.NOISE AND VIBRATlON-ATTENUATING HANGER This invention relates to a novel noise and vibration-attenuating hanger.
In one conventional vibration-attenuating hanger heretofore proposed, thehanger included a resilient element sandwichedbetweenrigid plates, aligned holes throughthe plates and the resilient element, an upstanding hanger engaging the lower plate and extending upwardly through the'holes and a depending hanger engaging the upper plate and extending downwardly through the'holes. These prior art hangers are 7 generally satisfactory, but the central hole through the resilient element reduces theload to which such hangers of a given size can be subjected and requires a larger resilient element than would otherwise be'necessary.
In the noise and vibration-attenuating hanger of the present invention, an upstanding hanger extends upwardly adjacent a pair of opposite sidewalls of a resilient element interposed between upper and lower rigid plates and a depending hanger extends downwardly adjacent another pair of opposite sidewalls of the resilient element. In the preferred embodi- =ment of the invention, the hangers are V-shaped and the bulge outwardly when the resilient element is placed under compression. This tendency of the sidewalls to bulge urges that adjacentportions of the hangers outwardly so thatthe upstanding hanger is urged away from theedges of theupper rigid plate and the depending hanger is urged away from the edges of the lower plate. Such engagement would cause the hangersto bridge the plates and nullify "the effect of the resilient element.
Another feature of the present inventioiiis that the hangers frictionally engage. the sidewalls of the resilient material so that the hanger. elementswill not become accidentally disassembled.
For a morecomplete understanding of the present invention, reference canbezmade to the detailed description which 'followsand to theaccompanying drawing in which:
FIG. 1 is an.exploded prospective view of the resilient ele ment and the rigid .plates which engage the upper and lower surfaces thereof;
F l0. 2 is a front elevation of the hanger;
FIG. 3 is a cross-sectional view taken'along the line 3-3 of F IG. 2 looking in the direction of the arrows;
FIG. 4 is a perspective view of an alternative form of the :hanger; and
FIG. Sis a cross-sectional view taken along the line 5-5 of FIG. 4 looking in the direction of the arrows.
Referring to the drawing, the vibration-attenuating hanger includes a resilient element interposed between upper and lower rigid plates 11 and 12, respectively, an upstanding hanger l3 engaging. the lower plate 12.and extending upwardly and a depending hanger l4 engaging the upper plate 11 and extending downwardly. The hanger can be used, for example, for hanging heavy objects from a ceiling.
The resilient element 10 is preferably a solid block of an -.elastomeric. material capable of attenuating vibration and (noise. Neoprene is a suitable material which not only has these properties, but in addition has 'long aging properties, resistance to chemicals and oil and stability over a wide temperaturerange.
Thehangers are preferably. steel wires which are zinc plated .or galvanized to resist wear and corrosion and bent generally in the shapeof a V. The upstanding ends 13a of the hanger l3 engage aligned holes 15 and 16 in the bottom plate 12 and in the bottom of theresilient element 10. The hanger 13 extends outwardly below and in engagement with the bottom plate 12 and then upwardly adjacent the sidewalls 22 of the resilient element in the form of an inverted V. Similarly, the ends of the depending hanger 14 engage aligned holes 17 and 18in the upper plate 11 and in the upper surface of the resilient element 10. The hanger extends outwardly across'the top of the upper plate 11 and then downwardly adjacent different sidewalls 19 of the resilient element in the form of a V.
The pair of opposite sidewalls 19 slope downwardly and inwardly from the upper surface 20 to the lower surface 21 of the resilient element to conform to the shape of the hanger 14. The other pair of opposite sidewalls 22 slope downwardly and outwardly from the upper surface 20 to the lower surface 21 to conform to the shape of the upstanding hanger 13. The upper and lower surfaces 20 and 21, respectively, of the resilient block are rectangular in shape with their longer dimensions oriented at right angles to each other.
The hangers frictionally engage the sidewalls of the resilient element so that they will not become accidentally'disassembled from the resilient element while they are in storage or in shipment.
In the alternative embodiment of the hanger illustrated in FIGS. 4 and 5, the resilient element 10 contains slots 23 in the upper andlower surfaces to receive the ends of the hangers, and the upper and lower rigidplates l1 and 12, respectively, have aligned slots 24 therein. Also, the sidewalls of the resilient element contain grooves 25 to receive the adjacent portions of the hangers therein.
The smaller dimensions of the upper and lower rigid'plates 11 and 12, respectively, are slightly less than the corresponding dimensions of the surfaces of the resilient element which they engage, so that the upstanding hanger 13 will not engage the upper plate 11 andthe depending hanger 14 will not engage the lower plate 12. Obviously, if either hanger were to bridge both plates, the hanger would nullify the-effect of the resilient element. Such bridging should not occur in the hanger because as the load increases the-compressingeffect on the resilient element will tend to bulge the sidewalls thereof and urge the adjacent portions of the hangers outwardly away from the edges of the plates.
The invention has been shown in preferred forms and by way of example only, and obviously various modificationsmay be made therein without departing from the spirit of the invention. The invention, therefore, should not be limited'to any specified form or embodiment'except insofar as such limitations are expressly set forth in the claims.
I claim:
