Description

- 2 -

The present invention relates to the use of cavities for the safety of living beings, valuables, mohilms, real estate, etc.

The cavities consist of assembled individual parts 5 and töü & MKMKäKK hollow profiles of any shape (round, rectangular ..)

The example given here is a construction with a "dog profile (steel tube). This can be welded, screwed, glued or assembled using a thread.

Io In new prisons it has been proven that too

Safety glass smashes Vierden without anyone noticing. The same uncertainty applies to the well-known grille from "VOI L-PROFII, -STAHL". This could often be cut unnoticed by a saw, a bearing.

15 In my invention, this is no longer possible.

The purpose of my invention is that one uses the cavity for security. This goal is achieved by the construction according to the invention Fig.I, from which it can be seen that the actual security in the use of the cavity 2o (pipe grid) and not as before, in Full material lies.

The construction according to the invention is essentially characterized by the following 5 points * 1. Cavity (pipe grid, etc.) 2. Pressure regulator 25 3 · inlet and outlet valve 4. Independent power source (battery) 5. Alarm system (siren, bell, flashing lamp, etc.)

The advantages of this invention are * 1. In that the lattice consists of a cavity.

\ I

3o (communicating vessels) is the same pressure everywhere.

2. If you hear, saw, etc. at any point on the hollow grille, this only goes until you reach the cavity, that is, you can only penetrate a few millimeters into the material.

s 35 3 «If you get to the cavity, the pressure in the

Hollow mesh and an alarm is triggered.

-1 4th .This lattice construction is much lighter than the old one.

It is also much cheaper and above all much safer] Furthermore, it can also be installed anywhere, at a later date, easily and inexpensively.

5. 5. Damaged files can easily be removed and replace Vierden.

6. A damaged part can also be welded there (e.g. saw slot).

7 · In detail, the advantages of the drawing Fig.I,

Io can be seen. Fig.2, represents only a view of the

Hollow grille, from below, in a crest (wall). You can also see in Fig ^. ’VA" that it is a tubular grille · ,, ·

Claims (3)

5 real estate etc. serve and which in particular takes advantage of the principle of communicating vessels. b) An overpressure or a negative pressure is generated in the construction - via the inlet / outlet valve "G". c) The construction consists of s see Fig. I. Io i.A closed cavity "A". (Pipe grid) 2.A pressure regulator "B". 3 «An inlet and outlet valve" C ". 4 «An alarm system" B ". 5. An independent power source "E". 15 6.Electric cable "F". 7. A closed space "G * (for" C "and" B ") 8. Frame MH "'(for inserting MA") 9.Socket "J" (on which "C" is attached) Io.Socket "K" (on which "B" is attached) 2o The space "G" must not necessarily above the grid "A". In this case, a connection from "K" to "B" and from "J" to "C" must be made in the more distant space "G" (communicating vessels) Connect 0 ** to "K". "J" is then superfluous and is closed. (Like the other pipe grille ends 25 d) Function of the construction * i) For the whole thing to work, the points i-Io must be as in Fig. I can be seen, assembled. Ii) If a saw falls or increases the pressure in the cavity "A". 3o iii) Via the pressure regulator "B", the electrical cable "F" <() the power source ,, E ", the alarm system" D "is now put into operation. The alarm system" D "can be installed anywhere and can produce both a noticeable and a silent alarm. trigger. 35 e) This principle of using the cavity can be used everywhere. For example * for safety doors in banks etc. It only ever changes the shape of the cavity.
