Description

[Detailed description of the invention] Distance gl measuring device for areas with reset equipment A or its similar This invention is based on the patented invention. Scope 1 relates to the range measuring device for ground UA described in item 1 or its analogues.

When it comes to such distance measuring devices or curve meters, the size of the device should be kept as small as possible. It is small and thin enough that it does not take up space in the Y4 band of the measuring device and can fit in your clothes pocket, or The pocket part of the glove should be conveniently sized so that it can be placed in the storage compartment of the car. Efforts are being made to In addition, this kind of 112 figure I14 foot device can also be used as a gift. Therefore, it must be produced as cheaply as possible, and be as easy to operate as possible. It is required that the product is capable of being used and has a high frequency of operation.

〈After use, the rewinding gear must be turned to the zero position, and the Watching the meter carefully for a while is a painstaking task; [1 nali General known map measuring instruments equipped with a set device are equipped with a reset device. , there is a gear inside the case, which is inserted around its outer circumference through a corresponding opening in the case. The device extends radially outwards into a small portion of the gear to rotate the gear. Therefore, relatively fast rotation is possible and supported due to the instructions of the measuring instrument. The indicator needle can be seen until the hand returns to the initial position or zero, and from there the next distance g! Measurement operations can now begin. However, the device may The disadvantage is that the indicator needle easily oscillates beyond zero, and this is caused by deceleration. This is due to the inertia of the transmission gears, which are subject to significant acceleration during the reset operation. Therefore, during the reset operation, it is necessary to watch the RA needle precisely and to keep an eye on the outside of the case. It is necessary to carefully turn the gear on the reset device.

This invention improves the two problems of distance measuring devices as claimed in claim 1. This makes resetting the indicator needle of the measuring instrument easier and more reliable. , ms structure to reduce manufacturing costs.

First, by adopting the structure set forth in claim 1, the above-mentioned opening can be achieved. As stated in the characteristic explanation part of Request 1, this problem can be solved.

Such resent action is itself known as a cylinder type instrument. However, instructions according to the present invention. How easy, fast and above all automatic It works with great accuracy and is highly recommended. The operating pin is pushed in and the indicator axis of the map measuring device As a result, the G-speed gear rotates rapidly, and the G-speed gear moves like an acceleration gear. All the floats at the site, especially the rotating wheels of the measuring instruments, are accelerated, and the rotating wheels are placed on a map or similar When rotating on top of an object, it rotates quite quickly and at the same speed as g. It is. In addition, this design of map measuring instrument can be used with existing general map measuring instruments. It can be done cheaper than a container. This is a quick-acting device that was not necessary for the existing resent operation. This is to omit the location.

Preferred design embodiments of the invention are set out in the subclaims.

The invention is illustrated by way of example in the figures.

FIG. 1 is a plan view of the distance M measuring device.

Figure 2 is the same plane of the distance measuring device after removing the upper half of the case in Figure 1. is a diagram, Figure 3 shows the distance #II4 ruler viewed from the direction of arrow ■ in Figure 1, with some parts A cross-sectional view taken along the line m-m in Fig. 2, and Fig. 4 are shown by the arrow ■ in Fig. 2. FIG. 3 is a side view of the slider material of the distance measurement device as seen from the direction;

The illustrated distance gi measuring device or its analog is located between the lower half l and the upper half 2 of the Uzing. , both of which have round indicator housings 3 and 4 on the outside, respectively. ．． The ordinary indicator fIII+7 is mounted on both walls 5 and 6 of the indicator housings 3 and 4. and protrudes axially into the indicator housings 3 and 4, Place each indicator needle 8 and 9 in each of groups 3 and 4.

A dial device 10 mounted on both walls 5 and 6 is suitable for such measuring instruments. It has been attached since then, and although I will not show it in detail here, there are , there are different concentric arcs and correspondingly different measuring scales to indicate the measured distance. It is. In addition, the tangential line 11 for the two indicator housings 3 and 4 The small rotating wheel 12 mounted above is the housing on the left in Figures 1 and 2. located between the two housing halves l and 2 at the end of the Placed on the long line, distance g! When using a measuring device, use a map or similar object. , eight wheels 12 rotated along the route to measure the multilayer reduction loading 1 3. Via the largest gear 14 fixed to the indicator shaft 7, the indicator 87 is driven. Concatenated. the 'g speed transmission device provided in the gear(s) of the housing; Since the position is well known in the past, details and 2 here also refer to m-long handles 1 & and 2a. , the handle is longitudinally separated within the plane in which the housing separates. Three handle parts 1a consisting of two half-shells and a lower half l of the housing and one handle part z & for the purpose of joining the housing upper half 2 together with the latter and said housing. 1 has several small holes 15 drilled along its edge to fit A pin or protrusion (not shown) is attached to the upper half 2 of the housing, and the The upper housing halves 2 now match.

The distance accumulator with the above-mentioned structure is known, and is therefore not a subject of the present invention. stomach.

As can be seen from FIGS. 2 and 3, the cam member 16 is connected to the gear 14 of the transmission unit 13. It is fixed on the indicator shaft 7 adjacent to and fixedly attached to the gear 14 as well. That power The outer circumferential curve 17 of the beam material 16 is mathematically precise with its point on the @ line of the indicated axis. It is a part of Archimedes' spiral curve. In this connection, gear 14, cam The material 16 and the indicator shaft 7 can be formed by joining together as an integral molding made of polyamide material. It would be advantageous.

The slider material 18 is placed under the housing on the side of the gear 14 that is separated from the ring 12. On the wall 5 of the half 1, along the direction transverse to the tangential direction 11, the surface of the cam member 16 is located within range. In the transverse direction, the slider material 18 It protrudes to a range in the radial direction 19 of the indicator shaft 7 parallel to the tangential direction 11. Slider The material 18 is installed in the space between the radial line 19 and the tangential line 11. cam In the radial line 19 towards the material 16, the slider material 18 is aligned with the reset bin 2. 0 and can be interlocked with the cam member 16 in the manner described below. . The slider member 18 has a tangential line on the other side that protrudes in front of the lower handle part 1&. 11, in the axial direction of the long handles 1a and 2a. There is also a hook 281 on the tangential fill extending in the direction, and the hook 28 is the fourth As shown in the figure. The hook 28 protrudes toward the upper half 2 of the housing and is attached to the operating pin. At one end of the hook portion 28a, the hook portion 28a is oriented in the direction of actuation of the ring 24. The tension spring 21 is caught, and the other side of the spring is the half-shell part of the long handle La. It is connected to a hollow pin portion 22 that projects into the hole in the chamber. In addition, the hollow The hollow part of the pin forms a hole 15.

Furthermore, the slider material 18 is arranged between the tension spring 21 and the reset pin 20. An operating pin 24 projects outwardly through a suitable opening 23 in the lower housing half 1. Therefore, when the operating pin 24 is moved in the direction of pushing into the housings 1 and 2, , the stay material 18 is attached to a tension sprue installed between the hollow pin 22 and the hook 28. It is urged against the force of the ring, and the movement is transmitted to the reset bin 2o. In addition , the slider member 18 is disposed between the outer circumference of the cam member 16 and the tangential direction 11. It has a protrusion 25 that protrudes between 1 and 2, and this disaster generating part 25 1 has a long groove or slot 26 parallel to the slot 26, and the slot Z= , the guide pin 27 fixed to the wall 5 is sandwiched between the guide pins 27, so as mentioned above, this step Even if the rider material 18 is pushed and moved, it is guided without being bent or dented.

The final connecting wall between the guide pin 27 and the bottom wall 6 of the lower half if of the housing (not shown) When the operation pin 24 is pushed into the housing, the slider material 18 The reset bin 2o acts as a reliable guide for the initial or It is displaced radially toward the cam member 16 until it reaches the zero position. among them , the reset bin 20 is a concavity formed by the Archimedean circumferential curve 17. 16a, thereby retaining the cam member 16 in position and the pointer 8 and 9 are also in their zero position.

As mentioned above, when the reset bin operates on the external curve of the cam part, the cam part is It is a well-known fact that the lock will reliably turn to the zero position, so this No more detailed explanation is necessary; however, in this case, guidelines 8 and 9 The return movement centering on the gears of the reduction gear 13 and, ultimately, the wheels 12 simultaneously This is possible only when MD is used for reverse rotation. However, in actual experiments For guidelines 8 and 9.

Despite the acceleration effect caused by the reset operation related to As the device 13 accelerates and decelerates considerably, the rotational movement of the indicator shaft 7 is rotated. This is obtained by converting to a fairly fast counter-rotating motion of 12.

Regarding the device of the slider part 18, although it has been mentioned before and is also depicted in Figure 1, It is possible to install it in the housing 1.2 on the tangential line 1 in front of the handles 1a and 2a. It is. Its operating pin is located outside the housing 1.2 at a position crossing the tangential line 11. The protruding and resetting pin is inwardly directed toward the cam member 16 in the direction of the operating pin. connected directly to. In that case, instead of the already mentioned tension spring 21, a compression spring 21 is used. It is also possible to use springs. This spring is located in the housing L,2 The other side of the operation bottle and the slider member are combined, and 1, for example, the outside of the cam member 16 is It is also possible to position it horizontally on the circumferential surface. 8 is arranged in the embodiment described and illustrated.

Although within Applicant's current knowledge, polyamides are , is considered to be particularly suitable as a glass material for integrally manufacturing the adjacent gear 14. , a plastic material with similar properties may be used.Normally, the indicator shaft 7 is made of metal. , also metal gear 14. It is made of metal cam material 16, but they are manufactured in one piece. It may also be made of plastic material. Also, these structural parts , integrally made of plastic material is also within the protection scope of the present invention. Cam material No. 16 does not fall outside the scope of protection for non-invention, and the above-mentioned desirable features are If available, then instead of the mathematically exact Archimedean spies, roughly It is sufficient if the outer peripheral surface has a similar curve.
