The invention relates to a collapsible support frame (1), particularly for ironing boards (2), comprising a ground bearing base (3), at least an arm (6; 6a; 6b) having one end linked with the bearing base (3) and the other end that can be restrained to the ironing board (2), and blocking removable means acting both on the arm (6), or on the arms (6a, 6b), and on the bearing base (3), and on the ironing board (2) to maintain said arm erected in a working position at an adjustable level above the bearing base (3), wherein said blocking removable means comprise at least two strut elements, one of which has its end articulated, when used, respectively one to said arm (6), or arms (6a, 6b), and the other one to said bearing base (3), while the other strut element is articulated, when used, to said arm (6), or arms (6a, 6b), and to the ironing board (2), and locking removable means to lock the position of said strut elements, each strut element comprising a plurality of plate-shaped element, packed by the interposition of a friction spacing element between two adjacent plate-shaped elements, and each one providing one end articulated to the arm (6) or arms (6a, 6b) or to the bearing base (3), or to the ironing board (2), the other end provided with a slot (13) for the loose articulation, to the bearing base (3) or to the ironing board (2), or to the arm (6), or arms (6a, 6b), respectively, and said locking removable means providing a tension rod (14), axially slidably mounted, and acting to engage the slots (13) and to pack said plurality of plate-shaped elements (8), elastic means (18) to load the tension rod (14), and an operation device, suitable to neutralize, upon activation, the elastic loading force of the tension rod (14), thus allowing the sliding displacement each other between plate-shaped elements (8) and tension rod (14), said collapsible frame (1) being characterized in that the plurality of plate-shaped elements (8) of each element is comprised of a group of sliding plate-shaped elements (8) and of a group of friction plate-shaped elements (8), each group of sliding plate-shaped elements (8) providing at least 7 elements and each of group of friction plate-shaped elements (8) providing at least 8 elements, each group of plate-shaped elements (8) of each strut element providing elastic means for packing the plate-shaped sliding elements (8) and the plate-shaped friction elements (8).
Collapsible support frame, particularly for ironing boards, comprising a ground bearing base, at least an arm having one end linked with the bearing base and the other end that can be restrained to the ironing board, and blocking removable means acting both on the arm, or on the arms, and on the bearing base, and on the ironing board to maintain said arm erected in a working position at an adjustable level above the bearing base, wherein said blocking removable means comprise at least two strut elements, one of which has its end articulated, when used, respectively one to said arm, or arms, and the other one to said bearing base, while the other strut element is articulated, when used, to said arm, or arms, and to the ironing board, and locking removable means to lock the position of said strut elements, each strut element comprising a plurality of plate-shaped element, packed by the interposition of a friction spacing element between two adjacent plate-shaped elements, and each one providing one end articulated to the arm or arms or to the bearing base, or to the ironing board, the other end provided with a slot for the loose articulation, to the bearing base or to the ironing board, or to the arm, or arms, respectively, and said locking removable means providing a tension rod, axially slidably mounted, and acting to engage the slots and to pack said plurality of plate-shaped elements, elastic means to load the tension rod, and an operation device, suitable to neutralise, upon activation, the elastic loading force of the tension rod, thus allowing the sliding displacement each other between plate-shaped elements and tension rod, said collapsible frame being characterised in that the plurality of plate-shaped elements of each element is comprised of a group of sliding plate-shaped elements and of a group of friction plate-shaped elements, each group of sliding plate-shaped elements providing at least 7 elements and each one of group of friction plate-shaped elements providing at least 8 elements, each group of plate-shaped elements of each strut element providing elastic means for packing the plate-shaped sliding elements and the plate-shaped friction elements.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said plate-shaped elements are comprised of iron C70, with a single trimming.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said plate-shaped sliding elements are comprised of iron, subjected to tumbler system galvanisation, thus eliminating the punching burrs.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said packing elastic means is comprised of an adiprene 95 spring shore D.25.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said frame provides a safety pedal as blocking means acting to maintain the arm erected on the bearing base, shaped in such a way to be necessary a semi-rotation of the same pedal before allowing the unlocking of the block.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said collapsible frame provides at least two wheels provided under said bearing base, and sliding on the ground when the collapsible frame is in a closed position, thus allowing its motion according to a transverse direction, and at least two wheels on said arm, in correspondence of its end articulated to said bearing base, sliding on the ground when said collapsible frame is closed, thus allowing its motion according to a longitudinal direction.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said operation device comprises a cam sliding engaging on one end of said tension rod and suitable to push the tension rod against the action of said elastic loading means, and a control lever for said cam.
Collapsible support frame, particularly for ironing boards, according to one of the preceding claims, characterised in that said lever provides a curve in correspondence of the pushing point of said elastic means.
