Description

Auxiliary rising cushion

Technical Field

The invention relates to the technical field of behavior auxiliary equipment, in particular to a seat cushion for assisting in getting up.

Background

With the aging development of the population, the elderly population with reduced physical muscles is increasing, and the very simple rising movement from sitting to standing for normal people becomes a problem for many elderly people. The existing rising products mainly focus on assisting old people to rise after sitting on a toilet, and only a small amount of products focus on assisting the old people to rise from the facilities such as a sofa, a seat and the like which meet daily indoor and outdoor sitting and rest. Present supplementary cushion of getting up mostly is hydraulic stem plus spring etc. from the energy storage type, and the spring that releases the compression when getting up lifts up the cushion, and the impact force is great, and use comfort is relatively poor, probably lead to the user to be lifted suddenly, has the risk of sliding down from the cushion.

The invention with the publication number of CN208573279U discloses a cushion capable of assisting in getting up, which controls the whole cushion plate to rotate and rise through a rotating handle to support the buttocks of a human body, so as to assist a user in getting up, wherein the rotating shaft of the cushion plate is the end close to the knees, the angle required to be lifted up by the cushion plate in the process of supporting the human body by the cushion plate is larger, the buttocks have the tendency of sliding down along the cushion plate, and even the buttocks have certain potential safety hazard because the legs are not supported enough to directly slide down and fall down.

Disclosure of Invention

The invention aims to provide an auxiliary rising cushion which can keep the gravity center of a human body stable and has high safety in the rising process.

The invention solves the technical problems through the following technical scheme: a sitting cushion for assisting in getting up comprises a base plate and a sitting plate which can be stacked, wherein the sitting plate comprises a front sitting plate and a rear sitting plate which are hinged and matched, the front sitting plate is hinged and matched with one end, close to a knee, of the base plate, a telescopic rod with two ends respectively hinged and matched with the base plate and the front sitting plate and a connecting rod with two ends respectively hinged and matched with the base plate and the rear sitting plate are arranged between the base plate and the sitting plate; the telescopic rod is hinged with one end of the front seat plate close to the rear seat plate, and is connected with one end of the rear seat plate far away from the front seat plate in a hinged mode.

When the auxiliary rising cushion is in a use state, the front seat plate and the rear seat plate are jointly supported as the seat plates, the buttocks of a person are always kept on the rear seat plate in the auxiliary rising process, the rear seat plate rotates and inclines relative to the rotating shaft to lift the buttocks, the rotating shaft of the rear seat plate is fixed on the front seat plate and can move upwards along with the front seat plate, so that the height of the rear seat plate is integrally lifted, the rear seat plate can lift the buttocks of the person without too large inclination angle, a user does not have too obvious tendency of sliding downwards from the rear seat plate, the use experience is good, and the safety is high; meanwhile, the rotating shaft of the rear seat plate can move forwards along with the front seat plate, so that the forward behavior of the human body is closer to the behavior law of the human body when the human body rises, and the comfort level is higher; under the condition that the inclination angle is not changed, the rear seat plate moves forwards, so that a user can get up more easily; the rotating shaft of the rear seat plate is fixed on the front seat plate, so that the whole rear seat plate can be kept in the vertical space where the seat plate is located, and the gravity center of a human body falls on the rear seat plate, so that the gravity center of the human body is always kept in the supporting range of the bottom plate, the gravity center of a user is kept stably supported, and the cushion is prevented from inclining; therefore, the auxiliary rising cushion can be safely applied to most of the conventional seats, wheelchairs and sofas.

Preferably, a soft cushion covering the front seat plate and the rear seat plate is arranged above the seat plate.

Preferably, the bottom plate is further provided with a battery module, the telescopic rod is an electric push rod, and the battery module is electrically connected with the telescopic rod.

Preferably, the battery module is also electrically connected with a control handle.

Preferably, the bottom plate is further provided with a handle.

Preferably, the connecting rod comprises a long cross rod, two ends of the long cross rod are respectively and fixedly connected with two vertical rods, the other ends of the two vertical rods are respectively connected with a short cross rod, the length directions of the two vertical rods are parallel, and the two short cross rods are coaxial; the long cross rods are hinged and matched with the rear seat plate, and the short cross rods at two ends are respectively hinged and matched with the bottom plate.

The auxiliary rising cushion provided by the invention has the advantages that: when the sitting plate is in use, the front sitting plate and the rear sitting plate are jointly supported to serve as sitting plates, during the auxiliary rising process, the buttocks of a person are always kept on the rear sitting plate, the rear sitting plate rotates and inclines relative to the rotating shaft to lift the buttocks, the rotating shaft of the rear sitting plate is fixed on the front sitting plate and can move upwards along with the front sitting plate, so that the height of the rear sitting plate is integrally lifted, the rear sitting plate can lift the buttocks of the person without too large inclination angle, a user does not have the tendency of sliding downwards from the rear sitting plate, the use experience is good, and the safety is high; meanwhile, the rotating shaft of the rear seat plate can move forwards along with the front seat plate, so that the forward behavior of the human body is closer to the behavior law of the human body when the human body rises, and the comfort level is higher; under the condition that the inclination angle is not changed, the rear seat plate moves forwards, so that a user can get up more easily; the rotating shaft of the rear seat plate is fixed on the front seat plate, so that the whole rear seat plate can be kept in the vertical space where the seat plate is located, and the gravity center of a human body falls on the rear seat plate, so that the gravity center of the human body is always kept in the supporting range of the bottom plate, the gravity center of a user is kept stably supported, and the cushion is prevented from inclining; thereby the auxiliary rising cushion can be safely applied to most of the prior seats, wheelchairs and sofas; compared with the prior art that the spring is used for storing energy, the electric push rod is used as a power source, so that the extension speed of the push rod is more accurately and conveniently controlled, the situation that a human body is suddenly jacked up by elasticity when the spring is released is avoided, the use experience is more comfortable, and the power assisting effect is better; the user can independently control the lifting of the rear seat plate through the control handle, the use is convenient, and the carrying is convenient by arranging the lifting handle on the bottom plate; when the auxiliary rising cushion is in a use state, the telescopic rod is contracted between the bottom plate and the seat plate, so that the whole auxiliary rising cushion is lower in height and can be directly added to the existing seat and sofa.
