In general, a safety device is known, that can be inserted into intrados of walls, for example in window or door openings and serve for people who they work in unfinished buildings not yet enter or fall to through the opening of the door and in this case rush to the empty, especially when such openings in the wall are provided on side walls of elevator boxes. In addition, such safety devices should contribute to not falling tools or construction material unexpectedly to through the opening of the wall and then injure people who they eventually work in the elevator boxes, which are occupied in the area of the wall openings.

It is known from GB 1 238 955 a security device, which has several locking elements, which can be inserted and supported between two wall elements. The Locking elements are connected to each other in the center area by means of longitudinal braces. Blocking element respective presents two support pieces, which are configured variables in length by means of a thread and are connected by force application with the wall elements in direction Longitudinal locking element.

It is known from document FR 1 332 639 A a blocking element, which is formed by two support pieces, which are variable both staggered and also through a screw provided at one end of a support piece. In addition to the union by application of force generated through the clamping, mandrels are provided on the wall surfaces, to through which the positive union is generated. They're not here provided other locking elements in the vertical direction in the blocking.

Accordingly, the problem of the invention consists of configuring and arranging a device to ensure openings in such a way that it can be inserted in a way simple and with sufficient tension in the openings.

The problem is solved, according to the invention, because at least two blocking elements that extend parallel each other are connected to each other by means of one or several longitudinal straps that extend vertically and at the same time the blocking element, connected through the braces longitudinal, it can be extended through the rotation of the blocking element around the longitudinal axis, whereby the positive and / or union element by force application is You can press against the support surfaces. Through advantageous configuration of the variable configured blocking element in length, which can be fixedly connected with opposite parts from the wall of a wall opening through joining elements positive and / or binding by force application, can be inserted and secure these elements in these openings in a while relatively short, so that they are not variable already in their position in the case of higher load and thus guarantee that people working in the area of the opening are protected and prevent them from accessing inadvertently through these openings, especially when such openings are provided in the area of ditches or elevator boxes. Also, through this device that can be easily mounted ensures that it can be Always insert into wall openings to be closed, being in this case advantageous that the cost of assembly time is very reduced. Since the device consists of several elements of lock, can be adapted to openings of different sizes without problems. To this end, the variable configuration also contributes to the length of the blocking elements.

Additionally, it is advantageous that in addition to a first blocking element, at least one second is provided variable locking element in length, arranged at a distance thereof, being inserted between the blocking elements a large surface lock piece. Through the employment of several blocking elements that are adjacent to each other and to through the use of large surface locking parts, which they can connect with the locking elements detachably, relatively large surface openings can be closed in buildings without problems in a very short time.

According to a device development according to the invention, another possibility is that the elements Locking, extending parallel to each other, the braces longitudinal as well as the locking piece form a device of lock that closes at least partially the opening (1) and that You can rest on at least one floor of the building.

In another configuration of the invention, it is advantageous that the locking part is flexibly configured and / or transparent. Through the use of a locking piece configured flexible and also transparent, this can be used in everywhere and can also be preserved after the assembly of new saving space, since the lock piece configured in a flexible way it can be accommodated without problems on a space minimum. The locking piece can be configured for this purpose as fine mesh or coarse mesh network and guarantees that they cannot get tools inadvertently through openings From the wall.

Finally, according to a form of preferred embodiment of the invention, it is provided that the piece of lock is fixedly connected and removable with the blocking elements and / or with longitudinal braces. Through of the removable union of the longitudinal braces with the locking elements can be easily mounted and can be adapt to any desired size of a wall opening. If not the locking device for the opening of the wall is already needed, it can be disassembled and can be accommodated in a minimum space and can transport. In this way, it is possible without problems the multiple use of locking devices of this type, since which can be adjusted according to the needs to size correspondent.

In connection with the configuration and layout  according to the invention, it is advantageous that two or more locking pieces are arranged parallel and at a distance from each other, being connected in each case two fixed and shaped locking parts removable with a respective locking element and / or with the opposite longitudinal straps.

In addition, it is advantageous that because the elements of positive union and / or union by force application configured as a U-shaped fixing bracket, being the mounting bracket arms are configured in a variable way the length. Since the joining elements by application of force are configured as U-shaped fixing bracket, these can be placed without problems on the front edges of intrados of walls or wall elements in positive connection or by force application and thus ensure the device of lock in the wall opening.

To this end, it is advantageous that the device lock can be tied in a wall opening and can be rest on the ground through the longitudinal braces and it has at least two fixing brackets open upwards, arranged at a distance from each other, in which they can be inserted the flat cross pieces. Through the use of flat configured cross pieces, which may be also configured as tables, an insurance is additionally created, especially in the base area of the locking device. This prevents in the same way as mainly the components small, which are on the ground, can be pushed unnoticed way beyond the opening and can then fall to empty.

Other advantages and details of the invention are represented in the patent claims and explained in the description and are represented in the figures. In this case:

Figure 1 shows a locking device in the view from the front, which is inserted into an opening of a wall.

Figure 2 shows a side view of the locking device according to figure 1.

Figure 3 shows a door strut individual locking device in the view from above or well in a section along the A-A line ' according to figure 1.

Figure 4 shows a view of the strap transverse or of the locking element in the front view according to figure 3.

Figure 5 shows a detailed representation of the locking element configured as a door strut according to the Figures 3 and 4.

In the drawing, in figure 1 it is designated with a 15 blocking device, which is essentially constituted by the minus two blocking elements 3, 8 and 9 that extend parallel each other, which can be connected, respectively, on the side end in opposite longitudinal struts 11, placed at an angle straight to each other. As it is especially deduced from the figure 1, between blocking elements 3, 8 and 9 as well as between longitudinal struts 11 individual is a piece of lock 10, which is configured, in the embodiment according to Figure 1, as a piece of elastic net, which is connected in a manner removable on its front edges with locking elements 3, 8, 9 and longitudinal braces 11. Instead of the net piece, the locking piece 10 can also be configured as a piece of transparent, tear-resistant plastic, for example you can insert plexiglas, awning, sheet, fabric between the elements of lock 3, 8 and 9 as well as between longitudinal braces 11.

An essential component of the locking device 11 is formed by blocking elements 2 and 8 variables in the length, which can also be used as door struts. A locking element 3 or 8 of this type is illustrated in detail in Figures 3, 4 and 5. The blocking element 3 is constituted by a first support piece 18 configured as a tie rod tubular, in which a second is scrollable support piece 19 configured as a tubular shaped brace. He tie 3 can be tied in numerous positions within the first support piece 18. To this end, the two support pieces 18, 19 they have numerous holes 20, which can be taken to coincidence with each other and serve to accommodate a bolt 24, so that the locking element 3 is adjustable to lengths of different size.

On pivot 3.1 it is coupled, as shown in Figures 1 and 2, the longitudinal strap 11, to constitute of this way the blocking elements 3 superimposed and close the opening 1 up. The blocking element 8 has, according to the Figure 2, a positive and / or union element by application force 7 with an upper pivot and a lower pivot 7.1.

It is also possible, according to another example of implementation, configure the longitudinal braces 11 as positive and / or union elements by force application 7 U-shaped, shown in Figure 5, which can be placed, according to figure 5, on the front surface or the surface of support 4 of the wall element 2.

The surface of the opening, provided between longitudinal braces 11 and locking elements 3, 8 that extend transversely to them, it can be closed through the another locking piece 10. The locking piece 10 is configured as a narrow mesh network, which is detachably attached to through connecting elements 25 or with the blocking elements 3, 8 and 9 and / or with longitudinal braces 11.

In addition to the locking elements 3, 8, 9, it they can provide especially in the lower area of the device lock 15 flat cross pieces 17, which may be configured, for example, also as wooden boards. The pieces transverse 17 can be fixedly fixed or removable with longitudinal braces 11.

According to figure 2, the two braces longitudinal 11 opposite have fixing brackets 16 in Angle shape, open in such an upward direction, in which they insert the transverse pieces 17 from above and are secured by means of nails or screws. The cross pieces secure in the lower area of the locking device 15 than the components that they are, for example, on the ground, they are not introduced without more through the opening 1 and thus fall into the box to insure and injure in this case, for example, workers, who They are working on the box.

In the exemplary embodiment according to figure 4, represents how the blocking element 8 is inserted between the two opposite surfaces 4 of the wall elements 2. To such Finally, the second support piece 19 is fitted first in the first support piece 18, so that the entire locking element 8 can be inserted between the two supporting surfaces 4 opposite of the wall elements 2. Then the two are placed positive and / or union elements by force application 7 on the front surface of the two opposite wall elements 2 and then and removes the second support piece 19 out of the first support piece 18 until the positive joint element and / or joining by force application 7 rests firmly against the support surfaces 4. But now the bolt can be inserted, identified with 24 in figure 4, in two holes 20 superimposed to flap and in this way the second brace 19 can be secured in the desired position, so that it cannot be modified anymore the position of the blocking element 8 and therefore serves as security element. To guarantee a clamping force Improved positive bonding element and / or bonding by application of force 7 against the bearing surface 4, the rod 21 configured as threaded rod from the second piece of support 19 until the locking element 3 acts with force of press sufficiently against the support surface 4. The insert or fixing of the remaining blocking elements is done in a Similarly. Since the locking piece 10 according to figure 1 It is configured as a network piece, it can also be adapted without problems to openings of different sizes. To that end, the piece lock 10 is elastically configured, but in such a way that offers sufficient protection for operators and prevents these enter inadvertently through opening 1.
