LUGGAGE LOCK Filed May 25, 1962 2 Sheets-Sheet 2 INVENTOR 6 CHARLE$ GEHR ATTORNEY United States Patent O 3,186,197 LUGGAGE LGCK Charles S. Gehrie, Montclair, NJ assignor, by mesne assignments, to Presto Lock (30., inc, Garfield, N..l., a corporation of New York Filed May 25, 1962, Ser. No. 197,739 9 (Ilaims. (Cl. fit-41) The present invention relates to devices that may be fastened to the companion parts of luggage for holding the luggage closed, and for locking the luggage.

An object of the invention resides in a novel form of luggage lock for companion luggage parts, the new and improved luggage lock being compact, reliable, rugged and attractive.

An additional object of the invention is to provide a new form of locking means for luggage that is operable positively in one stroke to hold the companion luggage parts together, and that is operable positively in a reverse stroke when the luggage is to be released.

Still another object of the invention resides in the provision of a novel slide-operated luggage lock in which the mechanism is enclosed, so that the luggage lock is both rugged and attractive in appearance.

A further object of the invention resides in the provision of a luggage lock of a novel form that is particularly well-suited to mounting on valance strips. It is common for valance strips to be secured along the edges of luggage parts to provide edge reinforcement and to provide overlap or tongue-and-groove mating of the edges.

A still further object of theinvention relates to an improved luggage lock that is self-indicating to show whether or not the hasp is engaged.

A further feature of the novel luggage lock is that it includes a hasp detent in the form of a cam that is effective to draw together the luggage parts and hold them tightly together.

The presently preferred embodiment of the invention is described in detail below and is shown in the accompanying drawings. In this embodiment, the lock includes an elongated tunnel member that contains a still longer slide body. One side of the tunnel member has an opening that admits a hasp carried by the companion luggage part. The slide body has a hasp-retaining detent that blocks the hasp-admitting opening in one position of the slide body. The hasp is locked in one position of the slide and the hasp is released by shifting the slide. The hasp-retaining slide projects from one end of the tunnel member in its locking position and the slide projects from the opposite end of the tunnel when the hasp is released. The slide can be positively operated into either position. This has the advantage of making the lock independent of operating springs and virtually immune to sticking of parts.

A key-operated locking bolt and a key-receiving barrel are carried in the slide body, near one end. The keyreceiving portion of the slide is shifted into the tunnel member when the slide is in its hasp-releasing condition. Consequently, exposure of the key-receiving part of the slide outside the tunnel member automatically provides assurance that the slide is in position to retain the hasp and hold the luggage closed.

The hasp-retaining detent carried by the slide is formed with a camming portion and a holding portion, and the hasp is rounded for cooperation With this detent. With this relationship, the detent and the hasp are effective to draw the two parts of the luggage tightly together, and to remain stably in this condition at the end of the stroke. To guard against any inadvertent release motion of the slide, the tunnel member and the slide member have coperating click-stop means that yieldingly retains the slide 3,186,195" Ratented June 1, 1965 in its hasp-locking position. The click-stop means also holds the slide in its hasp-admitting position.

A detailed description of the illustrative embodiment of the invention follows, in which reference is made to the accompanying drawings forming part of this disclosure. In the drawings:

FIG. 1 is a fragmentary perspective view of a pair of companion luggage parts, showing the illustrative luggage lock in its released configuration;

FIG. 2 is an enlarged bottom view of the luggage lock of FIG. 1, with the hasp showing in section in its released position;

FIG. 3 is a view of the luggage lock corresponding to FIG. 2, but with the hasp in its retained position effective to hold the luggage closed;

FIG. 4 is an exploded perspective view of the luggage lock of FIGS. 2 and 3, omitting the hasp;

FIG. 5 is a longitudinal cross-section of the illustrative luggage lock as viewed from the plane 55 in FIG. 2;

FIG. 6 is a transverse cross-section of the illustrative luggage lock as viewed from the plane 65 in FIG. 3; and

FIG. 7 is a fragmentary top plan view of a piece of luggage, showing a pair of the luggage locks in position holding the luggage closed.

In FIG. 1, the companion luggage parts it? and 12 have broad and narrow strengthening valance strips 14 and 16, respectively, along the confronting edges of those parts of the luggage. The valance strips are of complementary shapes so as to provide overlapped or tongueand-groove mating edges. A carrying handle 18 is secured to strip 14.

A hasp member 20 is fixed to luggage part 12, and has an upstanding hasp 22 that is circular as viewed from above. Integral rivets may be used to advantage for fix ing member 2% to luggage part 12. Such rivets 23 are shown in FIG. 6 before they are deformed in securing the hasp unit to the luggage.

Opposite the hasp on luggage part 10 is a luggage lock 24 that is fixed to the luggage part and has a bottom contour that is complementary to valance strip 14. One longitudinal edge of lock 24 projects beyond the edge of valance strip 14. Below luggage lock 24 and at the inside of luggare part lid, there is a bracket 26. The bracket extends outward beyond the edge of valance strip 14 and is aligned approximately with the overlying longitudinal edge of luggage lock 24. Valance strip .16 and hasp 22 enter the space between bracket 26 and lock 24 when the luggage is closed.

The construction of lock 24 is shown in FIGS. 2-6. Lock 24 includes a tunnel member 28 having an opening 30 in one side, and a pair of openings 32 at its opposite ends At its bottom, along one longitudinal edge, member 28 has a pair of integral rivets 34, shown in FIG. 6 as they appear before the lock is mounted. These rivets are to be set into holes through a luggage part and bracket 26, and flattened to fix the lock to the luggage. Depending at the center of tunnel member 28 is an internal boss 36 from which two integral rivets 38 project.

A composite slide body 40 (FIGS. 1 and 7) includes companion top and bottom sheet-

metal parts

42 and 44. These are keyed together by interengaging formations. These formations include tongues 46 (only one shown) that are received in the spaces outside off-sets 48, and downward bowed parts 50 that straddle legs 52 of 'the bridge section 54 of member 44. A pair of aligned

slots

56 and 58 in

members

42 and 44, respectively, flank boss 36 and are guided thereby for longitudinal sliding through a stroke that is limited by the relative lengths of the boss and the slots.

Rotatably mounted between

members

42 and 44 is a key barrel 60. A key may be inserted into the aligned key-receiving slots in member 42 and barrel 60, and rotated 360 to lock or unlock the slide member. Locking bolt 62 has an integral spring 64 that maintains one of two notches of the bolt in engagement with a locking lance 66 (FIGS. 2 and 3). When a key (not shown) is inserted and rotated in the proper direction, bolt 62 is lifted out of contact with lance 66 and shifted from either position in FIGS. 2 and 3 to the other. A locking projection 68 is operated between respective retracted and extended positions. In the latter position (FIG. 3) locking projection is received in a recess 7% in tunnel member 28, to arrest the slide body 49.

Member 42 has a laterally extending integral portion 72 disposed adjacent hasp-admitting opening 39 in tunnel member 28. At this point it may be mentioned, incidentally, that opening 30 as shown is longer than required, in order that the same tunnel member 28 may be used both for left-hand and right-hand installation at opposite ends of the piece of luggage as shown in FIG. 7.

Members

42 and 44 are also adaptable to such alternative installations. In any event, with portion 72 of the composite slide in one position (FIG. 2), a transverse path for admitting and removing a hasp is provided. In the opposite position of the slide body, portion 72 blocks the path through which hasp 22 must move to release the luggage. Notably, the key-barrel end of the slide is in a projecting position, clear of the tunnel, only in the hasp-retaining position of the composite slide. This gives clear indication outside the tunnel member 28 that the locking slide is in position to hold the luggage closed.

Portion 72 of the locking slide 49 has a cam part 72a that slants, relative to the direction of sliding, and it also has a rounded part 72b. During an operating stroke from the position in FIG. 2 to that in FIG. 3, cam part 72a engages a rounded surface of hasp 22 and urges the hasp downward in FIG. 2, applying force in the direction to tighten the luggage edges toward each other. The rounded part 72b moves into contact with round hasp 22 at the end of the stroke. The engagement is such that there is no tendency of upward hasp pressure to return the slide to its hasp-releasing position. Such upward hasp pressure would develop in the case of a tightly packed piece of luggage. Additional means is described below that further assures the retention of the slide in either its open or its locked position.

A longitudinally bowed spring 74 bears against the bottom of member 44, urging

members

44 and 42 upward against the inside top surface of tunnel member 28. This spring 74 is held in position by rivets 38. Upper member 42 of the composite slide member 40 has four raised nibs 76 that ride along the inside surface of member 28, thereby normally biasing the rest of member 42 downward and out of rubbing contact with tunnel member 28. Member 42 may thus be brightly finished without danger of being scratched during operation of the slide. At each extreme position of composite slide 40, the nibs 76 enter into correspondingly located recesses 78 on the underside of the tunnel member 28. Spring 74 presses the nibs into such recesses, and provides an audible click. This provision of click-stops holds the slide in either position in which it is left, so that the hasp-receiving opening 30 will be either entirely clear of the hasp detent 72 or the hasp will be blocked, without relying on a dead-center relationship of

parts

22 and 72a and without requiring use of locking bolt 68 to retain the slide member in its luggage-locking posi tion. When necessary or desirable, a key may be used to extend bolt 68 and positively lock the slide as previously described.

The mechanism for locking and releasing slide 40 is contained within tunnel member 28, making the luggage lock attractive and protecting the mechanism from tampering and accidental damage. Being a structure that is best made long, narrow and shallow, the disclosed luggage lock is well suited to use along valance strips at the edges of luggage parts. The described lock includes a keybarrel and locking bolt in the slide to engage the fixed tunnel. The luggage lock is in its hasp-retaining condition only when the key-receiving opening is in the part of the slide that projects clear of the tunnel member. This provides an automatic indication of the internal condition of the luggage lock.

The slide body is always accessible for direct manual pushing effort, to engage and to release the hasp. In this respect the present luggage lock is an improvement over catches that depend on catch-closing springs. The slide includes a cam part that applies a firm force drawing the luggage parts together. The cam part is shaped to remain stably in position at the end of its closing stroke; but to supplement this, and to hold the slide definitely in its open or its engaged position, a click-stop means is incorporated into the slide and the tunnel member assembly.

The foregoing illustrative embodiment of the invention has a number of related novel and important features, and is the presently preferred form of the invention. However, variation in detail, rearrangement and omission of some of these features will readily occur to those skilled in the art. Consequently the invention should be broadly construed in accordance with its full spirit and scope.
