Application January 22, 1936, Serial No. 60,331
1 Claim. (01. 20-2) This invention relates to a screened shelter of theknock-down type.
An object of the invention is the provision of a plurality of frames provided with screen wire which may be readily assembled or disassembled and packed in a neat bundle for transportation, means being provided for supporting a canvas covering upon the top and sides of the assembled frames.
. vision of a screened shelter of knock-down con struction in which a plurality of frames of substantially the same size are secured to a base frame along two sides and an end disposed in a'vertical manner, means being employed for removably connecting the side frames together with certain of the edges of said frames being complementarily grooved for forming a neat fit between said edges, the other end of the base frame being supplied with hinged frames forming a closure, top frames of substantially the same dimensions as the side frames being removably secured to the upper ends of the side frames, a support extending above the top frames which will retain the canvas covering in spaced relation with the top frames.
A further object of the invention is the provision of a screened shelter of knock-down type in which a plurality of frames of similar dimensions are rigidly secured together to provide the side walls, an end wall and a top, certain of the top frames being bowed for reinforcing the-top,
a raised support for a canvas covering being carried by the top.
This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claim;
In the drawing:
Figure 1 is a View in perspective of a screen shelter constructed in accordance with the principles of my invention,
Figure 2 is afragmentary transverse vertical section taken along the line 22 of Figure 1,
Figure 3 is a fragmentary horizontal section taken along the line 3-3 of Figure 1, and
Figure 4 is a fragmentary vertical section taken along the line 4-4 of Figure 1.
Referring more particularly to the drawing, I0 designates generally a base frame which may be ends, as shown at H.
Another object of the invention is the proformed of wood or metal and the parts of the frame are removably connected together at their In this instance the shelter is made rectangular. Therefore, there will be two similarly formed end bars l2 and two similarly formed side bars l3.
Each bar, as shown in Fig. 4, has an upstanding flange I4, a seat Hi and an inclined portion I6 extending inwardly towards the interior of the shelter so that the base frame provides a substantial foundation for the structure. I
A plurality of side frames 20 and 2| are'supported upon the seat l5 and the bottom bars 22 of these side frames are removably bolted, as
shown at 23, to the bars l3 of the base frame.
A Wing nut 24 is threaded onto the bolt 23.
An end bar 25 of each of the frames 20 is rectangular in cross section, as shown in Fig. 3, and is bolted at 26 to a side bar 21 of a front end frame 28 with a butt joint.
The other side bar 29 of the frame 20 is channeled to provide a rib 30 and a groove 3| to receive a complementarily formed rib 32 and a groove 33 of the side bar 34 of the frame 2|, and this construction produces what is known as a scarf joint. The other frame 2| is similarly constructed along its side edge. The rear end frame 20 is constructed similarly to the front end frame 20.
Bolts 35 are received by passages in the side bars 29 of the frame 2|] and the side bar 34 of the frame 2| so that when the nuts 36 are screwed up tight the corresponding ribs and grooves will be neatly fitted and prevent the passage of insects at these points even if there should be some warping of the frame rails.
The rear end of the shelter is closed by a plurality of frames 31, 38 and 39. The end frames 31 and 39 are constructed similarly to the end frames 20 of the side walls while the intermediate frame 38 is identical in construction with the intermediate frame 2| of the side wall so that the inner bars 40 and 4| of the end frames 31 and 39 and the side bars 42 of the intermediate frame 38 have complementarily formed ribs and grooves adapted to neatly interfit and bolts, as has been previously explained, are employed for drawing the adjacent side bars up right against each other.
The front end of the shelter has a pair of vertical end frames 28 and 28 The outer side bars of these two frames, as has been previously explained, are rectangular in cross section. The door frame 45 is hingedly connected at 46 to the inner side bar 41 of the front frame 28. This 5 door is grooved along its free edge as shown at 48 to receive a complementarily formed grooved portion on the inner bar 49 of the front frame 28.
The lower bars 50 of the front frames are bolted to the bar |2 of the base frame It].
A pair of top frames, generally designated by the numerals and 52, have their end bars 53 bolted as shown at 54 to the top bars of the side frames 20.
The outer side bar 56 of the rear top frame 52 is bolted, as shown at 51, to the top bars of the end frames 31, 38, and 39. A front top frame 5| has its outer side bar 60 secured to the top bars of the front frames 28 and 28 The intermediate top frames, generally designated by the numerals 6| and 62 have their side bars 63 either bowed or these side bars are formed of a wider strip of wood and sheared off from the central point towards the ends thereof. It will be noted that all of the frames are provided with screen wire'and the frames have countersunk por- .tions along their inner edges to receive the screen wire or the screen wire may be tacked upon the outer surface and the securing means for the screen wire covered by heading as indicated at 65. In view of the particular construction of the intermediate top frames 6| and 62, the screen wire is tacked upon the outer surfaces of the bars 63 so that the screen wire will be inclined at an angle towards the side walls of the shelter and form an intermediate portion of'the top frames 6| and 62. The particular construction of these frames provides for reinforcement of the top.
The frames 5|, 52, Gland 62 are all removably connected together by bolts and the intermediate frames GI and 62 have their end bars bolted to the top bars of the side frame 2|, as shown at 69.
A ridge pole is raised above the top of the shelter by means of standards 1| which are bolted, 5 as shown at 12, to the outer side bars of the top frames 5| and 52. These bolts at the rear of thei shelter also pass through the top bars of the intermediate frame 38.
An intermediate standard is mounted upon 10 the two adjacently. connected bars 63 of the intermediate top frames 6| and 62 and the top of this standard is cut so that it will be neatly received by the angular portion of these frames.
A pin 16 is carried either by the ridge pole 10 15 or the standards H and 15 for aiding in retaining the ridge pole on the standards.
A-canvas top covering 80 is stretched over the ridge pole and has its free ends 8| overhanging the side walls of the shelter.
If desired a canvas covering may be supported upon the side and front walls of the shelter and provision may be made for rolling the canvas to an inoperative position near the upper ends of the walls when the canvas covering is not desired or required.
In a screened shelter, an assemblage of upright screen frames, and a roof for said assemblage comprising top screen frames, at least one of the centrally located top frames being bowed upwardly to act as a truss and prevent the top frames from sagging downward.
