Description

Lifting device according to the principle of the lever for removing or replacing window shutters in their hinges

The device of the invention replaces the muscles of a manipulator whenever it applies to remove or replace a window flap housed in its hinges

This painful and expensive work is necessary during repairs or replacements or new installations of shutters.

This kind of activity is widespread in the world because most properties are equipped with window shutters.

The maintenance of these shutters is required periodically for the purposes of interviews and painting which gives value to the elegance of homes.

To remove a window flap from its hinges this is a handling problem because the weight of the flap often exceeds the strength of the handler.

As a general rule at the level of the buildings this service is carried out during the facelifts by using the scaffoldings already installed.

The problem is quite different in the individual houses because the cost of the intervention remains very important

In this case, a hoist is needed because it is not compatible with specialized and expensive handlers.

This type of service remains very expensive because of the burden of the workers and their equipment.

As a result, property owners have to bear the disadvantages of this service because of its cost.

An obvious fact is that everyone, homeowners or tenants would like to give color to its shutters but it seems like mission impossible because too expensive.

But the repair or painting or maintenance service is within the reach of everyone whenever a window shutter will be available housed on trestles for example after dismantling.

The device of the invention provides the perfect solution pleasant, easy, inexpensive, without difficulty and without the slightest risk of accident to remove or replace a window pane in its hinges. The use of the device of the invention remains very simple.

Specifically to the Board: 1- Figure: 1, a telescopic tube (1) fits perfectly between the top and the base of a standard window frame.

A handle (26): Plate: 2- Figure: 2, formed by a metal rod (9) is articulated on a fulcrum (17) housed in a support (16).

This support (16) is held in a telescopic arm (13) and (29) integral with the telescopic tube (1) Plate 3- Figure (3). With the Board: 2 - Figure 2, the end of a telescopic rod (22) and (27) has the property of trapping the shutter under the action of a holding and locking handle (21).

The base of this telescopic tube (27) and (22) is articulated on the end (20) of the rod (9) which forms the lever. The other end receives a handle. (26)

Consequently, the user of the device of the invention exerts a pressure upwardly on the handle (26) to lift the telescopic tube (27) and (22) which traps the shutter after housing the piston (16) which oriented in the telescopic arm (13) and (29) integral with the telescopic piston (1) previously housed in the frame of a window.

Very precisely: Plate 3 - Figure 3, the marks (1) and (2) form the telescopic piston by manual rotation and flexible vertically housed between the upper part and the lower part of a window frame.

A bracket (32) receives flanges such that (33) has an axis (31) and a limit switch (30) on which are oriented from left to right the telescopic arms (29) and (13) ) whose linear movement is regulated by the piston (15) in the housings (28).

In the application of the invention the plate (4) is hinged to perfectly marry the slanted shape of the window frame.

The plate (3) is articulated on a pivot (8) for a horizontal rotation of the cylinder (2) and finally to modify the linear stroke of the pistons (2) and (1).

This articulation makes it possible to turn the cylinder (2) to the left or to the right according to which it is desired to modify the height of the assembly of this telescopic piston formed by the marks (2) and (1).

A threaded rod (6) integral with a piston (5) receives a nut (7) integral with the cylinder (2).

Whenever a left or right manual rotary movement is exerted on the piston (2), the height of the assembly will be changed.

In one of the applications of the invention the pistons (1) and (2) are housed horizontally and as previously outside the window.

A cylinder (36) supports the bracket (32) to allow rotational movement such as (14).

The upward movement such as (11) is obtained thanks to the movement of the lever (9) whose limit of travel is limited by the mark (19).

The mark (30) is the end of travel of the arm (29) which allows its horizontality and under these conditions a better consideration of the shutter.

The lever arm (9) pivots on the axis (17)

Its end (18) is articulated in the part (20) to allow the upward movement or descent of the steerable arms (22) and (27) previously pressed against a window shutter

This piece (20) is articulated on a pivot (18) and thus allows the upward movement of the telescopic tube (27) and (22).

The ends of the tubes (22) and (27) receive hooks (24) and (23) whose property is to trap the shutter

The capacity of the tubes (22) and (27) makes it possible to retain standard shutters of any size.

Whenever there is a difference in the shutter height this leads to an identical window frame.

The product of the invention provides the entire solution in the difference in level obtained by the rotation of the piston (2) inside the piston (1) with the threaded pin mark (6).

Still more specifically as an indication and not limitation: Plate 3- Figure 3, the marks (3) and (4) are stabilizers for pressing at the top and bottom of a window frame, each time placed at the top and bottom of the window frame or in another application horizontally in the same frame.

The tube (2) slides in the tube (1) by means of the nut (7) whenever a rotation is made to the piston (2).

This linear movement is achieved by the rotation of the tube (2) which holds a nut (7), intended to rotate in the threaded rod (6).

This threaded rod is secured to the tube (1) thanks to the cylinder (5).

The cylinder base (1) is integral with the plate (4).

A piston (12) receives a telescopic arm (29).

This telescopic arm (29) slides in a receiving arm (13) with bore (28) and a stopper (15). The end of the receiving arm (13) receives the small diameter of a cylinder (10) surmounted by another larger cylinder (16) which is articulated on an axis (17).

On the axis (17) articulates the lever (9) with its handle (26).

The marks (13) and (29) make it possible to modify the length of the arm as a function of the demand imposed by the width of the flap.

This allows positioning the device (27) and (22) in the center of the flap in order to avoid any risk of inclination that would result from a poor consideration.
