Claims. (Cl. 16128.1)

This invention relates to hood latches for automotive vehicles, and has particular reference to those used on trucks and delivery cars where the hood lid is of the dual-tip variety, and is fastened and released by latches manually operable from the respective sides of the hood.

In hood latches of the kind to which the invention relates, it has been common practice in the past to have lid-securing or clamping devices adjacent the front and rear ends of the lid at each side of the vehicle, these devices being operable from handle members located about midway of the ends of the lid.

An object of the present invention is to simplify and decrease the cost of the latch mechanism by providing a lid-securing mechanism that gives very satisfactory service and in which the securing or clamping means is much simpler than heretofore and operates upon the lid intermediate of the ends of the lid and in close adjacency to the operating or handle member.

Another object is to provide an improved manually operable hood lid fastener which can be very success fully used in connection with hood lids of the dual-tip variety.

A further object is to provide a hood latch, of the general type above indicated, having improved operation characteristics, and especially one in which there are very effective provisions for inhibiting vibration and noise and looseness of the latch parts resulting from wear in service.

In the accompanying drawings:

Fig. 1 is a plan view showing the hood portion of an automobile equipped with hood latches embodying my improvements;

Fig. 2 is a section on line 2-2 of Fig. 1, an upwardly lifted position of the hood lid being indicated in broken lines;

Fig. 5 is a top plan view, with certain parts omitted, of the latch structure shown in Fig. 4, the released position of the latch being shown by broken lines;

Fig. 6 is an elevation, partly in section, of the latch mechanism shown in Figs. 4 and 5, looking from the inner side of the plate that carries the manipulating handle;

Fig. 7 is a section on line 7-7 of Fig. 6;

Fig. 8 is a vertical longitudinal section of the latch looking from the inner side of the plate that carries the manipulating handle, the latch being in the released position; and

Fig. 9 is a view generally similar to Fig. 4 showing the position of the parts when the lid has been lifted.

In the form of device selected for illustration, two latch devices embodying my improvements are shown, each being applied to the hood intermediate of the hood atent ends and serving to secure the lid at the side margin by action upon the hood lid and its intermediate part, the latching and releasing action of each device being effected by lateral swinging movement of a manual manipulating member or handle. In this form the manipulating handle, when the device is in the latched position, extends at one side longitudinally beyond the mounting plate so as to have a substantially horizontal position at one side of the lid, and as in this particular case it is desired to have the manipulating members stand rearwardly from the latch in the fastened position, as shown in Fig. 1, the two latch devices are of opposite hand. However, as the two devices shown are substantially identical so far as construction and operation are concerned, a description of one will suffice, the device shown in detail in the drawings being that appearing at the right of Fig. 2. Each of these hood latches is of the type used in a dual-tip lid structure in which the lid can be swung upwardly from either side, and can, if desired, be entirely removed from the engine enclosure. For this purpose each latch comprises in its structure a hinge in which a pintle or like pivot element hinges together two parts, one of which parts is secured in fixed position at the marginal part of the engine enclosure, and the other of which parts is a plate-like element adapted to be positioned substantially horizontally within the engine enclosure at the upper part thereof and is equipped with latch mechanism whereby it is adapted to be latched to and released from another plate-like member which is adapted to be mounted at the inner side of the hood lid and carries upon it a part of they latching mechanism and also a manipulating member or operating handle for the latch mechanism, which operating member or handle extends to the exterior of the hood lid and by swinging movement is adapted to fasten and release the latch. This last-mentioned platelike member in the form shown is generally of L shape, having an upright portion and a generally horizontal portion, the upright portion serving as a mounting for an upright detent shaft rigid with the swinging handle member and provided at the lower end with a swinging detent arm. This swinging detent arm is adapted to cooperate with a spring-pressed keeper member that is provided upon a portion of the first-mentioned latch plate in the manner hereinafter described.

In the drawings, the hood or engine-enclosing structure of an automobile is shown in Figs. 1, 2 and 3, and here the fixed part of the engine enclosure or hood is indicated. at 20 and the hood lid at 21, the hood lid being latched to and hingedly connected to the marginal portions of the engine enclosure at its respective sides by meansof latch devices, generally indicated at 22 and 23. In Figs. 3 to 9, inclusive, the detail structure of the latch device 23 is shown.

In the drawings, the part fastened to the marginal portion of the engine enclosure is indicated at 24, the hinge pintle is shown at 25, the plate-like part connected by pintle 25 to part 24 is indicated at 26, the L-shaped plate part of the latch mechanism is indicated at 27, the detent shaft at 28, the manipulating member rigid with shaft 28, at 29*, and the detent member at the lower end of shaft 28, at 30. The latch mechanism carried by plate 26, which cooperates with the detent member or arm 30, includes a keeper 31 that extends lengthwise of the mounting plate 26 and has pivotal connection to the plate 26 at one end of the keeper, as indicated at 32. A spring 33 mounted upon a pin 34 presses downwardly upon the free end portion of the keeper 31 so as to maintain it normally in the position shown in Fig. 8. In the latched position of the latch, the detent arm 30 is extended under the keeper 31 so as to have engagement with the upper wall of the keeper, as shown in Fig. 7, and in the released position of the latch the arm 3t) is withdrawn from the keeper and extends generally in the plane of the upright portion of the mounting plate 27. When the detent arm or bolt member is moved into and out of the latching position, it moves through a cut-out portion or aperture 35 which is provided in the detent-carrying plate structure.

Referring now more particularly to the details of the structure, the part 24 is preferably a relatively narrow strip or plate having means such as threaded holes 36 by which it can be rigidly secured in substantially horizontal position to the marginal part of the engine enclosure. Screws such as indicated at 37 engage the threaded holes 36, as shown, for example, in Fig. 4, and the plane of the plate 24 may be approximately vertical. Means such as leaf springs 38 may be fixed to the plate 26 in a position to abut against the strip 24 so as to hold the plate 26 normally in approximately horizontal position, as shown in Fig. 4 and Fig. 7. Near the hinge pintle 25 the plate 26 may have a U-shaped portion, indicated at 25 so as to clear the adjacent sheet metal work when the hood lid, is swung upwardly, as shown in Fig. 9. The U-shaped part 26 of plate 26 is integral with a portion 39, which in the position of Fig. 7 is substantially horizontal, and the plate 26 preferably has a transverse groove in the U- shaped portion 26 and in the flat portion 39 for the purpose of reinforcing the plate structure. The flat portion of the plate 26 may also have transverse grooves 40 formed in it adjacent the forward and rearward ends for the purpose of strengthening the plate structure.

At the inner end and at the middle part the plate portion 35 may be provided with a part ll (Fig. 7) in the nature of a tongue which is flat and projects inwardly past V-shaped portions 42, formed in the plate portion 39 at the respective sides of the part 41. The V-shaped portions 42, which are formed in the plate by bending the metal, provide valleys or V-shaped seats adapted to receive downturned lip portions provided upon the L- shaped mounting plate 27, as hereinafter described.

The keeper 3!, previously mentioned, is formed of a strip or bar of metal having an approximately horizontal upper portion integral with a downturned leg 43 at one end, which leg provides the pivotal connection 32 with the plate 26, as previously mentioned. For this purpose the leg 43 extends through a slot provided in the portion 39 of plate 26, and below the slot the leg is bent, as shown at 44, to hold the keeper in position, the arrangement being such that the keeper can have a limited amount of swinging movement in a vertical plane. Adjacent the opposite end of the keeper 31 the keeper is provided with a downturned leg 4-5 that is integral with a horizontal portion 46, and with an upturned tip or extremity 47. The pin 34, previously mentioned, has its lower end secured in place beneath the plate portion 39, and extends upwardly with clearance through a hole in the keeper portion 46, and the helical spring 33, which is confined between a head 34 on pin 34 and the keeper portion 46, normally holds the portion 46 against the plate portion 3%, as shown in Fig. 8.

For the purpose of guiding the mounting plate 27 with respect to the k eper, the mounting plate is provided in the horizontal portion thereof with upturned lugs 48, which lugs are located in the position of Fig. 8 adjacent the keeper leg :3 and the keeper tip 47, respectively, these lugs 4S facing each other across an open space that is a part of the cutway portion or aperture 35 previously mentioned.

The cut-away portion or aperture 35 is formed in part in the upright portion of the L-shaped plate 27, and in part in the horizontal portion, and it extends inwardly past the lugs 43. The inner part of plate 27 beyond the cutaway portion is in the form of an upwardly crowned bar 59 extending the full length of the plate and provided at the inner margin with downturned lips 59 that are adapted to engage in the valleys or seats provided by the V- shaped portions 4-2, as shown in Fig. 7, for the purpose of locating the plate 27 laterally with respect to the lower plate 26 and preventing relative displacement of the plates in a lateral direction. Between the lip portions 54 there is a cut-away portion 51 provided at the margin of the lower plate enabling the upper plate to accommodate the projecting tongue-like part 41 of the lower plate in a manner to locate the two plates relatively to each other in a longitudinal direction, and prevent relative displacement in such direction. Preferably those portions of the lips 5 which are adjacent the part 41 are slightly beveled in order to facilitate the seating of the upper plate on the lower plate.

The upper plate 27 is preferably made of a single member bent to provide the L-shaped form, and for strengthening purposes this member is preferably provided along both ends with integral flanges 52. The upright portion of the plate is provided with holes for the necessary fastening members by which the upper plate is secured to the side wall of the hood lid. The detent shaft 28, previously mentioned, is mounted in suitable bearings provided in the upright part of the plate 27. In the form shown, there is a lower bearing 53 provided upon the plate, which bearing is formed a metal portion bent outwardly from the plate, as shown in Fig. 7. The upper bearing 54 for the shaft is in this form provided by a similar outwardly bent portion of the plate. Between the upper and lower bearings the plate is provided with a longitudinal slot 55 through which extends a part of the operating structure for the shaft 28, which structure located in part outwardly of the plate and in part inwardly thereof. This operating structure includes the manipulating member 29, which in this form is provided with a horizontal bowed handle portion 55 that is integral with a shank member 57 that extends through the slot 55 and is integral with a rcversely turned portion 53 by means of which the handle is rigidly fastened to the shaft. in this form the portion 58 is provided With a hole through which the shaft extends, and the shaft is rigidly fastened to the portion 55 in a suitable manner as by means of a suitable fastening pin 59.

The manipulating member 29 also preferably includes as parts thereof suitable stop members which serve the purpose of arresting the manipulating member in the fully latched and fully released positions, respectively, and in this form the handle shanl; part 58, previously mentioned, has integral therewith a stop member oil and a second stop member 62. As will be noted from Fig. 5, the stop member 69 abuts the wall of the mounting plate when the latch is in the latched position, the point of engagement of member 6i) with the plate being forwardly of the slot 55, whereas in the completely released position the stop member 6i engages the plate rearwardly of the slot 55, as indicated by the broken lines in Fig. 5.

The portion 57 of the handle structure is preferably disposed on a curve concentric with the detent shaft, and, for the purpose of accommodating this portion and permitting its free movement, a sheet metal. part 62. of the hood lid, which is a masking portion overlying the detent shaft, is provided with an aperture such as indicated at 63 in Fig. 5.

The stop arrangement just described is of such character that the swing of the detent shaft is limited to approxi mately 90, the handle part of the manipulating member being substantially longitudinally disposed when the lid is in the secured position and being substantially transversely disposed with respect to the lid when the latch is fully released.

The detent arm 3%- is preferably provided by bending the lower end portion of the shaft 28 so as to provide a substantially horizontal detent arm. This arm is preferably provided at the extremity with a roller element 64, preferably in the form of a sleeve provided on the arm in such a manner that the sleeve is easily rotatable. This roller element is of a length substantially equal to the Width of the keeper 31.

As will be not-ed from Figs. 6 and 8, the upper approximately horizontal portion of the keeper bar or plate is sloped in a longitudinal direction to provide in such portion intermediate of the ends thereof a slight downward bulge in the nature of a transverse valley, as indicated at 65, and, as will be noted from Fig. 7, this part of the keeper is also bent downwardly in a transverse plane to provide a longitudinal valley, the result being that on the under surface of the keeper a blunt projection 66 is formed, the same being adapted to act as a cam cooperating with the underlying roller 64.

In the released position of the latch the roller 64 has the longitudinal position shown in Pig. 5 in dotted lines, and when the lid is lowered at the side in question the cut-away portion of the upper plate enables the generally horizontal portion of said plate to move over the keeper member, and the inner marginal portion of the upper plate engages the inner marginal portion of the lower plate in a manner to properly engage the upper plate with the lower plate. At this time there is a slight angle between the laterally extending portions of the respective plates somewhat greater than that shown in Fig. 7, and the engagement between the laterally extending portions of the plates takes place, as above stated, at their inner marginal portions. The detent arm being in the position above indicated, there is no interference with the described downward movement of the upper plate. The handle 56 is then moved in a counterclockwise direction with respect to Fig. 5, and this causes the detent arm to swing inwardly and to engage the upper part of the keeper bar and swing over the cam projection 66 totake the position shown in Fig. 6, which is the fully engaged position of the latch. In moving to this position the keeper bar is swung upwardly at its right-hand end (Fig. 6) against the action of the coil spring 33. After the detent passes the projection 66, it is very strongly held against a return movement, and the action of the latch is such as to lessen the angle between the plates and hold the lid very strongly in a closed position against the pressure of the spring.

The action caused by the turning of the detent arm is one of camming the lid downwardly at that side of the lid, moving the detent arm and therefore the lid in a downward direction against the action of the spring 33, which is compressed by the consequent upward movement of one end of the keeper bar. A result of this is that the lid is forced down and held down against spring pressure, and the spring, acting against a keeper that has a certain amount of free movement, takes up vibrations and shocks that would ordinarily be transmitted from the lower part of the hood structure to the hood lid. The pivotal or like connection between the keeper and the lower plate structure enables the keeper to have a certain amount of movement independently of the lower hood structure, and this movement is resisted by the spring. Furthermore, in the fully engaged position of the detent arm, as above described, there is very little surface contact between the detent arm and the keeper, and for this reason also there is less tendency to transmit vibrations from the lower part of the hood structure to the upper part.

It will be noted from Figs. 5 and 6 that in the fully latched position the detent arm is swung slightly forwardly of what may be termed the dead-center position, being at a small angle to a line at right angles to the axis of the keeper member.

In the action above referred to of camming the lid downwardly at one side for closing the lid, the upper and lower plates having their lateral portions at a slight angle to each other being pivotally related to each other because of the engagement of the marginal lips of the upper plate in the seats or valleys of the lower plate, the angle between the plates is decreased asa result of the pivotal movement of the upper plate. When the fully latched position has been reached, there is still an acute angle between the lateral portions of the two plates, as shown, for example, in Figs. 4 and 7.

It is to be understood that Figs. 4 and 7 show the condition at the right-hand side of the lid when the latch at the other side of the lid is fully latched, as shown in Fig. 2, that is to say, when the lid is subject to latching tension at both sides. At such time the lateral portions of the upper plates at the respective sides of the lid are somewhat lifted with respect to the lateral portions of the lower plate. When it is desired to release the lid at one side the manipulating handle at that side is turned in the proper direction and the lid is released by the disengagement of the detent arm from the keeper. As a consequence the keeper, under the influence of its spring, moves back to its normal position with respect to the lower plate. The lid is then free to be lifted at the side in question. When this lifting mov ment occurs, the hinge part of the latch at the opposite side of the lid comes into operation so that the lid swings upwardly to a position such as that indicated by the broken lines in Fig. 2. As respects the latch at the last-mentioned side of the lid, this will no longer have its lateral plate portions at an acute angle to each other, but will have them in substantially parallel abutting relation, as shown, for example, in Fig. 9, this being due to the fact that the previously referred to tension on the lid structure in a transverse direction has been removed. When the latch device at the respective side acts as a hinge to support the lid in a raised position, the keeper spring holds the free end of the keeper down against the upper surface of the lower plate.

It will be seen from the foregoing that in the improved hood latch the securing or clamping means operates upon the lid intermediate of its ends, and in close adjacency to the operating or handle member, and that as a result the mechanism is simplified and its cost decreased. it will be seen, also, that the latch is improved, as a result of the possibility of taking up, by spring action, looseness or play likely to cause vibration and noise. In the operativc position of the hood latch mechanism, the mounting plates have a relationship in which one plate can swing relatively to the other by a pivoting action, the pivot being provided by interfitting parts that do not cause objectionable noise or objectionable wear, and the pivotal movement of the plate serving to compress and release a spring acting upon a keeper member. The keeper member is free to move in a generally vertical plane with respect to the mounting plate which carries it, and the spring interposed between the mounting plate and the keeper allows considerable up-and-down movement relatively to each other of the two mounting plates without bringing the opposing face portions of the plates into contact with each other. These are all features which mark substantial improvement in a latch of this character, and among other things they provide effective means for taking up lost motion and reducing vibration, noise and wear.

The embodiment of the invention shown in the drawings is by way of example only, and various changes in the organization of parts and in the details may be made without departure from the principles of the invention or the scope of the claims.
