Patent Document 1 described below discloses a technique for bringing a seat chair with wheels to an object such as a bed and transferring a user to the object. The width of the wheel portion is the maximum width in the product.
JP 2002-85461 A

  However, in the above-mentioned thing, since the part with the largest width | variety in a product becomes a wheel part, when it approaches to the width direction with respect to a bed, a clearance gap will be produced between a bed and a seat surface by wheel width. For this reason, when the user moves from the seating surface to the bed, a known sliding board or the like must be used to eliminate the gap, and the user cannot easily transfer.

  Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a seat chair that can improve transferability.

In order to solve the above-mentioned problem, the technical means taken in the present invention, as claimed in claim 1, is connected to a leg portion installed on the floor and the leg portion, and receives a driving force. In a seat chair comprising a seat surface that moves up and down, a backrest that can be tilted backward with respect to the seat surface, and armrests that are provided on both sides of the seat surface, the armrest can be flipped up with respect to the backrest. When the armrest is flipped up, the width of the seating surface is wider than the width of the backrest, and the bed can be arranged in parallel with no gap .

In order to solve the above-mentioned problem, the technical means taken in the present invention is, as claimed in claim 2, connected to the leg part installed on the floor and the leg part, and receives the driving force. In a seat chair comprising a seat surface that moves up and down, a backrest that can be tilted backward with respect to the seat surface, and an armrest provided on both sides of the seat surface, when the armrest is tilted in the width direction of the seat surface A flat portion that is continuous with the seating surface is formed, and the seating surface and the flat surface portion are wider than the backrest in the width direction of the seating surface, and are parallel to the bed through the flat surface portion without any gap. This is a configuration that can be set up.

According to the present invention, when the armrest is flipped up, it becomes wider than the width of the backrest in the width direction of the seating surface, and the width of the seating surface becomes the maximum width in the seating chair. For example, a bed or a wheelchair can be lined up closely in the width direction of the seating surface without a gap. Thereby, the user of a seat chair can transfer easily with a target object from a seat surface, and the transferability of a seat chair can be improved.

According to the present invention, when the armrest is tilted in the width direction of the seating surface, a flat portion continuous to the seating surface is formed, and in the width direction of the seating surface, the seating surface and the flat surface portion are wider than the width of the backrest. and the width of the combined flat portion becomes the maximum width of the seat, the plane portion and the object to be continuous with the seat surface (eg bed or a wheelchair) and be arranged snugly without any gaps in the width direction of the seat surface it can. Thereby, the user of the seat chair can transfer the object from the seat surface to the object more easily through the plane portion, and the transferability of the seat chair can be improved.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view of a seat 1 according to the present invention. The seat chair 1 includes a leg portion 2 and a seat surface 3. The leg portion 2 is a portion that is installed on the floor surface 4 and supports the seat chair 1. The seat surface 3 is a part where a user of the seat chair 1 sits. The seat surface 3 is connected to the leg portion 2 and moves up and down by receiving a driving force from an actuator (not shown). The seat chair 1 further includes a backrest 5 that can be tilted backward with respect to the seat surface 3 and an armrest 6 that can be flipped up. In the seat chair 1 according to the present embodiment, the width of the seat surface 3 is the maximum width in the seat chair 1. According to this structure, for example, as shown in the figure, when the seat 1 and the bed 7 are used together, the seat surface 3 and the bed 7 of the seat 1 are perfectly fitted in the width direction of the seat 3 with no gap. Can be arranged. Thereby, the user of the seat chair 1 can easily transfer from the seat surface 3 of the seat chair 1 to the bed 7 after jumping up the armrest 6 without using a known sliding board or the like.

  FIG. 2 is a perspective view of a seat chair 11 according to another embodiment of the present invention. The seat chair 11 includes a leg portion 12 and a seat surface 13. The leg portion 12 is a portion that is installed on the floor surface 4 and supports the seat chair 11. The seat surface 13 is a part where the user of the seat chair 11 sits. The seat surface 13 is connected to the leg portion 12 and moves up and down by receiving a driving force from an actuator (not shown). The seat chair 11 further includes a backrest 15 that can be tilted backward with respect to the seat surface 13 and an armrest 16. The armrest 16 is movable and can be tilted in the width direction of the seating surface 13 as shown in FIG. The fallen armrest 16 forms the same surface (surface of the same height) as the seat surface 13 and forms a flat surface portion 17 that is continuous with the seat surface 13 in the width direction. In the seat chair 11 according to the present embodiment, the total width of the seat surface 13 and the flat portion 17 is the maximum width of the seat chair 11. According to this structure, for example, as shown in the figure, when the sitting chair 11 and the bed 7 are used together, the flat surface portion 17 and the bed 7 that are continuous with the seating surface 13 are arranged without gaps in the width direction of the seating surface 13. You can line up exactly. Thus, the user of the seat chair 11 can more easily transfer from the seat surface 13 of the seat chair 11 to the bed 7 via the flat surface portion 17 without using a known sliding board or the like.

  FIG. 3 is a perspective view of a seat 21 according to another embodiment of the present invention. The seat chair 21 includes a leg portion 22 and a seat surface 23. The leg portion 22 is a portion that is installed on the floor surface 4 and supports the seat chair 21. The seat surface 23 is a part where a user of the seat chair 21 sits. The seat surface 23 is connected to the leg portion 22 and moves up and down by receiving a driving force from an actuator (not shown). The seat chair 21 further includes a backrest 25 that can be tilted backward with respect to the seat surface 23 and an armrest 26. The armrest 26 is movable and can move downward with respect to the seat surface 13 as shown in FIG. The armrest 26 moved downward forms the same surface as the seat surface 23 (surface of the same height), and forms a flat portion 27 continuous with the seat surface 23 in the width direction. In the seat chair 21 according to the present embodiment, the combined width of the seat surface 23 and the flat portion 27 is the maximum width of the seat chair 21. According to this structure, for example, as shown in the figure, when the seat 21 and the bed 7 are used together, the flat portion 27 and the bed 7 that are continuous with the seat 23 are connected to each other with no gap in the width direction of the seat 23. You can line up exactly. Accordingly, the user of the seat chair 21 can more easily transfer from the seat surface 23 of the seat chair 21 to the bed 7 via the plane portion 27 without using a known sliding board or the like.

The perspective view of the seat 1 which concerns on this invention. The perspective view of the seat 11 which concerns on other embodiment of this invention. The perspective view of the seat 21 which concerns on other embodiment of this invention.
