Definitions

  • the invention relates to a device according to the preamble of claim 1 for attaching tear lines for the miter cut to the frame and profile frame, as e.g. can be used for window, door and picture frames.
  • the invention has for its object to provide a device with which these disadvantages can be overcome and which enables the determination of the exact position of a miter cut quickly for any type of arched, arched frame or window, as well as for slanted windows and gable windows.
  • the tear-open device should be easy to disassemble and reassemble for use on construction sites.
  • the configuration of the device according to the invention makes it possible in a simple manner to set both the width and the height of a window on the tear-open device, in order then to use the frame pieces, e.g. for the window frame or window sash, use the tab attachment to determine and mark the position of the miter cut lines.
  • the invention provides a deduction template, which can be placed on the scale point corresponding to the window height on the two parallel legs, and with which the position of the miter cut line on the outer edge of the frame or Profile frame is easy to tear, the course the miter cut line is fixed, because if the frame is assigned to the crossbar at right angles, a 45 ° angle can easily be set on the saw.
  • FIG. 1 shows a tear-open frame 14 according to the invention, which consists of three straight legs 1 to 3, each of which is provided with a measuring scale 7 for determining distances and is movable relative to one another.
  • a detachable rider attachment 4 with protractor 5 and ruler 6 can be placed on the legs designed as guide rails.
  • a side view of the tear-open ruler is shown in Fig. 4 and shows the assignment to the leg on which the rider attachment is slidably arranged.
  • the two legs 1 and 3 of the tear-open frame 14 are aligned parallel to one another and are displaceable relative to one another.
  • the third leg 2 of the Aufr discloserabmens 14 is perpendicular to the legs 1 and 3.
  • the leg 2 rests with one end face perpendicular to the leg 1, while the leg 3 in turn abuts vertically with one end face on leg 2.
  • the leg 2, together with the leg 3 lying vertically against it, can be displaced along the leg 1, the three legs being fixed by suitable locking devices, such as clamps, clamping springs or tensioning screws, in any configuration which arises from the perpendicular or parallel displacement of the individual legs be able to accommodate profile frame pieces of different sizes.
  • each leg 1 to 3 of the tear-open frame 14 is provided with a longitudinally extending groove 8 for guiding the rider attachment 4 which can be moved between the individual legs 1 to 3.
  • the shoe 9 of the rider attachment 4 running in the groove can be geometrically matched to the cross section of the groove in such a way that it is easily tilted in any rest positions and thus jammed to keep it secure during the Attaching the elevation to position.
  • the shoe 9 of the rider attachment 4 and the groove 8 can also be secured using suitable locking devices, e.g. Clamps, clamping springs or clamping screws, which enable the rider attachment 4 to be securely fixed at any position in the grooves 8.
  • FIG. 1 A high level of user friendliness can be achieved with the currently preferred embodiment of the device according to the invention shown in FIG. 1.
  • a multi-rib support frame frame consisting of support frame bars 12 running parallel or perpendicular to one another with attached auxiliary scales for determining the distance 11, is used to support the tear-open frame 14.
  • the support frame 10 can be designed so that some or all of the spars 12 are mutually displaceable.
  • auxiliary scales 11 additionally attached on the one hand offer greater flexibility and convenience in the precise alignment of the legs 1 to 3 and the frame pieces 13 to be cut to size, and on the other hand the operator is given the option of also gripping the frame from below in order to attach tear-open points from below.
  • a circularly curved frame section 15 for an arched window with the width a is placed on the tear-open frame 14 and aligned such that the intersection points A and A ′′ ′′ and B and B ′ of the outer and inner edges of the frame section 15 also the inner edges of the legs 1 and 3 of the tear frame certain distances DA and D 'B are of equal length, so that the leg 2 of the tear frame 14 is tangent to the apex C of the circularly curved frame section 15.
  • the apex C thus also divides the distance D D 'formed by the intersection points D and D' of the inner edges of the legs 1 and 2 or 2 and 3 into equal parts.
  • the miter cut line A S which makes it possible to connect the straight frame piece 18 to the section of the curved frame section 15 or of the stitch arc determined by the circular arc section B C A.
  • Break-open points A and S are obtained as intersection points between the outer and inner edges of the curved stitch arch 15 with the left and right edges of the straight frame piece 18. This allows you to mark the two tear points A and S directly on the curved arch.
  • the frame height x is significantly lower than the height h of the tear-open frame 14, however, when the solder falls from the intersection A or S of the curved frame section to the vertically underneath tear-open points A '''' and S 'on the straight frame piece 18 Transfer errors come. If the frame height x is greater than the height h of the tear-open frame 14, this does not pushing the straight frame piece 18 directly under the curved frame section 15 anyway.
  • a frame 16 is used as an aid, the height of which corresponds to the height h of the legs 1 to 3 of the tear-open frame 14, and whose width a corresponds to the width of the straight frame piece 18 to be cut or the curved frame piece 15.
  • This frame 16 can now be pushed under the curved frame section 15 resting on the tear-open frame 14, and in addition to the first tear-open point A, the second tear-open point S necessary for fixing the miter cut is obtained directly on the curved profile frame as the point of intersection between the inner edge of the curved frame section 15 and the right edge of the frame 16.
  • the miter cut line A S can be drawn directly on the curved frame section 15 by means of the tear-open ruler 6.
  • the angle ⁇ between the left-hand edge of the straight frame piece 18 and the miter elevation A '' '' S ' can be read off directly and held so that the angle ⁇ when the straight frame piece 18 is clamped onto a saw, which is not shown, can be set directly on the stop bar of the saw.
  • FIG. 2 shows the same method for determining the position of the miter cut line B '' T for a straight window wing frame section 19 to be connected to the circular arc section A '' C 'B' 'of the curved window sash branch arch 20.
  • FIG. 3b show the tearing open of the two possible miter cut lines on the window sash frame sections 19 and 21, and the U-shaped window sash frame 22 of an arched window.
  • the U-shaped, in its curvature section circularly curved window sash frame 22, as shown in Fig. 1, is aligned with its straight legs parallel to the legs 1 and 3 of the tear-open frame so that the leg 2 of the frame tangentially at the apex of the circular portion of the frame abuts.
  • the center axis m of the circular arc can be defined by means of the scale of dimensions applied along the leg 2.
  • the distances e and f from the straight lines i, j, k and l running parallel to the central axis m result from the width b of the window sash and the rebate air gap c of the window sash frame sections 19 and 21 which results in the desired overlap.
  • These straight lines i, j, k and l can be defined on the window sash frame 22 by means of the rider attachment 4 which can be displaced on the leg 2 together with the protractor 5 and tear-open ruler 6, the assignment of which to the frame and sash profile is shown in FIG. 4.
  • the points S and T or U and V defining the position of the miter cut lines ST and UV are thus obtained as intersection points of the straight lines k, i, j and l with the inside and outside edge of the curved window casement frame 22.
  • these intersections can be drawn directly.
  • the cut edge angles ⁇ and ⁇ to be set on the saw are determined with the aid of the protractor 5 and the tear-open ruler 6.
  • the tear-open device can also be used to produce the miter elevations for inclined windows or gable windows in a corresponding manner, in that the inclined frame sections are applied to the tear-open frame in accordance with the U-shaped frame sections or the stitch arch.
  • the miter elevations are also applied in a corresponding manner for windows in the face-to-face design, the center of the faceplate coinciding with the central axis m, and the straight window sash frame sections and, accordingly, the miter elevations further apart.
  • 5a and 5b is an application of the tear-open device for determining the position of the miter cut lines shown in order to adapt the position of the lower cross member of a window sash to the position of the frame cross member given by the window height.
  • the point E results from the window height shown on the scale 7 on the leg 1 of the tear-open frame. Since the frame cross member runs at right angles to the straight frame piece 18, there is a miter cut line at 45 ° through this point E. This miter cut line can be made using the protractor 5 and the scribe 6 are marked.
  • a deduction dimension dependent on the profile material used can be removed from point E.
  • a template 26 is provided, which has a width corresponding to the deduction dimension. This makes it easy to determine point F as the starting point for the position of the miter cut.
  • the use of these deduction dimension templates which are individually dimensioned for the respective type of window casement frames, represents a considerable time saving compared to marking with a protractor and scribing ruler.
  • the support frame spars 12 of the support frame 10 are provided with scales, all dimensional adjustments can be made without the aid of a separate scale.
  • the tear-open frame and the support frame are designed to be easily dismantled and assembled again.
