Abstract

Vynález rieši zariadenie na stabilizáciu rúčky kružidla, ktoré má lamelovú kulisu posuvné uložená medzi rozšířenými kíbovými koncami ramien kružidla a má v kulise vytvořené dva, oproti sebe, horizontálně vodiace výřezy, medzi ktorými prechádza os kíbu kružidla, a to jeden horizontálny vodiaci výřez, v ktorom je posuvný, pevný excentrický čap rozšíreňého kíbového konca jedného ramena kružidla, a druhý horizontálny vodiaci výřez, v ktorom je posuvný, pevný excentrický čap rozšířeného kíbového konca druhého ramena kružidla, a vyznačuje sa tým, že jeho lamelová kulisa stláčaná rozšířenými kíbovými koncami ramien kružidla medzi dvoma kíbovými, súosovými, kuželovými čapmi má pevné rameno s osovým, vertikálnym, vodiacim výrezom, cez ktorý prechádza skrutka, ktorá spojuje vidlice rúčky kružidla v osi pod kíbovými, súosovými, kuželovými čapmi.The invention solves a device for stabilizing a compass handle, which has a lamellar link slidably placed between the widened joint ends of the compass arms and has two, opposite, horizontal guide cutouts formed in the link, between which the axis of the compass joint passes, namely one horizontal guide cutout, in which there is a sliding, fixed eccentric pin of the widened joint end of one compass arm, and a second horizontal guide cutout, in which there is a sliding, fixed eccentric pin of the widened joint end of the other compass arm, and is characterized in that its lamellar link, compressed by the widened joint ends of the compass arms between two articulated, coaxial, conical pins, has a fixed arm with an axial, vertical, guide cutout, through which a screw passes, which connects the forks of the compass handle in the axis under the articulated, coaxial, conical pins.

Description

Vynález rieši zjednodušené zariadenie na stabilizáciu rúčky kružidla, ktoré uTahčuje montáž kružidla a má váčšiu trvanlivost’.The invention provides a simplified device for stabilizing the compass handle which facilitates compass mounting and has a longer durability.

V terajšej technike známe a užívané zariadenie na stabilizáciu rúčky kružidla, ktoré pomocou fahadiel upevněných na ramenách kružidla stabilizujú rúčku kružidla, sú zariadenia zložité, ktoré majú mnoho súčiastok, čo sťažuje montáž kružidla a zvyšuje možnost’ poškodenia.Known and used in the art a device for stabilizing the compass handle that stabilizes the compass handle by means of handles mounted on the compass arms, the devices are complex, having many components, which makes compass assembly difficult and increases the possibility of damage.

Druhý druh kružidiel má na stabilizáciu rúčky kružidla, lamelu stláčanú medzi rozšířenými kíbovými koncami ramien kružidla, osovou, kíbovou skrutkou so skrutkovnicou a to má nevýhodu, že kíbovou skrutkou stlácané vidlice rúčky kružidla, stlácajú pod rozšířenými kíbovými koncami ramená kružidla a tým sa po čiastočnom opotřebení kíbu, ramená kružidla bočné vykyvujú.The second kind of compasses has for the stabilization of the compass handle, the slat compressed between the extended articulated ends of the compass arms, an axial, articulated screw with a helix, and this has the disadvantage that joint, the arms of the compass swing sideways.

Zariadenie na stabilizáciu rúčky kružidla, podfa vynálezu, je jednoduché, má málo súčiastok, Tahko sa montuje, Tahko sa nepoškodí a má dlhú trvanlivost.The device for stabilizing the compass handle according to the invention is simple, has few parts, is easy to assemble, is not damaged and has a long shelf life.

Podstatou vynálezu je lamelová kulisa, stláčaná rozšířenými kíbovými koncami ramien kružidla, medzi dvomi kíbovými súosovými, kuželovými čapmi, ktorá je opatřená pevným ramenom s osovýiň, vertikálnym, vodiacim výrezom cez ktorý prechádza skrutka, ktorá spojuje vidlice rúčky kružidla v osi pod kíbovými, súosovými, kuželovými čapmi. Zariadenie na stabilizáciu rúčky kružidla, podfa vynálezu, má málo súčiastok, tým Fahkú výrobu, ufahčenú montáž a je lačné. Tak vykazuje značný technický a ekonomický pokrok oproti v terajšej technike známým zariadeniam na stabilizáciu rúčky kružidla. Zobrazené je ako příklad, na priloženom výkrese v obr. 1 v nárysnom pohfade,SUMMARY OF THE INVENTION The present invention is based on a lamella plate, compressed by the extended articulated ends of the compass arms, between two articulated coaxial, conical pins, which is provided with a rigid arm with an axial axis. conical pins. The device for stabilizing the compass handle according to the invention has few components, thereby making it easy to manufacture, facilitating assembly and fastening. Thus, there is considerable technical and economic progress over the prior art devices for stabilizing the compass handle. It is shown, by way of example, in the accompanying drawing in FIG. 1 in a front view,

Claims

A device for stabilizing a compass handle having a sliding blade slidingly mounted between the extended articulated ends of the compass arms and having two horizontally opposed slots in the slider, between which the axis of the compass traverses, one horizontal guiding slot in which it is sliding, fixed the eccentric pin of the expanded joint end of one arm of the ironing device and the other horizontal guide cutout in which there is a sliding, solid eccentric pin extended in FIG.

2 in front view, FIG.

3 in side section and FIG.

4 is a plan view through a compass joint.

Between the widened joint ends of the compass arms 1, 2 there is a slidingly mounted slat 3 in which two horizontally guiding slots are formed opposite one another, between which the axis of the hinged, tapered pins 8, 9 extends. the expanded joint end pin 6 of one compass arm 1 and in the other there is a movable, rigid eccentric pin 5 of the extended joint end 2 of the second compass arm 2. The two pins 5, 6 move the blade plate 3 while swinging the compass arms 1.2, while the fixed arm 4 of the blade plate 3 has an axial, vertical guide slot through which a screw 7 connects the fork of the compass handle 10 in axis below the articulated, coaxial The present invention is based on a lamella plate 3 compressed by the expanded joint ends of the compass arms 1, 2 between two joint, coaxial tapered pins 8, 9, provided with a fixed arm 4 with an axial, vertical guide slot through which the screw 7 passes. The device for stabilizing the compass handle of the present invention is simple because only by means of a small lamella back plate - a small plate - and a screw 7 that connects the fork of the compass handle. keeps the compass handle 10 in the middle, axial position, thus having few parts, easy manufacturing, fahk assembly, is not easily damaged, has a long shelf life and thus shows considerable technical and economic progress over known devices.

the articulated end of the second compass arm, characterized in that the slats (3), compressed by the extended articulated ends of the compass arms (1, 2) between two articulated, coaxial, conical pins (8, 9), has a fixed arm (4) with axial, a vertical guide slot through which a screw (7) connecting the forks of the compass handle (10) in the axis below the articulated, coaxial, tapered pins (8, 9) extends.
