Abstract

A simple diving device, comprising the main elements of an air pipe, a float and a snorkel, wherein the float features sufficient buoyance as a life buoy, and an air pipe line which is connected with the upper air pipe in the upper portion and the snorkel in the beneath of the float. The present device makes the swimmer to be capable of diving within appropriate depth (about 2.5 meter or less) under the water surface, and breathing by means of the air pipe, the air pipe line, the snorkel and air inlet pipe of swimming face mask. Additionally, the float thereof can indicate the location of the diver, and is used as a life buoy.

Description

SPECIFICATION Simple diving device In summer season, people used to go to sea shore or river side for dabbling in the water. People are used to equipping with face masks, life buoys or inflatable plastic air mats, etc. Though the conventional face mask provides an air pipe therewith, owing to its structure and functions, users are limited to dive within 30 cm depth under water surface, and are not fitted to the diving fans.

There are many weeds, odd shape rocks or colorful sea fishes in the sea bottom near the rocky coast for the swimmers. Though the diving oxygen tank and the equipments for the professionai divers are available in the markets, they are too costly for the ordinary leisureers, and also they are too bulky and professional equipments to be used by the average divers. There is no low cost, easy carrying diving device available in the markets.

The main object of this device is to provide a simple diving device comprising an appropriate size float, an air pipe and a snorkel, for providing an air passage on to swimming for supplying fresh airto the divers, and making the divers to be capable of staying an appropriate depth beneath the water surface for observing the scene of the animals and botany on the sea bottom without the fear of the shortage of fresh air supply.

Another object of this device is to provide a simple diving device which can indicate the location of the diver by means of the float thereof for securing the safety of the diver.

A further object of this device is to provide a simple diving device, by which the divers can get rest and rescue by rising to the water surface and holding the float thereof whenever they get fatigue or are sprained their tendons.

The present invention will be further illustrated, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a preferred embodiment.

Figure 2 is an assembling view showing the elements of the preferred embodiment.

Figure 3 is a sectional view showing one embodiment of the float of this device.

Figure 4 is a sectional view showing another embodiment of the float of this device.

Figure 5 is a perspective view of the snorkel of this device in assembling with air pipe of face mask.

Figure 6 is a schematic view illustrating the usage of device.

This device comprises an air pipe, a float and a snorkel as the main elements. The air pipe (1) is a hollow reversed-U shape pipe with many perforated air holes (11) provided on the wall of the upper end thereof. An elastic floating ball valve (13) (Figure 3) is provided inside the air pipe at upper end and the lower end of the air pipe is engaged on the float (2).

The float may consist of the upper lid (21 ) and the body (22) which are engaged with screw threads, forms a considerably large vacancy inside so as to offer sufficient buoyance as a life buoy. An air line or passage is provided on the float (2) for delivering air through the air pipe (1 ) to the snorkel (4) and the air inlet pipe (A) on the face mask. There are ballasts posited beneath of the float to steady the float (2) to maintain the air pipe always on the upper position of the float (2) for sucking air.

As one embodiment of this device, the floating material (23) is filled into the inner space of the float (2), which can be of polyron, etc. (see Figure 3).

There are three stands (24) posited beneath the float (2), and the heavy metal plates (241) are preset on the bottom of the stands (24) as the ballasts. A hollow pipe (3) is provided in the inner space of the float (2), and connected with the air pipe (1) and the snorkel (4) (see Figure 2 and 3).

The snorkel (4) of the device consists of the pipe soft layer (41), hard coil layer (42) and the rubber layer (43). The connections of the snorkel (4) with the hollow pipe (3) and with the face mask air inlet pipe (A) are fastened with the joints (44).

The reverse-U shape air pipe (1) on the upper portion of this device can prevent sea water from pouring into the pipe to affect the divers' inhaling by the elastic floating ball valve (13). Due to the construction, the snorkel can be circled and free from being bent or knotted, and from sea water invasion.

In another embodiment of th is device, the inner part of the float (2) can be a hollow space as shown in Figure 4. In this situation, the inner space of the float can be used as part of air passage directed air in the upper air pipe into the snorkel (4).

Please refer to Figure 6, float (2) is a float on the water surface, the diver wears the face mask which is connected with snorkel (4), diving into an appropriate depth (about 2.5 Meters or less) without fear of oxygen shortage. The snorkel can be tied on the both sides of the face mask or the diver's waist to maintain his activity. The simple diving facility has the following functions and advantages: 1. Simple in structure, easy carrying, low cost and being suitable for the general users.

2. The float can indicate the location of the diver, let the life guards identify and rescue, and thus increase their security.

3. When the diver feels fatique, or is sprained his tendons, he ride up to the water surface to hold the float to prevent him from being drowned. The unskilled divers can also use this device without fear of unsafety.

To sum up, the embodiment of this device is the invention in its dimentional shape with innovative, sound and reasonable design, and features the aforesaid several functions with practicality, and further, it has paid sound consideration to the users' safety.

In above-mentioned description and figures of the present invention, such as the shape and construction of the float and the position of installation of the air pipe passage or line ... etc. are ones of examples to describe the present invention.

Any alternation which does not apart from the substantial spirit of the present invention will be considered within the boundary of this invention.

For example, the float may, if desired, contain a source of pressurized air which is connected by an air line to a demand regulator worn by the diver.

This arrangement has the same advantage as the illustrated embodiment but enables the diver to reach deeper depths without being encumbered by a heavy compressed air cylinder on his back.
