Description

  The present invention relates to a structure of a monthly calendar configured by binding upper end binding portions of a plurality of collated calendar pages with a cardboard binding tool.

  Conventionally, as a means of binding the upper end binding portion of a plurality of calendar page booklets constituting a monthly calendar, the upper end binding portion of the booklet is pressed with a metal binding bracket and wound, so that a plurality of calendar pages are bound. A structure in which a booklet is fixed integrally is widely known.

  However, this type of booklet's upper end binding part is pressed with metal binding fittings and rolled up, so the metal binding fittings cannot be incinerated and cannot be incinerated at incinerators nationwide at the end of the year. This is a problem of pollution due to the large amount of metal binding hardware being fed.

  Therefore, recently, a calendar in which the upper end binding portion of the calendar booklet is bound by a cardboard binding tool that can be incinerated has been widely used. A calendar that binds the upper bound portion of the booklet with this cardboard binding tool also has a plurality of holes in the upper bound portion of the booklet, and a thermoplastic resin adhesive such as hot melt is injected into the hole. It has a structure in which the booklet upper end binding portion and the binding tool are bonded to each other by an adhesive (Patent Document 1) (Patent Document 2), or a plurality of locking protrusions project on one side of a cardboard binding tool. And a structure in which these locking protrusions are inserted into connection holes provided in the upper end binding portion of the booklet and then inserted into a stop hole provided on the opposite side of the cardboard binding tool (Patent Document 3). )It has been known.

Japanese Utility Model Publication No. 6-36885 JP-A-6-262878 Japanese Patent Laid-Open No. 11-32156

  The calendars of (Patent Document 1) to (Patent Document 3) are used instead of a structure in which the upper end binding portion of the calendar booklet is wound with a metal binding fitting, and the upper end binding portion of the booklet is bound to a cardboard through an adhesive. Therefore, it can be said that it is more suitable for incineration at the end of the year than in the case of metal binding metal fittings, but it can be said that it is suitable for quick-drying as an adhesive. Since resin adhesives are used, burning of these resin adhesives generates harmful gases, which becomes a problem as new pollution, and is never an effective improvement measure from the viewpoint of environmental conservation. It has a side that cannot be said.

  In order to eliminate the problems caused by the burning of such an adhesive, the upper end binding portion of the calendar booklet can be bound by a cardboard binding tool without using a resin adhesive. Although a structure is required, the technique of fixing the binding tool to the top edge of the booklet without using any adhesive is extremely difficult, and it is possible to suspend multiple sheets of fine paper stably without deformation and to make a booklet every month. In order to make the structure in which the binding tool is not deformed even when one of the two is pulled down and separated, a very difficult problem must be solved. In particular, the monthly calendar is installed in a room that is visible to the public. However, the top edge of the booklet and the protruding piece for fixing the booklet to the surface of the binding tool are exposed, and the appearance is damaged. It must be structured so that nothing happens.

  As a means for solving the above-mentioned problems in the conventional monthly calendar, the present invention provides the width of the binding piece on the lower side of the binding piece forming the binding tool for binding the upper end binding portion of the calendar booklet. Reinforcing pieces of the same width are arranged in series, and these reinforcing pieces are folded twice inside the binding pieces in the binding tool, so that the binding tool has sufficient strength against the bending force, After inserting a plurality of locking sides provided in one reinforcing piece into a plurality of insertion holes provided in the upper end binding portion of the booklet, into an insertion hole provided between the other binding piece and the reinforcing piece. By inserting it, it is possible to produce a monthly calendar that is beautiful and durable in appearance without using any adhesive.

  The calendar by the paper binding tool according to the present invention is a calendar in which the upper end binding portion of a booklet composed of a plurality of calendar pages is bound by a cardboard binding tool as a specific means for that purpose. A plurality of insertion holes along the upper end binding portion of the booklet are provided at intervals in the lower portion of the binding margin, and the binding tool is attached to both sides of the central folding line along the length direction of the booklet. A binding piece having the same width as the binding margin, and a reinforcing piece that is folded into the inside of the binding piece via a folding line at the lower end of each of the binding pieces. At the position corresponding to the insertion hole of the booklet, there is provided a locking side by two cut lines oriented in a direction perpendicular to the folding line, and the binding piece below including the folding line between the other binding piece and the reinforcing piece. The part has a position corresponding to the insertion hole of the booklet. An insertion hole was provided, and after the tip of the locking side was inserted into the insertion hole of the booklet, it was inserted between the binding piece and the reinforcing piece through the insertion hole provided in the lower part of the binding piece. It is characterized by this.

  In the calendar of the present invention, a reinforcing piece having a width similar to the width of the binding piece is continuously provided on the lower side of the binding piece that forms the binding tool for binding the upper end binding portion of a plurality of calendar booklets. The double-folded reinforcing piece is folded inside the binding piece, so that the binding tool is formed with two sheets of paper on the front side and the back side, respectively, so that the paper binding tool does not use an adhesive. Even so, sufficient strength can be imparted to the bending force in the vertical and longitudinal directions.

  In this case, each reinforcing piece is folded in a V-shaped cross section inside the binding piece via a folding line between the reinforcing piece and the original reinforcing piece with the lower folding line as the center. The force to return to the lower position works, and this force presses both the front and back sides of the booklet top binding part located inside from the outside. It can be clamped and held.

  Also, after inserting a plurality of locking sides provided in one reinforcing piece into a plurality of insertion holes provided in the upper end binding portion of the booklet, an insertion hole provided between the other binding piece and the reinforcing piece. When inserted into the inside, the respective locking edges are clamped and fixed between the binding piece and the reinforcing piece folded in a V-shaped cross section located on both front and rear sides of the booklet upper end binding portion. The top edge of the calendar booklet can be appropriately held by the stop.

  The plurality of locking sides provided in one reinforcing piece are inserted into the inside of the binding piece through the insertion hole in the lower part of the other binding piece after passing through the insertion hole of the upper end binding part of the calendar booklet. Therefore, the latching side is not exposed to the outside even when viewed from the front and rear surfaces, and therefore, a monthly calendar that is beautiful in appearance and durable can be manufactured without using any adhesive.

  Next, the configuration of a preferred embodiment of the calendar according to the present invention will be described with reference to the examples shown in the drawings. FIG. 1 is a perspective view showing the constituent members of the calendar of the present invention. The booklet 1 comprises a calendar page and a cardboard binding tool 2 for binding the upper edge 1a of the booklet 1.

  In the booklet 1, a plurality of insertion holes 3 along the booklet upper end edge 1 a are provided at intervals below the binding portion 1 b that has been lowered from the upper end by the amount of binding by the binding tool. The insertion hole 3 may be a slit having a width that allows a locking side 7 provided in the cardboard binding tool 2 to be described later to pass therethrough, and when it is finally assembled. Furthermore, it is preferable that the width of the groove is not so large that the lower side portion of the width of the groove is not exposed.

  The cardboard binding tool 2 includes binding pieces 4a and 4b having the same width as the binding margin of the booklet upper end binding portion 1b on both sides of the central folding line 2a along the length direction, and lower ends of these binding pieces 4a and 4b. And reinforcing pieces 5a and 5b, which are connected to each other via a folding line 2b and are folded inside the binding pieces 4a and 4b.

  As shown in FIG. 1, at the position corresponding to the insertion hole 3 of the booklet 1 in the reinforcing piece 5a connected to one binding piece 4a, two incision lines parallel to the direction perpendicular to the folding line 2b are provided. By providing 6, the locking side 7 having a width that can be inserted into the insertion hole 3 is provided at an interval, and as shown in FIG. 2, the other binding piece 4 b and the reinforcing piece 5 b in the binding tool 2. Insertion holes 8 through which the locking sides 7 can be inserted are provided at intervals at positions corresponding to the insertion holes 3 of the booklet 1.

In this embodiment, it has been described that the insertion hole 8 is provided on the folding line 2b between the binding piece 4b and the reinforcing piece 5b. However, the insertion hole 8 is not necessarily provided on the folding line 2b. Instead, as shown in FIG. 9, it may be provided on the binding piece 4b slightly above the folding line 2b.

  When assembling the calendar, as shown in FIG. 1, the binding tool 2 is disposed on the binding portion 1 b of the calendar booklet 1. At that time, as shown in FIG. 3 and FIG. 4, the lower reinforcing pieces 5a and 5b of the folding line 2b provided on both surfaces are folded so as to be folded on the back surfaces of the upper binding pieces 4a and 4b. Place from.

  Further, when the reinforcing pieces 5a and 5b are bent, as shown in FIG. 3, the locking side 7 formed by providing the cut line 6 in one reinforcing piece 5a is formed on the upper binding piece 4a. Do not bend the back side, but keep it protruding downward.

  As shown in FIG. 3, after the binding tool 2 is arranged on the binding portion 1b of the booklet 1 in a state where only the reinforcing piece 5a excluding the locking side 7 is bent to the back surface of the binding piece 4a, The side 7 is inserted into the insertion hole 3 provided below the binding portion 1 b of the booklet 1.

  Next, after inserting the locking side 7 into the insertion hole 3 of the booklet binding portion 1b as described above, the tip of the locking side 7 protruding from the back side of the insertion hole 3 is inserted as shown in FIG. It is inserted into the insertion hole 8 provided on the folding line 2b between the binding piece 4b and the reinforcing piece 5b, and as shown in FIG. 5, the locking side 7 is a joint surface between the binding piece 4b and the reinforcing piece 5b. Insert it deep enough to be sandwiched between the two.

  The binding tool 2 for binding the binding portion 1b of the calendar booklet 1 of the present invention has reinforcing pieces 5a and 5b having the same width connected to the lower sides of the binding pieces 4a and 4b via a fold line 2b. 5a and 5b are double-folded inside the binding pieces 4a and 4b by the fold line 2b, so that both sides of the binding tool 2 are the binding piece 4a and the reinforcing piece 5a on the front side and the back side is also the binding piece 4b. The two reinforcing pieces 5b are formed by a thick paper piece having a spring force of a layer folded in a V-shaped cross section, and the booklet binding portion 1b can be bound with a strong force.

  That is, as in the embodiment shown in FIG. 8, if the binding tool 2 is formed of only the binding pieces 4a and 4b that do not have the reinforcing pieces 5a and 5b, the binding pieces 4a and 4b are located on the upper side. Centering on the fold line 2a, a force is applied to spread outward as indicated by an arrow E. Therefore, even if the locking side 7 protruding from one binding piece 4a is inserted through the insertion hole 3 of the booklet binding portion 1b and into the insertion hole 8 of the other binding piece 4b, the binding pieces 4a and 4b are bonded to each other. Because the booklet binding portion 1b is not fixed by the above, the booklet binding tool 2 supports the load of the booklet 1 only by the locking side 7 inserted into the insertion hole 3, and the calendar page is displayed every month. If it is pulled downward so as to be separated one by one, the locking side 7 is pulled out from the insertion hole 8 and the insertion hole 3. A strong binding structure cannot be obtained.

  On the other hand, in the calendar of the present invention, as shown in FIG. 7, the reinforcing pieces 5a and 5b are folded on the back surfaces of the binding pieces 4a and 4b around the folding line 2b. 5b exerts a force of spreading toward the center of the binding tool 2 around the lower fold line 2b, and gives the reinforcing pieces 5a and 5b a force to push each other inward as indicated by an arrow F. It will be.

  As a result, when the binding tool 2 is arranged above the booklet binding portion 1b in this state, the reinforcing pieces 5a and 5b press-contact the front and rear surfaces of the booklet binding portion 1b from both sides, so that the locking side 7 Is inserted sufficiently deeply into the insertion hole 8 formed in the opposite folding line 2b via the insertion hole 3 of the booklet binding portion 1b, the reinforcing pieces 5a and 5b press the booklet binding portion 1b from both sides. Thus, the booklet binding portion 1b can be bound only by the cardboard binding tool 2 without using an adhesive, and sufficient strength can be imparted as a binding tool.

  Further, when the locking side 7 is sufficiently inserted into the insertion hole 8 formed in the opposite folding line 2b through the insertion hole 3 of the booklet binding portion 1b, as shown in FIG. Since the stop edge 7 is sandwiched and held between the binding piece 4b and the reinforcing piece 5b, even if the calendar page is pulled downward to separate the calendar pages one by one, the locking edge 7 is reinforced with the binding piece 4b. It is tightly sandwiched between the pieces 5b and is not pulled away from between the binding pieces 4b and the reinforcing pieces 5b, and the fixing side 7 has a sufficient fixing strength without using an adhesive. it can.

  In the calendar of the present invention, the locking side 7 for connecting the binding tool 2 and the booklet 1 is inserted into the insertion hole 3 of the booklet binding portion 1b after protruding from one binding piece 4a, and the binding portion After protruding from the insertion hole 3 of 1b, it is inserted into the inside of the binding piece 4b through the insertion hole 8 between the binding piece 4b and the reinforcing piece 5b on the opposite side, and is completely invisible from the front side and the back side of the calendar booklet 1. Therefore, the appearance as a product is good, practical, and since no adhesive is used, there is an advantage that it can appropriately cope with environmental problems.
