Description

The invention relates to a kit for trade fair and shop construction and the same with elongated profiles with holes and connecting elements for connecting the profiles.

Such kits are particularly useful for trade fair and shop construction widespread. The profiles can be in the desired shape be put together. You can then use it to connect cables be pulled through, the construction still just consists of the profiles through which one can easily can pass through, the cables can pass through, etc., so that in this part of the work all parts are very easily accessible are. Only when this construction is finished is z. B. with Velcro connections transparent and opaque Plastic plates or the like on the profiles attached to get the desired room layout.

Although this procedure offers many possibilities and the corresponding constructions for other use can also be dismantled, is to connect the individual profiles very complicated. They have to be together screwed, which is very tedious and often also requires special screwdrivers. Another possibility in such known kits there is Use of special locks, so-called patent locks, which are also complex and cumbersome to use are. What is particularly disturbing is the time involved, since assembly and disassembly often on weekends accordingly higher labor costs must be carried out.

Although with such profiles for trade fair and shop construction, the normally made of metal or plastic, as mentioned the simple quick assembly and dismantling required no solutions have yet been found, such as the profiles easily connected and then again can be separated from each other.

The object of the invention is to provide an improved To create a kit in which the profiles lightly together attached and detached from each other.

The solution according to the invention is that each connecting element can be locked in holes using a wedge is. So it is no longer necessary to screw it all you have to do is insert or drive in a wedge, which then holds the profiles together well. To the profiles again the wedge only needs to be knocked out of each other to become.

In an advantageous embodiment it is provided that it has connecting elements which are rod-shaped or tubular Part with one arranged perpendicular to the same Disc, one at a distance from the disc and his Ends arranged, aligned with a longitudinal plane of the part Have through slot and a wedge, the thickness is substantially equal to the slot width.

The rod-shaped or tubular part is formed by the together aligned holes of two arranged side by side Insert the profiles until the washer is inserted again prevented because it lies against the first profile. The Disk could e.g. B. be round, you will advantageously but make sure that the disc is rectangular

On the opposite side of the pane the stick or tubular part out of the second profile, the elongated slot is exposed. The slot is then in this slot Wedge inserted and pounded so that the two Profiles are clamped together because on one One side of the washer and one on the other side of the wedge Exerts pressure. The corresponding tensile force is from the rod or tubular part added. By simply plugging it in of the rod or tubular part and hammering of the wedge can therefore reliably and the two profiles be quickly connected. This connection can can be released just as quickly by removing the wedge from the Slot is knocked out.

In contrast to the state of the art, one obtains an essential one simpler type of connection, which is also essential is faster to manufacture and solve without this type the connection has a lower reliability than previously known Types of connection. Of course that could Disc can also be replaced by other end stops, as long as they serve the same purpose.

The rod-shaped or tubular part is expediently hollow, So a tube or a sleeve, because it is so lighter and Material is saved.

It is advantageously provided that between profile and Wedge a washer with a guide slot for the Wedge can be used. This guide slot can also be a have an inclined contact surface for the wedge. The disc and the washer, the profile should be as large as possible cover, also extend over the entire width of the same, so that the profile is not deformed by the wedge forces becomes.

In a further advantageous embodiment there are two rod-shaped or tubular elements on their with a disc provided end articulated to a connecting element with each other connected. In this case, the part of the stab or tubular element between a disc and the Slot for the wedge only inserted through one profile at a time and attached to it with the wedge. Possibly. can washers are also provided between the washer and the profile so that the collar and thus the joint of the profile has a larger distance. The corresponding is with the opposite part between the washer and the slot made. As a result of the articulated connection of the two parts the two profiles can then be arranged at an angle to one another be so that even in the case of rectangular Profiles that are attached to each other, angles between can produce the wall parts limited by the two profiles will. Of course, such angled ones Connections are also made between profiles that do not have a rectangular cross-section, e.g. B. round cross section. The rectangular cross-section is used in many cases to be favoured.

It can then also be provided that the kit at a advantageous embodiment has connecting elements, the two articulated slotted tubes, a pull rod arranged therein and a rubber elastic Have sleeve between tie rod and tube, wherein the sleeve is compressible with the help of an external wedge is. Through these elements corner connections in be produced in a particularly advantageous manner. The tubes can namely in different depths depending on the desired angle the holes are inserted without the insertion depth is set by a disc. By collecting the Keils and the resulting force on the tie rod the rubber-elastic sleeve is compressed and expanded the slotted tubes, which are then firmly attached to the bore wall issue. These tubes allow a particularly flexible Construction. When a tie rod attacks the joint, by driving in the wedge also the angle between the connected ones Profiles fixed.

It is advantageously provided that on the tube a piece of pipe can be placed, the inside diameter of the outside diameter corresponds to the tube. This can prevent that the tube expands especially where it is not in the hole, in which case the connection not be tight enough with the hole or profile could.

Yet another advantageous type of fastener is characterized by the fact that it has an angled, in particular rod-shaped or tubular part angled by 90 ° have on the one hand near the bend with Is provided, but on the other side one Has slot for driving a wedge, so that between each disc and each wedge fixed a profile piece can be made, which also creates angle connections can be.

Should not be a vertical one at the end of one profile Profile be attached, but somewhere between the ends of the profile (e.g. for a vertical wall leading to another vertical wall is perpendicular) are expedient Fasteners provided that consist of two right angles interconnectable elongate plates which with at least two parallel rod-shaped or tubular ones Elements are connected, one of which has a slot for has a wedge. The rod-shaped or tubular elements are in adjacent holes in the profile used and wedged. Through the right-angled connection The profiles of the two plates will also be rectangular connected with each other. These fasteners can e.g. B. used on top of walls that are perpendicular to each other should stand. If the elongated plates are still with different Ends can be connected together, so can thereby different distances of the profiles for different Wall thicknesses can be obtained from panels that the profiles are attached.

With rectangular profiles can be advantageous Embodiment very well achieve a grid-like division, if it is provided that the profiles are in the same Distances arranged holes are provided, the distance the center of the hole from the edge of the profile and the Distance of the last hole from the end of the profile equal to half the distance of the centers from neighboring ones Holes of the profile is.

In the places where two profiles meet (be it on the edge or be it at the end of the profile bars) outside hole only half the distance to the edge or end of the profile like the distance between two holes in the profile itself. Since the same half distance also with the each other profile is provided at the edge or at the end, have two adjacent ones at the joint of two profiles, but holes belonging to the different profiles also the same distance as the holes in the profile itself, so that with another profile also such joints can be attacked, but the distances adjacent holes are always identical.

The profiles expediently have at least one lateral one Flange for holding the plastic plates attached to it on. The plastic sheets can not in this way shift their plane while moving vertically on a move especially conveniently held by Velcro will. The profiles are between the two flanges expediently designed to spring back to seamless To enable angular connections.

The kit advantageously has locking balls in one Bore feet to be locked, the height of which by a Screw spindle is adjustable. The locking balls do not have to absorb large forces, only the feet falling out prevent down. Once the kit is set up there is then no longer any risk of the feet falling out. The height of the foot is adjustable by the screw spindle, the one opposite the main part of the foot or the Profile has height-adjustable footplate. To bigger ones Height differences without having to overcome long screwing, can be provided that the screw spindle is not completely is surrounded by a thread, but that the thread through a larger diameter bore running at an angle to it is cut. Then for quick height adjustment the screw spindle is folded into this larger hole, roughly shifted to the correct height and then into the thread be folded back so that the height is then finely regulated can be.

According to the invention further connecting elements such. B. to Attaching shelves and the like may be provided a plate and two round ones supported by eccentric columns Have disks whose diameter is essentially the same Corresponds to the diameter of the holes in the profile. This Slices are inserted through the holes. Subsequently the plate is moved so that it with its eccentric Columns abuts the edge of the hole. The plates can then no longer fall out.

As can be seen from Fig. 1, has an advantageous Embodiment of the profile frame kit with profiles 1 on, which have a rectangular cross section and pairs of Have through holes 2 arranged perpendicular to one another. The geometry is in the cross-sectional view 2 can be seen more clearly, in which also on a Side flanges 3 are shown, on which dashed lines hinted at the cover plates when attached after the profiles in the appropriate arrangement are set up and attached to each other.

Fig. 3 shows an embodiment of the profile 1, the between the two flanges 3 jumps back. So there is here Space for an articulated connection that allows two Profiles connected at an angle to one another without joints can be because of the space between the two flanges 3 can take up the joint.

The connection of the profiles is done as shown in FIG. 4 to 8 can be seen in that two profiles 1 side by side to be ordered. Through aligned holes 2, a tubular part 4 is inserted until a disc 5 arranged at one end against the first Profile is present. A slot 6 protrudes on the other side beyond the second profile 1, into which a wedge 7 is inserted and fastened by hammering in. In this way the two profiles 1 are reliably held.

In the embodiment of FIGS. 4 and 5, the disc is round and the wedge 7 lies directly on the profile 1. In the embodiment 6 and 7, the disc 5 is rectangular and the wedge 7 lies against a likewise rectangular washer 10, making the forces more even on the profile be distributed so that the same is not damaged. In the embodiment of FIGS. 4 and 5, the profiles are of Fig. 2, in the embodiment of Figs. 6 and 7 Profiles of Fig. 3 shown. Even in the representation of Fig. 8, which shows the connection in cross section, are the profiles 3 shown.

In the embodiment of Fig. 9, the rod or tube is more Part 4 curved by 90 ° and has on both sides of the Curvature of a disc 5. One can then on both ends Profile 1 can be attached and each with the help of a wedge pressed against the disc 5 and so attached, the in the slot 6 is inserted.

10 is the embodiment of the connecting element 6 and 7 shown, in which the wedge 7 is no longer directly abuts against the profile, but against a slotted Washer 10 presses so that the profile 1 between the washer 10 and disc 5 is clamped.

The connecting element of FIGS. 11 to 13 has two tubular ones Parts 4, which are slotted and through a hinge 8 are hinged together. In the tubular Elements 4 are each arranged an elastic rubber sleeve 11, the on the inside against a disc 12 and abuts on the outer side against a disc 13, which on a central tie rod 14 is slidably disposed. Becomes the wedge 7, which in this case is U-shaped in the axial direction and can rest against a cross pin 15, driven if the disc 13 is pressed inwards, it expands the rubber sleeve 11 so that the slotted tube 4 also expands and thereby expands in the hole to which it is pushed on, the profile is clamped. The right tie rod 14 acts on the joint 8, whereby it locks and a rotation of the joint is prevented. In order to undesirable expansion is avoided in the area where the tube 4 is not surrounded by the bore 2 of the profile 1 is still a pipe section 15 is placed, the inside diameter corresponds to the outside diameter of the tube, so here no expansion can take place. The connecting element 11 continues to the left of the joint 8 as well this is shown on the right. Instead of the U-shaped wedge 7 and the Cross pin 15 can also be the wedge 7 and the slot 6 of the embodiments 3-9 can be used.

15 and 16, a connecting element is shown, the e.g. B. can be placed on top of profile 1, the right angle should be connected to each other. The fasteners have elongated rectangular plates 27 which can be connected at right angles and two have tubular projections 4, 28 with which they in the holes 2 of the profiles 1 can be used. A each of the tubes 4 is for connection to a wedge 7 intended. At different distances from the Tubes 4, 28 square at the ends of an elongated plate 27 Holes 29 are provided, the two profiles are connected to each other at different distances, to allow different wall thicknesses for the panels, with which the profiles are clad.

The foot shown in FIGS. 16 and 17 has a central threaded bore 16 through which an obliquely extending bore larger diameter 17 passes. A screw spindle 18 with a foot 19 arranged thereon can initially, like this is shown in Fig. 16, be held obliquely so that the height can be adjusted as desired. Then she will then tilted in the axial direction (Fig. 17) when approximately the correct height is set so that the screw spindle 18th comes into engagement with the thread 16. The screw spindle will held in this form by an arranged on it Slidable ring 20 engages in the upper bore 21. The height can then be adjusted by turning a screw head 22 be finely adjusted. At 23 locking balls are arranged, with which the foot is held in a profile bore 2 until the weight of the profile or of the whole kit is held anyway.

18 and 19 a further connecting element is shown, which has an angled plate 24 on which two columns 25 discs 26 are eccentrically attached. This Disks 26 have essentially the diameter of the bores 2 of the profiles and can be inserted into the holes, then, after the plate 24 has moved down, so that it rests with the columns 25 on the edge of the hole, 18 and 19 hooked and secure is held.
