Description
- THE PRESENT INVENTION relates to a hole puncher, and more particularly relates to an adjustable hole-puncher according to the preamble of
claim 1. - It has been proposed previously to provide an adjustable hole-puncher in which the position of at least some of the plungers provided to punch holes are adjustable, to enable hole combinations having different spacings to be punched using the hole-puncher.
- With a hole-puncher of this type it is difficult to place the plungers in the correct positions. EP0540827A1 discloses an adjustable hole-puncher according to the preamble of
claim 1 provided with an elongate cylinder which is pivotally mounted at each of its ends adjacent its plungers, and which is provided with a plurality of scales on its surface. A user of the hole-puncher may rotate the elongate cylinder to reveal a scale against which the plungers may be aligned to configure the spacing between the plungers. - The present invention seeks to provide an improved hole-puncher of this type.
- According to this invention there is provided an adjustable hole-puncher, the hole-puncher comprising a base, the base carrying a plurality of plunger assemblies, each incorporating a plunger and a co-operating die defining an aperture to receive the plunger, at least one of the plunger assemblies being adjustably mounted in position so that the spacing between that plunger assembly and an adjacent plunger assembly may be adjusted, therebeing an actuating handle mounted to the base, and actuable to drive the plunger of each plunger assembly into the corresponding aperture provided in the die thereof, there being an element rotatably mounted adjacent a slot formed in the base of the punch adjacent the plunger assemblies, the element being an elongate element of polygonal form presenting a plurality of flat faces, said faces carrying markings or indicia thereon, the element being rotatable between positions in which each said face is exposed within the slot adjacent the said plunger assemblies.
- Preferably there are four plunger assemblies.
- Conveniently each of the four plunger assemblies is adjustably mounted in position.
- In one embodiment the elongate element is of triangular section.
- In an alternative embodiment the elongate element is of square section.
- In a further embodiment the elongate element is of pentagonal section.
- Conveniently one of said faces is provided with indicia constituting a ruler, and others of said faces are provided with indicia indicating the appropriate positions of the plunger assemblies for different conventional types of paper.
- In order that the invention may be more readily understood, and so that further features thereof may be appreciated, the invention will now be described, by way of example, with reference to the accompanying drawings in which:
- FIGURE 1 is a front perspective view of a hole-puncher in accordance with the invention,
- FIGURE 2 is a rear perspective view of the hole-puncher of Figure 1,
- FIGURE 3 is an underneath view of the hole-puncher, and
- FIGURE 4 is a view of a component forming part of the hole-puncher of Figure 1, and
- Referring initially to Figures 1 and 2, a hole-
puncher 1 is provided which is of the adjustable type. The hole-puncher 1 comprises abase 2 to which is pivotally connected an actuating handle 3. A plurality ofplunger assemblies plunger 9 which can move downwardly in response to a downward movement of the actuating handle 3, and a paper-cutting die 10, located beneath the base of the plunger, which defines an aperture of the same diameter as the plunger. Each assembly has aclamping screw 11. - The
base 2 is provided with a retractable paper-guide 12 of conventional design. - The four plunger assemblies 4, 5, 6, 7 may be selectively positioned by releasing the
clamping screw 11 on each assembly which operates a clamping mechanism to retain the assembly in place, and then sliding the assemblies along the slot 7. When the assemblies have been positioned, a piece of paper may be located so that the edge of the paper is received between thedie 10 defining the aperture and theplunger 9 of each of theplunger units base 2. - In order to assist in the correct location of the
plunger units base 2 of thepunch 1 is provided with aruler arrangement 13 which is provided in thebase 2 immediately in front of theplunger units ruler arrangement 13 comprises anelongate element 14 of generally triangular cross-section provided at one end with amounting trunnion 15, and provided at the other end with amounting axle 16, which is co-aligned with thetrunnion 15, the mountingaxle 16 terminating with an actuatingwheel 17. The actuatingwheel 17 may have a knurledouter periphery 18. - The
element 14 is of equilateral triangular form, but in an alternative embodiment may have another polygonal form such as, for example, a pentagonal form. - The
element 9 is received within anelongate slot 19 formed in thebase 2 of thepunch 1, with thecontrol wheel 17 projecting through itsown slot 20 which is at one end of theelongate slot 19. The mounting mechanism includes a friction fitting which permits a positive "stop" when any one of the three flat faces of theelement 9 is substantially co-aligned with the upper surface of thebase 2 surrounding theslot 19. - Each of the three faces is provided with different markings thereon. The markings may comprise indications as to where the adjacent plunger assemblies 4, 5, 6, 7 should be located to punch different types of paper so that the paper, when punched, may be stored in conventional files. One face may include a ruler to facilitate the positioning of the plunger units at nonconventional, but precisely predetermined spacings.
- It is to be appreciated, therefore, that in using the hole-puncher of the invention as described above, initially one would determine the nature of the paper to be punched, or the specific spacing to be provided between plunger assemblies, and secondly one would rotate the
elongate element 14, using the actuatingwheel 17 until an appropriate face of theelongate element 9 is present within theslot 19, and is substantially parallel with the upper surface of thebase 2 surrounding theslot 19. The plunger assemblies 4, 5, 6, 7 would then be moved either to be aligned with specific markings provided on the exposed face of theelement 14, or to have specific spacings therebetween as determined by a ruler present on the exposed face of theelement 14. The hole-puncher will then be used in the usual way to punch paper. - In the present Specilication "comprises" means "includes or consists of" and "comprising" means "including or consisting of'.
- The features disclosed in the foregoing description, or the following Claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof, as long as the feature or combination of features falls within the scope of the claims (i.e. it must at least have all the features of claim 1).
