Description

Technical Field

[0001] The present invention relates to a traction device, in particular to a traction device that applies traction forces by the upper limbs and lower limbs, and this traction device is mainly used for lumbar traction and physical exercise. Background Art

[0002] For patients with mild lumbar disc herniation, traction is the best, simplest, and most effective treatment method with rapid and significant curative effects. For people without lumbar disc herniation, frequent lumbar traction can not only prevent lumbar disc herniation but also exercise the body. Pulling a single bar in an upright position has a traction effect on the lumbar spine, but the traction force on the lumbar spine is less than half of the pulling force on the arms, so the traction effect is not good. Currently, traction beds are commonly used for traction. When in use, a person lies on the traction bed, and the waist and armpits are tied with straps. The traction bed applies a traction force to the lumbar spine of the person through the straps. The disadvantages of the traction bed are: complex structure, troublesome to use, relatively high production cost, and the straps tying the waist and armpits of the person make people uncomfortable. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the existing traction bed, such as complex structure, troublesome to use, relatively high production cost, and the straps tying the waist and armpits of the person making people uncomfortable, and provide a traction device that applies traction forces by the upper limbs and lower limbs.

[0004] The technical solution adopted by the present invention is: a traction device that applies traction forces by the upper limbs and lower limbs, characterized in that: an upper limb connection device, a traction force transmission device, and a lower limb connection device are provided; when in use, the rear end of the traction force transmission device contacts or is connected to the upper limb connection device; the front end of the traction force transmission device contacts or is connected to the lower limb connection device.

[0005] Explanation 1: The upper limb connection device is used to connect or contact with the upper limbs. For example, when a person grabs the upper limb connection device with both hands during use, the connection between the person's hands and the upper limb connection device is achieved; the lower limb connection device is used to connect or contact with the lower limbs, and the lower limbs include but are not limited to the thighs, feet, and ankle joints. When in use, assuming the user's head is in the east and feet are in the west, the upper limbs apply a westward pressure to the traction force transmission device through the upper limb connection device, and at the same time, the lower limbs apply an eastward pressure to the traction force transmission device through the lower limb connection device. Then, the traction force transmission device has a reaction force on the upper and lower limbs, thereby generating a force for traction of the thoracic and lumbar vertebrae.

[0006] Description 2: The rear end of the traction transmission device is connected to the upper limb connection device, and the front end of the traction transmission device is connected to the lower limb connection device. These two types of connections include fixed connections and detachable connections. A fixed connection means that it cannot be disassembled after connection, or disassembly will cause damage to the parts; a detachable connection means that it can be disassembled after connection and disassembly will not cause damage to the parts.

[0007] The following additional technical features are proposed for the above technical solutions:

[0008] 1. The lower limb connection device includes a flexible member; the flexible member is a flexible cylinder or a flexible sheet or a flexible ring or an openable flexible ring or a flexible belt, or the flexible member is a combination of any two or any three or any four of the flexible cylinder, the flexible sheet, the flexible ring, the openable flexible ring and the flexible belt.

[0009] 2. The lower limb connection device includes a first connecting member and a second connecting member; the first connecting member is one or two transverse tubes or one or two transverse rods; the second connecting member is a flexible member; the flexible member is a flexible cylinder or a flexible sheet or a flexible ring or an openable flexible ring or a flexible belt, or the flexible member is a combination of any two or any three or any four of the flexible cylinder, the flexible sheet, the flexible ring, the openable flexible ring and the flexible belt; the upper limb connection device includes one or two transverse tubes or one or two transverse rods.

[0010] 3. The traction transmission device includes longitudinal parts, and the longitudinal parts are longitudinal tubes or longitudinal rods; let the number of longitudinal tubes be k and the number of longitudinal rods be f, k + f ≥ 1; when k + f ≥ 2, any one longitudinal part is detachably connected to the adjacent longitudinal part.

[0011] 4. The upper limb connection device has one set or two sets; when there are two sets of upper limb connection devices, the first set of upper limb connection device is connected to the rear end of the traction transmission device, and the second set of upper limb connection device is located between the front end and the rear end of the traction transmission device; each set of upper limb connection devices includes one or two transverse tubes or one or two transverse rods.

[0012] Description 3: When a person uses the traction device that applies traction force by the upper and lower limbs, draw a line from the midpoint of the user's head to the midpoint between the user's two feet, and assume that this line is the longitudinal line, and another line perpendicular to this longitudinal line is the transverse line; then the tube or rod whose center line is parallel or coincident with the longitudinal line is the longitudinal tube or longitudinal rod, and the tube or rod whose center line is parallel or coincident with the transverse line is the transverse tube or transverse rod.

[0013] Description 4: In use, the first connecting member is used both for contacting or connecting with the traction transmission device and for connecting with the flexible member; the flexible member is also used for connecting with a person's lower limbs. The flexible member is made of rubber, cotton, hemp, or latex.

[0014] Description 5: If there are two sets of upper limb connecting devices, the second set of upper limb connecting devices is located in the middle area of the traction transmission device, and the first set of upper limb connecting devices is located at the rear end of the traction transmission device. When using the first set of upper limb connecting devices, the force exerted by both hands is a pulling force because the first set of upper limb connecting devices is located behind the head; it is relatively easy to pull using the pulling force of both hands. When using the second set of upper limb connecting devices, the force exerted by both hands is a pushing force because the second set of upper limb connecting devices is located near the person's waist.

The same methods apply to "installing a horizontal pipe on each of the two horizontal short rods of the T-shaped frame".

[0035] Advantageous effects: When in use, a person lies supine on the bed. The person's upper limbs are connected to the upper limb connecting device, and the person's lower limbs are connected to the lower limb connecting device. The upper and lower limbs simultaneously apply pressure to the traction transmission device, and then the traction transmission device has a reaction force on the upper and lower limbs, thereby performing traction on the lumbar spine. This traction device has a simple structure, low production cost, convenient use, and good traction effect. The magnitude of the traction force is determined by the magnitude of the force applied by the person's upper and lower limbs to the traction transmission device, and the user can flexibly control it.

Detailed implementation mode

[0081] The following is combined with Figures 1 to 44 to further illustrate the present invention:

[0082] Figures 1 to 2 The traction device with traction forces applied by the upper and lower limbs is characterized in that: the lower limb connecting device includes a first transverse rod and two sets of second connecting parts; each set of the second connecting parts includes a base body and a first flexible cylinder; the base body includes two boards; the first flexible cylinder is surrounded by a rectangular cloth, and the two end regions of the rectangular cloth are installed between the two boards and fixed by bolts and nuts; connection holes are provided in the middle regions of the two boards and the regions of the rectangular cloth in contact with the middle regions of the boards.

[0083] Both the left and right sections of the first cross bar are threaded; the left section of the first cross bar is connected to the base of a set of second connectors, with a part of the left section of the first cross bar located in the connection hole of the base. There is a nut on each side of the base to tighten the base so that it cannot move relative to the first cross bar; if there are two nuts on each of the left and right sides of the base, the two nuts on the left are pressed against each other, the two nuts on the right are pressed against each other, and there is a small gap between the nuts and the base, then the base can only rotate around the first cross bar.

[0084] The right section of the first cross bar is connected to the base of another set of second connectors in the same way.

[0085] The traction transmission device is the first longitudinal bar, and its front end is welded integrally with the middle section of the first cross bar.

[0086] The upper limb connection device is the second cross bar, and its middle section is welded integrally with the rear end of the first longitudinal bar.

[0087] The first cross bar, the first longitudinal bar, and the second cross bar form an "I" shape; the three "bars" can all be replaced by three "tubes".

[0088] When in use, a person lies in bed. One cylinder is sleeved on the left thigh, and the other cylinder is sleeved on the right thigh. The two thighs are in a vertical state, the soles of the feet are against the wall, and the calves are in a horizontal state; when both hands hold the handle and apply pressure to the oval rod or oval tube, the oval rod or oval tube applies pressure to the cross bar, and the cross bar applies force to the two cylinders through two plates, thereby applying pressure to the two thighs, and finally generating traction on the lumbar and thoracic vertebrae; or when in use, the feet are straightened, one cylinder is sleeved on the left foot, and the other cylinder is sleeved on the right foot, then the two cylinders apply pressure to the insteps of the two feet respectively, and finally generate traction on the lumbar and thoracic vertebrae.

[0089] Explanation 11: The two end regions of the rectangular cloth-like object include its A-end region and B-end region; if the rectangular cloth-like object is unfolded and placed on the table, it has an A-end and a B-end in the length direction; then its A-end region refers to the region on the rectangular cloth-like object that extends a certain distance from the A-end towards the B-end, and this distance is determined according to the actual situation; its B-end region refers to the region on the rectangular cloth-like object that extends a certain distance from the B-end towards the A-end, and this distance is determined according to the actual situation.

[0090] Figures 3 to 4 The difference between the said set of second connectors and Figures 1 to 2 the second connectors in is that the main surfaces of the two plates of the base are parallel to the first cross bar, and there are connection ears on the base. When in use, the first cross bar is inserted into the connection ears, then the first cross bar does not need to be machined with threads.

[0091] Figure 5 The base body of a set of second connectors shown is a board; the cylinder is formed by a rectangular cloth-like material. After the two ends of the rectangular cloth-like material are joined together, the two ends of the rectangular cloth-like material are joined to the board; connection holes are provided in the middle area of the board and the area of the rectangular cloth-like material that contacts the middle area of the board for connection to the first type of cross bar.

[0092] Figure 6 A set of second connectors shown is connected with Figure 5 The difference is that one end of the rectangular cloth-like material is joined to one main surface of the board, and the other end of the rectangular cloth-like material is joined to the other main surface of the board; connection holes are provided in the middle area of the board and the area of the rectangular cloth-like material joined to this middle area for connection to the first type of cross bar.

[0093] Figures 7 to 8 A set of second connectors shown is composed of a flexible sheet and flexible bands. Six flexible bands are installed on the flexible sheet; the flexible sheet is in a tile shape and is made of rubber or latex or cotton cloth. When in use, Figure 7 Four flexible bands on both sides in Figure 7 are used for connection to various cross bars or various cross tubes, that is, a certain cross bar or cross tube is tied with four flexible bands;

[0094] Figures 9 to 10 A set of second connectors shown includes a base plate and flexible bands. The flexible bands are installed on the base plate; the number of flexible bands is one or more;

[0095] The shape of the base plate is in the shape of a shoe sole and is adapted to the shape of the foot;

[0096] The bottom surface of the base plate is provided with a first type of connection ear for connection to various cross bars or various cross tubes. For example, when in use, the first type of cross bar is located between two first type of connection ears.

[0097] The band is used to tie on the thigh or on the instep, heel and ankle joint.

[0098] Figures 11 to 12 A set of second connectors shown is connected with Figures 9 to 10 The difference between the second connectors shown and

[0099] Figures 13 to 14The main body of a set of second connectors shown is a slipper, and each slipper includes a sole and an upper; two flexible straps are provided on each upper for connecting with the user's ankle; a second connecting ear is provided on the bottom surface of each sole for connecting with various cross bars or various cross tubes; when in use, the user puts their feet into the slippers.

[0100] Figures 15 to 16 A set of second connectors shown and Figures 13 to 14 The difference between the second connectors shown is that the main body of each set of second connectors is a shoe, that is, the upper has a part that encloses the heel.

[0101] Figures 17 to 18 A set of second connectors shown consists of an openable and closable flexible ring and six flexible straps. The openable and closable flexible ring and the flexible straps are all made of flexible materials such as rubber, latex, and cotton cloth. Two such second connectors are provided for a set of traction devices. When in use, the two flexible straps on both sides of this second connector are connected to a certain cross bar or a certain cross tube; the openable and closable flexible ring is put on the user's ankle, and then the four flexible straps at the front of the openable and closable flexible ring are used to tie the two ends of the openable and closable flexible ring to make the openable and closable flexible ring closed; otherwise, when in use, the openable and closable flexible ring will slip off the foot after being loosened by the force.

[0102] Figures 19 to 20 A set of second connectors shown and Figures 17 to 18 The difference between the second connectors shown is only that the closing methods of the two are different. The former relies on the pulling force of the four flexible straps to maintain the closed state of the openable and closable flexible ring when stressed; the latter uses the four flexible straps to tie the two ends of the openable and closable flexible ring tightly, and relies on the friction between the four flexible straps and the openable and closable flexible ring to maintain the closed state of the openable and closable flexible ring when stressed.

[0103] Figures 21 to 23 A set of second connectors shown has a tile-shaped plate, a tile-shaped soft body is installed in the groove of the tile-shaped plate, and a first connecting ear is provided on the convex surface of the tile-shaped plate. This kind of connector can be used for connecting with the thigh or the instep. Using this second connector to replace Figures 1 to 2 the second connector in, when in use, a person lies in bed, the groove of a tile-shaped soft body is attached to the left thigh, the groove of a tile-shaped soft body is attached to the right thigh, the two thighs are in a vertical state, the soles of the feet are against the wall, and the calves are in a horizontal state; the left end and the right end of the first cross bar are respectively inserted into the holes of a connecting ear; both hands hold the second cross bar and apply pressure to the first longitudinal bar, then the first longitudinal bar applies a reaction force to the two thighs and the two hands, so as to perform traction on the lumbar vertebra and the thoracic vertebra. When this second connector is connected to the instep, the user lies supine in bed, the thighs and calves are both placed flat, the toes are hooked forcefully in the direction of the head, and at the same time both hands pull or press the second cross bar to apply pressure to the first longitudinal bar.

The first connecting member of the lower limb connection device of the tractor is two third transverse tubes. The upper limb connection device of the tractor has two sets: one is two second transverse tubes. When in use, the user's two hands grasp a third transverse tube each and push it toward the sole of the foot with force, and the force used is a thrust; the other is a second transverse rod.
