Description

A device for limiting an angle change and a toy comprising such device
The invention relates to a device for limiting an angle rotation as featured in the introductory part of claim 1 and a toy comprising such device.
It is known to manufacture a device for limiting an angle rotation by letting a first part be rotatable relative to a second part in such a manner that the two parts can be turned less than 360° relative to each other. Such devices are typically manufactured such that the one part comprises an annular groove which is interrupted over a small or large portion of the circumference whereas the second part is provided with a tenon that is in engagement with said groove, whereby the two parts are able to rotate relative to each other over an angle rotation of up to approximately 360° depending on the extent of the interruption of the groove.
If it is desired to manufacture a device whereby it is possible to carry out an angle rotation of more than 360°, this could be accomplished by combination of a plurality of said devices in succession whereby the possible angle rotation corresponds to the sum of the individual angle rotations. However, this results in a relatively complex construction with many parts that have to be rotatable relative to each other.
It is the object of the present invention to provide a device for limiting an angle rotation of more than 360°, said device being of more simple construction than the known devices .
This is obtained by configuring the device described above as featured in the introductory part of claim 1. Hereby a very simple device is obtained for limiting a rotation to more than 360°, said device comprising in reality only three parts. Moreover it is possible to con- figure the device such that it occupies only little space since the three parts can be configured as relatively flat elements.
According to a preferred embodiment, the spiral groove consists of an depression configured in the first part, and the engagement portion consists of a tenon that protrudes from the slide element and which can engage with said depression.
The two stops of the spiral groove may be in the form of each their end wall of the indention that constitutes the spiral groove, which makes the construction particularly simple .
The invention also relates to a toy as featured in the introductory part of claim 4.
Such toy comprising a first part with a music box and a second part which is in engagement with the winder shaft of the music box is known, ia from US patent No 4,573,939, that features a toy with an upper part and a lower part that can be rotated relative to each other, said music box being windable when the two parts are rotated relative to each other.
There is no limitation to the angular rotation in the prior art toys which means ia that the internal spring of the music box can be completely biased when the music box is wound up. This entails, on the one hand, a risk of damaging the music box by subjecting it to too heavy winding and that, on the other, at the outset it plays its melody very fast due to the very tight spring.
Also, the rate of playing decreases gradually in order to finally discontinue completely when the spring is no longer able to drive the music box. It is possible with the prior art devices to force the music box to continue to play by forcing the winder shaft in the playing direction with the ensuing risk of damaging the music box.
By configuring the toy as featured in the characterising part of claim 1, a toy is obtained with a music box that cannot be damaged in the ways described.
If, furthermore, the music box is wound up slightly prior to its positioning in the toy, it is obtained that the spring of said music box never becomes so slack that it is unable to operate the music box. This means that the playing speed does not decrease towards the end, but is merely interrupted when the spiral groove is reached.
Nor will it be possible to over-load the spring of the music box, since the winding-up is restricted by the spiral groove.
Thus, it is possible with the invention to configure the toy such that the playing of the music box melody takes place only at the middle - approximately constant - section of the spring characteristic. Hereby playing at con- stant rate is achieved.
Preferably, the spiral groove consists of a depression provided in the first portion of the toy, whereas the engagement portion consists of a tenon that protrudes from the slide element and which is able to engage with the depression. In a preferred embodiment, the first portion comprises a disc with a central opening, wherein said music box is attached to the one side of the disc with the winder shaft extending through said central opening while the spiral groove is provided on the other side of the disc.
The two stops of the spiral groove advantageously comprise a tenon that extends towards the second portion, said tenon being arranged outside the spiral groove, and the slide element being provided with a protruding edge that is able to engage with the tenon. The advantage of configuring the device in this manner consists in a reduction of the risk of breaking some of the constituent elements of the device as the force that can be applied to the engaging parts will decrease the farther away from the axis of rotation they are placed.
In order to prevent axial displacement along the axis of rotation between the first part and the second part, the above-mentioned disc is preferably provided with a male element that protrudes towards the second part for snap- locking with a complementary female element on the second part .
The winding element is preferably configured with a square cross section, and the second element is provided with a corresponding square recess that can receive the winder shaft.
According to a preferred embodiment, the toy is configured as a toy animal, wherein the first element is constituted by the top part of the toy animal whereas the second element is constituted by the lower part of the toy animal. The invention will now be explained in further detail with reference to the drawings, wherein
Figures la-Id are schematic explanatory views of a device for limiting the angle rotation in accordance with the invention, and
Figure 2 illustrates a device for limiting an angle rotation applied in a toy with a music box.
Figures la-la schematically depict a device for limiting an angle rotation according to the invention, said device comprising a first element 1, a second element 2, and a slide element 3.
The first element 1 comprises a spiral groove 4 that, in the embodiment shown, extends three times about the axis of rotation A. In the embodiment shown, the groove 4 is constituted by a through-going slot in the first element 1.
The second element 2 is shown as a closed frame and comprises an internal guide 5 for the slide element 3 which displaceably arranged relative to the second portion 2.
The first element 1 and the second element 2 are rotata- bly arranged relative to each other about the axis of rotation A.
On the side that faces towards the first element 1, the slide element 3 is provided with a tenon 6 that engages with the spiral groove 4. The first element 1, the second element 2 and the slide element 3 are, by not shown means, secured axially along the axis of rotation A rela- tive to each other thereby preventing the slide element 3 from disengaging from the guide 5 in the second element 2, and from the spiral groove 4 in the first element.
The device for limiting an angle rotation is, in Figure la, shown in its one extreme position, wherein said tenon 6 abuts on a first stop 7 (cf. Figure lb) which, in the embodiment shown, consists quite simply of the one end wall of the spiral groove 4.
In Figure lb, the second element 2 is pivoted 90° about the axis of rotation A relative to the first element 1, whereby the slide element 3 is shifted a small distance outwards due to the engagement of the tenon 6 with the spiral groove 4.
Figure lc illustrates the position of the slide element 3 when the second element 2 has been pivoted a full round (360°) , and it will appear that the slide element 3 has been displaced a further distance outwards.
In Figure Id the device for limiting an angle rotation is shown in its second extreme position wherein the tenon 6 abuts on a second stop 8 (cf. Figure lb) which, like the first stop 7, is also constituted by an end wall of the spiral groove 4.
Thus, in the embodiment shown, the second element 2 can be rotated three rounds (1080°) relative to the first element 1 corresponding to the expanse of the spiral groove 4 about the axis of rotation A.
Figure 2, illustrates a concrete use of the device for limiting an angle rotation wherein it is arranged in a toy animal 9 with a music box 10. The music box 10 is of the type that is provided with a rotating drum 11 having protruding tenons 12 that are able to engage with a metal rack 13 provided with teeth 14 in different lengths for the playing of different tones. By means of a winder shaft 15, the music box can be wound up, a spring being biased within the music box. The spring can subsequently drive the drum 11 whereby a melody is played by the engagements between the tenons 12 of the drum 11 and the teeth 14 of the metal rack 13.
The toy animal 9 consists of an upper part 16 and a lower part 17 that are rotatably arranged relative to each other. The music box 10 is secured relative to the upper portion 16 whereas the winder shaft 15 is in engagement with the lower portion 17 thereby enabling the music box 10 to be wound up by turning of the upper portion 16 relative to the lower portion 17.
The top portion 16 comprises an internal disc 18 which is, on its top face, provided with ribs 19 that secure the music box 10 relative to the upper portion 16. The disc 18 is, on the lower face, configured with a spiral groove 4, and at the centre a downwardly extending, tubular male element 20 is arranged for snap-locking engagement with a complementary female element 21 configured in the bottom portion 17 in such a manner that the upper portion 16 and the lower portion 17 are able to rotate relative to each other about the axis of rotation A.
Additionally, the lower portion 17 is provided with a recess 22 which is complementary to the winder shaft 15 which is hereby in permanent engagement with the lower portion 17. According to a preferred embodiment the recess 22 and the winder shaft 15 have a square cross section.
A slide element 23 is provided between the lower portion 17 and the disc 18. The slide element is arranged to be laterally displaceable in the lower portion 17, the latter being provided with a guide with is not shown in detail.
The slide element 23 is provided with an upwardly extending tenon 24 which is in engagement with the spiral groove on the bottom side of the disc 18, and furthermore it has two protruding edges 25,26 that are able to engage with one or more tenons 27 that extend (s) downwards at the edge of the disc 18. The tenon 27 has the same function as the stops 7 and 8 shown in Figures la-Id.
The functioning of the device for limiting an angle rotation used in the toy animal 9 corresponds exactly to the principle described with reference to Figures la-Id while it differs constructively by the tenon 27 which is provided at the edge of the disc 18 and the edges 25 and 26 that are able to engage with said tenon 27.
When the upper portion 16 is rotated clockwise to wind up the music box 10, the slide element 23 is shifted to the right in Figure 2 until the edge 26 abuts tangentially on the tenon 27 on the disc 18.
During playing, the internal spring of the music box 10 rotates the upper portion 16 anti-clockwise whereby the slide element 23 is shifted to the left until the edge 25 abuts tangentially on the tenon 27. Preferably, the spiral groove 4 has an extent that corresponds to 3-4 rounds of the upper portion 16 relative to the lower portion 17, since this has been found to be suitable for a music box 10 of the kind used. However, nothing prevents the spiral groove 4 from extending over more or fewer rounds about the axis of rotation A. Music boxes 10 of the type shown have a propensity to playing fast when the internal spring is biased, ie when the music box 10 is fully wound up, whereas they play slowly when the spring can barely drive the drum 11 at the end of the playing. By use of a device for limiting an angle rotation in connection with a music box 10, eg as shown in Figure 2, it can be obtained that the playing of music box 10 is effected only by means of the central portion of the spring's spring force whereby a more con- stant rate of playing for the music box 10 is achieved. This is achieved by biasing the spring prior to arrangement thereof in the toy animal 9 to such extent that, following complete playing, it is still biased. Hereby it is the device for limiting an angle rotation that stops the playing and not the weak spring force of the music box 10.
By having stops at both ends of the device for limiting and angle device, it is further obtained that the spring cannot be over-loaded which might otherwise be detrimental to the music box 10.
In the preceding, the spiral groove 4 is described as a depression in which a tenon 6,24 on the slide element 3,23 can be displaced over the entire length of the groove 4. However, the spiral groove can also be configured as an elevation simultaneously with the slide element featuring two tenons that catch the elevation. Yet other embodiments of the spiral grooves are perceivable without thereby deviating from the idea behind the invention.
