Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folder, a notebook and a binder, and more particularly to a loose-leaf binder having a device for perforating paper.

[0002]

2. Description of the Related Art Conventional loose-leaf binders, which are well known in the related art, are used as a means for holding documents.
Generally, a ring member or a straight pipe member is used. These two types of loose-leaf binders are also commonly used by students and intellectual professionals and others who need to hold, organize and / or protect paper and documents.

[0003] Ring binders, well known in the related art, are mounted on the central panel in such a way that the ring members must be opened and closed clearly in order to receive and hold the paper. Generally includes a mating ring member arranged and adapted along a rectangular spring plate housed in the frame. Conventional ring binders are disclosed in U.S. Pat. No. 4,522,526,457382.
2,4584222, 4690580 and 472262
8 and other references. A conventional pipe-type binder well known in the related art is a pipe member having two elongated fork-like branches, a base member disposed on a central panel having two tubes for receiving the fork-like members. , And a swiveling mass engagement member having a mechanism for engaging and disengaging the pipe member to receive and hold the paper. Conventional pipe-type binders are disclosed in US Pat.
2848 and other references.

[0004] To facilitate reception and holding, the paper to be filed must be properly aligned with the ring or pipe member, properly aligned with the number of holes corresponding to the ring or pipe member, and It must be pre-perforated with a separate punching device that can perform such perforation. As a result, the prior acquisition and use of such punching equipment would make it possible to use ring or pipe type binders on fresh unperforated paper or paper perforated with something other than such punching equipment. It is a prerequisite. In situations where such punching equipment is not available, whether in a conferencing environment such as a lecture or assembly, users of ring or pipe type binders should
It will not be possible to store new paper in them without resorting to manual inaccurate perforations with fingers, pens, pencils and other interim tools.

As a result, such sheets are filed by the user of the binder as damaged or poorly organized, or in many cases are left unfiled and subsequently Vulnerable to loss, damage and other rough handling. In an attempt to solve the problem of keeping the punch mechanism separate from the loose binder as generally described above, various ring binders with perforating functions have been proposed and published wherever relevant. Have been. June 7, 1988,
U.S. Pat. No. 4,749,297 to Roy discloses a ring binder having a piercing dice-like device located below a frame mounted on a central panel section and designed to pierce the ring member when it is opened. Has been disclosed. Such an opening action causes the spring leaf to pivot, causing the punch to pivot towards the hole in the hinge leaf, thereby piercing the paper inserted in the lower part of the binder.

[0006] Due to the (complicated) design, the device appears to be costly from a manufacturing standpoint and susceptible to breakage and adverse operational effects. Moreover, since the location of the components of the device is given below the central panel, repair or corrective action on the device in the event of such an adverse effect appears to be difficult. 1993 AD
US Patent 5 granted to Brands on December 28, 2005
No. 273370 also discloses a ring binder with a perforating device which performs a perforating action again using the opening of the ring member. Such an opening operation causes the frame on which the ring member is disposed to move downward, so that a punch member disposed on the frame is penetrated through the sheet to make a hole. Brand et al. Also disclose devices that do not require such ring members to open. In that device, holes are drilled by pushing the binder device downward. Due to the complex design consisting of a large number of moving parts including (but not limited to) hinges and springs, the device appears to be costly from a manufacturing standpoint and susceptible to breakage and operational harm.

US Pat. No. 5,429,445, issued Jul. 4, 1995 to Un-tae, discloses a binder having a perforation device mounted on a central panel portion of a conventional ring binder. The present invention includes a lump of drilling rods housed within a cover of a ring frame in a conventional ring binder. as a result,
Substantial increase in weight over conventional ring binders,
This results in reduced portability and ease of handling, and higher manufacturing costs. Functionally, the device has the problem that the paper previously held by the ring member hinders the use of the punching device by partially blocking the punching process and subsequent recovery of the newly punched paper. is there.

[0008] Any of the related techniques described above with respect to the ring binder will allow the user to punch holes in the paper, but the fundamental problem with them is the complexity of the design and construction. Embrace. Increased weight and reduced portability, difficult and cumbersome usage, and possibly higher manufacturing costs. A pipe-type binder having a perforating function has not been proposed so far.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a loose-leaf binder which can be used for punching and receiving and storing paper in an environment where a conventional loose-leaf cannot be used because there is no separate punching device. It is.

[0010] Another object is to provide a loose-leaf binder having a perforating mechanism in a design and configuration utilizing the current configuration and components of conventional loose-leaf binders to benefit our benefit.

Yet another object is to provide a loose-leaf binder having a perforating mechanism with no or minimal added moving parts and minimal design and configuration.

It may be further formed as a separate embodiment with one or more certain other elements and components included by the ring binder embodiment described above, such as the hinge 7, and the chipstopping partition 22.

FIG. 11A is a cross-sectional view of an embodiment of the present pipe binder with the cover open. FIG.
(B) is sectional drawing of the Example of this pipe binder with the cover closed.

In operation, various embodiments of the present pipe binder require the same steps as in the case of the ring binder in perforating paper, in which the front cover 1 and the back cover 2 are opened. Then, the corners of the sheet are inserted into the trapezoidal member 41 and trimmed, and the front cover 1 and the back cover 2 are closed. Such an operation causes the punch member 5 to face the inserted paper and pass through the paper to form the cut holes 21.
Into it, while at the same time creating a circular punch there. Chips generated by the perforation of the paper in this manner are trapped in the partition 22. The front cover 1 and the back cover 2 are opened, and the perforated sheets are collected.

The present invention is not limited to the above embodiment. Additional advantages and modifications will readily appear to those skilled in the relevant art. Therefore, the present invention in the broader phase
It is not limited to the specific details and illustrated examples shown and described herein. Therefore, it is not intended that various modifications be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.

The present invention provides a loose-leaf binder that can be used to punch and receive and store paper in an environment where a conventional loose-leaf binder cannot be used because there is no separate punching device. The present invention addresses the attendant disadvantages of ring binders, such as those disclosed in the related art with perforating devices, such as complexity of design and construction, resulting increased weight and reduced portability, cumbersome use, and product. Probably higher manufacturing costs, which rebound to the price of the user, so that the user can do so.

The present loose-leaf binders differ significantly in design and construction in that they make the best use of the current configuration and elements of conventional loose-leaf binders, whether ring or pipe. Because the perforation function of the binder described in the related art is realized by the addition of many moving, heavy and / or complex parts, the perforation capability of the loose-leaf binder is essentially that of both the cover and the ring or ring. This is because it can be realized by using pipe members. The simplicity of design provides various other advantages described above, including, but not limited to, reliability, light weight and portability, ease of use, and ease of manufacture at low cost.

While the foregoing and previous description contains numerous specifics, these should not be construed as limitations on the scope of the invention, but as exemplifications of selected embodiments of the invention.
The scope of the invention should, therefore, be determined not by way of example, but by the appended claims and their legal equivalents. For example, the punching member may be modified to be included in other forms of loose-leaf binder, if such a type is provided at the point of contact between the cover and the member or members holding the sheet, directly or indirectly. If you have The punch member may have a shape other than a cylinder, for example, such that it will have an elliptical, triangular or star shape when drilled. In addition, the size and shape of the rings, pipes and other document holding members, and the size and shape of the binder cover can be varied without departing from the scope of the invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the specific examples given.
