    • A sailboat hull comprised of a monolithic structure fabricated of low-density polymer foam and having integrally formed therewith an internal H-shaped structure. The H-shaped structure serves to reinforce the hull and provides buoyancy chambers extending along either side of the hull and a centerboard trunk medially of the hull. The chambers define leg space therebetween and are so proportioned that said leg space is buoyantly supported above the surface of the water when the hull is in a tipped vertically disposed position. The hull is provided with a rudder comprised of a pair of separate cheek plates vertically disposed in spaced parallel relationship to one another and held in this position by extruded aluminum pintle blocks secured between the plates. The pintle blocks extend forwardly of the plates and carry aligned pintle pins. A tiller is fixedly attached between the upper edges of the plates and the rudder is pivotally secured between the plates beneath the tiller.
    • 帆船船体由由低密度聚合物泡沫制成并且与其一体形成内部H形结构的整体结构组成。 H形结构用于加固船体,并提供沿船体两侧延伸的浮力舱和船体中间的中间板舱。 这些室限定了它们之间的腿部空间并且具有如此的比例,使得当船体处于倾斜的垂直设置位置时,所述腿部空间被浮力地支撑在水面上方。 船体设置有方向舵,该方向舵由垂直设置成彼此间隔成平行关系的一对独立的颊板组成,并通过固定在板之间的挤压铝栓栓块保持在该位置。 枢栓块向前延伸,并带有对准的针栓。 舵柄固定在板的上边缘之间,方向舵枢转地固定在耕作机下面的板之间。

    • Disclosed are expansible clasp and module constructions for connecting the free ends of a watch strap together while at the same time providing adequate expansion along the length of the strap to permit removal of the strap over the hand of the wearer without having to disconnect the free strap ends. The expansible clasp and module constructions employ one or more spring-biased sliding members disposed in a housing elongated along the strap length. In the clasp construction, the outer end of the sliding member effects releasable connection to one free strap end while one end of the housing is permanently attached to the other free strap end. The sliding member slides out of the housing against the spring bias in one direction along the strap length for expansion purposes during removal of the strap. In the module construction, a pair of superimposed sliding members is positioned in the housing with the outer end of each sliding member permanently attached to the adjacent free strap end at opposite ends of the housing. The sliding members slide out of the housing in opposite directions against the spring bias to provide for expansion in both directions along the length of the strap while the housing floats therebetween. Removal of the strap over the hand of the wearer without disconnecting the strap ends is thus greatly facilitated.
    • 公开了用于将表带的自由端连接在一起的可膨胀的扣环和模块结构,同时沿着带的长度提供足够的膨胀,以允许将绑带移除穿戴者的手,而不必断开自由带 结束。 可膨胀的扣环和模块结构使用一个或多个弹簧偏置的滑动构件,其布置在沿着带长度延伸的壳体中。 在扣环结构中,滑动构件的外端实现与一个自由带端部的可释放连接,而壳体的一端永久地附接到另一自由带端部。 滑动构件在拆卸带的过程中沿着带长度在一个方向上抵抗弹簧偏压滑出外壳以用于扩展目的。 在模块构造中,一对叠置的滑动构件定位在壳体中,每个滑动构件的外端永久地附接到壳体的相对端处的相邻自由带端部。 滑动构件抵抗弹簧偏压从相反的方向滑出壳体,以沿着带的长度在两个方向上膨胀,同时壳体在其间浮动。 因此,极大地方便了在佩戴者的手上去除皮带而不断开皮带末端。
