1. Field of the Invention
The present invention relates to a notebook, and more particularly to a notebook device having integral binder members that are not required to be manufactured separately.
2. Description of the Prior Art
Typical notebooks, organizers, or the like comprise two cover sheets, and a binder device or loose-leaf holder disposed between the two cover sheets, to detachably retain sheet or paper members between the two cover sheets.
For example, U.S. Pat. No. 5,704,646 to Tzeng discloses one of the typical organizers and also comprises a binder device or loose-leaf holder disposed between two cover sheets, to detachably retain sheet or paper members between the cover sheets.
Normally, the binder devices or the loose-leaf holders are made of metal materials, and are required to be manufactured separately and then required to be secured or assembled between two cover sheets, such that the manufacturing cost is greatly increased.
In addition, the binder devices or the loose-leaf holders that are made of metal materials may include a great weight and may also greatly increase the weight of the typical notebooks, organizers, or the like.
U.S. Pat. No. 5,553,959 to Feldman et al. discloses a typical notebook system which comprises a number of disk fastening members to detachably secure or retain two cover sheets and a number of sheet or paper members together. However, the disk fastening members are separately manufactured and are required to be assembled onto the cover sheets and the sheet or paper members, and may be easily disengaged from the cover sheets and the sheet or paper members.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional notebooks or organizers or the like.
The primary objective of the present invention is to provide a notebook device including integral binder members that are integrally formed between the cover sheets and that are not required to be manufactured separately and that are not required to be further assembled onto the notebook device.
The other objective of the present invention is to provide a notebook device including integral binder members that may be easily and quickly formed between the cover sheets by mass production processes.
In accordance with one aspect of the invention, there is provided a notebook device comprising a top cover sheet member, a bottom cover sheet member, and an intermediate connection member integrally coupled between the top and the bottom cover sheet members with folding lines respectively, for allowing the top and the bottom cover sheet members to be folded relative to the intermediate connection member and to be folded toward each other. The intermediate connection member includes one or more bars coupled between the top and the bottom cover sheet members with the folding lines respectively, and includes one or more straps integrally coupled between the top and the bottom cover sheet members with the folding lines respectively and having a length greater than that of the bars, to form one or more binder members between the top and the bottom cover sheet members.
The binder members and the straps include a length greater than that of the bars and are thus curved and convex relative to the bar of the intermediate connection member.
The intermediate connection member includes one or more lateral cutting lines formed therein to form the straps and one or more second straps between the top and the bottom cover sheet members, and includes a longitudinal cutting line formed in each of the second straps, to form the bars and a second bar in each of the second straps.
The bars of the second straps include a length greater than that of the second bars of the second straps. The second strap includes at least one coupling portion provided between the bar and the second bar in order to secure the bar and the second bar of the second strap together.
The bar of the second strap includes a first segment secured to the second bar of the second strap, and includes a second segment extended beyond the second bar of the second strap, and a reinforcing band secured to the second segment of the bar of the second strap.
One or more sheet members may further be provided and attached to the intermediate connection member and retained between the top and the bottom cover sheet members with the binder member.
Each of the sheet members includes at least one opening and at least one passage formed therein and communicating with each other, to detachably receive the binder member, and to detachably secure the sheet member between the top and the bottom cover sheet members with the binder member.
Each of the openings of the sheet members includes a width greater than a width of the binder member, and includes a depth smaller than the width of the binder member.
Each of the passages of the sheet members includes a width smaller than a width of the binder member, to prevent the binder member from being disengaged from the sheet member.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
For example, the intermediate connection member 40 is integrally coupled between the top and the bottom cover sheet members 20, 30 with bending or folding lines 21, 31 respectively (
One or more binder members 60 are formed or provided on the intermediate connection member 40, and/or integrally coupled between the top and the bottom cover sheet members 20, 30 with the folding lines 21, 31 respectively, which will be described in details hereinafter, in order to retain one or more sheet members 50 within the notebook or between the top and the bottom cover sheet members 20, 30.
As best shown in
It is preferable that the oval-shaped openings 51 of the sheet members 50 include a width slightly greater than the width of the binder members 60, and a depth slightly smaller than the width of the binder members 60, for retaining the sheet members 50 to the binder members 60, and for allowing the sheet members 50 to be smoothly turned relative to the binder members 60.
The passages 52 of the sheet members 50 include a width smaller than the width of the binder members 60, for prevent the sheet members 50 from being disengaged from the binder members 60. It is to be noted that the sheet members 50 are normally made of paper materials, plastic materials, or the like, and are flexible, such that the binder members 60 may be engaged into the oval-shaped openings 51 of the sheet members 50 via the passages 52 of the sheet members 50 when the sheet members 50 are slightly bent relative to the binder members 60.
As shown in
As best shown in
The intermediate connection member 40 of the planar sheet member is then cut or formed with one or more transverse or lateral cutting lines 41, 42 in order to form one or more coupling straps 43, 44 in the intermediate connection member 40. The straps 43, 44 of the intermediate connection member 40 are integrally formed and coupled between the top and the bottom cover sheet members 20, 30 with the folding lines 21, 31 respectively, or the top and the bottom cover sheet members 20, 30 may still be coupled together by the straps 43, 44 of the intermediate connection member 40 at this moment.
As best shown in
As also shown in
For example, as shown in
After the straps 43 are cut, and after the bars 47 have a portion secured onto the bars 46, the straps 44 may include a length greater then that of the bars 47, and thus may be curved or convex relative to the intermediate connection member 40, best shown in
It is preferable that the top and the bottom cover sheet members 20, 30 and the intermediate connection member 40 are formed or manufactured from plastic or synthetic materials, for allowing the bars 46, 47 of the straps 43 to be solidly secured together by such as the welding processes, and thus for allowing the binder members 60 to be quickly formed on the intermediate connection member 40 or between the top and the bottom cover sheet members 20, 30 by mass production processes.
Similarly, as shown in
Referring again to
In operation, as shown in
It is further to be noted that, as best shown in
Accordingly, the notebook device in accordance with the present invention includes one or more integral binder members that are integrally formed between the cover sheets and that are not required to be manufactured separately and that are not required to be further assembled onto the notebook device, and that may be easily and quickly formed between the cover sheets by mass production processes.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
