The door opening and closing device with a support member is attached to a housing 1 of furniture such as a cupboard so that the door can be opened and closed with respect to the housing 1. The front surface of the housing 1 is open, and the opening is opened and closed by a door 2 indicated by a two-dot chain line in the drawing. 1A shows a state in which the door 2 is opened, and FIG. 1B shows a state in which the door 2 is closed.

  The door 2 is provided with a handle (not shown). When the door 2 is moved manually, the door 2 is opened. When the door 2 is moved downward, the door 2 is closed. In order to open the heavy door 2 with a small force, the door opening / closing device 4 incorporates a spring that generates a force that assists the operation when the door 2 is opened. Moreover, in order to reduce the impact when the door 2 is closed or opened, the door opening / closing device 4 is provided with a damper for braking the opening / closing operation of the door 2. When the door 2 is opened and closed, the door 2 moves in the vertical direction while maintaining a substantially parallel posture with respect to the housing 1. In order to realize the parallel movement of the door 2, the door opening and closing device 4 is provided with two links (auxiliary arm 6 and arm 7) that are substantially parallel to each other and have substantially the same link length. The detailed structure of the door opening / closing device 4 will be described later.

  The housing 1 is formed in a box shape, and includes an upper plate 1a, a pair of left and right side walls 1b, a bottom plate 1c, and a back plate 1d. A pair of left and right door opening / closing devices 4 are attached to the inner surfaces of the pair of left and right side walls 1b. In order to synchronize the operation of the door opening / closing device 4, the pair of door opening / closing devices 4 are connected by a connecting rod 5 as a connecting member.

  As shown in FIG. 2, when the pair of door opening / closing devices 4 are attached to the pair of side walls 1 b of the housing 1, the pair of door opening / closing devices 4 are connected by the connecting rod 5, and then the pair of door opening / closing devices are connected. The device 4 is attached to the housing 1. A pair of left and right support members 8 are attached to the corner portion of the upper plate 1a. The support member 8 is formed with a through hole 11 through which a fastening member 15 (see FIG. 4) such as a wood screw is passed. The support member 8 is fixed to the lower surface of the upper plate 1 a by the fastening member 15. An engaging portion 12 having an inverted T-shaped cross section is formed on the support member 8. The door opening / closing device 4 is formed with a groove-like engaged portion 21 that fits into the engaging portion 12 (see FIG. 6). The detailed structure of the support member 8 will be described later.

  The process of attaching the pair of door opening / closing devices 4 to the housing 1 is as follows. First, an operator fixes a pair of left and right support members 8 to the lower surface of the upper plate 1a of the housing 1 using a fastening member such as a wood screw. At this time, the operator supports the support member 8 so that the front surface side of the support member 8 is flush with the front surface of the upper plate 1a (so that the support member 8 is disposed in the same plane) and the side surface side of the support member 8 abuts against the side wall 1b. The member 8 is positioned. Next, the operator holds the pair of door opening / closing devices 4 in a state of being connected in advance by the connecting rod 5 with both hands, and engages the engaged portion 21 of the door opening / closing device 4 with the engaging portion 12 of the support member 8. The opening / closing device 4 is slid in one direction (the depth direction of the housing 1). As a result, the pair of door opening and closing devices 4 are attached to the pair of support members 8. When the door opening / closing device 4 is attached to the support member 8, the door opening / closing device 4 is positioned at a normal position of the housing 1. After that, as shown in FIG. 3, the operator fixes the door opening / closing device 4 to the inner surface of the side wall 1 b of the housing 1 with a fastening member 13 such as a wood screw. The door opening / closing device 4 has a through hole 22 through which, for example, two fastening members 13 are passed. After fixing to the side wall 1b, the door opening / closing device 4 is covered with a decorative cover.

You have to keep pressing. For this reason, screwing work becomes difficult.

  The structure of the support member 8 is as follows. As shown in FIG. 4, a pair of left and right support members 8 are attached to the corner portion of the upper plate 1 a of the housing 1. The support member 8 includes a plate-like main body 10 and an engaging portion 12 that protrudes downward from the main body 10. The support member 8 has a through hole 11 penetrating in the vertical direction in FIG. 4 and is fixed to the lower surface of the upper plate 1a by a fastening member 15 such as a wood screw.

  The main body 10 is formed in a rectangular plate shape. The main body 10 has a function of positioning the support member 8 with respect to the housing 1. Specifically, one side (first positioning portion) 10 a on the front side of the main body 10 is positioned in the same plane as the front surface of the upper plate 1 a of the housing 1. By positioning the one side 10 a in the same plane as the front surface of the upper plate 1 a of the housing 1, the support member 8 is positioned in the depth direction of the housing 1. Further, one side (second positioning portion) 10b on the side surface side of the main body 10 is abutted against the side wall 1b so that the support member 8 is parallel to the side wall 1b. The right angle formed between the front side 10a and the side 10b of the main body 10 is a right angle. The support member 8 is positioned in the frontage direction of the housing 1 by abutting the side 10 b on the side of the main body 10 against the side wall 1 b of the housing 1.
