Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luggage fixing device capable of immovably securing and stacking luggage in the trunk of an automobile.

[0002]

2. Description of the Related Art When luggage is loaded in a luggage compartment, particularly when small luggage is loaded with a gap left, the traveling speed changes like when the vehicle turns or starts or stops. If there is, there is a danger that the loaded luggage will move under the influence of inertial force in the luggage compartment, so-called luggage rampage. Then, there is a possibility that the loaded luggage may collide with each other, the luggage may collide with the inner wall of the luggage compartment, and an abnormal noise may be generated or the luggage may be broken.

[0003]

Conventionally, as the above-mentioned preventive measures, it has been practiced to bind the load with a string or to fix the load by packing a cushioning material in the gap. In addition to having to prepare a separate fixing member,
There was a drawback in that it was forced to perform a troublesome work for fixing. The present invention has been completed in view of the above points,
It is an object of the present invention to provide a device that can securely and easily fix luggage loaded in a luggage compartment.

[0004]

As a means for achieving the above object, the invention of claim 1 is stored in a trunk room of an automobile in a contracted state at all times, and is expanded and deformed by injecting air to cause the trunk room to move. It is characterized in that it is provided with an air bag for pressing the baggage against the inner surface to fix the baggage, and an air supply means connected to the air bag for supplying and discharging air to and from the air bag.

According to a second aspect of the invention, in the first aspect of the invention, the air supply means has an air supply source for supplying air to the air bag, and an electric circuit for driving the air supply source. Is provided with an operation switch for driving the air supply source and an opening / closing switch which is connected to the operation switch in series and is turned on when the trunk lid for opening / closing the trunk room is closed. However, it has a feature.

[0006]

According to the invention of claim 1, the air bag is in a contracted state when not in use, but when air is supplied to the air bag through the air supply means when the luggage is loaded in the trunk room, the air bag is It inflates and presses the luggage against the inside of the luggage compartment. According to the second aspect of the present invention, when the operation switch is operated, the air supply source is driven to supply air to the air bag on condition that the trunk lid is closed.

[0007]

That is, according to the first aspect of the invention, since the luggage is fixed by the air bag installed in the luggage compartment, the work for fixing is extremely simple. Moreover, since the air bag is normally in a contracted state, it does not interfere with the loading and unloading of luggage. According to the invention of claim 2, it is possible to surely avoid accidentally inflating the air bag when the trunk lid is in the open state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the drawings, reference numeral 1 denotes a trunk room provided on the rear side of the body of a passenger car, and a trunk lid 2 for covering the trunk room 1 is provided on the upper surface of the trunk room 1, and a hinge (not shown) is used as a center. It is configured to swing and open between a chain line position and a solid line position.

On the back surface of the trunk lid 2, an air bag 3 having a size covering substantially the entire surface thereof is provided. The air bag 3 is formed into a bag shape having an open upper surface with a highly elastic material such as rubber, and can be folded by expanding and contracting the bellows portion 4 on its peripheral surface in multiple stages. Has become. The open edge of the upper surface of this air bag 3
It is hermetically fixed to the back surface of the trunk lid 2.

Surface fasteners 6 are provided at the four corners of the lower surface of the air bag 3, respectively. On the other hand, on the back surface of the trunk lid 2, bendable mounting bands 8 are attached so as to correspond to the outer sides of the four corners of the air bag 3. Surface fasteners 6 of the air bag 3 and surface fasteners 9 that are attached to each other are provided. In addition, at the position on the rear side of the vehicle body on the lower surface of the air bag 3, the air vent valve 1 that can be opened and closed.
1 is provided.

A compressor 13 serving as an air supply source is installed in the back of the trunk room 1, and the tip of an air hose 15 drawn out from the discharge port 14 is provided above the peripheral surface of the air bag 3. Is connected to the supply port 16 provided. The air hose 15 is piped with an appropriate degree of slack so that the trunk lid 2 can be opened and closed.

The compressor 13 has a power source 18
A power supply line 19 drawn from (for example, an automobile battery) is connected, and in the middle of the power supply line 19,
An operation switch 20 for connecting or disconnecting the compressor 13 to or from the power supply 18 is provided, and the operation switch 20 is provided in a driver's cab (not shown). Further, an opening / closing switch 21 that is opened / closed in conjunction with opening / closing of the trunk lid 2 is provided in the power supply line 19 in series with the operation switch 20.

The amount of inflation and deformation of the air bag 3 required to hold down the loads a, that is, the amount of air that must be supplied to the air bag 3, varies depending on the size of the loads a loaded in the trunk room 1. Therefore, for example, a relief valve is provided at the discharge port 14 of the compressor 13, and when the air bag 3 expands enough to hold down the loaded cargo a and the discharge pressure of the air rises above a certain level, the discharged air is discharged. Measures are taken to prevent the air from being further supplied to the air bag 3 by being released from the relief valve to the outside. In addition, after a certain time has passed after the operation switch 20 was turned on, the operation switch 20 is automatically turned off to stop the operation of the compressor 13.

The present embodiment has the above-mentioned structure, and its operation will be described below. When the air bag 3 is not used, the air bag 3 is folded as shown in FIG. And the surface fasteners 6 at the four corners of the lower surface
Then, the surface fasteners 9 of the respective attachment bands 8 are pressed and adhered to each other, and the air bag 3 is stored in the folded state on the back surface of the trunk lid 2. As a result, when luggage is loaded without using the air bag 3, the inside of the luggage compartment 1 can be widely used, and since the air bag 3 does not hang down, it does not interfere with the loading and unloading of luggage.

When loading luggage using the air bag 3,
The luggage compartment 2 is loaded in the luggage compartment 1 by opening the luggage compartment lid 2 as shown by the chain line in FIG. Next, the air vent valve 11 of the air bag 3 is closed, the attached fasteners 6 and 9 are removed, and the trunk lid 2 is closed. At this time, the power supply line 1 to the compressor 13 is linked to it.
The open / close switch 21 of 9 is closed.

Subsequently, when the operation switch 20 is closed in the operator's cab, the compressor 13 is connected to the power source 18 to operate, and air is supplied into the air bag 3 through the air hose 15. When air is supplied, the bellows portion 4 expands and the air bag 3 swells, and the lower surface thereof enters between the luggage a and the luggage a or between the luggage a and the inner wall of the luggage compartment 1 as shown in FIG. Meanwhile, it is pressed against the upper surface of the luggage a. As a result, the loaded luggage a is elastically pressed against the bottom surface of the luggage compartment 1 by receiving the air pressure in the air bag 3. When the air bag 3 is inflated enough to hold down the load a, the air discharged from the compressor 13 is released from the relief valve to the outside, and when the set time elapses, the operation switch 20
Then, the compressor 13 is stopped and the air supply is stopped.

As described above, since the loaded baggage a is fixed by the air bag 3, even if an inertial force acts on the baggage a while the vehicle turns, or starts or stops, The luggage a is prevented from going wild in the luggage compartment 1.

Even if the operation switch 20 in the driver's cab is accidentally closed before the trunk lid 2 is closed, the open / close switch 21 provided on the power supply line 19 is open and the compressor 13 may operate. Therefore, the air bag 3 does not inflate.

When the luggage a is taken out, since the inflated air bag 3 escapes above the trunk room 1 when the trunk lid 2 is opened, the luggage a can be taken out as it is. Then, for the next use, the air bleeding valve 11 is opened and the air bag 3 is folded and stored while bleeding air.

As described above, according to this embodiment,
Since the luggage a is elastically and immovably fixed in the trunk room 1 by the inflated and deformed air bag 3, the luggage a may collide with each other, or the luggage a and the inner wall of the trunk room 1 may collide with each other and generate an abnormal noise. Prevented,
Also, the luggage a is prevented from being damaged. Moreover, the work of fixing the luggage a can be performed easily and surely because it is only necessary to operate the operation switch 20 in the cab without preparing a separate fixing member.

Further, since the compressor 13 can be operated only when the trunk lid 2 is closed, the air bag 3 may inadvertently inflate with the trunk lid 2 left open. To be prevented.

Besides, the present invention is not limited to the embodiments described by the above description and the drawings, and the following embodiments are also included in the technical scope of the present invention. (1) The air bag 3 is not limited to being installed on the back surface of the trunk lid 2, but may be installed on another place in the trunk room 1. (2) Further, the operation switch 20 may be installed at a place other than the cab.
