Abstract
Abstract A securing structure is used in securing a plurality of pipes of comparatively small diameter together. With each pipe having a flat surface portion in a straight section thereo, a bracket body is injection-molded from thermoplastic resin such that the flat surface portion and its vicinity of each pipe are embedded in the bracket body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A pipe securing structure comprising: a plurality of elongated pipes, each said pipe having a longitudinally extending securing section with opposed longitudinal ends and a selected cross-sectional configuration, each said pipe further including portions extending longitudinally from the respective opposed ends of the securing section and defining cross-sectional configurations different from the securing section; and a bracket body unitarily injection molded from a thermoplastic resin such that the thermoplastic resin of the bracket body surrounds and engages the entire securing section of each said pipe and regions of each said pipe adjacent the opposed ends of the respective securing sections, whereby the surrounding engagement of the thermoplastic resin with the securing sections and regions of each said pipe adjacent the respective securing sections prevents relative movement between the pipe and the bracket body.
Claim 2
Dependent Claim
133 words
A pipe securing structure comprising: a plurality of elongated pipes, each said pipe having a longitudinally extending securing section with opposed longitudinal ends and a selected cross-sectional configuration, each said pipe further including portions extending longitudinally from the respective opposed ends of the securing section and defining cross-sectional configurations different from the securing section; and a bracket body unitarily injection molded from a thermoplastic resin such that the thermoplastic resin of the bracket body surrounds and engages the entire securing section of each said pipe and regions of each said pipe adjacent the opposed ends of the respective securing sections, whereby the surrounding engagement of the thermoplastic resin with the securing sections and regions of each said pipe adjacent the respective securing sections prevents relative movement between the pipe and the bracket body.
Claim 3
Dependent Claim
29 words
A securing structure according to claim 1, wherein the bracket body is molded from a thermoplastic resin selected from the group consisting of nylon, polyethylene, polypropylene, polyacetal, and ABS.
Claim 4
Dependent Claim
15 words
A securing structure according to claim 1 wherein each said pipe is made of metal.
Claim 5
Dependent Claim
15 words
A securing structure as in claim 1, wherein each said pipe is made of resin.
Claim 6
Dependent Claim
24 words
A securing structure as in claim 1, wherein the portions of each said pipe adjacent the securing section are of substantially circular cross-sectional configuration.
Claim 7
Dependent Claim
24 words
A securing structure as in claim 1, wherein the securing section of each said pipe is characterized by at least one flat surface portion.
Claim 8
Dependent Claim
17 words
A securing structure according to 6 wherein each said pipe has a pair of flat surface portions.
Claim 9
Dependent Claim
17 words
A securing structure according to 6 wherein each said pipe has a pair of flat surface portions.
Claim 10
Dependent Claim
137 words
A pipe securing structure comprising: a plurality of elongated pipes, each said pipe being unitarily formed and having a longitudinally extending securing section intermediate the length of each respective pipe, the securing section including at least one flat surface portion, each said pipe being of substantially circular cross-section adjacent each longitudinal end of the securing section; and a bracket body unitarily injected molded from a thermoplastic resin, such that the thermoplastic resin of the bracket body surrounds and engages the entire securing section of each said pipe and regions of each said pipe adjacent to the respective securing sections, whereby the surrounding engagement of the thermoplastic resin with the securing sections and regions of each said pipe adjacent to the securing sections prevents relative longitudinal and rotational movement of each said pipe relative to the bracket body.
Claim 11
Dependent Claim
137 words
A pipe securing structure comprising: a plurality of elongated pipes, each said pipe being unitarily formed and having a longitudinally extending securing section intermediate the length of each respective pipe, the securing section including at least one flat surface portion, each said pipe being of substantially circular cross-section adjacent each longitudinal end of the securing section; and a bracket body unitarily injected molded from a thermoplastic resin, such that the thermoplastic resin of the bracket body surrounds and engages the entire securing section of each said pipe and regions of each said pipe adjacent to the respective securing sections, whereby the surrounding engagement of the thermoplastic resin with the securing sections and regions of each said pipe adjacent to the securing sections prevents relative longitudinal and rotational movement of each said pipe relative to the bracket body.
