Abstract
The cap of a marking device such as a felt tip marker is attached by a cap retaining device adjacent the body of a user. The barrel or marking portion of the marking device may then be readily removed, used for marking and then reinserted into the cap using only a single hand.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The subject invention relates generally to holders for marking devices and more particularly to apparatus readily adaptable for mounting conventional marking devices adjacent the body of a user, and particularly such marking devices as typically employed in the construction industry.
2. Description of the Related Art
Marking devices are commonly used in many occupations for marking, drawing or writing. Such devices include, for example, felt tip pens, paint pens and artist pens. Construction workers, warehouse workers and postal employees are just a few examples of users of such devices.
Such marking devices typically consist of two parts: (1) a stick, barrel or marker portion having a tip and (2) an airtight cap which snaps or press fits onto the stick portion. They are often carried in a shirt or pants pocket or a tool belt pouch. Typically, before use, the user must locate and pick up the marker, then grip the barrel of the marker in one hand while gripping the cap in the other hand in order to pull the cap off. This procedure leads to a number of problems.
For example, in the case of construction workers, a marker is often used in conjunction with a measuring tape to measure a piece of building material to be cut to a certain size. The worker first applies the tape to the piece of building material. Next, the worker must mark the material for cutting. To mark the material, the worker must remove the marker from his or her pocket or carrying pouch and then remove the cap from the marker. At present, the cap is often removed by placing the marker cap in the worker's mouth, biting the cap, and pulling the marker barrel free, all the while struggling to keep the measuring tape in its proper place with the other hand. The difficulty of executing this maneuver is often compounded by the fact that the worker may be measuring atop a ladder. Moreover, in the course of executing such maneuvers, the cap is often laid aside and lost.
One might suppose that such difficulties could be avoided by removing the cap first before measuring. This approach is not usually practical either, because it is usually necessary to use both hands in order to extract and hook the end of the measuring tape, especially with long measurements.
SUMMARY OF THE INVENTION
According to the invention, apparatus is provided for retaining the cap of a marking device adjacent the body of a user while the marking portion of the device is in use. The present invention facilitates (but does not require) convenient one-handed use of felt-tip and other marking pens.
The invention further contemplates a method of using a marking stick designed to be inserted into a cap comprising the steps of attaching a cap adjacent the body of a user of the stick, inserting the stick into the cap, and withdrawing the stick from the cap when it is desired to use the stick for marking purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art.
FIGS. 1-4
illustrate a first preferred embodiment marker holder
11
for use with a first style marking device
39
. The marking device
39
includes a cap
35
, which typically snaps onto a marking portion or body
37
of the device
39
. Typical of the marking devices
39
which may be retained by the embodiment of
FIGS. 1-4
are the marking devices sold under the trademark “HI-LITER®.”
As shown in
FIG. 1
, the holder device
11
includes a main body piece
13
, a retainer flap
15
and a mounting clip
17
. The main body piece
13
and retainer flap
15
may be fabricated of sturdy fabric, such as leather, cloth or synthetic material, including woven poly or nylon webbing.
The main body piece
13
is folded over at bend
20
to create downturned flap portion
21
. The main body piece
13
is then folded back on itself and suitably cut to create two depending flaps
25
,
26
, defined at their top-most edge by a stitch line
23
. At the stitch line
23
, the downturned portion
21
is stitched to the portion of the main body piece
13
lying behind portion
21
.
As best seen in
FIG. 2
, the folds of the depending flap portions
25
,
26
accommodate respective pivot arms
41
,
43
which are welded or otherwise fixably attached to a metal nut
27
. The nut
27
has a top edge
29
, a bottom edge
31
and is internally threaded as illustrated in FIG.
4
.
The retainer flap
15
is stitched to the main body piece
13
along stitch line
14
and glued elsewhere along its edges to the main body piece
13
. The retainer clip
17
includes a vertical depending portion (not shown) which is sandwiched by the main body piece
13
and retainer flap
15
. All three of these pieces
13
,
15
,
17
are further fastened together by a rivet
19
or other suitable fastener.
In operation, the cap
35
is removed from the body
37
of the marking device and inserted downwardly through the nut
27
to assume the position shown in FIG.
2
. The nut
27
retains the cap
35
.
Since the cap
35
is formed of relatively soft plastic, it may be screwed into the nut
27
in such a fashion that the threads
36
bite into and retain the plastic cap
35
. In this aspect, the threads
36
of the device may be considered as being “self-tapping” and the cap
35
may be said to interlock with the nut
27
. With the cap
35
preferably in the position illustrated in
FIG. 3
, the body
37
of the marking device
39
is then snap-fitted back into cap
35
and is ready for use.
When it is desired to use the marking device
39
, the marking portion of the device
37
may be extracted by pulling it vertically downward in the direction of the arrow
40
(
FIG. 2
) to expose the tip of the marking portion
37
of the device
39
. When use of the marking portion
37
is complete the marking portion
37
is simply reinserted by snapping it into the cap
35
which still remains attached to nut
27
. Such reinsertion may best be accomplished when the cap
35
is in the position shown in FIG.
3
. It will be apparent that the marking portion
37
can be extracted for use in the downward position shown in
FIG. 2
or at any desired angle between the downward position of FIG.
2
and the vertical position of
FIG. 3
, if desired. The nut
27
may also have a funnel-shaped (conically tapered) threaded interior. Such an interior may more suitably accommodate caps
35
which are wider at the top than the bottom and can be inverted to accommodate caps which are narrower at the top than at the bottom.
It may be noted that the flexible nature of the fabric employed in fabrication of the preferred embodiment permits the marking device to move sidewardly in the direction of either of the arrows
42
or
44
in FIG.
2
. Such sideward flexibility can also be provided by pivotally mounting the cap or cap-retaining component to pivot sidewardly, i.e., clockwise or counterclockwise. For example, pivot arms
41
,
43
can be attached to a plate, which is in turn pivotally mounted to the clip
17
. Sideward flexibility together with the pivotal nature of the mounting of the nut
27
permits the device to be clipped to a belt via clip
17
and to then adapt to user movements, for example, to move from one side to the other when the user sits down. Another advantage is that the extended or apron portion
45
of the main body piece
13
provides protection against marking of the user's pants when the marking portion
37
is being extracted.
If desired, a simpler embodiment can be provided wherein only a clip
17
, an apron portion, and a cap mounting/retaining device are employed. In such an embodiment, the apron may be a piece of material having a top edge attached to a rivet such as rivet
19
and a cap retaining device attached directly to the clip
17
.
It may be further noted that the cap portion
35
could be a permanent metallic piece attached to the nut
27
or formed as a unitary part thereof, in which case multiple body portions
37
could be inserted into such a cap portion with their conventional plastic cap being discarded. Furthermore, while
FIGS. 1-4
illustrate a marker holder apparatus which is particularly suited to be clipped to a belt, it should be appreciated that suitable or equivalent components of the disclosed marker holder apparatus could also be formed as part of a tool belt or tool pouch such as conventionally worn about the waist of various tradesmen.
FIG. 5
illustrates a second embodiment for use with a second type of marking device. This embodiment employs a sleeve
59
having a ring
61
pivotally mounted with respect thereto. This sleeve
59
may be attached, if desired, to a clip such as clip
17
in
FIG. 1
by welding or by other attachment means. The ring
61
is inserted into a second ring
63
, which is fixably attached by welding or other means to a nut
65
. The insertion of ring
61
through ring
63
provides pivotal motion of the nut
65
in and out of the page.
The nut
65
is particularly adapted to retain the cap
51
of the second style marking device. This cap
51
is shown in FIG.
6
and includes an outer circular rim
53
and an inner plug
55
having a circular perimeter. A gap of annular cross section is defined between the inner perimeter of the rim
51
and outer perimeter of the plug
55
. The nut
65
sized to fit into this annular opening and preferably carries internal threads, which cut into and interlock with the inner plug
55
in self-tapping fashion.
An embodiment can be made that does not have a second ring (item
63
). Instead, an enlarged hole is drilled in the nut
65
. Also, instead of sleeve
59
, a variation of ring
61
is attached directly to the clip
17
at 90°. This configuration is a much simpler design which achieves the same result as the one in FIG.
5
. Up and down flexibility is provided the same way as
FIG. 5
with the side to side movement provided by the enlarged hole through nut
65
as well as the inherent flexibility provided by the clip to belt mount. An advantage of this design is that it holds the cap over the marker guard flap, whereas the style in
FIG. 5
is a bit floppy.
FIG. 7
illustrates an alternate embodiment for use with the second style marking device. This alternate embodiment differs from that of
FIG. 5
in that the nut
65
is provided with two pivot arms
141
,
143
which are inserted into adjacent flaps
125
,
126
in the manner shown and discussed with respect to FIG.
2
.
FIG. 8
illustrates an alternate embodiment suitable for use with marking devices like device
39
illustrated in FIG.
2
. This embodiment employs a “Chinese finger clamp”
71
to retain a marking device cap. Opposite ends of a pivot arm
75
are retained by respective flaps
25
,
26
. The finger clamp
71
is of such a nature that, if the cap
35
is twisted and pushed into it in one direction, the cap
35
becomes firmly gripped by the clamp
71
, whereas, if the cap
35
is twisted in the same direction, and pulled out, it readily releases from the clamp
71
.
FIGS. 9-11
illustrate apparatus for retaining the mounting cap of a third style marker
101
. The cap
83
of this third marking device
101
is conically tapered and rounded to a top most edge
84
and has a clip
85
mounted to its side face.
The cap
83
is received and grasped by a special retainer
87
best illustrated in FIG.
10
. This retainer
87
includes parallel, vertically depending side legs
93
,
95
and horizontal arms
88
,
89
extending from the legs
93
,
95
. At the top of the retainer
87
, the legs
93
form into a U-shaped portion having downwardly depending arms
90
,
92
attached by a cross piece
91
.
To insert the cap
83
of the marking device
101
into the retainer
87
, the cap
83
is inverted as shown in FIG.
11
and the clip
85
is inserted into the gap
94
between the respective arms
90
,
92
. The cap
83
is then rotated clockwise in the direction of the arrow
98
in order to reach the position shown in FIG.
9
. The marking portion
100
of the device
101
may then be extracted from the cap for marking purposes by pulling it downwardly in the direction of the arrow
103
.
FIGS. 12-14
illustrate another embodiment useful, for example, with the third style marker, e.g.,
101
. This embodiment employs arcuately shaped clip arms
161
,
163
, a barrel guide
165
, and a pen clip receiver slot
167
, all integrally formed with a vertically disposed back portion
169
. Rivet holes
170
may be provided to facilitate attachment to a belt, pouch, apron or other surface, if desired. Various other attachment mechanisms, such as those illustrated herein, are of course applicable. The embodiment of
FIGS. 12-14
is preferably made of metal, such as, for example, spring steel.
The barrel guide
165
provides a cylindrical opening
171
split into two halves along split
173
. The barrel guide
165
provides support to the barrel, e.g.
100
, of a marking device to assist in preventing inadvertent unclipping of the cap, e.g.,
83
. The barrel guide
165
may be omitted in various embodiments. The length “l” of the receiver slot
167
is preferably selected to accommodate various cap shapes of commercially available markers.
The embodiments of
FIGS. 1-8
provide a number of examples directed to retaining marker caps without built-in clips. These and other alternate embodiments may be described as follows:
1. Self-tapping nut. This form of attachment utilizes a machine-threaded nut that self taps onto a plastic marker cap. The threads of the nut may tap onto the outside or inside of the marker cap, depending on the particular type or brand of cap being attached. It is possible to make a multiple threaded holder to accommodate more than one brand of marker. For example, two different thread diameters may be provided, one on each end of the nut. This configuration allows the same holder to attach either Dixon or Sanford brand marks as well as many others with the same diameter cap. The outside of the holder nut may also be threaded in order to create a single holder to fit even more brands of caps. Also, a slight taper to the threads may ease tapping as well as accommodate more brands of markers. Most marker cap's inside nib cover (the round part inside the outer grip portion) are very close in diameter. Of course, pre-threaded caps may also be provided.
2. Chinese finger trap style, e.g. FIG.
7
.
3. A buckle style clamp
121
such as illustrated in
FIG. 15
applied around the outside circumference of a cap, e.g.
123
. Such a clamp can be made adjustable to accommodate different size caps. These style clamps are common; most fire extinguishers attach to a wall bracket with such a clamp.
4. Hose clamp style and other releasable clasp styles also could fit a wide range of circumferences.
5. Encapsulated cap wherein a particular shape of cap is either partially or wholly encapsulated by a suitably shaped holder. Such an encapsulation can constitute a mated counter part into which the cap is inserted. The mated counterpart is so designed so that when the cap is fully inserted it is retained by structural features of the encapsulation device. For example, during insertion, the cap may push aside one or more flexible clips. Such a clip or clips, upon full insertion, snap over the end of the cap thereby holding the cap within the encapsulation. To remove the cap from such an encapsulation one simply pushes aside the clip or clips, thus freeing the cap for removal.
The encapsulation can contain a funnel-shaped entrance at the cap opening included in its design to ease reinsertion of the marker barrel. Such a funnel shape can also aid in securing the marker barrel against accidental dislodging. Such an encapsulation can be made of one or more pieces of molded plastic or can also be made of metal or other suitable material, or a combination thereof. Other means of encapsulation are possible and readily apparent to anyone skilled in the art. An encapsulation employing halves
135
,
137
as shown in
FIG. 16
, would snap together, thus firmly holding the cap, e.g.
139
, in place. As noted, such an encapsulation could include a funnel-shaped entrance in order to make it easier to replace the marker back into the holder.
6. Cap pre manufactured with one hole through the outer shell grip portion. This configuration would allow for the cap to be inserted into a socket of suitable material. A hole in the socket would then be aligned with the hole in the cap allowing the insertion of a snap or screw in order to firmly secure the cap to the socket holder.
7. A cap, such as cap
141
of
FIG. 17
, made with two opposing holes or indentations as
143
,
145
. One way of attachment is the use of a C-clip
147
. The cap
141
accepts the two inwardly projecting ends
149
,
151
of the clip
147
, thus securing the cap
141
. Another possibility, utilizing two opposing holes, would require the cap to be made with the outer shell slightly longer with two opposing holes in the lengthened portion. A rod would then be inserted through the cap.
8. Pre-molded cap with depressions or protruding clips. Either of these configurations would allow the cap to be snapped directly to a mated counterpart.
9. Permanent durable cap made of high quality durable material such as metal or other suitable material. Such a cap would be permanently or removably attached to holder. With plastic barreled markers the entire cap could be made of such material. (The plastic of the barrel provides the sealing means). Metal barreled markers would require the addition of an O-ring seal made of a suitable long lasting material such as nylon, for example.
10. One-piece plastic molded cap
160
, belt-clip
167
, and mark-guard
161
all in one, such as illustrated in
FIG. 18. A
plastic hinge
168
, molded just below the clip
167
may optionally be provided for flexibility. Plastic forming and molding techniques may be applied to simplify and reduce part count and cost of various embodiments disclosed herein and variations thereof.
11.
FIG. 19
illustrates employment of a fabric hinge or hinges as one of many possible attachment mechanisms for mounting a cap-retaining mechanism to a tool belt or apron. Other mechanisms include stiff metal or plastic protruding hinges or rings suitably attached at their base directly to the tool apron or other article of wear. Up and down movement would be provided in the same way as in the many embodiments previously described. Sideways flexibility would be inherently provided by the flexibility of the article of wear itself.
Those skilled in the art will appreciate from the many illustrative embodiments disclosed above that various adaptations and modifications of the just-described preferred embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
