Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
225 words
In a tape drive window regulator having a tape slidably mounted in a fixed channel track, a drive block having teeth engaged with perforations in the tape, and a guide block slidably mounted on the track and also slidably engageable with the drive block for assembly therewith and wherein the guide block is drivingly connected to both the drive block and a window so as to effect opening and closing of the window as the tape is slid in opposite directions in the track, an improved drive connection arrangement between the drive and guide blocks comprising in combination: resilient drive means on one of the blocks for snapping into a position of drive engagement with the other block as the blocks are slidably engaged with each other during the assembly thereof to thereby effect a drive connection therebetween that is operable when the tape is slid in one direction in the track, rigid drive means on said one block for engaging with the other block to effect a drive connection therebetween that is operable when the tape is slid in the opposite direction in the track, and rigid interlock means on the blocks for engaging with each other to prevent disengagement of the drive connections provided by said resilient drive means and said rigid drive means and thereby maintain the blocks in their assembled condition.
Claim 2
Dependent Claim
225 words
In a tape drive window regulator having a tape slidably mounted in a fixed channel track, a drive block having teeth engaged with perforations in the tape, and a guide block slidably mounted on the track and also slidably engageable with the drive block for assembly therewith and wherein the guide block is drivingly connected to both the drive block and a window so as to effect opening and closing of the window as the tape is slid in opposite directions in the track, an improved drive connection arrangement between the drive and guide blocks comprising in combination: resilient drive means on one of the blocks for snapping into a position of drive engagement with the other block as the blocks are slidably engaged with each other during the assembly thereof to thereby effect a drive connection therebetween that is operable when the tape is slid in one direction in the track, rigid drive means on said one block for engaging with the other block to effect a drive connection therebetween that is operable when the tape is slid in the opposite direction in the track, and rigid interlock means on the blocks for engaging with each other to prevent disengagement of the drive connections provided by said resilient drive means and said rigid drive means and thereby maintain the blocks in their assembled condition.
Claim 3
Dependent Claim
224 words
In a tape drive window regulator having a tape slidably mounted in a fixed channel track, a drive block having teeth engaged with perforations in the tape, and a guide block slidably mounted on the track and also slidably engageable with the drive block for assembly therewith and wherein the guide block is drivingly connected to both the drive block and a window so as to effect opening and closing of the window as the tape is slid in opposite directions in the track, an improved drive connection arrangement between the drive and guide blocks comprising in combination: resilient drive means on the drive block for snapping into a position of drive engagement with the guide block as the blocks are slidably engaged with each other during the assembly thereof to thereby effect a drive connection therebetween that is operable when the tape is slid in one direction in the track, rigid drive means on the drive block for engaging with the guide block to effect a drive connection therebetween that is operable when the tape is slid in the opposite direction in the track, and rigid interlock means on the blocks for engaging with each other to prevent disengagement of the drive connections provided by said resilient drive means and said rigid drive means and thereby maintain the blocks in their assembled condition.
Claim 4
Dependent Claim
224 words
In a tape drive window regulator having a tape slidably mounted in a fixed channel track, a drive block having teeth engaged with perforations in the tape, and a guide block slidably mounted on the track and also slidably engageable with the drive block for assembly therewith and wherein the guide block is drivingly connected to both the drive block and a window so as to effect opening and closing of the window as the tape is slid in opposite directions in the track, an improved drive connection arrangement between the drive and guide blocks comprising in combination: resilient drive means on the drive block for snapping into a position of drive engagement with the guide block as the blocks are slidably engaged with each other during the assembly thereof to thereby effect a drive connection therebetween that is operable when the tape is slid in one direction in the track, rigid drive means on the drive block for engaging with the guide block to effect a drive connection therebetween that is operable when the tape is slid in the opposite direction in the track, and rigid interlock means on the blocks for engaging with each other to prevent disengagement of the drive connections provided by said resilient drive means and said rigid drive means and thereby maintain the blocks in their assembled condition.
Claim 5
Dependent Claim
234 words
In a tape drive window regulator having a tape slidably mounted in a fixed channel track, a drive block having teeth engaged with perforations in the tape, and a guide block slidably mounted on the track and also slidably engageable with the drive block for assembly therewith and wherein the guide block is drivingly connected to both the drive block and a window so as to effect opening and closing of the window as the tape is slid in opposite directions in the track, an improved drive connection arrangement between the drive and guide blocks comprising in combination: a resilient arm integral with the drive block for snapping into a position of drive engagement with the guide block as the blocks are slidably engaged with each other during the assembly thereof to thereby effect a drive connection therebetween that is operable when the tape is slid in one direction in the track, a first rigid projection integral with the drive block for engaging with the guide block to effect a drive connection therebetween that is operable when the tape is slid in the opposite direction in the track, and a second rigid projection integral with and transverse to said first rigid projection for engaging with the drive block to prevent disengagement of the drive connections provided by said resilient arm and said first rigid projection and thereby maintain the blocks in their assembled condition.
