Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stair lifting device, and more particularly to the structure of a bracket that supports a rail.

[Prior Art] A conventional device of this type will be explained based on FIGS. 6 to 11. In the figures, (1) is a staircase, and (2) is a staircase (
Brackets consisting of hollow prisms erected at a predetermined interval on the - side of 1), (3), (3) are three C-shaped channels connected in series, and are arranged in two stages above and below along the staircase (1). A pair of rails are attached to the bracket (2) in parallel, and (4) is a car that is engaged by inserting a roller (5) into the rails (3) and (3), and is pulled by a drive mechanism (not shown). The rollers (5) are configured to move up and down the stairs (1) by shifting the rails (3) (see FIG. 11), so that each bracket (2)
As shown in the θ diagram, it is erected on the staircase (1) by an anchor bolt (7) and a nut (8) via a plate (8) at its base end.

By the way, multiple brackets (2) are erected like this.
supports the rail (3) formed by connecting three C-shaped channels in series, and the moment due to the dead weight of the car (4) and the passenger etc. (tJt) acting through this rail (2) (WXL) Requires load characteristics with strength and rigidity that can withstand (WXL).

[Problems to be Solved by the Invention] As described above, the bracket (2) is required to have high strength and rigidity, and the bracket (2) is also required to have a function to adjust the height of the rail. , rail (3) 1
Although it is desirable to support two or more brackets (2), it has not been possible to increase the number of brackets (2) from the viewpoint of appearance. Therefore, each bracket (2
) There is a method to improve the strength and rigidity of the product, but this method increases the weight and significantly reduces installation workability.

Therefore, the present invention analyzes the degree of load imposed by the car (4) etc. on the rail (3), and in particular, analyzes the degree of load applied by the car (4) etc. to the rail (3), and in particular, calculates the load based on the acceleration other than the above-mentioned load during acceleration and deceleration when starting and stopping the car (4). This was done with a focus on the generation of force. In other words, since the car (4) moves up and down at a constant speed at the center of the rail (3), only the load of the car (4) etc. acts on it, but at the top and bottom ends of the rail (3), the above load acts on the car (4). In consideration of the fact that the force associated with the acceleration during acceleration/deceleration is applied and a larger load acts than the central part, we decided to
) is made to have higher strength and rigidity than the other brackets (2).

For example, the load of the car (4) and passengers, etc. is 300Kg.
The force that acts when accelerating and decelerating the car (4) is 300Kg.
X O, 2g = 80Kg (however, 0.2g is acceleration), and in the center there are 2 to 3 brackets (2), and at the ends there are 1 to 2 bladders (2) to connect the basket (0. If supported, the load per bracket (2) at the center is 100 to 150 kg, while at the ends it is 180 to 380 kg.

[Means for Solving the Problems] According to the present invention, among the plurality of brackets installed on the stairs to support the rails, one bracket is attached to each of the upper and lower ends of the stairs than the other brackets in the central part. The stair lift device is constructed by erecting brackets with increased strength and rigidity.

[Function] According to the present invention, it is not necessary to uniformly reinforce all the brackets of the one-stair lifting device, and by simply reinforcing only the brackets located at the upper and lower ends of the stairs, the bracket can be made superior in terms of strength.

[Embodiment] Hereinafter, based on the embodiment shown in FIGS. 1 to 5, the same or equivalent parts as in the conventional art are given the same reference numerals, and the features of the present invention will be mainly explained. , Figure 2 shows the stairs (
1) A side view and a plan view of the bracket (2) installed on the upper floor, where (9) is a reinforcing bracket that is installed along the outer surface of the bracket (2) and reinforces the bracket (2). Such a reinforcing bracket (9) has a cross section formed in the shape of an opening, and the dimensions of each opposing side of the opening gradually increase from the upper end to the lower end (see Fig. 3). is also attached to the bracket (2) on the lower floor, and the other brackets (2) are configured as before (see Figures 4 and 5).

As described above, according to this embodiment, by simply attaching the reinforcing brackets (8) to only the brackets (2) at the upper and lower ends, there is no need to increase the number of brackets, and the rail (3)
In addition to being able to improve the overall strength and W4 properties, it has better footing than the central part, has less impact on installation work and is economical, and there is no need to increase the number of brackets (2).

Adjusting the position of the rail (3) is also easy.

[Effect of the Invention J] According to the present invention, it is possible to reduce the weight of the bracket and improve the strength characteristics without increasing the number of brackets.

It is easy to adjust the position of the rail.
