Description

[Detailed description of the invention] The present invention is a relocation system that can slide the goods down along the slope of the stairs, for example, when transporting goods from the second floor of a building to the first floor. The present invention relates to a foldable stair slide that is a possible transportation aid.

Conventionally, when moving items, people had to take elevators or carry them up and down stairs when moving.

However, when using an elevator, the ascending and descending speed is slow, and
There is an inconvenience in that the amount of work is limited due to limitations in volume and payload, and in the case of manual cargo handling, there is an inconvenience in that it takes a lot of effort to go up and down the stairs and the work efficiency is poor.

The present invention was made to solve the above-mentioned disadvantages, and is installed so that the length can be adjusted and moved along the slope of a straight staircase other than a spiral staircase, and articles can be slid on the top surface of the staircase. The object of the present invention is to provide a foldable stair sliding board that can be transported.

In order to achieve the above object, the present invention is characterized by a sliding plate consisting of an upper sliding plate, an intermediate sliding plate, and a lower sliding plate, and each sliding plate has a rising part on both sides and crosses the sliding plate. The lower sliding plate is made of wooden plate-like plates with slightly different surface dimensions and is inserted into the underside of the upper sliding plate, so that its total length can be adjusted according to the length of the slope of the stairs, and it can be installed on the slope of the stairs. an upper board disposed on the landing step at the top of the stairs and one end of which is foldably hinged to the upper end of the upper sliding board; and a lower end of the lower sliding board located on the landing step at the bottom of the stairs. and an arc-shaped deceleration plate whose one end is foldably hinged, and further provided below the lower end of the lower sliding plate so that the lower end of the sliding plate can be adjusted according to the inclination angle and riser height of the stairs. The slide plate is provided with a lower leg whose angle and height are adjustable for supporting the slide plate, and a slide plate locking fitting for locking the overlapping portion of the rising portions on both sides of the slide plate.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

Figure 1 is a perspective view to explain the overall configuration, Figure 2 is a plan view and cross-sectional view of the upper sliding plate, Figure 3 is a cross-sectional view showing the overlapping of the sliding plates, and Figure 4 is the lower sliding plate. FIG. 5 is a perspective view showing the connecting portion with the deceleration plate, and FIG. 5 is a view showing the state in which the sliding plate lock fitting is installed.

In the drawings, 1 is an upper riding board, and 2 is a sliding board.

The sliding plate 2 consists of an upper sliding plate A, an intermediate sliding plate B, and a lower sliding plate C, and each of these sliding plates A, B, and C
Each of these has a cross section shaped like a deck plate to increase its strength, and also has raised portions on both sides to prevent the transported items from falling off laterally when they slide down.

In addition, as shown in FIG. 3, a cross-sectional view of the overlapping portion of the intermediate sliding plates A, B, and C, respectively, the intermediate sliding plate B
are made so that the cross-sectional dimensions are slightly different so that they fit under the upper sliding plate A, and the lower sliding plate C fits under the intermediate sliding plate B.

The intermediate sliding plate B functions to adjust the total length of the sliding plate 2 according to the length of the sloped part of the stairs.In particular, in the case of a staircase with a short sloped part, the intermediate sliding plate B and the upper sliding plate A are used. The overall length can also be adjusted by adjusting the overlap length with the lower sliding plate C.

These two sliding plates (upper sliding plate A and intermediate sliding plate B, or intermediate sliding plate B and lower sliding plate C1, or upper sliding plate A and lower sliding plate C when the staircase slope is short) In order to clamp the overlapping parts of the rising parts on both sides and fix the two sliding plates, a total of four sliding plate locking fittings shown in Fig. 5 are used, and as a result,
When the folding stair sliding board of the present invention is installed on the slope of a staircase, it is prevented from moving up and down, front and back (above or below the stairs), and left and right.

Reference numeral 3 denotes a hinge that connects the upper riding plate 1 and the upper sliding plate A in a foldable manner.
is placed on the landing step at the top of the stairs, and the folded part shown as the overlap part 4 in FIG. is provided on the upper riding board 1, and an overramp 4 of and is arranged to overlap on the upper sliding board A when the upper sliding board A is installed on the stairs.

Reference numeral 5 indicates a leg assembly 5, and 6 indicates a lower leg consisting of a height adjustment bolt 7 and a bottom portion 8. The leg assembly 5 is attached to the lower end of the lower sliding plate C as shown in Fig. 4. Then, the lower leg 6 is assembled to this leg assembly metal fitting 5.

The lower leg 6 has a structure in which a height adjustment bolt 7 can freely rotate or tilt at a predetermined angle. By adjusting the height adjustment bolt 7, the sliding plate 2 can be adjusted to any inclination angle. This makes it possible to follow the stairs that the robot has, and to respond to stairs with arbitrary riser heights.

The transported article is gradually accelerated and slides down along the slope of the stairs from the upper sliding plate A through the middle sliding plate B to the lower end of the lower sliding plate C, but remains accelerated until it slides down the lower landing etc. If the product reaches a flat surface, it may damage not only the packaging material protecting the product but also the product inside.

The deceleration plate 9 is installed to deal with this.

The deceleration plate 9 is bent into an arc shape and connected to the lower end of the lower sliding plate C by a hinge 10, and as shown in FIGS. 4 and 1, the deceleration plate 9 gradually accelerates when installed on the stairs. It slows the speed of objects sliding down and serves as a shock absorber, and can be folded in at the hinge 10 and integrated with the lower sliding plate C for easy carrying.

The parts of this foldable stair slide that come into direct contact with the stairs or landing (for example, the bottom part 8 of the lower leg 6),
It is recommended to apply cushioning material in advance to prevent scratches and to prevent the plate from sliding.

In addition, in the above-mentioned embodiment, the case was explained in which goods on the second floor are carried to the first floor using, for example, a staircase leading from the second floor to the first floor. Even in the case of folded stairs, there is a curved blow 2 at this intermediate landing.
By installing a conveyor and installing folding stair sliding boards between the second floor landing and the curved roller conveyor and between the curved roller conveyor and the first floor landing,
It can be used in the same way as in the embodiment.

According to the present invention, when transporting goods from the upper floor to the lower floor, the burden of going up and down stairs is eliminated, and if an elevator is installed, the goods can be transported in parallel with the elevator. This will improve work efficiency.
