  However, it is indispensable for a person who cannot stand up by himself in such a walker to be assisted by the assistant until the person moves from a sitting posture to a standing posture where the walker can be used.

  For example, Japanese Patent Application Laid-Open No. 8-215250 discloses a device having such a function of assisting rising. This is constructed so that the elbow rest is driven up and down along a linear motion shaft that falls forward, and the elbow rest is provided with a grip portion and an operation portion and supports the back of the waist A support belt is adopted, and when the user grasps the grip part from the sitting posture and operates the switch, the armrest part rises diagonally forward, and in conjunction with this, the belt pushes out the waist, It is configured to assist the user in standing up.

  However, such a walker is large and costly, and when the position of the grip that is gripped moves forward and upward, the gripped user tends to be anxious about falling forward.

  The object of the present invention is to effectively solve these problems.

  In order to achieve this object, the present invention takes the following measures.

  That is, the stand-up assisting device of the present invention includes an elbow rest part and a grip part located in front of the elbow rest part, and the elbow rest part is set to a substantially horizontal normal use position with the vicinity of the grip part as a base point. By receiving an overload from this normal use position, it is possible to rotate between the standing auxiliary position that sinks to a predetermined angle against the elastic force.

  With this configuration, if the elbow rest is provided at a position that is easy for the user to use when standing up, the user in a sitting position will grab the grip and the elbow rest will sink to the standing assist position. The user can stand up comfortably while putting his elbow on the armrest and pulling the grip. At that time, since the pivot point of the elbow rest is in the vicinity of the grip, even if the elbow rest is rotated while gripping the grip, the position of the elbow on the elbow rest is difficult to shift and stable. You can start standing up. And after standing up, since an elastic restoring force acts on an elbow rest part, it can return to a normal use position appropriately. Moreover, since it stands up so that the fixed grip part may be drawn, a sense of security can be obtained. Furthermore, if this stand-up assisting device is used opposite to the above, it can be effectively used as a seating assisting device.

  In order to appropriately switch between the moving state and the standing / sitting state, it is necessary to selectively prohibit rotation of the elbow rest part of the arm rest part at or near the normal use position. It is desirable to further include an operation part of a lock mechanism.

  In order to further reduce the load applied when standing, it is preferable to further include a knee pad at a position below the elbow rest.

  In order to construct a self-supporting walking support device that is movable, can be easily seated and erected at any position, and is simple and extremely easy to use, a recess that is supported by a caster and into which a user can enter It is preferable to attach an elbow rest part and a grip part that constitute a standing assisting device to the standing part of the apparatus main body having a base part having a standing part and a standing part rising from the front of the base part.

  According to the present invention described above, the elbow rest can basically be rotated so as to sink into the user side, and only the grip portion is provided in the vicinity thereof. It is possible to provide a stand-up assisting device and an independent walking support device that can appropriately assist a person's standing / sitting operation and walking operation and reduce the burden on the user and the assistant.

An elbow support 14 made of pipe material is provided, and the elbow support 1 is supported by the movable bracket 13 and the elbow support 14.

  On the other hand, the self-supporting walking support device B is a device in which the rising assist device A is incorporated in the device main body 3 having a configuration in which the rising portion 34 is raised from the base portion 33 supported by the casters 31 and 32.

  The base part 33 of the apparatus main body 3 is a series of pipe legs made of a pair of base legs 33a, 33a extending in the front-rear direction and a base leg connecting part 33b connecting the front end sides of the base legs 33a, 33a. The front caster 31 includes a front carry-out portion formed at the left and right ends of the base leg connecting portion 33b and a rear end portion of the base leg 33a. And supported by a rear caster 32. The front caster 31 is a swing type, the rear caster 32 is a fixed type, and the front caster 31 has a lock function for locking the rotation. The rear caster 32 has a smaller diameter than the front caster 31. Things are used. The rear caster 32 is set to a size that is low enough to allow the rear caster 32 and the rear end region of the base leg 33a to enter under the bed.

  The upright portion 34 is a pillar-shaped member made of a pipe material, the base end is fixed to two central portions of the base leg connecting portion 33b via the mounting bracket 34a, and is slightly rearward so as to approach the user toward the upper end side. It is inclined to the slope. An elbow support 35 that supports the elbow rest member 1 is attached to the upper end of the standing portion 34. The elbow support 35 includes an upward channel-shaped fixing bracket 36 including a bottom plate 36 a and a pair of side plates 36 b, and a reaction force mechanism 37 provided on the bottom plate 36 a of the fixing bracket 36. The reaction force mechanism 37 includes a plurality of spring insertion portions 37a that are erected in a plurality of rows and columns, and a coil spring 37b that is an elastic body that is erected in a state where the base end is inserted into the spring insertion portion 37a.

  Thus, in the present embodiment, the movable bracket 13 is placed on the fixed bracket 36 so that the side plate 13b of the movable bracket 13 is positioned outside the side plate 36b of the fixed bracket 36, and the fixed bracket 36 is positioned at a position close to the grip portion 2. The side plate 36 b and the side plate 13 b of the movable bracket 13 are connected by the horizontal axis 4. As a result, the elbow rest member 1 is in a relationship in which the lower surface of the top plate 13a of the movable bracket 13 is supported by the upper end of the coil spring 37b, and the elbow rest portion 11 is substantially horizontal when not receiving an overload as shown in FIG. The normal use position 11P can be rotated between the normal use position 11P and the standing assist position 11Q that sinks to a predetermined angle while compressing the coil spring 37b by receiving an overload from the normal use position 11P. The upper edge of the side plate 36b of the fixed bracket 36 is inclined, and when the elbow mount 11 sinks to a predetermined angle, the top plate 13a of the movable bracket 13 hits the upper edge of the side plate 36b of the fixed bracket 36 and sinks further. Is prohibited. Conversely, when the elbow rest 11 is lifted upward, the center of gravity of the elbow rest member 1 rotates to the retracted position 11R beyond the axis of the horizontal axis 4 as shown in FIG. 4, and the top plate 13a of the movable bracket 13 is fixed. When the armrest 11 stops when it interferes with the rear edge of the side plate 36b of the bracket 36, the reaction force can be easily adjusted. The armrest portion 11 when in the normal use position 11P is set to a height position that is easy for a user with an average physique to use in a standing posture. Of course, the upright portion 34 can be extended and contracted to have a height adjusting function according to the user.

  Further, in the present embodiment, as shown in FIG. 2 showing the back side of the elbow rest portion 11 in FIG. 1, the elbow rest portion near the elbow rest portion 11, specifically, a part of the elbow rest portion 35. 11 is provided with an operation unit 51 for selectively prohibiting the rotation of 11. The operation unit 51 constitutes the lock mechanism 5 (not shown in drawings other than FIG. 2) together with the lock shaft 52, and the lock shaft 52 is provided at one side plate 36b of the fixing bracket 36 and at a position facing it. The operation portion 51 is provided integrally with the lock shaft 52 so as to protrude forward (on the opposite side of the user) from the lock shaft 52. A restriction hole 13c is provided at a position corresponding to the lock shaft 52 in one side plate 13b of the movable bracket 13, and the operation portion 51 is moved when the elbow rest portion 11 is at the normal use position 11A shown in FIG. By operating and inserting the lock shaft 52 into the restricting hole 13c, the rotation of the movable bracket 13 and thus the elbow placing member 1 is prohibited. By operating the operating portion 51 and extracting the lock shaft 52 from the restricting hole 13c, the elbow placing member 1 is removed. The rotation is allowed.

  In addition, as shown in FIGS. 7 and 8, the present embodiment further includes a knee pad portion 6 at a position below the elbow rest portion 11. The knee pad portion 6 is fixed to a part of the apparatus main body 3, in this embodiment, a horizontal can 38 b of the handrail 38, and a cushion material 62 is attached to a base material 61 arranged in an attitude that is at an elevation angle on the user side. It is configured by pasting. The knee pad portion 6 may have a structure that can be stored in an unobstructed position on the apparatus main body 3 by an appropriate structure.

  Finally, as shown in FIGS. 4 and 5, a cover 7 that encloses the horizontal bracket 4 with the fixed bracket 36 and the movable bracket 13 is provided between the elbow rest member 1 and the upright portion 34. It is preferable. In this case, the operation unit 51 is provided so as to protrude from the cover 7 and not interfere with the operation.

  The self-supporting walking support apparatus B of the present embodiment configured as described above is weight-weighted with the user placing his elbows on the left and right elbow rests 11 at the normal use position 11P and holding the grip 2 by hand. You can leave and move. And the standing assistance instrument B is provided with the elbow rest part 11 and the grip part 2 positioned in front of the elbow rest part 11, and the elbow rest part 11 is set to a substantially horizontal normal use position with the vicinity of the grip part 2 as a base point. Since the stand-up assisting device A that can rotate (rotate) between 11P and the stand-up assist position 11Q that sinks to a predetermined angle against the elastic force by receiving an overload from the normal use position 11P is shown in FIG. When the user C in the sitting posture shown in FIG. 7 reaches the grip part 2, the elbow rest part 11 sinks flexibly to the standing support position 11Q, and the user attaches an elbow to the tilted elbow rest part 11 and grips 2 8 can be easily raised in a natural posture to the standing posture shown in FIG. 8 with the elbow as a fulcrum. At this time, since the pivot base point of the elbow rest portion 11 is in the vicinity of the grip portion 2, even if the elbow rest portion 11 is rotated when trying to grip the grip portion 2 through the elbow rest portion 11, the elbow rest portion 11 is not likely to cause elbow misalignment, and can stand up stably. And since the elastic restoring force acts on the elbow rest part 11 after standing up, the elbow rest part 11 can return to the normal use position 11P appropriately. Moreover, since it stands up so that the fixed grip part 2 may be pulled, there is no sense of falling forward and a sense of security can be obtained. Further, if the rise assisting device A is used in reverse, the user C's shoulder is elastic because the user C changes the standing posture shown in FIG. 8 to the seating posture shown in FIG. The burden on the patient (such as fractures and dislocation due to osteoporosis) can be reduced, and it can be effectively used as a sitting assistance device. Of course, even if the assistant assists the standing / sitting operation, the burden on the assistant can be greatly reduced as compared with the conventional case.

  In the above, the elbow rest portion 11 of the present embodiment has a cushioning property, and the bank portion 1b is formed on the outer peripheral portion and the inner peripheral portion. It becomes a more preferable state where the fulcrum of the elbow is fixed. In addition, since the grip portion 2 is positioned on the extension line of the forearm portion when the elbow is placed on the elbow placement portion 11, it is easy to grasp and easily apply force.

  In this embodiment, the elastic force can be adjusted according to the physique and physical strength of the user by the set position and number of the coil springs 37 b constituting the reaction force mechanism 37.

  Furthermore, since the handrail 38 is also provided on the lower side of the elbow rest 11 in the present embodiment, the handrail 38 can be held up and seated, and the forearm can be placed on the elbow rest 11 while standing. Various uses such as the operation of extending the part and gripping the grip 2 or the reverse operation are also possible.

  And this embodiment is further provided with the operation part 51 of the lock mechanism 5 for selectively prohibiting the rotation of the elbow rest part 11 in the vicinity of the elbow rest part 11 in the normal use position 11P. When the user or the assistant who has completed the operation of the operation unit 51 in the locking direction, the user can be placed in a state where the body can be stably placed in the elbow support unit 11 and the user or the assistant can move. By operating the operation unit 51, it is possible to easily switch to a state where seating is assisted.

Further, since the knee pad portion 6 is provided below the elbow rest portion 11, if the grip portion 2 is pulled in a state where the knee of the user in the sitting posture is abutted against the knee pad portion 6, it is physical therapy. Thus, it is possible to reduce the burden on the knee and realize a state in which the user can easily stand up.

  And it has the base part 33 which has the recessed part S2 which is supported by the casters 31 and 32 and a user can approach with respect to the above-mentioned stand-up auxiliary instrument A, and the standing part 34 which stands up from the front of this base part 33 Since the standing part 34 of the apparatus main body 3 is attached with the elbow rest part 11 and the grip part 2 constituting the standing assist device A to constitute the self-supporting walking support apparatus, it is movable and can be seated and raised at any position. It is possible to simply configure an easy-to-use independent walking support device B that can easily perform the above.

  The specific configuration of each unit is not limited to the above-described embodiment.

  For example, the reaction force mechanism is not limited to one using a spring, and other elastic / expandable functions such as rubber and damper may be employed.

  In the above embodiment, the elbow rest is configured to perform a rotation operation with the horizontal axis as a fulcrum. However, the elbow rest may be configured to move toward the user as the elbow rest sinks. I do not care.

  Furthermore, in the above embodiment, the operation part of the lock mechanism is provided so as to protrude forward (opposite to the user). However, the operation part of the lock mechanism may be provided so as to protrude on the user side. You may provide in the part side.
