- the pinion 60 continues to roll on the rack 30, which by reaction begins to rise ( Fig. 4 ) and to move the pins 88, 92 upwards. Meanwhile the slots 98 on the panels 10, 12 have moved closer to the pins 92 so that the pins 92 get in the empty space of the slot (see schematic position P1 of a hatched pin 92 in Fig. 9 ).
- the last rotation amount of the pinion 70 concludes the descent of the panels 10, 12 ( Fig. 1 ), and the pins 92 move from the empty space of the slot 98 beyond the edges 99 inside the guide or groove 97, which in this phase is practically aligned with the rack 30. Now the pins 92 are blocked, through interposing parts, by the walls of the guide 97, and the retrograde angular movement of the panel is then prevented (see schematic position P2 of the same pin hatched 92 in fig. 9 ).
- the motor 64 is activated in opposite direction, and the shaft 62 rotates dragging the pinion 60 in the opposite direction.
- the rack 30 is now free to translate ( Fig. 4 ), and gets lowered by the pinion 60 which, consequently, moves forward slightly.
- the pins 92 and the slots 98 follow equal and opposite trajectories as the previous ones, so that the pins 92 first come out from the guide 97 and then from the slots 98, thereby freeing the panels 10, 12.
- the rack 30 reaches the bottom of the upright 14 and stops there, the carriage 36 begins to climb the rack 30 until it moves away from, and no longer presses on, the lever 70, which pushed by the spring returns its end 78 inside the undercut 80. Now the rack 30 is locked and the carriage 30 reaches the upper end-position ( fig. 2 ).

Abstract
Description
- The invention generally relates to a displacement system for two panels, in particular for building shading panels, an application chosen in the following as an example. The displacement system can be exploited to move in general two generic panels or concealment elements bellow-hinged to each other like doors or sectional doors.
- To reduce the energy consumption due to heating and cooling, in constructions external shading systems are used, as in
DE102009014579 , exploiting two hinged panels that can pack as a bellow on each other to uncover a window. When the panels are coplanar (obscured window), these structures have not only the problem that to pack them and lift them one must avoid their stucking using expensive and bulky auxiliary mechanisms (with the function to move outside the panels and brake their alignment), but also the hinge of the panels is not blocked. Therefore, a pressure on the central hinge is enough to make the panels swing, with obvious security and stability problems. Finally, the lifting mechanisms for the panels generally consist of mechanisms being either complicated or difficult to adapt to different models or sizes of panels. - E.g. devices are known which move two liftable panels in front of an opening. They use a rack mounted to the sides of the opening and a pinion driven by an electric motor set on board the bottom panel. The motor runs on the rack in order to vertically lift the panels. This system, in particular, is quite primitive. To endow it with sophisticated or additional controls on the dynamics of the panels, it is necessary to use sensors or switches, long wiring and a management control unit. It would be desirable to assist the electronic control unit with a mechanical feedback indicative of the dynamics of the panels, thereby saving expensive and complicated electronic sensors.
- The main object of the invention is to improve the functionality of a known displacement system for the above panels.
- Another object is to solve the problem of moving said panels in a simple and inexpensive way. Another object is to solve the problem of moving the above-mentioned panels with a simple to build and reliable device, and with a method for moving (e.g. only) two panels which is simple to implement and reliable.
- An aspect of the invention includes a device, capable of implementing the method, destined to move (e.g. only) two panels hinged to each other on an edge thereof and mounted to vertically folding book-like one on the other in front of an opening to be obscured, comprising:
- a rack mounted to the sides of the opening;
- an electric motor located on the bottom panel;
- a rotatable pinion driven by the motor and engageable on the rack to translate on the rack and thereby vertically lifting the bottom panel;
- In the prior art the rack is fixed, immovable on the side uprights of the opening. By making the rack movable instead, it, as a reaction to the momentum imparted to it by the pinion, can instead move as a function e.g. of the position of the panels and/or of the force imparted by the pinion. The stroke of the rack can then indicate a status variable of the system, easily exploitable for the control of the panels (e.g. by coupling a microswitch to the rack to be read by the control unit) or other functions. The rack can move e.g. either by reaction to the momentum of the pinion and/or because of the weight of the panels. This is useful e.g. within the peripheral monitoring of an anti-theft system and/or as position or speed detection system for the panels, e.g. as a control included in an end-of-travel regulation.
- According to a preferred embodiment, the device comprises a (first) locking and unlocking mechanism or device for (e.g. temporarily) locking and unlocking of the rack with respect to the sides of the opening to allow or prevent the movement of the rack in some conditions. In this way the rack can both remain integral with the uprights of the opening, acting e.g. as a fixed guide for the pinion and enabling a stable translation for it, and move to perform other functions.
- According to a preferred embodiment, the device comprises an element which is integral with a panel and destined to trigger the mechanism for locking and unlocking. In this way one can synchronize the condition of motion allowed or denied to the rack with the dynamics of a panel (e.g. position and/or speed).
- Preferably, said integral element is mounted on the bottom panel to activate the locking and unlocking mechanism or device in correspondence of the closing end-of-travel limit of the panels.
- Preferably, said integral element comprises or consists of a carriage on which the pinion is rotatably mounted.
- According to a preferred embodiment, the mechanism for locking and unlocking comprises or consists of a lever movable between two positions: a first position in which by interference it blocks the displacement of the rack and a second position in which it leaves the rack free to translate. The lever may be pivotally mounted and/or linearly translatable, and e.g. mounted on a vertical upright.
- According to a preferred embodiment, the lever is mounted to be moved directly by the pinion or by the carriage, so as to minimize the components and ensure a safe and repeatable activation of the first mechanism or device.
- Preferably, the first mechanism or device comprises an elastic element destined to generate an elastic force to trigger the mechanism or device itself. In particular, the elastic element may be mounted for pushing the movable lever towards one of said two positions.
- Preferably the rack is mounted to activate, by its movement, a second device or mechanism for locking and unlocking a panel with respect to the sides of the opening. The advantage is to exploit the displacement of the rack to lock a panel in the closed position to an upright.
- Preferably, the second mechanism or device comprises one or more pins integral with the rack mounted to protrude from the uprights. The pins can then translate along with the rack and, according to their position, block a panel or not.
- Preferably, a panel comprises grooves or slots, e.g. at an edge, in which one of said pins can enter during the closing movement of the panel itself.
- Preferably, the rack is mounted to activate, by its movement, a third device or mechanism destined to generate a force on a panel, said force being adapted to tilt it relative to the vertical.
- Preferably, the third mechanism or device comprises one or more pins integral with the rack mounted to protrude from the uprights. The pins can then translate together with the rack and, according to their position, slide on one or more inclined planes present on the side of a panel. The cooperation between a pin and an inclined plane creates a cam mechanism.
- Another aspect of the invention also includes a displacement system comprising:
- (i) the device (destined to move the panels) as defined above or described below, and
- (ii) the panels to be displaced.
- Another aspect of the invention includes a method for moving and/or locking (e.g. only) two panels hinged one to the other on an edge thereof and mounted to vertically fold book-like one on the other in front of an opening to be obscured, the panels being comprised in a drive system of the panels which comprises
- a rack mounted to the sides of the opening;
- an electric motor on the bottom panel;
- a rotatable pinion driven by the motor and engageable on the rack to move on the rack and thereby vertically lifting the bottom panel.
- The method comprises the step of linearly moving the rack along its longitudinal axis.
- Optional steps of the method are linearly moving the rack along its longitudinal axis to activate, e.g. by displacement, one or more locking members for a or each panel; and/or to activate, e.g. by displacement, one or more pushing members on a or each panel.
- Positional terms such as e.g. lower or higher or vertical refer to the orientation that the system or the device have normally in use.
- The following description regards a preferred embodiment of the system and will highlight further advantages, by reference to the accompanying drawings in which:
-
Fig. 1 shows a side view of a displacement system for shading panels of a window with the panels in closed position; -
Fig. 2 shows a side view of the system ofFig. 1 with the panels in open position; -

Figs. 1-3 show a displacement system MC for twopanels hinge 18 with horizontal axis X2 along a common edge. Thepanels panels - The
top panel 10 is oscillating in a known manner by means of pins about an axis X1 passing a bit below the upper horizontal margin SP of the opening. - Inside the

rack 30 there are mounted protrusions or protrudingpins 88, 92 (Fig. 1 and 2 ) that protrude from the surface of the upright 14 by means of suitable grooves or pass-throughslots 58 present in the upright 14 itself. Therefore, at some points on the upright 14 thepins rack 30. - The

The groove orinclined plane 86 indeed constitute for the pin 88 a track, which has an entry for thepin 88 on the side edge of thepanel 10, that is, the edge facing down when thepanel 10 is raised. In the proposed example the groove orinclined plane 86 is a simple guide which develops along the thickness (or side) of thepanel 10 with oblique direction with respect to the planes of its major surfaces. - With the
panels Fig. 2 . - The
rack 30 is maximally displaced downwards (in abutment against the bottom of an upright 14) and thelever 70 engages the undercut 80. - To lower the
panels motor 64 is activated, and theshaft 62 rotates dragging thepinion 60, which descends along therack 30 divaricating thepanels - When the
panels carriage 36 reaches the proximity of the lever 70 (Fig. 6 ), so that awheel 22 or the pinion is able to touch thelever 70 causing it to lower. - Then the
lever 70 begins to move away from therack 30, until itsend 78 comes out of the undercut 80 (Fig. 5 ), and accordingly therack 30 is now free to move. - The
pinion 60 continues to roll on therack 30, which by reaction begins to rise (Fig. 4 ) and to move thepins slots 98 on thepanels pins 92 so that thepins 92 get in the empty space of the slot (see schematic position P1 of a hatchedpin 92 inFig. 9 ). The last rotation amount of thepinion 70 concludes the descent of thepanels 10, 12 (Fig. 1 ), and thepins 92 move from the empty space of theslot 98 beyond theedges 99 inside the guide orgroove 97, which in this phase is practically aligned with therack 30. Now thepins 92 are blocked, through interposing parts, by the walls of theguide 97, and the retrograde angular movement of the panel is then prevented (see schematic position P2 of the same pin hatched 92 infig. 9 ). - In the opening phase the operations take place in reverse order.
- To lift up the
panels motor 64 is activated in opposite direction, and theshaft 62 rotates dragging thepinion 60 in the opposite direction. Therack 30 is now free to translate (Fig. 4 ), and gets lowered by thepinion 60 which, consequently, moves forward slightly. Thepins 92 and theslots 98 follow equal and opposite trajectories as the previous ones, so that thepins 92 first come out from theguide 97 and then from theslots 98, thereby freeing thepanels - Together with the
rack 30 also thepin 88 descends, which meets theinclined plane 86 and slides over it generating a force to move thepanel 10 away from the opening (clockwise rotation inFig. 2 ). That is, the cooperation of thepin 88 and theinclined plane 86 generate a momentum able to rotate thepanel 10 in the direction that brings it upwards. So the deadlock on the vertical of thepanels - The
rack 30 reaches the bottom of theupright 14 and stops there, thecarriage 36 begins to climb therack 30 until it moves away from, and no longer presses on, thelever 70, which pushed by the spring returns itsend 78 inside the undercut 80. Now therack 30 is locked and thecarriage 30 reaches the upper end-position (fig. 2 ).
Claims (10)
- Device (MC) destined to move two panels (10, 12) hinged to each other on an edge thereof and mounted to vertically folding book-like one on the other in front of an opening to be obscured, comprising:- a rack (30) mounted to the sides of the opening;- an electric motor (64) located on the bottom panel (12);- a rotatable pinion (60) driven by the motor and engageable on the rack to translate on the rack and thereby vertically lifting the bottom panel;characterized in that
the rack is mounted to be able to move linearly along its longitudinal axis. - Device according to claim 1, comprising a mechanism for locking and unlocking (70) of the rack with respect to the sides of the opening, the locking and unlocking device being destined to prevent or allow the movement of the rack.
- Device according to claim 2, comprising an element (36) which is integral with a panel and destined to trigger the mechanism for locking and unlocking.
- Device according to claim 3, wherein said integral element comprises or consists of a carriage (36) on which the pinion is rotatably mounted.
- Device according to claim 2 or 3 or 4, wherein the mechanism for locking and unlocking comprises or consists of a lever (70) movable between two positions: a first position in which by interference it blocks the displacement of the rack and a second position in which it leaves the rack free to translate.
- Device according to claim 5, wherein the lever is mounted to be moved directly by the pinion or by the carriage.
- Device according to claim 5 or 6, comprising an elastic element destined to generate an elastic force to trigger the mechanism for locking and unlocking.
- Device according to any one of the preceding claims, wherein the rack is mounted to activate, by its movement, a device for locking and unlocking (92) a panel with respect to the sides of the opening.
- Device according to any one of the preceding claims, wherein the rack is mounted to activate, by its movement, a device (88) destined to generate a force on a panel to tilt it relative to the vertical.
- Method for moving and/or locking two panels (10, 12) hinged one to the other on an edge thereof and mounted to vertically fold book-like one on the other in front of an opening to be obscured, the panels being comprised in a drive system (MC) of the panels which comprises- a rack (30) mounted to the sides of the opening;- an electric motor (34) on the bottom panel (12);- a rotatable pinion (60) driven by the motor and engageable on the rack to move on the rack and thereby vertically lifting the bottom panel;the method comprising the step of linearly moving the rack along its longitudinal axis.
