Abstract: A winding device 1 including a base 3 including a drum accommodation portion 33 that accommodates a drum 4 including upward teeth 46, the accommodation portion 33 being cylindrical and having a closed end, and a dial 5 including downward teeth (53) to rotate the drum 4. The dial 5 is moved to a locked state in which the downward teeth are engaged with the upward teeth 46 to transmit rotation of the dial 5 to the drum 4 and an unlocked state in which the downward teeth are disengaged from the upward teeth 46. The winding device 1 includes an annular gear (51) including projections and roots extending in the rotation axis direction of the dial 5 and a pawl 36 protruding from the drum accommodation portion 33. The pawl 36 is designed to engage with the annular gear. The annular gear and the pawl 36 control rotation of the dial.

Abstract: It is an object of the present invention to provide a winding device that can correctly and separately rotate and drive two winding units by changing a rotation direction of a handle.

Abstract: A structure for attaching a shoelace winding apparatus in which a shoelace winding apparatus can be attached to a shoe is provided. The structure includes a reel that winds a shoelace by being rotated by an operation handle, a ratchet pawl that limits rotation of the reel, and a base member including a substantially cylindrical body that accommodates the reel. The base member includes an annular gear with teeth that engages with the ratchet pawl. The structure includes a base-member attachment cover and a flange portion. The cover includes a substantially cylindrical cover portion with a closed end. The cover portion secures the base member such that the base member is directly attachable and detachable from an outside of an upper section and held in the cover portion. The flange portion protrudes from the circumference of the cover portion and conforms to the shape of the shoe.

Abstract: A shoelace winding reel for a shoelace winding device that is compact and light weight, with superior durability and assembly workability. The shoelace winding reel is housed in a reel storing section of a base member and is configured to be rotatively driven by a dial. The shoelace winding reel includes a rotation shaft portion arranged on an inner side of the shoelace winding drum and an annular portion configured to connect an inner circumferential surface of the shoelace winding drum and an outer circumferential surface of the rotation shaft portion. An annular groove portion is configured to sandwich a tip end portion of the shoelace.

Abstract: A small-sized and light weighted shoelace winding device having superior durability, operability, and maintenance, and that can conveniently be used in various types of shoes is provided. A shoelace winding device includes a base member including a reel storing section for storing a shoelace winding reel, a shaft member for attaching a dial for rotatively driving the reel to the base member, and retaining and guiding the dial in a state of being movable between a lock position and a release position, and a spring member having one end portion axially supported by a bearing section of the shaft member, and its other end portion making constant contact with an engaging portion provided on an inner surface of the dial.

Abstract: It is aimed at providing a golf address deviation detecting apparatus capable of detecting as to which of inaccuracy in loft angle, inaccuracy in lie angle, and inaccuracy in face orientation, inaccuracy, if any, occurred upon address by golf club is caused by. There is provided an apparatus comprising a light reflecting section(s) and light irradiating units, so that inaccuracies in loft angle, lie angle, and face orientation are detected and distinguished from one another, based on differences among patterns of the light-beams reflected by the light reflecting section(s).

Abstract: An angle adjuster for a golf club shaft includes a pressing part that can advance and retreat towards and away from a space between two pressing force receiving parts. The pressing force receiving parts include grooves configured to receive a golf club shaft. When the pressing part is advanced against the golf club shaft, a bending force is applied to the shaft at a bending location on the shaft that lies between the pressing force receiving parts. This occurs while the shaft is received in, the receiving grooves of the pressing force receiving parts.

Abstract: Provided is a putting-training tool for enabling a user to train the putting while realizing that the error of a ball hitting angle may be confined within about 2 degrees. The putting-training tool is characterized in that a golf ball rolling groove has a width of 9 mm to 5 mm and has a transverse section gently-recessed into a curved face for supporting a golf ball at one point, so that the golf ball may not leave, in case a putting force to roll the golf ball by about 1.5 m to 2 m on the green is applied, the golf ball rolling groove for errors of the ball hitting angle less than 2 degrees.

Abstract: A system for judging a ski or snowboard allows a ski board or snowboard most suitable for each skier or snowboarder to be judged by considering the leg strength of each skier or snowboarder. The system includes a storage means for storing a bending characteristic of the ski or snowboard, an input means for inputting the weight and leg strength of the skier or snowboarder, a board characteristic detecting means for determining a bending characteristic of a ski or snowboard that corresponds to the weight and leg strength, and a board searching means for searching the storage means for skis or snowboards that correspond to the bending characteristics determined by the board characteristic detecting means.

Abstract: A leg strength measuring apparatus is capable of measuring a gravity center distribution of loads and leg strength which can in turn serve as a reference for the selection of a ski, a snowboard, ski boots, or snowboarding boots appropriate for a user of the apparatus. The leg strength measuring apparatus includes two footplates upon which a person to be measured steps separately with his left and right feet, and load sensors for detecting loads applied to each of the footplates at least at three points.

Abstract: The present invention relates to spikes for golf shoes that ensure stability while walking and a sufficient gripping force for any green surface on a golf course, and that will never damage a delicate green surface such as a putting green. The spike for golf shoes is characterized by comprising a plurality of leg portions (2) extending downward from a spike main body (1), and a rounded bulge (B) formed on the front-end of each leg portion (2), wherein there will be no sharp portion produced in a bulge (B) even if the bulge (B) wears out.

Abstract: A cleat (10) to be used on a golf shoe is disclosed. The cleat (10) includes a cleat body (3), securing means (4) and a plurality of long legs (1) and short legs (2). The long legs (1) and the short legs (2) are provided alternately on the cleat body (3). The long legs (1) protrude outwardly from the cleat body (3) having an angle with an imaginary plane normal to the axis of the cleat in the range 70±15 degrees. The long legs (1) are rigid enough to penetrate through grass while the short legs (2) are rigid enough to retain their shape on a hard surface and press grass hard from above. The cleat having voids between the long and short legs provides excellent grips on grass as grass blades and stalks enter the voids and entangle with the long legs (1) and the short legs (2).

Abstract: A plastic cleat (10) for a golf shoe is disclosed, including a cleat body (3), a plurality of flexible protrusions (1) and rigid protrusions (2) extending from the cleat body (3). The flexible protrusions (1) and rigid protrusions (2) provide good grips on grass without damaging the grass. The flexible protrusions (1) bend outwardly on a hard surface, when the rigid protrusions (2) chiefly support weight. The cleat (10) can be economically manufactured by “forced extraction molding” utilizing the shape rebounding nature of half hardened plastic materials.
