Definitions

  • the invention relates to a ceiling outlet with outlet slots, which are formed in a sheet, a steel plate or a plate of another material, which is cut in the contours of the ceiling outlet, and which are equipped with air deflection lamellas for blowing in air from an air duct system into a room .
  • Ceiling outlets of this type are known and are widely available on the market. Such outlets differ primarily in their shape, size and in the arrangement of the slots and the slats guiding the air flow.
  • outlets in which the outlet slots are arranged in a circular, row-like or similar manner, outlets with fixed and adjustable air deflection blades.
  • FR-A-2 313 641 for example a metal sheet, a steel plate or a plate of another material which is cut in the contours of the future ceiling outlet, outlet slots are punched in the desired and thus determined arrangement.
  • Appropriate bearings are attached by welding, gluing, screwing, clamping or the like after the punching out in order to fix, in particular, movable air deflection lamellas.
  • Such bearings preferably consist of small plates which have bores or the like as receptacles for axes, in particular for holding tubes, around which the air deflection blades are rotatably fixed.
  • Such platelets are produced in a separate working step, preferably by means of a corresponding stamping, the receiving openings for the holding tubes being formed in the same working step or in a further working step, depending on the tool.
  • these plates with the air deflection lamellae are preferably attached by clamping in the outlet slots.
  • Such holding plates are somewhat wider than the outlet slot for which they are intended.
  • they In a lower area they have a slot of equal length on both sides, running from the outside inwards, the width of the slot being the thickness of the sheet, the steel plate or the plate of another material corresponds.
  • the portion remaining between the slots has a width which in turn corresponds to the width of the outlet slot.
  • Platelets of this type are introduced longitudinally into the outlet slots in the plane of the slot and are guided over the sheet by rotating the slots until they are at right angles to the outlet slot.
  • the axles or the holding tubes with the slats are mounted in the receiving openings.
  • the holding plates have to be painted extra, which means a lot of work, as well as a remarkable environmental impact.
  • Ceiling outlets of this type therefore show considerable disadvantages both in the manufacture and in the maintenance and cleaning use.
  • the inventor has set itself the task of creating a ceiling outlet that is easy to use in use, especially for maintenance work, and is produced in a process that has a cost-effective, environmentally friendly and energy-saving effect.
  • a steel plate or a plate of another material is required, which corresponds in its contours to the shape of the later ceiling outlet, with as much material being permitted on the edge side as is necessary for the later folding of the edge sides.
  • This sheet is then punched and licked out, a tongue being left at the end when the outlet slits are punched out and protrude into the clear width of the outlet slit.
  • the outlet slots can be of different lengths, the tongues left in them are preferably the same size.
  • Tongues can be angular, but can also have a rounded triangular shape, which, however, requires a greater outlay in the production of corresponding tools.
  • the tongues are preferably bent at right angles with a special embossing tool.
  • the tongues protruding at right angles with the receiving openings each form the bearing for the axes of the air deflection slats.
  • the edge sides are preferably also bent over fold lines which correspond to the contours of the finished ceiling outlet.
  • the lamellae or the holding tube with the lamellae rotatable about them can easily be mounted and fixed in these bearings, simply inserting a lamella between two tongues and pushing the holding tube through the tongues or lamellae.
  • a ceiling outlet of the type described above has the advantage that it has no protrusions on the front, so that it can be easily cleaned with the nozzle of a vacuum cleaner.
  • outlets of the type mentioned are made of one piece before the lamellas are introduced, they can be completely powder-coated, which makes complex and environmentally harmful spray painting unnecessary.
  • Ceiling outlets of this type can be made square, round or in any other shape.
  • Figure 1 shows a flat sheet R, a steel plate or a plate of another material, in a stamped and licked out state.
  • the sheet metal When checking out, the sheet metal is released at its four corners and isosceles corner pieces 1, the legs 2 having a length which corresponds to the width b of laterally bent edge sides 3 according to FIG. 2.
  • Punching holes 4 and 4a are introduced into the sheet metal R, a preferably angular tongue 5 being left in the outlet slots 4 and 4a at both ends, which are opposite one another in the outlet slots. While the outlet slots 4 or 4a of a ceiling outlet can have different lengths l or l 1 as desired or as required, the tongues 5 always have the same length which corresponds to the later height h.
  • the tongues 5 are then bent or placed perpendicularly opposite a side 7 on the room side with a special tool (not shown) and form bearings 8 for axes 11 with the receiving openings 6. These axes 11 are formed by fastening tubes 9.
  • the fastening tubes 9 each penetrate opposite tongues 5 or their receiving openings 6 and are fixed there by corresponding embossments or widenings. In the position of use, the fastening tubes 9 reach through fins 10 which rotate about the fastening tubes 9. The emerging air flow can be influenced by appropriate rotation of the slats 10.
  • the edge sides 3 are preferably also bent in the same working step with the erection of the tongues 5.
