Title:
COPING
United States Patent 3802140
Abstract:
The top of a parapet brick wall of a building is protected from the elements by a coping which is simple in construction and readily applied thereto. Inverted U-shaped anchor elements are secured to the wall at space points where the lengths of the coping units substantially abut. The anchoring element may be 6 to 8 inches wide and may be secured by nails or screws to the sides of the wall or preferably is anchored by an adhesive placed upon the bricks which is extruded through apertures in the anchor element. A drain shoe of plastic material is placed centrally of the anchor element to slope toward the inside of the wall and after a cover plate is hung in the front end of the shoe the coping unit is hooked over the front side of the anchor element and swung downwardly over the center of the shoe and hooked onto the end of the inner side of the anchor element. The ends of the coping units are spaced apart to permit water to pass therebetween down onto the shoe and drain to the inside of the wall onto the roof.

Description:
BACKGROUND OF THE INVENTION
Reference may be had to U.S. Pat. Nos. 818,122; 1,860,240 and 3,012,376 to disclose some teaching of the prior art.
SUMMARY OF THE INVENTION
The invention pertains to a parapet wall for a building which is sealed at the top by inverted channel shaped coping units, the adjacent ends of which are slightly spaced apart. A channel shaped anchor element has a web which spans the wall and two downwardly extending sides which have the ends sloping outwardly. The anchor elements are secured at spaced intervals along the wall which are substantially equal to the length of the coping units. The anchor elements are 6 to 12 inches wide and are secured in any known manner, such as by nails, screws and the like but preferably by an adhesive which will be extruded through apertures in the anchor elements. The apertures permit the rigid securement of the anchor elements and the removal of the solvent from the adhesive so that it will quickly dry.
A shoe made of plastic material of approximately one-half the width of the anchor elements is placed thereupon to slope from the front to the rear surface of the wall. A cover plate is hung within a drain recess in the top of the shoe to extend downwardly over the front side of the anchor element down which water passing between the front side of the coping units may flow. The water between the web portions at the top of the wall will flow into the drain recess of the shoe and to the rear and onto the roof. The inner end of the shoe is flexible and after the hook on the front side of the coping unit is secured over the outwardly deflected flange at the bottom of the front side of the anchor element, the coping unit is swung rearwardly over the wall and pushed downwardly with the end of the shoe to engage the hook at the inner side over the flange on the inner side of the anchor element. This eliminates the cover plate at the top and inner side of the adjacent coping units and provides a clean and simple joint with the ends spaced apart approximately one-eighth inch to permit water to pass to the drain recess of the shoes, and to allow for thermal expansion of the coping channels.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A parapet wall 11 of a building has the top sealed by coping units 12 of the present invention. The coping units are of predetermined length such as ten feet and the anchor elements 13 are spaced the same distance apart when secured across the top of the wall. The anchor element has a web 14 the width of the wall, a front side 15 and a rear side 16 extending downwardly therefrom. The front side 15 has the edge provided with an outwardly sloping flange 17, the rear side 16 has the edge provided with an outwardly sloping flange 18. A molded styrene coping shoe 19 has a length which is substantially the width of the wall and of narrow width of approximately three inches. The shoe has a top drain recess 20 and is of greater height at the front end than at the rear end so as to slope from the front to the rear face of the wall. The shoe is placed centrally of the anchor elements 13 to rest upon a pair of longitudinal flanges 21 and transverse flanges 22 leaving the rear end 23 spaced above the anchor element 13 toward which it can deflect.
A cover plate 24 has a U-shaped hook 30 at the top which extends over the front edge of the shoe 19 into the recess therein and downwardly to cover the face of the shoe and the side 15 of the anchor element 13. The cover plate 24 has a flange 25 which mates with the flange 17 at the end of the side wall 15.
The coping units have a top web 26, a front downwardly extending side 27 and a rear downwardly extending side 28. The side 27 has an inwardly presenting hook edge 29 while the side 28 has a similar hook edge 31. After the anchor elements 13 have been secured at spaced points along the top of the parapet wall 11, the shoes 19 are placed centrally thereof and the cover plates 24 are hung downwardly from the front edge of the shoe over the side 15. A coping unit 12 has the ends of the hook edge 29 slid over the flanges 17 of the two adjacent anchor elements 13 and is hinged inwardly and downwardly over the top of the wall 11 until the hook edge 31 is deflected below the flange 18 on the inner side 16 of the two anchor elements 13. The rear end 23 of the shoe is resilient and urges the hook edge 31 upwardly into engagement with the flange 17. The ends of the coping units 12 are spaced apart approximately one-eighth to one-fourth inches and located above the recess 20 provided at the top of the shoe 19. Any rain passing downwardly between the adjacent edges of the coping units will collect within the recess 20 and flow therefrom over the inner side 16 and onto the roof. The space between the ends of the coping units at the front of the wall will be adjacent to the cover plate 24 over which the coping units extend. It will be understood that when the hook edge 31 is moved beneath the flange 18 of the anchoring element 13 that the end 23 of the shoe will be deflected downwardly to permit the engagement as illustrated in FIG. 2, which will be maintained when the coping unit is released by the upward urge of the end 23 of the shoe due to the resiliency thereof. The sheet of material from which the anchoring element 13 is made is preferably of galvanized steel having apertures 33 punched therethrough at the front side and over the greater portion of the web 14. The adhesive in the apertures firmly maintains the anchoring element across the top of the wall 11 in firm fixed relation thereto. The apertures may be small, approximately one-sixteenth inch in diameter and located at the corners of squares having sides one-fourth inch in length. The adhesive material is of the construction type which will adhere to the wall and which is procurable from Franklin Glue Company, 2020 Bruck Street, Columbus, Ohio 43207. This is a neophrene base adhesive which has proven satisfactory for securing the anchoring element to the wall. A rib 34 may be provided on the shoe beneath the recess 20 to eliminate the warping thereof.
Reference may be had to U.S. Pat. Nos. 818,122; 1,860,240 and 3,012,376 to disclose some teaching of the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A parapet wall 11 of a building has the top sealed by coping units 12 of the present invention. The coping units are of predetermined length such as ten feet and the anchor elements 13 are spaced the same distance apart when secured across the top of the wall. The anchor element has a web 14 the width of the wall, a front side 15 and a rear side 16 extending downwardly therefrom. The front side 15 has the edge provided with an outwardly sloping flange 17, the rear side 16 has the edge provided with an outwardly sloping flange 18. A molded styrene coping shoe 19 has a length which is substantially the width of the wall and of narrow width of approximately three inches. The shoe has a top drain recess 20 and is of greater height at the front end than at the rear end so as to slope from the front to the rear face of the wall. The shoe is placed centrally of the anchor elements 13 to rest upon a pair of longitudinal flanges 21 and transverse flanges 22 leaving the rear end 23 spaced above the anchor element 13 toward which it can deflect.
A cover plate 24 has a U-shaped hook 30 at the top which extends over the front edge of the shoe 19 into the recess therein and downwardly to cover the face of the shoe and the side 15 of the anchor element 13. The cover plate 24 has a flange 25 which mates with the flange 17 at the end of the side wall 15.
The coping units have a top web 26, a front downwardly extending side 27 and a rear downwardly extending side 28. The side 27 has an inwardly presenting hook edge 29 while the side 28 has a similar hook edge 31. After the anchor elements 13 have been secured at spaced points along the top of the parapet wall 11, the shoes 19 are placed centrally thereof and the cover plates 24 are hung downwardly from the front edge of the shoe over the side 15. A coping unit 12 has the ends of the hook edge 29 slid over the flanges 17 of the two adjacent anchor elements 13 and is hinged inwardly and downwardly over the top of the wall 11 until the hook edge 31 is deflected below the flange 18 on the inner side 16 of the two anchor elements 13. The rear end 23 of the shoe is resilient and urges the hook edge 31 upwardly into engagement with the flange 17. The ends of the coping units 12 are spaced apart approximately one-eighth to one-fourth inches and located above the recess 20 provided at the top of the shoe 19. Any rain passing downwardly between the adjacent edges of the coping units will collect within the recess 20 and flow therefrom over the inner side 16 and onto the roof. The space between the ends of the coping units at the front of the wall will be adjacent to the cover plate 24 over which the coping units extend. It will be understood that when the hook edge 31 is moved beneath the flange 18 of the anchoring element 13 that the end 23 of the shoe will be deflected downwardly to permit the engagement as illustrated in FIG. 2, which will be maintained when the coping unit is released by the upward urge of the end 23 of the shoe due to the resiliency thereof. The sheet of material from which the anchoring element 13 is made is preferably of galvanized steel having apertures 33 punched therethrough at the front side and over the greater portion of the web 14. The adhesive in the apertures firmly maintains the anchoring element across the top of the wall 11 in firm fixed relation thereto. The apertures may be small, approximately one-sixteenth inch in diameter and located at the corners of squares having sides one-fourth inch in length. The adhesive material is of the construction type which will adhere to the wall and which is procurable from Franklin Glue Company, 2020 Bruck Street, Columbus, Ohio 43207. This is a neophrene base adhesive which has proven satisfactory for securing the anchoring element to the wall. A rib 34 may be provided on the shoe beneath the recess 20 to eliminate the warping thereof.
