Description

Walker Support {WALKER SUPPORT}

The description below relates to the walker support. More specifically, the present invention relates to a device that connects a rotatable bearing and a connecting part to a walker, and connects a support leg to the connecting part to alleviate an impact applied to the walker when the walker comes into contact with a landmark.

People can use orthosis when body functions are weakened or body movement is not smooth due to body deformation. Among orthosis, in particular, a walker is one of the necessary devices for people with reduced mobility. Persons with reduced mobility include, for example, infants and the elderly. In the case of the elderly, the weight is higher than that of a newborn baby, so the elderly can be easily injured in a safety accident. When an elderly person with limited mobility uses a walker to move, if the walker gets caught in an obstacle or the elderly loses the center of gravity, it may lead to a serious accident. There is a need for a walker that can overcome the impact of obstacles and prevent shaking.

In this regard, Korean Patent No. 10-0859890 discloses an auxiliary walking device that prevents safety accidents and facilitates storage.

1 is a view showing the use of a walker support according to an embodiment.

Referring to FIG. 1 , the walker 1 may help a person with reduced mobility. For example, a person with reduced mobility may be an elderly person. The walker 1 may support the elderly and infirm so that they do not fall while walking, and may help the elderly to move safely. The walker 1 provides a handle that the elderly can hold, and the elderly can receive assistance in walking depending on the force supported by the walker 1 by holding the handle. As the walker 1 supports it, the elderly and infirm may be able to walk stably without falling down. The walker 1 may include a walker leg 10 , a wheel 11 , and a walker support 12 .

The walker leg 10 is a support connected to the ground direction on the lower side of the walker 1 and can support the walker 1 with respect to the ground. For example, a normal walker leg 10 may be composed of four on the lower side of the walker 1 . With the four walker legs 10 , the elderly can maintain a stable posture in all directions.

The wheels 11 may run on the two legs 10 of the walker in front based on the moving direction of the walker 1 . The wheel 11 can further improve the function of the walker 1 for assisting walking. For example, the walker 1 can move more smoothly in the moving direction of the walker 1 by the front wheels 11, and when the walker 1 is stationary, the rear wheels 11 are not installed. It is possible to efficiently assist the walking by supporting the walker leg 10 located in the .

The walker support 12 may include a connection part 120 , a bearing 121 , and a plurality of support legs 122 .

The connection part 120 may include a hollow in which the walker leg 10 is inserted. In a state in which the walker leg 10 is inserted into the hollow, the connection part 120 can freely rotate. For example, the hollow may include a cylindrical groove. Since the hollow includes a cylindrical groove, it is possible to prevent the occurrence of abrasion on the contact surface with the walker leg 10 even when the connection part 120 rotates with respect to the walker leg 10 . In addition, the hollow cylindrical shape may act to enable the connection part 120 to perform a more smooth rotational motion.

The connection part 120 may include a larger cross-sectional area than the bearing 121 based on a cross-sectional area parallel to the ground. The connection part 120 may be connected to the plurality of support legs 122 by including a large cross-sectional area. In addition, the moment of inertia due to the rotation of the connection part 120 increases, so that it is possible to further mitigate the impact when collided with an external feature.

The bearing 121 may be fixed to surround the walker leg 100 . Since the bearing 121 is fixed to the leg 10 of the walker, the connection part 120 connected to the bearing 121 may be fixed at a predetermined position of the leg 10 of the walker. The bearing 121 is disposed in the hollow and may be rotatable with respect to the connection part 120 with the walker leg 10 as a rotation axis. For example, the bearing 121 may include a spherical ball. In addition, the bearing 121 may include two rings having different sizes. The ball is positioned between the two rings so that the ball can move in a circumferential direction between the two rings. Through the circumferential motion of the ball, the ring on the outside can rotate relatively, and the connection part 120 connected to the outer ring can also rotate in the same direction as the outer ring. Therefore, the connection part 120 can rotate more accurately and smoothly about the rotation axis through the movement of the two rings and the ball, and the bearing 121 can reduce heat generation due to friction to prevent damage to parts.

The plurality of support legs 122 may extend from the lower side of the connection part 120 toward the ground and may be disposed at an isometric angle with respect to the walker leg 10 . For example, a plurality of four support legs 122 may be connected to the connecting portion 120 at an angle of 90 degrees to each other. The four support legs 122 positioned at the same distance from each other may change positions with each other through rotation of the connection part. Therefore, when the supporting leg 122 collides with a feature or obstacle, the position of the supporting leg 122 is changed. Even if the position of the supporting leg 122 is changed, when the walker leg 10 is shaken and tilted to one side, at least The two support legs 122 are positioned in an inclined direction to be in contact with the ground. That is, when the walker leg 10 is inclined at a predetermined angle with respect to the ground, at least a portion of the plurality of support legs 122 may contact the ground. As a result, the two support legs 122 in contact with the ground can support the walker leg 10 to prevent the walker 1 from falling.

2 is a side view of a walker support according to an embodiment.

Referring to FIG. 2 , the plurality of support legs 122 may be connected to the connecting part 120 so as to be inclined to the outside of the walker leg 10 . That is, when the walker support 12 is viewed from the side, the plurality of support legs 122 may be opened in both directions by taking the walker leg 10 as a center line as a reference. For example, the extension line in the longitudinal direction of the support leg 122 and the extension line in the longitudinal direction of the walker leg 10 may meet at one point. Each extension line meeting at a point may form an acute angle to each other. The acute angle may be a very small value, such as about 10 degrees.

Since the angle formed by the longitudinal extension line of the support leg 122 and the longitudinal extension of the walker leg 10 forms an acute angle, the plurality of support legs 122 are formed in a state in which the walker leg 10 is perpendicular to the ground. can be separated from That is, when the walker 1 is progressing without the leg 10 of the walker being inclined, the plurality of support legs 122 may be in a state not in contact with the ground. Accordingly, when the walker 1 is performing a role of assisting walking without a problem, the plurality of support legs 122 may not come into contact with the ground. This structure of the support leg 122 can prevent abrasion of the lower end surface of the support leg 122 in contact with the ground.

When the plurality of support legs 122 collide with an obstacle while the walker 1 proceeds in the moving direction, the impact received by the plurality of support legs 122 is transmitted to the connection part 120 to rotate the connection part 120 . can By rotating the connection part 120 , a part of the impact may be converted into rotational energy, and the walker 1 may be protected from impact by an obstacle. That is, the shock received by the walker 1 may be alleviated.

3 is a perspective view illustrating a state in which an elastic member is disposed at the lower end of the support leg according to the embodiment.

Referring to FIG. 3 , an elastic member for absorbing shock may be disposed at the ends of the plurality of support legs 122 adjacent to the ground. The elastic member for absorbing the shock may use a material having a stronger frictional force with the ground than the material of the general support leg 122 . By using a material having a strong frictional force, the plurality of support legs 122 can prevent sliding on the ground. In addition, by using a material having a strong frictional force, the plurality of support legs 122 can prevent the phenomenon that the plurality of support legs 122 cannot support the walker 1 with respect to the ground. The plurality of support legs 122 may include, for example, a horseshoe shape in which a rubber material is disposed on a contact surface with the lower ground. By disposing a rubber material on the contact surface of the support leg 122 with the ground, the friction coefficient of the lower end of the support leg 122 can be increased. In addition, when the walker leg 10 is inclined, the horseshoe shape increases the vertical drag received by the plurality of support legs 122 from the ground, and consequently, the frictional force acting between the plurality of support legs 122 and the ground. can be increased

4 is a perspective view showing a state in which the lower end of the support leg according to the embodiment is formed in the form of a sole.

Referring to FIG. 4 , the end of the support leg 122 in contact with the ground may be formed in the form of a sole. That is, the cross-sectional area of the support leg 122 may be wider as the support leg 122 faces the ground from the portion connected to the connection part 120 . For example, the support leg 122 has a portion in contact with the connecting portion 120 is made relatively thinner than the other support leg 122 portion, and goes toward the lower portion of the support leg 122 in contact with the ground along a round curved surface. The cross-sectional area can be manufactured to be wide. Accordingly, the contact surface of the support leg 122 and the ground may be wider. As the contact surface is widened, the frictional force between the lower portion of the support leg 122 and the ground may be increased.
