Patent number: 6068230Abstract: A holding device for storing a hard-top including a belt system into which the hard-top can be placed in such manner that the weight of the hard-top is supported essentially entirely by the belt system. The belt system enables the hard-top to be fixed in the holding device and attached thereby to a wall or a ceiling of a room. A protective cover into which the belt system is sewn, can also be provided. The holding device is suitable for hard-tops with attachment pins as well as for hard-tops without attachment pins.Type: GrantFiled: July 8, 1998Date of Patent: May 30, 2000Inventor: Manfred Baecker

Patent number: 6056274Abstract: An apparatus for selectively raising, storing, and lowering a recreational water craft that includes a first cable. The first cable is attached at one end to a winch for selectively shortening or lengthening the first cable. The first cable is attached at the other end to a ring and the first cable passes through a first pulley. A proximal strap is releasably and adjustably attached to the boat and is connected to a second cable. The second cable is connected at one end to the proximal strap and at the other end to the ring. A distal strap is releasably and adjustably attached to the boat. The distal strap is connected to a third cable, with the third cable being attached at one end to the distal strap and at the other end to a size adjustment assembly. The size adjustment assembly is connected to the ring.Type: GrantFiled: June 2, 1998Date of Patent: May 2, 2000Inventors: Jane Eldredge Naas, Robert Lee Naas

Patent number: 6024425Abstract: A storage apparatus that includes a storage shelf having a plurality of horizontally and vertically arranged storage sections for storage of articles and a moving body for taking articles in and out of the storage shelf. Conventionally, since an article carrying in and out section for taking articles in and out of such storage apparatus is divided into working sections having substantially the same width as that of storage sections, a space for work is small and a work is made difficult and inefficient when the moving body is used to take articles out of the storage sections or articles are placed on the working sections. Therefore, a working space, which protrudes beyond the article carrying in and out section and is free of partitions is provided. With such arrangement, however, there is a problem that a storage apparatus is extended in a lengthwise direction.Type: GrantFiled: March 13, 1997Date of Patent: February 15, 2000Assignee: Daifuku Co., Ltd.Inventors: Masao Imai, Makoto Tanaka

Patent number: 5984275Abstract: A truck cap hoisting system includes a winch, at least one pulley, a pair of support channels, a pair of lifting strap assemblies, and a lifting line. The truck cap lifting system is preferably installed in a garage. The winch and a guide pulley are attached to a wall of the garage. The lift pulley is attached to a ceiling or an overhead beam. The lifting line is fastened to a lift ring and a reel of the winch. Each lifting strap assembly is threaded through one end of the pair of support channels. The truck cap is hoisted off the pick-up truck by first placing spacers between the truck and truck cap and sliding support channels in the gap. The same procedure is repeated for the opposite side. Four S-hooks extending from the pair of lifting assemblies are attached to the lift ring. The winch is then rotated until the truck cap is hoisted to a suitable height. The pair of support channels could be eliminated by forming at least four slots in the bottom of the truck cap sides.Type: GrantFiled: August 26, 1998Date of Patent: November 16, 1999Inventor: Glenn J.
