Definitions

  • the present invention relates to the general technical field of devices designed to ensure the shaping of a textile article such as a garment, by subjecting it to the combined action of a heat treatment and a mechanical ironing treatment. .
  • the present invention relates to an iron, of the electric type comprising an ironing sole defining a bearing surface, a rear zone forming the heel of the iron, said iron having a center of gravity giving the appliance a stable working position. when the iron rests on the soleplate.
  • the irons comprise an ironing sole forming the main member of the iron and constituting the flat supporting element intended to come into contact with the linen.
  • the ironing soleplate is in thermal relation with heating means, for example an armored resistor, intended to carry the soleplate, made of metallic material, at high temperature in order to accelerate the heat exchange between the soleplate and the linen.
  • heating means for example an armored resistor, intended to carry the soleplate, made of metallic material, at high temperature in order to accelerate the heat exchange between the soleplate and the linen.
  • the latter is also conventionally extended on an ironing support, such as an ironing board, extending in a substantially horizontal plane.
  • Such irons are for example described in GB-A-2160229.
  • This document indeed discloses an iron provided with an inclined handle allowing a more natural holding of the iron when it is in its horizontal working position.
  • This iron also has a heel whose geometric characteristics are not defined, any more than the possible geometric relationship with the center of gravity of the iron.
  • This document discloses a conventional iron of the prior art, the heel of which has no particular function, except that which may serve as a stable support area for a vertical position of the iron in order to facilitate its filling. Such a position is obviously dangerous.
  • the design of the irons, as well as the position of their center of gravity is such that when the iron rests on the ironing board by means of its soleplate, it occupies a position of stable equilibrium, even when he is abandoned to himself.
  • the position of the center of gravity, generally under the handle of the iron, is relatively close to the sole and the median plane of the iron and such that the projection of the center of gravity is located in the support polygon of the iron which is represented by the surface entire sole.
  • the user is required to regularly divest the iron in order to be able to carry out various manipulations requiring the use of her two hands, namely for example moving, folding or turning the article to be ironed .
  • the iron is either placed horizontally and at a distance from the article to be ironed, on an appropriate support, or placed on the rear part of the iron forming the heel.
  • the heel of the iron must obviously be shaped and designed so as to be able to ensure a stable position of the iron when the latter rests on a substantially horizontal plane, the soleplate of the iron then being substantially close to a vertical position. .
  • the iron's center of gravity is far from the fulcrum, and the iron's support polygon is represented by the surface of the heel.
  • the rest position of the iron on the heel is a relatively dangerous position insofar as the surface of the heel is of modest size with respect to the largest dimension of the iron, and in particular with respect to the surface of the ironing sole.
  • the rest position of the iron on its heel can therefore be considered as not meeting all the safety criteria to which the users, the iron can in this position be more easily struck and fall or the cord of the iron pulled inadvertently, the unbalanced iron falling easily.
  • the need to place the iron at regular intervals or not, either vertically or horizontally in an area provided for this purpose constitutes a usage constraint perceived in a particularly negative manner by the user.
  • the correct positioning of the iron in its substantially vertical rest position nevertheless requires sustained attention on the part of the user, attention which decreases over time with fatigue and can be the source of risks of burns. or even iron scraps.
  • the continuous operation of passing from a vertical position to a horizontal position of an iron constitutes a movement which physically stresses the wrist of the user and leads to certain physical fatigue.
  • the object of the present invention therefore aims to remedy the various problems mentioned above, and to provide an iron whose stability and safety of use is improved, and comprising only one stable working position in normal use.
  • an iron comprising an ironing sole defining a support surface, a rear zone forming the heel of the iron and a center of gravity G giving the iron a position stable working when the iron rests on the sole, characterized in that the heel of the iron forms an unstable support area which is shaped and arranged geometrically with respect to the center of gravity G so that with reference to the horizontal plane and in the event of 'support on said plane of any of the unit areas of the unstable support area the projection of the center of gravity G on said plane is located outside the unstable support area.
  • Figure 1 shows a general schematic view of an iron according to the invention comprising an outer casing of plastic material forming a covering 1 in which is provided at its upper part, a handle 2.
  • the iron also comprises a ironing sole 3 which can be provided, according to a preferred version of the invention, with steam distribution orifices not shown in the figures.
  • the ironing sole 3 is, conventionally, made of a metallic material, such as aluminum, and defines a substantially flat bearing surface for the iron.
  • the iron according to the invention comprises all the elements essential for the normal operation of a conventional iron, such as a vaporization chamber, one or more heating elements and in particular a flat heating element such as that which is described in French patent application FR-92.00.970.
  • a conventional iron such as a vaporization chamber
  • heating elements such as a vaporization chamber
  • flat heating element such as that which is described in French patent application FR-92.00.970.
  • the iron according to the invention has a center of gravity G, located substantially along the median plane M of the iron and preferably in its lower part, that is to say in an area closer to the ironing sole 3 than to the handle 2.
  • a center of gravity G located substantially along the median plane M of the iron and preferably in its lower part, that is to say in an area closer to the ironing sole 3 than to the handle 2.
  • Such a geometric positioning is conventional in the prior art and allows the iron to occupy a stable working position on a horizontal plane support 4 when it is in pressing on the surface formed by the ironing sole 3. In this position, the ironing surface 3 forms the iron support polygon, the projection of the center of gravity G then necessarily passing through the surface represented by the ironing sole 3.
  • the iron according to the invention also includes a rear zone 5 forming the heel of the iron.
  • This zone connects the rear part of the ironing sole 3 to the upper part of the iron formed in this case by one end of the handle 2.
  • the heel 5 forms an unstable bearing area which is shaped and arranged geometrically with respect to the center of gravity G so that with reference to the horizontal plane, and in the present case to the bearing surface 4, and in the case of bearing on said plane, of any one unit areas constituting the unstable support area, the projection of the center of gravity G on said plane is located outside the unstable support area.
  • This characteristic therefore prevents the iron from stably resting on its heel, which therefore has a natural tendency to come to rest naturally, preferably flat, on the soleplate 3.
  • the heel 5 forms an unstable bearing area which is formed of several unit areas 5a, 5b, 5c for example, which s 'extend according to different extension plans from each other.
  • the unstable bearing area comprises at least one convex unitary area, and in particular three, constituting a series of zones 5a, 5b, 5c, alternately concave and convex.
  • the unstable support area begins at the junction with the rear part of the ironing sole 3 by a convexity zone 5a, facing outwards, followed by a concave zone 5b, itself followed by a convex zone 5c forming the end part of the heel 5 .
  • FIG. 2 illustrates a particular example of the possibility of positioning the iron.
  • the position shown in FIG. 2 when the housewife places the iron on the terminal end of the second convex zone 5c, the contact between this zone and the support surface 4 is punctual and the housewife cannot let go of her iron without that it tilts forward under the action of gravity so as to come to bear at least on the central part of the second convex zone 5c.
  • the projection of the center of gravity G on the support plane 4 is located outside the unstable support area represented by the area of the heel 5.
  • FIG. 3 illustrates the pressing of the iron according to the invention according to the zones 5a and 5c which are advantageously adjusted and whose contact lines define a polygon whose vertical coming from the point G is external to the polygon. This consequently corresponds to an unstable support zone of the iron which again tilts forward.
  • FIG. 4 illustrates an unstable position of the iron corresponding to a contact which is established in an area close to the ironing sole 3, for example at the level of the convex area 5a.
  • the projection of the center of gravity G is located outside the unstable support area, which contributes to initiating the tilting of the iron forward.
  • the shape of the iron in accordance with the invention, and in particular the specific shape of the heel 5 prevents the user from using the iron other than in the most stable of the device, ie resting on the ironing sole 3. This constitutes an additional safety factor since it has turned out that any position, even unstable, of the iron on its heel was considered to be dangerous and less stable than on the ironing sole 3. Furthermore, the possibility of eliminating the need to have at least one stable position of the iron on its heel makes it possible to confer on this zone additional technical functions, and in particular to place or house other elements or technical units there, necessarily arranged in another area of the iron.
  • the use of a rear zone of the iron necessarily forming an unstable bearing area implies providing with the iron the means necessary so that the latter rests on its ironing sole without the risk of burning the support or the laundry. iron when the iron is stopped.
  • the means necessary to fulfill this function can consist either conventionally in a specific rest zone on which the iron rests, or in an ironing sole 3 with low thermal inertia, such as that described for example in patent application n ° 93.13.304 by the same applicant, the content of which is considered to be incorporated into the present application.
  • the sole has a thickness of less than 1 mm and is integral with the body of the iron by means of a permeable stiffening structure and made of a thermal insulating material.
  • Such a soleplate allows an extremely rapid drop in temperature of the soleplate when the iron is stopped.
  • the iron is equipped with a means for detecting the movement of the iron enabling the stop, after a set time, for example after 3 seconds of immobility, to interrupt the power supply.
  • Another possibility is to feed the iron only when it is grasped as described in the French patent application No. 93.11624, the content of which is also considered to be incorporated in the present application.
