Self-harm prevention chair

Abstract

We provide self-injury prevention chairs to prevent injuries caused by self-inflicted injuries among users of nursing care facilities and similar institutions. [Solution] The present invention comprises a backrest, armrests, a seat on which the user sits, a table used by the user when eating, an extendable member that causes the seat to sink when the user sits, an L-shaped member connected to the seat and having a pivot shaft at its tip, and a stopper connected to the L-shaped member at the pivot shaft. In addition, protective covers to prevent self-injury are provided on both sides of the backrest.

Description

Technical Field

[0001] The present invention is an anti-self-harm chair that can protect users who repeatedly self-harm in nursing facilities and the like without restraining them.

Background Art

[0002] Conventionally, a table with casters that can be attached to a wheelchair has been used. During meals, the casters were equipped with stoppers, and the casters were responsible for attaching and detaching the table from the wheelchair. In nursing facilities for the disabled, there are many cases where people not only using wheelchairs but also those who hit their heads against the wall during meals due to self-harm behavior or fall due to panic caused by self-harm behavior are injured.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide an anti-self-harm chair that prevents injuries caused by self-harm or falls when the user is eating or sitting.

Means for Solving the Problems

[0004] The self-injury prevention chair of the present invention, which protects the user, comprises a backrest, armrests, a seat on which the user sits, a table used by the user when eating, an extendable member provided beneath the seat, an L-shaped member connected to the seat and having a pivot shaft at its tip, and a stopper connected to the L-shaped member by the pivot shaft. The stopper has a fitting hole at its tip and engages with the table when the user is not seated. When the user sits, the extendable member sinks, causing the L-shaped member to rotate on its pivot shaft, disengaging the fitting hole of the stopper and tilting the table forward so that the user can eat. Furthermore, since the user is seated within the hollow space of the table, protective covers provided on both sides of the backrest prevent the user from injuring themselves and causing severe blows, allowing the user to eat safely. [Effects of the Invention]

[0005] This can help prevent self-injury among residents of nursing homes and medical facilities while they are eating or engaging in activities while seated. [Brief explanation of the drawing]

[0006] [Figure 1] External view of a self-harm prevention chair [Figure 2] A side view of someone seated. [Figure 3] User Seating Chart [Modes for carrying out the invention]

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

[0008] Figure 1 shows an external view of the self-harm prevention chair 1. Figure 1 consists of a table 2 used by the user when sitting and eating, a backrest 3 from which the user leans when seated, protective covers 13 and armrests 5 on both sides of the backrest, and a seat 8. The protective covers 13 are provided to prevent the user from engaging in self-harming behaviors such as shaking their head.

[0009] Figure 2 shows a structural diagram illustrating the structure of the self-harm prevention chair 1. The self-harm prevention chair 1 consists of an L-shaped member 9 that connects to the seat 8, a rotating shaft 4 provided at the tip of the L-shaped member 9, a stopper 7 connected to the rotating shaft 4 and having a fitting hole at its tip, a backrest 3, a connecting shaft 6 that connects to the stopper 7, an extendable member 10 provided at the bottom of the seat 8, a table support part 11 provided approximately in the middle of the backrest 3, and a table 2 that connects to the table support part 11. The user will be seated inside the cavity 12. (Figure 3)

[0010] Figure 2 illustrates an example of how to use the self-harm prevention chair 1. When a user sits on the seat 8 of the self-harm prevention chair 1, the telescopic member 8 sinks, and the L-shaped member 9 sinks at the same time. Then, the table 2 detaches due to the stopper 7, which has a fitting hole, and the table 2 falls forward so as to surround the user.

[0011] Figure 3 shows the relationship between the user and table 2 during mealtime. Note that the user is seated inside cavity 12.

[0012] While self-harming behaviors such as shaking their heads during meals are sometimes observed among users, this is prevented by the protective cover 13. [Explanation of symbols]
