(c1. 24a-35s) 4 Claims.
This invention relates to furniture and more particularly to furniture mounting means incorporating vibration isolator or absorbing devices.
Vibration and shock developed in railroad cars and other vehicles are transmitted through the underframing and body to the supporting means for furniture in the car rooms. When furniture, such as tables, are supported on the car wall as well as on legs, the vibration and shock are transmitted from the car wall and the fioor. The effect of vibration and shock transmitted to tables and other furniture is objectionable to vehicle passengers.
An object of the invention is to reduce vibration and shock transmitted to vehicle furniture through the provision of isolator devices in the supporting means.
Another object of the invention is to provide a novel isolator device of the compression type.
A further object of the invention is to reduce the vibration and shock flowing to a table of the wall attachment type through the use of isolator devices in the supports.y
These and other objects of the invention will be apparent to those skilled in the art from a study of the following description and accompanying drawings, in which:
Figure 1 isa perspective view of a fragment of a vehicle room having a table set up therein.
Figure 2 is a vertical elevational view in the room showing a portion of the table and one of the wall supports for the table.
Figure 3 is a sectional view taken on line 3-3 of Figure 2.
Figure 4 is a view similar to Figure 1 showing hinged supporting means for the table.
lFigure 5 is a vertical elevational view in the room showing a portion of the table and with one of the hinged supporting means partly in section taken on line 5 5 of Figure 6.
Figure 6 is a view taken on line 6-6 of Figure 5.
Figure 7 is an end view of the lower portion of the table leg and associated vibration isolator device.
Figure 8 is a side view ofthe lower portion of the table leg with an applied isolatorv device shown in section.
The invention is shown applied to a table I0 located in a vehicle room, which may be the interior of a railroad car, of which an outer wall II and a floor I2 are illustrated. The table is preferably of the detachable wall type used in railroad cars and is formed of sheet wood or other suitable material.
2 f The table is preferably provided vwith a three point support consistingof legA I3 adjacent one end and aA pair of spaced supporting means I4 at the other end. Wall II has a continuous anchor stripV I5 extending longitudinally thereof having a slot formed by an under turned flange I6 providing an anchor for hanger brackets I'I forming a part of the supportingmeans. These brackets have an out turned upper flange I8 adapted to be inserted into Athe slot and over the underlyinganehor flange of strip I6 and that also have an out turned base portion I9 for carrying the table. Between the hanger bracket bases I9 andthe wall end portion of the table, I arrange vibration and shock isolator devices 20. y'
In the arrangement shown in Figures 4 to 6 inclusive, there is ar backing strip 2| between the anchor strip and wall I-I and such backing strip projects beneath the anchor strip and serves as a protector plate for the Wall. This form of the invention diers from that shown in Figures 1 to 3 inclusive in that the supporting bracket or hanger means is formed of two hinged sections instead of being rigid. The upper section 22 of this hinged hanger supporting means has the out turned flange I8 adapted to be inserted over the flange I6 of the anchor strip and is connected with aflower section 23 by hinge 24. The lower section 23 has an outwardly extending table supporting base flange I9 as previously described. In this form of the invention, the isolator device 20 is arrangedbetween the base flange I9 and the'wall end portion of the table. Member 22 hasoppositely disposed bumper devices 25 and 26 secured thereto, the device 26 being located to engage kagainst the depending portion of the-backingstrip and the bumper device 25 serving to be engaged'by the table top when it is swung upwardly.
The isolator devices of the4 Wall supported hanger brackets shown in both forms of the invention are similar so that a description of one device will sumce. 4A facing strip 2l. applied to the top of the basesupporting flange I9 provides a seat for the cup-shaped base 28 of the isolator device. A bowl-shaped rubber member 29 formed with a cylindrical base portion is.
mounted in the base 28 to which it is vulcanized or bonded and the upper edge portions of member 29 are bonded to thebase of an angular strip 30 adapted to be attached to the wall end portion of the table by screws 3|. Base flange I9, facing strip 21, base 28 and the circular base portion of the rubber member 29 areformed with aligned openings for the reception of bolt 32 and an internally threaded metal sleeve 33 is vulcanized in the opening of member 29 for engagement by bolt 32. The isolator device is clamped on the supporting bracket or hanger ange I9 by the engagement of bolt 32 with sleeve 33 and the angular istrip o'f the device is attached to the table by screws 3 I. The isolator device is formed of a unitary structure that is readily applied to or detached from the table and the hanger support. These isolators serve to absorb wall vibrations and shocks before they reach the table.
The leg I3 may have a hinsedattachment with the table, of a conventional nature, and the foot of the leg is provided with a vibration and s'hock isolator device 40. This device isgenerallysimilar to that utilized between the Wall hanger'brackets and the table. A bowl-shaped rubber member 4l has its upper edge portion bonded to a metal platen that is adaptedto, be detechably Secured to the, bottom of the tablgjeg byscrews ,43. The reduced diameter base portion ofthe rubber member 4l is cylindrical and bonded to the inside of aangedmetaljannular 'basemember 44, lThe base member and, the baise portion of the rubber member have, centrally aligned openings andan internallythreaded sleeve 4 5, lies in the opening in. the, rubbermember and iS Secured by being vulcanized t o the;ru bbe r jmember. The head of bolt i provides supporting means 'for the leg andits shank 41 Vis screwed into `the metal sleeve 45 of the -isolator This -isolator device is for1n ed ase unitary struct-ureA and caribe readily attached to lor 'detachedffrom thebottoln ofthe table leg.
It will be observed that the rubber member portionof the isolator devices Supportsthelegjror the table under compression and Ais adapted to absorb vibration and` shock-,transmitted `from the car ooror walljsogthat veryrlittieshcck or vibration reachesthe table-l.
