摘要： A curved ergonomic pen which facilitates writing on vertical surfaces comprises a housing having a barrel portion and a web portion. The barrel has curved inner and outer edges and substantially flat sides. The web is substantially flat and extends along the curved inner edge of the barrel. A curved channel is formed in the barrel in communication with openings in opposite ends of the barrel. A pair of ink cartridges each comprising an ink tube and a tip secured to one end thereof are retractably secured within the channel such that the respective tips generally extend toward opposite ends of the barrel. The pen tips are selectively extendable and retractable through the associated openings in the opposite ends of the barrel. In one embodiment, a note pocket for receiving relatively small sheets of paper is removably securable within a slot extending into an outer edge of the web. A cover is provided which is removably securable to the housing to cover both ends of the housing and any tips extending therefrom.
摘要翻译：易于在垂直表面上书写的弯曲人体工程学笔包括具有筒部和腹板部分的壳体。桶具有弯曲的内边缘和外边缘以及基本平坦的边。纸幅基本上是平的并且沿着镜筒的弯曲的内边缘延伸。在筒体中形成有与筒体的相对端部的开口连通的弯曲通道。一对墨盒，每个墨盒包括一个墨水管和一个固定在其一端的尖端，这些墨盒可收缩地固定在通道内，使得各个尖端大体上朝着镜筒的相对端延伸。笔尖可以选择性地延伸和缩回通过筒的相对端中的相关联的开口。在一个实施例中，用于接收相对小的纸张的钞票袋可移除地固定在延伸到幅材的外边缘的狭槽内。提供了一个盖子，其可拆卸地固定到壳体以覆盖壳体的两端和从其延伸的任何尖端。

摘要： A ball point pen body includes a pair of oppositely disposed ink cartridges. An aperture is formed at each end of the body and segments of the body are forced together to simultaneously project a ball point end of each cartridge through one of the apertures. The base end of each ink cartridge is fixed to a separate body segment by engagement with a self seating split ring retainer. Relative movement of the body segments toward or away from each other is guided by a track formed in a telescoping sleeve which frictionally holds the body segments in their selected relative positions with the ball points either projecting from the apertures for writing or retracted into the body.
摘要翻译：圆珠笔体包括一对相对设置的墨盒。在主体的每个端部处形成有孔，并且主体的部分被压在一起，以同时使每个盒的圆珠笔端通过其中一个孔突出。每个墨盒的基端通过与自身座圈分隔环保持器的接合而固定到单独的主体部分。身体部分相对于彼此相对或远离的相对运动由形成在伸缩套筒中的轨道引导，该轨道将身体段摩擦地保持在其选定的相对位置，其中球点从用于书写或缩回到身体中的孔突出。
