Abstract
A spirit level having a sub-assembly on the body. The sub-assembly has a vial holder having two spaced pockets. A curved vial having two ends received in the pockets and resilient ribs having a curve matched to the vial and engaging the vial to hold the vial in an adjusted position. Each vial can be adjusted relative to a separate vial holder and each vial holder/vial sub-assembly can be independently adjusted and set relative to an appropriate edge of the level. The vial snaps into a fixed receptacle on either side of the vial holder. One side of the holder is curved to match the curve of the vial to insure that the vial is properly positioned. The underside of the vial holder may be relieved to increase flexibility to make it easier to snap the vial into place.
Claims23
A level comprising a first and a second vial holder;
- a curved vial for each said vial holder;
- first and second spaced pocket means on said first vial holder for receiving ends of said first curved vial;
- a first resilient means on said first vial holder urging said first curved vial into said first pocket means;
- second resilient means on said second vial holder urging said second vial into said second pocket;
- each said curved vials being adjustable in said vial holder relative to the other vial holder and adjustable relative to the appropriate edge of said level;
- each said vial holder having means engaging the vial on the other vial holder holding said vial in said pockets.
A level having a body and a window in said body;
- two identical vial holders supported in said window;
- a first glass plate in said window;
- said vial holders resting against said first glass plate;
- a second glass plate in said window resting against said vial holders;
- attaching means supporting said second glass plate with said vial holder between said first glass plate and said second glass plate;
- said two vial holders each holding a vial are supported, one on top of the other;
- each said vial holder has four corners;
- each said vial holder having a vial support means on said vial holder for adjusting said vial;
- and,
- two opposite corners of each said vial holders having means to attach said holder to said level.
A level comprising two sub-assemblies;
- each said sub assembly comprising a vial holder having two spaced plate-like support members each having an intermediate part;
- pocket means on each said support member;
- a curved vial having ends received in said pocket means;
- a rib;
- resilient means engaging said rib in said vial holder;
- said rib curved to match said curved vial and engaging said curved vial and prevent said vial from rotating;
- said resilient means engaging said vial end adapted to snap said ends of said vials into said pocket means.
A level comprising a holder, a resilient rib support on said holder;
- two spaced curved pocket means in said holder;
- a curved vial having ends and resilient means engaging said vial and adapted to snap said ends of said vial into said pocket;
- and,
- said curved vial being adjustable in said holder relative to an appropriate edge of said level.
A level having a body and a window in said body;
- two identical vial holders supported in said window;
- a first glass plate in paid window;
- said, vial holders resting against said first glass plate;
- a second glass plate in said window resting against said vial holders;
- attaching means supporting said second glass plate with said vial holders between said first glass plate and said second glass plate;
- a curved resilient means having a rib that has two ends;
- each said end having a curved shape to conform to a curvature of said vial whereby said vial can be adjusted relative to said vial holder and said curved rib prevents rotation of said vial.
