It should be noted, however, that the positions of bumper guards 1, 2, 3 and 4 noted above are for illustration purposes only, and thus guards 1, 2, 3 and 4 may be employed at other locations along docks or piers (with the possible exception of corner guard 4) depending upon the particular structural features and dimensions thereof. 1, bumper guard 1 of the first embodiment may be utilized horizontally between piles 5 on the side edges of the platform while bumper guard 2 of the second embodiment may be employed vertically on the piles 5 themselves with bumper guard 3 of the third embodiment extending horizontally along the front edge of the platform, and bumper guard 4 of the fourth embodiment extending horizontally to wrap around and cover a corner of the platform. The platform is composed of a plurality of slats 6 supported by a pair of opposite side joists 7 (only one of which is shown) and a front or end joist 8. As illustrated, the dock or pier includes a plurality of spaced vertically extending piles 5 supporting a platform therebetween. 1 illustrates a dock or pier incorporating four different embodiments of the bumper guard of the present invention generally designated by the numerals 1, 2, 3 and 4 respectively. Additionally, such materials allow the bumper guard to conform to nonuniform surfaces which typically occur at dock and pier locations. Such material distributes the load on impact of a boat and urethane material, which is preferred, spreads out on impact to cover and seal off the top or head of the fastener. The body is preferably composed of a urethane material, but other flexible, resilient material may be utilized. Preferably, the first portion of the body opening is cone-shaped and converges toward the shoulder portion to provide for ease of assembly. This enables the head of the fastener to be recessed from the boat-engaging surface to prevent it from scratching the boat finish. The body opening includes a first portion communicating with the boat-engaging surface, a second portion communicating with the dock-engaging surface, the first and second portions having different diameters, and a shoulder portion therebetween with the disk-shaped member disposed at the shoulder portion.
