The present general inventive concept relates to a hood pin for securing an automobile hood and more specifically for a hood pin which includes an interrupter switch or other signal switch for indicating a condition of the hood pin.
Hood pins for securing vehicle hoods where the conventional latch system is either insufficient or not provided are known in the art. Numerous types of hood pins have been utilized, for example, on racing vehicles where the high speed of the vehicle can produce a substantial amount of lift forces on the hood, causing the hood to lift upward while the vehicle is in operation. Additionally, some aftermarket hoods, such as hoods designed for use with certain types of classic vehicles, street racing vehicles, and other types of vehicles, utilize hood pins rather than, or in addition to, conventional latch systems, for example to achieve a desired aesthetic and/or to provide additional security against lifting of the hood during operation.
While hood pins can be effective for securing a vehicle hood during operation of the vehicle, a problem arises in that, in certain circumstances, it is possible to inadvertently begin operating a vehicle without having the hood pin properly secured. This could occur, for example, at a car show, where multiple people may be opening and closing the hood to inspect the engine compartment and may close the hood without completely securing it by means of the hood pins. The driver or operator of the vehicle may assume the hood is secured because the hood is closed, without ascertaining whether the hood pins have been secured. In such circumstances, during subsequent operation of the vehicle, aerodynamic lift applied to the vehicle hood may result in the hood lifting upward, thereby obscuring visibility of the vehicle operator and creating an unsafe condition. Thus, it would be beneficial to have means available to indicate a condition of the hood pin, such as for example a condition in which the hood pin was not in properly secured to secure the hood against lift. In light of the above, there is a need for a hood pin which includes either a switch for producing a signal to alert a user of an “unlatched” condition of the hood pin, or an interrupter switch which serves to prevent the vehicle from operating prior to securing the hood.
The present general inventive concept, in various example embodiments, provides a pin or other member, at least indirectly attached to the vehicle hood, which moves under pressure by an operator, at least one electric switch, at least indirectly attached to the vehicle, to communicate signals to the vehicle, and in mechanical connection with the pin or other member, wherein movement of the pin or other member under pressure by the operator causes the hood to be secured to the vehicle and the electric switch to send a signal to the vehicle.
The present general inventive concept, in another example embodiment, provides a pin or other member, at least indirectly attached to the vehicle hood, which moves under pressure by an operator, at least one electric switch, at least indirectly attached to the vehicle, to communicate signals to the vehicle, and in mechanical connection with the pin or other member; an outer housing with at least two holes to accept a cotter pin or other self-locking device, at least one hole on the pin or other member that can mate with the holes on the outer housing, wherein the electric switch is attached to the housing to communicate signals to the vehicle, and is in mechanical connection with the pin or other member, and wherein mating the holes in the pin or other member with the holes in the outer housing and inserting the cotter pin or other self-locking device into the mated holes causes the hood to be secured to the vehicle, and the electric switch to send a signal to the vehicle.
The following example embodiments are representative of example techniques and structures designed to carry out the objects of the present general inventive concept, but the present general inventive concept is not limited to these example embodiments. In the accompanying drawings and illustrations, the sizes and relative sizes, shapes, and qualities of lines, entities, and regions may be exaggerated for clarity. A wide variety of additional embodiments will be more readily understood and appreciated through the following detailed description of the example embodiments, with reference to the accompanying drawings in which:
Reference will now be made to the example embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings and illustrations. The example embodiments are described herein in order to explain the present general inventive concept by referring to the figures. The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the structures and fabrication techniques described herein. Accordingly, various changes, modification, and equivalents of the structures and fabrication techniques described herein will be suggested to those of ordinary skill in the art. The progression of fabrication operations described are merely examples, however, and the sequence type of operations is not limited to that set forth herein and may be changed as is known in the art, with the exception of operations necessarily occurring in a certain order. Also, description of well-known functions and constructions may be omitted for increased clarity and conciseness.
Note that spatially relative terms, such as “up,” “down,” “right,” “left,” “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over or rotated, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
According to various example embodiments constructed in accordance with the present general inventive concept, a hood pin mechanism with a switch, such as for example an interrupter switch or other switch, is disclosed. The example embodiments described herein are described with reference to a hood pin mechanism, of the type having a low voltage ignition interrupter switch integrated in the pin housing. However, those skilled in the art will recognize that the present general inventive concept may be implemented using other types of switch devices, such as for example switches to activate one or more lights, noise signal devices, or other such devices. Furthermore, those skilled in the art will recognize that the present general inventive concept may be implemented using other types of interrupter switches other than ignition interrupter switches. For example, in other embodiments, a hood pin may be provided having an interrupter switch integrated therein which is configured to lockout various functions of the vehicle electronics, transmission, accelerator, or the like.
With reference to
As will be described in further detail below, an inner hood pin 30 is provided defining a generally cylindrical outer surface. More specifically, the inner hood pin 30 is sized and shaped to correspond generally to the inner surface of the outer housing 20, and the inner hood pin 30 is telescopically received within the outer housing 20, such that an upper end of the inner hood pin 30 protrudes from the end of the outer housing 20 proximate to the housing holes 24. The inner hood pin 30 rests inside the outer housing 20 and is coaxial with the outer housing 20. As will be described in detail below, the inner hood pin 30 moves telescopically in an axial direction relative to the outer housing 20. Also shown in
Shown in
Those skilled in the art will recognize numerous additional mechanisms and configurations by which the inner hood pin 30 may be permitted to move in an axial direction relative to the outer housing 20, while resisting or otherwise limiting relative movement of the inner hood pin 30 and the outer housing 20 in a circumferential direction; and such additional mechanisms and configurations may be employed without departing from the spirit and scope of the present general inventive concept. For example, in other embodiments (not shown), this relative movement of the inner hood pin 30 and outer housing 20 may be achieved, for example, via corresponding parallel flat areas defined along the inner hood pin 30 and outer housing 20, via provision of a slot and corresponding pin, or via a hex-shaped, square-shaped, or other appropriately shaped inner hood pin 30 received within a correspondingly-shaped opening defined by the outer housing 20. Additional suitable mechanisms and configurations will be understood and recognized by one of skill in the art.

In the illustrated embodiment, the interrupter switch 40 defines a cylindrical, threaded outer surface and is received within an interiorly-threaded cavity defined in a lower end of the outer housing 20. Electrical contacts 42 extend from beneath a lower end of the outer housing 20 and a switch button 44 extends generally upwardly, along a central axis of the inner hood pin 30, coaxial with the actuator bolt 70. In the illustrated embodiment, depression of the switch button 44 causes a voltage to form between the electrical contacts 42 and current to flow, sending an electric signal. Similarly, releasing the switch button 44 stops the signal. In this configuration, manual pressure by an operator on the upper portion of the inner hood pin 30 will cause the inner hood pin 30 to move toward the “depressed” position, telescopically inward from the outer housing 20, causing the through hole 32 and housing holes 24 to align, the actuator bolt 70 to move in an axially inward position, and the anvil 72 to depress the switch button 44, thereby sending the above-discussed electric signal indicating that the hood pin 10 has been moved toward the “depressed” position.
Operation of the hood pin mechanism 10, in one embodiment, can be described as follows, with reference to
Another embodiment constructed in accordance with the present general inventive concept is illustrated in
In operation, the outer housing 565 portion of the twist-style hood pin mechanism 510 is attached to a vehicle body as described above. When the twist-style hood pin mechanism 510 is received within the outer housing 565, the threads 522 on the inner hood pin 530 work cooperatively with the corresponding threads 550 within the outer housing, thereby securing the twist-style hood pin mechanism 510 to the vehicle. When the twist-style hood pin mechanism 510 is thereby secured in place, the actuator bolt head 572 makes contact with the switch button 544 attached to the interrupter switch 540, located within the outer housing. As with other embodiments described herein, the default position of the inner hood pin 530 is the “non-signal” position with the switch button 544 not depressed. Insertion and securement of the inner hood pin 530 within the outer housing 565 causes the actuator bolt 570 to be positioned toward the switch button 544 until the actuator bolt head 572 to depresses the switch button 544. Depression of the switch button 544 causes a voltage to form between electrical contacts 542 within the interrupter switch 540 and current to flow, sending an electric signal. Similarly, removal of the inner hood pin 530 from within the outer housing 565 causes the switch button 544 to be released, thereby stopping the signal.
Another embodiment constructed in accordance with several features of the present general inventive concept is illustrated generally in
In operation, when the latch 614 is moved from the illustrated open position to the closed position, the movement of the latch 614 drives the inner hood pin 630 such that the actuator head 672 is brought into contact with a switch button 644 attached to an interrupter switch 640. Additionally, when the latch 614 is moved from an open position to a closed position, the movement of the latch 614 causes a hook or other locking device (not shown) to engage with a rod or other device attached to the vehicle body, thereby securing the hood to the vehicle body. As with other embodiments described herein, the default position of the inner hood pin 630 is the “non-signal” position with the switch button 644 not depressed; this is the case when the latch 614 is in its open position, and the compression spring 660 assists in this function by resisting movement of the inner hood pin 630 toward the interrupter switch 640 and switch button 644. Pressure by an operator on the inner hood pin 630 causes the actuator head 672 to move and to depress the switch button 644. Depression of the switch button 644 causes a voltage to form within the interrupter switch 640 and current to flow, sending an electric signal. Similarly, releasing the switch button 644 stops the signal.
Another embodiment constructed in accordance with several features of the present general inventive concept is illustrated generally in
In operation, when the latch member 722 is moved from an open position to a closed position, the movement of the latch member 722 moves the actuator heads 772 so that the actuator heads 772 are brought into contact with corresponding switch buttons 744 attached to interrupter switches 740. Depression of the switch buttons 744 causes a voltage to form within the interrupter switches 740 and current to flow, sending an electric signal. Similarly, releasing the switch buttons 744 stops the signal. In the illustrated embodiment, a pair of interrupter switches 740 with switch heads 744 is provided, however, it will be recognized that any number of interrupter switches 740 with corresponding switch heads 744 may be provided without departing from the spirit and scope of the present general inventive concept.
