    • A pen comprises an elongated one-piece barrel having substantially rigid tip end and head end portions joined to each other by an intermediate integral flexible portion, whereby the barrel can be bent at the flexible portion, and a writing tip at the distal end of the tip end portion. A substantially rigid tubular cap member is telescopically received over the tip end portion of the barrel such that it can be moved along the barrel between (1) a retracted position in which it overlies part of the tip end portion and substantially all of the flexible portion, thus exposing the writing tip for use and rendering the pen substantially rigid, and (2) an extended position in which it covers the writing tip and leaves the flexible portion exposed, thus protecting the writing tip and rendering the pen flexible. Interengaging rib and groove couplings on the cap and the tip end portion of the barrel releasably retain the cap member in each of the retracted and extended positions.

    • The seat of a chair is mounted on a post or other supporting member by a seat mount which permits the seat to tilt forward (front end down) to a forward and downward rake of about 41/2.degree.. A bracket connected to the seat and located under generally the center of the seat pivots on an axle that is received and supported by a mounting plate rigidly fastened to the supporting member. Springs compressed between the mounting plate and the bracket restrain the seat from tilting down, and co-engageable stop surfaces associated with the bracket and mounting plate limit the extent of tilting of the seat (both forward and backward rake, when the latter is provided for). By joining the mounting plate and bracket by parallel front and rear axles fixed to the bracket and arranged to disengage axle-engaging surfaces on the plate, or vice versa, the seat can tilt both forward and backward; in this mode, the seat pivots or rocks on one axle, and the other axle disengages the axle-engaging surface. An optional movable blocking element can be included to disable the rearward tilt mode when desired.
    • 椅子的座椅通过座椅安装件安装在柱子或其他支撑构件上,该座椅座椅允许座椅向前(前端向下)倾斜到大约41/2度的向前和向下的耙子。 连接到所述座椅并且位于所述座椅的大致中心下方的支架在轴上枢转,所述轴由刚性地紧固到所述支撑构件的安装板接收和支撑。 在安装板和支架之间压缩的弹簧限制座椅向下倾斜,并且与支架和安装板相关联的可共同的止动表面限制了座椅倾斜的程度(向前和向后耙子,当后者被提供用于 )。 通过将固定在支架上的平行的前轴和后桥连接安装板和支架,并将其布置成脱离板上的轴接合表面,反之亦然,座椅可以向前和向后倾斜; 在这种模式下,座椅在一个轴上枢转或摇动,另一个轴与轴接合表面脱离。 可以包括可选的可移动阻挡元件,以在需要时禁用向后倾斜模式。
