Definitions

  • louver type ventilators comprise a number of sliding movements and parallel mechanisms for the operating of same, which operating means easily becomes out of order.
  • One object of the present invention is to provide a ventilator. of the louver type, where the above mentioned disadvantages are not present, and generally speaking the invention consists in a method of hinging the individual plates, serving tea for the closing and opening of the ventilator in such away that they during the opening 'or .0105- ing process of the ventilator will pass through movements generally corresponding to the movements of the folding doors, used for instance'on vehicles for transportation of persons.
  • the ventilator according to this invention is constructed in such a way that pairs of plates are hinged together at the same time as one of each pair is hinged to the ventilator frame on the one side and to the other plate on the other side, while the latter plate is provided with a rigidly mounted rod or bar, which at'a suitable point, for instance and place itself over the former plate or aline itself with the former plate, respectively for th opening and closing of the ventilator.
  • This simple mechanism is constructed in' such a way that one may actuate either the plate which is hinged to the frame or the rod which is rigidly fixed tothe other plate, swinging either one of these through an angle of 90, and this movement will cause that both plates will shift position from being placed one above theother in the open position and alined adjacent to each other in the closed position of the ventilator.
  • a further objectof this invention is to provide suitable actuating means for hand operation of the ventilator which may be operated directly by hand as well as indirectly by means of a string to be pulled.
  • This actuating mechanism comprises a circular disk or sector which is adapted to actuate the plates by means of suitableconnecting rods, and which is provided with teeth or apertures which are in mesh with a pinion, 40 arranged at 90 to the said disk or sector, the said pinion being directly or indirectly provided with a two-armed lever which for example at each end is provided with astring in such a way that the ventilator may be opened and closed by a pull in one or the other of these strings or by taking hold of the two-armed lever directly by hand and by turning same in the same way as a thumb screw.
  • a further object of the invention is with reference to the last paragraph to arrange the said two-armed lever in such a way with reference to the pinion orthe shaft that the arms may be detached and mounted in different positions at an angle of 90 to each other in such a way that plates 3, 4, 5 and 6.
  • the plates 3 and 6 are by Y underor upper edge of the ventilator or on one I of the sides of same.
  • Fig. 1 illustrates a longitudinal section through a ventilator which is closed.
  • Fig. '2 illustrates a corresponding section through the same ventilator in partly. open position.
  • FIGs. 3 and 4 illustrate corresponding figures of another embodiment of the invention.
  • FIG. 5 and 6 illustrate a further embodiment of the invention.
  • Fig. 7 illustrates diagrammatically the geometrical construction of the operating mechanism for the plates.
  • Fig. 8 illustrates to a larger scale a detail of the actuating mechanism for the opening and closing of the ventilator.
  • Fig. 9 illustrates this mechanism seen from the side and adapted to be used on a ventilator -mounted in such a way that the actuating mechanism will be placed on the lower side of same.
  • Fig. 10 corresponds to Fig. 9 but illustrates the position of the actuating mechanism when arranged on one of the sides of the ventilator.
  • I represents the frame and 2 a register which possibly may be arranged in front of the ventilator, if desired.
  • the opening of the ventilator between the two sides I of the frame is covered by means of four means of hinges I and 8 hinged to each one of the sides I of the frame.
  • the plates 4 and 5 are by means of hinges 9 and I0 connected to each one of the plates nowadays and 6.
  • these plates are provided with stiff rigidly attached bars or rods II and I2 which extend from the plates normal to these and which may have substantially the same length as the width of the plates.
  • these are by means of hinges I3 and I4 connected to bars I5 and I6 which at the other end are hinged to pivot points I1, I8 on the frame.
  • the length of the bars I5 and I6 may preferably correspond to the width of the plates, and the pivotpoints I1 and I8 may preferably be arranged normal to the plates in closed position and directly outside the hinges 9 and Ill and at the same distance from these as the width of each plate. The accurate position of these hinged points, however, and the dimensioning will be generally explained below with reference to Fig. '7.
  • an actuating mechanism I9 which in the drawings is shown as a sector, is pivotally attached at 20 to the frame and is provided with an arm 2i which projects outside the frame of the ventilator.
  • the sector I8 is provided with a roller or the like 22 which has guidingicontact in a slot or the like 23 on the inside of the plate I.
  • the sector is furthermore provided with a hinge 24 whereto isattached a bar 25 which extends to the other end of the ventilator and which here is hinged to an arm 26 which is pivotally journalled 'at the point 21 on the frame and which is in rigid connection with another arm 28 which at its end has a roller or the like 29 which runs in a slot 30 in the plate 6.
  • Fig. 1- the ventilator is illustrated in its closed position. If the ventilator is to be opened, the handle 2I is moved in the direction of the arrow 3
  • Fig. 2 the ventilator is illustrated in partly open position. From this figure it will be seen how the' diflferent parts will move, if the arm 2I is moved further on towards the left side of the drawings. Then finally the plate 3 will take a position on top of the side of the frame I, while the plate 4 will take a position on top of the plate 3. Simultaneously with the above mentioned movements of the different parts on the left side of the ventilator, these movements will by means of the rod 25 be transferred to the arm system 26, 28, and the plates 6 and 5 with corresponding rods I2 and I6 will take part in and perform the movements in a corresponding way.
  • the ventilator is in the position illustrated in Fig. 2 opened to an extent corresponding to A. If it is desired to close the ventilator, the arm 2
  • FIGs. 3 and 4 another embodiment of the ventilator as above described with reference to Figs; 1 and 2 is shown.
  • the two ventilators correspond to each other, and the same reference numerals will be found to a great extent on Figs. 3 and 4 which have already been used with reference to Figs. 1 and 2.
  • the main difference between the two embodiments lies in that mechanism which is used for operating the ventilator.
  • This comprises an actuating mechanism 35 which in the drawings is illustrated as a circle, turnably attached to the frame at 36 and provided with an arm 31 which projects out side'the frame of the ventilator.
  • the circle plate 35 is provided with hinges 38, 39, to which bars 40, H are attached, which extend relatively to each side and are hinged to arms 42, 43, respectively on the plates 3, 6.
  • Fig. 3 the ventilator is shown in its closed position. If it is desired to open the ventilator, the handle 31 is moved in the direction of the arrow 44, and the rods 40, 4I will'swing the plates 3, 6 about their hinges I and 8 at the same time I as the hinges 9 and III will follow the path of and 5 will place themselves right against the sides of the frame, while the plates 4 and 5 will place themselves over the plates 3 and 6.
  • the arm 31 is moved in the direction opposite to the arrow 44, and the different parts will again take the same position as shown in Fig. 3.
  • the plate 6 is hinged to the frame I by means of a hinge 8 in such a way that the hinges may swing from the closed position shown in Fig. 5 according to the are 46 to an intermediate position as shown in Fig. 6, or further in such a way that the plate '8 will place itself on top of the side of the frame i.
  • the plate 5 is provided with a bar 41 which at the point 48 is hinged to the frame i.
  • the point 48- is arranged diagonally in relation to the hinge 8 in a square, where the plate 6 forms one side and the bar 41 the other side.
  • the roller 49 is arranged, having guiding in a slot 50 in the plate .6.
  • an arm 56 with a sector 55 may be provided, to which sector bars 56 and 51 are attached, said bars being connected to the bars ll and M.
  • the swinging movement of the sector 55 will thus cause the two pairs of plates 6, 5
  • Fig. 7 is illustrated how it is preferred. t go about the problem of deciding the different dimensions of the different parts of which the ventilator is constructed.
  • a vdisk which is To this disk are On the frame of the ventilator there is further mounted a pinion Gil which is in mesh with the teeth 59 and which are journalled on the shaft 6
  • a two-armed lever 62, 53 which is attached to the pinion 60 by means of a thumb screw 64 and which is prevented from turning in relation to the pinion by means of projections 65, 66, 61, 68, which maybe arranged on the pinion or on a part directly or indirectly attached to same.
  • the arms 82, 63 may for instance be provided with holes 63, 10, to which a string 7 I, serving to actuate the arms, may be attached.
  • the ventilator On this shaft there is further arranged If the ventilator is mounted with the actuating mechanism in such a way that this will be positioned at the lower or upper edge of the ventilator, the arms 52, 83 must be attached to the pinion 60 as shown in Fig. 9. If, however, the ventilator is mounted in such a way that the actuating mechanism will be positioned on one of the sides of the ventilator, then it is necessary to reset the arms 62, 63 in such a way that they in spite of this turning of the frame of the ventilator itself, will take 'the position in relation to the horizontal which is shown in Figs. 9 and 10. This is done by loosening the thumb screw 64%, whereafter the arms 62, 63 may be shifted 90, which will be seen from Fig. 10.
