Abstract
Abstract The kite comprises a sail of flexible fabric, having a relatively large central opening, the sail being held distended by a lateral bar customarily having its ends received in pockets at the lateral margins of the sail, and by two spaced longitudinal bars extending from base to top of the sail and similarly held at their ends and in sleeves in the sail fabric. Carried by the lateral bar is a control strut projecting forwwardly and carrying a transversely extended conntrol bar which is preferably substantially rigid, but which may flex to a limited degree. The control strut receives and holds a third longitudinal bar extending from top to bottom of the sail, the latter having pockets to receive the ends of the longitudinal bar. Since bar is held by the control strut at the fore end of the latter, the third and central longitudinal bar contours the sail centrally and from top to bottom and forwardly, forming a cambered profile of the sail, greatest in the middle and decreasing toward the sail upper and lower tips, the first mentioned longitudinal bars being bowed. In use of the structure, pull cords attached to the ends of the control bar ends are manipulated, and if desired these cords may be attached to a single manipulating line operated by the user.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A kite comprising a sail, means holding the sail in extended condition and consisting of a plurality of bars extending longitudinally of the sail in its position of use, and at least one transverse bar engaging the side margins of the sail, a transverse control bar to the ends of which two kite lines may be attached, and means projecting and holding said control bar substantially spaced from the kite sail, in combination with a control strut forming the means for projecting the control bar, said strut holding and spacing said control bar relatively to the sail and holding and spacing the transverse bar from the control bar, at least one of the bars extending longitudinally of the sail being carried by said strut and held therby longitudinally spaced forwardly of said transverse bar said sail having a substantial opening in its center area, said longitudinal bar carried by the strut crossing said opening and forming V-shaped channels of the sail meeting said opening therein.
Claim 2
Dependent Claim
165 words
A kite comprising a sail, means holding the sail in extended condition and consisting of a plurality of bars extending longitudinally of the sail in its position of use, and at least one transverse bar engaging the side margins of the sail, a transverse control bar to the ends of which two kite lines may be attached, and means projecting and holding said control bar substantially spaced from the kite sail, in combination with a control strut forming the means for projecting the control bar, said strut holding and spacing said control bar relatively to the sail and holding and spacing the transverse bar from the control bar, at least one of the bars extending longitudinally of the sail being carried by said strut and held therby longitudinally spaced forwardly of said transverse bar said sail having a substantial opening in its center area, said longitudinal bar carried by the strut crossing said opening and forming V-shaped channels of the sail meeting said opening therein.
Claim 3
Dependent Claim
141 words
A kite comprising a sail, means holding the sail in extended condition and consisting of a plurality of bars extending longitudinally of the sail in its position of use, and at least one transverse bar engaging the side margins of the sail, a transverse control bar to the ends of which two kite lines may be attached, and means projecting and holding said control bar substantially spaced from the kite sail, in which the transverse bar bears against at least two of the bars extending longitudinally of the sail, and which are relatively spaced, a longitudinally extending bar disposed intermediate said two longitudinally extending bars, a control strut carrying the transverse bar and carrying said intermediate longitudinally extending bar spaced therefrom in such manner as impose stress on the sail and to bow the remaining longitudinally extending bars, and the sail.
Claim 4
Dependent Claim
141 words
A kite comprising a sail, means holding the sail in extended condition and consisting of a plurality of bars extending longitudinally of the sail in its position of use, and at least one transverse bar engaging the side margins of the sail, a transverse control bar to the ends of which two kite lines may be attached, and means projecting and holding said control bar substantially spaced from the kite sail, in which the transverse bar bears against at least two of the bars extending longitudinally of the sail, and which are relatively spaced, a longitudinally extending bar disposed intermediate said two longitudinally extending bars, a control strut carrying the transverse bar and carrying said intermediate longitudinally extending bar spaced therefrom in such manner as impose stress on the sail and to bow the remaining longitudinally extending bars, and the sail.
Claim 5
Dependent Claim
198 words
A kite comprising a sail, means holding the sail in extended condition and consisting of a plurality of bars extending longitudinally of the sail in its condition of use, and at least one transverse bar engaging the side margins of the sail, a transverse control bar to the ends of which two kite lines may be attached, and means projecting and holding said control bar substantially spaced from the kite sail, the sail being of pliable fabric held extended laterally by the transverse bar, the latter bearing against at least two of the longitudinal bars, a forwardly projecting control strut carrying said transverse bar at its rearward end, an additional longitudinal bar element carried by said control strut at its forward end and Bearing against the sail in a forwardly directed manner so that said additional longitudinal bar element produces a V-shaped channel formation centrally and longitudinally in the sail and in opposition to the first named longitudinal bars so that they are bowed, said channel formation of the sail being interrupted by an opening in the sail at its central area, said opening having a transverse width les than the distance between top and bottom t thereof.
