Abstract

A sitting device (100) for prevention of spinal diseases comprises a padded member (200), a thin pad (300) extended forwardly from the padded member (200), and a hard block (400) fully inserted inside the padded member (200). The padded member (200) has a generally hexagonal shape, and is made of resilient materials. The hypotenuse surface (201) of the padded member (200) is undulating economically The hard block (400) is made of a non-resilient material, and is able to tolerate, without rupturing, the gravity force on a mass of an adult's body with a shape and size similar to those of the adult's buttocks. The hard block (400) is inserted completely inside the right angle area of the padded member (200). The height (H) of the front side (403) of the hard block (400) is greater than the distance from the lowest point of the sitter's coccyx to the lowest point of his tuberosity of the sacrum. This will always keep the sacrum in a position higher than that of two seating areas keeping the pelvis upright and symmetric. Both the padded member (200) and the hard block (400) have a flat bottom side to ensure stability.

Description

Seated device for preventing spinal diseases

This creation relates to a sitting device, and more particularly to the occurrence of a user sitting on a flat surface to prevent spinal diseases such as cervical, thoracic and lumbar diseases.

Wrong sitting posture can lead to many spinal diseases. The correct sitting posture (such as Figure 8) refers to keeping the pelvis in a position that does not deviate from the middle of the spine, just like the position of the pelvis when a person is standing, the left pelvis and the right pelvis are The erect, symmetrical arrangement is on both sides of the humerus and above the position of the sacrum sitting position and in the middle. When the pelvis is in the middle position, the spine will not tilt to the right or left side, and the natural curve of the spine will be like an S-shape, which means that the weight of the whole body will be evenly distributed in the spine and intervertebral disc. As a result, spinal disease is less likely to occur. However, when sitting on a flat surface, such as a floor, it is quite difficult to maintain the same sitting position at any time to maintain the pelvis in the middle position. Because the foot and the hips are on the same plane, as the pelvis slides forward, the position of the tibia will be lowered, so that the spine must be bent, and the posture change will change the spine curve from S shape to C shape. The anterior portion of the vertebrae is compressed and opened at the posterior end, causing back pain due to excessive pressure and squeezing the intervertebral disc, causing the disc to protrude backwards to compress the nerves, spinal cord, pelvis and tibia. The tail vertebrae are deflected and twisted, losing balance and causing pelvic shape. Changes such as pelvic deformation, hunchback and natural spine curve changes. In the long run, wrong sitting posture can lead to many spinal diseases, such as Cervical, thoracic and lumbar diseases. Therefore, a person will feel joint pain, tension headache, stress and fatigue in the back and neck, as well as many other health problems, including disc herniation, spondylolisthesis and other diseases. For the wrong sitting posture, please refer to Figure 8b and Figure 8c. Figure 8b is a schematic diagram of the severe wear of the spine due to poor sitting posture, and Figure 8c is a schematic diagram of the degenerative wear and tear of the spine due to poor sitting posture. In fact, most people will sit on a flat surface, such as sitting on the floor for a long time for different reasons. For example, work, meditation or participation in religious courses. When sitting on the floor, if there are no supporting objects to keep the pelvis in a straight line, you will soon experience back pain or the above-mentioned spinal disease. A number of devices have been developed to provide spinal support when sitting on a flat surface. However, existing devices do not provide stable support to maintain the pelvis in an intermediate position, the key being that existing devices do not provide the correct sitting posture. For example, in the cushion-futon used by the meditator, it is filled with fluffy soft fluff material, and a futon or cushion will raise the buttocks and partially absorb the reaction force generated by the floor when the weight of the sitter is pressed down to the floor. The seated person's sitting posture is a folding leg or a cross-legged sitting posture, also known as a lotus sitting posture, which is the only comfortable posture. However, because the futon uses fluffy filling material, it does not provide sufficient support. The pelvic and caudal vertebrae of the meditation will tilt in different directions according to different sitting postures, which will eventually lead to back pain or other spine problems. U.S. Patent No. 6,141,807 discloses an adjustable height pillow for promoting proper sitting posture. However, the pillow is filled with a soft, resilient filler that is primarily shaped to accommodate the entire buttocks. Therefore, it is impossible to provide a stable support of the pelvis to maintain the pelvis in the middle position. A resting/sleeping structural pillow is disclosed in U.S. Patent No. 5,652,983, which provides sufficient comfort when seated thereon. However, the pillow also does not provide a stable support of the pelvis to maintain the pelvis in an intermediate position.

It will be appreciated from the foregoing that a device must be provided for the user to sit on a flat surface. The sitting device must provide a stable support having a stepped shape for the nucleus of the tibia and the tail vertebrae and the stiffness of the ischial tuberosity, maintaining it from being collapsed or tilted by the user's weight, and maintaining a use. The pelvis is in an intermediate position, which maintains the user's pelvis and tibia in an upright and symmetrical state, thus avoiding spinal diseases caused by tilting, bending or hunchback of the spine. Therefore, the sitting device can prevent spinal diseases caused by many wrong sitting postures, such as cervical, thoracic and lumbar diseases.

The main purpose of this creation is to provide a sitting device for protecting the spine and the tibia.

According to an embodiment of the present invention, a sitting device for preventing a spinal disease includes: a filling member, a thin pad extending forward from the filling member, and a hard block completely inserted into the filling member; The filling element has a substantially hexagonal block shape and a substantially stepped shape, and the filling element is made of an elastic material selected from the group consisting of foamed plastic, rubber or Cotton for comforting the sitting device, the sum of the area of the beveled surface of the filling element and the area of the thin pad is greater than the total area of the user's buttocks, thighs and knees for the user to sit on The user's body part will not touch the floor plane outside the seated device when the user is folded in a sitting position and sits completely on the seated device; the hard block is disposed inside the filling element The hard block is made of a non-elastic material selected from wood, polystyrene foam or hard rubber, and the hard block can withstand the weight of an adult without deformation. The hard block is designed such that a height of the hard block can fill a distance from a lowest point of the user's tibia to a highest point of the ischial tuberosity, the lumps having a front end height that is greater than the lowest point of the user's tail vertebrae To the user's cheekbones The distance between the lowest points of the nodule enables the hard block to closely maintain the user's pelvis and humerus in an upright and symmetrical posture, and from the top to the bottom according to an anatomical plane, at which the hard block is substantially one The stepped shape ensures that each part of the user's pelvis, tail vertebrae and ischial bone can be supported to maintain the pelvis and humerus upright and symmetrical, thereby further preventing spinal diseases in the cervical, thoracic and lumbar spine.

In order to properly use the seated device, the user must sit on the folded seat with a pair of legs, the user's buttocks will be above the highest part of the filling element, and the user's thighs will lean against the beveled surface of the filling element. The left and right calves of the user must be placed flat on the inside of the thin pad and overlap along one long side of the thin pad, and the right lower leg is placed on the left lower leg. Conversely, the user can also sit on a pair of legs, also known as a lotus sitting position. Importantly, the user has to adjust their buttocks so that their tibia and tail vertebrae are lifted up from the top of the lumpy, while the user's ischium remains close to the anterior side of the lumps. In this way, the user's pelvis will always remain locked in the middle position, so that the user can maintain an upright sitting posture from the neck to the waist. The user's head, neck and waist, from the head to the middle point of the spine to the middle point of the pelvis will be aligned in a straight line, thus preventing spinal diseases caused by false sitting posture, such as cervical, thoracic and lumbar diseases. If the filling element lacks a hard block that is fully inserted therein (as described above), the user's pelvis will tilt and may deform at will, resulting in poor sitting posture causing degenerative wear and tear on the spine.

The present invention can be better understood by referring to the drawings and the description of the embodiments. The technical content and detailed description of the present invention are as follows: FIG. 1 is a pre-prevention according to a preferred embodiment of the present invention. Spine disease 2 is a schematic view of the right side of the seat device according to FIG. 1; FIG. 3 is a schematic cross-sectional view of the seat device according to FIG. 1 taken along line A-A' of FIG. 2; Figure 4 is a schematic cross-sectional view of the sitting device according to Figure 1 taken along line BB' in Figure 2; Figure 5 - Figure 7 is a schematic view showing the state of use of the sitting device of the present invention; and 8a Fig. 8c is a schematic diagram of the labor-saving sitting posture, causing the spine to seriously deplete the sitting posture, and causing the spine to degenerate and dissipate the sitting posture.

The present creation provides a sitting device for a user to sit on a flat surface.

The sitting device allows the user to maintain a straight sitting posture by preventing the hunchback phenomenon of the head, neck, waist or the curvature of the spine by maintaining the pelvic position and an intermediate position.

According to a preferred embodiment of the present invention, as shown in FIGS. 1-5, the seat device 100 as shown in FIG. 1 includes a filling member 200 and a thin pad extending forward from the filling member 200. 300, and a hard block 400 that is fully inserted into the filling element 200. As seen from the left side surface 202L of the filling element 200, as shown in FIG. 1 or by the right side surface 202R of the filling element 200, as shown in FIG. 2, the filling element 200 has a substantially six-sided appearance. The filling member 200 is made of an elastic material selected from the group consisting of foamed plastic, rubber or cotton for making the seat device 100 comfortable when sitting. The beveled surface 201 of the filling element 200 is wavy to conform to ergonomics to ensure greater comfort for the user when riding. The area of the beveled surface 201 of the filling element 200 is thin The area of the pad 300 is larger than the total area of the user's buttocks, thighs, and knees for the user to sit on, and when the user is folded in a sitting position and sits completely on the seated device 100, the user The body part will not come into contact with the flat floor outside the seated device 100. The hard block 400 is made of a non-elastic material selected from the group consisting of wood, polystyrene foam and hard rubber. The hard block 400 has a substantially stepped shape and has a tolerance to the weight, so that the hard block 400 can withstand the weight of an adult without deformation, and is designed such that a height H of the hard block 400 corresponds to the lowest point of the user's tibia. The distance between the highest points of the ischial tuberosity, as shown in Fig. 3, the front end surface 403 of the hard block 400 is the height H, which is greater than the distance between the lowest point of the user's tail vertebra and the lowest point of the user's tibial tuberosity. The hard block 400 maintains the distance between the tibia and the tail vertebrae in more than two pelvic ischial nodules to correspond to the height H, and assists the tail vertebrae to remain at a higher position than the ischial tuberosity, so that the hard block 400 can be tightly fixed to the user. The pelvis and tibia maintain an upright and symmetrical posture and ensure that the pelvis and tibia remain upright and symmetrical. And according to the height H of the hard block 400 and from the top to bottom cross-sectional ratio, the hard block 400 has a substantially stepped shape to avoid a situation in which the spine is hunched, bent or deformed when sitting directly on the hard floor. The hard block 400 is disposed inside the soft filling member 200 and has a size approximately equal to the buttocks of an adult body. The hard block 400 is fully inserted into the highest portion of the filling element 200, and the filling element 200 and the hard block 400 each have a flat bottom surface (not shown) to ensure overall stability of the device.

According to Figures 5-7, in order to properly use the sitting device 100, the user has to sit on a pair of legs in a folded sitting position, and the user's buttocks will be above the highest portion T of the filling member 200, such as the third As shown in Figures 6-7, the user's thigh 600 rests against the beveled surface 201 of the filling element 200, and the user's left and right lower legs must lie flat on the inside of the thin pad 300 and along the length of the thin pad. Side L Overlap, as shown in Figure 2, and with the foot of one leg approaching the knee of the other leg. Conversely, the user can also sit on the sitting device 100 with a pair of legs in a sitting position, also referred to as a lotus sitting position, as shown in FIG. Importantly, the user has to adjust his or her hips such that the tibia is supported upwardly by the top 401 of the lumpy 400, while the user's tail vertebra 500 rests in a planar region 402 of the lumpy 400, and The user's ischial bone remains close to the front end face 403 of the hard block 400.

In this way, the user's pelvis will always remain locked in the middle position, so that the user can always maintain a correct sitting posture to avoid spinal diseases caused by wrong sitting posture, such as cervical, thoracic and lumbar diseases. If the filling element 200 lacks the hard block 400 (described above) that is fully inserted therein, the user's pelvis will be tilted arbitrarily, causing asymmetry in the tibia, while the tail vertebrae and the spine will be distorted, causing hunchback and loss of the spine. The natural curve that should have been.

Those skilled in the art can understand various changes that can be made according to the present embodiment without departing from the spirit of the present invention. Therefore, it is obvious that the implementations listed are not intended to limit the present invention, but are intended to cover modifications made in the spirit and scope of the present invention, as defined by the scope of the appended claims.
