[0035] (Elevator door cover assembly according to the first embodiment of the present invention)

[0036] Figure 1a is a perspective schematic diagram showing an elevator door cover 1 of an elevator door cover assembly according to a first embodiment of the present invention; Figure 1b is a perspective schematic diagram showing a fastener 2 of an elevator door cover mounting assembly of an elevator door cover assembly according to a first embodiment of the present invention; Figure 1c It shows Figure 1b A schematic side view of the fastener 2; Figure 1d It shows Figure 1aThe right frame 12 of the elevator door frame 1 and Figure 1b A schematic top view of the fastener 2 of the elevator door sleeve installation assembly after being installed; Figure 1e It shows Figure 1d An enlarged schematic diagram of area S in FIG.

[0037] like Figures 1a to 1e As shown, the elevator door cover assembly according to the first embodiment of the present invention comprises an elevator door cover 1 and an elevator door cover installation assembly that can be assembled together. The elevator door cover installation assembly is used to be fixedly installed in the elevator door opening, and the elevator door cover installation assembly is inserted and installed for the elevator door cover 1, so that the elevator door cover 1 can be fixedly installed at any predetermined position of the elevator door opening.

[0038] Specifically, in this embodiment, if Figure 1a As shown, the elevator door frame 1 includes an upper beam 11, a right frame 12 and a left frame 13. The upper beam 11, the right frame 12 and the left frame 13 are preferably assembled together in a detachable manner to form the elevator door frame 1, and the right frame 12 and the left frame 13 are respectively connected to the two ends of the upper beam 11 in the left-right direction W. The upper beam 11 extends along the left-right direction W as a whole, and the right frame 12 and the left frame 13 extend along the up-down direction H as a whole. Further, the upper beam 11, the right frame 12 and the left frame 13 are all made of galvanized steel sheets, which are the most preferred materials selected in consideration of factors such as manufacturing cost and structural strength. Other materials can also be used as the manufacturing material of the elevator door frame 1 according to the present invention according to actual needs.

[0039] In the present embodiment, the upper beam 11 extends in the left-right direction W as a whole and has a shape symmetrical with respect to a center line in the left-right direction W. The upper beam 11 has an upper beam front panel, which extends in the up-down direction H and the left-right direction W and is preferably formed with a decorative pattern. Further, for the convenience of manufacturing, in the present embodiment, the upper beam front panel is formed by a galvanized steel plate.

[0040] In this embodiment, the structure of the right frame 12 and the structure of the left frame 13 are symmetrical about the center line of the elevator door frame in the left-right direction W. Figure 1a and Figure 1d The structures of the right frame 12 and the left frame 13 will be described.

[0041] like Figure 1a and Figure 1d As shown, in this embodiment, the right frame 12 has a right frame front panel 121 and a right frame side panel 122. The right frame front panel 121 extends along the up-down direction H and the left-right direction W, and the right frame side panel 122 extends backward along the front-back direction F from the left edge of the right frame front panel 121.

[0042] The left frame 13 has a symmetrical structure with the right frame 12. Figure 1a As shown, the left frame 13 has a left frame front panel 131 and a left frame side panel 132 .

[0043] When the elevator door frame 1 is in the installed state, the elevator door body is located between the right frame front panel 121 and the left frame front panel 131 .

[0044] Further, in this embodiment, the elevator door sleeve installation assembly includes two fasteners 2 ( Figure 1b Shown with Figure 1a The two fasteners 2 are respectively located at two sides of the elevator door opening in the left-right direction W and the structures of the two fasteners 2 are symmetrical about the center line of the elevator door opening in the left-right direction W, so that after the elevator door opening 1 is inserted into the elevator door opening, the two fasteners 2 are respectively assembled with the left frame 13 and the right frame 12 of the elevator door opening.

[0045] like Figure 1b to Figure 1e As shown, the fastener 2 includes a fastener side plate 21, a fastener fixing portion 22 connected to the fastener side plate 21, and a plurality of elastic pieces 21p provided on the fastener side plate 21. When the elevator door frame 1 is inserted into the elevator door frame installation assembly in the front-to-back direction F, the elevator door frame 1 presses against the elastic piece 21p, so that the elevator door frame 1 elastically abuts against the elastic piece 21p, so that the elevator door frame 1 is fixed relative to the elevator door frame installation assembly by means of the reaction force of the elastic piece 21p from the outside in the left-right direction W, so that the elevator door frame 1 can be fixedly installed at a predetermined position in the front-to-back direction F of the elevator door opening.

[0046] In this embodiment, if Figure 1b As shown, Figure 1a The fastener side plate 21 of the fastener 2 matched with the right frame 12 of the door cover assembly extends along the front-to-back direction F and the up-down direction H, and the fastener fixing portion 22 extends along the up-down direction H and the left-right direction W. The right edge of the fastener fixing portion 22 is connected to the rear edge of the fastener side plate 21. The fastener side plate 21 and the fastener fixing portion 22 can also be made of galvanized steel plates.

[0047] In this embodiment, if Figure 1b and Figure 1cAs shown, 12 elastic pieces 21p protrude from the flat fastener side plate 21 toward the inner side in the left-right direction W. The 12 elastic pieces 21p are arranged in the up-down direction H and the front-to-back direction F, and each elastic piece 21p is staggered in the front-to-back direction F and each elastic piece 21p is staggered in the up-to-down direction H, so that a plurality of elastic pieces 21p are arranged along a diagonal line of the fastener side plate 21. In this way, after the elevator door frame 1 is inserted into the elevator door frame installation assembly (elevator door opening) in the front-to-back direction F, as the elevator door frame 1 is inserted, the portion where the elastic piece 21p abuts against the right frame 12 has a reasonable distribution in both the up-down direction H and the front-to-back direction F. Compared with the case where each elastic piece 21p is not staggered in the front-to-back direction F or the up-to-down direction H, the distance between the elastic pieces 21p is fully guaranteed, and the situation where the portion between the elastic pieces 21p is narrow and the strength is difficult to guarantee can be avoided, thereby ensuring the firmness and accuracy of the elevator door frame 1 installed in the elevator door frame installation assembly.

[0048] Furthermore, if Figure 1b to Figure 1e As shown, for example, by stamping the fastener side plate 21, all the elastic pieces 21p can be formed at one time, so that the rear end edge of each elastic piece 21p in the front-to-rear direction F is tilted from the fastener side plate 21 toward the inner side in the left-right direction W. In this way, it can be ensured that the tilted shape of the elastic piece 21p will not interfere with the action of inserting the elevator door cover 1 into the elevator door cover installation assembly. Further, as Figure 1e As shown, the tilting angle α of the elastic sheet 21p relative to the fastener side plate 21 is greater than 0 degrees and less than 90 degrees. If the tilting angle α of the elastic sheet 21p exceeds 90 degrees, the elastic sheet 21p will interfere with the action of inserting the elevator door cover 1 into the elevator door cover installation assembly. Preferably, the tilting angle α of the elastic sheet 21p relative to the fastener side plate 21 is 40 degrees. Practice has proved that this can optimally take into account both not interfering with the action of inserting the elevator door cover 1 into the elevator door cover installation assembly and applying elastic force to the elevator door cover 1 through the elastic sheet 21p.

[0049] Furthermore, if Figure 1b As shown, the fastener fixing portion 22 is formed with three mounting holes 22h arranged in the up-down direction H. The fastener fixing portion 22 can be fixedly installed at an appropriate position of the wall of the elevator door opening by a fixing member passing through the three mounting holes 22h.

[0050] The basic structure of the elevator door cover assembly according to the first embodiment of the present invention is described above, and the basic structure of the elevator door cover assembly according to the second embodiment of the present invention will be described below.

[0051] (Elevator door cover assembly according to the second embodiment of the present invention)

[0052] The basic structure of the elevator door cover assembly according to the second embodiment of the present invention is substantially the same as the basic structure of the elevator door cover according to the first embodiment of the present invention, and only the difference between the two is described below.

[0053] Figure 2 FIG. 2 is a side view schematic diagram showing a fastener 2 of an elevator door cover mounting assembly of an elevator door cover assembly according to a second embodiment of the present invention. Figure 2 As shown, in the second embodiment, a plurality of elastic sheets 21p in the fastener 2 of the elevator door cover installation assembly are arranged in a rectangular array on the fastener side plate 21, and the array is an array in which the elastic sheets 21p are distributed in a 12×12 manner in the up-down direction H and the front-back direction F. In this way, the elastic force applied by the elastic sheets 21p of the elevator door cover installation assembly to the elevator door cover 1 can be greatly improved, thereby greatly improving the firmness of the installation of the elevator door cover 1 and the elevator door cover installation assembly to each other.

[0054] The basic structure of the elevator door cover assembly according to the second embodiment of the present invention is described above, and the basic structure of the elevator door cover assembly according to the third embodiment of the present invention will be described below.

Figure 3 As shown, in the third embodiment, a plurality of elastic pieces 21p in the fastener 2 of the elevator door cover mounting assembly are arranged in a regular pattern on the fastener side plate 21, wherein the regular pattern is a rhombus. Six elastic pieces 21p are arranged on each side of the rhombus. By arranging in this way, two elastic pieces 21p are arranged in each column in the up-down direction H and the front-back direction F.

[0058] In this way, compared with the first embodiment, the elastic force applied by the elastic sheet 21p of the elevator door cover installation assembly to the elevator door cover 1 can be greatly increased, thereby greatly improving the firmness of the installation between the elevator door cover 1 and the elevator door cover installation assembly. Compared with the second embodiment, the risk of greatly reducing the rigidity of the fastener side plate 21 due to stamping out too many elastic sheets 21p can be avoided.

[0061] The basic structure of the elevator door cover assembly according to the fourth embodiment of the present invention is substantially the same as the basic structure of the elevator door cover according to the first and second embodiments of the present invention, and only the differences therebetween are described below.

[0062] Figure 4 FIG. 2 is a side view schematic diagram showing a fastener 2 of an elevator door cover mounting assembly of an elevator door cover assembly according to a fourth embodiment of the present invention. Figure 4 As shown, in the fourth embodiment, a plurality of elastic pieces 21p in the fastener 2 of the elevator door cover mounting assembly are arranged in a horizontal "V" shape on the fastener side plate 21, that is, the plurality of elastic pieces 21p are arranged in a reciprocating manner in the front-to-back direction F when viewed from the up-down direction H. A total of 11 elastic pieces 21p are arranged in the "V" shape. By arranging in this way, each column arranged in the up-down direction H is arranged with one elastic piece 21p, and most of the columns arranged in the front-to-back direction F are arranged with two elastic pieces 21p.

[0063] In this way, compared with the first embodiment, the elastic force applied by the elastic sheet 21p of the elevator door cover installation assembly to the elevator door cover 1 can be ensured, thereby ensuring the firmness of the installation of the elevator door cover 1 and the elevator door cover installation assembly. Compared with the second embodiment, the risk of significantly reducing the rigidity of the fastener side plate 21 due to stamping out too many elastic sheets 21p can be avoided.

[0064] The basic structure of the elevator door cover assembly according to the fourth embodiment of the present invention has been described above, and the basic structure of the elevator door cover assembly according to the fifth embodiment of the present invention will be described below.

In this scheme, a total of 12 elastic pieces 21p are arranged. By arranging in this way, each row arranged in the up-down direction H is arranged with one elastic piece 21p, and each row arranged in the front-back direction F is arranged with two elastic pieces 21p.

[0068] In this way, compared with the first embodiment, the elastic force applied by the elastic piece 21p of the elevator door cover installation assembly to the elevator door cover 1 can be increased, thereby improving the firmness of the installation between the elevator door cover 1 and the elevator door cover installation assembly. Compared with the second embodiment, the risk of significantly reducing the rigidity of the fastener side plate 21 due to stamping out elastic pieces 21p with too narrow and dense intervals between each other can be avoided.

[0069] The basic structure of the elevator door cover assembly according to the fifth embodiment of the present invention has been described above, and the basic structure of the elevator door cover assembly according to the sixth embodiment of the present invention will be described below.

[0070] (Elevator door cover assembly according to the sixth embodiment of the present invention)

In this scheme, a total of 24 elastic pieces 21p are arranged. By arranging in this way, two elastic pieces 21p are arranged in each row in the up-down direction H and the front-back direction F.

[0073] In this way, compared with the first embodiment, the elastic force applied by the elastic sheet 21p of the elevator door cover installation assembly to the elevator door cover 1 can be greatly increased, thereby greatly improving the firmness of the installation between the elevator door cover 1 and the elevator door cover installation assembly. Compared with the second embodiment, the risk of greatly reducing the rigidity of the fastener side plate 21 due to stamping out too many elastic sheets 21p can be avoided.

[0075] (Elevator door cover assembly according to the seventh embodiment of the present invention)

[0076] The basic structure of the elevator door cover assembly according to the seventh embodiment of the present invention is substantially the same as the basic structure of the elevator door cover according to the first and second embodiments of the present invention, and only the differences therebetween are described below.

[0077] Figure 7 FIG. 2 is a side view schematically showing a fastener 2 of an elevator door cover mounting assembly of an elevator door cover assembly according to a seventh embodiment of the present invention. Figure 7 As shown, in the seventh embodiment, the fastener fixing portion 22 is formed integrally with the fastener side plate 21, that is, formed as a single plate-shaped portion. Three mounting holes 22h arranged in the up-down direction H are formed in the fastener fixing portion 22, and 12 elastic pieces 21p are formed on the fastener side plate 21. In addition, as long as the necessary mounting and fixing effect can be achieved, the setting method and setting position of the fastener fixing portion 22 can also be changed in various other ways.

[0079] (Elevator door cover assembly according to the eighth embodiment of the present invention)

[0080] The basic structure of the elevator door frame of the elevator door frame assembly according to the eighth embodiment of the present invention is the same as the basic structure of the elevator door frame of the elevator door frame assembly of the above embodiments, but the elevator door frame installation assembly of the elevator door frame assembly according to the eighth embodiment of the present invention includes a decorative part 3 in addition to the fastener 2.

[0081] Figure 8a is a perspective schematic diagram showing a decorative member of an elevator door cover assembly according to an eighth embodiment of the present invention; Figure 8b is a three-dimensional schematic diagram showing the installation of a fastener and a decorative member of an elevator door cover assembly in cooperation with each other according to an eighth embodiment of the present invention; Figure 8c It shows Figure 1a The right frame of the elevator door frame Figure 8b A top view of the elevator door after installation with the installation assembly. Figures 8a to 8c As shown, the decoration element 3 includes a decoration element side plate 31 , a decoration element fixing portion 32 , a front panel 33 and a folding portion 34 which are connected to each other.

[0082] In the present embodiment, the decorative part side panel 31 extends along the front-to-back direction F and the up-down direction H, the decorative part fixing portion 32 extends from the rear end edge of the decorative part side panel 31 along the left-right direction W toward the outer side of the left-right direction W, the front panel 33 extends from the front end edge of the decorative part side panel 31 toward the outer side of the left-right direction W, and the folding portion 34 extends from the outer end edge (right end edge) of the left-right direction W of the front panel 33 toward the rear.

[0083] The decoration fixing portion 32 of the decoration 3 is formed with a mounting hole (not shown) corresponding to the mounting hole 22h of the fastener fixing portion 22 of the fastener 2, so that the fastener 2 and the decoration 3 can be fixed to the wall of the elevator door opening together by the fixing member passing through the mounting holes matched with each other. In addition, by forming the mounting hole of the decoration fixing portion 32 of the decoration 3 into an oblong hole that is longer in the left-right direction W, the relative fixing position of the fastener 2 and the decoration 3 in the left-right direction can be adjusted, thereby adjusting the width of the installation space between the fastener side plate 21 of the fastener 2 and the decoration side plate 31 of the decoration 3 and adjusting the installation position of the elevator door frame 1 in the left-right direction W.

[0084] In addition, if Figure 8b As shown, the decorative member 3 may correspond to two fasteners 2, and the two fasteners 2 are arranged side by side in the up-down direction H, thereby improving the firmness and accuracy of the fixing of the elevator door frame 1 by the elevator door frame mounting assembly.

[0085] The above describes the specific structure of the elevator door cover assembly according to the present invention, and the assembly process of the elevator door cover assembly will be described below.

[0086] At the construction site, first, the fastener 2 and the decorative member 3 (if any) of the elevator door cover installation assembly are fixed to the appropriate position of the wall of the elevator door opening, so that the elevator door cover installation assembly is fixed relative to the wall of the elevator door opening and the fastener side plate 21 of the fastener 2 of the elevator door cover installation assembly is roughly parallel to the side wall of the elevator door opening. Subsequently, the elevator door cover 1 is inserted into the elevator door cover installation assembly along the front-to-back direction F, so that the right frame side plate 122 of the right frame 12 of the elevator door cover 1 and / or the left frame side plate 132 of the left frame 13 are opposite to the fastener side plate 21 of the fastener 2 of the elevator door cover installation assembly. In this way, the elevator door cover 1 presses against the elastic sheet 21p, so that the elevator door cover 1 is fixed relative to the elevator door cover installation assembly by means of the reaction force of the elastic sheet 21p from the outside in the left-right direction W, so that the elevator door cover 1 can be fixedly installed at the predetermined position of the elevator door opening. Obviously, the above assembly method is simple and convenient, and the assembled structure is firm and has high positioning accuracy.

[0087] Although the specific embodiments of the present invention have been described in detail in the above content, the following contents still need to be explained.

[0088] i. Although the elastic piece 21p is formed by stamping the fastener side plate 21 of the fastener 2 in the above specific embodiment, the present invention is not limited thereto. The elastic piece 21p can also be formed by other methods such as adding. Moreover, the shape of the elastic piece 21p is not limited to the shape shown in the figure, and the material is not limited to the same as the fastener side plate 21.

[0089] ii. Although the above specific embodiments only describe various arrangements of the elastic sheets 21p, the present invention is not limited thereto and different arrangements can be used as required. Preferably, at least one elastic sheet 21p should be provided in each column in the up-down direction H and the front-back direction F.

[0090] iii. The number of fasteners 2 of an elevator door installation assembly is not limited to that described in the above specific implementation manner, but can be increased or decreased as needed.

[0091] iv. In order to ensure that the elastic sheet 21p has a one-way non-return structure that only allows the elevator door frame 1 to move toward the direction close to the elevator door frame when it is elastically abutted against the elevator door frame 1, the elastic sheet 21p can be appropriately tilted at an angle (for example, between 65 and 80 degrees) or each elastic sheet 21p can be formed into a curved shape that is convex forward in the front-to-back direction F.

[0092] v. Although the elastic sheet 21p described in the above specific embodiment is punched from the fastener fixing part 22, and the two are fixed to each other, the present invention is not limited thereto. The elastic sheet 21p can be mounted on the fastener fixing part 22, for example, by a component including a hinge and a spring, so that the two are not fixed to each other.

[0093] Even in the present invention, the elastic abutting portion and the fastener fixing portion are not directly connected, that is, the two can be separated.

[0094] In addition, it should be noted that the protection scope of the present invention is not limited to the specific embodiments described in the above specific implementation modes, and those skilled in the art can make various reasonable modifications and feature combinations to the technical solutions of the present invention within the scope of the present invention.
