Description

TECHNICAL FIELD

[0001] The utility model relates to a stretcher, especially a thoracic cage stretcher. BACKGROUND

[0002] The stretching of the thoracic cage is a three-dimensional movement, and the best stretching effect should be combined with the "spine coupling movement", that is, the stretching of the whole spine. If the spine is supposed to stretch from the sacrum to the head, but only stretches a certain segment of the thoracic vertebrae, such stretching is not very friendly to the joints, and the thoracic cage stretching effect is also limited. Therefore, the support surface of the stretching device should have a three-dimensional stretching space in length, upward and downward curvature, and left and right directions.

[0003] The thoracic cage stretching also needs to consider the angle of inclination of the sternum, that is, the horizontal position of the xiphoid process of the sternum is not higher than the horizontal position of the manubrium. At this angle, the scapula is retracted and sunken, and the ribs are opened. That is, the angle between the thoracic vertebrae segment and the horizontal plane should be within the range of 30°-80° counterclockwise.

[0004] The thoracic cage stretching also needs to stretch the relevant muscles such as the pectoralis major muscle and the anterior beam of the deltoid muscle, so the height of the device should ensure that the arms can freely stretch without touching the ground on both sides of the body.

[0005] In addition, due to the attachment of muscles and fat, the spine process is in a groove in the middle of the back. If you want to achieve the "spine coupling movement" when opening the thoracic cage and stretching the spine, the spine needs to be supported correspondingly to prevent the middle spine from collapsing, which disrupts the coupling movement of the joints, affects the thoracic cage stretching effect, and causes unnecessary stress on the skeletal joints.

[0006] The backrest of the prior art does not have a three-dimensional stretching space in length, a 30°-80° inclination angle of the thoracic vertebrae segment, and a left and right direction of the spine and thoracic cage, and the arms do not have enough stretching space in height. There is no related structure to accurately support the spine groove, resulting in shoulder raising, insufficient stretching of the thoracic cage, or poor and inaccurate results.

[0007] In order to solve the above technical problems, the utility model adopts the technical scheme: a thoracic cage stretcher, comprising a backrest and a head pad, the backrest and the head pad are adjacent, one end of the backrest to the other end forms an arc, and the angle between the thoracic vertebrae segment and the ground in the arc is 30°-80° counterclockwise, and there is a three-dimensional stretching space of the spine and the thoracic cage in the left and right directions of the backrest.

[0008] In order to solve the above technical problems, the utility model adopts the technical scheme: a thoracic cage stretcher, comprising a backrest and a head pad, the backrest and the head pad are adjacent, one end of the backrest to the other end forms an arc, and the angle between the thoracic vertebrae segment and the ground in the arc is 30°-80° counterclockwise, and there is a three-dimensional stretching space of the spine and the thoracic cage in the left and right directions of the backrest.

[0009] Further, the support profile includes a main body in contact with the ground and a first support leg and a second support leg extending upward from both free ends of the main body, respectively, the free end of the first support leg is connected to a foot pedal of the footrest, and the top of the second support leg is connected to a seat surface of the seat.

[0010] Further, the seat surface is concave and upward from one side connected to the backrest to the other free side.

[0011] Further, the backrest includes a raised keel adapted to support the human spine.

[0012] Further, if the backrest includes a supine board, the raised keel is integrally formed in the middle of the left and right width directions of the supine board and extends in the same direction as the length direction of the supine board.

[0013] Further, the large support leg extends upward and its head forms a first clamping ear plate and a second clamping ear plate which are independent of each other and are spaced apart by an avoidance gap, and the first clamping ear plate is fastened and connected to the fastening block of the backrest by a fastening bolt.

[0014] The head of the large support leg extends to one side to form an extended connection block located directly below the headrest, and the middle of the extended connection block is provided with a through gap.

[0015] Further, the headrest includes a headrest and an adjustment connection block connected to the bottom of the headrest, the middle of the adjustment connection block is provided with a clamping groove matched with the through gap, the clamping groove is connected to the adjustment plate piece by a fastening bolt, and the free end of the adjustment plate piece is movably connected in the through gap by a latch in a manner of changing its own position.

[0016] Further, the front of the headrest forms a support groove that fits the human head.

[0017] Further, the position of the adjustment connection block close to the backrest side is limitingly connected to the second clamping ear plate by a fastening bolt.

[0018] A thoracic expander, compared with the prior art, is more ergonomic, especially the position where the arc-shaped support of the length extension of the backrest abuts against the middle thoracic vertebrae has an angle of 30°-80° counterclockwise with the ground, and the active space for three-dimensional stretching of the spine and thorax in the left and right directions of the backrest can make the whole spine stretch three-dimensionally while opening the thorax, and the raised keel can resist the spinous process of the spine, so that the stretching action is more accurate, in addition, the lifting of the overall height of the device makes the arms stretch well and further stretch the related muscles, which is further beneficial to opening the thorax.

DETAILED DESCRIPTION

[0024] The utility model will be explained in further detail below in combination with the drawings and specific embodiments.

[0025] As Figures 1-4 Commonly shown, the embodiment about thoracic expander, including support section bar 1, big supporting leg 2, support section bar 1 is supported with seat part 4, seat part 4 is connected with the backrest part 5 that is supported on the other side through big supporting leg 2, big supporting leg 2 still supports the headrest part 6 adjacent with backrest part 5 and the activity adjustment, the left and right direction of backrest part 5 is left with the activity space of three-dimensional extension of spinal column and thoracic, preferably, backrest part 5 still carries out in the way of supporting human spinal column groove, in addition to this, it can be understood that, the present application is in height when the arm is stretched on the both sides of the body and is not limited because of touching the ground, so as to stretch the relevant muscle to reach more fully thoracic extension, it still needs to be stated that, the embodiment carries out the support to the foot, hip, back, head of human body, reaches the effect of thoracic extension, emphatically speaking, the embodiment highlights the support of the back of human body and carries out mechanism design, and then makes the thoracic extension effect better.

[0026] Preferably, the support profile 1 also supports a footrest part 3 independent of the seat part 4, the support profile 1 comprising a main body in contact with the ground and a first support leg 7 and a second support leg 8 extending upwardly from both free ends of the main body respectively, the free end of the first support leg 7 being connected to a footboard 9 of the footrest part 3, and the top of the second support leg 8 being connected to a seat surface 10 of the seat part 4, in actual production, the height of the first support leg 7 and the second support leg 8 can be set according to individual differences in customization requirements, which is not limited in the present application.

[0027] On this basis, further explanation of the height dimension, in order to make the arm not touch the ground, in actual production, the height of the large support leg 2, the first support leg 7 and the second support leg 8 arranged in the height direction need to be adjusted, the specific height parameters of the three are implemented in a way to meet the individual differences, the present application does not limit the specific height of the above three, only to show the effect reached by lifting the large support leg 2, the first support leg 7 and the second support leg 8.

[0028] In order to stabilize the human body when it is stretched out to stretch the spine and chest, the seat surface 10 is concave and upward from the side connected to the backrest part 5 to the other free side, so as to resist the ischium, which is more conducive to ischium bearing and preventing the body from sliding down during stretching than the traditional flat seat surface, and is conducive to indirectly strengthening the stretching effect.

[0029] The distance between the seat surface 10 and the footboard 9 and the width of the footboard 9 can be selected according to comfort.

[0030] In the embodiment, the large support leg 2 extends upwardly and its head forms a first clamping ear plate 11 and a second clamping ear plate 12 independent of each other and spaced by an avoiding gap 13, the first clamping ear plate 11 is fastened and connected to a fastening connecting block 17 of the backrest part 5 through a fastening bolt 14, thus completing the connection and arrangement of the backrest part 5 and the large support leg 2, and strengthening the stability of the backrest part 5.

[0031] Preferably, the head of the large support leg 2 extends to one side to form an extended connecting block 23 located directly below the headrest part 6, and a gap 24 is formed in the middle of the extended connecting block 23.

[0032] Furthermore, the headrest 6 includes a headrest 18 and an adjustment connecting block 20 connected to the bottom of the headrest 18. The adjustment connecting block 20 has a groove 21 in the middle that matches the passage gap 24. The groove 21 is connected to an adjustment plate 22 by a fastening bolt 14. The adjustment plate 22 is curved. The free end of the adjustment plate 22 is movably connected to the passage gap 24 by a pin 25 to change its position. It can be understood that the adjustment plate 22 has several adjustment through holes (not shown in the figure). The pin 25 passes through and connects to the adjustment connecting block 20. When the pin 25 passes through the adjustment through hole on the adjustment plate 22, the tilt position of the headrest 18 is locked. Changing the pin 25 through different adjustment through holes on the adjustment plate 22 changes the tilt position of the headrest 18, which is beneficial to enhance the head fit and extension requirements of different people. It can also be understood that changing the tilt position of the headrest 18 also changes the height of the headrest 18. This is hereby explained.

[0033] Furthermore, the front of the headrest 18 forms a support groove 19 that conforms to the human head. When in use, the support groove 19 helps to improve the comfort of the human head, making the head fit more closely, and the concavity of the support groove 19 can prevent the head from becoming unstable in the left and right directions.

[0034] Furthermore, the position of the adjusting connecting block 20 near the backrest 5 is limited and connected to the second clamping ear plate 12 by the fastening bolt 14. Therefore, when the headrest 18 changes its tilt position, the connection point between the adjusting connecting block 20 and the second clamping ear plate 12 is the tilt rotation point of the headrest 18.

[0035] Example 1

[0036] Based on the above, such as Figure 4 As shown, the backrest 5 of Embodiment 1 includes a raised keel 16, which is adapted to support the human spinal groove. In this embodiment, one end of the raised keel 16 is directly connected to the seat 10, and the other end is connected to the first clamping ear plate 11 through an integrally formed fastening connecting block 17. This arrangement allows the human rib cage, especially the costochondral joint, to extend and open more fully while the raised keel 16 is adapted to support the human spinal groove, making it suitable for people who have a higher demand for rib cage extension.

[0037] Example 2

[0038] like Figures 1-3As shown in the drawings, the difference between the embodiment 2 and the embodiment 1 is that the backrest part 5 of the embodiment 2 comprises a supine plate 15, and the convex keel 16 is integrally formed in the middle of the supine plate 15 in the width direction and extends in the length direction of the supine plate 15, and it is necessary to point out that in this structure, one end of the supine plate 15 is directly connected to the seat surface 10, and the other end is connected to the first clamping ear plate 11 through the fastening connecting block 17 integrally formed on the back surface of the supine plate 15, and the supine plate 15 is used to provide support for the back of the human body, and the setting makes the convex keel 16 adapt to support the anterior spinal groove of the human body under the premise of being more conducive to the safe use of novice groups, in addition, the width of the supine plate 15 is not greater than the shoulder width of the human body, so as to avoid limiting the stretching of the arms.

[0039] The commonalities of the above two embodiments are that in order to achieve better thoracic opening and stretching effect, the angle between the position where the length-extended arc-shaped support of the backrest part abuts against the thoracic spine segment and the ground is counterclockwise 30°-80°, and the curvature of the lumbar spine segment is selected according to the actual situation, that is, when the user uses the structures disclosed in the above two embodiments and the thoracic spine segment of the human body abuts against the backrest part 5, the angle between the position where the thoracic spine segment abuts against and the ground is counterclockwise 30°-80°, and in this state, the best thoracic opening and stretching effect can be achieved. The measurement method of the counterclockwise angle of the thoracic spine segment is that the counterclockwise angle between the connecting line of the positions where the 12th thoracic vertebra and the 1st thoracic vertebra respectively abut against the backrest part and the horizontal plane.

[0040] The thoracic expander disclosed in the present application is more ergonomic than the prior art, and in particular, the angle between the position where the length-extended arc-shaped support of the backrest part abuts against the thoracic spine segment and the ground is counterclockwise 30°-80°, and the combined three-dimensional stretching space given to the left and right directions of the spine and the thorax can make the whole spine three-dimensionally stretch while opening the thorax, and through the convex keel, the spinous process of the spine can be resisted, and the stretching movement is more accurate, in addition, the lifting of the overall height of the device makes the arms stretch well and further stretch the related muscles, which is further conducive to opening the thorax.

[0041] The above-mentioned embodiments are not a limitation on the present application, and the present application is not limited to the above examples, and the changes, modifications, additions or replacements made by the person skilled in the art within the technical solution range of the present application also belong to the protection scope of the present application.
