Definitions

  • the present invention relates to a kinematic device for cremone bolt closings, comprising a handle assembly and a moving mechanism for the rods of the cremone bolt, which are connected together by a square cross-section shaft, said device being particularly suitable for closing metal doors and windows that open outward.
  • Handles for windows opening outward are found in the state of the art, which, although based on the cremone bolt mechanism (which guarantees optimal closing, locking the window both above and below onto the window frame), move the cremone bolt rods by means of sliders, which move the cremone bolt rods directly.
  • the handle forms an integral part of this type of device and, consequently, it cannot be used separately in other types of accessory, whatever its aesthetic value may be.
  • Object of the present invention is to provide an improved kinematic device for cremone bolt closings, comprising a handle assembly with a square cross-section shaft and a moving mechanism, particularly suitable for use in door and window frames opening outward, and designed in such a way that the handle assembly and the shaft can be separated from the moving mechanism and used separately if desired.
  • the subject matter of the present invention is a kinematic device for cremone bolt closing devices for door and window frames, comprising a handle assembly, a moving mechanism, connected by a shaft, characterized in that said handle assembly comprises a handle, coupled by a first tubular element, the engaged end being integral therewith, and by means of a boss to a second tubular element arranged in a substantially central position on the upper part of a support case, substantially in the shape of a parallelepipedon, a first bore being formed in a substantially central position on said boss, there being formed in the lower part of said case a first housing of substantially circular form and a pair of grooves arranged in a diametrically opposite position with respect to first said housing and in communication therewith, a positioning ring with a square opening being arranged in said first housing, a plurality of indentations being formed symmetrically around the external edge of said ring, said indentations being arranged so as to cooperate with spherical elements held against said outer edge by the action of spring elements
  • figure 1 shows the kinematic device, which comprises the handle group 1' and the moving mechanism 2, connected by a square cross-section shaft 3.
  • the handle 1 (as can be seen more clearly in figure 2) has engaged at its end a first tubular element 4 (into which the shaft 3 is inserted), which can be connected to the bore 8 (first bore) of a boss 7.
  • a projection 9 is formed, which cooperates with a spring element 6 and a spacing washer 5 to keep the boss 7 against the support case 10.
  • the support case 10 substantially in the shape of a parallelepipedon, has on its upper surface 11, in a substantially central position, a second tubular element 12 and, in a substantially symmetrical position with respect to the second tubular element 12, a pair of bores 13, 13' and a pair of bevels 14, 14' formed on the edge 15.
  • a first housing 17 is formed, of substantially circular shape, and a pair of grooves 18, 18' arranged in a diametrically opposite position with respect to said housing and in communication therewith.
  • a spacing washer 19 is placed, upon which rests in a coaxial relationship a positioning ring 20 with a square cross-section internal opening 21 corresponding to that of the shaft 3.
  • the ring 20 also has a plurality of indentations 23 made symmetrically around the external edge 22 of the ring 20.
  • the indentations 23 cooperate alternately with a pair of spherical elements 24 inserted in the grooves 18 and held in position against the outer edge 21 of the ring 20 by respective spring elements 25. Reciprocal engagement of the spherical elements 24 with the indentations 23 determines and fixes the angular open/closed positions of the handle 1.
  • a second closing plate 26 is provided to close the bottom of the case 10, said second closing plate having a central bore 27 (third bore) and a pair of bores 29, 29' for the passage of fixing elements 28, 28'.
  • the boss 7 in its operative position is pushed by the spring element 6 against the case 10, and engages along its perimeter 33 with the corresponding step 34 formed along the edge 15 of the case 10.
  • the bevels 14, 14' facilitate disengagement of the perimeter 33 of the boss 7 from the step 34, in order to allow rotation around the second tubular element 12 of the boss itself and to enable the operator to access the pair of bores 13, 13' to insert the check pins 30 into the handle assembly (as can be seen more clearly in figure 5).
  • An upsetting, not shown, of the edge of first tubolar element 4 on the ring 20 prevents the handle separating from the structure to which it is coupled.
  • the moving mechanism 2 is contained inside a box-shaped body 35, having substantially the shape of a parallelogram, closed on one side by a first closing plate 36 on which is formed, in a substantially central position, a bore 37 (second bore) for passage of the shaft 3.
  • the shaft 3 activates a sprocket wheel 38, engaging in the square opening 39 (with dimensions substantially the same as those of the shaft 3) of an adaptor 40, in turn permanently engaged in an axial relation with the sprocket wheel 38.
  • the sprocket wheel 38 and the adaptor 40 are housed in a housing 41 (second housing), on the bottom of which a through bore 42 is formed, and their top parts cooperate with a centering bush 43.
  • the teeth 38' of the sprocket wheel 38 engage with a pair of rack elements 44 and 45, moving them symmetrically and longitudinally in opposite directions, each element 44, 45 being integral with a respective guide 46, 47 by means of a respective pair of fixing elements 48, 49 and 48', 49', each guide sliding in a respective straight guide housing 50 and 51.
  • a plurality of bores 52, 52' .... 52n and 53, 53' ... 53n is formed in the rack elements 44 and 45, said bores being formed in a spaced relationship corresponding to the teeth on the sprocket wheel 38, the bore closest to the end of the shaft (respectively 52 and 53) not engaged with the guides being open at the bottom to facilitate assembly.
  • box-shaped body 35 in a substantially symmetrical position with respect to the housing 41 (second housing), two housings 54 and 55 are formed to house the pins 30 fixing the moving mechanism 2 to a frame.
  • Said box-shaped body 35 is also provided with a ledge element made up of two elements 56 and 56' fixed by pins 57, 57'.
  • the first closing plate 36 is fixed to the body 35 of the fixing elements 58 through relative bores 58'.
  • the elements 48 and 49 serve to engage the ends of the rods 59 and 60 of the cremone bolt for movement thereof, by means of common devices which are not specified further.
  • Rotation of the handle 1 between two angular positions offset by 90° one from the other and regulated by the reciprocal engagement of the ring 20 and the spherical elements 24, is transmitted through the shaft 3 to the sprocket wheel 38.
  • the subsequent rotation of the sprocket wheel 38 moves the cremone rack elements 44 and 45 and, consequently, both the guides 46 and 47 and the elements 48 and 49, which govern the movement of the rods 58 and 60 to close or open the window, respectively.
  • the kinematic device according to the present invention differs from those known to the state of the art above all due to the fact that it is a mechanism in which a handle associated with a square cross-section shaft is used for cremone bolt closing mechanisms in outward-opening windows made of metal profiles. Furthermore, the use of a square (sides of the square cross-section of the shaft 3) and a distance between the centers of bores 13 and 13' unified to 7 and 43 mm, respectively, increases versatility, allowing the handle group to be used also in common door and window frames opening inward.
  • the distance between the centers of the bores and the profile acting as a frame has been chosen in such a way that the handle does not interfere with the frame profile itself during opening.
  • Figure 7 shows an axonometric view of a cross-section of a profile in which bores 62 and 63 have been made for passage of the fixing pins, and bore 61 for passage of the square cross-section shaft, and cavity 64 has been made to hold the moving mechanism.
  • Figure 9 shows a cross-section view from above of an application of the kinematic device according to the present invention for a central connection in a two-part window opening outward.
