Description

[Detailed explanation of the idea] Industrial applications The present application relates to a paper clipper for holding documents and the like.

BACKGROUND TECHNOLOGY Conventionally, a presser member is provided at the front and rear positions of a base plate and is moved up and down in parallel by a crankshaft, and at the center of the base plate, a shaft is inserted between a claw plate and a wall plate formed by cutting and raising. Then, the base end of the handle is rotatably attached to this, and a coil spring is inserted into the handle, one end of the coil spring is extended and engaged with the groove in the handle, and the other end of the coil spring is inserted into a crank shape. For example, a paper clipping device constructed in 1987 is a paper clipping tool which is constructed so that the paper can be held between the base plate and the presser member by bending the crank part to attach the crank part to the presser member and pushing down the handle against the spring. It is publicly known from Publication No.-25679 and the like.

By the way, the base plate and wall plate in this configuration are
It is integrally formed by bending a single metal plate into an L shape, and an engagement hole is provided at one end of this wall plate, and the handle is rotated into the engagement hole against a spring. When the locking piece is in the locked state, the locking piece provided on it is locked, but since the springs used for this generally have extremely strong elasticity, the locking piece is locked when the locking piece is locked. A strong lifting force acts on the base plate, and a torsional force is applied to the base plate between this force and the presser member pressed downward, causing distortion in the base plate. Therefore, conventionally, when attaching a paper clip to the inner surface of the back cover, the base plate is fixed to the inner surface of the back cover with rivets, etc., with the handle in the unlocked state with the base plate in a horizontal position. Next, the handle was locked into the engagement hole of the wall plate, the front cover was closed, and in this state the product was packed in a cardboard box or the like.

Problems to be solved by the invention By the way, according to the conventional configuration, a paper clip whose handle has been locked during the manufacturing process can be changed to the unlatched state by first releasing the handle from the locked state. After attaching the base plate to the inside of the back cover,
Since it is necessary to lock the handle, not only is it time-consuming to make the binding cover, but also the back cover is distorted when the base plate is stuck, that is, when it is stored, so it is difficult to hold the binding sheet of that length. There were inconveniences such as a decrease in quantity and a loss of appearance.

Means for Solving the Problem Therefore, in the present application, by rotating the handle, the holding member supported by the crankshaft is lowered against the spring, and in this state, the locking piece provided on the handle is moved to the base. In a paper clipping device that is configured to hold a paper sheet between a base plate and a pressing member by engaging an engagement hole provided in a wall plate of a plate, when the handle is in a locked state, the base plate To provide a paper clipping device characterized in that the length of the distortion acting on the paper clip is applied to the base plate in advance in a direction to eliminate the distortion,
This solves the above-mentioned inconvenience.

Function When the handle is rotated against the spring and the locking piece is locked in the engagement hole of the wall board,
Distortion occurring in the base plate between the locking portion and the holding member is eliminated, and the base plate becomes horizontal when the handle is locked. Therefore, in this state, the base plate can be fixed to the inner surface of the back cover.

Example Embodiments of the present application will be described in detail below with reference to the drawings.

Reference numeral 1 designates a base plate, one edge of which is bent at right angles to form a wall plate 2, and this base plate 1 has claw plates 3 cut and raised at three places in the longitudinal direction to meet the wall plate 1. They are set up in parallel. A shaft 4 is inserted between the central nail plate 3a of these nail plates 3 and the wall plate 2,
The front end of the shaft 4 has a large-diameter head, and the rear end has a stop 5 formed by crushing the shaft 4.
This prevents it from coming off. The base end of a handle 6 is rotatably attached to the shaft 4, and a conical coil spring 7 whose diameter gradually becomes smaller in the distal direction is rotatably fitted in the shaft 4 with its small diameter portion. The large-diameter end of the coil spring 7 extends and is locked in the groove of the handle 6, and the small-diameter end of the coil spring 7 extends to hold the middle arm 8. At the same time, a forearm 9 bent into an L-shape is formed at the tip of the middle arm 8. The lower arms 11 of the crankshaft 10 made of metal rods are passed through the two front and rear claw plates 3b and 3c provided on the base plate 1 between the claw plates 3b and 3c and the wall plate 2, respectively.
The end is crushed to serve as a stop, and the lower arm 11
The middle arm 12 is bent into an L-shape, and the front arm 1 extends from the tip thereof and is bent in the opposite direction to the lower arm 11.
3 is formed. Forearm 13 located in front and back
is a presser member 1 consisting of a frame body with a downward U-shaped cross section.
The front arm 9 of the spring 7 also passes through the side wall plates 14a, 14b of the holding member 14 in a direction perpendicular to the longitudinal direction thereof.
It is rotatably attached to 4b. 15
is an engagement hole that engages with a locking piece 16 provided at the free end of the handle 6 when the handle 6 is laid down to maintain the pressure contact state of the holding member 14 against the base plate 1; In order to maintain a horizontal state in the locked state, the engaging hole 15 side is pre-distorted downward relative to the other surfaces, that is, a distorted portion 17 is provided in advance as shown by the imaginary line in FIG. be. B indicates a cover plate to which the base plate 1 is fixed, and the cover plate B has a spine b continuously provided between the front cover and the back cover a through a fold line.

When the present paper clip A is attached to the cover plate B, the handle 6 is rotated against the spring 7 to engage the locking piece 16 in the engagement hole 15. Then, the base plate 1 becomes distorted part 17 provided in advance.
is erased and returns to the horizontal state, and in this state it is fixed to the inner surface of the cover board B with rivets 18.

Effects of the invention As described above, according to the present application, the base plate maintains a horizontal state when the handle is locked to the base plate, so it is possible to easily attach the cover plate to the cover plate, and it is also possible to It has the advantage that there is no risk of reducing the amount of paper to be stored, and it looks good when stored.
