Supplemental bumper apparatus attachable to a water craft

Abstract

A supplemental bumper apparatus for covering the bumper of a personal water craft and providing enhanced shock absorption and blemish resistance. The supplemental bumper apparatus comprises a synthetic rubber body and a fastener system. The synthetic rubber body provides a barrier which can absorb shock and block blemishes from an impact. The synthetic rubber body is attached to the bumper fastener system defined by a plurality of snap fasteners on its upper section and a hook and loop fabric fastener is on its lower section. A plurality of snap fastener base members are permanently attached to the bumper and a corresponding hook and loop fastener material is permanently attached to the bumper, each providing a corresponding engaging member to enable the snap fasteners and the hook and loop fastener surface to attach the synthetic rubber body to the surface of the bumper.

DETAILED DESCRIPTION OF THE INVENTION

(9) Referring now to the drawings and in particular FIGS. 1, 2, and 3, a supplemental bumper apparatus 10 built in accordance with a planar embodiment is sized to be placed over the bumper 11a of a personal water craft 11. The supplemental bumper apparatus 10 is defined by a synthetic rubber body 10a and a fastener system. In the preferred embodiment, the synthetic rubber body 10a is constructed of an ethylene propylene diene monomer (“EPDM rubber”) and the fastener system includes a plurality of snap fasteners 12 and a hook and loop fabric fastener surface 13. Due to its construction of EPDM rubber and its placement directly over the bumper 11a, the synthetic rubber body 10a provides a reduction in how much shock is received and thus absorbed by the bumper 11a of the personal water craft 11. This reduction in shock results in less damage to the bumper 11a and the personal water craft 11 in the event of a collision. In addition, the synthetic rubber body 10a provides a barrier which can receive scratches and other blemishes from an impact in lieu of the bumper 11a. As such, the bumper 11a can remain relatively blemish free. Such a reduction in damage and blemishes enables the bumper 11a to have a longer effective life while on the personal water craft 11.

(10) The synthetic rubber body 10a is attached to the bumper 11a fastener system defined by two discrete fastener systems. A plurality of snap fasteners 12 are employed on the upper section of the synthetic rubber body 10a. A hook and loop fabric fastener 13 is employed on the lower section of the synthetic rubber body 10a. Before the synthetic rubber body 10a can be attached to the bumper 11a, a plurality of snap fastener base members 12a are permanently attached to the bumper 11a, oriented in a corresponding manner relative to the snap fasteners 12 on the synthetic rubber body 10a. In addition, a corresponding hook and loop fastener material 13a is permanently attached to the bumper 11a, oriented below the snap fastener base members 12a such that when the snap fasteners 12 of the synthetic rubber body 10a are engaged to the snap fastener base members 12a, the hook and loop fastener surface 13 will engage the corresponding hook and loop fastener material 13a. By the engaging of the snap fasteners 12 with the snap fastener base members 12a and the hook and loop fastener surface 13 with the hook and loop fastener material 13a, the synthetic rubber body 10a is attached to the surface of the bumper 11a.

(11) It is contemplated that the synthetic rubber body 10a is sized in the preferred embodiment to directly correspond to the size of the bumper 11a so as to enable the base body to cover the bumper without encroaching over the remainder of the personal water craft and affecting the aerodynamics of the body of the personal water craft.

(12) Referring now to FIG. 4, in an alternate embodiment, the synthetic rubber body of a supplemental bumper apparatus 40 is permanently attached to the bumper 41 through a plurality of bolts 42 which penetrate the synthetic rubber body and the bumper 41.

(13) Referring now to FIGS. 5, 6, 7, and 8, a supplemental bumper apparatus 50 built in accordance with an arcuate embodiment is sized to be placed over a protruding lip of a bumper 61 on a personal water craft 60. The supplemental bumper apparatus 50 is defined by a synthetic rubber body 51 and a dual fastener system. The synthetic rubber body 51 defines an arcuate member having a top side 52 and a bottom side 53. As with the planar embodiment, the synthetic rubber body 51 may be constructed of EPDM rubber.

(14) The synthetic rubber body 51 is secured to the personal water craft 60 through a dual fastener system which includes a plurality of top fasteners 54 and a plurality of bottom fasteners 55. In one embodiment, the top fasteners 54 and bottom fasteners define elongated mechanical fasteners, such as bolts, nails or screws. The top fasteners 54 operate to secure the synthetic rubber body 51 to a target bumper 61 by engaging the top side 52 of the synthetic rubber body 51 and the target bumper 61 at an obtuse angle (referred to herein as a “fastening angle”) relative to the top surface of the protruding lip of target bumper 61 and surface of the hull of the personal water craft 60. It is contemplated that by orienting the top fasteners 54 at the fastening angle, the synthetic rubber body 51 is less likely to sag (better able to resist gravitational force and impact from water than the fasteners being vertically engaging) or otherwise lose is positioning over the target bumper 61 over a time period of use. The bottom fasteners 55 operate to secure the synthetic rubber body 51 to a target bumper 61 by engaging the bottom side 53 of the synthetic rubber body 51 and the target bumper 61 at a right angle (referred to herein as a “vertically”) relative to the bottom surface of the protruding lip of target bumper 61. It is contemplated that the bottom fasteners 55 are positioned vertically to ensure a tight, secure fit (noting that from this orientation gravitational forces would have less of an impact).

(15) It is appreciated that in the arcuate embodiment, the synthetic rubber body 51 is positioned over the target bumper 61 such that an absorption space 56 (1½ inches to 2¼ inches in one embodiment) is left between the distal end of the lip of the bumper 61 (relative to the personal water craft 60) and the synthetic rubber body 51. This absorption space 56 increases the shock absorption capability of the supplemental bumper apparatus 50 beyond what is provided by the material of the synthetic rubber body 51.

(16) In yet another embodiment, the synthetic rubber body of a supplemental bumper apparatus is permanently attached to the bumper through an adhesive.

(17) In still another embodiment, the synthetic rubber body is sized to cover additional surface area exposed to collisions on the personal water craft beyond the bumper.

(18) The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
