  • Patent number: 7859425
    Abstract: The invention provides for exchanging a complete luminous unit (24) instead of exchanging the individual components such as a battery (64). For this purpose, at least one energy-saving light-emitting diode (56) as luminous means, a battery (64) and a magnetically actuable reed contact (66) serving as switching element are combined as luminous unit (24). The use of a cost-effective light-emitting diode (56) and a battery (64) formed in space-saving fashion in accordance with the low power demand of the light-emitting diode (56) permits a compact configuration of the luminous unit (24). The fact that the luminous unit (24) can be inserted into the floating body (22) as a unit and can be exchanged as a unit obviates a complicated battery change or change of luminous means entailing the risk of leaks.

  • Patent number: 6691384
    Abstract: A buckle for safety belts is provided, especially for the waist belt of a life preserver. The buckle has a tongue plate, the pins of which are insertable into a slot-shaped recess of a main body in which are displaceably disposed two securing elements, which cooperate with the pins for locking the buckle, and which are resiliently biased into the locking position.

  • Patent number: 5685455
    Abstract: To provide a device (100) for inflating a container or a floating body, more particularly a life jacket, with the aid of a cartridge filled with pressure gas, which device comprises a releasing mechanism being independent of a tablet and being easily ready for operation, allowing a flexible operation and permitting an easy adjustment of the delay time in the case of release, it is suggested that, in said releasing unit (11; 11a-c), said first means comprise a sensor (49, 60, 73) which transmits an electric signal and that said second means comprise an electrically controllable locking means which, in the operative state, holds said retaining element in the retaining position and releases the same in the case of release.

  • Patent number: 5562233
    Abstract: A device as provided for the inflation of a container or a floating body of an item of lifesaving equipment with compressed gas. A compressed gas container sealed with the aid of a diaphragm is provided which, within the region of the container neck, possesses an external thread that can be screwed into a receiving aperture in a housing which is provided with a corresponding internal thread. The gas content of the container is released by opening the diaphragm with the aid of an opening striker disposed in the housing, which can be moved against the diaphragm by a hand lever and/or by the force of a spring. An indicating part indicates the screwing-in state of the compressed gas container, i.e., whether the compressed gas container is screwed-in so far into the receiving aperture that reliable operation of the device is guaranteed.

  • Patent number: 5493900
    Abstract: In order to provide an indicator (100) for compressed air bottles (10;31;50) or such for indicating the falling below a certain level of a defined pressure in the compressed air bottle (10;31;50), which ensures that it becomes discernible in the simplest manner whether a compressed air bottle possesses the requisite pressure and which prevents that, by the measuring of the pressure, an error source of pressure drops is produced, it is proposed that at least a certain portion (23;36;52) of the wall of the compressed air bottle (10;31;50) is constructed in such a way that the same is flexible so that this wall portion, at different pressures, is subject to certain different deformations.

  • Patent number: 5429539
    Abstract: A device is provided for the inflation of a floating body of a life jacket with pressure gas from a pressure gas container sealed with a diaphragm. The pressure gas container is screwed into a receiving aperture of a housing bore in a housing, and the gas content of the pressure gas container is released by opening the diaphragm with the aid of an opening striker disposed in the housing, which, by means of a hand lever, can be moved against the diaphragm. The opening striker is retained in its initial position with the aid of a spring. The housing bore communicates with a branch duct, wherein a non-return valve is disposed, while the branch duct terminates within the region of a life jacket connecting piece for supplying the gas content of the pressure gas container to the floating body on the housing outer surface with a gas outlet orifice. The housing can be fabricated in a single manufacturing process and is of one-piece construction.

  • Patent number: 5413247
    Abstract: An inflating device, more particularly for life jackets, includes a cartridge filled with pressure gas, which possesses a neck sealed with a diaphragm, and a cutter which, in the event of a release, penetrates with a sharp or pointed bottom portion the membrane on the cartridge. A releasing means, in the event of a release, acts upon the cutter with a force for penetrating the diaphragm. The diaphragm is distinguished by a simplified construction, which in particular permits the employment of a greatly simplified and very inexpensive cutter. It is proposed that the cutter be movably accommodated in a disposable part separated from the releasing means. The disposable part is rigidly connected with the cartridge and, together with the cartridge, can be detachably inserted into the releasing means.

  • Patent number: 5370567
    Abstract: A device (100) is provided for inflating, more particularly, a container or a floating body of a piece of lifesaving equipment with pressure gas from a pressure gas container (11) sealed with a diaphragm (14). The pressure gas container, within the area of a container neck (12), has an external thread (13) which can be screwed into a receiving aperture (15) in a housing (10). The gas content of the container (11) is released by opening the diaphragm (14) with the aid of an opening striker (24) disposed in the housing which may possibly be movable by means of a hand lever and by the force of a spring element against the diaphragm (14). The spring element in a pretensioned position, is retained with the aid of an automatic element (35) that loses its solidity in water. The pressure gas container (11) can be screwed into the receiving aperture (15) of the housing while simultaneously pretensioning the spring element.

  • Patent number: 5333756
    Abstract: A device is disclosed for the inflation of a container or a floating body of an item of lifesaving equipment with compressed gas. The gas content of a compressed gas container sealed with the aid of a diaphragm, is released by opening the diaphragm with an opening striker disposed in a housing. A lever drive comprising a swiveling lever possessing an intermediate member upon which a hand lever also acts, engages the opening striker to place the device reliably into operation. The swiveling lever is two-armed and swivelable about an axis of rotation that is integral with the housing. A first arm of the swiveling lever is supported upon a spring with its free end, and a second arm of the swiveling lever is supported on a housing stop. The second arm is supportable with its free end upon an automatic element. The intermediate member is two-armed and swivelable about an axis of rotation that is integral with the housing.
