Description

Technical Field

[0001] The present invention is a sofa that can be utilized when restraining a person with impaired mobility in, for example, a nursing facility.

Background Art

[0002] As a conventional restraint device, there is a truncheon for capturing rioters. However, when using a truncheon, even if one is accustomed to using it, there is a risk of severely hitting the body or head of a person with impaired mobility against a wall or the ground. In addition, by placing the truncheon in a visible storage location, there is a risk that a person who is concerned about the storage location may end up destroying the truncheon. For these reasons, it is difficult to use and store in facilities or homes.

[0007] The embodiments for carrying out the invention will be described with reference to the drawings.

[0008] Figure 1 shows the exterior of the sofa. Sofa 1 consists of a backrest 2, cushions 3, arms 4, and a frame 5.

[0009] Figure 2 shows a disassembled view of sofa 1 with cushion 3 removed. Cushion 3 is located at the bottom. U-shaped gripping part It has 31. The frame 5 has a mating groove 51 on the seat surface 52 and a locking opening 53 on the side. The locking part 6 has a handle 61 at its end.

[0010] Figure 3 shows a cross-sectional view of the side of cushion 3. U-shaped gripping part 31 has a plate 32 made of soft poly material located approximately in the middle of the cushion 3. Both ends of this plate 32 are bent outwards.

[0011] Figure 4 shows a cross-sectional view of the bottom surface of cushion 3. The plate 32 U-shaped gripping part 31 has a threaded portion 33 which is screwed in with a screw or bolt.

[0012] The bottom view of the cushion is shown in Figure 5. The end of the locking part 6 has a handle 61. The locking part 6 is U-shaped gripping part It penetrates and is inserted into part 31.

[0013] The bottom view of the frame is shown in Figure 6. Frame 5 is U-shaped gripping part It has a mating groove 51 into which 31 fits and a locking groove 54 into which the locking part 6 is inserted from the locking opening 53. Note that the mating groove 51 is as shown in Figure 5. U-shaped gripping part 31 is a groove into which it fits.

[0014] Next, an example of the use of the present invention is shown in Figure 7. When using the cushion, the user 7 takes the handle 61 of the locking part 6 through the locking opening 53 formed on the side of the frame 5 and pulls it out towards him, removing the locking part 6. This allows the cushion 3 to be moved freely. The user 7 removes the cushion 3, U-shaped gripping part Grasp 31. Using this cushion 3, the movements of the person 8 in a panic state can be restricted on the top surface of the sofa 1. In this way, the person 8 in a panic state is safely restrained.
