Elevator car lining panels according to exemplary embodiments of the invention may be installed fast and easily by joining corresponding connection portions of adjacent elevator car lining panels and fixing the first connection portion of the elevator car lining panel to a corresponding (adjacent) structural panel of the elevator car. This allows for installing the elevator car lining panels much faster and easier than conventional methods.
Exemplary embodiments of the invention are described in more detail with respect to the enclosed figures.
The elevator car 2 comprises a plurality of structural panels 41-49 forming in combination with a front panel 5 an outer frame of the elevator car 2. The outer frame of the elevator car 2 includes a rear wall 9 and two opposing side walls 6, 7 defining an interior space 3 of the elevator car 2 for accommodating the passengers. The front panel 5 is configured for supporting at least one door (not shown) providing access to the interior space 3 of the elevator car 2.
In a first step, a first elevator car lining panel 81 is arranged inside the interior space 3 next to a first structural panel 41. The first elevator car lining panel 81 may be formed from an extruded sheet, in particular a plastic sheet or a metal sheet, which in particular may include aluminum. The sheet may be laminated with a cover layer on one or both sides. Particularly, the inner side may be laminated by a decor layer.
At the end facing the front panel 5 the first elevator car lining panel 81 comprises a first arcuate edge portion 30. The area of a front corner 37 formed by the front panel 5 and the adjacent first structural panel 41 is shown in an enlarged view in
A receiving portion 26 is provided at an end of the first arcuate edge portion 30 facing away from the first structural panel 41 in a direction parallel to the front panel 5. Said receiving portion 26, which may be formed by bending the sheet material of the first elevator car lining panel 81, in particular is configured for accommodating at least one lighting element 22.
In the configuration shown in the figures, the sheet material of the first elevator car lining panel 81 is bend further in order to provide a supporting section 28 located between the first arcuate edge portion 30 and the adjacent first structural panel 41. The supporting section 28 supports and strengthens the first elevator car lining panel 81 in particular in an area next to the first arcuate edge portion 30.
At least one lighting element 22, which is configured for illuminating the interior of the elevator car 2, extends along the height of the first elevator car lining panel 81. The at least one lighting element 22 may comprise at least one of a neon tube, a fluorescent lamp and one or more LEDs, which provide a convenient and efficient light source. The light source(s) are covered by a cover element 24. The cover element 24 may be configured for mechanically protecting the light source(s) from being damaged. Additionally and/or alternatively the cover element 24 may be configured for distributing the light provided by the light source(s) of the at least one lighting element 22 in order to achieve a convenient illumination of the interior space 3 of the elevator car 2.
A first connection portion 10 is provided at an opposing side of the first elevator car lining panel 81 facing the rear wall 9. An enlarged view of said area is shown in
The first connection portion 10 comprises an arcuate portion 12 providing an open side facing the rear wall 9, and a straight portion 14 extending basically parallel to the planes of the first elevator car lining panel 81 and the adjacent first structural panel 41.
A first connection portion 10 having such a configuration may be formed e.g. by extruding the first elevator car lining panel 81 through an appropriate extrusion mask or by bending an originally flat sheet of material.
At least one opening 20, in particular a circular opening 20, is provided in the straight portion 14 of first connection portion 10. Such an opening 20 allows a fixing element 16, e.g. a bolt, a screw or a rivet, which is not shown in
Said second connection portion 18 in particular includes a clipping mechanism 19 which is constituted by two elastic clipping arms 19a, 19b facing the first connection portion 10 of the adjacent first elevator car lining panel 81. The elastic clipping arms 19a, 19b are configured to elastically deform when entering into the open side of the arcuate portion 12 of the first connection portion 10. The elastic clipping arms 19a, 19b then clamp inside said arcuate portion 12 by resuming their original configuration providing a secure connection between the first and second elevator car lining panels 81, 82.
In said connected configuration, the fixing elements 16 passing through the openings 20 provided in the first connection portion 10 are neither visible nor accessible, as they are covered by the second elevator car lining panel 82. This prevents passengers residing in the interior space 3 of the elevator car 2 from being injured or their clothing being damaged from contacting the fixing elements 16. Covering the fixing elements 16 further prohibits an unauthorized removal of the fixing elements 16 by passengers and provides an aesthetic configuration of the elevator car's interior space 3.
Another first connection portion 10 is provided at the right side of the second car lining panel 82, which is not shown in
An exemplary sequence of installing a plurality of car lining panels 81, 82, 83 inside an elevator car 2 is illustrated in the following figures:

Additionally, the first connection portion 10 of the second car lining panel 82 is fixed to an adjacent third structural panel 43 by means of fixing elements 16 passing through the openings 20 provided in the first connection portion 10 of the second car lining panel 82 and the adjacent third structural panel 43.
Finally,
Said third elevator car lining panel 83 comprises a second arcuate edge portion 32 having a similar but mirrored configuration as the first arcuate edge portion 30 of the first elevator car lining panel 81. Said second arcuate edge portion 32 is arranged in the corner 37 formed by the side wall 6 and the rear wall 9 of the elevator car 2, which is formed by the third and a fourth structural panels 43, 44.
As a result, in a configuration as it is shown in
As depicted in
The extension (width) of the third elevator car lining panel 83 in a direction parallel to the plane defined by the structural panels 4a-4c of the side wall 6, is set so that the third elevator car lining panel 83 does not abut against the structural panel 44 of the rear wall 9. Instead, the third elevator car lining panel 83 ends in some distance from the structural panel 44 of the rear wall 9 providing a gap 36 between the edge of the third elevator car lining panel 83 facing the rear wall 9 and the structural panel 44 of the rear wall 9.
A fourth elevator car lining panel 84 extending basically parallel to the structural panel 44 of rear wall 9 is arranged in said gap 36. Thus, the fourth elevator car lining panel 84 is arranged between the structural panel 44 of the rear wall 9 and the arcuate portion of the third elevator car lining panel 83.
The extension (width) of said fourth elevator car lining panel 84 in a dimension parallel to the plane of the structural panels 44-46 of the rear wall 9 is shorter than the extension (width) of the first to third elevator car lining panels 81-83 arranged parallel to the side wall 6. The dimension of the fourth elevator car lining panel 84 in the direction parallel to the rear wall 9 in particular is substantially equal to the dimension of the portion of the third elevator car lining panel 83 extending parallel to the rear wall 9. As a result, the fourth elevator car lining panel 84 is covered by the third elevator car lining panel 83 and not visible from the elevator car's 2 interior space 3.
The edge of said fourth elevator car lining panel 84 facing away from the side wall 6 (i.e. facing to the right side in
The first connection portion 10 is fixed to the structural panel 44 of the rear wall 9 by means of at least one fixing element 16 (which is not shown in
A fifth elevator car lining panel 85 is arranged next to the fourth elevator car lining panel 84. The edge of the fifth elevator car lining panel 85 facing the fourth elevator car lining panel 84, which is shown on the left side in
The edge of the fifth elevator car lining panel 85 facing away form the fourth elevator car lining panel 84 (i.e. facing to the right side in
A similar configuration, which is mirrored with respect to an imaginary central plane extending parallel to the side walls 6, 7 through the center of the elevator car 2, is provided in the right rear corner 39 of the elevator car 2. This configuration is illustrated in
A seventh elevator car lining panel 87 and an eighth elevator car lining panel 88 correspond to the fifth and the fourth elevator car lining panels 85, 84 respectively, and a ninth and a tenth elevator car lining panel 89, 90 respectively correspond to the second and third elevator car lining panels 82, 83, which are located at the opposing sidewall 6.
With the structure of elevator car lining panels 81-86 according to exemplary embodiments of the invention, the side walls 6, 8 and the rear wall 9 of the elevator car 2 may be covered completely by elevator car lining panels 81-90. The elevator car lining panels 81-90 are securely attached to each other and/or to the structural panels 44-49 of the elevator car 2.
In the embodiments, which are illustrated in the figures, the elevator car lining panels 84-88, which are attached to the structural panels 44-46 forming the rear wall 9 of the elevator car 2, are not mechanically connected to the elevator car lining panels 81-83, 89, 90 arranged at the side walls 6, 7. This separation allows to compensate for mechanical tolerances and/or thermal expansion of the car lining panels 81-88 and avoids the generation of any undesirable mechanical stresses in the structure formed by the elevator car lining panels 81-89.
The skilled person, however, will easily understand that in an alternative configuration the car lining panels 84-88 attached to the structural panels 44-46 forming the rear wall 9 of the elevator car 2 may be mechanically connected to the elevator car lining panels 81-83, 89, 90 arranged at the side walls 6, 7 of the elevator car 2 by employing the same principles as they have been described before. In particular, the elevator car lining panels 83, 89 arranged in the rear corners 38, 39 of the elevator car 2 may be provided with additional connection portions 10, 12 which are configured for connecting the elevator car lining panels 83, 89 at the rear corners 38, 39 with the car lining panels 84-88 attached to the structural panels 44-46 of the rear wall 9. Alternatively or additionally, additional flexible or rigid connection means may be used for realizing said connection.
The skilled person will also easily understand that the number of adjacent structural panels 41-49 and elevator car lining panels 81-90 shown in the figures is only exemplary. Further exemplary embodiments of the invention may employ any number of adjacent structural panels 41-49 and elevator car lining panels 81-90 located at the side walls 6, 7 and the rear wall 9, respectively. Further, the extension (width) of the structural panels 41-49 may be different from the extension (width) of elevator car lining panels 81-90. This will result in a difference between the numbers of structural panels 41-43, 47-49 and the numbers of elevator car lining panels 81-83, 89, 90 arranged along each of the side walls 6, 7.
Further Embodiments:
A number of optional features are set out in the following. These features may be realized in particular embodiments, alone or in combination with any of the other features.
In an embodiment the at least one first connection portion extends along a first edge of the elevator car lining panel and/or the at least one second connection portion extends along a second edge of the elevator car lining panel, in particular in a vertical direction. Connection portions extending along the edges of the elevator car lining panels allow for a secure connection over the whole height of adjacent elevator car lining panels.
In an embodiment the first edge of the elevator car lining panel is located opposite to the second edge of the elevator car lining panel allowing to sequentially attach a plurality of elevator car lining panels to each other forming a row of adjacent elevator car lining panels, which are connected to each other.
In an embodiment each of the elevator car lining panels is formed from a single piece of sheet material. This allows to produce the elevator car lining panels easily and at low costs, e.g. by extrusion.
In an embodiment at least one of the first and second connection portions is formed by bending a sheet material. Bending is a cheap and reliable method for forming the connection portions. Bending in particular avoids the need of attaching an additional material to the elevator car lining panels when forming the connection portions.
In an embodiment the sheet material comprises a metal, in particular aluminum. Elevator car lining panels formed from metal are very fire retardant. This characteristic considerably enhances the safety of the elevator system. Aluminum is a light material. Thus, elevator car lining panels made of aluminum do not add much additional weight to the elevator car. A light elevator car is easier to move than a heavy elevator car. Thus, reducing the weight of the elevator car reduces the energy which is needed for operating the elevator system.
In an embodiment the sheet material of the elevator car lining panels is laminated in order to improve the mechanical and optical properties of the elevator car lining panels. By laminating the sheet material undesirable light reflections at the surface of the elevator car lining panels can be reduced or even completely suppressed. A sandwich structure comprising a laminated sheet material further may have an increased mechanical strength, in particular with respect to bending forces acting on the elevator car lining panel.
In an embodiment at least one of the first and second connection portions comprises a clipping mechanism which is configured for engaging with a corresponding connection portion provided at an adjacent elevator car lining panel. A clipping mechanism provides reliable and convenient means for securely connecting adjacent connection portions to each other.
In an embodiment the fixing structure comprises at least one opening configured for receiving at least one fixing element in order to pass through said opening. Such a combination of at least one opening and at least one corresponding fixing element allows to fix the elevator car lining panel securely to at least one structural panel of the elevator car.
In an embodiment any fixing elements passing through the openings provided in the at least one first connection portion are not visible and/or are not accessible when the at least one first connection portion is connected with a corresponding second connection portion of an adjacent elevator car lining panel. The fixing elements in particular may be covered by at least a portion of the second connection portion. This prevents passengers residing in the interior space of the elevator car from being injured or damaging their clothing by contacting the fixing elements. It further prohibits an unauthorized removal of the fixing elements by the passengers and it provides an aesthetic configuration of the elevator car's interior space.
In an embodiment the elevator car lining panel comprises at least one arcuate edge portion to be arranged in a vertically extending corner of the elevator car. An elevator car lining panel comprising an arcuate portion is very convenient to be arranged in a corner of the elevator car. An arcuate portion in particular avoids any sharp edges which may cause injury or damage.
In an embodiment the elevator car lining panel comprises a receiving portion which is configured for accommodating at least one lighting element.
In an embodiment the at least one lighting element comprises at least one of a neon tube, a fluorescent lamp and one or more LEDs for providing a convenient and efficient light source.
In an embodiment of an elevator car according to an exemplary embodiment of the invention at least one lighting element is arranged in the receiving portion of at least one elevator car lining panel. Arranging at least one lighting element in a receiving portion provided by an elevator car lining panel allows to conveniently illuminate the interior of the elevator car.
A method of assembling an elevator car according to a further exemplary embodiment of the invention additionally comprises the step of connecting a third elevator car lining panel with the first and/or second elevator car lining panel and attaching the third elevator car lining panel to at least one of the structural panels of the elevator car.
An additional (fourth) elevator car lining panel may be attached in the same way to the third elevator car lining panel etc. By sequentially attaching a plurality of elevator car lining panels, at least one wall of an elevator car may be covered completely by elevator car lining panels securely attached to each other.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition many modifications may be made to adopt a particular situation or material to the teachings of the invention without departing from the essential scope thereof.
