Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides an opening/closing member provided with a binding rod and a connecting mechanism for removably connecting the opening/closing member to the left and right edges of the mounting member. The present invention relates to a storage device configured such that the opening/closing member can be attached and detached by operating the connecting mechanism from either side.

0002

[Prior Art] Conventionally, a mounting member is provided with connecting shaft tubes at the front and rear positions of the left and right side edges of a rectangular board, and nail-shaped and tubular binding rods that can be inserted into each other are installed at the front and rear positions of the inner surface, respectively. It consists of a pair of hollow left and right opening/closing members each provided with a shaft tube that is planted and connected to the shaft tube along the lower edge, and a connecting mechanism disposed within each opening/closing member. The mechanism includes an operating plate that is slidable in the front and rear directions, a spring that always presses the operating plate in one direction, a pair of front and rear connecting rods that are locked to the operating plate, and a lock piece that locks the operating state of the operating plate. In the non-operating state, the front and rear connecting rods are in a connected state in which they protrude from the shaft cylinder of the opening/closing member into the shaft cylinder of the mounting member due to the biasing force of the spring, and from this state, either the left or right operation plate is connected. When the lever is slid by applying finger pressure against the spring, the connecting rod that is locked to the actuating plate escapes from the shaft cylinder of the mounting member, and the shaft cylinders are disconnected from each other, and this operating state is changed by the locking part. Double-sided opening/closing type binding that locks and the other opening/closing member rotates relative to the mounting member to release the connection, and one opening/closing member separates from the mounting member to enable the binding operation of paper, etc. For example, the fittings are
It is known in Japanese Patent No. 2-123979.

0003

However, according to the above-mentioned conventional structure, the opening/closing member can be uncoupled from either the left or right direction to load sheets, etc., which is convenient for use. Since the operating plate is provided on the opening/closing member side, when finger pressure is applied to the operating plate against the spring in order to separate the opening/closing member from the mounting member, the finger pressure will cause the opening/closing member to separate from the mounting member. This has the disadvantage that it acts in a direction that restricts the movement and impairs the operability of the opening/closing member.

0004

[Means for Solving the Problems] Therefore, in order to solve the above-mentioned disadvantages of the conventional method, the present invention provides a mounting member having shaft tubes on the left and right side edges, and a binding rod that can be inserted into each other protruding from the inner surface. and a pair of left and right opening/closing members each having a shaft cylinder connected to the shaft cylinder, and a connecting rod inserted into and retractably through the shaft cylinder of the mounting member, and the connecting rod is normally closed by an elastic biasing force. protrudes from the shaft tube of the mounting member and inserts it into the shaft tube of the corresponding opening/closing member to rotatably connect the shaft tubes, and when pressed against the elastic urging force, the connecting rod is attached. A pair of left and right connecting mechanisms disposed on the mounting member which sinks into the shaft cylinder of the member and disconnects from the shaft cylinder of the opening/closing member, and a disconnected state where the connecting rod sinks into the shaft cylinder of the mounting member. the mounting member corresponding to each of the connection mechanisms that is held and released when the holding state reaches a position where the shaft cylinder of the opening/closing member can be connected to the shaft cylinder of the mounting member to allow the protrusion of the connecting rod. The present invention proposes a binding device comprising a pair of left and right holding mechanisms arranged at the mounting member, and an operating section for operating the coupling mechanism arranged at the left and right positions of one end of the mounting member. be.

[0005] Preferably, in the above, the connecting mechanism is constituted by an operating rod that is slidably attached to the mounting member in the front-rear direction and is provided with a connecting rod, and the holding mechanism is configured such that the connecting rod is attached to the shaft of the mounting member. When retracted into the cylinder, the connecting rod is engaged with the mounting member at the connecting position of the shaft cylinder of the opening/closing member to maintain the retracted state, and in this state, the uncoupled opening/closing member reaches the connected position. The holding lever is composed of a holding lever having a claw piece at its free end that acts on the shaft cylinder provided on the opening/closing member to release the locking state with the mounting member, and the base of the holding lever is horizontally rotated around the operating rod. The sliding member is movably pivoted between the base of the holding lever and the mounting member, and at the same time the sliding member is elastically biased in the direction in which the connecting rod protrudes from the shaft cylinder of the mounting member. It is made up of a spring that constantly biases the claw piece to rotate in the direction of locking with the mounting member. Also, when one of the binding rods that can be inserted into each other is nail-shaped and the other is tubular, and a nail-shaped binding rod and a cylindrical binding rod are respectively protruded from a pair of opening/closing members. The left and right opening/closing members can be used in common.

[0006]

[Operation] In the non-operating state in which the pair of left and right opening/closing members stand up and face each other, the shaft cylinder of the mounting member and the shaft cylinder of the opening/closing member are rotatably connected by the connecting rod. From this inoperative state, when one of the left and right operation parts is pressed with a finger against the elastic biasing force, the corresponding one of the connecting mechanisms is activated, and the connecting rod disengages from the shaft cylinder of the opening/closing member, causing the shaft of the mounting member to move. Since it is recessed into the cylinder, one of the opening/closing members is released from the connected state, and the unconnected state of the connecting mechanism is maintained by the holding mechanism.

[0007] Therefore, in this state, the other opening/closing member connected to the mounting member rotates outward at the connected position, the binding rod stands up, and the pair of opening/closing members face each other vertically. Next, in the same way as in the past, the mutual insertion of the binding rods is released and one of the opening/closing members is removed to bind papers, etc.
After inserting the binding rods into each other again and binding paper, etc. into the binding rods, one of the unconnected opening/closing members is moved back to the original connecting position, and its shaft cylinder is moved to the position of the shaft cylinder of the mounting member. , the holding state by the holding mechanism is automatically released, and the connecting mechanism moves back due to the elastic urging force, and the connecting rod connects the shaft cylinder of the mounting member and the shaft cylinder of one opening/closing member. are connected again.

By caulking the substrate 1a and the cover 1b, a mounting member 1 having a required gap is formed between the substrate 1a and the cover 1b.

A pair of left and right opening/closing members 11 rotatably connected to the mounting member 1 engages the periphery of a metal inner plate 11a with an outer periphery holding portion 12 of a synthetic resin outer plate 11b. Nail-like binding rods 13 or tubular binding rods 14 may be implanted at both longitudinal ends of the inner plate 11b, but in this example, as shown in FIG. The case is shown in which nail-shaped binding rods 13 and tubular binding rods 14 are respectively implanted at both longitudinal ends of the inner plate 11b so that the left and right opening/closing members 11 can be used in common. At the lower edge of the configured inner plate 11a, there is a pair of front and rear shaft cylinders 15 connected to the shaft cylinder 2 of the mounting member, and when connecting the opening/closing member 11 to the mounting member 1 by curving inwardly, A pair of front and rear guide pieces 16 are provided which fit into the outer circumferential surface of the shaft tube 2 of the mounting member 11 while slidingly contacting it to guide it into a connected state.

A pair of left and right connecting mechanisms 17 that rotatably connect the opening/closing member 11 to the mounting member 1 are located at the left and right halves in the widthwise direction of the gap formed between the substrate 1a and the cover 1b. The configuration is such that a concave surface 18 is formed on a part of the upper surface in the longitudinal direction of an elongated synthetic resin piece, and notches 19 are provided at two locations in the longitudinal direction, and
A wide operation part 20 is provided at one end in the longitudinal direction, and an operation rod 22 having a guide shaft 21 slidably fitted to the shaft cylinder 2 located at one end of the mounting board 1 on the outer side thereof. , a pair of front and rear connecting rods 23 which are bent into an L-shape and whose bent ends are engaged with the notch 19, respectively, and a spring which always presses the operating rod 22 in one direction.

By fitting into the shaft tube 2 of the base plate 1a, it is arranged so as to be slidable in the front and rear directions on the substrate 1a.

The holding mechanism 26 that maintains the uncoupled state of the coupling mechanism 17 has a base supported on the concave surface 18 of the operating rod 22 via a shaft piece so as to be horizontally rotatable, and has an upper surface at the free end. It consists of a holding lever 29 which is inclined outward and has a protruding claw piece 28 having a locking step 27 at its base, and a spring which constantly biases this holding lever 29 to rotate outward. Now, the stopper 3 provided at the base of the holding lever 29

The claw piece 28 of the holding lever 29 mentioned above is pressed against the inner surface of the guide rib 8 provided on the cover 1b by the rotational urging force of the spring 31 when the mounting member 1 and the opening/closing member 11 are connected. When the operating rod 22 slides against the biasing force of the spring 31 and the connection between the mounting member 1 and the opening/closing member 11 is released, the guide rib 8 projects outward from the inner edge 8a of the guide rib 8. The locking step portion 27 locks on the inner edge 8a of the guide rib 8. Note that reference numeral 32 denotes a cutout portion provided at a corner position of one end in the longitudinal direction of the mounting member 1, and the operating portion 20 of the coupling mechanism 17 faces this position so as to be movable back and forth.

[0013] Therefore, the pair of left and right opening/closing members 11, 11
In the inactive state shown in Figure 1, where the two are standing up and facing each other,
As shown in the left half position of FIG. 3, when the operating rod 2 is elastically biased downward in the figure by the spring 31, the front and rear connecting rods 23 are connected to the axis of the opening/closing member 11 from the axis tube 2 of the mounting member 1. The mounting member 1 and the opening/closing member 11 are connected to each other by protruding into the cylinder 15, and the claw piece 28 of the holding lever 29 is connected to the spring 31.
The guide rib 8 is pressed into contact with the inner surface of the guide rib 8 due to the rotation urging force.

In order to separate one of the opening/closing members 11 from the mounting member 1 from this inoperative state, one of the operating portions 20 is pressed in the direction of the arrow against the spring 31, thereby causing the operating rod 22 to move upward in the figure. As shown in the right half position of FIG.
5 and immersed into the shaft cylinder 2 of the mounting member 1, the connection between these shaft cylinders 2 and 15 is released, and the holding lever that was in pressure contact with the inner surface of the guide rib 8 due to the sliding of the operating rod 22 29 claw pieces 28 protrude outward from the inner edge 8a of the guide rib 8, and the locking step 27 is engaged with the inner edge 8a, thereby changing the sliding state of the operating rod 22, that is, one of the coupling mechanisms. 17 unconnected states are maintained.

[0015] When one opening/closing member 11 is disconnected from the mounting member 1 in this way, the other opening/closing member 11, which is rotatably connected to the opening/closing member 1, rotates outward and the nail is removed. The shaped binding rod 13 and the tubular binding rod 14 stand up, and as shown in FIG.
As shown, the pair of left and right opening/closing members 11 are placed facing each other in the vertical direction.

Therefore, as in the conventional case, one opening/closing member 11 separated from the mounting member 1 is removed from the other opening/closing member 11, and the binding holes drilled in paper or the like are inserted into the binding rods 13 and 14, and then the opening/closing member 11 is removed again. After one opening/closing member 11 is connected to the other opening/closing member 11, when the other opening/closing member 11 is rotated upright with respect to the mounting member 1, the leading edge of the regulating piece 16 is aligned with the outer periphery of the shaft cylinder 2 of the corresponding mounting member 1. The curved inner surface of the guide piece 16 moves inward while slidingly contacting the surface, and the curved inner surface of the guide piece 16 fits into the outer circumferential surface of the shaft tube 2. As a result, one opening/closing member 11 is drawn inward, and the shaft tube 15 is moved inward. This corresponds to the position where the mounting member 1 is connected to the shaft cylinder 2. Then, the holding lever 2 with the shaft cylinder 15 of one opening/closing member 11 protruding from the side of the mounting member 1
The claw piece 28 is pressed inward against the spring 31 by coming into contact with the tip inclined surface of the claw piece 28 of No. When the lock is released, the operating rod 22 automatically moves back to the non-operating position due to the biasing force of the spring 31, the connecting rod 23 connects the shaft cylinders 2 and 15, and the pair of left and right opening/closing members 11 are in the upright state again. to face each other.
