Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor storage type sofa that can be stored in a space formed below a floor when not in use.

[0002]

[Prior Art]

 In order to effectively use the room, according to Japanese Utility Model Laid-Open No. 62-142955, the bed can be stored in a space formed below the floor by rotating the motor 180 degrees from the use position, It is well known that the back of the bed can be used as a floor. It is also well known that the bed can be moved up and down to a space below the floor and is closed by a sliding lid for the floor when the bed is stored.

[0003]

[Problems to be solved by the device]

 However, there is no storage type sofa that can be automatically retracted from its use position by a simple operation without closing the floor opening with a slide lid. In view of such a point, the present invention has an object to provide a floor storage type sofa that can be automatically moved between a use position and a storage position without requiring a slide lid.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, the present invention sets the depth of the seat portion and the longitudinal length of the backrest portion to be substantially equal to each other according to claim 1, and a backing member is provided on the back surface of the backrest portion. In order to make the seating part and the backrest part turnable into the space part, the space below the floor is opened corresponding to the bottom of the seating part, and the space part is formed at the depth corresponding to the depth dimension. The bottom end of the bottom is pivotally attached to the space side, the floor material is rotated from the vertical use position to the storage position where it is almost flush with the floor, and the seat and back rest are rotated by manual operation of the switch. It is characterized by having a driving device attached to it.

As a simple drive device which is not visible from the outside, according to claim 2, a motor attached to the seat portion, a drive gear protruding laterally of the seat portion, and rotationally driven by the motor, and a seat portion rotation. It is conceivable that the guide block is configured with a tooth profile that meshes with the drive gear along the rotation path of the drive gear during movement and that is arranged in the space.

[0006]

[Action]

 When the switch is manually operated for storage, the drive device rotates the seating portion and the backrest portion into the space so that the floor material on the backside of the backrest portion occupies almost the same plane as the floor. At that time, the shape of the back surface of the back support portion corresponds to the bottom surface of the seating portion, thereby closing the opening of the floor.

[0007]

【Example】

 1 and 2 show a floor storage type sofa according to an embodiment of the present invention. In the sofa 1, cushions are attached to the surfaces of the seating portion 1a and the backrest portion 1b, which have mutually the same horizontal width, and the depth dimension of the seating portion 1a and the lengthwise dimension of the backrest portion 1b are set to be substantially the same. Is configured. A floor material 19 made of the same material as the floor 2 around the installation location is attached to the back surface of the back support portion 1b. Below the floor 2 on which the seating portion 1a is placed, there is formed a space portion 11 having an opening corresponding to the shape of the bottom surface 10 of the seating portion 1a and having a depth corresponding to the depth dimension thereof.

A drive device for the sofa 1 described below is provided in the space and the seating portion 1a. First, a stay 15 is erected at a position corresponding to a bracket 12 (only one of which is shown in the figure) provided below both sides of the rear end of the bottom surface 10 in the space 11. A bracket 12 is attached to the tip end of the bracket 12, and a pin 16 is inserted and screwed to fix the bottom face 10 pivotally from a use position along the floor 2 to a storage position vertically below. There is. The pin 16 occupies a direction of 45 ° slightly downward from the edge 1c of the sofa 1, so that the floor member 19 is rotated 90 ° from the used state in which the bottom surface 10 is substantially flush with the floor 2. It is almost on the same plane as floor 2. A fin-shaped extension 19a of the floor member 19 reinforced by an angle 19b is formed downward from the edge 1c, so that the gap of the floor 2 during storage is almost eliminated. The stay 15 is formed with an escape portion 15a for the shaft 21 when stored.

A speed reducer and a motor 20 with a brake are installed at the center of the tip of the bottom surface 10. The shaft 21 is supported by bearings 22 on both sides, and drive gears 23 are fixed to both ends thereof. There is. In the space 11, arcuate guide blocks 25 having teeth 25a meshing with the drive gear 23 are formed on both sides along the rotation path of the drive gear 23 located slightly laterally outward of the seat 1a. It is arranged.

A limit switch 27 that comes into contact with the tip of the bottom surface 10 is attached to the lower end of the one stay 15, and the actuator 26 a attached to the reinforcing plate 3 also responds to the central portion of the tip of the bottom surface. A limit switch 26 is attached. As a result, in response to the operation of the switch 5 mounted on the wall, the motor 20 rotates in the normal direction from the use position until the limit switch 27 operates, and the limit switch 26 operates when returning from the stored position to the use position. Reverse until you do.

In the use state, the seating portion 1 a has the bottom surface 10 located at a position along the floor 2 and the motor 20 is braked to occupy the solid line position in FIG. 1. When the switch 5 is operated during storage, the motor 20 releases the brake and rotates in the normal direction, and the rotation of the drive gear 23 rotates 90 ° downward along the tooth profile 25a and stops. In this state, as shown by the chain double-dashed line in FIG. 1, the floor member 19 and the extension portion 19a close the space portion 11 on the same plane as the floor 2. At the time of use, operating the switch 5 on the wall returns to the use position.

[0012]

[Effect of the device]

 As described above, according to the invention of claim 1, since the back of the back support functions as a floor, the lid is automatically stored from the use position by simply rotating it without preparing a lid for the floor opening. become. Therefore, the floor automatic storage type software can be realized with a simple structure. According to the invention of claim 2, the drive device can be arranged on the back side or inside of the seating portion and in the space portion, and can be easily configured by using the motor without impairing the appearance.
