Definitions

  • the invention relates to a device for spreading a window sill with two clamping elements which can be displaced in relation to one another in a spreading direction and can be fixed in a spreading position and which form clamping jaws on the free end sections.
  • Devices for spreading window sills are known from the prior art. These usually include two clamping elements made of metal, which are designed as a hollow profile. This enables the second clamping element to be slidably mounted in the first, so that a telescopic connection is created. Both clamping elements have bores spaced apart from one another along their longitudinal axis transversely to the direction of expansion, so that the clamping elements can be fixed in an expanded position with the aid of a cotter pin, which engages in the overlapping bores.
  • a disadvantage of the prior art is that the clamping elements can only be fixed if the bores of the clamping elements overlap and a form fit can be established via the cotter pin.
  • the available space in the expansion direction is specified by the window sill and, for example, the opposite window reveal and allows very little play. If the device is clamped between the window sill and, for example, the window reveal for spreading the window sill, the applied pressure is given by the overlapping of the bores and can hardly be changed by the user.
  • Clamping elements made of metal are also known from the prior art, which are clamped together via a locking screw in order to enable more flexible positioning of the clamping elements.
  • the disadvantage of this, however, is that such a connection allows only low clamping forces due to the clamped connection.
  • the invention is therefore based on the object of designing a device for spreading window sills in such a way that it can be easily manufactured on site and the length of the device in the spreading direction can be continuously and reversibly shifted and fixed in spite of the high forces acting during operation.
  • the invention solves the problem in that the clamping elements are wooden beams, with one of the clamping elements forming a groove running in the direction of expansion, which forms a stop for a tongue of the other clamping element inserted into the groove in at least four spatial directions running transversely to the direction of expansion, and that one of the clamping elements is penetrated transversely to the direction of expansion by a locking screw that opens into the bottom of the groove.
  • the device can be fixed steplessly and reversibly by the user, depending on the required pressure, both by a frictional or clamping connection and by a positive connection. Because of the groove of one clamping element running in the direction of expansion, the clamping elements can be shifted in the direction of expansion.
  • the groove forms a stop for the spring in at least four spatial directions running transversely to the direction of expansion, the spring cannot be pulled out of the groove transversely to the direction of expansion because there is a form fit between the tongue and the groove in all directions in space transversely to the direction of expansion. If at all, the tongue can only be pulled out of the groove in the spreading direction. If the locking screw is turned in the first wooden beam in the direction of the groove base, the forces acting transversely to the direction of expansion fix the two clamping elements to one another when they come into contact with the second clamping element.
  • the screw can be screwed further into the second clamping element beyond the clamped connection that has been created, so that a positive connection is created that can absorb significantly higher forces without the two clamping elements shifting towards one another.
  • the clamping elements can be made of solid wood.
  • the clamping jaws can include wooden panels and be screwed to the clamping elements.
  • two or more locking screws can be provided in a clamping element along the spreading direction, which fix the two clamping elements to one another in an overlapping area.
  • the screw can have a wing head or a star grip, for example.
  • a threaded screw-in sleeve can be provided for the clamping element through which the locking screw passes so that spreading forces in the spreading direction can be introduced in a material-friendly manner into the clamping element through which the locking screw passes.
  • the tongue-and-groove connection between the clamping elements can be produced in a particularly simple manner in terms of production technology if the tongue and groove of the clamping elements have a dovetail-shaped cross section. Since the clamping elements are made of wood, the dovetail profile can simply be milled directly into the clamping elements without the need for additional components to create the tongue-and-groove connection.
  • the clamping elements are fixed in the spread position by turning the locking screw, the clamping elements must absorb high forces transversely to the spread position.
  • the locking screw pass through the tensioning element that has the spring.
  • the tensioning element having the spring generally has a greater length in the throughput direction of the locking screw than the tensioning element having the groove. Due to this longer length, the counteracting force acting when turning the screw can be introduced into the clamping element more evenly and thus more gently.
  • the clamping or positive connection is particularly easy to produce if the locking screw passes through the tensioning element that has the spring.
  • the width of the groove base can be at least half the width of the tensioning element having the groove.
  • the depth of the groove is at least one third of the depth of the clamping element having the groove. In this way, the effective surface of the clamping closure can be increased without making the clamping elements larger.
  • the tongue of the second tensioning element is dimensioned accordingly so that it can interact with the groove of the first tensioning element according to the invention, in particular the height of the tongue can correspond approximately to the depth of the groove.
  • a device according to the invention for spreading a window sill comprises two wooden beams as clamping elements 1, 2, which can be displaced against one another in a spreading direction 3.
  • the clamping elements 1, 2 In order to store the device more stably in the spread position and to introduce the acting forces more evenly into the window sill and the second, opposite supporting surface, the clamping elements 1, 2 have clamping jaws 4 at their free ends. So that the clamping elements 1, 2 can only be displaced relative to one another in the spreading direction 3 and are fixed transversely to the spreading direction 3, one clamping element 2 has a groove 5 running in the spreading direction 3, into which a spring 6 of the other clamping element 1 engages. The groove 5 forms a stop for the spring 6 in at least four spatial directions transverse to the spreading direction 3.
  • the groove 5 and the tongue 6 have a dovetail-shaped cross section, since these can be worked into the wood of the clamping elements 1, 2 with simple means.
  • a particularly good compromise between simple production and a good connection between groove 5 and tongue 6 can be achieved if the bottom and side walls of groove 5 enclose an angle of less than 85 degrees, preferably 75 degrees, in cross section.
  • the tongue-and-groove connection can be additionally improved by correctly dimensioning the groove 5 and the tongue 6 , for example if the depth of the groove 5 is at least one third of the depth of the tensioning element 2 having the groove 5 .
  • the tongue 6 of the other clamping element 1 is dimensioned to match the groove 5 . Additionally or alternatively, the width of the The bottom of the groove is at least half the width of the clamping element 2 having the groove 5 . If the distance between the window sill to be spread and the opposite support surface is large, it is recommended that both the groove 5 and the tongue 6 extend over the entire length of the respective clamping element 1, 2.
  • the two clamping elements 1, 2 After the two clamping elements 1, 2 have been moved against each other in the direction of expansion 3 so that the clamping jaws 4 exert sufficient pressure on the window sill and the opposite support surface, the two clamping elements 1, 2 are fixed in the expanded position.
  • at least one locking screw 7 is provided, which penetrates a clamping element 1 transversely to the direction of expansion 3 .
  • This locking screw 7 can have a wing head for easier operability. It is also advantageous if more than one locking screw 7 is provided, since this not only strengthens the clamping or positive connection, but also torques occurring in the spread position can be better introduced into the clamping elements 1, 2.
  • the locking screw 7 is rotated to fix the clamping elements 1, 2 in the spread position in the clamping element 1, so that it moves transversely to the spreading direction 3 in the direction of the groove base of a clamping element 2. From the contact of the locking screw 7 with the clamping element 2, the two clamping elements 1, 2 are pushed apart transversely to the spreading direction 3, whereupon a clamping connection between the two clamping elements 1, 2 arises due to the tongue and groove connection. If higher spreading forces are required than can only be maintained via such a clamping connection, the locking screw 7 can be turned further so that it penetrates the clamping element 2 and creates a positive connection.
  • the locking screw 7 preferably passes through the clamping element 1 with the spring 6.
