Therefore, when any two parts of the human body such as the left hip and the right hip are seated on the left bearing component and the right bearing component, the pressure on the left hip bottom and the right hip bottom can be reduced and balanced, and the effects of more comfortable pressure release contact feeling and righting posture are achieved.

Description

Constant pressure bearing device

Technical Field

The present invention relates to a carrying device for carrying a human body, and more particularly to a constant pressure carrying device capable of reducing the pressure on the human body contact portion, balancing the pressure, providing a more comfortable pressure release contact feeling, and correcting the posture when carrying the human body.

Background

Fig. 1 is a schematic view showing a state of a human body skeletal system when a human body sits on a chair, and fig. 2 is a schematic view showing an asymmetric structure of the human body relative to a symmetric chair surface when the human body sits on the chair, and please refer to fig. 1 and fig. 2, when the human body sits down, the weight of the upper half of the human body is supported on the pelvis, when the left and right sides of the pelvis of the human body are asymmetric, the left and right sides of the pear-shaped buttocks are not uniform in size, the left and right sides of the pelvis when the human body sits down are inclined, and the symmetrical chair surface can not be matched with and adjusted in height and supporting force, so that the chair surface pressure which is asymmetric in the left and right is generated, and the spines of the neck, the chest, the back, the waist and the hip can be inclined, so that the aching or discomfort of the neck, shoulder, the arm, the chest, the back and the waist and the legs can be generated.

In view of the above-mentioned pathological structure problem of left-right asymmetry of pelvis, the present inventors have previously proposed a patent technology for the above-mentioned problems occurring in general chairs and office chairs.

The relevant patent information refers to taiwan patent publication No. I714261 as a "hip-fitting chair", which includes a bracket, a seat cushion set is limited on the bracket, the seat cushion set includes a left cushion portion and a right cushion portion which are parallel to each other, a first elastic member and a second elastic member are positioned on the bracket, the first elastic member is linked below the left cushion portion, so that when the left half of the user's hip is seated on the left cushion portion, the left cushion portion is driven to move downwards and return to the original position after the pressure disappears; the second elastic component is linked below the right pad part, so that when the right half of the buttocks of a user sits on the right pad part, the right pad part is driven to move downwards and returns to the original position after the pressure disappears.

The utility model has the advantages that when the two half sides of the buttocks of a user are respectively seated above the left and right cushion parts, the height of the buttocks can be independently and automatically adjusted according to the difference of the sizes of the two half sides of the buttocks, the total bearing area is increased, and effective and comfortable decompression support is formed.

It can be clearly seen that the aforesaid patent applies the compressibility and elastic resilience of the first and second elastic members to achieve the purpose of independently and automatically adjusting the height according to the difference of the sizes of the two halves of the hip, and the embodiment of the first and second elastic members selects the compression spring, which is based on Hooke's law in the theory of mechanical elasticity, after the solid material (compression spring) is stressed, the stress and the strain (unit deformation) are in a linear relationship, so that the total bearing area of the left and right pad parts arranged above the left and right compression springs as the bearing assembly is increased, but the left and right bearing areas are not completely the same, and the left and right bearing weights are also different, so that the left and right pressures will also be different.

In summary, although the independent left and right cushion portions can independently and automatically adjust the height according to the difference of the sizes of the two half sides of the hip, the total bearing area is increased, and the pressure is reduced, the effect of balancing the pressure applied to the left and right hip bottoms is not achieved, and therefore, the comfort of releasing the pressure of the left and right hip bottoms is still improved.

From the above description, it is clear that there is a need for an innovative design and construction of the above-mentioned patent to balance the pressure applied to the left and right hip bottoms and provide a more comfortable pressure-releasing touch feeling. In view of the above, the inventor of the present invention has made an effort to develop and complete a constant pressure bearing apparatus of the present invention.
