Abstract
A sole plate structure for an electric flat iron comprises a sole plate 1 with a channel 5 for the resistance heating element. A counter plate which forms a cover includes a channel 22 complementary to that of the sole plate for housing the resistance. A forced coupling is provided between the sole plate and the counterplate to force the element into continuous contact with the channels 5, 22, e.g. by studs 12 on the plate 1 being received in holes 28. <IMAGE>
Description
SPECIFICATION
Sole plate structures for electric flat irons
The present invention relates to electrically-heated sole plate structures for electric flat irons.
Sole plates for electric flat irons are usually either die cast in such a way as to incorporate the resistance heating element or formed with a channel adapted to house the element, and the sides of which are subsequently deformed or caulked one towards the other and against the element. The sole plates of the former type are efficient but relatively very costly, whereas those of the latter type are more economical, but the elements have a tendency to burn up in the presence of a difference in heat transmission from the elements towards the surrounding parts.
According to the invention, there is provided a sole plate structure for a flat iron heated by an electrical resistance heating element, comprising a sole plate including means defining a channel for receiving the element, a counterplate defining a cover, said cover including means defining a channel complementary to the channel of the sole plate and defining with that channel a seat in which the element is housed, and means for providing a forced coupling between said sole plate and said counterplate to force the element into continuous contact with the channels.
The coupling means may comprise studs or pins and holes, for the studs or pins to pass through, the studs or pins being riveted after coupling. The coupling means may also include an edge adapted to surround a slightly chamfered side and against which the edge is deformed or caulked.
Along the channels provision is advantageously made for mutual contact areas, which may also be inclined for mutual centring.
Further according to the invention, there is provided a sole plate structure for a flat iron heated by an electrical resistance heating element, comprising a metal sole plate, a metal cover applied tightly against the sole plate, the sole plate and cover including opposed channels which cooperate to define a seat, and an electrical resistance heating element within said seat and in firm contact with the sole plate and cover plate.
An embodiment of the invention will now be described, by way of example only, with reference to the diagrammatic drawings, in which:
Figure 1 is a plan view of a sole plate of a sole plate structure in accordance with the present invention;
Figure 2 is a section on line Il-Il of Figure 1;
Figure 3 is a plan view of a counterplate applied against the sole plate;
Figures 4 and 5 are sections taken on lines IV-IV and V-V of Figure 3;
Figure 6 is a section on line VI-VI of Figure 1; and
Figures 7 and 8 show, to enlarged scales, details of the two plates before and after coupling.
As illustrated in the accompanying drawings, a sole plate structure for a so-called steam-iron is constituted by a sole plate 1 and a counterplate 3 which is applied against the plate 1. The plate has, in an area in relief, a channel 5 within which the resistance heating element is to be housed. Channel 5 has a cross-sectional profile corresponding to part of the section of the element. In particular, in the embodiment shown, the channel 5 has a section which is approximately semi-circular and is flanked internally by a shoulder 7 and externally by a section 9 inclined in the manner of a ramp followed by a continuous edge 10. Adjacent the shoulder 7 there extends from the plate 1 studs or pins 12 (herein simply referred to as "studs") of frusto-conical shape and which are arranged at a distance one from the other in the manner shown in the drawings.The plate 1 is shaped to meet subsequent requirements; for example, the plate is provided with a peripheral edge 14 including an internal depression 16, and with an array of holes 18 for steam, and other pu rposes. The plate 1 may be made of aluminium or aluminium alloy, or other material, by die casting or in any other suitable way.
Against the plate 1, which forms the actual sole plate, the plate 3 which forms a cover 20 is applied, and which defines with the sole plate 1 a box able to house the element. In particular, the cover 20 has a channel 22, the configuration and cross-section of which are such as to define with the channel 5 when the cover 20 is coupled to the plate 1, a passage having a cross-section equivalent to that of the resistance heating element and which defines a seat for the element. The channel 22 is flanked externally by a chamfered edge 24 which is shaped to cooperate with the inclined section 9 of the external edge of the channel 5. The channel 22 is flanked internally by a shoulder 26 intended to engage with the shoulder 7 of the sole plate 1. In the shoulder 26 there are through-holes 28 which are of frusto-conical shape to receive the studs 12 of the plate 1.The holes 28 are distributed in the same way as the studs 12. The cover 20 is shaped peripherally, on the side opposite the chamfering 24, with a peripheral edge 30 which is slightly inclined for the purposes indicated hereinafter. The cover 20 is further shaped as shown on the drawing, for the needs of the design of the flat iron not relevant to the invention.
The electrical resistance heating element is dis posed in the channel 5 and the cover 20 is then cou- pled with the sole plate 1 in such a manner that the shoulder 26 is applied against the shoulder 7, the studs 12 enter the holes 28 and protrude beyond the cover, the chamfered edge 24 is applied against the inclined section 9, and the edge 10 surrounds the periphery of the cover 20, extending in front of and above the edge 30. The cooperating inclined surfaces 9 and 24 facilitate a mutual centering action.
The coupling is made secure by caulking or deforming the edge 10 against the peripheral inclined edge 30 of the cover 20, andlor by deforming the projecting ends of the studs 12 in the manner of rivets against the upper surface of the cover 20. In this manner the element remains embedded and forced in uniform manner between the channels 5 and 22, in such a manner as to transmit evenly the heat to the metal mass constituted by the intimately coupled components 1 and 20.
The production of the two components and their coupling may be effected in very easy and economic manner, and the coupling is very secure.
The sole plate structure features particular efficiency and reliability (also with regard to the life of the resistance) and substantial economy of production. In addition, wastage is reduced to a minimum.
