Description

[0001] The invention relates to a barrier field for a barrier, such as a stair railing, a fence railing or a safety railing, comprising a first strut, a second strut and at least one rod.

[0002] Barrier panels are known from the prior art in which the bars are firmly connected to the first strut and the second strut. For example, it is common practice for stair railings to have a first upper strut and a second lower strut, to which a plurality of vertical bars are welded. Alternatively or additionally, the vertical bars can be connected to the struts with screws, rivets, or nails.

[0003] However, the disadvantage of conventional stair railings is that they are only adapted to a specific, predefined gradient, which is determined by the angle of the connection between the struts and the rods. This makes it impossible to adjust the stair railing or its gradient, so the railing must be assembled on site. The same applies to conventional fence railings or safety railings.

[0004] The present invention is therefore based on the object of developing a barrier field of the type mentioned at the outset in such a way that the barrier field can be adapted to the conditions of the site of use, in particular with regard to the gradient.

[0005] This object is achieved by a barrier field according to claim 1 and a barrier according to claim 10 as well as an articulated connection according to claim 12. Further advantageous developments of the barrier field according to the invention and the barrier are specified in the dependent claims.

[0006] According to a first aspect of the present invention, a barrier field is proposed. The barrier field comprises a first strut, a second strut, and at least one bar.

[0007] According to the invention, it is now proposed that the barrier field further comprises at least one articulated connection, wherein the at least one articulated connection connects the at least one rod to the first strut or to the second strut in an articulated manner.

[0008] Within the meaning of the present invention, a barrier can be a fence, i.e., a structural device that prevents people and / or objects from falling from lower surfaces. A barrier according to the invention can, for example, be a stair railing and / or a fall protection railing. Alternatively or additionally, a barrier within the meaning of the present invention can be a structural device that divides an area without a slope, such as a meadow. In this context, a barrier according to the invention can be a fence railing.

[0009] A barrier field in the sense of the present invention can be a railing field and / or a fence field.

[0010] The barrier field comprises two struts, a first strut and a second strut, which can be oriented horizontally (parallel to the surface slope or gradient) or vertically with respect to the area delimited by the barrier. Thus, a first upper strut and a second lower strut, or a first lateral strut and a second lateral strut, can be provided.

[0011] At least one rod connects the first strut to the second strut, wherein the at least one rod is connected to the first strut or to the second strut via the at least one joint connection. The at least one rod can be oriented horizontally (parallel to the surface inclination or gradient) or vertically.

[0012] By means of the at least one articulated connection, different inclinations of the at least one rod relative to the first strut or the second strut can be set.

[0013] The barrier field according to the first aspect of the present invention therefore has a certain adjustability for installation, so that the barrier field can be adapted to different gradients of the ground or surface.

[0014] The need to assemble the barrier on-site or to custom-make it is eliminated. This has the advantage that a standardized, prefabricated barrier panel can be attached to a barrier or its frame in just a few simple and straightforward steps, regardless of the gradient the barrier panel must accommodate.

[0015] A further advantage is that the barrier panel according to the first aspect of the present invention can be used on substrates or surfaces with different slopes. For example, if several barrier panels are to be installed at locations with different slopes in a project, there is no need to provide and deliver corresponding custom-made barrier panels for specific locations, because the barrier panels according to the invention can be installed at any location, regardless of the slope there.

[0016] According to one embodiment, the barrier field further comprises a further articulated connection, wherein the at least one articulated connection connects the at least one rod to the first strut or to the second strut, and the further articulated connection connects the at least one rod to the second strut or to the first strut. By means of the at least one articulated connection and the further articulated connection, the at least one rod is articulated to both the first strut and the second strut. This has the advantage that both the angle between one end of the rod and the first strut and the angle between the other end of the rod and the second strut can be adapted to the circumstances. This further improves the adaptability of the barrier field, enabling better adaptation to different inclinations of the ground and expanding the usability of the barrier field.

[0017] According to the invention, the barrier field can comprise a plurality of bars connecting the first strut to the second strut, with at least one hinged connection being provided for each bar, connecting the respective bar to the first strut or to the second strut. The presence of a plurality of bars allows the barrier field to have greater stability and cover a larger area.

[0032] Preferably, the possible angle can be greater than 130°.

[0033] Preferably, the possible angle can be greater than 140°.

[0034] Preferably, the possible angle can be greater than 150°.

[0035] Preferably, the possible angle can be greater than 160°.

[0036] Preferably, the possible angle can be greater than 170°.

[0037] Preferably, the possible angle can be less than 180°.

[0038] Preferably, the possible angle can be less than 170°.

[0039] Preferably, the possible angle can be less than 160°.

[0040] Preferably, the possible angle can be less than 160°.

[0041] Preferably, the possible angle can be less than 150°.

[0042] Preferably, the possible angle can be less than 140°.

[0043] Preferably, the possible angle can be less than 130°.

[0044] Preferably, the possible angle can be less than 120°.

[0045] Preferably, the possible angle can be less than 110°.

[0046] Preferably, the possible angle can be less than 100°.

[0048] Preferably, the possible angle can be less than 80°.

[0049] Preferably, the possible angle can be less than 70°.

[0050] Preferably, the possible angle can be less than 60°.

[0051] Preferably, the possible angle can be less than 50°.

[0052] Preferably, the possible angle can be less than 40°.

[0053] This allows the barrier field to be adapted for different surface inclinations or for different inclinations.

[0055] For example, it can be provided that the barrier field has at least two bars, each of the at least two bars being connected to the first strut and to the second strut via a respective articulated connection, the first bar connecting a first end of the first strut to a first end of the second strut, and the second bar connecting a second end of the first strut to a second end of the second strut. The barrier field can thus be designed as a frame, in which case it is preferably provided that further bars are present, each of the further bars being connected to the first strut or to the second strut via at least one articulated connection.

[0056] Further preferably, it can be provided that for each rod there is at least one articulated connection and a further articulated connection, wherein the at least one articulated connection connects the rod to the first strut or to the second strut and the further articulated connection connects the rod to the second strut or to the first strut.

In the embodiment according to the Fig. 6 the first strut 102 and the second strut 104 are arranged perpendicular to the third strut 164 and to the fourth strut.

[0126] The barrier 150 has a barrier frame 152, which includes a crossbar 154 and two lateral bars 156. The lateral bars 156 are firmly connected to opposite ends 158, 160 of the crossbar 154 by means of webs 162.

[0127] The barrier 150 further comprises a barrier field 100 which, in contrast to the barrier field 100 according to Fig. 1 a third strut 164 and a fourth strut 166, wherein the third strut 164 connects a first end 170 of the first strut 102 to a first end 172 of the second strut 104 and the fourth strut 166 connects a second end 174 of the first strut 102 to a second end 176 of the second strut 104.

[0128] The barrier field 100 is attached to the side bars 156 of the barrier 150 by means of connecting elements 168.

[0129] In the embodiment according to Fig. 6 the first part 112 and the second part 114 of the articulated connections 108, 110 are arranged coaxially to each other.

[0130] Fig. 7 shows a further embodiment of a barrier 150 according to the invention. The barrier 150 of the embodiment according to Fig. 7 differs from the barrier 150 according to the embodiment of the Fig. 6 in that the barrier 150 in the embodiment according to Fig. 7 comprises or is a stair railing for a staircase 178. In the embodiment according to the Fig. 7 Thus, the first strut 102 and the second strut 104 are not arranged perpendicular to the third strut 164 and the fourth strut.

[0131] Fig. 8 shows another embodiment of a barrier 150 according to the present invention. The barrier 150 according to

[0132] Fig. 8 comprises or is a stair railing for a staircase 178. In contrast to the embodiment according to Fig. 7 the barrier field 100 of the Fig. 8 a first frame bar 180 and a second frame bar 182.

[0133] The first frame bar 180 connects the first end 170 of the first strut 102 to the first end 172 of the second strut 104. For this purpose, two articulated connections are provided, wherein a first articulated connection 194 connects an upper end 186 of the first frame bar 180 to the first end 170 of the first strut 102 and a second articulated connection 196 connects a lower end 188 of the first frame bar 180 to the first end 172 of the second strut 104.

[0134] The second frame bar 182 connects the second end 174 of the first strut 102 to the second end 174 of the second strut 104. For this purpose, two articulated connections are provided, wherein a third articulated connection 198 connects an upper end 190 of the second frame bar 182 to the second end 174 of the first strut 102 and a fourth articulated connection 200 connects a lower end 192 of the second frame bar 182 to the first end 172 of the second strut 104. In the embodiment according to the Fig. 8 the first frame bar 180 and the second frame bar 182 are not arranged perpendicular to the first strut 102 and the second strut 104.

[0135] In Fig. 8 All joints 194, 196, 198 and 200 have the same design.

[0136] The Fig. 9 bis 11 show a possible embodiment of the joint connection 194, 196, 198 and 200. In the Fig. 9 bis 11 Reference is made to the first joint connection 194 as an example.

[0137] The first articulated connection 194 differs from the articulated connections 108, 110 in that the first articulated connection 194 does not have a fastening device 134 and a receptacle 132. Instead, both the first part 112 and the second part 114 have a locking lug 202 with a clamping part 204, wherein the locking lug 202 with the clamping part 204 is designed to be received in a corresponding receptacle, not shown in detail here, of the first strut 102 or the first frame bar 180. This creates a locking or clamping connection between the first articulated connection 194 and the first strut 102 or between the first articulated connection 194 and the first frame bar 180. Such a locking or clamping connection provides the barrier field 100 of the Fig. 8 a high level of stability and strength and also allows for better adjustability and adaptability to different surface inclinations or gradients, so that the barrier field 100 of the Fig. 8 has a wider range of applications.

[0138] The first part 112 and the second part 114 of the first joint connection 194 according to Fig. 9 lie in a plane of rotation and enclose a right angle α. The angle α can have any value between 30° and 180°.

[0139] Fig. 10 shows a detailed sectional view of the first joint connection 194 according to the embodiment of the Fig. 9 along lines AA from Fig. 9 . As in Fig. 10 As shown, the clamping part 204 is pressed into a cavity 206 of the locking lug 202. The cavity 206 is delimited by an outer wall 208, which has an inner cavity surface 209 extending from an outer surface 210 of the locking lug 202 to a surface 212 of the second part 114. The cavity 206 has a shape that tapers towards the surface 212. The clamping part 204 has an outer surface 205 that tapers from a first clamping part end 201 to a second clamping part end 203. Furthermore, both the second part 114 and the clamping part 204 have a bore 214a, 214b. The bores 214a, 214b are formed or arranged coaxially to one another.

[0140] A nut receptacle 216 is provided in the clamping part 204, in which a nut (not shown in detail here) is received. A clamping screw (not shown in detail here) with a screw head can be inserted into the bore 214a, 214b such that the screw head is received in the screw head receptacle 218. The clamping screw is then screwed into the nut, so that the clamping part 204 is at least partially received in the cavity 206.

[0141] The second part 114 with the locking lug 202 and the clamping part 204 can then be connected to the first end 170 of the first strut 102 by receiving the locking lug 202 into a locking receptacle (not shown in detail here) of the first strut 102. The clamping screw can then be screwed further into the nut so that the clamping part 204 is drawn into the cavity 206. As a result, the outer wall 208 of the locking lug 202 is spread outward by the clamping part 204, creating a clamping connection between the second part 114 of the first joint connection 194 and the first strut 102.

[0142] This ensures greater stability and strength of the connection between the first strut 102 and the second part 114 of the first joint connection 194.

[0143] The first part 112 of the first joint 194 can be connected to the upper end 186 of the first frame bar 180 in a similar manner to the second part 114 of the first joint 194 being connected to the first end 170 of the first strut 102. This can ensure greater stability and strength of the connection between the first frame bar 180 and the first part 114 of the first joint 194.

[0144] Finally, the first part 112 of the first joint 194 can be connected to the second part 114 of the first joint 194 by means of a connecting screw 220 with a screw head 221 inserted into the bores 126, 128, onto whose shaft the nut 122 is screwed. The nut 122 is received in the countersunk hole 130 of the first part 112 of the first joint 194. The screw head 221 of the connecting screw 220 is received in the countersunk hole 130 of the second part 114 of the first joint 194.

[0145] The barrier 100 with the first joint connection 194 therefore has greater stability and strength.

[0146] Fig. 11 shows a view of the first joint connection 194 according to the embodiment of Fig. 9 , wherein the first part 112 and the second part 114 lie in the plane of rotation and enclose an acute or sharp angle α. The angle α is in the embodiment according to Fig. 11 30°. The angle α can be between 30° and 180°, so the angle α does not necessarily have to be an acute or sharp angle.

[0147] The one in the Fig. 9 bis 11 The articulated connection shown can also be used as an articulated connection for connecting the rod 106 to the first strut 102 and / or to the second strut 104.

[0148] Fig. 12 shows a possible embodiment of a barrier field 100 according to the Fig. 8 , wherein the first frame bar 180 and the second frame bar 182 are arranged perpendicular to the first strut 102 and to the second strut 104.

[0149] Fig. 13 shows an alternative embodiment of a barrier panel 100 according to the present invention. The barrier panel 100 includes a first frame stay 180, a first strut 102, and a second strut 104. The upper end 186 of the first frame bar 180 is connected to the first end 170 of the first strut 102 via the first hinge connection 194. The lower end 188 of the first frame bar 180 is connected to the first end 172 of the second strut 104 via the second hinge connection 196. A plurality of bars 106 connect the first strut 102 to the second strut via hinge connections 108, 110.

[0150] The embodiment according to the Fig. 13 is advantageous in that the angle between the first strut 102 and the first frame bar 180 or the angle between the second strut 104 and the first frame bar 180 can be adjusted so that the barrier field 100 can be better adapted to the terrain on which it is used. The barrier field 100 according to the Fig. 13 is therefore more flexible to use than, for example, the barrier 150 according to the Fig. 7 , 8 or 12 .

[0151] Fig. 14 bis 17 show alternative embodiments for a joint connection, wherein Fig. 16 a sectional view along the line AA of the Fig. 14 represents.

[0152] The first part 112 and the second part 114 each have a locking lug 202.

[0153] The joint 222 according to the Fig. 14 bis 17 has a first part 112 and a second part 114. The first part 112 and the second part 114 are articulated to each other by means of the connecting screw 220 and the nut 122. For this purpose, the connecting screw 220 with the screw head 221 is inserted into the bores 126, 128. The nut 122 is received in the countersink 130 of the first part 112 and the screw head 221 is received in the countersink 130 of the second part 114. The angle α between the first part 112 and the second part 114 can be between 30° and 180°, wherein in the Fig. 14 It is shown that the angle α is 90°.

[0154] The first part 112 and the second part 114 of the articulated connection 222 have locking lugs 202 with spring clips 224. For the description of the spring clip 224, reference is made to the spring clip 224 of the first part 112 as an example.

[0155] The spring clamp 224 is received in a groove 223 of a blind rivet nut 225, which is provided with a spring clamp screw 226 with a screw head 228. The screw head 228 is received in a countersunk hole 230 of the first part 114, and the screw 228 is received in a bore 232 of the first part 114.

[0156] When the spring clamp screw 226 is rotated, the spring clamp 224 can be pulled toward the surface 210 of the locking lug 202 so that the spring clamp leaves 234 of the spring clamp 224 are pressed onto the surface 210 and spread outward.

[0157] Thus, the first part 112 of the articulated connection 222 can be connected to a first strut 102, a second strut, a first frame bar 180, a second frame bar 182, or a bar 106 by inserting the locking lug 202 into a receptacle provided for this purpose. The spring clamp screw 226 is then rotated so that the spring clamp leaves 234 are pressed onto the surface 210 of the locking lug 202 and spread outward. The outward spreading of the spring clamp leaves 236 presses them against an inner wall of the receptacle in which the locking lug 202 is received. This creates a clamped connection.

[0158] The second part 114 can be connected in a similar manner to a first strut 102, a second strut, a first frame bar 180, a second frame bar 182 or to a bar 106.

[0159] As a final step, the first part 112 and the second part 114 of the joint 222 can be connected to each other by the connecting screw 220 and the nut 122 and the angle α between the first part 112 and the second part 114 can be adjusted as desired.

[0160] Fig. 18 und 19 show the joint connection 222 according to the Fig. 14 bis 17 in two different positions. In the position according to the Fig. 18 the angle α is 30°. In the position according to the Fig. 19 an angle α', which is defined as the difference between a full angle and the angle α, is 225°, so that the angle α according to the Fig. 19 is 135°.

[0161] Fig. 20 bis 27 show a slightly modified embodiment of a joint connection 236.

[0162] The Fig. 20 bis 23 show the joint connection 236 with the first part 112 and the second part 114, wherein the angle α between the first part 112 and the second part 114 is 135°. Fig. 22 shows a sectional view along the line AA of the Fig. 20 .

[0163] The Fig. 24 bis 27 show the joint connection 236 with the first part 112 and the second part 114, where the angle α' is 225°. Fig. 26 shows a sectional view along the line AA of the Fig. 24 .

[0164] In contrast to the joint 222 according to the Fig. 14 bis 17 The second part 114 of the joint connection 236 does not have a clamping spring 224, but rather a plug-in means 238, which is connected to the joint connection 236 by means of a plug-in means screw 240. The plug-in means 238 is screwed onto the plug-in means screw 240 (in particular Fig. 26 ) and can be moved along an axis Z of the plug-in center screw when turning the plug-in center screw 240.

[0165] The plug-in means 236 has a bead 242 with an undercut 244 which is configured and aligned to form a snap-in connection with a plug-in means receptacle not shown in detail here.

[0166] The plug-in means 240 is made, in particular, of plastic. The plug-in means 240 is preferably designed to be flexible, so that the bead 242 can be easily compressed when connecting the second part 114 to a strut 102, 104, a rod 106, or a frame rod 180, 182. This allows the bead 242 to be inserted into the receptacles, where the bead 242 expands again and receives the receptacle in the undercut 244.

[0167] As is particularly evident from the Fig. 23 and 26As can be seen, the plug-in screw 240 has a screw head 246 that is received in a countersink 248 of the second part 114. Furthermore, the plug-in screw 240 has a screw shaft 250 that is received in a bore 252 of the second part 114. Furthermore, the plug-in means 238 has a stop 254 that abuts against a counter-stop surface 256 of the bore 252.

[0168] When the plug-in center screw 240 is pulled, the bead 242 can be pulled in the direction of the surface 210 in order to better fix or fasten a receptacle (not shown here) of the rod 106, the first strut 102 and / or the second strut 104 in the undercut 244.

[0169] In contrast to the Fig. 20 bis 23 show the Fig. 24 bis 27 the articulated connection 236 from a different perspective, in which the angle α between the first part 112 and the second part 114 is 224°.

[0170] The hinge connection 236, like the hinge connection 194 or the hinge connection 222, can be used to connect the rod 106 to the first strut 102 and / or to the second strut 104.

[0171] Fig. 28 shows in detail how a joint connection 236 according to the Fig. 20 bis 27 can be connected to the frame bar 180 on the one hand and the strut 102 on the other hand.

[0172] As from the Fig. 28 The first part 112 of the articulated connection 236 is visible in a cavity 258 of the strut 102. The spring clamp leaves 234 of the spring clamp 224 press against an inner wall 260 of the cavity 258 to establish a clamping connection between the first part 112 of the articulated connection 236 and the strut 102.

[0173] At the same time, the plug-in element 238 of the second part 114 of the articulated connection 236 is received in a receptacle 262 of the frame bar 180. An edge 264 of the receptacle 262 is received in the undercut 244.

[0174] Fig. 29 shows a perspective view of a joint connection 266 according to another embodiment of the present invention.

[0175] The joint 266 according to the Fig. 29 In addition to the first part 112 and the second part 114, it has a third part 268 which is perpendicular to the plane in which the first part 1112 and the second part 114 lie.

[0176] The third part 268 has a bore 270 for receiving a fixing means, not shown in detail here, for fixing the third part 268 to a strut 102, 104, to a rod 106 or to a frame rod 180, 182.

[0177] The first part 112 and the second part 114 each have a spring clip 224, the operation of which has already been described.

[0178] The first part 112, the second part 114 and the third part 268 are connected to each other by a screw 272.

[0179] The Fig. 30 bis 33 show in detail the third part 268.

[0180] Fig. 30 shows a bottom view of the third part 268,

[0181] Fig. 31 shows a front view of the third part 268,

[0182] Fig. 32 shows an upper view of the third part 268 and

[0183] Fig. 33 shows a side view of the third part 268.

[0184] As can be seen from the Fig. 30 bis 33As can be seen, the third part 268 has a threaded hole 274 into which the screw 272 can be screwed and, thereby, the first part 112, the second part 114 and the third part 268 can be connected to one another. The screw 272 can be rotatably mounted in the bores 126, 128 of the first part 112 and the second part 114 to enable rotation of the third part about the Y axis. A plug head 273 can be plugged onto the screw 272 and received in the plug head receptacle 275 of the first part 114 to prevent the third part 268 from becoming detached from the first part 112 and / or the second part.

[0185] The bore 270 also has an enlarged area 276 for receiving a nut (not shown in detail here) for fastening, for example, a spring clamp or a plug-in means in order to be able to fix a strut 102, 104, a rod 106 or a frame rod 180, 182 to the third part 268.

[0186] Of course, the invention is not limited to the illustrated embodiments. The above description is therefore not to be considered limiting, but rather illustrative. The following claims are to be understood as meaning that a stated feature is present in at least one embodiment of the invention. This does not exclude the presence of further features. Where the claims and the above description define "first" and "second" embodiments, this designation serves to distinguish between two similar embodiments without establishing a priority.
