[0048] In order to make the purpose, scheme and advantages of the technical solution of the present invention more clear, the following will be combined with the drawings of specific embodiments of the present invention to clearly and completely describe the technical solution of the present invention. Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0049] Figure 1A schematic diagram of a handrail assembly 1 according to an embodiment of the present invention is shown. The handrail assembly 1 can be used for an escalator to prevent users from falling from the escalator. The handrail assembly 1 mainly includes a panel 10, a panel holder 20, an inner cover plate 30, an outer cover plate 40 and a clamping member 100. The panel 10 has a plate-like shape, and the panel 10 is arranged on both sides of the escalator to prevent users from falling from the escalator. For example, the panel 10 can be a transparent glass plate. The panel holder 20 is configured to fix one end of the panel 10, for example, the lower end of the panel 10. The inner cover plate 30 is arranged on the inner side of the width direction of the escalator relative to the panel 10, and the outer cover plate 40 is arranged on the outer side of the width direction of the escalator relative to the panel 10.

[0050] like Figure 2 As shown, the clamping member 100 includes a first supporting portion 110, a second supporting portion 120, and a clamping portion 130. The first supporting portion 110 and the second supporting portion 120 are respectively configured to support and clamp the inner cover plate 30 and the outer cover plate 40. The clamping portion 130 is disposed between the panel 10 and the panel retainer 20 to clamp a portion of the panel 10. To facilitate assembly of the railing assembly 1, the clamping member 100 is integrally formed. In other words, the first supporting portion 110, the second supporting portion 120, and the clamping portion 130 are collectively formed as a single component of the clamping member 100. Furthermore, compared to a case where the clamping portion and the supporting portion are formed as separate components, the integrally formed clamping member 100 exhibits high toughness, high impact strength, and low-temperature resistance.

[0051] Specifically, the clamping portion 130 may have a U-shape and at least partially surround a receiving space, into which a portion of the panel 10 is inserted. Figure 1 As shown, during the assembly of the railing assembly 1 , the panel 10 is first inserted into the gap between the first support portion 110 and the second support portion 120 from top to bottom, and then inserted into the accommodation space formed by the clamping portion 130 .

[0052] Specifically, the first support portion 110 may include a first upper arm 112 and a first lower arm 114. One end of the first upper arm 112 (eg, Figure 2 The right end shown in FIG) and one end of the first lower arm 114 (for example, Figure 2 The second support portion 120 may include a second upper arm 122 and a second lower arm 124, one end of the second upper arm 122 (e.g., as shown in FIG. Figure 2 The left end shown in FIG) and one end of the second lower arm 124 (eg, Figure 2The left end of the outer cover plate 40 is connected to form a second groove 126, and a portion of the outer cover plate 40 is clamped in the second groove 126. In addition, the connection portion between the first lower arm 114 and the first upper arm 112 can be adjacent to the open end of the clamping portion 130 near the first support portion 110, and the connection portion between the second lower arm 124 and the second upper arm 122 can be adjacent to the open end of the clamping portion 130 near the second support portion 120.

[0053] Preferably, the first support portion 110 may further include a first tip 118 extending from the corresponding connection portion back toward the first upper arm 112, and the second support portion 120 may further include a second tip 128 extending from the corresponding connection portion back toward the second upper arm 122, with the panel 10 being sandwiched between the first tip 118 and the second tip 128. Figure 1 As shown, during assembly of the railing assembly 1, the panel 10 is first inserted into the gap between the first tip 118 and the second tip 128 from top to bottom, and then inserted into the receiving space formed by the clamping portion 130. The first tip 118 and the second tip 128 can be used to seal the receiving space together with the panel 10 to prevent foreign matter from entering the receiving space.

[0054] Preferably, the hardness of the first tip 118 of the first support portion 110 can be less than the hardness of the clamping portion 130, the first upper arm 112 of the first support portion 110, and the first lower arm 114. The hardness of the second tip 128 of the second support portion 120 can be less than the hardness of the clamping portion 130, the second upper arm 122, and the second lower arm 124 of the second support portion 120. The lower hardness of the first and second tips 118, 128 facilitates the insertion of the panel 10 into the accommodation space formed by the clamping portion 130 through the gap formed between the first and second tips 118, 128, while the higher hardness of the clamping portion 130 facilitates the clamping and securing of the panel 10 by the clamping portion 130. Furthermore, the higher hardness of the first upper arm 112 and the first lower arm 114 facilitates their support for the inner cover 30, while the higher hardness of the second upper arm 122 and the second lower arm 124 facilitates their support for the outer cover 40.

[0055] Preferably, the first and second tips 118, 128 can be made of acrylonitrile butadiene rubber (ABS) or polystyrene. The clamping portion 130, the first upper arm 112, the first lower arm 114, the second upper arm 122, and the second lower arm 124 can be made of polypropylene. Using a non-metallic material to construct the clamping member 100 reduces the weight of the railing assembly 1, lowering carbon emissions and material costs.

[0056] Preferably, the clamp 100 can be manufactured using an extrusion process. The extrusion process allows different portions of the clamp 100 to have different hardnesses (as described above, the first tip 118 and the second tip 128 are relatively soft, while other portions are relatively hard) while the clamp 100 is integrally formed, thereby meeting corresponding functional requirements.

[0057] This document describes in detail several exemplary embodiments of the present invention with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and the various technical features and structures proposed in the present invention may also be combined without exceeding the scope of protection of the present invention, which is determined by the appended claims.
