Description
Febp?, 1933. R. J. LoocK CUSHIONING DEVICE Filed April 50, 1930 Patented Feb. 7, 1933 `UNITED STATES Lagen@ GUSHIONNG 1 DEVICE Application filed April 30,
This invention relates to a cushioning device for building closures, and more particularly to such devices in which utilization is made of the resiliency of the material, as well 5 as the compression of air, to obtain the cushioning effect.
The object of the invention is to produce a simply made, inexpensive cushioning device i i A 1 Y p y.
.the top of the dome. This construction leaves Athevvalls vsurroun ding thehollow or recessyofz@ which has a wide range of application, and 1G one which can be attached to present structures without modifications. Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly lf pointed out in the appended claims. Y
In the drawing like reference numerals indicate like parts throughout the several igures, in which Fig. 1 is a perspective showing the cush'- 20. ioning device applied to the door of an automobile, and specifically as lying between the hinge members of such a door, the attachment being made by a screw used to holdk the F hinge in place. 2J Fig. 2 is a plan view of the detached cushv ioning device.
Fig. 3 is a section through the device, and Fig. 4 is a section through the device as it appears under compression,
Fig. 5 is a view similar to Fig. 3 showing a slightly modified form in which the extension 19 is omitted', andutilization madeof an aperture in the base to insert a screw, and Fig. 6 is a sectional view of this. modified form.
In Fig. 1 are shown a frame element 10 and a door element 11 of an automobile. It will be appreciated that these two elements are -indicture ,'20 is provided for the insertion ofthe .attaching screw 15. Y y
l/Yhile the `basehas been. described ,asf'sub- Stanti'ally circular, it will be appreciated that this base,I may Vhave fanyfform. Surmounting @55 "the baseisfadome shaped portion 21 which 'is hollowed Ias ;at]22,; imperforate lat thefbase, but4 provided .jwith la restricted opening323 at the rdome ofa minimum thickness at the point 124,; zand increasing thickness as 'i it :ap- @proaches lthe base. The merits vof this formation will be' apparent hereinafter.
Advantage, is taken efboui the. eushicaingitt i qualities of thematerial offwhi'h thevldevice ,is made, lwhich is -rubb'er ,of v`considerable stiifness, :andalso of the compressionof the "airentrapped inthe hollow 22, when theolosure is"clos"ed. As will l be "faclQPueiit--from3(l 1 :perusal ofk-Fig. fi, where thedoor` 11 is shown as closed;againstl the'fjain ``10`,fthe fair inthe hollow of the cushion is confinedV therein ,las 'indicate'd, While the wall [surrounding the 1 apex `-of the ldomef is shown as flattened under@i275 rfthe action oflthefclosure. ln'arrivingat this condition,Y it be apparent' that'V 'irstQthe 'door 'willfflex one side of thedome slightly Qand some of theentrappedairwill be'rl Sed p before 'the door closes completely the op Vat the ,apex of ,the f 'doinel Afterfthefdoor covers the apex ofthe dome,- no moreair will 'be permitted', to escapeand`fromthispoint on, the fdevice reliesfas fwell 4upon the compression f the air for fits cushioning ,gf'fecti asnponjthe 'distortion of 'the i walls of `jthe dome. As v,pointed out; these .wallsY become thickerias. theyiapproach, the base/land consequently -the cushioning effect, Vvdue `to the thickening of the walls vas well as thecom-Fim pression of the air, increases as the door reaches a closed condition.
AIt will be appreciated by reason of this action, that advantage is taken of both resiliency of the materialas well as the compressibility of the air, to produce a satisfactory cushioningdevice, vand this produces a cushioning of a wider range of application than'one which would rely solely upon the resiliency of the materiah'or solely upon the?100 `2v i y 1,896,908
compression of the air, as it permits the escape of some of the air, especially when the width between the faces of the elements to be cushioned is narrow, as shown in Fig. 4, while at the same time, if this space were wide less air would be permitted to escape and a satisfactory cushioning eect would be obtained for such wider space.
In Fig. 5 is shown a slightly modied form. Here the extension 19 is omitted and the basek made in the form ofa true circle. An' aperture 26 is formed in the base inalignmentV with the restricted opening in the apex of device to the'wall. .'Ihe dome 25 is otherwise i the d-ome through both of which openings the screw 27 .is insertedv to attach the cushioning similar to the domein'the preferred form. This modified form is capable of a variety of uses, particularly on house doors, screen doors, and on the legs of chairs, typewriters,
.adding machine, toilet seats, portable ma- Vvchines of different kinds, and for all vpur-v poses lwhere a cushioning device under anything would eliminate noises or scraping, vor
Vwhere'a cushion is an advantage or desirable Y to be used between two movable parts.
It will be appreciated that in this modified lforni the iexing of the dome protectsand further restricts the opening in the apex thereof so that it will partly cover vthe head of the screw and thereby .avoid any scratch- 'ing that the head of the screw would cause i to surfaces yon which an articles carrying 5 this cushioning device would be placed.
What is claimed is: l l( In a cushioning device,a fiat base ofy f 'hardrubber or the like, a dome formed on i Y l which the walls of the dome'are arcuate and v "said base, a recess formed in said dome and opening only at the apex thereof. Y
` 2. AThe 'cushioning device of claim 1, in
increase in vwidth as they approach the base.l
3.' In combination withla jam and a hinged closure, a cushioning'device lying; between said hinged elements in such a waythat a lateral approach of the closure is produced, la cushioning device consisting of va'dome shaped element, mounted upon one ofthe.V said closure elements, and made hollow with an'openinfg at the apex thereof, tov entrap 'air' when the closure has 'swung sufficiently to.
cause 'a cl'osin-'gvof4 the opening at lthe apex.`v
VIn testimony whereof I afli-x my signature.; v ROBERT J. LOOCK..
