Definitions

  • CT A fingertraining apparatus comprising a grip portion ⁇ 2? ⁇ K531111111::11:1::111111111111111111111185132583 and a forked Portion formed/n with the [581 Field of Search 272/67 68 57 D' grip
  • the fmked Spaced arms which support a couple of uxtaposed rollers rotatable therebetween.
  • the present invention relates to an apparatus for training the humanfingers, and more particularly, relates to finger-training apparatus of the type which is handy to be carried out and is usable readily by the user for the purpose of training his fingers.
  • a portable finger-training apparatus as disclosed in his Japanese Patent No. 233915.
  • This apparatus comprises. a grip portion and a forked roller-supporting portion formed in connection with said grip portion, a sole roller being rotatably supported between two arms formed on the roller supporting portion. It is intended in use that one who wishes to train his fingers takes hold of the grip portion with only one of his fingers to'be trained, the foregfinger for example, being applied to the roller surface, and practices the training step by repeatedly bending and stretching it in a rhythmical manner, with the finger being kept in engagement with the roller. With this structure, however, it is not possible to effect a simultaneous training.
  • the present invention has one object to provide a portable finger-training apparatus of the type which enables a simultaneous training for the thumb and any one of other four fingers.
  • Another object of the invention is to provide a portable finger-training apparatus which enables a training only for any desired one of the human fingers in addition to the above training.
  • the finger-training apparatus comprises a forked roller-supporting portion on which two juxtaposed rollers are rotatably mounted, the rollers having respective tooth for meshing engagement with each other in such a manner that when one roller rotates in a certain direction, the other is caused to rotate in the opposite direction.
  • FIG. 1 is a side elevational view of a finger-training I apparatus according to the present invention
  • FIG. 2 is a sectional view taken along the line "-11 of "FIG. '1;
  • FIG. 3 is a bottom view of the finger-training apparatus shown in FIG. 1;
  • FIG. 4 is a top view of the finger-training apparatus shown in FIG. 1;
  • FIG. 5 is a schematic view illustrating how the user practices the apparatus with his right hand for a simultaneous training of the thumb, forefinger and middle finger;
  • FIG. 6 is another schematic view similar to FIG. 5 however illustrating how the user performs a simultaneous training of the middle finger, ring finger and little finger of his right hand.
  • finger-training apparatus comprises a grip portion 10
  • the forked roller-supporting portion 11 has twospaced arms 12, 12a which extend downwardly, as viewed in FIG. 1, with one in front and the other in the rear, and these arms carry a couple of shafts l3, l3 juxtaposed therebetween.
  • One end of each shaft 13 is in shrinkage fit in a blind hole 14 formed on the rear arm 12a while the other end being also in shrinkage fit in a through-hole 15 on the front arm 12.
  • the head 16 of each shaft 13 is in engagement with the outer surface of the front arm 12.
  • a roller 17 is rotatably mounted on each shaft 13.
  • it may alternatively be arranged that by providing journals at both ends of each roller 17, the rollers be in loose fit in respective blind holes formed on the inner sides of the front and rear arms 12, 12a.
  • This alternative arrangement eliminates the provision of the above described shafts 13.
  • the rollers 17 have respective spur gears 18 at their front ends for meshing engagement with each other, so that synchronous rotation of the paired rollers 17 be attainable to facilitate a simultaneous training of fingers reducing risks of uneveness in the training effect.
  • there is no provision of such meshing gears on the rollers there is no provision of such meshing gears on the rollers, however the effect of finger training achieved in this case might be lessened to some extent.
  • Each roller 17 is in the shape of a bulge or is diametrically enlarged of its middle, and provides therearound a plurality of substantially longitudinally extending grooves 19 in rows (See FIG. 2), which serve to facilitate engagement of the fingertips with the rollers during use of the apparatus, as will be described hereinafter.
  • the configuration of the roller is not necessarily limited to that illustrated herein, but may be cylindrical for example.
  • the grooves 19 on each roller extend somewhat twistingly of the roller axis, which also facilitates the effect of engagement between the fingertips and the rollers. Any suitable angle of twisting can be provided as desired. Further, alternatively, each roller may be provided with a plurality of properly spaced projections therearound, in place of the described grooves 19.
  • the shafts 13 are placed both in a common plane with their axes extending oblique to each other in a convergent angle indicated at D.
  • the degree of this angle D may be predetermined properly depending on the desirous conditions of engagement between the fingertips and the rollers.
  • the gears 18 are shown as mounted at the front ends of the associated rollers 17, however they may alternatively be mounted at the rear ends of the rollers.
  • the additional provision of not shown means for releasing the gears from mesh engagement, conveniently enables the training exercise of a sole finger through one roller only.
  • the finger-training apparatus according to the present invention is shown as being ready for operation with the grip portion 10 grasped between the third finger, little finger and the hollow of the users right hand, and with the grooves 19 of the rollers 17 being engaged by the tips of the thumb and the forefinger, middle finger, respectively. From this starting position, repeated motion of simultaneously bending and stretching the thumb, forefinger and middle finger altogether is effected while keeping all the fingers in engagement with the respective rollers. This motion exercise is best suitable to the training of handwriting.
  • Each roller 17 may be properly determined of its weight depending on the specified purpose of training or the convenience of handling by the user. In this connection, it will be more advantageous to design the apparatus such that the rollers are detachable from the roller supporting portion.
  • the finger-training apparatus may be made of any suitable material, it is preferred that the shafts for supporting rotatable rollers be metal made and other parts be all made of plastics.
  • present finger-training apparatus may be used not only in manners shown by FIGS. 5 and 6, but also may be used in other varied manners.
  • a finger-training apparatus comprising a grip portion shaped to be held by one hand of a human, a forked roller supporting portion including two spaced arms, two rollers positioned between said spaced arms and rotatably journalled thereto, means connecting said rollers whereby rotation of one of said rollers in one direction will cause synchronous rotation of the other roller in an opposite direction, and means connecting said grip portion and said roller supporting portion whereby at least one finger of the hand which grasps said grip portion may engage and digitally rotate one of said rollers.
  • a finger-training apparatus as set forth in claim 1 characterized in that said rollers have axes of rotation extending obliquely to each other.
  • a finger-training apparatus as set forth in claim 1 characterized in that said rollers provide therearound characterized in that said means connecting said rollers means for facilitating engagement of the fingertips with are intermeshing gears. the roller surfaces.
