A bracket for holding a rigid duct, such as an air conditioner coolant duct in a motor vehicle, including a mounting part and a duct retaining part. The duct retaining part has a duct receptacle for a least partially surrounding the duct and including spaced, inwardly extending clamping projections for providing compressive elastic contact with the duct.
This application is a continuation of copending International application PCT/EP99/05319 filed Jul. 26, 1999, which is incorporated by reference herein, claiming priority from German patent application No. 198 40 136.1 filed Sep. 3, 1998. The International application was published in German on Mar. 16, 2000, by the International Bureau.
The invention relates to a bracket and a system for retaining rigid ducts in a vehicle, applicable to the ducts of an air-conditioning system.
According to the invention a bracket for holding a rigid duct includes a mounting part for attachment to a vehicle body part and a duct retaining part connected thereto. The duct retaining part includes a duct receptacle for at least partially surrounding a duct and having spaced inwardly extending clamping projections for providing compressive elastic contact with the duct.
The clamping projections can be axial ribs that can influence the degree of decoupling as a result of their characteristics, e.g. length, thickness, number and material, but especially their number. It has been demonstrated that adequate decoupling can be ensured by coaxial ribs arranged at intervals of 45° in the interior of the duct receptacle.
However, the receptacle can also be designed in the form of an opening having two legs with an open gap between them on the side where the duct is inserted. The duct can, in a simple manner, be pressed through the gap into the receptacle against the clamping force and be retained therein by elastic compression. This embodiment also represents a rapid-action coupling with the damping properties in accordance with the object of the invention. The free ends of the legs can be inwardly tapered to facilitate the pressing-in. This embodiment—like the aforementioned embodiment—simplifies assembly and also disassembly of the retained duct.
FIG. 1 is a perspective view of a retaining system in accordance with an embodiment of the invention for two rigid ducts.
FIG. 1 shows a duct retaining system 1 made of HYTREL, an elastic engineering material with a low temperature coefficient for two refrigerant ducts 2 and 3 of an air conditioner (not shown) in a passenger car. The pressurized refrigerant duct 2 is located between the condenser of the air conditioner and an expansion valve, and the refrigerant suction duct 3 is located between the expansion valve and the compressor of the air conditioner. Duct 2 is parallel to a first duct section 3 in the vicinity of the retaining system 1. The refrigerant suction duct 3 also has an angled second duct section 3 a in the vicinity of the retaining system. The retaining system 1 is intended to be placed on a cover panel formed between longitudinal members, and has a mounting part 4 with two oblong holes 5 for screw-mounting to the cover panel, and also has several duct retaining parts 6 and one retaining part 6 a, likewise made of HYTREL.
Duct retaining parts 6 are integrally joined to the mounting part 4 and the retaining part 6 a is joined to the mounting part 4 by means of a dovetail slide P. Each retaining part has a duct receptacle 7 for the relevant duct 2 or 3. By means of the dovetail slide P retaining part 6 a is arranged to be movable on the mounting part 4 perpendicular to the axis A of its receptacle 7 (FIGS. 2a, 2 b) and parallel to the duct section 3, in the plane defined by the first duct section 3 and second duct section 3 a. Arranged within duct receptacle 7 are clamping ribs 8 that face radially inward and are spaced apart from one another, preferably at angular spacing of 45° or less. When duct receptacle 7 is closed, the ribs 8 are elastically pressed against the relevant duct 1 or 3, holding it centered in the receptacle 7. The duct receptacles 7 are selected according to the diameter of the duct 2 or 3 that they are to hold.
1. A bracket for holding a rigid duct in a vehicle comprising a mounting part and a duct retaining part connected thereto, said duct retaining part comprising a duct receptacle for completely surrounding a retained duct and having radially inwardly extending clamping projections at substantially equal distances from each other for providing compressive elastic contact with said duct, wherein said duct retaining part comprises first and second portions arranged to extend along an axis of a retained duct, said portions being joined by an integral hinge portion arranged to pivot parallel to said axis.
