Pneuamtic gate of bowling game equipment

Abstract

A pneumatic gate unit of bowling apparatus is composed of a gate board able to be turned up and down around its horizontal rotary axle, a cylinder with a piston rod pivoted via pin to said gate board, a frame or wall for supporting the gate board, an optically (or magnetically) controlled open-close controller, and relative pneumatic and electric control systems. Its advantage is high speed to open or close gate.

Description

technical field [0001] The invention belongs to the field of cultural and sports facilities, and relates to a pneumatic goal in bowling equipment. Background technique [0002] There are three kinds of bowling gates in the prior art: a kind of is to belong to the part in the bowling ball (hereinafter referred to as ball) automatic ball return device, promptly is provided with a dial outside the ball gate, in operation, keeps beating left and right, generally controls two pins at the same time. When the ball is returned to the adjacent fairway, when the puck is shot to the left, the ball blocking the left fairway will not go out, while the ball on the right fairway will go out, and vice versa. The disadvantage is: when the balls in two adjacent fairways are almost going out , the plectrum must be repeatedly tapped left and right several times in order to use the time difference to release one of the balls out of its corresponding goal gate, and then release the other ball out...

Problems solved by technology

[0002] There are three kinds of bowling gates in the prior art: a kind of is to belong to the part in the bowling ball (hereinafter referred to as ball) automatic ball return device, promptly is provided with a dial outside the ball gate, in operation, keeps beating left and right, generally controls two pins at the same time. When the ball is returned to the adjacent fairway, when the puck is shot to the left, the ball blocking the left fairway will not go out, while the ball on the right fairway will go out, and vice versa. The disadvantage is: when the balls in two adjacent fairways are almost going out , the plectrum must be repeatedly tapped left and right several times in order to use the time difference to release one of the balls out of its corresponding goal gate, and then release the other ball out of its corresponding goal gate. Put the bottle out of the goal; another Chinese patent ZL98204485.2 discloses a purely mechanical goal. Its shortcoming is that the ball must be rotated at a high speed before it can touch the corresponding runner in the goal plate start switch control mechanism, thereby driving The interlocking mechanism opens the goal board and releases the ball out of the goal. Second, once individual bottles rush to the goal and the ball cannot approach the goal, the runners cannot or cannot be started in time to release the ball out of the goal. The third is that the structure is complex and the opening and closing speed of the goal board is slow. The fourth is that the interlocking of the two goal boards in two adjacent fairways is prone to problems. Sometimes both of them cannot be opened, resulting in the ball not being able to go out of the goal. A bowling automatic goal disclosed in patent ZL99119762·3 also has the disadvantages of complex structure, slow movement, easy failure and misoperation only releasing the bottle out of the goal.
