BAG FRAME END CATCH LOCK Filed Aug. 7, 1953 IN VENTOR ATTORNEYS United States Patent O BAG FRAME END CATCH LOCK Wallace E. Atkinson, Petersburg, Va., assigner to Long Manufacturing Company, inc., Petersburg, Va., a corporation of Virginia Application August 7, 1953, Serial No. 372,843

4 Claims. (Cl. 70-66) 'Ihe present invention relates in general to combined side catches and locks for the frames of travelling bags and similar articles of luggage, with special reference to bags having a pair of hinged channel frames.

Side catch locks of the types heretofore available on the commercial market for use with luggage having a pair of hinged channel frames to be secured together in confronting relation have generally been of rather complex construction and do not lend themselves readily to ease or economy of manufacture. Many of such locks require a spring loaded mechanism to open the catch, which is by its nature highly susceptible to jamming when the luggage is overpacked, which renders the lock subject to opening under the influence of a slight blow or jar, and which requires frequent servicing to keep the mechanism in proper working order. Further, the locl; components of such devices which receive the key and secure the catch usually are provided on the stationary portion of the device necessitating removal of the key before the movable portion carrying the catch can be shifted to unlocking position.

An object of the present invention is the provision of a novel side catch and lock mechanism for use with luggage which obviates the above mentioned disadvantages.

Another object of the present invention is the provision of a novel side catch and lock mechanism for use with hinged luggage frames, in which the movable parts have the appearance of substantial mass and depth, but wherein substantially all parts are composed of sheet metal shaped by ordinary stamping processes to insure uniformity and economy of manufacture.

Another object of the present invention is the provision of a novel side catch lock mechanism for luggage frames, which is highly dependable over a long period of use and in which the lock and associated components are integrated in a manner permitting the lock to be concealed in the movable portion of the mechanism.

Other objects, advantages and capabilities of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawing, showing only a preferred embodiment of the invention.

In the drawing:

Figure l is a fragmentary perspective view of a bag frame equipped with a side catch lock mechanism embodying the present invention;

Figure 2 is a longitudinal section view of the side catch lock mechanism, taken along the lines 2 2 of Figure l, and illustrating the same in closed condition;

Figure 3 is a sectional view taken along the lines 3*-3 of` Figure 2, showing the construction of the catch plate;

Figure 4 is a vertical transverse section view taken along the lines 4-4 of Figure 2;

Figure 5 is a longitudinal section similar to Figure 2 but illustrating the mechanism in open position; and

Figure 6 is a rear elevation of the side catch lock mechanism with parts broken away.

Referring to the drawing, wherein like reference characters designate corresponding parts throughout the several ice figures, the reference characters 10 and 11 designate the two channel shaped frame members of a suit case 12 or the like, which are hinged together at their ends in the usual manner. The combined side catch means and lock are generally indicated by the reference character 13, and comprise an elongated catch housing member 14 stamped from sheet metal and having a pair of clinching lugs 15 depending from its opposite ends. The lugs 15 are adapted to be passed through registering apertures in the outermost channel frame 10 and clenched over the underside of the channel frame member 10 to secure the catch housing 14 to the frame member. The catch housing 14 is formed with a top panel 16 bounded by downwardly depending side flanges 17 adapted to rest edgewise on the outermost frame member 10. The top panel 16 is provided with a central aperture bounded along one end thereof by a depressed portion 18 serving as an upper and lower limit stop for a catch tongue to be later described, and a pair of laterally spaced, rearwardly projecting ears 16' lying in the plane of the top panel 16.

The catch housing 14 serves as the support for the movable catch plate assembly 19 which comprises a catch plate cover 2l) preferably formed of sheet metal, having a top wall 2l bounded laterally by side walls 22 of substantial depth, the top wall 21 curving downwardly at one end, as indicated at 21' to the lower` edges of the side walls 22. The side walls 22 of the cover 20 are of sulcient height to give the cover the appearance of a block of considerable mass and are spaced laterally a suiicient distance to accommodate and overlie the side flanges 17 of the catch housing 14.

A catch plate 23 is disposed in nested relation within the catch plate cover 2t) and is carried thereby. The catch plate 23 comprises a plate member 24 having a downwardly curved portion 25 at one end to conform substantially to the curved portion 21' of the cover 20 and an upwardly curved formation 26 at the opposite end to bear against the outer end of the top cover panel 21, the top panel 21 being bent downwardly over the end 26, as indicated at 27, to secure that end of the catch plate 23 within the cover 20.

rhe downwardly curved end 25 of the plate 24 is provided with a pair of transversely aligned notches 25 in the edge thereot to accommodate the pair of spaced ears 16 projecting from the catch housing 14, and the lowermost edge or' the downwardly curved portion 25 is centrally notched to receive the lug 2S bent inwardly from the curved end 21 of the cover 2i) to secure the catch plate 23 within the cover.

A catch tongue 29 is xed to the catch plate 23 in downwardly projecting relation to extend through the aperture 16 in the top panel 16 of the catch housing 14 and be selectively projected through the aligned apertures 13', 11 or' the bag frames 16, 11 on pivotal movement of the catch plate assembly 19 about the ears 16 of the housing 14. A bowed leaf spring 30 having one end seated in a notch 29' at the back of the tongue 29 and its other end bearing against a lug 31 struck up from the top panel 16 of the catch housing 14 and bounding the rearmost end of the aperture 16, is provided to resilently urge the catch plate 23 upwardly and downwardly respectively when the end of the spring 30 seated in the notch 29 is disposed above and belowl a position substantially midway between the upper and lower limits of its travel. A shoulder 29a on the tongue 29 engages the limit stop depression 1S on the top panel 16 of the catch housing 14 to limit the upward travel of the catch plate assembly 19, and a shoulder 29b engages the stop 18 to limit downward travel.

A lock mechanism, generally indicated at 32 is provided in a housing 33 of generally shallow rectangular form having upstanding fastening lugs 33 bent over the Vedges ofthe catch plate 23 at therouter end thereof. The

lock mechanism 32 is preferably of the well known commercially available type comprising a lock tumbler bolt 34 `havin-gia recessed portion 34' lexposed below a circular keyreceiving aperture 24' in the plate 24 and a rotatable key barrel 35 mounted in the cover 20. The bolt 34 Vis slidable longitudinally under the influence of the operating bit of the key to selectively project the end of the bolt from the housing 32, and a resiliently biased member 36 cooperating with a-projecting'shoulder 34" on the bolt 34Yis provided to hold the bolt at the position to which itis shifted by the key.V Y will be apparent from they drawing, the lower face ofthe lock housing 33bears uponthe outermost portion Y of the top panel 1,6 of the catch housing 14 when the catch plate assembly 19 ris in downwardly pivoted position, and an upstruck keeper 37 is provided on the catch housing 14, vhaving a shoulder V38 to project over the end portion of the bolt 34 when the bolt is projected out- Y wardly of the lock housing 33 and lock the catch plate assembly 19 in closed condition.

In the use and operation of this form of combined side catch and lock', when the catch plate assembly 19 is swung to open position as illustrated in Figure 5, the lower end of the catch vtongue 29terminates above the plane between its llimits of travel, at which point'a downward resilient bias is exerted on the catch'tongue 29 and catch plate assembly 19 to bring the lock housing 33 into contact with the outermost portion of the top panel 16 of the lcatch housing 14. In this position, the catch tongue 29 Ais projected through the aligned apertures Vand I1 of the hinge channel members 10 and 11 when the channel Ymembers are in aligned relation to preventlateral dis- Y placementfof the channel members relative to each other.

Insertion of the operating bit of a key through the rotatable key barrel 35 in the cover 20 and the circular aperture 24' of the catch plate 23 and rotation of the key operating bit in a clockwise direction as viewed in Figure 3 brings the bit into the recessed portion 34 of the lock tumbler bolt *34. Further rotation of the key operating bit in the same direction forces the lock tumbler bolt 34. to the left as illustrated in Figure 3, the resiliently biased member 36 riding up over the projecting shoulder 34 and down the side of the Vsame nearest the recess 34' to hold the bolt in projected position cooperating with the keeper 37 to lock the catch plate assembly 19 in closed position.

Reverse rotation of the key in like manner cams 'the lock tumbler bolt 34 to the right as viewed in Figure 3 Vto withdraw the projecting portion of the bolt from operative association with the keeper 37, so that upward manual pressure may be Vexerted against the outwardly vpi'c.'jecting portion 27 Vof the catch plate assembly 19 to 'tilt the same upwardly to openV position, withdrawing the catch tongue 29 upwardly'throu'gh at least the aperture 1I" of the lowermost channel member 11.

While b'ut one particular embodiment of the invention yhas' been particularly shown and described, it is apparent Vtl'iat various modilications may be made in the invention without departing from the spirit and scope thereof, and it is desired, therefore, that only such limitations shall be placed thereon as are set forth in the appended claims.
