Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a diver's weight belt for underwater diving and more particularly, to an environmentally friendly weight block for diver's weight belt.

2. Description of the Related Art:

A diver normally will wear a diver's weight belt with attached weights to overcome the buoyancy force of water and to conveniently maintain a desired depth in the water. Lead weights are most commonly used for this purpose. When using a diver's weight belt, lead weights are directly fastened to the belt. When a diver is diving, the attached lead weights are directly dipped in seawater. Seawater corrosion acts on when the lead weights are exposed to seawater for long. When this happens, lead will be dissolved in seawater, thereby polluting the sea. Further, when seawater corrosion occurs, the lead weights will reduce their weight. Therefore, a diver must purchase new lead weights to replace corroded lead weights.

The quantity of lead weights required is determined by the overall positive buoyancy of the diver. However, regular weights for diver's weight belt are prepared in the range of 2 kg to 15 kg and in one same dimension and one same outer appearance. It is difficult to discriminate the weight measure when a number of weights are put together. Diving weights determine how a diver will ascend and descend into the sea. If the total weight of the diving weights does not match, the diving weights will be unable to offset positive buoyancy.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a weight block for diver's weight belt, which is made in the shape of one of the English letters for quick identification. It is one object of the present invention to provide a weight block for diver's weight belt, which can be conveniently fastened to or removed from a diver's weight belt. It is one object of the present invention to provide a weight block for diver's weight belt, which is environmentally friendly.

To achieve these and other objects of the present invention, environmentally friendly weight block for diver's weight belt is disclosed to include a weight formed of a lead block made in the shape of an English letter and coated with a layer of anti-corrosion plastic coating, and a clip or belt loop affixed to the back side of the weight for fastening to a diver's weight belt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-4, an environmentally friendly weight block for diver's weight belt in accordance with a first embodiment of the present invention is shown comprising a weight 1 and a clip 2.

The weight 1 is formed of a lead block 11 made in the shape of an English letter, for example, the English letter “A” as shown in FIG. 2, or the English letter “T” as shown in FIG. 4, and coated with a layer of plastic coating 12 for protection against seawater corrosion. Further, the weight 1 is prepared in the range of 2 kg to 15 kg.

The clip 2 has a first clamping plate 21 and a second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 are joined together, defining therebetween a gap 23 for receiving a diver's weight belt 3. The second clamping plate 22 is affixed to the weight 1 with screws 26. Further, the second clamping plate 22 has one end joined to the first clamping plate 21, and the other end terminating in a protrusion 251 and then a retaining tip 25. The first clamping plate 21 has one end jointed to the second clamping plate 22, and the other end terminating in a protrusion 241, which is abutted against the protrusion 251 of the second clamping plate 22, and a clamping tip 24 that is clamped on the retaining tip 25 of the first clamping plate 21. By means of bending the clamping tip 24 away from the retaining tip 25, the clip 2 can easily be fastened to the diver's weight belt 3 that is worm on the waist of a person (see FIG. 5).

FIG. 6 shows an environmentally friendly weight block for diver's weight belt in accordance with a second embodiment of the present invention. According to this second embodiment, the environmentally friendly weight block for diver's weight belt comprises a weight 1 and a belt loop 4. The weight 1 is formed of a lead block 11 made in the shape of an English letter, and coated with a layer of plastic coating 12 for protection against seawater corrosion. The belt loop 4 is affixed to the back side of the weight 1 with screws 26, defining therein a belt hole 41 for the passing of the diver's weight belt 3.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
