Description

[Detailed Description of the Invention] This invention relates to a combination of a drop-in pin used in a hinge portion of a door, etc., and a driver for operating the pin.

A caulking pin like the one used for the lower part of the door in Figure 2 is used for the hinges of general doors, etc., but if this is also used for the upper part of the door, after the pin head is caulked, the It is completely impossible to remove the door without destroying the section.

This project was devised for the purpose of obtaining a hinge pin and a screwdriver for attaching and detaching it as a set, which can be easily removed when necessary.The structure is explained with reference to the drawings. 2 are side views of the door hinge portion of the storage, and FIGS. 3 and 4 are side views of the hinge pin and its driver according to the first and second embodiments of the present invention.

In the drawing, 1 is the main body of the storage cabinet in which the present invention is implemented, 2 is the upper frame, 3 is the lower hinge pedestal, 4 is the door, and 5
and 6 are pin receiver tubes provided at the upper and lower corners of the back surface of the door; 7 is a pin according to the first embodiment of the present invention; its head 8 has an internal thread 10 coaxial with the pin body 9;

11 and 12 are upper and lower insertion holes bored in the upper frame 2 and the hinge holder 3 at the opposing parts of the pin receiving tubes 5 and 6; A hole 13 for inserting a pin and a screwdriver is also made in the case.

Reference numeral 14 denotes a driver used when inserting and removing the pin 7 into and from the pin receiving tube 5, and an outer thread 15 that matches the inner thread 10 is cut at the tip thereof.

Reference numeral 17 designates a pin according to the second embodiment of the present invention, and an external thread 20 coaxial with the pin body 19 is cut in the head 18 of the pin.

Reference numeral 24 denotes a driver used when inserting and removing the pin 17 into and from the pin receiving tube 5, and an internal thread 25 that matches the external thread 20 is cut at the tip thereof.

Note that 31 is an ordinary caulking pin that passes through the hinge holder 3 and is inserted into the lower pin receiving tube 6, and the rear head 32 of the insertion pin is caulked to prevent it from falling off. (The lower pin has screw pin 4 as shown.
1 may also be used. ) The proposed hinge pin is used by dropping its main body 9 or 19 into the pin receiving tube 5 attached to the hinge part of a storage door, etc., like a normal hinge pin, but even after installation. Since the head 8 or 18 cannot be caulked, when removing the door, insert the tip of a screwdriver downward through the hole 13 and tighten the external screw 15.
Or connect the internal thread 25 to the internal thread 10 or external thread 2 of the pin.
If you pull it up after screwing it into the pin body 9 or 1
9 can be pulled out from the pin receiving pipe 5, and then tilting the upper part of the door slightly toward the front of the upper frame 2 and pulling it up will allow the door to move upward even if a normal pin hinge like the one shown in the figure is used for the lower receiving pipe 6. Since the withdrawal of the is free,
It has the advantage that the door can be easily removed.
