Description

Technical Field

[0001] The present invention relates to the technical field of escalators, and more particularly to steps for escalators. Background Art

[0002] Escalators are widely used in public places such as shopping malls, train stations, and subways. The steps installed on an escalator primarily consist of a tread, a riser plate suspended downward from the rear end of the tread, and support plates connecting the tread and riser. For example, a step made of aluminum alloy has a breaking load of 20 kN. However, in some cases, a breaking load exceeding 30 kN is required.

[0003] For this reason, a step of an escalator with a higher breaking load is required. Summary of the Invention

[0004] One object of the present invention is to provide an escalator step that can increase the breaking load of the step. Another object of the present invention is to provide an escalator step that can be flexibly reinforced, for example, by increasing the breaking load and Young's modulus of the step and ribs and reducing deformation. Another object of the present invention is to provide an escalator step that can be cost-effectively reinforced.

[0005] One aspect of the present invention provides a step of an escalator, comprising: a footrest body including a pedal and a kick plate, the pedal and the kick plate being connected to form an L-shaped cross-section; two shaft mounting portions, respectively provided at both ends of the step in the width direction; a rib extending between the two shaft mounting portions in the width direction of the step, wherein, when viewed in the width direction, the rib extends from the pedal to the shaft mounting portion, and the upper end of the rib is connected to the pedal; and a reinforcement portion, provided at the lower end of the rib away from the pedal to provide an increased area at the lower end of the rib. The reinforcement portion can provide an increased area at the lower end of the rib, which can increase the breaking load and Young's modulus of the rib and the step, for example, a breaking load higher than 30 kN. In addition, the breaking load of the step can be advantageously increased without significantly increasing the cost.

[0006] According to an embodiment of the present invention, the rib extends obliquely from the tread plate in a direction away from the riser plate when viewed in the width direction. In the case where the rib can increase the breaking load of the step, the reinforcement can further increase the breaking load of the step.

[0007] According to an embodiment of the present invention, the reinforcement is integrally formed with the rib. By adding additional material to the lower end of the rib to form the reinforcement integrally, pores and cracks caused by the accumulation of a large amount of material in the rib can be avoided or reduced, thereby improving the breaking load and Young's modulus of the rib and the step.

[0008] According to an embodiment of the present invention, the reinforcement portion extends from the rib plate in a direction away from the riser plate.

[0009] According to an embodiment of the present invention, the reinforcement at least partially surrounds the lower end of the rib. The reinforcement can provide an increased area at the lower end of the rib, which can increase the breaking load and Young's modulus of the rib and the step.

[0010] According to an embodiment of the present invention, the reinforcement is formed separately from the rib. By providing an independent reinforcement at the lower end of the rib, an increased area can be flexibly provided at the lower end of the rib, thereby cost-effectively increasing the breaking load of the rib and the step.

[0011] According to an embodiment of the present invention, the step further includes a pivot located at an end of the riser plate away from the tread, and the reinforcement further includes a foot extending toward the pivot. In this case, the overall height of the rib and reinforcement is increased, and a larger area of increased surface is provided at the lower end of the rib, thereby enabling the rib and the step to have a higher breaking load.

[0012] According to an embodiment of the present invention, the reinforcement part is detachably connected to the rib plate, thereby enabling the reinforcement part to be connected more flexibly.

[0013] According to an embodiment of the present invention, the reinforcement part is made of metal. Metal (such as steel or aluminum alloy) has a high yield strength and a high Young's modulus, and thus can provide a high breaking load and a small deformation.

[0014] Another aspect of the present invention provides an escalator comprising steps according to an embodiment of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Hereinafter, embodiments of the present invention are described with reference to the accompanying drawings. The following detailed description and the accompanying drawings are used to illustrate the principles of the present invention by way of example. The present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims. The present invention will now be described in detail with reference to exemplary embodiments, some of which are illustrated in the accompanying drawings. The following description is made with reference to the accompanying drawings, and unless otherwise indicated, the same reference numerals in different drawings represent the same or similar elements. The schemes described in the following exemplary embodiments do not represent all schemes of the present invention. On the contrary, these schemes are merely examples of systems and methods of various aspects of the present invention involved in the appended claims.

[0020] Figure 1 is a cutaway perspective view of steps of an escalator according to certain embodiments. Figure 2 is a side view of a step of an escalator according to some embodiments of the present invention. Figure 3 is a cutaway perspective view of steps of an escalator according to some embodiments of the present invention. Figure 4 is a side view of an escalator step according to some embodiments of the present invention. The step according to the present invention can be installed in an escalator, such as an escalator used in a subway.

[0021] like Figures 1 to 4 As shown, the steps of an escalator according to certain embodiments of the present invention include a pedal 1, a kick plate 2 and a shaft mounting portion 3. In some embodiments, the pedal 1 includes ribs located on the upper surface for, for example, anti-slip purposes. The kick plate 2 is directly connected to the pedal 1 at one end (the upper end of the kick plate 2). When viewed from the side, the pedal 1 and the kick plate 2 are connected to form an L-shaped cross section. According to certain embodiments of the present invention, the kick plate 2 includes a shaft 21 located at the end of the kick plate 2 away from the pedal 1.

[0022] In the exemplary embodiment, the step includes two shaft mounting portions 3 ( Figure 1 and Figure 4 Only one is shown in the figure), which are respectively arranged at both ends of the step in the width direction, that is, arranged on both sides of the pedal 1 and the kick plate 2 in the width direction.

[0023] According to some embodiments of the present invention, the steps may further include ribs 4 and reinforcements 5. The ribs 4 are disposed below the kick plate 1. In an exemplary embodiment, the ribs 4 extend from the tread 1 to the shaft mounting portion 3 when viewed in the width direction, for example, the upper end of the ribs 4 is connected to the tread 1. In some embodiments, the ribs 4 are arranged between two shaft mounting portions 3 along the width direction. In some embodiments, the ribs 4 extend from the tread 1 toward the shaft mounting portion 3. In some embodiments, when viewed from the side view, the ribs 4 extend obliquely relative to the tread 1, that is, they extend obliquely from the tread 1 in a direction away from the kick plate 2. The ribs 4 can increase the breaking load of the steps.

[0024] According to some embodiments of the present invention, a reinforcement portion 5 is provided at an end (lower end) of the rib 4 away from the tread 1. The reinforcement portion 5 is used to further increase the breaking load of the step.

[0025] According to some embodiments of the present invention, Figure 2 As shown, the reinforcement 5 is a material addition portion provided at the lower end of the rib 4. In this case, the reinforcement 5 and the rib 4 are formed integrally. The reinforcement 5 is formed by adding additional material to the lower end of the rib 4. In an exemplary embodiment, the reinforcement 5 is made of aluminum alloy. In some embodiments, as Figure 2 As shown, the reinforcement 5 extends from the rib 4 in a direction away from the riser 2 .

[0026] By adding extra material at the lower end of the rib 4, pores and cracks caused by a large amount of material accumulation in the rib 4 can be avoided or reduced. The reinforcement 5 provides an increased area at the lower end of the rib 4, which can increase the breaking load of the rib 4 and the step.

[0027] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the reinforcement 5 is provided to at least partially surround the lower end of the rib 4. In this case, the reinforcement 5 and the rib 4 are formed separately. In some embodiments, the reinforcement 5 is detachably connected to the rib 4. In an exemplary embodiment, the reinforcement 5 is clamped onto the rib 4, as shown in FIG. Figure 3 As shown. In other embodiments, the reinforcement 5 can also be connected to the rib 4 by screws, rivets, adhesives, etc. In the exemplary embodiment, the reinforcement 5 is made of steel. Steel has a high yield strength and a high Young's modulus, thus providing a high breaking load and low deformation. By providing a separate reinforcement 5 at the lower end of the rib 4, an increased area is provided at the lower end of the rib 4, thereby increasing the breaking load of the rib 4 and the step.

[0028] In some embodiments, the reinforcement 5 further includes a foot 51 extending toward the rotation axis 21. In this case, the overall height of the rib 4 and the reinforcement 5 is increased, and a larger area of increased area is provided at the lower end of the rib 4. As a result, the rib 4 and the step can have a higher breaking load.

[0029] According to some embodiments of the present invention, Figure 4 As shown, the rib plate 4 may further include a reinforcement frame 41 near the tread 1. The reinforcement frame 41 may include an opening, such as a triangular opening. According to some embodiments of the present invention, the step may further include one or more supporting ribs 42 connecting the lower surface of the tread 1 and the inner surface of the kick plate 2.

[0030] In some embodiments, the steps may further include a bracket 6. Bracket 6 connects the shaft mounting portion 3 and the shaft 21. In some embodiments, bracket 6 connects from one end of the tread 1 (the end away from the connection between the tread 1 and the kick plate 2) to one end of the kick plate 2 (the lower end of the kick plate 2). In an exemplary embodiment, bracket 6 is made of metal, such as aluminum alloy, steel, etc. In some embodiments, the steps may not include the bracket 6 connected between the shaft mounting portion 3 and the shaft 21.

[0031] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the configurations and methods of the above-described embodiments. On the contrary, the present invention is intended to cover various modifications and equivalent configurations. In addition, although the various elements and method steps of the disclosed invention are shown in various exemplary combinations and configurations, other combinations including more or fewer elements or methods also fall within the scope of the present invention.
