Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hinge for mounting a gate.

[Conventional technology]

Generally, when a gate is rotatably attached to a pillar, a pair of hinges are attached to the upper and lower parts of the gate pole and the hinge is used to support the gate.
Very often there is a tilt to the left and right.

A hinge capable of correcting such a tilt of the gate after the gate is attached is described in Japanese Utility Model Laid-Open No. 62-54199.

The hinge described in the above publication is such that the adjustment gold is swingably attached to the upper and lower holding pieces of the fixed gold to be attached to the gate pole via a pin, and a support shaft for supporting the gate is provided on the top surface of the tip of the adjustment gold. The tilt of the gate, which is supported by the support shaft, is adjusted by swinging the adjustment gold about the pin.

In addition, a plurality of horizontally elongated holes are formed in the mounting piece provided on the fixed metal,
Tighten the mounting screws that are inserted into the horizontally long holes and screw-engaged with the gate posts to attach the fixed metal to the gate posts, loosen the above-mentioned mounting screws, and move the fixed metal in the lengthwise direction of the horizontally elongated holes to move the left and right sides of the gate. The tilt of the direction is adjusted.

However, in the above-mentioned hinge, when adjusting the inclination of the gate in the left-right direction, it is necessary to loosen the fixing screw of the fixed metal once fixed to the gate pole to move the hinge and the entire gate supported by the hinge in the left-right direction. Therefore, there is an inconvenience that the adjustment is time-consuming.

Therefore, the applicant of the present invention has proposed a hinge for mounting a gate that can adjust the tilt of the gate in the left-right direction without loosening the screw of the fixed metal (Japanese Patent Application No. 63-148565). In the hinge disclosed in Japanese Patent Application No. 63-148565, a box-shaped bulge portion is provided in a fixture, a support arm is inserted into the bulge portion, and an adjusting screw is provided between the end portion of the support arm and the end plate of the bulge portion. Are arranged. Further, in the bulging portion, an engaging plate is arranged between the support arm and the lower plate of the bulging portion, and a lock screw rotatably supported between the upper and lower plates of the bulging portion is fitted to the engaging plate.

In the hinge disclosed above, the support screw can be moved in and out, that is, the left-right direction of the gate can be adjusted by operating the adjusting screw.

Further, in the configuration disclosed above, the support arm after adjustment is fixed by operating the lock screw to press the engagement plate against the support arm, and sandwiching the support arm between the engagement plate and the bulging portion upper plate. It was

[Problems to be solved by the device]

The hinge disclosed by the applicant of the present invention is capable of correcting the inclination of the gate while the hinge is firmly fixed to the gate pole, and thus has much better workability than the conventional hinge for mounting the gate.

However, the hinge disclosed in Japanese Utility Model Application No. 63-148565 previously leaves a dissatisfaction with the fixing force of the support arm.

That is, in the above-mentioned hinge, as described above, the lock screw is operated to press the engagement plate against the support arm, and the support arm is sandwiched between the engagement plate and the bulging portion upper plate.

In other words, the support arm is only fixed by frictional forces. Therefore, there is a drawback that the support arm is displaced due to an impact such as a ball hitting the gate, and the gate is tilted.

Further, when the lock screw is firmly tightened in order to increase the fixing strength of the support arm, in the above-mentioned hinge, the engaging plate warps, and it is difficult to improve the fixing strength.

Although the fixing strength of the support arm is somewhat improved by providing the engaging plate with a notch, in the hinge disclosed above, since the flat portion of the engaging plate abuts the supporting arm, it is necessary to provide the engaging plate with a large notch. I couldn't. Further, in the hinge disclosed above, since the flat surface portion of the engaging plate abuts the supporting arm, even if a knurl is provided, the surface pressure of the knurl is small, and the biting of the knurl into the supporting arm cannot be expected at all.

Then, this invention makes it a technical subject to further improve the hinge for gates disclosed previously, and to provide the hinge for gates excellent in the fixing force of a support arm.

In order to solve the above problems, in the present invention, a fixture provided with mounting pieces above and below a bulging portion formed by an upper plate, a lower plate, and an end plate, and in the bulging portion of the fixture. The rear end portion is inserted, and the support arm is provided with a support shaft on the upper surface of the front end portion, and a lock member incorporated between the support arm and the upper plate or the lower plate. Is provided, and the tip end of the adjusting screw that is inserted into the screw insertion hole and is swingably supported is screw-engaged with the rear end surface of the support arm. A guide hole that is long in the direction, and a lock screw that is inserted into the guide hole and has both end surfaces rotatably supported by bulges is screwed into the lock member. A gap is provided between the surfaces to allow the swinging of the support arm, and the lock member has a cross section. Is concave, the support arms opposed to concave edge, toward a swinging direction of the support arm is of employing the configuration to form a Giza.

[Action]

In the above configuration, when the lock screw is loosened and the tip of the support arm is pushed or pulled, the adjustment bolt swings around the screw insertion hole formed in the end plate, and the support arm connected to the adjustment bolt is Rock. Therefore, the support shaft moves back and forth, and the tilt of the gate supported by the support shaft in the front-back direction can be adjusted.

Also, when the adjustment screw is rotated with the lock screw loosened, the support arm that engages with this moves in the axial direction of the adjustment screw, so the support shaft moves in the left-right direction and is supported by the support shaft. You can adjust the left and right inclination of the opened gate.

When the lock screw is tightened after adjusting the gate inclination as described above, the lock member moves in the axial direction of the lock screw and the serrations bite into the support arm, so the support arm is fixed and the gate is securely in the adjustment position. Can be fixed.

Particularly, in the hinge for a gate of the present invention, since the lock member is concave and the edge is provided with a serrated portion, a relatively large serrated portion can be adopted.

Further, since the knurls are on the concave edge facing the support arm, and the concave edge contacts the support arm, the surface pressure applied to the knurls is large. Therefore, the knurls bite into the support arm to firmly fix the support arm.

Furthermore, since the lock member has a concave cross section, it has a large section modulus and does not deform even if it is pressed against the support arm by a considerable force.
