Pull-out aiding device and chassis-wall module with pull-out aiding function

Abstract

A pull-out aiding device is configured for mounting on an object, in which a corresponding apparatus is mounted. The pull-out aiding device includes a pulling member and a handle member. The pulling member includes a first pivot section and an abutting section for abutting against the corresponding apparatus to move the latter forward. The handle member includes a second pivot section and an operating section. The second pivot section is pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section relative to the pulling member and brings the latter to move forward.

What is claimed is: 
     
         1 . A pull-out aiding device for mounting on an object, comprising:
 a pulling member including a first pivot section and an abutting section;   a handle member including a second pivot section and an operating section; and the second pivot section being pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section; and   a releasable fastening element being movably connected to the operating section of the handle member; the releasable fastening element including a receiving space for movably associating with the operating section of the handle member and a retaining section for detachably engaging with a first object; or the releasable fastening element including a body portion movably associated with a receiving space of the operating section of the handle member.   
     
     
         2 . The pull-out aiding device as claimed in  claim 1 , wherein the receiving space of the releasable fastening element and the operating section of the handle member are associated with each other via pin connection means, such that the releasable fastening element and the handle member are movable relative to each other within a limited range; or wherein the receiving space of the handle member and the body portion of the releasable fastening element are associated with each other via pin connection means, such that the releasable fastening element and the handle member are movable relative to each other within a limited range. 
     
     
         3 . The pull-out aiding device as claimed in  claim 1 , wherein the receiving space of the releasable fastening element has an elastic element disposed therein with an end of the elastic element pressed against the receiving space and another opposite end against the operating section of the handle member, such that the releasable fastening element and the handle member are movable relative to each other within a limited range and can be elastically pushed by the elastic element back to their original positions; or wherein the receiving space of the handle member has an elastic element disposed therein with an end of the elastic element pressed against the receiving space and another opposite end against the body portion of the releasable fastening element, such that the releasable fastening element and the handle member are movable relative to each other within a limited range and can be elastically pushed by the elastic element back to their original positions.
