Description
Background of the Invention
1. Field of the Invention
This invention relates to a structure for removably mounting a support rod for supporting, in an open position, an openable closure member such as hood, trunk lid or the like which is pivotally mounted to open and close the engine room, trunk room or the like of a motor vehicle.
2. Description of the Prior Art
In order to have a better understanding of the present invention, reference will first be made to FIGS. 1A, 1B and 1C of the accompanying drawings, which illustrate an example of the prior-art structure using a support rod 1 such as shown in FIG. 1A, the prior-art structure being shown as applied to the engine hood of a motor vehicle. In the illustrated conventional structure, the support rod 1 is constituted by a single metal rod-like body having the opposite ends thereof worked to be bent in a hook-like shape and in a crank-like shape as indicated at 1a and 1b respectively. In actual use of the support rod 1, the crank-shaped end 1a is disposed in engagement with a mounting aperture formed in a bracket provided on the upper margin of a radiator core support panel 4 which defined the front portion of the engine room, as shown in FIG. 1B, while the hook-shaped end 1b is detachably anchored at an aperture formed in a reinforcement panel 3 attached to the inner surface of the hood panel, as shown in FIG. 1C, thereby supporting the hood at its open position as desired.
However, the aforementioned prior-art structure is disadvantageous in that difficulties are experienced in an attempt to mount the end 1b of the support rod 1 in the aperture formed in the reinforcement panel 3 for the hood, due to the fact that the end portion 1b is configured in hook-like or C-like shape, as mentioned above, for the purpose of preventing the hood, which is supported in its open position by means of the support rod, from being removed from the support rod when the hood is blown by a gust. Another disadvantage of the prior-art structure is such that since the hook-like end portion 1b is brought into direct engagement with the mounting aperture of the reinforcement panel 3, it is very likely that when the mounting operation is carried out, the panel surface is scratched by the fore end 1b of the support rod 1 so that scars are left there which result in the formation of rust.
Summary of the Invention
Accordingly, it is an object of the present invention to provide a novel and improved structure for removably mounting a support rod for an openable closure member such as engine hood, trunk lid or the like of a motor vehicle, thereby eliminating the aforementioned disadvantages of the prior art.
Briefly stated, according to the present invention, a retainer member of a plastic material formed with an engagement aperture and a guide passage communicating therewith is provided on one or both of the ends of the support rod; an anchor member of a plastic material, which is adapted for engagement with the retainer member, is provided either on the vehicle's body or the openable closure member; and by virtue of the engagement between the retainer member and the anchor member, the support rod is detachably retained, at one end thereof, with respect to either the vehicle body or the openable closure member.
Other objects, features and advantages of the present invention will become apparent from the ensuing description taken in conjunction with the accompanying drawings.

Description of the Preferred Embodiments
Referring to FIGS. 2 to 4, there is shown the structure according to an embodiment of the present invention, wherein use is made of a support rod which is constituted by a substantially straight rod-like body of a plastic material, preferably a glass-fiber-reinforced plastic material, such as shown in FIG. 2A, and a retainer member 11 molded of a plastic material is mounted onto the fore end portion of the support rod 10, the retainer member being adapted for engagement with an anchor member which will be described hereinafter.
As will be seen in FIG. 2A, the retainer member 11 comprises a thumb-like portion 11a a hook-like portion 11b configured in an inverted U-shape, and a shank portion 11c which is integral with the portions 11a and 11b. In the retainer member 11, a guide passage 12 is defined between the thumb-like portion 11a and the hook-like portion 11b; an engagement aperture 13 is defined by the hook-like portion 11b; and an axial hole 14 is formed in the free end portion of the shank portion 11c. The guide passage 12 comprises a tapered entrance portion 12a opened at a side of the top portion of the retainer member, a substantially straight portion 12b extending from the entrance portion 12a in substantially parallel relationship with the support rod 10 when the retainer member 11 is attached to the support rod 10, and an inclined portion 12c extending in communication with the straight portion 12b and engagement aperture 13. In order to attach the retainer member 11 onto the support rod 10, the latter is inserted, at one end thereof, into the axial hole 14.
Referring to FIG. 3A, the anchor member is shown generally at 15, which comprises a resiliently deformable anchor leg 16 configured in arrowhead-like shape; and an anchor pin 17 adapted for engagement with the engagement aperture 13 of the retainer member 11. The anchor member 15 is attached to the reinforcement panel 3 mounted on the inner surface of the hood panel, with the anchor leg 16 thereof being disposed in engagement with the mounting aperture 18 formed in the reinforcement panel 3.
With the aforementioned structure of the present invention, when it is attempted to support the hood in its open position by means of the support rod, the anchor pin 17 of the anchor member 15, which has been mounted in the mounting aperture 18 of the panel 3, is simply brought into engagement with the engagement aperture 13 of the retainer member 11 mounted on the end of the support rod 10, through the guide passage 12 comprising the entrance portion 12a, straight portion 12b and inclined portion 12c, so that the end of the support rod 10 is engaged with the anchor member 15. It is to be particularly noted that even if the hood is blown by a gust, it is possible to prevent the anchor member 15 and retainer member 13 from being accidentally disengaged from each other, by virtue of the fact that the engagement between the anchor pin 17 of the anchor member 15 and the engagement aperture 13 of the retainer member 11 is effected through the guide passage 12 which meets the engagement aperture 13 at one side thereof.
Although it goes without saying that the foregoing structure of the present invention can be applied to the both ends of the support rod 10, it is possible that the present structure may be applied to one of the vehicle body-side and closure member-side ends of the support rod and that a retainer member which is different in construction from the above-described one, may be mounted on the other end of the support rod. It is also possible that an anchor member which is different in construction from the above-described one, may be mounted on the other end of the support rod. It is also possible that an anchor member which is different in construction from the aforementioned one may be mounted in the mounting aperture. Alternatively, it is possible that said other end of the support rod may be worked to be bent in a crank-like shape as in the prior art, and in such a case, the bent end may be engaged with a mounting aperture formed in a bracket provided on the panel.
Although in the foregoing embodiment, the support rod was made of a plastic material, it is possible that the support rod may be made of metal as in the prior art.
As mentioned above, according to the present invention, there is provided a structure wherein a retainer member made of a plastic material is provided on one or both or the ends of a support rod, the retainer member being provided with an engagement aperture and a guide passage meeting the engagement aperture at one side thereof, and an anchor member is mounted either on the body of a motor vehicle or the openable closure member thereof, the anchor member and retainer member being adapted for engagement with each other, thereby enabling the openable closure member to be supported at its open position by means of the support rod. As will be appreciated from the above discussion, with the present structure, it is possible to eliminate the necessity for the end or ends of the support rod to be subjected to bending work which requires a complex process and high accuracy as is the case with the prior art. Furthermore, the possibility is also precluded that when the support rod is attached or detached, the panel surface is scratched so that scars are left there which result in the formation of rust as is the case with the conventional structure. Another important advantage of the present invention is such that the possibility is precluded that the support rod is accidentally removed under the influence of an external force. More specifically, when the hood is blown by a gust, the support rod tends to fall clockwise as viewed in FIG. 4, for example, and as a result, the retainer member will be pressed, at the side remote from the thumb-like portion, against the anchor pin and finally have the top recess of the hook-like portion thereof disposed in engagement with the anchor pin so that accidental removal of the retainer member, or the support rod from the anchor member can most effectively be prevented.
Obviously, a plastic support rod is advantageous in that it is never heated, by the engine heat or the like, to such an elevated temperature that inconvenience is experienced in handling as is the case with a metal support rod.
While the present invention has been illustrated and described with respect to specific embodiments thereof, it is to be understood that the invention is by no means limited thereto but encompasses all changes and modifications which will become possible from the appended claims.
