A safety barrier, such as for children or pets and an extension section thereto

Abstract: A safety barrier, such as for children or pets, to be removable secured in apertures in buildings, e.g. doorways, staircases and windows, comprises an extension section (2a,2b) at least at one side of the barrier (1). The extension section (2a,2b) and barrier (1) having interlocking means for attaching the extension section to the barrier. The extension section (2a,2b) comprises a number of units (15), said units having at the top and bottom a longitudinal aperture (18) to accommodate a top and bottom assembly device (17,17a), that extends all the way through the number of units in question. The advantage is that extension sections (2a,2b) with different length could be made from a number of units (15) and due to the fact that the assembly device (17,17a) is in one piece makes the extension section itself and the complete barrier furnished with extension section very rigid.

Description: BACKGROUND OF THE INVENTION The Field of the Invention The invention relates to a safety barrier, such as for children or pets, to be removably secured in apertures in buildings, e.g. doorways, staircases and windows, said gate comprising an extension section at least at one side of the barrier, said extension section and barrier having interlopcking means for attaching the section to the barrier said barrier and extension section having a means at the top in the sides disposed to the aperture and a means at least at the bottom of the barrier for securing the gate and extension section in the aperture. Further the invention relates to an extension section to a safety barrier. The Prior Art To adapt safety barriers to fit specific apertures, it is known to equip such gates with threaded rods or similar devices in the corner, see e.g. US 5,396,732. Using lock nuts, these threaded rods can the n be adjusted so the safety barrier can be fitted and secured in the aperture in question. Threaded rods make it possible to vary the width of the gate within a limited interval. However, for security reasons the distance between the surroundings of the aperture such as a door-frame and the safety barrier, must not be too large, such that a child e.g. can squeeze its head through the passage. Moreover, a long unsupported threaded rod is not sufficiently rigid. This means that several standard gate widths are needed. One of the disadvantages of adjusting safety barriers using threaded rods is that the amount of adjustment possible is very limited. To obtain a larger adjustment extension sections of different width are used. The extension sections have studs, which fits into the holes used for the threaded rods. The threaded rods are then mounted at the end of the extension section facing the wall or frame. The benefit is that a standard barrier could be used. This however requires stock holding of extension sections of different widths. Placing such extension sections in continuation of each other renders the barrier unstable, since the addition of each new extension section results in an additional junction point, making the barrier increasingly unstable. From GB 2 219 026 is known a safety barrier having extension sections where the end of each extension tube is necked so that it is snug fitted in the respective free end of the barrier or the foregoing extension section. However this design is unstable due to a junction point between each extension section. At a different type of barriers consisting of two parts said barriers can be adjusted by displacing the two parts in relation to each other. The two parts are each longer than half the width of the passage and are assembled with overlying ends. Further, said barriers do not have its own frame, and is designed for attachment to a door frame or wall using screws or similar attachment systems. SUMMARY OF THE INVENTION The object of the invention is to provide a safety barrier that can be adjusted in width within a large interval, but with a minimum of junction points. At the same time, the safety barrier must retain the necessary rigidity and resistance to impact in sideways directions. The object of the invention is achieved by that the extension section comprises a plurality of units said units fitted at the top and bottom with a longitudinal aperture to accommodate a top and bottom assembly device that run all the way through the plurality of units in question. By means of the units various length of extension sections could be made using assembly devices of a corresponding length. As the assembly device runs all the way through the units the extension section appears very rigid. Making the units identical reduces stock holding even further but they could also be different to achieve a special appearance of the barrier. In an embodiment the length of the assembly devices may be less than the width of the number of extension units in question. The result is that the extension units are jammed between the securing means and the gate itself. In other words, the securing means sits tight against the outermost extension unit so that the extension units are fixed in position and cannot be moved. In a further embodiment the length of the assembly devices are longer than the width of the number of extension units in question. This ensures that the axial force on the top and bottom elements when the barrier is secured in the aperture is transmitted directly to the assembly devices. This is the best mode of ensuring correct attachment. The safety barrier with extension sections can be fitted with a control pin on one closing surface by the gate locking mechanism, with a hole designed to accommodate this control pin on the opposite closing surface. This control pin helps to increase the rigidity and resistance of the gate to impact at right angles. The assembly devices can be designed to ensure that standard securing devices to secure the gate fit into them. Designing the assembly devices in this way means that the standard fitting that normally belongs to the gate in question can also be used if extension sections need to be mounted on the gate, as described by the appended claims. BRIEF DESCRIPTION OF THE DRAWING The invention will be explained in detail below with reference to the accompanying drawing. In the drawing : Fig. 1 is a fully mounted safety barrier with extension sections, Fig. 2 is the same barrier before assembly, Fig. 3 is an enlarged detailed view of the locking mechanism, Fig. 4 is an enlarged detailed view of the upper part of the extension section to the left in Fig. 1, and Fig. 5 is an enlarged detailed view of the lower part of the extension section to the left in Fig. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The safety barrier shown in Fig. 1 and 2 consists of two main elements, namely a standard barrier 1 and an extension section 2a, 2b at either side thereof. The standard barrier comprises a rigid U-shaped frame 3 having a horizontally extending beam 4 and at either ends thereof a vertically extending pillar 5a, 5b. Further the barrier comprises an openable gate 6, said gate comprising an upper bar 7 and a lower bar 8 disposed in a parallel relationship. A plurality of spaced vertical extension rods 9 is disposed between the upper and the lower horizontal bars 7, 8. The gate 6 at one side hinged to the U-frame 3. One end of the lower horizontal bar 8 is hinged 10 to the upwards facing side of the horizontally beam 4 of the frame 3 and the corresponding end of the upper horizontal bar 7 is hinged 12 to a cap element 11 rigidly secured to the top of the neighbouring pillar 5b. The opposite top corner of the gate 6 is furnished with a locking mechanism 13 cooperating with a cap element 14 on the top of the respective pillar 5a. The horizontally extending beam 4 is preferably having a rectangular cross section placed edgeways. The pillars 5a, 5b are also having a rectangular cross section the width of which corresponds with the width of the beam 4 and welded or solded thereto. The horizontal bars 7, 8 of the gate 6 are having a square cross section and the bars 9 are having a circular cross section. The locking mechanism 13 and the hinges 10, 12 are not described in closer details as they are not part of the present invention but further information as to the nature of said parts could be found in US 5 396 732. An extension section 2a, 2b of different length could be made from units 15 comprising a top element 16a and a bottom element 16b and two identical assembly elements 17. The top and the bottom element 16a, 16b are having a horizontal through hole 18 into which the assembly element in the nature of a length of pipe could be inserted. The assembly element is having a square cross section which prevents the elements 16a, 16b from rotating and orientates the elements correctly. It is understood that the hole in the elements 16a, 16b is having a mating square cross section. Further the top and the bottom element 16a, 16b are having a vertically sleeve 19 with a hole 20 for accommodation of the end of a vertically rod 21 identical to the rods 9 in the gate. The end of the rod 21 is held by snug fitting in the sleeve 19. Alternatively the sleeve could be replaced by a knob and the end of a hollow rod being pressed over it. The length of the rod 21 is measured such that the top and the bottom element 16a, 16b will be in alignment with the upper rod 7 of the gate 6 the lower horizontal bar 4 of the U-shaped frame respectively. The underside of the bottom element 16b is having a fin 16c the edge of which is flush with the underside of the horizontal bar. When the barrier with the horizontal bar 4 is resting on a floor then the extension sections are also supported by the fins. The right hand side of the barrier 1 is furnished with an extension section 2a comprising one unit 15 only. The unit is placed against the barrier and an assembly device 17 is inserted into the top element 16a and pushed forward into a hole 22 in the cap 14 of the post 5a, said hole 22 being designed to receive the end of the assembly device 17 in a snug fitting manner. The length of the assembly device 17 is measured such that it terminates at the outer end of the hole 18 in the top element 16a and does not protrude from the element. The bottom element 16b is attached to the barrier 1 in a similar manner the assembly element 17 entering a hole 23 in a plug 24 inserted into the end of the horizontal beam 4, which is hollow. Into the ends of the assembly device 17 could be inserted a securing means 25 for securing the barrier with extension sections in a doorway, staircase or the like aperture. The securing means 25 comprises a threaded rod 26 bearing a foot member 27 at the outer end and a lock nut 28. The end of the threaded rod 26 could be inserted into the assembly device 17 and the lock nut 28 could be tightened against the front 29a, 29b of the top and bottom element respectively. The securing means is described in further details in US 5 396 732. It should be noted that the securing means 25 also could be used directly in connection with the standard barrier 1 as the securing means fits into two holes 22, 23 in the cap 14 on the pillar 5a and the horizontal beam 4 respectively, cp. Fig. 3. The other side of the barrier 1 is furnished with an extension section 2b comprising three units 15. The assembly device 17b is having a length 1 3 measured such that it goes through all three units. The end of the assembly units 17b is like before accommodated in a hole 22a in the cap 11 at the pillar 5b at the hinge side of the gate 6 and a hole 23a the end of the horizontal beam 4 of the frame. The assembly unit 17 is accommodated in the holes in a snug fitting of tight manner as described before. It would be understood that the assembly devices 17 are available in various lengths 1 1 , 1 2 , 1 3 matching a specific number of extension units 15 depending on the width of the extension section 2a, 2b required. As specifically shown in Fig. 2 one, two or three units. Using an assembly device 17 which as one piece runs through the units 15 makes the extension section very rigid and can resist perpendicular loads on the sides of the barrier or the extension section itself without lateral deflection which otherwise would make the securing means 25 loosening their contact with the surrounding aperture. Figure 3 shows details of the locking mechanism. The surface of the cap 14 facing the gate 1 is equipped with a control pin 30 that fits a hole 31 in part of the locking mechanism on the gate. This control pin 30 together with assembly devices 17, and the securing means 25, hinge 12 and locking mechanism 13 provides a safety barrier 1 having extension sections 2a, 2b with optimum rigidity. It would be understood that the present invention is not limited to the specific barrier shown in the drawing. The barrier could also be of the type with an openable gate at one side.
