Description

  The present invention relates to a walking device for a welfare device.

Technology background

  Conventionally, walking tools or walkers for welfare equipment are usually tripod or quadruped frameworks, and there are walking cars with wheels and walkers without wheels, and a handle or armrest-shaped framework is used. It grasps, holds the body position depending on it, and assists the walking motion.

  Conventional walking implements hold a body by holding a handle or an armrest-shaped framework by hand in order to assist a walking operation, and therefore, the upper limb is fixed to the framework, and mainly walking only on the lower limb. In normal walking movement, when performing normal weight movement alternately left and right with flexion and extension of the lower limb, in order to correct the imbalance due to the movement of the center of gravity of the body position, the interaction and antagonism of the muscle force of each part of the whole body With, especially the movement of the upper limb, in conjunction with the movement of the lower limb, control the balance of the body position, as a movement to promote the movement of the center of gravity, has an important role in walking, but in general walking tools, There is a tendency to be overlooked relatively, and the present invention has been made in view of such problems in the prior art, and has as its object the purpose of a frame for a walking implement having wheels. Suspended on both sides A walking tool contributing to assist walking and recovering the walking function by interlocking the upper and lower limbs with the upper and lower limbs by swinging the stick alternately in the same way as normal walking. It is intended to provide.

  In order to achieve the above object, in the walking device of the present invention, casters are provided near the front ends on both sides of the frame of the trapezoidal framework, rear wheels are provided near the rear end, and support bearings are provided in the middle of the frame. The sliding cylinder is swingably supported, and the middle of the pair of walking sticks is freely slidably inserted into the sliding barrel.A handle is provided at the top of the walking stick, and a slipper is provided at the lower end thereof. A spring is interposed between the walking stick and the sliding cylinder to support the weight of the walking stick and the slipper while maintaining the gap between the slipper and the floor surface. At the same time as swinging the upper limb backwards with the handle of the walking stick, without applying pressure on the slippers, it floats up from the floor by the support force of the spring and steps forward, moves the weight forward and obtains the forward force, With the handle of the other walking stick At the same time as swinging the upper limb forward, stepping on the slipper against the support force of the spring, stepping backward on the floor surface, receiving the reaction force of the forward force, walking the walking stick alternately on both sides An operation is performed.

  Since the present invention is configured as described above, it has the following effects.

  The walking tool of the present invention supports the middle of a walking stick having a handle at the top and a slipper at the lower end, and when one handle swings backward with the upper limb, the swing around the bearing of the stick sliding cylinder. When a dynamic moment is obtained and the slipper and the lower limb part are lifted off the floor and swung to the forward side, the so-called stepping action moment is augmented, and when the other handle is swung to the forward side together with the upper limb, the slipper is moved to the lower limb. In the so-called stepping action, in which the foot is pressed rearward by stepping on the part, the swinging moment of the handle and the upper limb around the bearing of the walking cylinder of the walking stick is the moment of the slipper and the lower limb around the same bearing. To supplement the muscle strength of the lower limb side, and in both the stepping and the stepping motion, the lower limb movement can be assisted, and the normal walking motion and As can be accompanied by displacement of the upper limb side and leg side to maintain a balanced, repeats the walking motion on both sides alternately performing a smooth weight shift.

  And, as described above, the upper limb side movement assists the lower limb side walking movement, and the upper limb side and the lower limb side move by interlocking the upper limb and lower limb movement by the swinging operation of the walking stick. Can be used as a welfare tool, and can assist the walking motion and promote the effect of recovering the walking function.

  As described above, it is possible to provide a safe and inexpensive walking device that employs a simple swing operation mechanism of a walking stick, has a simple and lightweight configuration.

  An embodiment of the invention will be described with reference to the drawings based on an example. Referring to FIGS. 1 to 5, casters 2 are arranged near the front end on both sides of a frame 1 of a trapezoidal framework, and rear wheels 3 and 3 are arranged near a rear end. The bearings 4 and 4 are attached to the middle of the frame to support the sliding cylinders 5a and 5a in a swingable manner. At the top of the stick, handles 6 and 6 are attached at the top and slippers 7 and 7 are attached at the lower end to maintain the gap c between the slipper and the floor between the stick and the sliding cylinder. In order to support the weight of the walking stick and the slipper, a spring is interposed between the upper and lower limbs together with the handle of one walking stick while standing on the slipper. Floating from the floor surface by the support force of the spring without applying Step forward, move the weight forward to gain forward force, swing the upper limb forward together with the handle of the other walking stick, and simultaneously depress the slipper against the supporting force of the spring and step backwards on the floor. In response to the tension and the reaction force of the forward force, the walking motion is performed by alternately swinging the walking stick on both sides.

  As shown in FIG. 1, when standing on the slipper 7 and resisting the spring 8 when a tread-like load is applied, the slipper 7 comes into contact with the floor surface, and alternately moves on both sides with the same load and the handle 6 and The walking operation is performed by swinging the slippers 7 in opposite directions to each other, and the walking stick 5 performs the reciprocating swing by obtaining the operating force from both the handle 6 and the slippers 7, that is, the swing moment. At this time, by lifting one slipper side and performing a so-called stepping operation forward, the center of gravity of the weight is moved forward and downward to generate a forward force, and the other slipper side is controlled by a so-called stepping operation. In addition to supporting the reaction force of the forward force, the operation immediately shifts to the forward stepping operation, and the walking operation is repeated by alternately performing the stepping operation and the stepping operation on both the left and right sides.

  When performing the stepping-out operation while floating on the slipper 7 side, the slipper is separated from the floor surface by assisting the floating by the upward biasing of the spring 8, and the slipper counters the forward force by the so-called stepping operation in the rear direction. While supporting the force, the slipper is pressed against the floor against the upward bias of the spring 8 by the same reaction force or stepping pressure.

  The swinging moment when swinging the walking stick 5 on one side and swinging the handle 6 to the forward side together with the upper limb is such that the slipper 7 is stepped on the floor surface rearward by the extension of the lower limb, that is, so-called stepping When the swinging moment of the sliding cylinder around the bearing 4 in the operation is increased, the muscle force on the lower limb side is assisted, and when the handle 6 on the other side is swung back with the upper limb in the back direction, the rotation around the supporting bearing of the walking stick is also possible. The swinging moment of step S1 increases the swinging moment in the operation of stepping on the slipper 7 side to the forward side together with the lower limb portion. In both the stepping and stepping-up operations alternately performed on both sides, the upper limb side operation causes In addition to assisting in the movement of the gait, the weight is moved smoothly, almost in the same way as the normal walking movement, the balance is maintained with each other according to the interlocking of the upper limb and the lower limb, and the walking movement is repeated rhythmically To.

2, the length H of the walking stick 5, the swing range Lh of the handle 6, and the swing range Lf corresponding to the step length of the slipper 7 are set in accordance with the use conditions in the diagram showing the operation outline of the walking stick 5 in FIG. Then, when stepping on the swing range Lf / 2 corresponding to a half step, the length h1 of the stick 5 from the support 4 to the slipper 7 and the length h2 of the stick 5 from the support 4 to the handle 6 are several. There is a relationship of 1 and the height h above the floor of the support 4 of the sliding cylinder is obtained by Expression 2.

Number 2

h = {h1 ² − (Lf / 2) ² } ^1/2

  Here, as an embodiment, the length H of the walking stick 5 is 750 mm, the swing range Lh of the handle 6 is 350 mm, the swing range Lf corresponding to the step length of the slipper 7 is 300 mm, and 1 / Lf of Lf from immediately below the sliding cylinder 5a. When the foot is stepped by 2, that is, 150 mm, the stick length h1 from the support bearing 4 to the slipper 7 is obtained by Expression 3, and the floor height h of the support bearing 4 is obtained by Expression 4.

Number 3

              h1 = 750 × 300 / (350 + 300) = 346.2 (mm)

Number 4

h = (346.2 ² −150 ² ) ^1/2 = 312 (mm)

  As described above, the height h above the floor of the support bearing 4 can be set with respect to the length H of the walking stick 5, the swing range Lh of the handle 6, and the swing range Lf corresponding to the stride length of the slipper 7. Therefore, the length of the walking stick 5 and the height h above the floor of the support bearing 4 may be adjusted according to the user's physique, swing width of the upper limb, stride length of the lower limb, and physical condition.
