Der Tischtennisschläger hat unterschiedlich geformte Griffschalen (14, 16), wodurch die Vor- und Rückhandseiten des Blatts (10) bestimmt sind. Im Gegensatz zu bekannten anatomischen Griffen haben jedoch die Griffschalen (14, 16) sehr einfache geometrische Formen. Bei im mittleren Bereich im wesentlichen symmetrisch zur Mittellängsachse geformtem Griff ist die rückhandseitige Griffschale (16) bis zu ihrer Vorderkante (22) mit etwa gleichbleibender Dicke ausgebildet. Ausserdem reicht sie über das nach vorn abgeschrägte vordere Ende der vorhandseitigen Griffschale (14) hinaus. Um dennoch auf beiden Seiten des Blatts gleich große Beläge anbringen zu können, ist der vordere Bereich der rückhandseitigen Griffschale (16) hinterschnitten.

The proposed device enables to improve cushioning properties, increase ball flying speed, improve twisting of a ball. The said technical effect is achieved owing to that the proposed bat comprises a base, a handle and an elastic pad connected to the base outer surface. Protrusions on the elastic pad are distributed evenly. The said protrusions are made T-shaped, in the form of a leg and a head combined with the said leg. The legs are connected to the elastic pad. The heads of the neighboring T-shaped protrusions are brought into contact therebetween.

The invention relates to a ball-hitting sole for a table tennis racket, including a flexible coating (118) made of an elastic material and having one surface (135) provided with elastically deformable lugs (120) projecting from said surface. The cross-sections of said lugs are larger in the areas (122) for the connection thereof to the coating than in the areas close to the opposite ends (124) thereof, and the side walls (125) of said lugs have concave curved profiles on at least a portion of the height of the lugs between said two areas. The sole can particularly be used in a table tennis racket in which the surface with the lugs (120) of said sole (112) is facing the inner side of the racket paddle (115) so that the free ends (124) of the lugs, which have side surfaces with concave curved profiles (125), are applied against a layer (126) of an elastic material connected to the paddle and having an elasticity modulus substantially lower than that of the elastic coating (118) of the sole. The smooth surface (115-1) of the sole opposite the lugs (120) defines the hitting surface of the racket.
摘要:
A table tennis racket for shakehand grip style, in which a player having an index finger in contact with a backhand side of a racket body while grasping a handgrip of the racket with a thumb and middle, ring, and little fingers. The player can enhance powerful offensive strokes, and does not immoderately move his or her wrist when flipping the batting side to use both sides of the racket during a game. A beginner can easily enjoy playing table tennis using both sides of the racket with little slide and shake. The table tennis racket includes a racket body; two hitting surfaces formed on both sides of the body, each of the hitting surfaces covered with a rubber sheet; a handgrip extending downwards from the racket body; and projections extending outwards from an outer surface of the handgrip and supported by player's fingers when a player grips the handgrip.
摘要:
A racket is described, with a center of gravity thereof being approximate to a center of a rubber sheet of the racket, and a center of gravity that moves approximately to the center of rubber sheet and is located in a high ball-strike area. The racket has a substantially triangular blade. The blade comprises a head, a neck and a handle. The head becomes gradually narrower from front to back of the head, and the handle can further be lightened. The center of gravity of the racket can thereby move forward to the center of the rubber sheet to enhance attack and defense abilities of the racket, and reduce shock.

Proposed is a table-tenis bat with a single-piece blade to which covering layers can be attached over the playing surface on one or both sides, the bat having a handle built round an extension of the bat blade which runs down the whole length of the handle and to which side-pieces are attached on each side. The bat has the following features: one of both of the side-pieces (2) has a recess on the side facing the blade extension, thus forming a cavity inside the handle; viewed at right angles to the handle axis, the cavities have a circular or elliptical cross section; the side-pieces (2) are joined along their whole length at their edges to the blade extension; at the end remote from the playing surface, the side-pieces (2) are open or closed off by a flexible element.

An object of the present invention is to provide laminated lumber that can be widely used as a building material by laminating and securing together a plurality of pieces of lumber such as ones from thinning and that can be produced at low costs by improving the productivity by shortening a duration required to cure laminated lumber, and a method for producing such laminated lumber. To this end, in laminated lumber according to the present invention, a laminated body is formed by softening a plurality of pieces of lumber by treating them with heat and pressure compressing them with an adhesive being interposed between the surfaces of those pieces of lumber, and then a treatment for fixing them to each other is imparted to the laminated body so formed via a heating device. A method of the present invention for producing laminated lumber comprises a first process where respective pieces of lumber are softened by heat treating, a second process where an adhesive is applied onto the surfaces of the respective pieces of lumber so softened, a third process where a laminated body of a predetermined shape is formed by pressure compressing the respective adhesive-applied pieces of lumber, and a fourth process where a fixing treatment is given to the laminated body via a heating device. According to the invention as described above, it is possible to realize laminated lumber that can create a free design using variations of grains and widely be used as a building material by laminating and fixing a plurality of pieces of lumber such as ones from thinning that are less usable and which can be produced at low costs by improving the productivity by shortening a duration required to cure laminated lumber, and a method for producing such laminated lumber.

A flying disk toy (10) includes an annular inner ring (14) centered on the axis and connected with an outer ring (12), and a flexible material secured to the inner ring and creating a trampoline surface (16). The inner ring is detachably received in a groove in the outer ring. The groove has an undercut, and the inner ring has a portion including relatively movable flanges that engage in the undercut in the groove to resist removal of the inner ring from the groove.
