Title: Frame of racket for ball game and its production
Inventor: MAIKERU EDOWAADO KAACHISU
IPC: A63B49/00
Filed: 1985-07-17
Abstract: The invention relates to a frame for a games racket e.g. tennis, of the type made as a hollow injection moulding of reinforced thermoplastics material. The frame has stringing means in the form of a series of discrete lugs (17, 28 or 40) moulded integrally with the walls of the hollow frame and so positioned that the racket strings in their desired positions do not pass to the outer periphery of the head. The discrete lugs may for example be around the inner periphery of the head of the frame and each contain an integrally-moulded circumferential bore (18) for string passage.The frame may be made by injection moulding around a fusible core (10, 21 or 30) and the shape of the core required to give the desired lugs provides strong resistance to movement under the injecting pressures hence giving improved product uniformity.

An electromagnetic valve 4 of the dehumidifying device 2 is then turned off by a relay 3, and a valve bar 5 is placed in an exhaust position as shown in a drawing. An upper surface of an upper bellowframe of a drain valve 6 is brought into a nonpressure state, and a valve 6A is closed. Thus, compressed air is dried after passing through an element 11 and a check valve 12, and is fed to a regenerative air reservoir and a relay chamber 17 for storing therein. Afterwards, with the compressor stopped running resulting from the rise in the pressure in the main reservoir, a valve 4 turns on, and compressed air in the chamber 17 flows into a chamber 16.
