Definitions

• a bowling lane provided with automated bowling equipment refers to a bowling lane having a string pinsetter for automatically clearing fallen pins on the pin deck and setting them back in their original positions for the next roll.
• Bowling lane pinsetters are divided into two groups, depending on how they operate.
• One group consists of string pinsetters wherein pins are connected to the pinsetters by strings, and, once a ball has knocked down some or all of the pins, the strings of all the pins are wound on the pinsetter spools to lift all the pins upwards off the pin deck, whereafter the leftover pins of the roll, identified by the machine and stabilized in the table, are reset onto the pin deck for a second roll. After the second roll, the entire pin rack is reset onto the pin deck.
• the other group consists of so-called free pinsetters with free-standing pins.
• the leftover pins are lifted up by the pinsetter, the pins knocked down by the ball are moved to the rear of the pinsetter by means dedicated thereto and the leftover pins are reset onto the pin deck for a second roll.
• any leftover or fallen pins are moved to the rear of the pinsetter and, therefrom, by means dedicated thereto, to the pinsetter organizing them into a rack and setting the rack onto the pin deck.
• Both these pin- setters include a ball return unit.
• the string pinsetters are significantly simpler in structure than the free pinsetters.
• the free pinsetters may comprise a number of components which is ten-fold compared to the string pinsetters. As automation was developed, the free pinsetters replaced the string pinsetters but now the situation is the opposite. Today, most of the machines used for entertainment and spare time bowling are string-operated. The free pinsetters have only maintained their position in competition bowling requiring a more accurate behavior of the falling pins.
• the invention is applicable to the above-described bowling lane structures associated with string pinsetters. The invention is suited for use with these pinsetters as they have a simpler structure than the free pinsetters. The arrangement and method according to the invention are suited for use with all string pinsetters, regardless their operating principle.
• the structural parts associated with a string-oper ated pin-setting apparatus include a backend with sidewalls, provided behind the pin deck, a pinsetter provided above the pin deck, pinsetter brackets and a ball return unit provided next to the backend.
• these structural parts are made of plywood and wood, and/or other similar materials, and fixed in place by means of screws, glue and nails. Should the structural parts include metal structures, they are joined by welding and/or riveting.
• the prior-art is presented in a product brochure of System-300 Group Oy.
• the sidewalls of the backend provided behind, i.e. as an extension of the pin deck, disclosed in the brochure, preferably are put together out of steel sheets, and, preferably, the pin deck is integrally fixed to an underlying base.
• the sidewalls provided on the sides of the pin deck have a wooden structure and are integrally fixed to the base, the backend and the bowling lane, through gutters.
• pinsetter brackets consisting of a variety of steel profiles, are attached to the upper edge of the sidewalls of the backend and the pin deck, the actual string pinsetter being attached onto them.
• the pinsetter comprises string spools, strings, pins connected to the strings, motion detectors, computer-assisted control units and any other components needed.
• a pin table having holes for stabilizing the pins is provided beneath the pinsetter.
• Said prior-art string-operated pin-setting apparatus is operated by fixedly installing pinset- ters, in a given position with respect to the pin deck, as a bowling lane comprising an auto mated bowling machine is set up.
• Bowling lanes comprising an automated bowling machine are structures fixedly installed in sports and spare-time facilities and applying different ways of fixing to fix the parts of the pinsetter together, including welding, screws etc. It is the fixed installation of the string-operated pin-setting apparatuses that involves most of the drawbacks of the prior art, by making very difficult and expensive to move the string- operated pin-setting apparatuses from one place to another. Therefore, they are not moved, but, at the same time, a possible application thereof is lost: setting up a bowling lane at a given place for a given period of time and moving it to its next location of use thereafter.
• This invention aims at providing an arrangement and method, hereafter briefly referred to “as the solution”, related to a string-operated pin-setting apparatus of a bowling lane pro vided with automated bowling equipment and avoiding, inter alia, the drawbacks encoun tered in the prior art.
• the solution according to the invention is characterized in what is set forth in the characterizing parts of claims 1 and 10.
• the major advantage of the invention is that the solution according to the invention allows a string-operated pin-setting apparatus, and the entire bowling lane along therewith, to be moved from one place to another by simple operations and inexpen sively.
• the string-operated pin-setting apparatus is the most complicated individual structure of a bowling lane, and also the most difficult one to move, but this invention makes it pos- sible to temporarily place a bowling lane provided with automated bowling equipment in almost any public facilities.
• the solution according to the invention allows a full-scale bowl ing lane equipped with a string-operated pin-setting apparatus to be inexpensively set up, for a given period of time, in an entertainment center, night club, bar, hotel, shopping mall or residential building, for example, and to be moved to a next location thereafter.
