DESCRIPTION OF THE PREFERRED EMBODIMENT

(14) A steam iron and burn prevention apparatus according to a preferred embodiment of the present invention will now be described with reference to FIGS. 1 to 3e of the accompanying drawings. The steam iron and burn prevention apparatus 100 generally includes an iron body 110 and an iron guard 120 surrounding the iron body 110.

(15) With reference to FIG. 1b, the iron body 110 may include a bottom plate 112 and a top plate 114. A continuous side wall 116 may extend vertically between the bottom plate 112 and the top plate 114 to form the iron body 110. A groove 118, illustrated in FIG. 3e, may extend around the circumference of the side wall 116 substantially adjacent the bottom plate 112 for engaging with the iron guard 120 as described below. Additionally, various components for operating the iron, such as a handle 115 or temperature dial 117, for example, may be secured to the top plate 114.

(16) While the iron body 110 is shown as having a generally triangular shape common to traditional iron bodies, the iron body 110 may have any desired shape. Furthermore, the iron body 110 may be constructed of any appropriate suitable material, such as aluminum or steel.

(17) Referring now to FIG. 3a, the iron guard 120 may include an upper portion 122 and a lower portion 128, each designed to correspond to the shape of the iron body 110. As shown in FIG. 2e, the upper portion 122 may have a generally inverted U-shaped configuration having opposed vertical walls 123a, 123b, and a flange 123c extending therebetween, thus defining an open bottom 124 and an interior area 126. A projection member 125 (FIG. 2e) may extend from the flange 123 into the interior area 126 leaving space between the projection member 125 and the vertical walls 123a, 123b.

(18) A tongue 127 may extend inwardly from the innermost vertical wall (e.g., 123a) towards the iron body 110. The tongue 127 may be configured for receipt by the groove 118 when the iron guard 120 is secured around the iron body 110. Thus, the iron guard 120 may be maintained in a preferable position with respect to the iron body 110.

(19) The lower portion 128 may generally correspond to the upper portion 122 such that, in a retracted configuration the lower portion 128 fits substantially inside the upper portion interior area 126 as shown in FIGS. 2c-2f. As shown in FIGS. 2e, 2f, 3a, and 3d, the lower portion 128 may have a generally U-shaped configuration having vertical walls 131a, 131b, and a flange 131c (working surface contact member) extending therebetween, thus defining an open top 132 and an interior area 133. A projection member 134 (FIG. 2e) may extend from the flange 131c into the interior area 133 leaving space between the projection member 134 and the vertical walls 131a, 131b. Recessed areas 129 may form apertures in the lower portion 128. The recessed areas 129 may thus leave heightened areas 130 from which the biasing members 136 may extend as described below, and as illustrated in FIG. 3d.

(20) Biasing members 136 may be disposed on the projection members 125, 134 between the upper portion 122 and the lower portion 128. The biasing members 136 may be, for example, compression springs. At an extended position, illustrated in FIGS. 2a, 2b, and 2e, the basing members 136 may be in a normal, non-compressed state thus biasing the lower portion 128 away from the upper portion 122. In the non-compressed state, the lower portion 128 extends beyond the bottom plate 112 of the iron body 110 so that the iron body 110 is held away from the work surface.

(21) Exerting a force (e.g., force F at FIG. 2c) upon the iron body 110 (for example, at the handle 115) may cause the biasing members 136 to become compressed. With the biasing members 136 in a compressed state, illustrated in FIGS. 2c, 2d, and 2f, the lower portion 128 may be received inside the upper portion interior area 126. More particularly, the lower portion vertical walls 131a, 131b are received into the interior area 126 around the projection member 125 so that the biasing member 136 is held in the compressed state between the projection members 125, 134. In the compressed position, the lower portion flange 131e may be level with the bottom plate 112 of the iron body 110 so that the iron body bottom plate 112 may contact the work surface.

(22) When the force F is decreased a sufficient amount, the tension in the biasing members 136 may return to normal and the lower portion 128 may again be biased away from the upper portion 122.

(23) The biasing members 136 may be adhered to the projection members 125, 134 so as to keep the upper portion 122 and the lower portion 128 in communication with each other. Other alternate means for keeping the upper portion 122 and the lower portion 128 in communication may also be acceptable, such as, for example, string or chain that may prevent the lower portion 128 from falling away from the upper portion 122 but that may collapse when the lower portion 128 is in the compressed position. Or, in still another alternative, the biasing members 136 may be snuggly received around the projection members 125, 134 which may act to hold the basing members 136 in place and prevent the lower portion 128 from falling away from the upper portion 122.

(24) The iron guard 120 may be arranged as a first section 140a and a second section 140b. A first section proximal end 142a may be in hinged communication with a second section proximal end 142b. Thus, the iron guard 120 may be movable between a closed configuration (FIG. 1a) in which the iron guard 120 is coupled to the iron body 110 at the groove 118 and tongue 127 connection described above, and an open configuration (FIG. 1b) in which the iron guard 120 is displaced from the iron body 110. The hinged connection is further illustrated in FIG. 3b.

(25) In the closed position, a distal end 134a of the first section 140a may abut a distal end 134b of the second section 140b. The sections 140a, 140b may be held in the closed position with a latch 146, such as a spring latch as shown in FIG. 3c. The latch 146 may include an engaging portion 146a and a stopper portion 146b. In the closed position, the latch's engaging portion 146a may snap around the stopper portion 146b thus resulting in the latch being in a locked position. To open the sections 140a, 140b, a lever 147 on the engaging portion 146a may be pressed to release the engaging portion 146a from the stopper portion 146b. The sections 140a, 140b may then be disengaged from the iron body 110 by removing the tongue 127 from the groove 118. It shall be noted that other types of appropriate latching mechanisms may also be used to keep the sections 140a, 140b closed.

(26) In use, the iron guard 120 may be placed around the iron body 110 such that the tongue 127 is selectively nestled in the groove 118 and the latch portions 146a, 146b are engaged to hold the guard 120 in the closed position. With the biasing members 136 in the normal position, the lower portion 128 is biased away from the upper portion 122 such that the lower portion 128 extends beyond the bottom plate 112. The iron body 110 is then heated.

(27) While the biasing members 136 are still in the normal position, steam exiting from the iron body 110 may be allowed to exit through the apertures 129. When desired, a force F is applied to the iron body 110 sufficient to overcome the normal tension in the biasing members 136. The force F causes the lower portion 128 to be received by the upper portion 122 as described above. The bottom plate 112 may then be in contact with the working surface and the iron 110 may be used as desired. When the force F exerted on the handle is decreased, the lower portion 128 automatically returns to the extended position.

(28) It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
