Description

[Detailed Description of the Invention] This invention relates to a movable basket stand, and more specifically to a lifting mechanism for brake plates provided at the four corners of the cart.

Various types of mobile basket stands have been developed in which a frame holding a back board and a goal ring is attached to a cart so that it can be folded up and erected.

These movable basket stands are taken out of the equipment storage and run to a predetermined position on the court, the frame is erected or rolled out, and after the back board is set to use, the cart is moved to prevent the basket stand from moving. The brake plates installed at the four corners of the vehicle are lowered to touch the floor and are fixed.

However, since the brake plates provided at the four corners of the cart are raised and lowered one by one by rotating the handle, it takes time and effort to install and fold the basket stand, which is very inconvenient.

Therefore, the inventor of the present invention focused on the mechanism for folding and raising (including feeding out) the frame holding the back board in this type of mobile basket stand. A lifting mechanism was devised in which the brake plates of the car were raised and lowered at the same time.

That is, there are currently two types of frames in mobile basket stands, as shown in Figures 1 and 2. Also, a rotating shaft 11 provided at the base of the frame must be rotated.

Therefore, the present invention utilizes the rotation of this rotating shaft to raise and lower the brake plates installed at the four corners of the truck, and its basic structure is to have brake plates at the four corners of the vehicle that move up and down using racks and pinions. At the same time, the pinions at the four corners and the rotating shaft, which is the base point for folding and raising the frame, are connected by a rotation transmission means, and the brake plates at the four corners are simultaneously moved in and out in conjunction with the raising of the frame. There is something to be said.

In the present invention, as the rotation transmission means for transmitting the rotational motion of the rotary shaft to the pinion that moves the brake plate up and down, it is possible to adopt a transmission means consisting of a sprocket and a chain, or a transmission means consisting of a combination of a gear mechanism and a shaft. I can do it.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
The basket stand A is composed of a cart 1 and a frame 2 holding a backboard 3 and a goal ring 4, and the frame 2 is attached to the cart 1 so that it can be folded and raised.

The trolley 1 is equipped with casters 5 at the four corners of its lower surface so that it can run freely, and a brake plate 6 is attached near the casters 5 so as to be able to move up and down. , is performed in conjunction with the folding movement.

The frame body 2 includes a pair of left and right vertical rods 7, which are spaced apart from each other in the front and rear.
8 and a horizontally extending support rod 9 that is swingably connected to the upper ends of the vertical rods 7 and 8, and the lower end of the vertical rod 7 is a support shaft that is horizontally fixed across the left and right side walls of the truck 1. 10, and the lower end of the vertical rod 8 is integrally fixed to a rotating shaft 11, which is located rearward and lower than the supporting shaft 10 and is rotatably mounted horizontally. The intermediate portions of two actuating plates 12 having a dogleg-shaped side surface are integrally fixed to each other. The lower end of the operating plate 12 is connected by a shaft 14, and a rod 15' of a hydraulic cylinder 15 is connected to the shaft 14.
The tips are connected.

A backboard 3 is attached to the tip of the support rod 9 so as to be movable up and down, and is brought into use in conjunction with the activation of the vertical rods 7 and 8.

Note that the connection between the rear end of the support rod 9 and the vertical rod 8 has a double pipe structure, and by sliding the inner tube 8' connected to the support rod 9 side up and down by the rotation of the motor 16, the support rod 9 can be moved vertically. The height of the backboard 3 can be changed by swinging around the pivot point with the rod 7, and the height of the backboard 3 can be changed to the height for general competitions,
It can be adjusted to two types for junior high school competitions.

The mechanism that moves the brake plate 6 up and down in conjunction with the folding and raising of the frame 2 configured as described above is a mechanism that moves the brake plate 6 up and down in conjunction with the folding and raising of the frame 2.
Sprockets 17 of the rotation transmission means B are fixed to both left and right sides of the rotating shaft 11 which is the base point of the rising motion, and the brake plate 6 is integrally attached to the lower end of the rack shaft 18 by a screw structure and meshes with the rack shaft 18. A sprocket 20 is fixed to the shaft 19' of the pinion gear 19, a chain 21 is wound around the sphere 17 and the sphere 20, and the rotational motion of the rotating shaft 11 is transmitted to the pinion gear 19 via the chain 21. The rack shaft 18 is configured to move up and down.

In addition, the rotation is transmitted to the pinion gears 19 installed on the rear left and right sides of the truck 1 through the shaft 1 of the front pinion gear 19.
A sprocket 22 is fixed to the side opposite to the side to which the sprocket 20 of the sprocket 9' is fixed, and a chain 23 is wound around the sprocket 22 and the rear sprocket 20 for transmission.

With the above structure, when the frame body 2 is raised from the folded state to the use state, the rotational movement of the rotating shaft 11 at that time is transmitted through the transmission means consisting of the sprockets 17.20 and 22 and the chain 21.23. Rack shaft 1 provided at the four corners
8 and pinion gear 19, the rack shaft 18 moves downward, and the brake plates 6 at the four corners are simultaneously pressed against the floor surface, thereby fixing the truck 1.

The mobile basket stand of the present invention has the structure described in detail above, so that the brake plates installed at the four corners of the cart move down in conjunction with the upright movement of the frame and are crimped to the floor. The basket stand is fixed in a predetermined position, and when the frame is folded, the brake plate moves upward in conjunction with the movement, and when it is separated from the floor, the basket stand can move freely by the casters of the cart, making it movable. Become.

That is, since the brake plate is automatically operated in conjunction with the folding and raising of the frame, movement and installation can be performed more easily and quickly than with conventional basket stands.

Therefore, it is possible to provide a basket stand that can achieve the intended purpose.
