Description

 The present invention relates to a binding of a construction in which an engagement means for engaging the interior of the folded base of a book is provided to thereby bind the book and, more particularly, it relates to improvements to a binding of a construction where upper and lower support bases protrude inward, upper and lower ends inside the back and a number of engagement blades protrude, in elevation, toward the 'interior' at a predetermined interval of internal surfaces facing the respective bases, thereby connecting the interiors of the folded base of a book to the engagement blades to connect the book.

 A conventional binding of this type has so far been constructed with detachable hairpin connectors, attached directly to the upper and lower ends inside the back portion of the binding in its engagement means .

Then, when the connectors were attached to both ends of the binding, the connectors were simultaneously engaged at the upper and lower ends inside the folded base of a book, thereby binding the book. With this construction thus composed, other fixings were necessary to prevent the connectors in the shape of hairpin from being accidentally removed and moreover to fix the connectors without play. As the connectors were individually independent in the construction, it was difficult to handle and they could also get lost.

 A conventional binding has also been proposed, of a construction in which the engagement means consisted of one or more long rods. Running between the upper end and the lower end inside the portion of the back of the binding. Since in this construction the engagement rods were long, they posed problems from the resistance point of view and a book bound by means of this binding was easily damaged and was also difficult to handle, which was a drawback.

 The present invention therefore relates to a binding in which all the above-mentioned drawbacks of conventional binding can be eliminated and the construction of which can be simple.

 Another object of the present invention is an improved binding in which a book can be efficiently bound without any play.

 Another object is an improved binding that can be easily manipulated to bind a book.

The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating several embodiments of the invention and in which

 The present invention will now be described in more detail with reference to the preferred embodiments shown in the accompanying drawings. Figure 1 shows a perspective view of the binding of the present invention and Figure 2 shows a perspective view of the used state of the binding shown in Figure 1. In Figures 1 and 2, the reference numerals 1 and 1 'represent the covers of the binding and 2 represents the portion of the back. Support bases 3 and 3 'project inwards, respectively, from the upper and lower ends, inside the back portion 2. Engagement pins 5, 5', 5 ", ... and 6, 6 ', 6 ", ... are erected, at predetermined intervals, in pairs. on the internal facing surfaces 4 and 4 'of the respective support bases 3 and 3'. The lower support base 3 'is fixed securely but the upper support base 3 extends in one piece 7 forming leaf spring in the same direction as the engagement pins 5, 5 ', 5 ", from the bottom of the support base 3. When the leaf spring part is inserted into an insertion hole 8 formed at the upper end of the back portion 2 inside the binding, the base 3 can be formed mobile in height. The reference numbers 13 illustrate stop plates. It should be noted that the mobile support base can be formed on the lower side instead of the upper side and that the two upper and lower support bases can be formed movable.

 An engagement means 9 of the binding of the present invention thus consists of support bases 3 and 3 'of which at least one is movable and engagement pins 5, 5', 5n, ... and 6, 6 ', 6 "...

 The operation of the binding of the present invention used for a book will now be described with reference to Figure 2. The lower end of the folded base 11 inside a book 10 is in engagement with the spindle. engagement 6 'of the support base 3', the movable support base 3 is then displaced in height, upwards, and then downwards, and the engagement pin 5 'is engaged in the upper end of the folded base 11 inside the book 10. In this way, the book 10 can be connected to the binding. When book 10 is removed from the binding, the reverse sequence of the above operations can be performed.

 Figure 3 shows another preferred embodiment of the binding of the present invention. The leaf spring part 7 of the movable support base 3 is curved to form upper and lower parts 7a and 7b and a packing member 12 is fixed to the surface of the curved side of the lower part 7b so that the packing member 12 and the external surface of the lower part 7b are displaced, in height, while they are in contact with the internal surface of the insertion hole 8. With this construction, the play of the support base 3 can be even more effectively prevented in comparison with the case where there is only one piece forming a leaf spring.

 Note that the engagement pins 5, 5 ', 5 ", .., can be moved by tilting around the curved part in the same form as the support base 3 shown in Figure 3, although this does not It is preferable, in this case of the support base thus constructed, to form, in position, a protuberance to prevent the free movement of the support base in the insertion hole 8.

 FIGS. 4A to 4C show side and front views of engagement pins of various types, FIG. 6A shows a shape identical to that shown in FIGS. 3 to 5, FIG. 4B shows an engagement pin 5a substantially curved in U in a rod, and FIG. 4C shows an engagement pin 5b formed in a converging part.

 For the above description, there is provided according to the present invention a binding which comprises an engagement means 9 in engagement with the interior of a folded base 11 of a book 10 having the folded base 11 for connecting the book 10 by the engagement means 9, support bases 3, 3 'at least one of which is movable in height and where the engagement means 9 protrude inward from the upper and lower ends of the back portion 2 inside the binding, and engagement pins 5, 5 ', 5 "and 6, 6', 6" ..., erected in pairs from the two internal surfaces opposite 4 and 4 'of the respective support bases 3 and 3', where the mobile support base 3 is moved in height, the engagement pins 5, 5 ', 5 ", .. and 6, 6', 6" ...

formed in pairs thus being in engagement with the upper and lower ends of the support base 11 inside the book 10 to thereby bind the book. Therefore, like the engagement pins 5, 5 ', 5 ", ...

and 6, 6 ', 6 ", ... are not directly manipulated when connecting book 10 but that book 10 can be linked as described above by the elevation movements of the mobile base 3 when connecting book 10, the binding according to the invention can be extremely simple to handle, thus eliminating the drawbacks and disadvantages of conventional binding.

Furthermore, the binding of this invention offers a simple construction and makes it possible to effectively eliminate the play when binding the book 10.

 Figure 5 shows another preferred embodiment of the binding according to the present invention and Figure 6 shows the front view of this embodiment of the binding to describe the operation of this binding.

In Figures 5 and 6, a number of engagement blades 15, 15, ... protrude from the inner surface 4 of the support base 3. Furthermore, the engagement blades 15, 15, .. protrude so as not to be of uniform protruding length but to extend in a variable manner. In the embodiment shown in Figures 5 and 6, the engagement blades 15, 15, ... are aligned so as to be alternately protruding over an equal protruding length. It should be noted that the engagement blades 15, 15, ... may not always be alternately protruding at an equal length of protrusion but may be protruding irregularly, or else they may be all protruding at different lengths of protrusion, and may consist of several groups of protruding dimensions. It should also be noted that the engagement blades can also be arbitrarily aligned. It should also be noted that the engagement blades 15, 15, ... may not be limited only to the shape of the sector shown but may have any shape such as semi-circular, rod-shaped, other than these shapes or in combination of these shapes so that the protruding lengths can be variable.

 It should also be noted that the structure of the engagement blades can be formed from those of a single support base and can also be formed from those of two of the upper and lower support bases in the spirit and framework of this. invention.

 The operation of this embodiment of the binding will now be described with reference to FIG. 6. Books 24, 25, 26 can be bound in the same manner as the conventional binding. In the case of a binding of this embodiment, only the engagement blades 15 of the largest protruding length are initially contacted by the books 24, 25, 26 by pushing the support base 3 and then begins the insertion in books. In this case, a relatively large resistance is produced on the engagement blades due to the resistance to static friction of the blades at the initial contact time, but when the engagement blades begin to fit into the books, resistance dynamic friction is produced at the blades and as a result becomes relatively weak.The shortest engagement blades are then contacted by the books in this state. Consequently, this makes it possible to weaken the resistance to static friction of the engagement blades in comparison with the case where all of the engagement blades are simultaneously contacted by the books, thus facilitating the insertion of the engagement blades into the books.

 As described above, there is provided, according to the present invention, a binding of another embodiment which comprises support plates 3, 3 'projecting downward from the upper and lower ends of the portion back inside the binding and a number of engagement blades 15, 15, ..

projecting at a predetermined interval from the two facing internal surfaces 4, 4 'of the respective support bases 3, 3' so that the engagement blades 15, 15, ... are engaged inside books 24, 25, 26, at the folded bases of the books to connect the books 24, 25, 26 where the protruding lengths of the engagement blades 15, 15, ... are of variable shape. Therefore, like the blades engagement 15, 15, ... are sequentially contacted in the sequence of their lengths protruding into the books at the time of the insertion of the protruding blades into the books to insert them into the books in several stages, the static resistances and Frictional dynamics can be dispersed and weakened compared to the case where all the engagement blades have so far been simultaneously contacted with the books and then simultaneously inserted into the books. In this way, the books 24, 25, 26 can be easily connected with a light force and as a large force is not applied to the engagement blades according to the present invention for binding the books, they are not damaged . This effect can be particularly remarkable in the case where a certain number of books are bound by the binding of this invention.
