INVENTOR, BY @fw QQ,

United States Patent O 3,135,105 LUGGAGE CASE Leo Brody, 508 E. Bodley Ave., Memphis, Teun. Filed July 23, 1962, Ser. No. 211,690 6 Claims. (Cl. 7071) This invention relates to certain new and useful improvements in luggage cases, and particularly relates to closure means adapted for use with luggage cases for enhancing the utility and usability of such devices.

In prior luggage cases there has been a severe problem on account of exposed release mechanisms for latching devices intended to retain the luggage cases in closed condition. As is well known, in many of the transportation media which are presently in vogue, luggage is handled with a great deal of lack of care so that often the exposed release mechanisms on luggage cases are activated so as to effect release of the case and to effect opening thereof in an undesired manner, as for example in the luggage compartment of an airplane.

It is particularly desirable, therefore, that a luggage case be provided with closure means in which the release mechanism is centrally located and is shielded by the conventional handle of the luggage case by which it is normally moved from place to place. Prior devices have had their diiiiculties on account of these exposed release mechanisms, and the present device principally contemplates a luggage case in which the closure mechanism has its only operating device extending beyond the case arranged in the neighborhood of the conventional handle of vthe luggage case so as to be shielded thereby.

The principal object of the present invention is to provide a new and novel luggage case.

A further object of the invention is to provide a luggage case having a new and novel closure means incorporated therein.

A further object of the invention is to provide such l a luggage case in which the closure means are operated from a central control so as to elfect a latching of longitudinally displaced latch elements to hold the case in closed condition when latched.

Y A further object of the invention is to provide such a .device in which the closure means includes spring means adapted upon release of the latching means toV spring apart the portions of the luggage case so as to provide for ready access thereinto.

A further object of the invention is to provide such a device in which the latching means includes a separable xture of cooperating sections in which a lixed pair of vhooks are connected with one section of the ixture device which may also house and carry the spring means for the separation of the luggage case and the one X- ture section is mounted within the top of one part of the case adjacent its rim, and in which the other part of the luggage case may carry the other iixture section which includes shiftable latching means positioned and adapted to `engage with the xed hooks in order to effect the fixation of the case as desired; and p A further object of the invention is generally to improve the design, construction and eiiiciency of luggage `cases and of closure means associated therewith.

Referring now to the drawings in which the various parts are indicated by numerals, the present device comprises a luggage case 11 composed of

separable sections

12, 13, which are conventionally hinged together at the bottom (not shown) and which are provided with the closure means of the present invention at the top in order to hold in closed condition.

To one section 12 of the luggage case 11 is fixed an inner peripheral rim 14 which is provided with an elongated groove 15 extending coextensively with the rim; and the opposite section 13 of luggage case 11 is provided with a mating rim 17, rim 17 having a coextensive tongue 19 adapted to mate with groove 15 to provide a snug seal for the case when closed. Case 11 is provided with la suitable handle 21 which is substantially centrally located and preferably is pivotally connected to a housing 22 mounted on one of the rims, as the rim 17.

Attached to the

respective sections

12 and 13 of case 11 are the interengaging closure means of the present devioe comprising a pair of cooperating fixture sections. One section 23 is affixed to case section 12 adjacent rim 14, section 23 including a pair of extending hook-shaped catches 25 which project beyond the limits of case section 12 and of rim 14 so as to extend into the area 0f case section 13 when the case is closed. Each of catches 25 is provided with a iiat substantially straight edge 27 which faces toward rim 14 and is parallel to and spaced therefrom. The outer parts of each of catches 25 are provided with curved edge portions 29, curves 29 being adapted to effect guiding and steadying of the device during its movement in use so las to stabilize the position ot fixture section 23 and thereby of case section 12.

Intermediate its length fixture section 23 is provided with a chamber 31 Within which is housed a spring 33. Chamber 31 has an access opening 35 adjacent the edge of the fixture section to permit the limited entry of abutment means into engagement with the spring. Access opening 35 is adjacent to and immediately below rim 14 and is open toward the opposite case section 13. Mounted on case sections 13 and positioned for cooperative engagement with catch iixture section 23 is a latch fixture section 37, which is mounted adjacent to and wit-hin rim 17 of case section 13.

Latch section 37 includes a bottom plate 39 and a top plate 41 between which are shiftably mounted the latching elements of the lixture.` Substantially at the longitudinal center of latch section 37 an upstanding turnpost 43 is pivoted upon bottom plate 39, extends upwardly therefrom through top plate 41, and beyond and through rim 17 and housing 22, and upwardly beyond case section 13. To the upper end of post 43 a knob 45 is rigidly attached and available to effect rotation of the post as desired, the knob seating slidably rotatably on housing 22 between the extremities of handle 21.

Between

plates

39 and 41 of latch section 37, an irregularly shaped lobe 47 is fixed to turnpost 43 and rotatable therewith. Lobe 47, beyond turnpost 43, is provided with an abutment enlargement 49 which extends outwardly beyond case section 13 toward case section 12, and is positioned to enter access opening 35 when the case is in closed condition so as to abut against spring 33.

inwardly opposite from abutment 49, lobe 47 is extended in an ear 51, tothe innermost end of which, within latch section 37, is pivotally attached one end of` a link 53, asA by a pin 54. The link 53 is slidablyY and lirnitedly swingably mounted within latch section 37 between

plates

39 and 41.

At its distal end, link 53 is provided with an outwardly extending enlargement 55, which terminates in a latch 57 rigidly fixed to enlargement 55 of link 53, and having a latching surface 59l extending laterally therebeyond and adapted to mate with the edge 27 of one of the catches 25. It will be observed that the catches 25 and the latch 57 are disposed in substantially coplanar relationship, and that latching surface 59 is substantially parallel to rim 17 of case section 13. The link 53 is provided in its enlargement with a diagonally disposed slot 61, which is shiftably mounted upon a fixed pin 63 rigidly mounted in latch section 37 between the

plates

39 and 41.

Lobe 47, laterally outwardly away from post 43, is provided with an arcuately formed recess 65 which is adapted to receive a mating arcuate surface 67 of a lock member 69, which is rigidly connected to a lock post 71 ypivotally supported in latch section 37 and extending upwardly with a key-receiving notch 73 into communication with an opening 75, formed upwardly through the case section, its rim, and housing 22, for access by a removable key (not shown) for the purpose of rotating the lock post and thus the lock member as desired.

On the side of lobe 47 opposite to recess 65, and substantially in longitudinal alinement with turnpost 43, the lobe is provided with a tooth 77. Adjacent to tooth 77 a notch 79 is formed in lobe 47. In contact with lobe 47 is a follower lobe 81 which is pivoted as by a suitable pin 83 to latch fixture 37.

Follower'81 is extended inwardly with an ear 85 similar to ear 51 on lobe 47, and to ear 85 a link 87 is pivotally connected as by a pivot pin 88. At its opposite end, link 87 is provided with an enlargement S9 similar to the enlargement 55 of link 53, at the terminal of which is formed a latch 91 similar to latch 57 and adapted to engage with the other of catches 25. Latch 91 has a latching surface 93, which is substantiallyy parallel to rim 17 and is spaced inwardly therefrom and is coplanar with and adapted to engage with the straight edge 27 of the other catch 25.

Like. enlargement 55, enlargement 89 is provided with a diagonalledv slot 95 which rides upon a pin 97, the pin being iixed to latch iixture 37. It will be seen that slot 95 slants oppositely, but substantially equally, with slot 61.

Follower lobe 81 is provided with a tooth 99 positioned to mesh with notch 79 in lobe 47, and with a notch 101 adjacent to tooth 99 adapted to mesh with tooth 77 on lobe 47. At the opposite ends of latch iixture 37 are provided a pair of curved abutments 103 adapted to receive and snugly engage with the curved edges 29 of catches 25. In this manner the catches are steadied in their travel toward the latch section, and as a result case section 12 is alined with case section 13 for ready interengagement of -the tongue and groove of

rims

14, 17. Furthermore, this interengagement tends to aline the sections of the closure means for proper interengagement upon closing of the case 11.

Intermediate enlargements

55 and 89, latch section 37 is further provided with additional abutment plates 105, which a're disposed to lie in thepath of movement of the enlargements upon link retraction so as to assist in preventing overtravel and accordingly to prevent strain upon the

respective pins

63, 97, and also to engage with the upper edges of the

respective links

53, 87 to prevent misalinement of the links during shift under retraction or extension movements pursuant to the operation of the turning knob and of the lobes.

In addition, pivot pin 54 and pivot pin 88 respectively are extended into guides 107, formed in bottom plate 39 and being of an oval shape to guide and restrict the respective link movements to and from latched condition from and to unlatched condition. Additionally it will be seen that the disposition of lock member 69 lies in the path of the distal end of abutment 49 so that the lock member serves to limit and prevent overtravel of lobe 47 during movement toward unlatched condition.

In construction of a luggage case in accordance with the present invention the case 11 and its

sections

12, 13 are set up with

theirrnating rims

14, 17, and the

fixture sections

23, 37 are mounted respectively within the case sections and adjacent the respective rims. When so mounted the catches 25 of section 23 extend beyond the limits of rim 14, and the elements of latch section 37 are housed within section 13 with the exception that abutment portion 49 of lobe 47 extends beyond the extremity of rim 17 The fixtures are mounted so that catches 25 are alined with curved abutments 103 of latch section 37, and abutment portion 49 of lobe 47 is alined with access opening 35 of spring chamber 31.

With the fixtures so mounted spring 33 is not under compression and the links 87 are in retracted condition so that tooth 99 on follower lobe 81 is meshed with notch 79 on lobe 47 and tooth 77 on lobe 47 is meshed with notch 101 on the follower lobe. With the links thus retracted latches 57, 91 are drawn back from the ends of the lixture with the diagonalled slots 61, moved along the

pins

63, 97. It will be observed that this movement of the links swings the distal ends of the respective links and accordingly the latches carried thereby slightly outwardly on account of the diagonal disposition of the respective slots.

With the fixtures so mounted on the respective case sections the device is ready for use, and the case section 12 may be moved toward case section 13, catches 25 moving along the curved abutments 103 to seat within latch iixture 37, and lobe enlargement 49 protruding into opening 35 effecting compression of the spring 33. As the movement continues the pressure of spring 33 against enlargement 49 of lobe 47 forces a rotation of the lobe about its pivot on turnpost 43, the intermeshing of follower 81 with lobe 47 causing a similar reverse rotation of the follower, thus eifecting extension movement of the

respective links

53, 87, moving

latches

57, 91 toward catches 25 for engagement of the catch edges 27 by the latching edges 59, 93;

As this longitudinal movement takes place it will be observed that the respective latches are spaced slightly away from the catch surfaces to provide a greater facility of movement into engagement therewith. As the longitudinal movement is continued and completed, the

slots

61, 95 are moved relatively to their

respective pins

63, 97, swinging the distal ends of the respective latches inwardly relatively to the case section and more tightly engaging with the catches so as to pull the sections into proper tight relationship, with the rims in mating sealing engagement. With the fixtures thus latched the case is held in closed condition, and if it is desired to prevent manual dislodgment of this engagement, lock member 69 may then be rotated, moving its arcuate surface 67 into engagement with arcuate recess 65 of lobe 47, thus firmly holding the lobes against rotation and consequently against accidental movement to unlatched condition.

When it is desired to open the case, if it has been locked, the lock member is reversely rotated relieving the restraint of its arcuate surface 67 on the recess 65 of lobe 47. Knob 45 may then be rotated, effecting rotation of lobe 47 and consequently the rotation of lobe follower 81, retracting the links and moving the respective latches away from the catches. When the latch-catch relationship has been relieved, spring 33, bearing against abutment 49, urges and forces the case sections apart into open condition.
