Problems solved by technology

However, in conventional chalk line devices, it is difficult to determine the level of quantity of chalk remaining in the reservoir.
However, in conventional chalk line devices, the clip is often left hanging and this may create the situation where the clip can get caught by some object or can be entangled with the line itself.

Embodiment Construction

[0018]Referring now to FIGS. 1-5 in detail, a chalk line device 10 is shown that includes a housing 12 having a chalk line port 14 and a chalk port 16. The housing 12 defines an exterior surface 18 and an interior space 20. The interior space 20 includes a chalk reservoir 22 in communication with the chalk port 16.

[0019]A movable door 24 (shown in FIGS. 1 and 3) is secured to the housing 12 over the chalk port 16 to selectively open and close the chalk port 16. Any suitable closure mechanism may be used including a hinged door, a sliding door or even a self-sealing access port. As seen in FIG. 5, a chalk line 26 is spooled around a chalk line support 28. The chalk line support 28 is rotatably mounted in the interior space 20 in the housing 12.

[0020]The chalk line 26 has one end 30 secured to the chalk line support 28 within the housing 12 and another end 32 provided with a hook 34 disposed outside of the housing 12. The chalk line 26 extends through the chalk line port 14.

Abstract

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.

Description

[0001]This application is a reissue application of U.S. Pat. No. 6,915,587, which issued on Jul. 12, 2005.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention pertains to chalk line devices, and more particularly, to chalk line devices with a housing having a viewing window and / or a housing having a structure for attaching an end of the chalk line.[0004]2. Discussion of Related Art[0005]Chalk line devices are widely employed to mark straight lines along a workpiece or work place. Generally, the chalk line device includes a housing or casing which defines a reservoir for storing chalk and stores an extendable line about a spool that is driven by a crank outside of the housing. Chalk line devices use a finely powdered chalk which is applied to the chalk line within the housing. The powdered chalk is usually colored brightly so as to allow the user to distinguish a mark line from a surface color of the workpiece. Generally, the housing is provided with ...
