Abstract: The ball for ball games has a ball body and a spherical shell-shaped outer layer having a plurality of leather panels and disposed on the outside of the ball body. The plurality of leather panels each have a main body and an extending portion that is thinner than the main body and extends from a front-side portion of an outer end surface of the main body to configure an outer end surface of the leather panel. The extending portions of adjacent leather panels are bonded to each other with an adhesive and stitched together with a stitching thread. In the ball for ball games, the extending portion is provided with a reinforcing member for reinforcing an area thereof stitched with the stitching thread.

Abstract: A whistle includes: an air supply opening; a first resonance chamber, a second resonance chamber and a third resonance chamber; a first air supply passage, a second air supply passage and a third air supply passage that branch from a common air supply passage; and a first sound emitting opening, a second sound emitting opening and a third sound emitting opening that emit sounds generated in the first resonance chamber, the second resonance chamber and the third resonance chamber, respectively. The first resonance chamber and the second resonance chamber are arranged side by side in a planar view. The third resonance chamber is disposed between the first resonance chamber and the second resonance chamber, as well as upside the first resonance chamber and the second resonance chamber. The first sound emitting opening, the second sound emitting opening and the third sound emitting opening are open upward.

Abstract: A method of manufacturing a multi-layer outer panel for a game ball includes three-dimensionally forming a top layer of an outer panel, as well as one or more backing materials disposed underneath the top layer, into a shape substantially corresponding to the surface of the ball. Multi-layer outer panels are then attached to or interconnected to surround an inflatable bladder, thereby producing a game ball while minimizing overstretching of the outer material or the backing material and improving resistance of the outer panels to delamination.

Abstract: There is provided a whistle which suppresses any delay of sound to a listener and any attenuation of a sound volume, can transmit sound waves directly, can be blown with various tones, and has a large sound volume. Two kinds of whistles are stacked up and down and integrated together as a single whistle, an orifice is formed opposite to an air feeding opening to transmit sound waves directly to a listener. Moreover, an amount of air flowing into each air feeding tube of the whistle is controlled depending on an angle of putting a mouthpiece in a mouth to select a tone. A tone selecting member or an air amount adjusting flap is provided, and tone can be selected by mechanically blocking off each air feeding tube. Furthermore, an air amount adjusting flap which changes an air-feeding-path cross-sectional area of the air feeding opening, the air feeding tube, or the orifice is provided, and a sound volume can be changed by adjusting an amount of passing air.

In order to attain this object, a whistle comprises a mouthpiece portion, inside which an air passageway is formed and in which an air opening is opened, and a body portion, in which a connected resonance chamber that is connected to the air passageway is formed; the connected resonance chamber comprises a first resonance chamber, a second resonance chamber in which a sound-emitting opening is opened, and an orifice connecting the first resonance chamber and the second resonance chamber.

Abstract: A whistle is provided with an interior that can be cleaned. The whistle has a body with a resonance chamber wall. One face of a resonance chamber formed by the resonance chamber wall is open. A side plate is formed separately from the body, and can be attached to and removed from the body. The side plate has a first portion that blocks the one face of the resonance chamber when attached to the body. A first flange is provided on the first portion and is engageable with the resonance chamber wall. At least one of the resonance chamber wall and the first flange is elastically deformable. An air passageway, the resonance chamber, an air opening that is opened in the air passageway, and a sound-emitting opening that is opened in the resonance chamber are formed by the body and the side plate.

Abstract: A method of manufacturing a multi-layer outer panel for a game ball includes three-dimensionally forming a top layer of an outer panel, as well as one or more backing materials disposed underneath the top layer, into a shape substantially corresponding to the surface of the ball. Multi-layer outer panels are then attached to or interconnected to surround an inflatable bladder, thereby producing a game ball while minimizing overstretching of the outer material or the backing material and improving resistance of the outer panels to delamination.

Abstract: The ball for a ball game of the invention includes a fabric layer 1 having a spherical 12-hedron where twelve right pentagonal fabric pieces 2 are sewn together. The marginal edges of the fabric piece being folded by 90 degrees, and the marginal edges are sewn together with a sewing machine. The fabric layer is then reversed through cross-like slits 5a, 5b formed in the fabric layer in a location opposite to a valve opening 5 (also formed in the fabric layer) in such a manner that the marginal edges are located on an inner side of the fabric layer. After the bladder is accommodated within the fabric layer through the closure hole 5, the hole 5 is closed by a patch. Onto a surface of the fabric layer, there is adhered the panels. Thereby, the ball for a ball game having no unevenness and soft feeling is attained.

Abstract: To provide a ball for ball game and a method for manufacturing the ball having superior sphericity, an ability to retain its original shape, durability, and soft feel. The fabric layer (12) is formed by sewing with a sewing machine for instance pentagonal first fabric pieces (13) together with composite shaped second fabric pieces (14) in which two hexagons are connected with each other, so that a spherical shape is formed. The marginal edge of the first and second fabric pieces are superimposed in the spherical surface direction, so that corner portions thereof are temporarily attached. Temporary attachment is achieved by inserting the needle into the needle through hole formed in the corner of the first and second fabric pieces, and welding by means of ultra sonic wave, such that the first and second fabric pieces (13, 14) are accurately aligned.
