This invention relates to a rocking cushion slide.

Heretofore in the slide industry, slides have been produced which have a stem or center anchoring member that is rigidly associated with the slide body and said slide body has been of suitable formation such as kan integral cast construction or of multiple sheet metal construction, or of a molded construction reenforced with metal.

Likewise, so-called rocking stern slides have been used inthe industry and these may be of molded or cast base construction, providing a central chamber or a sheet metal base construc tion providing acentral chambery and mounted in the central chamber is a headed anchoring member whereby the slide is anchored to a furniture leg or the like. Y

Slides alsoV have been used in the industry wherein a cushion member has been interposed between the slide base and the end of the furniture leg. Y

Each of the aforesaid' types of construction, by reasonv thereof, has inherent disadvantages of lack of strength, of being noisy, inability to rock or inability .to be driven into an anchoring connecticn with the leg to be supported thereby.

The present invention includes all of the advantages of these slides, to wit, it can be driven' for anchorage to a furniture leg, it is cushioned for Contact between the leg and the slide body, and may be cushioned within the central cham ber for eliminating the noise incident to the conneet-ion between the anchoring member and the slide body and has sufficient strength that it will not break when in use. in other words, it will have a relatively long life.

The full nature of the invention will be-understood from the accompanying drawing and the following description and claims:-

, In the drawing'similar numerals indicate like or similar parts., For example, numbers of the one hundred series refer to parts shown in Fig. 1 and similar numbers of the two hundred series refer to similar or like parts in Fig. 2, and so on for the several figures. body in Fig. 1 is indicated by the numeral 110 and the nail body in Fig. 15 is indicated by the numeral 1510. All parts are numbered in all of the figures in this manner and to reduce the specic description, only the respective departures in each figure will be mentioned hereinafter, it being understood that the numerals on the drawing indicating parts not mentioned, refer to like parts and for like purposes.

I n Fig. 1 of the drawing, 110 indicates an upstanding anchoring member which herein is shown as of the nail type, although a so-called ldriving screw might be substituted therefor. The vnail 110 terminates in an enlargement or head 111 which has a rounded peripheral edge l112 and a flat top 113. The purpose of this `lattop is that it will engage the relatively flat interior surface 114 of the base member 115 and in the driv- 'ing of the slide on to the furniture leg, the spike portion 110 will be specifically perpendicular to the plane of the base ofthe slide, thereby insuring'correct driving and anchorage of the slide. The base of the-slide has an upwardly and inwardlydirected peripheral portion llfwhich For example, thel nail vgreater resistance to the tilting action.

in Fig. 1 is turned inwardly as at 117 to engage or overhang the portion 118 of a top plate 119. The top plate 119 is centrally apertured as at 120 andthe upstanding member 110 extends through the aperture and may rock therein without interference from the wall of the aperture. Mounted on the top plate and as shown in Fig. l, partially nested within the portion 117 is a cushion member 121 that is apertured as at 122 and the upstanding portion 110 extends through the aperture 122. The cushion 121 is adapted to engage the end of the furniture leg.

This cushion 122 also has another function, to wit when the slide is to be driven on to the leg, the top 113 thereof engages the surface 114 and impact or a hammer blow on the exterior of the base 115 serves to drive the nail or spike into the furniture leg. If this driving movement is continued to the proper degree, the cushion 121 will be partially compressed. After the force of impact or driving force is removed, the cushion 121 reexpands and tends to push the slide away from the furniture leg. Thistends to force the top plate downwardly along the upstanding member 110 until the enlargement 111 or head engages .the bottom side of the top plate 119 adjacent the opening 120. Enlargement 111 is of greater-.area than the opening 120.

Herein the top plate v119having the base engageable interlocking portion 118 is extended downwardly as yat 123 and this forms cup in which, if desired, may be mounted a cushion member 124 having `the central aperture 125 therein.

In the initial manufacture of the slide, the cushion member 124 is considerably expanded and is nested in the inverted cup formed by the top plate and the portion 123 extending therefrom.V When the top plate and the base plate are lassociated together, the two are forced together in nested relation, thereby compressing the cushion member 124 and putting the same under constraint. The top plate is then turned inwardly into interlocking relation, .as shown at 117, the latter portion engaging portion 118 and locking the construction together. Thereafter the cushion member 121 is mounted on the slide and the latter serves the two purposes before mentioned.

In Fig. V2 like or similar parts are indicated by similar numerals of the two hundred series. Specifically this form -of the invention differs from the form shown in Fig. 1 in that the base plate 215, which includes the rupwardly peripheral portion 216, is offset inwardly as at 227 `for obtaining a greater mechanical locking than is obtained by the portion 217. This annular inwardly offsetting valso reenforces the base of the slide.

In both forms of the invention and in all subsequent forms, it will be observed that the normal 'action of the slide is such that the head 111 preferably does not contact the base but must contact the basefor the driving of the slide onto the furniture leg. l Likewise in both forms of `this invention and in the remaining forms where- .in the slide enclosed cushion member is employed, the retention of such cushion member in the slide and under compression insures In other words, when the ltilting force is removed, this cushion member tends Vto*immediately realign the respective parts so that the slide and its anchorage will maintain the perpendicular relation shown in Fig. 1.

In Fig. 3 there is illustrated a modified form of the invention, wherein all of the advantages of the metallic slide, so far as strength is concerned, is retained or embodied therein and a non-metallic sliding surface is provided. In this form of the invention, there is molded upon the metallic base 315 an outer base 330 which by reason vof the portion 331 is retained on the metal base slide structure. This molded base structure is of a non-shatterable material, such as relatively hard rubber of any desired color. In other words, the base 330 may be hammered for driving on the slide without the danger of shattering. In other words, this form of the invention is identical with that shown in Fig. 1 with the addition of the external auxiliary molded base.

In Fig. 4 there is illustrated a modified form of the invention which differs from the form shown in Fig. 3 in that it is arranged to be of a vitreous or shatterable molded material, such as glass or of shatterable phenol condensation type. In this form of the invention, the auxiliary base 430 includes a central aperture. The Slide is attached to the furniture by inserting a tool in the aperture 432 to engage the base 415 and then the slide is driven on as before set forth. In this form of the invention also, the metal base 415 instead of having a side wall 416 arcuate in radial section, has an upstanding substantially vertical cross section and terminates in an inturned flange 417.

In Fig. 5 there is illustrated a modified form of the invention and this form differs from that shown in Fig. 1 in that the top plate 519 has a downwardly directed peripheral Wall 523 that terminates short of engaging the base. The cushion insert 524 in this form of the invention, is shown provided with a projecting flange 529. The other peripheral skirt 623 which, in this instance, similar to Fig. l, also engages the base 625.

In Fig. 7 a modified form of the invention is illustrated, wherein the depending side wall of 'the top plate is closely associated with the upstanding outer side wall of the base, and'inl this respect the invention is similar to that'illustrated in Fig. 4. In this form of the invention also, there is an offsetting but instead of being in the outer base forming member, the same is provided in the top and in this respect it is a reversal of the form shown in Fig. 2. In Fig. 7, the top plate 719 includes an upwardly directed annular lflange portion 727 and a curved portion 7,18 that is gripped by the upper edge 717 of the outwardly andupwardly curved side wall 716 of the base 715.

The top plate has a depending skirt 723 that is positioned imediately adjacent and in engage' ment with portion 716.

Fig. 8 illustrates a form of the invention Wherein the base plate 815`has an upwardly directed side wall 81-6 and an inwardlylocking portion 817 similar .to that shown in 1. Thetopplate 819 4has a curved portion 818 that terminates at 823.

superimposed upon the base plate is an auxiliary baserplate 835 with an upstanding peripheral por- `tion 834 that terminates in an edge 833 which abuts the edge 823. Both top plate and auxiliary base plate are retained in chamber forming relaltion `by the outer base plate.

In Fig. 9 there is illustrated a form of the in;

ing the curved vention which is substantially a duplicate of that shown in Fig. 8, except that the auxiliary base plate 935 is centrally apertured as at`932, so that for driving purposes the head of the anchoring member maydirectly engage the base 915 and in all other respects this form of the invention is similar to that shown in Fig. 8. N l

In Fig. lo'there is illustrated a form of the invention that is somewhat similar to'Fig. 7, except that the top plate is not corrugated. In other words, the form of the invention shown in Fig. 10 differs from that shown in Fig. 1 by the depending side wall 1023 ofthe top plate 1019 closely engagouter wallk 1016 of the base 1015, the parts being locked together as at 1017.

Fig. 11 is substantially similar to Fig. 10, except that instead of the depending wall carried bythe top plate thereof, terminating adjacent the bottom or nat portion of the base, the depending portion terminates lintermediate the plane of the base and the top plate and in this respect,is similar to the forms of the invention shown in Figs. 5, 8 and 9, except that like Figs. 8 and 9, the

top plate in the present form closely engages the side wall portion 1116 of the base member 1115. The top plate 1119 having its portion 1118 and depending wall 1123 is locked in slide forming relation by the edge 1117 of Ythe base member 1115.

Fig. 12 is similarvto Fig. 10 in all respects, except the top plate 1219 adjacent the aperture 1220 is extended upwardly in collarformation as at 1236. p y

In Fig. 13, the structure illustrated is the same as that shown in Figs. 10 and 12, except that the top plate 1319 has its central aperture 1320 defined bya downwardly directed extension or collar 1336.

In Fig.` 14 there is illustrated a modification substantially similar to that shown in Fig. 10, except that the locking portion of the base 1417 includes an upstanding collar 1437, and the same forms' an annular groove `to receive the outer cushion' member 11121. In this respect Fig. 14 illustrates a form of the invention somewhat similar to the form shown in Fig. 7, except that the recess for the outer cushion member, in this instance, is formed by the base member and not by the top member, as in Fig. 7. p

In Fig. 15 a modied form of the invention is illustrated, wherein the base member is substantially identical to that shown in Fig. 1. The top plate 1519, however, is provided with the depending portion 1518 and thence with an outwardly directed, curved outline in radial section, extension 1523 which terminates in an inturned portion 15210 thatbears upon the

base

15,15. YThe base 1515 includes the side 1516 and the locking portion 1517. f

t will, of course, be understood that thetop lplate in any one of the gures, except Fig. 12

may `be provided. with a downwardly directed collar indicated, by the numeral n plus 36, where n, is the number of the ligure multiplied by onel hundred. Also any one of the top plates except that shown in Fig. 13, may have an upwardly directed collar defining the aperture and said collar would bear the same numeral.

It will also be apparent that in those forms of the invention wherein the auxiliary base may be employed.

'Ihe various forms of anchoring the base and top plate together may bereadily interchanged in the various forms of the invention.

It is also to be noted that while the preferred Vouter metal base form of the invention illustrates in each instance a head structure for the anchoring member wherein there is provided a curved side wall that terminates in a` hat head, a frusto conical head may be substituted, see Fig. 16, or a partially spherical head may be substituted therefor. The frusto conical'head would be preferred to the rounded` head,v because voi the so-called self centering actionobtained in driving.

While the anchoring 'member is shown as a nail,l as before mentioned, it may be of driving screw formation, see Fig. 16, or it may be of standard detachable lcaster pintle form.
