Definitions
- THE PRESENT INVENTION relates to a hole punch for punching holes through a sheet article or stack of sheet articles, such as paper and other stationery according to the preamble of claim 1.
- a hole punch according to the preamble is disclosed by EPO121580A.
- a hole punch configured to punch circular holes commonly consists of one or more cylindrical cutting elements which may be forced through the articles to be punched using a sprung plunger device.
- the articles must be correctly loaded into the hole punch, in order to achieve a desirable result. For example, paper must be inserted into a hole punch to a predetermined position, in order that the holes are punched at a suitable distance from the edge of the sheet. If the holes are punched too close to the edge of the sheet, then the sheet may easily be ripped.
- Articles such as paper which have been punched in such a device are commonly stored in binders or folders having rings of corresponding orientation and dimension to the cutting elements of the hole punch.
- EP0121580 discloses a hole punch wherein the lower surface of the slot is inclined upwardly relative to a worksurface upon which hole punch is placed, in the direction in which sheet-like articles are introduced into the slot.
- the present invention seeks to provide an improved hole punch.
- a hole punch for punching holes through a sheet article or a stack of sheet articles, the hole punch comprising: a base, an operating handle, and at least one cutting element, the or each cutting element being operable under the action of the handle to move towards the base; the base having a substantially planar supporting surface for engagement with a worksurface, an opposed engaging surface to engage the face of a sheet article to be punched, and locating means configured to engage an edge of the or each sheet article in a predetermined position relative to the or each cutting element, wherein the engaging surface is inclined with respect to the supporting surface such that the engaging surface has a minimum spacing from the support surface substantially at the position of the locating means.
- the engaging surface is substantially planar.
- the angle of inclination of the engaging surface with respect to the supporting surface is between 1° and 15°.
- the angle of inclination of the engaging surface with respect to the supporting surface is between 4° and 12°.
- the angle of inclination of the engaging surface with respect to the supporting surface is 8°.
- the hole punch 1 comprises a base unit 2 having a planar, or substantially planar undersurface 3 (illustrated in Figure 4) to facilitate secure positioning of the base 2 of the hole punch 1, upon a static worksurface 4, such as, for example, the upper surface of a table or workbench.
- a pair of spaced apart, opposed and substantially identical planar flanges 5 Upstanding from the base 2, are a pair of spaced apart, opposed and substantially identical planar flanges 5 to which is pivotally mounted an operating handle 6.
- the pivotally mounted operating handle 6 is operatively connected to a pair of moveable cutting elements 7 in the form of substantially cylindrical metal pistons which are vertically moveable with respect to the base 2 in a manner known per se.
- each upstanding flange 5 is provided with an aperture 8 therethrough.
- the two apertures 8 are aligned with one another, and each aperture 8 receives therein, as a rotational fit, a spigot 9 extending inwardly from a respective planar sidewall 10 of the handle 6.
- Each sidewall 10 of the handle 6 is disposed against the outer surface of a respective upstanding flange 5.
- each cutting element 7 the operating handle 6 is provided with a bearing surface 11 arranged to bear against the uppermost surface 12 of a respective cutting element 7. Therefore, as illustrated in Figures 4 and 5, actuation of the operating handle 6 from the initial position illustrated in Figure 4, to the operative position illustrated in Figure 5, causes the bearing surfaces 11, by virtue of their engagement with the upper surfaces 12 of respective cutting elements 7, to urge the cutting elements 7 downwardly towards the base 2 such that the lower, sharpened edges 13 of the cutting elements approach the base 2.
- Each cutting element 7 is biased towards its initial position illustrated in Figure 4, by virtue of a helical compression spring 14 disposed around the respective cutting elements 7, also in a manner known per se in the field of hole punches.
- each cylindrical surface 15 is sized and configured to receive therein the lowermost end of the respective cutting elements 7, as the cutting elements 7 approach their operative positions, as illustrated in Figure 5. It will therefore be clear from Figure 5 that when each cutting element 7 is located in its operative position, such that its sharpened edge 13 is received within a corresponding recess 15a, that the sharpened edge 13 has passed below the engaging surface 15, and hence through any sheets of paper or the like resting against the engaging surface 15 of the hole punch.
- the base 2 is provided with an upper engaging surface 15 which is opposed to the undersurface 3.
- the engaging surface 15 extends from a position indicated generally at 16, in front of the floating handle 6, to a position substantially below and behind the sharpened edges 13 of the cutting element 7. In this position, the engaging surface 15 terminates at an upstanding step 17 defining a locating means in the form of a locating surface 18 which is preferably orientated so as to be substantially perpendicular to the engaging surface 15.
- the locating surface 18 provides an abutment against which one or more sheets of paper or the like can be engaged when inserted into the hole punch against the engaging surface 15 and below the cutting elements 7.
- the locating surface 18 is configured to engage an edge of the or each sheet of paper or the like inserted into the hole punch, in a predetermined position relative to the or each cutting element 7, thereby defining the "fully home” position of the or each sheet of paper in the hole punch.
- the engaging surface 15 is inclined downwardly in the orientation illustrated, towards the supporting surface 3, such that the engaging surface 15 approaches the support surface 3 in the region of the locating surface 18.
- the engaging surface 15 is inclined with respect to the supporting surface 3, such that the engaging surface has a minimum spacing D from the support surface substantially at the position of the locating means 18.
- the engaging surface 15 is inclined with respect to the horizontal, which assists in positive location of paper sheets in the hole punch, and serves to help prevent inadvertent disengagement of the paper sheets from the hole punch.
- the downwardly inclined engaging surface uses the force of gravity to maintain sheets of paper inserted into the hole punch in their correct position against the locating means 18.
- the particular hole punch 1 illustrated is also provided with an optional optical waveguide 19, such as, for example, a conventional light pipe.
- the optical waveguide 19 is oriented substantially vertically such that its lowermost end 20 is located substantially immediately above the juncture between the engaging surface 15 and the locating surface 18, against which edges of sheets of paper to be punched become engaged when fully inserted into the hole punch.
- the uppermost end 21 of the optical waveguide is, in the orientation illustrated in Figure 4, located substantially vertically above the lowermost end 20.
- the uppermost end 21 of the optical waveguide 19 is received within the narrow end of a generally frusto-conical shaped funnel or sleeve 22 which is mounted with respect to the operating handle 6 at a position immediately below an aperture 23 through the uppermost surface of the operating handle 6.
- the light pipe of the above-described arrangement is preferably moulded from plastics material such as, for example, acrylonitrile butadiene styrene (ABS).
- ABS acrylonitrile butadiene styrene
- the sleeve 22, in the most preferred embodiment, is moulded from vacuum plated styrene material.
- the optical waveguide 19 serves to propagate light, for example, ambient light in the region of the locating surface 18, from the position of the locating surface 18 to the sleeve 22 in a position remote from the locating surface 18.
- the light pipe 19, in optical communication with the aperture 23 through the uppermost surface 6 of the operating handle 6, serves to provide a visual indication of the presence or absence of sheet articles, such as, for example, paper, in the area immediately below the lowermost end 20 of the waveguide 19, i.e. in the region of the locating surface 18.
- a person looking downwardly (indicated schematically at 24) to the aperture 23 will, by virtue of the propagating properties of the optical waveguide 19, be able to view the region below the lowermost end 20 of the waveguide 19, i.e. the region of the locating surface 18.
- the lens 25 is preferably configured for snap engagement with the sleeve 22, through the aperture 23 formed in the uppermost surface of the operating handle 6.
- the lens 25 is preferably circular or substantially ovoid in configuration, as illustrated in Figure 3, and is provided with a downwardly-depending skirt 26 therearound.
- the lowermost edge of the downwardly-depending skirt 26 is provided with an outwardly-projecting projection or lip 27.
- the innermost surface of the sleeve 22 is provided with a groove 28 therearound sized and configured to receive and engage, as a snap fit, the projection or lip 27 carried by the skirt 26.
- the lens can simply and easily be inserted into the sleeve 22 by positioning the lens 25 over the aperture 23 such that the skirt 26 passes through the aperture 23 and into the sleeve 22, whilst being urged inwardly, until the outwardly-directed projection 27 becomes aligned with the corresponding groove 28, at which time the skirt 26 springs back, by virtue of its inherent resilience, such that the projection 27 is received within the groove 28, thereby retaining the lens 25 in position.
- the lens 25 is preferably configured to disperse light propagated along the waveguide 19 towards the aperture 23 so that a person viewing the lens 25 from generally above the lens, can easily assess a change in optical conditions in the region below the waveguide (for example upon the insertion or removal of sheet articles), without requiring absolutely precise alignment of the person's line of sight with the axis of the waveguide 19. It is also proposed that the lens 25 could be a coloured lens.
- the lens 25 is preferably colourless, but the optical waveguide 19 is configured so as to impart colour (for example green) to light reflected from a sheet of paper located below the lowermost end 20 of the waveguide 19, as that light is propagated along the waveguide 19.
- colour for example green
- Such an arrangement provides a visual indication of (say) green light dispersing through the lens 25 upon insertion of paper into the hole punch in the "fully home" position.
