Description

[Detailed description of the invention] The present invention mainly relates to the improvement of an indexing device used in a telephone number quick checker, etc., and the illustrated embodiment has a base plate 3 with a top plate 2 stretched over the top surface of a dish-shaped bottom plate 1. A lid body 4 having an inverted dish shape is rotatably supported on the rear end of the lid body 4 through a shaft 5 so as to be freely openable and closable. A large number of cards 7... are stacked and stapled on 6, 6', and a notch 7' is provided on the side edge of the card 7, which becomes wider as it goes downward. A strong torsion spring 8 with a small leg opening angle and a weak torsion spring 9 with a large leg opening angle are wound, and both legs of the strong torsion spring 8 are pressed against the top surface of the bottom plate 1 and the inner surface of the lid body 4, and are pressed against the lid body 4. The weak force torsion spring 9 provides elastic force in the opening direction from the start of the opening operation until the half-opening.
Similarly, the legs are in pressure contact with the upper surface of the bottom plate 1 and the inner surface of the lid 4, and apply a resilient force in the opening direction to the lid 4 from the start of the opening operation until the lid is fully opened.

Furthermore, a through hole 11 is provided at the front end of the top plate 2, and a tip hook portion 12 is formed at the front end of the lid 4 so as to penetrate through the through hole 11 into the lower surface of the top plate 2 when the lid 4 is closed. A hook-shaped projection 13 is provided, and the center point of a locking rod 14 is horizontally rotatably supported on the lower surface of the front end of the top plate 2 with a support shaft 15, and one end 14' of the locking rod 14 is Torsion spring 16 wound around the support shaft 15
By the action of the stopper part 17, the hook part 12 of the hook-shaped projection 13 protruding from the bottom surface of the top plate 2 is naturally engaged, and the locking rod 14 of the lid body 4 is A push button member 20 integrally having a truncated inverted conical portion 19 at its lower end is attached to a location corresponding to the other end portion 14'' so as to be movable up and down and non-removable.
When a pressing operation is applied to 0, the truncated inverted conical portion 19 pushes out the other end 14'' of the locking rod 14 to the side against the acting force of the torsion spring 16, and the one end 14 of the locking rod 14 is pushed out against the force of the torsion spring 16. A leaf spring member 21 is fixed to the upper surface of the bottom plate 1 to push up the truncated inverted conical part 19 and return the push button member 20.

Further, a guide hole 23 is provided in the lid body 4 parallel to the edge of the card 7 on the side where the notch 7' is provided, and a head portion 24 and an inverted T-shaped pillar portion 25 are formed in this guide groove hole 23. Insert the slide knob 22 from the outside to engage both jaws of the head 24 with the incisal edges on both sides of the guide groove hole 23, and make the lower half of the column 25 protrude below the guide hole 23. constitutes a U-shaped member 26 separately, and a square hole 29 having a diameter larger than the length of the lower horizontal portion 28 of the pillar portion 25 is opened in the upper horizontal portion 27 of this U-shaped member 26. A notch 30 whose opening is narrower than the lower horizontal part 28 of the column part 25 and wider than the vertical part 28' of the column part 25 is cut at the outer edge of the hole 29, and the vertical part 28 of the column part 25 is inserted into the notch 30. ′
The lower horizontal portion 28 of the columnar portion 25 is inserted into the square hole 29 and the U-shaped member 26 is moved laterally to fit together. ' are engaged with the lower surfaces of both ends of the cut edges of the notch 30, and at the upper horizontal part 27 of the U-shaped member 26, the column part 25 is fitted into the vertical part 32 of the U-shaped member 26 and the above-mentioned notch 30. A bi-fold leaf spring 33 having the same width as the space is attached by pushing it from the side, and a cut-out claw 34 is provided on the upper side of this bi-fold leaf spring 33. Raise claw 34
is locked to the incisal edge of the square hole 29 to make the bifold leaf spring 33 unremovable, and furthermore, a protrusion 35 is attached to the inner edge of the upper side of the bifold leaf spring 33 at the tip.
An arm-shaped bullet piece 36 is integrally provided, and a number of concave portions 37 are arranged in a row on the lower surface of one incisal edge of the guide groove hole 23, and the protrusion of the bullet piece 36 is provided in the concave portions 37. 35 can be selectively engaged, and the lower horizontal portion 27' of the U-shaped member 26 can be freely engaged with the notched side edge of the card 7.

Since the present invention has the above-mentioned configuration, it goes without saying that the indexer can be attached to the lid body very simply and easily. At a location between the vertical part of the U-shaped member and the pillar part fitted in the above-mentioned notch, there is an arm-shaped bullet piece with the same spacing between the two parts and on one side edge of the upper side plate. , and a bi-fold leaf spring with a raised claw is fitted to the center of the upper side plate.
The cut-and-raised piece is locked to the cutting edge of the square hole, and the arm-shaped bullet piece is slidably joined to the lower surface of the cutting edge on one side of the guide groove hole, so that the bi-folded plate is formed. The spring is located on the horizontal part of the upper side of the U-shaped member, between the vertical part of the U-shaped member and the pillar part of the slide knob that fits into the above notch, and the pillar part moves to the square hole side and the slide knob is inserted. By locking the raised piece provided on the bi-fold leaf spring with the cutting edge of the square hole, the cut-and-raised piece provided on the bi-fold leaf spring can be prevented from separating from the U-shaped member. In addition, the arm-shaped elastic piece provided on the bifold leaf spring is slidably joined to the lower surface of the incisal edge on one side of the guide groove hole. This is to prevent unnecessary sliding of the index element and to ensure that the lower horizontal part of the U-shaped member is engaged with the edge of the notched side of the card. This has the effect of making the structure of the index firm and perfecting its function through such a complex operation.
