3 Claims.

The invention relates to an oven and more particularly to oven doors;

The primary object of the invention is the provision of an oven of this character, whether it be portable or a unitary part of a stove or the like, wherein its door on the opening thereof becomes concealed and such door. is of a novel construction so that when the same is 'closed heat will not escape from the oven compartment and the door may be opened and closed with dispatch and in an easy manner.

Another object of the invention is the provision of an oven of this character wherein the door is made up of a plurality of panels or sections, each of a definite specific construction, and supports rollers traveling in tracks therefor so that the door can be brought to a closed position and when opened will be confined within the oven body and out of sight so that there will be no projecting parts at the entrance opening to the oven compartment.

A further object of the invention is the provision of an oven of this character, which is simple in its construction, thoroughly reliable and efficient in operation, the door being movably supported and operates with minimum friction, eliminating sticking and resultant task in the opening and closing thereof, and also inexpensive to manufacture.

7 With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a front elevation of an oven constructed in accordance with the invention, the door being in closed position.

Figure 2 is a sectional View on .the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a view similar to Figure-2 showing the door open.

Figure 4 is a perspective view of one of the sectional parts of the door.

Figure 5 is a fragmentary vertical transverse sectional view through the door.

Figure 6 is an enlarged detail fragmentary horizontal sectional view through the door.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings with particularity,

the oven or the like comprises-an outside wall NIL-which is continuous throughout the front, back, sides, bottom and top. The front is formed with an entrance opening II to a compartment l2 used for baking, cooking or the like. This compartment [2 at the front portion thereof is entirely open and congruous with the entrance opening H, the open front of the said compartment 12 being receded properly from the plane of the front of the wall of the oven. Above and below the entrance H are channeled tracks 13 which extend immediately rearwardly of the entrance opening I l in parallel relation to the front of the oven and thence curve rearwardly and inwardly to one side of the compartment l2. These tracks [3 have curvatures to permit of the travel of a disappearing door from open to closing positions or vice versa, the door being hereinafter fully described.

The door involves a plurality of units, each including outside and inside panels or plates [4 and I5, respectively, which are spaced apart by an outwardly curved intermediate plate It, which is riveted at I! to the outside plate M and flanged at 18 to the inside plate 15. This inside plate 15 is formed with pintle sleeves I9 for a pintle 20. In this manner the units are linked or pivoted together for free flexing activity throughout the extent of the door.

Located between the upper and lower ends of the plates l4 and [5 are rollers 2| adapted for travel in the channeled tracks 13. These rollers are supported on stud axles 22 fixedly held in ears 23 formed on the said plates [4 and [5. Such rollers are preferably located centrally with relation to the unit involving the said plates l4 and I5.

It is preferable to have the tracks l3 arranged in offset guideways 24 with respect to the entrance opening and the outer plates M of the units of the door are provided with offset overlapped flanges 25, each cooperating with an adjacent edge of a plate l4 next thereto so that when the door is closed these plates 14 of the units will be in overlapping relation to each other and thereby prevent the escape of heat from within the compartment ll during the working of the oven.

At the outer side of the door is provided a handle 28 for convenience in manipulating the door to bring it to a closing or opening position, the entrance opening I I being a clearance for the said handle.

The door is preferably provided with a thermometer or temperature device 21 suitably mounted thereon and of any conventional construction.

The door, when carried to an opening position, is confined out of view within the oven, or, in other words, disappears therein and when brought to a closing position totally closes the entrance opening ll communicating with the compartment l2.

The door, by reason of its construction and mounting, operates in an easy manner and with the minimum friction.

What is claimed is:

1. A flexible closure, comprising a plurality of hingedly connected units, each of the units involving inner and outer spaced plates, an intermediate arched plate between said inner and outer plates, the arched plate being fixed to the outer plate and flanged to the inner plate, and rollers fitted between the inside and outside plate of each unit.

2. A flexible closure, comprising a plurality of hingedly connected units, each of the units involving inner and outer spaced plates, an intermediate arched plate between said inner and outer plates, the arched plate being fixed to the outer plate and flanged to the inner plate, rollers fitted between the inside and outside plate of each unit, and a flange formed at one edge of each outside plate and adapted to overlap an adjacent outside plate next thereto.

3. A flexible closure, comprising a plurality of hingedly connected units, each of the units involving inner and outer spaced plates, an intermediate arched plate between said inner and outer plates, the arched plate being centrally fixed to the outer plate and flanged at one edge to the inner plate, ears formed at the upper and lower ends of each unit on the inside and outside plates, rollers fitted between the ears and rotatably mounted therein, and flanges formed at one edge of each outside plate and adapted to overlap an adjacent outside plate thereto.
