(01. Hill-36) 7 Claims.
This invention relates to new and useful improvements in sheltering devices for loading platforms and the primary object of the present invention is to provide a combined shelter and closure for loading platforms, wherein the same is readily moved from its closure forming position to its shelter forming position in a convenient manner.
Another important object of the present invention is to provide a combined shelter and closure for loading platforms involving a horizontal guide track that is secured to a building structure over an opening therein and which track slidably carries a pair of panels that may close the opening, the panels hingedly supporting panel sections that are extendable into the door opening of a car and one of the panels hingedly supporting a verticallyswingable roof forming panel that will be supported over and by the panel sections to form a covered entrance from the building structure into the car.
A further object of the prevent invention is to provide a combined shelter and closure for loading platforms, so constructed as to permit the same to be employed with cars whose bottom walls are disposed at difierent heights.
A still further aim of the present invention is to provide a closure and shelter structure of the aforementioned character that is simple and practical in construction, strong and reliable in to manufacture and install, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully 1775 hereinafter described and claimed, references being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a front elevational view of a building structure and showing the present invention mounted thereon and in its closure forming position;
Figure 2 is a view similar to Figure 1 but showing the invention moved away from the opening in the building structure;
Figure 3 is a view similar to Figure 2 but showing the device arranged in its shelter-forming position.
Figure 4 is an enlarged vertical sectional view taken substantially on the plane of section line 4-4 of Figure 3;
Figure 5 is a horizontal sectional view taken substantially on the plane of section line 5-5 of Figure 4;
Figure 6 is an enlarged view in horizontal sec tion taken on the line 6-6 of Figure 1, and
Figure 7 is an enlarged view in horizontal section taken on the line 7-? of Figure 3.
Referring now to the drawing in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It] represents a horizontal header that is mounted by fasteners l2 or the like, to the outer face of a building structure S over an opening 0 in the building structure. The header is is open at its bottom and overlies and shields a horizontally disposed guide track I i that is suitably secured over the opening 0 and i, to the building structure S.
A pair of vertically disposed horizontally slidable main panels i6 and is are supported by the guide track M and their upper ends support rollers 20 and 22 that engage the track It to form the means whereby the main panels i6 and it are slidably supported by the track.
The inner vertical edges of the main panels i6 and I8 are hinged, as at 24 and 2G, to the inner vertical edges of a pair of horizontally swingable auxiliary panel sections 28 and 3t that are swingable over the outer faces of the main panels it and it. The auxiliary panel sections 28 and 383 may be swung perpendicular to the main panels l6 and i8. Chains 32 and 3d are attached to the outer faces of the main panels l6 and 58 use, small and compact in structure, inexpensive and their free ends carry hooks 36 and 38 that will enter ears All on the auxiliary panel sections 28 and 30 to limit swinging movement of the auxiliary panel sections to a position perpendicular to the main panels l6 and i8 and parallel to each other.
Vertical extensions it and st are provided for the auxiliary panel sections 2% and St). The extensions M and 46 are hinged, as at it and 5G, to the opposed or outer faces of the auxiliary panel sections 23 and 38. When the extensions 44 and 46 are not in use, they may be folded against the outer faces of the auxiliary panel sections 28, 39, however, when the extensions 4 and 46 are in use they will extend forwardly from the auxiliary panel sections.
The lower ends of the extensions id and viii terminate short of the lower ends of the auxiliary panel sections 28 and 3t, and have extension flaps 52 and 54 hinged thereto, as at 5% and 53. When not in use, the flaps 52 and 5d may be raised to contact the outer faces of the extensions Ml and 45.
A vertically swingable roof-forming panel Ed is hinged at one end, as at 62, to the upper end of auxiliary panel section 28 and includes laterally projecting side edge portions 64 and 66. The roof-forming panel 60 will extend between and will be supported upon the upper end of auxiliary panel section 30 when the auxiliary panel sections are disposed perpendicular to main panels I6 and I8. When the roof-forming panel is supported in this position, the innerside. edge portion 64 will extend upwardly under the header it to prevent rain from entering the opening or the shelter formed'by the invention.
A roof-extension 68 is hinged, as at 10, to the outer edge portion at of the roof forming panel 50 and will overlie the panel Bil whennot in use.
hooks 36 and 38 are engaged in eyes 49 as shown in Figure '7. Extensions-44 and 65 are extended forwardly of auxiliary panel sections 28, 30 and roof-panel 60 is' supported between and by said sections 28, 30. Extension 68 is swung forwardly and downwardly.
Extensions 44, 16 and roof extension 58 will extend into the opening'of a car C to shelter the loaders and articles beingmovedfrom the build ing structure into the car or from the car into the building platform.
