Description

[Detailed description of the invention] This invention relates to a door hanging pin, which has a synthetic resin head on the top of a metal pin, a thin synthetic resin film around the metal pin directly below the head, and a synthetic resin locking member with a locking protrusion on the bottom, and which consists of a vertical piece and a horizontal piece extending to one side from the upper end of the vertical piece, with a notch provided from the tip of the horizontal piece towards the vertical side, and a metal pin mounting piece having an opening at an appropriate position on the vertical piece below the notch, with the metal pin fitted into the notch,
To provide a door hanging pin mounting device which is mounted by fitting a locking protrusion into an opening, and which enables the door to be opened and closed smoothly by eliminating unpleasant metallic noise generated between the door hanging pin and a metal support plate having a long notch when the door is slid, and which also has an object to provide a door hanging pin mounting device which can reliably and easily mount the door hanging pin to a pin mounting piece.

As shown in FIG. 1, a conventional door hanging pin has a head 2 made of synthetic resin screwed onto the top of a metal pin 1 having male threads at both ends.
Therefore, when this door hanging pin is screwed onto a female screw attached to the top of the door, and the door is suspended from a metal support plate with a long notch and the door is slid, the metals will come into contact with each other. The problem was that it produced unpleasant noises. Also, the attachment of the door hanging pin was not secure.

This invention eliminates the above-mentioned drawbacks, and will be explained in detail below using examples.

Figure 2 is a cross-sectional view of the door hanging pin used in this invention, 3 is a metal pin such as stainless steel,
Reference numeral 4 denotes a large diameter synthetic resin head provided on the top of the metal pin 3. A thin film 5 made of synthetic resin is also formed around the metal pin 3 directly below the head 4 made of synthetic resin. This thin film 5 is applied at the same time when the metal pin 3 is inserted into a split mold containing liquid synthetic resin and solidified, and then the split mold is split and the synthetic resin head 4 is attached to the metal pin 3. The split mold is previously shaped so that the thin film 5 can be formed around the metal pin 3. Synthetic resins include nylon, acetal, vinylon,
Any material such as polycarbonate may be used.
Reference numeral 6 denotes a substantially rectangular parallelepiped-shaped locking member provided at the bottom of the metal pin 3, and a locking protrusion 7 is provided on one side of the locking member 6. The tip of the locking protrusion 7 is shaped like an anchor so that once it is locked to the member to be locked, it cannot be easily removed.

On the other hand, as shown in FIG. 3, the metal pin attachment piece 8, which is a member to be locked, consists of a vertical piece 9 and a horizontal piece 10 extending to one side from the upper end of the vertical piece 9, and both ends of the vertical piece An opening 11 is provided near the opening 11 which projects slightly in the same direction as the horizontal piece 10 and into which the locking protrusion 7 of the door hanging pin is fitted.

In addition, a notch 12 is provided near both ends of the horizontal piece 10 from the tip of the horizontal piece toward one side vertically, and the metal pin 3 of the door hanging pin is inserted into this notch 12, and at the same time the locking protrusion 7 is fitted and locked into an opening 11 formed in the vertical edge 9. At this time, the lower end of the thin film 5 formed around the metal pin 3 comes into contact with the horizontal piece 10 of the pin attachment piece 8. 13 is a screw hole for fixing the pin mounting piece 8 to the door. In addition, when precision of the pin attachment piece 8 is required, it is better to manufacture it by punching or bending a metal plate using a metal mold.

FIG. 4 is a side sectional view showing the state in which this invention is used, and the pin attachment piece 8, to which door hanging pins are fixed at both ends, is attached to the upper part of the back surface of the door material 14 with screws. Reference numeral 15 denotes a top plate of a storage box such as a shoe rack, and a metal support plate 17 having a long notch 16 is attached to the lower front surface of the top plate with screws 18. The door hanging pin is supported by being hooked onto the metal support plate 17 using the notch 16 of the metal support plate 17, thereby suspending the door.

As mentioned above, this idea uses a synthetic resin thin film around the metal pin directly below the synthetic resin head, so even if the door with the door hanging pin attached to it slides. This has the advantage that it does not produce any unpleasant noises like metal rubbing against metal, and the door can be opened and closed smoothly. In addition, a rectangular parallelepiped-shaped locking member is provided at the bottom of the metal pin, and a locking projection is provided on one side of the locking member, so that the locking projection can be inserted into the opening provided in the locked member. By matching, the door hanging pin can be easily attached to the locked member. Moreover, the metal pin is fitted into a notch provided in the horizontal piece of the pin mounting piece, so the door hanging pin is 2
It also has the advantage of being a point support and can be installed reliably.

In addition, if the synthetic resin head of the door hanging pin and the thin film are provided in a continuous manner, the metal pin will be securely fixed to the synthetic resin head.
Even when hanging a heavy door, the synthetic resin head will not fall out from the metal pin during use.
