The present invention is an ankle pump device, comprising: a base plate seated on the ground; It consists of a holding member for inserting and holding the foot at a predetermined height from the ground, an alignment member for gathering the foot inserted into the holding member, and a standing member for standing the tip of the toe. A leg support that allows the lowered state to be maintained; It relates to an automatic ankle pump device comprising: an ankle pump member disposed on the base plate in front of the leg support and generating a pumping action by pushing up blood in the calf vein (vein).

In general, ankle pump exercise refers to the process of hitting the area close to the calf (hereinafter referred to as "ankle" for convenience) from the Achilles tendon while alternately lifting and dropping both legs in a lying or sitting position, thereby repeating the process of hitting the foot and It refers to an exercise that can improve the blood circulation of the body by forcibly transporting the blood that has deteriorated to the calf side toward the heart.

Figure 1a) is a photograph for explaining a conventional manual ankle pump exercise, Figure 2 is an exemplary view comparing the posture during the ankle pump exercise.

Conventionally, when performing an ankle pump exercise, a circular or semicircular ankle pump having a predetermined length and diameter is provided, and the circular or semicircular ankle pump is placed horizontally on the lower part of the ankle in a lying or sitting position. An ankle pump exercise was performed by alternately lifting and dropping the right foot and the left foot so that the right ankle and the left ankle alternately collide with the circular or semicircular ankle pump.

However, this conventional ankle pump exercise method is not helpful at all for the elderly who have difficulty lifting their legs, and the user lifts the legs using leg muscles and then drops them, resulting in a lot of fatigue. It also had problems with not being helpful or less effective for people suffering from varicose veins, where the venous valves were damaged. In addition, noise caused by hitting during exercise could cause inter-floor noise, so it was inevitable to shrink psychologically during exercise.

On the other hand, a desirable ankle pump exercise posture is to pull the tip of the toe tightly when lifting the leg so that the bent veins (extruded veins) of the ankle are stretched, and when dropping the leg, release the force and drop so that the soleus muscle contracts and stretches to improve blood circulation. can lead to promotion of The reason for this is that the soleus muscle wraps around the vein as shown in FIG. 3b). When the force is released, the vein swells and opens up so that the blood rising from the foot side can come up. This is because the venous valves close and the upper valves open, returning blood to the heart.

However, the ankle pump devices disclosed in the prior art, including the ankle pump health device of FIGS. 1b) and 1c), simply provide a function of automatically lifting and dropping the user's leg, so that the bent veins of the ankle are straightened.

Hereinafter, the automatic ankle pump device according to the present invention will be described in more detail with reference to the accompanying drawings.

In the present invention, the ankle pump exercise is an exercise that can facilitate the blood circulation of the body by stimulating the lower calf just above the ankle to forcibly transfer the blood whose flow in the foot and calf side has deteriorated. Refers to movement to help flow.

3a) and 3b) show the principle of blood circulation and the structure of the lower extremities for understanding the ankle pump movement. The venous valve under the soleus muscle is closed while the vein is pressed when force is applied, and the upper valve is opened to allow blood to return to the heart. However, this help also occurs only when the soleus muscles are moved, so people in occupations where they sit still or maintain a standing posture for a long time without moving their legs do not receive help from the soleus muscles, so blood pools in their legs, and if this phenomenon is repeated, This causes the venous valves to stretch, resulting in varicose veins, which leak blood into the feet.

In addition, as shown in FIG. 2, if the foot is spread outward during the ankle pump exercise, the pump device stimulates the calf bone (fibula) side, not the vein, so it is not helpful at all, and even when the tip of the toe is lying down, the vein can be effectively stimulated. Therefore, the effect of exercise is bound to be reduced.

In the ankle pump device for the above-described ankle pump exercise, the present invention automatically gathers the feet in a state in which the leg is lifted, and then raises the toe to perform the pump exercise through an ankle pump member to be described later in a state in which the bent veins of the ankle are stretched. Disclosed is an automatic ankle pump device, which is characterized in that it can provide excellent exercise effects by being made.

4 and 5 are schematic diagrams showing an automatic ankle pump device according to the present invention. As shown in FIGS. 4 and 5, the present invention includes a base plate 100, a leg support 200 disposed behind the upper surface of the base plate, and an ankle pump member 300 disposed in front of the leg support on the upper surface of the base plate. ).

6 to 9 are schematic diagrams showing a leg support according to an embodiment of the present invention, wherein the leg support 200 includes a mounting member 210, an alignment member 220, and a standing member 230. do.

First, the mounting member 210 is inserted and placed at a predetermined height from the ground so that the leg is maintained in a lifted state, and extends vertically from the bottom plate 211 on which the heel is seated and the rear edge of the bottom plate The formed vertical plate 212 is integrally formed, and when viewed from the side, approximately "

“It is made in the shape of a ruler.

The bottom plate 211 is combined with a vertical panel 202 of a predetermined length installed vertically on the base plate 100 seated on the ground and placed at a predetermined height from the ground, so that the feet are placed at a predetermined height from the ground. .

The bottom plate 211 is preferably formed with a predetermined width so that the heel portion can be stably seated while sufficiently contacting it, and preferably has a sufficient length to support both feet at a predetermined interval.

The vertical plate 212 extends vertically from one edge of the sole plate 211, and when the user places his/her foot on the sole plate, it closely adheres to the sole of the foot so that the tip of the toe is naturally erected.

In the case of the pump device of FIGS. 1b) and 1c), it only provides a function of automatically lifting and dropping the leg, so it is possible to exercise with the toes lying down while the feet are spread outward according to the user's age or health condition. There may be a problem in which the effect is remarkably low, and there is an uncomfortable problem in which an effort to put the feet together and then to stand up is required to maintain a correct posture.

The holding member 210 according to the present invention is in the form of forcibly erecting the foot by a vertical plate when the user lifts the leg and puts the foot, and can prevent the tip of the toe from lying down.

Next, the alignment member 220 is a member that aligns both feet so that both feet are erected by gathering the feet inserted into the mounting member toward the center.

Referring to FIG. 6, a drive motor 221 for alignment rotated in a forward or reverse direction by power and a gear box 222 to which power of the drive motor for alignment is transmitted are provided at the center of the rear surface of the vertical plate. A feed screw 223 for alignment is connected to the driven shaft of the gearbox along the horizontal direction.

An alignment plate 225 that adheres to the outer portion of the foot is formed on the front surface of the transfer plate.

Here, the alignment transfer screw 223 has threads formed on both sides of the gear box in different directions, so that when the alignment drive motor 221 is driven, the transfer plates 224 on both sides simultaneously move to one side (inner side). ) and get closer to each other or move to the other side (outside) and move away from each other. For example, when the foot is seated on the bottom plate, it can naturally spread outward. When the driving motor 221 for alignment is operated, the alignment plate 225 moves from the outside to the inside along the transfer plate 224 and moves to the outside. By gathering the widened feet inward, you can make them stand naturally.

In addition, as shown in FIG. 7, fixing brackets 226 to which the ends of the transfer screws for alignment are rotatably coupled protrude from both ends of the rear surface of the vertical plate 212, and the transfer screws for alignment 223 A pair of guide bars 227 disposed along the horizontal direction passing through the transfer plate are provided at the top and bottom, respectively, and shake when the transfer plate 224 and the alignment plate 225 move left and right by an alignment drive motor. can prevent

In addition, in the center of the bottom plate 211, an auxiliary alignment plate 213 protrudes upward from the bottom surface, dividing the space on the bottom plate vertically while being in close contact with the inner edges of the feet gathered in the center by the alignment plate, on both sides Keep your feet upright.

Next, the standing member 230 is a member that straightens the bent veins of the ankle by pushing the toe of the foot erected by the alignment member 220 forward and standing the toe.

6 and 8, at the rear of the vertical plate 212, a drive motor 231 for standing is disposed on the top of the gearbox, and a nut 2321 is fixed to the rear of the vertical plate 212, The lifting screw 232 screwed to the nut 2321 is connected to the rotating shaft of the lifting motor.

When the driving motor 231 for standing is driven in the forward or reverse direction, the driving motor for standing is moved back and forth along the transfer screw 232 fixed to the nut 2321 .

In addition, on both sides of the driving motor 231 for standing, a pressing member 233 that moves forward and backward together with the driving motor for standing is coupled.

The pressing hole 233 penetrates the vertical plate 212 and is disposed at the rear of the vertical plate. When the driving motor 231 for standing is driven, it protrudes forward along with the driving motor for standing and protrudes forward of the vertical plate to support the heel. As you push, keep your toes standing.

The pressurizing part 233 may be formed in an appropriate shape, for example, a cube or a rectangular parallelepiped so as to sufficiently contact the forefoot.

According to the present invention, a pump exercise is performed by the ankle pump member in a state in which the bent veins of the ankle are stretched while the tip of the toe is erected through the standing member 230, so that remarkably excellent exercise effects can be provided.

10 to 12 are schematic illustrations for explaining the ankle pump member 300, the ankle pump member 300 is disposed in front of the leg support on the base plate, and the calf side of the calf vein (vein) It is a member that pushes up the inner blood and causes a pump action.

10 to 12, a pair of ball nuts 3101 are fixed on the upper surface of the base plate at a predetermined height from the bottom surface, and both ends of a predetermined length rotatably coupled to the ball nuts 3101, respectively. A transfer screw 310 for the pump is provided.

In addition, the present invention is a transfer block 330 screwed with the pump transfer screw via a ball nut 3101, and a pump disposed on the top of the transfer block and closely attached to the ankle when the leg is placed on the support member A roller 340 is provided, and a pump drive motor 320 having a rotating shaft connected to the pump feed screw 310 is provided.

The pump roller 340 is linearly moved forward or backward along the pump transfer screw 310 together with the transfer block 330 by the pump drive motor 320, and is moved in a rolling motion while being in close contact with the ankle. It performs an automatic pumping movement that pushes up the blood in the veins of the side and causes a pumping action.

In addition, in the present invention, a pair of guide rods 311 connected to the transfer block are provided side by side on both sides of the transfer screw for the pump, so that when the drive motor 320 for the pump is driven, the transfer block 330 and the pump roller 340 ), it is possible to move stably in a straight line without shaking.

Although the pump device as shown in FIG. 1a) has a relatively simple structure, it has a high risk of injury, and it is not easy to control the uniform pressure and frequency, so the exercise effect is significantly reduced. In particular, exercise itself is bound to be a burden for patients and elderly people who are uncomfortable with activities alone.

In the present invention, anyone can easily and conveniently perform an automatic ankle pump exercise through the ankle pump member 300, and in particular, the elderly or patients with disabilities can perform the exercise by themselves or with minimal assistance. .

On the other hand, although not shown in the drawing, in the present invention, the pump transfer screw (310) and the pump drive motor 320 are components for reciprocating linear movement of the transfer block 330 and the pump roller 340, and are infinitely It may be replaced by a cylinder in which the rod is withdrawn/retracted along a straight line by reciprocating movement by a track, pneumatic or hydraulic pressure.

Next, a square or rectangular holder plate 331 is coupled to the upper surface of the transfer block according to the present invention, and a “┗┛” shaped holder 332 is coupled to the upper surface of the holder plate along the width direction, , A "┗┛" shaped pump roller support 333 having a wider width than the holder is coupled to the top of the holder.

In addition, a pivoting shaft 3331 hinged with the cradle is protruded from the lower surface of the pump roller support 333 so that the pump roller support can rotate back and forth from the cradle by a predetermined angle.

Here, the pivot shaft 3331 is formed eccentrically on the front side of the bottom of the pump roller support 333, and between the base plate and the pump roller support, a shock absorber supporting the bottom rear of the pump roller support , 350) is installed vertically.

The shock absorber is composed of a cylinder 351 and a piston 352 reciprocating in the cylinder. can increase

In addition, a buffer cap 353 made of any one of rubber, leather, artificial leather, soft PVC or silicone is coupled to the top of the piston 352, and the piston 352 and the pump roller support 333 ) can prevent friction or scratches caused by direct contact, and can prevent slipping by improving frictional force.

The pump roller 340 is rotatably coupled inside the pump roller support 333, and pushes the blood in the blood vessels (veins) of the calf side toward the heart while performing a rolling motion along the calf from the bottom of the calf. For example, when the transfer block 330 is moved from the rear of the base plate to the front, the pump roller moves from the lower part of the calf along the calf to perform a pumping motion that pushes up the vein.

At this time, when the transfer block is moved while the pump roller 340 is in close contact with the upper ankle, the pump roller support 333 is inclined backward. The pump roller support is elastically supported.

The present invention can keep the pump roller firmly attached to the ankle through such a variable elastic structure, and can move up and down according to the height of the calf by the buffering action of the shock absorber, thereby reducing the pressure in the veins (veins) of the calf. It can force blood to rise toward the heart.

On the other hand, reference numerals 201 and 301 in the drawings for understanding the present invention are cases for protecting motors, screws, shock absorbers, etc. constituting the leg support and the ankle pump member, respectively, and may be made of various shapes or materials.
