Description

[Detailed description of the invention] [Industrial field of application] There is a well-known elevator that is equipped with a roller that engages with the guide rail and a sprocket that engages with the pin rack so as to be able to move up and down a wall surface on which a guide rail and a pin rack are vertically fixed. It is.

The present invention relates to an improvement of the guide rail, and is designed to facilitate the attachment and detachment of the elevator to the guide rail at the site of use.

[Conventional technology]

The elevator is equipped with a sprocket in the center, and rollers at the ends of protruding rods that protrude from both sides in the shape of crab scissors. The elevator that has been brought to the front of the wall cannot be advanced to the mounting position because the length between the left and right rollers is greater than the length between the left and right guide rails. The roller must be removed, placed in the mounting position, and then reinstalled. The same applies to removal. However, since the elevator is a heavy object, this removal and reinstallation is by no means an easy task.

[Problem that the invention attempts to solve]

In the present invention, a predetermined height section of the guide rail is omitted so that the elevator can be carried into a predetermined mounting position with the roller support member attached. To do this, the missing part must be able to be closed so that it does not interfere with the elevator's ascent and descent. In addition, if necessary, consideration must be given to the strength of the missing part so that it can withstand vertical loads.

〔Example〕

The drawings will be explained. Two guide rails G with a groove-shaped cross section and a pin rack P in the center are both fixed to the wall surface in several positions. On the other hand, elevator C
has a pair of upper and lower protruding rods Ku, Kl on both sides, and a roller R attached to the end of the upper protruding rod Ku engages with a groove in the guide rail G. The elevator also includes a rotatable sprocket S, which engages with a pin of a pin rack P to allow the elevator to move up and down.

The guide rail G is missing a predetermined height section, and the movable rail 1 is inserted and complemented in this period and connected to the upper and lower fixed rails 2 and 3 to form the guide rail G. Rails 1 and 2 and rails 2 and 3 are both hinges 4
The rail 1 is rotatable with respect to the rails 2 and 3. An arm 5 having a groove-shaped cross section and a predetermined length is fixed to and protrudes from the back surface of the movable rail 1. The above arms are provided symmetrically on the left and right guide rails, and the opposing arms can be positioned in a straight line.
The engagement beam 6 has a groove-shaped cross section, and one end thereof is rotatably pivoted to one arm, and when both arms are in a straight line, it can be placed over the other arm to integrate the two.

The present invention is constructed as described above. The elevator brought to the site will be placed in front of the wall. In FIG. 4, the distance between the left and right rollers of the elevator is assumed to be L1. When both arms 5 are pushed, the movable rail 1 rotates, and the distance between the ends of the groove-shaped legs on the entrance side becomes small to L2. L2 is L
If it is designed to be smaller than 1, the elevator can be moved forward and each roller can be inserted between the grooves of the movable rail. When both arms are returned to a straight line and the engagement girder 6 is engaged, the movable rail is continuous and integrated with the fixed rail. At this time, the sprocket S and the pin rack P are also in the engaged position, so that it can be moved up and down.

Both fixed rails 2 and 3 have their side surfaces fixed to the wall via support members (not shown).
If reinforcement against vertical stress is required, a reinforcing plate 7 is used. The reinforcing plate 7 has a rectangular shape, and the fourth
As shown in the figure, the upper and lower ends are fixed to the lower end of the fixed rail 2 and the upper end of the fixed rail 3, respectively, at positions that do not impede the rotation of the movable rail. Although the elevator is provided with the upper and lower protruding rods Ku and Kl as described above, only the upper roller R engages with the guide rail groove as shown in FIG. The lower roller can be rolled by rolling on the outside of the guide rail. However, even in that case, the fifth
As shown in FIG. 6, a protrusion 8 is provided on the lower protruding rod Kl, and this is engaged with a groove in the guide rail. In this case, a rotating rail is also provided at a location corresponding to the lower protruding rod.

FIG. 7 shows another embodiment, in which the tips of both arms are joined by a hinge 9. As a result, when one arm is moved, both arms rotate symmetrically. In this case, the arm is not fixed to the movable rail 1 and the hinge 10
The above operation will be smoother if the two are connected. In either case, it is necessary to incline the end face of the arm accordingly.

〔effect〕

Conventionally, two workers were required to assemble the elevator into the guide rail, and even then, the work was not easy. This invention can be easily installed by one person. The same goes for the cleanup work.
