Abstract
ABSTRACT
Trunks and luggage having retractable wheels connected to a wheeling handle. The motion of each wheel is controlled by a cam slot so that the wheel moves out when the handle is extended but returns to storage position when the handle is retracted. Any required lost motion in extending the handle is provided by either an interlocking wire loop or a curved cam slot.

Summary of the Invention The invention relates ko a luggage case wherein there is the combination of an opening in a wall thereof, door ~neans registerable with the opening, wheel means stored in the case acljacent the opening, operating means for simultaneously extending and retracting the wheel means and openln~ and closin~ the door means, and handle means for actuating the operating means. The invention relates to the improvement in which: the wheel means comprises a wheel mounted on a wheel support member which is pivotally supported by the luggage case and has a first slot; and the operating means comprises a second slot adjacent the first slot, slot engaging means extending through both the slots, and connection means connected to the slot engaging means and to the handle means.
Thus, the invention comprises generally a trunk or luggage case having a wheeling handle Gperatively connected to a pair of extensible wheels. The motion of each wheel is controlled by a cam slot so that the wheel moves out when the handle is extended but is arranged to return to storage position when the handle is retracted. A door is provided for each wheel to ~eep out the elements. The mechanism preferably comprises an elongated wire loop connected to a pivot pin which goes through the cam slot.
In one embodiment there is a sliding door which opens before the wheel is ejected. A~curved cam slot provides any required lost motion in extending the handle.
In another embodiment the door is spring-loaded and opened by the ejection of the wheel. A stop is provided to dm~ 3 -~5~ 6 hold tl~e door open while the han~le is extende~. ~ny re~uired los~ mo-tion in extending the handle is provided by llavin~ ~he handle legs engage a wheel wire loop after it has been substantially extended.
In a trunk or large case lost motion may not be needed, so that actuation of the handle operates directly on the wheel mechanisms.

Specific Examples of Invention Referring now ~o Figs. 1 to 4 ~here is illustrated therein a luggage case made in accordance with this invention. .The wheeling handle lO0 is U-shaped and comprises horizontal portion .
101 storable in recess 101a and having at its encs a pair of vertical members 102. Vertical members 102 connect to the mechanisms for wheels 111, as explained below, so that when the wheeling handle 100 is fully extended the wheels 111 are extended but when the horizontal portion lOl of wheeling handle 100 is stored in recess 101a the vertical members 102 are stored within the luggage case and the wheels 111 are retracted.
Locking means are provided to maintain the wheeling handle 100 in the selected extended or retracted position. The locking means comprise transverse locking rods 151 and 152 spacea adjacen recess 101a and having manip~lable ends 151a and lS2a in recess 9 .
~ocking rods lSl and 152 are supported by tube 152d having at its end an enlarged spring housing 152c attached to the case wall and have springs 152b mounted near their en~s. The springs 152b act in conjunction with the case wall ~ case wall orifice 94a and orifices 102a and 102c of vertical members 102. When handles ].51a and 152a are pulled together the ends of rods 151 and 152 are pulled out of the orifices permitting vertical members 102 to mov~. The springs 152b maintain tension so that when the .
vertical members 132 are fu11y extended, the ends ~f the locking rods 151 and 152 engage the orifices 102c thus locking the handle in the extended position. Orifices 102a lock handle when retracted.
, There is a separate m~chanism for each wheel 111 connected and actuated by the common wheeling handle lO0. The mechanism illustratcd in Flg. 2 is similar for each wheel. The vert1c-1 ;
. 5 member 102 comprises a U-shaped channel having cover plate 102b and transverse wall 102d having orifices or notches 102e and 102f Closed wire loop 133 is movable through orifices 102e and 102f so ~hat the outer portion of closed wire loop 103 acts as a los: motion upon extension of the handle. The combination of vertical member 10~ and wire loop 103 mo~e in a track 113. The ends of wire loop 103 are connected to both sides of a pin 104.
Pin 104 slides in slot 106 of wheei holde: 105 and also in the slot 107 of frame nlember 108. Frame member 108 is connected to wall 9S of the lug~age case. Wheel support is pivotally support-ed by fixed pivot lOSa mounted on luggage case frame member 108.
Wheel suppoft 105 also has a depending portion in which there is a pin llla ~.olding the wheel 111 and also a door stop portion 11?
Door stop 112 acts against spring-pivoted door 110, which door forms a portion of wall 97 of the case ir openi~g 97a.
Suitable cover plates 113a and 12C are provided to cover the track 113 so as to form a closed concuit for the motion of the mechanism.
The wire used in ma~ing wire 103 is preferably suitably tempered to maintain shape and yet have some flexibility. Where the mechanism illustrated in Figs. 1 to 4 is applied to a trunk the wire 103 or handle can be shorter since no lost motion would be required.
Although this invention is not limited to any particular sizej it is preferred ~hat for common sizes of l~,rge luggage that wheels of two to four inches in diameter be used. For a three-inch ~yheel t~e enclosure for the embodiment illustrated in Figs. 1 to 4 would be approximately four inches by three and a half inches. Roll~rs can be used in place of wheels, but wheels are preferred because of easier navigation particularly on rough surfaces.

Refe.ring now to the embodiment illustrated in Figs. 5 - B
the mechanisns are housed in a similar manner as in the ~`irst embodiment and the handle and locking are similar. The si~nifi-cant difference between this second embodiment an~ the fArst embodiment is in the door and lost motion aspects. Instt!ad of having a loop of wire providc all the lost motion with a swingingl door, this second embodiment has a sliding door 710 in space 197a ¦
in wall 197 Wit]l the lost motion for same provided by the curva-ture of the cam slot 207 in frame member 208 which is connected to case wall 195. Ihe wheeling handle 201 has a pair of U-shaped _ channels 202 sliding within track 213 and interlo-ked at wall 202 to wire loop 203. The other end of loop 203 is permanently con-nected to one end of the sliding door 210. Door 210 moves in track 213 and at its other end is permanently conlected by wire loop 203a to pin 204. Pin 204 extends through straight slot 206 of wheel support 205 and also through curved slot 207 of frame member 208. Wheel 211 is suspended on the lower portions of wheel holder 205 by pin 211a. Wheel support 205 is permanently connected by fixed pivot 205a to frame member 20U. Cover plates 213b and 213c are provided to form an enslosed conduit with the tracks 213 and 213a.
