A chalk line device includes a housing and a chalk line stored in the housing. The chalk line terminates in a hook at one end and the hook is disposed outside of the housing. The housing may include a side wall with a depression formed therein that is shaped to receive the hook for storage. The depression has an edge that allows the hook to securely engage. The housing may also include a translucent window for allowing the user to check the level of chalk in the chalk line device. The translucent window forms at least a portion of a wall of the housing. The translucent window can be made, for example, of a plastic and can be integrally formed with the housing.

A construction tool has a tape measure. A handle is coupled to the tape measure. The handle allows a user of any size or shape hand to comfortably and easily use the tape measure.

A tape measure that incorporates a marking device for allowing an individual to measure and mark a wide variety of materials in a more efficient and economical manner, and for measuring and marking the beginning point of reference and the measured position point simultaneously. The tape measure has a housing, a coiled measuring tape, a tape tip, a chalk line, a chalk receptacle, a chalk line recharger, an activator, and an advancer. The chalk line is easily advanced and retracted for making marks at varying distances. The chalk is stored in a chalk storage receptacle that allows the chalk line to be re-chalked and is refillable for multiple uses. The activator allows the retractable chalk line to transfer a chalk substance from the chalk line to the surface to be measured and marked.

A chalk line end being comprised of two flat members (12a and 12b) set parallel at a slight distance from one another and bent and fused together along at least one shared edge to form a main body (10), containing a tear-shaped aperture (18) and towards one end a smaller aperture (22) which the chalk line (24) is tied through. A main tab formed by a section of at least one of said flat members bent essentially perpendicular to said main body. A blade (14), containing a similar tear-shaped aperture (18), is sandwiched between said two flat members of said main body, and pivotally attached (20) to said main body towards one end. A means for grasping (26) on said blade at the opposite end from the pivotal connection allows the user to grasp said blade between thumb and finger and rotate it out through a long open edge of said main body, until a fused section of said flat members stops it when the blade edge (30) is at an approximate ninety-degree angle to said main body. The user can then rotate the invention on the axis of said chalk line from its position in normal use, and hook it securely on a rounded or tapered edge engaging. A chalk line end of this type also allows the user to pop a line at an angle other than ninety-degrees off the edge of a sheet of material without the aid of a helper, nail or additional tools. The present invention, therefore, represents a significant and novel improvement over prior art chalk line ends.

One embodiment of the invention provides a chalk line device having a helical gear and an improved locking assembly. The locking assembly comprises a first lock member having a lock button. The locking assembly also comprises a second lock member including an opening to lockingly engage the first lock member and having a plurality of teeth at one end disposed adjacent one of the helical gears used in this embodiment. The second lock member engages with the helical gear in response to a movement of the lock button member.

The chalk line attachment clamp is a new approach to snapping a chalk line on a flat surface such as plywood, sheetrock and other construction materials. It holds the chalk line at the specific desired location and allows one person to make an accurate straight line to cut the flat surface material at any angle, thereby saving man-hours at the same time improving the accuracy of the saw cut to allow a better fitting of the parts being cut and improving the quality of the assembled project. The old method of requiring one worker at each end of the chalk line is no longer necessary. It will not be required to damage the material by driving a nail into the material to hold a chalk line in place.

A multi-function hand-operated tool that is compact in size and of light weight so as to be carried and used to perform a variety of different jobs by carpenters, painters, do-it-yourselfers, and the like. The tool includes a nail set to transmit a driving force to the head of a nail to cause the nail to be countersunk in a work surface. An open mouth which is sized to receive the cap on a bottle cooperates with a lip that applies a rotational force to remove the cap from the bottle. A nail extractor having a cavity in which to surround and capture the head of a nail transmits a pulling force to the nail head to cause the nail to be removed from a work surface. A channel having a flush-mounted magnet carries a nail to be positioned in upstanding alignment against a work surface so that the nail can be driven therein. A pair of spaced, outwardly projecting teeth are located between a lid and a can to pry the lid off the can. A chalk line is tied to the tool, and the teeth can be either staked in a work surface or located over and against an edge of the work surface so that a chalk mark can be made along the work surface. The teeth are spaced from one another so as to engage and lift a hinge pin from a hinge to which the pin is coupled.

A line-marking device (100) includes a chalk line (200) that is held in an elongated frame (170). A worker can position and align the device, then snap the line (200) using a manually operated trigger (650) to leave a mark on a surface (530), such as a wall or floor. An adjustable level device (115) on the frame (170) can be rotated to dial a desired angle for the line. The adjustable level device (115) may be provided in an angle setting device independently of the line-marking device. A laser device (125) may be carried at the tip (120) of (or elsewhere on) the frame (170) to allow the chalk line to be aligned with a reference mark (145). Respective markings (176, 177) on edge regions of rails (171, 174) of the frame (170) may indicate an angular setting of a guide bar (500), or, a protractor (810, 810a) may indicate-the angular setting. The guide bar (500) may be relocated facing away from the filament (200) and used as an angle finding device. A retractable tape measure (1500) carried by the device enables a worker to measure distances from the chalk line.

A chalk line is marked by attaching two hooks to a nail, and then extending a string a length from the nail. The hooks are attached to an apparatus that has multiple springs, such that there is a string attached to the rear of the apparatus while the hooks are attached to the front of the apparatus. When the string has been extended the desired length, the user then snaps the line to make a chalk line. Then, the pull on the string is released by the user, causing the two hooks to separate. When the two hooks separate, their connection to the nail is broken. The hooks and the apparatus associated with the hooks then is free to be reeled back to the user. The user does not have to return to the nail to remove the hooks and the associated apparatus.

A chalk line marking device includes a chalk line that is held in a storing, dispensing and retracting device. The device comprises a housing and an element for gripping the chalk line when it is extended from the dispensing device and lifting it from the workpiece surface at a point remote from the device. A spring mechanism causes the gripping element to suddenly snap back to its original position, when released, thereby causing the chalk line to leave a linear chalk mark on the workpiece surface. The device may also comprise a gripping element arranged within the housing that includes a plunger responsive to movement of the housing, for lifting and suddenly releasing the gripping element. A worker can extend the chalk line with one hand while holding the dispensing device in the other hand. The hand holding the dispensing device can actuate the gripping element with the thumb, for example, of that same hand while the other hand holds the extended end of the chalk line in position, thereby not requiring a third hand to snap the chalk line.

The motorized chalk box includes a chalk line reel having an internal ring gear. An electric motor drives a pinion gear, which engages the ring gear, thus resulting in a very compact assembly. The motor and gearing are sealed from the chalk dust reservoir, through which the chalk line passes. The housing comprises two components secured by a single screw to facilitate minor maintenance. A spring loaded, automatically releasing line clip extends from the distal end of the chalk line. The line clip includes a spring-loaded sleeve, which is biased against the anchor (screw, nail, etc.) when in place. Releasing the tension on the chalk line causes the sleeve to spring against the anchor, thus kicking the line clip away from the anchor. The chalk box may thus be operated using only one hand, greatly improving safety for workers in elevated environments.
