Abstract
Abstract A key-operated keeper lock adapted for use in connection with a slide fastener and in which a lock housing carries a fixed anvil which underlies the slidable lacing element of the slide fastener, and a rotatable jaw member closely overlies said slidable lacing element in the locked condition of the lock. The jaw member is of the pop-up type, and when it is raised from a position of close proximity to the slidable lacing element, it may be swung to one side to expose the lacing element for manipulative purposes. An axial tumbler type lock assembly disposed alongside the jaw member operates through the medium of a detent ball to release the jaw member for pop-up purposes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
A keeper lock for securing the lacing element of a slide fastener, said lock comprising a lock housing presenting an anvil adapted to underlie said lacing element, said housing being formed with a pair of adjacent vertical sockets and an opening establishing communication therebetween, a movable jaw member having a stem received in one of said sockets and having a keeper flange thereon, said jaw member being capable of both angular turning and axial shifting movements so that it may assume a lowered and locked position with the keeper flange closely overlying the anvil and lacing element, an intermediate raised unlocked position with the keeper flange overlying but remote from the anvil, and a raised unlocked position with the keeper flange laterally removed from the anvil to expose the lacing element, spring means biasing said jaw member to its upper position, a key-operated lock assembly in the other socket and including a rotatable lock shaft, said stem having upper and lower shoulders thereon, and retractable detent means operable under the control of said lock shaft, projecting through said opening, and engageable with the upper shoulder to maintain the jaw member in its lowered and locked position and engageable with the lower shoulder to limit the upward movement of the jaw member.
Claim 2
Dependent Claim
211 words
A keeper lock for securing the lacing element of a slide fastener, said lock comprising a lock housing presenting an anvil adapted to underlie said lacing element, said housing being formed with a pair of adjacent vertical sockets and an opening establishing communication therebetween, a movable jaw member having a stem received in one of said sockets and having a keeper flange thereon, said jaw member being capable of both angular turning and axial shifting movements so that it may assume a lowered and locked position with the keeper flange closely overlying the anvil and lacing element, an intermediate raised unlocked position with the keeper flange overlying but remote from the anvil, and a raised unlocked position with the keeper flange laterally removed from the anvil to expose the lacing element, spring means biasing said jaw member to its upper position, a key-operated lock assembly in the other socket and including a rotatable lock shaft, said stem having upper and lower shoulders thereon, and retractable detent means operable under the control of said lock shaft, projecting through said opening, and engageable with the upper shoulder to maintain the jaw member in its lowered and locked position and engageable with the lower shoulder to limit the upward movement of the jaw member.
Claim 3
Dependent Claim
77 words
A keeper lock as set forth in claim 1 and wherein said detent means comprises a cam disk on said lock shaft and having a peripheral recess therein, and a detent ball movably disposed in said opening and engageable with the periphery of the disk, said detent ball, when disposed within said recess, projecting into the path of movement of said lower shoulder, and when withdrawn from said recess, projecting into the path of said upper shoulder.
Claim 4
Dependent Claim
38 words
A keeper lock as set forth in claim 2 and wherein each shoulder is in the form of a frusto-conical annulus and the lower shoulder presents a larger base diameter than the base diameter of the upper shoulder.
Claim 5
Dependent Claim
84 words
A keeper lock as set forth in claim 3 and wherein said lock housing is formed with an upper rim flange which surrounds said other opening and which is provided with a semi-circular relief area therein, the keeper flange is provided with a conformably shaped edge region, and the rim flange and keeper flange assume a substantially coplanar relationship when the movable jaw member is in its lowered and locked position and with said edge region projecting into and mating with the relief area.
Claim 6
Dependent Claim
54 words
A keeper lock as set forth in claim 4 and wherein said rim flange presents a first pair of abutment shoulders on opposite sides of said edge region and designed for engagement with said first pair of abutment shoulders to prevent rotation of the jaw member when the latter is in its lowered position.
Claim 7
Dependent Claim
70 words
A keeper lock as set forth in claim 5 and wherein said stem on the movable jaw member is comprised of two parts including a stem proper and a stem extension in the form of a locking cam on which said upper and lower frusto-conical shoulders are formed, and the locking stem is pivoted to the stem proper by a transverse pin which projects through the stem and its extension.
Claim 8
Dependent Claim
51 words
A keeper lock as set forth in claim 6 and wherein said locking cam is of stepped configuration and includes a lower enlarged cylindrical section, a reduced medial cylindrical section, and an upper further reduced cylindrical section, adjacent sections being provided with frusto-conical juncture regions which constitute said upwardly facing shoulders.
Claim 9
Dependent Claim
49 words
A keeper lock as set forth in claim 7 and wherein said stem on the jaw member is formed with a downwardly facing socket into which the upper reduced cylindrical section of the locking cam projects, and said transverse pin projects diametrically through said latter socket and cylindrical section.
