Description

  The present invention relates to a hinge device and a joinery.

  In addition to what is referred to as a “hinge”, there is a hinge device that is applied to a joiner as a “pivot hinge”. A hinge connects the side edge parts of a pair of hinge brackets by a support shaft and is rotatably supported so as to open and close each other. On the other hand, the pivot hinge is configured such that a pair of hinge brackets facing each other are connected to each other by a support shaft orthogonal to them, and are supported rotatably with respect to each other. In a pivot hinge type hinge device, for example, one hinge bracket is provided with a support shaft, and the other hinge bracket is provided with an insertion hole. By inserting the support shaft into the insertion hole in a rotatable manner, two hinges are provided. Brackets are rotatably supported relative to each other. According to this type of hinge device, since the dimension along the axial direction can be reduced as compared with a hinge type device, for example, the fitting is arranged between the upper surface of the door and the lower surface of the upper frame. It is possible to configure.

  On the other hand, with pivot type hinge devices, it is difficult to ensure a sufficient dimension along the axial direction of the support shaft. For example, when the opening frame is deformed by an external force during a disaster such as an earthquake, the opposing hinge brackets If the distance is increased, the support shaft may deviate from the insertion hole of the hinge bracket. When the support shaft deviates from the insertion hole of the hinge bracket, it is difficult to support the door with respect to the opening frame, and the door falls off from the opening frame. In order to prevent such a situation, in the pivot type hinge device, a flange having a diameter larger than that of the insertion hole is formed at the upper end portion of the support shaft, while the insertion hole is opened around the hinge bracket, and the opening is formed through the opening. Thus, the support shaft is inserted through the insertion hole (see, for example, Patent Document 1). According to such a hinge device, even when the distance between the opposing hinge brackets is increased, the flange is engaged with the hinge bracket to prevent the support shaft from deviating from the insertion hole, thereby preventing the door from falling off. Become so.

Further, although the locking bracket 60 is attached to the upper frame 11, it is not always necessary to provide the locking bracket 60.

  Furthermore, in the above-described embodiment, the engagement member 44 is exemplified as a cylindrical member that fits on the outer periphery of the upper support shaft 43. However, as long as the engagement member 44 is movable along the axial direction of the engagement member 44. It is not always necessary to fit the outer periphery. For example, it is possible to form a hole at the center of the upper support shaft 43 and provide a shaft-like engagement member inside the hole. Moreover, although the flange-shaped thing protruded from the perimeter of the engaging member 44 is illustrated as the engaging part 44a, it does not necessarily need to be a flange-like shape, and protrudes outward along the radial direction. If the plurality of projecting portions are provided as long as they face the peripheral edge of the opening of the insertion hole, the same effect can be obtained. In the above-described embodiment, when the flange-like engagement portion 44 a is provided, the engagement portion 44 is disposed at both ends of the engagement member 44. Although it is not necessary to care about the orientation of 44a and the assembling work can be simplified, it is sufficient that the engaging portion 44a is provided only at the upper end portion of the engaging member 44.
