Description

[Detailed explanation of the idea] This idea concerns improvements to elevator doors.

Generally, the surface of the door that opens and closes the elevator entrance is painted with lacquer or the like, and the tip of the door can be hit by obstacles such as passengers when the door is closed.

In order to prevent the coating from partially peeling off, joints made of aluminum or stainless steel are fixed with screws.

A conventional elevator door will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is an elevator entrance, 2 is a three-sided frame that forms the sides and upper part of the entrance 1, and 3 is a sill that forms the lower part of the entrance and is provided with a guide groove 3a.

4.5 is a door for opening and closing the entrance/exit 1, and the upper part is appropriately suspended, and the lower part is a guide piece 4a, 5 loosely fitted in the guide groove 3a.
a is fixed, and each opens and closes in opposite directions from the center to the left and right.

(Hereinafter, only the door 4 will be explained because the doors 4 and 5 have the same structure.

) 4b is the surface painted with lacquer etc. 4c is the edge, 4
d is the back side, 6 is the thickness 1. OrrgrL~1.5rrgr
A protective joint formed in a groove shape from L aluminum or stainless steel plate, with a front part 6a, a side part 6b, and an additional part 6c.
Formed from the bottom end to the top end 4c of the door 4! It is placed along the entire length of the

6e is the cut end surface of the protective joint 6, 7 is a fastening screw, which is arranged at appropriate intervals in the length direction of the back surface 4d of the door 4 and the additional part 4c of the protective joint 6, and the protective joint 6 is shown in FIG. It is fixed to the door 4 as shown.

Rubber sheets 8 and 9 are adhesively fixed to the upper and lower ends of the side surfaces 6b.

That is, the additional part 6c of the protective joint 6 is located on the back surface 4 of the door 4.
d, it is necessary that the cut end 6e does not deform even if a force is applied to it, and that the side surface 6b does not deform even if an obstacle hits it, and the plate thickness cannot be made thinner. It had the following drawbacks.

That is, a large level difference in the protective joint 6 occurs on the surface 4b of the door 4, and there is a risk that a part of the passenger's body or clothes may be caught on the cut end surface 6e during the opening operation.

Moreover, the protective joint 6 deforms in the direction away from the door 4,
A large amount of expense is required for its repair.

However, it is necessary to consider the thickness of the door 4 when manufacturing it with and without the protective joint 6, which reduces production efficiency and increases the cost.

Further, the work of tapping screws for fixing the protective joint 6 increases the production cost.

Furthermore, if the cut end surface 6e is the size of a shear cut, dust will accumulate on the uneven parts of the fractured surface and the aesthetic appearance will be spoiled.
This part requires a lot of time to finish, and
A gap is created between the surface 4b and the cut end surface 6e, resulting in a rough product.

This invention solves the above-mentioned drawbacks and aims to provide an elmbeke door that is provided with joints, is safe, and can be manufactured at low cost.

An embodiment of this invention will be described below with reference to FIG.

In the figure, the same reference numerals as in Figures 1 and 2 indicate the same parts, and 6 is a joint made of a very thin foil-like material, for example, a board with a thickness of about 2M to 0.5m, and the material is aluminum or stainless steel. It is made of etc.

No. 10 is an adhesive such as Epokin, which becomes a hard material with little elasticity when solidified.

That is, since the entire surface of the joint 6 is bonded with the adhesive 10, the rigidity of the joint 6 itself may be very small, so it can be made at a very low cost, and the entire surface is closely attached to the door 4, so that the increase in the thickness of the door 4 is minimal. This is negligible, and there is no need to consider safety, aesthetics, and dimensional changes in the door 4 body due to the presence or absence of joints 6, and the door 4 can be made excellent.

Since the thin adhesive 10 is hard, it will not deform even if an obstacle such as a passenger collides with the joint 6.

As explained above, Riko Kanashi's idea is to make the door joints thicker than 0.
．． 5. It shall be made of an induction-resistant thin metal plate with a U-shaped cross section, and the side edge of the door body and the surface connected to the side edge.
It covers the edges of the back side and adheres to the door with a thermosetting flower-shaped adhesive such as an epoxy adhesive that, when solidified, causes a crosslinking reaction in which the molecules become entangled, resulting in a hard material with little elasticity.

As a result, even if the stiffness of the joint itself is small, it adheres tightly to the door and serves as a joint, making it inexpensive, and the increase in the overall thickness of the door is negligible, making it an excellent choice in terms of performance and safety. It is the door that will be realized.
