Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a simple stair climbing machine that is attached to an ordinary staircase and used for raising and lowering a care recipient in a welfare tool.

[0002]

[Prior art]

 Conventionally, stair lifts that are attached to ordinary stairs and used for elevating care recipients have laid guide rails on one side of the stairs, and chair-type elevators have rails, cables, drive units, seats and various parts. Related to a folding storage mechanism for a seat, a safety device, a steering operation device, and a control device, the device includes an engagement tool and the like.

[0003]

[Problems to be solved by the invention]

 For elevators equipped with chair-shaped seats, if the guide rail is laid on the side of the stairs, the width of the rail is wide and the width of the stairs is small. Each of them requires reinforcement work on the supporting parts of the existing structure, and those that support the chair-shaped seat in a cantilever manner require additional stiffening of the rails and supporting tools. In addition, overhangs on treads or landings may cause obstacles to stair traffic, and a stair climber with a simple structure that can be easily attached to the existing stairs is required while solving such problems.

[0004] The present invention has been made in view of such problems in the prior art, and a purpose thereof is to provide a pair of racks along the slopes on both sides of the stairs, and to attach the axle to the seating bogie. An attempt is made to provide a stair lift having a simple structure in which a supported pinion is meshed with the rack and driven up and down by a motor directly mounted on a speed reducer, and after use, the truck is removed from the rack and stored in an arbitrary place. Is what you do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the stair climber of the present invention has a pair of racks along the slopes on both sides of the stairs, and pinions at both ends of the drive shaft that is mounted between both sides of the body of the seating vehicle. Stops and engages on the same rack.Along the axis of the drive shaft, a motor directly mounted with a speed reducer is interposed to pass through the deceleration output side coaxially and rolling on the same rack as a rail. The wheels are arranged side by side with the pinion and are pivotally supported on both sides of the vehicle body, and a rotating chair is supported above the vehicle body.

[0006] Immediately below the lower surface of the flange formed on the structural member sandwiching both sides of the rack, latches that move in and out of the projecting position and the retracting position are fitted to the lower side of the vehicle body. In the protruding position, the latch is restrained directly below the lower surface of the flange to prevent the seat bogie from being derailed. Conversely, the latch is displaced to the retracted position and the restraint of the latch is released from the lower surface of the flange, and the seat is seated. The truck is to be removed from the rack.

[0007]

[Embodiment of the invention]

 DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings based on an embodiment. Referring to FIGS. 1 to 3, a pair of lightweight racks 1 and 1 are installed along both sides from the bottom of the stairs to the top. Then, the pinions 2 and 2 meshing on the rack are fixed to both ends of a drive shaft 5 which is traversed and supported between the middle sides of the vehicle body 4 of the seating vehicle 3, and a worm gear is provided in the middle of the shaft. A so-called cordless drive type motor 7 having a storage battery pack (not shown) as a power source and a power source connected directly through a shaft of the output side of a speed reducer 6 such as On both sides near the end position of the vehicle, rolling wheels 8, 8 that roll on the same rack as rails are juxtaposed with the pinions 2, 2, and are pivotally supported on both sides of the vehicle body 4. A chair 9 is provided.

[0010] As shown in FIG. 4, the rack 1 has a large number of rack pins 14 between a pair of structural members 10 and 10 having groove-shaped flanges 12 formed laterally. They may be arranged side by side at the mesh pitch interval.

As shown in FIG. 5, the rack 1 has a large number of meshing holes 15 formed between a pair of structural members 10 having groove-shaped flanges 12 formed laterally. A rack plate 16 disposed at a pitch interval may be interposed.

[0010] As shown in FIG. 6, a latch 13 that moves in and out of a protruding position a and a retracting position b is fitted right below the lower surface of the flange 12 on the lower side of the vehicle body. By restraining the latch 13 directly below the flange, derailment of the seat platform is prevented, and conversely, the latch 13 is displaced to the retracted position b to release the restraint of the latch 13 from the lower surface of the flange, and the seat platform is lifted. It is to be removed from the rack.

Further, the cordless drive type motor 7 may be operated by being connected to a power supply connection port of an indoor wiring circuit near the stairs via a hanging wiring cord (not shown).

As shown in FIGS. 1 and 6, the pinion 2 is engaged with the rack at the end position of the rack 1 on the lower or upper floor, as shown in FIGS. The latch 13 is set at the projecting position a on the lower side of the vehicle body 4 and restrained immediately below the flange, thereby preventing derailment of the seat on the rack, and driving the pinion 2 by the motor 7 to seat on the lower floor. The rider moves up and down between the position M1 and the upper sitting position M2, and the occupant at the sitting position M in the middle of the stairs sits downstairs, but stops at the upper sitting position M2, Turn the swivel chair in the direction of the landing where the occupant can easily get on and off.

Next, at the end of the rack, at both ends of the rack, the latch 13 set to the protruding position a is displaced to the retracted position b along the position immediately below the flange 12 to release the restraint with the lower surface of the flange 12, and Remove the seat trolley from above and store it in any location.

[0014]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

In the stair climber according to claim 1, the pair of racks laid on both sides of the stairs along the slope of the stairs extending from the vicinity of the lowest step to the highest landing has a small area occupying both sides of the step. It is a simple, inexpensive and lightweight structure that does not hinder the lifting and lowering, and is easy to lay and can be easily attached to existing stairs. .

[0016] Then, a cordless drive motor is mounted on the seat trolley, cordless driving and operation with commercial power are performed, and a pinion meshing with the rack is driven to move the seat trolley between the lower and upper stairs. It can be operated up and down between the rooms.

Further, the seating trolley is provided with a swivel chair, and the occupant sits downstairs during the ascent / descent operation, stops at the highest position, and places the swivel chair with the occupant on a landing. The seat can be turned easily to get on and off.

In the stair climbing machine according to the second aspect, the latch fitted to the side of the vehicle body is set in a protruding position toward the lower side of the vehicle body and restrained immediately below the flange of the rack during operation of the seat trolley. Derailment of the upper seat trolley can be prevented.

After using the seat trolley, the latch is displaced from the projecting position immediately below the rack flange to the retracted position to release the restraint of the vehicle body from the lower surface of the flange, and the seat trolley is removed from the rack and transferred to an arbitrary storage location. can do.
