3~;3 DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
Although specific terms are used m the follow m g description for the sake of clarity, these term are intended to refer only to the particular structure of the invention selected for illustration in the drawings, and are not intended to define or limit the ooze of the mventio~.
Referring now to the draw mugs, where is shown m Figs 1, 2, and 3 a combination marker pen clip 10 and a separate pen device or marker pen 12.
It is a purpose of this invention to provide a construction whereby the pen device 12 can be easily and accurately associated with or disassembled from the clip 10. When the separate parts 10, 12 are assembled as in Figs. 1 and 3, the interaction of the various interlocking components function to prevent longitudinal or transverse moments of the pen device relative to the clip Still referring to Figs. 1-3, the pen device 12 comprises generally an ink or other irking fluid contain my cartridge 14 and stylus 16, the stylus being in fluid communication with the ink (not Chicano) in well known manner.
As illustrated, the cartridge 14 is generally rectangular in planar configuration and includes a top surface 48, a bottom surf ox 50 and a peripheral side walls 52 extending there between.
The stylus 16 projects downwardly from the bottom surface 50 for applying a continuous line up a conventional chart or graph in well known manner. Immediately adjacent to and rearwardly of the stylus are provided a pair of downwardly extending projections or stabilizers 24, 26 for engagement with the nose or forward end 44 of the clip 10 in the manner hereinafter more fully set forth. Rearwardly of and substantially in longitudinal alignment with the projections 24, 26 are provided a pair of spaced, longitudinally extending ridges 28, 30, which ridges serve to position and laterally restrain the association of the cartridge 12 upon the marker clip 10 as herein more fully discussed. Preferably, the ridges 28, 30 terminate rearwardly in sloping ends 58 to facilitate slip on assembly Len the parts are associated.
~2~3~3 Referring ocularly now to Figs. 2, 3 and 7, the clip 10 comprises generally an elongate body 46 which terminates rearwardly in a connection to the writing arm 20 in known manner, for example by enjoying a plurality of spot welds 22. The clip body terminates forwardly in a forward end or nose 44 which nose is configured to lie in a plane transverse to the longitudinal axis of the body 46. The forward portion of the body is punched, machined or otherwise warred to provide a pair of laterally spayed, longitudinally extending, parallel, elongated slots 40, 42 of size and configuration to receive therein the corresponding downwardly projecting ridges 28, 30 which depend f m m the bottom surface 50 of the cartridge 14. It is a feature of this Invention that the cartridge ridges 28, 30 and the clip slots 40, 42 cooperate whereby the ridges 28, 30 seat within the respective slots 40, 42 when the parts are assembled in a wanner to prevent either longitudinal or transverse relative movement between the cartridge 14 and the clip 10.
The forward portion of the clip 10 also Includes a pair of laterally spate d, upwardly projecting flanges 32, 34, which flanges are formed at an acute angle with the plane of the clip body 46 to provide frictional engagement forces upon the longitudinal side walls 52 of the cartridge 14 upon assembly. See Fig. 5. Each flange 32, 34 terminates upwardly in a bent shoulder 36, 38, which shoulders bear against and frictionally engage the cartridge sidewall 52 to secure the parts together. As best seen in Figs. 3 and 6, upon assembly of the parts, the forward end or nose 44 of the clip 10 abuts and positions against the projecting stabilizes 24, 26 which depend from the bottom surface 50 of the cartridge 14 to provide an easily I assembled positioning arrangement whereby the position of the cartridge relative by the clip 10 is automatically and mechanically predetermined.
The interaction of the clip nose 44 with the stabile ens 24, 26 and the additional interaction of the clip elongated slots 40, 42 and the cartridge ridges 28, 30 serve to assure that there is not longitudinal or ~ransver æ
relative movement between the cartridge 14 and eye clip 46. The frictional engagement of the flanges 32, 34 against the cartridge sidewalls 52 serves further to prevent relative rnavement between the parts and to facilitate ~2~3~
easy engagement and disengagenYn~ of a marker pan 12 from a marker pen clip 10 when pen replacement becomes necessary. Preferably the cartridge sidewall 52 is provided near the cartridge bottom with opposed transversely extending ledges 54, 56 to additionally frictionally engage the clip flanges 32, 34 respectively.
In order to use the combination marker pen clip and parker pen in accon~an ox with the prevent invention, the clip 10 is preferably positioned with the flanges or tabs 32, 34 facing upwardly and the cartridge 14 and stylus 16 facing downwardly as illustrated in Figs. 1 and 6. With the parts thus positioned, the clip 10 is applied upwardly against the bottom surface 50 of the cartridge 14 with the elongated slots 40, 42 in registry aver the ridges 28, 30 so what the ridges 28, 30 project downwardly through the elongated slots, 40, 42 as illustrated in Fig. 5. With the ridges and slots so positioned, the cartridge 14 can be pushed between the clip flanges 32, 34 so that the bent shoulders 36, 38 of the flanges will bear against and frictionally grip the cartridge sidewalls 52.
The clip 10 end parker pen 12 are pushed completely together by urging the shoulders 36, 38 upwardly along the cartridge sidewalls 52 until face to face contact is made. The inter engagement between the flanges 32, 34 and the elongated slots 40, 42 will so position the nose or forward end 44 of the clip 10 to provide a two point engagement, that is the nose 44 will touch portions of the Rand peripheries of the spaced pro cations or stabilizers 24, 26. In a preferred embodiment, the ridges 28, 30 are rearwardly formed with sloping surfaces 58 to provide twin ramps leading from the cartridge bottom surface 50. The ramps 58 facilitate assembly by permitting the clip nose 44 to slide aver the Betty surface of the cartridge 14, ate rasps 53, and the ridges 28, 30 until the ridges snap into and lock into the corresponding clip slots 40, 42. When the parts are fully assembled, tote bridge 60 which is defined immediately behind the clip nose 44 and forwardly of the slots 40, 42 will also snip into and lock within the l planar area 62 wicket is refined between the cartridge ridges 28, 30 and 1 stabilizers 24, 26.
1.3f~3 Thus it is seen that the interaction and interlocking of the various flanges, ridges, slots/ ledges, projections, bridge and so of the clip will provide a c~plete~ easily transverse or pivotal movement between the clip 10 and the pen device or marker pen 12.
While the interlocking construction features function well to prevent relative r~vement between the clip 10 and the pen device 12, it will be appreciated that the clip flanges 32, 34 define an upwardly open space to receive to the cartridge 14 there within. curd m guy, the cartridge 14 can he relatively easily replaced by simply pulling the cartridge 14 upwardly away from the clip 10 with a force sufficient to overcome the frictional engagement between the clip flanges 32, 34 and the cartridge sidewalls 520 Although the invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
