FR2960019A1 - Device for electrically opening and closing e.g. shutter, has tube connected with hook and supported on trigger, and electric motor driving shaft placed on ball bearings that act on hook to turn direction of shaft - Google Patents

Abstract

The device has a tube i.e. stick (6), connected with a hook (9) and supported on a trigger. An electric motor (13) drives a shaft (4) placed on ball bearings that act on the hook to turn direction of the shaft. An ergonomic bracket (16) is placed in the electric motor with a driving pinion. A shouldered sleeve ensures a junction between the ergonomic bracket and the tube. The shaft drives a male part. A female part is blocked by a pin. The tube is made of aluminum, poly-carbon or composite material.

Description

-1-

The present invention relates to a device for electrically opening and closing a blind, a shutter, or all openings, using a rod equipped with an electric motor driving at its end a hook for raising and lowering it. the invention consists of a motor part, a shaft and its hook attachment The opening of these equipment was traditionally done using a hand crank manually by the person who wanted to open or close his shutter. Often users were mistaken in the direction of the march, and the fragile people often had difficulties to maneuver this crank, to see impossible in certain cases, after a winter period; seizing of the drive, wear of the mechanical parts and lack of lubrication, the system becoming obsolete and unusable.

The device according to the invention overcomes all these disadvantages and provides comfort in its use. It comprises in fact according to a first characteristic an aluminum tube equipped with a wireless electric motor and on the other side a hook for opening or closing a shutter or a terrace awning When a user presses the trigger of the stick, the electric motor rotates in the desired direction rotating a hook fixed in the ring of the flap to maneuver downhill or mounted.

According to the embodiments,

- The tube can be made of aluminum, polycarbonate or composite material The diameter of the tube or rod can vary from 30 to 50 m / m - the battery voltage is variable: from 4.5 to 9 volts - a plug with transformer ( 12 V) is provided in the event of battery failure - the hook is made of stainless steel - the ball bearings are sealed - the motor drive part can be hexagonal, square or flat 25 - the motor torque is very powerful thanks to its reducer - the number of rotational revolutions corresponds to the normal speed of a manual action - electrical safety standards are respected (EN) - the length of the cane is adjustable according to the models, - the motor-carrying handle varies according to the angle of use, straight 180 ° or inclined 60 ° 30 - the drive shaft (4) is made of stainless steel tube

The accompanying drawings illustrate the invention:

FIG. (1) represents the description of the invention. FIG. (2) represents the moving parts of the invention and its operation. FIG. (3) represents the detail of certain views in section AA. With reference to these drawings, FIG. device comprises a low voltage electric motor (13) equipped with small batteries which actuates a powerful gearbox. A tube (6) called rod is equipped at its end with a hook (9) hinged, replacing the old crank type automotive. No more desperate strains to find the best angle of rotation, efforts to unlock the ring long blocked by a winter without use and 40 no source of error in the direction of rotation of the electric crank for the climb 2960019 -2-

or the descent of the shutter. Finally an ease of operation, more effort to provide during handling. The electric crank meets all your expectations.

It comprises in fact an electric motor part (13) provided with a trigger (14) for the rise and a trigger (15) for the descent. The ergonomic butt (16) is removable as to its use, either 180 ° straight or 60 ° inclined according to the position of the user for a better comfort in the maneuver. The motor part (13) is equipped at its end with a sleeve (1) receiving a pinion (10) and its washer (2). On the front part of the sleeve (1) we find a female fitting (12), it can be hexagonal, square or flat. An aluminum tube (6) with a diameter of 30 m / m is composed at its motor end (13) of a male octagonal part (11) which serves to drive the transmission shaft (4) where is mounted a ball bearing (5) ensuring a perfect rotation of the shaft (4) in the tube (6). A pin (3) of the "mechanindus" type ensures the attachment of rotating assemblies. The tube (6) is equipped at its end hook side (9) of a sleeve (8) which fits perfectly on the tube (6). A ball bearing (7) is mounted on the shaft (4) on the sleeve side (8) in order to perfectly maintain the shaft in its housing and to ensure equilibrium when the shaft (4) rotates in a rotational position. The portion of the sleeve (8) is machined at its end at 45 ° so as to allow the crank to work in different angles thus allowing easier rotation and to prevent it remaining straight.

According to a variant not illustrated, the butt (16) is articulated so as to be in the right position or inclined at 60 ° The device according to the invention is intended to replace the crank which was used before to open or close a shutter or blind manually replacing it with an electric rod. This system saves you from spending and replacing all your current systems. w LEGEND 1 Stepped machined sleeve 2 Thrust washer 3 Pin 0 4 4 Stainless steel drive shaft (tube) Sealed ball bearing 6 Aluminum or composite tube 7 Sealed ball bearing 8 45 ° chamfered and machined sleeve 9 Steel hook stainless steel sprocket drive 11 male part driveshaft drive 12 female part driveshaft drive 13 electric motor 14 electric trigger for climbing electric trigger for lowering 16 ergonomic tilting pedestal
