Swimming and life saving device

A swimming device, comprising at least one floatation disk made of floatation material, an arm passage opening in said disk, said disk having a given diameter and a thickness which is small relative to said given diameter, said arm passage opening having a diameter smaller than an arm diameter at the location where the device is held on an arm in use, said device further comprising an elastic edge zone (4) surrounding said arm passage opening, said elastic edge zone (4) permitting the passage of an arm through said arm passage opening while also properly holding the device to an arm in a form-locking manner, said device further comprising attachment means for attaching a floatation disk to another similar floatation disk, said elastic edge zone (4), said attachment means, and said floatation disk being all made of suitable floatation material.

A swimming device, comprising at least one floatation disk made throughout its disk volume of floatation material for permanently maintaining its buoyancy independently of any inflation, an arm passage opening in said disk, said disk having a given diameter and a given thickness which is small relative to said given diameter, said arm passage opening having a diameter smaller than an arm diameter at the location where the device is held on an arm in use, said device further comprising an elastic edge zone (4) made of elastic foam material and surrounding said arm passage opening in said floatation disk, said elastic foam material of said edge zone (4) having an elasticity which is sufficient for permitting pushing a hand and an arm through said arm passage opening and for surrounding a user's arm in a form-locking manner, for properly holding the device on an arm by said form-locking during use.
