Description

[Detailed Description of the Invention] The present invention relates to a totalizer used in a bicycle distance meter, etc., and particularly relates to an improvement in the positioning pivot of a plurality of number wheels on a rotating shaft.

Conventionally, this type of totalizer has two frame plates 1 on the left and right, as shown in Figure 2.
, 2, the number wheels 3A, 3B... have a rotating shaft 5 on which the gear 4 is loosely fitted, and these number wheels 3A, 3B...
3B...The gear 4 is biased in one direction by the spring 6 so that there is no play in the axial direction of the number wheel and the gear, but in order to assemble this conventional example, From one end of 5 to the left side frame plate 1 and the coil spring 6
, number wheel 3A.

3B..., the gear 4, and the right side frame plate 2 must be inserted in sequence, and the coil spring 6 must be inserted in a pre-compressed state, making the assembly process complicated. there were.

In order to solve this problem, a locking groove T is bored in the rotating shaft 7 as shown in FIG. A member 12 consisting of a U-shaped grip part 9 and a spring part 11 which is continuous with one yoke of the U-shaped grip part 9 and has a long hole 10 in the center and is curved in a U-shape.
is attached to the left side frame plate 1 so as to hold the U-shaped grip portion 9, and the number wheels 3A, 3B, . . . and the gear 4 are urged in one direction by the spring portion 11. , a structure in which there is no play in the axial direction of the gear has been proposed, but this requires a step of drilling a locking groove 7' in the rotating shaft 7, and furthermore, the locking member 12 itself is It has a disadvantage that it has a complicated structure, requires many bending steps in the manufacturing process, and is difficult to manufacture.

This proposal was made in view of these points, and will be explained below based on the embodiment shown in the drawings.
, 2' U-shaped frame body, 14A.

14B... is a number wheel, 4' is a gear, 15 is these number wheels 14A, 14B... and gear 4'
Rotating shafts 16A, 16B, which are inserted through the frame plates 1' and 2' and pivotally supported between the left and right frame plates 1' and 2', correspond to the number wheel 14A.
, 14B... pinion gear for shifting, 17
is a pinion pivot shaft in which these pinion gears 16A, 16B, . . . are loosely supported between the left and right frame plates 1'2.

Reference numeral 18 denotes the plurality of number wheels 14A inserted between the left frame plate 1' and the highest digit number wheel 14A.

14B --- and gear-4' to the right frame plate 2'
This spring material 18 is a spring material that elastically biases the elastic plate in a curved shape, and a long hole 19 having a width Y narrower than the diameter X of the rotating shaft 15 is bored inward from the end. A locking groove 16 having an inner diameter 2 substantially the same as the diameter X of the rotating shaft 15 is bored in the center of the elongated hole 19.

Then, a plurality of number wheels 14A, 14B, ... and a gear 4' are inserted into the rotating shaft 15, and the left and right frame plates 1',
2', the spring material 18 is attached to the rotating shaft 15.
is inserted between the left frame plate 1' and the number wheel 14A of the highest digit through the elongated hole 19, and the rotation shaft 1 is inserted into the locking groove 16 of the spring material 18.
5, the center portion of this spring material 18 presses the number wheel 14A of the highest digit, and both ends of the spring material 18 press the left frame plate 1'.

The totalizer of the present invention fails as described above. In particular, a plurality of number wheels are arranged between the left and right frame plates by being inserted through a rotating shaft pivotally supported by the frame plates, and the outermost number wheel and the A spring member is inserted between the frame plate and one of the frame plates to press the number wheel, and the spring member curves the elastic plate and extends inwardly from the end to a width narrower than the diameter of the rotating shaft. The invention is characterized in that a long hole is bored in the center of the long hole, and a locking groove having an inner diameter substantially the same as the diameter of the rotating shaft and locking the rotating shaft is formed in the center of the long hole. The spring material can be constructed by simply bending an elastic plate and drilling a long hole and a groove for locking, and there is no need for a locking member with a complicated structure as in the past. This allows the ease of assembly work to be measured.

Furthermore, according to the present invention, there is no need to add side processing to the rotating shaft through which the number wheel is inserted, and the spring material is simply fitted onto the rotating shaft after the number wheel is placed between the left and right frame plates. Since it can be assembled with simple work, the manufacturing process can be streamlined and it can contribute to reducing manufacturing costs.
