Description

Es ist bereits ein Flugspielzeug bekannt, bei dem sich während des Fluges ein Spielzeugteil durch Wirkung einer Zentrifugalkraft von einem Flugpropeller in Abhängigkeit von der Drehzahl löst. Diese Vorrichtung ist baulich sehr aufwendig und auch nicht bei Spielzeugen verwendbar, die keinen sich drehenden Teil aufweisen.A flying toy is already known in which a toy part is acted upon during the flight a centrifugal force from a flight propeller depending on the speed. This device is structurally very complex and cannot be used with toys that do not rotate Have part.

Weiterhin sind Schießspielzeuge bekannt, bei denen Geschosse mit einem kolbenförmigen Ansatz in einen zylinderförmigen Lauf eingeschoben und durch Federkraft abgeschossen werden können. Diese Spielzeuge besitzen eine Abzugvorrichtung, nach deren Lösen die Geschosse ruckartig abgeschleudert werden.Furthermore, shooting toys are known in which projectiles with a piston-shaped extension in a cylindrical barrel can be pushed in and shot off by spring force. These toys have a trigger device, after the release of which the projectiles are thrown off with jerks.

Erfindungsgemäß werden die beiden Spielzeugteile so ausgebildet, daß eine enge öffnung oder Undichtigkeit den Lufteinlaß in den Zylinderraum der durch die Federkraft auseinander gedrückten Teile derart regelt, daß die Auseinanderbewegung der Teile eine durch den im Zylinderraum .erzeugten Unterdruck bedingte Verzögerung erfährt.According to the invention, the two toy parts are designed so that a narrow opening or leakage the air inlet into the cylinder space of the parts pressed apart by the spring force in this way regulates that the moving apart of the parts caused by the negative pressure generated in the cylinder chamber Experiences delay.

Hierdurch wird eine Verzögerungseinrichtung für Spielzeuge vorgeschlagen, die sehr einfach aufgebaut ist und eine universelleAnwendungsmöglichkeit bietet. Sie ist anwendbar zur Verwirklichung von mehrstufigen Spielzeugraketen oder Flug-, Fahr- oder Schwimmspielzeugen mit nach einer gewissen Zeit sich lösenden Raketen, aber auch zur Verwirklichung von Wurfspielzeugen oder Scherzartikeln mit sich lösenden Teilen.In this way, a delay device for toys is proposed which is very simply constructed and offers a universal application. It is applicable to the realization of multi-level Toy rockets or flying, driving or swimming toys with loosening after a certain time Rockets, but also to make throwing toys or joke articles with parts that come loose.

Die Abschnellvorrichtung mit Verzögerungswirkung besteht aus einem Zylinder und einem Kolbenglied und vorzugsweise einer innenliegenden Druckfeder, die bestrebt ist, die beiden Teile voneinander weg zu bewegen. Einer der beiden Teile, vorzugsweise der umfassende Teil, besteht vorteilhaft aus einem elastischen Kunststoff. Die Verzögerungsvorrichtung kann auch eine Anordnung eines Auslaßrückschlagventils aufweisen, damit das Einschieben des einen Teils in das andere rasch erfolgen kann. In der Praxis weist aber die elastische Zylinderwand mit dem Dichtwulst bereits diese Wirkung auf. Durch den beim Einschieben entstehenden Überdruck läßt der Dichtwulst Luft entweichen. Die Verzögerungswirkung entsteht dadurch, daß die Federkraft in bezug auf den Zylinder- bzw. Kolbenquer ₁Schnitt und den größten Arbeitshub von Kolben und Zylinder so abgestimmt ist, daß die Feder die beiden Teile dank des im Innern nach der Freigabe entstehenden Unterdruckes nicht sofort voneinander abschnellen kann. Die Wandung des Zylinder- oder Kolbenteiles besitzt vorzugsweise eine kleine öffnung, durch die in dosierter Weise Luft bzw. bei Schwimmspielzeugen auch Wasser einströmen kann. Die Größe der öffnung bestimmt dann auch den Zeitpunkt, in dem sich die beiden Teile nach dem Loslassen bzw. Entriegeln voneinander abstoßen.The snap-off device with a delay effect consists of a cylinder and a piston member and preferably an internal compression spring which tends to move the two parts away from one another. One of the two parts, preferably the comprehensive part, advantageously consists of an elastic plastic. The delay device can also have an outlet check valve arrangement so that one part can be pushed into the other quickly. In practice, however, the elastic cylinder wall with the sealing bead already has this effect. The sealing bead allows air to escape due to the overpressure generated when it is pushed in. The delay effect arises from the fact that the spring force in relation to the cylinder or piston cross ₁ section and the largest working stroke of piston and cylinder is coordinated so that the spring does not immediately snap off the two parts thanks to the negative pressure generated inside after the release can. The wall of the cylinder or piston part preferably has a small opening through which air or, in the case of swimming toys, water can flow in in a metered manner. The size of the opening then also determines the point in time at which the two parts repel each other after being released or unlocked.

ao ausgeführt. Der durch die innenliegende Feder 2 abschnellbare Raketenkörper.3 faßt über das Kolbenteill und besitzt hinten Lufteinlaßschlitze 4, so daß entsprechend der Länge der Lufteinlaßschlitze noch eine gewisse Führungslänge für die Rakete auf dem Kolas benteil für die eigentliche Abschnellphase gegeben ist. Am Abschußgesteiii ist eine kleine Luftöffnung la vorgesehen, die die Luft langsam in das Innere des Teiles 1 einströmen läßt.ao executed. The rocket body 3, which can be snapped off by the internal spring 2, grips over the piston part and has rear air inlet slots 4, so that according to the length of the air inlet slots another certain guide length for the rocket on the Kolas bsteil is given for the actual snap-off phase. A small air opening la is provided on the launcher, which slowly lets the air into the interior of the Part 1 can flow in.

In Fig. II ist eine ähnliche Einrichtung wie in Fig. I dargestellt. Für die entsprechenden Teile sind gleiche Bezugszeichen eingesetzt, jedoch ist hier oben in den Raketenkörper 3 noch eine obere Raketenstufe 5 lose eingesteckt. Außerdem ist der Raketenkörper 3 durch ein Zugmittel 6 am Gestellkörper 1 gefesselt. Ferner besitzt das Gestell ein unter Federeinfluß stehendes Riegelglied 7 zum Arretieren und Freigeben des Raketenkörpers 3. Nach dem Lösen des Riegelgliedes 7 startet die Rakete 3 und 5. Nach einer gewissen Flugzeit hält das Zugmittel den unteren Raketenkörper 3 an, so daß die obere Raketenstufe allein weiterfliegt. Die Länge des Zugmittels in Beziehung zur Kraft der Feder 2 und dem Gewicht der Raketenstufen 3 und 5 ist so abgestimmt, daß die Trennung der Teile der Rakete erfolgt, wenn sich die Zweistufenrakete noch in vollem Aufwärtsflug befindet. Der Raketenkörper 3 mit dem mit seiner Wandung den Kolbenteil 1 zylinderförmig umfassenden Teil hat den Vorzug, daß sich, insbesondere bei Anordnung eines Dichtwulstes 8, eine durch die Unterdruckwirkung günstige Abdichtwirkung ergibt, insbesondere, wenn der Teil 3 aus einem elastischen Kunststoff besteht. Am Abschußkörper 1 ist noch eine kleine Luftöffnung 1 a vorgesehen, die die Luft langsam in das Innere des Teiles 1 einströmen läßt.In Fig. II a similar device as in Fig. I is shown. The same reference numerals are used for the corresponding parts, but here an upper rocket stage 5 is loosely inserted into the rocket body 3. In addition, the rocket body 3 is tied to the frame body 1 by a traction device 6. The frame also has a spring-loaded locking member 7 for locking and releasing the rocket body 3. After releasing the locking member 7, the rocket 3 and 5. After a certain flight time, the traction device stops the lower rocket body 3, so that the upper rocket stage alone flies on. The length of the traction means in relation to the force of the spring 2 and the weight of the rocket stages 3 and 5 is coordinated so that the separation of the parts of the rocket takes place when the two-stage rocket is still in full upward flight. The rocket body 3 with the part encompassing the piston part 1 in the shape of a cylinder with its wall has the advantage that, especially when a sealing bead 8 is arranged, the result is a sealing effect which is favorable due to the negative pressure effect, especially when the part 3 consists of an elastic plastic. A small air opening 1 a is provided on the launching body 1 and allows the air to flow slowly into the interior of the part 1.

Claims

In Fig. III a joke article is shown. The body of a figure, which can be set up in a fixed position and is provided with a cylinder wall 10, is designated by 9. 1 is again the snap-off spring located therein, which can be provided with a second body 11 at the front. The actual head is inserted with its piston-shaped part 12 so that it can be displaced in an airtight manner into the cylinder opening of the body. Air inlet slots 4 are also provided here again. A small air inlet opening la is attached to the side of the body 9. The attraction of playing lies in the fact that after inserting the body a certain short time elapses until the head suddenly flies out of the body. A stop can also be attached so that only the neck is lengthened. When parts 3, 5, 12 (Fig. I to III) snap out, a firing sound is heard at the same time. This is due to the air suddenly flowing into the vacuum from outside. FIG. IV shows a pistol with a projectile that can be pushed into the barrel and a compression spring located inside, as well as a side air opening. The projectile 13 again has louvres-4. A small air opening on the side of the barrel allows the bullet to be kept in the barrel for longer by placing a finger or to influence the triggering of the shot. This toy has the appeal of the delay arrangement of the firing sound and is very inexpensive to manufacture because it consists of only two parts and a spring, one end of which is clamped either to the gun body or to the projectile. "In Fig. V a projectile is in the form The handle 14 forms a part with the piston. The hand grenade head 15 is cylindrical. Inside there is again a compression spring 2. The head 15 has air inlet slots 4 on its edge and a small air inlet opening la on its bottom. VI, the body of an aircraft that can be detached, for example by means of a rubber cord, is designated by 16. In the body of the aircraft there are one or more cylindrical bores 17 with a compression spring 2 and a piston-shaped rocket 18 with air inlet slots 4 inserted from the front There is a small air inlet opening 1a. Several missiles can also be arranged be. In addition, a locking device can be attached to the missile in the aircraft, which is when snapping, z. B. by slacking off the elastic, solves. FIG. VII shows a swimming toy in the form of a buoyant submarine 19 which, for example, has one or more plug-in torpedoes 20 at the front, similar to the embodiment described in FIG. VI. After the torpedoes 20 have been pushed in against the springs inside and the submarine has been pushed, the torpedoes are automatically popped off the toy after a certain time. These torpedoes can also be made buoyant. In this case, water flows into the cylinder space, which determines the point in time of the deceleration. In Fig. VIII a driven by spring mechanism toy tank is shown, in the tube of a projectile 21, similar to the embodiment according to Fig. VII, is inserted. A catapult pistol 22 is shown in FIG. IX. It has a compression spring 23 and a trigger lever 27 provided with two locking lugs 24, 25 under the influence of a spring 26. The lug 25 engages behind the first stage 28 and the lug 24 the second stage 29 of a two-stage rocket. In the body 28 there is the compression spring 2 and a displaceably mounted guide part 30, the front part 31 of which is loosely inserted in the body 29 in the second stage. The small air inlet opening in the wall of the body 28 is again designated by la. Air inlet slots 4 are missing here because the part 30 takes over the leadership of the front step 29 during the snap-off process. In the missile body 29 is the replica of a space body 32, for. B. in the shape of the "Sputnik", loosely embedded against the action of a spring 33. The spherical body of the »Sputnik« is hollow and made of foam plastic. The two antennas 34 of the "Sputnik" are in the longitudinal direction. In Fig. X, the leadership of the rocket in the catapult pistol is drawn in cross section. A thickening 35 on the outer edge of the tail fins is overlapped by the strips 37 of the catapult. The attraction of this toy lies in the fact that the shooting up of the "Sputnik" is really imitated by the toy. After actuating the launch lever 27, the two-stage rocket is released. After a time predetermined by the device, the second stage then separates from the first, which then returns to earth. When the steps are separated and the upper step snaps off, the light "sputnik", which is designed as a float, is ejected and slowly floats back to the earth while — the second step falls again earlier.
