13. The finger guard as defined in claim 1, wherein the auxiliary tongue is substantially more rigid than the elastic tongue.
14. The finger guard as defined in claim 1, wherein the supporting element includes a brush, the auxiliary tongue being between the brush and the elastic tongue and the brush, the auxiliary tongue and the elastic tongue facing the surface of the sliding door.
15. The finger guard as defined in claim 1, wherein the surface of the sliding door is uniformly smooth and flat.
16. A finger guard mounted in a gap between a sliding door of an elevator and a stop surface of a profiled edging strip, comprising:
means for urging a finger from the gap when the sliding door is closing;
the means for urging includes:
an elastic tongue extending from the profiled edging strip obliquely outward toward a surface of the sliding door; and
a supporting element disposed in the gap to keep the tongue clear of and at a distance from the surface of the sliding door;
whereby fingers are prevented from getting into the gap;
an auxiliary tongue substantially parallel to and spaced from the elastic tongue, the auxiliary tongue prevents the elastic tongue from turning too far toward the auxiliary tongue.
17. A finger guard mounted in a gap between a sliding door of an elevator and the stop surface of a profiled edging strip comprising:
means for urging a finger from the gap when the sliding door is closing; the means for urging includes:
an elastic tongue extending from the profiled edging strip obliquely outward toward a surface of the sliding door; and
a supporting element disposed in the gap to keep the tongue clear of and at a distance from the surface of the sliding door;
whereby fingers are prevented from getting into the gap;
an auxiliary tongue between the elastic tongue and the supporting element, the auxiliary tongue prevents the elastic tongue from turning too far toward the auxiliary tongue.
18. The finger guard as defined in claim 17, wherein the auxiliary tongue is substantially more rigid than the elastic tongue.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A cutting torch assembly, comprising:
a torch body having a distal end and an upstream end;
a torch head coupled to said distal end of said torch body;
a torch handle coupled to said upstream end of said torch body, said torch handle having an outer casing; and
a rotatable collar secured to said outer casing of said torch handle,
wherein said outer casing has a first retaining structure positioned at an upstream end of said rotatable collar, and a second retaining structure positioned at a downstream end of said rotatable collar,
wherein said torch handle can rotate relative to said rotatable collar, and
wherein no structure is positioned between an inner surface of said rotatable collar and an outer surface of said outer casing of said torch handle.
2. The torch assembly of claim 1, wherein each of said first and second retaining structures are comprised of a groove in the surface of said outer casing and a ring structure which is partially embedded in said groove such that said rotatable collar is positioned between each of said rings.
3. The torch assembly of claim 1, wherein said rotating collar can rotate 360 degrees relative to said outer casing.
4. The torch assembly of claim 1, wherein a gap between an inner surface of said rotatable collar and said outer casing has a maximum distance in the range of 0.0005 to 0.002 inches.
5. The torch assembly of claim 1, wherein said outer casing has a plurality of pairs of corresponding grooves which are spaced a predetermined distance from each other, where each of said respective pairs of grooves are spaced from each other by a distance to accommodate said rotatable collar and use a retaining structure in each of said grooves to secure said rotatable collar in a fixed position on said outer casing, and
wherein each retaining structure is removable to allow for the changing of the position of said rotatable collar along a length of said outer casing.
6. A torch handle assembly for a cutting torch, comprising:
a torch handle body having an outer casing; and
a rotatable collar secured to said outer casing of said torch handle body,
wherein said outer casing has a first retaining structure positioned at an upstream end of said rotatable collar, and a second retaining structure positioned at a downstream end of said rotatable collar,
wherein said torch handle can rotate relative to said rotatable collar, and
wherein no structure is positioned between an inner surface of said rotatable collar and an outer surface of said outer casing of said torch handle.
7. The torch assembly of claim 6, wherein each of said first and second retaining structures are comprised of a groove in the surface of said outer casing and a ring structure which is partially embedded in said groove such that said rotatable collar is positioned between each of said rings.
8. The torch assembly of claim 6, wherein said rotating collar can rotate 360 degrees relative to said outer casing.
9. The torch assembly of claim 6, wherein a gap between an inner surface of said rotatable collar and said outer casing has a maximum distance in the range of 0.0005 to 0.002 inches.
10. The torch assembly of claim 6, wherein said outer casing has a plurality of pairs of corresponding grooves which are spaced a predetermined distance from each other, where each of said respective pairs of grooves are spaced from each other by a distance to accommodate said rotatable collar and use a retaining structure in each of said grooves to secure said rotatable collar in a fixed position on said outer casing, and
wherein each retaining structure is removable to allow for the changing of the position of said rotatable collar along a length of said outer casing.
