A dock shelter adapted for mounting to a wall about an opening in the wall includes a plurality of coupled outer panels comprised of molded plastic. The plastic outer panels include a pair of roof sections as well as left and right lateral sections each coupled to a respective distal end of a roof section. Each lateral section includes respective pairs of upper and lower side panels coupled together in a telescoping manner to allow the height of the dock shelter to be fixed as desired over a range of values. Similarly, the roof sections are coupled together by means of a center roof connector cap in a telescoping manner to allow for adjustment of the width of the dock shelter. The telescoping coupling arrangement between the various dock shelter structural members allows the dock shelter to be used with a wide range of wall opening sizes. The plastic outer panels are sturdy and weather-resistant and each includes an outer angle portion to which either a head curtain or a side curtain may be attached so as to form a weather resistant, leak proof, outer structure for the inner dock shelter components which include a metal support/reinforcing structure and a pair of bottom pad seals. The plastic outer panels, formed by rotational molding in a preferred embodiment, are inexpensively fabricated, lightweight yet strong, and easily assembled and installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
1 and 2, there are respectively shown front planar and exploded perspective views of one embodiment of a loading dock shelter 10 in accordance with the present invention.
The loading dock shelter 10 includes a roof 12 and left and right side sections 22 and 24.
Left and right are used herein with the dock shelter viewed from the front.
The roof 12 includes left and right roof panels 12a and 12b as well as a center roof cap 12c.
The center roof cap 12c has a "peaked" center portion while the left and right roof panels 12a, 12b are tapered.
The tapered left and right roof panels 12a and 12b provide the roof 12 with a raked configuration and are each provided with a respective pair of spaced, elongated reinforcing ribs 32 and 34 for increased roof panel strength.
The center roof cap 12c is adapted for tight fitting positioning upon and coupling to the inner end portions of the left and right roof panels 12a, 12b.
The upper portions as well as the front and aft angle portions of each of the left and right roof panels 12a, 12b and the center roof cap 12c are provided with a plurality of aligned apertures which are adapted for receiving connecting pins 19 such as screws or bolts, by means of which the several roof panels may be securely coupled together to form a rigid, sealed structure.
By incorporating a plurality of spaced, aligned apertures in the center roof cap 12c as well as in the left and right roof panels 12a and 12b, the extent of overlap of the coupled roof panels may be varied depending upon the width of the doorway with which the dock shelter 10 is used.
In this manner, the various connected roof panels provide a telescoping capability for the roof 12 and allow its longitudinal dimension to be varied over a range of lengths.
Referring to FIG.
1a, there is shown another roof construction contemplated for use in the present invention.
In this arrangement, the roof 13 includes left and right side sections 15 and 17 which are adapted for insertion within respective slots 19a and 19b of an inverted, generally V-shaped center section 19
