Abstract
Disclosed is a wallet comprising two shell halves which are associated by a rigid spine to open and close the wallet, and containing a bunch of keys, anchored to the wallet. The wallet is biased to the open position by a pre tensioned skin which covers windows in the two shell halves. The skin allows temporary outward bulging by elasticity, and immediately springs back into the initial unloaded state at the time the bulging load is removed.
Claims20
Wallet, having four wallet boundary edges, comprising two shell elements which are associated by connection means at a spine of the wallet in such a manner that they are configured to pivot relative to one another around a pivot axis at the spine such that a first longitudinal boundary edge of the one shell element, is configured to move away from a corresponding first longitudinal boundary edge of the other shell element to move between an open and a closed position of the wallet by mutually pivoting of the shell elements, wherein a pre tensioned membrane material extends from the one shell element via the spine to the other shell element and biases the shell elements to pivot in the direction from the closed to the open position of the wallet, both if the wallet is in the open and closed position, and each shell element provides a main face of the wallet and further pivoting, due to the bias of the pre tensioned membrane material, of the shell elements in the direction from the closed to the open position of the wallet, beyond the open position of the wallet is blocked by a stop means of the wallet.
