Description

Chair with rib support

Technical Field

The utility model belongs to the technical field of for the chair field, especially, relate to a chair with rib holds in palm, its improvement part is that the chair that has the waist among the prior art and holds in the palm the function reforms transform into a structure more brief, waist support function is better, sit and feel more comfortable, be suitable for the crowd wider, manufacturing cost more controllable chair with rib.

Background

The background art of the utility model includes the following prior art: "a folding waist-protecting chair" (see utility model patent application No. 200820012646.1), "a waist-protecting chair" (see korean patent application No. KR 1020150109360), "a chair for protecting waist" (see korean patent application No. KR 2020160005641), and other prior arts related to waist-protecting chairs (hereinafter collectively referred to as prior art solutions).

Although the prior art adopts rib supports or other waist support technical means, the following problems and disadvantages still exist.

First, in the case of conventional lumbar support chairs (e.g., ergonomic chairs), the support of the lumbar region by the chair back is limited to the support of the back ribs and the lumbar region, and little support is provided for the side and front ribs, so that the lumbar support function of the lumbar support chair is limited.

Secondly, as for the waist support chair with the annular rib support, namely, in the technical schemes of the three listed patent documents, the problems of not simple structure, not convenient and fast use, complex adjusting mechanism, not comfortable sitting feeling, high production cost, limited applicable crowd and the like exist in different degrees.

Disclosure of Invention

In order to solve the problem, the utility model provides a chair with rib holds in palm, its aim at designs a structure more succinct, waist support effect better, sit to feel more comfortable, be suitable for the crowd wider, manufacturing cost more controllable chair with rib holds in the palm.

To achieve the above objects, the present invention has the following considerations in view of the overall concept.

Firstly, the chair should be as simple and compact as possible in its construction, with as few components as possible to achieve the desired advantageous results.

Secondly, all waist support parts of the chair can realize 360-degree surrounding type support for the waist of the human body, so that the support force for the waist of the human body is greatly increased, and the pressure on the lumbar intervertebral disc tissues is further reduced.

Moreover, the adjustment of the angle and the tightness of the rib support needs to be convenient, and the user is prevented from being unwilling to use due to complex operation.

Fourthly, the addition of the rib support parts realizes seamless butt joint with the ergonomic chair in the prior art, so that the rib support and the waist support on the traditional chair back are mutually coordinated to play a role in supporting the waist together.

Fifth, the design, manufacture, and installation of the rib support need to be in consideration of cost, and the market acceptance cannot be affected by too high cost.

Finally, chairs are required to be oriented to a wide range of brainworkers engaged in office work and other market needs, rather than to medical institutions or to special populations with waist problems.

In order to achieve the above object, the utility model provides a chair with rib holds in palm, hold in the palm its characterized in that including chair leg, seat support, the back of the chair, two ribs of left and right sides: the left rib support is pivotally connected with the left side of the chair back through a hinge; the right rib support is pivotally connected with the right side of the chair back through a hinge; the two rib supports are mutually connected through a connecting belt arranged on the front ends of the rib supports or close to the front ends of the rib supports so as to adjust and fix the distance between the front ends of the two rib supports and the included angle between the rib supports and the chair back; when an adult user of a common size sits on the chair and connects and tightens the connecting belt, the two rib supports provide support for the lower half parts of the left and right ribs of the user; when the rib support is 90 degrees vertical to the chair back, in the direction parallel to the chair back, the section of the convex part of the rib support towards the direction of the chair seat is basically in a D-shaped or D-shaped horizontal overturning pattern under the state of not being squeezed; the two rib supports comprise a framework and an elastic material and/or a soft material. For the avoidance of doubt, the "left and right ribs" of the user shall refer to the majority of ribs on either side of the body's centerline, rather than the small portion of the "most lateral" ribs on the left and right.

The chair legs usually comprise legs for supporting the chair and chair legs contacted with the ground, and the number, shape and function (such as whether lifting, rotation, pulley and the like can be realized) of the chair legs are various, and the prior art has been recorded in detail and is actually applied to the production practice of the chair, but the invention points and the invention concept of the invention are not included, and the description is omitted here. The utility model is applicable to various chair legs, and the preferred embodiment of the utility model comprises a chair leg with lifting, rotating and pulley wheels.

Said seat is not substantially different from seats of prior art solutions, in particular from seats of ergonomic chairs. It should be noted that the rib support of the present invention cannot be obstructed by the seat (i.e. the sitting surface) during the pivoting process. Therefore, the related technical means of the chair seat belongs to the mature prior art in the field and is not described herein again.

The chair back can also contain a headrest to relieve the pressure on the cervical vertebra. To ensure that the rib rests can be securely mounted on both sides of the back, there must be components on both sides of the back that can be stressed, such as: stainless steel or alloy edge strips with the strength meeting the requirement are used for installing hinges on the part, so that the part can be pivotally connected with the rib support and can bear the pressure transmitted by the rib part after a normal human body sits down. It should be clear that the "sides" of the backrest are not limited to the "sides" of the backrest, and the specific location of the hinge may be moved to the center of the backrest for a suitable distance to achieve better pivoting and supporting effects. Therefore, the chair back related technical means belong to the mature prior art in the field and are not described herein again.

The number of the hinges can be one on one side or two or more on one side, and the specific number depends on the size of the hinges, the weight-bearing coefficient and the average height of the target people (for example, the height of European and American people is high, and the height of the rib support needs to be correspondingly increased, thereby possibly influencing the number of the hinges). The technical principle is substantially the same as the number of hinges required for the door and the doorframe. In addition, there are various types of hinges, which are conventional in the art and will not be described herein.

The connecting belt is not limited to a belt made of soft material (such as cloth, chemical fiber material, etc.), and may also be other equivalent components made of other materials (such as metal) with connecting, fixing, and pulling functions, such as a pulling hook made of stainless steel with adjustable tightness, or a sheet nylon buckle, etc. One of the preferred embodiments is similar to a safety belt used on an airplane seat, the locking, tightness adjustment and unlocking operations are convenient, the belt is not easy to deform, and the service life is long. In addition, the joint point of the connecting belt and the rib support is positioned on the front end of the rib support or at a proper position close to the front end, so that the pulling effect of the connecting belt and the rib support is optimal. Stitching or other conventional bonding means may be employed at the bond points. In order to improve the firmness degree of the combination point, the connecting band can further penetrate through the outer surface of the rib support and is fixed with the metal framework inside the rib support. This technical means is a mature prior art in this field and will not be described herein.

The adult users with ordinary statures refer to the persons with the key sizes of height, waist, hip circumference and the like within the range of the number of normal adults. The ribs of the user are divided into No. 1-12 ribs from top to bottom, and any side of the ribs forms an arc line longitudinally; the arc line formed by the No. 1-6 ribs on the upper half part is directed obliquely upwards, so that the chair cannot provide any support for the No. 1-6 ribs, and the arc line formed by the No. 7-12 ribs on the lower half part is directed obliquely downwards, so that the rib support can provide support force for the partial ribs. Therefore, after the connecting belt is connected and tightened, the two rib supports can tightly surround the left side, the right side and the front part of the ribs of the user, so that the two rib supports can provide large-area and uniform support for the lower half part of the ribs of the user. The specific tightness depends on the individual feeling and preference of the user and the duration of use. For example, after a user uses the mask for a long time, the rib contact portion may have a sense of discomfort of slight compression, so that the connecting band may be appropriately loosened.

When the rib support is perpendicular to the chair back by 90 degrees, the front end of the rib support is perpendicular to the chair back in a forward state. In the direction parallel to the chair back, the section of the convex part of the rib support towards the direction of the chair seat is basically in a D shape or a D-shaped horizontal overturning pattern under the state of not being squeezed, and the cross section of most of the rib supports is similar to the shape of an capital letter D, but is not strictly consistent with the shape of the capital letter D. So adopt the D design that appears, because of the D shape in the first half of right side pitch arc better with rib the latter half laminating degree, the space that the latter half pitch arc formed then conveniently holds user's buttock and thigh root, otherwise buttock and thigh root can receive long-time extrusion, lead to blood to flow unsmoothly. The convex part of the rib support towards the direction of the chair seat means that the utility model only concerns the shape of the convex part, and whether the other side part of the vertical bar in the D shape has a tangent plane is not concerned, such as O shape, although the manufacturer generally can not design the convex part.

The two rib supports comprise elastic materials and/or soft materials, and certain elastic materials and/or soft materials are arranged at corresponding positions in the rib supports, particularly positions in contact with human ribs, so that when the rib supports on the two sides clamp the human ribs, the two rib supports have high comfort level, can maintain supporting force and have a waist protecting function. The material is selected similarly to the corresponding material (i.e. the material which contacts the human body and plays a role of wrapping) in the sofa. One of the preferred embodiments of the elastic material is to select a high resilience polyurethane foam commonly used in the sofa field and mattress field; one of the preferred embodiments of the soft material may be a pad of pure cotton material. If the mite-proof requirement exists, natural latex materials can be added.

In order to enable the rib support to be provided with the hinge and be in pivot connection with the side of the chair back and simultaneously improve the supporting force and the service life of the rib support, a stainless steel or alloy framework with standard strength is required to be arranged in the rib support, the shape and the size of the framework are basically matched with those of the rib support and are reduced according to a proper proportion, so that sufficient elastic materials and/or soft materials are arranged on the outer layer. In order to increase the firmness of the framework, the framework is preferably manufactured by welding so as to ensure the integral rigidity of the framework. The producer can select specific framework materials according to market demands. In addition, the width of the upper edge of the rib support may be widened appropriately to function as a handrail at the same time. This part of the technical content is the mature prior art in this field and will not be described herein.

Because the utility model adopts the above technical scheme to can obtain following beneficial effect.

First, the utility model discloses the structure is comparatively brief, compares with traditional human engineering chair, and structural change is uncomplicated, only carries out adaptability to back of the chair avris and reforms transform (with the installation hinge), add in both sides simultaneously be used for holding in the palm the rib, protect the waist the part can, this part still has the handrail function concurrently. Belongs to the typical technical improvement of 'small investment and high output' and has higher marginal effect.

The second, owing to can form 360 degrees effect of embracing, the rib holds in the palm the combined action with the waist on the traditional back of the chair, makes the chair is soft or elastic material to the supporting effect greatly increased of human waist, and the part that in addition contacts with human rib and waist for user's sitting feels comparatively comfortable, can use for a long time.

Third, because the utility model discloses an overall structure compares with traditional chair and changes little, makes the suitable crowd of chair is wider to be not limited to medical structure or have the special crowd of lumbar vertebrae disease, but various environments such as widely used in office, meeting room, cinema, family's study, school, vehicle, commercial site, its potential market demand is higher.

Fourthly, the simpler structural design can be seamlessly connected with the manufacturing process of the ergonomic chair in the prior art, and the excessive designs of controlling the lifting and moving of the rib support parts by using parts such as a motor and a track in the prior art scheme are eliminated, so that the production cost of the chair is controllable, and the market acceptance of the chair is higher.
