The present invention relates to mechanisms for holding a vehicle hood in an open condition and, more particularly, to a vehicle hood locking mechanism engageable to maintain a vehicle hood in a raised condition until positively disengaged by a user to enable lowering of the hood.
Devices for supporting a vehicle hood in a raised condition are known. However, many such devices may be inadvertently disengaged by vibration or movements of a user while working under the hood. Disengagement of the device may permit the hood to fall toward a closed condition, possibly injuring the user.
In one aspect of the embodiments described herein, a vehicle hood locking mechanism includes a locking member including a helical portion structured to be insertable into a cavity formed in a vehicle hood. The helical portion is structured to be rotatable with respect to the hood so that contact between the hood and the helical portion during insertion of the helical portion into the cavity causes a rotation of the helical portion from a first rotational position to a second rotational position different from the first rotational position. The locking mechanism is also structured so that the helical portion is rotatable from the second rotational position back to the first rotational position when the helical portion becomes positioned inside the cavity.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments described herein and together with the description serve to explain principles of embodiments described herein.
Embodiments described herein relate to a vehicle hood locking mechanism including a helical portion structured to be insertable into a cavity formed in a vehicle hood. The helical portion is structured to be rotatable with respect to the hood so that contact between the hood and the helical portion during insertion of the helical portion into the cavity causes a rotation of the helical portion from a first rotational position to a second rotational position different from the first rotational position. The locking mechanism is structured so that the helical portion is rotatable from the second rotational position back to the first rotational position when the helical portion becomes positioned inside the cavity. When the helical portion rotates from the second rotational position back to the first rotational position, the helical portion is prevented from withdrawal from the hood cavity, thereby securing the helical portion within the hood cavity and securing the hood in a raised condition. To lower the hood, the helical portion may be rotated manually from the first rotational position to the second rotational position. While the helical portion resides in the second rotational position, the helical portion may be withdrawn from the cavity. This allows the hood locking mechanism to be rotated to a stowage position and permits the hood to be lowered.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. Unless otherwise noted, similar reference characters are used to describe similar features on separate elements and/or embodiments. Any of the components described herein may be formed from a material (or materials) suitable for the purpose(s) of the element as described herein.
In one or more arrangements, the hood locking mechanism 20 may include a locking member 22 having a helical portion 22a structured to be insertable into a cavity 19c formed in a vehicle hood between an exterior panel 19d of the hood 19a (i.e., a panel facing outwardly away from the vehicle 19) and an interior panel 19e of the hood 19a (a panel facing, for example, in a direction toward the engine compartment 19b of the vehicle 19). The helical portion 22a may be inserted into the cavity 19c through an opening 19f formed in the hood interior panel 19e.
As seen in
The helical portion 22a may have a central interior cavity 22f structured to receive a portion of a mounting member 26 (described below) therein, thereby enabling rotatable mounting of the helical portion 22a on the mounting member 26. The central cavity 22f may also be structured to receive a portion of a connecting portion 28 (described below) therein, to enable an actuator portion 30 (described below) to be rotatably coupled to the helical portion 22a using the connecting portion 28.
The hood locking mechanism 20 may further include an actuator portion 30 spaced apart from the helical portion 22a and coupled to the helical portion so as to rotate with the helical portion. The actuator portion 30 may have a central cavity 30a structured to receive a portion of the mounting member 26 therein, thereby enabling rotational mounting of the actuator portion 30 to the mounting member 26.
In one or more arrangements, the actuator portion 30 may be connected to the helical portion 22a by a hollow connecting portion 28. The connecting portion 28 may be formed integrally with the actuator portion 30 (for example, by molding) or the connecting portion may be formed separately from the actuator portion 30 and attached to the actuator portion. The connecting portion 28 may be attached to the helical portion 22a by any suitable method (for example, adhesive attachment). When rotationally coupled to the helical portion 22a by the connecting portion 28, the actuator portion 30 may be structured to enable a user to rotate the helical portion 22a between first and second rotational positions of the helical portion (as described below) by manual rotation of the actuator portion 30.
The helical portion 22a and other elements of the hood locking mechanism 20 may be rotatably mounted to the mounting member 26 using any suitable method. In one example, referring to
A spring member 32 may be coupled to the helical portion 22a and structured to exert a biasing force on the helical portion 22a tending to rotate the helical portion from the second rotational position to the first rotational position. In one or more arrangements, the spring member 32 may be a torsion spring member having a first free end connected to the mounting member 26 and a second free end attached to the actuator portion 30 so that a torsional force tending to rotate the helical portion 22a from the second rotational position to the first rotational position may be generated by rotating the helical portion 22a (using the actuator portion) from the first rotational position toward or to the second rotational position. In one or more arrangements, the helical portion 22a may be structured to automatically rotate from the second rotational position to the first rotational position responsive to the spring member biasing force, when the helical portion 22a becomes positioned inside the hood cavity 19c after insertion through the hood opening 19f.
The helical portion 22a may be rotatable about the mounting member 26 and with respect to the vehicle hood 19a so that contact between the hood 19a and the helical portion 22a during insertion of the helical portion 22a into the cavity 19c causes a rotation of the helical portion 22a from the first rotational position to a second rotational position different from the first rotational position. In addition, the locking mechanism 20 may be structured so that the helical portion 22a is rotatable from the second rotational position back to the first rotational position when the helical portion 22a becomes positioned inside the cavity 19c. In one or more arrangements, the helical portion may automatically rotate from the rotational position back to the first rotational position when the helical portion 22a becomes positioned inside the cavity 19c, due to a spring force exerted by the spring member 32 as described herein. The helical portion 22a is considered to be positioned inside the cavity 19c when the entire helical portion 22a resides inside the cavity (i.e., between the interior and exterior) following insertion into the cavity through opening 19f.
As seen in
As the helical portion 22a is gradually inserted into the cavity 19c through opening 19f, the edges of the non-rotating hood opening 19f may contact the sides of the helical portion 22a. Because the helical portion sides 22d, 22e wind helically along the length of the helical portion as previously described, this engagement between the sides of the hood opening 19f and the sides of the helical portion 22a produces a gradual rotation of the helical portion 22a (in direction R1 shown in
To withdraw the helical portion 22a from the hood cavity 19c, actuator portion 30 may be manually rotated (against the biasing force exerted by spring member 32) to the second rotational positon as shown in
