Definitions

  • the invention relates to a clamping clamp with a rail and two tendons, at least one of which is displaceably mounted on the rail and can be fixed relative thereto by means of a tilting plate spring-loaded in the direction of a tilting position against the rail, and after pivoting this tilting plate against the spring loading into a non-tilting one Position is displaceable.
  • Such clamps are known to have the advantage that the displaceable tendon cannot slide back and forth freely on the rail, but is always fixed in relation to the rail by the spring loading of the tilting plate in the direction of the tilted position.
  • the tendon can only be freely moved when it is actuated, ie when the tilting plate is pivoted into its non-tilting position.
  • the object of the invention is to improve a tensioning blade of the generic type in such a way that the tensioning element can be moved freely without the intervention of an operator.
  • the advantages of tendons with spring-loaded canting plates are obtained and, on the other hand, it is additionally achieved that the tendons can be freely displaceable on the rail, this being even more advantageous compared to tendons with self-tilting guides, since the inventive elements are displaced Tendons an undesirable self-tilting of the tendons cannot occur, as is often the case with self-tilting guides. Consequently In the clamp according to the invention, the tendon is either completely displaceable on the rail or fixed at a certain point by the tilting plate.
  • a tilting plate which can be locked in the non-tilting position.
  • a latch can be provided which engages over the tilting plate in its non-tilting position and holds it there.
  • a locking element which is displaceable transversely to the rail is provided, on which the tilting plate is supported in its non-tilting position, so that pivoting back into the tilting position is not possible.
  • a further improvement of this embodiment provides that the locking element can be moved parallel to the rail, so that the tilting plate can be pivoted into the non-tilting position by actuating the locking element.
  • the locking element can be moved parallel to the rail, so that the tilting plate can be pivoted into the non-tilting position by actuating the locking element.
  • FIG. 1 Another embodiment of the clamp according to the invention, in which an above-mentioned locking element is not absolutely required, provides that the tilting plate is displaceable in the direction transverse to the rail when pivoting into the non-tilting position and that a locking surface is assigned to the tilting plate and the corresponding tendon are which can be brought into contact with one another by moving the tilting plate transversely to the rail when pivoting into the non-tilting position and prevent pivoting back into the tilting position.
  • the play occurring when the tilting plate is pivoted from its canting position into the non-canting position with respect to the rail is used to bring two locking surfaces against one another by moving the tilting plate transversely to the rail.
  • a release in this very simple embodiment is made possible by the fact that an opposite displacement of the tilting plate in the context of the present game releases the two locking surfaces from each other again.
  • the latching element is designed as a holder for the tilting plate.
  • a locking of the tilting plate in its non-tilting position is possible either by the fact that the locking element alone is displaceable parallel and transversely to the rail, or else in that, in addition, the displaceability of the tilting plate itself is utilized relative to the rail in the non-tilting position.
  • the latching surface assigned to the tilting plate must of course be provided on the latching element.
  • the locking surface can in principle be assigned to all areas of the respective tilting plate. However, it is particularly advantageous if the latching surface is assigned to an area of the tilting plate which lies opposite an area acted upon by the tensioning element in the tilting position of the tilting plate.
  • the latching surface can also be arranged directly on the tilting plate in this exemplary embodiment. In any case, however, as large a lever arm as possible arises between the position of the latching surface and the contact of the tilting plate on the tendon, so that the forces acting on the latching surface can be kept low.
  • the tilting plate in its tilted position relative to the rail is a precisely defined position has to take in order to tilt correctly against this, but an exact guidance of the locking element which guarantees this tilting position is very expensive, it is advantageous if the tilting plate is mounted on the locking element with play, so that the locking element need not be exactly guided and due to the game the canting plate can assume the tilting position without interference from the locking element.
  • a particularly simple mounting of the tilting plate is possible in that the tilting plate with the area assigned to the locking surface is immersed in a recess of the locking element.
  • the latching element For actuating the latching element, it is advantageous in all exemplary embodiments in which such a use is used if the latching element has grip pieces for actuating.
  • a first exemplary embodiment of a clamping clamp according to the invention designated as a whole as 10 in FIG. 1, shows in detail a first clamping member 12 and a second clamping member 14, both of which are displaceably and fixably guided on a rail 16.
  • Both the first tendon 12 and the second tendon 14 each comprise a guide part 18 or 20 which is displaceable on the rail 16 and, as later described, can be determined.
  • An arm 22 or 24 extending from the rail 16 is integrally formed on this guide part 18 or 20, which in the case of the first tendon 12 on its side facing the second tendon 14 extends essentially transversely to a longitudinal direction of the rail 16 carries the first clamping surface 26, while the arm 24 of the second clamping member 14 has a threaded bore 28 running essentially parallel to the longitudinal direction of the rail 16, in which a spindle 30 is received, which in turn has a thrust piece 32 at its end facing the first clamping member 12 a second clamping surface 34 which runs essentially parallel to the first clamping surface 26 and faces it.
  • a displacement of the second clamping surface 34 in the direction of the first clamping surface 26 is possible by rotating the spindle 30 by means of a handle 36 arranged on an end of the spindle 30 opposite the pressure piece 32.
  • the two guide parts 18 and 20 are of identical design and are arranged in mirror image to one another on the rail 16.
  • Each of the guide parts 18 and 20 has a plate 40 running parallel to a side surface 38 of the rail 16, from which a front transverse web 42 running transversely to the longitudinal direction of the rail 16 and a spaced-apart transverse web 42 also arranged transversely to the longitudinal direction of the rail Raise the rail-extending rear crosspiece 44.
  • Both the front cross piece 42 and also the rear crosspiece 44 each have an opening 46 or 48, which is adapted in cross section to a cross section of the rail 16 and thus guides the front crosspiece 42 or the rear crosspiece 44 on the rail 16, so that a total of each of the guide parts 18 or 20 on its front crosspiece 42 and its rear crosspiece 44 on the rail 16 can be shifted without tilting, ie the distance between the front crosspiece 42 and the rear crosspiece 44 is chosen so large that tilting, as is the case with ordinary clamping clamps are necessary to determine the tendons, can not occur.
  • the guide parts 18 and 20 and thus also the tendons 12 and 14 are fixed with respect to forces acting perpendicularly on the clamping surfaces 26 and 34, respectively, by means of two tilting plates 50 and 52 arranged one above the other between the front transverse web 42 and the rear transverse web 44, each of which one Openings 53 and 54 penetrated by the rail 16, the openings 53 and 54 being dimensioned such that their edges 55 and 56, which extend transversely to the side surfaces 38 of the rail 16, then act on the rail 16 when the guide plate 50 or 52 are aligned along a canting diagonal of the rail 16 and are thus in their canting position, as is shown for the first tendon 12 in FIG. 1 and in FIG.
  • a U-shaped compression spring 58 is provided, which engages around the rail 16 with its two legs 60, so that each of the legs 60 runs parallel to a side surface 38 of the rail 16.
  • the legs 60 are in turn bent into a V-shape and are supported on the one hand on a side of the rear crossbar 44 facing the front crossbar 42 to the side of the opening 48 and on the other hand they press on the canting plate 52 facing the rear crossbar 44 and also act on the canting plate via this 50 so that both canting plates 50 and 52 remain parallel to the canting diagonal in the canting position.
  • the two canting plates 50 and 52 are received in a holder 64 which comprises a plate-shaped part 66 which bears on the side of the canting plate 52 facing the rear crosspiece 44.
  • a grip part 68 is formed on the side opposite the pressure lug 57, which extends along a lower edge 70 of the front transverse web 42 running parallel to the longitudinal direction of the rail 16 in the direction of the opposite tendon.
  • the grip part 68 On its side facing the lower edge 70, the grip part 68 has a recess 72 which, in its longitudinal extent, corresponds approximately to the extent of the lower edge 70 of the front transverse web 42 in the longitudinal direction of the rail 16.
  • the grip part 68 is displaced so far away from the lower edge 70 that the recess 72 does not encompass it positively, but rather that the grip part 68 has a side of the recess facing the canting plate 50, 52 72 formed step 74 stands on the lower edge 70 of the front crosspiece 42.
  • the plate-shaped part 66 which rests on the tilting plate 52, also has an opening 76 through which the rail 16 extends.
  • this opening 76 need not be adapted to the cross section of the rail 16, but can be chosen to be substantially larger than this.
  • two slits 78 are incorporated into the plate-shaped part 66 to the side of the opening 76, through which the compression spring 58 with its legs 60 extends can extend through from the rear crosspiece 44.
  • the slots 78 are followed by grooves 80 which run along the opening 76 and which accommodate the areas 62 of the legs 60 which act on the tilting plate 52, so that the plate-shaped part 66 can rest against the tilting plate 52 over the entire surface.
  • the canting plates 50 and 52 are loosely inserted into the holder 64, an end of these plates 50 and 52 lying on the opposite side of the pressure lug 57 extending into a recess 82 which is flush with a surface 84 of the plate-shaped part facing the plate 52 66 connects and passes through the handle 68.
  • two cheeks 86 rising up to the side of the canting plates 50 and 52 are provided, which laterally engage around the two canting plates 50 and 52.
  • the grip part 68 of the holder 64 can now be moved against the rear crosspiece 44 so far that the step 74 no longer lies against the lower edge 70 of the front crosspiece 44, but that the grip part 68 with its recess 72 is the lower edge 70 of the front crosspiece 42 embraces.
  • the surface of the step 74 running perpendicular to the lower edge 70 acts as a latching surface 88, which against a rear side 90 of the rear transverse web 44 facing the front whose crossbar 42 abuts.
  • the holder 64 is still supported on the rear crosspiece 44 with its end of the plate-shaped part 66 opposite the handle part 68.
  • the compression spring 58 also endeavors to place the canting plates 50 and 52 against the pressure lug 5, which in the described position of the holder 64 due to the displacement of the ends of the canting plates 50 and 52 in the recess 82 in the direction of the rear transverse web 44 from the Tilt diagonal are tilted out and thus no longer attack with their edges 54 and 56 on the rail 16.
  • the tilting plates 50 and 52 are thus in their non-tilting position and therefore allow the guide parts 18 and 20 and consequently also the first tendon 12 and the second tendon 14 to be freely displaceable.
  • the non-canting position can be achieved by an operator moving the grip part 68 in the direction of the rear crosspiece 44, indicated by the arrow 92, is displaced so far that the latching surface 88 engages behind the front crosspiece 42 and lies against the rear side 90 thereof.
  • the Ver edging plates 50 and 52 in their non-canting position.
  • the non-canting position is released by pressing on the end of the plate-shaped part 66 opposite the handle part 68 in the direction of the arrow 94, so that the latching surface 88 of the step 74 slides along on the rear side 90 of the front transverse web 44 until the latching surface 88 no longer finds a hold on the rear side 90 and, as a result of the action of the compression spring 58, the entire handle part is moved away from the rear crossbar 44 opposite the part 92, the step 74 abutting the lower edge 70 of the front crossbar 42 and sliding along it .
  • the ends of the canting plates 50 and 52 stuck in the recess 82 can again move so far in the direction of the front transverse web 42 that the canting plates 50 and 52 are again aligned along the canting diagonals and the guide parts 18 and 20 when acted upon by the pressure lug 57 set against the rail 16.
  • FIGS. 5 to 7 the same reference numerals are used for parts identical to the first embodiment. With regard to their description, reference is made to the description of the first exemplary embodiment.
  • the two tilting plates 50 and 52 are also in a holder 100 recorded, which is, however, configured differently from the holder 64 of the first embodiment.
  • the holder 100 comprises a plate-shaped part 102 which bears on the side of the tilting plate 52 facing the rear crosspiece 44.
  • a grip piece 104 is formed on this plate-shaped part 102, which extends along the lower edge 70 of the front transverse web 42 and is step-shaped on its side facing the lower edge 70, the step starting from the plate-shaped part 102, which extends parallel to the lower edge 70, a first surface 106 which adjoins this and extends away from the lower edge 70 perpendicular to this second surface 108 and a third surface 110 which adjoins this second surface 108.
  • a support 112 which extends in the direction of the rear crosspiece 44 and has a stop surface 114 running parallel to the rear crosspiece 44, is formed on the plate-shaped part 102 opposite the handle 104.
  • This support 112 limits with its stop surface 114 a displacement of the holder 100 in the direction of the rear crosspiece 44, so that it can only be displaced in the direction of the arrow 92 until the second surface 108 faces the rear side 90 of the rear crosspiece 44 engages behind the front transverse web 42 and thereby the entire holder 100 holds the tilting plates 50 and 52 in their non-tilting position, as shown in FIG. 7.
  • the holder 100 has between the handle 104 and the support 112 a recess 116 which is flush with a surface 118 of the plate-shaped part 102 facing the plate 52 and into which the recess 116 is located on the opposite side of the pressure lug 57 lying end of the plates 50 and 52 extends.
  • the plate-shaped part 102 is provided with a lug 120 which overlaps the two plates 50 and 52 in the region of the end on this side and bears against the surface 118.
  • the canting plates 50 and 52 are fixed in the region of their ends overlapped by the nose 120 by lateral cheeks 122 rising from the plate-shaped part 102, so that the ends of the canting plates 50 and 52 cannot slip sideways.
  • the tilting plates 50 and 52 are thus displaceable in the longitudinal direction of the plate-shaped part 102 parallel to the surface 118, but are otherwise fixed.
  • the plate-shaped part 102 has an opening 124 through which the rail 16 extends.
  • two slots 126 are machined into the side of the opening 124 in the plate-shaped part 102, to which grooves 128 running along the opening 124 are connected. These serve to receive the areas 62 of the legs 60 which act on the tilting plate 52. that the canting plates 50 and 52 are created on the one hand by the nose 120 and on the other hand by the recess 116 against the surface 118 of the plate-shaped part 102, the areas 62 of the legs 60 of the legs 60 of the compression spring 58 which act upon the canting plate 52 are also held in a form-fitting manner in the grooves 128 .
  • the holder 100 therefore forms, together with the tilting plates 50 and 52 and the compression spring 58, an assembly unit in which the compression spring 58 is firmly integrated.
  • a grip surface 130 is formed on the handle 104 opposite the third surface 110 on an outside. Furthermore, the plate-shaped part 102 is also provided with a grip part 132 in the region of the nose 120.
  • this canting is released by acting on the holder 100 via the gripping surface 130 in the direction of the arrow 92.
  • the entire holder 100 is displaced in the direction of the rear transverse web 44 , wherein the first surface 106 slides along the lower edge 17 of the front crossbar 42 until the entire holder 100 is displaced in the direction of arrow 92 so far that the second surface 108 can engage behind the rear side 90 of the front crossbar 44 and thus a different Exercise of the entire holder 100 against the arrow 94.
  • the canting plate 50 and 52 Due to the action of the canting plate 50 and 52 by the compression spring 58, the canting plate 50 is still in contact with the pressure lug 57, so that the entire holder 100 is tilted in the last-described position relative to the starting position. This position described last corresponds to the non-canting position of the canting plates 50 and 52.
  • the canting plates 50 and 52 with their ends facing the pressure piece cannot lift off from the plate-shaped part 102, ie from its surface 118. but because of the nose 120, the entire plate-shaped part 102 and thus also the holder 100 tilt.
  • the stop surface 114 on the support 112 prevents the holder from being overpressed when the holder 100 is pressed in the direction of the arrow 92, i. shifting in the direction of the rear crosspiece so far that the entire handle 104 comes to lie behind the rear side 90 of the front crosspiece 92. That is, the position of the stop surface 114 is selected so that after reaching behind the rear side 90 of the front crosspiece 42 through the second surface 108, only a slight displacement of the holder 100 in the direction of arrow 92 is possible, the holder 100 with slides along the third surface 110 on the lower edge 70.
  • the non-canting position of the canting plates 50 and 52 is released by applying pressure the holder 100 in the region of the handle part 132 in the direction of the arrow 94, as a result of which the second surface 108 on the rear side 90 of the front transverse web 42 slides along until the first surface 106 on the lower edge 70 can move against the arrow 92.
  • the holder 100 and thus also the tilting plates 50 and 52 are tilted back into the tilting position.
