Description

  The present invention relates to a binder-type notebook structure, that is, a so-called leather cover system notebook structure.

When manufacturing a system notebook, as shown in Japanese Utility Model Publication No. 30-1110, the simplest structure is “a support portion on the top of two long thin plate sandwiching pieces 1 and 2 having roots attached in a undulating manner. 3 and 4 are provided, the cover 7 is sandwiched between both sandwiching pieces, the thin plate sandwiching piece 1 is inserted into a number of binding rings 6 of the notebook paper 5, and the top support portion 3 is exposed to expose another thin plate sandwiching piece. The structure of the notebook which is detachably fitted to the support part 4 provided on the top of 2 is devised.
However, when the thin plate sandwiching piece 1 is made of metal, the metal fitting is exposed and there is a risk of hurting the hand.

After that, as a practical thing, the one where the washer of the refill binding metal fitting was attached to the inner surface side of the back cover part of the cover body appeared. For example, the utility model registration request in Japanese Utility Model Registration No. 3073617 (Patent Document 1 to be described later) includes: “Cuts 5 and 6 are provided in the vicinity of the top and bottom edges on the inner surface side of the spine cover 2. After the peripheral edge of the cover body 1 is sewn, the washer 7 of the refill binding metal fitting 3 is inserted between the outer cover 11 and the lining 4 in the spine cover 2 of the cover body 1 through the cut edges 5 and 6. It is manufactured by assembling the metal fitting main body 12 of the refill binding metal fitting 3, and the length from the top to the ground in the spine cover portion 2 of the cover body 1 is sewn and the back cover portion 2 of the cover body 1 is sewn. Is a system notebook characterized in that it is set substantially equal to the entire length of the refill binding fitting 3 in the longitudinal direction. In addition, as a similar system notebook, Japanese Patent Laid-Open No. 2001-33476 discloses “sewing the peripheral part of the cover body 1 provided with the cut edges 5 and 6 in the vicinity of the top and bottom edges on the inner surface side of the spine cover part 2. After that, the washer 7 of the refill binding metal fitting 3 is inserted between the outer cover 11 and the lining 4 in the spine cover portion 2 of the cover body 1 through the cut edges 5 and 6, and the fitting main body 12 of the refill binding metal fitting 3 is inserted into the washer 7. The length from the top to the ground in the spine cover portion 2 of the cover body 1 is set to be substantially equal to the total length in the longitudinal direction of the refill binding metal fitting 3. "System notebook" is disclosed.

In any of these devices, the washer 7 of the refill binding metal fitting 3 is thinned and the thin washer 7 is embedded inside the spine cover. However, since the system notebook having such a structure uses a curved washer of an existing refill binding metal fitting from the viewpoint of cost effectiveness, this washer becomes an obstacle when the peripheral portion of the cover body is sewn. Therefore, it is necessary to increase the distance from the washer to the sewing portion at the edge of the back cover portion of the cover body, which increases the size of the cover body and is inconvenient for carrying. In addition, this curved washer is practically fixed to the refill fitting, and moves in conjunction with the movement of the refill fitting, which makes it inconvenient to open and close the ring by operating the lever. was there.

Therefore, in order to reduce the size of the cover body and to provide a compact and portable system notebook, in the scope of the utility model registration request of the utility model registration No. 3073661 (patent document 2 described later) "The washer of the refill binding metal fitting 4 which has the claw pieces 8 and 9 at both ends and is substantially the same as the length from the top to the ground of the spine cover 3 in the cover 1 by sewing the peripheral edge of the cover 1 5 is wrapped around and covered with an exterior material 7 such as leather, and the washer 5 covered with the exterior material 7 is overlapped on the outer surface side of the back cover portion 3 of the cover body 1. Claw pieces 8 provided at both ends of the washer 5 by superimposing the metal body 6 of the refill binding metal fitting 4 having a length substantially equal to the length from the ground to the ground on the inner surface side of the spine cover 3 of the cover 1. , 9 from the outside of the top and bottom edges of the back cover 3 Planner "has been proposed is bent to the inner surface of the paper 3, characterized in that secured in hooked to the ends of the fitting main body 6.

However, this system notebook also uses the existing curved washer of the refill binding metal fitting from the viewpoint of cost effectiveness, and there is a risk that the washer 5 is thin and the hand is cut. Therefore, “a leather exterior material 7 having a length substantially equal to the overall length of the washer 5 is prepared, and the exterior material 7 is wrapped around the washer 5 so that the outer surface of the washer 5 except for the claw pieces 8 and 9 is the exterior material. 7 ”(paragraph 0007 of the same publication). However, the cover 1 is not sufficiently restrained only by fitting the exterior material 7 such as leather into the concave portion of the leather back cover 3, and even if the refill binding metal 4 and the washer 5 are fixed to each other at first. When used for a long time, there remains a problem that the fastening portion of the washer 5 is loosened and wobbles to the left and right. Further, since the washer 5 is thin and easily deformed, there is a risk of damaging the user's hand, and there is an inconvenience that the exterior member 7 must be wound around the washer 5 for use.

Utility Model Registration No. 3073617 Utility Model Registration No. 3073661

  The present invention has been made in view of the above problems, and while using the curved washer of the existing refill binding metal fitting, the back cover plate, the back surface of the ring type metal fitting, and the leather cover are brought into surface contact. The leather cover acts as a cushion and the lever is operated to open and close the ring so that it is safe for the user and provides a notebook structure for the leather cover that will not be torn even if the leather is thinned. For the purpose.

  As means for solving the above-mentioned problems, the binder-type notebook structure of the present invention includes a ring-type metal fitting having a plurality of binding rings and clasps at both ends, a leather cover, and a standing claw at a position facing the clasps. In an elongated plate provided with a piece and a binder-type notebook structure in which the retaining hole and the standing nail piece are fitted, the elongated plate is made of a chamfered spring iron alloy or copper alloy. The metal plate has a width and length substantially the same as the width and length of the metal fitting and a thickness of 0.8 to 3.0 mm, and the standing claw piece is fixed by welding or soldering. And

Preferred embodiments of the present invention are as follows.
The cover is characterized in that a push-type groove parallel to the longitudinal direction of the plate is provided on the surface side of the narrow elongated book. Further, the iron alloy is steel containing 0.3% to 2% carbon. The copper alloy is beryllium copper. The thickness is 1.0 to 2.5 mm.

In the present invention, the elongate plate is made of a spring-like iron alloy or copper alloy because the elongate plate needs not to be deformed in order to press the ring-shaped metal fitting on the elongate plate when opening the plurality of binding rings. . The spring-like iron alloy includes stainless steel and copper iron alloy. This is because the shape of the elongated plate can be maintained even when used as a notebook for several years. Examples of spring-like copper alloys include beryllium copper, phosphor bronze, and white. Furthermore, a noble metal such as gold, silver, or platinum can be wet / dry-plated on one side of the plate, or a top lay or an overlay can be clad on the spring-like iron alloy or copper alloy.

In the present invention, the reason why the elongated plate is shaped to have a thickness of 0.8 to 3.0 mm is that the elongated plate and the ring-type metal fitting have a line contact structure, and a leather cover is interposed therebetween. . The leather cover is elastic and has a poor sliding property with metal, so that the pressing force for line contact can be changed to pressing force for surface contact. For this reason, even if the notebook is opened and closed repeatedly, the elongated plate has a thickness of 0.8 to 3.0 mm, so that an excessive tensile force does not act on a specific portion of the leather cover. The thickness of the elongated plate is set to 0.8 mm or more because it does not hurt the notebook user's hand even if chamfering is performed. Also, the width and length of the standard binder-type notebook This is to give a certain rigidity. In addition, when the elongated plate has a thickness in which the central portion is recessed like a tray, it means the thicker one.

In the present invention, the reason for having the standing claw piece at the position facing the retaining hole of the metal fitting is to fit the retaining hole of the ring type metal fitting. The hole may be a round hole or a notch hole. Since the standing claw piece is firmly fixed to the elongated plate by resistance welding or soldering, the standing claw piece can freely move inside the retaining hole and can cope with the deformation force applied to the notebook. When the standing claw piece is bent into an L shape or riveted to be held in the retaining hole, the two retaining holes and the two standing claw pieces are brought into contact with each other at two points. As a simple fitting means, it is preferable to fold the standing claw piece into an L shape and fit it. In addition, the position facing the retaining hole of the metal fitting is inside the both ends of the plate. The reason for providing the standing claw piece at this position is to prevent the fitting portion between the plate and the metal fitting body from being broken by the vibration even if the refill binding metal fitting is repeatedly opened and closed. For this reason, the standing claw piece is relatively easy to deform and is preferably made of a material which can be easily welded to a plate or a ring-type metal fitting with resistance welding, laser welding or soldering. For example, soft iron, steel, white, brass, etc. can be used. Resistance welding is the simplest welding method.

If you use a binder-type notebook, you will need to repeatedly open and close multiple binding rings. At this time, the elongated plate will not be deformed to 0.8 mm or more, and the fitting structure with standing nail pieces will not come off. It is to make it. The upper limit of the elongated plate is set to a thickness of 3.0 mm because the elongated plate becomes too heavy to be used for a notebook. The thickness of the elongated plate is preferably 1.0 to 2.5 mm, particularly preferably 1.3 to 2.2 mm.

In the present invention, the elongate plate has the same width and length as the ring metal fitting because the elongate plate is used as the back cover of a binder-type notebook. The reason for using a leather cover between the elongated plate and the ring-type metal fitting is as follows. That is, the elongated plate and the ring metal fitting are in line contact via leather. However, since leather is hard to slip against metal, the leather serves as a cushion, and the elongated plate and the leather, and the ring-type metal fitting and the leather are in surface contact. For this reason, even if the retaining hole and the standing claw piece are in point contact, the fixed state between the leather cover and the ring-type metal fitting is more stably fixed by surface contact. In addition, it is more preferable that the elongated plate has a shape similar to the shape of the back surface of the ring-type metal fitting, for example, an arc-shaped cross section in the longitudinal direction, because it can be in close contact with the leather cover though it is expensive.

In the present invention, the reason that the cover is preferably provided with a push groove parallel to the longitudinal direction of the plate on the surface side of the narrow longitudinal book is to make it easy to open even an unused notebook. That is, the leather cover inside the notebook is generally processed so as to shrink more than the front leather cover. This is to prevent an unused notebook from being opened, but at the same time, it is difficult to open the notebook when it is first used. Therefore, the push groove is provided on the outer surface, so that even an unused notebook can be easily opened, and the opening and closing operation of the ring of the ring type metal fitting by the lever becomes easier. Further, even if hard leather is used, the surface contact between the elongated plate and the ring-type metal fitting is further stabilized. That is, even if the notebook is accidentally pulled, the leather cover is prevented from being torn off from the surface contact portion between the elongated plate and the ring-type metal fitting even if the leather cover is thinned.

In the present invention, it is preferable that the iron alloy is steel containing 0.3% to 2% carbon, or that the copper alloy is beryllium copper. This is because it has good characteristics and is familiar to leather, and makes surface contact between the elongated plate and the ring-type metal fitting more stable. As the material of the elongated plate, a lightweight aluminum alloy or titanium alloy can be used, or a nickel alloy may be used. It should be noted that the entire surface of the elongated plate may be plated with platinum, clad with a single gold tape, or inlaid with gold particles.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, preferred embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings, the same or corresponding parts are denoted by the same reference numerals, and redundant description is omitted.

  1 to 3 are views showing an embodiment of a binder-type notebook structure (1) according to the present invention. FIG. 1 is a perspective view for explaining a binder-type notebook structure (1) in a state in which a leather cover (2) is opened, and FIG. 2 is a partially cutaway sectional view taken along line BB in FIG. FIG. 3 is a perspective view showing the standing claw piece fitted in the retaining hole. First, it demonstrates based on these figures.

A binder-type notebook structure (1) comprises a leather cover (2), a binding ring (3) for fastening a paper or plastic refill, a retaining hole (4, 4 ') and levers (5, 5) at both ends. It consists of a ring-type metal fitting (6) with a ') and an elongated plate (7) for the back cover. The elongated plate (7) has a width of 5 mm, a thickness of 2 mm, and a length of 180 mm, and the corners are chamfered. Standing claws (8, 8 ′) having a width of 3 mm, a thickness of 1 mm, and a length of 5.5 mm are resistance-welded to the elongated plate (7) at a position 3 mm from the end face. The standing nail pieces (8, 8 ′) pass through the holes of the leather cover (2) and are fitted into the retaining holes (4, 4 ′) of the ring-type metal fitting (6). The retaining holes (4, 4 ') are obtained by cutting out both ends of a tape-shaped thin plate having an arc cross section in a U-shape. After that, the standing claw pieces (8, 8 ') are bent in an L shape and come into contact with the ring metal fitting (6) at two points, and the elongated plate (7) is fitted. The leather cover (2) has a thickness of 1 mm, and there are two grooves (9, 9 ') on each side of the elongated plate (7), one groove pressed from the front side of the notebook. Is provided.

Although the back surface of the ring type metal fitting (6) has an arc shape, the elongated plate (7) having a rectangular cross section is in contact with the ring type metal fitting (6) through the leather cover (2). ) Becomes the cushion of both and comes into surface contact. For this reason, even if the lever (5, 5 ') of the binding ring (3) is repeatedly pressed to replace a paper or plastic refill (not shown) having a plurality of binding holes on the left side, the elongated plate (7) can serve as a foundation and can apply a pressing force stably. Further, when the two-point contact is loosened, the standing claw pieces (8, 8 ′) fitted in the retaining holes (4, 4 ′) can freely move around in the retaining holes (4, 4 ′). However, since the ring metal fitting (6) is in surface contact with the leather cover (2) due to the cushion effect of the leather cover (2), the ring metal fitting (6) hardly moves. As a result, the movement of the lever (5, 5 ') of the ring-shaped metal fitting (6) is stabilized independently of the elongated plate (7). Therefore, it is possible to replace the paper or plastic refill with peace of mind. Further, even if the end of the leather cover (2) is pulled by mistake, the leather cover (2) is not torn from one place because it is in surface contact with the sandwich structure.

The binder-type notebook structure according to the present invention has the following effects.
Due to the cushioning effect of the leather cover, the ring-type fitting fitted to the elongated plate can be moved many times independently of the elongated plate. For this reason, the leather cover will not be broken even after many years of use. Further, since the elongated plate is not deformed by a normal use method, it can be aligned even if it is a plastic refill as a substitute for the back cover of the notebook. Further, since the elongated plate has a width and a length that are substantially the same as the width and length of the ring-type metal fitting, the lever can be pushed without wobbling the ring-type metal fitting. For this reason, it can be set as the support stand of a ring-type metal fitting at the time of the opening and closing operation | work of several binding rings. Further, since the elongated plate does not deform even when resistance welding or soldering is performed, the elongated plate is not distorted even if the opening and closing operation of the binding ring is performed many times. Further, since the elongated plate is chamfered, even if it is exposed outside the leather cover, the user's hand is not damaged. In addition, since the elongated plate is metal, it is more rigid than the leather cover, and even if a hard leather cover is used, the leather cover can be firmly sandwiched between the elongated plate and the ring type metal fitting. Further, when the push-type groove is provided on the outer surface, it can be easily opened even in an unused notebook, and the opening and closing operation of the ring of the ring-type metal fitting by the lever becomes easier.

It is a perspective view in the state where a leather cover was opened. It is a partially notched sectional view in the BB line of FIG. It is a perspective view which shows the standing nail | claw piece fitted by the retaining hole.
