Writing Instrument Holding Clip for Retractable Tape

1. Field of the Invention

The present invention relates to clips used to releasably attach a retractable (sometimes also referred to as coilable or recoilable) tape measure to a user's clothing, and more particularly to clips for retractable tape measures having structural provision for selectively receiving a writing instrument, as for example a pencil.

2. Description of the Prior Art

Retractable tape measures have become an indispensable tool of tradespeople because of their inherent compactness, ease of use and accuracy of the provided measurement. Retractable tape measures include a case; a flexible, elongated blade upon which distance measurements are printed; a hook end typically having a special slot therein which allows a nail to serve as a pivot for drawing circles measured therefrom; a spring rewinding mechanism for retracting the blade via biased spooling thereof; a release button for selectively actuating the rewinding mechanism when the blade is extended; and a clip connected to a side of the case for clipping the case onto an article of clothing of the user, such as for example a belt.

One of the most frequent uses of a retractable tape measure is to measure a distance across an object, such as a board or sheet of building material, in preparation for its being cut or otherwise acted upon. In order for the user to remember the exact location of the measured spot, it is necessary to leave a mark on the surface of the object at the spot, usually via a writing instrument such as a pencil, pen, marker or crayon. However, since it is so easy to have accidentally placed a writing instrument out of reach when the measurement is taken, the measurement has to be repeated with the writing instrument in hand.

Further, as alluded to hereinabove, retractable tape measures may be used to draw circles on the surface of an object whereby a nail head forms the radial center, the special slot of the hook end of the blade engages the nail head, and the blade serves as a radius of various lengths. In order to provide a circle mark as accurate as possible, the user must try to hold the case and a writing instrument against the case as the case is arcingly moved about the nail head center pivot. Frequently, the actual result is not only radially inaccurate, but also the circumference is drawn unsteady (ie., wavy, somewhat sawtooth-locking) rather than drawn smoothly, especially if the surface grain is rough.

Accordingly, it would be most beneficial if somehow a writing instrument could be removably attached to a retractable tape measure so that the writing instrument is always present to mark the spot whenever a measurement is made, and further so that the writing instrument is located relative to the case so that accurate arcs can be drawn with respect to a nail head centerpoint.

The present invention is a clip for a retractable tape measure which is structured to seatably receive a writing instrument so that the writing instrument is always present to mark the spot whenever a measurement is to be made, and further so that the writing instrument is located relative to the case so that accurate arcs can be drawn with respect to a nail head (or other analogous protruding structure).

The clip according to the present invention includes a clip body composed of a base member for being anchored fastenably to the case of a retractable tape measure and a spring member integrally connected with the base member for resiliently yielding when an article is slipped between the base and spring members. The clip further includes a writing instrument holder associated with the clip body for removably receiving a writing instrument. The preferred clip is constructed of high yield spring type stainless steel sheet material, wherein the clip body and the writing instrument holder are integrally formed in a single piece.

In a first preferred embodiment of the clip according to the present invention, the clip body includes a base member shaped to seat (form fit) into a recess formed in the exterior of the rear side of the case of the retractable tape measure. The base member has an affixing hole for a threaded fastener to connect it to the case. The spring member is formed of an inboard portion of the clip body which is looped via an arcuate bend so as to generally adjacently overlap, and be resiliently biased toward, the base member. The writing instrument holder is formed of outboard portions (one on either side of the inboard portion) of the clip body which are bent into arcuate fingers adjacent the arcuate bend. It is preferred for the clip to be orientable in either of two perpendicular directions relative to the case.

In a second preferred embodiment of the clip according to the present invention, the clip body includes a base member shaped to seat (form fit) into a recess formed in the exterior of the rear side of the case of the retractable tape measure. The base member has an affixing hole for a threaded fastener to connect it to the case. The spring member is formed of the clip body by its being looped via an arcuate bend so as to generally adjacently overlap, and be resiliently biased toward, the base member. The writing instrument holder is formed of the spring member having a medial aperture and a centrally located slot in the arcuate bend that connects with the medial aperture. A writing instrument is disposed adjoining the base member by being placed into the slot and medial aperture and between the base member and the spring member at its distal end.

In a third embodiment of a clip according to the present invention, the writing instrument holders of the first and second preferred embodiments are included.

In a fourth embodiment of the clip according to the present invention, a conventional clip for a retractable tape measure is utilized in conjunction with a writing instrument holder which is connected with the case, wherein the writing instrument holder is in the form of arcuate fingers adjacent the arcuate bend of the clip.

In operation, the clip according to the present invention serves as an article clipping device in a conventional manner, wherein an article of the user's clothing is resiliently held between the spring and base members so as to selectively attach the case of the retractable tape measure to the clothing of the user. Further, the clip according to the present invention selectively holds a writing instrument which has been thrust axially into the writing instrument holder. In the event an arc is to be drawn with respect to a nail head via the hook end of the retractable tape measure, the writing instrument holder securely holds the writing instrument with respect to the case so that the resulting drawn circumference is both accurate and smooth. The advantage of the first, third and fourth preferred embodiments of the clip according to the present invention is that the spring member and the writing instrument holder are able to operate independently, so that a writing instrument may be received while the clip is simultaneously engaged with an article of clothing.

Accordingly, it is an object of the present invention to provide a clip which has provision for releasably holding a writing instrument.

It is an additional object of the present invention to provide a clip for a retractable tape measure, wherein the clip functions to attach the retractable tape measure to an article of clothing of the user and further functions simultaneously to releasably retain a writing instrument.

It is another object of the present invention to provide a clip for a retractable tape measure which provides location for a writing instrument with respect to the case of the retractable tape measure when the retractable tape measure is being used to draw a circumference.

It is a further object of the present invention to provide retractable tape measure, wherein the clip thereof is positionable in selected orientations, preferably in mutually perpendicular orientations.

It is yet a further object of the present invention to provide a writing instrument holder for retrofitting with a conventional clip of a retractable tape measure or another object.

FIG. 11 is a side view of a writing instrument holder according to the present invention equipped with a writing instrument point protector.

Referring now to the Drawing, a clip 10 according to a first embodiment of the present invention is shown by FIGS. 1 through 6. The clip 10 is attached to the rear side 12a of the case 12 of a retractable tape measure 14 via, for example, a threaded fastener 16. The clip 10 serves to clippingly hold the retractable tape measure 14 to an article of the user's clothing, such as for example a belt, and further serves to releasably hold a writing instrument, such as for example a pen, pencil, crayon or marker, proximate the case 12.

The clip 10 includes a clip body 18 having a base member 20 and a spring member 22, preferably formed of a single piece of sheet stock, where the sheet stock is preferred to be a spring type stainless steel. The base member 20 is structured to be affixed to the rear side 12a of the case 12. The spring member 22 is formed by an arcuate bend 30 formed in an inboard portion 18a of the clip body 18 commencing at the base member 20, wherein the spring member is looped back so as to be resiliently biased against the base member. The spring member 22 is preferred to have an outwardly curved distal end 22a for facilitating slipping an article, such as a user's belt, between the spring member and the base member. In this regard, the clip body 18 serves to clippingly attach the case 12 to an article of clothing of the user, such as a belt, via resilient biasing vis-a-vis the base and spring members 20, 22 when the article is slid therebetween. The base member includes an affixing hole 20a through which the threaded fastener 16 extends and then threadably fastens to the case 12.

The clip 10 further includes a writing instrument holder 24 integrally connected with the clip body 18. The writing instrument holder 24 is formed by an outboard portion 18b of the clip body 18 being curvably bent to thereby form two spaced apart arcuate fingers 26a, 26b located adjacent the arcuate bend 30 of the clip body 18. It is to be understood that while the writing instrument holder 24 is preferred to be integrally connected with the clip body 18, this is not a requirement. The convex surface of the arcuate bend 30, the concave surface of each of the arcuate fingers 26a, 26b and the immediately adjacent surface of the rear side 12a of the case 12 collectively form a receptacle 32 (as best shown by FIG. 3) for receiving a writing instrument 28 by the writing instrument being axially slid thereinto. With respect to facilitating sliding of the writing instrument 28 into the receptacle 32, a bevel 34 is provided at each end of the arcuate bend 30 (see FIGS. 2 and 3). Thus, as a user begins to insert the writing instrument axially into the receptacle 32, the bevels 34 guide entry of the writing instrument 28 and further serve to save the surface of the writing instrument from being scarred, as would otherwise occur as the writing instrument scraped against an end of the arcuate bend 30.

The rear side 12a of the case 12 is preferably provided with a recess into which the base member 20 of the clip body 18 seats. As depicted by FIG. 6, it is preferred for the recess 36 to have a bidirectional pattern, whereby the base member 20 is seatable selectably in either of two mutually perpendicular orientations relative to the case 12, as shown in FIGS. 4 and 5. That is, when the base member 20 seats in a first portion 36a of the recess 36, the clip 10 is oriented at a first orientation relative to the case 12 as shown in FIG. 4; and when the base member seats in a second portion 36b of the recess, the clip is oriented at a second orientation relative to the case as shown in FIG. 5. An advantage of the base member 20 being seated in the first portion 36a of the recess 36, whereby the clip 10 is oriented in the first orientation as shown in FIG. 1, is that the writing instrument 28 is in ready position to draw a circumference line 46.

In operation, a user uses the clip body 18 to clippably attach the case 12 to an article of the user's clothing in a conventional manner. The user slips, axially, a writing instrument 28 into the receptacle 32 formed between the arcuate fingers 26a, 26b, the arcuate bend 30 and the surface 12a of the case 12 to thereby hold the writing instrument to the casing 12. In this regard, FIG. 1 depicts an example of operation wherein the special slot 38a of the hook end 38 of the blade 40 of the retractable tape measure 14 engaged with a nail head 42, wherein a circle circumference is desired to be drawn on the surface 44a of an object 44. The writing instrument 28 is located fixedly with respect to the case 12 so that as the user moves the case arcingly about the nail head 42, the writing instrument provides a smooth and accurately radiused circumferential line 46.

Referring now additionally to FIGS. 7 and 8, a second preferred embodiment of the clip 10' will be detailed.
