Description

The present invention relates to a mounting aid unit for elastic socks mainly used for medical purposes and a retainer thereof .

  Mainly, elastic socks for medical use have a function of applying an appropriate pressure from the ankle to the calf for the purpose of promoting blood flow in the veins of the legs. There are various types, high socks up to the knees, stockings up to the thigh, pantyhose and tights up to the waist, and the elastic pressure (between the strongest ankle to calf) is low pressure type (17mmHg = 22.6hPa) There are pressure type (30 mmHg = 39.9 hPa) and high pressure type (45 mmHg = 59.8 hPa), and the selection is generally determined by the diagnosis of the doctor in charge of the medical institution. There are also toes with or without toes and cylindrical ones, and they are also produced and sold in a wide variety, including those with thinner fibers and those with thicker ones. Therefore, the socks that are the subject of the present invention include not only feet and legs but also supporters used for hands and arms.

The general way to wear elastic socks is to insert the toes through the same mouth as normal socks, put your hands through the mouth, pick out the heel part, turn the mouth over, and remove the toes from the protruding heel. In the case of a sock without a toe, there is a method in which a slippery cloth bag is put on a foot in advance and the socks are pulled out from the opening part of the toe part. In addition, some socks manufacturers have socks that are made of rubber by interweaving rubber to improve stretchability, and slippery with glossy fibers with extremely low friction coefficient. It is still a difficult task for an elderly person or a woman with weak finger strength to push the fingertip to insert the toe from the ankle portion that has shrunk. Furthermore, since it is forcibly pulled up after putting the toe, there is a risk that the fiber will be damaged greatly and its durability will be shortened.

Although it seems that a few auxiliary tools have been developed to solve these problems, few have been put into practical use so far.

Unlike conventional socks, medical elastic socks have extremely strong elasticity (tightening), and when they are worn, it is necessary to put a considerable burden and time on the fingers, and for users every day This can be a painful and difficult task. There are many cases in which the purchase is stopped in a short period of time due to the pain and annoyance of the purchase. The socks are relatively expensive because insurance is not applied (except for lymphedema), and the elastic effect usually diminishes in 2 to 3 months, and the cost is also a major issue. However, practical use of excellent wearing aids that solve these problems has not been made.

In order to insert the foot into socks, the wearing aid unit in the present invention needs to be expanded to a foot width that matches the size of the user's foot. An expansion / contraction device is provided that operates the transmission operating lever that moves simultaneously.

In the present invention, as shown in FIGS. 12 to 15, the cages 1 a and 1 b do not have only a rigid force but are calculated based on the inherent longitudinal elastic modulus of the material used. of to generate bending to adapt to the repulsive force due to the elongation, and has a flexible property which does not give a load of more than necessary to the fibers in extending the hosiery. Provided is a wearing aid unit that has both convenience and comfort and does not damage the durability of socks, and has an anti-extension function.

  According to the present invention, for the user of the elastic socks, the wearing time generally takes 3 to 5 minutes for one foot and 5 to 10 minutes for both feet, and 1.5 to 2 minutes for the former and 3 for the latter. It was completed in ~ 5 minutes, and it became possible to fit more beautifully while being freed from time and pain.

As shown in FIGS. 1 and 2, the mounting aid unit is opposite to the left and right cages 1a and 1b at the same time.
A casing 7 that accommodates an expansion / contraction device that moves in a direction and a base 8 that includes a footrest 8a portion are fastened and integrated with screws or the like.

In addition, a handle 9 for lifting the entire unit is attached, and it is used for carrying and when in use, it is moved down to the position 9a shown in FIG. Sometimes used as a puller.

7 and 8 is installed on the upper surface 17a of the upper lid 17 of the casing 7, and is held in accordance with the name of the lock lever shown in FIG. 7, its control position, and the user's foot width. A scale and characters for expanding the vessel are displayed, and an indicator 21 for indicating the scale is attached to the column on which the cage is installed. The following is a detailed description of the main devices.

As shown in FIGS. 1 and 2 , the cage is arranged in the casing 7 symmetrically in order to insert and hold elastic socks according to the insertion position of the foot, and protrudes in parallel above the step 8a. By operating the left and right control levers 2a, 2b arranged on the operation side, the sock can be quickly expanded at the same time on the left and right, and the foot can be easily inserted .

Further, as shown in FIG. 5, for example, the main bone 1f is made of stainless steel, and the periphery is covered with 1 g of a plastic that is slippery. Therefore, while preventing the user's skin and socks from damaging the fiber, it is structured to absorb and relieve the load applied to the fiber by generating an appropriate deflection according to the resilience of the socks when expanding. .

Further, in order to reduce the transportation cost, the retainer has a structure that can be attached to and detached from a support column 10c that supports the retainer.

As shown in FIG. 4, the shape of the single cage is a horizontally thin spatula corresponding to the length of the foot, and has a symmetrical shape for use in a pair of left and right sides. It is curved. The side surface has a shape resembling a foot shape, in order to eliminate unnecessary expansion as much as possible.

As a structure, the base 1c is installed in a detachable fitting groove 1e, a long hole 1d that can be adjusted in the length direction of the foot, and a column 10c that can be adjusted in the height direction of the foot, and along the key groove 10d. It has a tightening screw 11a that can be fastened to a screw hole provided in the sliding key 11 that moves up and down to fix the cage simultaneously in both directions.

The base 1c of the cage has a sufficient rigidity, and at the same time, the insertion portion of the socks is a flexible structure that generates an appropriate deflection according to the direction of repulsion due to the elasticity of the socks.

The expansion / contraction device requires a synchronization mechanism for moving the retainer at the same time in order to set the elastic socks on the retainers 1a and 1b and to expand left and right. If the left and right operation levers 2a and 2b are moved independently, the operation lever of the stronger hand (for example, the right hand) moves first even when the levers are operated simultaneously. In other words, it moves to the side with less resistance, and one of them moves with a delay, and the center position between the retainers of the socks is displaced and the fibers are displaced. If the left and right are synchronized, this problem can be solved, and the expansion can be performed while maintaining the preset state so that the center between the toes and the heel is always in a straight line at the center position between the cages.

Structurally, as shown in FIG. 9, two links 19 and 20 that connect a pair of operation levers 2a and 2b arranged symmetrically are rotated by a swing lever 18 arranged at the center of the synchronization mechanism , It has a left-right movement synchronization function that can simultaneously move two sets of struts with left and right cages attached in opposite directions. It should be noted that this function can be performed not only by hand but also by foot because the operation lever moves simultaneously from the right and from the left. This is an effective function for users with disabilities in limbs.

As shown in FIG. 11, the operation lever 2 adopts the principle of lever, and the sock can be expanded with a small force. In addition, the left and right sliders 10 shown in FIGS. 10 and 11 are each supported by two linear ball bearings 12 and are fitted to the guide shaft 13. Due to their low rolling friction coefficient, the slider 10 can withstand a large load during expansion. Since it is possible to move lightly, there is an advantage that the ratio between the force point and the action point of the operating lever can be shortened, and the auxiliary tool unit can be downsized.

In addition, when the socks are set on the column to which the cage is attached and expanded by the operation lever, the difference between the moving center position D of the slider and the load position E of the cage is greatly deviated as shown in FIG. The repulsive force of the socks is absorbed by the deflection of the retainer and the support column 10c, and is not transmitted directly to the movement center position, so that the retainer is not returned in the contracting direction. Therefore, there is no need for additional devices such as stoppers, and the expansion / contraction device also has a function that can stop at any position without steps .

  “Foot” in the text means from toes to heels, and clearly distinguishes from “legs” from ankles to knees.

  When attaching elastic socks to the foot, the most difficult neck is the work of fitting the heel portion of the socks into the heel. As long as it is attached to the heel or ankle, it becomes a part with a relatively small elastic pressure and a large caliber, so it can be easily attached by tapping it along the shin or thigh.

Therefore, in the present invention, the elastic socks are expanded in the left-right direction, and the portion of the foot is expanded downward in order to securely fit the heel of the foot into the heel portion of the sock , and is not returned to the toe side. A hanging device is installed.

As shown in FIG. 8, the device 4 is located in the middle of the support column 10c supporting the left and right cages as shown in FIG. 1, and is installed on the upper surface 17a of the upper lid of the casing, and the rear end is connected by the upper lid 17 and the hinge 4a. The tip has a hook 4b for hooking into the indented portion of the bag, and can be freely moved between F , G and H.

  F is a position where the heel portion is expanded downward and fixed by the lock lever 5. G is
Normally, the spring 6 is flipped upward to the position of the socks. H is the maximum position where the hook is removed from the heel in order to remove the foot from the cage after the heel portion is worn.

  As shown in FIG. 7, the lock lever is rotatably installed on the upper lid 17a of the casing. The lock lever is fixed by moving the knob 5a in the “LOCK” direction and is released in the “FREE” direction. The hooking device has a space structure 4d for inserting the lock lever into the lock position and maintaining the fixation, and a lifting portion 4c for removing the lock lever from the bag.

The inventor of the present invention is a person suffering from varicose veins of the lower limbs and experiencing inconvenience when wearing elastic socks, so although it is a handmade prototype , the unit has been used for half a year. As a result of repeating the wearing of elastic socks every day and continuing the comparison with hand-wearing, and investigating the degree of influence on the fiber, it was proved that there was no damage to the fiber and it was more durable than hand-wearing. Of course, several types of socks described in the above-mentioned 0005, and socks manufacturers of some socks manufacturers have been tried on, and it has become a presence that cannot be released now in terms of convenience, comfort and accuracy.

Currently, the medical community says that there are 1 million people suffering from varicose veins and lymphedema in the country annually, and there are more than 10 million reserve groups. Since it can be estimated that it will reach the scale of several hundred million people from a global perspective, it is no doubt that the present invention will greatly contribute to the medical community, industry, etc. if it is recognized and gained public recognition. As described above, if the number of patients who stop using them in the middle due to inconvenience is reduced, it is good for patients and also profits for sock makers. In recent years, products such as elastic socks have been sold and used in the fields of beauty and sports, and needs in this field are also expected. If you apply it to ordinary socks with a wider width, even if your limbs are paralyzed, such as cerebral infarction, the socks are inelastic if one of your hands or feet is healthy. In the invention, since it can be easily set on the cage and the operation lever is synchronized with the left and right, it can be easily operated with only one hand and one foot, so there is a very high possibility of being used in the care field.
