Definitions

  • the invention relates to a height-adjustable suspension device, preferably for suspended ceilings or parts thereof, with axially displaceable, lockable, parallel, preferably rod-shaped support elements and a holding element which receives this and has a screw connection and which comprises a base element and a plate-shaped second element, between which Sections of the support elements can be introduced, the base element and the plate-shaped second element between the support element sections being penetrated by the screw connection (for example BE-A-644 576 and DE-U-1 867581).
  • a suspension device with axially displaceable support elements enables a large adjustment range, since the mutual displaceability of the support elements, which are preferably designed as rods, is only limited by their length (DE-PS 1 289286).
  • the screw connection is tightened so firmly by means of a tool that it is no longer possible to move the rods with respect to the holding element, or there is a connection which is so loose that the rods slide out of the holding element. Both make it difficult to assemble suspended ceilings or parts of them and, among other things, make adjustment difficult for one person.
  • a height-adjustable suspension device for suspended ceilings and pipes enables a pre-adjustment of suspension straps to be connected to a closure part designed as a holding element.
  • a screw is first lightly tightened with one hand, which causes the screw to be pressed into the suspension straps. After this pre-adjustment, the screw is tightened with a key, which completely penetrates the suspension straps and ensures a secure connection.
  • Such a configuration of a suspension device is, however, not suitable for enabling a continuous displacement of the support elements designed as metal strips, since after the tip of the screw has penetrated at least one metal strip, the latter can no longer be displaced with respect to the holding element. Readjustment is therefore excluded. However, this often has to be done during assembly, for example to be able to make an aligned horizontal alignment when the false ceiling is completely pre-assembled.
  • the object of the present invention is to design a suspension device of the type mentioned at the outset in such a way that under-covers or parts thereof can be fastened in a simple manner by means of support elements, preferably designed as rods, which interact with a holding element, in particular when tightening by hand Screw connection pushing the holding elements against each other is possible without the suspended suspended ceilings or parts of them causing an unintentional shifting due to their weight and that there is no danger that the supporting elements can still slide out of the holding elements unintentionally if they are moved by hand.
  • support elements preferably designed as rods
  • the possibility is to be created to check whether the screw connections introduced into the holding elements for fastening the supporting elements are loaded with the required pretensioning force, which ensures a secure and immovable fastening of the supporting elements in the holding element, while at the same time indicating whether the suspension device is assembled or not.
  • the parts required for the holding element should be simple in terms of production technology and thus inexpensive.
  • the plate-shaped second element can be pressed against the base element by means of a spring element designed as a tension spring and also penetrated by the screw connection that can be tightened by hand or with a tool, in order to clamp the support element sections, the spring element preventing an unwanted advancement of the support elements. however, this enables readjustment.
  • the spring element does not act as a locking spring, such as a resilient screw locking device, which prevents the self-releasing of non-positive connections. Rather, a force is to be generated by the spring element in such a way that the support element sections are clamped between the base element and the plate-shaped second element.
  • the force caused by the spring which is preferably linear, depends on the pretension of the screw connection, which is preferably initially tightenable by hand.
  • the spring element ensures that when tightened by hand, the support element sections in the holding element are so What is certain is that an unintentional shift does not take place, but readjustment, ie shifting by hand, is still possible.
  • the screw connection can then be tightened with a tool in order to achieve the required contact pressure, which ensures that the support element sections accommodated by the holding element can no longer slip.
  • the base element is preferably U-shaped, between the legs of which the second element is arranged so as to be displaceable perpendicular to the inner back of the base element, the support element sections preferably running in parallel to the legs or passing through the legs.
  • the configuration of the base element according to the invention results in the advantage, among other things, that the support element sections can be easily inserted and aligned in the base element in order to subsequently mount the plate-shaped second element and the tension spring so that the screw element then passes through between the support element sections .
  • the base element extends along the support element sections and the second element extends in the direction of the recesses and serves to deform the support element sections ( first) has projections, the second element preferably projecting beyond the base element on both sides in the longitudinal direction of the support elements and being provided with (second) projections which interact with the support elements in these regions.
  • the presence of the recesses running in the base element not only results in an advantage in terms of material, but the support elements can be plastically deformed in the direction of the recesses when the screw connection is tightened with a tool, so that this results in an additional securing against displacement.
  • the plate-shaped second element in the area outside the base element has projections which extend in the direction of the base element and consequently cause a reset when interacting with the support elements.
  • the holding element should have at least one display element which extends over the side edges of the base element and which can be sheared off depending on the pressurization caused by the screw connection, preferably in that each leg has at least one mutually associated recess intended for receiving the display element, which each show a (shear) edge running parallel or almost parallel to the longitudinal axis of the support elements, to which the second element can be sheared vertically by shearing the display element.
  • the display element is consequently a control element which indicates whether the suspension device is finally assembled or not, that is to say whether the required pretension and thus pressurization is present between the base element and the second element.
  • the plate-shaped element is moved in the direction of the base element along its inner legs in such a way that it slides along the edges of the recesses provided with the display element, so that the free ends projecting beyond the base element are sheared off and thus fall off.
  • the width of the second element almost corresponds to the clear distance between the inner leg surfaces of the base element.
  • the plate-shaped element has depressions or projections or cutting edges in the area facing the support element sections in order to prevent shearing when the display element is arranged between the plate-shaped element and the support element sections Ensure that the required preload of the screw connection is reached.
  • cutting edges are provided, according to a further embodiment of the invention, these should run parallel to the longitudinal direction of the support elements and, in addition to them, have an angle of inclination. This ensures that there is no change in the contact pressure at the moment the element is sheared off, since the inclination of the cutting edges ensures that the plate-shaped element is already in a non-positive and positive connection with the support elements without an intermediate display element.
  • the support elements should penetrate the legs of the base element, so that the display element is parallel lel runs to his thighs.
  • the support elements should be axially displaceable. This results in torques when suspending large loads between the support elements and the holding element receiving them, which leads to a rotation of the holding element out of the vertical. Depending on the magnitude of the torques that occur, such twisting, tilting occurs to a greater or lesser extent, which in turn manifests itself in a shortening of the suspension device and in a reduction in the cross section of the support element sections in this area.
  • the end regions of the base element and the second element which face away from the attachment point of the suspension device preferably form a shaft which is hollow-cylindrical in the case of composite elements or a recess of a screw which represents a support element section which is screwed and to which a recess for preferably non-rotatably receiving a fixed or detachable head of the further support element is connected in the base element and the second element in alignment with each other or almost in alignment.
  • a central suspension device is made available, the support element sections of which are to be clamped between the base element and the second element form parts of a single, preferably U-shaped support element which can be connected at its apex to a load-bearing ceiling.
  • the centrally arranged recess in the area of the holding element parts facing away from the supporting ceiling is then the starting point or fastening point for the further supporting element to be connected to a lower ceiling or parts thereof, which in turn is preferably a screw.
  • the shaft or the thread of the screw is guided without resistance through the hollow cylindrical recess composed of curved sections in order to pass into the fixed or detachable head, which is received almost non-rotatably by the recesses of the base element and the second element which are aligned with one another.
  • a height adjustability results from the fact that the support element sections clamped between the base element and the second element can be shifted in the same direction.
  • the holding element is composed of a differently designed base element and a plate-shaped second element
  • the base element and the second element are of identical or almost identical design, and that preferably each base element has two recesses in a base area for at least partially receiving the support element sections, preferably has a recess between the recesses for receiving the display element, which extends visibly laterally beyond the elements, and that each recess in the outer edge area is subject to the display element being subjected to sufficient pressure from the screw element shearing edge is limited.
  • the U-shaped base element and the second element are replaced by two preferably cuboid and plate-shaped elements, which have an approximate thickness which corresponds to the diameter of each support element.
  • the support elements are guided in the identically designed elements, they preferably each have two spaced-apart recesses in the mutually facing base surfaces, into which the support element sections can be introduced.
  • the opposite (outer) surfaces then interact with the screw connection, preferably in the form of a screw.
  • the preferably plate-shaped spring element is arranged between the nut and the outer surface of the adjacent base element, in order also to achieve a pretension when tightening by hand, which ensures that the support elements cannot slip out of the holding element unintentionally without ruling out that a hand shift still occurs is possible.
  • the spring element does not act as a securing spring, but is only intended to ensure that the support element sections can be slidably clamped in the holding element during a pre-adjustment.
  • the shearable display element in the form of a flag, for example, is arranged between the inner surface of an element and the support element sections.
  • the outwardly projecting sections are then sheared off by this when the screw connection has experienced the required contact pressure, that is to say when the necessary torque has been applied.
  • the depression runs according to the invention between the recesses into which the flag-like display element is introduced.
  • the outer edges of the recesses receiving the support element sections can be formed as cutting edges in order to enable safe shearing off.
  • the base element receiving the display element with the support element sections should already be and be positively connected. Therefore, the connection between the depressions and the recesses is designed in such a way that the support element sections come into contact with the inside regions of the edges without the display element coming between them.
  • the shape of the recesses and the depressions present between them in the case of composite elements therefore has approximately the shape of a bone.
  • the spring element should be concave to the adjacent plate-shaped element and - as mentioned - have a linear characteristic. Furthermore, the spring element can preferably come into contact with the plate-shaped element in the edge regions thereof.
  • the spring element In order to prevent the spring element from rotating, it can be arranged between the legs of the base element in the case of a U-shaped design.
  • the adjacent plate-shaped element can have projections which extend in the direction of the spring element and which penetrate the latter.
  • the plate-shaped spring element In the case of an identical base element and plate-shaped second element, the plate-shaped spring element can have laterally extending sections which partially surround the adjacent element, thereby ensuring that it cannot be rotated.
  • the screw connection is a screw, the head of which rests on the outer back of the U-shaped base element and has a removable attachment for tightening by hand.
  • the attachment can be a disc-shaped element, which can be plugged onto the head and preferably partially encompasses it, with structuring arranged on the peripheral surface.
  • a type of knurled nut is placed on the screw head, which partially encompasses the edge region of the screw head facing the holding element.
  • this removable knurled nut which is made, for example, of plastic, the screw connection can be tightened easily by hand.
  • the clip-on or spray-on element should have a predetermined breaking point so that it can be removed more easily and knocked off.
  • the element should also have a fluorescent color.
  • a wing screw can also be used, the design of which corresponds in particular to the designs described above with regard to the engagement of the screw head.
  • the screw connection can also be a bolt, the nut of which adjoins the outer back of the base element and can be tightened by hand or with a tool.
  • the nut which is assigned to the head or the nut and is preferably also designed as a square, can be arranged between the legs or can be gripped by the projections which protrude outwards from the second element and counteract the twisting of the spring element.
  • the head of a screw or a nut of a bolt screw is correspondingly arranged on an outer surface, each of which has a knurled nut or wing nut that is designed to be able to be tightened by hand.
  • the lock nut is provided, which is at least partially surrounded by projections protruding from the outer surface or the spring element to prevent twisting.
  • the suspension device consists of two rod-shaped support elements 12 and 14 which axially offset the legs 16 and 18 of a U-shaped base element 20 of a holding element, but extend parallel to one another.
  • the rods 12 and 14 are pressed against the inner back 24 by means of a clamping plate 22.
  • Screw connection 26 is used, which passes between the rod-shaped support elements 12 and 14. The clamping is then carried out by tightening the nut 32 on the outer back when using a bolt screw 46 or a head 28 when using a screw 30.
  • the nut 36 adjacent to the clamping plate 22 is arranged between the legs 16 and 18 in order to prevent the screw connection 26 from twisting when tightened.
  • the legs should have indentations which are intended to accommodate two edges of the nut arranged diametrically to one another. For example, if the nut is a square, the diagonals would run along lines 2 and 3 shown in FIG.
  • a spring element designed as a tension spring 40 is arranged between the nut 36 and the plate 22, the characteristic curve of which preferably runs linearly.
  • This spring element 40 ensures that the nut 32 or head 28 arranged in the back region of the holding element can be tightened by hand, the spring element 40 already having a force for clamping the rod-shaped support elements 12 and 14 in the direction of the back 34 exercises that at least to the extent that a force is applied which prevents undesired displacement or sliding of the support elements 12 and 14 through the openings of the legs 16 and 18.
  • the force caused by the spring element 40 is not so great that a controlled displacement of the support elements 12 and 14 relative to the holding element 20 would no longer be possible.
  • This assignment of the individual elements and their mode of operation makes it easy to readjust the support elements 12 and 14 in order to be able to set the desired spacing of the ends of the support elements from one another, so that the elements arranged on the bottom hook 14 experience the desired orientation.
  • a knurled nut 42 or, for example, a wing 44 or a similarly acting element on the outside back of the holding element can, as the exemplary embodiments according to FIGS. 2 and 3 illustrate 20 existing head 28 or nut 32 may be arranged. Then, after the pre-adjustment, that is to say when the ceiling is to be finally installed, the nut 32 or the head 28 can be tightened with the aid of a tool in such a way that the support elements can no longer be displaced with respect to the holding element, so that a secure Attachment of the ceiling elements to be accommodated by the support elements 12 and 14 is ensured.

  • the clamping plate 52 is provided with projections 54 and 56 arranged in the region of the support elements 12 and 14. If the screw connection is now tightened, that is to say the clamping plate 52 is moved in the direction of the support elements 12 and 14, the display element 50 is sheared off, so that the lateral sections projecting beyond the holding element 20 fall down. According to FIG.
  • the clamping plate 58 has sharp-edged projections 60 in the region of the support elements 12 and 14. If the plate 58 is now moved in the direction of the support elements 12 and 14, the projections 60 penetrate into the support elements, so that a non-positive and positive connection can result. The penetration of the protrusions 60 into the support elements 12 and 14 results in notches which provide additional security against undesired displacement of the support elements.
  • the projections 60 of the plate 58 are arranged with respect to the support elements 12 and 14 in such a way that the notches are made in the fiber direction of the support elements, so that the tensile strength is not impaired.
  • the protrusions 60, their Edges run parallel to the longitudinal direction of the support elements 12 and 14, have an inclination angle to them, so that at the moment the element 50 is sheared away, a positive connection between the plate 58, which, like the support elements 12 and 14, consists of a metal, has already taken place, so that due to the element 50 or its outer sections jumping away, there is no deviating pressurization due to a possible change in distance between the adjoining surfaces of support elements and plate 58.
  • Fig. 4 a further embodiment is shown how the support elements 12, 14 in the U-shaped base element 20 are pressed by means of a screw connection 48 by a clamping plate 62 against the inner back of the base element 20 in order to be able to additionally check whether the Screw connection 48 has already been finally tightened by hand, so that the pre-adjustment has ended or not.
  • a final inspection This is also done again by the leaf-shaped element 50, which is arranged between the support elements 12 and 14 and the adjacent clamping plate 62.
  • the shearing off of the outer sections of the element 50 is brought about by the fact that the supporting elements 12 and 14 in the clamping plate 62 are assigned concave recesses 64, the radius of curvature of which is smaller than the radius of the supporting elements 12 and 14.
  • the edge regions of the concave recesses form 64 cutting edges which cause the shearing off.
  • the cutting edges 64 should be at an angle to the axes of the support elements 12 and 14 for the reasons described above.
  • the nut 66 arranged on the outer back has an attachment 68, which, however, is detachably arranged.
  • This can be a sprayed-on union nut with structuring present on the peripheral surface in the form of, for example, a knurled nut. This makes it easier to put on by hand. At the same time, it should have a luminescent color in order to recognize that manual adjustment is still required.
  • the union nut 68 which is preferably made of plastic, can be knocked off.
  • the snap-on knurled nut 68 preferably has a predetermined breaking point 70.
  • the releasably arranged element 68 is arranged with respect to the screw head 66 in such a way that it encompasses it.
  • the head i.e. the edge area of the head 66 facing the back of the holding element 20, is gripped in such a way that the two conventional screws present in the head area are not exceeded, that is to say when the screw head 66 is tightened by means of the sprayed-on head 68, the positive connection between the head 66 and the outer back of the holding element 20 after removal of the element 68 is not changed.
  • this sprayed-on element 68 is also intended as a marking element, since after being knocked away it indicates to the fitter that the final assembly can take place.
  • the suspension device 10 consequently provides, on the one hand, the possibility of carrying out a pre-adjustment without running the risk that the support elements 12 and 14 unintentionally slide out of the holding element 20 without preventing them from being pushed against one another by hand, and on the other hand the possibility of checks, whether the suspension device is pre-assembled or final assembled or not.

  • the screw 160 In order to pre-assemble installations to be suspended with the suspension device according to the invention, the screw 160 must be tightened so that, as mentioned, a force is generated by the spring 162 to an extent that ensures that the support element sections are clamped between the base element 130 and the plate-shaped element 150 in order to prevent unwanted slipping, but without generating so much pressure that it cannot be moved by hand.
  • the head 168 of the screw 160 is surrounded by a preferably sprayed-on attachment 178 in the form of a wing nut.
  • the wing nut which can also be replaced by a knurled nut, for example, partially engages around the head 168 in the area facing the base element 130, without influencing the positive connection between the screw head and the outside back surface of the U-shaped base element 130, since the known DIN screws have this area, that is to say in the transition between head 168 and shaft or thread, a shoulder, the height of which is not exceeded by the encompassing area 176 of the attachment 178.
  • the attachment 178 or the wing nut can be knocked away using a tool such as a wrench.
  • the attachment 178 can have a predetermined breaking point.
  • the sections of the support elements 136, 138 running in the region of the recesses 146 and 148 undergo plastic deformation in the direction of the recesses. This takes place in that the plate-shaped element 150 has projections 180 and 182 in the areas of its inner surface corresponding to the recesses 146, 148, which, when the screw 160 is tightened, deform the support element sections into the recesses 146, 148.
  • this deformation should be elastic when the screw 160 is tightened by hand, so that when the screw 160 is loosened the original shape is restored.
  • the screws 160 are tightened using a tool, the resulting contact pressure should be so great that there is a plastic deformation.
  • the support element sections running above and below the base element 130 should no longer run parallel, but would describe an angle to one another which is dependent on the extent of the plastic deformation. The larger this is, the smaller the obtuse angle enclosed by the support element sections lying outside the base element.
  • the plate-shaped element 150 is designed to be larger in its longitudinal extent than the base element 130 and, as already mentioned, has in its end regions the bent edges 152 and 154 shown in the exemplary embodiment, which act as restoring elements, that is to say outside the base element Bend 130 extending sections of the support elements 136 and 138 back so that they again run perpendicular or almost perpendicular to each other.
  • a display element in the form of a flag 184 can preferably run perpendicular to the extension of the support elements.
  • the flag 184 is preferably arranged between the surface of the element 150 facing the support elements 136, 138 and the support elements 136, 138. The free ends of the flag 184 then protrude visibly beyond the legs 132, 134 of the base element 130 when the final assembly has not been carried out.
  • the legs 132, 134 have recesses 186 and 188 which are associated with one another and which are traversed by the flag 184.
  • the height of the edge 190 or 192 of the recesses 186, 188 extending from the base 140 to or parallel to this edge roughly corresponds to the diameters of the inserted support elements 136 and 138 and is selected such that the element 150 has the edges 190 and 192 then runs over when the contact pressure required for the final assembly and thus the plastic deformation of the support element sections mentioned has been achieved.
  • the edges 190 and 192 consequently act as shearing edges due to the interaction with the plate-shaped element 150.
  • the support element sections 196 and 198 which are likewise received by a U-shaped base element 200 are part of a single support element, that is to say only in the same direction with respect to FIG the base element 200 slidably.
  • the support element having the sections 196 and 198 is also fastened on the support ceiling side.
  • the structure of the base element 200 according to FIG. 10 corresponds approximately to that of FIG. 9, that is to say it has recesses 204 and 206 embedded in its base area 202, which extend along the support element sections 196 and 198.
  • the task of the recesses 204 and 206 corresponds to that of FIG. 9, so that in this respect reference is made to the statements in this regard.
  • the plate-shaped element 208 which can be introduced into the base element 200 must have projections 210 and 212 which are to be assigned to the recesses 204 and 206, in order to produce the required plastic deformation when the holder is in the finally assembled state.
  • the element 208 On the outer surface of the element 208 there is also a spring element 214 which is concave in the direction of the latter and which causes a force in the direction of the base surface 202 of the base element 200 in order to achieve a clamping of the support elements 196 and 198 to the extent that during preassembly an uncontrolled slipping is not possible, but a targeted shift is possible.
  • the base element 200, the plate 208 and the spring element 214 are likewise penetrated by a screw which corresponds in structure, mounting and mode of operation to that of FIG.
  • the end plate 208 projects beyond the base element 200 in the direction of the attachment point of the support element having the sections 196 and 198, the ends of the opposite ends match, since this end plate should accommodate a further receiving element 216, preferably in the form of a screw and a bolt, which is also used for Example of a false ceiling or parts of it. So that the screw or the bolt 216 can be received from the area facing away from the attachment point on the fastening point side, the edge areas 218 and 220 are widened in an arc to form a hollow cylindrical recess when the receiving device is assembled, that is to say when the base surface 202 and the plate 200 are almost superimposed, through which there is no resistance the receiving element so the thread or the shaft of the screw 216 can be received.
  • Recesses 222 and 224 adjoin the arched edge sections 218 and 220, into which a screw head 226 or a nut of a screw bolt can be inserted.
  • the lateral extent of the recesses 222 and 224 is selected such that it approximately corresponds to the diameter of the screwdriver head 226 or the nut, so that it cannot be rotated.
  • FIG. 10 essentially correspond to those of FIG. 9 in terms of their function and structure, so that no further explanations are required.
  • the legs of the base element 200 have more than one recess 228 and 230, de depth is selected differently. This has the advantage that one and the same base element can be used for support elements of different diameters, without having to do without the fact that a final assembly is indicated by the sheared off of inserted flags 232.
  • the flag 232 must therefore be inserted into the recess 230 if the support element has a large diameter. If, on the other hand, this is small, the recess 228 is to be used. In this case too, of course, the depth of the respective recess must be matched to the thickness of the supporting elements and its plastic deformation when the required contact pressure is reached.
