Abstract
Abstract A security device to prevent the unauthorized removal of sliding windows and doors from the frame structures in which they are slidably supported. The device is defined by a security clip having a substantially flat wall forming a mainstay and a spring-tension-jaw member integrally formed along the lower edge thereof. The security clip is arranged to be force-fitted over the depending flange of the frame structure, whereby the clip is held in a predetermined position relative to the sliding window or door. In order to prevent upward lifting of the window or door, the wall mainstay is formed having an inwardly bent, abutment lip for engagement with the window when raised from the lower frame-structure track. Ears are formed at the opposite ends of the abutment lip for engagement with the depending flange so as to reinforce and increase the strength and resistance of the abutment lip. A spacer bar is adapted to be positioned on the abutment-lip member to accommodate the various sizes of windows or doors.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
233 words
A security device to prevent removal of sliding windows and doors which are slidably mounted within a channeled frame structure, wherein the device comprises: a security clip adapted to be removably attached to a depending flange of said channeled frame structure; said security clip formed having a mainstay-wall member which projects upwardly into a channel of the frame structure adjacent the inner side of said depending flange; a spring-tension-engaging means formed longitudinally along the lower portion of said mainstay-wall member, whereby said device is forceably retained within said channel, said spring-tension-engaging means comprising a jaw member formed in a substantially S-shaped configuration, whereby said depending flange of said frame structure is forceably received between said mainstay member and said jaw member; an inwardly projecting, abutment-lip member formed longitudinally along the upper portion of said mainstay-wall member so as to be engaged by said window or door, when raised upwardly within said channeled frame structure, to limit the movement thereof; and an angularly disposed ear member formed on opposite ends of said abutment-lip member to engage said depending flange of said channel, when said lip is engaged by said window or door; and a space-control means mounted to said abutment lip to accommodate for the different spaces established between various windows or doors and their associated frame structures, so as to control the upward movement of said windows or doors within said frame structures.
Claim 2
Dependent Claim
233 words
A security device to prevent removal of sliding windows and doors which are slidably mounted within a channeled frame structure, wherein the device comprises: a security clip adapted to be removably attached to a depending flange of said channeled frame structure; said security clip formed having a mainstay-wall member which projects upwardly into a channel of the frame structure adjacent the inner side of said depending flange; a spring-tension-engaging means formed longitudinally along the lower portion of said mainstay-wall member, whereby said device is forceably retained within said channel, said spring-tension-engaging means comprising a jaw member formed in a substantially S-shaped configuration, whereby said depending flange of said frame structure is forceably received between said mainstay member and said jaw member; an inwardly projecting, abutment-lip member formed longitudinally along the upper portion of said mainstay-wall member so as to be engaged by said window or door, when raised upwardly within said channeled frame structure, to limit the movement thereof; and an angularly disposed ear member formed on opposite ends of said abutment-lip member to engage said depending flange of said channel, when said lip is engaged by said window or door; and a space-control means mounted to said abutment lip to accommodate for the different spaces established between various windows or doors and their associated frame structures, so as to control the upward movement of said windows or doors within said frame structures.
Claim 3
Dependent Claim
33 words
A security device as recited in claim 1, wherein said space-control means comprises an elongated spacer bar having a longitudinal slot formed therein, said slot being formed to receive said abutment lip therein.
Claim 4
Dependent Claim
35 words
A security device as recited in claim 2, wherein said slot formed in said spacer bar is disposed to define a pair of abutment members, one abutment member being thicker than the other abuttment member.
Claim 5
Dependent Claim
28 words
A security device as recited in claim 3, wherein said abutment lip of said clip includes means to prevent lateral movement of said spacer bar along said lip.
Claim 6
Dependent Claim
47 words
A security device as recited in claim 4, wherein said means to prevent lateral movement of said spacer bar comprises a pair of crimp members formed in said outwardly projecting, abutment lip, said crimp members being spaced apart whereby said spacer bar is mounted and secured therebetween.
Claim 7
Dependent Claim
24 words
A security device as recited in claim 1, wherein said inwardly projecting, abutment-lip member includes means to prevent lateral movement of said spacer bar.
Claim 8
Dependent Claim
45 words
A security device as recited in claim 6, wherein said means to prevent lateral movement of said spacer bar comprises a pair of crimp members formed in said abutment lip, said crimp members being spaced apart whereby said spacer bar is mounted and secured therebetween.
Claim 9
Dependent Claim
53 words
A security device as recited in claim 7, wherein said spacer bar is formed having a first abutment member and a second abutment member, each of said abutment members being defined by a longitudinal slot formed in said spacer bar, said first abutment member having a different thickness than said second abutment member.
