Description

  The present invention relates to a storage with a door having a buffering function, and more particularly to a storage having a large number of storage parts arranged vertically and horizontally and a rotating door having a buffering function provided in each storage part. .

  2. Description of the Related Art Conventionally, a storage cabinet in which a large number of storage units are arranged vertically and horizontally and a rotating door is provided in each storage unit has been used as, for example, a locker or cabinet used by a large number of people. Many such lockers are installed in educational facilities such as schools, sports facilities such as golf clubhouses, and hot bath facilities.

  In this type of locker, multiple users may open and use the doors of different storage units at the same time, but users using the lower storage unit bent open the doors of the upper storage unit. If you stand up without noticing what is being done, the corners of the upper door may hit your head or body and cause injury. In particular, in the case of a steel locker, the corner of the door is formed at right angles by sheet metal processing, and the danger of the corner remains even if the top is carefully grindered and painted. Although it is not impossible to round the corners by drawing the steel plate, the manufacturing cost increases.

  As a measure for improvement, Patent Document 1 discloses a structure in which a corner cap made of an elastic body is attached to a lower corner portion of an open side end of a rocker door. Specifically, the corner cap has an outer piece that contacts the outer surface of the door, an inner piece that contacts the inner surface of the door), a lower piece that contacts the lower surface of the door, and an open end surface of the door. The lower piece is formed with a protrusion that engages with an engagement hole drilled in the lower surface of the door, and the side piece has an engagement hole drilled in the open end surface of the door. Engaging protrusions are formed. Here, in order to ensure the engagement between the protrusion and the engagement hole, the protrusion is formed with an engagement portion, and the engagement hole is formed by protruding a tongue piece from the center. The joint portion is engaged with the tongue piece of the engagement hole, and is configured to be resistant to peeling of the corner cap.

  However, since the structure described in Patent Document 1 has a structure in which a corner cap made of an elastic body is put on the corner portion of a steel door from the outside, it should be avoided that the corner cap protrudes from the outer surface of the door. It has a problem that the appearance is impaired. In addition, since the corner cap is merely held by engaging the tongue piece in the engagement hole and the engaging portion of the protrusion, the engaging portion of the protrusion is deformed when a strong force is applied to the corner cap. It is also possible that the protrusion of the corner cap material may be damaged due to aging of the corner cap material. In this case, the protrusion is inevitably dropped from the door.

  On the other hand, a technique of covering a synthetic resin skin material from the surface of the core material to the back surface of the peripheral edge is known as a three-dimensional surface decoration technique (TOM method). For example, Patent Document 2 has an upper molding chamber and a lower molding chamber that can be joined to and separated from each other and open on the opposite side, a heater is provided in the upper molding chamber, and a lifting table is provided in the lower molding chamber. After placing the core material on the lifting table and airtightly joining the upper molding chamber and the lower molding chamber with the periphery of the skin material between them, the upper molding chamber and the lower molding chamber are decompressed to the same pressure. The skin material is heated and softened by a heater, the table is raised, the core material is pressed against the skin material, the upper molding chamber is opened to the atmosphere, and a differential pressure is generated between the front and back surfaces of the skin material. A vacuum forming apparatus for covering a material with a core material in close contact with the core material is disclosed. And since the corner | angular part of a door is covered with a skin material by coat | covering with the skin material made from a synthetic resin from the surface of a steel door to the back surface of a peripheral part, a buffering effect can be expected to some extent, but it is not enough.
