Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sphere launching apparatus for projecting a sphere such as a marble with a pair of flipping pieces.

[0002]

2. Description of the Related Art As a toy equipped with this kind of sphere launching device, there is known a toy disclosed in Japanese Patent Application No. 7-111313. This sphere launching device accommodates a sphere such as a marble between a pair of elastic playing pieces, and then forcibly pushes the sphere from the base side of the playing piece by an extruding member to thereby push the tip of the playing piece. The ball is expanded against the resilience, and the ball is ejected from the tip of the resilient piece by the elastic restoring force. At this time, an adjusting member for adjusting the resilience of the playing piece was attached to the base of the playing piece, and the flying distance of the sphere was changed by changing the resilience of the playing piece.

[0003]

However, in the above-described launching apparatus, in order to change the flight distance, the adjusting member must be changed and remounted, and the flight distance cannot be easily changed.

[0004] It is an object of the present invention to solve the above-mentioned problems and to provide a sphere launching device capable of easily changing the flight distance of a sphere.

[0005]

In order to solve the above-mentioned problems, a sphere launching apparatus according to the present invention has at least a pair of flipping pieces inside a launching cylinder, accommodates a sphere between the flipping pieces, and pushes out the ball. A sphere launching device that forcibly pushes out a sphere contained between flipping pieces by a member, and that ejects the sphere from a launch cylinder by an elastic force when a tip of the flipping piece expanded at the time of extrusion is restored. The side face of the piece is exposed from the launching cylinder, and the repelling force of the piece is adjusted by sliding along the longitudinal direction of the piece while engaging with a part of each outer surface of both pieces. An adjustment member is arranged.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

1 (a) and 1 (b) show a spherical launching device, and reference numeral 1 denotes a launching cylinder. The launching cylinder 1 is formed in a rectangular tubular shape and shoots a sphere 3 such as a marble from a launching port 2 at the tip thereof. Openings 4 are formed on both sides in the longitudinal direction, and project laterally from both sides of a rear end. Thus, a support plate 5 is formed, and a flipping member 6 is attached inside. A supply hole 7 for supplying the sphere 3 is provided on the rear upper surface of the firing cylinder 1.
Are formed.

As shown in FIG. 2, the flipping member 6 is made of an elastic synthetic resin and is formed in a substantially U-shape from a pair of flipping pieces 8 on both sides and a connecting portion 9 connecting the bases of the flipping pieces 8 to each other. The tip 8a of each hitting piece 8 is located in the vicinity of the launch port 2, and the connecting portion 9 is fixed to the launch cylinder 1 with a screw 10.

The tip 8a of the hitting piece 8 is formed so as to be curved inward, and the interval between the tips 8a is formed to be smaller than the diameter of the sphere 3. Further, engaging projections 11 are formed on both side surfaces so as to project at predetermined intervals.

An extruding member 12 is provided at the rear of the firing cylinder 1 so as to be slidable back and forth. This pushing member 12
Is formed in a substantially U-shape, and its tip 12a is arranged so as to come into contact with the rear surface of the sphere 3 housed between the flipping pieces 8, and is constantly urged rearward by a spring 13.

Reference numeral 15 denotes an adjusting member. The adjusting member 15 is formed in a rectangular cylindrical shape, is loosely fitted to the firing cylinder 1, and is slidably attached to the front and rear. The adjusting member 15 is provided with a retaining member 16 protruding from both sides of the distal end of the firing cylinder 1.
And the support plate 5 at the rear end, so that it does not fall out of the launch tube 1. Stabilizers 17 are formed on both sides of the adjusting member 15 so as to be engaged with the engaging projections 11 of the flipping member 6 to determine the front and rear positions of the adjusting member 15.

In the sphere launching apparatus having the above configuration, the sphere 3
Is fired, the adjustment member 15 is first slid back and forth, and stopped at the position where the stabilizer 17 is engaged with the engagement projection 11. Next, after the sphere 3 is supplied from the supply hole 7 to between the hitting pieces 8, the pushing member 12 is pushed forward against the spring 13 with the thumb while holding the support plate 5 as shown in FIG. . The sphere 3 between the flipping pieces 8 is pushed by the pushing member 12 and is forcibly pushed out between the flipping pieces 8, so that the tip 8a of the flipping piece 8 expands against its elastic force. At the moment when the maximum diameter (diameter) exceeds the tip 8a, when the playing piece 8 narrows due to its elastic restoring force, the sphere 3 moves from the tip 8a of the playing piece 8
Is ejected, and jumps out of the launch port 2. At this time, FIG.
As shown in (a), when the adjusting member 15 is retracted most and fired, the playing piece 8 is pushed right and left with the front end 15a of the adjusting member 15 as a fulcrum. It is in a state where it is easy to expand because it is long, and since the elastic restoring force after expansion by the pushing of the pushing member 12 is not large, the resilience is small and the flight distance is short.

On the other hand, as shown in FIG. 3 (b), when the adjusting member 15 is slid forward and fired, the distance L from the front end 15a to the tip 8a becomes shorter, so that when the adjusting member 15 is In this state, it is difficult to expand the ball, the elastic restoring force after the expansion is increased, and the resilience of the adjusting member 15 for projecting the sphere 3 is increased as compared to when the adjusting member 15 is located rearward.

As shown in FIG. 4A, the flipping member 6 may be formed by a flipping piece 31 having no engaging projection. As a result, the position of the adjustment member 32 can be slid steplessly without any restrictions, and the flight distance of the sphere can be changed steplessly.

Further, as shown in FIG.
A rack 34 is formed in the longitudinal direction on the upper surface of the adjusting member 3.
5, a ratchet 36 that meshes with the rack 34 may be formed. Thus, the set position of the adjustment member 35 can be finely changed, and the set position does not shift, and a stable flight distance can be secured.

Then, as shown in FIG.
Is formed in a manner simulating a robot, the launching barrel 1 is disposed through the body 37, and the body 2 is formed so as to be slidable back and forth with respect to the launching barrel 1. The formed stabilizer 38 may be stopped at an appropriate position on the launching cylinder 1. This allows the robot to launch the sphere as if by changing its flight distance, and the launch device can be easily incorporated into a small-sized toy, thereby increasing the added value of the toy.

In the above-described launching apparatus, the flipping member is constituted by a pair of flipping pieces. However, as shown in FIGS. The piece 41 may be formed. As a result, the sphere is ejected by two pairs of impacting pieces, and the flying distance of the sphere can be increased as a whole.

[0018]

According to the sphere launching device of the present invention, the adjusting member is slid while engaging with the flipping piece, and the position of engagement with the flipping piece is changed to change the resilience of the flipping piece. The flying distance of the launched sphere can be easily changed, and the play can have a wide range. In addition, it is not necessary to separately attach and detach a component for adjustment to the flipping portion in order to change the flight distance, thereby eliminating the troublesome management of the component and the trouble of attaching and detaching.
