"52 Tochigiya general catalog" issued by Tochigiya Co., Ltd.

  By applying the handle stopper mechanism described in Non-Patent Document 1 to a hinge, it is possible to turn the hinge blade by a certain angle. However, when this mechanism is applied to each pair of hinges, when the gears are disengaged, the cover member in each mechanism must be pressed using both hands, and there are not enough hands to turn the hinges. . Therefore, even if you use both hands, you will not be able to turn the hinge as you wish.

  Therefore, the present invention has an object to provide a novel hinge that can disengage the gear with one hand even if a gear for turning the blades at a certain angle is used for each pair of hinges.

  In order to solve the above-mentioned problems, the present invention is directed to include first and second blades, and a first sleeve and a second sleeve formed on each of the first and second blades are cascaded. Thus, the hinge is capable of rotating the first blade and the second blade a plurality of times by a certain angle through pins passed through both the sleeves.

  In this hinge, the features of the present invention are as follows. The first sleeve has a first end and a second end opposite to each other. The second sleeve has a third end and a fourth end that are opposite to each other, and the third end and the vicinity thereof enter the first sleeve from the second end and the first end. The fourth end and the vicinity thereof are located outside the second end without entering the first sleeve. The third end entering the first sleeve and the vicinity thereof are in a state in which they can rotate in the circumferential direction of the first sleeve and cannot be removed in the length direction, and the pin is attached to the second sleeve. An intermediate portion that is inserted in a state in which it cannot rotate in the circumferential direction and is slidable in the length direction and cannot be removed, and extends from the intermediate portion in the vicinity of the third end of the second sleeve. A front portion reaching the outside of the first end of the first sleeve, and a rear portion extending from the intermediate portion toward the outside of the fourth end in the vicinity of the fourth end of the second sleeve. Have. The entire pin is spring-biased in a direction from the fourth end toward the third end of the second sleeve, and the first blade and the second are between the first sleeve and the pin. The pin is formed on the pin with respect to the first angle regulating means formed on the inner side of the first sleeve in the vicinity of the first end so that the blade can be swung a plurality of times at the predetermined angle. Further, the second angle restricting means is engaged with the spring biased so as to be detachable from the length direction of the pin.

  In one preferred embodiment of the present invention, when the front portion of the pin is pressed from the first end toward the second end outside the first end of the first sleeve, the second angle is obtained. The restricting means separates from the first angle restricting means against the spring instability, so that the first blade and the second blade can freely rotate around the pin.

  In another preferred embodiment of the present invention, the first angle restricting means is an annular gear formed on the inner peripheral surface of the first sleeve, and the second angle restricting means is the peripheral surface of the pin. And a gear that is removably meshed with the annular gear.

  In another preferred embodiment of the present invention, a third angle restriction is provided on an inner peripheral surface of the second sleeve in order to rotate the first blade and the second blade a plurality of times by the predetermined angle. And a fourth angle restricting means is formed on the rear portion of the pin. The fourth angle restricting means is detachably engaged with the third angle restricting means under the spring bias. The restriction of the turning angle between the first blade and the second blade by the four-angle restricting means is synchronized with the restriction of the turning angle by the first and second angle restricting means.

  In still another preferred embodiment of the present invention, the hinge is used as a first hinge, and a second hinge identical to the first hinge is paired with the first hinge to form the first hinge. The rear part of the pin in the first hinge and the front part of the pin in the second hinge are opposed to each other and between the rear part and the front part. A connecting rod member is interposed, and a rear portion of the pin in the first hinge is engaged with one end portion of the rod member so as to be detachable from the length direction of the rod member, and the second hinge The front portion of the pin is engaged with the other end of the bar member so as to be removable from the length direction of the bar member.

  In the hinge according to the present invention, the pin is inserted into the first sleeve provided on the first blade and the second sleeve provided on the second blade, and formed on the first angle regulating means and the pin formed on the first sleeve. Since the second angle restricting means thus engaged is detachably engaged, the first blade and the second blade can be swung by a certain angle a plurality of times by both means.

  Such hinges can be arranged in a plurality of hinges only by pressing them with one hand against the spring bias if a plurality of such hinges are arranged and the pins under spring bias are connected by a connecting rod. Since the engagement of the angle restricting means is disengaged, the other party to which the blade is attached can be turned with the other hand.
