Application February 13, 1951, Serial No. 210,737
4 Claims. (Cl. 126-43) This invention relates to stoves and more parstands and supports by employing a knockdown.
type of.construction in which a body member and two side members, made preferably of lightweight metal, are formed from substantially rectangular shaped blanks with the ends of these members I being bent at right angles in the same direction,
and with the bent ends of the body member being formed with channels adapted to receive in snug fitting interlocking relation the two side members. This arrangement provides a miniature stove in which the channelled ends function as legs for the stove holding the flat surface of the body member in spaced relation to the surface on which the stove is positioned and in which the vertically disposed side members act as supports for the container or object being heated. After being used, the stove may be easily re-assembled as a box for storage of solid fuel tablets.
It will be apparent that an important feature I of the miniature stove of my invention is the simple knockdown construction. If one of the members is damaged, it may be replaced inexpenlocking features of the bent ends of the members of the stove, and a minimum of parts to be damaged -or broken. As will be readily appreciated,
the only real damage that would problably occur to the stove of my invention is the inadvertent bending of the three members which comprise the stove, and these members can easily be straightened for effective use of the miniature stove.
The advantages of the miniature stove of my invention will be clearly understood from the accompanying drawing in which:
Figure 1 is a perspective view of a miniature stove arranged in accordance with my invention, and showing a burning solid fuel tablet;
Figure 2 is a vertical cross-section taken on lines 22 of Figure 1;
Figure 3 is an exploded view of the miniature stove shown in Figure 1 with the two vertically disposed side members in disassembled relation to the body member;
Figure 4 isa modification of the miniaturestove shown in Figure 1, with the vertically disposed side members having their bent ends pointed in wardly; I
Figure 5 is a perspective view of the miniature stove in' re-assembled, folded position; and
Figure 6 is a perspective view of the folded miniature stove in partially open position.
Referring now to the drawing and moreparticularly to Figure 1, my new and improved mini ature stove comprises a body member In and two side members H and I2. These-members 10, II and 12 have ends 13, I4 and I5, respectively, bent in the same direction-at right angles to their main portions.
As shown clearly in Figures 2 and 3, the body member ID has the extending edges of its bent ends l3 folded outwardly approximately 180 to form channels l6 which are adapted to receive in snug fitting interlocking relation the side members II and [2.
As shown in Figure 3 the side members I l and I2 slide easily in and out of this interlocking relation with the bent and channelled ends l3 of the body member l0. These ends l3 of the body member I!) also serve as legs for the miniature stove and hold the main portion of the body member 10 in spaced relation to the surface on which the miniature stove rests. The side members II and I2 in interlocking relation with the channelled ends I3 of the body member ID act as supports for the container or object being heated. With the ends I4 and I5 turned outwardly, as shown in Figures 1, 2 and 3, it will be readily understood that this arrangement will provide a large support surface for the object being heated. However, when a small object is to be heated, the vertically disposed side members II and 12 may be inserted in interlocking relation with the ends 13 of the body member ID with the bent ends M and [5 turned inwardly to provide a relatively small support surface, as shown in Figure 4.
The side member l2, as shown in the drawing, is provided with lips I! formed by bending the extending edges of ends I5 inwardly approximately The side member I2 is thus adapted as a cover to receive in sliding engagement in its interior portion the body member I 0 enclosed within side member I I. As shown in Figures 5 and 6, the folded members l0 and II slida-bly arranged in side member 12 form a small box-like container in which four fuel tablets may be conveniently transported.
As shown in Figures 1, 2 and 4 any weight placed on the top of the stove merely puts compression on the two side members II and I2.
Since the compression strength of light gauge metal is comparatively high, it is readily understood that this type of construction will allow relatively heavy loads to be placed on the stove such as heavy pots or pans used for cooking or heating purposes.
It will be appreciated from the foregoing description, that I have provided an eflicient, easily constructed and assembled knockdown type of miniature stove. These stoves may be constructed with a minimum amount of material, are quite diflicult to damage because of the simplicity of structure, and, if damaged, are easily repaired or are capable of having any of the members replaced with interchangeable similarly arranged parts.
1. A miniature stove of the knockdown spa adapted for use with solid fuel tablets comprising a body member and two'side members adapted to be separably connected to said body member, said body member having two oppositely disposed edge portions bent at right angles in the same direction and then folded outwardly approximately 180 to form channels, each of said side members having a flat body portion and two oppositely disposed edge portions bent'at right angles in the same direction, the channels of said body member being adapted to receive the flat body portion-of said side members in snug fitting vertically disposed relation.
. 2. A. miniature stove as defined in claim 1 and further characterized in that the side members when disposed in the channels of said body mem- 1.1, ber are positioned so that the bent edge portions extend outwardly from said body member.
3. A miniature stove as defined in claim 1 and further characterized in that the side members when disposed in the channels of said body member are positioned so that the bent edge portions extend inwardly in partial enveloping relation with said body member.
4. A miniature stove as defined in claim 1 and further characterized in that one of said side members has its bent edge portions folded inwardly approximately 90 to form lips whereby said side member is adapted to slidably receive in covering relation said body member and remaining side member which are arranged together in folded relation.
