Abstract

Abstract A guide for properly aligning elongated fastening means which are used to join opposed parts separated by a substantial distance in an opening. A typical application for the invented screw guide is in a lock or latch assembly where the holding screws must generally pass through a substantial distance to join and engage opposed rosettes.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 185 words
In a combination, a device for guiding and aligning elongated fastening means extending through a substantial distance in an opening and a face plate comprising: a. a face plate having at least one hole therein adapted for receiving an elongated fastening means; b. a guide means mounted on one side of said face plate having at least one hollow elongated guide member of shorter length than said fastening means and a supporting means; c. said elongated guide member having at one end thereof a first opening and on the other end thereof a second opening of smaller cross section than said first opening, said first opening being positioned adjacent to and in substantial alignment with the hole in said face plate, said first opening having a cross section substantially larger than the cross section of said fastening means, said second opening having a cross section substantially identical to that of said fastening means to provide a relatively tight engagement between said fastening means and said second opening; and, d. said supporting means being integral with said elongated guide member and secured to said face plate.
Claim 2
Dependent Claim 185 words
In a combination, a device for guiding and aligning elongated fastening means extending through a substantial distance in an opening and a face plate comprising: a. a face plate having at least one hole therein adapted for receiving an elongated fastening means; b. a guide means mounted on one side of said face plate having at least one hollow elongated guide member of shorter length than said fastening means and a supporting means; c. said elongated guide member having at one end thereof a first opening and on the other end thereof a second opening of smaller cross section than said first opening, said first opening being positioned adjacent to and in substantial alignment with the hole in said face plate, said first opening having a cross section substantially larger than the cross section of said fastening means, said second opening having a cross section substantially identical to that of said fastening means to provide a relatively tight engagement between said fastening means and said second opening; and, d. said supporting means being integral with said elongated guide member and secured to said face plate.
Claim 3
Dependent Claim 48 words
The device of claim 1 in which said elongated guide member has a length and configuration adapted to allow said guide member to partially engage the walls of said opening thereby determining the position and alignment of the guide and face place combination with respect to said opening.
Claim 4
Dependent Claim 22 words
The combination of claim 1 in which said face plate is a rosette having a plurality of holes for fastening means therein.
Claim 5
Dependent Claim 20 words
The combination of claim 1 in which said guide means is secured to said face plate by mechanical fastening means.
Claim 6
Dependent Claim 19 words
The combination of claim 1 in which said guide means is secured to said face plate by an adhesive.
Claim 7
Dependent Claim 59 words
The combination of claim 3 in which said rosette has at least two spaced embossed holes for fastening means and said guide means contains at least two elongated guide members spaced on centerline corresponding to the centerline of the embossed holes on said rosette; whereby the edges of said embossed holes serve to engage and position said guide means.
Claim 8
Dependent Claim 17 words
The combination of claim 6 in which said elongated guide members are joined by said supporting means.
Claim 9
Dependent Claim 21 words
The combination of claim 7 in which said supporting means is a relatively flat member having rib means for providing rigidity.
Claim 10
Dependent Claim 206 words
In combination a device for guiding and aligning elongated fastening means extending through a substantial distance in an opening and a rosette comprising: a. a rosette having a given number of holes therein adapted for receiving a plurality of elongated fastening means; b. a guide means mounted on one side of said rosette having a given number of hollow frustoconical members of shorter length than said fastening means and a supporting means, the number of frustoconical members being equal to the number of holes in said rosette for receiving fastening means; c. each of said frUstoconical members having at one end thereof a first opening and at the other end a second opening of smaller cross section than said first opening, each of said first openings being positioned adjacent to and in substantial alignment with a hole in said rosette, each of said first openings having a cross section substantially larger than the cross section of said fastening means, each of said second openings having a cross section substantially identical to that of said fastening means to provide a relatively tight engagement between said fastening means and said second openings; and, d. said supporting means being integral with said frustoconical members and secured to said rosette.
Claim 11
Dependent Claim 206 words
In combination a device for guiding and aligning elongated fastening means extending through a substantial distance in an opening and a rosette comprising: a. a rosette having a given number of holes therein adapted for receiving a plurality of elongated fastening means; b. a guide means mounted on one side of said rosette having a given number of hollow frustoconical members of shorter length than said fastening means and a supporting means, the number of frustoconical members being equal to the number of holes in said rosette for receiving fastening means; c. each of said frUstoconical members having at one end thereof a first opening and at the other end a second opening of smaller cross section than said first opening, each of said first openings being positioned adjacent to and in substantial alignment with a hole in said rosette, each of said first openings having a cross section substantially larger than the cross section of said fastening means, each of said second openings having a cross section substantially identical to that of said fastening means to provide a relatively tight engagement between said fastening means and said second openings; and, d. said supporting means being integral with said frustoconical members and secured to said rosette.
Claim 12
Dependent Claim 16 words
The combination of claim 9 in which the frustoconical members have walls of substantially even thickness.
Claim 13
Dependent Claim 19 words
The combination of claim 9 in which said guide means is secured to said rosette by mechanical fastening means.
Claim 14
Dependent Claim 18 words
The combination of claim 9 in which said guide means is secured to said rosette by an adhesive.
Claim 15
Dependent Claim 16 words
The combination of claim 12 in which said frustoconical members are joined by said supporting means.
Claim 16
Dependent Claim 21 words
The combination of claim 13 in which said supporting means is a relatively flat member having rib means for providing ridigity.
Claim 17
Dependent Claim 46 words
The device of claim 9 in which said frustoconical members have a length and configuration adapted to allow said guide means to partially engage the walls of said opening thereby determining the position and alignment of the guide and rosette combination with respect to said opening.
