Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a rotating member that can be manufactured at low cost and is easy to assemble.

Generally, in a motion transmission mechanism that changes the direction of motion and transmits it to another horizontal groove, a shaft with a circular cross section is often used as a rotating member.

Figures 1a and 2 are a front view, a side view, and an exploded perspective view showing an example of a collapsed support structure for a rotary member of this type in the past. A pair of bent parts IA and I that are opposite to each other by being bent in a U-shape.
A supporting member integrally having the bent portions IA and IB.
Holes 2.3 with different inner diameters are coaxially drilled in each of the holes 2.3.

Reference numeral 4 denotes a rotating member which is rotatably inserted into the holes 2 and 3 and prevented from coming off by a retaining ring 10. For example, two notches 5 and 6 are formed in the middle part of the outer peripheral surface of the rotating member 4. ,
A plate-shaped bracket 7 is attached to each of these notches 5 and 6.
．． 8 are fixed by set screws 9, respectively.

Furthermore, notches 11 are provided at both ends of the rotating member 4. 12
is formed.

Note that the rotation of the rotating member 4 is converted into a swinging motion of the bracket 7.8, which is transmitted to other mechanisms.

By the way, since the rotating member 4 is made of a round bar as shown in the figure, when installing the bracket 7.8, the additional part is cut with a milling cutter to make it flat, a pilot hole is drilled, and then a tap is made. It is necessary to form a hinge 1JL13.

Therefore, a large amount of manufacturing man-hours is required, which causes a significant increase in manufacturing costs.

Furthermore, if the tolerances are made stricter in order to reduce rattling, there is a problem in that the manufacturing cost becomes even higher.

The present invention was developed in view of the above-mentioned points, and has an extremely simple structure in which a plate-shaped rotating member and a pair of bearing members are used instead of the round bar 9, thereby significantly reducing manufacturing costs. To provide a support structure for a rotating member that is easy to measure and assemble.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

3a and 3b are a plan view and a right side view showing an embodiment of a support structure for a rotating member according to the present invention, and FIG. 4 is an exploded perspective view of the same support structure.

In these figures, reference numeral 20 denotes a supporting member that is formed into a substantially U-shape and integrally has a pair of opposing bent portions 21A and 21B, and each bent portion 21A and 21B is provided with a hole 22. .23 is drilled coaxially.

In this case, at least one of the JL holes 23, for example, is opened at the upper edge of the bent portion 21B by a notch groove 24.

Reference numerals 25 and 26 denote a pair of bearing members rotatably supported in the holes 22 and 23, respectively.Since these bearing members are formed identically, only one of the bearing members 26 will be explained. a small diameter portion 27 inserted into the small diameter portion 27; and a bent portion 21 connected to one end surface of the small diameter portion 27.
A large-diameter flange 28 that is brought into close contact with the inner surface of B, a plate-shaped fixing lip 29 that is provided approximately at the center of this large-diameter flange 28 in a direction protruding toward the other bearing member 25; It is composed of a small diameter part 27 button and a grooved hole 30 passing through approximately the center of the large diameter collar part 28.

The groove 31 of the hole 30 is composed of two grooves having the same groove width and formed at positions separated by 180 degrees.

, 1 A long hole 32 is formed in the fixing lip 29 .

Reference numeral 33 denotes a rotating member made of a plate and disposed on the support member 2.0 via the pair of bearing members 25 and 26, and is formed to be longer than the distance between the pair of bent portions 21A and 21B. 1. A pair of operating rods 34.
35, and step-shaped stops 36, 37 formed at the outer sides of the operating rods 34 and 35, respectively, by making the widths of both ends smaller than the central part.

One of the pair of operating rods 34 and 35 is provided to protrude above the rotating member 33, and the other operating rod 35 is provided to protrude in front of the rotating member 33, so that they are mutually connected. About 9
Extends to the egg with a 0 degree difference.

On the other hand, a stopper piece 38 bent in the same direction as the operating rod 35 is integrally provided at an intermediate portion of the lower edge of the rotating member 330.

A screw hole 39 is formed in the right end portion of the rotating member 33 in correspondence with the elongated hole 32 formed in the fixing rib 29 of the twenty-sixth bearing portion.

When attaching the rotating member 33 to the support member 20, first, both ends of the rotating member 330 are aligned with the grooves 31 of each bearing member 25, 26 and inserted into the holes 30, respectively.

At this time, the upper and lower edges a and b of both ends of the rotating member 33 are fitted into the groove 31, and rotation of the rotating member 33 is prevented.

Next, the small diameter portion 2T of the bearing member 25 is inserted into the hole 22 of the bent portion 21A, and the large diameter collar portion 28 is brought into close contact with the bent portion 21A, and the right end of the rotating member 33 is inserted as shown in FIG. 21B into the hole 23 through the cutout groove 24 of the bent portion 21B.

In this state, by pressing the button and shifting the rotary member 33 in the direction of the bent portion 21A, the stopper 36 and the left end of the stopper piece 38 are brought into contact with the bearing member 25.
prevents axial movement of the

Then, shift the other bearing member 26 in the direction of arrow A in FIG. The rotating member 3 is fixed to the rib 29.
Complete the addition of 3.

As a result, the rotating member 33 is rotated together with the pair of bearing members 25,26.

It goes without saying that the left end portion of the rotating member 33 may be fixed to the fixing lip 29 of the bearing member 25 by screwing.

Figures 6 to 8 show an example in which the support structure for the rotating member having the above configuration is applied to a public telephone. Figure 6 is an external perspective view of the public telephone, and Figures 7 and 8 are The figure shows the inside of the telephone when the handset is removed from the banger arm and when it is hung.

In these figures, 50 is a telephone body consisting of a box-shaped housing 51 with an open front, and a front door 52 that covers the front opening of this housing 51, with a handset and receiver on the left side. 53 is hooked on the banger arm 54.

Inside the housing 51, a support structure for a rotating member shown in FIGS. 3 to 5 is arranged substantially horizontally with its support member 20 fixed to the inner wall surface of the casing 21. .

At the left end of the rotary member 33 rotatably supported by the support member 20 via a pair of bearing members 25 and 26, a transmission lever 55 is attached to the banger arm 54 (shirt) 54aK. A transmission member 56 to which the rotation of the negative arm 54 is transmitted is fixed.

Therefore, when the arm 54 rotates due to shoulder detachment of the transmitter/receiver 53, this rotation is transmitted to the rotation member 33 via the transmission lever 55 and the transmission member 56, thereby causing the rotation member 33 to rotate. Rotated.

This rotating member 33 has one end connected to one operating rod 34.
A spring 57 whose other end is fixed to the inner wall of the casing 51 provides a habit of always rotating in the return direction.

An upper end portion of a coin sorting device 58, indicated by a chain line, is fixedly held at an appropriate location on the support member 20.

A flapper opening/closing rod 60 attached to the flapper 59 of the coin sorting device 58 is engaged with the other operating rod 35 of the rotating member 33.

In the communication state shown in FIG. 7, that is, in the state in which the handset 53 is removed from the hanger arm 54,
is in a raised position due to the force of the spring 57, and the flapper 59 is closed.

Therefore, when a user inserts a coin into the coin slot 61 provided in the front door 52 and the coin passes through the coin sorting device 58 and is classified as a genuine coin, a call is made according to the denomination. It can be carried out.

Next, after the call ends, the handset 53 is hung on the hanger arm 54 as shown in FIG. 8, and the hanger arm 54 rotates downward due to the weight of the handset 53, rotating the transmission lever 55 toward the back of the drawing. .

Since the rotation of the transmission lever 55 is transmitted to the transmission member 56, the rotation member 33 rotates in the direction of the arrow in FIG. 8 against the spring 57.

Therefore, the operating rod 35 pushes down the flapper opening/closing rod 60 to open the flapper 59.

Therefore, in this state, the coins inserted into the coin slot 61 are returned to the return slot 62 through the return path, so that the state in which calls are not possible is maintained.

Thus, according to the support structure for the rotating member having the above configuration, since the rotating member 33 made of a plate is used, the operating rods 34 and 35 can be integrally formed by press working or the like, instead of the conventional round shape. It is much easier to manufacture than a rotary member made of a rod, and manufacturing costs can be significantly reduced.

Further, the tolerances can be sufficiently handled with general (ordinary) tolerances, and furthermore, it can be easily assembled.

Note that the above embodiment is based on the arm 54 of a public telephone.
Although the case has been described in which the present invention is applied to a rotating member that controls the opening and closing of the flapper 59 in conjunction with the Of course, it can be implemented.

As explained above, in the support structure for a rotating member according to the present invention, the rotating member made of a plate is held by a pair of bearing members rotatably attached to the supporting member, so manufacturing of the rotating member is easy. This does not require any milling or the like, so the operating rod can be easily attached, which not only greatly reduces manufacturing costs, but also makes it suitable for mass production.

In addition, it does not require high processing precision and is easy to assemble, so its practical effects are very impressive.
