It is a cross-sectional view which shows the function of a buffer member. It is a cross-sectional view which shows the other function of a buffer member.

  Hereinafter, embodiments of a door device and an elevator device according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the elevator apparatus of the present embodiment is a lifting body that lifts and lowers a hoistway 1 formed in a building, that is, a car 2 and a counterweight 3, and both ends are connected to the upper part of the hoistway 1. At the same time, a rope 4 on which the car 2 and the counterweight 3 are suspended, and a hoisting machine 5 that drives the sheave 5a around which the rope 4 is wound to move the car 2 and the counterweight 3 up and down. Have.

  As a door device, as shown in FIG. 2, it is suspended on the door rail 7 by a door rail 7 installed on the door rail frame 6 and hangers 8a and 8b, and the hanger rollers 9a, 9b, 9c and 9d roll on the door rail 7. The doors 10a and 10b that open and close laterally, a motor (not shown) that drives the doors 10a and 10b to open and close, a sill 11 that is laid in parallel with the door rail 7, and a lower part of the doors 10a and 10b are attached to the sill 11 The guide shoes 12a and 12b that allow the doors 10a and 10b to open and close while maintaining vertical by sliding smoothly in the grooves provided in the door, and at least one of the doors 10a and 10b, for example, And a shock-absorbing member 13 that is attached to the door-side end of the door 10a and reduces the door-stop sound when the doors 10a and 10b are closed. .

  As shown in FIG. 3, two insertion holes 14a and 14b are provided side by side in the thickness direction of the door-contacting side end of the door 10a.

  The buffer member 13 has the same hardness as a whole and is formed of a flexible material, such as rubber, and is inserted through the insertion holes 14a and 14b as shown in FIGS. Two conical margins 13a, 13b having a substantially conical shape, for example, a truncated cone shape, the center of which is eccentrically disposed outward in the thickness direction with respect to the centers of the insertion holes 14a, 14b The buffer surface 13c disposed at the end of the door 10a on the door contact side, the hooking margin portions 13a, 13b, and the buffer surface 13c are connected, and the length dimension is substantially the same as the depth dimension of the insertion holes 14a, 14b. The connecting portions 13d and 13e are provided.

  The diameters of the widest portions of the bottom surfaces of the hooking margin portions 13a and 13b are larger than the diameters of the insertion holes 14a and 14b, and as described above, this portion is offset from the insertion holes 14a and 14b. By paying attention, the allowances 13a1 and 13b1 are formed.

  The outer edge of the buffer surface 13c in the thickness direction is chamfered and provided with an inclination or roundness.

  In the present embodiment, when the buffer member 13 is attached to the door-contacting side end of the door 10a, the hooking margins 13a and 13b are opposed to the insertion holes 14a and 14b provided along with the door 10a, and the hooking margin 13a. , 13b are pushed into the insertion holes 14a, 14b. At this time, since the hook margin portions 13a and 13b have a truncated cone shape, the hook margin portions 13a and 13b can be pushed into the insertion holes 14a and 14b relatively easily. Once the hooking portions 13a and 13b are inserted through the insertion holes 14a and 14b, the hooking allowances 13a1 and 13b1 are hooked on the back surface 10a1 of the door, and the buffer panel 13 is sandwiched between the buffering surface 13c and the hooking allowances 13a1 and 13b1. It is attached to the door 10a.

  Even if a cart entering or leaving the car 2 or a passenger's luggage hits the buffer member 13, the outer edge of the buffer surface 13c is rounded, so it is easy to miss the impact force. Further, since the hook margins 13a1 and 13b1 are formed in the hook margin portions 13a and 13b toward the outer side in the thickness direction of the door 10a, for example, as shown in FIG. In contrast, even if it hits in the direction of the arrow 15, the hook allowance 13b1 is pressed against and engaged with the door panel back surface 10a1, and the hook allowance 13b is prevented from falling off the insertion hole 14b.

  On the other hand, the hooking margin portions 13a and 13b are on the inner side in the thickness direction of the door 10a and are substantially flush with the connecting portions 13d and 13e. As a result, when the buffer member 13 is removed for reasons of replacement or the like, as shown in FIG. 6, by pulling the vicinity of the middle of the buffer surface 13c in the direction of the arrow 16, 14b and can be removed relatively easily.

  According to the present embodiment, even if the buffer member 13 is entirely formed with the same hardness, by devising its shape, it is possible to make it difficult to drop off when a cart or luggage hits when getting on and off, As a result, it is possible to improve the elevator quality while reducing the cost. Further, since the buffer member 13 can be easily removed at the time of replacement, the workability of maintenance work can be improved.

  In the above-described embodiment, the example in which the buffer member 13 is attached to the door-contact side end portion of the door 10a is shown, but it goes without saying that the buffer member can be attached to both the doors 10a and 10b or the door 10b. . In addition, the hanging margin portions 13a and 13b are located on the inner side in the thickness direction of the door 10a and are substantially flush with the connecting portions 13d and 13e. However, the hanging margin portions 13a and 13b are not drawn. You may form the allowance which hangs on the back surface of a door panel in this part to such an extent that it does not cause trouble.
