The present invention relates to a suspension device having a profile rail for arranging vertically on a carrying structure, e.g. a rear wall, a panel, a frame or a framework, and having a bracket which can be suspended in the profile rail. The profile rail has a grid arrangement in which it is possible to suspend the bracket, which is connected to a carrying arm, a crossbar or a shelf carrier. Structures which are formed by way of sections of the profile rail are used, for example, as information and decoration carriers in reception areas or as a framework for displaying goods or exhibits or for storing articles.
A variety of devices for punctiform suspension are known (e.g. EP 0 716 825 B1; WO 99/20094; DE 201 09 028 U1). Suspension devices for the horizontally variable arrangement of carrying arms have likewise been proposed in a variety of configurations (e.g. WO 99/65368; WO 01/43599). Finally, a large number of variants of suspension devices for the vertically variable arrangement of profile rails and brackets which can be suspended therein are known (e.g. DE 201 00 181 U1).
The devices known from the prior art have proven successful in the past. However, there is a need for perfection, i.e. increasing the stability, variability, ease of service and expediency, and for novel solutions which give rise to different possible configurations. In view of this, the object of the invention is to propose an improved and original suspension device which has an increased use value for the field of the invention defined above and comprises a profile rail for arranging vertically on a carrying structure and also a bracket which can be suspended in the profile rail. The intention is for it to be possible for a plurality of brackets to be suspended at different heights on a profile rail, for the brackets to be connected to differently configured load carriers, and for the profile rail to be arranged both in vertical lines, in differing lengths depending on the local conditions, and as short sections.
The suspension device comprises, in the first instance, a profile which is to be arranged vertically and has a front side, two side flanks and a rear side and also engagement contours provided on the profile. The device also contains a bracket which can be suspended on the profile and has fixing elements which are complementary to the engagement contours. The bracket has an encompassing part on which or in which the fixing elements are arranged, and, in the suspended state, encases the front side and the two side flanks of the profile.
The following features relate to specific configurations and variants of the invention: The fixing elements are arranged on a clamp portion of the encompassing part of the bracket, e.g. as fixed elements. As an alternative, at least, and preferably, one removable fixing element is provided. In further alternatives, the fixing elements provided are spring-mounted or inherently elastic. It is possible for the engagement contours in the profile to be located on the rear side or front side of the profile, to be arranged in the side flanks of the profile and to extend to the front side of the profile or to be undercut in relation to the front side.
In one configuration, the profile is T-shaped in cross section with a rearwardly directed profile base, and the transverse leg of the profile forms the front side. This results in two longitudinally running undercuts behind the front side, these undercuts preferably being provided with a grid as engagement contours—e.g. in the form of notches, holes or outwardly oriented punched-out portions. A top clamp portion and a bottom supporting portion are provided on the encompassing part of the bracket, the clamp portion, as fixing element, having hooks which are offset in height in relation to one another. The bracket can only be attached in a twisted state to the profile, as a result of which the clamp portion passes over the front side and, once rotated into the straightened position, engages behind the front side and, finally, moves into the engagement contours.
In further configurations, the profile is trapezoidal or T-shaped in cross section, the wider, front side being at the front, and a mutually symmetrical grid of slots, which is accessible from the front side, being arranged in each case as engagement contours in the side flanks, this producing pairs of slots located at the same height. A top clamp portion and a bottom supporting portion are provided on the encompassing part of the bracket, the portions having fork-like openings which are directed toward the profile and equal the span between a pair of slots, and being spaced apart from one another by a distance which is not congruent with the distance between different pairs of slots of the grid. The fixing elements are formed by claws on the clamp portion. In the suspended state, the top clamp portion encases the profile outside a pair of slots and thus restains the bracket, while the bottom supporting portion, pushed into a pair of slots, supports the bracket vertically.
In the next configuration, the profile is quadrilateral in cross section, a grid of semicircular notches which is undercut in relation to the front side being provided as engagement contours on the side flanks. The two side flanks are symmetrical to one another, this resulting in pairs of notches located at the same height in each case. A bottom supporting portion and a top clamp portion with securing plates suspended in a moveable manner as fixing elements are provided on the encompassing part of the bracket. The securing plates are spring-mounted and/or eccentric and, in the suspended state of the bracket, in the rest position, thus move toward one another and engage in a selected pair of notches. The securing plates are contoured, in order that they remain in the selected pair of notches even when the suspended bracket is subjected to increasing load.
In another configuration, the profile is basically quadrilateral in cross section, a grid of preferably rectangular or polygonal slots which is undercut in relation to the front side being provided as engagement contours on the side flanks; the two side flanks are symmetrical to one another, and this results in pairs of slots located at the same height in each case. The encompassing part of the bracket is designed as a spring-stressed gripper, which has two jaws and can be opened counter to the spring stressing, and the encompassing part has mutually facing noses as fixing elements on its clamp portion. In the suspended state of the bracket, the encompassing part engages around the profile, and the spring stressing forces the noses into a selected pair of slots, as a result of which the bracket is secured on the profile. The gripper jaws are mounted in a rotatable manner on vertical or horizontal pins. The profile can advantageously be joined together from a rear strip, which forms the rear side and contains the grid of slots, and a front strip, which forms the front side and covers over the grid of slots toward the front.
In a specific configuration, the engagement contours are designed as undercut, wedge-shaped slots in the side flanks, have a ledge at the bottom and slope up gradually, preferably in a slanting plane, to the plane of the side flanks. The engagement contours on one side flank are arranged symmetrically in relation to the engagement contours on the other side flank. The fixing elements in the bracket are constituted in each case by a wedge mounted on a spring, in each case one spring and one wedge being provided on either side of an aperture accommodating the profile. The springs and the wedges, inserted in cutouts, secure one another. The profile can be made up of a rear strip, which contains the engagement contours and is preferably made of plastic, and of a front strip. The profile is used as bar material or in short lengths with at least one pair of engagement contours.
In an additional configuration, the profile is rectangular in cross section, a grid of slots with horizontal through-slots being located as engagement contours on the rear side. A bottom supporting portion and a top clamp portion with a transversely insertable securing pin as fixing element are provided on the encompassing part of the bracket. In the suspended state, the securing pin, located in the selected slot, holds the bracket in position.
Finally, a configuration with a hollow profile bar in which the engagement contours are formed as slots in the front side of the profile, and the fixing element is a tongue which fits into the slots, is proposed. The tongue is located on the top edge of the encompassing part, initially extends horizontally in the direction of the profile, and terminates with an upright section.
The invention, then, provides different variants of a novel suspension device having a profile rail which is to be arranged vertically and, depending on the length to which it is cut, a plurality of brackets which can be suspended therein. This gives rise to further-reaching, original possible configurations along with efficient production and assembly costs.
For a more complete understanding of the present invention, reference is made to the following detailed description of exemplary embodiments considered in conjunction with the accompanying drawings, in which:
With reference to the attached drawings, the detailed description of exemplary embodiments of the suspension device according to the invention, in various modifications, will be given hereinbelow.
The following applies to the rest of the description. If, in order to avoid ambiguity in the drawings, a Figure contains designations which are not explained in the directly associated text of the description, then you are referred to the point at which they are mentioned in previous descriptions of the Figures. For reasons of clarity, components are not usually designated again in subsequent Figures, provided that it is clear from the drawings that they are “recurring” components.
In the first variant of the suspension device, use is made of a rectangular, hollow profile rail 1 which has a grid of slots 3 on its front side 10. The associated bracket 2 comprises a cross-sectionally U-shaped encompassing part 20, from which a tongue 21, which is initially angled in the direction of the profile rail 1, projects upward at the top. In the suspended state, the encompassing part 20 engages around the front side 10 and the two side flanks 11,12 of the profile rail 1, the tongue 21 projecting into the selected slot 3 and engaging behind the front side 10 on the inside. For suspending and releasing the bracket 2, the latter has to be angled in order for it to be possible for the tongue 21 to be introduced and removed. In this case, a straight carrying bar is attached, as load carrier 4, to the bracket 2. The encompassing part 20, which is U-shaped in horizontal cross section and is seated, as far as possible, in a play-free manner, on the front side 10 and the two side flanks 11,12, ensures laterally stable positioning of the suspended bracket 2 with the arm-like load carrier 4 extending therefrom.
In a second variant of the suspension device, use is made of a T-shaped profile bar 1, of which the base is directed rearward and the transverse leg forms the front side 10. This results in two longitudinally running undercuts behind the front side 10, these undercuts preferably being provided with a grid 3, which may be formed by notches, holes or outwardly oriented punched-out portions. The associated bracket 2, once again, has an encompassing part 20 with a top clamp portion 22, with hooks 220 which are offset in height in relation to one another, and with a bottom supporting plate 23. In order to attach the bracket 2, the latter is twisted, with the result that its clamp portion 22 passes over the front side 10 and, once rotated into the straightened position, engages behind the front side 10 and, finally, moves into the grid 3 which is preferably provided.
In the third variant of the suspension device, use is made of a trapezoidal profile bar 1, of which the broader front side 10 is located at the front. A grid of slots 3 is provided on the side flanks 11,12. The associated bracket 2, once again, has an encompassing part 20 with a top clamp portion 22, which can be plugged onto the profile bar 1 only on the level of a first pair of slots of the grid 3. The bottom supporting portion 23 of the encompassing part 20 strikes against the profile bar 1 outside a pair of slots of the grid 3 and thus cannot yet be pushed onto the profile bar 1. When the bracket 2 is moved downward, the encompassing part 20 passes, as it were, behind the widening front side 10 and is thus restrained. Once the bottom supporting portion 23 of the encompassing part 20 reaches a second pair of slots of the grid 3, the supporting portion 23 can be pushed in here, as a result of which the bracket 2 hanging on the profile bar 1 is provided with vertical support, while the clamp portion 22, which now encases the profile bar 1 outside a pair of slots, blocks the removal of the bracket 2 from the profile bar 1. The clamp portion 22 and the supporting portion 23 of the encompassing part 20 are spaced apart from one another by a distance which is not congruent with the distance between different pairs of slots for the grid 3.
In the fourth variant of the suspension device, use is made of a cross-sectionally rectangular profile bar 1, on the rear side 13 of which is located a grid of slots 3 with horizontal through-slots and which is likewise intended for fastening on a carrying structure. The bracket 2 has the encompassing part 20 with the securing pin 24 which can be inserted transversely at the top. In the attached state, the encompassing part 20 engages around the front side 10 and the two side flanks 11,12 of the profile 1, and the securing pin 24 can be pushed in at a selected slot 3 of the grid 3. The bracket 2 rests on the front side 10 by way of the bottom supporting portion 23. In order to displace or release the bracket 2, the securing pin 24 has to be drawn out at least to the extent where the previously occupied slot 3 is completely freed.
In the fifth variant, use is made of a T-shaped profile bar 1 which has its wider front side 10 oriented toward the front and has a grid of slots 3 on the two side flanks 11,12. A top clamp portion 22 with hooks 220 and a bottom supporting plate 23 are provided on the encompassing part 20 of the bracket 2, the clamp portion and supporting plate having fork-like openings which are directed toward the profile bar 1 and equal the span between a pair of slots, and are spaced apart from one another by a distance which is not congruent with the distance between different pairs of slots of the grid 3. The hooks 220 can be pushed over the profile bar 1 only on the level of the first pair of slots 3. Once the bracket 2 has been lowered or raised in a defined manner, the fork of the supporting portion 23 can be pushed into a second pair of slots 3, which is located beneath the first pair of slots 3.
In the sixth variant, use is made of a cross-sectionally rectangular profile 1 which has a grid 3 of semicircular notches which is undercut in relation to the front side 10, on both sides, on the side flanks 11,12. The notches on the two side flanks 11,12 are symmetrical to one another and thus each form a pair of notches 3 located at the same height in each case. The bracket 2 has the encompassing part 20 with a clamp portion 22, on which are located securing plates 24 which are suspended in a moveable manner, have an eccentric center of gravity and thus position themselves of their own accord. When the bracket 2 is pushed onto the profile 1, the securing plates 24 rotate outward and, by virtue of the opening, thus allow the bracket 2 to be suspended on the profile 1 to the full extent. When the securing plates 24 pass into a selected pair of notches 3, the securing plates 24, utilizing the clearance, move downward into the undercut notches 3 and thus secure the bracket 2 on the profile 1. A reliable arresting action is achieved by particular shaping of the securing plates 24 and of the notches 3. If it is desired to detach the suspended bracket 2 from the profile 1, the bracket 2 has to be displaced vertically, with the result that the securing plates 24 move out of the previously occupied notches 3, open again as a result and now, for the first time, allow the bracket 2 to be removed from the profile 1.
In the seventh variant, use is made of the same profile 1 as in the sixth variant. The bracket 2 is also very similar. Fixed in an eccentrically hanging state on the clamp portion 22 are approximately semicircular securing plates 24, there additionally being guided in slots and possibly being subjected to stressing by internal spring elements. The two securing plates 24 have inwardly facing noses which are intended for engaging in the undercut unit-spacing notch arrangement 3. When the bracket 2 is suspended on the profile 1, the securing plates 24 are forced outward and thus, in opened state, allow the bracket to be suspended on the profile 1. When the securing plates 24 come to a selected pair of notches 3, the securing plates 24 move downward, and their noses slide into the notches 3. By virtue of contouring on the noses, the bracket 2, even under loading, remains hanging on the profile 1. The disengagement of the bracket 2 is performed, in a manner analogous to the sixth variant, by the bracket 2 being moved upwardly and the opening of the securing plates 24 resulting therefrom.
In the eighth variant, use is made, once again, of a profile 1 with an undercut grid of slots 3 on the two side flanks 11,12. This profile 1 is joined together from a rear strip, which forms the rear side 13 and contains the grid of slots 3, and a front strip, which forms the front side 10 and covers over the grid of slots 3 toward the front. The encompassing part 20 of the bracket 2 is designed as a spring-stressed gripper, which has two jaws and can be opened counter to the spring stressing, and the encompassing part 20 has mutually facing noses 24 as fixing elements 24 on its clamp portion 22. In the suspended state, the encompassing part 20 engages around the profile 1 and the spring stressing forces the noses 24 into a selected pair of slots 3, with the result that the bracket 2 is secured on the profile 1. In order to release the bracket 2 from the profile 1, or to displace it vertically thereon, the encompassing part 20 has to be opened counter to the prestressing of the spring, as a result of which the noses 24 move laterally out of the pair of slots 3. The gripper jaws are mounted in a rotatable manner on vertical pins.
In the ninth variant of the device, use is made of basically the same profile 1, with a grid of slots 3 provided on the two side flanks 11,12, as in the eight variant. Here too, the encompassing part 20 of the bracket 2 is designed as a spring-stressed gripper which has two jaws and can be opened counter to the spring stressing. The fixing elements 24, once again, are mutually facing noses 24 which are provided on the clamp portion 22. In this case, however, the gripper jaws on the encompassing part 20 of the bracket 2 are mounted in a rotatable manner on horizontal pins, with the result that the top clamp portion 22 can be opened counter to the spring stressing. At the bottom region of the encompassing part 20, a corresponding amount of clearance is provided for the encompassing part 20 to move toward the profile 1 when the encompassing part is opened.
In the tenth variant, use is made, once again, of a profile 1 with a grid of slots 3 which is undercut in relation to the front side 10. The grid of slots 3 is provided symmetrically on the two side flanks 11,12, this resulting in pairs of slots, which respective two slots are located at the same height. The slots 3, which are arranged systematically in pairs, have a ledge 30 at the bottom and, at the top, a slope 31 up to the plane of the side flanks 11,12. It is particularly advantageous to design the profile 1 in two parts, namely with a rear strip 18 made of plastic, in which the slots 3 can be made in an advantageous manner, and a front strip 19, which is made, for example, of aluminum and covers over the rear strip 18 to beyond the grid of slots 3, whereby the latter obtains its undercut contour. The two strips 18,19 are joined together in a form-fitting manner. An arrow marking on the rear strip 18, for example, could indicate the correct assembly direction. One configuration of the profile 1 is provided for screw connection at the rear—through the rear strip 18—(see
The bracket 2 has a U-shaped, vertically extending aperture, which is complementary to the cross section of the profile 1, in order to receive the profile 1 with its front side 10 and its two side flanks 11,12, when the bracket 2 is suspended in the profile 1. In the top clamp portion 22 of the bracket 2, wedges 50 are inserted on either side of the aperture, these wedges 50 being mounted on springs 5, being moveable to a limited extent to the side and being provided for elastic engagement in a selected pair of slots 3. As a result of the springs 5, the wedges 50, the tips of which project into the aperture in the rest position, are prestressed toward one another. The wedges 50 and springs 5 are separate components which—inserted in cutouts in the clamp portion 22—secure one another.
If the bracket 2 has been suspended correctly and in a load-bearing manner at a selected height in the profile 1—this state is defined as the latching position—the wedges 50 advanced by the springs 5 project into the pair of slots 3 and are seated on the ledges 30 of the two slots 3. The vertical load component which is acting from the suspended bracket 2 on the carrying profile 1 is absorbed by the wedges 50 engaging in the pair of slots 3. The downwardly oriented oblique load component is absorbed by the supporting portion 23 and the sides of the wedges 50. The wedges 50 have been moved largely toward one another and a downward movement of the bracket 2 is blocked (see
The sliding position (see
As the bracket 2 suspended in the profile 1 moves up further, and thus leaves the originally occupied pair of slots 3 to an increasing extent, the free position of the bracket 2 is finally reached (see
In the separated position, the bracket 2 has been removed from the profile 1; the wedges 50 have been moved all the way into the limit position in the aperture by the springs 5 and are now spaced apart from one another by the smallest distance (see
The profile 1 which is made up of the rear strip 18, with the grid of slots 3, and the front strip 19 is regarded as being particularly advantageous. The bracket 2 which is shown hanging on the profile 1 in
For specific configurations and applications, short lengths of the profile 1 can be fastened on a carrying structure. Such lengths have at least one pair of slots 3 located opposite one another. It is also possible for the brackets 2 to be suspended on such lengths of profile 1, a vertical height displacement being dispensed with here (see
