Object of the Invention
[0001] The present invention describes an assembly which allows adding a cover to a spiral
notebook in order to improve its visual appearance. Furthermore, the assembly can
be easily disassembled, allowing the separation of the spiral notebook from the cover
in a very short time.
Background of the Invention
[0002] Various document binding systems are currently known in the art. Ring-bound notebooks
comprise a long base provided with rings and secured to the inner face of the spine
of a cover. On the other hand, the sheets making up the document have holes corresponding
to the rings of said base. Therefore, by inserting the rings through the holes it
is possible to secure the cover to the document in a fast and simple manner. A drawback
of this assembly is that, if the document is to be separated from the cover, the sheets
will come loose, being able to cause the accidental lost of part of the document.
[0003] Another known system consists of spiral binding, where the sheets making up the document
have a row of small holes through which the spiral is inserted. With this assembly,
the sheets are held in a more secured manner and the document can be read conveniently.
However, the aesthetic appearance of a spiral notebook is unsuitable for certain uses.
For example, since it is not provided with a spine, users do not usually keep them
together with books or catalogues in a bookcase, because not only is it rather unattractive,
but since the spiral notebook does not have of a spine where the title can be annotated,
it is impossible to identify the document without taking it off the shelf.
[0004] The invention described in Korean patent application number
KR-20080083528-A tries to solve the aforementioned problem by arranging means which allow linking
a spiral binding to a cover. To that end, the inner face of the spine of the cover
incorporates a plurality of aligned elements the configuration of which is rounded
at the free end thereof, such that after arranging the spiral of a binding between
said aligned elements, an open hollow tube is arranged longitudinally that is fitted
in the rounded parts of the aligned elements, thereby retaining the spiral.
[0005] However, this arrangement has various drawbacks and deficiencies. Firstly, it is
difficult to put in place because the tube must be fitted into each and every one
of the rounded parts of the elements when it is being placed, there being no means
that allow automatically assuring its correct placement. Secondly, the spiral can
easily come out of place in the event of pulling the cover according to a direction
perpendicular or diagonal to that of the spiral, given that the tube is flexible and
has a longitudinal opening to allow the passage of the web or narrow part of the elements,
so said tube can be removed from the rounded parts. Finally, this securing does not
incorporate retention means that assure the position of the tube in its retention
position in the actual direction of the spiral.
[0006] As a result, the problem of providing a reliable and comfortable assembly that allows
providing a spiral notebook with a cover has not been solved until now.
Description of the Invention
[0007] The preceding problem is solved by means of the assembly described herein, which
allows securing a cover to a spiral notebook in a fast and convenient manner. The
spiral notebook can thus be kept in a bookcase in a manner similar to a book, the
notebook being able to be identified through a title or identifying text on the spine
of the cover. Furthermore, the assembly of the invention allows separating the spiral
notebook from the cover easily if needed.
[0008] The assembly of the invention for securing a cover to a spiral notebook comprises
a base suitable for being secured to a cover and a rod coupled to said base to trap
and immobilize the spiral between base and rod, the cover thus being secured to the
spiral notebook. Both elements are described in greater detail below.
a) Base
[0009] The base is flat and long, and a longitudinal row of rings intended for housing the
securing rod extends from one of its faces. The separation between the rings is such
that the spaces between them allow a spiral to rest longitudinally on the surface
of the base. The base further comprises attachment means for attaching same to the
spine of the cover, preferably holes suitable for the passage of screws, studs, rivets
or the like. The base is preferably made of plastic or the like.
[0010] According to a preferred embodiment, the base also comprises separation means separating
the securing rod in relation to the surface of the base, preferably projections located
on the central line of said surface, and more preferably projections having a rounded
concave shape. On one hand, these projections serve for easily inserting the securing
rod through the rings without getting caught in the spiral, because they serve to
support the securing rod such that there is a space between the rod and the surface
of the base. On the other hand, they limit the play existing between the securing
rod and the rings, such that when the rod is placed it is held as firmly as possible.
[0011] Another preferred embodiment of the invention comprises stop means configured to
prevent the securing rod from sliding along the base when it is housed completely
inside the rings. The stop means are preferably two protrusions located at the ends
of the base and giving way vertically downwards to allow the passage of the securing
rod through the row of rings, and they recover their position when the rod has passed
through to prevent it from sliding longitudinally. For these protrusions to have the
necessary flexibility, they are preferably separated from the base along their entire
perimeter except in a narrow strip. Therefore, when operations to insert the rod through
one of the ends of the base begin, the force exerted by the rod on the protrusion
causes said protrusion to give way vertically downwards, thereby allowing the passage
of the rod.
b) Securing rod
[0012] The securing rod, which is preferably cylindrical, is configured to be housed inside
the row of rings and to thus trap the spiral between the rod and the base. According
to another preferred embodiment of the invention, the securing rod is made of plastic
or the like.

[0013] To complement the description that is being made and for the purpose of aiding to
better understand the features of the invention according to a preferred practical
embodiment thereof, a set of drawings is attached as an integral part of said description,
where the following has been depicted with an illustrative and non-limiting character:

Preferred Embodiment of the Invention
[0014] An example of the assembly of the invention is described below making reference to
the attached drawings. Figures 1a and 2a show respective perspective views of the
base (2) and of the securing rod (8), whereas Figures 1 b and 2b show respective cross-section
views of said base (2) and said securing rod (8). The upper face of the base (2) has
a plurality of aligned rings (3) for housing the securing rod (8). The securing means
(4) for securing the base (2) to the cover (10) are also seen in Figure 1a, in this
example such means are holes for rivets. Several separation means (5) have also been
depicted; in this example such means are projections having a rounded concave shape
distributed along the base (2), where the securing rod (8) will rest once it is located
in its housing. Furthermore, stop means (6) in the form of a protrusion (6), the arrangement
of which can be seen in detail in Figure 1b, prevent the rod (8) from coming out of
its housing once inserted.
[0015] Figure 3 shows in greater detail an end of the base (2) with the securing rod (8).
It can be seen how the protrusion (6) does not allow the rod to come out of its housing
once inserted. However, as described above, this protrusion (6) is provided with enough
flexibility so as to give way vertically downwards during the process of inserting
the rod (8). In this example, this flexibility is achieved as a result of the protrusion
(6) being attached to the base (2) by only two narrow strips (7). It is understood
that the protection conferred by this utility model covers protrusions (6) attached
to the base by one or more narrow strips (7) provided that they serve to achieve the
flexibility described. Figure 4 shows how the spiral (11) is trapped between the base
(2) and the rod (8) once the spiral (11) is suitably located on the base (2) and the
securing rod (8) is inserted.
[0016] The operations of inserting and removing the rod (8) in the base (2) are carried
out as follows. Firstly, the spiral (11) is placed longitudinally on the base (2).
Then the securing rod (8) is inserted, moving the protrusion (6) downwards to that
end, and the rod (8) is slid through the successive rings (3) located along the base
(2), as shown in Figure 5. During this phase, the rod (8) rests on the separation
means (5), thereby preventing its front end from sliding on the surface of the base
(2) and getting caught in the spiral (11) during the process of inserting said rod.
Once the rear end of the rod (8) overcomes the protrusion (6), said protrusion recovers
its position with a click, the rod thereby being trapped in its position, and the
spiral notebook (11) accordingly being secured to the cover (10). If the spiral notebook
(11) is to be removed from the cover (10), one must only press the protrusion (6)
downwards with a finger and remove the rod (8). Figure 6 shows a detail of a spiral
notebook (11) to which a cover (10) has already been secured.
