FR2682541A1 - Device for driving a gate by an electric motor - Google Patents

Abstract

The drive device essentially comprises a tubular motor (5) including a tubular casing (8) driven in rotation, on which latter at least one link rod (12) is fixed for driving a gate leaf. This device exhibits several advantages, such as independence of the vertical positioning of the motor and of the link rod, capability of fixing several link rods to the same tube, and overcoming the risks of pinching between the link rod and the housing of the motor.

Description

The present invention relates to a driving device

  gate arrangement comprising an associated electric motor

  linked to a reducer and driving, via the reducer, a rod intended to drive the gate. Many devices of this kind are known, some of which are described in US Patents 2,032,724, FR

2,307,109 and FR 2,330,837.

  In all these devices, the control rod is

  fixed on the output shaft of the reducer, which reduces

  tor is generally mounted in a housing containing the motor, housing constituting a unit commonly called gearmotor The relative movement between the

  connecting rod and the gearmotor housing has been occa-

  the cause of pinch-in accidents between

  the rod and the gearmotor On the other hand, the height

  tor to which the link is attached to the gate or, conversely, to the pillar supporting the gate, and determined by the position of the motor Finally, it is not

  hardly possible to provide a second connecting rod

  dragging, at a certain distance from the first, in the case where it is desired to drive the gate at two points, for example in the case of leaves of

gate of high height.

  The object of the present invention is to provide a

  portal drive if obviated

  aforementioned mentions Positively, the invention has for

  purpose of eliminating the risks of pinching and shearing-

  Lement, to achieve a certain independence between the level of attachment of the engine and the level of attachment of the link to the portal and allow to simply drive several links by the same motor

different levels.

  The drive device according to the invention is

  characterized in that the motor and its reducer consist of a tubular type gearmotor whose tubular casing is rotated by the reducer and that the link is fixed to said envelope

  tubular frame so as to be driven by it

  this. The casing of the tubular gearmotor rotating with the link, there is no longer any risk of pinching between

the link and this envelope.

  The tubular gearmotor being arranged vertically

  and the link can be fixed at any point

  that of this tubular casing, the gear motor, which will be called to simplify tubular motor, can be fixed on the pillars of the portal at a height

  standard, while the link can be attached to the mo-

  tubular tor at the desired height or at the height imposed by the gate This gives a large

installation flexibility.

  That the link is fixed by a collar surrounding the

  tubular motor tube or in a longitudinal groove

  nale of it or by any other means, it is without other possibility to fix two or more rods

on the same tubular motor.

  The tubular motor also has an aesthetic advantage since it is generally of a reduced diameter and it fits in the line of the portal pillar. This reduced diameter also has the advantage of allowing a large angular deflection of the gate leaf, such a deflection can be

  necessary in the case of oblique access to the portal.

  The accompanying drawing shows, by way of example,

  ques embodiments of the invention.

  partially represented with its pillar.

  Figure 2 is a sectional view along II-II of the arrangement

sitive shown in Figure 1.

  Figure 3 shows the same device with two

drive rods.

  of execution cross-section view according to IV-IV, fi-

gure 5.

  Figure 5 is a sectional view along V-V of the device

tif shown in Figure 4.

  FIG. 6 schematically represents a first mode

  for fixing the drive device and a van

tail on a pillar.

  FIG. 7 schematically represents a second mode

  for fixing the drive device and a van

tail on a pillar.

  Figure 8 shows a third mounting example

  in which the tubular motor is integral with the holder

  tail. Figure 9 shows schematically a fourth

mounting method.

  Figures 1 and 2 partially show a pillar 1 supporting a leaf 2 of a partially shown portal This leaf is mounted on three hinges of which we see the two upper hinges 3 and 4 On the pillar 1 is fixed vertically a tubular motor 5 Such tubular motor is known for winding blinds and rolling shutters Such a tubular motor is described for example in French patents 2,480,846 and 2,376,285 The tubular motor 5 comprises, in known manner, a geared motor assembly 6, of which the output of the reducer drives a disc 7 secured to a tube 8 constituting the casing or casing of the gearmotor The tubular motor 5 is mounted between two brackets 9 and fixed to the pillar 1 The gearmotor housing 6 is immobilized in rotation on the bracket 9, while the tube 8, provided with an end of an axis, rotates on the bracket used as a bearing The upper end of the

tube 8 rotates on a ring 11.

  On the tube 8 is radially fixed a link 12 provided for this purpose with a collar 13 which can be tightened around the tube 8 by means of a bolt / nut assembly 14 The end of the link 12 is articulated at the end d an arm 15 around an axis 16, the arm 15

  being itself hinged on leaf 2.

  It is immediately noted that the link 12 can be

  positioned at will on tube 8 of the tubular motor

  re, both angularly and longitudinally The tubular motor 5 can therefore occupy a standard position on the pillar 1, without it being necessary to be concerned with the point of attachment of the arm 15 to the leaf 2 The possibility of angular positioning can also facilitate, in certain realizations, the

  engine stop point adjustment.

  It will be noted that, unlike the outlet axis of the prior devices, the tube 8 has a relatively large diameter allowing the transmission of a torque.

important to the link 12.

  FIG. 3 represents an embodiment in which the drive device must drive a leaf

  17 having a great height and consequently su-

  torsional jet In this case the tube 8 of the mo

  tubular tor of FIG. 1 so as to obtain a tube 8 ′ and two rods 12 and 12 ′ are fixed on this tube 8 ′ at two different levels so as to drive

  leaf 17 at two points of very different levels

  rents The moment of inertia of a tube, in the case

  particular to the 8 'tube, being very important, the 8' tube

  allows, despite its height, to offer a good resistance

torsional strength.

  The tube 8 does not necessarily have to be of circular cylindrical section, but it can be of any section, in particular polygonal. An example of polygonal section is shown in FIGS. 4 and 5 The tube

  of polygonal section 18 is produced by means of a pro-

  yarn having a longitudinal groove 19 in a T profile in which a connecting rod 20 is fixed by means of a double bracket 21 bolted to the rod 20 and a ply plate 22 housed in the groove 19 and fixed by two bolts to the double bracket 21 The groove 19 also makes it possible to fix one or more connecting rods

  20 at any level of the tubular motor The use of

  sation of a profile also makes it possible to easily personalize the device by processing the profile,

  both in terms of shape and color.

  Figures 6 to 9 illustrate, by way of example, which

  only examples of mounting the device.

  FIG. 6 represents a conventional assembly in which the tubular motor 5 is fixed to the pillar 1 and the hinges 3, 4 of the leaf 2 are on one of the faces of the pillar Ce

  mounting allows opening of the leaf to 900.

  The assembly illustrated in Figure 7 differs from the assembly shown in Figure 6 in that the hinges 3, 4 are mounted on an edge of the pillar 1 adjacent to the face of the pillar on which the tubular motor is fixed 5 This assembly allows an opening leaf 2 over

  900, opening made even easier by the small footprint

  horizontal of the tubular motor 5.

  The assembly shown in FIG. 8 is characterized by the fact that the tubular motor 5 is mounted on the valve 2, while the arm 15 is articulated on a wall 23.

  In the assembly shown in Figure 9, the motor tu-

  ball 5 is fixed on the pillar 1 and the arm 15 is deleted, replaced by a slide 24 integral with the leaf 2 and in which a roller mounted at

the end of the link 12.
