Definitions

  • the invention relates to a connection fitting for mutually bracing and gluing in particular plate-shaped wooden parts on their abutting surfaces, such as e.g. Door linings in the mitred corners, consisting of one end with a tensioning device and the other end with a counter-pulling angle in primarily rear recesses, for example pot holes, of the metal brackets engaging with the wooden parts to be connected.
  • a connection fitting for mutually bracing and gluing in particular plate-shaped wooden parts on their abutting surfaces, such as e.g. Door linings in the mitred corners, consisting of one end with a tensioning device and the other end with a counter-pulling angle in primarily rear recesses, for example pot holes, of the metal brackets engaging with the wooden parts to be connected.
  • a connection fitting of the aforementioned type shown in DE-GM 80 28 657 has a tensioning device in which a holding arm of the metal bracket, bent at right angles, has a tensioning screw provided with a movable tensioning plate in a centrally arranged threaded bore records. Due to the parallel position of this clamping screw to the web of the metal bracket, it is inevitable that a screwdriver opening leads from the outside of the one wooden part to its cup hole in order to be able to actuate the clamping screw. However, such outside and consequently visible openings are not always to be made and are often undesirable, which is a considerable disadvantage of the known fitting.
  • DE-GM 80 28 657 also proposes the use of eccentrically mounted clamping bodies to be inserted into the pot bores at the rear.
  • a disadvantage in the use of such connection fittings is their inadequate clamping force, which is due to the considerable circumferential friction the clamping body can only be applied to a limited extent with these.
  • the contact pressure to be achieved between the two wooden parts is not sufficient for careful mutual gluing, since the glue joint can only be closed incompletely.
  • the object of the invention is, based on the aforementioned prior art, to provide a connecting fitting which avoids the previous disadvantages by working without screwdriver openings which have a disturbing effect, but nevertheless ensures an extremely powerful contact pressure in the gluing area of the wooden parts.
  • the invention mainly proposes that the set screw be inserted into the fold of the metal bracket to form an acute angle with the web.
  • This simple measure makes it possible, in contrast to the older connection fittings already equipped with clamping screws, to dispense with any openings in the visible surfaces of the wooden parts, since the set screw of the novel fitting part can be actuated effectively from the back of the wooden parts.
  • the fold of the metal bracket used to hold the set screw is obtuse from whose web runs out, the mounting of the threaded hole intended for the set screw is facilitated by its right-angled course in the fold. If the adjusting screw is also a fine-thread screw, the contact pressure in the glue joint can be increased even further.
  • Additional features of the invention also serve to make the fitting as versatile as possible, easy to assemble and claw-like.
  • the latter is intended to cause both the tendon and the counter-pulling angle to engage in the bottom area of the cutouts, so that the tensioning force of the fitting primarily affects the front of the wooden parts and consequently their perfect compression is achieved at this particularly important point.
  • the wooden parts 1 and 2 shown in FIGS. 1 and 2 of a door panel are provided with mitred ends with pot holes 3 on the rear. These pot holes 3 serve to receive the connection fitting, which consists essentially of a metal bracket 4 and is designed according to the invention.
  • the metal bracket 4 which can also be seen in the perspective view in FIG. 3, has a counter-pull angle 5 at one end, which forms an acute angle with the web 6 of the metal bracket 4. At the other end, it has a bevel 7, in which is a set screw 8 formed primarily as a fine thread screw. The latter is directed against a tendon 9, which is articulated loosely and in a pendulum-like manner on the metal bracket 4, in that it extends according to FIG.
  • connection fitting Another area of application for using the connection fitting described above is e.g. the preparation of countertops for kitchen furniture. It is also important there that they can be connected to one another quickly, invisibly and under high contact pressure at all types of joints.
