No. 46,967 8 Claims. Cl. 70-70) This invention relates to fastener devices which are well suited for use to releasably secure the hinged lid of a luggage case or other container in closed condition relative to the body of the case or container; this application being a continuation in part of my patent application Ser. No. 839,220, filed September 10, 1959, now abandoned.

An object of this invention is to provide a fastener device of symmetrical and preferably of oblongate shape and of low height in its closed condition, and of a type comprising a bolt means and a manipulatable latching member to receive the bolt means, said latching member operating in such manner that the same is actuated by swinging movements of a pivoted lever which forms an external overlying cover for said latching member.

Another object of this invention is to provide a construction such that the closing of the latching member relative to the received bolt means tends to draw the luggage or container body and its lid into tight fitting closed together relationship.

The manner in which these and other objects are attained according to the invention will be apparent from the following description of the invention taken with reference to the accompanying drawings wherein an illustrative embodiment of the invention is shown. This embodiment shown by said drawings is merely representative of the invention, the full scope of said invention being according to the claims appended hereto.

In said drawings, FIG. l is atop` plan view of a fastener device according to this invention and includ-- ing a bolt means and latching member shown in mutually engaged closed condition as mounted on the body and lidv of a luggage case or like container; FIG. 2 is a similar view showing the fastener device in open condition; FIG. 3 is a side elevational view of the open latching member, viewed in the direction of line 3 3 in FIG. 2; and FIG. 4 is a similar view of closed latching member, taken on line 4 4 in FIG. 1.

FIG. 5 is an enlarged plan view of the fastener device with the pivoted cover portion of the closed latching member shown in horizontal section, this view being drawn on an enlarged scale; FIG. 6 is a vertical longitudinal sectional view, taken on line 6 6 in FIG. 5; and

FIG. 7 is a transverse vertical 'sectional view, taken on the latching member, viewed in the direction of line 1 10 in FIG. 8.

FIG. 1l is a transverse vertical sectional view, taken on line 11-11 in FIG. 5, the bolt means being omitted.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

It will be understood that ordinarily the fastener devices of this invention are furnished and used in pairs, comprising a right hand fastener device and a left hand fastener device, respectively affixed to the luggage case or like container, usually is spaced away relative to the opposite ends of a carrying handle with which the case or container is provided. Since, structurally, said right and left fastener devices are similar, the showing of one thereof, as depicted in the accompanying drawings, is deemed to suce for both.

Referring now to said drawings, the fastener device' comprises a latching member 12 adapted to be aiiixed to the marginal edge portion of one of the separable parts of a luggage case or like container, such as the body 13v thereof, and a bolt means 14 adapted to be affixed the meeting marginal edge portion of the other of said separable parts of the luggage case or like container, such as the lid 15 thereof.

The latching member comprises an oblongate body. member or plate 16 of suitable length and Width, the same being secured in place on the case or container body 13 by suitable fastening means, such as rivet studs 17 dependent therefrom. Upstanding from the side marginal portions of the body member or plate 16 are side flanges or walls 18, the same being inwardly offset from the margins or edges of the body member or plate' 16, whereby to provide seating surfaces 19 engageable; by a pivoted cover member 20, when closed, and which forms a part of the latching member 12. This cover; member is of downwardly open hollow formation having' side walls 21, a rear end wall 22, and downwardly and' inwardly inclined forward wall 23; the latter providing. an undercut finger piece 24 by means of which the cover member can be manipulated, as and for the purposes: hereinafter described.

The cover member Ztl is pivotally connected by its rearend to the rear end of the body member or plate 16. The rear end portion of the body member or plate 16j is formed to provide a downwardly and outwardly in' clined beveled portion 25. The means for pivotally con-I necting the cover member 20 to the body member or plate 16 comprises a fulcrum lug 26 which upstands from said beveled portion 25 of the latter. Extending inward' ly from the rear end wall 22 of the cover member 20 isan inwardly and downwardly inclined transverse hinging` flange 27 having an opening through which said fulcrurnl lug 26 projects. Means hereinafter described is provided to retain the hinging elements 26 and 27 against separa-.- tion and displacement from their cooperative relation-: ship. The beveled portion 25 of the body member or; plate 16 as opposed to the inclined hinging flange 27 of the cover member 20 define a clearance recess 28 (see FIG. 4), which permits upswinging of the cover mem-f ber relative to the body member or plate from a closed; position shown in FIG. 4 to an open position shown-in; FIG. 3. y.

Intermediate the ends of the body member or plate '16,1 one of the side walls thereof is provided with an entrance-l way opening 29, through which a bolt tongue 30 of the bolt means 14 can enter the interior of the latching member 12 when the cover member 20 is upswung and the; separable parts of the case or container are closed together.

Slidably supported within the body member or plate. 16, in a horizontal plane parallel to the horizontal planef of said body member or plate, for longitudinal movements4T relative to the entranceway of opening 29,is a latch member comprising a guide arm 31, a tail portion 32 and a latch nosing 33. The guide arm 31 isslidably engagedz between the other or opposite side wall 18 of the bodyy member or plate and studs 34 which upstand from saidy body member or plate. Said guide arm 31 extends toward the hinge end of the latching member 12.

The forward or free end of the cover member 20 and. the latch member tail portion 32 are interconnected byv linkage means, so that movements of the latch member between engaging and disengaging positions relative to the bolt tongue 30 of the bolt means 14, when said bolt' tongue is entered in the latching member 12, canI be ef y fected by swinging movements of the cover member 20.

The linkage means comprises a link member having a transverse end bar 35 which is pivotally connected with the cover member 20 adjacent to the forward free end thereof. Such pivotal connection is provided by transversely :spaced bearing studs 36 which depend from the top wall of the cover member, and in connection with which the end Ibar 35 of the link member .is journaled. Upstanding from the body member or plate 16 is a transverse stopy boss 37 which limits retractive or releasing movement `o'l:` the latch member. The side arms 38 of the link member straddle this stop boss 37, and terminate in inturned trunnion-portions 39 which engage-in journaling notches 40 with which the sides of the tail portion 32 of the latch member is provided. lt will be understood, from an inspection of the drawings, that, when the pivoted cover member 20 is manually swung upward to Jopen position (see FIG. 3 and 8), the link member will exert a forward or retractive drag upon the latch member, whereby to withdraw its latch nosing 33 away from the entranceway opening 29 of the latching member 12, 'thus leaving `said entranceway opening unobstructed for entrance of the bolt tongue 30 of bolt means 14 with the latching member 12, or for withdrawal therefrom. When the pivoted cover member 20 is down swung from a'raised open position to-a closed position relative to the body .member or plate 16, the link member will exert rearward thrust upon the latch member, operative to engage the bolt tongue 30 of boit means 14 which has been :entered in the llatching member 12 (see FIGS. 5 and'7).

Preferably, spring means is provided to assist retracted releasing movement o'f the latch member. In the -novel io'rmand arrangement of such spring means as shown in the drawings, fthe same not only exerts retractive releasing thrust upon the latch member, but also serves as a means l'for locking the hinging elements 26 and 27 against separation lor displacement from their operative relationship. To these ends, the body member or plate 16 is lprovided with an vupstanding transverse spring mounting or positioning boss 41, which is located intermediate the hinge end of thelatching member 12 and the slidable latch member contained within Vits body member or plate 16. This boss 41 terminates short of the entranceway provided'side wall orange 18` of the body member or plate 16, whereby the bight vof a substantially U-shaped spring member 42 can be housed intermediate these parts (see FIGS. and'9). T'ne forward arm 43 `ol? this spring member yyieldably bears against the rearward end of the latch member guide arm 31. The rearward arm 44 of this spring member is anchored between the boss 41 and an abutment lug 45 which -upstands from the body member or plate 16 (again see FIGS. 5 and 9). Said rearward armv44 of the spring member-is provided with a rearwardly -bowed keeper section 46 which is Yadapted to overlie the hinging flange 27 of the cover member 20 after it is engaged with the fulcrum lug 26, thereby locking these hinging -parts against separation or relative displacement '('see FIGS. 6 and-8).

The movable latch member 31-32-33 and the Acooperative-spring member 42 are retained in operative relation'to the body member or plate 16 by an overlying cover plate 47, which is supported by the studs 34, stop boss 37 and spring mounting or positioning boss 41, and is afxed rto these parts by suitable fastening means, such as rivet elements 48 connected therewith. Said cover pla-te 47 has an end portion 49of reduced Width which is straddled by side arms 38 of the aforesaid link member.

The bolt means :14 desirably corresponds in length to that of the latching member 12, 4and said bolt means is adapted to be aixed to the lid 15 of a case or container by lsuitable fastening means, such as rivet studs 50 which are dependent therefrom. The bolt tongue 30 projects laterally from the body of the bolt means :14 in such location VAas to enter the latching member 12, when the body and lid of the case or container `are closed together.

It will be understood that the underside, of the latching member 12 and/ or the bolt means 14 may be shaped to conform to the contours of the marginal portions of the case or container body and its lid, as the case may be. For example, if such marginal portions include raised beading, as is sometimes the case, the undersides of the body mem-ber or plate 16 or of the bolt means 14, as the case may be, may be shaped to conform to and fit in overlying relation to such beading.

The bolt tongue 30 is shaped to provide a latching boss 51 which is adapted to be engaged by the latch nosing 33 of the latch member. This latching boss 51 is shaped to provide an inclined cam edge 52 that is adapted to be engaged by a correspondingly inclined cam edge 53 with which the latch nosing 33 of the latch member is provided. As the latch member is moved into engagement with the bolt tongue Sii, these engaging cam edges 52 and S3 will cooperate to draw inwardly the bolt tongue 36, and thereby will cause the body and lid of the case or container to be forced into tightly closed relationship.

As is disclosed in FIG. 6 of the drawings, the relationship between the pivotal connection of the link member 35-38-39 with the cover member 20 and the pivotal connection of said link member with the tail portion 32 of the latch member is such that, when the cover member is closed and the latch member is moved into holding engagement with the bolt tongue 30 of bolt means 14, the pivotal connection of the link member with the cover member will cross a dead center alignment with the pivotal connection of the link member with the latch member. By reason of this, and under the thrust of the spring member 42 as transmitted through the latch member and link member, the cover member 20 will be rni- 1y vheld against accidental displacement from its closed position, and can be opened only by countervailing manually 'applied lifting '-force. To permit such disposition of the pivotal connection of the link member with the cover member Ztl, the body member or plate 16 of the latching member 12 is cutaway, if necessary, to provide an opening or recess 54 giving clearance to receive the pivotal connection of the link member with the cover member when the latter is closed.

In most cases it is desirable to provide a key actuatable means for locking down the cover member 20 in closed position against releasing manipulation, when the bolt tongue 30 is engaged by the latch member to hold the separable parts of a case or container in closed condition, thus preventing unauthorized opening of said case or container. To this end, the 'cover member is provided adjacent to its forward free end with a -key actuatable lock bolt 55, which is slidably supported in a slideway formed between a ledge or shoulder 56 and the bearing studs 36 with which the cover member 20 is provided. Said lock bolt 55 is provided with key engageable projections 57, and with positioning notches 58 which cooperate with a stop nosing 59 with which one of the bearing studs 36 is provided. The lock bolt 55 has a spring arm 60 which exerts yieldable lateral thrust upon the same to effect cooperative engagement of the notches 58 with the stop nosing 59. A suitably shaped cover plate 61 is secured to and bridges between said bearing studs 36 and ledge or shoulder 56, whereby to overlie the lock bolt 55, and thus hold the latter in its slideway. This cover plate 61 is also provided with keeper projections 62 to overlie the end bar 35' of the link member, whereby toretain-the latter in pivotal connection with the bearing studs 36 of the cover member 2t). The cover member 20 is provided with a key barrel 63 rotatably mounted in its top wall, and so located as to admit a key (not shown) for engagement with the actuating projections '57 of the lock bolt 55. A side wall or ange 13 of the body member or plate 16 of the latching member 12 is provided with a locking boss 64 having a lock bolt receiving notch 65 which is opposed to the lock bolt (see FIG. ll). It will be obvious that, when the lock bolt 55 is advanced by key actuation, said lock bolt will be caused to enter the notch 65 of the locking boss 64, and thus the closed cover member 20 will be locked down against lifting or opening manipulation, until the lock bolt is withdrawn by reverse key actuation.
