While the invention has been described with reference to the present specific embodiments, it will be appreciated by those skilled in the art that the above embodiments are for illustration only, and that various equivalent changes and modifications may be made without departing from the spirit of the invention, and therefore, all changes and modifications to the above embodiments are intended to be within the scope of the claims of the present application as long as they come within the true spirit of the invention.
