Description

Knee Protector for Mountaineering{KNEE PROTECTOR FOR CLIMBING}

The present invention relates to a knee protector for mountaineering, and more particularly, has a structure in which a spring combination is coupled between the thigh side belt and the lower leg side belt, and can be worn from the start of mountain climbing, and supports the motion of bending the knee when climbing. It has the effect of reducing consumption and relates to a knee protector for mountaineering that can protect the knee from damage by supporting the knee when descending from the mountain.

There is an increasing number of mountaineering enthusiasts who wear knee braces when mountaineering. Currently, general knee braces on the market are made up of compression, which restrains the activity of the knee by tightening the belt and restricts excessive movement of the knee. The guard has a number of disadvantages when climbing.

Since the above compression type knee protector must be tightly tightened so that the knee is not bent in order to exert its function, it cannot be worn when climbing a mountain and is mainly used only at the last descending.

In addition, the above knee protector slips down continuously during mountaineering, and it is often troublesome to fix it, and it is difficult to fix it when worn inside pants in consideration of its appearance.

In addition, since the knee protector should be used in a state where the band is tightly tightened, there are frequent cases of numbness in the leg due to obstruction of blood circulation in the leg.

In addition, since the knee protector is effective only when the knee is tightened strongly, the impact applied to the joint is greater than the case of landing with the knee bent because it lands on the ground with the leg extended.

Patents proposed as knee protectors related to the prior art include No. 10-0970759 Joint Protector and No. 20-0474247 Joint Protector.

In order to solve the above-described shortcomings of the compression type knee protector, the present inventor has obtained a patent registration as a climbing knee protector (No. 10-1551082) having a structure in which a spring assembly is connected between the thigh belt and the lower thigh belt.

1 to 3 is a conventional climbing knee protector developed by the present inventor, the femoral side belt 110 and the lower leg belt 120, a spring assembly connecting the femoral side belt and the lower leg belt ( 100) is included, and the spring assembly includes a femoral spring case 150 having a spring guide part 151, a spring fixing part 152, and a spring fixing groove 153 formed therein, and a spring take-up hole The lower leg side spring case 160, the spiral spring 170, the femoral side connection plate 130, the lower leg side connection plate 120, the pin 180 and the plug 190 as a coupling member with 161 formed therein. ) And a bolt 200.

When the leg is unfolded, the refraction angle of the leg is from 130 degrees to 160 degrees, and the spiral spring assembled inside is wound, and at the same time, the elastic force acts to suppress the motion of stretching the knee, and induces the leg not to be fully extended when landing. When doing so, it acts so that the leg facing forward is easily bent due to the restoring force of the wound elastic body.

In addition, as a male Velcro tape 220 bonded to the outer surface of the femoral side connection plate 130 and the lower leg side connection plate 120, it is sewn for a certain section on the left and right sides along the inner circumferential surface of the thigh belt and the lower thigh belt. Since the arm can be attached to and detached from a coupling member such as Velcro tape 230, it is configured to adjust the position of the spring assembly according to the individual body shape.

The knee protector according to the prior art of the present inventor described above has the advantage of reducing fatigue when walking for a long time due to less aching of the knee after climbing compared to the compression type knee protector, and a walking aid function by the restoring force of the spring.

In addition, even if the belt is smoothly fastened, it does not continue to flow down, and the number of times of fixing it by maintaining the position after flowing down slightly is reduced, and there is an advantage that the feeling of pressure and discomfort are remarkably low because the belt does not need to be tightened strongly.

However, the conventional knee protector described above has a problem in that noise is generated by generating a frictional sound between metals in the process of winding and restoring a spring that has been used.

In addition, the used helical spring has a problem that the thickness of the spring case including the spring becomes thick because the width of the spring steel wire must be wide in order to maintain an appropriate elastic force.

In addition, the spiral spring used as an elastic body, which is an important part, has a problem that the purchase unit cost is higher than that of other springs, so that the product cost increases, and as the number of uses increases, the initial elastic strength decreases quickly, resulting in a short product life. have.

In addition, when the belt is gently worn in the knee protector, the belt on the lower leg is fixed and there is no separation, but there is a problem that the belt on the thigh side slightly descends from the initial wearing position.

In addition, the connection plate connecting the spring assembly and the belt has a problem in that air does not pass through because a through hole is not formed.

Also, if you look at the structure of the knee from above in an upright state, it is narrow toward the patella and wide toward the popliteal part. When standing while wearing a knee protector, a gap between the knee patella and the spring assembly is widened, and when walking on a forest path, there is a problem that the walking becomes obstructed by being caught by an obstacle.

In addition, there is a problem that the inner surfaces of the upper and lower belts do not evenly adhere to the surface of the legs.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 4 to 11, focusing on features.

The knee protector for mountaineering according to the present invention is a carrier 320, a straight compression spring 310, an upper plunger 330 and a lower plunger 331, the thigh side connection plate 340 and the lower leg connection as shown in FIG. 5 It is composed of a spring assembly 300 consisting of a plate 341, a cover 350, a bolt 360, and a pin 365, a thigh side belt 370 and a lower leg side belt 380, and the user climbs When the leg is bent and stretched, the straight compression spring 310 assembled inside the spring assembly expands and contracts in the longitudinal direction along the curved portion 321 inside the carrier 320 forming a gentle curve It has a structure that supports the knee when unfolding and supports the gait motion when the leg is bent.

Examples of springs that can be used in the knee protector according to the present invention are similar to the spiral spring used in the prior art of the present inventors, as well as torsion (torsion) springs, straight compression springs, and straight compression springs, but in an arc shape rather than a straight line. It is possible to present a coil spring to be manufactured, that is, a curved spring.

The spring shown in FIG. 6 is a view when the straight compression spring is assembled to the carrier, but the spring shape shown in the drawing is the same as the curved spring shape.

The curved spring is most suitable in terms of performance, friction noise, and durability, but has a disadvantage in that the number of orders per order must be large if the manufacturing process is not easy and there is no own production facility.

Therefore, while utilizing the advantages of the curved spring in terms of performance, a linear compression spring is used that is considerably low in terms of cost, and a suitable body, that is, a carrier 320 of an optimal structure, is designed to effectively exhibit the performance of the spring. The main point of the present invention is to implement the optimal function.

As shown in Figure 6, the carrier 320 is provided with a curved portion 321 in the body portion, the curved portion 321 is a section in which the expansion and contraction movement of the spring proceeds, as a large arc as close to a straight line as possible, the expansion movement It is formed to have a structure that can minimize lateral deformation when performing.

In addition, a fixed guide portion 322 is formed on the body of the carrier 320 to support the central portion of the spring 310 and serve as a guide to prevent abnormal bending inside.

In addition, the carrier 320 is provided with two rotation shafts 323, a plunger having a through hole in the center is assembled and rotates in conjunction with the knee bent and unfolded, the upper plunger 330 and the lower plunger 331 The pressure portion 332 formed at the arc end of the spring continuously plays a role of simultaneously applying or relaxing pressure to both ends of the spring.

When the leg is extended, the angle between the thigh and the calf is 110 degrees to 130 degrees, and the spring is elastic and the force is applied to the knee, and the spring tension gradually increases until the leg is fully extended, giving support to the knee. .

Here, when each of the pressure portions 332 formed on the two plungers simultaneously presses or relaxes both ends of the spring, it is possible to prevent an early drop in elastic force than a method of fixing one end of the spring and applying pressure to the other end, The method in which both ends are pressed or relaxed at the same time has a characteristic that gives a soft feeling of use compared to the products of the prior art.

In addition, the spring assembly 100 according to the present inventor's prior art has a lot of gaps between the surface of the leg and the spring assembly in the vicinity of the patella, and there is a case of being caught in an obstacle and obstructing the walking. This is a bad problem.

The reason for the gap between the leg and spring assembly 100 is that the circumference of the thigh and the calf are thicker than the circumference of the leg joint, respectively, and when the structure of the knee is viewed from above, the joint portion has a shape close to a triangle and rotates from the front side to the side. With a wider structure, when standing while wearing a knee protector, the front-facing part of the spring assembly is quite open to the knee surface.

In order to solve such a problem, in the present invention, the shape of the connecting plate, which is a component of the spring assembly 300, is changed so that the front portion of the spring assembly 300 can reduce the gap with the patella.

In more detail, as shown in the bottom view of the connection plate shown in FIG. 9, the shape of the assembly groove 343 in the femoral side connection plate 340 and the lower side connection plate 341 with respect to the flat plate 342 When manufactured by twisting each of the upper and lower sides at an angle of 5 to 15 degrees, the spring assembly is naturally twisted as much as the twisted angle of the connecting plate so that the front can approach the knee.

In this case, the femoral side connection plate 340 and the lower leg side connection plate 341 have a symmetrical structure.

Next, the upper and lower belts, which are wrapped around the knee and fastened to the upper and lower belts, are made of polyester fabric on the inner side and fabric finished with arm Velcro brushed on the outer side, and the spring assembly 300 A male Velcro member is attached or sewn on the outer surface of the connecting plate, which is a component, and attached to the arm Velcro brushing attached by sewing on the inside of the belt, attached to the detachable state, or by sewing a pocket on the inside of the belt. It can be used by sewing it again after inserting the connecting plate.

In the prior art of the present inventor, when the belt is not smoothly circulated for a long period of time, the clothes around the knee protector are wetted due to the discharged sweat, and in the present invention, it is shown in FIG. As a bar, a number of through holes are formed in the connection plate () to accelerate moisture drying due to sweat, and as a component of the belt, members such as belt fabric, male Velcro, female Velcro, etc. are adopted as materials that allow air permeation. It is characterized in that moisture dries quickly to prevent skin abnormalities caused by moisture.

Next, there is a problem in that the upper and lower belts are not evenly adhered to the leg surface when the upper and lower belts are fastened in the prior art of the present inventors.

The reason for this poor close contact is that the thickness of the thigh and calf leg becomes thinner or thicker as it goes down.If the upper and lower belts are tied to the leg in parallel, the upper and lower part of the thigh direction in the thigh belt It becomes close and the bottom is not tight, and the upper side of the belt on the lower leg does not stick properly.

In the present invention, in order to prevent the inner side of the belt from being partially contacted as described above, one end of the thigh side belt is bent downward at an angle of 5 to 15 degrees, and the lower side belt is at the same angle upward. By pulling the bent part to fasten the belt to the knee and pulling the other end of the belt, the side that does not adhere in parallel is pulled more so that the upper and lower belts are evenly adhered to the knee surface.

Next, there is a problem that the knee protector worn when climbing with the protector is frequently flowing down. In particular, when climbing, you will continue to repeat uphill and downhill roads other than flat land, but if it is fixed frequently, you will avoid wearing a protector due to inconvenience.

The knee protector according to the prior art of the present inventor has relatively less belt flow compared to other products.

This is because the leg on the calf side gets thicker as the leg goes down from the knee joint, so the belt on the lower leg is not pushed down, and on the femur side, the thickness of the leg becomes thinner as it goes down from the thigh to the knee joint. Is mainly generated in the femoral belt, and when the leg is bent, the femoral belt is moved down, and when the leg is stretched, the folded spring assembly 300 is unfolded, and the femoral belt is pushed up to its original position.

However, at the beginning after wearing the protector, the belt on the thigh side slips a little and keeps it as it is, but there is a drawback that it flows a little.

The first cause of the belt flowing down in the knee protector according to the present inventor's prior art is that when the leg is bent because the spacing between the thigh belt and the lower belt is not adequate, the thigh belt is pulled down and the knee is sufficiently pushed up when the knee is stretched. The second reason is that slipping occurs between the clothes and the lining fabric of the belt.

In order to improve this disadvantage, as shown in FIG. 10, an anti-slip band is attached to prevent slip between fabrics, and the carrier 320 is made longer in a more rectangular shape, or the length of the plunger is made longer, so that the femoral belt and the It is possible to suppress the vertical movement of the belt by widening the gap between the lower leg side belts than the knee protector according to the prior art.

That is, by adopting a non-slip band and changing the structure to properly maintain the gap between the upper and lower belts, once worn, it can be used without fixing until the end of wearing.

In the above, a preferred embodiment of the present invention has been exemplarily described, and the scope of the present invention is not limited to the specific embodiment described above. Those of ordinary skill in the art will understand that various changes and modifications can be made without departing from the scope of the technical idea of the present invention.
