Abstract
In combination with a toilet paper dispenser having a base mountable upon a wall and a pair of opposed trunnion arms removably mounting a dowel which loosely journals a roll of toilet paper having a lead sheet. The improvement comprises in combination therewith a biasing means for restraining unwinding of the roll, including a cover projecting from the wall and overlying the roll. A mount strip of resilient material is secured to the cover and includes a depending hinge secured to the wall.

Description
Background of the Invention
Heretofore there has existed the problem in the mounting of a roll of toilet paper upon a bracket dispenser and of providing some means for restraining the roll against unlimited unwinding. In the environment of a dispenser having a base mountable upon a wall and a pair of opposed trunnion arms removably mounting a dowel which loosely journals a roll of toilet paper having a lead sheet, since the roll is loosely mounted upon the dowel there is the need for some means for restraining the roll during unwinding thereof
In the prior art it has been known to frictionally mount the roll of toilet paper upon the dowel and in turn frictionally and restrainingly mount the dowel within the dispenser bracket such that there is a bias against free rotation of the dowel itself.
Illustrative of this in the prior art are the following U.S. Pat. Nos.
Further illustrative in the prior art of devices for restraining the unwinding of a roll of material, particularly by usage of restraint or biasing device against the roll holder and with the roll normally mounted snuggly upon the roll holder are the following further U.S. Pat. Nos.
Prior art efforts to restrain the unwinding of a spool of strip material were primarily directed therefore to means for restraining rotation of the spool support in various ways.
Summary of the Invention
It is an important feature of the present invention that in conjunction with a toilet paper dispenser having a base mountable upon a wall and a pair of opposed trunnion arms removably mounting a dowel which loosely journals and supports a roll of toilet paper having a lead sheet, there is provided in combination therewith a biasing means which restrains unwinding of the roll itself, and wherein the restraining means frictionally and yieldably engages the roll tangentially during unwinding thereof.
It is a further feature of the present invention to provide in conjunction with said such dispenser a cover which overlies the roll of toilet paper. A biasing means is employed for restraining unwinding of the roll which includes a cover projecting from the wall which overlies and partly encloses the roll and has front and rear edges. An elongated mount strip of resilient material is secured to the cover at its rear edge and includes an elongated depending hinge strip flexibly connected to and depending from the mount strip and secured to the wall or to the bracket. A friction tab is arranged on and flexibly and resiliently connected to the mount strip and extends angularly and forwardly downward and is adapted to tangentially and yieldably engage the roll, thereby restraining the roll and lead sheet for limited and controlled unwinding movements.
A further feature includes the construction of the mount strip including its hinge strip and friction tab of a resilient material such that as the roll unwinds and becomes reduced in diameter, friction tab yieldably follows and cooperatively and retainingly engages the roll tangentially thereof until the roll is fully unwound, and during that period limits and controls unwinding of the sheet or strip therefrom.
These and other objects will be seen from the following specification and claims in conjunction with the appended drawing.
The Drawing
FIG. 1 is a side elevational view of the biasing means for restraining unwinding of a roll of toilet paper mounted upon a wall, fragmentarily shown by a conventional dispenser.
FIG. 2 is a vertical section thereof showing the roll partly unwound.
FIG. 3 is a front elevational view thereof, partly in section.
It will be understood that the above drawing illustrates one embodiment of the invention for illustration, and that other embodiments are contemplated within the scope of the claims hereafter set forth.
Detailed Description of an Embodiment of the Invention
Referring to the drawing, conventional type of toilet paper dispenser is generally indicated at 11 as having a bracket 13 which includes a base 15 and at the ends thereof a pair of opposed trunnion arms 17. Often times the bracket is of a plastic material and is secured to the wall W by a plurality of fasteners such as the screws 19, shown in FIGS. 1 and 3.
A conventional roll holding dowel 21 is shown interposed between the outer end portions of the respective trunnions with its ends respectively nested within opposed recesses 29 within said trunnions in a conventional manner. As is characteristic of many dowels of this type, at one end thereof there is a retractable spring biased center 23 which yieldably nests within one of the trunnion recesses to provide a means of conveniently removing the dowel from the trunnion arms normally to facilitate assembly thereon or removal therefrom of a paper roll R in a conventional manner.
The roll in the present case includes a cylindrical core 25 which is loosely mounted upon said dowel and thus free for rotation thereof including the lead sheet 27 which projects from the windings of tissue upon and forming a part of said roll. The present improvement contemplates in combination with such toilet paper dispenser of a biasing means for restraining unwinding of the roll by direct engagement with the roll itself. The present biasing means is in the nature of a cover 31 or hood, generally semi-cylindrical in shape which has an arcuate top wall 33, front and rear edges and a pair of upright spaced end walls 35.
The cover or hood projects outwardly from the wall W, overlies and partly encloses the roll R.
The biasing means includes a resilient mounting for the cover or the hood which is in the form of an elongated mount strip 37, preferably constructed of a corrugated plastic, but resilient material. In the illustrative embodiment, the mount strip at its upper portion overlies the interior rear edge portion of the arcuate wall 33 and is secured thereto as by a pair of fasteners such as staples 39. Any other suitable fastening means may be employed such as adhesive for illustration.
Intermediate the top and bottom of the mount strip there is a crease 41 or scoring defining therebelow an elongated hinge strip 43 with said strip suitably secured to the wall, and indirectly in the illustrative embodiment secured by adhesive 45 to a portion of the bracket base 15. Any other type of conventional fastening means may be employed for anchoring the hinge strip to the wall W or to the base 15.
The mount strip at its upper edge has a further fold line or hinge 49 which defines the elongated friction tab 47 which extends downwardly and forwardly, as shown in FIG. 2. Said friction tab is adapted to operatively and yieldingly bear against roll R tangentially thereof as well as against the depending lead sheet 27 for the purpose of restraining free unwinding movements of the roll and thereby permitting a controlled unwinding thereof.
The tab 47 is resiliently connected to mount strip 37 and due to this resiliency is at all times biased against the outer surface of the roll R during unwinding thereof and as the roll becomes gradually reduced in diameter, such as shown in FIG. 2. The construction of the tab as associated with the mount strip is of such resiliency that the tab at all times is biased against the roll R tangentially thereto at 51 to provide controlled unwinding of the roll, FIG. 2.
The present cover or hood 31 may be constructed of plastic or of stiff paper, for example, and as initially assembled, will have its lower edge substantially horizontally disposed, FIG. 1, so as to enclose merely the upper portion of the roll of tissue.
As the roll is reduced in diameter due to continued use, and with the tab being continually biased against its outer surface, as the roll unwinds, the hood or cover will gradually move upwardly such as to the dash line position shown in FIG. 2. This has the advantage of facilitating the disassembly of the used roll of toilet paper, the insertion of a new roll, such as shown in FIG. 1.
Having described my invention, reference should now be had to the following claims.
Claims
I claim:
