ABSTRACT:

BACKGROUND
This invention relates generally to the art of dispensing sheet material. More particularly it relates to method, devices and system for dispensing rolled paper products such as paper towels, toilet paper etc.
The Problem
The problem with prior art sheet material dispensing devices and systems is that they are not suitable for hassle free, low cost dispensing of rolled paper.
a) Not hassle free
b) Not integrated into a slim aesthetic portable design.
c) Not cost effective.
d) Limited functionality.
e) Operation requires too much time and skill.
f) Complex with too many moving parts.
g) Do not control precision in dispensing
They either unroll too easily (free spool types) or have difficulties from inadequate restraining and braking force or too much of it.
It is too loose, it can come free and unless you have hand ready to catch it, user would be chasing it on the floor or counter. It requires both hands to tear the sheet material from the roll. It takes a reasonably dexterous and alert person to successfully use the dispensers of the prior art. Prior art devices especially have been a problem for children, handicapped, elderly and a lot of people who are not dexterous enough.
SUMMARY
The rolled paper dispensing system of this invention comprises a cradle in a housing enclosure with easily releasable latch lock. The semi-circular cradle provides a stable storage means that can be located easily. It also gives useful braking from the friction with the rotating roll. The hinge and latch feature make it easy to deploy and retract it to the loading mode or the dispensing mode. The enclosure housing can be mounted on a vertical and horizontal surface. If mounted on a vertical surface, the top makes a handy shelf. The cutting edge guide, combined with the braking drag simplifies tearing rolled paper sheets from the dispenser. The housing enclosure prevents accidental dislodgement and contamination. Prior art dispensers have exposed rolled material. This constitutes a critical difference for some users.
PRIOR ART
A formal prior art search was conducted and furthermore the inventor is intimately familiar with the prior art. Following are typical examples of the prior art arranged in the reverse chronological order for easy reference of the reader.
5) Japanese Patent JP3-63-101249A awarded to Setsu Tanzawa of Ricoh Co Ltd in May 1998 for “Image Recording Device”
4) U.S. Pat. No. 3,494,518 presented to R G Goss on Feb. 10, 1970 for “Ribbon Dispenser”
3) U.S. Pat. No. 2,726,823 bestowed upon R W Jesperson on Dec. 13, 1955 for “Supply Roll Mounting Means for Dispensing Cabinets”
2) U.S. Pat. No. 2,146,038 blessed upon M J West on Feb. 7, 1939 for “Paper Dispensing Cabinet”
1) U.S. Pat. No. 1,502,218 earned by C F Van Hook on Jul. 22, 1924 for “Locking Device for Spools”
None of the prior art devices known to the applicant singly or even in combination disclose the EXACT embodiment of this inventor that constitutes a simple, elegant, quick, convenient, affordable solution for rolled paper dispensing.
The applicant's invention is better for the following reasons:
a) The user is not required to disassemble and assemble hardware to unload and load the rolled material.
b) There are no telescoping rods, rods with movable ends, and stud shafts on spring loaded arms to deal with.
c) The dispenser cabinet completely encloses the rolled material which prevents accidental dislodging and contamination. Finally, with the range of plastic and other materials available to make the dispenser, it can be made attractive, durable, trouble free and affordable.
Discussion of the Prior Art
a) U.S. Pat. No. 3,494,518 shows a roll of ribbon coming forward and down, albeit by a mechanism very unlike the case at bar. Their second embodiment is a more complex version which is tangentially relevant here.
b) U.S. Pat. No. 2,926,823 Arms
