A gyro assembly according to an embodiment of the present invention will be described with reference to fig. 1 to 10. In the following description, references to orientations or positional relationships of "front", "rear", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc., are based on the orientations or positional relationships shown in the drawings, are merely for purposes of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore are not to be construed as limiting the present invention.

FIG. 1 is an assembled schematic view of a top assembly according to one embodiment of the invention; FIG. 2 is an exploded schematic view of a top assembly.

As shown in fig. 1 and 2, an embodiment of the present invention provides a gyro assembly. The top assembly may generally include a top 200 and a mount 100 for placing the top 200. The mount 100 includes a plurality of jaws (e.g., jaw 511, jaw 521, jaw 531 in fig. 1). Referring to fig. 1, when a user does not need to use the top 200, the top can be placed on the mounting base 100 horizontally, so that the plurality of claws can clamp different parts of the periphery of the top 200 under the action of elastic force, so as to fix the position of the top 200. When a user wants to take down top 200 to play a game, as shown in fig. 2, an external force can be applied to the jaws, so that the jaws overcome the elastic force to move away from the periphery of top 200 (i.e., move it radially outward) under the action of the external force, and the constraint of top 200 is released.

FIG. 3 is an exploded schematic view of mount 100; FIG. 4 is a schematic diagram of a top assembly in a state where three jaws clamp top 200; FIG. 5 is a schematic diagram of the top assembly in a state where three jaws release the top 200; fig. 6 is an exploded view of the chassis 110, the sliding support 510, and two rotating supports.

As shown in fig. 3-6, in one particular embodiment, the mount 100 includes a chassis 110, a sliding bracket 510, a resilient member, and two rotating brackets 520, 530. The chassis 110 forms the main body of the mount 100 for mounting the sliding bracket 510 and the two rotating brackets 520, 530. The sliding bracket 510 is reciprocally and translationally provided on the chassis 110 in its own length direction (i.e., in the X-axis direction of the coordinate system shown in fig. 3), and a first end (X-axis forward end) thereof forms a claw 511. The elastic member is mounted to the base plate 110 for applying an elastic pre-tightening force to the sliding bracket 510 such that the jaw 511 thereof has a tendency to move toward the center (i.e., origin O of the coordinate system) of the base plate 110 so as to press against the top 200. Two rotating brackets 520, 530 are provided on both sides of the sliding bracket 510, respectively. The middle part of the rotating bracket 520 is rotatably installed on the chassis 110 around a vertical axis Z1, a first end of which is formed with a jaw 521 and a second end of which is movably connected to the sliding bracket 510. The middle part of the rotating bracket 530 is rotatably mounted on the chassis 110 around a vertical axis Z2, a first end of the rotating bracket is formed with a claw 531, and a second end of the rotating bracket is movably connected to the sliding bracket 510. The sliding support 510 can drive the two rotating supports 520 and 530 to rotate when translating, so that the three clamping jaws 511, 521 and 531 synchronously approach to or separate from the center of the chassis 110.

As shown in fig. 6, the elastic element is a second compression spring 540. The chassis 110 has a spring support 111 mounted thereon. The sliding bracket 510 has a stud 515 near its second end, and a second compression spring 540 is fitted over the stud 515 with its end abutting against the spring support 111 to complete the installation.

Fig. 4 illustrates a state in which top 200 is clamped, and an outer contour of top 200 is shown by a broken line circle S1. In fig. 4, the jaws 511, 521, 531 clamp the top 200, and the sliding support 510 has a tendency to move in the negative direction toward the X-axis by the elastic force, so that the jaws 511 clamp the periphery of the top 200. The second end of the rotating bracket 520 has a tendency to move in the negative direction toward the X-axis under the driving of the sliding bracket 510, so that the whole body of the rotating bracket has a tendency to rotate counterclockwise, and the clamping jaw 521 clamps the periphery of the top 200. The second end of the rotating bracket 530 has a tendency to move in the negative direction toward the X-axis under the driving of the sliding bracket 510, so that the whole body has a tendency to rotate clockwise, and the clamping jaw 531 clamps the periphery of the top 200.

Fig. 5 illustrates a state when top 200 is released. Based on the state of fig. 4, the user overcomes the elastic pre-tightening force of the elastic element, and pushes the sliding support 510 forward along the X-axis, so that the claw 511 of the sliding support is far away from the periphery of the top 200. The second end of the rotating bracket 520 is driven by the sliding bracket 510 to move forward toward the X-axis, so that the whole rotates clockwise, and the clamping jaw 521 thereof is far away from the periphery of the top 200. The second end of the rotating bracket 530 is driven by the sliding bracket 510 to move forward toward the X-axis, so that the whole body rotates counterclockwise, and the claw 531 thereof is far away from the periphery of the top 200, and finally moves to the state of fig. 5, so that the top 200 is released.

As shown in fig. 10, the periphery of top 200 is inwardly provided with a circumferentially extending groove 211 to allow a plurality of jaws to be snapped in so as not to disengage from mount 100.

The connection structure of the rotating brackets 520, 530 and the sliding bracket 510 is described below with reference to fig. 6. As shown in fig. 6, the middle portions of the two rotating brackets 520, 530 have pivot holes 523, 533, respectively, so as to be opposed to the chassis 110 provided with two mounting holes 117 (the central axes of the two mounting holes, that is, the aforementioned axes Z1 and Z2), which are connected by a pin (not shown), so that the two rotating brackets 520, 530 can rotate about the axes Z1 and Z2, respectively. The second ends of the two swivel brackets 520, 530 are provided with elongated openings 522, 532, respectively. The sliding support 510 is provided with two vertically extending mounting posts 513, each mounting post 513 being movably inserted into a respective one of the elongated openings 522/532. As the sliding support 510 translates, the mounting post 513 is moved within the elongated opening 522/532 to rotate the rotating support about the axis Z1/Z2.

Specifically, two mounting posts 513 are located on the upper and lower sides of the second end of the sliding bracket 510, respectively (the lower mounting post 513 is hidden from view in fig. 6) so as to be coaxially disposed. The second ends of the two rotating brackets 530, 520 are located at the upper and lower sides of the sliding bracket 510, respectively, to match the corresponding mounting posts 513.

In addition, as shown in fig. 6, the chassis 110 is provided with a plurality of vertically extending limiting posts 118, the sliding support 510 is provided with a plurality of elongated limiting holes 512 extending parallel to the length direction thereof, and each limiting post 118 is inserted into one elongated limiting hole 512 so as to limit the reciprocating translation range of the sliding support 510. The length of the elongated limiting hole 512 is the reciprocating translation range of the sliding support 510. Specifically, the sliding support 510 may include an oblong loop portion and a straight bar portion connected thereto as a whole. The oblong ring-shaped portion is provided with two elongated stopper holes 512 arranged along the two longitudinal directions perpendicular to the length direction of the sliding support 510 (i.e., the Y-axis direction of the coordinate system in fig. 4), and the straight rod-shaped portion is provided with two elongated stopper holes 512 arranged along the length direction of the sliding support 510. The four elongated limiting holes 512 are arranged in a Y-shape, so that the sliding support 510 can move more stably.

In some embodiments, top 200 may be mounted to both sliding and rotating brackets 510, 520, 530. However, in the preferred embodiment, as shown in FIGS. 2 and 3, the mount 100 is further comprised of a shroud 120. The cover plate 120 is covered on the chassis 110 to define a space for accommodating the sliding bracket 510 and the rotating brackets 520, 530 together with the chassis 110, so as to prevent the sliding bracket 510 and the rotating brackets 520, 530 from being exposed to the outside to affect the visual effect. Specifically, as shown in fig. 3, the cover plate 120 is provided with a plurality of screw holes 129, and the chassis 110 is provided with a plurality of mounting portions 119, which are provided with screw holes. Each screw hole 129 is opposed to one of the screw holes, and the cover plate 120 is fastened to the mounting portion 119 by a screw. The outer upper surface of the cover plate 120 has an area for allowing the top 200 to lie flat thereon. And, three openings 126 are formed in the cover plate 120 to allow three claws to protrude out of the cover plate 120 through the corresponding openings to prop against the periphery of the top 200, as shown in fig. 2.

Specifically, as shown in fig. 2 and 3, a cavity 121 for allowing the top 200 to be inserted therein may be formed at the upper side of the cover plate 120 so that the top 200 is just inserted into the cavity 121, and the circumference thereof contacts with the side wall of the cavity 121 to make the whole top assembly more beautiful. The three openings 126 are formed in the side wall of the cavity 121.

In some embodiments, as shown in fig. 2 and 3, a button 600 is provided on the cover plate 120, the outer end of the button 600 is exposed outside the cover plate 120, and the inner end abuts against the second end of the sliding support 510, so as to allow a user to push the sliding support 510 to move by pressing the button 600 when three jaws abut against the top 200, and release the restriction of the top 200 by the three jaws. Thus greatly facilitating the operation of the user.

Specifically, the cover plate 120 is provided with a blind hole 127 at the side and a through hole 1271 at the bottom wall thereof. The button 600 is telescopically disposed in the blind hole 127, and the post 610 at the rear thereof is extended into the inside of the cover plate 120 through the through hole 1271 to push the sliding bracket 510.

In some embodiments, as shown in fig. 2 and 3, the top assembly further includes a pop-up device. The bouncing device is configured to apply an upward elastic pre-tightening force to top 200 when top 200 is laid flat on mount 100 (as in fig. 1). After the constraint on the top 200 is released by the clamping jaws, the top 200 is sprung upwards, so that the top 200 is convenient to take down by a user, and the design is novel and ingenious.

Specifically, as shown in fig. 3, a central portion of the top surface of the mounting block 100 (which may be specifically the top surface of the cover plate 120) is recessed downwardly to form a central cavity 128. The pop-up device includes a support 310 and a first compression spring 320. The stand 310 is provided in the cavity 121 to be vertically translatable within a predetermined range, and has an upper surface for supporting a bottom center portion of the top 200. The bottom end of the first compression spring 320 abuts the bottom wall of the central cavity 128 and the top end abuts the bottom surface of the support 310 to exert an upward resilient preload on the support 310.

Fig. 7 is a schematic structural view of the holder 310; fig. 8 is a schematic cut-away view of the mount 310. For example, in fig. 3, 7 and 8, the support 310 may include a circular top wall 301 and a peripheral wall 302 extending downwardly from the periphery of the circular top wall 301. The peripheral wall 302 has a plurality of buckles 311, the side wall of the central cavity 128 is provided with a plurality of buckling holes 131, and each buckle 311 is inserted into a corresponding buckling hole 131 in a vertically movable manner. When the support 310 is pushed up to the highest point by the first compression spring 320, the buckle 311 is pushed against the top wall of the card hole 131, so that the support 310 cannot move up further, and the highest position of the support 310 is defined. The bottom wall of the central cavity 128 may be provided with a cross-shaped projection structure 1281 to allow the first compression spring 320 to be nested thereon. The bottom of the support 310 has a downwardly extending annular wall 3011 to fit over the first compression spring 320.

In some embodiments, the circular top wall 301 may be formed as a concave curved surface gradually recessed from the periphery to the center, such as a partial spherical surface, so that the top surface of the circular top wall 301 contacts the bottom (usually a revolving body) surface of the top 200 in a line contact manner, and the contact line is a circle located on a horizontal plane, so that the force of the circular top wall 301 on the points contacting the top 200 is quite uniform, and the circular top wall 301 can spring upwards along the vertical axis without being blocked in the concave cavity 121 and cannot spring.

FIG. 9 is a schematic structural view of a top illustrating its bottom structure; fig. 10 is a side view of a top.

As shown in fig. 1, 9 and 10, a top 200 of the present invention may generally include a disk body 210 and a circular support 220. The disk body 210 is a thin disk. The circular support 220 is formed in the center of the bottom surface of the disc body 210, is coaxially disposed with the disc body 210, and has a revolving structure with a radius tapered from the top to the bottom, and may be a cone or other revolving structure for contacting the ground to support the top 200 for rotation. Of course, the disc body 21 and the circular support portion 220 are preferably manufactured by an integral molding process. Let the diameter of the disc body 210 be a, and the distance from the top surface of the disc body 210 to the bottommost end of the circular support portion 220 be H. The inventor has proved through a large number of experiments that when A and H satisfy the condition that A/H is not more than 12 and not more than 15, the top 200 has good rotation stability and longer rotation time. When A/H is less than or equal to 12, the height of the gyroscope is higher, the gravity center is higher, and the gyroscope is not easy to stabilize at low speed. When A/H is more than or equal to 15, the height of the gyroscope is lower, the disc body 210 is closer to the ground, the viscous resistance of air between the disc body and the ground during rotation is larger, and the rotation time of the gyroscope is relatively shortened.

Further, let the distance from the bottom surface of the disc body 210 to the bottommost end of the circular supporting portion 220 be H1. The inventors have experimentally confirmed that H1 and H satisfy the following conditions: H1/H is more than or equal to 0.5 and less than or equal to 0.7, so that the top 200 has good rotation stability and longer rotation time. When H1/H is too small, the disc body 210 is close to the ground, the viscous resistance of air between the disc body and the ground is large during rotation, and the rotation time of the spinning top is relatively shortened. When H1/H is too large, the center of gravity of the gyroscope is high, and the gyroscope is not easy to stabilize at a low speed.

As shown in fig. 9 and 10, a plurality of ribs 230 uniformly distributed in the circumferential direction may be formed on the top 200. Each rib 230 extends from the edge of the bottom surface of the disc body 210 to the surface of the circular support 220, but does not extend to the bottommost end of the circular support 220 to avoid the rib 230 from touching the ground. The ribs 230 further lower the center of gravity of the top 200 without lowering the height of the disk 210.

As shown in fig. 1, the top center of the top 200 has a recess 260, and the recess 260 has a grip 261 crossed by two vertical plates so that a user holds the grip 261 to rotate the top without whipping with a string.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
