Abstract
Abstract A self-inflating device for lifesaving equipment, in which the lifesaving equipment automatically inflates itself as soon as a piercing member forming part of the device is projected by a spring-urged shank into a closure diaphragm of a compressed air containing vessel. The spring-urged shank pertaining to a first housing section is prevented from hitting the piercing member by a preferably annular member arranged in a second housing member disengageably connected to the first housing member, as long as the device is not in the water but as soon as the device is in the water, the preferably annular member disintegrates and thereby permits the shank under the influence of the spring acting thereon to cause the piercing member to pierce the closure diaphragm for the compressed air containing vessel which then dispenses its content into the lifesaving equipment to be inflated. To ready the device for a new self-inflation, it is merely necessary to disengage the second housing section from the first housing section to allow a spring associated with the piercing member to lift the latter to its starting position, to replace the ring member and to connect a new pressure medium containing vessel and to again connect the first housing section to the second housing section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
237 words
An automatic inflating device for floating lifesaving devices, which includes housing means comprising a first section and a second section adapted to be threadedly connected to each other, said second section having an axial bore, striking means including piercing means and being reciprocably arranged in said axial bore of said second housing means section and being movable from a non-piercing position to a piercing position and vice versa, said second housing means section adjacent said piercing means comprising means for detachably connecting thereto a compressed gas containing cartridge with a closure diaphragm adapted to be pierced by said piercing means in said piercing position, a shank provided and reciprocably guided in said first housing means section in the axial direction thereof, spring washer means connected to said shank, spring means arranged around said shank between said spring washer means and that end portion of that first housing means section which is remote from said second housing means section, said spring means in non-piercing position of said striking means being tensioned to continuously urge said shank in the direction toward said striking means into said piercing position, lever means pivotally journalled in said second housing means section, and holding means adapted to disintegrate in water and in non-piercing position of said striking means holding said lever means partially between said shank and said striking means for preventing said shank from moving said piercing means into said piercing position.
Claim 2
Dependent Claim
237 words
An automatic inflating device for floating lifesaving devices, which includes housing means comprising a first section and a second section adapted to be threadedly connected to each other, said second section having an axial bore, striking means including piercing means and being reciprocably arranged in said axial bore of said second housing means section and being movable from a non-piercing position to a piercing position and vice versa, said second housing means section adjacent said piercing means comprising means for detachably connecting thereto a compressed gas containing cartridge with a closure diaphragm adapted to be pierced by said piercing means in said piercing position, a shank provided and reciprocably guided in said first housing means section in the axial direction thereof, spring washer means connected to said shank, spring means arranged around said shank between said spring washer means and that end portion of that first housing means section which is remote from said second housing means section, said spring means in non-piercing position of said striking means being tensioned to continuously urge said shank in the direction toward said striking means into said piercing position, lever means pivotally journalled in said second housing means section, and holding means adapted to disintegrate in water and in non-piercing position of said striking means holding said lever means partially between said shank and said striking means for preventing said shank from moving said piercing means into said piercing position.
Claim 3
Dependent Claim
23 words
A device according to claim 1, in which said lever means are pivotally supported by wall portions of said second housing means section.
Claim 4
Dependent Claim
42 words
A device according to claim 1, in which those sections of said first and second housing means sections which in assembled condition of said device are adjacent to each other are respectively provided with interfitting thread for threaded engagement with each other.
Claim 5
Dependent Claim
62 words
A device according to claim 1, in which said striking means includes a shank with a longitudinal slot, and in which a manually operable lever has one end portion pivotally connected to said second section of said housing means and extends through said slot and has its other end portion representing its free end portion projecting from said slot for manual actuation.
Claim 6
Dependent Claim
46 words
A device according to claim 4, in which said free end portion of said manually operable lever is so shaped as to engage the outside of said second housing means section when said spring means is tensioned and said striking means is in its non-piercing position.
Claim 7
Dependent Claim
19 words
A device according to claim 1, which includes means for non-detachably interconnecting said first and second housing means sections.
Claim 8
Dependent Claim
21 words
A device according to claim 1, in which said shank and said striking means are in axial alignment with each other.
Claim 9
Dependent Claim
28 words
A device according to claim 1, which includes a return spring associated with said piercing means for returning same to its non-piercing position following a piercing action thereof.
Claim 10
Dependent Claim
14 words
A device according to claim 1, in which said holding means consists of paper.
