Description

Device for automatic switching and stopping of card tracks. Addendum to patent 30362c9. The subject of the invention is a device for automatic reverberation and, stopping of route and terrain maps for Walkers, cyclists, motorists, aviators, and all types of travelers.

There are already devices for the independent operation of route maps become known in which, as in the present invention, the card tracks unwound from one roller and rolled onto a second roller and attached to the required Can be shut down.

In these known devices, however, it is necessary at To turn a roller by hand or mechanically by moving forwards or backwards advance by pressing the lever.

Here it is necessary that the person operating the apparatus is constant directs all their attention to the card reading lane to ensure the shutdown is accurate to be able to do this at the required moment.

The roll-up roller is namely in this known device, depending after it has rolled up a larger or smaller piece of the reading path and thus has a larger or smaller diameter, .das rolling up in effect shorter or longer time.

When using a moving car, bicycle, Cars or airplanes now require: that the driver has his full attention on the way and by setting a connection card not of his Driving observation is distracted.

To-. For this purpose, according to the invention, a map in fields divided, which are provided with numbers. The card reading lane is in as well divided into many fields in which the card sections are glued in the sequence of numbers or are imprinted.

All you have to do is press a button and continue the Route switches itself on automatically without further observation.

The device can easily be attached to any handlebar or steering wheel attached is round and rotatable on its own axis. So the driver can Always turn the device so that the route on the map is in the same direction how the real driveway runs.

In the drawing, the subject of the invention is on a reduced scale shown, namely Fig. i shows a map, which is provided with numbers in FIG Sections is divided. These sections are cut out and glued together in the sequence of numbers so that a band of cards results, as shown in Fig. 2.

Fig. 2 shows a card reading path with fields, divisions and continuous lines Numbers. Fig. 3 shows the drive of the reading path in a longitudinal section along the line A-B in Fig. 4. Fig. 4 shows the same drive with broken reading path and removed Support plate for the latter as well as two smaller reading lanes on both sides of the reading lane with the names in alphabetical order of those found throughout the map Cities and villages, on the left the names from A to M and on the right the names of N to Z.

Fig. 5 shows in detail the control of the switch-on after the Line E-F in Fig. 4.

Fig.6 shows the automatic. Inhibition of the drive in a somewhat enlarged manner Scale according to the line C-D in Fig.4.

Fig. 7 shows the course of the small reading lanes for the place names der- line G = H in Fig. 4.

As can be seen particularly from Fig. 4: the device consists made of two metal strips d, which are stiffened by two b.

In this frame, a drive wheel c is stored, which in a known manner in the direction of the arrow shown in Fig. 4. is set in rotation by a spring d, of which one end e with the wheel axle and the other end e 'with which is loosely seated on the axle. Drive wheel c is connected.

There is also a movable semicircular disc in the frame g2 installed, which can be controlled by the lever.g 'protruding at g-and at the ends each has a <small gear-1a and -h '.

Depending on the position: of the lever g1, the gear wheel h or h ' engages in the ring gear of the drive wheel c and thus enables the changeover to V, local or reverse rolling of the reading path.

The wheels k and engage for further drive transmission. h ' into the teeth of the gears z and i', which are designed as bevel gears upwards and set in rotation by the bevel gears and k ', shaft E and L'. These have gears in and at the other end. in: 'and set the gears of the axis through intermediate gears n and n'. the winding rolls o. and o '. in motion: Sä -will die- reading path. depending on the position of the control love gl @ wound up or down.

To keep the machinery running smoothly and smoothly. is a regulator a (built in (see Fig. 4 and 6),% velcher from the drive wheel c is driven by two transmission gears c 'and c' and an intermediate gear c3.

Used to hold the card track automatically at a certain point Now the following device by means of chopsticks attached to the card track or other Reinforcements p (Fig. 2 and 4), the web is divided into individual sections of the same. Divided length.

These rods are presented in a known manner (patent 3o3629) the locking device, which consists of the sheet metal strip q and (len angles of rotation q '.

Furthermore, in a known manner (patent 3o89o7) the dhxrch gives the scope the sliding = roller y divided length of a section of the reading path is the number of Revolutions of the sliding roller on; which are necessary to pass a section permit. When connected to a pinion, the sliding roller (read gear t (Fig. 6). Its circumference with the circumference of the sliding, val # ze r multiplies the length of a section of the reading path results.

How Alb. 4 and 6 show the gear t is on the inner side with connected to a smooth, smaller wheel t ', in the edge of which a round indentation t 'is let in. Next to the wheel t 'is a movable Schaltann .: v -änhabeni which: with a pin v 'and .by a.spring: v = against the wreath of the wheel t 'is pressed .. The switch arm. v is. continue @ .by- one.- He :. evil v3 connected to a brake pad u =; which on a wheel disc u 'of the regulator u rests loosely.

Fig: i can be seen; However, the individual sections must be demonstrated, occasionally also mixed up. However, according to the invention, this should not be made possible by continued turning or switching, but only by pressing a button once. Then without: j ede. further observation; the required section = automatically : Einstellerr.-This is 4n: in the following way - achieved: Assumed ;, es :. should a trip be made. which. by. all sections of the map: leads ;. urrd- if you take a :, point- in section io as the exit, then the path leads. from io natS-5; Difference-- 5- . - 5 "_ 6, _ +1 _ (' _`-.

The driver - # rird = set the section.ia at the start of the journey and: the road in the direction of the arrow. exit (Fig, i). At the end of the road. indicates - a = number on which, Ab @ sclülitt. the way continues by specifying the difference between: the: individual sections, and indeed: with a falling number with a minus sign and with an increasing number with a plus sign. Instead of the minus and plus signs, you can also use different colors for the digits.

As from the above: -. long: the assumed journey can be seen, in the classification according to Fig. i, the greatest difference is 5 plus or 5 minus. Plus or minus is set by lever g ". But it is necessary yet another device that does d'ß with a single press of a button a certain number of sections can be moved at the same time.

This is achieved in the following way: As A # bb.4 and 5 show, five buttons i, 2, 3, 4, 5 are attached to the device. A rod w, which is hinged at w'- and is held in its position by a weak spring w2, is attached under the switch buttons i to 5. The-rod-w: acts-as the radius of a circle- and when-pressing .avf button -5, as-lying closest to the center wl-of the imaginary -circle, with the end w, it becomes lower: lower than when you press button 4; and with- button 4 again deeper than when you press button- 3.

On the bar-u, at w3 there is one standing down, up to the-release lever ° v4-reaching rod attached, which is provided with outwardly projecting noses v4- is.

There .the buttons by small levers with the metal strips q- of the release & lever v4 are connected, when a button is pressed it will trigger at the same time of the drive and: a shifting rod w @ in front. reached the release lever v4, and all the more deeply; the higher: the .. number of the push button is: During the Button jumps back into its original position after being pressed, the rod-.w4 - through-.den @ Wi, derstan @ d: des. Lever v4 held and must turn especially released.

For this purpose, t is a small one on the counting wheel. Lever.-0 attached; which- by a. Spring t4 and pin tr, held in place,: is: At = every rotation. : of the counting wheel :. t becomes: therein the rod w4 by a nose distance lifted until -then after the length of the release lever determined by the button .v4 again from: the rod w4 is freed. and-the pin vt shut down the drive again can.

Introductory remarks would suffice if the reading path was only to one side rolled.

Since j edßch, d: ie read track is forward and backward, must move to a: to achieve plus or minus the Absehnittslmmmern so - continued to serve the following means; As can be seen from Fig. 4, the slide roller r carries two pinions r: 'and r2, which are separated from each other by twice the wheel thickness, on its axis which is extended at the right end.

In addition to the pinion rI- a special Ritzet s is attached, which is rotated by Ritzet yl. Ritzet r 'and Ritzet s move each gear' t and t3, which wheels are designed as counting wheels, as their circumference the circumference of the: slide roller r multiplied, the length of the reading path results. As a result of the special pinion s causes the wheels t and t3 to always oppose each other move towards each other, and the arrangement shows that the counting wheel t, as the plus wheel and: the wheel t3 is to be regarded as the minus wheel.

Is the position of the lever ts such that it lifts the rod w4 and the Reading path rolls up from the bottom (plus position), so it will the Turn counting wheel t from left to right. The same thing works in the opposite position Lever t6 on wheel t1 and the reading track rolls from top to bottom.

In order to prevent that the lever t 'on your wheel, whichever is turns from right to left, pushing the noses of the rod u, 'downwards, is that Provision has been made that the lever t3 can give way during this rotation by he finds no resistance on this side.

As can be seen from Fig. 4, there are the Reading strips for the cities and villages on the map are attached.

The same are moved forward if you turn the screw z to the right turns. If the strips are to be moved backwards, the screw must be turned to the left Turn and at the same time also push inwards, so that the bevel gear of the reverse gear seized and .the forward gear is switched off.
