Abstract

A simple closestool booster. Consists of a frame in the form of a hinge 4 linkage mechanism and a controllable gas spring. When a person goes to the toilet, the two arms straddle the handrail, and when the person sits downwards, the handrail connecting rod is pressed downwards to drive the upper cross beam to compress the gas spring. When needing to stand up after like the lavatory, pull spanner switch release air spring, the air spring promotes the entablature and drives handrail connecting rod and rise, helps like the people of lavatory to stand up from the closestool.

Description

Booster for toilet

The technical field is as follows:

the invention relates to a booster, in particular to a booster for assisting a person in defecation, which is used for a closestool.

Background art:

at present, an electromechanical closestool booster is available abroad, and the structure is complex, the cost is high, and the popularization is difficult. For people with weak leg muscles, the toilet is difficult to sit down and stand up. However, the difficulty can be solved by assisting a little force under the arm, so that the people can sit down slowly and stand up slowly when using the toilet. The invention designs the closestool booster which is simple in structure, does not need electric power, is convenient to use and is easier to popularize.

The invention content is as follows:

in order to solve the defects in the prior art, the invention adopts the technical scheme that:

the booster is mainly composed of two movable frames with hinges and 4-bar linkage mechanisms, and each movable frame is composed of a frame, 2 side links and a connecting bar. The frame is fixed on the wall, and 2 side links are connected on the connecting rod with the handrail. An upper cross beam capable of moving back and forth is arranged between the upper connecting rods of the two auxiliary frames, the lower parts of the two frames are connected with a lower cross beam, and a controllable gas spring is arranged between the upper cross beam and the lower cross beam. The controllable gas spring has a locking plate and a wrench switch, and the wrench switch is mounted on the armrest. When the air spring is compressed, the locking plate locks the air spring, and when the wrench is pulled to open and close, the locking plate releases the air spring to generate a pushing force outwards to lift the handrail. The side links of the frame are different in length, when the gas spring is pressed down, the handrail is in a horizontal position, and when the gas spring is released, the handrail is lifted and the front end of the handrail inclines downwards. The working process of the booster is as follows: when a person goes to a toilet, the two arms straddle the handrail, and when the person sits downwards, the handrail is pressed downwards to drive the upper cross beam to compress the gas spring. When needing to stand up after like the lavatory, pull spanner switch release air spring, the air spring promotes the entablature and drives the handrail and rise, helps like the people of lavatory to stand up from the closestool.

Description of the drawings:

fig. 1 is a mechanical structural view of the present invention.

In fig. 1: 1. the device comprises a rack, 2, a lower connecting rod, 3, a gas spring cylinder barrel, 4, a lower cross beam, 5, an upper connecting rod, 6, a cylinder rod, 7, an upper cross beam, 8, a handrail, 9 and a wrench switch.

The specific implementation mode is as follows:

the embodiments of the invention will be further explained with reference to the drawings in which:

fig. 1 is a mechanical block diagram with the decoration and accessories removed. The frame (1) is fixed on the wall, and the upper side link (2) and the lower side link (5) are hinged on the frame (1). The handrail (8) plays the role of a connecting rod, 2 holes at the rear part of the handrail are equivalent to hinges of the connecting rod, and the handrail (8) is hinged on the upper side link (5) and the lower side link (2). The handrail (8), the upper side link (5), the lower side link (2) and the frame (1) form a movable frame in a hinge 4 connecting rod form. The booster is composed of 2 pairs of identical movable frames, an upper cross beam (7) capable of adjusting the front position and the rear position is installed between 2 upper connecting rods (2), a lower cross beam (4) is installed on the lower portion of 2 racks (1), an air spring with a locking mechanism is installed between the upper cross beam (7) and the lower cross beam (4), an air spring cylinder (3) is installed on the lower cross beam (4), and an air cylinder rod (6) of the air spring is installed on the upper cross beam (7). The upper side link (5) is shorter than the lower side link (2), the specific length can be adjusted according to the use condition, the principle is that the handrail (8) is in a horizontal posture when the connecting rod mechanism rotates to the lower side, the handrail (8) is in an inclined posture when the connecting rod mechanism rotates to the upper side, and the front part is lower than the rear part so as to be convenient to use. The locking control mechanism of the gas spring is a spanner switch (9) which is arranged on the handrail (8) for convenient use. Under the control of a locking plate of the locking mechanism, the gas spring can move in one direction only, namely can retract and cannot be ejected. When the spanner switch (9) is opened, the locking plate releases the air spring, so that the cylinder rod (6) of the air spring extends out. When a person goes to a toilet, the person leans against the booster, the two arms are erected on the handrails (8) and sit downwards to the toilet, and the handrails (8) are pressed down by the two arms under the action of the weight of the human body. The booster (the hinge 4 connecting rod mechanism) moves downwards, the upper connecting rod (2) drives the upper cross beam (7) to press the air cylinder rod (6), and people can slowly sit on the closestool. When a person needs to stand up from the closestool, the two arms are still erected on the handrail (8), the wrench switch (9) is pulled, the locking plate of the locking control mechanism releases the air spring, the air cylinder rod (6) extends out of the air spring cylinder barrel (3) to jack the upper cross beam (7), the booster (the hinge 4 and the connecting rod mechanism) moves upwards, and the handrail (8) is pushed to lift the person. Because the legs do not need to exert force when a person sits down and the legs need to exert force when the person stands up, the lifting force can be smaller than the pressing force, and therefore the booster can easily help the person to slowly sit down and slowly stand up. A row of mounting holes are formed in the upper side link (2), the upper cross beam (7) is fixed to the upper side link (2) through bolts, and the positions of the upper cross beam (7) can be adjusted front and back by selecting the mounting holes in different positions. Due to the lever action, when the mounting position of the upper cross beam (7) is back, the lifting force of the booster is reduced; when the installation position leans forward, booster lifting force increases, can be fit for the people of different weight like this and use.
