Abstract
An elevator door (1, 2) cooperates with a groove (4, 5) in a sill (3), the groove (4, 5) guiding a bottom (2a, 2b) of an elevator door (1, 2). The door (1, 2) has a guide shoe (6, 7) attached to the bottom thereof and has a shape which extends over a width of the door. The guide shoe (6, 7) has a front edge (6a, 7a) that is approximately flush with a front face (1b, 2b) of the door (1, 2) to prevent objects from being wedged between the bottom of the door (2a, 2b) and the sill (3).
Description
- The present invention relates to a door structure and in particular, but not exclusively to an elevator door structure.
- A conventional elevator door structure is shown in Figs. 3 and 4. Freely
slidable hoistway doors Pinshaped guide shoes bottom edges guide grooves door sill 105 in a freely slidable state. There is a clearance of approximately 5mm between the bottom edges of the doors and the surface of the door sill. - According to an aspect of the present invention, there is provided a door structure comprising:
a groove in a sill;
a guide shoe arranged at a lower end region of a door, said guide shoe cooperating with said groove to thereby guide said door,
wherein said guide shoe extends along at least part of the width of said door and is so shaped and so arranged with respect to the lower end region of the door that objects are prevented from being wedged between said lower end region of said door and said sill. - The front edge of the guide shoe may be approximately flush with the front of the aforementioned door. The guide shoe may have a shape for cooperating with a shape of the groove to guide the door and to prevent an object from wedging between the bottom of the door and the sill.
- When a passenger (specifically a child or the like) is about to enter or leave the car while the door is opening or closing, the passenger may lose his balance, and the tip of his toe may be in front of the door and touch the bottom edge of the door. Even if his toe touches the bottom edge of the door front, as guide shoe is placed between this bottom edge and the surface of the door sill, the toe is prevented from being trapped there. This door structure may be incorporated in the hoistway and/or elevator car doors.
- Thus embodiments of the present invention may provide a safe elevator structure. Furthermore embodiments of the invention may provide a structure which is able to minimise the probability that a passengers foot is injured particularly when the passenger enters or leaves the elevator.
- Viewed from a second aspect, the present invention provides a door structure having a groove in a sill, said groove guiding a bottom of a door, said door structure comprising:
a guide shoe attaching to said bottom and having a shape which ranges over a width of said door, said guide shoe having a shape for cooperating with a shape of said groove to guide said door and for preventing an object from wedging between said bottom of said door and said sill. - Viewed from a third aspect, the present invention provides an elevator door structure having a groove in a sill, said groove guiding a bottom of an elevator door, said structure comprising:
a guide shoe attaching to said bottom and having a shape which ranges over a width of said door, said guide shoe having a front edge that is approximately flush with a front face of said door to prevent objects from being wedged between said bottom of said door and said sill. - An embodiment of the present invention will now be described by way of example with reference to the accompanying drawings in which:
- Fig. 1 is a perspective view which illustrates an elevator door structure embodying the present invention;
- Fig. 2 is a sectional view of the door structure of Figure 1;
- Fig. 3 is a perspective view of the conventional door structure; and
- Fig. 4 is a sectional view of the door structure of Figure 3.
- An embodiment of the invention will be explained based on Figures 1 and 2 which illustrate an example of an elevator door structure.
- In Figs 1 and 2, the
doors sill 3 that has twoguide grooves - Each door has a
guide shoe bottom edges guide grooves - The
guide shoes front edges 6a, 7a are almost flush with the front of the doors lb, 2b. Thus, on the front side of the doors, the guide shoes are placed between the bottom edges of the doors and the surface of thedoor sill 3 and the clearance that existed in the prior art has disappeared. Passage holes (not illustrated in the figures) are formed on the bottom of the guide grooves. These holes allow dirt to pass through to prevent that dirt from accumulating in the groove and jamming the free sliding of the doors. - Although the invention has been shown and described with respect to a best mode embodiment thereof, it should be understood by those skilled in the art that various other changes, omissions and additions in the form and detail thereof may be made therein without departing from the scope of the invention. While this embodiment has been described in relation to hoistway doors, needless to mention, it can also be applied to the door structure on the car side.
