In the present invention, a propulsion device 11 is provided for moving the mobile play equipment.

As shown in FIGS. 4 and 5, the propulsion device 11 includes a pair of insertion portions 12 fixed to both ends of the bottom frame 1, and its legs 13a are slidably inserted into the insertion portions 12. It is composed of an octopus-shaped handle 13 and a propulsion drive unit 14 attached to the lower end of the handle 13.

Details of the propulsion device 11 are shown in Figures 6 to 8 below.
This will be explained with reference to the figures.

As shown in FIG. 6, the insertion portion 12 includes a cylindrical body 15 slidably fitted to the leg 13a of the handle 13, and a bolt whose head is welded to the side surface of the cylindrical body 15. 16, a bearing plate 17 fixed to the bottom frame 1 and into which the tip of the bolt 16 is inserted; a collar 18 fitted onto the bolt 16 between the bearing plate 17 and the cylindrical body 15; The double nut 19 is inserted into the bearing plate 17 and fixes the cylindrical body 15 so as to be tiltable relative to the bearing plate 17. An annular stopper 20 is fitted into the leg 13a that is slidably inserted into the cylindrical body 15, and the stopper 20 is fixed to the leg 13a with a screw 20a. The stopper 20 abuts against the cylindrical body 15 to limit the sliding range of the handle 13.

Further, as shown in FIGS. 7 and 8, an angle plate 2 having an L-shaped cross section is attached to a bolt 21 whose head is welded to the lower end of the leg 13a of the handle 13.
2 is fixed with a nut 23. Also, the sled part 24
With the vertical portion 22a of the angle plate 22 sandwiched between the pair of plate-shaped bodies 24a erected on the upper surface, the bolt 25 is inserted and fixed with the nut 26, thereby causing the sled portion 2 to be attached to the angle plate 22.

Further, as shown in FIG. 9, the pawl 27 is pivotally supported at the tip of the sled portion 24 by a shaft 24b, and a stopper 28 is provided integrally with the pawl 27 at a substantially right angle. omitted for
Can be rotated within 90 degrees. The propulsion drive section 14 is composed of the above-mentioned angle plate 22, sled section 24, pawl 27, and the like.

Next, the operation of the mobile play equipment according to the present invention will be explained with reference to FIGS. 10 and 11. 10A, B, and C are side views showing different operating states of the propulsion device 11, and FIG. 11 is a sectional view taken along the line 10A, B, and C of FIG. 10.

Assume that the propulsion device 11 is now in a state where the leg portion 13a of the handle 13 is tilted slightly to the right with respect to the perpendicular, as shown in FIG. 10A.

From this state, when the operating part 13b of the handle 13 is tilted to the opposite side to the moving direction of the movable play equipment in the figure, that is, in the direction of arrow P, the leg part 13a is moved to the insertion part 1.
It rotates to the left around the second bolt 16.
At this time, the claw 27 is lying down, that is, the sled portion 24
Since the claws 27 are parallel to the ground G, the sled portion 24 moves on the ground G to the right in the figure. Also, the leg portion 13a
Since the cylindrical body 15 and the cylindrical body 15 are simply frictionally connected, when the leg 13a becomes vertical, the leg 13a will slide against the cylindrical body 15 and escape upward, so the weight of the moving play equipment can be absorbed by the handle 13. There is no need to support it, and the handle 13 can be moved easily. Note that at this time, the movable play equipment remains stationary.

As the handle 13 rotates in the direction of the arrow P, the leg portion 13a moves against the cylindrical body 15 due to the weight of the handle 13.
It tries to slide down inside, but the stopper 20 fixed to the leg 13a comes into contact with the cylindrical body 15.
The leg portion 13a does not fall below a certain position. Therefore, as shown in FIG. 9B, when the leg portion 13a leans to the left by more than a certain angle with respect to the perpendicular line, the distance between the bolt 16 and the ground G is kept constant by the diameter of the moving wheel 2. The sled portion 24 pivotally supported at the tip of the leg portion 13a is lifted upward. At this time, since the center of gravity of the sled portion 24 is selected to be on the opposite side to the direction of movement with respect to the bolt 25, that is, on the left side, the sled portion 24 is tilted downward to the left, and the right end of the sled portion 24 is lifted. Therefore, the pawl 27 rotates to the left in the figure due to its own weight, but since the pawl 27 is integrally provided with a stopper 28, the stopper 28 rotates due to its own weight.
8, the pawl 27 receives a further counterclockwise force and stops with the stopper 28 in contact with the sled portion 24. That is, the claw 27 is in an upright state.

In this state, as shown in FIG.
That is, when tilted in the direction of arrow Q, the claws 27 bite into the ground G and the sled section 24 is fixed to the ground G, so that the handle 13 is attached to the bolt 25 of the sled section 24.
The bottom frame 1, which is slidably connected to the handle 13 via the cylindrical body 15, rotates in the right direction with respect to the ground G, that is, the movement of the moving play equipment. will move in the direction. At the bottom of the bottom frame 1 there are moving wheels 2 as described above.
And since the guide wheels 3 are attached,
The moving play equipment will move along the rail 4.

At this time, the position of the cylindrical body 15 tends to rise as the handle 13 is tilted, but the leg portion 13a and the cylindrical body 15 are simply frictionally connected.
When the leg portion 13a becomes vertical, the handle 13 escapes upward relative to the cylindrical body 15, so the handle 1
3, it is not necessary to support the weight of the moving play equipment, and it is sufficient to apply only the force necessary to move the moving play equipment in the horizontal direction. Note that the vibration of the bottom frame 1 at this time can be absorbed by the shock absorber 5.

Next, when the handle 13 is tilted again in the direction of arrow P, the sled portion 24 moves to the right, so that the claw 2
7 collapses and returns to the state shown in FIG. 9A again.

Thereafter, by repeating this operation, that is, by gripping the handle 13 and operating it as if rowing a boat, the movable play equipment can be moved along the rail 4.

The movable play equipment can also be moved along the rail 4 by getting off the movable play equipment and directly pushing the rear part of the movable play equipment with your hand.

In the above-mentioned mobile play equipment, the entire mobile play equipment can be viewed as a ship, and the special gym 8 provided at the top of the mobile play equipment can be used as a deck or mast of the ship to climb up and down. By moving the mobile play equipment by moving the handle 13 back and forth, young children can play as if they were playing on a boat, and can develop creativity, attentiveness, judgment, etc. Furthermore, since the game can be played by a large number of people, cooperation can be developed through sharing of roles, cooperative operation of the handle 13, etc. Furthermore, according to the mobile play equipment of the present invention, older children and younger children can play together, allowing close contact between them. Furthermore, by pushing the moving play equipment itself, pushing and pulling the handles to move the moving play equipment, and climbing up and down the Young Gym 8, you will naturally strengthen your arm and leg strength and improve your agility. It can be fed. Furthermore, since the movable play equipment is moved along the rail 4, the range of movement can be limited to a range that is safe for young children to play with.
