Abstract

The invention relates to a wedge action connector, especially for construction equipment, with an extended support, a releasably securable holding component longitudinally movable thereon which is stable in position at various longitudinal points on the support, which has an aperture at least partially surrounding a support with a limited range of movement, the cross-section of which is somewhat larger in at least one direction transversely to the support than the latter's corresponding cross-section, and with a securing wedge having two impact ends, the cross-section of which increases in its longitudinal direction, which can also be inserted through a safety aperture merging into the acceptance aperture and which in the secured position, bearing laterally on the support, clamps the holding component securely in position against the support. To improve handling and reduce the space required, the invention proposes that the safety wedge is arc-shaped and both its impact ends point roughly in the same direction.

Description

Cellar connection

The invention relates to a wedge connection, in particular for construction equipment, with an elongated support bracket, with a fastener that is displaceable thereon in the longitudinal direction thereof and can be fixed in position in various longitudinal positions of the support bracket, and which has a receiving opening at least partially encompassing the support bracket with limited movement play, the transverse dimension of which in at least one direction transverse to the longitudinal direction of the support bracket is slightly larger than its corresponding transverse dimension, and with a two-ended securing wedge, the cross-section of which increases in its longitudinal direction, which can also be inserted into the fastening element through a securing opening which merges into the receiving opening and which is in the fastening state under lateral attachment to the support bracket braced the fixing element against the support bracket

In such cell connections, the striking ends of the essentially straight securing wedge point in opposite directions. Therefore, sufficient space must be available for fastening and releasing the wedge connection on both striking ends. The securing wedge generally extends in the longitudinal direction of the holding bracket

REPLACEMENT LEAF If the safety wedge is installed transversely to the longitudinal direction of the support beam, the problem then arises that the safety device is to be attached transversely to the longitudinal direction of the support beam Impact forces hit the support bracket crossways, which can more easily lead to damage. In addition, a sufficient distance to the adjacent support bracket must then be maintained

The present invention is therefore based on the object of providing an improved wedge connection of the type mentioned in the preamble of claim 1, in which more economical use of space is possible and which is easier and more expedient to handle

To solve the problem, a wedge connection of the type mentioned in the preamble of claim 1 is characterized according to the invention by the features listed in the characterizing part of this claim. This achieves the effect that for fixing the connection and for knocking out the securing wedge essentially the same Direction of lay applies This results in a much easier handling, for example when alternating fixing and loosening is necessary when setting up the longitudinal position of a fastener to be fixed on the side member.There is also a significantly smaller space requirement, so that several connections can be made in a smaller space without them interfere with each other regarding handling

According to the embodiments of claims 2 to 4, there are several possibilities of wedge design by changing its width and / or its thickness. This allows the shape of the securing wedge to be optimally adapted to the respective application

REPLACEMENT LEAF A change in the wedge width is particularly useful.

The development of claim 5 leads to a uniform functional behavior when handling the safety wedge. In contrast, the further development of claim 6 enables an initially fast, coarse fixing and, due to the then smaller enlargement of the cross section, very large fixing forces at the end of the fixing wedging of the securing wedge. This promotes the handling and the reliability of the wedge connection.

The design of claim 7 is particularly simple and inexpensive to manufacture. To do this, it is only necessary to bend the suitably shaped wedge structure punched or sawed out of the band material sufficiently far transversely to the band plane so that the striking ends point approximately in the same direction.

In the embodiment of claim 8, particularly favorable power transmission ratios result because of the half-ring shape. This applies in particular in connection with such a safety wedge, in which only its width (transverse to the plane of curvature) changes. The term semi-circular shape is also intended to encompass securing wedges that are curved more or less than 180 degrees (deviating from this by less than 90 degrees).

The end striking members according to the developments of claims 9 to 13 allow very favorable handling when hitting the safety wedge. In addition, the shape and / or the attachment of the striking elements of the respective application, such as the spatial conditions, can be suitably adapted.

Depending on the application, the training of claim 14 or 15 can be chosen. In general, the design of claim 14 should be cheaper for reasons of stability, because the impact forces then run in the longitudinal direction of the holding support, and not transversely thereto. However, if several fastening elements are to be fixed in close succession on the holding support, the design from claim 15 can be cheaper or necessary

The design from claim 16 has the advantage that, because of the fork shape, the fastening element can be placed laterally onto the support beam in a space-saving manner, that is, it does not have to be pushed onto the support beam in the longitudinal direction have the same material cost stability advantages

In the variant from claim 18, the securing wedge is located at the end of the fastening element, so that this does not interfere with the handling of the securing wedge

For certain applications, the design of claim 19 can be useful and sufficient

The invention is explained in more detail below using exemplary embodiments shown in the drawings

7 shows a schematic embodiment of a second embodiment with a screed holder and

Fig. 8 shows the second embodiment in a side view.

The first embodiment from FIGS. 1 to 6 relates to a wall bracket holder in which a horizontal support bracket 10 projects at right angles from a wall and carries a vertical fastening element 12 for attaching any parts, such as components. This can be adjusted along the support bracket 10 and can be fixed at any intermediate station by means of the wedge connection according to the present invention.

The support bracket 10 of FIGS. 1 to 6 is attached to a wall bracket 30 which is vertical in the installed state and which can be screwed onto a wall 34. The free end of the support bracket 10 is supported on the wall bracket 30 by an inclined wall support 32.

The second embodiment from FIGS. 7 and 8 relates to a screed holder 36, in which a vertical support beam 10 can be fixed, for example, laterally on a stair step or on a building board by means of a clamp-like end structure. A movable fastening part 12 of the clamp-like structure is adjustable along the support bracket 10 and can be fixed at any intermediate station by means of the wedge connection according to the present invention.

REPLACEMENT LEAF At the end of the support bracket 10 of FIGS. 7 and 8 there is a stationary foot abutment 38 which, together with the adjustable fastening element 12, constitutes the clamp-like structure for clamping the entire screed bracket The screed bracket can also be fixed laterally on a stair step, the underside of which is inclined corresponding to the stair incline

Both embodiments, as well as many other possible variants, work on the same principle. Parts of the first and second embodiments which correspond to one another therefore have the same reference numerals. The first embodiment is explained in more detail below with the figures, this explanation also correspondingly applying to the second embodiment

The fastening element 12 has a receiving opening 14 which at least partially surrounds the holding carrier 10. Since the fastening element 12 must be applied laterally to the holding carrier 10 in the embodiments shown, the receiving opening 14 is open on one side, that is to say U-shaped or fork-shaped ( 3 and 5)

A securing wedge 16 is used to fix the fastening element 12 to the holding bracket 10 and, in the present case (for example according to FIG. 6), is curved in the shape of a semi-ring by approximately 180 degrees. The securing wedge 16 has plate-shaped welded ends 18, 20 which are welded to it in approximately the same direction. approximately radially oriented striking members on these facilitate the application of the striking forces required for fixing and releasing the securing wedge 16

The securing wedge 16 shown has in its plane of curvature a length over its length

REPLACEMENT LEAF wa constant thickness (Fig. 6), while the transverse width of the locking wedge 16 increases from its striking end 20 to its striking end 18 (Fig. 1 to 5). In principle, instead of or in addition, it is possible to increase the thickness of the securing wedge 16 measured in the plane of curvature between the striking ends 20 and 18, as can be seen in the second embodiment (FIG. 7).

A securing opening 22 for receiving the securing wedge 16 passes through the free end of the fastening element 12 and the receiving opening 14 and in the present case runs transversely to the latter. It ensures that the securing wedge 16, which increases in cross section in the turning direction, increases the distance measured transversely to the longitudinal direction of the holding bracket 10 (running vertically in FIGS. 1 to 5) between the edge of the holding bracket 10 and the boundary of the securing opening 22. As a result, the fastening element 12 is pressed in its longitudinal direction against the holding support 10 and is thus fixed thereon.

The U-shaped, downwardly opening receiving opening 14 is delimited at its upper end by a welded-in fork connecting member 24 and laterally by fork legs 26 of the fastening element 12. The securing opening 22 has on one side a stable welded wedge component 28 which absorbs the impact forces.

When the safety wedge 16 is driven in by striking its thicker striking end 18, it moves increasingly under the direction-changing system on the wedge joint member 28 through the safety opening 22, the fastening element 12 being braced on the support bracket 10. If, on the other hand, the striking end 20 is struck, it moves in reverse and the tension connection is broken.

Since in the two embodiments, the securing opening 22 transversely to the longitudinal direction of the

REPLACEMENT LEAF Holding bracket 10 extends, the striking ends 18, 20 of the securing wedge 16 of the illustrated embodiments in the installed state extend approximately in the longitudinal direction of the holding bracket 10. As a result, the impact forces are very inexpensively absorbed by the holding bracket 10 obliquely to - then runs the striking ends 18, 20 in the installed state transverse - or oblique - to the longitudinal direction of the support bracket 10

If, instead, only the thickness of the securing wedge measured in the plane of curvature were to be changed in a construction variant, this would have to be installed in the first embodiment with downward or upward-pointing striking ends and in the second embodiment with forward or backward-pointing striking ends the thickness of the locking wedge can be changed in the manner of an arrowhead

The wedge connection of the present invention is extremely versatile, for example in the construction industry for construction equipment. The wedge shape can be modified in many ways. It is important, however, that the striking ends should not point in opposite directions as in the prior art, but at least approximately in the same direction a possible deviation in direction of the two striking ends from 180 degrees is less than ± 90 degrees
