FR2805562A1 - Manual shutter opening and closing system, for remotely-controlled shutter, includes lever with handle operating connecting rod activating shutter, and cable connection ensuring motor drive arm is disengaged - Google Patents

Abstract

The manual shutter opening and closing system has a lever (18) decoupling an arm (7) from the reducer motor drive (1). A handle (33) operates a connecting rod (31) moving the shutter (35). The lever movement guarantees that the motor drive arm unlocks by using a cable connection (27) connected to the lever end.

Description

The present invention relates to a device providing manual opening and closing <B> to </ B> from a handful of a leaf equipped with a remote-controlled motorization system.

<B> It </ B> has already been installed a large number of automatic gates whose mechanism has an electric gearbox set fixed to the back of a pillar de ventail, has a vertical output axis to which is fixed the end of a horizontal arm perpendicular <B> to </ B> axis, the other end is thus brought <B> to </ B> browse a circular arc, this end itself having a rotating roller slid <B> to </ B> inside a rail fixed on the vane <B> to </ B> manceuvrer.

Moreover, these installations, including the geared motor is generally irreversible, can not be maneuvered manually and generally require intervention by uncoupling the gear motor of the arm. This operation often requires a key <B>, </ B> is difficult to achieve or impossible if the gate is closed and the user is <B> to </ B> outside.

The present invention proposes to remedy these drawbacks and to provide a decoupling device of the gear motor with respect to the arm by acting on a handle positioned on the window <B> to </ B> man # uvrer.

The device according to the present invention comprises two main elements.

A first so-called decoupling element comprising, on the one hand, a so-called mobile flange integral with the output axis of the geared motor and, on the other hand, the arm being able to be freely rotated relative to the movable flange integral with the output shaft of the reducing motor or can be secured to the mobile flange by engaging pivoting locking grains and engaging in the toothing of the mobile flange. Maneuver is possible by the rotation of a suitable cam under the action of a lever operated by a spring causing the engagement and maintenance of said grain in the toothing of the movable flange.

A second element composed firstly of a cable whose first end is secured to the engagement lever causing the rotation of the cam and whose second end is connected to a link capable of pivoting under a force exerted by the handle and on the other hand a sheath in which the cable slides stopped <B> at </ B> one end by a bracket secured to the arm of maneuver and secondly a bracket fixed on the gate <B> to </ B> manceuvrer. This sheath is intended to accept the variation in length between the two attachment points of the cable during the rotation of the gate.

Other features and advantages of the invention will emerge more clearly from the description which follows by seeing the appended drawings on which <B>: </ B> Figure <B> 1 </ B> is the sectional view of the decoupling device. Figure 2 is the sectional top view of the locked system.

Figure <B> 3 </ B> is the sectional top view of the unlocked system.

Figure <B> 6 </ B> is the side view of the system unlocked Figure <B> 7 </ B> is the sectional view of the roller guidance Figure <B> 8 </ B> is the view from below showing the manual movement of the leaf If one refers <B> to </ B> the example of realization illustrated in the figure <B> 1 </ B> and in figure 2 representing the locked system, < B> 1 </ B> 'output shaft (2) irreversible gear motor <B> (1) </ B> is integral with the circular flange said mobile <B> (3) </ B> through a ring (4) welded to said movable flange <B> (3) </ B> and by <B> 1 </ B> 'axis (2) engaging in the bore of the ring, the together being immobilized by a through pin <B> (5). </ B>

The movable flange <B> (3) </ B> has an internal toothing (4) made by semi-cutting the material, this internal toothing (4) with a pitch of about 2 'is treated to provide sufficient strength < B> to </ B> wear. With this mobile flange <B> (3) </ B> cooperates the end <B> (6) </ B> of the maneuvering arm <B> (7). </ B> On this end <B > (6) </ B> is positioned two grains <B> (8), </ B> (8 ') pivoting around 2 axes <B> (9), </ B> (9') and having on the outer contour a toothing <B> (10), </ B> (10 ') engaging in the toothing (4) of the movable flange <B> (3) </ B> under the action of a cam <B> (11). </ B> The teeth (4) of the mobile flange <B> (3) </ B> and <B> (10), </ B> (10 ') grains <B > (8), </ B> (8 ') are identical to allow proper engagement and undergo processing to obtain a resistance <B> to </ B> sufficient wear. The grains <B> (8), (8) </ B> and the cam <B> (11) </ B> have a thickness less than two tenths of a millimeter compared to <B> to </ B> the height of the toothing (4) of the mobile flange <B> (3) </ B> guaranteeing perfect operation. The end <B> (6) </ B> of the arm <B> (7) </ B> is centered on the mobile flange <B> (3) </ B> via pins (12) integral with the end <B> (6) </ B> of the arm <B> (7) </ B> by welding whose positioning on the end <B> (6) </ B> and the diameter < B> (13) </ B> are defined to have a minimum clearance with the outer diameter (14) of the movable flange <B> (3). </ B> The pegs (12) have a retainer <B> (15). ) </ B> allowing vertical hold of the <B> (6) </ B> end of the <B> (7) </ B> arm relative to the moving flange <B> (3). </ B > An axis <B> (16) </ B> integral with the cam <B> (11) </ B> crosses the end of the arm <B> (6), <B> presents <B> to < / B> its lower end a diameter <B> (17) </ B> allowing the attachment by welding of a lever <B> (18) </ B> whose operation will be described later.

The figure <B> 3 </ B> represents a top view of the grains <B> (8), </ B> (8 ') released from the toothing (4) of the mobile flange <B> (3) </ B> and thus the free rotation of the arm <B> (7) </ B> with respect to the mobile flap <B> (3). </ B>

The clearance of the grains <B> (8), </ B> (8 ') of the toothing (4) of the mobile flange <B> (3) </ B> is achieved by rotation of the cam <B> (11). ) </ B> of approximately <B> 30 '</ B> caused by the movement of the lever <B> (18) </ B> secured to the cam <B> (11) </ B> and by the contact of the <B> (19), (19 ') </ B> part of the cam <B> (3) </ B> on the opposite zones (20), (20') of the grains <B> (8) ), </ B> (8 '). Thus in this case the arm <B> (7) </ B> centered and retained by the pins (12) can rotate freely around the movable flange <B> (3) </ B> when the lever <B> (18) ) </ B> is held moved maintaining the same relative position relative to the arm <B> (7) </ B> when it is rotating.

Figure 4 shows the entire device in view from below and the operation of the release system <B> to </ B> from the handle positioned on the ventail.

The irreversible gear motor assembly <B> (1) </ B> is secured to the pillar (21) by means of a support and screws not shown. Arm <B> (7) </ B> has <B> at </ B> the first end <B> (6) </ B> the locking and unlocking system <B> to </ B > the axis (2) of the geared motor whose operation is described above and <B> to </ B> the second end an axis (22) provided with a roller <B> (23) </ B> sliding freely <B> to </ B> the inside of the rail <B> (36) </ B> attached to the leaflet <B> (35) to </ B> man # uvrer. On the arm <B> (7) </ B> a bracket (24) is fixed by welding in alignment and facing the end of the lever <B> (18). </ B> This bracket (24), to <B> to </ B> receive a duct stop <B> (25) </ B> on the ventail side and a compression spring <B> (26) </ B> lever side <B> (18), </ B> is intended to <B> to </ B> hold this <B> (18) </ B> lever away from the <B> (7) </ B> arm and thus ensure grains <B> (8), </ B> (8 ') whose operation <B> has already been </ B> described. On the end of lever <B> (18) </ B> is attached the first end of a cable <B> (27). </ B> This cable <B> (27) </ B> goes < B> to </ B> the inside of the spring <B> (26) </ B> crosses the square (24) then crosses a sheath <B> (28) </ B> stopped on the square (24) ) by the first duct stop <B> (25). </ B> The duct assembly (28) and cable <B> (27) </ B> is extended towards the portal, the duct <B> (28). ) </ B> stopping on a second sheath stop <B> (29) </ B> stopped by the square <B> (30) </ B> attached to the vent <B> (35) </ B> and fixed by screws not shown. The cable <B> (27) </ B> passing through the second sheath stop <B> (29) </ B> and the square <B> (30) </ B> hangs on the link < B> (31) </ B> secured to an axis <B> (32) </ B> and a handle <B> (33) </ B> to exert effort and to cause rotation of the connecting rod <B> (31) </ B> rotating around the axis <B> (32) </ B> and guided on the portal <B> (35) </ B> by the bearing (34) .
