摘要： A new dart has an integrally formed flight part that is made of thin plastic with a uniform thickness. The flight part has a set of flexible blades that are radially offset, with the width of each blades being coplanar, and extending perpendicular to the longitudinal axis of a stem on which a barrel and dart tip are connected. Edges on a central portion of the flight part engage cooperating surfaces on a retainer, locking the retainer and the flight part against rotation with respect to each other. A self-lubricating bearing fits over the a stem and is used to connect to the flight part and the retainer for rotation with respect to a barrel and dart tip. A channel extends along the length of each blade. A bubble is positioned outwardly of the channel.

摘要： A puzzle assembly having a plurality of pieces which are identical and which interfit without interlocking are assembled in a recess of the base of a container and the container is closed by a cover hinged to the base. When the cover is closed, the puzzle pieces are disposed between top and bottom walls formed respectively on the cover and the base. The pieces are made of a resiliently yieldable material and their normal thickness is greater than the spacing between the walls when the cover is closed so that the pieces are clamped between the walls and are held against sliding even though only some of the pieces have been assembled. The puzzle has a design on both sides and the top and bottom walls are transparent so that both designs may be viewed with the cover closed.

摘要翻译： 具有多个相同并且没有互锁的互补件的拼图组件被组装在容器的基部的凹部中，并且容器由铰接到基座的盖封闭。 当盖子关闭时，拼图件分别设置在分别形成在盖子和底座上的顶壁和底壁之间。 这些部件由弹性屈服材料制成，并且当盖子关闭时它们的正常厚度大于壁之间的间隔，使得这些部件被夹紧在壁之间并且被保持抵抗滑动，即使只有一些部件已经被组装 。 拼图具有两侧的设计，顶壁和底壁是透明的，因此两个设计都可以在盖子关闭的情况下观看。
