Definitions

  • the invention relates to a strap winder, operating mechanism for a shutter, roller blind or the like comprising such a reel and a method for adjusting the spring tension of such a reel.
  • the expression strap or the like covers all types of flexible links that may be rolled up and used to operate a roller shutter or blind or an equivalent device.
  • a strap, strap or any another flexible link for operating a shutter or blind rolling and, more generally, for any device comprising an apron capable of being selectively wound on a tree for whether or not to block an opening, such as a window or building door.
  • a strap winder proximity of such an opening such a reel comprising a spring of which a first end is connected directly or indirectly to the strap, while its other end is connected to a fixed point, this spring being enclosed in a generally cylindrical housing arranged inside of a body or covering, as described in EP-A-0 812 795.
  • the box containing the spring is generally fixed on a pin integral with the body or covering, the housing comprising a central sleeve intended to be fitted around the pin cited above.
  • the case also includes a peripheral part, most often called “crown", intended to be secured to one end of the strap and capable of rotate around the sleeve and the pin according to the position of the strap and any tensile force exercised by a user on it. In operation, this type of device is generally satisfactory.
  • the spring of the reel is armed, in this sense that the spring is tensioned by rotating the crown by relative to the sleeve, the crown then being immobilized by relative to the sleeve by means of a removable cooperating cleat with a lever secured to the sleeve.
  • the cleat is removed and the spring exerts on the strap, through the crown, an effort winding.
  • the initial voltage or arming value of the spring is therefore an average value set at the factory.
  • the invention relates to a winder strap of the aforementioned type which comprises controlled means of selective attachment of the housing sleeve in which is arranged the spring and the pin on which this sleeve is mounted, these means being able to immobilize the rotating sleeve around the counter in a first configuration and to allow the rotation of the sleeve around this pawn in a second configuration.
  • the adjustment is greatly facilitated compared to state devices technique because the crown can be held together of the strap while the sleeve is rotated to increase or decrease the spring tension. During the adjustment operations, it is therefore possible for the installer to immediately check the result of this rotation by the grip of the strap which remains integral with the crowned.
  • the invention also relates to an operating mechanism a shutter, roller blind or equivalent, which includes a strap winder as previously described.
  • Such operating mechanism is easier to install and therefore more economical than known devices, while it allows a precise adjustment of the tension of the strap it includes.
  • the reel 1 shown in Figures 1 and 2 is provided for winding a shutter control strap 2 rolling.
  • the winder 1 comprises a housing 3 formed by a sleeve 4 and by a peripheral crown 5 and inside which is disposed a flat spring 6.
  • the housing 3 is provided to be mounted on a piece 7 piece with a casing 8 of the reel which is partially shown.
  • X-X ' the axis of symmetry of pawn 7 which is also a main axis items 3 to 5.
  • the sleeve 4 forms two flanges 40 and 41 inside which penetrate the sides 51 and 52 of the crown 5.
  • a first end 61 of the spring 6 is made integral with a punctured 42 of the sleeve 4 while its second opposite end 62 is made integral with the crown 5 by any appropriate means.
  • the sleeve 4 is immobilized in rotation on pin 7 around the axis XX 'while the crown 5 is able to rotate around of the axis XX ', that is to say of the sleeve 4, as a function of the strap tension 2.
  • a lever 43 radially extends the flange 40 on a small width. This lever is able to cooperate with a cleat 53 mounted on the crown 5 to immobilize in rotation elements 4 and 5 before installing the reel. When the reel is positioned on the pin 7, the cleat 53 is removed, so that crown 5 can rotate around the sleeve 4.
  • a key 10 is arranged between the outer surface of pin 7, which is grooved, and the inner surface of the sleeve 4.
  • the key 10 is mounted on a stirrup 44 radially extending the sleeve 4 in the direction of the axis XX '.
  • This stirrup defines, on each of its sides, two oblong slots 45 and 46 inside which are received two axes 10 a and 10 b integral with the key 10 which is therefore capable of sliding in the direction of the arrow F 1 to Figure 2, that is to say radially with respect to the axis XX '.
  • a spring 11 is interposed between the sleeve 4 and the key 10 and exerts on it a force F 2 directed towards the axis XX ′. This effort tends to press the key 10 against the pin 7.
  • the key 10 is provided with a rib 10 c , the width of which is such that it can penetrate one of the grooves 71 as a function of the position of the sleeve 4 around the pin 7.
  • the key 10 thus constitutes a locking clip ordered from the sleeve 4 relative to the pin 7.
  • the grooves 71 and the rib 10 c can be inclined, which gives a preferential direction to the rotation movement of the sleeve 4 relative to the pin 7.
  • This embodiment has the particular advantage that the key or clip 10 can be pushed back against the force F 2 by an operation consisting in turning the sleeve 4 around the pin 7 in the counterclockwise direction in FIG. 2A .
  • This has the effect of driving the rib 10c from the groove 71 in which it is engaged because the inclined surfaces of this rib and of this groove together form ejection ramps from the rib 10c.
  • a single rotational movement of the sleeve 4, for example in a direction of arming of the spring 6, has the effect both of releasing the clip 10 and of tensioning the spring 6.
  • the reel 101 of this mode of realization is provided for the winding of a strap 102 and includes a housing 103, formed of a sleeve 104 and a crown 105, inside which is disposed a flat spring 106.
  • X-X the main axis of the housing 103, that is to say elements 104 to 106.
  • a pin 107 in the form of a hollow tube is integral with a shell 108 of the reel 101 provided 181 and 182 mounting brackets against a partition and a brake 183 for strap 102.
  • the sleeve 104 is able to be placed around the pin 107 whose external radial surface is generally smooth and whose we denote X-X 'the axis of symmetry.
  • a thicker ring 107a is formed on the outer radial surface of pin 107, at close to hull 108.
  • a spring 111 is arranged inside the pin 107 while an elastic piece of plastic 110 is intended to close off the end of pin 107 when the sleeve 104 is in place on this one.
  • the geometry of the part 110 is more clearly shown in FIG. 4.
  • This part 110 can be considered as a "locking clip" of the housing 103 on the pin 107 because it effectively serves to immobilize the housing 103 on the pin 107.
  • the clip 110 comprises a main surface 112 generally in the form of a disc and in which an opening 113 in the form of a cross is formed. From two radial protrusions 114 of the surface 112 extend, parallel to a main axis X 110 -X ' 110 of the clip 110, lugs 115, two in number by protrusions 114. Each lug 115 is provided with a end 116 in the form of a hook directed opposite the tab 115 carried by the same projection 114. In other words, the hooks 116 are directed towards the outside of the volume 117 defined between two adjacent legs 115.
  • the sleeve 104 is formed by rolling a sheet of metal 204 shown in Figure 8 and includes three tabs 141, 141 'and 142 intended to be curved radially outward from the sleeve 104 in order to immobilize between them the sides of the crown 105.
  • a lever 143 is also provided in the form of a longer length tongue important, this lever being able to cooperate with a cleat formed by the head of a screw inserted in a thread 153 provided in a side 151 of the crown 105.
  • the sleeve 104 also defines two clearances 145 and 146 for receiving the legs 115 of the parts 110.
  • the sleeve 104 further comprises a tongue 147 intended to allow hooking one end 161 of the spring 106, like the punctured 42 of the first embodiment.
  • the sleeve 104 has, over its width in FIG. 8, a groove 104a obtained by striking, this groove being provided to style the rod 107a in the mounted configuration of the device, as shown in Figures 6 and 7.
  • this groove being provided to style the rod 107a in the mounted configuration of the device, as shown in Figures 6 and 7.
  • the sleeve 104 is effectively held in position, by snap-fastening by force, in the axial direction X-X 'of the pin 107.
  • the internal surface 171 of the pin 107 forms two depressions 172 and 173 substantially diametrically opposite and extending over a length 1. These depressions 172 and 173 form receptacles for receiving the tongues 118 of the piece 110, and more specifically from their heads 119.
  • transition surfaces 172 a and 173 have depressions 172 and 173 and of the cylindrical part 174 are rounded and their shape corresponds to the geometry of the heads 119, which facilitates the passage of these heads from the position of FIG. 6 to that of FIG. 7.
  • the heads 119 can rotate freely around the axis XX 'because they are in contact against the surface 174 which is cylindrical. In this position, it is therefore possible to rotate the sleeve 104 around the pin 107, the part 110 being rotated with sleeve 104.
  • the invention has been shown with two examples locking members constituted by the key 10 of the first embodiment and by the clip 110 of the second embodiment of achievement. However, it is not limited to these achievements and covers all ordered means of securing selection of the sleeve and the pin of a reel.
