Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to hopping, and particularly to hopping with a counter.

[Conventional technology]

It has been well known that jumping toys are equipped with a counter mechanism (Utility Model Publication No. 51-9944, Utility Model Number 56-994).
No. 38611).

However, as shown in Figure 1, the main
A handle provided on one side of the main pipe, a lower pipe slidably provided within the other side of the main pipe, and a handle provided externally on the lower pipe, interposed between the lower part of the step and the lower part of the lower pipe. However, there was no one that included a counter mechanism in the hopping consisting of a coil spring that held the lower tube in a predetermined position.

[Problem to be solved by the invention]

A counter mechanism is installed at the top of the hopping main pipe to advance the count by sending a rotary body with numbers displayed on the surface using a feed claw, and this feed claw is fed by a link provided between the lower pipe and the feed claw. In this case, when the step jumps and falls, a considerably large load is applied to the step, and the lower pipe greatly enters the main pipe, and the connecting rod is accordingly pushed upward strongly. Therefore, there is a risk that the connecting rod may damage the counter mechanism or the connecting rod itself.
It was considered difficult to commercialize it.

[Means to solve the problem]

The hopping of this invention includes a main pipe, a handle provided at the upper part of the main pipe, a step provided at the lower part of the main pipe, and a step provided slidably within the lower part of the main pipe, with the lower part protruding from the lower end of the main pipe. Hopping consists of a lower pipe provided at the main pipe, and a coil spring that is sheathed on the lower pipe and is provided between the lower part of the step and the lower part of the lower pipe to hold the lower pipe in place. A counter mechanism that is installed at the top and advances the count by sending a rotary body with numbers displayed on the surface with a feed pawl.It is stretched between the lower tube and the feed pawl, and the main tube compresses the coil spring. The piano wire is composed of a piano wire whose distal end rises relative to the main pipe 1 and operates the feed pawl when the feed claw is lowered.

[Effect]

When the user grasps the handle and jumps on the step, the main pipe 1 descends while compressing the coil spring 7, and the lower pipe 2 enters into the main pipe 1. The upper end of the piano wire attached to the lower tube 2 rises relative to the counter mechanism attached to the main tube 1, operates a feed pawl, and advances the count.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

The figure is a cross-sectional perspective view of essential parts showing the overall configuration of the present invention. In the figure, reference numeral 1 denotes a main pipe made of a strong material such as iron and having a hollow cylindrical shape, and a lower part of the main pipe 1 is slidable on the main pipe 1 and is equipped with an elastic means to be described later. A lower tube 2, which is also a component, is attached. Further, a handle 3 is fixed to the upper end surface of the main pipe 1 so as to have a T-shaped overall shape, and has rubber grips 4, 4 at both ends of the handle 3. On the other hand, a step 5 is fixed to the lower part of the main pipe 1, which is substantially parallel to the handle 3 and is formed so that both feet can be placed on it. Further, a rubber plug 6 is fitted to the lower end of the lower tube 2 to absorb the impact when landing from a jump.
Incidentally, below the step 5, the lower tube 2 and the coil spring 7, which constitute a resilient means, are provided in a configuration described below. That is, one end of the coil spring 7 is fused to the back surface of the step 5, and the other end is fused to the lower side of the lower tube 2, so that the lower tube 2 normally protrudes from the main tube 1. Note that 8 is a fixing part for fixing one end of a piano wire, which will be described later.

On the other hand, a hollow case 9 made of synthetic resin is attached to the upper part of the main pipe 1 as shown in the figure. Incidentally, the case 9 is composed of two members, a case half 9a and a case half 9b, and has a built-in counter mechanism 10 that can display the number of jumps. Reference numeral 11 denotes a rotary body whose cylindrical shape is divided into three parts, each of which is engraved with numbers 0 to 9 and capable of displaying three digits, and is linked to the rotation of a ratchet gear 12 attached to one side of the rotary body 11. It is designed so that it can be rotated one scale at a time. Furthermore, as shown in the figure, due to the spring action of the spring 13, the tip A of the U-shaped swinging lever 14 is always in contact with the pawl B of the ratchet gear 12, and is prevented from becoming distorted in the piano wire, which will be described later. Interlockingly, the swing lever 14 swings as shown by the imaginary line, and its tip A click-rotates the ratchet gear 12 by one pawl, causing the rotating body 11 to rotate intermittently. Also, as shown in the figure, feed claw 1
A straight rod portion 15 is provided at the lower part of the lower tube 2 so as to swing in the upper space of the rotating body 11, and this straight rod portion 15 and the fixed portion 8 provided at the lower part of the lower tube 2 are connected to each other.
A piano wire 16 for transmitting the compression operation of the elastic means 2 and 7 to the counter mechanism 10 is stretched between the two. Note that 17 is a knob, which is connected to the rotating body 1.
It is now possible to reset the number of jumps displayed in 1.

Next, the operation of the present invention configured as described above will be explained.

Now, when a child or the like grasps the gripping parts 4, 4 with both hands and jumps upward with both feet on the step 5 and lands, the lower tube 2 compresses the coil spring 7 due to the impact of landing, causing the lower tube 2 to compress the coil spring 7 and line up the imaginary line. Insert into main pipe 1 to the point shown in . As a result, the straight rod portion 15 of the feed claw 14 and the fixed portion 8
The distance between them is shortened, and the piano wire 16 is distorted as shown by the dotted line in the figure. At the same time, the swinging lever 14 uses its tip B to clickly rotate the ratchet gear 12 by one pawl, that is, advance the rotating body 11 by one graduation and swing to the position shown by the imaginary line. Next, due to the elastic force of the compressed coil spring 7, the lower pipe 2 protrudes from the main pipe 1 and returns to its pre-jump position, and in conjunction with this, the piano wire 16 and feed pawl 14 also become in the state shown by the solid line. . In this way, the rotating body 11 performs a click rotation every time a jump is performed, and eventually the number of consecutive jumps is displayed on the rotating body 11.

As described above, according to the present invention, the jumping toy is equipped with a counter mechanism that counts in conjunction with the firing of the jumping means, so there is no need to count the number of jumps while jumping as in the conventional toy. The number of times will be obvious at a glance.

In addition, since a piano wire is used as a connecting rod to transmit the sliding motion of the lower tube 2 to the counter mechanism, even if the sliding distance of the lower tube 2 is large, the distortion of the piano wire will prevent
There is no possibility that the counter mechanism will be damaged or the connecting rod itself will break.

〔effect〕

According to the present invention, it is possible to provide a hopping with a counter mechanism that has a simple structure and is difficult to break.
