Description

Manual portable device intended to unhinge swinging shutters in order to house them intramural, without risk, without difficulty, for a reverse procedure.

Currently in many countries: the majority of homes have swing shutters.

With nearly 15 million homes in France, one can count statistically on more than 100 million shutters, intended to be installed and removed for the purpose of their maintenance and their replacement.

As a general rule, the shutters are installed during the construction of the building with scaffolding.

In principle their maintenance is required approximately every 10 years (especially in coastal and humid regions without forgetting the harmful effects of the heat wave on their coating).

The problem of their handling exists whenever we want to maintain the shutters because it involves their disassembly to house them intramuros and reattach them again on their hinges after restoration or replacement.

In all cases, this intervention is painful, dangerous manually because it is not expensive with lifting equipment.

However, it is very pleasant to have beautiful shutters at home, hence the problem of their maintenance or that of their replacement.

This action, if it is manual, remains very painful in addition to being dangerous 20 because the shutters often after bad weather weigh up to 40 kg and more (depending on their surface and their thickness) and they become very difficult to handle after arms.

In these cases the solution of cranes or scaffolding in addition to being very expensive is very often impossible due to the environment (narrow streets 25, inaccessible flowerbeds etc.)

The present invention provides the solution of ease and speed avoiding any danger.

Based on prior art research, there is no practical and safe tool to dismantle the swing shutters.

The simplicity of this concept leads to an attractive cost that becomes affordable for many purses.

The present invention consists of two light parts, portable and without wearing parts.

The first part consists of a lift quadrilateral which rests on four anchor points.

Its handling remains very easy in view of its lightness and its maneuverability for the tightening of what is similar to a clamp and which takes the form of a vice.

This quadrilateral is intended to be placed on the coping of a window.

This concept forms the first part of the device of the invention.

The second part takes the form of a gripper made up of two telescopic tubes held together by a tension spring.

Each end of the gripper receives a hook intended to securely retain the flap, by its shape and design.

A longitudinal handle is attached to the lower part of the gripper.

Whenever you want to hold a flap, the operator just has to hang the top of the gripper on the top of the flap and pull down to automatically hook the base of the flap.

This closing mechanism takes the form of a gripper that is as simple as it is efficient and secure.

The pressure between the telescopic tubes, exerted by the tension spring, allows the shutter to be firmly retained.

This gripper has several dimensions in the height direction, because the standard flaps generally measure 1.20m, but many have a height of 2.20m.

Each terminal equipment of the gripper takes the form of a conical trunk hook to maintain the different thicknesses of flaps.

The end of a lifting tube is articulated on the base of the gripper and ensures its maintenance

This lifting tube is oriented, articulated and slides on a pivot integral with the lifting quadrilateral.

It will be enough to press on the other end of this tube to lift the flap from its hinges, orient it facing the manipulator who will have to tilt the flap towards him thanks to the handle of the gripper.

A limit switch prevents the flap from tipping outwards.

The mechanism of this pivot allows the upward movement of the gripper and its descent thanks to the lifting tube on which it is supported.

In addition, this bar which takes the form of a lever slides in this slide secured to the pivot and its horizontal rotation device, which makes it possible to orient the gripper after de-bending or to position it for re-bending.

To unfasten or rewind the flap, the user holds the handle integral with the lower part of the gripper and with the other hand activates the handle of the lifting tube.

As a result, the user will easily lift the flap; rotate it in order to place it in the center of the window to immediately tilt it inward in order to house it intramural without risk, without difficulty.

Consequently, the manipulator can unhinge, orient and tilt the flap to introduce it intramural and envisage the opposite operation.

In conclusion, this lifting device comprises a telescopic gripper provided with a tension spring for closing it and with a gripping hook at each of its ends.

The lift quadrilateral, which rests on the coping, forms a secular point of support having in its upper part a rotary pivot allowing the operation of the lifting tube.

In one of the applications of the invention and without implied limitation:

Figure 1: The marks (1) (2) and (3) form the lever of the device intended to slide in both directions under the effect of the handle (1) in the slide (4) which is articulated on an axis (14) and whose horizontal rotation movement is allowed by the standard rotation device (6) Figure 3.

The reference (30) represents a swinging shutter.

It is retained by 2 hooks (28) and (29).

These hooks (28) and (29) remain integral with the telescopic tubes (27) and (31).

A tension spring (32) has the function of closing the gripper.

To enclose the flap in the gripper, simply place the hook (28) in the top of the flap when it is still on its hinges.

Immediately it is enough to exert a downward pressure on the handle (26) to hook the base of the flap which will be locked automatically under the effect of the spring (31).

The lifting tube (2) ends in the form of a reference square (39) and is articulated on the axis (23) retained by plates (22).

These plates (22) receive an axis (25) which is articulated on plates (24) and (33) integral with the tube (31).

The mark (20) is a limit switch which prevents the flap from leaning back.

The devices (21) and (22) serve as a guide during the inclination of the flap, preventing the gripper from tilting to the left or to the right.

The fixing of the handle (26) as well as the plates (24) and (33) are located at a certain height at the level of the tube (31) in order to grip the gripper at a height favorable for its handling.

The bracket (39) allows the attachment of this kinematic chain of lifting and orientation mentioned above.

Figure 2: The flap (30) is in a horizontal position after being unfolded and able to be tilted intramural.

To do this, the manipulator will remove the flap (30) in the direction of the hook (28) to release it from the gripper which will close immediately under the effect of the tension spring.

The plates (22) are in vertical position.

These plates (22) have rotated on the axis (23) which is articulated on the bracket (39).

The manipulation handle (1) and the end of the reference tube (2) and (39) have made a rotary movement of descent and ascent thanks to the articulation (14) in anticipation of an orientation movement.

Figure 3: This figure includes a rotating and pivoting concept.

The rotary concept is formed by a square tube (6).

This square tube (6) is designed to receive a longitudinal cylindrical tube (40), intended to allow favorable rotation.

This mark (40) is surmounted by a washer (7) to which it is integral.

The washer (7) is surmounted by a U-shaped pivot (8). This pivot (8) is designed to receive a second pivot (14) Figure 4, integral with a tube (41) Figure 4.

A tube (5), provided on either side with plates (11) and (12) is integral with the tube (6).

This tube (6) is crossed by a clamping device whose kinematic chain is similar to that of a clamp, formed by the pins (4), (9) and (10).

The mark (3) slides in the longitudinal direction on the tube (4), in order to better adapt to the different widths of the windows between the extra-muros facade and the intramural wall.

An adjustment device formed by the marks (1), (2) and (19) makes it possible to tighten the whole of this concept, for example a clamping vice or in accordance with the application of a legendary greenhouse -joint.

Figure 4: A longitudinal tube (15) with a lifting handle (1) receives a hole (16) at the other end.

This mark (16) is articulated on a gripper intended to retain a beating shutter.

The mark (14) is the pivot of the articulation, provided, for example, the pivot (7) in Figure 1, 5 with a hole for receiving a key.

This key allows the upward and downward orientation of the longitudinal tube (15) thanks to the handle (1).

The tube (15) receives holes such as (42), (17) and (18), intended to receive keys whose positioning serves as a longitudinal end-of-stroke device.

The cylinder (40), in addition to allowing rotation, remains removable by a simple upward movement of the lever (15).
