Definitions

  • the present invention relates to a device for protecting an opening, comprising a first part and a second part, wherein the first part comprises a number of longitudinal bars located some distance apart and joined by a number of transverse bars in order to form a grating, the longitudinal bars being provided at one free end thereof with fixing means for fixing to the boundary of the opening, and which second part comprises a number of longitudinal bars corresponding to the number of longitudinal bars in the first part, wherein the free ends of the longitudinal bars of the second part are provided with fixing means for fixing to the boundary of the opening, the other free ends of the longitudinal bars of the first part and the other free ends of the longitudinal bars of the second part being designed so as slidably to accommodate one another.
  • a device of this type is generally known in the prior art and is described, for example, in US Patent 5 283 976.
  • This publication discloses a grating to be fitted in an opening such as a window, skylight and the like.
  • the longitudinal bars are arranged so as to be slidable into one another in order to provide for adjustment to openings of different dimensions.
  • locking means are provided in order to fix the longitudinal bars with respect to one another, after they have been slipped into a certain position, so as, in this way, to obtain a rigid construction.
  • the aim is to provide a device, for protecting an opening, which does not require locking means of this type and which can be of relatively lightweight construction, especially in respect of the fixing to the surrounding peripheral edge.
  • the invention is based on the insight that, as a result of the convex shape, when a load is applied from the "convex" side the longitudinal bars which are movable with respect to one another initially "jam together". On increasing the load, one part thereof is converted by the curved shape of the longitudinal bars into a force which is directed outwards, that is to say the free ends of the longitudinal bars are pushed against the peripheral boundary of the opening, as a result of which the grating according to the invention becomes jammed into the opening. Consequently, the fixing to the boundary edge of the opening can be of relatively lightweight construction. Moreover, as can be seen from the above, no retaining means are required in order to fix the longitudinal bars, which can be slid into one another, with respect to one another.
  • the device described above is preferably used in skylights and the like in which the convex shape is towards the outside. Especially in the case of skylights, the load exerted by, for example, burglars or other undesired persons will be directed downwards, with the result that the jamming effect is optimum.
  • the device according to the invention can likewise be used in a non-horizontal or even a vertical position.
  • the fixing for the longitudinal bars by one of their free ends can comprise any construction disclosed in the prior art.
  • the longitudinal bars are hingeably fixed at least on one side to the peripheral edge.
  • protection means which expose such screws in the non-functional position of the device according to the invention and conceal said screws in the functional position of said device. This is achieved in that the protection moves with the grating according to the invention.
  • the opposing free ends of the device according to the invention are preferably provided with retaining means which interact with the retaining means fitted to the peripheral edge of the opening. Locks or the like can optionally be provided to ensure that releasing can be carried out only by authorised persons.
  • the device according to the invention is indicated in its entirety by 1.
  • This device is designed to be fitted beneath a skylight 14 fitted in, for example, a flat roof.
  • Device 1 consists of a first part 2 and a second part 3.
  • the first part 2 consists of a number of spaced longitudinal bars 6 and joined by transverse bars 7.
  • the second part 3 consists of a number of longitudinal bars 5 arranged some distance apart and joined by transverse bars 15. It can be seen from the figures that the longitudinal bars 5 are able to slide into longitudinal bars 6 (see, in particular, Fig. 2). As a result of this slidability, it is possible to provide for optimum adjustment to openings of different widths.
  • the opening in which the device according to the invention is fitted is indicated by 4.
  • the boundary edge thereof is indicated on one side by 16 and on the other side by 17.
  • Edge 16 and part 2 are fixed by means of a hinge construction which will be explained in more detail with reference to Fig. 3.
  • transverse bar 9 is provided with openings or recesses 18.
  • Transverse bar 9 is hingeably fitted around a smaller inner bar 8.
  • the latter is likewise provided with openings 10 for, for example, fitting therethrough a screw 11, which can be firmly fixed into boundary edge 16.
  • recess 18 is not located in front of opening 10. That is to say, screw 11 is not accessible in the position shown in Fig. 3.
  • opening 18 will come to lie in front of opening 10 and screw 11 will become accessible.
  • the other free end of the grating is provided with a transverse bar 13.
  • Peripheral edge 17 is provided with a number of protruding lips 19 which are arranged on a common support 20, which can be fixed to edge 17 in any manner disclosed in the prior art. Lips 19 are provided with openings for accommodating therein locks 12 which are able to interact with plates arranged in longitudinal bar 13.
  • part 3 can be secured to boundary edge 17.
  • part 2 is fixed by some sort of retaining means to edge 17 and part 3 is hingeably mounted on edge 16.
  • FIG. 5 A further embodiment of the lock construction according to the invention is shown in Fig. 5.
  • the support is now indicated by 21, which support consists of an essentially flat plate provided on one side with openings 22 for accommodating screws 23 and provided on the other side with mushroom-shaped parts 24.
  • Said mushroom-shaped parts 24 consist of a pin 25 and an enlarged head 26.
  • transverse bar 13 is provided with openings 27 at the location of mushroom-shaped parts 24.
  • openings 27 are circular or somewhat elongated in the perpendicular direction, as is shown in Fig. 6.
  • a tube 28 is located inside transverse bar 13. This tube 28 is slidable and rotatable backwards and forwards with some play inside transverse bar 13.
  • tube 28 is provided with slots 29. These slots consist of a relatively narrow section 30 and a larger section 32. With this arrangement, head 26 is able to pass through the opening in the larger section 32, but not through the opening in narrower section 30. On the other hand, pin 25 is able to move both through the larger section 32 and through the narrower section 30.
  • a lock is arranged at the end of tube 28, which lock is shown diagrammatically and indicated by 33. The lock is provided with a cam 34 which can be moved inwards by means of the key and which engages behind the connection between transverse bar 13 and longitudinal bar 5.
  • the greater the longitudinal dimension of the opening the greater can be the radius of curvature of the grating because the effect of pushing outwards becomes greater.
  • retaining means which in the present invention are shown as lock means can be constructed in any other manner known from the prior art.
