Abstract

A handle mounting structure includes a handle including a handle shaft with a sliding space defined in one side thereof and a mounting unit located at one end thereof, a locking mechanism including an insert plate slidably inserted into the sliding space and a torsion spring mounted in the sliding space and stopped between the handle and the insert plate to impart a pressure to the insert plate toward the outside of the sliding space, and a positioning device including a flat base pivotally coupled to the handle and a hook block located at a bottom side of the flat base. The handle can be fastened to a sliding box of a cabinet through locking mechanism and the positioning device, so that the handle is not easily separated from the sliding box, and the sliding box can be surely pulled out of or pushed into the cabinet through the handle.

First claim

What the invention claimed is:

1. A handle mounting structure, comprising:
a handle comprising a handle shaft, a sliding space defined in one side of said handle shaft and a mounting unit located at one end of said handle shaft;
a locking mechanism mounted in said sliding space of said handle, said locking mechanism comprising an insert plate slidably inserted into said sliding space and a torsion spring mounted in said sliding space of said handle and stopped between said handle and said insert plate to impart a pressure to said insert plate toward the outside of said sliding space, said torsion spring comprising a coiled positioning portion mounted to said handle shaft within said sliding space, an abutment end piece extended from one end of said coiled positioning portion and stopped against said insert plate and a mounting end piece extended from an opposite end of said coiled positioning portion and positioned in said sliding space; and
a positioning device comprising a flat base pivotally coupled to said mounting unit of said handle and a hook block located at a bottom side of said flat base;
wherein said handle further comprises two position-limiting plates respectively curved from two opposite lateral sides of said handle shaft in direction toward each other with a gap defined between each said position-limiting plate; said locking mechanism further comprises an outer cover disposed at an outer side relative to said insert plate and covered on said two position-limiting plates of said handle over said sliding space, said outer cover comprising a plurality of positioning lugs respectively extended from two opposite lateral sides thereof and positioned in the said gaps between said two position-limiting plates and said handle shaft.

2. The handle mounting structure as claimed in claim 1 , wherein each said position-limiting plate comprises a plurality of insertion grooves disposed in communication with an inner side of said sliding space.

3. The handle mounting structure as claimed in claim 1 , wherein each said position-limiting plate comprises an arc-shaped lead edge located on an outer side thereof.

4. The handle mounting structure as claimed in claim 1 , wherein said handle further comprises a streamline-shaped grip extended from one end of said handle shaft.

5. The handle mounting structure as claimed in claim 1 , wherein said handle further comprises an opening defined in one end of the sliding space; said insert plate of said locking mechanism comprises a beveled sliding edge located on one end thereof, a retaining edge neighbored to a top side of said beveled sliding edge, and an abutment edge located on an opposite end thereof for abutment against said abutment end piece of said torsion spring.

6. The handle mounting structure as claimed in claim 1 , wherein said handle further comprises a mounting hole cut through said handle shaft and disposed in communication with said sliding space; said insert plate of said locking mechanism comprises an oblong sliding slot; said locking mechanism further comprises an outer cover disposed at an outer side relative to said insert plate and covered on said two position-limiting plates of said handle over said sliding space, said outer cover comprising a through hole; said locking mechanism further comprises a connection axle mounted in said mounting hole of said handle, said oblong sliding slot of said insert plate and said through hole of said outer cover for allowing said insert plate to be moved linearly relative to said handle and said outer cover.

7. The handle mounting structure as claimed in claim 1 , wherein said handle further comprises a locating hole cut through said handle shaft and disposed in communication with said sliding space; said coiled positioning portion of said torsion spring defines therein a through hole; said locking mechanism further comprises a positioning axle with a shank thereof mounted in said locating hole of said handle and inserted through the said through hole of said torsion spring.

8. The handle mounting structure as claimed in claim 1 , wherein said handle further comprises a positioning hole cut through said handle shaft and disposed in communication with said sliding space; said locking mechanism further comprises an outer cover disposed at an outer side relative to said insert plate and covered on said two position-limiting plates of said handle over said sliding space, said outer cover comprising a stop plate defining an abutment surface for the abutment of said mounting end piece and a mounting through hole cut through said stop plate and connected to said positioning hole of said handle with a fastening member.

9. The handle mounting structure as claimed in claim 1 , wherein said mounting unit of said handle comprises a mounting plate extended from said handle shaft, a mounting through hole cut through said mounting plate, an accommodation notch located on a top side of said mounting plate, a swirl space defined in an opposing bottom side of said mounting plate for allowing said flat base of said positioning device to move therein, and a top edge disposed at an inner side of said swirl space and neighbored to said handle shaft; said positioning device further comprises an engagement groove defined in said flat base for receiving said mounting plate, a spring member loaded in said engagement groove and positioned in said accommodation notch, an axle hole cut through said flat base, and a pivot axle mounted in said axle hole and pivotally connected to said mounting through hole of said mounting unit.

10. The handle mounting structure as claimed in claim 1 , wherein the winding direction of said coiled positioning portion of said torsion spring is parallel to the length direction of said handle; said abutment end piece defines with the horizontal line of said coiled positioning portion a predetermined contained angle within 0˜90°.

11. The handle mounting structure as claimed in claim 1 , wherein said positioning device further comprises a finger block extended from a top side of one end of said flat base; said hook block of said positioning device comprises a beveled guide edge located on a front bottom side thereof.
