Description

Rolled crutches {Roly poly crutches}

The present invention relates to a crutch that assists walking movement, and more particularly, having a self-supporting function that can stand on its own, such as a crest, without requiring a special space for storage or a separate element that can be built. In addition, it is related to the crutches that can help the child to develop balance and gait training, which can induce interest and fun of children with motor development disorders, such as toys.

Crutches are assistive devices used by patients who are unable to walk normally because of abnormalities in their bodies, especially the lower body due to congenital disorders or acquired accidents.

1 is a view showing the most commonly used crutches (1). However, the two crutches are most often used in pairs, but since the left and right crutches have the same shape, it is sufficient to describe one crutch, which will be described with reference to FIG. Will only show and explain one crutch.

Referring to Figure 1, when explaining the structure of the general crutches 1, a pair of skeletal portions 14 extending downwards are installed at both ends of the shoulder support 10, which is inserted under the patient's armpit and supports the shoulder. The central tip portion of the visible skeletal portion 4 is connected to the handle portion 12 for operation while the patient is holding by hand and applying a force.

And between the ends of the skeletal portion 14 is gradually reduced to face the passing through the handle portion 12 is provided with a fixed support 16 for supporting the entire weight of the pedestrian (patient) in direct contact with the bottom surface, fixed At the distal end of the pedestal 16, a cushioning portion 18 made of rubber material for absorbing the impact of contact with the bottom surface is formed. Depending on the crutches 1, the length of the fixed base 16 protruding from the skeletal portion 14 may be adjusted.

Referring to the method used in the conventional crutches 1 having the structure as described above are as follows.

In order to use the crutches 1 to walk by the patient with his / her own strength, the patient who has an uncomfortable leg first grasps the handle part 12 by hand, inserts the armpit into the shoulder support part 10, and then ends (buffer part) of the fixing base 16. As you add weight to the walking floor, you lift your uncomfortable legs and move your body forward. According to this series of motions, the crutches 1 show a similar movement to the pendulum movement from the shoulder support 10.

However, the above-described series of operations using the conventional crutches 1 shown in FIG. 1 are quite significant even in adults because all weight is concentrated on the armpits held by the shoulder support 10 and the arms held by the handle 12. It's painful.

In addition, according to the pendulum movement of crutches (1), the contact area between the end (buffer) and the bottom surface of the fixed base 16 decreased and increased. If the surface is slippery or slightly distracted during walking, it is easy to fall, and thus there is a problem of high risk of secondary accidents.

Therefore, as an alternative to this, various crutches, such as an arched crutch having four feet, were introduced, and these crutches were mainly used by children or the elderly who lack overall strength.

Crutches have been used for a wide range of function-oriented purposes to assist the walking of patients with mobility problems, regardless of age or sex, but the crutches of FIG. 1 cannot stand on their own. Many, which are undesirable for hygiene.

In addition, even if the crutches are kept upright, they require a separate space to lean on or a separate element (for example, a trivet) to be inefficient in space usage. And the four-foot arched crutches, although they may stand on their own, have less space because they take up more space. In particular, hospitals and nursing homes with a large amount of crutches cannot easily ignore their space efficiency.

On the other hand, crutches are used for the purpose of balancing and gait training, which are necessary for children with motor development disorders such as cerebral palsy. In particular, children with motor developmental disabilities can reduce the level of disability and have a positive effect on intelligence development only when balance and walking training are performed at the appropriate time. The importance is incomparably high.

In other words, children are sensitive to the surrounding environment and develop according to the response, so stimulation of sight, hearing, and touch is very important. Therefore, play therapy for continuous stimulation of the sense is necessary to create gait. .

However, most children who need walking training tend to give up because they feel it is difficult to use crutches, and even after some treatment, walking motions that were difficult to learn were prevented when using wheelchairs. This may be degraded.

Therefore, it is very effective if the crutches have the elements that can be interesting and fun while the children with disabilities who are easy to balance and walk training are difficult and tedious.

However, it is difficult to expect that children's crutches, which are still reduced to adult crutches, are expected to induce the interest of trained children, and thus improvement is urgently needed.

The present invention has been devised to overcome the problems or limitations of the conventional crutches as described above, having a self-balancing function that can stand on its own balance such as a stand, a special space for storage or can be built separate Its purpose is to provide a crutch that can reduce the boredom of balance and gait training by inducing interest and fun of children with motor development disorders, such as a critter, a toy.

According to an embodiment of the present invention, the crutches have a shoulder support portion inserted under the armpit of the patient to support the shoulder, a skeleton portion extending downward from both ends of the shoulder support portion and connected at the end thereof, and the skeleton portion so that the patient is gripped. A body including a coupling portion formed of a handle portion formed to connect an intermediate portion to each other, and a space formed inside the distal end of the skeleton portion; It includes; and a fixed leg consisting of a connecting leg fitted into the coupling sphere, the lower tip of the arc (弧 shaped) provided on one end of the connecting leg.

The coupler is provided with a plurality of first binding holes arranged in a line in the vertical direction, and the connection leg is provided with a first tungsten protrusion elastically inserted into any one of the plurality of first binding holes.

In addition, the two opposite side skeletal portions are provided with a plurality of second binding holes arranged in a line in the vertical direction, respectively, and both ends of the handle portion are elastically connected to any one pair of second binding holes facing the plurality of second binding holes. Each of the second bump protrusions to be inserted may be provided.

In the embodiment of the present invention, the body is preferably made of a plastic material harmless to the human body.

And the body may be formed integrally.

In addition, in the embodiment of the present invention, when the handle portion is detachable, the body is made of a plastic material harmless to the human body, the shoulder support and the skeleton portion and the coupler may be integrally formed.

Meanwhile, in the embodiment of the present invention, the lower tip may include a center tip directly connected to the connecting leg, and a pair of wings extending from the center tip to both sides thereof.

Here, the wing portion may be extended by rotating in the vertical direction from the center tip.

In particular, when the wing portion is extended by rotating in the vertical direction from the center tip, it is preferable that the wing portion is geared to the inner side of the center tip is coupled to the other side according to any one rotation.

And the center tip may be formed in the shape of a human or animal foot.

In addition, the teeth of the wing is interlocked by the movement of the rack by interlocking the teeth interposed by the rack linearly moving in the vertical direction, the upper end of the rack is configured to be connected to the wire exposed to the outside extending to the handle portion May be

In this case, a cut ring is coupled to the end of the wire exposed to the outside, and a hook is provided at the bottom of the handle to fix the hook, and the length of the wire is completely fixed when the hook is fixed to the hook. Set to unfold.

In the embodiment of the present invention, the connecting leg may be made of a metal or reinforced plastic material including aluminum.

And the shoulder support and / or handle portion is preferably wrapped with a cushion material.

Meanwhile, in the embodiment of the present invention, the bottom of the lower tip is provided with a switch that responds to pressure at a point spaced from the center along the arc direction, and the body includes acoustic means and / or light emitting means electrically connected to the switch. Can be.

In the present invention, since the lower tip is provided in the fixed base positioned at the bottom of the crutches, it has a self-supporting function that can stand on its own, such as a toy tower, and has a special space for storage or a separate stand. There is no need for urea, so it is easy to store and handle and is hygienic. In particular, because the crutches are always standing, it is convenient to use even in the case of patients who are uncomfortable lifting the crutches lying on the floor.

In addition, since the present invention also has a function as a play equipment such as a toy puppet, it causes the interest and fun of a child with a developmental disability to recognize the balance and gait training as a boring experience such as play therapy. The advantage is that it can be greatly enhanced.

In particular, if a child with a developmental disability performs accurate gait movements, the sound or light can be notified to continue to stimulate the sense of achievement and interest, which may further improve the efficiency of daily life movement training.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the stepped crutches 100 according to the present invention.

In describing the embodiments of the present invention, a description of well-known structures that can be understood by those skilled in the art will be omitted so as not to obscure the gist of the present invention.

In addition, when referring to the drawings, it should be considered that the thickness of the lines or the size of the components shown in the drawings may be exaggerated for the sake of clarity and convenience of the description. Terminology, such as upper and outer (內外) is based on the viewpoint (視點) of the person using the crutches 100 unless otherwise specified.

2 and 3 is a view showing the overall appearance of the stepped crutches 100 according to an embodiment of the present invention. As shown in the figure, the stepped crutches 100 is composed of a fixed support 300 in direct contact with the body 200 and the walking floor surface to be held by the patient in close contact with the body.

Body 200 has a structure similar to the conventional crutches shown in Figure 1, the shoulder support 210 and the shoulder support 210, which is inserted under the patient's armpits and extends downward from both ends of the shoulder support 210 Skeletal portion 220 connected at the end and the handle portion 230 is formed to connect the middle portion of the skeleton portion 220 to each other so that the patient gripping, in particular a space formed in the end of the skeleton portion 220 inward To form a coupler (240).

And fixed base 300 is detachably configured to the body 200 is connected to the coupling leg 310 is fitted into the coupling port 240 of the body 200, and the arc shape provided at one end of the connecting leg (310) ( Consisting of the lower tip 320. The body 200 and the fixed pedestal 300 is shown in Figure 8 is combined.

The connecting leg 310 is a part connecting the body 200 and the fixed base 300, and because the load transmitted from the body 200 is concentrated, it is made of a metal or reinforced plastic material containing aluminum, It is good to have sufficient strength.

An important part of the configuration of the fixed pedestal 300 is a lower tip 320 formed in an arc shape, the lower tip 320 is to balance the crutches 100 do not fall like a pile when the crutches 100 are stored. It has a weight enough to move the center of gravity of the entire crutch 100 close to the ground so as to be able to stand on its own, and when using the crutch 100, it is also a part that contacts the ground to support the load of the patient.

Since the center of gravity of the crutches 100 must be sufficiently low in order for the crutches 100 to stand as balanced, the weight of the body 200 needs to be relatively lightweight compared to the lower tip 320. Therefore, the body 200 is preferably made of a light plastic material, in which case it is much easier to form the body 200 integrally. In particular, considering that the patient is a child with a developmental disability, it is preferable to be made of a plastic material that is harmless to the human body like a general toy.

This is because it is very easy to make the interior of the body 200 hollow while maintaining the appropriate strength if the body 200 is made of plastic material, it is very advantageous to the weight of the body 200, and such plastic material is conventional wood or aluminum Unlike metal materials such as the like, the surface can be varied, which can stimulate children's touch.

In consideration of the height and body shape of the patient, the coupling hole 240 of the body 200 forms a plurality of first binding holes 242 in a line in the vertical direction, and the connecting leg 310 of the fixed pedestal 300. ) May be configured such that the first tungsten protrusion 312 is elastically inserted into any one of the first binding hole 242. That is, by adjusting the insertion position of the fixed base 300 by adjusting the position where the first tungsten bump 312 elastically retreats according to the action of the external force is fitted to the first binding hole 242, the crutches 100 The height of the whole can be adjusted. In addition, it is also possible to use a variety of types of lower support 320, in particular, various types of fixed support 300 to vary the weight and shape.

In addition, a plurality of second binding holes 222 are formed on both sides of the body 200 facing each other in the vertical direction in a line, and the second binding holes 222 are formed at both ends of the handle part 230. 222, if each provided with the second second projections 232 elastically inserted into the pair of second binding holes 222, it is possible to adjust the position of the handle portion 230, the height of each patient and Can be used as a custom crutch more suitable for body shape. And in the present embodiment capable of detachable handle 230, the shoulder support portion 210 and the skeleton portion 220 and the coupler 240 of the body 200 is integrally formed. Of course, even in this embodiment, the body 200 may be made of a plastic material harmless to the human body.

In addition, the cushion support 250 is wrapped in the shoulder support 210 and / or the handle 230, which is a portion of the crutch 100, which is in direct contact with the patient, even when the crutch 100 is used for a long time. It is desirable to reduce fatigue through load distribution and cushioning. In addition, the cushioning material 250 also serves to protect the skin of the patient in contact.

Meanwhile, in the embodiment of the present invention, the lower tip 320 may be integrally formed with an arc-shaped lower tip 320 as shown in FIG. 7, and the connecting leg 310 as shown in FIGS. 4 to 6. It may be composed of a central tip 322 directly connected to, and a pair of wings 324 extending from both sides of the central tip 322.

In particular, the wing portion 324 shown in Figures 4 to 6 has a structure extending from the center tip 322 to rotate in the vertical direction, although not shown in the telescopic manner along the front and rear direction from the center tip 322 It is also possible to withdraw and expand.

When the lower tip 320 is able to vary the area in contact with the bottom surface, there are various convenient points. That is, when the contact area of the lower tip 320 is extended to the maximum, the stud can be stored upright on the crutches 100, and the patient has a weak sense of equilibrium, such as an unfamiliar patient or a child with developmental disabilities or muscle strength, just starting walking training. It is possible to considerably reduce the fall of a patient who lacks a lot. And when the walking training is mastered by reducing the contact area of the lower tip 320 by folding the wing portion 324 can be moved to the next step of training.

As shown, when the wing portion 324 rotates upward and downward from the center tip 322, the wing portion 324 is connected to the gear 326 inside the center tip 322, the other side according to the rotation of one side This can also be configured to expand together. This is convenient because the expansion of the wing portion 324 is completed in one operation, and the spreading degree of both wing portions 324 may be different to prevent a phenomenon in which an imbalance occurs during walking.

Also, like the lower tip 320 illustrated in FIG. 6, the center tip 322 may be formed in the shape of a human or animal foot to further increase the contact area, and at the same time, increase the curiosity and intimacy of the child patient.

The integrated lower tip 320 shown in Figure 7 can be said to be a fairly heavy weight, which is useful for muscle strength exercise between the trunk using the crutches 100 of the present invention. This is distinguished from the use case of the lower tip 320 is provided with a wing portion 324 mainly used for walking.

In most cases, physical therapy in the hospital is only about 30 minutes, so personal exercise at home is very important. Therefore, the use of the fixed base 300 is provided with a heavy one-piece lower tip 320 has the advantage that the disabled child can effectively perform the interbody strength exercise with the mother at home or indoors.

FIG. 8 shows an example in which the wing portion 324 illustrated in FIGS. 4 to 6 is rotated in the vertical direction from the center tip 322 to expand.

In the modification of FIG. 8, the gear 326 is provided at the wing 324 so that both wings interlock with each other, but there is a difference in that the rack 330 for driving the gear 326 is interposed.

That is, like the rack and pinion mechanism, the wing portions 324 of both sides engaged with the rack 330 through the gear 326 in accordance with the vertical movement of the rack 330 is rotated in the vertical direction.

In addition, a rigid wire 332 is connected to the upper end of the rack 330, and the wire 332 extends toward the handle 230 through the inside of the connecting leg 310 and is exposed to the outside. Accordingly, when the wire 332 is pulled up, the rack 330 rises upward to spread the wing portions 324 on both sides. On the contrary, when the wire 332 is pushed down, the wing portions 324 on both sides rotate upward to be folded. do.

The rack 330 and the wire 332 are included because the user can easily unfold or fold the wing 324 without bending the waist or lifting the crutches 100. In particular, it can be said to be very useful for patients with discomfort or the elderly.

In addition, the connecting rod 310 extends through the inside of the handle portion 230 and coupled to the cut ring 334 to the end of the wire 332 exposed to the outside, a thin rod extending laterally under the handle portion 230 It is also preferable to provide the hook 334 of a shape.

When the length of the wire 332 is set so that the wing 324 is fully extended when the hook 334 is fixed to the hook 334, the hook 334 is hooked when the crutch 100 is mounted upright. ) And spread the wing 324, and when walking using the crutches 100, it is more convenient to use simply by removing the hook 334 from the hook 334.

On the other hand, as shown in Figure 9, the embodiment of the present invention has a switch 328 in response to the pressure on the bottom surface 323 of the lower tip 320, the body 200 is electrically connected to the switch 328 And sound means 260 and / or light emitting means (not shown) connected to each other.

When walking with the crutches 100, the switch 328 provided on the lower tip 320 is in contact with the bottom surface. Therefore, the switch 328 is activated only when the correct walking operation using the crutch 100 is made while applying force. However, it should be noted that the switch 328 illustrated in FIG. 9 is somewhat exaggerated to help understanding, and the switch 328 protrudes only to the extent that it does not interfere with the self-supporting function of the crutch 100.

This means that if a child with a motor development impairment performs the correct walking motion, the sound (for example, well done, applause, animal sound, etc.) or light can be notified to continue to stimulate the sense of accomplishment and interest. It helps to improve the efficiency even more.

Although the present invention has been described with reference to the embodiments shown in the drawings, it is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the claims.
