REVOLVING DISPLAY RACK Filed March 6, 1941 3 Sheefcs-Sheet 3 patented May l2, 1942 Anthony Vanderveld, Grand Rapids, Mich., as

signor to Grand Rapids Store Equipment Company, Grand Rapids, Mich, a corporation of Michigan Application March 6, 1941, Serial No. 332,034 8 Claims. .(01. s12 133)' This invention relates to a revolving display rack housed within a show case or cabinet, the rack being bodily movable forward from a position within the case to the front where'garments carried by the rack may be examined and reu moved. Racks of this type and character, in general, carry two rows or lines of garments, one back of the other, and for inspection and removal of the garments at the back, the rack is rotatable about a vertical axis. The immediate garment holding portion of the rack is longer than it is wide and any rotation of the rack when it is at an inner position within the show case would cause parts of the rack to strike against the back of the show case with danger of breakage or other damage. Also when the rack is at the front of the case and has been rotated from its normal position, any inward movement of the rack would cause similar damage to the case. Therefore, the revolving rack is held locked ;against rotation at all times except at the fore- .most position to which it can be moved. And when in such foremost position the rack is ro- ;tated, it is automatically locked against rear- -ward movement into the case until again at its first position to thereby insure against damage .to either the case or the rack from undesired contactengagement of them.

This general form of revolving rack with lockfling devices forthe purposes stated is old and well-known. My invention is directed to an improvement therein which greatly reduces manufacturing expense so that the rack structure to the applied to a show case unit may be manufacltured at a cost of approximately 50 to 60% of "What has been the previous cost for revolving display racks of the wardrobe type. In pursuance of the economy of manufacture with the resultant reduction of sales cost to the buying public, the invention consists in numerous novel constructions of simple and economical form but by means of which the locking against rotation when the rack is in one position and the looking of bodily movement when it is in another position, as previously mentioned, are assured; yet the construction may be produced at exceptionally low cost, all parts and their assembly and association being economically produced, and of great strength and durability.

For an understanding. of the invention by means of which the specified results are attained as well as other objects not at this time specifically enumerated, reference may behad to the folaccompanying drawings, in which,

Like reference characters refer to like parts .in the different figures of the drawings.

The wardrobe show case is of conventional form having spaced verticalends l, a back 2 and top 3 mainly of glass. At the bottom of the case a floor is provided including a horizontal open frame 4, the opening in which may be closed by removable floor sections 5 laid therein, the division line between the sections being midway between the ends of the case and running from front to rear. At their forward portions, adjacent edge portions of thefloor sections 5 are cut away so that when the two are placed together an elongated slot 6 is provided indicated in dotted lines in Fig. 2, which is from 'subst'antiallythe center point of the case fortracks consists of a channel member Ill secured at its ends to the rear side of the base member The one of which is a wood bar ll extending between the parts 1 and 8 and attached thereto and over which a fiat plate of metal I2 is placed and secured, having an edge portion extending beyond the inner side of the bar II for a distance as shown in Fig. 5. At the same side of the bar II a longitudinal rib is provided as shown, to which a vertical track plate or bar I3 of flat metal is permanently secured. These tracks spaced apart as shown are to movably carry the supporting carriage of the rack which carriage may be moved back and forth on the tracks.

The carriage consists of two side bars M of angle formation having vertical legs with horizontal legs at the upper edges ofthe vertical legs extending toward each other. Near the front of the side bars a cross channel having a horizontal upper web I5 is secured extending underneath the horizontal legs of the side bars and. welded or otherwise rigidly secured thereto. Front and prearirollers lfi traverse the channel track chip-b ing attached to t e vert al leg of th sid bar l4 adjacent such ha n l tra k- Similar rollers .l,6 are mounted on the vertical legof the opposite sidebar [4 and, lie upon the upper edge of the verticalgpositioned trackmemher 13. .;An :arm I! is permanently welded or otherwise secured to the same sidebar [4 near itsrearsendand extends downwardly, atits lowerendcarrying agrooved; roller l8 of a like construction to the rollers lfiand engaging. the track plate 13 at its lower edge (Fig. 5). i

A tubularpostJS' is weldedat its lower end to .theweb l5 oflthe channelgorossmember of the carriage and extends vertically therefrom through the slot 6 of the floor. At its .upper end .itis equipped with ,a circularfldisk 20 which is located horizontally. ,At ,diametricallvopposed edges .10f the disk notches are-gut. the purpose of which hereinafter appears. Y

The channel crossbar of the carriage having an upper web .15 has downwardly extending spaced flanges 2| (Rig. ;6),. .Below t e lower end of the post H) a channelilength having a horizontal ,web 22 and upwardly extending .flanges 2.31 s pla cdnas'shown inEi 6. with th "flanges 23' outside of the flanges ;2I. The contacting flanges 23 and 2| are permanently secured together by screws as shown in Fig. 4 or other equivalent connections. Such-flanges at their frontand rear sides have openings .24 the .axes of which are coincident and liein'a common horizontal and vertical plane.

To therear member 8 of the base a rod 25 is connected at one end and extends forward -to and enters the openings in therearflanges 2| and 23; and when the carriage is backof its front position it passes through the front openings 24, asindicated in :Figs. 2. and 3. Bumpers 25 are secured at the rear 0f the base member land at thefront of member 8 which the ends .of the carriage sides strike at their extremes of movement. At the forward extreme of movement indicated in dotted lines in Fig. 3, the

front end-of the rod"25 will be as shown in Fig.

6, entering only the openings 24 in the rear flanges 2| and 23 and not extending across the housing, completed by the under channel section described.

-A vertical shaft 21 is; mounted lengthwise of the; post 19, suitable sleeve bearings 28 being provided at the upper and lower end of the post for saidshaft. The shaft extends at both ends beyond the-ends of the pgst. At its lower end (Fig. 6) it reaches to the web;22;-of tlqie inder channel section of the housing described and bears thereagainst. Within the housing a short cylindrical disk or drum 29 is located and permanently secured to the lower end portion of the shaft 21. It and the shaft 21 have a diametrically disposed opening or passage therethrough which in one position of the drum is in horizontal alinenient with the openings 24. In such position the carriage may be moved back and forth from front to rear and Vice versa, the rod 25 passing through the alined openings. It is evident that when the rod 25 has entered or passed through the disk 29 no rotation of the shaft 21 about its vertical axis cantake-place. But when the carriage is moved to its front nost position and the rod 25 is located with reference to the disk 29 as shown in;Fig. 6, such shaft 2'! if free of locking rod 25 may be rotated; and as soon as it has rotated even a very short amount the carriage cannot be returned until the parts are returned to a r it gn s ch tha the h r q t "Opening throu -the dis and t -l e end'bf the ha isinal n m n W thhe en 24? ;A rack is mounted atthe "upper projecting end pqrtign of theshafti-l above thepost 19. I -nthe specific;disclosureshown thelrack is for holding pants. In structure it comprises two elongatedparallel channels having vertical webs Jill :and oppositely extending ;fianges -3l located one in-front and -the;othe'r ;.back .of the upper part o f shaft 21 from which shaft locating and holding pins .32 extend through openings in the websfifl. Arms 33; made .froin. wirerod.are pivotally-mqunted onthegflanges fl as shown, each including .an upper horizontal section and a downwardly inclined lower section. Pants may ,be folded jovertheupperisectionof-the arms 33 and in practice retained against accidental movement thereon by; the spfings shown which vexerta'gripping action onll the .garment. Such form of holder for pants is not new; and need not be further.specificallydescribed. A horizontal plate '34 p is laid I overthe channels and se- Lcured jto .the upper flanges thereof, preventing disengagement o'f thearmsfiii.

Between; the vertical webs 30. of the, channel and at each side of the upp er..end portion of post 211a casting 35 is locatedandper nanently se'cured by bolts or screws. Each [of said castings..at,its outergedgeis vertically slotted and a lever 3,6 pivotally mounted between its ends is .located in..each.slot. A compression spring 31 mounted in alined openings in the post. 21 and the castings 35 normallyforces the upper end portions ofthe levers ,36 outwardly away from each other,v and moves thelowerend portions of thelevers toward .each other sothatpthey will .enterthe. notches in the disk20 when in conjunction therewith.

It is to be understood that the rack described may -be varied Lin 'nany; respects. ,Eor example, l in stead of. carrying. a large number. of bracket arms like fthose 'shown at.33, horizontal rods may be carriedby the rack at equal .distancesin front and back of thechannelmembers30, 3| through intervening .s pp rting.,.arms between the jrod and channels;i. and' over ;.said rods garment hangers 'ofyarioustypes may behookedland carried.

With thisiconstructionswhen the lackjsat its innepmsifion Withi 1. 9w. =i f 1 i 3, the rotatable. garrnent carrying hpper portion of the; rack is; locked against "rotation' n d. remains thus locked' all -of the ti ne that the-Lrod 251s engaged with the disk 29. When the rack is drawn forward to the dotted line position indicated in Fig. 3, rod 25 will be completely withdrawn from the disk 29, as in Fig. 6, whereupon so far as the locking rod 25 is concerned the rack may be rotated. However, at such position in order to free the rack for rotation the upper ends of the levers 36 which extend through slots in the overhead plate 34 are manually engaged and operated toward each other to disengage their lower ends from the notches in the disk 20.

As soon as the rack has rotated from the position shown in Figs. 1 and 3, the turning of the disk or drum 29 moves the opening therethrough out of alinement with the rod 25 so that any attempt to push the rack back into the case will fail because a side of the disk will come against the end of rod 25. It is only in one position, and that is with the opening in the disk or drum 29 in alinement with the openings 24 and with the axis of the rod 25, that the rack may be pushed back in the case. Such construction insures no contact engagement of the rack with parts of the enclosing show case. It is of course to be understood that the positive lock which is provided by the notches in the disk and levers 36 may be replaced by a yielding connection between said levers and disk by making the notches of a different form with cam sides instead of straight shoulders as shown.

The described construction has proven very practical and useful and is particularly economical to build. The carriage construction for the housing of diskor drum 29 and the simple looking rod used therewith with an insurance that the front free end of the locking rod will be held and supported at all times, together with the fact that the parts from which the construction is made are in general all stock metal forms such as angles, channels, plates, tubes androds, makes the construction one which is of exceptional economy, strength and durability, such durability following because of simplicity of construction without any parts liable to cut or bind or get out of order.
