Definitions
- the present invention relates to an improvement in leg and foot support structure applied to recliners.
- This conventional constructivity enables a first starting position where the seat and backrest are in the normal sitting position and the leg and footrest retracted. In a second position, the seat and the backrest move forward and tilt, and the front of the seat pivots upward, forming the footrest. In some cases, there is a third position, where the backrest tilts more, to seek a more relaxed position.
- Another object of the present invention is to provide an improvement in the leg and foot support structure applied to reclining armchairs that allows for a minimum clearance between the floor and the seat base of the armchair or sofa to offer great freedom. of creation for the designer.
- the goal is to enable the creation of modern, lightweight designs that do not reveal the multiple functions of the furniture when it is in the closed position.
- Another object of the present invention is to provide an improvement in the leg and foot support structure applied to reclining seats that remain tucked under the seat when inoperative and which folds forward when in a position of use. obtaining a larger extension than usually achieved, so as to cater for people of greater stature.
- Another object of the present invention is to provide an improvement in the leg and foot support structure applied to reclining chairs that has a simple constructivity to the parts that make up the armchair support and drive system and allows the use of different types of armrests. armchair support base.
- Another object of the present invention is to provide an improvement in support structure for leg and foot applied reclining armchairs that is structurally self-supporting, without the need for complementary structures, and which has a reduced number of moving parts, thereby reducing the total weight of the seat. set.
- Another object of the present invention is to provide an improvement in leg and footrest structure applied to reclining armchairs that allows the footrest to be positioned at different and various heights.
- leg and foot support structure applied to reclining armchairs of the type comprised of a rigid quadrangular basic structure formed by transverse and extremely interconnected side members. anterior and posterior, said rigid and quadrangular basic structure being horizontally raised and distant from the ground by means of support bases that determine an apparent free space between the ground and the horizontal base of the armchair; whereas in the front half and internally to this rigid base structure is mounted a hinged quadrangular frame provided previously with a second inner sliding frame defining a retractable footrest assembly; all moving parts that make up this structure are driven by specific transmission assemblies formed by articulated arms connected and controlled simultaneously by a drive unit.
- the improvement lies in the fact that it provides a system of articulated arms coupled to a sliding structure, dimensioned in such a way as to allow the reduction of the seat height without prejudice to the final length of the support when extended; provide an additional articulated structure that promotes a greater extension of the footrest, acting from the sliding structure, which is replaced by another that has two rails instead of one, and the second rail houses a system of articulated arms , which trigger the second structure from the moment the system, when passing the limit point in relation to the ground, and starts advancing in relation to the first structure.
- Still another object and advantage of the present invention is the improvement in the leg and foot support structure applied to reclining chairs which allows the seat angle to be modified when the armchair moves from an initial position, without extended support, to the reclined one. It is a small structure that is attached to the seat of the armchair, and is connected to the footrest system by a pivoting arm, which is attached to the footrest activation lever. When the lever is turned to extend the support, the pivoting arm rotates together, lowering the seat.
- Figure 1 is a perspective view of a conventionally known leg and foot support structure mounted adjacent the seat structure and a support base of a reclining chair; this structure being in its fully extended condition relative to the seat structure;
- Figure 2 represents another perspective view of a conventionally known leg and foot support frame mounted adjacent the seat structure of a reclining chair; this structure being in its fully extended condition relative to the seat structure;
- Figure 3 is a perspective view of the improved leg and foot support structure to be applied to reclining seats, which structure in its fully extended condition is mounted on the seat structure which in turn is mounted on the seat support base. solo of this reclining chair;
- Figures 4, 5 and 6 show the same perspective view of the improved leg and foot support structure being applied to recliners, which structure is in different stages of partial retraction with respect to the seat structure which in turn is seated. mounted on the ground support base of this recliner;
- Figure 7 represents the same perspective view of the improved leg and foot support structure to be applied to reclining chairs, the structure being in its fully retracted condition and concealed under the seat structure which in turn is mounted on the base. floor support of this reclining chair;
- Figure 8 is a disassembled view of the reclining chair base assembly with the improved leg and foot support structure, illustrating the possibility of mounting different support bases and support columns of different heights to the same armchair structure. ;
- Figure 9 is an enlarged perspective view of the support base frame with different support column sizes to be selectively fitted between it and the reclining seat floor support;
- FIGS 10, 11, 12, 13 and 14 are detailed and enlarged views of the locking rod and articulation system that is mounted on the lateral of the armchair seat frame, acts alongside the leg and foot support structure to selectively grade the seat height relative to the ground and the plane of the reclining armchair seat; and
- Figures 15, 16, 17, 18 and 19 represent enlarged detail views of the electric actuator drive mechanism of the improved leg and foot support structure to be applied to reclining seats, which actuator is in different positions according to with the stages of retraction of the leg and foot support structure relative to the seat structure of the recliner.
- leg and foot support structure applied to recliners, object of the present invention is carried out in structures of the type defined in figures 1 and 2, where from the seat structure 10 a second inner sliding frame 20b of a maximum length equal to the length of the rigid quadrangular horizontal frame is slidably mounted, said second sliding frame 20b being provided with an anterior cross member 23, said second sliding frame 20b moving parallel to one another.
- first frame 20a defining a retractable leg and foot support assembly.
- this inner sliding frame 20 is composed of two quadrangular frames 20a and 20b sliding together by pivoting articulated arms 1 and 2 the respective frames 20a and 20b and to a rigid articulated frame 20c which moves. angled downwards under the seat frame 10.
- the quadrangular frames 20a and 20b only begin their relative sliding after the angular displacement of the rigid articulated frame 20c has ended.
- the sliding frame 20a and 20b has two rails instead of one where the second rail houses a system of pivoting arms, which drive the second structure from the moment the articulated system, when passing through the limit point in relation to the ground, begins to advance in relation to the first structure. See figures 7, 6, 5, 4, and 3 in that order.
- Figures 3 to 7 further show the lever actuating mechanism 3 of the quadrangular leg and foot restraints 20a and 20b applied to recliners.
- This lever 3 allows you to modify the seat angle, not shown, when the seat moves from an initial position, without extended support, to the recline. It is a small frame that attaches to the seat of the armchair and is connected to the footrest system 20a and 20b via a pivoting arm 3a which is attached to the footrest drive lever 3. When the lever 3 is rotated to extend the support, the pivoting arm rotates together, lowering the seat.
- the purpose of this device is to make the seat remain horizontal when the seat is approximately upright, to an inclined position, more favorable for occupant relaxation, when the seat back is tilted and the footrest extended.
- Figures 8 and 9 show that the square frames 20a, 20b and 20c, whether actuated by lever or actuator, can be mounted on any type of support base 4.
- FIGS 10, 11, 12, 13 and 14 are detailed and enlarged views of the hinge system 7 and locking rod 8 which mounted on the side of the seat frame 10 of the armchair, acts next to the leg and foot support frame 20. for selectively grading the height of the seat relative to the ground and the plane of seat 10 of the recliner.
- a multi-slotted rod 8a is inserted between the levers of the system, together with a steel pin 8b that fits into these fittings 8a.
- this rod 8 fits pin 8b in varying positions, allowing the occupant to select the one that suits them best.
- this rod 8 is moved upwards by a spring, not shown, to free the return.
- figures 15 to 19 show a control alternative where the hand-operated lever is replaced by an electric actuator AE. It moves forward and backward to make the same course as the manual, with the advantage of offering an infinite number of footrest height positions.
