COMBINED PAPER PUNCH AND STAPLER

Abstract: This invention relates to a combined unit with two functions, formed by a paper hole punch and a stapler, and/or to two separate devices by detachment from each other. The combination of these two devices secures economically a long lever arm to punch at low pressing force and a very stable stapler. The combined unit is obviously a space saving set comprising also a staple bar remover (25) and a standard package (26) of 10 mm staple bars. Our additional invention on this combined unit is a guiding device (23a, b, c) (Fig. 12a, b, c) incorporating with the stapler securing alignment of paper sheets to staple accurately at points either parallel to edges or at 45 degree angle alternately as required.

Description: DESCRIPTION COMBINED PAPER PUNCH AND STAPLER This invention relates to turn the space between holes of a paper punch to advantage by combining it with a stapler so as to attain one unit with two functions and/or detach the two devices from each other to employ and make use separately and independently as required. The combined unit comprises the following parts: One main base(l), on this main base are two supports(2a, 2b) of the hole punching mechanism, the stapler base(3) bedded in its indent at the center axis between the punch holes, a catch(3a) to attach or detach the stapler base to or from the main base, the spruιg(4) to fix the stapler to the main base firmly, the fixation cntrh( r >) to guide and place the stapler base in the indent, the spring(6) to lift off the stapler magazine upon release of the pressing handle, the staple bar folding bed(7), the stapler magaziιtc(8), the magazine head(9) to clear and push one staple bar al a time, the stapler handle (10), the combined handle lifting spring witli the opposite end formed as staple bar pushing plate(ll), the pivoL(12) of the stapler median. , the indent with bracing(13) to nest the staple remover(2> )(the standard device to remove staple bars from bi ruled paper sheets), the punch handle fixation lock(14), the support(15) of the lock, the indent with fixation bracings(16) on the main base to nest standard package of 10 mm staple bars, the lock(17) of t lie package fixation, the t o punching pivots(lδ), the two punching pivot segments(1.9), the two helical springs(20), the punching hand1e(21), the two ρivots(22) of the punching mechanism, the guiding device(23) incorporating with the stapler, the main base bottom cover (24), the staple remover (2 r >), the standard package(2G) of 10 mm staple bars. The paper punch and stapler as two indispensable office equi ment are employed in filing and paper binding extensively. Technically, these two devices are activated by pressing handles, which are pivoted to the functioning mechanisms of each, and are rebound by lift off springs after pressing. It is reviewed through the patents registered in different countries (U.S.A., England, The Netherlands and Switzerland) that since 1922 to this date there has not. been significant change in the operating principles of these devices. As reviewed, the development and progress were rather on utilization of new materials such as synthetic polymers with which it is economical to manufacture precision parts reducing production costs. To tliis date, in regards to known technology, the punch and t lie stapler have each found acceptance for use separately as two devices with different unalike functions, thus obviously a combined unit has not been thought of and not been patented. In essence, the objoc- tive of this invention by combining the punch and the stapler, is to form one unit with two functions and to detach the two devices whenever it is needed to employ each separately and independently. Furthermore, through investigation it is found that functional improvements on these devices, as well as the combined unit resulted from this combination. The punch: As Llvis device functions by lever principle, the force exerted by hand is dependent on the ratio of the lever arms. The longer the pressing arm compared to the length of punching arm, the less force with ease is required or with the same force more sheets of paper could be punched. However, increase of the pressing arm needs to be counter balanced by enlarging the base, which is supporting the punching mechanism to secure stability axially and laterally. But, should this fact has to be considered for punch alone, manufacture of a large, oversize and costlier device is inevitable. Avoiding this drawback, our invention making use of the empty space between the two holes of the punch base by installing a stapler, secures a pressing arm length just to the length of the stapler, which is to operate freely when attached, thus optimizing the aforesaid punching ease of the punch. Accordingly, an advantage is secured over the rather short pressing arm of the commonly used standard two-hole punch's punching ratio by increasing to 1X9 from 1X5. Thus, by exerting almost one half of the force, same number of sheets could bo punched or with the same force the number of sheets to be punched could be doubled. The stapler: 1- One issue of significance with the regular mechanical st pler is approximation of stapling points on the paper sheets to be b hided. In fact, despite care, stapling proper to the standards of document handled is hardly achieved and is wholly dependent on the ski 11 of the operator. Our additional invention on the combined unit is a guiding device (23a, b,c) (Fig.l2a,b,c) which is incorporated with the stapler to secure alignment of papers to staple with accuracy at points either parallel to edges or at 45 degree angle with the top 1 ofI corner of the sheets to resolve approximation uncertainty in determining stapling points and to standardize accurate stapling with precision. 2- The extra width bearing the alignment guides adds stability to the stapler base, an advantage over regular narrow base stnplorr.. 3- The handle of the pressing arm is designed to increase pressing area with a rounded crown as to enable the operator to press by either thumb or palm edge, whichever is convenient to exert at ease the force needed to staple the sheets to be hi ruled. The advantages of the combined unit: 1- The aforesaid advantages described in the use of punch and stapler separately is in effect the same when these two devices are combined to form one unit. 2- The combined unit, aside from joining the punch and the stapler nests one staple remover(25), and one standard package of 10 mm staple bars(26) in the main base. Thus, a compact handy office set is formed by this combination. As known, in the stationary and office supplies market each device is sold separately or as a set in package of some kind. l!y comparison, our combined unit occupies less than a third the volume of the packages marketed, because ours is designed to arrange properly four units all in one main base unit. Nevertheless, it: is space saving not only in the office or home, but also could be conveniently carried along on business trips where it is needed to do paper work and filing.
