Patent CA-2133862-A1 (CA)
Title: Magnetic paper clamp and method of producing same
Inventor: KRAPF WALLACE A
IPC: B42F1/02
Filed: 1994-10-07
Abstract: The clamp comprises a strip of heat-settable plastic which has two spaced, parallel strip magnets secured on one surface thereof, and which is bent into generally U-shaped configuration, for example by directing a heat knife onto the plastic strip medially of the space between said magnets, while folding opposite ends of the strip toward each other until the two magnets are placed in registering engagement with each other. After the plastic strip has been folded it is cooled to heat set the radiused fold, which thereby helps to retain the clamp closed and the magnets in engagement with each other.

Abstract: A l'approche de l'hiver, il faut ranger sécuritairement sa bicyclette dans un endroit qui la protègera des intempéries. Pour ce faire, l'idéal serait d'avoir une remise convenable. Hors, dans les grands centres urbains, l'espace est souvent restreint pour l'installation d'une remise. Même les locataires habitant les immeubles à logements sont contraints de louer des espaces de rangement qui sont souvent situés loin de chez-eux. Dans la présente invention, il s'agit d'un accessoire de rangement et de protection qui a la particularité de n'exiger qu'un minimum d'espace tout en préservant l'utilité d'une remise. Le pardessus pour vélo s'accroche à la plupart des balcons et permet à l'utilisateur de sécuriser, protéger et ranger à peu de frais une bicyclette.
