Definitions

  • This invention relates to hand exercisers and more particularly to exerciser devices for use in strengthening and therapy of the muscles of the forearm, wrist, hand and fingers.
  • Hand exercise units herein generally termed hand exercisers, are well known devices employed in the exercising of the muscles.
  • the muscles are brought into operation in the forearm, hand, wrist and fingers as a result of contraction of the hand against the resistance of the hand exercise unit.
  • This resistance is generally offered by steel elements under tension, such as springs, or by rubber balls to be gripped by the hand.
  • These devices are intended to accommodate the hand but are generally limited to a single range of movement as the devices are forced to contract. This limited range of movement accordingly limits the benefit that can be achieved in carrying out exercises using such exercisers.
  • U.S. patent 4,750,734 to Greenfield discloses a hand exerciser that provides for a wide variety of neuromuscular responses in physiotherapy and muscle building in a single device.
  • the Greenfield patent further discloses that different resistance levels can be experienced within the hand exerciser depending on the location of the apertures with respect to the ring.
  • the varying degree of resistance is limited due to the uniform nature of the material used to form the hand exerciser.
  • the Greenfield patent also discloses that different resistances can be applied to different sectors on the web. However, this is achieved by using an external frame with adjustable tensioning devices.
  • the present invention addresses these issues by creating a hand exerciser made from multiple materials wherein each material consists of a different elasticity modulus. Therefore, a wide range of resistance levels can be provided for with a single hand exerciser without the need for an external force to vary the resistance of the web.
  • an exercise apparatus includes a rigid frame, a resiliently deformable web tensioned to the frame, the web being comprised of an array of apertures sized to accommodate human fingers, wherein the web has at least a first portion and at least a second portion, wherein the first and the portions are made of materials with different resistance levels.
  • the web has multiple portions, wherein each portion is made of different material, with a different resistance level.
  • the web is molded around the frame.
  • the apertures on the at least a first portion are a different shape than the apertures on the at least a second portion, and the different shapes have different resistance levels.
  • the web has multiple portions, wherein each portion's apertures are a different shape than the apertures on the other portions.
  • a method for exercising includes the steps of providing a web with at least a first portion and at least a second portion, wherein the first and second portions are made of materials with different resistance levels, molding the web onto a substantially rigid frame, inserting associated fingers into the apertures, pulling the web toward an associated body, and releasing the tension on the web.
  • providing a web with at least a first portion and at least a second portion, wherein the first and second portions are made of materials with different resistance levels further includes the step of providing a web with multiple portions, wherein the portions are made of materials with different resistance levels.
  • providing a web with at least a first portion and at least a second portion, wherein the first and second portions are made of materials with different resistance levels further includes the step of providing a web with at least a first portion and at least a second portion, wherein the apertures of the first and second portions are different shapes with different resistance levels.
  • providing a web with at least a first portion and at least a second portion, wherein the apertures of the first and second portions are different shapes with different resistance levels further includes the step of providing a web with multiple portions, wherein the apertures of the portions are different shapes with different resistance levels.
  • a hand exerciser for multi-movement exercising of the muscles of the forearm, hand, wrist and fingers, which comprises a rigid frame spanned by a resiliently deformable web held under tension and formed with an array of apertures sized to accommodate the human fingers, the web material being an elastomer having elasticity and hardness properties which render it capable of offering variable resistance to deformation according to the positions of fingers inserted in the apertures.
  • the material from which the web is produced will generally be a thermoplastic rubber or elastic plastics elastomer.
  • Such material preferably has a Shorr A hardness of 20 degrees to 80 degrees, an elasticity modulus from 1 to 10 MN/m 2 , a tensile strength from 7 to 35 MN/m 2 and an elongation at break of 100% to 1000%.
  • the Shorr A hardness ranges from 40 to 60 and the tensile strength ranges from 10 to 30 MN/m 2 .
  • a typical such material is the product MA198 from BTR Limited.
  • the web may be of sheet form with openings stamped or otherwise formed therein or may be a mesh formed of strands of material as aforesaid crossing over at regular intervals and interconnected at the crossover positions.
  • the web may be made from a wide variety of materials that meet the requirement of being resilient. In general these include elastomeric materials whether vulcanized or unvulcanized, cross-linked or non-cross-linked or containing a cross-linked or partially cross-linked component.
  • vulcanized is used to imply the use of heat and possibly pressure in forming a three-dimensional molecular network, while cross-linking covers the formation of a three-dimensional molecular network at any temperature.
  • the composition utilized to produce the web having physical characteristics as aforesaid may contain the usual additives for providing protection against water, ozone and weathering, reinforcing fillers, inert fillers, colorants, anti-abrasion agents etc.
  • the present invention is formed by molding the web around a rigid frame whereby the molding composition becomes disposed and cured. This is a particularly suitable procedure when the web is of sheet form, such a form of exerciser being relatively inexpensive to produce and nevertheless capable of permitting a wide variety of muscle movement according to direction of stressing, thickness of web and percentage area of cells in the vicinity of the cells through which the fingers are placed.
  • the preferred embodiment is shown in FIGURES 1 and 2.
  • the hand exerciser is formed as an integral molding comprising a sheet 10 of a rubber composition molded over and between a circular ring 11 and formed with an array of apertures 12 each sized to receive a finger or thumb.
  • the molded rubber inside the ring 11 that contains the apertures 12 is referred to as the web 13.
  • the web 13 can be made from multiple materials wherein each material has a different elasticity modulus.
  • one half of the web can be made of a material that has an elasticity modulus 3 MN/m 2 and a second material that has an elasticity modulus of 6 MN/m 2 .
  • each half of the hand exerciser will have a different resistance level. This allows the person using the device the ability to realize a wide variety of resistance levels than would be permitted in a hand exerciser made from one material.
  • the number of different materials used to make the web on a single exerciser is not limited to two and can be any number of materials chosen with sound engineering judgment.
  • FIGURE 1 shows the preferred embodiment with circular shaped apertures 12.
  • the aperture shape also contributes to the exercise features of the present invention.
  • the apertures may be square 14 as shown in FIGURE 4 or triangular (not shown), rectangular (not shown), hexagonal (not shown) or any geometric shape chosen with sound engineering judgment.
  • a portion of the apertures can be of one shape and another portion of the apertures can be of a different shape.
  • the amount of resistance will depend on the size and shape of the aperture in relation to the size of the user's fingers. A tighter fit will result in a greater resistance than will a loose fit.
  • the fingers are inserted into the apertures 12.
  • appropriate muscle groups are employed to overcome this resistance.
  • twisting, pulling, pushing movements may be applied to the hand exerciser.
  • one or more fingers it is possible to contract the web 13 in various ways in carrying out scissor movements, curling and related motions.
  • more than one individual may use the device simultaneously wherein each person places their fingers into the cells in one area of the grid and then applying tension in opposite directions.
  • the hand exerciser of the invention is a useful accessory for sufferers of arthritis and rheumatism and may be used in physiotherapy in hospitals. It may also be used in exercising or training by persons whose sporting activities require the use of the hand and forearms, wrist and fingers and is expected to be of special benefit to persons who play golf, cricket, tennis, judo, gymnastics, baseball, swimming, skiing, wind surfing and mountaineering. It is conservatively estimated that over twenty exercises can be performed efficiently with the hand exercisers of the invention, as well as approximately thirty physiotherapy-training principles.
