BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding type hinge used for doors and the like.

[0002]

2. Description of the Related Art A pair of hinge pieces are used, each hinge piece is provided with a fitting hole, and a hinge for slidingly fitting a hinge pin into the fitting hole is used for opening and closing a door or the like. It is known as one of the hinges. In order to open and close the door smoothly, it is necessary to make the sliding fit of the hinge pin into the fitting hole as tight as possible. At the same time, as the degree of sliding for this sliding fitting becomes denser, it becomes necessary to skillfully perform air bleeding from the fitting hole. On the other hand, as one of the conventional techniques, there is a technique in which a hole for venting air, which opens from the hole toward the outside, is provided at the tip of the inner part of the fitting hole.

[0003]

When the fitting hole has the air vent hole as described above, the oil supplied to the fitting hole in order to improve the opening and closing of the door leaks from the hole, and the hinge. There was a problem that the area around was soiled with oil. Therefore, the present invention is intended to solve the above problem by preventing oil leakage by providing a cap member capable of closing the pores from the outside.

[0004]

In order to solve the above-mentioned problems, the gist of the present invention is to extract a pair of hinge pieces and a hinge pin which is slidably fitted into a fitting hole formed in these hinge pieces. Assuming a differential hinge, a cap member that is provided at the tip of the inner part of the fitting hole with an air vent for opening to the outside from the fitting hole and that is capable of closing the hole from the outside. The cap member has a support portion that can be inserted into and removed from the pore, and the closing is performed by fitting the support portion into the pore.

Further, in a preferred embodiment of the present invention, the cap member also serves as a blind for a screw fixing hole provided in the hinge piece.

[0006]

[Operation and effect] In the hinge having the above-mentioned structure,
The support portion of the cap member is fitted into the air vent hole from the outside to close the hole. Therefore, even if oil is applied to the fitting hole of the hinge piece, oil does not leak from the hole, and the surroundings thereof are not contaminated with oil during use of the hinge.

[0007] The cap member also serves as a blind for the hole for fixing the screw of the hinge, which helps to arrange the appearance of the hinge and reduces the finishing work around the hole for fixing the screw, which contributes to the reduction of the manufacturing cost of the hinge. To do.

[0008]

The details of the hinge according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a use state of the hinge 1 according to the present invention. In the figure, a hinge 1 is composed of a pair of metallic hinge pieces 3 having substantially the same shape, which are vertically opposed to each other, and a space between the hinge pieces 3 is a washer 4 made of a self-lubricating plastic material or the like. Is intervened. One of the pair of hinge pieces 3 is fixed to the door 5 and the other is fixed to the fixed wall 6 by screws 11 described later. The pair of hinge pieces 3 are rotatably supported by a hinge pin 8, which will be described later, incorporated therein. An appropriate number of hinges 1 are used for the door 5. A cap member 7 is attached to one end of each hinge piece 3.

FIG. 2 is a sectional view taken along the line II-II in FIG. 1 and shows the internal structure of the hinge 1. Hinge piece 3
Has a screw hole 10 perpendicular to the door 5 or the fixed wall 6 and is attached via a screw 11 fitted in the screw hole 10. In the figure, screw holes 10 are provided at least at both upper and lower ends of each hinge piece 3, and each hinge piece 3 can be reliably fixed by these plural screws 11. Each of the pair of hinge pieces 3 has a fitting hole 12, and a hinge pin 8 is slidably fitted into the hole 12 so as to be rotatable about the pin 8 as a shaft. A washer 4 made of a material having a small friction coefficient such as the self-lubricating plastic described above is interposed as a sliding member between the surfaces 19 of the hinge pieces 3 facing each other.
With such a structure, the door 5 can be opened and closed with respect to the wall 6.

It is preferable that the hinge pin 8 is slidably fitted into the peripheral wall of the fitting hole 12 as closely as possible in order to make the movement of the hinge smooth. In order to quickly perform such a sliding fit, an air vent hole 13 having an opening 14 toward the outside is provided at the distal end of the fitting hole 12. In response to fitting the pin 8 into the fitting hole 12, air is released from the pore 13. A cap member 7 for closing the opening 14 from the outside is attached to the pore 13. The cap member 7 is preferably made of a material having appropriate elasticity such as a plastic material or rubber in order to realize the outer shape described later.

FIG. 3 is a partial exploded perspective view of the hinge 1 showing the structure of the cap member 7 with a part cut away and the method of attaching the cap member 7 to the hinge piece 3. The cap member 7 is attached by fitting the free end of the cylindrical support portion 16 standing upright inside the member into the pore 13. The free end of the support portion 16 has an outer shape substantially matching the opening 14 of the pore 13 or slightly larger than that, and
It has a slit 17 at the tip. Due to the presence of the slit 17, the supporting portion 16 is fitted into the pore 13 while elastically deforming its free end, and is not easily separated. As is apparent from FIGS. 1 and 2, the outer shape of the cap member 7 is appropriately designed so as to have a sense of unity with the outer shape of the hinge piece 3. In that case, a portion of the hinge piece 3 with which the peripheral edge of the cap member 7 abuts can be provided with a step corresponding to the thickness of the cap member 7 so as to be a guide when the cap member 7 is attached. The inside of the cap member 7 is appropriately hollowed out so as to facilitate its molding to form a cavity, and such a cavity is located at, for example, the upper end of the screw hole 10 provided in the hinge piece 3. The screw hole 10A to be used (see FIG. 2) and the head of the screw 11 used here are covered so as to be a blindfold. In particular, the hinge 1 as shown in the drawing has screw holes 10B to 10D (see FIG. 2) located below the hinge piece 3, and the screw 11 used therein has the presence of the other hinge piece 3 forming a pair. It is possible to arrange the design to be those blindfolds. Therefore, screw holes 10
If A and its screw 11 can be blindfolded by the cap member 7, the hinge 1 has no screw hole at first glance and can be finished in an extremely elegant design. In addition, since it does not require time and effort to finish the appearance around the screw hole 10A, it contributes to the reduction of the manufacturing cost of the hinge 1.

By the way, the mutual rotation of the hinge pieces 3 can be made smoother by lubricating the fitting hole 12. With the hinge 1 according to the present invention, the fitting hole 12
Since the support portion 16 of the cap member 7 that acts as a blind plug by closing this from the outside is fitted into the pore 13 provided at the tip of the inner part of the oil, oil does not leak from the pore 13,
There is no oil stain around the hinge 1.

In addition to the diameter of the pores 13 in the above embodiment, the diameter may be small enough to act as an air vent, and may be large enough to prevent the hinge pin 8 from falling off.
