Description
SPECIFICATION
Lockable roll holder
This invention relates to roll holders, particularly for toilet rolls.
The present invention provides a roll holder comprising a spindle on which a roll is capable of being positioned, a pin projecting from each end of the spindle to be received in apertures in a support for the spindle, and restriction means for limiting removal of the contents of the roll, said restriction means comprising a locking device in the spindle operated by a removable key for preventing removal of the pins from the apertures of the support and/or means for limiting the amount by which the spindle may rotate relative to the support.
The invention can be used for holding any suitable roll, particularly a toilet roll but also for paper towel rolls or the like. The invention enables the following possibilities to occur with a toilet roll:
(a) The amount of toilet paper removed at one pull is limited, or
(b) The total removal of the toilet roll issubstan- tially prevented, or
(c) Both of (a) and (b) can be provided.
Conveniently, one of the pins is slidable axially towards the other pin when the locking device is unlocked. In that embodiment, the amount by which the other pin projects from the end of the spindle can be adjusted once the spindle has been removed from the support, eg by means of a screw thread.
This enables the toilet roll holder provided by the invention to be adjusted in length to fit different sized supports (such as box-like receptacles) for it.
The toilet roll holder may be used to fit within any suitable receptacle, particularly a receptacle of the type provided with a pair of laterally opposed apertures in which an axially expandable toilet roll holder is normally provided.
Only one pin preferably is axially movable. The movable pin may be biassed axially outwards from the centre of the spindle by means of a spring. The pin may be integral with a body member slidable within the spindle, said body member having a ratchet formed therein and adapted to receive the removable key which includes a gearwheel at its end. The spindle conveniently comprises an abutment across its interior, and positioned between the ends thereof, against which a spring abuts. The movable pin conveniently abuts against the spring and may slide in an axial passageway. On the other side of the abutment (which may be centrally positioned or positioned to one side of the centre) the further pin can abut. Conveniently, the pin on this side of the said abutment may not be movable axially but may be rotatable with respect to the abutment.The abutment in the spindle may contain one or more apertures in which legs of the body member are slidable.
The end of the pin projecting axially from the spindle on this side of the abutment may be received in a cup. The cross-section of the cup and the pin may be other than round, so that the pin may not rotate in the cup. A ratchet device may be provided between either the cup and the pin or the pin and the central abutment to limit the rotation of the pin. In this embodiment, the number of revolutions which the spindle may perform is limited, thereby limiting the amount of paper which can be removed at any one time.
For example, the ratchet may be such that the spindle may revolve twice before being brought to a stop. It is necessary then to release the paper momentarily before a further two revolutions can be effected. With such a ratchet device the amount of paper removed at any one time can be limited, effecting a saving.
Where there are separate pins projecting outwardly axially from a central abutment, and only one of the pins is biassed by a spring against the central abutment, it is necessary to lock only that pin.
Should both pins be biassed by springs against the said abutment, locks can be provided on both sides of the abutment.
The roll holder provided by the invention may be of circular cross-section but conveniently is of a non-circular cross-section which more effectively limits rotation of the roll with respect to the roll holder. For example, the roll holder may be of square, rectangular or triangular cross-section.
Alternatively, flanges can project diametrically outwardly from the spindle so that a roll slid thereon is not of circular cross-section.
Conveniently one of the pins is prevented from rotating relative to the support but is permitted to rotate in a limited manner relative to the spindle.
Alternatively, one of the pins is prevented from rotating relative to the spindle but is permitted to rotate in a limited manner relative to the support. In these embodiments a stop means can be provided to limit rotation, said stop means only becoming operative when an attempt is made rapidly to rotate the spindle.
One end of the spindle can be provided with a neck, in the circumference of which a spigot is slidable under gravity. A collar which is rotatable around the neck can have the pin projecting fixedly therefrom, the collar having an abutment on its internal curved surface against which the spigot can abut, the pin being adapted to be fixedly received in the support. In this case, the spigot can fall under gravity, if the spindle is rotated slowly, until the spigot does not abut against the abutment, so that the spindle then rotates freely. On the other hand, if the spindle is rotated rapidly, the spigot cannot fall under gravity to the 'free' position, but is held by friction in the dependent position, thereby causing it to abut against the abutment and limit the rotation of the spindle.
The length by which the pins project from the spindle may be adjustable so that the roll holder provided by the invention can fit a number of different spaced-apart apertures. The apertures can have cups to receive the ends of the spindles, one of the cups preferably being other than of round cross-section. Alternatively, other means may be provided for locking one of the pins.
The locking device may include a butterfly flange movable from a position substantially at right angles to the longitudinal axis of the spindle (in the unlocked position) to axially of the spindle in the locked position. When in the locked position, the flange prevents movement of the pin towards the centre of the spindle.
Alternatively, the locking device may comprise a rack and pinion system, the rack conveniently being formed in the side of the movable pin, with the pinion being operable by a key.
In an alternative embodiment, the locking device may comprise a tumbler lock. In this embodiment, the pin need not be spring loaded.
In all the embodiments described, the keys are removable once the locking device has been locked.
A single key may be provided for use with a plurality of toilet roll holders. Alternatively, a set of keys can be provided for different toilet roll holders, eg in a complete building.
The toilet roll holder provided by the invention may be made of any suitable material, the actual material depending on the type of security required and the cost to be spent by the purchaser thereof.
The toilet roll holder may be of wood, steel, aluminium or a plastics material, or may involve two or more such materials.
A preferred embodiment of the invention is illustrated by reference to the accompanying drawings in which:
Figure 1 is a vertical cross section through a toilet roll holder according to the invention; and
Figure2 is a cross section along Ill-Ill of Figure 1; and
Figure 3 is a cross-section of another embodiment.
In these Figures, a toilet roll holder shown generally at 30 comprises a hollow spindle 32 having pins 34,36 projecting axially from the ends thereof. The spindle 32 is divided by a central abutment 38 into a left hand part 40 and a right hand part 42. The parts 40 and 42 are hollow.
Legs 44,44.1, etc of a body 46 project through apertures in the abutment 38. Pin 36 is fast with body 46 and is biassed outwardly (i.e. to the right) by spring 48 towards cup 50. Instead of the separate spring 48, the central leg may be of helical shape and abut against the central abutment 38.
End 52 ofthe left hand pin 34 fits in a cup 54 which is prevented from rotating by suitable means, e.g. by being stuck (such as with adhesive tape) to a support 55 or by being of non-circular cross section (for example triangular) and fitting in a corresponding shaped hole in the support 55. The pin 34 has a screw thread on its exterior surface which screws into collar 56 so that the distance by which the pin 34 projects from the collar 56 can be adjusted. The thread is a tight fit so that the pin 34 is effectively fast with the collar 56. The end of the pin 34 contains a slot to receive a screwdriver or the like in order that the portion of the pin with respect to the collar may easily be adjusted once the pin has been removed from the cup 54.The slot locks in an internal projection of the cup 54 to prevent the pin 34 rotating relative to the cup 54 which is rotatable around a neck 58 of the spindle. A stop 60 projects inwardly down from the top of the collar 56. Slidabie in a groove in the neck 58 is a spigot 62. When rotating the spindle slowly, the spigot falls under gravity until it misses the stop 60, when moved rapidly, the spigot continues to project from the neck 58 and hits against the stop 60, thereby limiting rotation in either direction.
Shaft 62 of the collar 56 has snap fit projections 64 on its free end to prevent removal of the shaft 56 from the neck 58. Similarly the free end of the body 46 has snap fit projections 66 to prevent removal from the abutment 38.
Body part 46 has an elongated aperture containing a plurality of ratchet teeth 64, into which a toothed wheel 66 can be inserted. A key is provided (not shown) for enabling the position of the teeth 68 in relation to the wheel 70 to be adjusted. When in the position shown, the right hand pin 36 projects outwardly from the end of the spool 32, preventing unauthorised removal. The key may also include a screwdriver projection to fit in the slot of the pin 34.
Flanges 80,80.1 etc. project radially outwardly from the spindle 32. The flanges are of a size and shape to deform a toilet roll core sufficiently for it to be difficult, or impossible, for the core to rotate relative to the spindle.
In Figure 3, the spindle 70 can be of square cross-section or of triangular cross-section (shown in broken lines). In both these embodiments (which are on a smaller side than Figures 1 and 2), the spindle 70 abuts against the inside of a toilet roll 72 and the friction between the spindle 70 and roll 72 limits the rotation of the roll 72. Thus, no flanges are necessary.
The invention has the advantages that it can fit conventional toilet roll supports and can be substituted for existing toilet roll holders in such supports to provide security. The toilet roll holder is inexpensive to manufacture and easy to fit. Instead of being used for toilet rolls, it can be used for paper towels or the like.
The locking device may alternatively be tumbler key operated. The pin may be operated from either side of the roll holder.
