Device for connecting or * connecting

Components

The invention relates to a device for connecting or connecting two components, such as drilling, rods, Profile bodies, flat components, in particular for assembly of room divisions of all kinds, scaffolding, furniture bodies, whereby in the open cavity end of one component e.in Lock can be used, the ends of which by the spreading effect of an expanding or pulling element, rear external walls reach behind the other component.

A large number of such devices are already known, the disadvantage of which are, among other things, that the lock with the lock in the one component on the The component to be connected does not exert any significant locking forces, so that it is not fixed, angularly correct and wobble-free Connection between the components to be connected is achieved. There is another major disadvantage in the fact that the components to be connected look

lent length must be present and thickness within narrow tolerances of its, in order to obtain an exact match and enough solid Ansohluß of the components as ^ z _e B "is required at frame bodies for clamping of wall panels or glass panes ο

Gate directions, the locking of which can exert a tensile force required for a good connection on the component to be connected, are known. However, they have the disadvantage that the tensile forces have to be transmitted via screws or eccentrics as tightening elements to the walls of recesses in the component receiving the lock. Such devices must therefore have at a particular material certain minimum wall thickness to a sufficient support of the plague, dragging elements in the intended especially for them recesses certain size and location in the devices to ensure '■ consists könnenoEine essential difficulty is that also here to connecting components must be cut to specific lengths within tight tolerances and that, in addition, the exact assembly of two components can only be achieved when the recesses for receiving a tightening element are provided in one component at a precisely defined point. This makes it much more difficult to assemble components that are not particularly prefabricated, e.g. for components that are only measured and cut to size at the installation site. The location of the recesses for the Festatelielemente can indeed be found by using stencils, but the careful and time-consuming work of trained professionals requires _β addition, after repeated assembly and disassembly to be joined together or connected component, the recesses for the tightening elements expand and then no more perfect assembly can be obtained »

48, 49, the ends of which come to rest on the inclined surfaces 44 and 45. The locking parts 46, 47 are bent outwards at their rear ends 50, 51 in order to guide spiral springs 52, 53 which act against one another and thus press the tie rods against one another in the central position, while the clamping parts 39 »40 with roughened or toothed outer surfaces the inner walls 54 of the hollow rod 34 are pressed on, one locking part has a threaded hole in a thickening into which a screw 55 is screwed. To access the screw, | an opening 56 is provided in the hollow rod 34 and an opening 57 is provided in the clamping part 40. The connection of the two hollow rods 34, 35 takes place in the same way as the connection of the components 1 and 11 according to Ligur 1o. Here, too, the tensile and compressive forces are brought about by inclined surfaces 44, 45 in contact with special sections 48, 49 of the locking parts. The profile parts of the lock 36 are supported by the specially provided end sections 42, 43 on the outer wall of the hollow rod 35

Figure 3 shows the connection of three hollow sections, of which only the hollow profiles 60, 61 are visible to a cube-shaped connecting body 62. In the two hollow profiles are * corresponding to each other locks. There are two identical U-profiles facing each other as clamping parts 63ί 64, which have flange-like extensions 65 on the rear side, which are provided with openings through which a holding member 66 engages * The front ends 67 »68 protruding from the hollow profile 61 The end faces of the clamping parts 63, 64 serve as contact surfaces on the outer walls of the VeiJb ^ nibüiigle * - / ο? · ^ρβΓΟ The rear ends 69, 70 are provided with openings 71, 72 at their bends. The locking parts 73, 74, the rear ends of which form inclined surfaces 75, 76, partially grip

through the openings 71, 72 of the clamping parts 63 »64, with outer edges 77, 78 rest on the inclined surfaces 75, 76 along the edges of the openings 71, 72. The front ends 79, 80 the locking parts 65 and 64 engage behind perforated outer walls of the connecting body 62. The perforations consist here in an advantageous manner of circular openings 81, which can easily be made with a cutting tool « In Figure 3, such an opening is also shown in plan view and leaves the special semicircular shape of the claws recognize front ends 79, 80 of two locking parts for connecting the third, not visible hollow profile, which through the opening are guided and engage behind the circular opening edge "Between a locking part and a U-shaped clamping part is each a compression spring 82, 83 »the locking parts in the unlocked position press against each other. The locking part 73 is with a threaded hole provided, in which a vision hood 84 engages, which through wall openings in the hollow profile 61 and through an opening in the one clamping part 86 with ample play from the outside is. Correspondingly as in the embodiments according to When the two locking parts are spread apart, FIGS. 1 and 2 initially engage behind the front ends 79, 80 Bands of an opening 81. By further spreading, the U-shaped clamping parts 63, 64 pushed forward until they are 67 »68 come to rest on the outer wall of the profile part 62. By further spreading the tension members are now over to the Edges 77 »78 beveled surfaces 75, 76 pressed further outwards strong locking forces triggered with which the front Ends 79, 80 the hollow profile 62 against the lock parts 63, 64 to press. It is noteworthy that in the execution form after FIG. 3 the height profiles to be connected to one another do not touch each other, and make a solid connection

obtain. As FIG. 3 clearly shows, the hollow profiles 60 and 61 provided with the locks can have different distances from the connecting body 62 to be connected. Since the openings 85 do not serve to support the screws, they can also be designed as a longitudinal slot. The particular advantage is that when connecting hollow profiles provided with differences in length, these differences in length can easily and very precisely be compensated for by the more or less wide protrusion of the clamping parts from the hollow profiles. However, it must be ensured that the openings 85 »86 are chosen to be sufficiently large in order to be able to carry out an axial displacement of a lock in a hollow profile to the desired extent. The vision hood 84 therefore does not protrude laterally from the hollow profile. In the expanded state of the lock, it can even remain behind one clamping part 63.

FIG. 4 shows the connection of two hollow components 87 »88 for extremely high loads, connection strengths of the order of magnitude of riveted connections being able to be achieved. In this case, clamping parts 89, 90 inserted immovably into the hollow profile 87 are inserted, each of which is provided with outer ribs or lugs 91 »92, which engage in bores or slots 93r 94 in the wall of the hollow profile. The front end faces 95 of the clamping parts end with the opening edge of the hollow component 87. The locking consists of locking parts 96 »97 * the ends of which are also bent outwards here. The front ends each form inclined surfaces 98 'and the rear ends form inclined surfaces 102, 103 · Rear inner edges 104 of the clamping parts come to lie on the inclined surfaces 102, 103. On the Sohräg surfaces 98, 99 inner edges 10 _{6 9} 107 come to lie along strips in an opening 108 of the hollow component 88. The one locking part 97 is

Provided with a 6-thread hole for a screw 109 ^ which is accessible through openings 110 and 111 in the one clamping part 89 and in the wall of the hollow component 87, By spreading the locking parts 96 and 97, strong locking forces are created over the inclined surfaces said mating hollow member "applied in the direction of the lock parts It is understood .that the cams 89 and 90 with the hollow member from one piece can be made _a There are then only Hohlbauinnenkanten corresponding to the edges 104 and 105 and front abutment surfaces for abutment with the outer surfaces 94- and W 95 of the hollow component 88 to be connected can also be omitted _f if the J-profiles to be connected have sufficient contact surfaces _o Corresponding edges can also be formed by a groove in the hollow component. Furthermore, it is understandable that the component to be connected does not have to be a hollow component, provided there are undercut walls behind which the bent front ends of the tension members 96 and 97 can grip »

In FIG. 5, a hollow profile 114 is attached to a corresponding hollow profile ″ 115 connected. For this purpose, there is a lock in the hollow profile 114, which consists of clamping parts 116, 117 and locking parts 118, 119 exists. A screw .120 is used as an expansion body through openings 121, 122 in the wall of the hollow profile and in one clamping part in a threaded hole in one Yerriegelungteil 118 screwed and presses against the front side the other locking part 119 · Between a locking part and a clamping part is each a compression spring 123, 124i which the locking parts 118, 119 in the unspread State together. A projection 125 engages the locking part 118 in a recess 126 in the locking part 119. This is between the two locking parts 118, 119 given a connection in the unspread state, the

share more and more elongated leaf springs 213 »214 as well due to the distance which becomes smaller and smaller with the spread of locking parts and clamping parts prevents ©

It goes without saying that the clamping parts and the leaf springs in can be designed in many ways in order to achieve the same effect. So it makes sense to have one locking part each and to firmly connect a clamping part to each other at their rear ends or to form them from one piece "

The execution according to Pig. 7 differs from the j | guidance according to I ¹ Ig. 6 through the design of the clamping parts, which here consist of a coherent clamping body unit 222, curved in the shape of a vase in cross section, the legs 220, 221 of which rest in middle sections on the locking parts 223 »224 and with front and further rear ends on the inner walls of the hollow profile, The rear ends of the locking parts engage behind spread-out end parts 225 »226 of the clamping body unit 222, which open an opening 227 for the ends of the locking parts to pass through. The front sections of the clamping body unit are also perforated or divided for the screw 228 to pass through. , ",

Similar to the exemplary embodiment according to FIG. 3. 6 will be the legs of the clamping body unit are pressed in length by spreading the locking parts. The forces applied for this correspond to the locking forces with which the two hollow profiles are connected to one another.

The locking parts have strong end sections 237, 238 with external teeth, which are in the locked position pressed firmly against the inner walls of the hollow component 230 will. The threaded hole for the screw 239 is provided in the end section of the one locking part. The clamping parts 235, 236 consist of inwardly bent parts, each with rear ends at the front shoulders of the end sections Support 237, 238 «The ends of the clamping parts engage in openings 240, 241» while the front ends of the clamping parts rest on the inner wall of the hollow component. The openings 240, 241 are located in the narrower, front ones Sections, 242, 243 of the locking parts that adhere to the reinforced End sections 237, 238 connect and at their front ends according to the above explanations for Reaching behind the outer walls of the component to be connected are turned. One of the rear end sections 237-, 238 is provided with a projection 244, which is in the rest position of the lock in a recess 245 in the other end section As a result, both locking parts can be coupled in order to be able to move them together into a position suitable for locking. When the locking parts spread the clamping parts are firmly between the outer surfaces of the to be connected Component and the locking parts clamped, whereby a deformation of the clamping parts takes place. This can be "elastic" or "permanent" deformation Act. That depends on whether the closure should be usable one or more times.

In the exemplary embodiments it is clearly shown that the Sohruben act as expansion elements only between the tension members of the lock and are not supported on any wall. The through openings for the expansion elements are therefore not bound to an exact size. It can be useful
