TECHNICAL FIELD
[0001] The present disclosure relates to a universal sill and an elevator including the universal sill.
BACKGROUND
[0002] The use of elevators is very common. However, with the aging of elevators and the upgrading of elevator technology, the problem of replacing elevators is faced. The floor of the elevator landing needs a sill to guide a landing door to open and close. When replacing the elevator, because the basic size of the old sill is fixed, it is difficult to find the sill with the same basic size and suitable for the new elevator in the market, which leads to the difficulty in installing the landing door at the elevator replacement site.
SUMMARY
[0003] In view of the above problems, according to a first aspect of the present disclosure, a universal sill is provided and includes: a middle part, comprising a guide rail configured to guide a door to open and close in a length direction; and one or more additional parts, configured to be assembled to the middle part, a total width of the middle part and the one or more additional parts after assembly defines a width of the universal sill, and the width of the universal sill varies according to the one or more additional parts actually assembled.
[0004] The universal sill according to the present disclosure can have different widths, so that when replacing the elevator, the universal sill can well adapt to the sizes of different old sills.
[0005] The universal sill according to the present disclosure may have one or more of the following features.
[0006] According to an embodiment, the one or more additional parts comprise one or more left parts and/or one or more right parts, the one or more left parts are configured to be assembled to the middle part from a left side, and the one or more right parts are configured to be assembled to the middle part from a right side. The one or more additional parts can be one of the following cases: one or more left parts, one or more right parts, one or more left parts and one or more right parts, which can be flexibly selected, so as to form different sills with different total widths and guide rails at different positions.
[0007] According to an embodiment, a part of the additional parts closest to the middle part is assembled to the middle part through a dovetail groove provided in the middle part. The design of the dovetail groove is convenient for assembly.
[0008] According to an embodiment, an outer part of the additional parts is assembled to an adjacent inner part through a dovetail groove arranged on an outer side of the adjacent inner part. The design of the dovetail groove is convenient for assembly.
[0009] According to an embodiment, an inner upper end and an inner lower end of the additional parts are provided with mating convex parts protruding inward, which are configured to be in interference fit with mating concave parts arranged on an outer side of an adjacent inner part or the middle part. It is not easy for the two mated parts to slide relatively, and a relatively flat sill surface can be obtained to increase passenger friendliness and aesthetics.
[0010] According to an embodiment, the additional parts are symmetrical about a horizontal plane bisecting a height of the additional parts. Through the symmetrical design, the left part can act as the right part, and the right part can act as the left part, as long as it is turned by 180 degrees, so the design can reduce the specification number of parts.

[0021] In the following description, a direction of door opening and closing is defined as a length direction, the direction perpendicular to the length direction in the horizontal plane is defined as the width direction, and the vertical direction perpendicular to the horizontal plane is defined as the height direction.
[0022] Fig. 1 is a cross-sectional view of a universal sill according to an embodiment of the present disclosure. The universal sill is configured to be installed at the floor of an elevator landing, thereby guiding a landing door provided at the landing. Referring to Fig. 1, the universal sill according to the present disclosure includes a middle part C and an additional part directly or indirectly assembled to the middle part. According to the additional part assembled to the middle part from the left side or the right side, the type of the additional part can be divided into the left part and the right part. Fig. 2 is a view of the parts before assembly, and Fig. 3 is a view of the parts after assembly. Based on the middle part C, a side close to the middle part C is called the inner side, and a side away from the middle part C is called the outer side.
[0023] The middle part C includes a groove extending in the length direction, and the groove is formed as a guide rail for guiding a door to open and close. The middle part C further includes a fastener accommodating part, the fastener accommodating part includes an opening that opens downward and the width of the opening is smaller than the width of the fastener accommodating part, and the fastener accommodating part is configured to allow a screw to fasten the middle part C to the floor. Specifically, the screw head of the screw may be accommodated in the fastener accommodating part and the width of the screw head is greater than the width of the opening, and the shaft portion of the screw may be fastened to the floor through the opening, thereby fastening the middle part C to the floor. Dovetail grooves 1 are arranged at the outer sides of the left and right ends of the middle part C for assembling the left part and the right part.
[0024] One or more additional parts can be provided, for example, any number of left parts, any number of right parts, any number of left parts and any number of right parts.
[0025] If the left part is assembled, one or more left parts can be provided, and the left parts are configured to be assembled to the middle part C from the left side. If the right part is assembled, one or more right parts can be provided, and the right parts are configured to be assembled to the middle part C from the right side. The inner sides of the left part and the right part are provided with protrusions, and the protrusions are configured to match with the dovetail groove 1 on the outer side of the middle part C or an adjacent inner part, so that the left part or the right part is assembled to the middle part C or the adjacent inner part. For example, the left part closest to the middle part C among the one or more left parts is assembled to the middle part C through the protrusion arranged on the inner side (here, the right side) and the dovetail groove 1 arranged on the left side of the middle part C, and the right part closest to the middle part C among the one or more right parts is assembled to the middle part C through the protrusion arranged on the inner side (here, the left side) and the dovetail groove 1 arranged on the right side of the middle part C, the outer part of the one or more left parts and one or more right side parts is assembled to the adjacent inner part through a protrusion arranged on the inner side of the outer part and the dovetail groove 1 arranged on the outer side of the adjacent inner part. The outer sides of the left parts and the right parts may or may not be provided with dovetail grooves 1, and the part without the dovetail groove 1 can only be assembled to the outermost side of the left side or the right side.
[0026] Additional parts (left parts and right parts) may be fastened to the middle part C by screws, as shown in Fig. 1.
[0027] The inner upper end and the inner lower end of the additional parts (the left part and the right part) are provided with mating convex parts 2 protruding inward, which are configured to be in interference fit with mating concave parts 3 arranged on the outer side of the adjacent inner part or the middle part C, so that it is not easy for the two parts that are mated to slide relatively, and a relatively flat sill surface can be obtained to increase passenger friendliness and aesthetics.
[0028] The additional parts (left parts and right parts) are symmetrical about a horizontal plane bisecting a height of the additional parts. Through the symmetrical design, the left part can act as the right part, and the right part can act as the left part, as long as it is turned by 180 degrees, so the design can reduce the specification number of parts.
[0029] In order to adapt to different widths when replacing the sill, one or more left parts can be assembled on the left side of the middle part C, and/or one or more right parts can be assembled on the right side of the middle part C. Because the width of the universal sill is limited by the total width of the one or more left parts, the middle part C and one or more right parts which are assembled, different total widths can be obtained by changing the number of left parts and right parts, that is, the width of the universal sill varies according to one or more left parts and/or one or more right parts which are actually assembled.
[0030] In order to more easily adapt to different widths and limit the number of parts to be processed when replacing the sill, in addition to making the left part and the right part symmetrical up and down, the left part and the right part can be defined with a certain number of specifications under the condition that the width of the middle part C is fixed. For example, the left part and the right part are selected from a first part A and a second part B. For example, the first part A has a plurality of selectable first widths, and the second part B has a fixed second width. For example, the plurality of selectable first widths are 10mm, 15mm and 20mm, and the second width is 5 mm. Then, by selecting any number of first parts A and/or second parts B on the left and right sides, a variety of different total widths can be achieved. In the embodiment of Fig. 1, two first parts A are selected on the left side and the second part B is selected on the right side, that is, the assembled sill is A+A+C+B. It should be noted that the number of selected parts on the left and right sides can be arbitrary, for example, the assembled sill can be A+C, C+B, A+C+A, B+A+C+B, B+A+C+A+A+B, etc.
[0031] Optionally, the outer side of the first part A is provided with a dovetail groove 1, and the outer side of the second part B is not provided with a dovetail groove 1. In this case, the second part B can only be provided on the outermost side on the left or right side. Moreover, in this case, because the second part B is arranged at the outermost side, the outer side of the second part B may not be provided with the mating concave part 3.
[0032] In order to adapt to different heights when replacing the sill, the additional part and the middle part C can have selectable heights, for example, all of them have a height of 20mm, 25mm or 30 mm.
