A method of producing a measuring tape may include providing a tape measure blade having a first end configured to extend from a housing and a second end configured to be wound on a reel assembly, defining a first non-critical region from the first end to a start of a critical region, defining a second non-critical region from the second end to an end of the critical region, and modifying a mass per unit length of a portion of the blade such that a mass per unit length of the first and second non-critical regions is less than a mass per unit length of the critical region.

A ratio tape measure has a case, a reeling unit, a ratio wheel unit, a decurling wheel, and a tape measure unit. The case has a reeling shaft, a ratio shaft, and a decurling shaft. The ratio wheel unit has a first perimeter wheel mounted around the ratio shaft and a second perimeter wheel mounted around the ratio shaft. The decurling wheel is rotatably mounted around the decurling shaft. The tape measure unit is wound around the reeling unit and the ratio wheel unit and has a first tape and a second tape. When the first perimeter wheel and the second perimeter wheel rotate, the first tape and the second tape can be pulled out at a fixed ratio, and a user can measure two lengths at one time.

A tool capable of creating and measuring circles and circular profiles of any size without the need for a pivoting center arm. Circle size can be selectively adjusted and held, and both the inside and outside of tool creates and measures circles of a near infinite number of size. The tool contains marking rules such as radius, diameter, arc length, circumference, sector area, area of a circle for any size circle, etc., obviating the need for calculating the same, and any or a combination of unit measure systems can be employed.

A Bluetooth-enabled tape measuring system, a cooperating mobile or desktop application, and a method for using same. A tape measure with retractable tape stores each measurement taken and transmits the measurement to a computing device for automatic recordation and association with the object of the measurement, which can be a user-input floor plan or the like. A software solution at the computing device is capable of planning necessary measurements, receiving transmitted measurements from the tape measure, and automatically associating received measurements with the user-input characteristics. The system may also direct the user to make certain measurements based on a user-stated project.

Disclosed is a measurement marking device for attachment onto a measuring tape or ruler; wherein the attached measurement marking device may slide/travel along the measuring tape or ruler, and set measurement(s) marking(s) onto the measured object at desired measurements/locations/sizes/lengths.

A combination tape measure and marker is provided. The combination tape measure and marker includes a measuring tape housing having a lateral portion, a lower portion, and a front portion. A track is connected to the lateral portion of the measuring tape housing. An arm is slidably disposed within the track. A tension member having an arcuate shape can slide the arm towards the lower portion when depressed. A cartridge is integrally attached to the front portion of the measuring tape housing. The arm extends through the cartridge. A marker is removably secured within the cartridge and is operationally attached to the arm. A spring is housed in the cartridge and provides a retracted and extended position for the marker. The marker is movably separately and independently from the measuring tape housing by selectively depressing the arm.

A device that includes or is attachable to a tape measure, that allows a user to take a measurement using the tape measure without requiring reference to measurement indicia. Such a device may include a base member, a housing on the base member including a slot for slidably receiving a tape of the tape measure when inserted through the slot of the housing during use, an elastomeric gripping layer positioned in the housing, positioned to contact a side of the tape when the tape is locked in a given position (e.g., given extension) during use, a movable pressure locking wedge positioned within the housing so that the tape is pinched between the wedge and another surface (the gripping layer is involved in such pinching), and a handle operable to move the wedge which allows selective locking of the tape between the wedge and other surface upon actuation of the handle.

A measurement device includes first and second measurement indicia. First indicia (e.g., on the tape) may include numerals regularly spaced to mark inches or other units of length (e.g., 1, 2, 3, etc,). Also included are second indicia, that are non-numeric (e.g., letters, such as A, B, C, etc.) where the second indicia are regularly spaced to mark fractions of inches or other units of length indicated by the first indicia. The second indicia are positioned between adjacent first indicia. For example, the letters (A, B, C, etc.) may he spaced every sixteenth or other fraction of an inch between the “1” and “2” (adjacent first indicia). Where sixteenths are used, the letters A-O are equally spaced, between the adjacent first indicia (e.g., between the “1”P′ and the “2”). The A-O may repeat between each integral number—between “1” and “2”, between “2” and “3” and so forth.

A tape measure marking system includes indicia along the length of a measuring tape positioned at regular distance intervals along the length of the measuring tape, with the indicia located at some regular repeating intervals along the tape being visually discernible relative to indicia at other regular repeating intervals along the tape to allow for easier visual identification of thicker intervals with respect to the other indicia.
