Description

Exercise Equipment For Stretching The Spine

The present invention relates to an exercise device for stretching the spine, and more particularly, to an exercise device for stretching the spine capable of performing exercises including stretching or back exercise and correcting posture.

In general, the spine constitutes the main skeleton of a person from the neck, back, waist, hips, and tail.

The vertebrae are semicircular joints sandwiched between the vertebrae from the cervical vertebrae to the lumbar vertebrae, and there is a cartilage plate in contact with the vertebrae between each joint, and is surrounded by elastic annular fibers around the circumference of the circle. The inner center contains a soft sap.

Spinal disc disease, commonly referred to as a herniated nucleus pulposus, occurs in the nucleus pulposus and annulus fibrosus located between the vertebrae and the vertebrae. The root cause of this vertebral disc disease is that the vertebral disc is compressed or damaged by pressure due to upright living and forward flexion activity.

That is, the nucleus pulposus between the vertebrae and the vertebrae protrude from an excessive load or impact from the outside and the nerve root is compressed. Spinal disc disease occurs to the extent that normal activities cannot be performed in this state.

In the modern industrial society, people spend more time bending forward to work, and when working on a computer in the office or living in the wrong posture in the classroom for a long time, the spine, neck, and shoulders that extend from the pelvis to the head are bent forward, and sometimes the pain is caused by bending left and right. sometimes it causes.

In particular, office workers, students, and housewives who sit for a long time use computers for a long time or due to incorrect posture, the spine and lower back are bent or withdrawn, and the posture is not correct. cause disease. As a person's spine gets older, there may be an abnormality in the intervertebral disc, which can cause spinal diseases, but most of them occur due to an abnormal life. In the case of children and adolescents, when there is an abnormality in the spine, pressure is applied to the growth plate, and accordingly, the secretion of growth hormone is not smooth and growth promotion is inhibited.

Therefore, it is desirable to straighten the spine and strengthen the muscles of the back by stretching the whole body from the back using a medical aid that corrects the spine while lying down and strengthens the muscular strength of the back.

That is, in the first curved portion 152 , the inclined surface on the front side with respect to a1 corresponding to the vertex of the parabola was formed more gently than the inclined surface toward the curved groove portion 156 .

This is to increase the stretching effect by being supported on the inclined surface where the waist, back, side, etc. are formed high in a state in which the buttocks and the like are positioned in the curved groove portion 156 .

Subsequently, in the second curved portion 154 , the inclined surface facing the curved groove portion 156 may be gentler than the rearward inclined surface.

The second curved portion 154 may be formed to have a shorter length and a lower height than the first curved portion 152 in the overall length.

Based on the vertex a2 of the parabola, the slope of the rear side may be steep, and the slope toward the curved groove portion 156 may be formed relatively gently.

The part with a gentle slope relative to a2 is to allow the user's thighs to be supported naturally.

And the auxiliary cushion 200 is selectively positioned on the body cushion 100 to help the user's stretching, and may be composed of the memory foam 110 and the outer shell 120 like the body cushion 100 .

Since it is the same material as the memory foam 110 and the outer shell 120 of the body cushion 100, a separate description will be omitted.

The auxiliary cushion 200 forming a predetermined shape with the memory foam 110 and the outer shell 120 is a flat auxiliary bottom surface 210 to be supported on the bottom surface, and continues in a right angle direction from the auxiliary bottom surface 210. The auxiliary side surface 220 having a predetermined height and the auxiliary curved upper surface 230 formed to protrude while having a gentle inclination angle in a shape corresponding to the curved groove portion 156 of the body cushion 100 are included.

The auxiliary bottom surface 210 has a predetermined area in a rectangular shape, and an anti-slip pad 132 may be installed therein.

When the auxiliary cushion 200 is described with reference to the side view of FIG. 5 , it may be formed by changing the inclined surface based on a3 corresponding to the vertex of the parabola.

One or more auxiliary cushions 200 may be provided on the main cushion 100 .

On the other hand, since the auxiliary cushion 200 is formed separately from the main cushion 100, a receiving part 116 is provided in the main cushion 100 for storage and movement.

Referring to FIG. 7 , a receiving part 116 corresponding to the shape of the auxiliary cushion 200 is provided on the bottom surface of the memory foam 110 of the body cushion 100 to position the auxiliary cushion 200 , and a zipper 134 . is used to couple the anti-slip pad 132 .

Since two or more storage units 116 can be formed, the auxiliary cushion 200 provided with two can also be accommodated.

And in another embodiment of the present invention, a heating means may be installed in the memory foam 110 of the body cushion 100 in the exercise equipment for stretching the spine.

The heating means includes a heat insulating member 300 installed along the upper surface of the memory foam 110 of the body cushion 100, a heating member 310, a heating wire 320, a heating wire ( The power supply unit 330 for supplying power to the 320, the temperature sensing unit 340 for sensing the temperature of the heating member 310, and the power supply unit 330 according to the sensing signal applied from the temperature sensing unit 340. It may include a control unit 350 that turns on/off.

An upper groove 118 is formed on the upper surface of the memory foam 110 to a predetermined depth, and the upper groove 118 may be formed in a zigzag pattern along an upper area of the memory foam 110 .

A semicircular heat insulating member 300 is installed along the upper groove 118 , and the heat insulating member 300 blocks heat transferred to the memory foam 110 to prevent damage to the memory foam 110 and prevent fire. can be prevented in advance.

The heat insulating member 300 may be installed in a shape such as a hemispherical pipe having an upper opening, and inserted and seated along the upper groove 118 .

And the heating member 310 is installed on the upper portion of the heat insulating member (300).

The heating member 310 may preferably be a metal material such as copper having excellent heat conduction, and constitute a hemispherical portion 312 that is installed in surface contact with the opened insulating member 300 , and is integrally connected to the hemispherical portion 312 . It may be composed of a flat heating plate 314 .

The heating plate 314 may be installed to form the same plane as the memory foam 110 .

Next, the heating member 310 is provided with a heating wire 320 that generates heat according to the supply of power to the inside.

The heating wire 320 is installed between the hemispherical part 312 of the heating member 310 and the hemispherical insulating member 300, and one end is electrically connected.

The heating wire 320 may use a copper wire or an alloy wire mixed with nickel and chromium.

The controller 350 may be a concept including at least one processor, a memory, and a storage device.

Here, the processor may execute a program command stored in a memory and/or a storage device. The processor may mean a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which the methods according to the present invention are performed. The memory and the storage device may be comprised of a volatile storage medium and/or a non-volatile storage medium. For example, the memory may be configured as read only memory (ROM) and/or random access memory (RAM).

The control unit 350 may be electrically connected to at least one of the temperature sensing unit 340 and the power supply unit 330 .

The temperature sensing unit 340 may be installed on the heating member 310 , and when the temperature rises above the reference set value by sensing the temperature, the power of the power supply unit 330 is turned off to be applied to the heating member 310 . will cut off the power.

For example, the controller 350 may compare the measured value (eg, the temperature value of the heating member) obtained through the temperature sensing unit 340 with a preset reference value L (or “reference temperature value”). The reference value L may be a set temperature value. For example, the reference value L may correspond to a temperature of 40°C.

When the measured value of the temperature sensing unit 340 exceeds the reference value (L), the power is cut off, and when the value is less than the reference value (L), the power is turned on to supply power to the heating member 310 .

On the other hand, when a heat generating means is installed in the memory foam 110 of the body cushion 100 according to another embodiment, a flame retardant composition for expandable polystyrene may be added thereto.

The flame retardant composition is liquid sodium silicate 40-60 wt%, silica sol 10-15 wt%, liquid antimony pentoxide compound 5-10 wt% and liquid phosphate compound 5-10 wt%, and aluminum hydroxide 5-20 wt% foamable poly A flame retardant composition for styrene can be provided.

Among the flame retardants applied to expandable polystyrene, the most used raw material is liquid sodium silicate (Na2O·SiO2), and in the present invention, silica sol, liquid antimony pentoxide compound, liquid phosphate compound, and aluminum hydroxide are mixed with liquid sodium silicate. do.

Silica sol significantly reduces moisture absorption and whitening by making the crystal phase longer, and makes the glass more robust. It strengthens, and the liquid phosphate compound acts to stabilize the sol and promote flame retardancy.

In addition, aluminum hydroxide is compounded with a sol compound as an inorganic powder flame retardant to enhance flame retardancy.

The liquid sodium silicate preferably has a weight ratio of sodium oxide (Na2O) and silicon dioxide (SiO2) of 1:3 to 5, and a pH of 12.5 to 13.5. That is, since the weight ratio of sodium oxide (Na2O) and silicon dioxide (SiO2) in liquid sodium silicate is important in terms of viscosity and specific gravity, by setting the ratio to 1:3 or more, it can be adjusted to an appropriately low viscosity, and oxidation By lowering the sodium (Na2O) content, the whitening phenomenon can be prevented, and by setting it to 1:5 or less, the viscosity can be adjusted to an appropriately high viscosity, and the sodium oxide (Na2O) content can be appropriately increased to exhibit excellent flame retardancy. will be.

Moreover, when the pH is set to 12.5 to 13.5, it is advantageous for promoting natural curing. This liquid sodium silicate is included in an amount of 40 to 60 wt % based on the total weight of the flame retardant composition, and if it is less than 40 wt %, the effect of flame retardancy and flame retardancy is reduced, and if it exceeds 60 wt %, the dryness and permeability are reduced, and natural curing becomes difficult and drying In case of natural curing, flame retardant liquid may flow.

The silica sol is not particularly limited as long as it is a silica-based compound in a sol state, but in particular, as a silica-based compound in a sol state, the sodium oxide (Na2O) content is 0.5% or less, considering the prevention of gelation of the flame retardant composition Therefore, it is preferable to use one with a pH of 9.5 to 10.5, and it may be advantageous to use one with a solid content of 25 to 35% in consideration of helping natural hardening and preventing the surface of liquid sodium silicate from slipping. The silica sol is included in an amount of 10 to 15 wt% based on the total weight of the flame retardant composition. If it is less than 10 wt%, the natural curing effect is lowered, and the liquid sodium silicate, which is the main component, is easy to flow in the form of icicles, and if it exceeds 15 wt% The flame retardancy is lowered, and bubbles are generated during drying to coat the surface of the Styrofoam, and the flow phenomenon of the silica sol itself due to the low viscosity occurs.

As the liquid antimony pentoxide compound, an antimony pentoxide colloidal sol prepared by a method for producing an antimony flame retardant improved with antimony pentoxide in a colloidal sol state may be used. Liquid antimony pentoxide compound should not precipitate in a colloidal sol state or separate layers, and the pH is 3.5 to 4.5 to facilitate natural hardening of liquid sodium silicate, and is proportional to the sodium oxide (Na2O) content of liquid sodium silicate. Considering that the compound is formed, it is preferable to use a solid concentration of 20 to 30%. When mixed with liquid sodium silicate, smoke is reduced, a translucent liquid is obtained, and Na2OSb2O51/2H2O compound and SiO2, which are self-extinguishing and have excellent fire resistance, are produced to provide flame retardant and natural curing effects at the same time. When the expandable polystyrene is burned, the flame retardant is present on the surface of the Styrofoam bead in the form of a coating, so the Styrofoam bead is melted during combustion, and only the coated flame retardant is left, forming a honeycomb-shaped flame retardant film to further enhance the flame retardant and flame retardant effect. The antimony pentoxide compound is preferably used in an amount of 5 to 10 wt % based on the total weight of the flame retardant composition, and if it is less than 5 wt %, the flame retardancy and natural hardenability are reduced, and if it exceeds 10 wt %, the flame retardant effect is reduced as an adverse effect.

As the liquid phosphate compound is formed of phosphoric acid and ammonium salt, it is preferable to use a transparent liquid having a pH of 7.5 to 8.5 and a solid concentration of 7 to 15%. This is to improve the flame retardancy by promoting stabilization and sol formation of the phosphorus-based flame retardant in the buffer region of the pH of the composite flame retardant and preventing layer separation or precipitation of the flame retardant composition. It is preferable to use such a phosphate compound in an amount of 5 to 10 wt % based on the total weight of the flame retardant composition, but if it is less than 5 wt %, the effect of promoting sol formation is insufficient, and if it exceeds 10 wt %, it overreacts with liquid sodium silicate to generate a gel .

It is preferable to use aluminum hydroxide having an average particle size of 1.5 µm or less and an apparent specific gravity (bulk density) of 0.5 or less, which is liquid sodium silicate, silica sol, liquid antimony pentoxide compound, and liquid phosphate compound. This is to improve the flame retardancy by mixing well with the mixture of Such aluminum hydroxide contains 5 to 20 wt % based on the total weight of the flame retardant composition, and if less than 5 wt %, the honeycomb-shaped flame retardant film is weak, so melting easily occurs in the burning area. The permeability of the composition is poor, and aluminum hydroxide powder is exposed after drying, which can cause a problem of wp1akas that reduces the adhesion when the molded article is attached to an iron plate.
