DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 is a back view of one example embodiment of a base and rod mechanism of a toilet paper roll holder 10. Holder 10 includes a base 20 that pivotally supports an arm or rod 24 such that the rod 24 may rotate in a direction, such as a downward direction 52, about a pivot axis 54 when a force is applied in a direction, such as a downward direction 56, on rod 24. Rod may be biased to pivot upwardly in a direction 58 when force in downwardly direction 56 is removed, such that the rod 24 returns to its unbiased horizontal position shown in FIG. 1. In some embodiments the rod 24 may be returned to its unbiased position by application of a manual force in an upward direction 58. Holder 10 may be manufactured such that the amount of force in downward direction 56 that will result in pivoting movement of rod 24 will be slightly greater than the weight of a roll of toilet paper 26 (FIG. 4). In this manner holder 10 will hold a roll of toilet paper 26 on rod 24 but when a greater force is applied to rod 24 the rod will “give way” or pivot downwardly such that rod 24 may not be utilized to secure a ligature thereto.
FIG. 2 is a cross sectional side view of the mechanism of FIG. 1 taken along lines A-A of FIG. 1.
FIG. 3 is a side view of the mechanism of FIG. 1. Base 20 includes a top surface 20 a that is positioned at an angle 20 b in a range of approximately five to twenty degrees, and more particularly, 15 degrees, with respect to a bottom surface 20 c of base 20, wherein bottom surface 20 c of base 20 may be mounted on a mounting plate of a housing 12 (FIG. 4) or may be mounted directly to a mounting surface such as a wall. The inclined position of top surface 20 a with respect to bottom surface 20 c allows for a streamlined profile of top surface 34 or head of spindle 22 and also provides for a smooth downward pivoting motion of spindle 22 about its pivot axis 54 (FIG. 2), which is positioned perpendicular to top surface 20 a of base 20.
Base 20 also defines an angle 20 d that is approximately fifty to seventy degrees, and more particularly, fifty nine degrees. This angle 20 d will cause a ligature to slip over the tapered base and down onto the rod, and thereafter to slide off the rod by triggering the breakaway function, i.e., pivoting, of the rod. In other words, this angle 20 d will hinder a ligature from becoming secured to the taped base.
FIG. 4 is a left side elevational view of one example embodiment of a toilet paper roll holder 10 wherein rod 24 supports roll of paper 26. Roll 26 is covered on its upper surface by an upper portion 12 a of housing 12 and a wall mounting region 12 b of housing 12 including a mounting plate 90 that supports base 20 thereon.
FIG. 5 is a front view of the holder 10 of FIG. 4.
FIG. 6 is an exploded view of the holder 10 of FIG. 4. Holder 10 includes a housing 12, a spindle retaining detent screw 14, a fastener 16, a detent spring 18, a base 20, a spindle 22, a detent 23, and a rod 24. A standard roll of toilet paper 26 may be placed on rod 24. Holder 10 includes many safety features. For example, the sloped upper surface 28 of upper region 12 a of solid housing 12 hinders securement of a ligature thereto and also hinders access to base 20 and rod 24 for securement of a ligature thereto. In the embodiment shown in FIG. 16, the housing 12 includes enclosed side regions 30 that further inhibit securement of a ligature to the housing 12, to base 20 or to rod 24 of the holder 10. Base 20 may be mounted on a mounting plate 90 wherein fasteners 92 may extend through the mounting plate 90 and housing 12 to secure holder 10 to a mounting surface such as a wall. Spindle 22 may be manufactured of aluminum whereas detent 23 may be manufactured of steel to increase the durability of the system as spring 18 rides on detent 23.
Holder 10 also includes the safety feature of a base 20 that includes a smooth, sloped side surface 32 in the general shape of a truncated cone such that a ligature, such as a rope, a wire, hair, a bed sheet or the like, may not be secured thereto. Spindle 22 includes a rounded top surface 34 that inhibits securement of a ligature thereto. An outer surface 36 of rod 24 defines a tapered truncated cone such that the outer diameter 36 a of rod 24 decreases as the diameter measurement point moves away from spindle 22 such that the tapered outer shape 36 of rod 24 inhibits securement of a ligature thereto. In other words, a person could not tie a ligature around rod 24 and pull downwardly without the ligature slipping off rod 24 due to the tapered, sloping outer surface 36 of rod 24, and due to the pivoting structure of rod 24 mounted on base 20, which will be discussed in more detail below.
Holder 10 further includes a safety feature wherein rod 24 “drops”, i.e., will not support a load having a weight significantly greater than the weight of a roll of toilet paper. For example, in one embodiment, the rod will not support a weight of approximately twenty pounds applied to the rod near the base and a weight of approximately two pounds applied to the rod near the tip of the rod. However, in other embodiments the rod will not support a much smaller weight such as approximately half a pound. The structure of spring 18 and detent 23 may determine the exact weight at which the rod rotates in each particular embodiment, wherein spindle 22 with rod 24 secured therein, will rotate within base 20 when a load is applied to the rod 24. As shown in FIGS. 1 and 2, in operation, fastener 16 secures detent spring 18 to base 20. An end 38 of spindle 22 the detent 23 is positioned between first and second arms 40 and 42 of spring 18. End 38 of spindle 22, namely, detent 23, includes two flat regions 44 and 46 (FIG. 11) and two rounded regions 48 and 50 (FIG. 11). The flat regions 44 and 46 define a distance 45 there between that is less than a distance 49 between two rounded regions 48 and 50. In an unbiased condition, with the rod 24 in a horizontal position, the flat regions 44 and 46 of spindle 22 will contact spring 18. As a downward force is brought into contact with rod 24, detent spring will hold spindle 22 in place by contact at flat regions 44 and 46 of detent 23. However, as the force on rod 24 increases, such as to five pounds of force or more applied at the end of rod 24 or approximately twenty pounds of force applied to the rod 24 near base 20, the biasing force of spring 18 will be overcome by the force on rod 24 and arms 40 and 42 of spring 18 will spread apart, thereby allowing spindle 22 to rotate such that curved or rounded regions 48 and 50 will be in contact with arms 40 and 42 of spring 18. In other words, spindle 22, and attached detent 23, is retained in place, with rod 24 in the horizontal position, until an outside force of approximately five pounds or more is brought into contact with rod 24. If for example, a ligature is secured around rod 24, once five pounds of force is applied to the rod 24 by the ligature, the rod will move downwardly as spindle 22 spreads arms 40 and 42 of spring 18, and any ligature on rod 24 will fall or be pulled off the end of rod 24. In this manner, holder 10 incorporates many safety features which allow the holder 10 to be used in institutional settings where individuals may be a threat to themselves.
