When this conventional bearing member is attached, the bearing member is arranged on the floor surface and is directly fixed to the floor surface using screws or the like (see, for example, Patent Document 1).
JP 2001-323716 A

  When a conventional bearing member is attached to the floor surface, if the floor surface material is a tile or a carpet, there is a problem that inconvenience occurs during the construction. That is, when the floor material is a hard tile, the screw cannot be directly struck, and thus it is necessary to accurately and cleanly drill the screw mounting hole in the tile. On the other hand, in the case of a carpet with a soft floor material, drilling work is not required as in the case of tiles. However, since the screws applied to the carpet are easy to come off after construction, it is necessary to take measures to prevent them from coming off.

  In addition to the three-way frame type described above, there are types of entrance frames that are attached to the door, but there is a type with a lower beam called a four-way frame, but the bearing members for the four-way frame are attached to the lower beam. Therefore, the outer shape is formed in accordance with the shape of the lower beam (that is, a bearing member that matches the shape of each lower beam is required for a plurality of types of four-way frames).

  Therefore, not only can the bearing member for the three-way frame be used as the bearing member for the four-sided frame, but one type of bearing member cannot be used uniformly for a plurality of types of four-sided frames, and inventory management is complicated. There was also a problem of being.

  In addition, when a conventional bearing member is attached to the floor surface, it is generally performed that a pattern showing the attachment position of the bearing member is laid on the floor surface and this is used as a reference for the attachment position of the bearing member. Thus, there is a problem that it is troublesome to perform the positioning operation using the pattern paper.

  Furthermore, since the conventional bearing member is fixed to the floor so that the longitudinal direction of the bearing member is along the closed door, the long bearing member becomes conspicuous when viewed from the table, and there is also a problem that it is unsightly in appearance. .

  The present invention has been made in view of such conventional problems, and its main problem is that the construction is simple and can be used uniformly regardless of the material of the floor and the type of the entrance frame. It is an object to provide a door bearing member having a good appearance and a door bearing structure using the same.

The invention described in claim 1 is a door bearing member 20 that receives a lower pivot 18 of a door 16 that is hingedly attached to an inlet frame 14 of a storage space 12. There is an attachment portion 42 fixed to the crosspiece 14a and one end attached to the attachment portion 42 and a door support portion 44 that receives the lower rotation shaft 18 of the door 16, and the door support portion 44 is attached at one end thereof. It is possible to adjust the position in a direction substantially orthogonal to the width direction of the fixed-side door support portion 46 attached to the portion 42 and provided with notches 50 at both ends in the width direction, and the fixed-side door support portion 46. A guide protrusion 54 that is attached and fits into the notch 50 when attached to the fixed-side door support 46 and functions as a guide when the movable-side door support 48 is slid on the edge in the width direction end. Consists of a movable door support 48 formed. And has, widthwise one end portion of the movable door support 48 protrudes outward from the widthwise one end portion edge of the mounting portion 42, the lower pivot axis of the door 16 to the projecting portion component 44a The bearing member 20 is characterized in that a rotary bearing 30 for receiving the bearing 18 is formed.

The bearing member 20 according to the present invention is used by attaching the mounting portion 42 to the vertical beam 14a of the inlet frame 14, and the vertical beam 14a to be attached is usually made of wood, so the mounting of the bearing member 20 is performed. At the same time, there is no need for conventional troublesome work, that is, drilling work for tiles or measures for preventing slipping of carpets.

  Further, the bearing member 20 is attached to the vertical rail 14a of the entrance frame 14 instead of the floor surface, so that it is not necessary to change the shape of the bearing member 20 depending on the type of the entrance frame 14. That is, one type of bearing member 20 can be used in a unified manner regardless of the type of the entrance frame.

Furthermore , since the movable side door support portion 48 is attached to the fixed side door support portion 46 so that the position thereof can be adjusted, the position of the rotary bearing 30 can be adjusted after the bearing member 20 is attached to the inlet frame 14. . Therefore, when positioning the bearing member 20, there is no need for a pattern paper for positioning as in the prior art.
