Description

[Detailed Description of the Invention] This invention mainly relates to an assembly type ball lifting device for lifting a ball from a low point in a ball path to a high point in the ball path in a ball rolling toy.

As the above ball rolling toy A
As shown in Figure 1, a large number of rail supports E are attached to arbitrary positions of several upright columns D, and a pair of wire-like supports E are attached to the supports E. The rails C are mounted at predetermined intervals to form a continuous desired ball path B, and the ball 16 is played by rolling from a high point to a low point on the ball path B. Incidentally, since the ball path B of this type of toy A can be freely set according to the player's preference, the ball lifting device can also freely set the height at which the ball 16 is lifted in accordance with the ball path B. You must do so.

This idea was made in view of the above points, and it allows the length of the belt that is stretched between the upper and lower pulleys to be set as desired, and also makes the ball holder attached to the belt removable. To provide an inexpensive assembly type ball lifting device which can arbitrarily set the height at which a ball is lifted, has a simple structure, and is easily assembled.

Hereinafter, embodiments of this invention will be described based on the drawings. In Figures 2 to 6, 1 is a case body consisting of a bottom plate 1a and a housing-like lid 1b with an opening at the lower end that is detachably placed over the bottom plate 1a, and is spaced apart in the width direction on the center of one end of the bottom plate 1a. A pair of supports 2 having a fitting hole 2a for the support column 11 is provided in a protruding manner, and a plate-shaped support member 3 is erected on one side edge adjacent to one of the supports 2. 3 extends to the other side and rotatably and detachably supports a support shaft 4. A small-diameter pulley 5 is fixed to the center of the support shaft 4, and a large-diameter pulley 6 is fixed to the tip of the support shaft 4, respectively. Furthermore, the bottom plate 1a
A pair of fitting plates 7 for attaching the motor 8 are installed vertically at intervals in the width direction near the other end of the top, the motor 8 is mounted between these fitting plates 7, and its drive shaft 8a is attached to the large diameter pulley 6 side. A small-diameter pulley 9 is fixed to the drive shaft 8a, and an endless annular transmission belt 10 is stretched between the small-diameter pulley 9 and the pulley 6 to rotate the motor 8. This allows the support shaft 4 to rotate via the belt 10.

Reference numeral 11 denotes a pair of pillars erected by fitting the base end into the support 2, and a pipe member 11a having a predetermined length.
By connecting through the joint member 11b, the height can be set freely.
A large-diameter pulley 12 is rotatably mounted between the upper ends of both columns 11 via a support shaft 13 that is detachably attached to both columns 11.

14 is the small diameter pulley 5 and the large diameter pulley 12
This belt 14 is an endless annular belt that is stretched between the belts, and the belt 14 is made by cutting a rod-shaped member 14a made of a flexible synthetic resin material such as urethane rubber into a predetermined length, and butt-joining both ends by heat welding or the like. Therefore, the length of the belt can be freely and easily adjusted according to the distance between the pulleys 5 and 12.

Reference numeral 15 denotes a ball receiver that can be attached to and removed from any position on the belt 14. As shown in FIGS. It has a structure in which a sphere receiving seat 15b corresponding to a part of the spherical surface of the sphere 16 is provided on the top surface of the distal side of the plate-like body 15, and the fitting groove 15a is configured such that the fitting groove 15a allows the ball receiving tool 15 to belt 14
It is formed to be inclined so that its tip points slightly upward when attached to the belt, and its base end is shaped into a constriction so that it can pass through the belt fitting grooves 5a and 12a of each pulley 5 and 12. There is. Therefore, the ball receiver 15 can be adjusted depending on the length of the belt 14 and the belt 1.
Belt 1 at appropriate intervals considering the rotation speed of 4, etc.
It will be installed on the 4th.

Reference numeral 17 denotes a pair of spherical guideways extending forward from the rear end in the longitudinal direction of the upper surface of the lid body 1b and spaced apart from each other in the width direction in correspondence with the spherical bodies 16;
Each guideway 17 is formed into a spherical stop 17a by gently inclining downwardly toward the front and sharply upwardly inclining the front end, and between both guideways 17 from the center of the front end of the lid 1b. An opening 18 is opened across the lower front part, and the support 11 is positioned within the opening 18 with the lid 1b placed over the bottom plate 1a, and the ball holder 15 attached to the belt 14 is placed in the opening 18. It is configured to be able to pass through the opening 18 and rotate.

In FIG. 2, reference numeral 19 denotes a battery device in which a battery is housed in a replaceable manner. This device 19 has a switch 20 at the upper end, and a conductor 8b from the motor 8 is connected to a terminal 19a at the lower end of the device 19. It is designed to do so.

Next, how the above embodiment is used will be explained.

Taking as an example the case where the device is used for the ball rolling toy A shown in FIG. After assembling the case body 1, the top of the upper pulley 12 is positioned between the open ends of the pair of rails C at the upper end of the spherical path B.
At the same time, the open ends of the pair of rails C at the lower end of the spherical path B are positioned at the rear end of the guide path 17 of the case body 1. Note that if the mounting holes 21 for the open ends of the rails C are formed at the upper end of each support 11 and at the rear end of the guideway 17, the rails C can be securely fixed.

Then, place the plurality of spheres 16 side by side on the guideway 17, turn on the switch 20, and turn on the motor 8.
When the belt 14 is rotated in the direction of the arrow,
The ball 16 located at the front end of the guideway 17 is placed on the receiving seat 15b of the ball receiving device 15, and the ball receiving device 15
The sphere 16 rises in a substantially horizontal state due to its own weight, and as the ball receiver 15 tilts forward and downward at the upper pulley 12 position, the sphere 16 transfers to the rail C at the upper end of the sphere path B and rolls due to its own weight. While moving, it comes to the lower end of sphere path B and returns to taxiway 1.
7 Move over. Further, the next ball 16 on the guide path 17 rolls toward the front end along the inclined surface, and is lifted upward by the next ball receiver 15.

In this way, the balls 16 that have rolled to the lower end of the ball path B are automatically and continuously transferred to the ball path B.
You can play by lifting it to the upper end and rolling it along the spherical path B. By arranging the ball holder 15 in the middle of the ball path B, by arranging the ball holder 15 of the device according to the present invention so that it faces the lifting path, the ball 16 in the middle of the path B can be lifted not only from the lower end of the path B but also to the upper end of the path B. It is also possible to send

As explained above, in the assembly type ball lifting device of this invention, both ends of a rod-shaped member made of a flexible synthetic resin material are butt-jointed so that the length of the belt, which is stretched between the upper and lower pulleys, can be arbitrarily set. The belt is shaped like an endless ring, and the structure allows the ball receiver to be detachably attached to any position on the belt, so the height at which the ball is lifted can be set arbitrarily, and the ball roller allows the user to freely create the ball path. When used in toys, the lifting height of the sphere can be set according to the created sphere path, so there are no restrictions on the creation of the sphere path, and the structure is simple and anyone can easily assemble or It has the advantage of being able to be disassembled and reducing manufacturing costs.
