A table tennis racket includes a rubber (4) attached onto a blade (3) and easily removable without releasing any air-polluting gas. Opposing surfaces of the blade (3) and the rubber (4) have fine pores and lands of a micro-foam material, and the rubber (4) is removably held on the blade (3) with a vacuum suction force produced between the blade (3) and rubber (4) when pressed together.

Durch das bestehende Regelwerk des internationalen Tischtennisverbandes, welches die überwiegende Verwendung von Holz zur Herstellung eines Tischtennisschlägers (1) vorschreibt, werden diese noch heute in verleimten Holzfurnier produziert. Trotz dieser Hemmnisse wurden Tischtennisschläger (1) aus Faserverbundmaterial im Blasverfahren erdacht und hergestellt. Durch dieses neue Herstellungsverfahren ist es nun auch möglich, den Schläger (1) in einem Stück zu produzieren. Das Blasverfahren gestaltet sich prinzipiell folgendermaßen: Man bringt mit Harz vorimprägnierte Fasern auf einen Blasschlauch (7) auf und härtet das Ganze in einer Negativ-Form (13) unter Hitze aus. Dabei wird der Schlauch (7) aufgeblasen und drückt die Fasern mit dem Harz gegen die Negativ-Form (13). Das fertige Produkt ist nun hohl.

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.

The invention relates to leisure and especially sporting activities and, in particular, to a device consisting of two table halves (1, 1') mounted on foldable or non-foldable legs assembled together by means of an attachment device secured to each side of the table halves which form, on the assembly line, two circular recesses, wherein are inserted the studs of two posts (7, 7') for a net (6). The two table halves (1, 1') have several circular openings (3) which can be closed by disks (4, 4') having substantially the same diameter and removable by means of a median opening. Used for racket and bull type sports.

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.

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.
