Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS REFERENCE TO RELATED APPLICATIONS [0001]This application claims priority benefit of Provisional Patent Application 60/745,365 filed Apr. 21, 2006 BACKGROUND OF THE INVENTION [0002]In the field of martial arts, many devices have been employed to allow the individual adherent to practice and perfect the execution and delivery of combative strikes. Equipment, familiar to most practitioners of the art, are the suspended heavy bags, of leather, canvas or the like, configured in form, much like a dufflebag stuffed with sawdust, sand, rags, foam or other packing material. [0003]These heavy bags come in various dimensions of length and girth, and in weights, most frequently between 50 and 100 pounds. Not withstanding their long use, they and other strike training equipment possess limitations that will be both addressed and remedied by this disclosure. Most important to note are that these striking bags and other strike training tools are not capable of providing a variable, and selectively pre-determined resistance at point of impact. Attempts to effect a change in the resistance at the point of strike, with heavy bags as an example, has run the gamut from having a plurality of different weighted bags, attaching weights or bungee cords to the bottom, and having people of various statures assist in steadying the bag to provide greater resistance to strikes and limit the movement of the bag on impact. [0004]Most training facilities serve multiple users. As people are endless in variations of height, weight class, strength, skill level, etc., prior art may be suitable for only one user or a small number of users, or for one form of strike, practice or execution. Therefore, with present means it is possible, that a student may be either under or over challenged during any practice session. [0005]Centuries ago, the Japanese devised a training system to increase striking power known as the makiwara. Essentially, the makiwara was a planed down and tapered length of lumber, normally of oak, poplar or ash, driven into the ground with about 4-5 feet extending above the surface. A striking pad was affixed toward the top of this exposed portion of the board and the student could practice both hand and foot, arm and leg strikes targeting this pad. The most important advantage of the makiwara is that it provided a spring like resistance when struck and as a punch, for example, hit the pad, resistance at the surface point of impact actually increased through the linear travel of the strike. This is the opposite in dynamics when striking a heavy bag or the like where the bag moves and/or absorbs the impact of strikes. When martial arts students were provided with multiple makiwara of various strengths in these training facilities, a progressive resistance program for strike training was attained. This resulted in the predictable development of a substantial increase in striking power. [0006]The described training using multiple makiwara of various strengths, having the stated spring like feel and stated unique striking dynamic, served to increase striking power in much the same manner as progressive resistance weight training is known to increase muscle size, strength and lifting performance. This multiple makiwara training using various strength resistance and lengths, facilitated students in developing power, focus and effectiveness in striking different size opponents and in developing power using different parts of the body as strike weapons. [0007]Modern versions of the makiwara are actually less effective and most are poorly constructed. Limited by the fact few people can now opt to train outside, bracket means are used to hold mostly inadequate 2.times.4 home center purchased lumber. The modern versions now being used indoors are mostly non-production home made equipment of poor or inconsistent quality, ineffective in design and "seat of the pants" engineered. Most important, with either the centuries old original or the modern configured versions, resistance cannot be adjusted for different ages, sizes and striking ability of students. Traditional training with a multiplicity of makiwara, although effective, has not adequately bridged the gap for use in modern boxing and martial arts gyms. [0008]What has long been needed is a piece of strike training equipment possessing the following characteristics: capable of either portability or stationary attachment to the floor or wall; as appropriate to the environments of home or professional facility use; an adjustable makiwara spring like feel at the point of contact, comparable to the original makiwara; easily and infinitely adjustable, to enable users to practice various strikes at different and selectable resistance levels, and being able to take advantage of progressive resistance to develop power and focus. Additionally, such a long needed piece of equipment should be able to be configured with not only the small focus pad of the traditional makiwara, but also be capable of fabrication in a scaled up version with a larger striking pad target, allowing those training with the device to benefit using stated progressive resistance training with strike combinations. [0009]Prior means used to overcome the aforementioned deficiencies have fallen short in key ways and it is an object of this invention to put forth remedy and to disclose novel means to further the art and correct such noted shortcomings. [0010]For example U.S. Pat. No. 5,665,035 by Tumminia, discloses a corner only striking tool of a somewhat makiwara configuration. However, the striking pad is braced and negates a flexibility and particularly, the possibility of adjusting tension to match technique or user. Tumminia basically defines a platform for mounting various attachments and does not address adjusting for variable tension/resistance in a strike training tool. [0011]U.S. Pat. No. 5,984,842 by Chu, discloses means to provide for some tension and rebound in a striking tool, however, fails to provide for progressive resistance training and is overly complex. Additionally, the multi axis design is contrary to the objective of this disclosure and likewise does not adjust and return into battery with a rebound delimiter, and therefore, does not result in quick return to the "start/at ready" position. [0012]U.S. Pat. No. 4,093,212 by Jacques does provide for a modicum of progressive adjustment, but uses a weak single expansion spring that can be hand stretched to engage at different affixing hole locations, lacks an infinity of adjustment and is designed for only uppercut training. [0013]U.S. Pat. No. 4,836,533 by Dong offers a makiwara like appearance but comprises a piston to effect resistance, however, hydraulic and or pneumatic adjusting means does not offer the duplication of the desired spring like feel, quick adjustment or rapid return into the "at ready/start" position. SUMMARY OF THE INVENTION [0014]What has long been needed is a strike training tool for the martial arts, boxing and the like that is infinitely adjustable as to the resistance at the point of impact, intuitive to use and suitable for either focus or combination strike training. Likewise, said strike training tool should have the ability to provide challenging training sessions to all skill levels of users and be suitable for perfecting the execution and form of numerous power and follow-up strikes. Said means should be simple, intuitive, durable, easy and economical to manufacture, transport and assemble. [0015]This invention discloses such means comprising a base member enable the inventive device to be a stand alone unit, attached to the floor or movable, with or without a deck for the user to stand on; or attachable to a wall or pillar mount fixture; a pivotal mast that is pivotally attached to said base member; a tension anchoring assembly having a braced upright member, designed to add, remove, compress, expand or reposition springs, bands or the like in order to increase or decrease resistance at the point of striking impact. [0016]The features of this invention and the preferred embodiments that illustrate both expansion and compression means to provide variable resistance at the striking pad surface, will become clearer by reference to the following drawings and descriptions. Unless otherwise noted, for the sake of clarity and for conceptual purposes, with the exception of the striking pad, bumper, springs and spring position fixtures, all parts should be considered fabricated of steel tubing or the like. While steel tubing is preferred over other materials, for simplicity, strength, economy and ease of manufacture, obviously other materials can be used.
