Description

Improved structure of a ladder chair lift

technical field

The utility model relates to an improved structure of a stair lift chair, in particular to a structure in which the climbing and descending is controlled by wheel rail positioning and steel cables, and is matched with a foldable seat body, so that it has the characteristics of stable operation and convenient use.

Background technique

Most of the stair lift chairs used by people with disabilities today have power-giving structures installed inside the seat body, mainly through the motor to rotate the gears and the gear rails installed on the steps to generate the corresponding control of rolling up or down ; Although the structure of the lift chair in the prior art has realized the lifting of the chair to be conveniently controlled, there is still room for improvement in its structure in actual use, as explained below:

First, because the transmission structure of the lift chair in the prior art needs to be installed in the seat body, it must have a motor and a power storage device, and it is necessary to reserve a space for its placement, so that the seat cannot be reduced. Due to the volume occupied by the main body, there are restrictions on basic space installation.

Second, because the seat body needs to reserve space for the transmission structure in the prior art, it is difficult to make the seat body into a foldable structure, and it will not be able to provide the demand for changing the use state. Improve.

Utility model content

The purpose of this utility model is to provide an improved structure of a ladder lift chair in order to overcome the defects of the prior art.

The main purpose of the improved structure of the stair lift chair of the present invention is to provide the positioning of the movement of the seat body through the wheel rails, and to achieve smooth and stable climbing and descending through the control of the rolling and retracting of the steel cables.

In addition, since the transmission device of the lift chair is not installed in the seat body, it can reduce its occupied volume, and through the connecting rod structure between the armrest of the seat body, the seat cushion and the pedal, it can It has the control function of synchronous upward folding or lowering, which can quickly change the use state of the seat body.

In order to achieve the above object, the utility model adopts the following technical solutions:

An improved structure of a ladder chair lift mainly includes the following structures:

The chair lift device is mainly equipped with multiple poles on one side of the ladder, two wheel rails are arranged on the outside of the poles, and a stair handrail is added on the upper end of the poles;

The cable transmission box is connected with the climbing end of the wheel rail, and a steel cable stretching from the inside to the outside is hidden in one of the wheel rails;

The seat body is equipped with two wheel shafts at the rear end of the backboard, and a roller and a positioning piece are installed on the wheel shaft.

The rollers are clamped in the wheel rails, so that it has the positioning function when the seat body moves, and then the rolling and retracting of the steel cables is controlled through the cable transmission box, so that the seat body can climb along the wheel rails. or climbing action.

The two sides of the backboard of the seat body are provided with two side columns, and the side columns are connected with the armrests, chair pads and footrests through the contact points of the armrest, the seat pad and the footrest. A connecting rod is arranged between the chair pad and the pedal, and a back pad is arranged at the upper end between the two side columns.

The lower end of the pedal is equipped with a double-section rail structure that can stretch the pedal outward or shrink it inward.

The armrests, chair pads and footboards of the seat body can be folded upward synchronously to be in a vertical state or lowered to be in a horizontal state through the connecting rod.

The utility model has the following beneficial effects:

The improved structure of the ladder lift chair of the utility model provides the positioning of the seat body movement through the wheel rails, and through the control of the rolling and retracting of the steel cable, it can achieve smooth and stable climbing and descending.

In addition, since the transmission device of the lift chair is not installed in the seat body, the volume occupied by it can be reduced, and through the connecting rod structure between the armrest of the seat body, the seat cushion and the pedal, the It has the control function of synchronous upward folding or lowering, which can quickly change the use state of the seat body.
