FIG.
COMPASS BALLPOINT PEN The present invention relates to a tool formed by a body enclosing a ballpoint pen to which, is affixed, a rod which acts as a point of a compass, and which makes it possible, by using the writing point of the pen, to draw circumferences of predetermined diameters.
Such a tool as expected cannot be a tool of exacting precision, but rather it is a practical tool, which allows the use of the ballpoint pen in all usual ways and, furthermore when one needs to make drawings, diagrams, etc. permits the use of compass in order to make use of its special features.
It is one object of the present invention, to provide a compass ballpoint pen combination, wherein the cost of manufacturing of the combination is very low, with the simple use of plastic material of practically no cost, comprising an inner compartment, offset somewhat with respect to the axis of the case, and receiving therein a flexible ballpoint pen cartridge.
Following the curved surfaces of the case, on the outside, a vertical depression is formed with a sufficient cross-section to allow same to receive therein a pivotal compass point arm which, when folded down, fits completely into the outer surface of the case in the depression.
It is another object of the present invention, to provide a compass ballpoint pen combination, wherein the upper end of the compass point arm widens and is pivotally mounted on, and attached to a bolt or transversal pin provided on the head of the case, and which, furthermore, has two parallel grooves, which make it possible to articulate the point in order to set the openings and determine the radius of the circumference to be drawn.
It is still another object of the present invention, to provide a part on the upper end of the case, which part protrudes over the bolt and is cylindrical and striated in order to facilitate the handling of the tool, when it is used as a compass.
With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:
FIG. 1 is an axial section of the entire unit; the compass point being shown in dotted lines in an extended position;
FIG. 2 is a front elevational view of the ballpoint pen with the compass point arm folded back; and
FIG. 3 is a top plan view of the ballpoint pen, shown in FIG. 2.
Referring now to the drawing, the compass ballpoint pen combination comprises a case, made of preferably plastic material, on the inside of which there is a formed a compartment 2, which houses a flexible and replaceable cartridge 4 of the ballpoint pen, the latter ending in a writing point 5.
Vertically extendingand following the curved surfaces of the case 1, there is formed a vertical depression 3 which houses a compass point arm 6 which, when its needle 8 is retracted, fits complementarily into the depression 3. In order to adjust the needle 8, a small grooved wheel 7 is provided. The depression is formed with a circular widening just at the height of a wheel 7 and complementary to its periphery 3a, so that it will fit in.
2 On the upper end of the arm 6, a flap 9 is pivotally mounted on a transverse pin 10 in a direction opposite to a couple of vertical grooves 11, which are diametrically opposed and which make possible the free articulation of the flap 9 on the pin 10.
A jointed clamp 13 is provided over the pin 10 and astride the flap 9, on which clamp 13, a pommel 12 is screwed, in order to improve the effectiveness of the compass.
When the arm of the compass is folded downwardly, one may make normal use of the ballpoint pen, since the diameter of the case 1, is slightly enlarged, but still falls within usual norms, and which permits the perfect use of the writing tool which, when the arm 6 is extended and set on a point with an appropriate radius for the opening, the pen will serve as the tracing end of a compass.
While I have disclosed one embodiment of the present invention, it is to be understood, that this embodiment is given by example only, and not in a limiting sense.
I claim:
1. A compass ballpoint pen comprising a case having curved surfaces and defining an axially offset peripherally closed asymmetric compartment,
a ballpoint pen cartridge disposed in said compartment and having a pen point extending at one end through said case,
said case forming a vertical extending depression following said curved surfaces and opening towards the outside,
a compass point arm having a compass point adjacent said one end and being pivotally mounted to the other end of said case at its end remote from said compass point in said depression,
said asymmetric compartment being narrowest adjacent said other end of said case and widest adjacent said one end,
said depression being widest adjacent said other end of said case and narrowest adjacentsaid one end, such that said compartment and said depression complementarily define a cylindrical shape throughout the length of said case extending from the narrowest portion of said compartment to the widest portion thereof, said opening of said depression extending substantially less than of said cylindrical shape,
said ballpoint pen cartridge extending in said compartment asymmetrically relative to an axial center line of said cylindrical shape,
said compass point arm being thicker at said end remote from said compass point, and
a transverse pin mounted to said case passing through said axial center line and thereat pivotally mounting said compass point arm.
2. The compass ballpoint pen, as set forth in claim 1,
wherein said compass point arm is completely housed in said depression in the retracted position of said needle,
said depression has a circularly widened portion, and
a grooved wheel means for adjusting the extent of said compass point on said arm and said means received by said circularly widened portion and fits substantially flush with said cylindrical shape of said case.
3. The compass ballpoint pen, as set forth in claim 2,
wherein said case having notches to facilitate the pivoting of said arm, and
a grooved cylindrical pommel means for easing the tracing.
