Description
Background of the Invention
The present invention relates to a vehicle body structure, and more particularly to a lock device for preventing a package tray from being opened by an accupant of a passenger compartment.
In a vehicle in which a luggage compartment separate from a passenger compartment is not provided, such as a so-called two box car, a space defined behind rear seats is employed as a luggage compartment. In most of such vehicles, a package tray, which can be opened, is provided in a luggage compartment to conceal luggage located in the luggage compartment from the outside.
These vehicles are equipped with a hatch back door which can be opened. When a passenger loads or unloads luggage from the luggage compartment, a hatch back door is upwardly opened to permit loading or unloading of luggage. To easily load or unload luggage from the luggage compartment, a package tray is designed to have a rear end which is connected with a hatch back door by a rubber belt etc., and to tilt around its front axis when the hatch back door is opened. This tilt enables the luggage compartment through which luggage is loaded or unloaded to be opened.
Further, to enable the loading or unloading of luggage from the passenger compartment, some of the above-described vehicles have package trays which can tilt around their rear shafts.
In all the above-described vehicles, the luggage compartment communicates with the passenger compartment even when the hatch back door is closed and locked. Hence, luggage loaded in a luggage compartment can be stolen when a front or rear door is opened.
Summary of the Invention
The present invention was developed in view of the foregoing background and to overcome the foregoing drawbacks. It is accordingly an object of this invention to provide a vehicle body structure having a package tray in a luggage compartment which conceals luggage from the outside, and which locks the package tray onto the vehicle body, thereby preventing the package tray from being opened from the passenger compartment.
To attain the above objects, the vehicle body structure according to the present invention has a package tray provided in a luggage compartment defined behind a rear seat. The package tray is mounted on a vehicle body. A lock means is provided between the package tray and the vehicle body. The lock means fixes the package tray onto the vehicle body, thereby preventing communication between a passenger compartment and the luggage compartment. The package tray is locked by the lock means onto the vehicle body.

Detailed Description of the Preferred Embodiments
The present invention is described in detail with reference to the accompanying drawings which illustrate different embodiments of the present invention.
FIG. 1 shows a cross-sectional view illustrating a luggage compartment in which a lock device according to the first embodiment of the present invention is employed. A luggage compartment 12 is provided behind a seat back 10 of a rear seat. A package tray 14 is located in the luggage compartment 12 and is mounted on a bracket 16 which is fixed onto a vehicle body. The package tray 14 includes a pair of pins 18A and 18B at its front sides and rear sides, respectively. These pins 18A and 18B are supported by the bracket 16. The intermediate side portions of the package tray 14 between the front and rear pins 18A and 18B, are mounted on stepped portions 16A of the bracket 16.
A hatch back door 22 is mounted on a rear edge portion of a roof 24 such that the hatch back door 22 may be tilted around the rear edge portion of the roof 24. When the hatch back door 22 opens, an opening is defined above a bumper 100. A rear window 220 is connected with the rear edge of the package tray 14 by a cord 222. A stopper 26 is provided on an interior of the hatch back door 22. The stopper 26 is located above the top surface of the rear edge portion of the package tray 14 when the hatch back door 22 is closed.
In the vehicle shown in FIG. 1, the luggage is loaded or unloaded after the hatch back door 22 is opened. When the hatch back door 22 opens, the cord 222 lifts the rear edge of the package tray 14 and the package tray 14 moves according to the movement of the hatch back door 22 to be swung around the front pins 18A. Further, to lift the package tray 14 from a passenger compartment 13, a passenger lifts up the front edge of the package tray 14 and the package tray 14 is swung around the rear pins 18B. Hence, the passenger compartment 13 is in communication with the luggage compartment 12.
FIGS. 2 and 4 show a lock device according to a first embodiment of the present invention. One of the side edges of the bracket 16 is secured to the vehicle body. The stepped portion 16A is provided at another side edge of the bracket 16. A clamp 28 is fixed at the front portion of the stepped portion 16A. The clamp 28 has a concave portion 20 therein where the pin 18A is fitted and supported. The concave portion 20 has an upper aperture 28A which is positioned at a point under the top surface of the stepped portion 16A. The bottom surface of the package tray 14 contacts the stepped portion 16A, and hence the upper aperture 28A is positioned under the package tray 14. The clamp 28 is made of a plastic material which has resilient characteristics. The clamp 28 supports the pin 18A to be rotatable therein. The pin 18A is fixed onto the bottom surface of the package tray 14 at the front side edge portion through a fastener 30. When the package tray 14 is mounted on the stepped portion 16A, the pin 18A is provided at the position where it is separate from the bottom surface of the package tray 14. The pin 18A can be engaged with the clamp 28 when the bottom surface of the package tray 14 contacts the stepped portion 16A.
A ratch 32 is rotatably mounted on a side part of the stepped portion 16A of the bracket 16. The ratch 32 is positioned under the clamp 28. The ratch 32 is made of a sheet of metal, and is stamped out from a sheet of metal. The ratch 32 comprises a hook 34 which encircles almost half the periphery of the pin 18A when the hook 34 is rotated to lock the pin 18A, a lever 36, and a projection 40 on which oen end of a cantilever plate spring 38 contacts with its bias force.
When the ratch 32 is in the unlocked condition as shown in FIG. 3, the curved tip end of the plate spring 38 contacts a concave portion 41 of the ratch 32, and the hook 34 is separate away from the pin 18A. When a passenger lifts the package tray 14 from the passenger compartment 13, the package tray 14 is lifted in the direction indicated by the reference "A" in FIG. 3. When the lever 36 is rotated in the counterclockwise direction from the position shown in FIG. 3, the ratch 32 rotates and the plate spring 38 moves over the projection 40 to contact a left concave portion 42 as shown in FIG. 4. In this condition, the hook 34 oves to the side of the clamp 28. The tip end of the hook 34 moves to the side of the clamp 28 to close the aperture 28A. This prevents the pin 18A from separating from the clamp 28. In this arrangement, the package tray 14 is locked. Hence, a passenger in a passenger compartment 13 cannot open the package tray 14. When the lever 36 is rotated in the clockwise direction from the position shown in FIG. 4, the package tray 14 is unlocked as shown in FIG. 3.
In operation of the lock device according to the first embodiment, when the pin 18A is in the unlocked condition as shown in FIG. 3, the package tray 14 can rotate around the pin 18A or 18B. When a passenger opens the hatch back door 22, the package tray 14 is rotated around the pin 18A by the cord 222 connecting the hatch back door 22 with the package tray 14. Further, a passenger in a passenger compartment 13 can lift the package tray 14 so that it rotates around the pin 18B. Thus, when the package tray 14 is rotated around the pin 18A or 18B, the luggage compartment 12 is opened.
To lock the package tray 14, a passenger opens the hatch back door 22 thereby rotating the package tray 14 around the pin 18A to lift the package tray 14. Next, the passenger rotates the lever 36 in the counterclockwise direction from the position shown in FIG. 3 to the position shown in FIG. 4. Subsequently, the passenger closes the hatch back door 22 and the package tray 14 is returned to the closed position. In this condition, the package tray 14 cannot be rotated around the pin 18A, thus a passenger cannot open the package tray 14 from the passenger compartment 13. Further, if the hatch back door 22 is locked, the package tray 14 cannot be rotated around the pin 18B by means of the stopper 26, thereby completely locking the package tray 14.
FIGS. 5 to 7 show a lock device according to the second embodiment of the present invention. According to the second embodiment, the lock device is provided on a bracket 16 as in the first embodiment. A slider 42, having a shape similar to a rectangular parallelepiped, is disposed on a stepped portion 16B which is located in front of stepped portion 16A. The slider 42 has a guide member 44 therein which is connected with one end of a tension coil spring 46. The slider 42 is designed to slide freely on the stepped portion 16B by positioning the guide member 44 within the L-shaped guide hole 48.
When the lock device is unlocked, the guide member 44 of the slider 42 is positioned within an elongated hole 48A, and the guide member 44 contacts the end of the hole 48A as a result of the bias force of the tension coil spring 46. In this condition, the front end of the slider 42 is located at the position which is separate away from an aperture 28A of a clamp 28, as shown in FIG. 5. As shown in FIG. 7 by the line 50, when the slider 42 is moved rearwardly against the bias force of the coil spring 46, it can subsequently be moved toward another elongated hole 48B. When the guide member 44 of the slider 42 is positioned within the elongated hole 48B, the slider 42 forwardly slides on the stepped portion 16B from the bias force of the tension coil spring 46. As a result, the front end of the slider 42 moves into the position above the aperture 28A of the clamp 28, thereby closing the aperture 28A as shown in FIG. 6. Hence, the pin 18A is prevented from being removed from the clamp 28. This is a locked condition. If the slider 42 is moved in the opposite direction to that indicated by the line 50, the lock is released to be in the unlocked condition as shown in FIG. 5.
FIGS. 8 to 12 show a lock device according to the third embodiment of the present invention. According to the third embodiment, the lock device is provided on a package tray 14. In this third embodiment, a pin 18A, is fixed onto a housing 54. When the package tray 14 is mounted on a bracket 16, the pin 18A is positioned within the clamp 28.

A pair of connection rods 64 are provided between the rocker arm 62 and the lock pins 56. The rod 64 is connected with one end of the rocker arm 62 at one end thereof and with the lock pin 56 at another end thereof. The lever 60 is rotated by a passenger.
When the lock pin 56 is in the unlocked condition, most of the lock pin 56 is located within the housing 54, as shown in FIG. 11. When the lever 60 is rotated in the clockwise direction from the position shown in FIG. 10, the lock pin 56 protrudes from the housing 54 to be located under the bottom surface of the bracket 16 as shown in FIG. 12. In this condition, the pin 18A is prevented from being removed from the aperture 28A of the clamp 28. This is the locked condition. When the package tray 14 is in the locked condition, the package tray 14 cannot be rotated around the pin 18A. If the lever 60 is rotated in the counterclockwise direction from the position shown in FIG. 10, the package tray 14 is unlocked, and returns into the condition shown in FIG. 11.
FIG. 13 shows a lock device according to a fourth embodiment of the present invention. This fourth embodiment is a modified embodiment of the third embodiment. According to the fourth embodiment, a pair of lock pins 56 are provided within housings 56A each of which is located at a lateral end of the package tray 14. In FIG. 13, one of the housings 56A is shown. Each lock pin 56 is connected with a lever 66 which is perpendicular to the lock pin 56. The housing 56A has a L-shaped guide hole 68 in which the lever 66 is movably guided. When the lever 66 is positioned in a short hole 680 of the guide hole 68, the lock pin 56 is maintained within the housing 56A. When the lever 66 is positioned in the short hole 680, the lock pin 56 protrudes from the housing 56A by a small length. This is the unlocked position. When the lever 66 is positioned a the long hole 68 as shown in FIG. 13, the lock pin 56 protrudes to. This is the locked position.
FIGS. 14 and 15 show a lock device according to a fifth embodiment of the present invention. According to this fifth embodiment, the lock device is provided on a package tray 14, as in the fourth embodiment. A lock pin 70 has a general h-shaped form, and comprises a pin portion 70A and a guide portion 70B. The guide portion 70B of the lock pin 70 is fitted into a bracket 72 which is mounted on the package tray 14 at a position abutting against a holder 30B. The holder 30B mounts a pin 18A therein. The guide portion 70B of the lock pin 70 is guided by the bracket 72 such that the guide portion 70B can move in a direction almost parallel to the axial direction of the pin 18A.
When the lock pin 70 is in the unlocked condition, the lock pin 70 is located in the position indicated by the phantom line in FIG. 15. When the pin portion 70A of the lock pin 70 slides in the direction indicated by the numeral 74 shown in FIG. 15 from the position indicated by the phantom line in FIG. 15, the pin portion 70A is located in the position indicated by the solid line in FIG. 15. In this condition, the pin portion 70A of the lock pin 70 protrudes to the position which is under the bracket 16. This is the locked position. To unlock the package tray 14, the pin portion 70A slides in the direction opposite to the direction indicated by the numeral 74 in FIG. 15.
