Description
"Mécanisme de verrouillage d'un store mécanique"."Locking mechanism for a mechanical blind".
Cette invention a pour objet un mécanisme de verrouillage d'un store mécanique dans sa boîte. Il a également pour objet un store mécanique équippé d'un tel mécanisme. This invention relates to a mechanism for locking a mechanical blind in its box. It also relates to a mechanical blind equipped with such a mechanism.
Il existe diverses solutions de mécanisme de verrouillage plus au moins coûteuses, telles que par exemple celle décrite dans la demande de brevet 8704025 dans laquelle des pattes fixées au profilé frontal pénètrent sous la pression de ressorts dans des cavités correspondantes adaptées dans les supports latéraux de la boîte à store, ou encore dans la demande de brevet 8810961 dans laquelle le profilé frontal fermant la boite à store possède un redan coopérant avec un verrou fixé à la boîte, le verrouillage de la fermeture étant assuré automatiquement par l'enroulement du store, et le déverrouillage étant commandé par des tétons fixés sur ce rouleau, qui entraîne le verrou au moment où débute le déroulement du store. There are various more or less expensive locking mechanism solutions, such as for example that described in patent application 8704025 in which lugs fixed to the front profile penetrate under the pressure of springs into corresponding cavities adapted in the lateral supports of the blind box, or in patent application 8810961 in which the front profile closing the blind box has a step cooperating with a latch fixed to the box, the locking of the closure being ensured automatically by the winding of the blind, and the unlocking being controlled by pins fixed on this roller, which drives the lock at the moment when the unwinding of the blind begins.
Dans cette demande de brevet 8810961, le verrou de la boite est monté dans une glissière fixée dans cette boite, l'un des bras de cette glissière se terminant par un corps angulaire correspondant à la pointe angulaire du profilé frontal. In this patent application 8810961, the lock of the box is mounted in a slide fixed in this box, one of the arms of this slide ending in an angular body corresponding to the angular tip of the front profile.
Néanmoins l'action répétée du verrouillage et déverrouillage peut endommager cette glissière par la pointe angulaire du redan du profilé frontal. However, the repeated action of locking and unlocking can damage this slide by the angular tip of the step of the front profile.
Le but du mécanisme de verrouillage d'un store mécanique suivant l'invention est de remédier à cet inconvénient en suprimant cette glissière. The purpose of the locking mechanism of a mechanical blind according to the invention is to remedy this drawback by removing this slide.
Le mécanisme de verrouillage d'un store mécanique suivant l'invention est du type de la demande de brevet 8810961, caractérisé en ce que le verrou est constitué par un levier articulé sur un axe fixé à la boite du store, l'un des bras de ce levier étant terminé par une pointe angulaire correspondante à la pointe angulaire du redan du profilé frontal et s'accrochant à celle-ci au moment où le redan du profilé frontal pénètre dans la boite du redan tandis qu' à l'autre bras du levier est fixé un ressort qui ramène le levier dans sa position normale, une fois l'accrochage réalisé entre les deux pointes angulaires. The locking mechanism of a mechanical blind according to the invention is of the type of patent application 8810961, characterized in that the lock is constituted by a lever articulated on an axis fixed to the blind box, one of the arms of this lever being terminated by an angular point corresponding to the angular point of the step of the front profile and clinging to it at the moment when the step of the front profile enters the box of the step while at the other arm of the lever is attached a spring which returns the lever to its normal position, once the attachment is made between the two angular points.
D'autre caractéristiques et avantages du mécanisme de verrouillage d'un store mécanique suivant l'invention ressortiront de la description de deux cas spécifiques illustrés au moyen des figures jointes sans pour autant limiter l'objet de l'invention aux modes d'exécution décrits. Other characteristics and advantages of the locking mechanism of a mechanical blind according to the invention will emerge from the description of two specific cases illustrated by means of the attached figures without limiting the object of the invention to the embodiments described. .
La figure 1 représente une coupe d'un store mécanique suivant l'invention dans la position du store en cours d'enroulement avant verrouillage. Figure 1 shows a section of a mechanical blind according to the invention in the position of the blind during winding before locking.
La figure 2 est une vue perspective des éléments d'un autre store mécanique suivant l'invention. Figure 2 is a perspective view of the elements of another mechanical blind according to the invention.
Un store mécanique, dont la coupe est représentée à la figure 1, comprend une boite (1) à store, un rouleau (2) sur lequel est enroulé le store (3) proprement dit, toile ou autre, qui se termine par un profilé frontal (4), qui lorsque le store est complètement enroulé est parfaitement adapté à la boite (1) qui est fermée par ce profilé (4). A mechanical blind, the section of which is shown in FIG. 1, comprises a blind box (1), a roller (2) on which the blind (3) itself, canvas or other, is wound, which ends in a profile. front (4), which when the blind is fully rolled up is perfectly suited to the box (1) which is closed by this profile (4).
Le profilé frontal (4) comprend entr'autres au fond de la cornière (5) un redan (6) composé d'une pointe angulaire (7) et d'une découpe (8) de préférence rectangulaire. The front profile (4) comprises, among others, at the bottom of the angle iron (5) a step (6) composed of an angular point (7) and a cutout (8), preferably rectangular.
D'autre part dans la boîte (1) est fixée à l'une de ces faces latérales un axe (9) sur lequel est articulé un levier (10) comprenant à l'extrémité d'un bras (13) une pointe angulaire (11) correspondante et inversée à la pointe angulaire (7) du redan (6) du profilé frontal (4) de manière à ce que cette pointe angulaire (7) du redan (6) excerce une pression sur la pointe angulaire (11) du bras (13) du levier (10) au moment ou le redan (6) pénètre dans la boite à store (1) sous l'effet de l'enroulement du store (3) autour du rouleau (2).Par cette pression le levier (10) bascule autour de l'axe (9), en tendant le ressort (12) fixé entre l'autre bras (14) du levier (10) et la boite à store (1), de manière à ramener le levier (10) dans sa position initiale autour de l'axe (9) assurant ainsi le verrouillage de la pointe angulaire (7) du redan (6) du profilé frontal (4) avec la pointe angulaire (11) au bras (13) du levier (10). Dans le mécanisme de verrouillage, dont la coupe est représentée à la figure 1, le levier (10) a une forme en L, dont les deux bras (13) et (14) se rejoignent à l'axe (9) d'articulation. On the other hand, in the box (1) is fixed to one of these lateral faces an axis (9) on which is articulated a lever (10) comprising at the end of an arm (13) an angular point ( 11) corresponding and inverted to the angular tip (7) of the step (6) of the front profile (4) so that this angular tip (7) of the step (6) exerts pressure on the angular tip (11) of the arm (13) of the lever (10) when the step (6) enters the blind box (1) under the effect of the winding of the blind (3) around the roller (2). lever (10) swings around the axis (9), stretching the spring (12) fixed between the other arm (14) of the lever (10) and the blind box (1), so as to bring the lever back (10) in its initial position around the axis (9) thus ensuring the locking of the angular tip (7) of the step (6) of the front profile (4) with the angular tip (11) to the arm (13) of the lever (10). In the locking mechanism, the section of which is shown in FIG. 1, the lever (10) has an L-shape, the two arms (13) and (14) of which meet at the axis (9) of articulation .
Le levier (10) est maintenu d'une part par un ressort (12) de traction reliant le bras (14) à la boîte à store (1) et d'autre part par un arrêt (15) fixé à la paroi supérieure de la boite à store (1) sur lequel vient buter l'extrémité du bras (14) du levier (10).The lever (10) is held on the one hand by a tension spring (12) connecting the arm (14) to the blind box (1) and on the other hand by a stop (15) fixed to the upper wall of the blind box (1) on which abuts the end of the arm (14) of the lever (10).
Lors du déroulement du store (3) un téton (16) fixé à l'extrémité du rouleau (2), sous l'action d'une manivelle ou d'un moteur, vient frapper le bras (14) du levier (10) en obligeant celui-ci de basculer autour de l'articulation (9), déverrouillant automatiquement les deux pointes angulaires respectivement la pointe angulaire (11) du bras (13) du levier (10) et la pointe angulaire (7) du redan (8) du profilé frontal (4) qui peut alors descendre suivant l'opération habituelle du déroulement d'un store mécanique. During the unwinding of the blind (3) a stud (16) fixed to the end of the roller (2), under the action of a crank or a motor, strikes the arm (14) of the lever (10) by forcing it to switch around the articulation (9), automatically unlocking the two angular points respectively the angular point (11) of the arm (13) of the lever (10) and the angular point (7) of the step (8) ) of the front profile (4) which can then descend according to the usual operation of the unwinding of a mechanical blind.
Dans une autre forme d'exécution du store mécanique suivant l'invention tel que représenté à la figure 2, le profilé frontal (4) a une longueur inférieure à celle de la boite (1) à store et comprend au moins une paroi latérale (17) munie à l'extérieur d'un coin dont la pointe (7') au cours de l'enroulement du store (3) vient s'appuyer sur la pointe correspondante (11) du bras (13) du levier (10) articulé autour de l'axe (9) fixé à la paroi latérale (18) de la boite (1) à store de manière à faire basculer ce levier (10) jusqu'au moment où la pointe (11) du bras (13) du levier (10) peut reprendre sa position normale derrière l'arret (6') du coin fixé à la paroi latérale du ressort (12) de traction reliant le bras (14) du levier (10) à la paroi latérale (18) de la boite (1) à store. In another embodiment of the mechanical blind according to the invention as shown in FIG. 2, the front profile (4) has a length less than that of the blind box (1) and comprises at least one side wall ( 17) provided on the outside with a corner, the point (7 ') of which during the winding of the blind (3) comes to bear on the corresponding point (11) of the arm (13) of the lever (10) articulated around the axis (9) fixed to the side wall (18) of the blind box (1) so as to tilt this lever (10) until the point (11) of the arm (13) lever (10) can return to its normal position behind the stop (6 ') of the corner fixed to the side wall of the traction spring (12) connecting the arm (14) of the lever (10) to the side wall (18) from the blind box (1).
Le bras (13) du levier (10) comprend en outre un bouton (19) de forme cylindrique venant s'appuyer sous l'action du ressort (12) de traction sur la paroi transversale du rouleau (2) comportant un chemin de roulement profilé (16'). Au cours du roulement du store (3) autour du rouleau (2), le chemin de roulement profilé (16') pousse sur le bouton (19) du bras (13) du levier (10) à l'encontre de l'effort de traction du ressort (12), en déverrouillant les pointes (7') et (11) respectivement du profilé frontal (4), et du levier (10) permettant ainsi de continuer le déroulement du store (3) suivant l'action habituelle. Après le passage du chemin de roulement profilé (16'), le levier (10) reprend sa position normale. The arm (13) of the lever (10) further comprises a button (19) of cylindrical shape coming to bear under the action of the spring (12) of traction on the transverse wall of the roller (2) comprising a raceway profile (16 '). During the rolling of the blind (3) around the roller (2), the profiled raceway (16 ') pushes on the button (19) of the arm (13) of the lever (10) against the force tension of the spring (12), by unlocking the points (7 ') and (11) respectively of the front profile (4), and of the lever (10) thus allowing the unwinding of the blind (3) to continue following the usual action . After the passage of the profiled raceway (16 '), the lever (10) returns to its normal position.
De fait une fois par tour du rouleau (2), le levier (10) oscille autour de son axe (9) sous l'action respective du chemin de roulement (16') et du ressort (12). Seul le dernier tour lors de l'enroulement le levier (10) sous l'action de la pointe (7') du profilé frontal assure le verrouillage du profilé frontal (4) dans la boîte (1) à storen, tandis que le déverrouillage est assuré au premier tour de déroulement par l'action du chemin de roulement (16')
Le mécanisme de verrouillage suivant l'invention n'est pas limité à ceux décrits. D'autres variantes peuvent être exécutées par exemple en variant la forme du levier (10) - l'endroit de l'articulation (9) - l'application du ressort (12) - ressort en traction ou en compression sans pour autant sortir du domaine de l'invention. In fact once per turn of the roller (2), the lever (10) oscillates around its axis (9) under the respective action of the raceway (16 ') and the spring (12). Only the last turn when winding the lever (10) under the action of the tip (7 ') of the front profile ensures the locking of the front profile (4) in the box (1) to storen, while the unlocking is ensured at the first turn of the unwinding by the action of the track (16 ')
The locking mechanism according to the invention is not limited to those described. Other variants can be executed for example by varying the shape of the lever (10) - the location of the articulation (9) - the application of the spring (12) - spring in tension or in compression without leaving the field of the invention.
