Abstract
Description
- The present invention relates to an elevator door provided with a window, and more specifically to an improvement of an elevator door with a window of the type in which a glass plate is fitted in a door panel.
- In recent years, a window is often provided to a door for opening/closing the entrance of an elevator car. This is from the viewpoints of releasing passengers from a sense of confinement of a car and crime prevention, and a transparent glass window is provided in many cases. In particular, such a window is often provided to an elevator installed in housing and apartments where the elevator is frequently used by women and children.
- For production of a conventional elevator door with a window, first, a rectangular opening is formed in a door panel. Then, a glass plate having a surface area slightly larger than that of the opening is prepared, and the glass plate is arranged so as to close the opening from the rear surface side of the door panel. Then, in each of positions corresponding to two opposing sides of the glass plate thus arranged, a fixing member having a substantially Z-shaped cross section is arranged so as to extend along each of the two sides. Amounting hole, through which a bolt is to be passed, is previously formed in the fixing member. On the other hand, a mounting bolt is previously provided in a predetermined position on the rear surface of the door panel. The mounting bolt is passed through the mounting hole so as to bring the fixing member into engagement with an edge portion of the glass plate, and the fixing member is fastened in position with a nut. Then, both edge portions of the glass plate are fixed in position while sandwiched between an edge of the opening and the fixing member.
- With the elevator door provided with a window constructed as described above, light from the outside enters inside the car, thus offering a sense of openness. In addition, the use of a transparent glass plate allows passengers to look outside from inside the car and also look inside the car from the outside, and therefore crime prevention effects can be anticipated.
- With the conventional elevator door with a window constructed as described above, however, it is necessary to provide a mounting bolt upright on the rear surface of the door panel in advance, and also to form the mounting hole on the fixing member. This leads to an increase in the requisite manufacturing time and also in the number of parts, resulting in an increase in cost. Further, the front surface of the door panel and the front surface of the glass plate are not made flush with each other, which detracts from the aesthetic appearance of the elevator door.
- The present invention is made to solve the problems described above, and an object thereof is to provide an elevator door with a window which allows a reduction in cost for its ease of manufacture and reduced number of parts and also enables an improvement in terms of design.
- An elevator door with a window of the present invention comprises: a door panel having an opening; a fixing member provided in an edge portion of the opening and extending on a rear side of the door panel; a transparent plate having substantially the same shape as the opening and fitted into the opening so as to close the opening; and an elastic adhesive which is arranged between a rear surface of the door panel and the fixing member while in direct contact with both the rear surface of the door panel and the fixing member to fix the fixing member onto the rear surface of the door panel, and which is arranged between a peripheral edge portion of the transparent plate and the fixing member while in direct contact with both the peripheral edge portion of the transparent plate and the fixing member to fix the transparent plate onto the fixing member.

-
- Fig. 1 is a perspective view, as seen from a rear surface side, of an elevator door with a window according to Embodiment 1 of the present invention. Besides, Fig. 2 is a sectional view taken along the plane A of Fig. 1. Referring to the figures, a rectangular opening 1c is provided in substantially the central portion of a door panel 1 of an elevator. Fitted into the opening 1c is a
glass plate 2, which is a transparent rectangular plate having an outer shape that is somewhat smaller in size than the opening 1c. Theglass plate 2 is made from a material that is more lightweight than conventionally used materials. - On a rear surface 1b side of the door panel 1, a
fixing member 3 having a Z-shaped cross section is arranged in each of positions corresponding to two opposing sides of theglass plate 2 so as to extend vertically along each of the sides. As well illustrated in the cross sectional view of Fig. 2, a urethane or silicone adhesive 4, which exhibits elasticity when solidified, is filled in between the rear surface 1b of the door panel 1 and eachfixing member 3, and between a peripheral edge portion of theglass plate 2 and eachfixing member 3. Thefixing members 3 are fixed onto the rear surface 1b of the door panel 1 with theelastic adhesive 4. Theglass plate 2 is also fixed with theelastic adhesive 4 in a place inside the opening 1c. In the peripheral edge portion of theglass plate 2, a surface thereof which comes into contact with theelastic adhesive 4 is not applied with coating etc, thus leaving its material exposed. That is, in place of applying coating on theglass plate 2 and then applying theadhesive 4 thereon, theadhesive 4 is applied directly onto theglass plate 2. Since theglass plate 2 is made from a lightweight material according to this embodiment, fixation with theadhesive 4 is adequate for maintaining a sufficient strength. - Next, a method of manufacturing the door with a window is described. First, the opening 1c is formed in the door panel 1 by using a pressing machine or the like. Next, the
glass plate 2 is fitted into the opening 1c of the door panel 1. Then, a tape that exhibits excellent releasability is attached onto the front surface 1a side of the door panel 1 so as to close a gap formed between an outer peripheral edge of theglass substrate 2 and an inner peripheral edge of the opening 1c. The tape can be easily peeled off from theelastic adhesive 4 after theelastic adhesive 4 is solidified, and is attached for the purpose of preventing theelastic adhesive 4 from lying off the surface of the door panel 1 to spoil the aesthetic appearance. - Next, in this state, the door panel 1 is placed on a surface plate or a flat workbench with its front surface 1a side down. This is to make the front surface 1a of the door panel 1 and a
front surface 2a of theglass plate 2 flush with each other. Then, theelastic adhesive 4 is applied in a predetermined thickness onto the side surfaces and the rear surface of the peripheral edge portion of theglass plate 2. Further, thefixing members 3 are placed on theelastic adhesive 4, and then thefixing members 3 are subjected to pressing with a predetermined pressure. Then, this state is maintained until theelastic adhesive 4 solidifies. - Note that, at this time, a tape similar to the one described above may be attached between each
fixing member 3 and the door panel 1, and between theglass plate 2 and eachfixing member 3. This is to ensure that theelastic adhesive 4 will not squeeze out and prevent positional displacement among the door panel 1, thefixing members 3, and theglass plate 2. - Further, as another method of manufacturing the door with a window, for example, it is also possible to attach the above-described tape after arranging the
glass plate 2 and thefixing members 3 in predetermined positions, and fill theelastic adhesive 4 into a slight space formed between theglass plate 2 and thefixing members 3. - Since the elevator door with a window constructed as described above includes the urethane or silicon
elastic adhesive 4 which is provided between, while in direct contact with both, the peripheral edge portion of theglass plate 2 and eachfixing member 3 to thereby fix theglass plate 2 onto thefixing members 3, theglass plate 2 can be fixed onto the door panel 1 without using a mounting bolt and a mounting nut. Further, the time required for providing the mounting bolt and the time required for forming a mounting hole can be reduced, making it possible to achieve a reduction in cost. In addition, the fixing of theglass plate 2 is effected with theadhesive 4 having elasticity, allowing vibrations generated during running of the elevator to be absorbed so that the elevator provides a comfortable ride. Further, the front surface of the glass plate 1 is arranged flush with the front surface of the door panel 1, so that an improvement in terms of design is realized. Further, as theelastic adhesive 4 is provided between the two members to be bonded so as to be in direct contact with both the members, firm and secure fixing between the two members is provided. Further, in the peripheral edge portion of theglass plate 2, a portion thereof which comes into contact with theelastic adhesive 4 is applied with no coating to leave its material exposed, thus providing even firmer fixing. - Note that, while in this embodiment two
fixing members 3 are arranged in positions corresponding to two opposing sides of theglass plate 2, fourfixing members 3 may be provided in total in positions corresponding to four sides of theglass plate 2, with one for each of the four sides. - Fig. 3 is a cross sectional view of an elevator door with a window according to
Embodiment 2 of the present invention. In this embodiment, fixingmembers 6 are integrated with the door panel 1. - A manufacturing method for the elevator door is hereinafter described. Press working is performed such that when forming the opening 1c in the door panel 1 by using a pressing machine, the fixing
members 6 are formed at the same time along the peripheral edge of the opening 1c. Each fixingmember 6 is bent so as to have a substantially U-shaped cross section, with itsforward end portion 6a directed toward inside the opening 1c. Theforward end portion 6a abuts the rear surface of theglass plate 2 for positioning of theglass plate 2. That is, theglass plate 2 is arranged such that its front surface becomes flush with the front surface of the door panel 1, with its rear surface abutting theforward end portion 6a of the fixingmember 6. Then, theelastic adhesive 4 is filled in the space between the outer peripheral edge of theglass plate 2 and the inner peripheral edge of the opening 1c. - The elevator door with a window constructed as described above provides the following effects in addition to the effects of Embodiment 1. That is, the fixing
members 6 are integrated with the door panel 1, whereby there is no need to perform positioning on the fixingmembers 6 with respect to the door panel 1, and it is possible to achieve a further reduction in cost. - In addition, the
forward end portion 6a of each fixingmember 6 abuts the rear surface of theglass plate 2 so as to position theglass plate 2 in a predetermined position, whereby the front surface of the door panel 1 and the front surface of theglass plate 2 can be easily made flush with each other without placing the door panel 1 on a surface plate or the like as in Embodiment 1, making it possible to achieve an improvement in workability and also a reduction in cost. - Fig. 4 is a cross sectional view of an elevator door with a window according to
