Description

  TECHNICAL FIELD The present invention relates to an elevator door, which is an elevator door that has a transparent plate material at the center and wide vertical rods on both sides of the transparent plate material to improve design. The present invention relates to an elevator door that can be easily manufactured because it is crimped and fixed, and the transparent plate can be easily replaced.

Conventionally, doors with windows have been widely known and used as elevator doors.
JP-A-6-144760 (5th page, FIG. 1)

  The elevator door with a window described in the above-mentioned patent document 1 is for making a hole in a steel door and attaching a transparent plate material, and preventing the appearance from being cut and preventing the danger caused by the cut surface. . FIG. 4 shows this conventional elevator door with a window, and is a front view showing a state in which a hole is formed in a steel door 5 and a transparent plate 1 is attached. On the other hand, the present invention provides the same effect because the transparent plate material comes to the upper and lower sides of the elevator door without providing a window, and the design property is improved by arranging the transparent plate material at the center of the door. is there.

  In order to solve the above-described problems, the first characteristic configuration of the elevator door according to the present invention is that, as described in claim 1, the left and right ends of the transparent plate are sandwiched between vertical sides and the left and right ends of the transparent plate are The front side of the vertical plate is covered with the front side long piece, and the left and right end surfaces of the transparent plate material are sandwiched by the ridges protruding inward from the back side of the front side long piece. In addition to disposing the connecting member of the mold, the transparent plate member is pressure-bonded to the back surface of the front side long piece of the vertical rod at the center of the connecting member, and the left and right bent pieces of the connecting member are joined to the protrusion. is there.

  The second characteristic configuration is that, as described in claim 2, in addition to the above-described characteristic configuration, the vertical rod is formed by bending a steel plate.

  The third characteristic configuration is that, as described in claim 3, the vertical gutter is formed of an extrusion mold material.

  The fourth characteristic configuration is that a cushion material is disposed between the transparent plate and the connecting material as described in claim 4.

  The elevator door according to claim 1 has the above-described configuration, and is provided with a transparent plate material in the center portion and wide vertical fences on both sides of the transparent plate material, and the center portion of the door has a transparent plate material from the upper part to the lower part. An elevator door with good aesthetics is obtained, and the width of the door can be changed variously depending on the width of the transparent plate and the length of the connecting material.

  The elevator door according to claim 2 is the above-mentioned composition, and since it is formed by bending a steel plate, it can be manufactured in large quantities and at low cost.

  The elevator door according to claim 3 has the above-described configuration, and since it is an extrusion mold material, the thickness of the main part of the vertical shaft can be increased, so that the strength of the door can be increased.

  Since the elevator door of Claim 4 is the said structure, even when the load of a horizontal direction is applied to a transparent board | plate material, it can prevent that a transparent board | plate material is damaged by a cushion material.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 3 show an embodiment of an elevator door according to the present invention. FIG. 1 shows the elevator door 5 as viewed from the front. A transparent plate 1 is provided at the center, and both left and right ends of the transparent plate 1 are sandwiched between vertical frames 2 and 2.

  As shown in FIG. 2, the elevator door 5 according to the present invention is a protrusion in which the front surfaces of the left and right ends of the transparent plate 1 are covered with the front side long piece 21 of the vertical rod 2 and protrudes inward from the back side of the front side long piece 21. The right and left end surfaces of the transparent plate material are sandwiched by the strips 23, and the U-shaped connecting material 3 is disposed on the upper and lower portions of the back surface of the transparent plate material 1. The left and right bent pieces 31, 31 of the connecting member 3 are bonded to the ridge 23 by pressure bonding to the back surface of the front side long piece 21 of the bag. The vertical rod 2 has a short piece 22 formed in parallel with the front long piece 21 for reinforcement. Specifically, the connecting configuration is such that the transparent plate 1 is crimped to the back side of the front long piece 21 of the vertical rod 2 at the center of the connecting material 3, and the ridge 23 of the vertical rod 2 and the bent piece 31 of the connecting material 3. Are connected by a bolt 4.

  Since the front side long piece 21 of the vertical fence 2 covers the left and right ends of the transparent plate 1 as viewed from the front of the door, the end of the transparent plate 1 is fixed without being seen from the front, and is connected to the width of the transparent plate 1 By adjusting the length of the material 3, it can be applied to the elevator door 5 having various widths. The protrusions 23 of the vertical rod 2 are preferably provided at a substantially intermediate position between the leading edge of the front long piece 21 and the leading edge of the short piece 22 of the vertical rod 2. If the ridge 23 is close to the leading edge of the front side long piece 21 of the vertical rod 2, the portion covering the transparent plate 1 becomes small, and the transparent plate 1 may be detached when a large external force is applied to the transparent plate 1. Also, if the ridge 23 is formed at a position far away from the front edge of the front long piece 21 of the vertical rod 2, there is a short piece 22 of the vertical rod 2, so that the bolt 4 is inserted from the inside of the vertical rib 2 of the vertical rod 2 This is because it becomes difficult to combine them.

  The vertical gutter 2 can be formed by bending a steel plate. In many cases, the steel sheet is formed by bending with a roll, so that it can be produced in large quantities and at low cost. The vertical gutter 2 may be an extruded mold such as aluminum. In this case, since the thickness can be changed depending on the part, the front side long piece 23 of the vertical rod 2 to which an external force is applied can be thickened, and the short piece 22 of the vertical rod 2 can be formed thin, and the ridge 23 provided on the front side long piece 21 of the vertical rod 2 By thickening, it is possible to thread the ridge, and it is possible to fix the screw without using the bolt 4, and the assembly of the elevator door 5 becomes easy.

  As shown in FIG. 3, when the cushioning material 32 is disposed between the transparent plate 1 and the connecting material 3, the external force applied to the transparent plate 1 can be absorbed and damage can be prevented. The size of the cushion material 32 is substantially the same as the middle part of the connecting material 3 and is arranged so as not to protrude from the connecting material 3.

  Since the elevator door 5 according to the present invention has the above-described configuration, almost the entire surface of the elevator door 5 can be made of the transparent plate 1, and various designs can be achieved by changing the width of the front side long piece 21 of the vertical rod 2. The elevator door 5 can be configured.

  And unlike the conventional elevator door 5 shown in FIG. 4 where the lower part of the elevator door 5 is not visible, the elevator door of the present invention is such that the transparent plate 1 is from above the elevator door 5 except for the connecting material 4 portion. Since it is up to the bottom, even when a child or a person in a wheelchair gets on and off, the presence of the person can be recognized from the other party and the danger of a collision at the time of getting on and off can be prevented.

  Since the elevator door 5 is arranged and moved back to back, the back side of the elevator door 5 does not require any special makeup, and since it is formed by connecting with bolts 4 or the like, it can be easily replaced. .
