Abstract
Abstract A track bolt assembly for use in a medical application for supporting medical utility items on a track in a medical wall. The track bolt assembly comprises a bolt having a nut threaded thereon, said bolt having an opening at one end and a spring inserted in the opening. A compression pin adjacent the spring is held in the opening in the bolt by virtue of a threaded plug. The threaded plug having opening through which the pin projects to allow depression of the spring within the bolt opening. A support panel is disposed between the nut and a retaining member, said support panel designed to hold a utility item for medical purposes. The retaining member designed to interact with a rectangular shaped elongated track assembly such that when the retaining member is parallel to the track assembly the entire track bolt assembly and utility item may be mounted onto the medical wall or removed from the medical wall. The retaining member designed to be rotated within the rectangular track assembly such that when so rotated and the nut tightened onto the support panel pressure is created causing the entire bolt assembly and utility item to remain in the position to which it has been tightened.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
227 words
Apparatus for moveably mounting a utility item along a track, said apparatus comprising: a bolt having an outer threaded portion at one end; an opening in said threaded end; a pin moveably mounted in said opening; a spring disposed between the pin and the bolt in said opening such that said spring constantly urges the pin out of the opening; means for maintaining said pin in said opening; a relatively planar support panel having an opening for receiving the bolt therethrough and means for mounting said utility item thereto; a retaining member threaded onto the outer threads of the bolt on one side of the support panel; a nut threaded onto the outer threads of the bolt on the other side of the support panel; a track having an inner area and an outer elongated opening joining the inner area; such that said retaining member is insertable at any point on the track through the elongate opening and turnable with said bolt by compressing the bolt and pin against an inner wall of the inner track area to engage the inner track area with the retaining member, such that when so engaged the nut may be tightened against the other end of the support panel thereby tightening the support panel to the track and causing the entire assembly to remain on the track at a predetermined location.
Claim 2
Dependent Claim
227 words
Apparatus for moveably mounting a utility item along a track, said apparatus comprising: a bolt having an outer threaded portion at one end; an opening in said threaded end; a pin moveably mounted in said opening; a spring disposed between the pin and the bolt in said opening such that said spring constantly urges the pin out of the opening; means for maintaining said pin in said opening; a relatively planar support panel having an opening for receiving the bolt therethrough and means for mounting said utility item thereto; a retaining member threaded onto the outer threads of the bolt on one side of the support panel; a nut threaded onto the outer threads of the bolt on the other side of the support panel; a track having an inner area and an outer elongated opening joining the inner area; such that said retaining member is insertable at any point on the track through the elongate opening and turnable with said bolt by compressing the bolt and pin against an inner wall of the inner track area to engage the inner track area with the retaining member, such that when so engaged the nut may be tightened against the other end of the support panel thereby tightening the support panel to the track and causing the entire assembly to remain on the track at a predetermined location.
Claim 3
Dependent Claim
75 words
The apparatus of claim 1 where the retaining member has a length and a width and where said length is greater than said width and where said elongate opening has a length and width, said length being greater than said width and where the width of the retaining member is less than the width of the elongate opening and where the length of the retaining member is greater than the width of the elongate opening.
Claim 4
Dependent Claim
44 words
The apparatus of claim 2 where the retaining member has a front planar shape in the form of a parallelogram and where the retaining member is joined to the outer threaded portion of the bolt such that turning the bolt turns the retaining member.
Claim 5
Dependent Claim
64 words
The apparatus of claim 2 where the retaining member has at each of its lengthwise opposite ends an abutment and where the inner track area has at its end adjacent the elongate opening means for engaging the abutments of the retaining member such that when said retaining member is turned in said inner track area the retaining member interlocks with the abutment engaging means.
Claim 6
Dependent Claim
34 words
The apparatus of claim 1 where the inner track area has a substantially rectangular cross-sectional shape and an inner wall and an outer wall and where said elongate opening is along the outer wall.
Claim 7
Dependent Claim
48 words
The apparatus of claim 5 where the pin in said bolt assembly may be compressed against the inner track wall to provide room for the retaining member to clear the outer wall of the track area when said retaining member is being turned in said inner track area.
Claim 8
Dependent Claim
52 words
The apparatus of claim 1 where the support panel has mounted thereon and spaced from the opening to receive the bolt assembly a guide protrusion to be received in said elongate opening thereby preventing the support panel from turning about the bolt when the assembly is engaged in the inner track area.
Claim 9
Dependent Claim
210 words
Apparatus for moveably mounting a utility item along a track, said apparatus comprising: a bolt having an outer threaded portion at one end; a relatively planar support panel having an opening for receiving the bolt therethrough and means for mounting said utility item thereto; a retaining member having a length and width threaded onto the outer threads of the bolt on one side of the support panel; a nut threaded onto the outer threads of the bolt on the other side of the support panel, said retaining member having at each of its lengthwise ends an abutment; a track having an inner area and an outer elongated opening joining the inner area; said inner track area having adjacent the outer elongated opening means for engaging the abutments of the retaining member such that said retaining member is insertable at any point on the track through the elongate opening and turnable with said bolt by compressing the bolt and to engage the inner track area at the abutment engaging means and such that when so engaged the nut may be tightened against the other end of the support panel thereby thightening the support panel to the track and causing the entire assembly to remain on the track at a predetermined location.
Claim 10
Dependent Claim
210 words
Apparatus for moveably mounting a utility item along a track, said apparatus comprising: a bolt having an outer threaded portion at one end; a relatively planar support panel having an opening for receiving the bolt therethrough and means for mounting said utility item thereto; a retaining member having a length and width threaded onto the outer threads of the bolt on one side of the support panel; a nut threaded onto the outer threads of the bolt on the other side of the support panel, said retaining member having at each of its lengthwise ends an abutment; a track having an inner area and an outer elongated opening joining the inner area; said inner track area having adjacent the outer elongated opening means for engaging the abutments of the retaining member such that said retaining member is insertable at any point on the track through the elongate opening and turnable with said bolt by compressing the bolt and to engage the inner track area at the abutment engaging means and such that when so engaged the nut may be tightened against the other end of the support panel thereby thightening the support panel to the track and causing the entire assembly to remain on the track at a predetermined location.
