Definitions
- the invention relates to a deployable device comprising different boards, including a stepladder.
- the ladder assembly is configured to pull out of the drawer and rise to an unfolded position to form a two-step ladder when the drawer is open. It is known to have a deployment of the stepladder assembly activated by pressure on a first control member placed at the front of the drawer. It is known that the drawer opens and slides automatically, by a translational guiding mechanism, and that means for moving in translation movement out of the drawer all step ladder; this means is either a spring or a motor. Once the drawer is open, a second control member activates the rotation of a spring or a motor that will vertically deploy the ladder.
- this solution has the disadvantage that the two steps are superimposed when they are stored in the drawer, and that during their deployment, the two steps remain partially superimposed.
- This has the disadvantage of reducing the board useful for placing the user's feet on the board forming the step because of the interference of the upper step, making it insecure the rise of this stool, and to limit the number of steps. Indeed, the number of steps depends on the ability to stack them in the drawer, which must go under a piece of furniture. The low storage height under the furniture, commonly less than 10 centimeters or even less than 7 centimeters can stack only few steps.
- This solution is not suitable for the realization of storage spaces such as drawers compartments superimposed instead of steps.
- the drawers compartments stacked in the stowed position will have a low height because of their stacking, thus limiting their use as a drawer, and does not allow access to the rear of the storage or to make compartments forming satisfactory drawers.
- This solution is not suitable for the realization of storage spaces such as shelves. Indeed, just like the steps, the shelves remain partially superimposed. This has the disadvantage of reducing the board useful for storing objects due to the interference of the upper shelves encroaching on the shelves directly below.
- the known solutions do not make it possible to respond satisfactorily to these different applications.
- the invention relates to a deployable device from a retracted position to a deployed position, comprising at least a first board and a second board, the first and the second board extending in the deployed position according to a first plane and a plane respectively horizontal plane and offset between them, the device comprising a frame provided to be horizontal and a deployment mechanism comprising two subassemblies on either side of the boards for guiding the boards between the retracted position and the deployed position, and vice versa, the first board being shifted towards the rear of the device relative to the second board in a horizontal main direction when the device is in the extended position, characterized in that when the device is in the retracted position, the first board is shifted towards the front of the positive and the second board is shifted rearward, the two boards being located substantially at the same level and parallel to the first and second plane, the frame being detached, fixed, or connected to an environment by at least one telescopic arm deployment horizontal.
- the term "at the same level” means a position at a nearby altitude, measured on a vertical axis, that is to say perpendicular to the first and second planes.
- the device in retracted position is compact and can store in a small space, especially of low height. It can be fully mobile or attached to an environment telescopically, for example as a drawer.
- the offset of the boards in the retracted position allows to place them without being superimposed, and thus optimize the overall height.
- the inversion of their placement between the deployed position and the retracted position allows their trajectory remains substantially in the size of the frame, and thus facilitates the deployment without interfering with surrounding objects.
- the boards may be steps so that the device forms a step ladder. They can also be bins so that the device is a storage and presentation facility.
- the frame can be fixed on the upper face of a piece of furniture, fixed or mobile, or on the lower face for deployment downwards. It can also be simply free to be placed on the ground.
- each subassembly comprises a main bar pivotally mounted on the frame towards the rear, a first support bar for supporting the first board and pivotally mounted at an upper end of the main bar, a first connecting rod pivotally mounted also at the high end of the main bar, and a second connecting rod in alignment with the first link in the deployed position and pivotally mounted on the frame forward.
- the main bar forms a triangle with the frame and with the first and the second link when they are aligned in the deployed position, whereas when the first and the second link are folded on themselves, in the retracted position, the main bar is folded along the frame, horizontally. In this way, it is easy to deploy the first board by pivoting guidance.
- the pivot axis of the first connecting link B on the second connecting link is shifted towards the axis of pivoting of the main bar on the frame relative to the segment formed by the axes. pivoting of the first connecting billet on the main bar and the second connecting billet on the chassis.
- the subassembly further comprises a second support bar for supporting the second board, parallel to the first support bar and pivotally mounted on the first connecting link on the same axis as the second connecting link, and a third connecting link parallel to the first connecting link and pivotally connected to the first and second support bars, so that the pivot axes of the first and third connecting links are distributed at the vertices. of a first parallelogram. This ensures the parallelism between the support bars, and therefore between the boards, and the synchronization of their deployment.
- the subassembly further comprises a fourth connecting link parallel to the second connecting link and pivotally connected to the second support bar and the frame so that the pivot axes of the second and of the fourth connecting link are distributed at the vertices of a second parallelogram. This ensures the parallelism of the support bars, and therefore boards, to the frame.
- the subassembly further comprises a holding bar pivotally mounted on the second support bar at one end and slidably and pivotally mounted at the second end on the frame in the horizontal main direction so as to form a locking leg of the second support bar in the extended position being close to the vertical.
- the holding bar provides a significant stiffening of the deployment mechanism, offering a recovery of vertical loads related to the weight taken up by the boards.
- the support bar ensures the deployed position against the forces exerted on the surfaces.
- the holding bar is connected to a first gas spring connected to the frame and tending to move the sliding end of the holding bar towards the locking leg position.
- the first gas spring contributes to the deployment of the device, particularly during the phase towards reaching the deployed position.
- the support bar contributes to the alignment of the third and fourth connecting rod, and therefore the first and second link.
- the holding bar comprises a pivot guided in a slide of the frame, the slide having a notch in which the pivot is housed in the extended position by a movement of the holding bar downwards, so as to prevent slipping the pivot in the slide when a load is on one or other of the boards.
- the holding bar can no longer rotate and thus ensures blocking position of the subassembly in the deployed position.
- the first gas spring comprises locking means for locking a rod of the first gas spring in the extended position and preventing the pivot sliding in the slide in the deployed position, and tension means tending to push the rod of hold up.
- the tensioning means are for example a mechanical spring acting on the first gas spring to rotate it, or on the pivot accompanying its translation.
- the locking of the first spring ensures that the pivot is inserted into the notch when a load is on the boards, by a slight downward movement of the holding bar against the tensioning means.
- the locking means can be controlled remotely. When released, the load on the boards tends to compress the gas spring and retract the rod, so that the pivot slides in the slideway without engaging the notch and allows the return of the device to the position retracted. This movement is accompanied by the tensioning means which oppose the engagement of the pivot in the notch.
- the elements of a subset of the deployment mechanism are arranged in a transverse direction, that is to say horizontal and perpendicular to the main direction, in the following manner, from the outermost to the innermost:
- the second link rod pivotally mounted outside a vertical wing of the frame
- the fourth connecting link pivotally mounted inside the vertical wing of the frame.
- This arrangement ensures that the elements of the subassembly can be stored next to each other in the closed position, so as to limit as much as possible the overall height in this position.
- the holding bar is disposed after the fourth connecting rod.
- each subassembly comprises a second gas spring connecting the frame and the main bar to tend to place the device in the deployed position.
- a type of spring comprising a tubular body and a sliding rod in the tubular body forming a cylinder, tends to cause the rod to come out under the effect of a compressed gas. It also provides damping of the movement.
- the shaft and the body are pivotally or rotatably mounted respectively on the frame and on the main bar.
- the second gas spring connects the main bar near the upper end of the main bar.
- the main bar has a first bead extending the main bar beyond the pivot axis on the frame of so that the first bead protrudes under the frame when the device is in the extended position to bear on the ground, and retracts in the retracted position.
- the deployment of the device causes the heel to emerge under the frame so that the device is kept on the ground without rolling and thus acquires a stable position.
- the second link comprises a second bead extending the second link beyond the axis of pivoting on the frame so that the second bead protrudes under the frame when the device is in the deployed position to take support on the ground, and retracts in retracted position.
- the same function as above can also be performed in this way, in addition or alone.
- each subassembly comprises a locking mechanism arranged to bind together in the deployed position and in the retracted position the first and the second connecting rod or the third and fourth connecting rod.
- This locking mechanism replaces the function of the holding bar by joining the first and the second link so that this assembly forms with the frame and the main bar a rigid triangle, or, in the case of the assembly formed by the third and the fourth connecting link stiffens the first and second parallelograms.
- the locking mechanism comprises a body fixed on one of the bells between the first and the second connecting rod, the other connecting rod comprising an arm extending said link beyond the pivot axis between the two biel Furthermore, the locking mechanism further comprises a bolt slidably mounted in the body resiliently and arranged to cooperate with a first strike carried by the arm and a second strike carried by the other link opposite the first. keeper with respect to said pivot axis.
- the device comprises a stop mechanism arranged to bind together the second or the first board and the frame in the retracted position.
- the device deploys only on the release of the stop mechanism and is kept in the retracted position otherwise, even when the device is moved.
- the locking mechanism is remotely controlled by a maneuvering member.
- the operating device may be a pedal or a pivoting or pulling handle. It can be monostable or bistable, that is to say with a position or two stable positions.
- the chassis comprises steerable rollers and behind the stop means extending substantially vertically and transversely, the stop means being adapted to be engaged with a guide wing attached to an environment for retaining in the main direction and transversely guide the device. It is thus possible to move the device on its wheels to the position in which the stop means are in contact with the guide wing, and then move the device transversely along said wing.
- This configuration is particularly interesting when the device is stored under a piece of furniture belonging to a linear furniture from which it is extracted and then dragged along the linear to the desired furniture to place it at the place where we want to use the device.
- the stop means are retractable. It is thus possible to completely release the device.
- the chassis comprises wheels on which the device can be moved while rolling, the casters being escamo tables so that the device bears on the ground on fixed pads when a weight is supported on the device.
- the device can be moved easily, especially if the casters are steerable, when not loaded, and rest on the pads, for example adherents, when a person rides on the device, which stabilizes completely the device in charge.
