[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for fixing a luggage loaded in a luggage compartment of an automobile or the like.
The present invention relates to a fixing structure for fixing a belt for fixing loaded luggage to a vehicle body.

[0002]

2. Description of the Related Art At present, in a car, especially a passenger car, a luggage storage structure is provided in each part of the car for the convenience of a driver and a passenger. However, it is impossible to provide a large number of storage spaces having a certain size or more in the limited space inside the vehicle. For example, luggage having a size equal to or larger than a first-aid kit is collectively thrown into a luggage compartment (trunk room in a passenger car). In most cases, it is loaded in a part of the space of the rear seat.

The above-mentioned loaded luggage is affected by sudden acceleration, sudden deceleration and sudden turning of the vehicle as it is, moves within the loading space due to its own inertia, and collides with the inner wall of the vehicle body and other luggage. Becomes Since such a state is not preferable, various structures for fixing luggage have been invented and adopted for the purpose of avoiding such a state. As an example of this, an elastic rubber string net is fixed to the trunk room floor, etc.,
2. Description of the Related Art There is known an apparatus capable of fixing a plurality of packages at a time by storing the packages therein. However, while this device has an advantage that a plurality of loads can be easily fixed, it is difficult to completely fix the loads due to the elasticity and looseness of the net. On the other hand, as a general method of firmly fixing a load loaded on an automobile to a vehicle body, an apparatus that holds a load using a belt fixed to an inner wall of the vehicle body is known.

An example of a structure for fixing the belt to a vehicle body is as follows.
This will be described below with reference to FIGS. In the drawing, 1 is a trim on the inner wall of a trunk room as a vehicle-body-side fixing portion, 2 is a belt, 3 is a plate, 4 is a screw hole, 5 is a screw, 6 is a washer, 7 is a boss hole, 8 is an insertion hole, and 9 is a joint. It is. The plate 3 is formed by bending a substantially rectangular metal flat plate at an appropriate angle at the center in the longitudinal direction, and one end thereof is raised from the trim 1 on the inner wall of the trunk room. At one end of the plate 3 on the side in contact with the trim, a round screw hole 4 for inserting a screw 5 is formed, and at the other end on the side floating above the trim, an elongated hole 8 for inserting the belt 2 is provided. I have. The belt 2 is folded back after being inserted through the long hole 8, and the leading end thereof is bonded by means of sewing or an adhesive at a joining portion 9 on the middle side of the belt 2 itself. On the other hand, screw holes 4 are
At the same time, the plate 3 is fixed to the vehicle body by screwing the tip of the screw 5 into a screw hole 7 formed in advance in the trim 1 forming the inner wall of the trunk room and screwing the tip of the screw 5.

As described above, a plurality of belts each having one end fixed to the inner wall of the trunk room are arranged around the luggage, and then fastened to each other by means such as a buckle (not shown). To the vehicle body.

[0006]

When the vehicle body behaves rapidly, decelerates, turns suddenly, etc., the load tends to move relative to the vehicle body due to inertia, and a strong tension acts on the belt 2. For this reason, the plate 3 must be firmly fixed to the trim 1 so that the plate 3 does not rattle even under the tension of the belt 2, and fixing the screw 5 to the trim 1 is an operation using a tool. In particular, it is preferable to attach a small item that is easily damaged, such as a belt, at the final stage of the manufacturing process.

[0007] In the prior art, the plate 3 is bent at an appropriate angle and lifted from the trim 1.
One end, the screw head of the screw 5 and the like make unevenness on the wall surface of the trim 1, and the appearance is extremely poor. There have been problems such as lack of stability of itself, and damage to luggage due to unevenness.

FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5, FIG. 6, FIG. 7, and FIG. 9, FIG.
This will be described with reference to FIG. In addition, about the structure which is the same as the conventional, each part is attached with the same code as the code used in the description of the conventional technology, and the explanation is omitted.

(Embodiment 1) FIGS. 1, 2, 3 and 4 show a belt fixing structure according to the present embodiment, and the structure will be described in detail below. A fixing device (hereinafter, referred to as a retainer 10) for fixing the belt 1 and the trim 1 on the inner wall of the automobile trunk room to each other includes a base portion 11 and two locking pieces 15. The base 11 has a substantially rectangular flat plate shape, and its side surface is inclined, so that the area of the front side 112 is larger than that of the back side 111. A long hole 12 penetrating from the front side 112 to the back side 111 is formed in the center of the base 11 in the major diameter direction, and its shape is set slightly larger than the cross section of the belt 1.
The two locking pieces 15 are arranged on the back side 111 so as to sandwich the long hole 12 in the minor diameter direction. Surface portions 17 opposing each other across the long hole 12 in the two locking pieces have a tapered shape that expands and expands toward the front end, and have a gap 18 therebetween.
In addition, about the surface part 17 formed in the taper shape, FIG.
As shown in FIG. 5, the surface is a smooth plane that is continuous from the inner surface of the long hole 12, but is not particularly limited. On the outer side of the surface portion 17, a substantially mountain-shaped locking portion 16 is protruded. With respect to the retainer 10, the trim 1 has a recess 31 which has the same shape as the base 11 and can be fitted therein. A locking hole 32 is formed in the bottom of the recess 31 so as to penetrate from the front to the back of the trim 1. I have. The shape of the locking hole 32 is a rectangle whose major axis direction is the same as that of the recess 31. The size of the locking hole 32 is such that the two locking pieces 15 are elastically deformed so as to pass through the belt 2 and pinch them. The size that the unit 16 can pass is set. In the fixed state,
The locking portion 16 that has passed through the locking hole 31 is locked to the back edge of the locking hole 32.

Next, the procedure and operation of the actual assembling operation of the belt 2 will be described in detail. First, belt 2 is
From the front side 112 into the long hole 12, the long hole 12, the void 1
8 to the back side 111. After the terminal of the belt 2 pulled out to the back side 111 is folded back several times, it is fixed by means of sewing or bonding to form a retaining portion 21. Since the size of the long hole 12 is originally set slightly larger than the cross section of the belt 2, the retaining portion 21 is
2, the belt 2 and the retainer 10 are fixed.
Next, the retainer 10 is inserted into the concave portion 31 and the locking hole 32 with the belt 2 pulled out to the back side 112 so that the retaining portion 21 is not located between the gaps 18 (see FIG. 2). The locking piece 15 has a locking hole 32 formed by the inclined surface of the substantially mountain-shaped locking portion 16.
And passes through the locking hole 32 while being elastically deformed so as to sandwich the belt 2 inside. When the locking portion 16 passes through the locking hole 32, the locking piece 15 is restored by elasticity, and the locking portion 16 is locked to the back side edge of the locking hole 32. In the above-mentioned locked state, the base 11 is fitted into the recess 31, and the front side 112 forms a smooth surface with the trim 1. With the above operation, the fixing of the belt 2 to the trim 1 is completed (see FIG. 3).

At the time of fixing the luggage, a plurality of belts 2 fixed to the trim 1 by the same fixing structure are arranged around the luggage and connected using a buckle or the like (not shown) to fasten and fix the luggage. At this time, the retaining portion 21 is pulled back to the gap 18 by the tension applied to the belt 2 and contacts the tapered surface portion 17. At this time, in order to prevent the end of the retaining portion 21 from being caught on the tip of the locking piece 15, it is desirable that the retaining portion 21 be firmly fixed to the end on the retainer 10 side. Further, when tension is applied, the retaining portion 21 presses the surface portion 17 to expand the locking piece 15 (see FIG. 4). At this time, in order to expand not only the distal end portion but also the entire locking piece 15, the position of the surface portion 17 pressed by the retaining portion 21 is desirably at the center of the surface portion 17, particularly the back side of the locking portion 16, but is particularly limited. Not something.

That is, even when the vehicle is accelerated or decelerated while the load is fixed and a tension is applied to the belt 2 due to the inertia of the load itself, a part of the tension causes the locking piece 15 to expand and lock. Since the belt 16 and the retainer 10 do not come off from the trim 2, the fixed state is maintained because the engagement by the portion 16 is strengthened. As described above, if the belt fixing structure of the present embodiment is adopted, only the retainer and the belt are fixed in advance, and the fixing to the trim can be performed only by inserting the retainer, no tools are required, and the number of parts is reduced. Less is needed. Further, even when tension is applied to the belt, the locking piece can be expanded by utilizing the tension, and a strong locking state can be maintained.
When the fixing of the belt is completed, the wall surface on the vehicle cabin side is flush, and a load not fixed to the belt is not damaged or is unstably loaded.

(Embodiment 2) In the present embodiment, the inner base 41, the elongated hole 42, and the locking portion 46 of the structure of the trim 1, the belt 2, and the structure relating to the retainer are the same as those of the first embodiment, and will be described. Omitted. The difference from the first embodiment is that the surface portions 47 of the locking pieces 45 are substantially parallel to each other, and the width of the formed gap 48 is substantially equal to the thickness of the retaining portion 21 (see FIG. 5).

Regarding the assembling work and operation of the belt 2,
The description of the same parts as in the first embodiment will be omitted, and only different points will be described in detail. After fixing the belt 2 and the retainer 40 in the same procedure as in the first embodiment, the retainer 40 is
2 (see FIG. 6). After the belt 2, the retainer 40, and the trim 1 are fixed to each other as described above, when the work for fixing the loaded luggage is performed, tension is applied to the belt 2 and the retaining portion 21 is drawn into the gap 48, and the retaining portion is pulled out. 21 is the surface 4
7 (see FIG. 7). The retaining portion 21 has a gap 48
Therefore, even if a strong tension is applied to the belt 2 and a force is applied in a direction in which the retainer 40 is pulled out, the inward elastic deformation of the locking piece 45 for passing through the locking hole 32 is prevented, and the fixed state is maintained. Will be retained.

The present embodiment has a unique effect that the workability can be improved over the first embodiment. This is different from the first embodiment in which the entire surface is tapered to form the expanding means. In this embodiment, the interval between the locking pieces at the distal end can be reduced, and the retainer can be inserted into the locking hole. This is because it is difficult to bring the tip of the locking piece into contact with the edge of the locking hole and the operation proceeds smoothly. The other effects are the same as those of the first embodiment.

(Embodiment 3) As shown in FIGS. 8 and 9, this embodiment presents an appropriate example when the arrangement of the locking holes 32 is located near the boundary between the bottom surface and the side surface of the trim 1. The difference from the second embodiment is that a part of the base 51 is cut off on the side that is in contact with the substantially vertical surface, and is locked on the vertical surface of the two locking pieces 55 of the locking pieces 551 and 552. Locking piece 55
The second locking portion 56 is made to approach the base portion 51, and the locking portion 56 is protruded from the side surface. Other configurations, work procedures, operations, and effects are the same as those of the second embodiment. Note that this case is a modification based on the second embodiment, but may be based on the first embodiment.

(Embodiment 4) As shown in FIGS. 10 and 11, this embodiment has a structure in which an inclined surface 69 is formed independently of a surface portion 67. The difference from the first embodiment in which the entire inner surface is expanded is that the interval between the locking pieces 65 at the distal end can be reduced, and the workability can be improved. Other configurations, operations, and effects are the same as those of the first embodiment.

The above embodiments all have a structure in which the belt and the retainer are fixed to the trim in the trunk room. However, the fixing destination is not limited to the inside of the trunk room. The same structure can be adopted for an exposed portion.
Further, in all of the above-described embodiments, the retaining portion is formed by folding the belt terminal. However, the retaining portion may be formed by fixing another member to the belt terminal.

[0023]

As described above, in the belt fixing structures according to the first and second aspects of the present invention, when the belt and the retainer are fixed to the vehicle body, it is only necessary to push the locking piece into the locking hole, and a tool is required. And not. In the first invention, the locking piece is pushed open by the tension applied to the belt itself, and in the second invention, the deformation of the locking piece is prevented by the interposition of the retaining portion, so that a strong locking state can be obtained. Further, according to the third aspect of the present invention, the vehicle cabin wall surface is flush, and unstable loading and damage of luggage can be prevented.
