Marker pen holder

1. A device for supporting and holding a marker having a protective mating marker cap, the cap having a pocket attachment clip spaced from and extending longitudinally along an exterior surface of the marker cap, the device comprising:

a main body having a longitudinally extending receiving cavity consisting of a principal cavity portion adapted to accommodate said marker cap therein and an auxiliary cavity portion adapted for at least partially receiving said pocket attachment clip; and

an attachment clip-retention arrangement for resealably retaining the marker cap within said cavity, said attachment clip-retention arrangement having at least one aperture formed within said body and adapted to accommodate at least one securing member, said at least one aperture having a central axis positioned at an angle to longitudinal axes of said principal and auxiliary cavity portions.

2. A device as recited in claim 1 , wherein the auxiliary cavity portion further comprises a longitudinally extending channel sized and shaped for capturing the marker cap pocket attachment clip in a manner limiting rotation of the marker cap about its longitudinal axis and maintaining the cap in a predetermined desired orientation.

3. A device as recited in claim 1 , wherein said cap retention arrangement further comprises a resilient insert at least partially covering said receiving cavity and configured for frictionally engaging the marker cap.

4. A device as recited in claim 3 , wherein said resilient insert further comprises an upper lip configured for extending over an edge surrounding a marker-receiving opening of said marker cap body.

5. A device as recited in claim 1 , wherein said main body further comprises first and second main structural body portions configured for releasable attachment to each other.

6. A device as recited in claim 5 , wherein said first and second main body portions further comprise cooperating snap fit structures for enabling said releasable attachment.

7. A device as recited in claim 1 , further comprising attachment arrangement for fixedly attaching the main body to a support surface, said attachment means further includes means for securing said main body to a supporting surface.

8. A device as recited in claim 7 , wherein said attachment arrangement further comprises at least one mechanical fastener extending through an aperture in a sidewall of said main body.

9. A device as recited in claim 7 , wherein said attachment means further comprises an adhesive disposed on an exterior surface of said main body.

10. A device as recited in claim 1 , wherein said main body includes at least one side wall and said securing member is a securing pin extending through said at least one aperture formed within said at least one side wall.

11. A device as recited in claim 10 , wherein said securing pin traverses a space between the exterior marker cap body surface and the pocket attachment clip.

12. A device as recited in claim 10 , further comprising an arrangement for positional adjustment of said pin along the longitudinal axis of said principal cavity.

13. A device as recited in claim 12 , wherein said positional adjustment arrangement further comprises a series of corresponding aligned aperture pairs provided in opposite side walls of said main body, each said aligned pair of apertures configured for receiving said securing pin therethrough.

14. A device for supporting and holding a marker having a protective mating cap having an exterior body surface and a pocket attachment clip spaced from and extending longitudinally along the exterior body surface, the device comprising:

a main body formed with a principal cavity portion adapted to accommodate the protective cap therein and an auxiliary cavity portion adapted for at least partially receiving the pocket attachment clip; and

a securing member extending through said main body and traversing a space between the exterior body surface and the pocket attachment clip, so as to removably secure said cap within said main body to enable one-handed removal and insertion of the marker into and from the protective cap.

15. A device as recited in claim 14 , wherein said securing member is a securing pin, and said main body further comprises at least one sidewall having at least one aperture extending therethrough, said at least one aperture having a central axis positioned at an angle to the longitudinal axes of said principal and auxiliary cavities.

16. A device as recited in claim 15 , further comprising attachment arrangement for attaching the main body to a support surface.

17. A device for supporting and holding at least one marker having a protective mating cap including a pocket attachment clip on the exterior of a cap body, the device comprising:

a front body;

a rear body;

clamping arrangement adjustably securing said front body to said rear body;

said front and rear bodies cooperating to define at least one receiving cavity adapted for receiving the protective cap therebetween;

said at least one receiving cavity comprises a principal cavity portion for receiving said cap body and an auxiliary cavity portion for receiving said marker cap pocket attachment clip;

resilient means at least partially lining said cavity for frictionally engaging said mating cap; and

said resilient means further comprises a lip portion configured for partially extending over an upper edge surrounding a marker-receiving opening of said cap body.

18. A device as recited in claim 17 , wherein said clamping arrangement further comprising:

a clamping member engaging a rear surface of said rear body; and

a mechanical fastener extending through aligned clearance apertures in said front and rear bodies and having a distal end threadingly engaging a tapped boss portion of said clamping member.

19. A device as recited in claim 17 , further comprising an attachment arrangement for attaching said device to a supporting surface, said attachment arrangement further comprises a clip portion extending from a rear surface of a clamping member.

20. A device as recited in claim 17 , wherein said at least one marker comprises a plurality of markers and said front and rear bodies cooperating to define a plurality of receiving cavities adapted for receiving a plurality of protective caps, said resilient means at least partially lining said cavities for frictionally engaging said mating caps.
