Background of the Invention
various forms of anchor members have been heretofore provided for the free end of a flexible tape strip. However, the substantially L-shaped configuration of the anchor member portion of the instant invention and its ability to embracingly engage the associated tape housing when the tape is not in use has not been used previously.
Examples of tape structures including free end anchor members including some of the structural features of the instant invention are disclosed in U.S. Pat. Nos. 1,029,767, 1,066,972, 2,466,405, 2,778,118, 3,281,493 and 3,473,235.
Brief Description of the Invention
The measuring tape anchor of the instant invention is constructed in a manner whereby it may be readily hooked around a corner of an object having one adjacent side to be measured and the anchor further includes structure whereby the associated flexible tape will be held tight against the side of a structure being measured and in a manner substantially eliminating any possibility of obliteration of the measuring indicia on the tape as a result of firm contact between the tape and the anchor.
Further, the anchor member portion is constructed so as to be generally L-shaped in configuration and positionable so as to embracingly engage the housing of the associated tape when the tape is not being used.
Also, the anchor member is pivotally attached to the free terminal end of the associated tape whereby the anchor member may be used in conjunction with variously shaped articles to be measured.
The main object of this invention is to provide a tape anchor for a flexible measuring tape to enable the free end of the measuring tape to be suitably anchored around a corner of an object having a side thereof adjacent the corner to be measured.
Another object of this invention, in accordance with the immediately preceding object, is to provide an anchor member including means by which considerable frictional engagement of the anchor with the object to be measured may be accomplished.
Yet another important object of this invention is to provide an anchor for a measuring tape constructed in a manner whereby the tape will be firmly pressed against an object being measured through the utilization of the anchor member.
A final object of this invention to be specifically enumerated herein is to provide a measuring tape anchor in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

Detailed Description of the Invention
Referring now more specifically to the drawings, the numeral 10 generally designates a conventional form of measuring tape rule construction including a cylindrical housing 12 having an entrance slot 13 formed in one peripheral portion. The housing 12 is hollow and has an elongated coiled flexible measuring tape 14 disposed therein. The measuring tape 14 includes a free end 16 to which a ring-type terminal end member 18 is secured. The terminal end member 18 is in the form of a generally rectangular ring including opposite longitudinal sides 20 and 22 and opposite end transverse portions 24 and 26. The ring-shaped terminal end member 18 has its transverse end member 24 pivotally attached to the free end 16 of the tape 14 by means of a pivot mount 28 and the terminal end member 18 may have an apertured flange member 30 pivotally attached to the end member 26 thereof.
The anchor member of the instant invention is referred to in general by the reference numeral 32 and includes a generally L-shaped bracket 34 including a pair of right-angularly disposed arms 36 and 38 joined at adjacent ends by means of an integral curved corner portion 40. The free end of the arm 36 includes a right-angularly disposed terminal end portion 42 whose free end is toothed as at 44. Further, the free end of the arm 38 is encircled by a resilient band 46 for a purpose to be hereinafter more fully set forth.
An abutment flange 48 is rigidly secured to the inner side of the base end of the arm 38 in any convenient manner and the flange 48 is provided with a smooth bore 50 therethrough registered with a second smooth bore 52 formed through the arm 38. A second flange in the form of a clamping flange 54 is provided inward of the abutment flange 48 and the clamping flange 54 also includes a smooth bore 56 formed therethrough. A threaded type fastener 58 is secured through the bores 50, 52 and 56 by means of a threaded nut 60 and the ring-shaped terminal end member 18 is clamped between the abutment flange 48 and the clamp flange 54.
With attention now invited more specifically to FIGS. 2 and 3 of the drawings it will be seen that the base end of the arm 36 has a slot 62 formed therethrough and a threaded fastener 64 is secured through the slot 62 by means of a nut 66. The fastener 64 also extends through the central aperture 68 formed in the flange member 30. Accordingly, the free end of the measuring tape 14 is secured to the anchor member 32 by means of the two fasteners 58 and 64.
In operation, if it is desired to measure one side 68 of a building structure 70, the anchor member 32 may be engaged with the corner 72 of the structure 70 with the arm 36 overlying the adjacent side 74 of the structure 70 and the teeth 44 frictionally engaged with the side 74. Then, the tape member 14 may be extended along the side 68 with the resilient sleeve 46 clamping the free end of the tape member 68 between the free end of the arm 38 and the side 68 of the structure 70. The resilient sleeve or sleeve member 46 prevents the measuring indicia 76 on the tape member 68 from being obliterated through continued use by the free end of the arm 38.
When the tape member 14 is substantially fully retracted within the housing 12, the L-shaped anchor member 32 may be positioned so as to snugly embrace approximately one-quarter of the external periphery of the housing 12 through which the entrance slot 13, is formed, see FIG. 4.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
