Description

Automatic lifting-moving chair device for paraplegic patients capable of lifting and moving

The present invention relates to an automatic lifting-moving chair device for paraplegic patients, and more particularly, it can easily move to a destination where a person with a paralyzed or inconvenient lower extremity or a patient wants to move while seated, and the height can be adjusted according to the use environment. It relates to an automatic lifting-moving chair device for a patient with lower extremity paralysis that can be used by elevating and lowering, and in particular, enabling easy use in the bathroom and improving safety and stability.

In general, various types of chairs are used to allow a person to maintain a comfortable sitting posture or to sit according to the height of a desk.

The traditional form of such a chair has been provided with a seat that supports the user's buttocks and a fixed backrest that can be supported by leaning against the user's back, but has been developed into more various forms for convenience of use.

In particular, patients with reduced mobility, the elderly, or the disabled live with the help of caregivers or dependents. However, when caring for patients or the elderly, caregivers or their dependents were frequently injured by the load of the patient or the elderly in the process of moving or sitting and standing.

Therefore, in recent years, various elevating chairs that assist patients or the elderly to sit or stand up have been disclosed.

The Republic of Korea Utility Model Publication No. 20-0362853 discloses a bogie with casters attached to the lower portions of the front cross member and the rear cross member respectively attached to the front and rear surfaces of the horizontal frame, and vertically attached from the upper part of the horizontal frame of the bogie. There is proposed a multi-purpose chair composed of a lifting support member, a lifting frame coupled to be liftable from the lifting support member, and a backrest hinged rotatably horizontally and vertically from the tip of the lifting frame.

However, in the prior art, the height adjustment of the seat is very complicated and inconvenient because it has a very complex structure in which the height of the seat is adjusted using the fitting coupling action by the fixing protrusion and the groove installed on one side of the lifting frame and the lifting support member. In a state in which the height of the body is adjusted, as the fixing protrusion is separated from the groove, the lifting frame whose fixing force is released rapidly descends along the lifting support member, thereby causing a safety accident.

In addition, in the case of a seat including a backrest in the prior art, since the structure is simply installed on the bogie side by the lifting support member, the chair is very easily transferred as the center of gravity is tilted in one direction, and in the case of the backrest, the lifting frame There are other problems, such as a remarkably lowered seating comfort of the backrest due to the simple fastening structure at one end.

In addition, Japanese Patent Application Laid-Open No. 1995-067739 discloses a multifunctional chair in which a reclining function is provided by adjusting the angle of the backrest in addition to elevating the seat.

1 is a view showing an elevating operation and a reclining motion of a chair disclosed in the Japanese Patent Laid-Open Patent Document, the elevating motion (a), the reclining motion of only the backrest without changing the angle of the seat (b), the angle of both the seat and the backrest It can be seen that the bending operation (c) of the changing form is configured to be possible.

However, according to the prior art, since the user had to manually manipulate the seat 4 and the back 5 during the bending operation, considerable inconvenience was accompanied.

In addition, the conventional elevating chair is limited only to the height function of the chair, so there is a problem in that the functionality is poor.

Republic of Korea Patent Publication No. 10-2014-0145717 (published on December 24, 2014) Republic of Korea Registered Utility Model Publication 20-0362853 (2004.09.22.
