Definitions

  • 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.
  • 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.
  • a transparent glass window is provided in many cases.
  • such a window is often provided to an elevator installed in housing and apartments where the elevator is frequently used by women and children.
  • a rectangular opening is formed in a door panel.
  • 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.
  • a fixing member having a substantially Z-shaped cross section is arranged so as to extend along each of the two sides.
  • a mounting hole, through which a bolt is to be passed, is previously formed in the fixing member.
  • 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.
  • 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.
  • 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.
  • 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.
  • Fig. 2 is a sectional view taken along the plane A of Fig. 1 .
  • 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.
  • the glass plate 2 is made from a material that is more lightweight than conventionally used materials.
  • a fixing member 3 having a Z-shaped cross section is arranged in each of positions corresponding to two opposing sides of the glass plate 2 so as to extend vertically along each of the sides.
  • 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 each fixing member 3, and between a peripheral edge portion of the glass plate 2 and each fixing member 3.
  • the fixing members 3 are fixed onto the rear surface 1b of the door panel 1 with the elastic adhesive 4.
  • the glass plate 2 is also fixed with the elastic adhesive 4 in a place inside the opening 1c.
  • the adhesive 4 is applied directly onto the glass plate 2. Since the glass plate 2 is made from a lightweight material according to this embodiment, fixation with the adhesive 4 is adequate for maintaining a sufficient strength.
  • the opening 1c is formed in the door panel 1 by using a pressing machine or the like.
  • the glass plate 2 is fitted into the opening 1c of the door panel 1.
  • 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 the glass substrate 2 and an inner peripheral edge of the opening 1c.
  • the tape can be easily peeled off from the elastic adhesive 4 after the elastic adhesive 4 is solidified, and is attached for the purpose of preventing the elastic adhesive 4 from lying off the surface of the door panel 1 to spoil the aesthetic appearance.
  • 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 the glass plate 2 flush with each other.
  • the elastic adhesive 4 is applied in a predetermined thickness onto the side surfaces and the rear surface of the peripheral edge portion of the glass plate 2.
  • the fixing members 3 are placed on the elastic adhesive 4, and then the fixing members 3 are subjected to pressing with a predetermined pressure. Then, this state is maintained until the elastic adhesive 4 solidifies.
  • a tape similar to the one described above may be attached between each fixing member 3 and the door panel 1, and between the glass plate 2 and each fixing member 3. This is to ensure that the elastic adhesive 4 will not squeeze out and prevent positional displacement among the door panel 1, the fixing members 3, and the glass plate 2.
  • 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 the glass plate 2 and each fixing member 3 to thereby fix the glass plate 2 onto the fixing members 3, the glass 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 the glass plate 2 is effected with the adhesive 4 having elasticity, allowing vibrations generated during running of the elevator to be absorbed so that the elevator provides a comfortable ride.
  • 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.
  • the elastic 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 the glass plate 2, a portion thereof which comes into contact with the elastic adhesive 4 is applied with no coating to leave its material exposed, thus providing even firmer fixing.
  • fixing members 3 are arranged in positions corresponding to two opposing sides of the glass plate 2
  • four fixing members 3 may be provided in total in positions corresponding to four sides of the glass 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.
  • fixing members 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 fixing member 6 is bent so as to have a substantially U-shaped cross section, with its forward end portion 6a directed toward inside the opening 1c.
  • the forward end portion 6a abuts the rear surface of the glass plate 2 for positioning of the glass plate 2. That is, the glass 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 the forward end portion 6a of the fixing member 6.
  • the elastic adhesive 4 is filled in the space between the outer peripheral edge of the glass 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 an the fixing members 6 with respect to the door panel 1, and it is possible to achieve a further reduction in cost.
  • each fixing member 6 abuts the rear surface of the glass plate 2 so as to position the glass plate 2 in a predetermined position, whereby the front surface of the door panel 1 and the front surface of the glass 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 Embodiment 3.
  • a decorative molding 7 is embedded in the gap between the peripheral edge portion of the glass plate 2 and the inner peripheral edge portion of the opening 1c of the door panel 1. That is, the decorative molding 7 is arranged like a frame along the perimeter of the glass plate 2.
  • Embodiment 3 is of the same construction as Embodiment 2.
  • the provision of the decorative molding 7 renders the elastic adhesive 4 invisible, thus providing an enhanced aesthetic appearance.
  • Fig. 5 is a cross sectional view of an elevator door with a window according to Embodiment 4 of the present invention.
  • a laminated glass consisting of two glass plates is used, that is, the first glass plate 2 fitted into the opening 1c and a second glass plate 5 arranged in intimate contact with the rear surface of the first glass plate 2.
  • a principal surface of the second glass plate 5 has a larger area than that of the first glass plate 2.
  • the peripheral edge portion of the second glass plate 5 forms a protruding portion 5a protruding beyond the peripheral edge portion of the first glass plate 2 by a predetermined distance.
  • the first glass plate 2 and the second glass plate 5 may be formed integrally with each other as a single glass plate having a step portion along its perimeter.
  • the glass plate constructed as described above includes a small area portion (the first glass plate 2) fitted into the opening 1c, and a large area portion (the second glass plate 5) provided on the rear surface side of the small area portion and having a larger area than the opening 1c, the large surface area having formed therein the protruding portion 5a where at least both side edge portions of the large surface area protrudes beyond the small area portion.
  • the elastic adhesive 4 is provided between the rear surface of the door panel 1 and the protruding portion 5a.
  • the elastic adhesive 4 does not spread into the back of the first glass plate 2 and the second glass plate 5. Accordingly, there is no fear of the elastic adhesive 4 being seen through the glass plate to appear along the edge portion of the window when looking inside the window from the front side (the front surface side of the glass plate). As a result, a further improvement in aesthetic appearance can be achieved.
  • Fig. 6 is a perspective view showing the rear surface side of an elevator door with a window according to Embodiment 5 of the present invention.
  • marks 11 used for positioning of the fixing members 3 are provided on the rear side of the door panel 1.
