Methods and means for lifting jumper
A leg device with means for gripping, or handles, is used to aid in lifting a jumping player, especially for lineouts in Rugby Union. The simple, reusable, easy to use leg device provides a level of effectiveness, comfort, convenience, and safety not provided by conventional methods. In a leg sleeve embodiment, means for gripping include a thickened band or grip attached to a sleeve material. The means for gripping may be formed by attaching a semi-rigid material. The means for gripping may be formed by attaching extra layers in sections, in rolls, in folds. The means for gripping may be shaped to match the hand of a lifter. To use, leg sleeves are applied to the legs of a jumper. Other embodiments of leg devices include leg glove or mitt and various leg straps. An improved leg glove further comprises a non-elastic base strap. An improved leg sleeve comprises a base strap and a cross strap attached to a sleeve of stretch material. When the jumper jumps, one or more lifters grip the leg device. The lifters lift the jumper higher, support the jumper in the jump while the jumper attempts to intercept a ball, and safely lower the jumper. Non-elastic leg straps many including padding or warrior fringe.

BACKGROUND FIELD OF THE INVENTIONThis invention relates to a leg device, especially a leg device, such as a leg sleeve or leg strap, with a means for gripping used when lifting a person who is jumping or being lifted, for example a jumper in a Rugby lineout.
BACKGROUND-DESCRIPTION OF PRIOR ARTThere 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 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. 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:
-
- Being ineffective, as a good grip is often still difficult to maintain
- Being unsafe, as jumping players that are dropped because of poor grip can fall up to 10 feet and land in an awkward position
- Damage to or tearing of clothing, especially if the proper shorts are not worn
- Extreme discomfort to the jumper
- Taking time to apply during the critical stages of pre-match preparation
- Requiring help to apply, as taping one's own leg is often difficult to do satisfactorily
- Needing to be taped before every game
- Requiring special skill of the lifter in the case where only one lifter is used
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 than an awkward contraption of tapes on both thighs.
More recently, elastic sleeves with a gripping surface have also been placed around legs or knees. These also have several disadvantages such as:
-
- Being constricting during the activity between lifts
- Being too elastic and sliding up during lifts
- Being hot, causing excessive sweating and odor
- Having material break down
- Being relatively heavy
- Expensive materials requiring expensive equipment to manufacture
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 device that provides an effective means of obtaining a sure grip that offers comfort and safety to the players involved.
SUMMARY OF THE INVENTIONAccordingly, 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 means of lifting a jumper that provides safety and comfort to those involved.
OBJECTS AND ADVANTAGESAccordingly, beside the objects and advantages described above, some additional objects and advantages of the present invention are:
- 1. To provide a comfortable method of lifting a player who is jumping.
- 2. To provide a more effective method of obtaining a sure grip on the thighs of a jumping player.
- 3. To provide an increase of safety for a jumping player being lifted by the thighs.
- 4. To provide means and methods of lifting that are easy to use.
- 5. To provide means and methods of lifting that are reusable.
- 6. To provide means and methods of lifting that offer higher performance.
- 7. To provide means and methods of lifting that can be quickly applied and removed.
- 8. To provide means and methods of lifting that are adjustable to varying conditions.
- 9. To empower a less skilled lifter to lift a jumper by himself.
- 10. To provide means and methods of lifting that are minimal in cost and waste.
- 11. To provide means and methods of lifting that do not worsen a user's appearance.
- 12. To provide means and methods of lifting that do not interfere with the wearing of compression shorts.
- 13. To provide means and methods of lifting that improve a user's appearance.
- 14. To provide means of lifting that do not stretch and slide up the jumper's leg during the lift.

Special Definitions
sleeve—a substantially tubular part designed to fit over another object, such as a leg.
non-elastic strap—a substantially linearly non-elastic, flat strip or ribbon of flexible material used for securing or holding together, e.g. polypropylene or cotton webbing
elastic band—a substantially linearly elastic, flat strip of flexible material used for tightening, which has a predetermined limit to the amount of stretch before it becomes inelastic and provides tensile strength in its linear direction e.g. elastic waist band material
DESCRIPTION OF THE INVENTIONThe present invention comprises a leg device comprising a handle or other means for gripping. When a person jumps, one or more other people can assist the jumper by gripping the means for gripping. 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. Some embodiments comprise leg sleeves. Other embodiments comprise non-elastic straps comprising handles.
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).
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.
One advantage of using a flexible, elastic material is that the position of the leg sleeve may be adjusted to meet the needs of a specific condition, such as a particular play. Further, the leg sleeve can be quickly removed from one player and transferred to another player to accommodate substitutions.
When the base sleeve material 230 is neoprene, the extra layers 330 can be made of the same material to simplify manufacturing. When the base sleeve material 230 is a stretch fabric, the extra layers 330 could be neoprene or similar material.
Although shown at the top, a leg sleeve 200 could have multiple thickened areas at the top, middle, and bottom of the sleeve material 230.
Although shown rolled at the top, the roll 350 also could be formed somewhere in the middle of the sleeve material 230 by pinching the material in the middle and rolling the resulting fold. The roll 350 could be then be held by the attachment 220.
Further, a leg sleeve 200 could have multiple rolls 350 at the top, middle, and bottom of the sleeve material 230.
Prior to entering the game, each potential jumper (e.g. first jumper 110 and second jumper 150) applies one or more leg sleeves 200 of the present invention to one or more legs. When an opportunity to intercept the ball occurs, each jumper jumps. One or more players from the jumper's team are then able to grip the leg sleeves 200. For example, as shown in
Because the respective lifters can obtain a safe and secure grip on the leg sleeves 200 of their respective jumper, both jumpers are able to: a) achieve a higher performance jump, b) be held stable during the jump, c) have a more consistent, more competitive attempt for the ball 140. The lifters are able to get a more consistent grip on the jumper. The jumper is able to jump with and be supported with less discomfort and more safety and confidence.
Compare the height and stability of the jumpers in
The increased safety and performance of various embodiments of the present invention may allow for changes in the Laws (rules) of Rugby to allow lifters to support jumpers using the various embodiments.
Further, while the leg sleeves 200 of the present invention are shown as applied to Rugby, the leg sleeves, or other leg devices of the present invention, could be used in other sports that also require jumping, such as Volleyball (e.g. while spiking a set ball, etc.) or Baseball (while jumping at the fence to stop a home run, etc.).
For example, in Rugby, because it is not legal to bind with the jumper before the jump is started, the lifters must assess a location to grip while the jumper is in the air. Thus, using the present invention, it is easier to place the open hands against the leg sleeves 200 until the palms of the hands rest against the shaped grips 550. In this way the lifter can quickly assess the location of at least one of the means for gripping 210 and immediately apply lifting pressure against the means for gripping 210.
Because of the immediate, sure grip provided by the memory foam 560, the lifter does not have to spend time assessing the location of the means for gripping 210. In Rugby, because it is not legal to bind with the jumper before the jump is started, with this embodiment, the lifter may place the open hands against the leg sleeves 200 making an immediate impression. In this way the lifter can immediately apply lifting pressure against the means for gripping 210.
This embodiment provides a means for a single, relatively unskilled lifter to assist a jumper. For example, the single lifter can stand behind the jumper in a lineout. When the jumper jumps, the lifter is able to place his hands on the back of each leg sleeve 200 below the back grip 580. The jumper temporarily sits on the uplifted hands of the lifter. The back grip 580 prevents the lifters hands from sliding up the legs of the jumper. Having a single lifter allows for more offensive players to be distributed across the field and, under the rules of Rugby, reduces the number of defenders who can be close to the lineout.
This embodiment can also be used with two lifters, where a lifter's hand is placed on the back of the leg sleeve 200 against the back grip 580 and another hand is placed on the front of the leg sleeve 200 against the front grip 590 to provide a safe, secure, high performance lift.
As shown in
The layout shown in
The leg glove 700 (or leg mitt) embodiments provide improved, more secure grip. The hand (shown as 122) is easily slipped inside the pocket 750 during the lift and is easily removed as the jumper comes down. The downward facing pocket opening is less likely to engage the hands or fingers of other players at other times, for example, while being tackled during open play.
As shown in
Each of the straps is made of a non-elastic, flat strip or ribbon of flexible material. The base strap 810 is of a fixed circumference such that the leg device can be passed over the calf 994 and knee 992 but stopped securely when it reaches the larger circumference of the lower thigh 990 (see, for example,
The cross strap 820 is shown at a diagonal with an attached portion 825 and an open portion. As shown in the cross section of the front wall in
During the lift, the cross strap 820 could have over one hundred pounds of force applied to it. To prevent the base layer 740 material from tearing, and to more evenly distribute the force to the base strap 810 (and then the jumper's leg), the reinforcement strap 830 is attached between the base strap 810 and a cross strap 820 forming a triangle. This provides the V-shape which, as discussed above is designed to match the shape and location of the hand (e.g. 122 as shown in
The layout shown in
The straps with sleeve 800 embodiment provides an improved, more secure grip. The hand (shown as 122) is easily graphs the open portion of the cross strap 820 during the lift and is easily released as the jumper comes down.
The novel, non-elastic base strap 810 overcomes a disadvantage found with conventional leg sleeves that, because they are elastic, continue to stretch during the lift and slide up the leg. Further, the use of smaller circumference sleeves only partially addresses this problem and adds to the discomfort and constriction of leg sleeve between lifts.
Further, by attaching the straps to the base layer 740, it is more difficult for the opponents to use the strap system disadvantageously.
The leg strap 900 is adjustable to fit a wide variety of leg sizes. This results in several advantages over other leg devices. The manufacture needs to make only one size. The distribution channels need to stock only one size. The user can easily order the right size and the same leg device can be shared by multiple players.
The novel structure allows the leg strap 900 to rapidly and easily attached over the thigh 154, without having to bend over to slide it over the foot, shoe, and calf. For example, the leg strap 900 could be carried in the jumper's pocket between jumps and quickly put only just before a jump. Alternatively, the leg strap could be thrown in from the sideline, exchanged by players on a substitution.
The free end of the handle 980 has a handle stop 930. As shown in detail in
Referring back to
Also as shown in
As shown in
Referring back to
The ability to stow the handle 980 (and to flatten the handle stop 930) provides the advantage that between jumps the jumper can loosen the leg strap 901 and stow the handle 980 in a position (for example, on the front of the leg) where it would be difficult for the opposition to use, for example, to gain an advantage on a tackle.
Referring back to
The handles (880 or 980) are easily grasped before or during each jump or lift, and are easily released after the lift. Between lifts the handles 980 may be stowed. Whether stowed or not, the handles 980 are less likely to be used by opponents than straps with permanent open portions.
If a jumper desires additional cushion, comfort can increased by added a padding strip 970. As shown in
Alternatively, a strip of material with novel warrior fringe 972 (
Alternatively, in an alternate embodiment (not shown), the warrior fringe 972 comprises a plurality of fringe elements each independently attached (for example with hook and loop fasteners) to the strap (810 or 910). Each fringe element could appear as a decoy handle. An opponent attempting to tackle by pulling the handle 980, more often than not would be disappointed with a handful of fringe elements, instead of a tackle.
The embodiment provides the advantage that the leg straps (900 or 901) are always in the proper location on the leg and they can be fully loosened between lifts. The attached shorts are worn, for example, under normal Rugby shorts, the loosened handle will not generally be reachable by a would-be tackler, but would be readily available to a lifter from the jumper's team. The optional handle stops 930 (shown) advantageously stop the straps 901 from unplanned detachment from the bite loops 920 (a-b) or belt loops 971.
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.
ADVANTAGESComfortable
The leg devices of the present invention offer comfort to the jumping player. The leg sleeve, leg glove, and leg straps do not apply pressure to the sensitive crotch areas of the body, as conventional methods of lifting do. The wearer also does not risk pulling out the hairs of the leg during removal, as in certain conventional methods.
Effective
The leg devices 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 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. Some embodiments also provide increased safety for other players, such as opponents.
Simple
The present invention is simple to make and use. The present invention requires little time to put on.
Easy to Use
The present invention is easy to use. To install, the potential jumper simply applies, or pulls over, one leg device over each leg. 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 by one person and gives consistent results.
Reusable
The present invention can be used over and over again. The conventional method of wraps and tapes can only be used once and a new one must be used for every game.
Because the conventional wraps and tapes can only be used once, the materials become trash after use. The remains of the 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.
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 of taping 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
The present invention can easily be adjusted to different heights and positions on the leg. This easy adjustment enables the devices to be set to accommodate different lifters and/or different plays. The present invention can easily be switched from player to player to accommodate substitutions.
Empowering
The present invention can empower a single player to lift jumper when that player would not be able to otherwise do so. This can offer teams a considerable advantage in the lineout as well as the reception of kicks.
Efficient
The conventional method of taping is wasteful. Garbage is created after every game, and more taping and wrap materials need to be replaced and bought, adding to expenses. The present invention does not produce additional garbage or cost on repeated uses.
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.
The warrior fringe improves the user's appearance and helps promote the spirit of the competition.
Can be Used with Compression Shorts
Some players elect to wear compression shorts while playing their sport. Conventional methods of taping are ineffective when used with compression shorts. The present invention enables players to wear compression shorts and in combination with means for lifting.
Cost Effective
Because the leg devices can be made relatively inexpensively, are reusable, and eliminate waste the present invention is cost effective. In particular, the leg strap embodiments can be made very inexpensively, providing a larger market and encouraging less waste.
CONCLUSION, RAMIFICATION, AND SCOPEAccordingly, 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 widths of strap could be used. 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.
