Field of the Invention
This invention relates to a leg handle used when lifting a person who is jumping or being lifted, for example a jumper in a Rugby lineout. In particular, a leg handle comprising a cylindrical section.
Description of Prior Art
There is a need to jump high in order to intercept a ball in many sports, such as Rugby, volleyball, or baseball.
For example, in Rugby Union, when a ball goes out of bounds it is returned to play using a set formation known as a lineout. In a lineout, players from both teams line up near where the ball went out of bounds. Each team forms its own line. A space of about one yard is formed between the lines of players, referred to as the tunnel. The ball is then thrown back into the playing field. The ball must be thrown straight into the middle of the tunnel. Players compete for the ball. A player has a greater likelihood of winning the ball if he is higher in the air than others. Therefore, players jump and/or are lifted up by teammates to be in a favorable position to win possession of the ball.
Other activities such as ice skating and dancing also involve lifts.
Various methods have been employed to accomplish these types of lifts and jumps.
Originally, players jumped unassisted by teammates, but the laws (rules) of Rugby Union have changed to allow teammates to support a player while in the air. At first, lifters would grab the waist of the jumper's cotton Rugby shorts. It is currently illegal to grab on to or bind to the player while the player is on the ground. As time passed, it became common to support a jumping player by grabbing the player by the bottom of the shorts and lifting him/her by the shorts long enough to play the ball. More recently, it has been made legal to grab the jumping player by the thighs above the knee. Many jumping players wrap a combination of materials and tapes around the thigh to offer those lifting a better grip.
The use of such techniques has several disadvantages such as:
It is also desirable to have a means for lifting that does not cause additional bunching and riding up of the short Rugby shorts and that looks better.
Regulation Rugby shorts are made of thick, non-stretch cotton fabric. The shorts are used to bind onto other players during play such as scrums, rucks, and mauls. The shorts are also used to lift jumpers. The legs of the Rugby short are short and wide allowing the player a large range of leg movement and reducing the surface area that may be used to disadvantageously tackle the wearer. Thus, a primary characteristic of Rugby shorts is that they are non-stretch, short-legged, and loosely fitting.
The laws of World Rugby limit the thickness of player clothing and equipment, in particular no padded equipment may be thicker than 5 millimeters.
For extra support, modesty, and comfort, it is common for Rugby players to also wear skin-tight, longer-legged, compressions shorts made of low denier stretch fabric, known as Spandex or Elastane. These separate and distinct compression shorts are worn under their regulation Rugby shorts.
On Feb. 26, 1999, Halbro Sportswear applied for a UK patent, application GB 2347067A, where strips of non-stick material are sewn into the sides and lower edges of regulation Rugby shorts. These strips of non-stick material allow teammates to more easily grip the Rugby shorts during a Rugby lineout.
Later, elastic neoprene sleeves comprising a non-slip gripping surface have been placed around legs. On Apr. 22, 2003, Mark Giarcheri filed application PCT/GB03/01719 showing a neoprene sleeve comprising a non-slip gripping surface with a ridge at the top. In 2005, KooGa introduced a “Lineout Support” comprising a neoprene sleeve with a non-slip gripping surface.
Elastic sleeves comprising other types of means for gripping have been placed around legs. For example, U.S. patent application Ser. No. 11/499,023, filed Aug. 3, 2006, and U.S. patent application Ser. No. 11/800,356, filed May 4, 2007, disclose my earlier attempts to solve these problems. While successful in part, those earlier attempts still suffer from various problems.
More recently, the Centurion brand (Primo Play Ltd.) introduced Aerial Supports™ consisting of a heavy neoprene housing a rubber lifting block. Deacon Manu developed Aerial Supports™.
Elastic leg sleeves have several disadvantages such as:
There is a need for a means to improve lifting in all levels of play, as ineffective lifts can be costly, dangerous, and contribute significantly to losing a game.
What is needed is an improved lightweight, low cost, easy to manufacture, quick, simple, easy to use, reusable, Rugby law compliant device that provides an effective means of obtaining a sure grip that offers comfort and safety to the players involved.
Further, what is needed is a device that can be used by new players and youth to safely develop their technique, skill, and timing during practices and prior to game situations that may require conventional lifting aids.
Accordingly, it is an objective of the present invention to provide an improved lightweight, low cost, easy to manufacture, quick, easy to use, simple, reusable, effective, Rugby law compliant means of lifting a jumper that provides safety, comfort, and high performance for those involved.
Accordingly, beside the objects and advantages described above, some additional objects and advantages of the present invention are:
In the drawings, closely related figures have the same number but different alphabetic suffixes.
The present invention comprises a leg handle comprising a hollow cylindrical section. When a person jumps, one or more other people can assist the jumper by gripping leg handle. Such a lifter is able to lift the jumper higher, support the jumper while in the air, and safely lower the jumper to the ground. When the jumper is not jumping, the jumper is able to run or otherwise move without hindrance or discomfort.
A first conventional means for lifting (gripping the shorts) is shown on right. The first jumper 110 is lifted by his shorts 112. The first lifter 120 lifts using both his left hand 121 and his right hand 122 on the bottom front of the shorts 112. The second lifter 130 is gripping the shorts with his left hand 131 and his right hand 132 (not shown) to lift. These grips allow the first lifter 120 and second lifter 130 to lift first jumper 110 to a height where he can intercept the ball 140.
A second conventional means for lift (gripping the thigh) is shown on the left. The fourth lifter 170 is using a similar technique of lifting as the second lifter 130 and uses both his right hand 171 and his left hand 172. Third lifter 160 is lifting second jumper 150 by his thigh 154. Note that the second jumper 150 is unstable, is falling, and was unable to intercept the ball because of the bad lift.
Lifting by the shorts has many disadvantages including, for example, discomfort for the jumper, less than optimal lift performance, and difficult to obtain grip. It is also difficult to obtain a secure grip on a bare thigh (e.g. third lifter 160), especial when the skin is covered with sweat.
The one-time-use thigh wrap also has many disadvantages including, for example, difficulty in applying consistently, requiring application by coach, trainer, or other player during the critical pre-game preparation time, discomfort, waste of materials, and debris often left behind.
Spandex stretch fabric is well known to be a woven fabric comprised of synthetic fibers known for their exceptional elasticity. Spandex fibers comprise polyurethane-polyurea copolymer strands. The elastic copolymer strands are typically combined with strands of another material, such as nylon. What gives spandex its special properties is that it has hard and soft blocks in its repeat structure.
To comply with the World Rugby law regarding clothing thickness, the combined thickness of the stretch fabric (232a, 232b, or 232c, respectively), the wall of the hollow cylindrical section of the sausage 201, and the cover 877 is five (5) millimeters or less. Others have attempted to make Rugby lifting aids but have been unsuccessful in providing a large enough grip that also complies with the World Rugby law regarding thickness. My novel hollow cylindrical section provides for a larger effective grip, while complying with the World Rugby law regarding thickness. When flattened for measurement, it is five (5) millimeters or less, but when gripped by a lifter it provides a sufficient size and shape where the radius of the outside of cylinder is substantially greater than five (5) millimeters.
Although not shown a similar arrangement of tape may be applied over each sausage (208, 209, 208a, 209a, 208b, and 209b, respectively).
In yet another embodiment of a method for use, a wrapping of stretch tape with a tacky surface is applied over the respective sausage (e.g. 209) prior to applying tape 192b and 192c.
Other Uses
While the descriptions of the various embodiments have been made in reference to Rugby Union, the present invention could also be used for other sports which involve, or in the future may involve, lifting, such as Volleyball, International Rules Football, Australian Rules Football, baseball, ice skating, dance, or other sports.
Advantages
Comfortable
The leg handles of the present invention offer comfort to the jumping player. The leg handles do not apply pressure to the sensitive crotch areas of the body, as conventional methods of lifting do. The leg handles also reduce pulling out the hairs of the leg during removal, as in certain conventional methods.
Effective
The leg handles of the present invention are effective. A lifter has much better odds for obtaining and maintaining a sure grip with the present invention than with conventional methods. Thus, the jumper is more consistently able to obtain an optimum jump.
Safe
Because of the effectiveness of the the present invention in allowing lifters to have a sure grip, the present invention offers greater safety and lessens risk of injury to both jumping and lifting players, and even opponents
Simple
The present invention is simple to make and use. The present invention requires less time to put on.
Easy to Use
The present invention is easy to use. To install, the potential jumper simply applies over one or more legs. The lifters easily can find a grip while lifting the jumper.
Unlike conventional methods of lifting, which require a second party such as a trainer or coach to apply and runs the risk of inconsistency, the present invention is easily put on and taped by one person (including the wearer) and gives consistent results.
Reusable-Reduced Waste
The present invention can be used over and over again. The conventional method of using entirely tape, most of the material can only be used once and a new material must be used for every application. With these devices and methods, most of the material is reused and much less tape is required.
Because the conventional foam wraps and tapes can only be used once, the materials become trash after use. The remains of the foam wraps and tape are often strewn on the field and leave an unsightly, unprofessional appearance requiring extra effort to clean up.
Higher Performance
The present invention offers higher performance in jumping than conventional methods. The quality of grip maintained allows stronger and higher lift, for example during a Rugby lineout. Use of the present invention gives teams more options on plays to be run during the lineout. The use of the present invention does not hinder agility or running, as conventional taping sometimes does, because the taping is much less and can be applied looser.
Quick
The present invention can be quickly applied and removed. Time from warm-up and pre-game training need not be taken to apply the leg devices. The conventional method can take several minutes to apply and removal can also be a slow process. Conventional taping often requires assistance from a coach or other highly skilled person and detracts from the critical pre-game preparation.
Adjustable
One embodiment of the present invention can easily be adjusted for different players and thus are easily switched from player to player to accommodate substitutions.
Efficient
The conventional method of taping is wasteful. Trash is created after every game, and more tape and foam wrap materials need to be replaced and bought, adding to expenses. The present invention reduces the cost and trash significantly.
Better Appearance
Conventional methods of lifting worsen the look of players. The present invention has a smooth, professional look. While conventional taping has limited options, the present invention can easily be manufactured in a variety of colors to match the team color or the individual preference of the wearer. Space on the device material may also be used to bear a team logo, national insignia, or advertising.
Cost Effective
Because the leg handles can be made relatively inexpensively, are reusable, and reduce waste, the present invention is cost effective. In particular, the leg handle can be made very inexpensively, providing a larger market and encouraging less waste.
Accordingly, the present invention provides an easy to use, simple, safe, comfortable, reusable, and effective means for lifting a jumper.
While the above descriptions contain several specifics these should not be construed as limitations on the scope of the invention, but rather as examples of some of the preferred embodiments thereof. Many other variations are possible. For example, different shapes and sizes of cylindrical sections of strap could be used. The cylindrical section could be made from a solid cylinder of foam, rubber, or similar material. Additionally, the leg devices could be made of different materials or have additional features, or be used in different sports, without departing from the scope and spirit of the novel features of the present invention.
Accordingly, the scope of the invention should be determined not by the illustrated embodiments, but by the appended claims and their legal equivalents.
