The leaf spring also biases a detent ball into contact with a surface of the latch member for releasably maintaining the latch member in the open and closed positions.
Description
The invention relates to latching devices of the type including a rotatable latch member for use with luggage cases or the like, and is more particularly directed to improvements in latching devices of the type disclosed in Gehrie U.S. Pat. Nos. 3,020,742 and 3,020,743, granted Feb. 13, 1962.
U.S. Pat. Nos. 3,020,742 and 3,020,743, granted Feb. 13, 1962 to Gehrie, disclose latching devices for releasably fastening together separable parts of a container or the like. Each latching device includes a pivot bar adapted to be attached to one of the separable parts. A latch member is pivotally connected to the pivot bar for engaging a hasp mounted on the other of the separable parts when the longitudinal axis of the latching member is perpendicular to the axis of the pivot bar and for drawing the hasp toward the pivot bar when the latch member is rotated to a closed position wherein the longitudinal axis is parallel to the axis of the pivot bar. Each pivot bar includes an upstanding boss for engaging a locking bolt which is slidably supported by the latch member for locking the latch member in closed position. Detent means are also provided for releasably maintaining the latch member in either one of the open and closed positions. In the '742 device, the detent means comprises a plate attached to the latch member and having indentations thereon which are cooperable with a detent ball resiliently supported by a leaf spring in an opening in the pivot bar. In the '743 device, a bent wire spring is secured to the latch member and is cooperable with a pin projecting from the pivot bar to provide a detent action.
A primary object of the invention is to provide a latching device of simplified and improved construction, and wherein the number of operations required for assembling the parts is reduced, thereby minimizing the cost of manufacturing the improved latching device.
A further object of the invention is to provide a latching device wherein a single spring functions both to resiliently urge together the latch member and the frame or plate upon which it is mounted and to releasably maintain the latch member in respective open and closed positions.
A latching device made in accordance with the invention comprises a mounting plate having a projection thereon and a manually operable latch member supported by and pivotally connected to the projection for allowing the latch member to be rotated with respect thereto. A leaf spring biases the latch member into contact with the top surface of the projection. The projection includes stop means for limiting rotation of the latch member in a first direction to the closed position wherein the latch member substantially overlies the mounting plate and for limiting rotation of the latch member in the opposite direction to the open position wherein the latch member is substantially perpendicular to the mounting plate. The leaf spring also biases detent means into contact with the latch member for releasably maintaining the latch member in either the open or closed position.
In addition to the foregoing objects and advantages, other advantages and improved results will be apparent from the following detailed description of a preferred embodiment of the invention.

As shown in FIGS. 1 and 6, base 26 of frame B includes an opening 148 in which is positioned a ball 150. Leaf spring D includes an extended finger 152 which forces ball 150 against the underside of latch member C. Referring to FIGS. 6 and 9, when the latch member is in the closed position, ball 150 contacts latch member surface 113, which is shown in FIGS. 5 and 6 as one of the surfaces with which bolt cover plate 110 is engaged.
Similarly, when the latch member C is in the open position shown in FIG. 7, ball 150 contacts surface 114, which is shown in FIG. 5 as the other surface with which bolt cover plate 110 is engaged. However, as shown in FIG. 7, ball 150 rides on bolt cover plate 110 as the latch member C is rotated between the open and closed positions, thereby causing ball 150 to be displaced downwardly (with respect to its position when the latch member is either open or closed) by an amount equal to the thickness of the bolt cover plate. This downward movement of ball 150 is resiliently opposed by spring finger 152, which provides detent action for latch member C in the following manner. Referring to FIG. 9, when latch member C is in the closed position, ball 150 rests on surface 113 of latch member C and also resiliently contacts edge 154 of bolt cover plate 110, as shown in FIG. 6, for thereby maintaining side 70 of the latch member in contact with surface 92 on stop 90 of frame B. Similarly, when the latch member C is in the open position, shown in FIG. 7, ball 150 rests on surface 114 of the latch member and cooperates with edge 156 of bolt cover plate 110 for thereby maintaining side 72 of the latch member in contact with surface 94 on stop 90 of the frame. Rotation of latch member C out of the open or closed position requires that sufficient torque be applied thereto to move ball 150 against spring finger 152 a distance equal to the thickness of the bolt cover plate 110 to thereby enable the ball to ride on the bolt cover plate.
The manner in which the latching device A engages the hasp B and draws it into its latched position will now be described with reference to FIGS. 7, 8 and 9. In the position shown in FIG. 7, the boss 12 of hasp E may be moved between sides 70 and 72 of latch member C and toward surface 95 of the projection 28 of the frame B. When the boss 12 is in close proximity to surface 95 of projection 28, latch member C is rotated to effect latching, thereby causing side 70 of the latch member to engage boss 12, as shown in FIG. 8. As the latch member is further rotated, side 70 forces boss 12 generally in the direction of surface 95 of projection 28. However, if the boss 12 is not positioned directly opposite surface 95, surfaces 98 and 100 on projection 28 will direct the boss 12 to that position as side 70 of latch member C pulls the boss toward the frame B. When the latch member is in the closed position, shown in FIG. 9, the boss 12 will be held in the latched position by the side 70 of latch member C and by surfaces 95, 98 and 100 of projection 28 of frame B. The hasp is released by latching device A when the latch member C is rotated to the open position, as shown in FIG. 7.
As shown in FIGS. 1, 2 and 3, frame B may further include a portion 24 adapted for connection with a carrying handle. Handle connecting portion 24 includes a connecting post 50 around which a loop connected to the end of a carrying handle (not shown) may be connected. A connecting stud 51 projects downwardly from post 50 of frame B and is received by an opening 52 in projecting portion 46 and insert 48 of valance member 40 which is attached to suitcase section 42. An opening 53, which extends through stud 51 and into portion 24 of frame B, receives a screw 56 for securely mounting post 50 of the frame B on projecting portion 46 of valance member 40.
A washer 58 is secured against surfaces 60 and 62 of the handle connecting portion 24 by the action of decorative insert 48 of valance member 40 which abuts the bottom surface of washer 58 when the latching device A is connected to the valance member. As shown in FIGS. 2 and 3, the washer 58 cooperates with top portion 63, side portions 64, 65 and 66, and post 51 of handle connection portion 24 for providing a substantially enclosed housing for receiving the connecting loop of the handle (not shown) when the handle is not being used.
It is believed that the advantages and improved results furnished by the latching device of the invention will be apparent from the foregoing description of a preferred embodiment thereof. Various changes and modifications may be made without departing from the spirit or scope of the invention, as sought to be defined in the following claims.
