10 Claims.

My invention relates to new and useful improvements in doors, and more particularly to a door made up of a plurality of metal sections which are, in turn, light in weight and relatively cheap to-manufacture.

One of the objects of the present invention is to provide a door made up of a plurality of metal sections, which door will be especially suitable for small garages, twarehouses, steamer docks or other buildings where a light metal door of nre-proof construction and light weight is especially desirable.

Another object of the invention is to provide a door made up of a plurality of metal tubes that may either be rolled up into a cylinder over the top of the doorway or may be pulled back in an outstretched condition over the top of the doorway and then lowered, when desired.

Still another object of the invention is to provide a metal door made up of three different types of metal sections, that is. a head tube or top section, a number of intermediate sections, and a lowermost section. The lowermost section is designed to tightly rest on. a curved threshold plate to thus prevent any snow or rain from being blown under the door.

Still another object of the invention is to provide a door that may be relatively light in weight so that it may be raised by the employment of a small motor or may be raised by a chain and sprocket arrangement.

With these and other objects in View, the invention consists in certain new and 4novel Varrangements and combination of parts, as will hereinafter be more ully described and pointed out in the claims.

Referring now to the drawings showing one embodiment,

Fig. 1 is a vertical section of a portion of a garage and showing one form of installation of the door and the latter being in its closed position;

Fig. 1a is an enlarged detail sectional view of a portion of Fig. 1;

Fig. '2 is a front elevation of a door in place, the parts being broken in the center for convenience of illustration;

Fig. 3 is an enlarged detail sectional view on the line 3-3of Fig. 2, of one end of a tube mounted in the guideway;

Fig. 4 is a detail section showing shaft or tube;

Fig. 5 shows one of the intermediate tubes; Fig. 6 is a view showing the final tube adapted to fit over the threshold plate;

the head (Cl. 18S-46) the doorway is a channel 4 in which Iits the ends of the tubular sections 5, which will shortly be described in detail. The channel 4 curves near the upper edge of the doorway, as at 6,

and extends rearwardly, as at '7, as may be clearly seen.

In Fig. l, there may be seen a sprocket 8 at the rear of the,guideway which, in turn, is driven by a shaft and pinion 9, the shaft, in turn, being driven from the motor 12, which may be conveniently located. Over the sprocket 8 and two other sprockets 8' and 8" passes a chain 9' which, in turn, is to be connected to the upper and lower ends of the door, so that a driving of the sprocket 8 will raise or lower the door, as desired.

Of course, any form of connection with the motor and sprocket might be used and, if necessary, a reducing box or any other connection with the motor to. properly drive the sprocket may be utilized.

The electrical connection with the motor may be a box 13 located slightly to one side of the doorway and out in front of the door, so that if desired the driver of the automobile may reach 90 out and press a desired button to thus raise or lower the door by the operation of the motor.

I have not shown any specific type of control in this electrical box, and it willbe understood that any desired control may be used, sol that if one button is pushed, for instance, the door will raise and the motor automatically cut on? when the door has reached its upper limit, while, in the same way, if another button is pushed, the door may be lowered and the motor cut oi when the door has properly descended.

Referring now more specifically to the gist of the invention, reference is made to Figs. 4, 5 and 6, and referring specifically to Fig. 4, there will be seen a tubular section 14 which may be rolled or pressed out of a single piece of thin sheet steel. It ,will be noticed that the tube is not entirely circular, as there is an opening 15 for the reception of what I term the flange of an adjacent intermediate tube.

` the arcuate iiange 18.

Referring for the moment to Fig. 5, one of these intermediate tubes may be seen consisting of the tubular portion 16, the integral web 17, and The arcuate ange 18 will be slipped within the opening 15 of the tube 14. A succeeding intermediate tube 16 is shown in dotted lines in Fig. 5, and this succeeding tube being shown in an angular position to illustrate how the ends oi' the iianges 18 will at all times overlie the opening 15 of the adjoining tube, even though the same is in angular relation thereto. Any number of these intermediate tubes will be used, depending on the height desired for the door.

To form the bottom of a door, a final tube is used, which is somewhat similar to the others in that there is a tubular portion 20, the web 21, and the arcuate flange 22 on its upper portion. However, the bottom of this tube has a slightly raised portion 23 formed therein so that it may snugly t a threshold plate 24 that has the arcuate or dome-shaped portion 25 centrally thereof to thus form a tight joint with the threshold plate, as may be understood from Fig. 7.

Thus, it will be seen that the door is made up of the desired number of intermediate tubular sections, a head tube and a final tube, the final tube, in turn, resting upon a special form of threshold plate.

Now to substantially seal these tubes from the elements, that is, where. they flt within the guide channels at the sides, and to prevent any rain or snow from blowing in these side channels, I provide a number of little end blocks 26 that are to be riveted along the opposite ends of the tubes, that is, riveted to the webs of the tubular sections, so that these small end blocks will, in turn, snugly iit within the guides or channels to, in turn, sealthe door at these points from any rain that is driven against the door.

'Ihe tubes are preferably made from one piece ofv metal but it is within the scope of my invention to make these tubes out of a lighter metal, say of galvanized sheet metal or of two pieces of metal, crimped or soldered together to form the diiferenttypes of tubes desired.

In Fig. 8, I have shown a slightly different v arrangement of raising and lowering the door,

and in this instance the door, made up of the sections heretofore explained, passes up in channel guides 30 and there may bea shaft 31 with a sprocket thereon over which will pass a chain 32 to, in turn, be operated by a sprocket 33 with a handle 34 which may be located on the outside of the garage.

Besides placing the lsmall blocks formed of rubber or other suitable material to the webs of the various sections at the opposite sides of the door to form a seal with the channel, I may also insulate the webs of the tubes, as shown in Fig. 9. It will be appreciated that the circular part of the tubes form a dead air space, and by placing a strip 35 of rubber, fiber or cloth along the web and riveting it as at 36 or otherwise securing the insulation in place, the door as a whole will be well insulated to thus keep the garage cooler in summer and warmer in winter.

It is possible to roll this door into a relatively small compact cylinder, due to the manner in which the lower portion of the intermediate tube is formed, that is, the opening is not directly centrai of the bottom of the tube but from a point near the center upwardly about the periphery, as

may be clearly seen in Fig. 5. Thus, the tubes' form of lock may be usedfof course, to lock the may swing at a substantial distance from the vertical, as is shown by the dotted line position in Fig. 5. Therefore, the door as a whole may be rolled into a relatively compact cylinder. Any

door in its closed position. From the foregoing, it'will be seen that I have devised a door that is made up of a plurality of tubular metal sections consisting substantially of a head tube, a plurality of intermediate tubes and a final tube and the tubes so arranged that the door as a whole may be rolled into a rather compact cylinder or may be drawn quickly up over the doorway in conveniently arranged guides.

Furthermore, it will be seen that the door will be practically storm-tight, as the guides or channels at the side, together with the small end blocks, will present a rather snugflt for the door, while the arrangement of the threshold plate, together with the final tube, will keep the rain from blowing in under the door.

Also, the door is one that is well insulated against heat and cold.

I am aware that it is old to make doors of various sections and do not claim my 4invention broadly as such.
