Description

Technical Field

[0001] This invention relates to the field of escalator technology, specifically to an escalator skirt panel and an escalator. Background Technology

[0002] Due to their structural characteristics, escalators have both moving and stationary parts. When transporting passengers, they move with the steps, but the skirt panels on both sides of the steps remain stationary. This relative motion creates a risk that passengers' shoes may become trapped in the gap between the steps and the skirt panels when they come into contact with the skirt panels under pressure. This is especially true when wearing soft shoes, which could further cause foot compression.

[0003] To reduce risks and improve escalator safety, standards such as GB16899 have set forth several requirements. These include the installation of anti-pinch devices on escalators' skirt panels. These devices consist of a rigid base and flexible brushes or rubber at the upper edge of the skirt panel, and the specified dimensions of the device protruding from the skirt panel. The aim is to keep passengers away from the relative movement area between the steps and the skirt panel. GB16899 also specifies the coefficient of sliding friction between footwear and the skirt panel surface to reduce sliding friction and minimize the risk of pinching.

[0004] These measures have significantly reduced the occurrence of incidents where aprons are pinched between the apron board and the ladder steps, but accidents still occasionally appear in the news. Furthermore, these measures have not fundamentally solved the problem of preventing apron boards from pinching. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to provide an escalator skirt board with anti-pinch function.

[0006] To solve the above-mentioned technical problems, the present invention provides an escalator skirt board, wherein the outer surface of the skirt board has a raised sloping front slope and a sloping back slope; the intersection of the sloping front slope or the sloping back slope and the running surface of the steps makes an angle β1 with the horizontal plane, wherein the angle β1 satisfies α≤β1<90°, and α is the angle between the running direction of the steps and the horizontal plane.

[0007] Preferably, the slope and back slope of the inclined plane are located near the left and right sides of the adjacent steps.

[0008] Preferably, the front slope and the back slope of the inclined plane extend through the entire apron panel.

[0009] Preferably, the angle α between the running direction of the ladder and the horizontal plane is between 0 and α. inc Variation within the range, α inc The angle of inclination of the escalator.

[0010] Preferably, the complementary angle θ between the slope of the inclined plane and the running surface of the steps satisfies θ≤acos(μtanβ1).

[0011] The present invention also provides an escalator skirt board, wherein the outer surface of the skirt board has a raised sloping front slope and a sloping back slope; the tangent of the intersection line of the sloping front slope or the sloping back slope and the running surface of the steps makes an angle β2 with the horizontal plane, wherein the angle β2 satisfies α≤β2, and α is the angle between the running direction of the steps and the horizontal plane.

[0012] The present invention also provides an escalator, including the aforementioned escalator skirt panel, wherein the skirt panel is installed in the inclined section, the upper curved transition section or the lower curved transition section of the escalator. Attached Figure Description

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can fully understand other advantages and technical effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through different specific embodiments, and the details in this specification can also be applied based on different viewpoints, with various modifications or changes made without departing from the overall design concept of the invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited to the specific embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the technical solutions of these exemplary embodiments to those skilled in the art.

[0021] The causes of the risk of being pinched by the skirt board on escalators are analyzed as follows:

[0022] like Figure 1As shown, for a descending escalator, the steps move obliquely downward relative to the fixed skirt board. When shoes or other items on the step surface scrape against the skirt board, the skirt board provides the shoes with an oblique upward frictional force opposite to the direction of the step's movement. Under the action of friction, the shoes deform away from the gap between the side of the step and the skirt board, thus preventing the risk of shoes or other items getting squeezed into the gap between the side of the step and the skirt board.

[0023] like Figure 2 As shown, for an upward-moving escalator, the steps run obliquely upward relative to the fixed skirt board; when shoes or other items on the step surface scrape against the skirt board, the skirt board provides the shoes with a downward-sloping frictional force; under the action of friction, the shoes deform towards the gap between the side of the step and the skirt board; this deformation increases the squeezing force between the shoes and the skirt board, further aggravating the squeezing of the shoes.

[0024] Example 1

[0025] like Figure 3 As shown, this embodiment provides an escalator skirt panel. The outer surface of the skirt panel has a raised sloping front slope and a sloping back slope. The angle between the intersection of the sloping front slope or the sloping back slope and the running surface of the steps and the horizontal plane is β1, and the angle β1 satisfies α≤β1<90°, where α is the angle between the running direction of the steps and the horizontal plane. The angle α between the running direction of the steps and the horizontal plane is between 0 and α... inc Variation within the range, α inc The angle of inclination of the escalator.

[0026] like Figure 5 As shown, the passenger-carrying section of an escalator consists of an upper horizontal section, an upper curved transition section, an inclined section, a lower curved transition section, and a lower horizontal section; for an inclined angle of α... inc The escalator has steps that run horizontally in the upper and lower horizontal sections, while the steps in the inclined sections are inclined at an angle α to the horizontal plane. inc During operation, the upper and lower curved transition sections connect the upper and lower horizontal sections to the inclined section via circular arcs.

[0027] Generally, the inclination angle α of an escalator inc ≤35°, preferably 35°, 30°, 27.3° and 23.2°; the angle α between the running direction of the escalator steps and the horizontal plane in different passenger-carrying sections is between 0 and α. inc Variations within the range.

[0028] In this embodiment, the skirt panel is installed in the inclined section of the escalator. In one approach, the front and back slopes can extend through the entire skirt panel, facilitating direct bending processing. In another approach, the front and back slopes can be positioned near the left and right sides of the adjacent steps, in areas where passengers' shoes are likely to brush against them; in this case, the slopes do not need to extend through the entire skirt panel, and the joints between the skirt panel and other components are flat.

[0029] As the escalator ascends and shoes scrape against the raised, sloping back of the skirt board, the gap between the side of the step and the sloping back of the skirt board gradually increases as the steps move upwards at an angle, preventing shoes from getting stuck in the gap between the side of the step and the skirt board.

[0030] When the escalator ascends and shoes scrape against the sloping side of the skirt board, the shoes experience a normal force N from the sloping side and a frictional resistance f = μN; according to force analysis, μ is the coefficient of friction. When the slope between the escalator and the running plane satisfies μNtanβ1≤Ncosθ, that is, the complementary angle θ between the sloping side and the running plane satisfies θ≤acos(μtanβ1), the vertical component of the resultant force on the shoes from the skirt board is upward. This prevents the shoes from scraping against the slope and causes them to be squeezed into the gap between the side of the step and the skirt board.

[0031] The footwear is elastic. When the footwear scrapes against the apron board, the larger the gap between the side of the step and the apron board, the easier it is for the footwear to undergo elastic deformation and thus get squeezed into the gap. The protrusions on the apron board enhance its rigidity, reduce the deformation of the apron board when the footwear scrapes against it, prevent the gap between the side of the step and the apron board from widening, and reduce the risk of the footwear getting squeezed.

[0032] In addition, the raised, serrated protrusions on the apron board serve as a visual warning of risks, keeping passengers away from dangerous areas and reducing the risk of scratches caused by contact.

[0033] Example 2

[0034] like Figure 4 As shown, this embodiment provides an escalator skirt board, the outer surface of which has a raised sloping front slope and a sloping back slope; the tangent of the intersection line of the sloping front slope or the sloping back slope and the running surface of the steps makes an angle β2 with the horizontal plane, the angle β2 satisfying α≤β2, where α is the angle between the running direction of the steps and the horizontal plane.

[0035] In this embodiment, the skirt panel is installed in the upper or lower curved transition section of the escalator. In this embodiment, the raised front slope and back slope of the escalator are curved when viewed from the front of the skirt panel, while in Embodiment 1, the front slope and back slope of the skirt panel installed in the inclined section of the escalator are straight when viewed from the front of the skirt panel.

[0036] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
