Description

Activating the body chair with its own movement

The invention provides a technical field of a chair, in particular to provide a self-operating assisted lifting chair, wherein the bottom end of the two legs is arranged in an arc shape, the pedal strength causes the chair to lean forward, and the armrest is pivotally connected. Pull the rod, get up and press the rod at the same time so that the rod is pressed against the ground to make the chair more inclined, which makes it easier to get up.

Press, for the elderly, most of the time is in a sitting state, but there is still a need to get up, but often because of arthritis or poor blood circulation in the feet and lower limbs paralysis. At present, there is no chair that can be used to get up, so if you can have a chair that can be used in an institutional way, you can use the power to make it easier for the elderly to get up and get up on their own. Quite a good thing, but there are no related products on the market today, and there is a need for improvement.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, the consumers are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

In view of this, the inventor has been engaged in the production of related products for many years. With the development and design experience, after detailed design and careful evaluation of the above objectives, the invention will be practical.

The main object of the present invention is to provide a self-operating assisted lifting chair, wherein the bottom ends of the two legs are arranged in an arc shape, the pedal strength is used to tilt the chair forwardly, and the armrest is provided with a lever to pivotally connect the two levers, and the body is pressed at the same time to press the rod. The lever is placed against the ground to make the chair more inclined, which makes it easier to get up.

In order to achieve the above object, the present invention provides a self-operating assisted lift chair, which comprises: a left leg and a left armrest integrally formed, a right leg and a right armrest are integrally formed, and are fixed in the middle of the left and right legs. A seat back, a backrest is fixed in the middle of the back, and the main part is an arc-shaped round front end in front of the foot of the two chairs, an arc-shaped trap groove is arranged below the inner surface of the two legs, and a convex arc is arranged on the side of the circular arc The guiding groove of the shape is a pedal, and the two sides of the rear side are convexly arranged with a cylinder, the cylinder is slid to the guiding groove, the cylinder is pivoted with a front end of the rear rod, and two pressure bars are arranged on the armrest, and the front end of the two pressing rods A front end of the front pull rod is provided, and the rear end of the front pull rod is pivotally connected with the rear end of the rear pull rod. Accordingly, when the pedal is stepped up, the front end of the bottom of the chair is forced to be curved to generate a preliminary forward tilting motion, and the hand pressure is applied. The rod is such that the rear end of the front rod is restrained by the rear pull rod and is urged to the ground, and the chair is tilted forward to make it possible to get up and move forward.

Regarding the techniques, means and effects of the present invention, The above-described objects, structures and features of the present invention are believed to be apparent from the following detailed description.

The present invention provides a designer who assists in getting up the chair with his own action.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, the implementation method and the schema are as follows: Referring to the first to ninth drawings, the present invention provides a self-actuating assisted lift chair, which comprises: a left leg 11 and a left armrest 12 integrally formed; a right leg 21 and a right armrest 22 are integrally formed. a seat 30, the seat 30 is fixed in the middle of the left and right legs 11, 21; a backrest 40, the back 40 is fixed in the middle of the left and right legs 11, 21; The front left and right legs 11 and 21 are provided with arc-shaped round front ends 111 and 211, and the left and right legs 11 and 21 are respectively provided with arc-shaped traps 112 and 212, and arc-shaped traps 112 and 212. A curved groove guiding groove 113, 213 is arranged on the side of the arc circle; a pedal 51, a cylindrical portion 511 is protruded from the opposite ends of the pedal 51, and the cylinder 511 is slidably moved to the guiding groove 113, 213, the cylinder 511 A front end 521 of the rear pull rod 52 is pivoted, and a pressing rod 53 is respectively pivoted on the left and right armrests 12 and 22, and a front end 541 of the front pull rod 54 is pivoted to the front end 531 of the two pressing rods 53, and a rear end 542 and a rear pull rod of the front pull rod 54 are pivoted. The rear end 522 is pivotally connected to form the chair 1; accordingly, when the stepping pedal 51 is up, the front end of the chair 1 is forced to be coupled with the arcuate front end portion 111. The forward tilting action of the step, together with the pressing of the left and right armrests 12, 22, is such that the rear end 542 of the front pull rod 54 is restrained by the rear pull rod 52 and is urged toward the ground, and the chair 1 is tilted forward to cooperate. Getting up and tilting the chair forward 1 makes it easier to get up.

The self-actuating assisted lift chair, wherein the backrest A ventilation slot 41 is provided in the 40.

From the first to third figures, three stages of the operation of the chair 1 can be explained. The first stage (as shown in the first figure) is the chair 1 in the normal state, that is, the horizontal state; the second stage (such as The second picture shows), in the first step of general lifting, the foot is inwardly contracted and forced to kick up for a moment. After stepping on the pedal 51, the chair 1 is tilted forward; the final stage (as shown in the third figure) The display is also the last stage of displaying the overall movement. Before the body is lifted, the arm and the palm of the hand will support the pressure bar 53 of the handrails 12 and 22, and the chair 1 can increase the inclination angle, so that the lift is obtained when getting up. . In the case of force, the chair 1 is tilted and has a pushing effect when it is applied with the natural step of the body that is usually up, so that the body has a "semi-automatic" effect, which is convenient for the user to shorten. The time when the whole body got up.

It can be seen from the above that the self-operating assisted lifting chair of the present invention is indeed the first in the industry and meets the novel requirements of the invention patent, and its comprehensive innovative design conforms to the progressive requirements of the invention patent, and its two chairs The front end of the sole is set in an arc shape. The pedal strength makes the chair tilt forward. The armrest is set with the pressure rod pivotally connected to the two levers. When the body is pressed, the lever is pressed against the ground to make the chair more inclined, and the body can be more inclined. Easy, in line with better industrial use.

The foregoing description of the preferred embodiments of the present invention is specifically described as the technical features of the present invention; however, those skilled in the art can The present invention is subject to change and modification without departing from the spirit and scope of the invention, and such changes and modifications are intended to be included within the scope of the following claims.

In summary, the present invention provides a self-actuating assisted lifting chair, which has indeed achieved all the objects of the present invention, and the spatial type of the combined structure is not found in the same type of products, nor has it been disclosed before the application, and has been in compliance with the patent. The provisions of the law, 提出 apply in accordance with the law.
