Dental safe-handling tool holder

Claim 2

A dental tool holder support comprising a support member having a groove across its upper surface for removably receiving a dental tool holder, said groove having along opposed sides undercut edges forming part of a dovetail joint, means along one side of the support member for mounting the support member on a bracket or like support surface, said mounting means comprising an exposed generally C-shaped edge surface configured to embrace a rod on the bracket.

Claim 3

A dental tool holder support as claimed in claim 1, further comprising means in the grooved surface for receiving biasing means on the holder.

Claim 4

A dental tool holder support as claimed in claim 1, further comprising a hole in the support member extending parallel to the groove.

Claim 5

A dental tool holder support as claimed in claim 2, wherein the means for receiving biasing means comprises a depression.

Claim 6

In combination: a bracket having a rod for mounting on a dental instrument panel; a support member removably mounted on the bracket rod and having an undercut groove along its upper surface; at least one cup-like dental tool holder having an open top and at its bottom a polygonal base removably mounted in the groove of the support member.

Claim 7

In combination: a bracket having a rod for mounting on a dental instrument panel; a support member removably mounted on the bracket rod and having an undercut groove along its upper surface; at least one cup-like dental tool holder having an open top and at its bottom a polygonal base removably mounted in the groove of the support member.

Claim 8

The combination of claim 5, wherein the support member has a recessed edge for embracing the bracket rod, and the groove is dovetailed.

Claim 9

The combination of claim 5, further comprising a rod slidingly mounted on the support member and having a circular end for receiving a cup.

Claim 10

A dental syringe holder comprising an elongated hollow member, means having a tapered threaded opening mounted inside the hollow member with the wide end of the taper facing one end of the hollow member, said hollow member having a polygonal base at its opposite end.

Claim 11

A dental syringe holder comprising an elongated hollow member, means having a tapered threaded opening mounted inside the hollow member with the wide end of the taper facing one end of the hollow member, said hollow member having a polygonal base at its opposite end.

Claim 12

The syringe holder of claim 8, wherein the tapered threaded opening comprises a metal spring located about midway in the hollow member.

Claim 13

The syringe holder of claim 9 for a syringe, wherein the syringe has a needle, and the tapered threaded opening is sized to grip a removable cover protecting the syringe needle.

Claim 14

The syringe holder of claim 9, wherein the polygonal base is hexagonal and is wider than the hollow member and is angled with respect to the hollow member.

Claim 15

In combination: a dental syringe holder comprising an elongated hollow member having a bottom and having a tapered threaded top opening with the wide end of the taper adjacent the top end of the hollow member, said hollow member having means for mounting the holder on a support surface; a dental syringe having a removable cover protecting a needle attached to the syringe, said cover having at least at one portion an outer diameter having a size between the inside diameters of the wide and narrow ends of the tapered opening, whereby when said syringe is positioned such that its removable cover is located in the tapered threaded opening of the hollow member, the removable cover can be gripped and held by the threads allowing removal and insertion of the needle, while attached to the syringe, from and into, respectively, its removable cover.

Claim 16

In combination: a dental syringe holder comprising an elongated hollow member having a bottom and having a tapered threaded top opening with the wide end of the taper adjacent the top end of the hollow member, said hollow member having means for mounting the holder on a support surface; a dental syringe having a removable cover protecting a needle attached to the syringe, said cover having at least at one portion an outer diameter having a size between the inside diameters of the wide and narrow ends of the tapered opening, whereby when said syringe is positioned such that its removable cover is located in the tapered threaded opening of the hollow member, the removable cover can be gripped and held by the threads allowing removal and insertion of the needle, while attached to the syringe, from and into, respectively, its removable cover.

Claim 17

The combination of claim 12, wherein the mounting means comprises at the hollow member bottom a hexagonal member angled with respect to the axis of symmetry of the tapered opening.
