Description

The present invention relates to a runner capable of running smoothly even when a load is applied, and a set (a rail and / or a ket of a runway forming member) provided with the runner.

A runner is placed on a rail attached to the ceiling surface or the space on the ceiling side so that the runner can run, a body carrying device is attached to this runner, and a user such as an elderly person or a physically handicapped person who holds this body holding device. Devices have been proposed to assist people in their homes and facilities.

For example, Japanese Patent Application Laid-Open No. 2006-26254 (Patent Document 1) describes a traveling rail having a C-shaped cross section attached to a space on the ceiling side, a traveling means that can move along the traveling rail, and the traveling means. Describes a moving device for elderly people, etc., which is provided with a connecting rod held downward and a long pipe-shaped handrail that is fitted and detached along the outer peripheral surface of the connecting rod in the longitudinal direction and vertically hung vertically. Has been done. In this document, traveling means are described on a support shaft, a disk-shaped runner body rotatably attached to the support shaft around the support shaft, and a bottom peripheral edge and a side edge of the disc-shaped runner body. It is equipped with a plurality of attached ball casters and anti-slip means attached to the top plate of the disk-shaped runner body, and can be loosely fitted into the recess of the traveling rail so that it can slide in a predetermined position on the traveling rail. It is described that the T-shaped branching mechanism attached to is capable of changing direction and branching. Furthermore, in this document, even if the posture of the walking user tilts back and forth and left and right, and the body holding device also tilts in conjunction with the movement, the disk supported by the support shaft connected to the connecting rod. A corner of the peripheral edge of the top plate of the runner body collides with the ceiling side of the running rail to cause a stopper action, and the anti-slip means comes into contact with the ceiling side of the running rail to cause a stopper action. It is stated that the user's fall accident is prevented.

However, since it is equipped with multiple ball casters, not only is the disc-shaped runner body easy to slide on the running surface just by moving the traveling means a little, but the runner body is unstable when a load is applied. It is easy to slide in the front-back direction of the rail in a good condition. Therefore, if the user is in a posture of excessively tilting back and forth and left and right (for example, falling), the runner body may slide and the user may not be able to walk stably while maintaining balance. On the other hand, if the plurality of ball casters are removed to reduce the runnability of the runner, a large force is required for walking, and it becomes impossible to walk smoothly.

Further, at the branching portion where the traveling rail branches into a substantially T-shape, the user must move to this substantially T-shaped intersection, then change the direction and move in a smooth direction. I can't convert. In particular, in the process of changing the direction, the support shaft of the traveling means easily contacts and locks the corner portion of the branching device, so that the user, especially the elderly, cannot change the direction smoothly.

Rails and runners are also used in fields such as shielding of predetermined spaces, partitioning (opening and closing), transfer of goods, and transportation. According to Japanese Patent Application Laid-Open No. 2003-250694 (Patent Document 2), a shaft portion inserted between rails of a curtain rail is horizontally rotatable or integrally connected to the upper end of the shaft portion, and is inside the rail. Described is a suspension runner provided with a traveling portion locked to the upper surface of the rail and a suspending portion that is horizontally rotatably connected to the lower end of the shaft portion and for suspending a suspended object. .. In this document, the lower surface of the traveling portion in contact with the rail is formed in a spherical or curved shape with the center portion as the center, and when moving the curved portion of the curtain rail, the traveling portion rotates horizontally to displace the direction. It is also stated that. In the runners described in this document, at least the suspended portion is rotatable in the horizontal direction relative to the shaft portion.

However, this runner also has a small contact resistance between the running portion and the rail and is slippery on the rail, so that the user may not be able to walk stably while maintaining a balance. Therefore, when the runner is connected to the body holding device worn by the elderly or the like, the hanging runner cannot be moved to follow the movement of the center of gravity of the elderly. Further, in the branch portion where the rail is branched in a T-shape or the like, the shaft portion of the runner is easily caught in the branch portion, and even if the elderly person tries to change the direction in a predetermined direction, the suspended runner moves due to the elderly person's movement. I can't keep up and I can't change direction smoothly.

Japanese Patent Application Laid-Open No. 2006-26254 (Claims, [0010], [0025] to [0032], [Fig. 6], [Fig. 8]) JP-A-2003-250694 (Claims, [0012], [Fig. 1] to [Fig. 4])

Therefore, an object of the present invention is to provide a runner capable of running smoothly and stably even when a predetermined load is applied, and a set (a set of a rail and / or a runway forming member) provided with the runner. There is.

Another object of the present invention is to provide a runner capable of smoothly and stably running by following (or following) the movement of a user without excessive gliding, and a set including this runner. ..

Another object of the present invention includes a runner (for example, a runner for a walking or movement assisting device) useful for assisting the movement of a user who has difficulty walking such as an elderly person or a physically handicapped person, and this runner. To provide a set.

As a result of diligent studies to achieve the above problems, the present inventor has applied the running wall to the shaft member of the runner in a rail in which a plurality of running walls are extended at different height positions from the facing inner wall portions. When a plurality of rotating members that can rotate in contact with the traveling surface are attached, the rotating members rotate while contacting the traveling surface, and the runner runs smoothly, and the rotating members rotate in opposite directions on the plurality of traveling walls. However, since the runner does not slide excessively and the rotating member can be supported by a plurality of running walls, it has been found that the runner runs smoothly and stably even when a predetermined load is applied, and the present invention has been completed. ..

That is, the runner of the present invention includes a traveling unit that can travel along the slit-shaped opening of the rail, and the traveling unit includes a shaft member that can be slidably arranged in the slit-shaped opening and the shaft member. The shaft member is provided with or attached to the shaft member at predetermined intervals in the axial direction, and is provided with a plurality of rotating members that are in contact with the traveling path of the rail and are rotatable in the circumferential direction of the shaft member; the plurality of the traveling units. The shaft members of the above are attached to the mounting members at predetermined intervals in the traveling direction of the runner.

A rotating member that can rotate in the circumferential direction of the shaft member may be attached to the shaft member located between the plurality of rotating members and / or the shaft member located at the slit-shaped opening.

In such a runner, since a plurality of rotating members are attached to the shaft members at intervals, they are supported by the running surface at different parts in the axial direction of the shaft members, and are supported by the running path (running surface) of the rail. Each rotating member can rotate in contact (rotatable in the opposite direction). Therefore, even if a predetermined load is applied, the vehicle can run stably and smoothly, and does not slide excessively. Further, since a plurality of shaft members are attached to the mounting members, the following rotating members can be rotated to travel by following (or following) the preceding rotating member, so that the vehicle can smoothly travel along the traveling path. Can be done. For example, even if the traveling path is branched, even if the leading (or leading) rotating member tries to move or guide in the wrong direction at the branching portion, the succeeding rotating member is located on the user side, so that the following rotating member is located. The direction of travel can be corrected or corrected by the rotating member, the vehicle can travel smoothly, and the direction can be changed smoothly.

More specifically, a pair of ball bearings as rotating members are attached to the shaft members at predetermined intervals in the axial direction; a shaft member located between the pair of ball bearings and / or a shaft located in a slit-shaped opening. A ring member may be rotatably attached to the member; the pair of shaft members may be attached to the plate-shaped attachment member at predetermined intervals.

It may be attached to a rod-shaped body having a grip portion, and the rod-shaped body may be a rod-shaped body whose length can be adjusted (or can be extended or expanded).

The present invention also includes a set (or walking or movement assisting device) of the runner and a rail having a hollow tubular cross section having a running wall on which the runner can run along the slit-shaped opening. In this set, the rail comprises a plurality of running walls extending inward from opposite side walls at different height positions.

In such a set of the runner and the rail, the rotating member (or rolling member) of the runner comes into contact with the running wall and can rotate (or roll) as the runner runs, and each rotating member can rotate. Can rotate in opposite directions to prevent the runner from running excessively. Further, the runner's rotating member (or rolling member) can be supported and rotated (or rolled) at a plurality of positions different in the height direction. Therefore, even if a load is applied, the runner can run stably and smoothly while being supported at a plurality of positions having different heights.

The upper surface (running surface) of the running wall may be inclined downward toward inward to form an inclined surface. A plurality of, for example, a pair of traveling walls may extend inward facing each other from the opposite inner wall portions of the rail at different height positions.

In the rail, for example, the running wall and the protruding wall (or the regulating wall) may be extended inward from the inner wall portion so as to face each other, and the running wall and the protruding wall (or the regulating wall) may be formed on the lower wall. In the form, it may extend inward from both side walls on the slit-shaped opening side. Even in such an embodiment, in order to bring the rotating member (or rolling member) into contact with the traveling surface of the traveling wall, the height position of the upper surface (for example, the inclined surface) of the traveling wall is set to the protruding wall (or the regulating wall). It may be formed higher than the upper surface (which may be inclined downward toward the extending direction). Further, on the upper surface of the protruding wall (or the regulating wall), the rotating member may run in a non-contact state, and the protruding wall (or the regulating wall) may regulate the excessive inclination of the runner. Such a running wall and a protruding wall (or a regulating wall) may be formed as a pair of lower walls which may form a slit-shaped opening.

The present invention will be described in detail below with reference to the accompanying drawings. Hereinafter, the same members or elements (or members or elements having the same functions) will be described with the same reference numerals.

In the example shown in FIGS. 1 to 6, the rail 1 has a quadrangular (or square frame) cross section in which the central portion in the width direction of the lower wall is opened to form a slit-shaped opening. On both side walls (inner wall portions) 3 and 4 facing each other, a first running wall 5 as a lower wall forming a slit-shaped opening extends inward from one inner wall portion 3, and the other inner wall portion 4 From the above, the second running wall 6 extends inward at a different height position from the first running wall 5, and the upper surfaces of these running walls 5 and 6 are inward, respectively. It is formed as inclined surfaces 5a and 6a inclined downward toward (extending direction). These inclined surfaces 5a and 6a form a traveling surface or a traveling path on which the rotating members of the runner 21 come into contact with each other to travel. That is, from the opposite side walls (inner wall portions) 3 and 4, a pair of running walls 5 and 6 having inclined surfaces (running surfaces or running paths) 5a and 6a at different height positions are opposed to each other. It extends to the direction.

More specifically, the rail 1 extends inward from the upper wall 2, the side walls 3 and 4 extending from both sides of the upper wall, and the lower portions of the opposite side walls, respectively, and the tips are slit apart from each other. It is provided with lower walls 5 and 7 that form a shaped opening. The upper surfaces of both lower walls 5 and 7 are formed as inclined surfaces 5a and 7a inclined inward (extending direction), respectively, and the height position of the inclined surface 5a of one lower wall 5 is It is formed higher than the inclined surface 7a of the other lower wall 7. Therefore, the one lower wall 5 can be formed as a first running wall 5 that can come into contact with the rotating member of the runner 21, and the other lower wall 7 can run the runner 21 in a non-contact state with the rotating member. When the runner 21 is excessively tilted, it can be formed as a protruding wall (or a regulating wall) 7 that comes into contact with the runner 21 (for example, a shaft member of the runner 21) and regulates the excessive tilt of the runner 21.

The second running wall 6 has an inner wall 4 facing the inner wall 3 on which the first running wall 5 is formed, and has a different height position from the first running wall 5. , It is formed on the inner wall portion 4 above the first running wall 5. That is, the first running wall 5 and the second running wall 6 are formed on the opposing inner walls 3 and 4 so as to extend alternately from different positions in the height direction.

Further, the rotating member of the runner 21 is excessively displaced (running deviation) from the traveling path (inclined surface) at the corners of the first traveling wall 5 and the second traveling wall 6 and the inner wall portions 3 and 4. ), The regulation wall portions (regulation step portions) 8 and 9 are formed so as to project inward.

Although the rail 1 has a predetermined length in order to improve transportation efficiency, it can be connected to each other and extended. That is, the four corners of the rail 1 of this example (the inner walls of the corners of the upper wall 2 and the side walls 3 and 4, and the corners of the side walls 3 and 4 and the first running wall 5 and the protruding wall 7). The outer wall) is formed with connecting grooves 10a, 10b, 11a, 11b having an arc-shaped cross section (or a C-shaped cross section) having a narrow opening for connecting with a connecting pin (not shown).

Further, on the outer wall of the corner portion between the upper wall 2 and the side walls 3 and 4, there are mounting grooves 13a and 13b having a U-shaped cross section that can be fitted or mounted on the bracket for mounting the rail 1 at a predetermined portion. It is formed.

On the other hand, the runner 21 includes a pair of traveling units 22 (first traveling unit 22a and a second traveling unit 22b) capable of traveling along the slit-shaped opening of the rail 1, and a shaft member of the pair of traveling units. 23a and 23b include narrow plate-shaped mounting members 28 that are mounted at predetermined intervals in the traveling direction of the runner 21. The shaft members 23a and 23b of the traveling units 22a and 22b have a circular cross-sectional shape that can be slidably arranged in the slit-shaped opening, and the shaft members have an axial direction (vertical direction in the illustrated example). A pair of balls that come into contact with the traveling path (contact surface) of the rail 1 and are independently rotatable in the circumferential direction (lateral direction or horizontal direction in the illustrated example) of the shaft members 23a and 23b at predetermined intervals. Bearings (first ball bearings 24a, 24b and second ball bearings 25a, 25b) are mounted or mounted. The outer rings of the ball bearings 24a, 24b, 25a, and 25b are coated with resin to reduce running noise. In such a traveling unit 22a, 22b, the bottom walls of the ball bearings 24a, 24b, 25a, 25b come into contact with the inclined surfaces of the traveling walls 5, 6 and rotate in the circumferential direction of the shaft members 23a, 23b. However, it can travel along the rail 1.

In order to suppress damage to the shaft members 23a and 23b between the mounting member 28 and the first ball bearings 24a and 24b due to contact with the first traveling wall 5 and the protruding wall 7, and to improve the sound deadening property. The pair of bale bearings 24a, which are made of plastic such as vinyl chloride resin and are equipped with the first ring-shaped rotating members (collars) 26a and 26b that can rotate in the circumferential direction of the shaft members 23a and 23b. The shaft members 23a and 23b between 24b, 25a and 25b have a second ring-shaped rotation that can rotate in the circumferential direction of the shaft members 23a and 23b in order to suppress damage due to contact with the second traveling wall. Members (colors) 27a and 27b are attached. In this example, the second rotating members 27a and 27b are made of a metal such as stainless steel.

Further, in this example, screw portions (not shown) are formed at the lower ends of the shaft members 23a and 23b, and the mounting members 28 are spaced apart from each other in the longitudinal direction to form the shaft members 23a and 23b. A screw hole (not shown) into which the screw portion of the screw can be screwed is formed. Therefore, by screwing the screw portions of the shaft members 23a and 23b into the screw holes of the mounting member 28 and screwing the nut 29 into the screw portion protruding from the mounting member 28, the pair of traveling units 22a are screwed into the mounting member 28. , 22b can be fixed.

As shown in FIGS. 1 and 5, a connection unit 41 for connecting to the string-like body 42 can be attached to the attachment member 28. In this example, the box-shaped connection unit 41 is provided with a tension control mechanism capable of adjusting the tension of the string-shaped body 42 connected to the user's body restraint, and the user's movement acceleration is caused by a fall or the like. When the size becomes large, the string-like body 42 is pulled to prevent the user from tipping over. In this example, the mounting holes formed in the mounting member 28 (in this example, four mounting holes formed on both sides) and the mounting holes that can be inserted or mounted in these mounting holes are formed in the connection unit 41. A screw member 43 that can be screwed into the screw hole and a screw member 43 that is inserted or mounted in the mounting hole and screwed into the screw hole of the connection unit 41, the lower wall of the mounting member 28 and the upper part of the connecting unit. The mounting member 28 and the connecting unit 41 are connected or connected by using nuts 44 that can be screwed on the wall.

Further, as shown in FIG. 1, the user (elderly person, physically handicapped person, etc.) is wearing a physical restraint device (jumper with a hanging string, etc.) 45, and the physical restraint device and the runner 21 are connected to each other as a connection unit. It is connected via 41, and the movement (running) of the runner 21 assists (supports) the walking (movement) of the user (elderly person, physically handicapped person).

When such a runner 21 travels along the slit-shaped opening of the rail 1, the ball bearings 24a, 24b, 25a, and 25b of the traveling units 22a and 22b independently run on the first traveling wall 5 and the first traveling wall 5. It comes into contact with (and is supported by) the inclined surfaces (running surfaces) 5a and 6a of the traveling wall 6 of 2 and rotates while sliding. That is, in each of the traveling units 22a and 22b, the first and second ball bearings 24a, 24b, 25a and 25b have the inclined surfaces 5a of the first traveling wall 5 and the second traveling wall 6 having different height positions. It slides in contact with 6a and travels while rotating in the opposite direction. Therefore, the runner 21 does not excessively slide and run (slide), and can run stably and smoothly even when a predetermined load is applied.

Further, even if the preceding traveling unit 22a tries to move in a direction deviating from the predetermined traveling path (in the wrong direction) at the branching portion of the traveling path, the following traveling unit 22b corrects the traveling direction of the preceding traveling unit 22a. to correct. Therefore, the runner 21 can change the direction while traveling smoothly and stably in conjunction with the movement or walking of the user even on the branched traveling road. Therefore, the runner 21 (or the traveling units 22a and 22b) and the rail 1 can be effectively applied not only to a straight or curved traveling path but also to a curved traveling path, a branched traveling path, and the like.

FIG. 6 is a schematic perspective view of a partial notch showing an example of the run path of the rail and the runner.

In this example, the runways of the runners 21 are arranged so as to face each other at a predetermined distance, and a pair of opposing rails 1a having a runway (running groove, in this example, a straight runway) on which the runner 21 can run. It is arranged at the intersection of 1b and the orthogonal rail 1c which is orthogonal to the axial direction of each of the opposing rails and has a running path (running groove, in this example, a straight running path) on which the runner 21 can run, and each of the rails 1a to 1c. The runner 21 is formed of a traveling path forming member 51 for forming a branch traveling path 61 capable of guiding the runner 21 on the traveling paths of the rails 1a to 1c, and the runner 21 is a straight traveling path of the rails 1a to 1c. It is possible to travel along the branch traveling path 61 formed by the traveling path forming member 51.

In this example, the traveling path forming member 51 is arranged in the central region of the intersection, and has a central guide plate (central guide member) 52 having a substantially isosceles right triangle shape and a peripheral portion of the central guide plate. The first to third peripheral guide plates (peripheral guide members) 53 to 55 arranged at intervals are provided, and the corner portions (first to third corner portions) 52a of the central guide plate 52 are provided. ~ 52c are chamfered and curved. Of the central guide plate 52, the radii of curvature of the first and second corner portions 52a and 52b located at the branch portions on the opposite rail 1a and 1b sides may be formed to be about 8 to 12R, and may be formed on the orthogonal rail 1c side. The radius of curvature of the third corner portion 52c located at the branch portion is set to be larger than the radius of curvature of the first and second corner portions 52a and 52b, and may be formed to be about 10 to 15R.

The first peripheral guide plate 53 and the second peripheral guide plate 54 have a substantially pentagonal shape in which one of the corners of a substantially quadrangle is cut out to form a hypotenuse, and the hypotenuse is formed. , Facing the hypotenuse of the central guide plate 52 and arranged symmetrically with respect to the axis of the orthogonal rail 1c. The third peripheral guide plate 55 has a substantially rectangular shape, and is arranged along the axial direction of the opposing rails 1a and 1b.

Of the first and second peripheral guide plates 53, 54, a pair of corner portions located on both sides of the hypotenuse portion (on the fourth corner portions 53a, 54a and the orthogonal rail 1c side located on the opposite rails 1a, 1b side). The located fifth corner portions 53b, 54b) are chamfered and curved. The radius of curvature of the fourth corner portions 53a, 54a of the first and second peripheral guide plates 53, 54 may be formed to be about 10 to 15R, and the first and second peripheral guide plates 53, 54 may be formed. The radius of curvature of the fifth corner portions 53b, 54b is set smaller than the radius of curvature of the fourth corner portions 53a, 54a, and may be formed to be about 8 to 12R.

By arranging the central guide plate 52 and the first to third peripheral guide plates 53 to 55, a branch travel path 61 is formed, and the branch travel path corresponds to the outer peripheral portion of the central guide plate 52. Each rail 1a to 1c is formed between a loop-shaped traveling path 62 having a substantially isosceles right triangular shape and peripheral guide plates 53 to 55 adjacent to each other, and leads to a corner portion of the loop-shaped traveling path 62. Includes three linear connecting paths 63a to 63c extending in the axial direction of the above. The loop-shaped traveling path 62 is branched and inclined through the traveling path of the orthogonal rail 1c and the linear straight path 62a leading to the traveling paths of the opposing rails 1a and 1b, and the straight road 62a (this straight path 62a). In the example, it is formed by a pair of ramps 62b and 62c leading to the end of a straight road), and the pair of ramps 62b and 62c are about 30 to 40 ° with respect to the axial direction of the orthogonal rail 1c. It is tilted at the tilt angle.

In this example, the central guide plate 52 and the first to third peripheral guide plates 53 to 55 are made of metal (for example, stainless steel).

A plate-shaped base 71 made of metal (for example, stainless steel) is fixed to the ceiling wall, and each of the plate-shaped bases is provided with a long nut 73 and a screw member 74 at regular intervals. Guide plates 52 to 55 are attached. A plurality of mounting holes 72 are formed in the guide plates 52 to 55, and the long nuts 73 are provided so that the mounting holes 72 and the mounting holes of the plate-shaped base 71 corresponding to the mounting holes maintain a predetermined interval. And is fixed by the screw member 74. Further, in order to shield the internal space formed by the traveling path forming member 51 and the plate-shaped base 71 from the outside around (periphery) the traveling path forming member 51, the first to third peripheral guiding plates 53 The peripheral guide plates 53 to 55 are provided by the long nut 73 and the screw member 74 in a form in which the U-shaped side plate 75 formed of metal (for example, aluminum) is interposed between the base 71 and the base 71. And the side plate 75 and the plate-shaped base 71 are fixed.

Further, in order to align (position) the upper surface of each peripheral guide plate 53 to 55 with the height position and the position in the width direction of each rail 1a to 1c, the first to third peripheral guide plates 53 to 55 are each rail. A pair of slits (or grooves) 76 extending in the connection direction with the connection portion corresponding to the connection grooves 10a, 10b, 11a, 11b of 1a to 1c, and a tip fixed (fixed by welding or the like) to the slits. It is provided with a positioning pin (connecting pin, support rod) 77 having a protruding portion. The central guide plate 52 and the first to third peripheral guide plates 53 to 55 not only form a branch travel path 61 leading to the travel paths of the rails 1a to 1c, but also form a lower wall with respect to the plate-shaped base 71. The lower wall is formed and provides a running surface on which the runner 21 can run.

The length of the branch road 61 formed by the road forming member 51 may be relatively short because it is used for changing the direction of the runner 21. Therefore, the first ball bearings 24a and 24b of the runner 21 can move smoothly while sliding against the lower wall (running wall) of the runway forming member 51.

In this example, the traveling path forming member 51 forms the connecting traveling paths 63a to 63c in the axial direction of the rails 1a to 1c, and forms the loop-shaped traveling path 62. The central guide plate 52 and the first and second periphery. Each corner of the guide plates 53 and 54 is curved, and the runners 21 arranged in the runways (running grooves) of the rails 1a to 1c are smoothly moved (guided) along the branch runway 61. ), And the runner 21 can smoothly change the direction along the curved surface and guide the runners to the traveling paths of the rails 1a to 1c.

A connecting runway is not always necessary, and a loop-shaped runway (a runway having a closed form and leading to the rail runway) leading to the rail runway may be formed, but usually, the runway forming member is used. , It may be possible to form a connecting running path leading to the running path of each rail and the loop-shaped running path (for example, the corner portion of the loop-shaped running path). Further, in the above example, each peripheral guide plate forms a loop-shaped traveling path and a connecting traveling path, but the traveling path forming member forms a connecting traveling path with a peripheral guiding member forming the loop-shaped traveling path. It may be provided with an intermediate guide member or a peripheral guide member to be formed.

The runway forming member forms a lower wall (running wall) on which the first ball bearing of the runner can slide or slide, but the running path forming member has the same height as each of the rails. Running walls (protruding walls if necessary) may be formed at different positions.

Further, in the above example, although one branch traveling path formed by the traveling path forming member is illustrated, a plurality of branch traveling paths can be formed. For example, a main rail composed of a plurality of rail members (for example, a plurality of opposing rail members) corresponding to each passage such as a facility, and a predetermined place (for example, a bedroom, a bathroom, a toilet, etc.) from the main rail. A plurality of branch runways are formed by a subrail (for example, one orthogonal rail member) extending to a toilet, a kitchen, an entrance, etc., and a runway forming member arranged at each intersection of the main rail and the subrail.
