Abstract
Abstract In a push-button lock for safety belts there is provided a base plate and a cover plate which is mounted on the base plate. For this mounting the base plate forms two upwardly bent marginal flanges at two opposite side margins and the cover plate forms an opening to be threaded on one of the flanges by such opening, as well as projections for engagement with said one flange from the outer side thereof and with the other marginal flange from the inner side thereof by lateral displacement of the cover plate. There is provided on the cover plate a manually operable blocking member which may be set against the inner side of said one flange for retaining the cover plate in a position in which it is connected with the base plate by the engagement between the projections and the flanges.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A push-button lock for safety belts, comprising a base plate having upwardly bent marginal flanges at two opposite side margins, an engagement member pivotally mounted to the base plate, spring means biassing the engagement member to locking position to engage a lock tongue inserted into the lock from one end thereof between the marginal flanges, a push button for operating the engagement member to a disengaged position against the spring bias, a cover plate which forms an opening and is threaded by this opening onto one of the marginal flanges, projections on the cover plate for engagement with said one flange from the outer side thereof and with the other marginal flange from the inner side thereof by lateral displacement of the cover plate, and a blocking member on the cover plate to be set against the inner side of said one flange for retaining the cover plate in a position in which the projections are engaged with the associated flanges, the cover plate maintaining the engagement member in operative position on the base plate.
Claim 2
Dependent Claim
175 words
A push-button lock for safety belts, comprising a base plate having upwardly bent marginal flanges at two opposite side margins, an engagement member pivotally mounted to the base plate, spring means biassing the engagement member to locking position to engage a lock tongue inserted into the lock from one end thereof between the marginal flanges, a push button for operating the engagement member to a disengaged position against the spring bias, a cover plate which forms an opening and is threaded by this opening onto one of the marginal flanges, projections on the cover plate for engagement with said one flange from the outer side thereof and with the other marginal flange from the inner side thereof by lateral displacement of the cover plate, and a blocking member on the cover plate to be set against the inner side of said one flange for retaining the cover plate in a position in which the projections are engaged with the associated flanges, the cover plate maintaining the engagement member in operative position on the base plate.
Claim 3
Dependent Claim
43 words
A lock as claimed in claim 1 wherein the projections are formed by marginal portions of the cover plate defining marginal recesses therein at the ends thereof, the opening forming a widened portion of one of the marginal recesses inwardly of the projections.
Claim 4
Dependent Claim
38 words
A lock as claimed in claim 2 wherein each of the marginal flanges is formed with a notch in the opposite end edges thereof to receive therein the projections formed by the marginal portions of the cover plate.
Claim 5
Dependent Claim
24 words
A lock as claimed in claim 1 wherein a spring biassing the engagement member is arranged on the upper side of the cover plate.
Claim 6
Dependent Claim
75 words
A lock as claimed in claim 4 wherein there is provided on the cover plate a bell crank one arm of which forms the blocking member and the other arm of which forms a seat for the spring biassing the engagement member this bell crank being pivoted about an axis transverse of the cover plate for setting the blocking member against said one marginal flange, the spring seat being simultaneously inserted under the push button.
Claim 7
Dependent Claim
58 words
A lock as claimed in claim 1 wherein tHe engagement member is pivoted by a tongue inserted into a slot in the base plate and is held by the spring bias in engagement position against the lower side of the cover plate, shoulders on the engagement member being in an operative position for engagement with the lock tongue.
Claim 8
Dependent Claim
55 words
A lock as claimed in claim 1 wherein there is displaceably guided in the base plate at least one abutment which is displaceable against the spring bias by the introduction of the lock tongue into the lock in order to throw out the lock tongue when the engagement member is operated towards the disengaged position.
Claim 9
Dependent Claim
65 words
A lock as claimed in claim 7 wherein the abutment is disposed at one end of a helical pressure spring which is received by a slot in the base plate and is retained therein by the cover plate at one side of the base plate and by a housing enclosing the base plate and the cover plate, at the other side of the base plate.
