4 Claims, 5 Drawing Figures MEANS FOR ATTACHING PENCILS TO TEMPLATES BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is directed generally to the art of drafting aids and guides and is particularly concerned with those devices of a prior art which require a graphic marking device, such as a pen or pencil, for their end use utilization.

2. Description of the Prior Art There has long existed an unsupplied need for drafting guides such as plastic triangles, templates, and the like,provided with simple clip arrangements for removably retaining pencils, pens, and the like, for convenience and transport and immediate readiness for use. The need is particularly felt among general students who have no need nor desire for the more sophicated devices available to the professional artist or draftsman. Rather the need is directed to inexpensive devices which are readily adaptable to being clipped in a looseleaf notebook for handy use in class or lecture room.

As is well known, pencils, pens and the like are usually carried by students in pockets or purses, and are usually not immediately at hand when they are required for unscheduled and randomly occurring purposes such as occur in class and lecture hall. Likewise, the student may have a template with his orher classroom effects for use as the occasion requires for the rapid sketching of figures and the like. Templates, triangles, and the like are awkward by their very configuration and must of necessity be carried in notebook pockets, on the rings of notebooks, or in similar places.

It is seen from the foregoing that although the template requires a pencil or pen for its use, the two devices are usually not carried in adjacent relationship, hence the student must spend valuable time searching for them in order to bring them together for their cooperative use.

SUMMARY OF THE INVENTION It is the general object of the invention to provide a drafting guide having cooperative devices removably secured together. It is a further general object to provide such a guide in which an instrument having a generally flat planer surface portion is provided with at least one clip outstanding in elevation from the instrument adjacent to the flat planer surface portion, for removably retaining a graphic marking device to be used with the instrument. It is a specific object to provide a guide of the type immediately aforesaid in which the clip is configured with a base portion and a neck portion immediately adjacent the base portion, the neck portion being of reduced section, and further in which the instrument is provided with a generally T-shaped slot within which said base and neck portions of said clip are received. It is an object to provide such a guide in which the T-shaped slot defines inwardly directed shoulders between which said clip neck portion is disposed, the clip having a pair of anns outstanding from the neck portion to overlie the shoulders of the instrument and adapted to removably enfold in part a graphic marking device such as a pen or pencil.

It is a particular object to provide a template and clip combination in which the template is provided with a T-shaped slot and in which the distance spanned between the shoulders of the slot is substantially equal to the thickness of the clip arms, the slot having a longitudinal length sufficient to permit the clip arms there through, whereby the clip arms may be inserted into the slot between the shoulders from below the template and thereafter rotated substantially to overlie the shoulders with the clip firmly secured to the template. It is a further particular object to provide a combination as aforesaid in which said clip arms are lyrately configured of resilient plastic material for relatively soft yielding apart from each other to permit easy insertion and removal of a pen or pencil in the clip.

Other and further objects of the invention will be apparent upon consideration of the drawing when considered with the description thereof, it being obvious that the embodiment shown and described is merely by way of disclosure of the novel elements of the invention without limitation to the specific form so disclosed.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of a drafting guide illustrating a preferred embodiment of the invention; v

FIG. 2 is an enlarged plan view of a portion of a template with a clip inserted through the template slot from below;

FIG. 3 is a view similar to FIG. 2 but showing the clip rotated;

FIG. 4 is an isometric fragmentary view of a portion of a template showing a pair of clips in secured positions; and

FIG. 5 is an enlarged elevation view of a clip and section of a fragment of the template, taken on the line 5-5 of FIG. 4.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawing there is shown a drafting guide 10 having an instrument in the form of a template 12 for guiding graphic marking devices such as pens, pencils, or the like in known manner. The template 12 is provided with spaced apart pulls 14 aligned near the left edge of the template for the purpose of removably securing the template 12 on the snap rings of conventional loose leaf notebooks. The particular template arrangement shown comprising guide edges for alphabet figures, numerals, circles, etc., is merely by way of illustration since the invention is amenable to use with any of a variety of templates such as electrical, electronic, chemical, furniture, architectural, or any of the infinite variety of small flat plastic templates available for use by students as well as technical and professional people.

The template 12 is provided with spaced apart pairs of

slots

16, 18, 20 and 22, as shown here for the reception of clips such as the clips 24 shown disposed in the slots 16. It will be observed that the slots are somewhat elongate along a common axis for each pair. As will be explained in detail below, the elongate slots permit entry, from below the bottom face of the template 12, of the spaced apart arms of the clips, whereafter the clips are rotated 90 about their axis normal to the upper planer surface portion of a template 12 to a position whereat they are adapted to their use as pencil retainers, for example.

Referring more particularly to FIGS. 4 and 5, the fragment 26 of the template 12 shown there discloses the top planner flat surface portion 28 and the parallel bottom planner surface portion 30 having spaced apart slots 16 with clips 24 disposed through the slots.

As best seen in FIG. 5, the slot 16 is generally T- shaped having an enlarged cutout portion 32 and a portion 34 of reduced section defined by inwardly directed

shoulders

36 and 38.

The clip 24 of FIG. is provided with a base portion 40 nested in the enlarged cutout void 32, a neck portion 42 of reduced section disposed between the

shoulders

36 and 38, and a pair of

arms

44 and 46 extending upwardly and divirginly from the neck portion and thereby overlying, at least in part, the

shoulders

36 and 38. Preferrably,

arms

44 and 46 are lyrately configured to removably retain a pencil, for example, shown at 48 in outlying form, wherefor the

arms

44 and 46 converge somewhat from their greatest span to define at their upper end 50 and 52 a spanned distance somewhat less. Preferrably the clip 24 is formed of resilient plastic material for relatively soft resilient yielding of

arms

44 and 46 apart from each other to permit insertion and removal of the pencil by light finger pressure.

Referring now to FIGS. 2 and 3 there is illustrated the simple and novel means by which the clips are secured to the template. For purposes of illustration the insertion of one of the clips 24 of the pair in one of the slots 16 is shown. FIG. 2 is an enlarged plan view of a fragment 26 of the template 12 showing the clip 24 with its

arms

44 and 46 inserted through the slot portion 34, with the clip base 40 nested in the enlarged cutout portion 32 of the slot 16. It will be noted that the thickness of the

arms

44 and 46 is substantially equal to the span of the restricted slot portion 34 between the

shoulders

36 and 38.

Referring now to FIG. 3, it is seen how the clip 24 had been rotated 90 so that the

arms

44 and 46 overlie the

shoulders

36 and 38 for retention of the clip 24 on the template, after the fashion thus seen on FIG. 5.

Accordingly, there has been disclosed a novel drafting guide fulfilling all the objects outlined hereinabove. Although disclosed in combination with a template, it will be recognized by those skilled in the art that the invention has utility in connection with other instruments such as triangles and the like which are utilized, for example, by students in their day-to-day classroom and lecture hall studies.

The inventor claims:
