FIG. 1 is a perspective view showing the whole wheelchair mounted climbing device according to the present invention, in which rollers are built in roller guides 1, 1 ′ installed on both sides of the staircase S. FIG. As with the stairs S, the wheelchair mounting device 4 extends horizontally along the oblique roller guides 1 and 1 'from the lower slope of the carrier integrated with the left and right climbing frames 3 and 3' connected to the rollers. Yes. With the wheelchair in the state shown by the broken line on the mounting device 4, the winch 5 is driven and the carrier is pulled up by the wire, thereby the floor guides 1 and 1 ′ on the left and right of the stairs S along the floor. You can climb up. When descending, the wire winder, that is, the wire of the winch 5 is fed out to descend by the weight of the carrier. A safety stopper 6 for preventing the wheelchair from falling off is provided near the front end of the mounting device 4. W is a large wheelchair roller, and ω is a small roller (front wheel).

2 is a side view of the wheelchair-mounted climbing device of FIG. 1, and FIG. 3 is a plan view. The cross-sectional shape of the left and right roller guides 1, 1 ′ of the staircase S is a shape in which only the center of the upper side of the square pipe is cut out and the slit 7 is opened, and a commercially available hanger rail can be used upside down as a building part. A roller unit consisting of front and rear rollers R1 and R2 is inserted into the square pipe from the end, and the mounting shaft 8 protrudes upward from the slit 7 and is connected to the climbing frames 3 and 3 by nuts b1 and b2 in FIG. ing. The lower ends of the left and right climbing frames 3 and 3 ′ are connected by a connecting plate 9 in an inclined state, and the groove plates 10 and 10 ′ for mounting a wheelchair are fixed to both ends of the connecting plate 9 in a horizontal state. The mounting device 4 is configured by connecting the tip ends with the connecting plate 11, and the wheelchair is put into the groove plates 10 and 10 '.

Details of the mounting device 4 are shown in a side view of FIG. 4 and a plan view of FIG. As shown in FIG. 5, bolt holes 2, 2 ′ into which the roller mounting shafts 8, 8 ′ are inserted are opened at two upper and lower positions of the left and right climbing frames 3, 3 ′. After all, the roller unit mounting shafts 8 and 8 'are inserted into the front and rear, right and left four places in total, so as shown in FIG. 4, the front and rear right and left four places are equipped with roller units composed of the rollers R1 and R2. .
And the upper part of climbing frame 3 and 3 'and the outer surface of the front-end | tip of right and left groove plate 10 and 10' are connected with the balustrade-like reinforcement bar 12 and 12 'of the front-back direction, and it is zigzag-shaped between them. The auxiliary bars are welded to form a truss structure. Both ends of a safety stopper 6 formed by forming a reinforcing bar in an inverted U shape are inserted and attached to the lateral holes of the distal outer walls of the left and right groove plates 10 and 10 '. When the horizontal pin inserted into the holding cylinder 13, 13 ′ fixed to the front end of the reinforcing bar 12, 12 ′ is inserted into the horizontal hole provided in the safety stopper 6, the safety stopper 6 is raised as shown by the solid line When the horizontal pin is pulled out, it is in a state of being tilted forward as shown by the chain line. In this manner, after pushing the safety stopper 6 down, the wheelchair is pushed onto the left and right groove plates 10 and 10 'from the front, and then the safety stopper 6 is raised, and the lateral pins in the holding cylinders 13 and 13' are moved to the safety stopper. 6 to prevent the wheelchair from falling off.

Horizontal pulleys P1 and P2 are attached to the positions of the left and right groove plates 10 and 10 'near the climbing frames 3 and 3' with a vertical axis, and the wire W fed from the winch 5 passes through the horizontal pulleys P1 and P2. Then, after making a U-turn with the vertical pulley P3 attached and fixed to the upper end of the right roller guide 1 ′, it is attached and fixed to the brake lever 14 of FIG. A roller mounting shaft 8b fixed to the center of the roller holder 15 that pivotally supports the brake lever 14 at the front end (upper end of the hill) protrudes upward from the slit 7 of the roller guide 1 ′, and is further extended to the climbing frame 3 ′. The bolts b1 and b2 are tightened and fixed in a state of passing through the bolt holes 2b. In the roller guide 1 ′, the tension coil spring 16 is mounted between the roller mounting shaft 8 b and the brake lever 14, so that the pulling force by the wire W is as follows: wire W → brake lever 14 → tension coil spring 16 → mounting shaft 8 b → Ascending / descending frames 3 ′ → mounting device 4 are operated in this order, and the left and right side pulleys P1 and P2 near the descending frames 3 and 3 ′ of the ascending / descending frames 3 and 3 ′ are connected by wires W from above the hill. By pulling, the climbing frames 3, 3 ′ and the mounting device 4 are pulled up together.

Finally, as shown by the chain line in FIG. 2, the mounter 4 climbs up to the top of the roller guides 1 and 1 'so that the groove plates 10 and 10' are at the same height as the deck d such as a ship. Then, the hoisting operation by the winch 5 is stopped, and the wheelchair moves from the groove plates 10 and 10 'onto the deck d and escapes. Alternatively, when the roller guides 1 and 1 ′ are fixed to a building or the like, the roller guides 1 and 1 ′ move to the same level as the uppermost staircase S or the floor surface d one step above and escape.

In this way, when the mounting device 4 is pulled up with the wire W, if the wire W is broken, it is connected to the lower end of the brake lever 14 by the tension coil spring 16 with the mounting shaft 17 of the brake lever 14 as a fulcrum. The metal brake plate 18 is pulled in the wire W direction, that is, in the upward direction of the slope of the roller guide 1 ′. As a result, since the rubber plate 19 with a sharp slope on the lower surface of the metal brake plate 18 bites in a wedge shape between the rollers R1 and R2 and the square pipe bottom plate 1b together with the metal plate m on the metal brake plate 18, it serves as an emergency brake. Works. In addition, since the brake lever 14 protrudes upward from the slit 7 of the square pipe top plate, manual operation can also be performed from the wheelchair mounting device 4 side.

2 and 3 show an example in which the wheelchair-mounted climbing device of the present invention is climbed to a deck such as a pleasure boat or a leisure boat. A pair of upper and lower horizontal shafts a1, a1 ', a2, a2' are fixed outwardly in a direction perpendicular to the roller guides 1, 1 '.
An L-shaped receiving groove 20 is provided at a position corresponding to the horizontal axes a1, a1 ′, a2, a2 ′ on the uppermost floor of a staircase in a house or the like, or a deck d such as a pleasure boat or boat. The receiving hooks f1 · f1 ′ and f2 · f2 ′ are fixed.

Now, if the horizontal axis a2, a2 ′ on the hill side is inserted into the L-shaped receiving groove 20 of the receiving hooks f2, f2 ′ on the near side on the deck d of the anchored boat, even if the boat shakes, Using the horizontal axes a2 and a2 ′ as fulcrums, the wheelchair mounted climbing device also moves up and down or swings. At this time, when the mounting device 4 of the wheelchair mounted climbing device is lowered onto the sandy beach, the healthy person can climb up and down from the sandy beach using the stairs S, and there is no obstacle. The wheelchair climbs up to the top of the roller guides 1 and 1 'by winding the wire W with the winch 5 as described above in a state where the wheelchair is placed on the groove plates 10 and 10' of the wheelchair mounting device 4. You can transfer to the deck d or to the upper floor. Note that the mounting device 4 may be a floor plate that is entirely flat, omitting the groove plates 10 and 10 '.

If it becomes unnecessary after getting on and off the boat, the wheelchair mounted climbing device may be lowered to the land side such as sandy beach, but the entire wheelchair mounted climbing device is mounted on the boat deck d You can also That is, when the hill side of the roller guides 1 and 1 ′ is lifted, the horizontal axes a1 and a1 ′ at the uppermost end are inserted into the L-shaped receiving grooves 20 and 20 ′ of the receiving hooks f1 and f1 ′ on the deck d. And locked.

The outer diameter of the fan-shaped rocking plate 23 is large enough to block the upper end entrance of the L-shaped groove 20, so when the loader 4 side is lifted until the roller guides 1, 1 ′ are horizontal, When the horizontal shafts a1 and a1 ′ push the fan-shaped rocking plate 23 away and fit into the L-shaped groove 20 and the L-shaped horizontal portion is fully inserted, the locking is completed, and then the fan-shaped rocking plate 23 has its own weight. Then, the balance returns to the balance position shown in FIG.
In this way, the ship or the like can run with the roller guides 1 and 1 'mounted horizontally, but the safety pin 24 is provided so that the lock by the fan-shaped swing plate 23 is not released. The safety pin 24 inserted and held in the cylinder 25 fixed on the side surface of the fan-shaped swing plate 23 protrudes into the L-shaped grooves 20 and 20 ′ and comes into contact with the inner surface of the hook vertical portion 21 to serve as a stopper. Further, the risk that the fan-shaped rocking plate 23 rotates further and the upper end inlets of the L-shaped grooves 20, 20 ′ are inadvertently opened and the uppermost horizontal axes a1, a1 ′ are detached is prevented. Note that a bayonet mechanism or the like is also provided to prevent the safety pin 24 from being unintentionally removed.

When the fan-shaped rocking plate 23 is rotated counterclockwise about the horizontal axis 22, the safety pin 24 passes and rises through the upper end inlets of the L-shaped grooves 20 and 20 ', and the receiving hook vertical portion 21 of the receiving hook vertical portion 21 is Since the fan-shaped rocking plate 23 does not block the upper end entrance because it stops in contact with the back surface, the horizontal axes a1 and a1 ′ at the uppermost end are separated from the L-shaped grooves 20 and 20 ′, and the roller guides 1 and 1 are stopped. The tip of 'can be lowered to the ground such as sandy beach. Needless to say, when the roller guides 1 and 1 'of the present invention can be always fixed in an inclined state on both the left and right sides of a building or other existing stairs, the locking means as shown in FIGS.
