Definitions

  • the invention relates to an exhibitor, comprising two arms, which are hinged at one end to another around a common hinge axis and, at the opposite end, work individually with a fitting part, one of which is attached to a frame and the other to a wing which can be displaced with respect to that frame can be attached, which arms are hinged between a folded stand, in which they are basically parallel to each other, and a folded-out stand, each fitting part is attached to the associated arm via an adapter, each adapter is rotatable on the one hand about an axis of rotation, which runs transversely on the common hinge axis of the arms, in such a way that, when the arms are folded in, those axes of rotation are parallel or coincident and the arms can be rotated between a bolt position and an unlocked position, each intermediate piece on the other hand is hingeable about a hinge axis, and the hinge axles on the one hand and the common hinge axis of the arms on the other hand are mutually parallel in the unlocked position of the arms.
  • a window such as a skylight
  • the exhibitor In the open stand, the exhibitor must protect the window from being opened too far. When the stand is closed, the exhibitor must be able to provide the necessary resistance to attempted break-ins.
  • the purpose of the invention is to provide an exhibitor that has proven itself better. This purpose is achieved by the intermediate piece or the fitting part of one of the arms on the one hand, and the other arm and the associated fitting part, on the other hand, carry blocking parts for blocking the exhibitor when the arms are folded.
  • the exhibitor is blocked as soon as the arms are folded in. This means that even if you forgot to turn your arms into the bolt position, you can still secure yourself against attempts to break in. It is also important that the frame and the sash are no longer connected indirectly via both intermediate pieces, but more directly via one or both fitting parts.
  • the blocking parts can be locked with respect to one another by rotating the folded arms from the unlocked to the locked position.
  • These blocking parts can be designed in all sorts of different ways.
  • the intermediate piece or the fitting part of one of the arms comprises a locking pin, the other arm or the associated intermediate piece or the fitting part comprising a cavity which cooperates with the locking pin at least in the folded-in position of the arms.
  • the locking pin and the cave can have a cylindrical shape.
  • the diameter of the locking bolt can be several times larger than the diameter of the sheet material from which the arms of the exhibitor are made.
  • the locking pin is preferably an extension of the hinge axis between the fitting part and the associated intermediate piece.
  • the exhibitor can only collapse by pushing the material off the locking pin or by flowing the material from the inner wall of the cave as a result of excessive surface pressure.
  • Resistance to forcing can be further increased if the extension includes one or more contour grooves (grooves or serrations, for example) that increase the resistance between the surface of the locking pin and the inside of the associated cavity in the event that the locking pin is strong against the inside the cave is pressed.
  • contour grooves grooves or serrations, for example
  • one of the arms can comprise a locking lug and the other arm or the associated intermediate piece or fitting part can comprise a locking surface which cooperates with the locking lug at least when the arms are in the locked position.
  • At least one of the arms of the exhibitor can have a U-shaped average, so that when folded, the inner arm is located between the legs of the U-shaped arm.
  • the locking nose can be located on one of the legs of that inner arm.
  • the arm is known to be connected to an intermediate piece by means of a rotation axis running transversely on the common hinge axis of the arms, which is connected by means of a hinge axis running transversely on that axis of rotation to a fitting part which can be attached to a frame.
  • a locking surface is preferably provided on the intermediate piece, such that when the arms are in the locked position, the locking surface hooks behind the locking edge.
  • the locking lug is elongated and is directed with its longitudinal direction to the longitudinal direction of the inner arm, the locking surface is designed as an extension of the intermediate piece such that when turning the folded arms in the bolt stand, the locking surface is behind the locking nose hooks.
  • the exhibitor can be executed with a cave that is undercut and the locking bolt is a safety projection has, so that when the arms are twisted from the unlocked to the locked position, the locking projection is secured in the undercut cavity.
  • the locking parts can comprise hooks.
  • the hooks coming into cooperation with one another as soon as the arms of the exhibitor are folded in is designed in such a way that the fitting part of one arm has a hook and the intermediate piece of the other arm has a hook, which hook in the folded state the arms interlock to lock the exhibitor.
  • the fitting part of the arm provided with a hook can be attached to the window frame, so that the intermediate piece belonging to the other arm can be blocked directly and straightforwardly with respect to that fitting part and thus to the frame.
  • the fitting part provided with a hook is connected to the associated intermediate piece by means of a hinge axis running transversely on the common hinge axis of the arms, which in turn is connected in parallel to the corresponding arm on that common hinge axis, so that when the arms are folded the hooks of that fitting part lies outside the area determined by the parallel hinge axes.
  • the hooking into one another in a locking manner takes place during the last phase of the folding-in movement.
  • the hooks are brought outside the mutual contact surface during the initial phase of the folding out of the arms, after which the further folding out and opening of the wing can take place.
  • This behavior is made possible by the mutual positioning of the hinge pieces and the hook on the fitting part.
  • Figure 1 shows a side view of the window display, seen obliquely from below, in the event that it is in a half-folded position.
  • Figure 2 shows a side view of the window display in the event that this is in the extended position.
  • Figure 3 shows a side view of the window display in the event that it is in a half-folded position.
  • Figure 4 shows a partially broken side view of the window display in the event that it is in the locked locked position.
  • FIG. 5 shows a partially broken top view of the window opener according to V-V of FIG. 4.
  • Figures 6a - 6c show a variant, in different phases of folding.
  • the window display 1 shown in FIG. 1 comprises two arms 2, 3, two fitting parts 6, 8, two cover plates 5, 7 and two intermediate pieces 17, 18.
  • the window display 1 otherwise comprises a finger grip 4, an outer profile 2 and an inner profile 3.
  • the window display 1 must be mounted on a rotating sash with the fitting part 6 and on a window frame with the fitting part 8.
  • the finger grip 4 is attached to the outer arm 2.
  • the outer and inner arms 2 and 3 are rotatable with respect to each other via the hinge axis 12.
  • the outer and inner arms 2 and 3 are rotatable with respect to their associated intermediate pieces 18 and 17 via the hinge axis 10 and 15, respectively.
  • the intermediate piece 17, 18 is in terms of its associated fitting part 8 or 6 via the hinge axis 9 or 11 rotatable.
  • the cover plates 5, 7 are attached to the associated fitting parts 6 and 8; they serve to beautify them.
  • the fitting part 8 or the intermediate piece 17 comprises a locking pin 16, the axis of which coincides with that of the hinge axis 9.
  • the intermediate piece 18 or the outer arm 2 comprises a cavity 19, the axis of which coincides with that of the hinge axis 10.
  • the locking pin 16 has been designed in such a way that it fits exactly into the cavity 19, in the event that the window lock is in the position shown in FIGS. 4 and 5.
  • the inner arm 3 comprises a locking lug 14.
  • the intermediate piece 18 comprises a locking surface 13 on at least one side.
  • the locking surface 13 has such a shape that it fits exactly under the locking lug 14 when the window opener is in the folded, locked position, as shown in FIGS. 4 and 5.
  • the fitting part 8 preferably comprises a locking surface 13 on both sides.
  • the locking projection which is not used for hooking behind the locking edge, can serve as a starting point for the rotary movement of the intermediate piece 18 and the fitting part 6 with respect to the outer profile 2.
  • the two legs of arm 2 are of equal length, so that the window opener can be locked both to the left and to the right.
  • a cover cap 22 can be provided, which removes the axis 10 from view.
  • the window display is suitable for locking to the right.
  • the window display can be fixed in a medium-sized company.
  • the locking pin 16 can carry one or more locking projections 20, the cavity 19 then being undercut at 21 and having axial grooves 23.
  • the securing projections slide into the undercut cavity 21 via the axial grooves 23.
  • the securing projections are secured in that cavity 21: see FIGS. 4 and 5.
  • the window display shown in FIGS. 6a-6c is equipped with a fitting part 25 which can be attached to the window frame and carries a hook 26.
  • the fitting part 6, which can be attached to a window works together via a hinge axis 15 with an intermediate piece 27, which is also provided with a hook 18.
  • a locking pin 16 is also provided on the fitting part 25 and a recess 19 in the intermediate piece 27.
  • the hook 26 is located under the area determined by the hinge axes 12, 15.
  • This position of the hook 26 is a result of the shape of the intermediate piece 17, namely its leg 29 and the chest 30 of the fitting part 25.
  • the distance a 2 between the hook 26 when the arms 2 , 3 are folded in is less than the distance a 1 , which occurs in a slightly unfolded position, as in Figure 6b is reproduced. In that state, hook 2b and hinge axes lie approximately on the same surface.
