Definitions

• the present invention relates to an elevator cabin skirting assembly.
• the reference field for the invention is the elevator cabin.
• Cabin skirting is a component that is used inside the elevator cabin on the bottom side of the cabin wall, at a certain height from the cabin floor.
• the usage of a skirting has several reasons: esthetical view inside the cabin, hiding unexpected view of the wall's bottom side, preventing any damage to the wall's bottom side during the usage of the elevator which may be caused by any wheeled transport vehicle hit or passenger's vandal foot strike. Without skirting these damages will be directly on the wall panels which is difficult to maintain. It indeed requires disassembly of whole wall panels which means more or less the whole cabin and the related components, so it will require much effort and time. To avoid these issues a skirting is placed at the bottom side of the wall and, in case of any damage, it should be easily replaceable.
• skirting there are several different installation methodologies for skirting.
• the easiest solution is to fix the skirting with screws behind the walls, which means during the installation and in case of maintenance of the skirting the operator must be inside the elevator shaft outside the cabin. This requires two operators for assembly and maintenance of the skirting and it also means that a greater gap between the external side of the wall and the shaft wall is needed.
• More advanced solutions are some kind of plug, clip solutions which are easy to install from inside the car and easy to maintain.
• the skirting is positioned by applying force on it to fix the clip/plug.
• the issue with this methodology is also if you apply a force in the opposite direction you can easily remove the skirting. Normal passengers also could force in the opposite direction to remove it, stealing it.
• Another issue is that generally this type of clip/plug structure requires more advanced production methodology.
• the technical task underlying the present invention is to propose an elevator cabin skirting assembly, which overcomes the drawbacks in the prior art as described above.
• an object of the present invention is to provide an elevator cabin skirting assembly, which is easily installable from inside the cabin by one person, without being visible and easily accessible for a passenger.
• Another objective of the present invention is to make available an elevator cabin skirting assembly, which does not need to use any tool for installation.
• an elevator cabin skirting assembly comprising:
• the end portion in the first position covers at least partly the second cutout.
• the skirting assembly comprises a second bushing fixed to the cabin wall at the internal surface side and protruding from it, said skirting member having a folded edge supported on the second bushing.
• the shaped protrusion comprises an inclined plate which develops through the first cutout and an engaging plate originating from an end of the inclined plate transversely to it, at least a part of the engaging plate protruding below the skirting member.
• the skirting member comprises:
• the lower edge has a first passage, the shaped protrusion developing through said passage so as to protrude below the skirting member.
• the upper edge comprises:
• number 1 indicates an elevator cabin skirting assembly.
• the skirting assembly 1 comprises a cabin wall 2.
• the cabin wall 2 has an inner surface 2a and an outer surface 2b.
• a first cutout 3 and a second cutout 4 are obtained on the cabin wall 2, both having development through it between the inner surface 2a and the outer surface 2b.
• the skirting assembly 1 comprises a bracket plate 5 arranged at the outer surface 2b side.
• the bracket plate 5 has an end portion 51 comprising a shaped protrusion 52.
• the shaped protrusion 52 passes through the first cutout 3 to protrude from it at the inner surface 2a side.
• the skirting assembly 1 comprises a skirting member 6 mounted on the cabin wall 2 at the inner surface 2a side.
• the skirting member 6 is positioned so that at least an end of the shaped protrusion 52 protrudes below the skirting member 6. Therefore, a grip and push for the fingers of the operator is allowed, without being visible at the normal eye level of passengers.
• the shaped protrusion 52 comprises an inclined plate 521 which develops through the first cutout 3 and an engaging plate 522 which develops from an end of the inclined plate 521 transversely to it. At least a part of the engaging plate 522 protrudes below the skirting member 6 so as to be engaged by the operator to move the end portion 52.
• the skirting assembly 1 comprises a first bushing 7 fixed to the skirting member 6 and inserted in the second cutout 4 of the cabin wall 2.
• the first bushing 7 serves to limit horizontal movement of the skirting member 6 with respect to the cabin wall 2.
• For “horizontal” is intended movement of the skirting member 6 along a direction which is parallel to the bottom side of the cabin wall 2.
• the bracket plate 5 is pivotally attached to the outer surface 2b of the cabin wall 2 so that at least the end portion 51 is movable towards/away with respect to the cabin wall 2.
• the end portion 51 is configurable at least in a first position, in which the end portion 51 is close to the cabin wall 2 and prevents the first bushing 7 to disengage the second cutout 4, and a second position, in which the end portion 51 is spaced from the cabin wall 2 and allows the first bushing 7 to move.
• bracket plate 5 when the end portion 51 is in its first position, acts as a movement limiting device for the first bushing 7.
• the bracket plate 5 is riveted to the cabin wall 2 at one point opposite to the end portion 51.
• bracket plate 5 is shaped and arranged so that the end portion 51 in the first position covers at least partly the second cutout 4, in particular the portion above the first bushing 7.
• the first bushing 7 comprises an enlargement of section and the second cutout 4 is designed as a keyhole comprising a round-like aperture 4a and a tab-like aperture 4b originating from the round-like aperture 4a.
• the tab-like aperture 4b is below the round-like aperture 4a.
• the first bushing 7 can pass through the round-like aperture 4a but not through the tab-like aperture 4b due to the enlargement of section.
• the first bushing 7 is of the mushroom type.
• the first bushing 7 when inserted rests on the tab-like aperture 4b.
• the end portion 51 of the bracket plate 5 covers at least partly the round-like aperture 4a. In other words, in the first position the end portion 51 prevents the first bushing 7 to move from the tab-like aperture 4a, thus preventing disengage.
• the skirting assembly 1 comprises a second bushing 8 fixed to the cabin wall 2 at the internal surface 2a side and protruding from it.
• the skirting member 6 has a folded edge supported on the second bushing 8. In this way, when installed, also the upper part of the skirting member 6 is limited for any movement on the horizontal side.
• the skirting member 6 comprises a main plate 61 having elongated development according to a first direction.
• the first direction is substantially parallel to a bottom side of the cabin wall 2.
• the main plate 61 has an upper edge 61a and a lower edge 61b folded towards the cabin wall 2 so that, when the skirting member 6 is mounted on the cabin wall 2, a confined space is defined between the skirting member 6 and the cabin wall 2.
• the first and second cutouts 3, 4 are obtained on a part of the cabin wall 2 which defines the confined space.
• the upper and lower edges 61a, 61b have elongated development according to directions substantially parallel to the first direction.
• the lower edge 61b has a first passage 62.
• the second cutout 4 is covered at the inner surface 2a side by the skirting member 6 and the shaped protrusion 52, in particular the engaging plate 522, develops through the first passage 62 so as to protrude below the skirting member 6.
• the shaped protrusion 52 passes through the first cutout 3, develops through the confined space between the skirting member 6 and the cabin wall 2 and passes through the passage 62 for protruding below the skirting member 6.
• the upper edge 61a and the lower edge 61b comprise:
• the second portion 64 develops parallel to the main plate 61 and to the length of the bottom side of the cabin wall 2.
• the first portion 63 defines a 90° bending with respect to the main plate 61 and the second portion 64 defines a further 90° bending with respect to the first portion 63.
• the second portion 64 faces the cabin wall 2.
• the second portion 64 of the upper edge 61a has a second passage 65 for accommodating the second bushing 8.
• the second portion 64 of the upper edge 61a is supported on the second bushing 8 at second passage 65.
• the first passage 62 of the lower edge 61b is obtained in both the first portion 63 and second portion 64 of the lower edge 61b.
• the first bushing 7 is fixed to the second portion 64 of the lower edge 61b.
• the skirting member 6 To install the skirting member 6, it is only needed to put it against the cabin wall 2 and then pushing it down towards the cabin floor.
• the first bushing 7 is inserted in the second cutout 4, causing the end portion 51 of the bracket plate 5 to move away from the cabin wall 2 and free the area for the passage of the bushing 7. Then, the first bushing 7 is moved down in the second cutout 4 until reaching of the bottom part.
• the skirting member 6 is mechanically fixed for any horizontal movement.
• the upper part of the skirting member 6 is limited for any movement on the horizontal side.
• the last portion of the shaped protrusion 52 protrudes below the skirting member 6. It is therefore located between the bottom side of the skirting member 6 and the cabin floor.
• the end portion 51 moves back to the second position, thus allowing movement for the first bushing 7 upwards through the second cutout 4.
• the first bushing 7 reach the top of the second cutout 4 and the skirting member 6 can be pulled back and removed from the wall 2.
• An elevator cabin 100 is also object of the present invention.
• the elevator cabin 100 comprises a skirting assembly 1 as described above.
• the installation of the skirting assembly proposed can be easily performed by one person from inside the cabin. Moreover, there is no need to use any tool.
• the shaped protrusion protrudes below the skirting member but for a tiny part so that it allows grip and push for the fingers of the operator, without being visible at the normal eye level of passengers. Without knowing the approximate position of the shaped protrusion, it is not possible to remove the skirting member. Any maintenance operator can easily remove the skirting member by referring to the installation/maintenance manual, but normal passengers cannot remove it.
