Definitions
- the present invention relates to a telescopic apron for an elevator car.
- a car apron or platform guard is a safety device that prevents the inadvertent fall of rescued persons into the lift shaft beneath the car.
- the apron shall at least cover the clear width of the cabin door with the lowest sheet.
- the minimum open length of the car apron is 750 mm.
- the telescopic or foldable design allows the car apron to fit in new plants of existing buildings, where the minimum open length may be an issue.
- a hydraulic damper is usually provided for preventing the uncontrolled fall of the panels.
- the technical task underlying the present invention is to propose a telescopic apron for an elevator car, which overcomes the drawbacks in the prior art as described above.
- the aim of this invention is to make available a telescopic apron for an elevator car, having a simplified structure with respect to the known solutions and achieving the same level of safety in terms of preventing the fast fall of the panels when the apron is opened.
- a further aim of the present invention is to propose a telescopic apron for an elevator car that is easy and fast to assemble.
- a telescopic apron for an elevator car comprising:
- each rail piece is fixed to the corresponding panel by two screws that are applied to the two ends of the rail piece.
- these two screws are also stop elements for the sliding of the corresponding sliding block when the panels are in the retracted configuration.
- each longitudinal protrusion of the corresponding sliding block has a hole with a longitudinal extension.
- the hole is coupled to a further screw that is fixed to the facing rail piece.
- the further screw is a stop element for the mutual sliding of the sliding block and the rail piece when the panels are in the extended configuration.
- the telescopic apron 1 indicates a telescopic apron for an elevator car.
- the telescopic apron 1 comprises a plurality of panels 2 that are mounted in a telescopic arrangement.
- the panels 2 are movable, i.e mutually slidable, so that the telescopic apron may assume two limit configurations, i.e.
- the telescopic arrangement is obtained by means of rails 3.
- Each rail 3 comprises two mutually slidable rail pieces 3a, 3b that are fixed to adjacent panels 2 by screws 4, 5 each.
- Each rail 3 comprises a sliding block 6 having a longitudinal extension and two longitudinal protrusions 6a, 6b.
- Each rail piece 3a, 3b has a longitudinal groove 7 in which one of the longitudinal protrusion 6a, 6b of the sliding block 6 is slidably inserted.
- the rail pieces 3a, 3b are made of plastic material, preferably cast polyamide.
- the sliding block 6 is made of metal, preferably steel.
- each rail piece 3a, 3b is fixed to the corresponding panel 2 by at least two screws 4, 5 that are applied to the two ends of the rail piece 3a, 3b.
- the two screws 4, 5 are stop elements for the sliding of the corresponding sliding block 6 when the telescopic apron 1 is in the folded configuration.
- the longitudinal protrusion 6a, 6b has a blind hole or a through hole 8 that has longitudinal extension.
- Each hole 8 is coupled to a further screw 9 that is fixed to the rail piece 3a, 3b in order to allow and guide the sliding of the sliding block 6.
- the further screw 9 represents a stop element for the mutual sliding of the sliding block 6 and the rail piece 3a, 3b when the telescopic apron 1 is in the unfolded configuration (see for example figure 9 ).
- the rail 3 may therefore assume:
- the special materials employed for the rail avoid the use of lubricant, thus simplifying the maintenance of the apron.
- the screws of each rail piece are also used as stop elements for the sliding of the corresponding sliding block (in the folded and in the unfolded configuration), thus simplifying the overall structure of the apron.
