March 17, 1970 COPING Filed April 16,` 1968 FREDERICK KATZMAN I ATTRNEYS United States Patent O 3,500,605 COPING Frederick Katzman. 1998 Rte. 22, Scotch Plains, NJ. 07076 Filed Apr. 16, 1968, Ser. No. 721,743 Int. Cl. E04c 2/38; E04f I9/02; E04h 7/02 U.S, Cl. 52-588 2 Claims ABSTRACT OF THE DISCLOSURE A coping for a swimming pool made of a nose-piece and an end-piece wherein the nose-piece has two channels into which two legs of the end-piece may be pivoted to snap-fitted engagement.
BACKGROUND OF INVENTION This invention relates generally to copings and specifically to copings especially adapted to surround the margins of swimming pools. Numerous swimming pool copings have been devised, usually having the same general configuration, i.e. a curved outer beaded edge smoothly sloping toward a rear edge. The general purpose of such a coping is to define the margin of the swimming pool and to enable those who desire to jump into the pool to firmly grip the edge of the pool with their toes.
Often these copings are designed to be used in connec tion with border strips. It is desirable that the points of attachment be concealed so that attachment screws or bolts may not injure those walking on the coping.
SUMMARY OF THE INVENTION It has been found that a two-piece coping can be devised wherein thenose-piece can be attached to the margin of a swimming pool and the end-piece can be snap-fitted intor rm locking engagement with the nose-piece, concealing the point of attachment and attachment screws and bolts. The end-piece will be firmly engaged with the nose-piece, yet upon the application of suitable pivotal pressure, can be unsnapped from its t with the nosepie'ce, when such disengagement is required. It may be readily re-engaged with the nose-piece after such disengagement.
These objects and advantages as well as other objects and advantages may be attained by the device shown by way of illustration of the invention in the drawings in which FIGURE l is a perspective view of a portion of a nosepiece of a coping;
FIGURE 2 is a perspective view of a portion of an end-piece of a coping; and
FIGURE 3 is a vertical sectional view of a coping assembled and attached at the marginal edge of a swimming pool; the dotted lines show the end-piece prior to being pivoted into snap-fitted engagement with the nose-piece.
PREFERRED EMBODIMENT Referring now to the drawings in detail, the swimming pool coping provides a nose-piece 11. The nose-piece has a generally vertical wall 12 at the inner end of the nosepiece. At the top of the vertical wall 12, there is a generally horizontal top wall 13 intersecting with the vertical wall 12 and extending rearwardly therefrom. At the point of intersection with the vertical wall 12, the nose-piece 11 has a first channel 14 under the horizontal wall 13. At the bottom of the vertical wall 12, there is a'generally horizontal bottom wall 15 extending rearwardly from the vertical wall 12. This bottom wall 15 is longer than the top wall 13 in order to provide an area for the insertion of attachment screws or bolts, indicated ice by the holes 16. There is a second channel 17 in the nose-piece 11 on the top of the bottom wall 15. The outer end 18 of the nose-piece 11 extends in an upward smooth curve and then curves downwardly under the outer end. It terminates in a pedestal foot 19. In front of the pedestal foot 19, there is a generally U-shaped channel defining a socket 20 for receiving the beaded edgeof a swimming pool liner at the outer end of the nose-piece and yfrictionally holding it in place.
The end piece 21 has a generally vertical wall 22 at its inner end. Near the top of the inner end of the vertical wall 22, there is a generally horizontal inward extension 23. At the inward end of the extension 23, there is a top lip 24 which is dimensiond to t or seat in the first channel 14' of the nose-piece 11. The extension 23 is dimensioned to lie under the top wall 13 with the end of the top wall 13 in abutment with the top of the vertical wall 22.
The end-piece 21 has a generally flat, outwardly extending top wall 25, that curves downwardly at its outer end 26. An inwardly turned support 27 is formed on the end of the outer end 26. Underneath the top wall 25, a dependent support 28 is provided to strengthen the end-piece 21.
As shown in FIGURE 3, the nose-piece 11 is attached to the outer margin of a swimming pool wall 29 by a 4bolt or screw 30. The end-piece 21 is then applied to the nose-piece 11 as shown by the dotted lines in FIGURE 3. The end-piece 21 is pivoted downwardly to the position shown by the solid lines at which time the lip 24 will seat itself'l in the rst chanel 14 and the bottom of the vertical wall 22 will seat itself at its lower end in the second channel 17, providing a firm interlock between the nose-piece 11 and the end-piece 21, concealing the attachment screws 30.
Should it be necessary to remove the coping, the application of judicious pivotal pressure to the end-piece 21 will cause it to pivot upwardly and disengage itself from the nose-piece 11, thereby disclosing the attachment screws 30.
While I have referred to the coping in terms of a swimming pool coping, slight modification thereof will adapt it to numerous other uses, such as marginal edges for railroad platforms, marginal edges for sidewalks, and with a special low profile, rather than an upwardly curved outer end, it can be used to define pedestrian crossings. A swimming pool liner 31 is shown in the socket 20.
The foregoing descrition is merely intended to illustrate an embodiment of the invention. The component parts have been shown and described. They each may have substitutes which may perform a substantially similar function; such substitutes may be known as proper sul stitutes for the said components and may have actually been known or invented before the present invention; these substitutes are contemplated as being within the scope of the appended claims, although they are not specifically catalogued herein.
What is claimed:
1. Acoping comprising (a) a front piece defining the nose piece of a swimming pool coping,
(b) a rear piece defining a complementary end piece of a swimming pool coping,
(c) a generally arcuate outer edge on the nose piece,
(d) a top wall on the nose piece merging smoothly with the arcuate outer edge and sloping downwardly to an inner edge of the nose piece,
(e) a generally vertical wall depending from the top wall near to the inner edge of the nose piece,
(f) a first channel under the top wall between the vertical wall and the inner edge of the nose piece,
(g) a generally horizontal bottom Wall at the bottom of the vertical wall extending in the same direction as the inner edge of the nose piece extends,
(h) a second channel on top of the bottom wall,
(i) a top wall, and outer edge and an inner edge on the end piece,
(j) a generally vertical wall depending from the top wall of the end piece, in spaced relation to the inner edge of the end piece,
(k) a lip on the inner edge of the end piece,
(l) the lip seated in the first channel of the nose piece,
(m) the bottom of the vertical Wall of the end piece snap fitted into the second channel.
2. The device according toclaim 1 and (a) the top wall of the end piece adjacent to the inner edge being oiset from the remaining portion of the top wall, and fitting under the inner edge of the nose piece.
