[0001] The invention relates to a collapsible ironing board which can be erected and refolded
particularly easily and rapidly.
[0002] Ironing boards already on the market require the operator to use both hands in the
erection and refolding operations, as well as to bend down and pull or compress the
board and its legs. An example of such a boards is available from the document US-A-2
696 686. The present invention aims to obviate the above drawback, by providing an
ironing board which is extremely easy and practical to erect and refold, and which
does not require the operator to bend down. A board according to the invention is
defined by the features of claim 1.
[0003] Further characteristics and advantages of the present invention will better emerge
from the detailed description that follows, of a preferred but non-exclusive embodiment
here illustrated in the form of a non-limiting example in the accompanying drawings,
in which:
figure 1 is a schematic lateral view of the board in a partially folded configuration;
figure 2 is the lateral view of figure 1 in a different configuration;
figure 3 is a schematic frontal view in the configuration of figure 2;
figure 4 is a schematic perspective view in enlarged scale of a detail of the invention.
[0004] With reference to the figures, 1 denotes a support frame comprising a first leg 2
and a second leg 2', each provided with two uprights connected by crossbars 11.
[0005] The legs 2, 2' are connected one to another at upper ends by a pivot and are rotatable
about a horizontal axis X. The rotations are at least comprised between a closed position
of minimum frame 1 mass, wherein the legs 2, 2' are side-by-side, and an open position
wherein the legs 2, 2' are splayed and the frame 1 can rest erect on them.
[0006] The legs 2, 2' are immobilized in the open position by two support struts 9 pivoted
by one end to the uprights of the first leg 2. Each strut 9 is provided with an oblong
slot 10, in which one of the crossbars 11 of the second leg 2' is free to slide internally
along.
[0007] A board, constituting the ironing surface of the invention, is pivoted to the frame
1 and is rotatable about axis X; further, it is conformed such as to have its centre
of gravity positioned at the axis X, so that the rotation of the board is made easier.
[0008] During rotation, the board 3 assumes at least two configurations: one in which it
is folded (see figure 1) wherein it is associated with the first leg 2, and a work
position (see figure 2) wherein it is horizontal.
[0009] The stability of the board in the work position is guaranteed by a rod 4 hinged to
an end of the board 3 and slidable internally of a guide plate 5 mounted idle on a
horizontal shaft 7 hinged by its ends to the uprights of the first leg 2.
[0010] A cam 6 is rigidly and coaxially connected to the shaft 7 and is arranged such that
it is in contact with the rod 4. A command lever 8, perpendicular to and solid with
the shaft 7, enables a manually-commanded rotation of the shaft 7 and the cam 6 so
that the longer-radius zone of said cam 6 presses the rod 4 against the guide plate
5, achieving an immobilization of the rod 4 at a predetermined position, which is
to say a work position, in which the board 3 is horizontal.
[0011] In proximity of a hinging point, the rod 4 exhibits a bend 12 which, interacting
with the cam 6, enables the rod 4 to assume a minimum-mass position, with the board
3 parallel to the first leg 2.
[0012] In a further embodiment of the invention, not shown in the enclosed figures, the
rod 4 can be constrained by being hinged by one end to the frame while at another
end it is constrained to a runner mobile in guides predisposed on the board. Starting
from the closed configuration, whereat the board and the second leg 2' are side-by-side
with the first leg 2, the ironing board is opened as follows:
- a rotation of the second leg 2' about the first leg 2 up until the frame is open (figure
1);
- a rotation of the board 3, during which the rod 4 slides in the guide plate 5, up
until the work position of the board is achieved (figure 2);
- a fixing of the board 3 in the above position by means of a command lever 8.
[0013] The ironing board is refolded by reversing the order of the above operations.
[0014] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly such reference signs do not have any limiting effect
on the interpretation of each element identified by way of example by such reference
signs.
