E. G. BAKER SWIMMING AID Aug. 21, 1962 Filed Jan. 28, 1959 INVENTOR Y Eo GHP 6. Bfr/5R .w In" Unit@ ware Filed Jan. 28, 1959, Ser. No. 789,657 Claims. (Cl. 9-337) My invention relates to a swimming aid which is light, compact, comfortable, and durable and more particularly to a swimming aid which is particularly adapted for use by persons engaged in aquatic sports.

Aquatic sports, such as water skiing, `aquaplaning and the like, have become extremely popular. Inherent in participation in sports of this nature is the danger that the rider or skier may fall from the skis or the like while traveling over deep water at some distance from the shore. It is desirable for the safety of the skier that, even if he be an expert swimmer, he should be provided with some assistance in remaining aoat until he can reach shore or until he is picked up by the towing boat.

Many forms of life preservers are known in the prior art. For the most part, these devices are bulky, cumbersome, and uncomfortable. They do not permit the wearer sufcient freedom of movement for him to engage freely in active sports, such as water skiing and the like. These preservers of the prior art are not intended for repeated use but are intended only for emergency use. They are not constructed to withstand the shocks and abuse incident to everyday athletic use. The buoyancy of these bulky preservers of the prior art is many times greater than that which is necessary merely to assist a swimmer in staying aoat for a sucient time to permit his to reach safety. Owing to their bulk and marmer of construction, these life preservers of the prior art are unsuitable for use by a person engaging in active water sports.

I have invented a comfortable and compact swimming aid which reduces the effort required in swimming while affording the wearer great freedom of movement when engaged in active water sports. My swimming aid assists a fallen water skier or like person in remaining afloat until he reaches safety. My device can withstand the abuse incident to its use by a person regularly engaged in active sports.

One object of my invention is to provide a swimming aid which is especially adapted for use by a person engaging in active aquatic sports, such as water skiing and the like.

Another object of my invention is to provide a swimming aid which is less bulky than are life preservers of the prior art.

A further object of my invention is to provide a swimming aid which is less cumbersome than are life preservers of the prior art.

Still another object of my invention is to provide a swimming aid which is durable to permit its repeated use by a person engaging in active water sports.

Yet another object of my invention is to provide a swimming aid which reduces the effort required for swimming.

Other and further objects of my invention will appear from the following description:

In general my invention contemplates the provision of a swimming aid having a pair of mol-ded elongated channel-shaped iioats. I provide the bases of the floats with spaced openings to permit a length of webbing to be passed through the openings to form a belt by means of which my swimming aid may be secured firmly and comfortably around the waist of the wearer.

In the accompanying drawings which form part of the instant specification and which are to be read in conjunctates Eatent ice tion therewith and in which like reference numerals are used to indicate like parts in the various views:

FIGURE l is a perspective view illustrating my swimming i id in use by a water skier. f

FIGURE 2 is a perspective view of my swimming aid when detached from the body of the wearer.

FIGURE 3 is a sectional View of my swimming aid taken along the line 3-3 of FIGURE 2 and drawn on an enlarged scale.

FIGURE 4 is a sectional View of my swimming aid taken along the line 4 4 of FIGURE 3 and drawn on an enlarged scale.

Referring now more particularly to t-he drawings, my swim-imng aid, indicated generally by the reference character 1G, includes a pair of floats 12 and 14, which are molded from a suitable material such, for example, as foam rubber or the like. I form the elongated oats 12 and 14 with a channel-shaped cross section to provide each float with a base 16 and sides 18 and 19. I provide the base 16 of the float 14 wit-h a pair of spaced openings 20 and 22. The base 16 of the iioat 12 has a pair of openings 24 and 26 formed therein.

A length of webbing 2S, made of any suitable material such as cotton, nylon or the like, forms the belt of my swimming aid. Beginning with the end 30 of the length of webbing 28 remote from the free end 32, I pass the webbing through the opening 22 in the base 16 of the oat 14 and along the iiat underside of the base of float 14 to the opening 2G. I next pass the length of webbing 28 upwardly through the opening 26. The webbing next passes through the opening 26, then along the at underside of the base 16 of float 12 and upwardly through the opening 24.

I form a loop 34 in the belt and retain the loop in the belt by stitching 3U or by any other appropriate means. The loop 34 retains a pair of rectangular members 38 and 40, forming the buckle of my swimming aid on the belt. I pass the length of webbing 28 back through the channels of floats 12 and 14 to leave a free end 32, which may be secured by the buckle made up of members 3-8 and 40 to retain the swimming `aid on the wearers body in a manner to be described. Stitching 42 secures the length of webbing 28 passed back through the channels of the floats 12 and 14 to the portion of the length of webbing extending along the channels between openings 20 and 26. Stitching 44 secures the length of webbing 28 extending back through the channels of the fioats 12 and 14 to the end 30 to hold the iioats 12 and 14 firmly on the belt. This manner of assembling the iioats to the belt of my swimming aid enables the device to withstand severe abuse without damaging the floats.

In use of my swimming aid, a water skier or a person engaged in any other water sport of a similar nature wraps the floats 12 and 14 around his waist and passes the free end 32 of belt 2S through both members 33 and 4t?. The free end then is looped around the member 38 and is passed through the member 40 to cinch the swimming aid tightly about the waist of the wearer as tension is exerted on the free end of the belt. It will be appreciated that when the swimming aid is drawn around the waist of the wearer as shown in FIGURE 1, the flat undersides of the floats 12 and 14 conform themselves to the wearers body. The portions of the fiat webbing belt 2S extending along the undersides of the oats 12 and 14 between the pairs of openings 2t)` and 22 and 24 and 26 permit this action without discomfort to the wearer. My swimming aid is thus secured tightly to the Wearers body in a position in which it cannot interfere with his activity. At the same time it is extremely comfortable with the result that the user is scarcely aware of the presence of the aid. These results are accomplished by my swimming aid while permitting it to withstand great abuse in repeated uses without the danger of damage. It will be readily apparent that, owing to the elongated channel shape of my buoyant members and to the fact that the belt is disposed in the channels of the members over an appreciable portion of their length, the buoyant members are securely held on the wearers person in the position they are intended to occupy. They will not readily become disarranged with respect to the belt, even when subjected to shock as when the wearer tak-es a heavy fall into the water. Should the person wearing the aid fall or be thrown #from the water skis or the like, my swimming aid affords him sufficient bouyancy to remain aoat until he reaches what may be a relatively distant shore or until he is picked up by the towing boat.

It will be seen that I have accomplished the objects of my invention. I have provided a swimming aid which is light, compact, and comfortable. My swimming aid does not interfere with the activity of the wearer and thus is especially adapted for use by a person engaging in an active sport, such as water skiing or the like. My swimming aid reduces the etort required in swimming and provides suicient bouyancy to permit the user to stay aoat until he reaches safety. My aid can withstand great abuse in repeated uses.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of my claims. `It is 'further obvious that various changes may be made in details Within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood that my invention is not to be limited to the specific details shown and described.
