Abstract

The present invention relates to exercise equipment, particularly a device for attaching to a boxing bag. The invention consists of a strap and two adjustable arms attaching two weights. When the boxing bag is struck and spins the arms rise up and with the weights attached mimic the attack of a sparring partner. The primary advantage of the invention is that one can mimic the training of a sparring partner even when alone and have more fun and more effective training than is typically possible with only a regular bag.

Description

Boxing bag device that mimics the activity of a real sparring partner.

Field of invention: The present invention relates to exercise and training equipment. In particular, the invention relates to a novel training device that can be attached to a boxing bag, and to a boxing bag comprising the training device.

Background of the Invention: A boxing bag typically hangs from a support in an open space such as a gym and is typically used for training punches and kicks and for improving the movement of the user who engages with it. The person training with a boxing bag uses the appendages of the body to develop skills and power for improving their striking abilities, particularly in relation to combat sports. However, boxing bags are also popular among individuals striving to improve their fitness, because the response of the bag when struck provides a form of resistance that functions as an effective tool for developing strength, speed and cardiovascular performance. For others, engaging with a boxing bag is simply a source of pleasure, and possibly even an effective tool for relieving tension and stress.

Boxing bags are generally static except for their movement on a ceiling or overhead support, e.g. swinging on the end of a chain or rope. Thus, apart from their material resistance and the movement that may be afforded by the boxing bag swinging from a ceiling or overhead support, boxing bags provide little competition for those who engage with them.

By leveraging the available features of a standard boxing bag and its typical environmental set-up (e.g. its material resistance, its attachment to an overhead support via a chain or rope), the training device of the invention, when attached to a boxing bag (or as a boxing bag comprising the device), works to make physical engagement with the boxing bag a much more dynamic, competitive and fun exercise. Moreover, it allows the participant to train skills that are not typically within the purview of skills trained using a boxing bag, but are normally only possible when training with a willing partner.

A variety of devices for use with a boxing bags are available heretofore.

For example, U.S. Pat. No. 5800319 discloses a sparring device comprising a columnar member and sparring member including a belt which is attached to the columnar member (such as a dummy or boxing bag) and supports one or more horizontally disposed, forward extending, gyrating arms which strike back at a user whenever the user hits the dummy.

Another example is U.S. Pat. No. 7150700 B2 which discloses a rotating punching device that is used in combination with different types of heavy punching bags. A number of embodiments are presented, the first of which attaches to the top of a standing punching bag, using nuts and bolts, and has cushioned punching pads that revolve around the standing punching bag when struck. Another embodiment pertains to the use of the rotating punching assembly with a hanging punching bag, wherein the assembly is encircled around the hanging punching bag.

Another example is U.S. Pat. No. 4434980 which discloses a device that responds to being hit by swinging its own attached arms at its attacker. In an embodiment, a pair of boxing bags are assembled together by a rigid upper supporting structure. Arms with gloves attached hang above the bags and swing forward and upward to strike at the attacker and thus simulate an opponent fighting back.

An additional example, U.S. Pat. No. 4,564,192, discloses a training apparatus for training in the martial arts absent the presence of a sparring partner. The apparatus has a pair of simulated limbs that are designed to strike blows against the student and require the student to defend himself. The blows are directed at the user with considerable force and at a variety of different angles and positions. A spring arrangement is also part of the apparatus and resiliently biases the limb /07/2020 members towards a neutral position relative to a user positioned in a striking area.

The spring arrangement allows one limb member to recoil relative to the other limb member when a blow is delivered against the one limb member from the striking area. The spring arrangement is designed so that when the one limb 5 member recoils, it applies a resilient follow-up force to the other limb member that causes the other limb member to strike a return blow at a user in the striking area.

The above disclosures all outline apparatuses to be used in the training of martial artists and boxers, simulating to varying degrees a training partner. However, as will be made clear in the sections that follow there are a number of aspects wherein 10 the present invention either is more successful in terms of functionality relating to the effectiveness of training, or in terms of practical use to the user These include the degree to which the apparatuses can be adjusted to suit the individual user; the transportability of the apperatuses and the ease of set up in different environments, their effectiveness as to the degree to which they simulate a sparing partner or pose 15 a challenge to the user, and their ease of assembly and production.

The invention addresses a number of issues in the space of boxing and martial arts training; primary amongst them are the following.

• Those who do wish to train with a partner do not always have access to such individuals.

· Although a great many children engage in training for combat sports, such as boxing or kickboxing, it is very often the case that up until a certain age these children will not engage in sparring with a real life partner as it is deemed dangerous to their health and development. Thus, these children do not begin developing the skills that one can only learn through sparring (e.g. dealing with opponent pressure, reacting to strikes that come at full speed) until they are old enough to spar.

Statements of invention: Accordingly, there is provided, in a first embodiment of the invention, a device for use with a boxing bag, the device comprising: a strap for fastening the device to the boxing bag, the strap comprising fastening means for reversibly fastening the device to the boxing bag, and one or more arms which are anchored to the strap by anchoring means, wherein each of said one or more arms comprise one or more weights attached to said arms.

Optionally, the strap comprises first and second ends. Optionally, the fastening means is configured to reversibly connect the first end of the strap to the second end of the strap, to thereby fasten the device to the bag. Optionally, the fastening means comprises a Velcro® fastener wherein a hook portion of the Velcro® fastener is on the first end of the strap and a loop portion of the Velcro® fastener is on the second end of the strap. The Velcro® fastener allows a user to fasten the strap around the bag and quickly release the strap from the bag. Optionally, the fastening means comprises a buckle on the first end of the strap, and at least one aperture in the second end of the strap, wherein the buckle can engage with an aperture in the second end of the strap.

Optionally, the one or more weights is formed of a materials that provide for an adequate weight (such that it allows for optimum movement around the bag) and feel (such that it is not too hard to be excessively injurous, nor too soft to be unchallenging). For example, said materials maybe include an inner such as a steel bearing that might be then covered with a foam material, before being covered with a durable cloth or leater material. Optionally, the weight is connected to the arm by a connecting means. For example, said connecting means may be a steel ring that has been sown in to the fabric of the weight which is then attached to a snap hook extending from the arm. Optionally, the weight is integrally formed with the arm. Optionally, the weight is substantially spherical and is, for example, a ball. Optionally, the spherical weight is from about 1 cm — 20 cm. Optionally, the weight is shaped to resemble a boxing glove, or any other item so desired e.g. a skull, a animal head, a head in the likeness of a fighter, a personalised design, etc. Optionally, the weight is electrified to allow it to give a light shock to the user on impacting their body.

Optionally, the strap comprises a material lining that allows it to grip more firmly to the bag. Optionally, the material lining is disposed on the surface of the strap which, in use, contacts the surface of the bag. Optionally, the material lining is suitable for gripping the surface of standard bags, such as a polyvinal, canvas or leather heavy bag or teardrop bag, but also provides traction on materials employed by more contemporary training bags e.g. Aqua Bags® that employ a more plastic surface than traditional bags. Optionally, the material lining comprises a rubberised material, such as a non-slip rubber or silicone, or some composite of suitable gripping materials.

Optionally, the anchoring means for attaching an arm to the strap comprises a carabineer or a snap hook with means to accomodate webbing. Optionally, the anchoring means comprises a sliding mechanism to allow the arm to slide along part or all of the length of the strap. This arrangement allows for rapid adjustment of the arm along the length of the strap without the need for detaching and reattaching the arms. This might comprise a material sheath (e.g. a material similar to what the strap is made from) that has affixed a means for attaching a snap hook, is open at both ends, and snuggly fits the strap such that it can be simply slidden along its length. Opptionally, the means for anchoring the arm to the strap comprises a stiff rail that is fastened at either of its ends to the strap along its length, and allows for the sliding of the means (e.g. a snap hook) that attaches the arms along the length of the rail.

Optionally, the length of the one or more arms is adjustable. Optionally, the one or more arms is formed of an elastic material. The elastic material allows the length of the arm to increase, for example as a result of movement of the weight, and to decrease, for example due to the resilient nature of the elastic material.

Optionally, the one or more arms include markings to indicate the length of any arm as it includes the weights and extends from the strap, such that one can receive an immediate indication as to what the ‘reach’ of the device is in any configuration.

Optionally, the one or more arms is elasticated in proportion to the weight of the weights so as to better allow the weights to bounce around, and/or move erratically or unpredictably when in use. Optionally, the one or more arms are constructed from non-elasticated, optionally lightweight materials, such as a composite of fiberglass and graphite, bamboo, carbon etc.

In a second embodiment, the invention provides a boxing bag comprising one or more arms, wherein each of said one or more arms comprises one or more weights attached to said arm. Optionally, said one or more arms are reversibly anchored to the boxing bag by anchoring means. Optionally, the boxing bag comprises multiple anchor points for anchoring the arms to the bag. Optionally, said one or more arms is anchored to a strap. Optionally, the strap is reversibly fastened to the boxing bag. Optionally, the boxing bag comprises the device of the invention as described herein.

It will be understood that when the bag and device assemblage spins freely from a bag chain, which is typically a heavy bag chain, or when the bag-device assemblage spins even more freely when coupled with a (as part of one embodiment) means for spinning the punching bag (e.g. a swivel connector with an internal bearing), the one or more arms comprising one or more weights are caused to rise up under the centrifugal force exerted on the weights. The spinning bag with the spinning arm(s) and weight(s) then pose a challenge to the user such that the spinning bag with the spinning arm(s) and weight(s) simulates the challenge incurred from the striking appendages (e.g. arms or legs) of a sparring partner.

Optionally, the bag comprises suspension means for suspending the bag from an overhead support fixed to, for example, a ceiling or gym apparatus. Optionally, the suspensions means comprises one or more chains, ropes or straps which are tethered, optionally reversibly tethered, to the bag and tethered, optionally reversibly tethered, to the bag overhead fastening. Optionally, the overhead fastening is, for example, a hook or a hoop; or a looped chain, rope or strap that has been secured to a celing joist, an overhead girder or some other satble structure.

Optionally, the bag is attached to a ground anchor, such as a ground attached fixing or a heavy weight, optionally by means of a bearing coupled with a chain, rope or strap. Optionally, the bag is attached to a ground anchor, such as a ground attached fixing or a heavy weight, optionally by means of a resilient member, such as an elastic band, that is configured such that, when the bag is rotated, the resilient member winds up to create a tension which can be released to cause the resilient member (and bag) to rotate in the opposite direction. Optionally, the boxing bag is coupled to a groundanchor by means of a swivel connector (i.e. a connector with an internaly rotating bearing) attaching a chain, rope or strap.

Optionally, the punch bag comprises a (as part of one embodiment) means for spinning the punching bag (e.g. a swivel connector with an internal bearing) to allow for the minimally incumbered and perpetual rotation of the bag in either direction. Optionally, the means for spinning the punching bag is disposed between the bag and suspension means, or between the suspension means and the overhead support.

Optionally, an electric motor is coupled to the means for spinning the bag and drives the rotation of the bag. Optionally, the electric motor is operable to drive the electric motor at different speeds.

Optionally, the means for spinning the punching bag (e.g. a swivel connector with an internal bearing) that suspends the bag from the overhead fastening includes a means to facilitate being wound up (e.g. a swivel connector with an internal bearing and spring that can be wound) whereby the rotation of the bag can cause the means for spinning the punching bag to create a tension, which at a certain point will be released to drive the rotation of the bag back in the opposite direction, and so on having a see-saw effect.

Brief description of the drawings: The invention will be more clearly understood from the following description of an embodiment thereof, given by way of an example only, with reference to the accompanying drawings in which: Fig. la shows a birds-eye view of the device of the invention as detached from any bag, including the means for spinning the punching bag (5), the strap (1), the arms (3) and the weights (4).

Fig. 2a shows a birds-eye view of the strap (1), the arms (3) and the weights (4) when coupled with a boxing bag (2) of which its suspension means (7) are connected to a means for spinning the punching bag (5).

Fig. 2b shows a profile view of the device of the invention [the strap (1), the arms (3) the weights (4) and the means for spinning the punching bag (5)] when coupled with a boxing bag (2) and its suspension means (7) and connected to a overhead support (6).

Fig. 2c shows a 3D view of the device of the invention [the strap (1), the arms (3) the weights (4) and the means for spinning the punching bag (5)] when coupled with a boxing bag (2) and its suspension means (7) and connected to a overhead support (6).

Detailed description: The invention utilises any boxing bag that hangs from an overhead support - be that a ceiling support or some other wall or ceiling mounted fixing — and is surrounded by enough space that it will allow for proper use of the invention. Though in our example we employ a standard cylindrically-shaped boxing bag (often referred to as a ‘heavy bag’), the bag need not be shaped so, and can just as easily attach to any other boxing bag that can be suspended from overhead support.

Fig. 1 depicts an embodiment of the device of the invention detached from any boxing bag. The strap (1) wraps around and is secured to the body of a boxing bag (2) (as is demonstrated in Fig. 2), much in the same way that one wraps a belt around one’s waist; and indeed, it is similar to a normal belt insofar as it can be fastened at various lengths by a means such as a buckle and/or Velcro® and hook fastener, thus allowing for attachment to different sizes and types of bags. The strap (1) also includes anchoring means for the anchoring of arms (3) at any of a plurality of points along its length, such as apertures through which an anchoring means can be fed and secured. In one embodiment the anchoring means for attaching the arms to the strap is by way of a sliding mechanism which allows for rapid adjustment of the arms along the strap’s length, without the need for detaching and reattaching the arms. Another embodiment includes a rail that runs along the length of the strap for a short distance and is fastened to it at either of its own ends. This allows for the sliding of the means for attaching the arms within the length of the rails and thus increases the overall degrees of freedom of the invention in use. Another embodiment simply employs means such as carabineers or snap hooks with means to accommodate webbing, one side of which can be can be anchored to apertures in the belt itself, or anchoring points that have been added to the strap, such as a material hooks.

In one embodiment the strap includes a material lining that allows it to grip more firmly to the bag. This type of lining is familiar in shorts or pants that are used during sports such as golf or Brazilian Jiu Jitsu, wherein the aim is to keep the TShirt tucked indside the pants. Said lining would be disposed on the inner surface of the strap and comprised of a rubberised material, such as a non-slip rubber or silicone.

The arms (3) are typically comprised of a flexible (and/or elastic) material such as a nylon webbing and in one embodiment can be adjusted to various lengths. In one embodiment the arms are printed with markings that correspond to the length of the arms in ther present configuration, thus allowing those who engage with the invention to adjust the arms to suit their own needs, or indeed simulate the reach of a potential opponent. The arms (3) move back to front, up and down, and diagonally in all directions and are limited only when they come into contact with a bag to which they are secured, or the individual using it. In another embodiment the arms are made from less flexible materials, such as a composite of fiberglass and graphite or a carbon fibre. In another embodiment the arms themselves will be weighted such that they themselves comprise the weight without the need for an additional attachment. Such weights could themselves be adjustable by employing a telescopic function similar to a car aerial or a baton.

In embodiments wherein the arm and weight are distinct - such as in our example drawing - at the end of each arm, is a connecting means that securely attaches a weight (4) to the arm. Such means can include a steel or plastic webbing snap hook extending from the arm and hooking onto a ring or hoop sown into to material of the weight. Another embodiment might include a quick release (similar to a quick release keyring) whereby the female end of the fastener is incorporated into the weight and the male end attaches to the material of the arm by some means.

The weight (4) resembles a grain filled juggling ball in terms of its weight and resistance, though the weight can be interchanged and can be augmented to meet specific user demands, e.g. using lighter or heavier materials with more or less material resistance. Morever, the weight can be shaped to resemble a boxing glove, or any other item so desired e.g. a skull, a animal head, a head in the likeness of a fighter, a personalised design. This will add to the general personaliseability of the product. Addionally, the weight can be electrified to allow it to give a light shock to the user on impacting their body, thereby increasing the challenge and prodcuing better results by demading an adaptive response.

Materials of the various elements throughout the invention are changeable and there is no specific demand for a particular material to be used. For instance, the strap (1) might be leather, nylon webbing, or some amalgam of fabrics; the means of fixing and fastening various elements might be made of plastic or a suitable alloy; the arms (3) should be of light but strong material e.g. nylon webbing, a composite webbing, or even a light-weight though durable material like graphite, bamboo, or carbon fibre; and the weights (4) should be of a durable material and either constructed from or filled with something to add desired weight, depending of course on the end user.

In an example embodiment (as depicted in Fig. 2) wherein the invention is being used: having the invention at the ready, between the overhead support (6) and the suspension means (7) is an additional means for spinning the punching bag (e.g. a swivel connector with an internal bearing) (5), allowing the bag to rotate in an unconstrained fashion and perpetually in the same direction until stopped by an external force or by its own deceleration. The strap (1) with the arms (3) and the weights (4) is then secured around the bag (2). Once the strap is set to a desirable height, and the arms are situated properly along the strap and adjusted to the desired length, the bag-device assemblage is ready for use. Hitting the bag even slightly off center causes the bag to spin and the centrifugal force pushes the arms outwards and upwards such that they project out and strike at the user who engages with the bag.

A user can simply freestyle as (s)he engages the bag of the invention, devise any number of games to have fun, or indeed develop sparring drills that work various skills valuable to a combat sport athlete e.g., learning to get in past and out of an opponent’s reach, working on head movement and foot work, working on defending punches, experiencing the chaos and pressure of close combat, developing speed and precision, and so on.

Embodiments of this invention have the potential to addresses a number of issues when training: (a) one can mimic the training of a real partner even when alone, (b) on certain occasions it is safer than training with a real opponent, as one can adjust the weight and material of the weights to suit [this will be especially valuable to children who train in combat sports but who are not permitted to spar, or indeed who just want to have fun], (c) it turns any boxing bag into a much more interactive and challenging experience, (d) the trajectories of the arms are not easily learned, and can be endlessly adjusted due to the multiple degrees of freedom and the plurality of fixable points and adjustments, and thus it remains consistently unpredictable and challenging even with prolonged use (e) it can be adjusted to mimic the proportions of a specific opponent for training camps, due to adjustable arm length and height positioning on the bag, (f) it can be significantly more fun and entertaining than training on standard boxing bags.

When compared to previous examples of similar apperatus — as per outlined in the section ‘Background of the Invetion’ — there are numeros advantages to the present invention: « The degrees of freedom in the movement of the arms and weights and the adjustability of the present device make it a much more dynamic and consistently challenging sparring apparatus than any o f the previous inventions allow, thus better simulating the challenge of an actual sparring partner.

* Given the minimalist assembley of the present invention it will be much less inclined to damage or technical malfunctions than the inventions stated above, and moreover, as it will be relatively cheap to produce it will prove cheaper to the end consumer; • Should a user desire to keep the device of the invention within their possession, (s)he can detach the device (strap, arms, weights etc.) in less than a minute and pack it up ready for stowing away in the pocket of a typical training bag or suitcase, after which it can be reattached to any other bag and be ready for use within similar timescales. Such ease of set up and transportability is important if an individual desires to transport their own device between a home gym and a training facility or another gym; or if they were traveling and desired to bring the device with them; or indeed if they simply desired to transport the device between different bags in the same gym. The same ease of transportability and set up is not permitted in previous examples.

• The present invention provides much more adjustability to the user than previous examples, whereby it can be adjusted at the strap to fit the circumfrence of any boxing bag; adjusted according to the hight of the boxing bag to suit the user; adjusted at the arms both in terms of length (to mimic various ‘reaches’) and materials; and the weights can be adjusted in terms of weight and material resistance.

Conclusinvely, the invention can be shown to successfully address the issues that were earlier highlighted as being of primary concern for such apparatuses when training in boxing and the martial arts: • Those who wish to train with a partner do not always have access to such individuals. o Given the features of transportability, ease of set up, adjustability and the dynamic movement of the arms and weights, the present invention when coupled with a boxing bag, immediately addresses to a large degree many of the problems that this produces; turing a /07/2020 standard boxing bag from an effectively static object that a user engages with mostly offensively (e.g. throwing punches or kicks) into a responsive object that the user must engage with defensively also (e.g. blocking, dodging, and ducking), as if training with a sparring partner.

• Children who engage in combat sports, up until a certain age will not engage in sparring with a real life partner as it is deemed dangerous to their health and development. Thus, these children do not begin developing the skills that one can only learn through sparring (e.g. dealing with opponent pressure, reacting to strikes that come at full speed) until they are old enough to spar. o Given the adjustability of the materials of the present invention, with particular embodiments of the present invention whereby the weight and resistance of the materials is suited to the childs needs, the child can have fun and safely develop these skills at any age. It is forseen that this would have a significant impact on those athletes who go on to perform prefessionaly in combat sports, as early development can often be crucial to an athletes performance later in life.
