Description

[Detailed description of the device] (The purpose of the device) This device is designed to rotate the rope, which is taken as part of the physical education class for children or as one of the usual activities of children, and to make it into a loop. It aims to provide a device with a new structure for mechanically rotating a rope, which is a "horizontal rotating rope jump" in which children in a line jump so as not to get caught on the rope.

(Prior Art) As is often regarded as a phenomenon for children, children have recently decreased their physical activity.
One of the reasons for this is the fact that there is no provision of play tools that will appeal to children for that purpose. This would suggest that it is the responsibility of society to correctly understand the present consciousness of children, and then give it as a modern modification rather than a coercion in the same way as it used to be.

The only play tools provided for this purpose so far are the foot-operated devices that connect to recently released family computers, which are generally expensive and individually hand-held. On the other hand, it is difficult to make it cheap, but on the other hand, it is a situation where traditional playground equipment such as bamboo horse, rope skipping, yo-yo, etc. are offered simply by changing the material, and it is of interest to children today. Far from it, children are now obsessed with video games and wireless cars that do not use their bodies.

In order to deal with such a phenomenon, this device has been searching for something that should always be the subject of it in relation to ordinary children over a long period of time, and finally found the one that seems to correspond to it. Finally, the mechanization was successful, and the structure is as described in detail below.

(Structure of the Invention) As can be clearly understood from the embodiment representative of the present invention shown in the drawings, this horizontal rotary rope skipping device is provided with a motor at an appropriate height position of a column 1 vertically installed at the center of a leg 1. The mounting base 2 is mounted so that its height can be adjusted, while the motor 6 having the roller 61 mounted on the rotary shaft 62 is mounted on the motor mounting base 2 so that the rotary shaft 62 faces the strut 1. At the same time, the rotary plate 3 having the rope attachment portion 32 is rotatably mounted above the motor mount base 2 whose height is adjustable so as to be in contact with the roller 61 of the motor 6. The rope attachment portion 32 is formed by detachably attaching the rope 4 of an appropriate length.

As shown in the cross-sectional view of FIG. 2, the column 1 is a hollow column, the lower end of which is fitted to the central connecting portion 51 of the leg portion 5, which is assembled with a thumbscrew 52 or the like and can be freely disassembled. It is attached so as to support the motor mounting pedestal 2 and the rotary plate 3 which will be described later and to temporarily attach the covers 28, 37, 53, etc., and the transparent cover portion 71 is provided on the upper end thereof. It is convenient to attach the cap 7 that the user has and to appropriately incorporate various accessory devices 8 such as a blinker, a sound source, and a counter that increase interest in skipping rope using the space.

As shown in the plan view of FIG. 3 and the bottom view of FIG. 4, the motor mounting pedestal 2 has a fitting hole 21 for fitting into the support column 1, and the mounting edge 22 is attached to the support column 1. The height is adjusted by the thumbscrews 23 and 23 in accordance with the optimum screw holes 11 and 11 in the height selecting screw holes 11 and 11 formed on the side of the. .

Further, the motor mounting base 2 is cut out at a proper position outside thereof, and a fixing frame 25 for slidably fixing the motor 6 is attached to the rear surface of the position, while a groove portion 24 is formed on the front surface to form ball bearings 26, 26. ... should be placed.

As shown in the plan view of FIG. 5 and the bottom view of FIG. 6, the rotary plate 3 has a fitting hole 31 for the support post 1 in the center and supports the support post 1 via ball bearings 35, 35 .... In addition to being configured to freely rotate around, a plurality of rope attachment parts 32, 32 ... Are formed at appropriate places on the surface so as to be detachable, and a motor 6 to be described later is provided near the outer periphery of the back surface. The friction track 33 that contacts the roller 61 is formed.

In the figure, 34 is a notch formed in the friction track 33, 36 is a hammer for bell-vibration for rotational display which will be formed as required, and 38 is a balancer.

The rope 4 is a rope attachment portion 32 formed on the surface of the rotating plate 3.
On the other hand, as shown in the figure, only one piece is attached, or a plurality of pieces are attached at the same time depending on the difficulty level of jump rope, and a weight 42 made of rubber or plastics is formed at the tip. Is desirable.

Hereinafter, a preferred embodiment of the present invention will be described.

(Preferred Embodiment 1) First, the motor mounting pedestal 2 is a horizontal rotary jump rope device that is attached to the support column 1 so that the height position can be changed.

The structure for changing the height position is such that the screw holes 11 and 11 on the outside of the columns 1 formed at a predetermined pitch as in the illustrated embodiment.
.. is selectively used, and although not shown, a screw thread is formed on the outside of the column 1, and the attachment edge 22 of the motor mounting base 2 is screwed into the thread to move it up and down. Can be adjusted and the position can be fixed with a fixing pin or the like, and an appropriate structure can be adopted.

(Preferred Embodiment 2) Next, the motor 6 is a horizontal rotary rope jumping device in which its mounting position is changeably attached to the motor mounting base 2.

The change of the mounting position is to change the position where the roller 61 of the motor 6 comes into contact with the back surface of the rotating plate 3 and can be moved back and forth on a line passing through the center of the support column 1, for example, as shown in the illustrated example. The long hole 26 formed in the motor fixing frame 25 is used to appropriately move the motor 6 back and forth, and the thumbscrew 63 fixes the motor 6.

In FIG. 2, there is a drawing gap between the back surface of the rotary plate 3 and the roller 61, and between the back surface of the rotary plate 3 and the ball bearing 27. There is no gap, and the contact state is realized.

(Preferred Embodiment 3) This example is a horizontal rotary rope skipping device in which the rope 4 is attached to the rotary plate 3 via a guide rod 41.

In the illustrated embodiment, the guide rod 41 is interposed, but the guide rod 41 may be omitted and the rope 4 itself may be connected directly or via a connecting fitting or the like. Of course, there is no problem.

However, in the case where the guide rod 41 is not adopted, the rope 4 may be entangled with the support column 1 and the leg portion 5 at the beginning of rotation, so consideration should be given to them beforehand.

(Preferred Embodiment 4) The following example is an example of a horizontal rotary rope skipping device in which the motor mounting base 2 and the rotary plate 3 are protected by covers 28 and 37, respectively.

These covers 28 and 37 are attached to the motor mounting base 2
Must be configured so that the mounting position can also be changed according to the change in the position of the motor mounting base 2 of the embodiment. The structure in which the screw holes 11, 11 for changing the height position are shared is adopted, and the cover 37 on the rotating plate 3 side is detachably screwed to the upper column 1 of the vertically divided column 1. , The lower end of the strut 1 on the divided side is forcibly fitted into the vertical groove 12 of the dovetail section provided on the upper end outside of the lower strut 1, and the upper strut 1 is moved up and down, Although the attached cover 37 also has a structure in which it moves up and down,
Of course, this configuration is not limited to the embodiment, and it does not matter if the covers 28, 37 and the support 1 are formed in a screwing structure or in any other suitable structure. .

Note that the cover 53 attached to the leg portion 5 is different from the covers 28 and 37 described above, and it is not necessary to change the height position in particular, and although the nature is different from the covers 28 and 37, Due to the design of the entire device, a similar cover is used in the embodiment.

This cover 53 has a function of covering the transformer 9 for external power supply and the dry battery 91 arranged on the leg 5, and when the leg 5 itself is formed in a box shape. Needless to say, is unnecessary.

(Operation) In the horizontal rotary rope skip device of the present invention configured as described above, one or a plurality of ropes 4 are connected to the rope attaching portion 32 of the rotary plate 3, and the switch 93 is operated to activate the motor 6. When rotated, the roller 61 mounted on the rotation shaft 62
However, it starts rotating while coming into contact with the friction track 33 on the back surface of the rotary plate 3.

Then, the rotary plate 3 placed on the motor mounting base 2 via only the ball bearing 27 and the roller 61 naturally starts to rotate, and the rope 4 connected to the rotary plate 3 is started.
The children lined up so as to surround this device will also rotate in the horizontal direction because they also rotate to become substantially horizontal.
It jumps up in order according to when it comes to itself, and repeats the jump rope until it gets caught on the rope 4.

In this skipping rope, as mentioned above, many children can be used as a group game in which they compete in a loop without jumping on the rope 4 until the end.
As an individual game, there is also a method of playing by jumping over the rope 4 in the direction opposite to the direction of rotation of the rope 4 that comes around, and competing to see how far ahead you can proceed without getting caught on the rope 4. Rope 4 automatically and at a constant speed in either case
It is possible to turn the to a substantially horizontal state.

(Effect) Since the horizontal rotary rope skipping device of the present invention as described above can rotate the rope 4 mechanically first of all, the rope 4 is sacrificed by one of the children playing for that purpose. The problem of having to take on the role of turning is solved, and it has the great feature that everyone can play in an equal relationship.

Moreover, the configuration in which the rope 4 is rotated is the same as the roller 61 and the rotating plate 3.
Since it is an extremely simple thing that is realized only by the relationship with, it does not become complicated and expensive like gear conduction and belt conduction, but even if someone gets caught, it is complicated like a ratchet mechanism. Since the structure that allows the rotating plate 3 to idle around on the roller 61 without any special mechanism is realized, it not only harms children, but also the device itself is not overly stressed. ,
The most important safety advantage of this type of device is that it does not cause any risk of the device tipping over, causing harm or damage.

On the other hand, since the device of the present invention has a structure in which the height position of the motor mounting base 2 can be changed, the motor mounting base 2 can be adjusted according to the age and height of the target children or the difficulty of the game. It is possible to easily set it again at the appropriate height position and change the jumping height, so that the content of the play can be enriched to the extent that it becomes a device that further arouses the interest of children. .

Further, in the case of a device in which the mounting position of the motor 6 is changeable, not only the above-mentioned jump-bounce height can be changed but also the rotation speed of the rotary plate 3 can be changed, and the jump-bounce interval can be changed. It is also possible to change, and the contents of play can be further changed. Further, when the rope 4 of this device is provided via the guide rod 41, the rope 4 can be turned at the beginning or end of the rotation. Is prop 1
Since it is possible to completely eliminate the concern that it becomes difficult to operate because it is entangled with the legs 5 or the like, it will be very advantageous for widespread use without any difficulty even if this device is operated only by children. .

In addition, in the case where the covers 28 and 37 are combined with the motor mounting base 2 and the rotary plate 3, not only the effect that the operating portion is simply protected but also the appearance is advantageous, The diffusion effect will be further enhanced.

As described above, the horizontal rope skipping device of the present invention is very simple in construction, not only easy to manufacture and inexpensive to provide, but also very advantageous in handling and operation. Since it is a safe and easy to use jump rope device, it has the potential to be well accepted by recent children who are losing interest in playing with their bodies. It is expected that it will be used by many children and will be a valuable device to enjoy the enjoyment of physical play.
