The present invention relates to a clamp for connecting a molded panel having webs at its edges, arranged side by side in a plane, which clamps two longitudinally spaced longitudinal surfaces of the edge webs in contact with each other. It includes a clamping jaw, and also includes an actuating element for pivoting these clamping jaws, the two clamping jaws each being positioned at the distal end of the clamping point and spaced apart from the swing bearing. And the actuating element is supported on a mount attached to the clamp, which is also pivotally mounted with the two clamping jaws.

A clamp was disclosed in German Utility Model No. 88 14 208, which proved to be particularly useful for relatively large and hollow edge sections. By the way, this requires two clamping jaws to have an adjustment arm that extends forward and overlap each other as it becomes approximately L-shaped, interlocked with each other by his pivoting or pivoting bearing with two arms eccentric in the area where the two adjustment arms overlap. It must be able to lose weight and to move perpendicular to the molding surface. This is simple because of the eccentric form of the predetermined fastening effect is generated. However, since both clamping jaws must overlap one another on the adjusting arm, corresponding space is required or the possibility of selecting the material cross section is limited, especially in the load zone.

Another type of clamp is disclosed in DE-27 59 966 C2, in which no clamping jaws or arms are pivotally mounted on the support, but can be operated mutually with the help of overlapping adjustment arms. This adjusting arm is traversed jointly by a wedge and the two adjusting arms are driven so that the clamping arms are pulled together and tightened. These wedges should be arranged so that their width is approximately parallel to the forming surface. The working wedge is in the opposite direction to the forming surface and is at an angle of approximately 90 ° to the forming surface, and the direction of movement of the wedge is again parallel to the forming surface. Due to this, as the wedge is operated, not only the adjusting arms can be moved to each other, but also one can be pressed to the other at the same time, and the incident frictional force is made to be the minimum portion of the clamping force.

In addition, a clamping device for interconnecting the edges of adjacent molding panels is disclosed in DE-35 17 307 A1, which has a second clamping jaw with a fixed clamping jaw by pivoting on the support and stopping. The pivoting movement in can be made with the aid of a threaded operating piece that can move approximately perpendicular to the forming surface and can be moved through an L-shaped limb. The opposite clamping jaws thus result in different movements, and additional means are required for the selected movement to the pivot member with the aid of a screw spindle performing a linear movement.

It is therefore an object of the present invention to provide a clamp of that kind mentioned at the outset, where the advantages of the two clamping jaws, which are allowed to pivot relative to one another and to the support, remain intact, nevertheless simple operation without the need for pivot bearings. Element may be used.

The object is that a large plane is arranged in the turning plane, a small plane is supported for the face of the support that faces the forming surface, and another small plane of the wedge is supported for the application point of the clamping jaw, and is spaced apart from the turning bearing. Achievement is achieved by the fact that the wedges arranged in position are actuating elements, and the working points of the two clamping jaws are arranged on opposite sides, respectively, and at both ends of the wedges, the wedges protrude past both clamping jaws at the working points. This is achieved.

Thus, the forming panel is provided with a very simple actuating element, i.e. the wedge, which prevents the traversing of the overlapping part of the wedge so that one of the parts to be moved forward with each other is arranged in the direction in which the wedge moves relative to the other. And the plane of the wedge acts directly on the point of application without the parts to be pivoted contacting and rubbing against each other. The wedges are arranged in a plane substantially perpendicular to the forming surface, i.e., generally in a horizontal plane, while the two wedge surfaces, which are angled to each other, are arranged in a vertical plane, one of which is parallel to the forming surface. The other is angled to it. The wedge can be moved in one direction and by this means the clamping jaw is pivoted about its support and can be operated very simply because the clamping jaw is loosened or released by the movement in the opposite direction of the wedge.

The support is hollow in cross section and has at least one rim which is parallel to the swing plane and which receives the swing bearing of the clamping jaw, and which is located opposite to the molding surface and functions as the junction of the wedge. In the case of one rung, said wedge is particularly useful. In addition, the wedge is particularly useful when the support is angled or U-shaped, so that each side or U-shaped crossbar forms a junction of the wedge. Each of the other sides or U-rims makes contact with the free edge towards the forming surface in use, the actuating wedge is located between the pivoting bearing and the joining point, and the actuating point of the clamping jaw protrudes from this intermediate space. .

The point where the wedge is applied to the clamping jaw is closer than the distance of the slewing bearing to the junction.

The clamping jaws have a partially angled or approximately U-shaped cross section so that they can overlap in the outside with the support in the area of the slewing bearing, and can also be externally engaged by the support of the U-shaped cross section. This results in a robust and stable design where the forces generated can be symmetrically applied.

In the area of application of the wedge, the clamping jaws extend longitudinally and pass through the swivel bearing, and preferably the clamping jaws have an open and extended slot (partly clamping the wedge and the small plane of the wedge). If there is, the force can be applied well by simple guidance of the wedge. That is, the cross section of the wedge is projected to engage the elongated slot to contact the slot and the junction, so that the wedge is engaged not only in its small plane but also in its width portion and guided well.

It is desirable if the elongated slots clamping the wedges have a width slightly greater than the thickness of the wedges and engage both large planes of the wedges to allow planar guidance of the wedges.

The guide slots may be of equal length in both clamping jaws, and the clamping jaws may be arranged at different angles with respect to the cross-sectional plane perpendicular to the support and its crosspiece. Alternatively, the crosspiece of the support may be positioned such that the angle of the two tapered working planes of the wedges is arranged with respect to the grating surface. In this way, the wedge, which is simultaneously engaged with both clamping jaws by the shape of the wedge, is applied to one clamping jaw narrower than the other clamping jaws. On the other hand, it is conceivable to allow the length of the slot to be applied to various widths of the wedge.

The wedge may have at least one protrusion that functions as a stop that protrudes the wedge plane at its tapered narrow end to prevent the wedge from leaving the clamp. By doing so, the wedge is not detached and the narrow end thereof is widened to facilitate the movement of the wedge to the position where the wedge is released by the extension of a hammer or the like.

At the wider end of the wedge there may be a protrusion that projects across the direction in which the wedge extends, which protrudes opposite the forming surface. This also makes the operation of the wedge easy and improved. Moreover, even if the wedge is too close to a hard web or the like to access the narrow end of the wedge, a blow extension or the like can be used for the projection of the released wedge.

The improved advantage of the present invention, which makes the force applied to the wedge more effective in closing the clamp, is that the inclined small plane of the wedge (located at the wide end of the wedge and clamped across the longitudinal direction in which the wedge extends) is clamped. The wedges are arranged across the direction of movement) may be at points which extend obliquely such that an acute angle is formed between this inclined subplane and the subplane of the wedge opposite the swing bearing. The angle of inclination of the inclined subplane and the angle of the other subplane of the wedge is selected such that the vertical line on this inclined plane and its extension line intersect the space between the two clamping jaws, ie the wedge moves as well as possible in the open state. Both during and / or with the clamp closed. As the wedge is inserted, this vertical line also moves upward from the open outside of the intermediate space.

The striking force that makes the wedge work through the incline allows it to be more effectively and better transmitted to the clamp through the wedge. The inclined striking surface at the wide end of the wedge makes the component of the force in the direction in which the clamping jaw extend so that each clamping jaw away from the slewing bearing is closed faster and more about the pivot axis. You will be able to turn with increased strength. This occurs in both clamping jaws.

Thus, it is not used to increase the width of the wedge to make the clamping jaw even better, but a portion of the striking force is transmitted directly to the turning motion of the clamping jaw. The component of the other longitudinal force of the wedge affects the desired and desired operation of the wedge's motion. Experiments have shown that this arrangement allows the wedge to be inserted quite easily and without vibration, thereby correspondingly clamping the jaw effectively without causing unnecessary elastic deflection of the forming panel in the edge web to be clamped.

The inclined small plane preferably continues to the end of the projection provided at the wide end of the wedge. This results in a larger hitting plane with respect to the direction of operation and a good hitting point.

A further improved aspect of the present invention is to facilitate the loosening of the clamp, in that a narrow inclined plane is formed at the narrow end of the wedge at an obtuse angle with the first small plane opposite to the pivot bearing of the clamp. have. This small inclined plane serves as the striking surface of the striking tool during relaxation. In other words, the short end plane of the wedge is disposed to be inclined opposite to the long end plane to improve the distribution of the component of the force when the surface is hit. Thus, the relaxation of the wedge can also be simplified simply because a significant portion of the striking force is directly converted to the clamping jaw's turning motion.

The angle of inclination of the narrow end inclined plane of the wedge is selected such that when the clamp is closed, the vertical line on this inclined plane is directed toward the clamping area of the clamping jaw. It can be seen that this is equivalent to the corresponding angle of inclination at the wide end of the wedge, on the one hand turning the clamping jaw as directly as possible and on the other hand the acting force (clamping the forming panel at the edge web). It proved to be a good match for inserting or removing wedges without causing vibration. A simple blow proved to be enough to fix and break the wedge. Because the clamp arrangement does not have internal elasticity.

Overall, the clamps are easy to operate and store, with all components pending. In use, the wedges are positioned approximately horizontally so that the clamps of the present invention embodied in close proximity can be secured in close proximity to the top or bottom of the molded panel without contacting a surface such as the ground at the bottom edge of the molded panel.

The two embodiments of the present invention having the same main characteristics will be described in more detail below with reference to the accompanying schematic drawings.

The clamp 1 is arranged side by side on a plane and functions to connect the forming panel having the edge web 3 to the edge of the forming panel 2, and the clamp according to FIGS. 2 and 3 in use. (1) is applied to the edge web (3) to press together the edge web (3) in contact with each other.

For this purpose the clamp is provided with two clamping jaws 4 which are adapted to press together the grooves 3b of the edge web 3 and the longitudinal surfaces 3a spaced apart from each other by pivoting forward, and It further has an actuating element (described below) which pivots and tightens the clamping jaw 4.

According to the illustrated embodiment, the two clamping jaws 4 each have an application point 6 of the actuating element, which actuating element is a wedge 7 in the embodiment, the application point 6 being a groove 3b. ) Is located at the opposite end of the clamping point or clamping protrusion 4a which is engaged with and is spaced apart from the pivoting bearing 5. This actuating element, i. E. The wedge 7, is supported on a support 8 attached to the clamp 1, with the support being provided in such a way that the clamping force is applied, moved and retained.

As already mentioned, the actuating element for this purpose is a wedge, which has its large plane 7a arranged in a pivot plane, ie at right angles to the pivot axis 5, and the first small plane 7b being It is supported so as to face the surface of the support 8 facing the molding surface 9 of the molding panel 2, so that the second small plane 7c faces the application point 6 of the clamping jaw 4. Supported, but the counterplanar 7a is arranged spaced apart from the pivoting bearing 5. The application points 6 of the two clamping jaws 4 are arranged next to the swivel bearings 5 facing each other, the wedge moving from the point shown in FIG. 1 to the point shown in FIG. Thereby having enough lever arms to lead the clamping points 4a of the clamping jaw 4 to pivot forward. The wedge 7 has its two ends protruding beyond the clamping jaw 4 at the application point 6 such that both clamping jaws 4 pivot about the support 8 through the movement of the wedge 7. .

In particular according to FIG. 3, the support 8 has a hollow cross-section and is arranged in parallel with the pivot plane and at least one limb functioning to receive the pivot bearing 5 of the cladding jaw 4 ( It has 8a) and is located apart from the shaping surface 9, and has a crossbar 8b which functions as a junction point with the wedge 7 and the wedge surface 7b. The support may be angled, but in the embodiment it is of a particularly suitable U shape, the crossbars 8b of which form the wedges and junctions already mentioned, while the two rims 8a are pins. Or traversed by pivot 5 in the form of a bolt. The line connecting the application point 6 is closer to the joining point, i.e., the crossbar 8b, than the line connecting the swing bearing 5 of the clamping jaw 4, and the application point 6 is in this embodiment. Since the space is larger than the two slewing bearings 5 and larger, the wedge is inserted from the point shown in FIG. 1 to the point shown in FIG. 2 so that the clamping jaws 4 pivot against the support 8. do.

As shown in FIG. 1 and FIG. 2 on the one hand, and FIG. 3 on the other hand, the clamping jaw 4 has a part of a substantially U-shaped cross section, and in the region of the turning bearing 5 The support 8 is overlapped from the outside. Conversely, it will also be possible for the clamping jaw 4 to be grabbed from the outside by the support 8 of the U-shaped cross section.

In the region of the application point 6 of the wedge 7 the clamping jaw 4 extends in the longitudinal direction to pass through the pivoting bearing 5, and according to FIG. 1 one of the clamping jaws is opened in the opened state. It may also protrude past). According to FIG. 3, the clamping jaws 4 each have an open and elongated slot 10, which tightens the wedge 7 and the second small plane 7c of the wedge that fits into the slot 10. .

In the light of FIG. 3, it is clear that the wedge is partially inserted into the slot and guided by the slot. This is an improvement in that the elongated slot 10 which clamps the wedge 7 is slightly over the thickness of the wedge and guides the side of the wedge 7 in two spatial positions so that the wedge is It is well guided and seated. On the other hand this causes the clamping jaw 4 to be fixed against the wedge and to bind well with the support 8.

In the illustrated embodiment the guide slot or the elongated slot 10 is of equal length in both clamping jaws 4 (though the wedges vary in width in each slot), and thus the clamping jaws 4 Is arranged at different angles (at an acute angle with respect to the large plane of the edge web 3) with respect to the cross-sectional plane perpendicular to the support 8 and its crosspiece 8b, or the crossbar 8b of the support 8 in use. Is positioned relative to the forming surface 9 at the same angle as the tapered working surfaces of the wedges 7 are arranged mutually. In the light of FIG. 2, in use, the two clamping jaws 4 are approximately symmetrical with respect to the edge web 3, and the support 8 with the cross bars 8b is slightly inclined so that the wedge is tapered. It is clear to let go.

The wedge 7 has a projection that functions as a stop 11 that protrudes on the wedge surface 7c at the tapered and narrow end and prevents the wedge from escaping from the clamp. Furthermore, this makes the end of the wedge wider, making it easier to hammer the wedge off.

According to the illustrated embodiment, at the wide end of the wedge 7 there is arranged a protrusion 12 which protrudes traversely in the direction in which the wedge extends, in which the protrusion is opposite to the forming surface 9, i.e. stops. It is arranged in the direction opposite to the forming surface 9 of (11). The protrusion 12 causes the wedge to have an enlarged end thereof so that the hammer strikes at this end can increase the clamping force. This arrangement of protrusions 12 also allows the opposite side to be hit when the wedge is unwound.

The wedge 7 and its large plane 7a are arranged horizontally with respect to the edge web which is generally vertical, so that the clamp can be secured without making the operation and movement of the wedge very close to the obstacle perpendicular to the edge web to be joined. For example, it can be fixed in close proximity to the ground or brackets. Although the clamp 1 is placed just above the bottom of the molding panel, the wedge can be driven without difficulty, which is impossible in such a position if the wedge is to be driven vertically.

According to FIGS. 1 and 2, the support 8 between the slewing bearings 5 has a joining point and a designated plane 13 on the side facing the forming surface 9, which can be called a stop plane and It is against the end (free edge) of the edge web 3 which is tightened by the clamp in use. The dimension is selected in such a way that the tension force to the design plane 13 at the point of clamping is generated by the clamping protrusion 4a through the groove 3b, so that any initial small displacement of the edge web 3 is reduced. It can be leveled by interlocking.

In total, the clamp 1 is simple to operate to connect the edge web 3 and is nevertheless efficient and ensures that it consists of several simple parts which are connected in the middle in a mooring manner without having to be assembled. .

The above advantages are also realized in the embodiments according to FIGS. 4 to 6, which are designated by the same reference numerals.

By the way, in contrast to the first embodiment, in the embodiments of FIGS. 4 to 6, the first inclined small plane 14 (located at the wide end of the wedge and intersected with the longitudinal direction of the wedge, and the clamp is tightened) Is arranged to intersect the direction in which the wedge is moved) so that the forming panel 2 is formed in such a manner that an acute angle α is formed between the first inclined small plane and the first small flat surface 7b opposite the swing bearing 5. It is designed to be inclined to a part of the opposite side of the). In order to explain this angle (alpha), the 1st small plane 7b was extended to the intersection with the 1st inclined small plane 14, and is shown in FIG.

The inclination of the angle α and the first inclined subplane 14 is selected such that a vertical line on this inclined plane and its extension line intersect the space between the two clamping jaws 4 and, therefore, in the initial state (open state) The vertical line on the inclined plane is approximately directed to the area of the clamping protrusion 4a, and in the tightened state (FIG. 5), the line is turned even if it also crosses the space between the two clamping jaws 4 It is very close to the bearing 5.

The inclined small plane 14 continues to the end of the protrusion 12 for good operability.

An opposite slope is provided at the end of the first inclined subplane 14 opposite to the projection 12 to reduce the entire length of the wedge to some extent and to allow for good propagation of the blow through the wedge to the clamping jaw 4 in use. It is guaranteed to be the hitting area of the wedge.

At the narrow end of the wedge 7 the second inclined small plane 15 is formed partially to the oblique angle β with the first small plane opposite to the turning bearing 5 of the clamp 1 to relax the clamp 1. It acts as a hitting surface for the blow tool when doing so. The inclination angle β of the narrow end of the wedge 7 is selected such that when the clamp 1 is tightened, the vertical line on this second inclined surface is approximately directed to the clamping region of the clamping jaw 4, thereby providing a clamping jaw 4 at relaxation. The transmission of the force of turning) is good. The inclination of the first inclined subplane 14 as well as the opposite second inclined subplane 15 allows for a good transfer of the used blow force so that the clamp 1 can be sufficiently tightened or relaxed in a single stroke. And the striking force is converted to the turning movement of the clamping jaw 4 to be more effective than in the embodiment of FIGS. 1 to 3. The reason for this is that the displacement of the application point 6 when the component of the force in the direction in which the clamping jaw extends at the application point 6 where the wedge 7 is applied to the clamping jaw 4 simply becomes wider. This is because it becomes substantially larger than what is applied to. The component of the force acting in the direction of the clamping jaw enables the lever arm to pivot the clamping jaw directly with respect to the swing bearing 5. Therefore, the force causing the shaking can be limited to a considerable extent.

The clamps 1 allow the forming panels arranged in parallel in a plane to be connected at the edge webs 3 which form the rim of the panels, for this purpose being pivoted between each other and with respect to the support 8 with the aid of the wedges 9. With two clamping jaws 4, which can be made and which can press the edge webs 3 together, the support 8 simultaneously forms a junction with the wedge 7. The clamping jaw has for this purpose an application point 6 on the second subplane side opposite the first subplane, which is spaced below the lever arm by a pivoting bearing 5 of the clamping jaw. These application points 6 are suitably disposed at the inner ends of the elongated guide slots 10 which open outwardly and provide lateral guidance of the wedge as the wedge moves. The direction in which the wedge extends and moves is a direction intersecting the extending direction of the pivot axis of the pivot bearing 5 for pivotally mounting the clamping jaw 4 to the support 8.
