Description

Lower step knee-pad shoe stretcher

Technical Field

The utility model belongs to the technical field of domestic equipment, a auxiliary device of shoes is related to, concretely relates to lower step knee-pad shoe stretcher.

Background

The inventor speaks a Hangul when climbing south mountain together with family: it is easy to go up the mountain and difficult to descend the mountain. However, from a general analysis, it is harder to climb up a mountain and make a hurry than to descend a mountain, and the proverb is harder to say down a mountain? Why is this?

Through analysis, when the user descends, the muscle of the leg of the supporting leg needs to bear the weight of the whole body and move downwards, and the movement distance exceeds that of the upper step. In particular, the muscles of the lower leg are far less developed than those of the upper leg. Therefore, the calf is more prone to soreness after climbing mountains. Meanwhile, when the user steps down, the user steps off the foot and then moves down to the next step, the impact caused by sudden stop after the user moves down can be borne by the knee joint, and the impact force of the user often exceeds the body weight. On the other hand, the upper step needs to lift the body, but the movement distance of the muscle supporting body is not longer than that of the lower step, and the knee joint does not bear large impact. Therefore, the adage of "easy going up and difficult going down" is pragmatic.

Starting from the proverb of the sentence, the inventor generates an idea of designing a labor-saving knee-pad shoe stretcher for descending steps by analyzing the main stress condition of the body when descending steps and combining basic physics knowledge.

The analysis on physics shows that when a user goes down a step, the human body moves from high to low and has certain potential energy. Without external devices, this potential energy needs the human body to offset, and the direct manifestations are leg muscle force and knee joint impact. The potential energy can just provide energy sources for the shoe stretcher, and no additional energy is needed, so that the shoe stretcher has physical feasibility.

Detailed Description

The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.

The utility model relates to a lower step knee-pad shoe stretcher wears on both feet, and when going downstairs, the elastic component of the shoe stretcher of the leg of stepping away stretches out, supports on next step, reduces the bearing of supporting leg, reaches laborsaving purpose. When the weight center of the body shifts to the step-off leg, the elastic component of the shoe stretcher is slowly compressed, so that the impact force to the knee joint is reduced, and the aim of protecting the knee joint is fulfilled.

Fig. 1 is a schematic view showing the lower step knee brace of the present invention when the elastic member is in an extended state. Fig. 2 shows a schematic view of the lower step knee brace of the present invention when the elastic member is in a compressed state. As shown in fig. 1 and 2, the lower step knee brace of the present invention comprises a fixing device 1 and a base 2.

Wherein the fixing device 1 is fixed on the sole. Preferably, the fixture 1 is made of stainless steel. More preferably, the fixing means 1 are made according to the size of the shoe. Wherein, the fixing device 1 can be bound on the shoe through a strap, and can also be fixed with the bottom of the shoe.

The base 2 is located below the fixing device 1 for contacting the ground. When walking or stepping down, the base 2 is in contact with the ground or a step surface. Preferably, the base 2 is also made of stainless steel.

This makes the fixing device 1 and the base 2 relatively durable on the one hand and convenient on the other hand for installing the elastic members of the tree.

In the present invention, a plurality of elastic members are provided between the fixing device 1 and the base 2. The elastic member is a telescopic load-bearing part, and the telescopic distance is about the height of one step. As shown in fig. 2, the elastic member is automatically and slowly retracted to a compressed state under the pressure of the weight of the human body. As shown in fig. 1, when the human body steps over the foot, the elastic member is automatically extended to the extended state.

The elastic member may be a spring. However, in the practical application process, the following are found: along with the compression of the spring, the resistance of the spring is larger and larger, the later half-stroke compression resistance is larger and larger, the stress of the spring is uneven, and the effects of saving labor and protecting knees are not good.

Therefore, in the present invention, preferably, the elastic member is a gas spring. Because the pressure of gas spring is linear, when pressure reaches its operating pressure, and begin the rapid compression, and keep the resistance unchangeable basically, and the compression process is more steady, is fit for realizing this neotype target function.

More preferably, two gas springs, a first gas spring 3 and a second gas spring 4, are arranged between the fixing device 1 and the base 2. By arranging the two air springs, the air spring does not shake left and right, and has good balance.

As shown in fig. 1 and 2, in the present invention, one end of the first air spring 3 is rotatably connected to the fixing device 1 through a first rotating shaft 5, and the other end is rotatably connected to the base 2 through a second rotating shaft 6. Meanwhile, one end of the second gas spring 4 is rotatably connected to the fixing device 1 through a third rotating shaft 7, and the other end thereof is rotatably connected to the base 2 through a fourth rotating shaft 7.

Like this, in the process of atress compression or relieving gravity resilience, first gas spring 3 and second gas spring 4's both ends can both for fixing device 1 and base 2 rotate, guarantee can not influence its shrink, and the equilibrium is better.

The inventor finds in practice that different gas springs should be used for different people. In particular, for children, the first gas spring 3 and the second gas spring 4 should have a length of 15-20cm and a supporting force of 10-20 kg. In this way, the weight of the child is also able to compress the gas spring. For adults, the length of the first gas spring 3 and the second gas spring 4 is 20-25cm, and the supporting force is 20-30 kg. Therefore, the weight requirement of adults can be met, and the purposes of saving labor and protecting knee joints can be achieved.

The working process of the lower step knee-pad shoe stretcher of the invention is described in detail with reference to fig. 3. For example, in the process of descending steps, the left leg is supported, the right leg is stepped out, and at the moment, the elastic component of the shoe stretcher below the right foot automatically extends out; when the right foot lands on the ground, the elastic member of the shoe stretcher below the right foot is slowly pressed down by the gravity of the person and gradually contracts until the elastic member contracts to the maximum compression state. Then, the right leg becomes a supporting leg, the left leg steps off the lower step, at this time, the elastic member of the shoe stretcher below the left foot automatically extends out, and when the left foot lands, the elastic member of the shoe stretcher below the left foot is slowly pressed down by the self gravity of a person and gradually contracts until the elastic member contracts to the maximum compression state. Thus, the support legs and the stepping-out and retreating are mutually alternated to realize the lower step.

When the user steps down, the elastic member of the shoe stretcher for stepping out the leg extends out, and the shoe stretcher is supported on the next step and then slowly compressed, so that the bearing of the supporting leg can be reduced, and the aim of saving labor is fulfilled. Meanwhile, when the weight center of the body shifts to step off the leg, the elastic component of the shoe stretcher is slowly compressed, so that the impact force on the knee joint can be reduced, and the aim of protecting the knee joint is fulfilled.

The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
