Problems solved by technology

[0004] Some plumbing covers have the disadvantage of not being able to open to at least 90 degrees to provide smooth access to the base member
In addition, when using a fully openable pipe cover, due to space constraints, it is often restricted by the environment, so that the cover cannot be fully opened on a part or several parts of the pipe system

Embodiment Construction

[0027] A first embodiment of a duct section according to the invention will be described with reference to FIGS. 1 to 10 . Figure 1 shows a duct section 10 comprising a base 20 and a cover 40 with a hinge arrangement. The duct section 10 may be made of any suitable material, but is preferably made of a plastic material such as PVC.

[0028] As shown in FIG. 2, the base 20 is generally formed in a U-shape and includes a base plate 22 and side walls 24, 24', which may be formed in one piece or may be fixed together. Base plate 22 and side walls 24, 24' define a receiving channel 26 for wiring or the like. The distal end portion of side wall 24, 24' preferably includes similar but just reversed base hooks 28, 30, each consisting of an inwardly directed first flange portion 32 and a first flange portion forming an inverted "J" shape. Two parts 34 are formed. The mechanism formed by the two base clasps enables reversible mounting of the lid 40 and opening of the lid in either fa...

Abstract

A hinged duct system with a hinged cover is provided that includes a base member and a duct cover. The base member has a bottom wall and sidewalls defining a receiving channel. A distal end of at least one of the sidewalls includes a base hook having an inwardly directed flange portion and a convex portion extending outwardly from the receiving channel towards the at least one sidewall. A distal end of the convex portion is spaced from the flange portion to define a cavity therebetween. The duct cover is hingedly attached to the at least one sidewall. The duct cover includes at least one curved end portion forming a hinge end section. The hinge end section includes a cover hook having a distal end receivable in the base member cavity and a cover flange spaced inwardly from the cover hook. When the duct cover is mounted to the base member the cover flange abuts the convex portion of the base hook with a pre-load pressure that creates a point of contact pressure engagement point on the convex portion.

Description

[0001] Applicant declares that the filing date of U.S. Provisional Patent Application Serial No. 60 / 209299, filed June 5, 2000, is claimed as the priority date under 35 U.S.C. § 119(e), hereby incorporated by reference Instead, the entire contents of this application are incorporated into the present invention. technical field [0002] The present invention generally relates to a cable duct system for wiring including a base and a cover. More particularly, the present invention relates to a hinge arrangement between a cover and a base in a piping system which allows the cover to be rotated from a fully closed position to a fully open position while selectively clamping the piping cover held in each or all positions between the closed and open positions. Background technique [0003] Many raceway and conduit systems are known for routing different types of wires and cables. A typical piping or conduit system consists of a base member and a cover, wherein the cover can be hi...
