Double guide mechanism

Abstract

Provided is a duplex guide rail mechanism operated smoothly and quietly.A main body projection part 10T is provided on the front part of a main body side rail 10, an association roller 20N is freely rotatably attached at a position of an intermediate rail corresponding to a position P2' on the front side by a prescribed amount [delta] from a rear end position P1' of the main body projection part in the pull-out completion state of the intermediate rail 12 to the main body side rail, and a pull-out body projection part 14T is provided over a prescribed range [delta] on the rear side from a position P1 of a pull-out body side rail corresponding to a position of the association roller in the state where the retreat of the pull-out body side rail 14 to the intermediate rail is completed. Connection mechanisms 30 and 14H are provided such that the intermediate rail and the pull-out body side rail are moved together in the process of pulling out a pull-out body from a housing completed state and having the association roller reach the main body projection part and the process of completing housing after the association roller separates from the main body projection part and they are separated at the other time.

Description

technical field [0001] The invention relates to a compound guide rail mechanism used for smoothly pulling out and re-storing pull-out bodies of office furniture such as cabinets or household furniture. A pull-out body generally refers to an object to be pulled out, including a drawer and a table to be pulled out. Background technique [0002] Some cabinets and other double guide rail mechanisms have: the drawer-side track installed on the drawer side, the main body-side track installed on the frame (main body) side, and the cylindrical (cylindrical) track between each track. A roller or spherical ball that can move relative to the middle track. For example, Patent Document 1 below discloses an example of such a structure. As stated in the document, attached to the document Figure 6 (a), (b2), and (c) are pulled out in the order and stored in the reverse order, so that the effect of reducing the load on the predetermined rotating body can be achieved. In other words, when...

Problems solved by technology

[0004] However, when pulling out in such a sequence, when the middle rail is stopped relative to the rail on the main body side, due to its reaction force, an impact force is generated to stop the rail on the side of the drawer being pulled out, which prevents the rail mechanism from being smooth. , a reason for moving quietly
