Plastic Clip On
A clip binder to hold sheets includes a flexible housing which includes a top section including an aperture, a bottom section, a side section to connect the top section with the bottom section and an upwardly extending rod mounted on the bottom section. The side section includes a first curved section, a first sloping section connected to the first curved section, a second curved section connected to the first sloping section, a second sloping section connected to the second curved section and a third curved section connected to the second sloping section and the bottom section.
The present invention claims priority under 35 USC section 119 based on a provisional application 60/852,909 filed Oct. 18, 2006.
FIELD OF THE INVENTIONThe instant invention relates generally to mechanisms of loose leaf binders and particularly to a binder assembly device for quickly and easily binding sheets such as papers to create an instant booklet or presentation file.
BACKGROUND OF THE INVENTIONRing binders are well-known tools for storing, displaying and organizing paper and other similar materials and are useful in a variety of settings; for example, in schools and offices. Ring binders are produced in many different shapes, styles and sizes for both aesthetic and functional purposes. The size is usually dependent upon the diameter of the ring closures, non-limiting examples include, ring closures of a half-inch, one inch, one and a half inches, 2 inches, 3 inches, 4 inches and 5 inches in diameter. Additionally, the rings can be crafted into various shapes for different purposes, non-limiting examples include, D-ring and continuous curvature.
While binders can be crafted in a variety of shapes, styles and sizes; they all generally share the same common binder ring mechanism. This mechanism is usually spring-loaded and when engaged will quickly and efficiently clamp together to join opposing sides of the rings of the binder. However, due to the pressure exerted on the spring mechanism from repeated use, part and/or all of the ring and/or rings move out of alignment and cease to clamp tightly together. The ease of sifting through the contents of the ring binder is impaired and items may be lost from the binder due to slipping out from misaligned rings. This misalignment of the rings essentially destroys the function of the binder.
DESCRIPTION OF THE PRIOR ARTU.S. Pat. No. 4,690,580 discloses a ring binder mechanism of the type referred to wherein the ring portions are reliably adjusted on all sides in their closed position even with heavy loading and are secured against opening of the ring closure by displacement of the ends of the ring portions.
U.S. Pat. No. 5,765,956 discloses a device for perfected closure of the mechanism having flat rings for containers of mobile sheets (binders). The device comprises rings and screws which are formed with a single presswork operation together with a strip to be placed at the disposal of the user. The latter with simple coin screws within suitable orifices formed on the strip, the latter being fixed to the internal surface of the folder. There is also provided that each ring may be closed simply by causing projections which are formed on the base of each ring to penetrate within shaped grooves, the latter being formed at the opposite end of the same ring, an operation which is easy due to the elasticity of the material which constitutes the rings.
U.S. Pat. No. 7,125,190 discloses a ring binder assembly device that can both prevent misalignment of binder rings and repair binder rings which have become misaligned. The device of the preferred invention is both a resilient and flexible structure which substantially surrounds the existing binder rings. The device is comprised of at least two hollow tubes of continuous curvature which engage upon closing of the rings to form a single unit. The hollow tubes are sized to substantially cover the entire underlying binder ring and each can be formed as unitary or segmented elements. Since it has been theorized that a funnel-shape can guide a smaller object to a specific point, one end of one of the hollow tubes is molded into a funnel-shape. Through use of this funnel-shape, the device of the instant invention renders it possible to guide one part of a ring to the other part of the ring, thus preventing misalignment and forcing the rings to realign properly should they be out of place.
Standard folders, binders, report covers and other types of paper filling products can be cumbersome, bulky, flimsy or difficult to use. Many devices are simply suited to holding a single type of paper and do not provide effective binding to pages with other dimensions.
SUMMARYThe clip binder provides a user with the quick and easy way to bind papers and create an instant presentation. The design of a clip binder of the present invention provides an inexpensive way to maintain the organization of papers for home, office or school. The user can easily create a file by using a single, durable binding product that is easy to attach and simple to use. The present invention will be used by users of all ages for their binding needs, and the users will appreciate the simplicity of this device.
A clip binder to hold sheets includes a flexible housing which includes a top section including an aperture, a bottom section, a side section to connect the top section with the bottom section and an upwardly extending rod mounted on the bottom section.
The side section includes a first curved section, a first sloping section connected to the first curved section, a second curved section connected to the first sloping section, a second sloping section connected to the second curved section and a third curved section connected to the second sloping section and the bottom section.
The invention may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which, like reference numerals identify like elements, and in which:
The upwardly extending rod 102 could have a rectangular, triangular or any other suitable cross section and may have an inwardly sloping end to facilitate the cooperation with the flexible housing 104 and the sheets of the user. The flexible housing 102 includes an aperture 112 to accept the upwardly extending rod 102.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed.
