[0088] Work

[0089] The following is given as Figure 2 , Figure 4 and Figure 5 The opening operation method of the guide assembly for use in a center-parted elevator door according to the present invention is shown as follows:

[0090] Step 1: The lock hook 3 positioned on the edge of the third slider plate 2c is disengaged from the lock tongue 4 for mechanically unlocking the third slider plate 2c from the second slider plate 2b, and the pulleys 7a, 7b will rotate clockwise.

[0091] Step 2: The slider plates 2a, 2b, 2c, 2d slide horizontally away from the center on the surface of the hollow guide rail guides 1a, 1b with the help of two upper rollers 14a, 14b and two reaction rollers 15a, 15b, and the two upper rollers 14a, 14b and the two reaction rollers 15a, 15b are respectively positioned at the top and bottom of the first hollow guide rail guide 1a and the second hollow guide rail guide 1b.

[0092] Step 3: The stoppers 8a, 8b positioned below the end brackets 6a, 6b limit the movement of the slider plates 2a, 2b, 2c, 2d, respectively.

[0093] Step 4: The return spring 11 is extended due to the sliding movement of the slider plates 2a, 2b, 2c, 2d.

[0094] Step 5: The pulleys 7a, 7b and the synchronization rope 12 connected between the pulleys 7a, 7b will ensure that the slider plates 2a, 2b, 2c, 2d slide and move away from the center at equal distances on the left and right hand sides in a synchronized manner.

[0095] The following is given as Figures 2 to 6 The closing operation method of the guide assembly for use in a center-parted elevator door according to the present invention is shown as follows:

[0096] Step 1: The pulleys 7a, 7b and the synchronization rope 12 connected between the pulleys 7a, 7b will ensure that the slider plates 2a, 2b, 2c, 2d slide and move towards the center by equal distances on the left and right hand sides in a synchronized manner.

[0097] Step 2: The slider plates 2a, 2b, 2c, 2d slide horizontally toward the center on the surface of the hollow guide rail guides 1a, 1b with the help of two upper rollers 14a, 14b and two reaction rollers 15a, 15b, and the two upper rollers 14a, 14b and the two reaction rollers 15a, 15b are respectively positioned at the top and bottom of the first hollow guide rail guide 1a and the second hollow guide rail guide 1b.

[0098] Step 3: The return spring 11 is compressed due to the sliding movement of the slider plates 2a, 2b, 2c, 2d toward the center.

[0099] Step 4: The lock hook 3 positioned on the edge of the third slider plate 2c engages with the lock tongue 4 to mechanically lock the second slider plate 2b with the third slider plate 2c, and the pulleys 7a, 7b will rotate counterclockwise.

[0100] like Fig.12 as well as Fig. 9 and Fig.10 As shown, the hollow rail guides 1, 1a, 1b used in the guide assembly for the mid-split and telescopic opening type elevator doors have the following dimensions: The hollow rail guide 1 is one of the key features of the present invention. It is a defined component comprising a single tubular component having a parallel central tubular portion 20, which expands toward the edge into a circular profile or annular structure and looks like a dumbbell. The annular structure having a first end 21 and a second end 22 has the same configuration, wherein the two ends 21, 22 have a length of 40 mm. The annular structure has an inner radius R5, and the width of the tubular parallel structure 20 in the center is approximately 1 mm to 3 mm.

[0101] For exemplary purposes only, the tubular parallel portion of the hollow rail guide is 30 mm and the length of the hollow rail guide from one end to the other is 40 mm. The hollow rail guide is a structural member that is both joined to the slider plate and acts as a rail guide. This is a key difference compared to the background art.

[0102] Example of a hollow rail guide 1:

[0103] Width 1 to 3 mm

[0104] Height / length 40 mm

[0105] Top and bottom rings with radius R5

[0106] like Fig.13 As shown, the slider plates (2a, 2b, 2c, 2d) used in the guide assembly for the mid-split and telescopic opening elevator doors have the following dimensions:

[0107] Width 120 mm

[0108] Length 139 mm

[0109] Advantages of the present invention:

[0110] Since a plurality of slider plates 2a, 2b, 2c, 2d are used in the guide assembly of both the center-split type and the telescopic opening type elevator doors, the guide assembly eliminates the need for variable sizes for different landing door mechanisms.

[0111] In the present invention, the slider plate is not a single piece, it is multiple pieces, preferably two pieces. It has the advantage of being custom made for doors of any size.

[0112] The hollow rail guides 1a, 1b used in the guide assembly for the center-split type and telescopic opening type elevator doors integrate two functions such as guiding and supporting using only one component.

[0113] An integrated cover 5 for a guide assembly for use in an elevator door helps prevent debris at the job site during installation and operation of the landing door mechanism and maintains the functionality of the return spring retainer mechanism.

[0114] Therefore, the present invention achieves design improvement and component reduction of a guide assembly for use in an elevator door without affecting the function of the elevator landing mechanism, and also integrates the guiding function and the supporting function by using one hollow guide rail component.

[0115] Although what are considered to be preferred embodiments of the present invention have been shown and described, it should of course be understood that various modifications and changes in form or detail can be easily made without departing from the spirit of the present invention. Therefore, it is intended that the present invention is not limited to the exact form described and shown, but should be configured to cover all modifications that may fall within the scope of the appended claims. Additional embodiments can also be obtained by combining two or more dependent claims.

[0116] It is obvious to those skilled in the art that the purpose of the present invention has been achieved by providing the above invention. However, various changes can be made to the structure of the present invention without departing from the concept of the present invention. Therefore, the scope of the present invention is determined by the terms of the attached claims and their legal equivalents.
