  The present invention relates to a removable device for protection against break-ins or breakage of windows, adapting from the interior of a room on windows and doors windows by taking support

  fixing between the opening and the frame.

  The effective protection of openings such as windows and doors against burglaries requires in most cases a system of grid or bars which leads to an expensive installation and work of piercing sealing and patching. Moreover, these types of protection can not

  be adaptable only on windows and although some models are aesthetically

  they often give a prison aspect to buildings that have them.

  On the other hand premises intended to receive the public include a number of openings that are intended to serve as emergency exits and therefore can not be equipped with such fixed installations. Other openings such as French doors can not receive fixed protection, and in the vast majority of cases buildings have no protection other than

  shutters or louvers that offer limited resistance to burglars.

  There are also a large number of buildings that have no protection of openings and on which the installation work of known effective means would lead to damage and recovery work.

masonry-and products.

  The present invention intends to overcome these disadvantages by providing a removable device for protection against theft and break glass by balloon projection or other object simply placed on the current joinery; the

  opening without transformation or adaptation work.

  For this purpose, the subject of the present invention is a device presenting itself

  in the form of a box frame whose bottom consists of a

  protection, grid, bars, armored glass or unbreakable synthetic glazing.

  According to an important characteristic of the invention, the device is

  easily accessible from the inside of the premises, which is of great use for the protection of secondary dwellings in unoccupied periods and

  in main house during departures on weekends or holidays.

  According to an advantageous embodiment of the invention, the frame is

  truit made of sheet steel and includes cut-outs to allow the

  dimensional tolerances of the frame.

  In an advantageous form of construction, the frame comprises

  handling equipment to facilitate installation.

  In another application of the invention, the device can be used in double protection and insulation windows, in this case the box will receive a

  unbreakable glazing and the walls of the box receiving insulation.

  In an alternative embodiment of the invention adapted to its use in the case of bays having one or more fixed doors, the device is made of at least two elements including at least one outer frame covering

  the total area of the bay and supporting the protection and a box according to the invention.

  the main frame to lock on the outer frame.

  Advantageously, the device is made of galvanized metal.

  In other finishing variants, the device may be coated

  color protection type paint or other similar coating.

  In a variant of construction the device according to the invention can

  be made of synthetic material.

  In a variant of construction the device according to the invention may comprise, in its part bearing against the frame, orifices intended to

to its possible fixation.

  In an advantageous variant of the invention, the device can

be equipped with a mosquito net.

  The invention will be better understood during the description given

  hereinafter only indicative and not limiting, which will allow to clear

  the advantages and secondary characteristics.
