Description
Background of the Invention
1. Field of the Invention
This invention relates generally to an automotive vehicle of the type wherein at least a part of upper-half of a vehicle body is so configurated as to be detachable or foldable, and more particularly to a stoplight arrangement in an automotive vehicle of this type.
2. Description of the Prior Art
In order to signal the braking of a motor vehicle to following automotive vehicles as quickly as possible, a stoplight arrangement has been recently proposed in which stoplights are disposed, in addition to usual stoplights located at the vehicle body rear section, in a location higher than that of the usual stoplights, for example, on a rear windshield.
However, the following drawbacks have been encountered in such a stoplight arrangement in case of a motor vehicle of the type wherein not only a rear windshield but also at least a part of or whole a vehicle roof section including the rear windshield is detachable or foldable to form an opening at the upper-half of the vehicle body. In the vehicle where at least a part of or whole the vehicle roof section is detachable, the stoplights are unavoidably removed from the vehicle body when the vehicle roof section has been detached. In a vehicle where at least a part of or the whole of the vehicle roof section is foldable by means of a folding hood or the like, the stoplights are unavoidably covered with the folded hood when the roof section has been folded thereby making impossible to signal the braking of the vehicle to the succeeding vehicle.
To solve the above-mentioned drawbacks, it may be suggested to dispose the stoplights on a rear parcel shelf or inside the rear windshield. However, in this case, a relatively large-sized shade members are required to be disposed between the stoplights and the windshield to prevent the reflection of light from the stoplights on the surface of the windshield. This leads to disadvantages from economical viewpoint due to necessity of the shade members and from operational viewpoint due to the fact that the shade members narrow the rear sight of the vehicle.
Summary of the Invention
An automotive vehicle of the present invention is composed of a vehicle body comprising a movable roof section such as a detachable body shell or a folding hood, for covering an opening formed in the vehicle body. A first stoplight is installed on the movable roof section in a first position and capable of being lighted when the roof section is in position to close the opening. Additionally, a second stoplight is installed on the vehicle body in a second position and capable of being lighted when the roof section is moved to form the opening. The first and second positions are considerably separate from each other.
Accordingly, even in the automotive vehicle of the type having at least a part of or the whole of the upper-half of the vehicle body is openable, braking of the automotive can be immediately and clearly signalled to following automotive vehicles regardless of the covered or uncovered condition of the upper-half of the vehicle body.

Detailed Description of the Invention
Referring now to FIGS. 1 to 3 of the drawings, an embodiment of an automotive vehicle of the present invention is shown comprising a vehicle body 10 which includes a portion 10a formed with a rear end panel 10b. The vehicle body 10 further includes a movable roof section herein shown as a body shell 12 which is detachably installed to the vehicle body portion 10a. The body shell 12 is formed with a rear windshield 14, and a rear-most part 12a of a roof section 16. The body shell 12 is provided with a first stoplight 18 which is located in a first position P.sub.1 lying at the rear end section thereof. The first stoplight 18 in the first position P.sub.1 can be clearly seen from the rear of the vehicle. The body shell 12 can be detached as shown in FIG. 2 to form an opening 10c in the vehicle body 10. The opening 10c is defined by the periphery of the vehicle body portion 10a and located between the rear end panel 10b and a roll bar 20. The roll bar 20 forms part of the vehicle body proper 10a and also of the roof section 16 and serves as a reinforcement member in the event that the vehicle rolls. A bed or carrier 10d for goods is located inside the vehicle body proper 10a.
As shown in FIG. 2, a second stoplight 22 is installed to the inner surface of the roll bar 20 and located in a second position P.sub.2 in which the stoplight can be clearly seen from the rear of the vehicle upon the body shell 12 being detached to leave the opening 10c. The rear end panel 10b is provided at its upper periphery with a connector 24 through which an electric circuit 26 for lighting the first stoplight 18 in the body shell 12 can be formed.
The electric circuit 26 shown in FIG. 3 includes a selection switch 28 of the change-over type which functions to selectively connect an electric source or battery 30 to one of the first and second stoplights 18, 22 which are parallelly connected with each other. Each stoplight 18, 22 has two terminals one of which is connectable with the battery through the selection switch 28 and the other connected to a brake pedal operated switch 32. Accordingly, the selection switch 28 is in a position indicated by a broken line in FIG. 3 in case where the body shell 12 is installed to the vehicle body portion 10a as shown in FIG. 1 thereby lighting the first stoplight 18 upon depressing a brake pedal (not shown) to slow down or stop vehicle, whereas the selection switch 28 is in another position indicated by a solid line in FIG. 3 in case where the body shell 12 is detached from the vehicle body portion 10a as shown in FIG. 2 thereby lighting the second stoplight 22 upon depressing the brake pedal. It will be understood that the selection switch 28 may be automatically changed in accordance to the installation or detaching operation of the body shell 12, in which the selection switch 28 is so arranged as to be changeable in its position upon receiving the depression force applied from the side of the body shell 12 at the location of the connector 24 so that the second stoplight 22 is lightable as shown in FIG. 3 in the state where the body shell 12 is detached to release the depression force.
The manner of operation of the thus arranged vehicle will be discussed hereinafter.
When the body shell 12 is installed in position, the first stoplight 18 can be clearly seen from the rear of the vehicle as shown in FIG. 1. At this time, the second stoplight 22 is always switched OFF so as not to light even upon braking operation of the vehicle. Accordingly, a shade for the second stoplight is unnecessary. In contrast with this, when the body shell 12 is detached from the vehicle body portion 10a as shown in FIG. 2, the second stoplight 22 becomes clearly visible from the rear of the vehicle. At this time, since the first stoplight 18 has been removed together with the body shell 12, the appearance design of the vehicle body 10 is good.
Additionally, the change-over operation of the selection switch 28 of the electric circuit 26 is made automatically without requiring any manual operation. However, it will be understood that the change-over operation of the selection switch 28 may be made manually.
FIGS. 4 and 5 show another embodiment of the automotive vehicle of the present invention which is similar to the embodiment of FIGS. 1 to 3 with the exception that the movable roof section 16 is constituted of a folding hood 34. In this embodiment, an electric circuit for controllably lighting the first and second stoplights 18, 22 is similar to that shown in FIG. 3 and therefore is omitted for the purpose of simplicity of illustration.
As shown in FIG. 4, the first stoplight 18 is located in the first position P.sub.1 where the stoplight 18 can be clearly seen from the rear of the vehicle. The first position P.sub.1 lies in a so-called rear parcel, i.e., behind a rear seat 10e and in front of the rear windshield 14. Accordingly, the first stoplight 18 is so located as to be seen through the rear windshield 14 from the rear of the vehicle. In this connection, an arm 36 for supporting the first stoplight 18 is required to bring the first stoplight 18 near the rear windshield 14; however, the arm 36 is relatively short since it is not necessary that the first stoplight 18 cannot be seen from the rear when the hood 34 is folded as shown in FIG. 5. In this embodiment, the selection switch 28 of the electric circuit 26 for controllably lighting the first and second stoplights 18, 22 is installed to a front roof rail 38 with which a front end of the hood 34 is brought into press contact.
The second stoplight 22 is located in the second position P.sub.2 where the stoplight 22 can be clearly seen from the rear of the vehicle in the state where the hood 34 is folded as shown in FIG. 5. The second position P.sub.2 lies below the roll bar 20 same as in the embodiment of FIGS. 1 to 3. More specifically, the second stoplight 22 is installed on the lower surface of the roll bar 20. The configuration of the second stoplight 22 is the same as that in FIG. 2. As seen from FIG. 5, the first stoplight 18 is covered with the folded hood 34 and becomes out of sight in the state where the hood 34 is folded. It will be understood that the vehicle of this embodiment is so configurated that the rear seat 10e is exposed upon folding the hood 34.
In operation of the vehicle shown in FIGS. 4 and 5, a driver (not shown) manually operates the selection switch 28 to select the position indicated by the broken line in FIG. 3 in the state where the hood 34 is in position to form the roof section 16 as shown in FIG. 4. In this condition, the first stoplight 18 is lighted in response to braking operation of the vehicle, so that the lighted first stoplight 18 can be clearly seen from the rear of the vehicle. At this time, the second stoplight 22 is always switched OFF and therefore no particular measure for preventing leaking of light from the stoplight is necessary. Additionally, in this embodiment using the folding hood 34 as the roof section 16, an elastic action is made between the first stoplight 18 and the rear windshield 14, so that it is possible to locate the first stoplight 18 in contact with the rear windshield 14. This makes unnecessary to take any measure for preventing light leaking due to, for example, light reflection on the inner surface of the rear windshield 14.
In the state where the hood 34 is folded on a rear end section 10f of the vehicle body 10 as shown in FIG. 5, the first stoplight 18 is covered with the folded hood 34 and is out of sight while the second stoplight 22 installed to the roller bar 20 becomes clearly seen from the backward of the vehicle. Then, the driver manually operates the selection switch 28 to change the position of switch 28 into that indicated by the solid line FIG. 3, so that the second stoplight 22 can be lighted upon braking operation of the vehicle.
While the selection switch 28 in this embodiment has been described as being operated manually, it will be understood that the selection switch 28 may be automatically operated in response to extending or folding operation of the hood 34.
Although only two types of vehicles using the detachable body shell 12 and the folding hood 34 have been shown and described in the above, it will be understood that the principle of the present invention is applicable to all automotive vehicles of the types wherein a vehicle body is provided with a movable section to form an opening in the vehicle body, in which suitable stoplight arrangements can be designed in accordance with conditions where the movable section is located in open or closed positions.
Therefore, the first stoplight capable of lighting upon the movable section being located in closed position is not required to light when the movable section is moved to open position, and therefore no attention is necessary except for avoiding an obstruction of the first stoplight on cargo loading and unloading operation in this state. Similarly, the second stoplight capable of lighting upon the movable section being moved to open position is not required to light when the movable section is in closed position, and therefore no attention is necessary except for avoiding an obstruction of the second stoplight on cargo loading and unloading operation in this state. Thus, the stoplight arrangement of the present invention is greater in freedom of design thereby making possible a variety of designs applicable to wider uses taking account of the type of the movable section of the vehicle body, the design of appearance of the vehicle body and the like.
