Definitions
- the actuator of the invention comprises an electric motor 2 of vertical axis with its exit shaft emerging upwards and carrying a lead screw 4 engaging a helical gear 6 keyed onto a horizontal shaft 8.
- the entire assembly is housed in a casing 9 of high-impact plastic material or aluminium, comprising a lower portion 12 containing the motor 6 and intended to be buried, and preferably fixed by studs 13 embedded in cast concrete.
- the operation of the actuator of the invention is traditional in that by rotating the electric motor 2 in one or other direction, the pinion 20 rotates via the linkage consisting of the lead screw 4, the helical gear 6 and shaft 8, to provide translational movement of the door panel 24 by virtue of the engagement between the pinion 20 and the rack 22.
- the actuator does not hinder vehicle movement within the area closed by the door panel 24, and because of its shape considerably reduces the risk of being damaged by the vehicles themselves, by motorcycles, by children or by animals.

Abstract
Description
- The present invention relates to a mechanical actuator for sliding door panels; these generally comprise an electric motor and a speed reduction unit housed in a container of more or less parallelepiped shape, with a vertical wall from which there emerges a pinion engaging a rack rigid with the door panel to be moved.
- The container is positioned within the area closed by the door panel to be moved, in proximity thereto generally on a suitable concrete base, and extends upwards to represent an obstacle to the movement and parking of motor vehicles within the area closed by the door panel. The container is also subject to damage by children, animals, bicycles and motorcycles.
- According to the invention, these drawbacks are eliminated by a mechanical actuator for sliding door panels as claimed in claim 1.
- The present invention is further clarified hereinafter with reference to the accompanying drawings, in which:
- Figure 1
- is an overall perspective view of the actuator of the invention installed in proximity to a sliding door panel to be moved,
- Figure 2
- is a partly sectioned enlarged partial view of the actuator.
- As can be seen from the figures, the actuator of the invention comprises an
electric motor 2 of vertical axis with its exit shaft emerging upwards and carrying alead screw 4 engaging ahelical gear 6 keyed onto ahorizontal shaft 8. The entire assembly is housed in acasing 9 of high-impact plastic material or aluminium, comprising alower portion 12 containing themotor 6 and intended to be buried, and preferably fixed bystuds 13 embedded in cast concrete. - Sealedly fixed to the
lower portion 12 there is anupper portion 14 housing the speed reduction unit, which is formed from thelead screw 4 and thehelical gear 6. - The
upper portion 14 andlower portion 12 are preferably joined together by saidstuds 13, on whichnuts 16 are screwed, housed in cavities provided in theupper portion 14 and closable bysuitable caps 18. - The dimensions of the projecting
portion 14 are just sufficient to contain thehelical gear 6, so that the total height of thisupper portion 14 emerging from the ground is minimal and, because of its rounded shape, means that the overall size of the motor with speed reduction unit is virtually negligible. - The
horizontal shaft 8, on which thehelical gear 8 is keyed, emerges laterally from theupper portion 14 of thecasing 9 and carries keyed thereon apinion 20, which engages therack 22 of thedoor panel 24 to be moved. - The operation of the actuator of the invention is traditional in that by rotating the
electric motor 2 in one or other direction, thepinion 20 rotates via the linkage consisting of thelead screw 4, thehelical gear 6 andshaft 8, to provide translational movement of thedoor panel 24 by virtue of the engagement between thepinion 20 and therack 22. - However that which distinguishes the actuator of the invention from traditional actuators is the very small overall size of the actuator, most of which is buried with only a portion of minimal height emerging, just sufficient to allow engagement between its
exit pinion 20 and therack 22 applied to thedoor panel 24 to be moved. - Because of this minimal size, the actuator does not hinder vehicle movement within the area closed by the
door panel 24, and because of its shape considerably reduces the risk of being damaged by the vehicles themselves, by motorcycles, by children or by animals.
Claims (7)
- A mechanical actuator for sliding door panels with a motor (6) and a speed reduction unit (4, 6), characterised in that said motor and said speed reduction unit are housed in a buriable casing (9) which emerges from the ground by a minimum portion (14) housing a horizontal shaft (8) on which an operating pinion (20) for the door panel (24) is keyed.
- An actuator as claimed in claim 1, characterised in that the casing (9) comprises a lower portion (12) fixed by studs (13) embedded in concrete, in which a seat is provided for housing said lower portion (12).
- An actuator as claimed in claim 2, characterised in that the upper portion (14) of the casing (9) is fixed to the lower portion (12) by said studs (13) which fix said lower portion (12) to the concrete.
- An actuator as claimed in claim 3, characterised in that the upper portion (14) of the casing (9) is provided with cavities housing the upper end of the studs (13) and the nuts (16) for fixing said upper portion to them.
- An actuator as claimed in claim 4, characterised by comprising a closure cap (18) for each cavity.
- An actuator as claimed in claim 1, characterised in that said casing (9) is constructed of high impact plastic material.
- An actuator as claimed in claim 1, characterised in that said casing (9) is constructed of aluminium.
