PAPER ROLL HOLDER BACKGROUND or THE INVENTION This invention pertains to a locking roll holder such as'might be used to hold rolls of paper towels, toilet paper or any other expensible paper, cloth or other light material.

In public places where such rolls of material are displayed, it is quite common for the rolls to be stolen, thereby denying them to the use of persons properly needing them. In addition to the expense of replacing the material sold and the inconvenience to the potential user, of such devices in public places, often the removal of the roll is the preclude to pranks, demonstrations or to the use of the rolls and the holders for them as weapons.

In an era when demonstrations in public places are common and when it is common to wreck or destroy public facilities in protest to some action taken by a public body, it is more important than ever to secure the simple items such as toilet paper and paper towels and the like to prevent them from being used against the institution and the people within it by those on the outside or inside.

Those devices taught in the prior art include U.S. Pat. No. 3,038,677 issued to AC. Schermerhom; U.S. Pat. No. 2,324,796 issued to Neptune; and U.S. Pat. No. 1,345,190 issued to Hutchison.

The Schermerhorn patent teaches a dual roll holder in which there is a latch locking device. The latch may be lifted by a straight key or screwdriver type instrument which rotates the latch backwardly and releases the dowel pin latch.

Naturally, any small instrument which fits into the slot including a tie pin, pencil, large paper clip or any similar instrument would be sufficient to press against the spring and release the latch..

The Neptune and Hutchison patents teach tension devices which present the rapid unwinding of rolls. In Neptune, a screw member can be tightened or loosened to maintain or release the pressure on the roll, while in Hutchison a threaded member can be tightened down against a resilient member to increase or reduce the pressure against the roll. v

Other holders are illustrated in U.S. Pat. No. 1,308,912 issued to MacCormic and U.S. Pat. No. 1,299,413 issued to Anable which show locking devices internal into the roll mechanism. In such types of mechanisms it is necessary to completely use the roll of material in order to remove the tube on which the roll is wound or to place another roll on the holder. In many cases, it is necessary to change the roll prior to its complete use. This may occur if the roll is dampened or damaged in some way such that it is no longer servicable for its purpose. In the Anable and MacCormac devices, it is necessary that you cut the roll away or in some fashion remove it before the lockingdevices can be unlocked and a new roll placed on it. This can be an annoying burden in public institutions or private which requires time and effort for someone to remove tha roll of material.

Yet other devices are shown in U.S. Pat. No. 2,215,053 issued to Reese and U.S. Pat. No. 1,158,577 issued to Spall.

The Reese and Spall devices employ padlocks to hold the roll of material onto its frame. In such devices, the

locks are generally small and fragile and may be picked or broken easily by a screwdriver or pliers or a good, swift kick.

It can be easily seen fromthe review of the prior art that it falls into three basic categories:

1. There are known tensioning devices for roll holders.

2. There are known locking devices which use the material itself as a shield for the lock but that do not allow for change of the roll until it is substantially finished; and I v 3. There are external locking mechanisms which use padlocks which are relatively vulnerable to breakage or i being picked.

SUMMARY OF THE INVENTION None of the solutions in the prior art were entirely satisfactory. The tensioning devices were readily subject to outside tampering and easy removal permitting removal of the roll and the holders for the roll. The devices which lock within the roll of the material being held did not provide for easy access to change the roll if it were damaged or improper material or for any other reason which requiredits changing. The padlock devices were subject to ready destruction at the hands of people who wanted to remove the roll of paper and wanted to use its support as a weapon.

The present invention solved these other problems in a very simple and unique manner. That solution in one embodiment requires a total of only four major parts: the anchoring device, a tubular device which fits in the channels formed in the anchoring device, and a locking mechanism which grips firmly the tubular device to the anchoring device, and a key which can be used to unlock the mechanism.

Because the key is applied externally to the tube device, it is not required to utilize the entire roll or to destroy the roll before it is removed and another placed on the holder.

Because the locking device anchors the tubular device to the anchoring member and uses an internal surface as a part of the locking structure, it is not subject to easy destruction such as padlocks.

It is an object of the present invention to provide a self locking roll holder which is openable only by an uncommonly carried and unpickable but simple key-lock mechanism.

' It is an object of the present invention to provide a relatively non-destructable locking mechanism for a roll holder. I

It is an object of the present invention to provide a locking device for a roll holder which does not require the destruction or useof the entire roll prior to release of the lock.

It is an object of the present invention to provide a unique, simple four-piece self-locking roll holder device.

It is an object of the present invention to provide a very strong light-weight, simple to manufacture roll holder which isself-locking.

vention may be more fully understood by reference to the drawing and description following the drawing.

In the Figures, like numerals are used to designate like parts with a hundreds number prefix indicating a different embodiment of that part.

FIG. 1 shows a perspective view of one embodiment of the present invention. An anchoring member indicated generally by the numeral 10 has a first outwardly extending arm 16 and a second outwardly extending arm 18. Channel 20 is provided in arm 16 and channel 22 is provided in arm 18.

Arms

16 and 18 are joined by support plate 11. Slots 12 and 14 are provided in plate 11 so that screws or bolts or other mechanisms may be used for fastening the anchoring device to a wall or other structure.

A tubular member generally formed as cylinder 24 is shown adapted to mate with

channels

20 and 22.

A cap member 40 is adapted to be engagable with tubular member 24 in order to lock tubular member 24 between arms 16.and 18.

End 30 of tubular member 24 has a channel'36 axially journaled thereinto. An axial member 46 is attached to cap member 40. Axially extending member 46 is lockably engagable with channel 36.

In the preferred embodiment of this invention member 46 comprises a shank portion 57 and a head portion 48, preferably shank portion 57 has threads 59 cut therein. In this embodiment channel 36 has threads 39 cut therein. Threads 39 and 49 being mutually engagable.

In the preferred embodiment of the invention, annular cap member 40 has a central channel 44 formed therethrough which has an enlarged annular section 42 therein having an axial depth less than the axial thickness of cap member 40. The diameter of central channel 44 is predetermined to readily receive shank portion 57 of member 46 there-through and the diameter of the enlarged annular section 62 is predetermined to receive head portion 48 therein.

In one of the preferred embodiments of the present invention a clearance between the inner circumference of channel 42 and the outer circumference of head 48 is just sufficient for head 48 to be readily rotatable therein. Preferably, the axial depth of head 48 is substantially equivalent to the axial depth of channel 42. The head portion 48 of member 46, has, in one embodiment of the present invention, a key-way 51 of predetermined dimensions formed axially therein. The dimensions of this key-way are not critical and may be chosen at convenience, however, a hexagonal key-way ment the outer circumference of head 448-is formed in a predetermined gripable shape, suitably having at least one planar surface parallel to the axis of member 446. While the actual shape chosen is not critical, it is found practical to provide head 448 with a cross-section in the plane perpendicular to the axis of a square, triangle, or, as shown in 448, a hexagon.

Although

members

40 and 46 are shown as separate members those skilled in the art will recognize that they can be formed as one member. In this circumstance head 48 becomes an integral part of cap member 40. However, it has been found that while the device is operable in this fashion, the security of the device is greater when

members

40 and 46 are separate, and production of the device is more economical when

members

40 and 46 are separate. Since the head portion 48 is subject to substantially tangential stress, it is preferred to utilize a hard metal such as steel or iron, while the cap member may be formed of an inexpensive and readily machined, comparatively soft metal such as aluminum or alloys thereof. v

Tubular member 24 has an annular channel 26 formed in end 28 thereof so that the portion of extending arm 16 surrounding channel 20 or arm 18 surrounding channel 22 are adapted to engage in annular channel 26. Annular channel 26 having an axial width slightly greater than the thickness of

arm

16 or 18.

The other end 30 of member 24 has an axially extended portion formed thereon which is adapted to engage

channels

20 or 22 of extending

arms

16 and 18, suitably, in a manner which will prevent the rotation of member 24 about its axis.

In the preferred embodiment of the present invention the width and dimensions of extended portion 34 correspond substantially to the width of the channel with which they are engagable. Thus, in FIG. 3 the extended portion is defined between 2 parallel cords and the circumference joining said cords. It will be recognized by those skilled in the art that where, for example, channel 22 is V-shaped, the cords partially defining extended portion 34 will correspondingly mutually subtend an acute angle.

In utilizing the device of the present invention, the anchoring member 10 is fixedly secured to some structure in the building in which it is to be used, such as a wall, door, or partition. Where the device is to be anchored in a partition, it has been found most useful to anchor two devices of the present invention to each other through the partition. Such a mode of anchoring makes removal of the device from the partition virtuchannel 22. It should be noted that it is preferred to provide channels and 22 with the same dimensions so that channel 26 is engagable in channel 22 and extended portion 34 is engag able in channel 20.

It should be noted that the axial depth of extended portion 34 may be the'same as or less than the width of the outwardly extending arm with which it is engaged. It should be noted that if the axial depth of extended portion 34 is even slightly greater than the width of the outwardly extending arm, the locking mechanism of the device of the present invention would not be operative.

It may be anticipated that in the course of production of the devices of the present invention, variations may occur in the thickness of the material utilized for anchor l0 and the extending

arms

16 and 18 thereof. If, for example, a replacement roll were to be provided for an anchor of a previous production run wherein the width of the outwardly extending anchor arm is less than the axial depth of extension 34, the device would not lock using'c'ap 40. This undesirable effect can be readily avoided, as shown in FIG. 9 utilizing cap 640 which is provided with a counter-channel 646 having a diameter slightly greater than the diameter of tubular member 24 and a depth sufficient to receive therewithin any portion of member 34 which extends beyond the outer surface of outwardly extending arm 18.

Cap member 40 is placed over the axially extending portion 34 with channel 44 located co-axially with channel 36. Axially extended member 46 is passed through channel 44 and engaged Y with channel 36. Where shank portion 57 has threads 59 thereupon engagable with threads 39 in channel 36, member 46 is screwed into channel 36 engaging cap member 40 thereto. In the embodiment of FIG. 5, key 100 is placed in key-way 151 in head 148 and the member 46 tightly engaged with channel 36 so that arm 16 is drawn by end portion 28 toward arm 18, and arm 18 is drawn towards arm 16 by cap member 40. It is especially preferred that the axial depth of channel 42 be equal to or slightly greater than the axial depth of head portion 48 of axially extended member 46 so that when member 46 is fully engaged with cylinder 24 all or substantially all of head portion 48 is received within channel 42.

Where head 448 is provided with a predetermined circumferential gripable surface, a corresponding female key is utilized to accomplish the same result.

Because the tubular member will not rotate, no person would be able to release the lock thus attained by attempting to rotate the cylinder member 24 to cause the screw member 46 to rotate relative to the cylinder member 24. Therefore, without a key such as the hex key, or in the appropriate case a socket member, no one can remove the cylinder from the arms and therefore remove the roll or the tube to use either in a destructive way or to remove them tosteal them.

Because the head portion 48 is recessed within the cap member 40 no other external device can grip it and rotate the member to release the tubular member 24 from the anchoring device 10.

Notice that annular slot 26 must be of sufficient axial dimension to allow tubular member 24 to move axially with respect to the holder member or anchoring member 10.

it is clear that the present invention accomplishes all of its stated objects and that a novel and simple locking device can be made for a roll holder out of four major parts, which is virtually impossible to remove without a key and yet which does not require the use of the entire roll in order to get at the releasing mechanism.

The present invention is simple to manufacture, easy to use, and accomplishes all of its stated objectives.
