Problems solved by technology

In this construction, the surface area over which the illuminated insert is capable of emitting light is rather small enough to effectively improve the possibility of viewing the level in low-light environments, and light is required in order to function
Additionally, the illuminated insert must be fabricated as a separate component and mounted to the level

Embodiment Construction

[0024] Before the exemplary embodiments of the invention are described in detail, it is to be understood that the invention is not limited to the details of construction and arrangement of parts described below or shown in the drawings. The invention is applicable to other embodiments, or of being practiced or carried out in various ways. It should also be understood that the phraseology and terminology used in the present application document are for the purpose of description only and should not be regarded as limiting the present invention.

[0025] 1 and 2 show a prior art box beam spirit level 10 having a three-sided opening 12 for receiving a closed vial 14 and an illuminated insert 16 under one side of the vial 14 . In low light conditions, light from the insert 16 is directed toward and through the vial 14, as schematically represented in FIG. 2 by the line 18 emanating upwardly from the insert 16. It can be seen that illuminating the vial 14 on only one side does not...

Abstract

A vial illumination feature for a tool, such as a level, is configured so as to emit light toward a vial when the tool is used in a darkened environment. The vial extends across an opening or a space defined by the tool, and one or more vial retainer members engage the ends of the vial to maintain the vial in position within the opening or space. The vial illumination feature is carried out by forming the one or more vial retaining members of a luminescent material. The luminescence of the one or more vial retaining members functions to absorb light when the tool is exposed to light, and to emit light toward the surfaces of the vial when the tool is in a darkened environment, to illuminate the vial and to enable the bubble of the vial to easily be viewed.

Description

technical field [0001] The present invention relates to spirit levels or other instruments that include bubble vials, and more particularly to instruments with vials that are surrounded by cover mechanisms to hold the vials in place on the instrument. Background technique [0002] Bubble vials are often combined with an instrument, such as a spirit level, to indicate the orientation of the instrument, eg, relative to a horizontal, vertical, or oblique plane. The vial contains a certain amount of fluid and contains an air bubble, and the user can determine the relative position of the instrument to the plane by viewing the position of the air bubble in the vial. [0003] Bubble vials consist of a tubular piece of transparent material that contains a volume of fluid inside. Typically, a vial is formed by injecting a fluid into a cylindrical member and then closing the open end of the cylindrical member with a cap to seal the interior of the cylindrical member and retain the f...
