INDIVIDUAL DEVICE FOR AQUATIC PROPULSION

Abstract

A device that propels a swimmer to move above or below the water surface allowing it to ascend, dive or turns on its axis is disclosed. It allows great capability of movement in water, due to its control fins. This allows it to be used as a sport, recreational, water use item, such as diving or to equip lifeguards or water rescue teams that need to move at higher speeds.

Claims

1. A single device for water propulsion of the type that includes two pedals that move a fin and a main body attached to a bar that connects the device to the hip of the swimmer comprising: two rails attached bilaterally to the main body; two side plates attached in a sliding way to each of the rails; two brackets that attach the pedals to the side plates in a perpendicular way; a flexible material or hinge that attaches one end of the main body to the fin in a pivoting way; two rods that connect the brackets with the fin; and a semi-hoop attached to one end of the bar.

2. An individual device for water propulsion according to claim 1 wherein the fin is of the vertical tail type.

3. An individual device for water propulsion according to claim 1 wherein the semi-hoop has a variable horizontal control fin, which can be moved by means of angle-of-attack control levers, with handles.

4. An individual device for water propulsion according to claim 1 wherein the rods are connected to the fin by means of T-shaped supports.

5. An individual device for water propulsion according to claim 1 wherein the main body has a widening which stabilizes the device vertically

6. An individual device for water propulsion according to claim 1 the pedals have supports for the instep of the swimmer's feet.

7. An individual device for water propulsion according to claim 1 wherein the tail has at least one horizontal stabilizing fin on each side.

8. An individual device for water propulsion according to claim 1 wherein the bar has a size adjustment tube by means of adjusting the fastening bolts and nuts.

DESCRIPTION OF THE PREFERRED MODE OF EMBODIMENT

[0040] The present invention is an individual device for water propulsion of the type which includes two pedals (5) moving a fin (10) and a main body (1) attached to a bar (12) connecting the device to the hip of the swimmer.

[0041] The individual device for water propulsion is flat and plate-shaped and elongated with defined curves seen from the side, forming a main body (1). At one end of this plate, it contains two side plates (2) which are connected in a sliding way to each side of the main body (1) by means of two rails (3) which slide longitudinally and are connected bilaterally to the main body (1). Two pedals (5) are attached to these plates and are held by brackets (4) that support them to the side plates (2) in a perpendicular way. In the middle of the plate there is a hinge (7) or flexible material that attaches one end of the main body (1) with a fin (10) in a pivoting way. In a preferred embodiment this fin (10) can be of the vertical tail type, that is to say that it is pivoting from side to side by means of an axis that is arranged in a vertical way when the user uses the device in face down position.

[0042] At the hinge, the main body (1) has a widening (14) that stabilizes the device vertically to counteract the lateral effect of the fin (10). Then the body narrows to reduce the resistance of the water by a certain length and then widens again to end up in the fin (10), elongated and flexible which acts as a propeller fin.

[0043] At the height of the narrow part of the fin (10), on each side there is at least one horizontal stabilizing fin (11) that serves as a horizontal stabilizer to maintain the horizontal level and prevent the device's tail from sinking.

[0044] At the head of the side opposite the tail fin, a bar is installed that attaches the main body to a semi-arch (12) that holds the swimmer to its hip, giving the feeling that the device is an extension of its body.

[0045] At the end of the bar that holds a semi-arch (12) there is a semi-hoop (13) that holds the user by the hip. This semi-hoop is attached to one end of the bar (12). At the sides of the semi-hoop there are two variable horizontal control fins (15), which are moved by an angle-of-attack control lever (16) ending in some handles (17) to control the angle of attack thereof and can be moved independently of each other, thus allowing to ascend, dive or turns on its axis.

[0046] When the pedals (5), which are held by supports (6) for the instep of the swimmer's feet, are operated, extending and retracting them, with both feet alternately, they move two rods (8) which connect to the fin (10) by means of T-shaped supports (9) which are attached to the base of the fin (10), moving it from side to side. These two rods (8) are coupled with the T-shaped supports (9), and this gives a leverage action that multiplies the force to the action of the pedals. Thus also these two rods (8) attach the brackets (4) with the fin (10).

[0047] On the bar that holds a semi-arch (12) there is a size adjustment tube (18) to regulate the size of the swimmer (18) by adjusting the fastening bolts (19) and nuts (20).

INDUSTRY APPLICATION

[0048] The invention has application in the industry as it is a device which can be used to propel oneself in the water, whether for sports, recreational purposes, such as diving, underwater hunting, or as in-water rescue equipment for lifeguards or rescue teams at sea.

[0049] Wherever speed is required to move in the water.
