(2) Since the pillar is constructed in the center of the closed side of the base frame, the pillar does not get hurt by hitting the surroundings when walking. (3) When not in use, the other Φ walking aids can be pushed into the stacked form from the open side of the base frame, so that no space is required for storage. The effect. [Problem to be Solved by the Invention] However, in the above-described walking aid, in addition to the cushioning member, since the grip portion is composed of other parts, the number of parts is increased. Further, since the cushion member is a specification for adhering the artificial leather to the plywood, there is a problem that the upper side is heavy and the center of gravity is high, so that the stability of the entire walker is lowered. Further, when artificial leather is used as the skin of the cushioning member, it may be damaged by contact with a wall or the like. In order to improve the above-described problems, the present invention provides a method in which the reclining portion is formed by resin integration, and the weight is reduced, and the number of parts can be reduced, and the stability of walking can be improved. The cushioning member placed on the abutment portion is detachably mounted and can be repaired. -5) 1360415 The above-mentioned base frame 2 is composed of a straight horizontal leg tube 2a and a pair of longitudinal leg tubes 2b, 2b' The one end side is integrally joined to both ends of the leg tube 2a, the other end side is expanded more than the interval between the one end portions, and the pair of longitudinal leg tubes 2b and 2b are integrally connected. It is comprised as the base frame member 2c for mounting pillars 3. The longitudinal leg tubes 2b, 2b are bent at predetermined positions on both end portions, and are set to have a predetermined interval from the ground contact surface. φ Then, the caster casters 6 are attached to both end portions of the above-described lateral leg tubes 2a and the other end portions of the pair of longitudinal leg tubes 2b and 2b, respectively. Further, suitable protective cushioning members P may be provided at appropriate positions of the base frame 2, for example, at both end portions of the lateral leg tube 2a, or at an intermediate portion of the pair of longitudinal leg tubes 2b and 2b, and the walking casters 6. . The pillar 3 is erected at a center portion of the base frame member 2c, and is formed to have a slightly inclined shape toward a center portion of the pedestal 2. Further, although the above-described strut 3 is not provided with a pattern, a pneumatic spring in which the above-described adjustment stay 4 is fixed without a segment and the support portion 5 is fixedly supported is provided. The gas spring is constructed by operating the operation lever 7 provided on the front surface of the upper portion of the adjustment column 4, and the adjustment column 4 can be adjusted up and down without a step. Next, the abutting portion 5 is provided with a concave portion 8 for accommodating the user's body at the center portion, and the stable holding member 9 projecting on the front side of the concave portion is formed using a known synthetic resin, and the upper side of the concave portion 8 is provided on the upper side. An integral blow molded body of the armrest portion for the elbow is placed (see Fig. 3, Fig. 4, and Fig. 5). -10- (8) 1360415 In other words, as shown in Fig. 3, the abutting portion 5 is formed to have a wide upper central portion 5a which is substantially flat, and a rear portion from the both sides of the central portion 5a to the rear portion. The shape of 10 is made, and the above-mentioned recess 8 is drawn in the center area. Then, on the upper surface of the center portion 5a and the upper surface of the armrest portion 10, a plurality of engaging holes h for engaging the engaging members for the cushion member to be described later are formed at appropriate intervals. The stable grip member 9 is formed in a curved shape which is inclined upward from the center portion 5a φ of the reclining portion 5 and is formed to have a predetermined diameter. At the root portions of the center portion 5a of the stable holding member 9 which are close to each other, handle portions G and G which are curved in a symmetrical shape so as to be easily grasped by the user are provided. On the other hand, a convex portion K that protrudes forward in a convex shape is provided at a central edge of the front surface portion of the central portion 5a of the abutting portion 5, and a concave curved portion is formed at a central portion of the opposing spike holding member 9 The concave portion C is formed such that the distance between the concave portion C and the convex portion K of the central portion 5a is narrower than the distance between the abutting portions of the handle portions G and G of the both sides, and the spaces S and S are formed. Further, the armrest portion 10 has a size that forms an elongated shape in which the elbow can be placed, and an offset drop preventing portion 11 that is formed higher than the upper surface of the recessed portion 8 is provided on the outer edge. Next, the description will be given of the description of the cushioning member 12 attached to the abutting portion 5. As shown in Figs. 2 and 7, the cushioning member 12 is a first cushioning member 12a attached to the central portion 5a of the abutting portion 5, and It is composed of a second cushioning member 12b that is attached to the hands 10 and 10 of the two support -11 - (9) 1360415. Of course, the configuration of the cushioning member 12 is not limited thereto, and may be constituted by a single cushioning member. Further, the cushioning member may be attached only to the two armrest portions 10, 10. The material of the cushioning member 12 described above can be constructed of a conventional soft material. Then, on the back side of the cushioning member 12, an engaging convex portion as the engaging means 13 is provided. The engaging convex portion is formed so as to have the same number of turns and the same interval as the engaging holes h formed on the upper surface of the central portion 5a of the leaning portion 5 and on the upper surface of the armrest portion 10. The engagement hole h is formed by a through hole formed when the abutment portion 5 is molded. The engaging hole h is an upper hole h1 whose inner diameter is slightly smaller than the outer diameter of the engaging convex portion, and a lower hole h2 which is larger than the inner diameter of the upper hole h1. At this time, the upper hole hi is slightly larger than the inner diameter at the center (refer to Fig. 6). Further, the front end of the engaging convex portion is formed to be slightly larger than the inner diameter at the center of the upper hole hi. The above is an example of the engaging means 13, and the other buckles can be used, and another Φ can be used (the drawings are omitted). Further, as the engaging means 13, a fitting portion of a horizontally long fitting portion may be formed on the back surface of the cushioning member, and a horizontally long fitting recess portion corresponding to the fitting convex portion may be provided on the upper surface side of the leaning portion. (The figure is omitted). In the walking assist device 1 having the above configuration, the user moves from the other end side of the pair of longitudinal leg tubes 2b and 2b on the open side of the base frame 2 to the recessed portion 8 at the center of the base frame 2, and leans the body toward the body. The concave portion 8 of the portion abuts the body so as to be close to the handle portion G, G of the stable holding member 9 which is inclined upward from the central portion 5a of the reclining portion 5, and can be pushed -12 - (10) 1360415 Move the walking aid 1 while walking. Since the handle portions G and G of the stable holding member 9 are protruded into a mountain shape at the root portion of the center portion 5a of the abutting portion 5, it is possible to correspond to the user's physique or the condition of the injury, even if it is easy to grip. The position of the grip is different, and the user can easily hold the grip portion G, G which is easy to hold. Further, even when the pedestal 2 is in contact with the surrounding wall or the like during walking, it can be provided at both ends of the lateral leg tube 2a, or at the intermediate portion of the pair of longitudinal leg tubes 2b, 2b, and the walking caster 6 A suitable protective cushion member P is used to prevent damage. Even when the leaning portion 5 hits an obstacle such as a wall, since the leaning portion 5 is formed of a resin integrally molded, it is not damaged. If the height of the reclining portion 5 is not suitable, the gas spring can be used to release the fixed state of the gas spring by operating the adjusting rod 7 on the upper front side of the strut 4, and the adjusting strut 4 is moved up and down to change the leaning portion 5 The height of the support. Since the height of the reclining portion 5 can be freely adjusted as described above, the physique and condition of the user can be matched as shown in the figures 9 to 11, and when the user is in a long-term convalescence condition, it is suitable as a walking rehabilitation training. machine. For example, in the ninth figure, the user is in an elderly state, or the state of use is serious when the injury state is serious. In this case, the user can place the elbow on the armrest portion 10 of the abutment portion 5, Support the body. At this time, the cushioning member 12 on the reclining portion 5 acts properly, and when the user leans hard, it can be supported without pain. Further, since the armrest portion 10 is provided with the offset fall preventing portion n whose outer edge is higher than the upper surface of the recess portion 8, the elbow can be prevented from slipping. As described above, in the case where the user places the elbow on the hand wiping portion 10, the hand can be easily configured to the bottom-up inclined stable holding member 9 which is inclined upward from the central portion 5a of the reclining portion 5, On the other hand, the handle portions G and G of the stable grip member 9 can be moved while walking the walking assist device 1 while walking. • If the user is weak in grip strength or the arm is not free, the user will tilt forward and tilt the two hands from the handles G and G. At this time, even if the two arms pass through, they are stable. When the space S'S'' of both the grip members 9 is dropped to the front lower side, since the width of the stable grip member 9 is smaller than the width of the reclining portion 5, the arms are blocked by the spaces S, S' in the middle. The upper body can be supported in a state where it will not fall forward (refer to Figure 12). In addition, even in the case of a petite and inconvenient user, both hands are lowered from the space S, S' to the front and the front before holding the handle portions G, G, 'because of the stable holding member 9 The central portion constitutes the concave curved portion C' so that it can protect and avoid the collision of the stable grip member 9 near the face or throat. 保管 The storage of the walking aid 1 when not in use can be obtained from the base frame 2 of the previous walking aid 1 On the rear side, the base frame 2' of the next walking assistor 1 is pushed, and even if the walking assistors 1 overlap each other, the movable support 4 of the previous walking assistor 1 will just come to the rear of the walking aid 1 Stabilizing the central portion of the concavely curved portion of the grip member 9, so that the holding member 9 is not obstructed, but can be stored in a state of being overlapped with each other, and the storage space can be reduced ( Refer to Figure 13). Further, when the cushioning member 12 on the leaning portion 5 is dirty due to use, the cushioning member 12 can be removed and simple cleaning can be performed. When the cushioning member 12 is to be detached, the engaging convex portion of the engaging means 13 of the cushioning member 1 can be pushed upward from the side of the lower hole h2 of the engaging hole h from the back side of the abutting portion 5 (refer to Figure 8). In the above, the walking assist device 1 has been described as an example. However, the reclining portion 5 is provided with a recess 8 for accommodating the user's body at the center portion, and is formed on the front side of the recess by using a conventional synthetic resin. The stable holding member 9 and the blow molded body integrally formed with the armrest portion 1 of the elbow placed on the upper side of the concave portion 8 are provided, so that the number of parts can be reduced, the weight can be reduced, and the center of gravity can be made Lower than the known walking aids and improve the stability of the walking aid. Further, although the cushioning member 12 is provided in the above-mentioned leaning portion 5, the #reliating portion 5 may be configured to not require the cushioning member 12. However, at this time, the material of the leaning portion 5 must use a material which is easy to absorb impact or slip.
