JP2002295112A - V-shaped hinge - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a hinge capable of realizing a closed state from a half-open state only by the hinge without depending upon a door checker or the like in order to avoid the half opening of a door which damages the effect of air conditioning and often caused trouble. SOLUTION: In the hinge in which an upper hinge 1 and a lower hinge 2 are connected by pins 3, the V-shaped hinge has a structure in which corrugated undersides 1-3 are formed to the underside of an upper cylinder 1-2 and the top face of a lower cylinder 2-2 as the rotary sliding surfaces of the hinge respectively and a corrugated top face 2-3 to the lower cylinder 2-2 and the hinge is opened and closed by its own force by door own weight or the like until the crests and valley of the wave forms reach angles where the crest and valley are fitted mutually when the hinge is opened and closed gradually, and stopped at the fitted angles.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge used for an entrance door of a general building.

[0002]

2. Description of the Related Art Conventionally, hinges used for doors have little backlash and are intended to open and close smoothly, so the door itself has no function of opening and closing, and the door is opened halfway depending on the person who handles it. There are many cases, which hinder the indoor cooling and heating effect. Conversely, in summer, when you want to open the door and improve ventilation, the door closes due to the direction of the wind. In many cases, door checkers are used to prevent this.

[0003]

The hinge does not rely on a door checker or the like, and merely by attaching a hinge does not allow the door to remain in a half-open state without being loose and cannot be closed. A hinge that allows the door to close on its own by simply attaching the hinge to the door is desired. The present invention has been invented to realize this desire.

[0004]

An upper hinge 1 and a lower hinge 2 are provided.
Are provided with a corrugated lower surface 1-3 and a corrugated upper surface 2-3 on the lower surface of the upper cylinder 1-2 and the upper surface of the lower cylinder 2-2, respectively, which are rotation sliding surfaces of the hinge. The V-shaped hinge has a structure in which the door is opened and closed by its own weight or the like until the peaks and valleys of the waveform come to an angle that fits each other, and stops at the fitted angle.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. At the hinge where the upper hinge 1 and the lower hinge 2 are connected by the pin 3, the corrugated lower surface 1-3 and the lower cylinder are provided on the lower surface of the upper cylinder 1-2 and the upper surface of the lower cylinder 2-2, respectively, which are the rotational sliding surfaces of the hinge. 2-2 is provided with a corrugated upper surface 2-3, and when the hinge is opened and closed, the door is opened and closed by its own weight, etc., until the peaks and valleys of the corrugation come to an angle that fits each other, and stops at the fitted angle. V-shaped hinge. When using this, attach this hinge to the top and bottom of the door when using it for a door. FIG. 8 shows an example of a hinge used for switching the angle of a lighting support arm 5 attached to a desk. Attach the lower cylinder 2-1 to the tip of the pole 6, and attach the upper cylinder 1-2 to the root of the lighting arm 5,
A disc spring 7 is mounted thereon. Further, as shown in FIG. 9, the angle of the arm 5 can be set to a desired angle by making the pitch of the waveform small.

[0006]

According to the present invention, the door is not loosely opened halfway just by attaching the hinge,
It is possible to prevent the indoor cooling / heating effect from being impaired. Further, the lighting support arm with the hinge can be set at a desired angle.
