Problems solved by technology

[0005] like image 3 As shown, when the gear 106 departs from one end of the rack 104, and the gear 106 intends to re-engage with the rack 104 from the end again, usually the second rail 102 is manipulated by the user. Displacement from an open position to a direction D10, during this process, due to the tooth tip 112 of one of the teeth 110 of the gear 106 and the tooth side 114 of one of the teeth 107 of the rack 104 may be Form a right-angle relationship and cause a direct impact, resulting in noise and an unsmooth feeling of displacement

Embodiment Construction

[0029] Such as Figure 4 and Figure 5 As shown, the embodiment of the present invention provides a gear device 20 configured on a furniture component such as a slide rail assembly 21, wherein the gear device 20 includes a rack 22, a gear 24, and a flexible member 26 attached to the rack 22. The slide rail assembly 21 includes a first rail 36 , a second rail 38 , and a third rail 40 . Wherein, the first rail 36 is a fixed rail, the second rail 38 can be regarded as a movable rail relative to the displacement of the first rail 36, and the third rail 40 is movably installed on the first rail 36 and the second rail 36. Between the two rails 38 , the displacement stroke of the second rail 38 relative to the first rail 36 can be extended.

[0030] The rack 22 is fixedly installed on one of the first rail 36 and the second rail 38. In this embodiment, the rack 22 is fixedly installed on the first rail 36, and along the Length direction setting. The rack 22 has a first end porti...

Abstract

The invention relates to a gear device. The gear device comprises a rack, a gear and a flexible part, wherein the rack comprises a plurality of teeth; the gear can be meshed with the rack through theteeth; the flexible part is arranged at one end adjacent to the rack, and the flexible part is used by the gear.

Description

technical field [0001] The invention relates to a gear device, in particular to a gear device capable of reducing the noise and unsmooth feeling when the gear device is re-engaged. Background technique [0002] In a furniture system, taking a drawer system as an example, usually a drawer can be opened or closed relative to a cabinet by means of a pair of slide rail assemblies. Among them, through the engagement of a gear and a rack, the stability of the drawer relative to the displacement of the cabinet can be improved. For example, US Patent No. US 9,243,662 B2 discloses a configuration of a gear device, which is hereby incorporated This article is for reference only. [0003] Further, as attached to this case figure 1 As shown, a first rail 100 and a second rail 102 are displaceable relative to the first rail 100 . Wherein, a rack 104 is disposed on the first rail 100 , and a gear 106 is disposed on the second rail 102 . Through the cooperation of the gear 106 and the ...
