Abstract: A modular pool system including a plurality of pivotally connected panels disposed side end to side end defining an enclosed pool perimeter wall. The panels are pivotable with respect to each other to form a pool perimeter wall configuration. A pool liner is secured to the pool perimeter wall for retaining water within the pool perimeter wall.

Abstract: A base member for receiving the bottom of a wall of an above-ground pool comprising a plurality of rail members each having a first rail portion, a second rail portion and a hinge linking the rail portions, and an indexing device between the rail portions such that the rail portions can be locked in one of a plurality of orientations about the hinge, accommodating one of predetermined perimeters of the wall, whereby the member receives the bottom of the wall along the perimeter.

Abstract: An above ground swimming pool support structure is made up a plurality of posts, wherein each post is a blow-moulded unit having a base portion and top portion with a planar shoulder. A plurality of universal coping members also blow-moulded are interconnected end to end at selective angles, one end abutting the other at the planar shoulder of each post. A plurality of holes are provided at the opposite ends of the coping members. The connection of the adjacent coping members at the selective angles is maintained by pins inserted into aligned holes at the respective interconnected ends of the adjacent coping members, such that an endless top rail supported by the posts can be formed using the universal coping members for coping a flexible pool panel end to end of an above ground swimming pool in a preselected size. The advantages include the reduced manufacturing cost resulted from the limited number of moulds for manufacturing the moulded components and reduced labour required for erecting the pool.

Abstract: Disclosed is an apparatus for automatically teeing up golf balls having a hopper, a teeing up device and a control panel. The hopper is operatively connected to the teeing up device to supply golf balls to the automatic teeing up device. The teeing up device comprises a piston moving between a lowermost and an uppermost position within a guide cylinder below the ground level. Golf balls are selected and allowed on a tee one at the time. The tee is adjustable in height to simulate a tee off lie or a fairway lie. A detector is located under the tee to detect the presence of a golf ball on the tee to automatically tee up another golf ball when needed. The control panel activates, controls or deactivates the automatic teeing up device.

Abstract: A binding for a snowboard has a base, side members extending upwardly and rearwardly from the sides of the base, towards the back of the base, with an arcuate member joining the rear ends of the side members. Fastening means on one side member and on one side edge of the board at the front provide for attachment of one end of each of two straps. Fastening means on the other side member and on the other side edge serve for attachment of a locking bar which in turn connects the other end of each strap to the side member and base. Attachment means are provided in the base for attachment to a snowboard. A snowboard for use in conjunction with the binding has a forward attachment position which provides for attachment of a binding inclined in either direction as desired, that is forward and to the right or forward and to the left, as desired, at about 45.degree.. A rear attachment position provides for attachment of the binding transverse of the board.

Abstract: A utility knife comprises a hollow casing formed by a pair of elongated members pivotally mounted one to the other at one end of the casing. A blade passage is provided at another end of the casing. The elongated members are adapted for movement in substantially parallel planes between aligned closed functional and open diverging positions. The casing is provided with a mechanism adapted to carry and selectively position a blade. The utility knife further comprises a locking member pivotally mounted to one of the elongated members and adapted in a closed position thereof to secure the elongated members in their aligned closed position.
