Abstract
Description
Technical Field
[0001] This invention relates to the field of escalator technology, and more specifically to an escalator with a slender handrail featuring an end reinforcement structure. Background Technology
[0002] With the continuous development of modern architectural design, slender escalators have gradually become a new favorite in the market due to their advantages such as simple structure, smooth lines, and high space utilization. These escalators usually adopt a glass handrail design, with only a guide rail for guidance below the handrail. The center of the glass handrail and the guide rail are on the same straight line. The guide rail is a pre-made part, and there are elastic glass clamps below it. The glass handrail is fixed by the elasticity of the glass clamps. The overall structure is simple and clear.
[0003] While slender escalators are well-suited for commercial spaces with ceiling heights less than 6 meters, they present numerous technical challenges for spaces with ceiling heights greater than 6 meters or even 10 meters. These challenges result in difficulties in utilizing them effectively. For instance, insufficient strength at the ends of the escalator can lead to increased vibration or even breakage of the glass handrail panels during operation. Furthermore, the increased stress on the slewing chain and rollers at the ends of the escalator results in a shorter lifespan, often requiring replacement every 1-2 years. Summary of the Invention
[0004] The purpose of this invention is to address the deficiencies and shortcomings of the prior art by providing a reasonably designed escalator with a slender handrail featuring an end reinforcement structure, which can solve the aforementioned defects.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes end-reinforced handrails located at the upper and lower ends of an escalator, and slender handrails located on the upper and lower arc sections and inclined sections of the escalator handrails. The slender handrails include slender handrail guide rails, and the end-reinforced handrails include end-reinforced rotating handrail guide rails. The end-reinforced rotating handrail guide rails are provided with end-rotating sprocket assemblies, which include end-rotating chains and multiple rollers. The end-reinforced rotating handrail guide rails and the slender handrail guide rails are connected by variable cross-section handrail guide rails.
[0006] Preferably, the slender handrail guide rail, the variable cross-section handrail guide rail, and the end-reinforced swivel handrail guide rail are all provided with annular handrail belts, and elastic glass clamps are provided below the guide rails, with the handrail panels of the escalator clamped in the elastic glass clamps.
[0007] Preferably, the center lines of the slim handrail guide rail, the variable cross-section handrail guide rail, the end-reinforced swivel handrail guide rail, and the handrail panel are aligned.
[0008] Preferably, the variable cross-section handrail guide rail includes a handrail inclined guide rail, and a handrail guide rail wing plate is installed upward on the inner side of the handrail inclined guide rail via a support column. The two ends of the support column are respectively installed by flat base screws.
[0009] Preferably, both ends of the variable cross-section handrail are connected to the slim handrail and the end-reinforced swivel handrail via handrail connecting brackets.
[0010] Preferably, both ends of the end slewing sprocket assembly are connected to the end reinforced slewing handrail guide rail via screw hooks. A fixed bend plate is installed inside the end reinforced slewing handrail guide rail via flat base rivets, and the screw hook is installed in the fixed bend plate via adjusting nuts.
[0011] Preferably, the handrail is an integral handrail with a thickness of not less than 10mm, which is a tempered glass plate or a stainless steel composite plate.
[0012] The beneficial effects of the present invention after adopting the above structure are: 1. This application solves the problem of low end structural strength of slender escalators, which cannot be applied to commercial spaces with high floor heights, by designing the height of the end-reinforced handrail guide rail.
[0013] 2. This application extends the service life of the end handrail by enlarging the slewing chain and rollers of the end handrail.
[0014] 3. The end-reinforced handrail guide rail of this application adopts a design that is aligned with the glass handrail panel. Compared with the traditional thickened handrail escalator, the overall width is reduced by 60mm. At the same time, this invention retains the advantages of high space utilization and aesthetics of the slim handrail escalator. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] See Figures 1-10 As shown, it includes end-reinforced handrails located at both the top and bottom of the escalator, i.e., attached... Figure 1 The middle β section, and the slender handrails located on the upper and lower arc sections and inclined sections of the escalator handrail, i.e., attached Figure 1 In the middle α section, the slender handrail includes a slender handrail guide rail 3, and the end-reinforced handrail includes an end-reinforced rotating handrail guide rail 10. The end-reinforced rotating handrail guide rail 10 is provided with an end-rotating sprocket assembly 11, which includes an end-rotating chain and multiple rollers. All rollers are large-diameter bearing rollers 19. The end-reinforced rotating handrail guide rail 10 and the slender handrail guide rail 3 are connected by a variable cross-section handrail guide rail 5. The slender handrail guide rail 3, the variable cross-section handrail guide rail 5, and the end-reinforced swivel handrail guide rail 10 are all equipped with annular handrail belts 4, and elastic glass clips 2 are provided below the guide rails. The handrail panels 1 of the escalator are all clamped in the elastic glass clips 2. The center lines of the slender handrail guide rail 3, the variable cross-section handrail guide rail 5, the end-reinforced swivel handrail guide rail 10, and the handrail panels 1 are aligned. The variable cross-section handrail guide rail 5 includes a handrail inclined guide rail 7. The handrail inclined guide rail 7 has a handrail guide rail wing plate 9 installed upward through a support column 6 on the inner side. The two ends of the support column 6 are respectively installed by flat base screws 8. Both ends of the variable cross-section handrail guide rail 5 are connected to the slim handrail guide rail 3 and the end-reinforced rotary handrail guide rail 10 through the handrail guide rail connecting bracket 17; Both ends of the end slewing sprocket assembly 11 are connected to the end reinforced slewing handrail guide 10 via screw hooks 13. The end reinforced slewing handrail guide 10 is fitted with a fixed bend plate 14 via flat base rivets 16.

It is made of tempered glass or stainless steel composite plate, so the connection accuracy can be guaranteed without the need for adjustment mechanism. The rollers are fixed in an integral manner by a rotary chain, which is simple to assemble and does not require repeated debugging and installation.
[0019] like Figure 7 Traditional slender handrails use small-diameter bearing rollers 20 at their ends, resulting in poor load-bearing capacity; while... Figure 8 The thickened handrails used in traditional high-rise escalators employ offset installation of the thickened handrail guide rail 18, resulting in an increased overall width of the handrail compared to the slender handrail. This application utilizes large-diameter bearing rollers 19 at the ends, along with a matching slewing chain, significantly extending the lifespan of the handrail. Furthermore, the entire escalator is centrally installed, eliminating the need to increase its overall width compared to... Figure 8 Compared to traditional equipment, the escalator width is reduced by 60mm, achieving the advantages of a slim handrail escalator—high utilization rate and good aesthetics—while occupying less space.
