Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a pointer assembly for an instrument, to which a balancer for balancing the weight of the pointer is attached.

[0002]

[Prior Art]

 4 and 5 show perspective views and cross-sectional views of a conventional example of a pointer assembly for an instrument. As shown in FIG. 4, the pointer assembly for the instrument is in a state in which the pointer cap 2 is fitted from above the pointer 1, and the inside thereof is provided in the pointer 1 as shown in FIG. The pointer shaft 2b of the pointer cap 2 is inserted into the hole 1a, and the side surface of the pointer 1 is held by the side surface 2a of the pointer cap 2. Further, a pin 4 is provided on the upper surface of the finger 1, and a balancer 3 is attached to the pin 4. The balancer 3 is made of brass or the like having a specific gravity higher than that of the pointer 1, and balances the pointer 1 by adjusting the unbalance before and after the weight of the pointer 1 with respect to the needle shaft 2b.

[0003]

[Problems to be solved by the device]

 However, in general, the pointers and other components have variations in weight, and therefore the thickness of the balancer 3 and the material of the balancer 3 must be changed in order to balance them, which makes the adjustment complicated. There is. In addition, even if it is found that the balance is not right after it has been assembled, it cannot be adjusted and it is forced to be discarded, which is a factor of cost increase.

It is an object of the present invention to provide a gauge pointer assembly that allows adjustment of the weight balance of the pointer even after assembly.

[Means for Solving the Problems]

 The present invention is provided with a pointer, a pointer cap arranged below the pointer and fitted with the pointer, and a balancer arranged inside the pointer cap to balance the weight of the pointer with respect to the pointer shaft. In the pointer assembly for instruments, wavy projections are provided on both inner sides of the pointer cap, long holes are formed on the bottom surface, and engagement projections are provided on both side surfaces of the balancer. An operation protrusion that is inserted into the hole is provided, and the operation protrusion is operated from the outside of the elongated hole on the bottom surface to slide the balancer in the radial direction of the pointer shaft so that the weight balance of the pointer can be adjusted. Is characterized by.

[0005]

[Action]

 Based on the above configuration, when the engaging protrusions on the side surface of the balancer are engaged with the wavy protrusions on the inner side surface of the pointer cap, the operation protrusion on the bottom surface of the balancer is exactly the elongated hole provided on the bottom surface inside the pointer cap. The balancer is inserted and locked in the pointer cap. Then, after fitting the pointer to the pointer cap from above, move the operation protrusion of the balancer protruding downward from the long hole on the bottom surface of the pointer cap along the long hole, Slide the balancer engaged on the side face to adjust the weight balance of the pointer centering on the pointer shaft of the pointer cap.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of an instrument pointer assembly according to an embodiment of the present invention. As shown in the drawing, the instrument pointer assembly is composed of a pointer 11, a balancer 13, a pointer cap 12, and the like. The pointer 11 is made of resin, and a rectangular protrusion 11a is formed on the lower surface side thereof. And two pins 11b are provided. Further, the finger cap 12 has a substantially circular center portion 12 'and a square side portion 12 ", and the center portion 12' has a square hole 12c and two circular holes 12d. In addition to being provided, a pointer shaft 12b is integrally formed on the lower side of the central portion 12 '. The square hole 12c and the circular hole 12d are formed by the square protrusions 11a and 2 of the pointer 11. This is for fitting with the pin 11b of the book.

The side portion 12 ″ of the pointer cap 12 is box-shaped, the inner side surfaces thereof are continuous with wavy projections, and the bottom surface is provided with a long hole 12 e extending in the direction of the pointer shaft 2 b. The pointer cap 12 is also made of resin.On the other hand, the balancer 13 is made of metal such as brass and has engaging projections 13a on both side surfaces thereof, and a lower surface thereof. An operation protrusion 13b is provided.

Then, when the engaging projection 13 a of the balancer 13 is engaged with the side surface having the wavy projection 12 f inside the pointer cap 12, the operating projection 13 b of the balancer 13 is inserted into the long hole 12 e of the finger cap 12. It will be in a state where it is in a state where it protrudes to the outside. In this state, when the pointer 11 is fitted from the upper side of the pointer cap 12, the assembly of the meter pointer assembly shown in the perspective view of FIG. 2A is completed. Next, in order to balance the weight of the pointer 11 with respect to the pointer shaft 12b, as shown in the bottom view of FIG. 2B or the sectional view of FIG. The protruding operation protrusion 13a of the balancer 13 is moved forward and backward in the direction of the pointer shaft 12b as indicated by arrow A.

As shown in the enlarged view of FIG. 3A, the wavy protrusion 12 f inside the pointer cap 12 has a continuous gentle wave shape, while the engaging protrusion 13 a of the balancer 13 is also half. Since the concavo-convex portions are fitted to each other due to the circular shape, the pointer cap 12 is made of resin and is elastic, so the balancer 13 can slide inside as the operating projection 13b is operated. You can However, the balancer 13 does not move from the set position unless it is operated from the outside.

The wavy projection 12f inside the pointer cap 12 may be formed in a continuous triangular wavy shape as shown in FIG. 3B. In this case, the engagement projection 13a of the balancer 13 has a similar shape. To do.

[0012]

[Effect of the device]

 As explained above, according to the present invention, it is easy to balance the weight of the pointer during assembly, and the balance of the pointer can be corrected after assembly, so there is no need to dispose of the pointer due to poor balance, and the cost is reduced. Can be reduced.

Then, when the engaging projection 13 a of the balancer 13 is engaged with the side surface having the wavy projection 12 f inside the pointer cap 12, the operating projection 13 b of the balancer 13 is inserted into the long hole 12 e of the finger cap 12. It will be in a state where it is in a state where it protrudes to the outside. In this state, when the pointer 11 is fitted from the upper side of the pointer cap 12, the assembly of the meter pointer assembly shown in the perspective view of FIG. 2A is completed. Next, in order to balance the weight of the pointer 11 with respect to the pointer shaft 12b, as shown in the bottom view of FIG. 2B or the sectional view of FIG. The operation projection 13b of the balancer 13 protruding from the front is moved forward and backward in the direction of the pointer shaft 12b as indicated by arrow A.
