Abstract

Abstract A leveling arrangement for a vehicle headlamp that includes a slot formed in the upper portion of the reflector member in which a spirit level member is located and combined with a spring clip which is fastened to the reflector member and to one end of the spirit level member and includes a leaf spring which continuously biases the other end of the spirit level member in one direction so that an adjustment screw threadably received by the spirit level member permits the aforementioned other end of the spirit level member to be raised or lowered for providing calibration of the spirit level member relative to the optical axis of the reflector member.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 192 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip having an end thereof fastened to said reflector member and to a first end of said spirit level member and having a portion thereof located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
Claim 2
Dependent Claim 192 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip having an end thereof fastened to said reflector member and to a first end of said spirit level member and having a portion thereof located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
Claim 3
Dependent Claim 208 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip comprising a T-shaped section connected to a pair of laterally spaced leaf spring members, the T-shaped section being fastened to said reflector member and to a first end of said spirit level member and having the leaf spring members located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end of and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
Claim 4
Dependent Claim 208 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip comprising a T-shaped section connected to a pair of laterally spaced leaf spring members, the T-shaped section being fastened to said reflector member and to a first end of said spirit level member and having the leaf spring members located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end of and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
Claim 5
Dependent Claim 225 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a T-shaped retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip having a T-shaped section including a cross arm and a depending leg one of which is fastened to said reflector member, a pair of tabs formed with said cross arm and connected to a first end of the spirit level member, a pair of leaf spring members extending outwardly from the cross arm and being located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end of and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
Claim 6
Dependent Claim 225 words
A leveling arrangement for a vehicle headlamp having a reflector member provided with a reflector cavity for projecting a light beam substantially parallel to an optical axis of the reflector cavity, a T-shaped retainer slot formed in an upper portion of the reflector member, said slot being defined by a bottom wall, a top wall and a pair of side walls, a spirit level member provided with a pair of outwardly extending legs located in said retainer slot, a spring clip having a T-shaped section including a cross arm and a depending leg one of which is fastened to said reflector member, a pair of tabs formed with said cross arm and connected to a first end of the spirit level member, a pair of leaf spring members extending outwardly from the cross arm and being located in said slot between said top wall and said legs for continuously biasing a second end of the spirit level member towards the bottom wall, and screw means threadably received by the spirit level member at the second end thereof and adapted to engage the bottom wall whereby rotation of said screw means causes pivoted adjustment of a position of the spirit level member about said first end of and thereby allows the spirit level member to be calibrated relative to the optical axis of the reflector cavity.
