CN1077832C - Combination Hole Punch and Stapler - Google Patents

Abstract

The invention relates to a dual-function combined device consisting of a punch and a stapler, and two separate devices which can be detached from each other. The combination of these two devices economically provides a long lever arm that can be punched with a small amount of pressure and a stable stapler. The combination is obviously a space saving arrangement comprising a staple remover (25) and a standard 10mm staple magazine (26). Another aspect of this combination is that the stapler combination has a guide (23a, b, c) that provides alignment of the sheets for accurate stapling at a position parallel to the edge or along a 45 degree angle if desired.

Description

Combination Hole Punch and Stapler

The present invention relates to a hole punch and a stapler, especially a combination hole punch and stapler.

Hole punches and staplers are essential office equipment widely used for document and paper binding. Technically, these two devices work by pressing the handle, which pivots to make the various mechanisms work, and when pressed, returns by the jacking spring. Judging by the patents filed in different countries (USA, UK, Netherlands and Switzerland), the working principle of these devices has not changed much from 1922 to today. As can be seen, these developments and advances lie in the application of new materials, such as synthetic polymers, with which precision parts can be machined economically at reduced manufacturing costs.

At present, as far as the known technology is concerned, both the hole punch and the stapler are used as two separate devices with different functions, and therefore, it is obvious that a combined device has not been thought of nor patented.

Broadly speaking, it is an object of the present invention to combine a hole punch and a stapler into one device which performs both functions and which can be disassembled when required for separate use.

In order to achieve the above object, the present invention provides a combined hole puncher and stapler, comprising:

a main base having a first punch support and a second punch support spaced apart from each other, on said main base between said first punch support and said second punch support There is a clamping piece at one end and an elastic piece at the other end;

A punching mechanism for punching holes in paper is arranged in the first and second supports;

a punching handle, operatively connected to the first and second punching mechanisms, and having a central opening;

A stapler, which includes a stapler base that can be releasably fixed on the main base, one end of the stapler base has a clip that can be engaged with or separated from one end of the main base The other end has a clip that can be engaged with or separated from the elastic part at the other end of the main base, and the stapler also has a pivotable stapler handle that extends upward from the stapler It protrudes into the middle opening of the punching handle, and the shape of the middle opening of the punching handle can ensure that the user can operate the stapler handle.

Compared with existing punchers and staplers, the combined puncher and stapler of the present invention are much smaller in volume, saving space and production costs; save effort. In addition, the two can be disassembled for separate use if desired.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the picture:

Figures 12a, 12b and 12c respectively show three working states of the guide.

The space between the holes of the hole punch is used to combine the staplers, thereby having two functions in one device, and/or being detachable from each other for separate use as required.

On the main base 1 there are two supports 2a, 2b for the punch (see Figures 1, 2 and 3). Formed in the two supports are a punched pivot 18 , two segments 19 of the punched pivot and two helical springs 20 , as shown in FIG. 4 . The hole punch also includes a punch handle 21 and two hole punch pivots 22 . As shown in FIGS. 5 and 6 , both ends of the punching handle 21 are pivotally connected to the two supports 2 a , 2 b via a punch pivot 22 . In addition, there is a main base bottom cover 24 under the main base 1 (see FIG. 6 ).

As shown in Figures 5 and 8, the stapler base 3 is sunk in the recess at the centerline between the holes of the puncher, wherein, the clip 3a at one end of the stapler base 3 (please also refer to Figures 11a, 11b and 11c) It is releasably engaged with the elastic piece 4 at one end of the main base 1 , and the fastening piece at the other end of the stapler base 3 is engaged with the fixed fastening piece 5 at the other end of the main base 1 . This secures the stapler tightly to the main base. Guide and place the base of the stapler in the recess.

The stapler includes a spring 6, a staple bending pad 7, a staple box 8, a box head 9, a stapler handle 10, a staple push plate 11 and a stapler pivot 12. The spring 6 pushes away the staple case when the stapler handle is released, the cartridge head 9 is removed at a time and pushes out a staple, the stapler handle 10 pushes up the spring, and its opposite end forms a staple push plate 11. The stapler handle 10 rotates around the pivot 12 of the stapler. In addition, a guide 23 combined with the stapler is included.

As shown in FIGS. 5 and 7, there is an opening in the middle of the punching handle 21, from which the stapler handle 10 protrudes. The shape of the opening is convenient for the user to operate the stapler through the stapler handle 10 .

As shown in Figures 1-3, Figures 5, 6, and 10, a staple remover 25 that can be embedded with a staple remover 25 (a tool that removes staples from the bound paper) is formed on the main base on the side opposite to the punch support. standard device) bracket 13 and a fixed bracket 16 that can be embedded with a standard 10mm staple box. In addition, a locking piece 14 is formed on the punch handle, and a locking piece support 15 corresponding to the locking piece is formed on the bracket 13 . When the punch is not in use, the punch handle 21 is depressed to engage the lock 14 with the lock support 15, thereby allowing the device to take up less space. On the fixing bracket 16 of the staple box, there is also a locking member 17 for fixing the box.

After investigation, it was found that the functions of these devices and the combination devices after combination were improved.

Hole punch:

Because this device works on the principle of leverage, the force generated by the hand depends on the ratio of the lever arms. The longer the pressure arm compared to the punch arm, the less force is required or more sheets can be punched with the same force. But the increase in the pressure arm needs to be balanced by enlarging the base, which supports the punch to keep it axially and laterally stable. With regard to a single hole punch, however, it is unavoidable to produce an oversized and costly device in view of this situation. In order to avoid this shortcoming, the present invention utilizes the space between the two holes of the punch base to install the stapler, ensuring that the length of the pressure arm is exactly the length of the stapler, and the stapler can work freely after installation, thereby optimizing the The condition of the hole punch as described above. Thus, the present invention is advanced by increasing the shorter pressure arm from 1x5 to 1x9 with a commonly used standard two-hole punch punching ratio. Therefore, the same number of sheets can be punched with almost half the force, or twice as many sheets can be punched with the same force.

stapler:

1-A significant problem of general mechanical staplers is that the binding position on the paper to be bound is not very exact. In fact, even with great care, it is very difficult to accomplish the standard-specific binding of the documents being processed, and it is entirely dependent on the level of the operator.

Another invention of the combined device is a guide 23a, 23b, 23c (Fig. 12a, b, c), fitted together with the stapler, to ensure the alignment of the sheets so that the Accurate binding at the 45-degree angle position solves the uncertainty when determining the binding position and standardizes accurate binding.

2 - The additional width of the support alignment guide increases the stability of the stapler base, which is where the present invention is superior to typical narrow base staplers.

3-The handle of the pressure arm is designed to increase the pressure area through the circular arch surface, so that the operator can press with the thumb or the edge of the palm, which is convenient for generating the force required for binding the paper to be bound.

Advantages of combined units:

1-The advantages of the above mentioned hole punch and stapler when used separately also exist when these two devices are combined into one.

2- In addition to the hole punch and stapler combo, the combo has a staple remover 25 built in and a standard 10mm staple cartridge 26 on the main base. Therefore, through this combination, a compact and convenient office equipment is formed.

It is understood that in the stationery and office supplies market, various devices are bought individually, or as a set in some kind of packaging. In contrast, the combined device of the present invention occupies only one-third the volume of such commercially available packages, because the present invention is designed to fit four devices in one main base. Moreover, it not only saves space in the office or home, but also can be easily carried when you need to deal with files and papers when you are on a business trip.
