Patent Application
20130185852
This invention relates to protective apparel for use in martial arts or fitness training. In particular, it relates to protective apparel adapted to be worn by a user during martial arts training exercises involving contact between two participants, such as pad work or spar training. The term “spar training” is used broadly herein to refer to any martial arts training exercise involving contact between two participants, and thus includes pad work within its scope.
Spar training, often referred to simply as sparring, is an essential part of martial arts training utilised in practically all forms of martial art. It allows a trainee to practice and develop their skills against an actual opponent, though in a strictly regulated environment, rather than against a static, artificial opponent such as a dummy or punch-bag. In addition to its use in martial arts, spar training has also gained popularity in general fitness training.
Clearly, the protection of participants against injury is of great importance in any spar training encounter. A wide range of protective apparel has been developed, which varies in construction according to the part of the body to be protected, and the form of martial art for which it is intended. The aim of such protective apparel is to attenuate the impact of strikes (punches, kicks etc.) received from one's spar training partner, and this is generally achieved by the use of some form of compressible foam.
Compressible foam protective apparel does however suffer from a number of drawbacks. In particular, the presence of a solid medium—whatever its shock-absorbing properties—in contact with the user's body, means that some force from the impact will still be transferred to the user. The risk of injury can thus only be reduced rather than eliminated. For the same reason, the risk of injury to the hand or foot of the spar training partner performing a strike also remains. Additionally, the wear and tear caused by repeated striking will eventually take its toll on the apparel, resulting either in the compressible foam becoming fatigued (i.e. failing to expand back to its initial state following impact) or the apparel becoming damaged. Either of these occurrences will expose the user to the risk of potentially serious injury. This problem can be compounded by the fact that the apparel may show no visible signs of having failed.
In addition to the risk of injury associated with such unsatisfactory protection, the quality and efficacy of spar training can also be adversely affected. That is to say, because of the known shortcomings of compressible foam protective apparel as outlined above, users tend to limit the power which they impart to strikes, so as to avoid injuring themselves or their partner.
The applicant's co-pending UK patent application no. 10 16826.8 discloses inflatable martial arts training apparatus intended to be removably mounted on a structural element within a building, for the performance of martial arts or fitness training exercises involving a user punching and/or kicking the apparatus.
It has now been realised that sufficient pressure within such an inflatable bladder can withstand even the extreme forces associated with being punched or kicked by a martial arts master. Moreover, the shock-attenuating properties provided by an inflated bladder have been found to be superior to those associated with compressible foam. The present invention thus seeks to provide inflatable personal protection for use in spar training which overcomes the shortcomings of compressible foam protective apparel, and provides increased protection against injury, whilst enabling users to impart full power to their strikes during spar training. The present invention further seeks to provide a lightweight, easily portable and collapsible alternative to conventional protective apparel.
The present invention has been developed for use in martial arts spar training, and will therefore be described herein with particular emphasis on this intended use. Nevertheless, it is envisaged that the present invention may also be adapted for use in relation to other contact sports, or indeed for use in any environment where protective apparel is desirable.
According to the present invention there is provided protective apparel for use in martial arts or fitness training, comprising:
The inflatable bladder may be inflated either prior to the user donning the protective apparel, or once the apparel is in situ on the user's body. It is however essential that inflation of the bladder to the required pressure be carried out prior to the commencement of spar training. Inflation of the bladder may be carried out either orally, using conventional air pumps, or by the provision of canisters of pressurised air or other gas.
The strike surface is preferably three-dimensional, and most preferably has a generally cylindrical profile. This is preferably achieved by forming the inflatable bladder such that it adopts a generally cylindrical profile on inflation.
The inflatable bladder preferably comprises one or more strengthening ribs, located internally thereof. The strengthening ribs serve to impart greater resistance against damage and so prolong the useful life of the protective apparel. Most preferably, said strengthening ribs divide the inflatable bladder into a plurality of chambers, thereby imparting a segmented structure to the apparel. This segmented structure also assists in providing the generally cylindrical profile.
The protective apparel may be formed with each said chamber being individually sealed, which would necessitate each individual chamber being provided with its own inflation valve. However, it is generally preferred that each said chamber will in fact be in fluid communication with its adjacent chamber(s), such that air may flow from one chamber to another, with the inflatable bladder being provided with a single inflation valve. This enables the bladder to be inflated to a higher pressure than would otherwise be attainable, thus giving enhanced protection. Moreover, allowing air to flow from one chamber to another has been found to enhance the shock-attenuating properties of the inflated bladder, by means of a process known as pneumatic energy dissipation (PED).
Two or more inflatable bladders, each having an inflation valve associated therewith, maybe provided. Each inflatable bladder may comprise a plurality of interconnected segmented chambers.
The protective apparel, and the inflatable bladder which forms an integral component thereof, are preferably formed from thermoplastic polyurethane (TPU) and/or polyvinyl chloride (PVC). This may desirably take the form of TPU or PVC coated fabric material. The seams and joints of the apparel are preferably joined by ultrasonic welding, in order to provide maximum strength without the need for additional components or materials to achieve the joining.
In order to protect the or each inflation valve, each said valve is preferably located on a surface other than the strike surface. The or each inflation valve is preferably a quick release valve to facilitate speedy deflation of the device following a training session.
The securing means to enable the protective apparel to be worn by a user preferably comprises one or more straps. Most preferably, said one or more straps are provided with complementary quick release buckle fasteners.
In a first major embodiment of protective apparel according to the present invention, the apparel is adapted to be worn on a user's torso, and comprises: a generally cylindrical central portion adapted to wrap around said user's torso such that the strike surface extends over the front thereof; an upper portion adapted to protect said user's chest region; and a lower portion adapted to protect said user's groin region; each of said upper and lower portions extending from the generally cylindrical central portion.
The strike surface preferably extends over said generally cylindrical central portion and said upper and lower portions. The inflatable bladder preferably extends throughout said generally cylindrical central portion and said upper and lower portions.
In said first major embodiment, the securing means preferably comprises a pair of parallel straps adapted to be secured across a user's back region. Alternatively, or additionally, the securing means may comprise a pair of parallel straps adapted to be secured over a user's shoulder region.
In a second major embodiment of protective apparel according to the present invention, the protective apparel is adapted to be worn on a user's leg or arm, and is adapted to wrap around said user's leg or arm such that the strike surface extends outwardly thereof.
In said second major embodiment, the securing means preferably comprises one or more straps adapted to be secured over an inner face of said leg or arm.
It is envisaged that said first and second major embodiments may be utilised together, so as to increase the area of the strike surface and thus provide protection to the user over a greater area of the body. Accordingly, the present invention also provides a protective apparel kit comprising an article of protective apparel for a user's torso as hereinbefore described, and one or more articles of protective apparel for a user's leg(s) and/or arm(s), as hereinbefore described.
In order that the present invention may be more clearly understood, a preferred embodiment thereof will now be described in detail, though only by way of example, with reference to the accompanying drawings, in which:

The torso protector 10 is formed with a generally cylindrical central portion 15, intended to wrap around and protect the torso of a user. At the front 16 of the protector 10, are formed upper and lower portions 17, 18 extending from the central portion 15. The upper portion 17 is intended to cover and protect a user's chest region, whilst the lower portion 18 is intended to cover and protect a user's groin region. The strike surface 11 extends over the central portion 15, the upper portion 17 and the lower portion 18. The inflatable bladder 12 extends internally of the protector 10 throughout the central portion 15, the upper portion 17 and the lower portion 18.
