Description

Sliding rail mechanism

The present application is a divisional application of the application titled "slide rail mechanism" with chinese application No. 201910698795.0 and application date of 2019, 7, 31.

Technical Field

The present invention relates to a sliding rail, and more particularly to a sliding rail mechanism with a bracket.

Background

A rack system is disclosed, for example, in U.S. patent publication No. US 6,230,903B1. Wherein a first mounting bracket and a second mounting bracket are slidably attached to a first end and a second end of a rail member (outer rail), respectively.

An adjustable bracket for a slide assembly is disclosed in U.S. patent publication No. US 8,028,965B2. Wherein, a fixing seat is fixed to an outer rail, and a bracket is slidably installed in a channel of the fixing seat.

For example, U.S. patent publication No. 9,328,769B1 discloses a bracket device for a slide rail assembly, which comprises a rail member (outer rail), a first support frame, a second support frame, a third support frame, and a mounting bracket. The first support frame is fixed to the rail, and the second support frame, the third support frame and the mounting bracket are telescopically displaced relative to the first support frame. In addition, the mounting bracket may be adjusted to a first position (e.g., fig. 5 of the patent) relative to the rail, or to a second position (e.g., fig. 7 of the patent), as desired. Further, when the mounting bracket is at the first position relative to the rail, the mounting bracket can partially cover the rail and the first supporting frame; however, when the mounting bracket is in the second position relative to the rail, the mounting bracket does not cover any portion of the first support bracket, although the mounting bracket partially covers the rail.

For example, chinese patent publication No. CN 104507297B discloses a sliding rail bracket, which comprises a front bracket and a rear bracket. The front bracket is fixed to a rail member (outer rail). Wherein, the rear bracket is movably sleeved in the chute of the front bracket.

For example, chinese patent publication No. CN 205378453U discloses a reinforced sliding rail back frame structure, which comprises a rail, a fixing frame and a sliding frame. The fixing frame is fixed on the back of the rail piece, and the fixing frame is embedded in the sliding frame.

For example, chinese patent publication No. CN 205356912U discloses a sliding rail bracket, which comprises a rail member, a front bracket and a rear bracket. The front support is fixed on the rail piece and is inserted into the channel of the rear support.

Although the above related patent discloses the sliding rail and the bracket (or rack), as the market demand for the bearing capacity of the sliding rail increases, how to improve the structural strength of the sliding rail and the bracket becomes a non-negligible issue.

The difference between the sixth embodiment and the slide rail mechanism of the fifth embodiment is that: the first supporting portion 602 of the first bracket 600 further includes a first bending section 604, and the first bending section 604 and the side edge of the first rail portion 30a of the rail 22 can mutually support; the second supporting portion 606 of the first bracket 600 further includes a second bending section 608, and the second bending section 608 and the side edge of the second rail portion 30b of the rail 22 can mutually support.

According to this configuration, compared with the fifth embodiment, the first bracket 600 of the sixth embodiment can support the side edges of the first rail portion 30a and the second rail portion 30b of the rail 22 respectively by the first bending section 604 and the second bending section 608, so as to improve the reliability of supporting the rail 22, the first bracket 600 and the reinforcing member 500, and also help to strengthen the structural strength of the sliding rail mechanism.

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

a. when the first bracket 24 is adjusted to an arbitrary position (e.g., the first position P1 or the second position P2), the first bracket 24, the rail 22 and the reinforcement 26 have a supporting relationship with each other.

b. When the first bracket 24 is adjusted to an arbitrary position, the first supporting portion 34a of the first bracket 24 and the first rail portion 30a of the rail 22 can mutually support, the second supporting portion 34b of the first bracket 24 and the second rail portion 30b of the rail 22 can mutually support, and the reinforcement member 26, the longitudinal supporting portion 36 of the first bracket 24 and the longitudinal body 32 of the rail 22 mutually support together. According to this configuration, the structural strength of the slide rail mechanism is facilitated to be enhanced.

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.
