Description

The present invention relates to a structure for fixing items to be carried in a vehicle compartment.

The following Patent Document 1 discloses a wheelchair fixing device as an example of this type of transport object fixing structure. This wheelchair fixing device is for fixing a wheelchair brought into the vehicle compartment, and is equipped with a locking belt that extends so that it can be pulled out and pulled back from the floor of the vehicle compartment. With this wheelchair fixing device, when the wheelchair is in a waiting state before being brought into the vehicle compartment, the hook of the locking belt is exposed to the floor surface. When the wheelchair is brought into the vehicle compartment, the user first grasps and pulls the hook of the locking belt, thereby pulling the locking belt out from the floor. The user then hooks the hook of the locking belt onto the wheelchair to tether it. This allows the wheelchair to be fixed to the vehicle compartment.

Japanese Patent Application Publication No. 11-113966

In the case of the wheelchair fixing device described above, the hook of the fastening belt is placed directly on the floor surface in the standby state, so the hook needs to be pulled up from the floor surface before hooking onto the wheelchair, which can be a burden for the user when fixing the wheelchair. Furthermore, if the fastening belt extends along the floor surface of the vehicle compartment, the user may step on the fastening belt, which can hinder smooth fixing of the wheelchair. Such problems can occur not only when fixing a wheelchair to the vehicle compartment, but also when fixing items other than the wheelchair to the vehicle compartment.

The present invention was made in consideration of these problems, and aims to provide an item fixing structure that is easy to use when fixing items inside the vehicle compartment.

One aspect of the present invention is
A structure for fixing an object to be carried in a vehicle compartment,
A fastening belt extending from a floor portion of the vehicle compartment;
An engagement portion provided on the fastening belt so as to be capable of engaging with the load;
a temporary holding portion provided on an interior material facing the vehicle interior so as to be capable of temporarily holding the engagement portion;
Equipped with
The temporary holding portion is provided at a position higher than the floor portion ,
The engaging portion has a hook,
the temporary holding portion has a loop capable of hooking the hook of the engagement portion,
the temporary holding portion is configured to weaken the holding force of the hook by the loop when the hook of the engagement portion is hooked on the loop and receives a tensile load exceeding a specified value ;
is located.

In the above-described structure for fixing an object to be brought in, the fastening belt extending from the floor of the vehicle compartment is provided with an engaging portion that can engage with the object to be brought in. This engaging portion can be held by a temporary holding portion provided on the interior material facing the vehicle compartment. That is, the engaging portion can be set to an engaged state with the object to be brought in, while the engaging portion can also be set to a temporary holding state by the temporary holding portion. When the engaging portion is in a temporary holding state, the fastening belt provided with this engaging portion is temporarily held on the interior material side. On the other hand, when the engaging portion is in an engaged state, the fastening belt is connected to the object to be brought in via this engaging portion, so that the object to be brought in is fixed to the vehicle compartment.

Here, since the temporary holding portion is provided at a higher position than the floor portion, when the engagement portion is in a temporary holding state, the fastening belt can be temporarily held in a state where it is raised above the floor surface of the vehicle interior. This eliminates the need to pull the engagement portion upward from the floor surface when engaging the item to be brought in, and makes it possible to grasp and operate the engagement portion in a position where it is easy to see. As a result, the workload when fixing the item to be brought in can be kept low. Furthermore, a structure in which the temporary holding portion is provided at a higher position than the floor portion is effective in preventing the user from accidentally stepping on the fastening belt, and is effective in facilitating the work of fixing the item to be brought in.

As described above, the above-mentioned aspect provides an item fixing structure that is easy to use when fixing items to be brought into the vehicle compartment.

1 is a perspective view of a vehicle interior configuration of an object fixing structure according to a first embodiment, viewed obliquely from above and behind; FIG. 2 is a cross-sectional view taken along line II-II in FIG. 3 is a cross-sectional view showing a state in which the detachable portion of the temporary holder in FIG. 2 is in a detached state; FIG. FIG. 2 is a plan view showing a standby state of the load object fixing structure of FIG. 1 ; FIG. 2 is a plan view showing a schematic view of the loaded object fixing structure of FIG. 1 in a loaded object fixing state;

Preferred embodiments of the above aspects are described below.

In the above-described embodiment of the load fixing structure, the temporary holding portion is preferably provided in an operable position that allows a user to grasp the engagement portion from outside the vehicle through the load opening into the vehicle compartment to temporarily hold the load.

With this structure for securing the carried-in item, the temporary holding part is in an operable position, so the user can grasp the engagement part and temporarily hold the item in the temporary holding part or remove it from the temporary holding part by performing operations within reach from outside the vehicle. This eliminates or reduces the effort required for the user to enter the vehicle interior when securing the carried-in item.

In the above-described embodiment of the load fixing structure, it is preferable that the engagement portion has a hook, and the temporary holding portion has a loop onto which the hook of the engagement portion can be hooked.

This structure for securing the loaded item makes it possible to temporarily hold the engaging part by the simple act of hooking the hook of the engaging part onto the loop of the temporary holding part.

In the above-described embodiment of the load fixing structure, the temporary holding portion is preferably configured to weaken the holding force of the hook by the loop when the hook of the engagement portion is hooked on the loop and receives a tensile load exceeding a specified value.

With this structure for securing carried-in items, when the hook of the engagement part is hooked on the loop of the temporary holding part and a tensile load greater than expected acts on the loop, the holding force of the hook by the loop is weakened. Therefore, for example, even when the user gets into the vehicle and interferes with the fastening belt, increasing the tensile load acting on the loop via the hook, the loop weakens the holding force of the hook, preventing the user from losing their balance or falling over.

In the above-described structure for fixing an object to be carried in, it is preferable that the temporary holding portion is provided with a mounting portion to which the mounted component is detachably attached.

With this structure for fixing the loaded object, the temporary holding portion used to temporarily hold the engagement portion can also be used to detachably attach the mounted component.

Below, specific examples of embodiments of the load fixing structure are described with reference to the drawings.

In the drawings used to explain this embodiment, unless otherwise specified, the arrow FR indicates the front of the vehicle, the arrow UP indicates the top of the vehicle, and the arrow IN indicates the inside of the vehicle.

(Embodiment 1)
1, the transport object fixing structure 101 of the first embodiment is for fixing an object W to a vehicle interior 2 of a vehicle 1. The vehicle 1 is a vehicle having a back door (not shown) that can open and close the vehicle interior 2, and opening the back door makes it possible to transport an object W into the vehicle interior 2 through a transport opening 8. The vehicle interior 2 is a space that mainly accommodates luggage and is also called a "luggage compartment."

The load fixing structure 101 generally comprises two fastening belts 10, an engagement portion 20, and a temporary holding portion 30.

The item W to be brought has an engaged portion (hereinafter referred to as "engaged portion Wa") such as a loop onto which the hook 21 of the engagement portion 20, described below, can be hooked. As long as the item W has an engaged portion, there are no particular limitations on its shape, size, number, etc. Examples of the item W to be brought include a wheelchair with a user in it, or a standalone wheelchair. In addition, the item W can be any of a variety of items to be brought into the vehicle compartment 2 and loaded onto it.

Both of the fastening belts 10 extend from the floor 3 of the vehicle interior 2. Each fastening belt 10 is configured as a long, flexible webbing member. The floor 3 houses a belt drive device 4 for each fastening belt 10. The right belt drive device 4 is used for the first fastening belt 10A, and the left belt drive device 4 is used for the other second fastening belt 10B.

The belt drive device 4 is equipped with an actuator (not shown) and is configured so that the actuator is driven to allow the fastening belt 10 to be pulled out and retracted. The belt drive device 4 allows the length of the fastening belt 10 pulled out from the floor 3 to be adjusted, and also allows the fastening belt 10 to be locked at any pulled-out position.

Note that, although two fastening belts 10 (first fastening belt 10A and second fastening belt 10B) are shown in FIG. 1, the number of fastening belts 10 is not particularly limited. When multiple fastening belts 10 are provided, it is preferable to provide the same number of belt drive devices 4 as the multiple fastening belts 10.

The engagement portion 20 is provided at one end of the fastening belt 10 opposite the belt drive device 4. This engagement portion 20 has a hook 21 and is configured to be able to engage with the load W at this hook 21.

The temporary holding portion 30 is provided on the interior material 5 facing the vehicle interior 2. This temporary holding portion 30 is configured to be able to temporarily hold the engagement portion 20. In this embodiment, the interior material 5 is a deck side trim that constitutes the vehicle interior 2. The interior material 5 has two mounting holes ("mounting holes 5a" described below) provided at positions spaced apart in the vehicle length direction. The interior material 5 also has a storage space 7 for storing the vehicle item A.

The temporary holding portion 30 is provided at a higher position than the floor portion 3 (higher than the floor surface of the vehicle interior 2). The temporary holding portion 30 is also provided at an operable position P where a user can grasp the hook 21 of the engagement portion 20 with their fingers and temporarily hold it through the loading opening 8 of the vehicle 1 from outside the vehicle. Typically, the operable position P can be a position within the reach of an adult of average build through the loading opening 8. This allows the user to temporarily hold the hook 21 from outside the vehicle without getting into the vehicle interior 2.

As shown in FIG. 2, the temporary holding portion 30 has a first belt 31 and a second belt 32, both of which are flexible webbing members, similar to the fastening belt 10.

One end 31a of the first belt 31 is attached to one of the mounting holes 5a of the interior material 5 by a clip 6, and the other end 31b is detachably joined to one end 32a of the second belt 32 via a detachable portion 36. As a result, the first belt 31 is in a tensioned state extending in the vehicle length direction, with the vehicle width direction being the thickness direction and the vehicle length direction being the width direction. At this time, the first belt 31 is configured to form either an attached state in which the other end 31b is attached to one end 32a of the second belt 32, or a detached state in which the other end 31b is peeled off from the one end 32a. Note that instead of this configuration, the other end 31b of the first belt 31 and one end 32a of the second belt 32 may be sewn together.

The second belt 32 is folded back at the intermediate portion 32c between the one end 32a and the other end 32b. The intermediate portion 32c of the second belt 32 is attached to the other mounting hole 5a of the interior material 5 by the clip 6, and the one end 32a and the other end 32b are detachably joined via the detachable portion 33. At this time, the second belt 32 is configured to form either an attached state in which the other end 32b is attached to the one end 32a, or a detached state in which the other end 32b is peeled off from the one end 32a. The detachable portion 33 is configured so that its joining force is lower than the joining force at the detachable portion 36. Therefore, when the detachable portion 33 receives an external load and the joining of the one end 32a and the other end 32b of the second belt 32 is released, the joining state between the other end 31b of the first belt 31 and the one end 32a of the second belt 32 is maintained at the detachable portion 36.

Here, the detachable parts 33, 36 are made of hook-and-loop fasteners known as "Velcro tapes." Hook-and-loop fasteners are of a known structure and are not shown in the figures, but they are tapes that can be attached or detached freely using a pile structure. Small mushroom-shaped expanders (hook-shaped hooks for hook-type) are arranged on one side, and loop shapes are arranged on the other side. When these two sides are attached together, the mushrooms (or hooks) get caught (entangled) in the loops, so that they are easily attached and attached. On the other hand, when these two sides are pulled together, the mushrooms (or hooks) come loose from the entanglement, and they are peeled off from each other and detached.

The second belt 32 has a loop 34 that forms a space 34a into which the hook 21 of the engagement part 20 can be hooked when the other end 32b is attached to the one end 32a via the detachable part 33. The loop 34 forms a loop shape in a position facing the vehicle interior 2. Therefore, the hook 21 of the engagement part 20 can be hooked to the loop 34 in the vehicle interior 2, thereby temporarily holding the fastening belt 10 in the temporary holding part 30.

3, when the loop 34 of the second belt 32 receives a tensile load F exceeding a specified value in a state where the hook 21 of the engagement portion 20 is hooked, the other end 32b is peeled off from the one end 32a at the detachment portion 33, and the connection is released, resulting in a detached state. At this time, the other end 32b of the second belt 32 is released from the loop 34, so that the loop shape of the loop 34 collapses from its initial state and the holding force of the hook 21 by the loop 34 is weakened. In this way, the temporary holding portion 30 is configured to weaken the holding force of the hook 21 by the loop 34 when the tensile load F increases in a state where the hook 21 of the engagement portion 20 is hooked on the loop 34. At this time, even if the connection at the detachment portion 33 is released, the connection state at the detachment portion 36 is maintained as described above, so that the tension state of the first belt 31 and the second belt 32 is maintained.

In this embodiment, a structure in which the loop 34 is formed on the front side of the vehicle in the temporary holding portion 30 (see Figures 2 and 3) is illustrated, but instead of this structure, a structure in which the loop 34 is formed on the rear side of the vehicle can be adopted by reversing the front and rear of the temporary holding portion 30.

2 and 3, the first belt 31 is provided with an attachment portion 35 to which the vehicle-mounted item A can be detachably attached. The attachment portion 35 is configured with a hook-and-loop fastener similar to the detachment portions 33 and 36 described above. This allows a simple operation to switch between a state in which the vehicle-mounted item A is attached to the first belt 31 and a state in which the vehicle-mounted item A is detached from the first belt 31.

The type of on-vehicle item A is not particularly limited. One example of on-vehicle item A is a triangular warning sign used in an emergency stop of vehicle 1. In addition, various other items mounted on vehicle 1 may be subject to on-vehicle item A.

Next, we will explain the standby state and the loaded object fixing state of the loaded object fixing structure 101 configured as described above.

(standby state)
4, in the standby state of the load fixing structure 101, the user, while getting into the vehicle interior 2, pulls out each of the first fastening belt 10A and the second fastening belt 10B from the floor portion 3 by the corresponding belt drive device 4. Then, the user grasps the hook 21 of the engagement portion 20 fixed to each fastening belt 10 with his/her fingers and hooks it onto the loop 34 of the temporary holding portion 30. This allows the fastening belt 10 to be temporarily held in a state where it is lifted above the floor surface of the vehicle interior 2.

(Items being delivered are fixed)
5, the carry-in object fixing structure 101 is used when carrying an object W into the vehicle interior 2 and fixing it therein. First, a user grasps the hooks 21 of the engagement parts 20 with his/her fingers from outside the vehicle and removes them from the loops 34 of the temporary holding parts 30. This releases the temporary holding of the first fastening belt 10A and the second fastening belt 10B.

Then, while still holding the hook 21 with the user's fingers from outside the vehicle, the user hooks the hook 21 to the engaging portion Wa of the item W in place of the loop 34. The hook 21 on the first fastening belt 10A side is hooked to the right engaging portion Wa, and the hook 21 on the second fastening belt 10B side is hooked to the left engaging portion Wa. The pull-out length of each of the first fastening belt 10A and the second fastening belt 10B is then adjusted by the corresponding belt drive device 4. This allows the item W to be secured to the vehicle interior 2 using the tension of each of the first fastening belt 10A and the second fastening belt 10B.

Here, we will explain the work that the attendant performs using the item fixing structure 101 when the item W is a wheelchair with a user inside. This work is broadly divided into a first work when the attendant gets into the vehicle compartment, and a second work when the attendant gets out of the vehicle compartment. Note that a welfare vehicle equipped with a ramp or lift device for getting on and off the wheelchair is preferably used as the vehicle 1 in this case.

(First Operation)
In the first operation, first, with the load fixing structure 101 in a standby state (see FIG. 4), the caregiver grasps the hook 21 of the engaging portion 20 with his/her fingers from outside the vehicle and removes it from the loop 34 of the temporary holding portion 30. Then, the caregiver drives the belt driving device 4 so that the pulled-out length of the fastening belt 10 becomes longer, and hooks the hook 21 of the engaging portion 20 onto the engaged portion of the wheelchair.

Next, the caregiver enters the vehicle interior 2 together with the wheelchair while driving the belt drive device 4 so that the pulled-out length of the fastening belt 10 is shortened (first entry). At this time, a ramp or lift device is used to move the wheelchair from outside the vehicle to the vehicle interior 2. The caregiver then locks the wheelchair from moving in the vehicle interior 2. Finally, the caregiver fine-tunes the pulled-out length of the fastening belt 10 using the belt drive device 4 so that the tension of the fastening belt 10 is increased. This makes it possible to tether the wheelchair and secure it to the vehicle interior 2 using the tension of the fastening belt 10.

(Second Operation)
The second operation is basically performed in the reverse order to the first operation. First, the caregiver enters the vehicle compartment 2 with the object secured by the object securing structure 101 (see FIG. 5 ) (second entry). Then, after unlocking the wheelchair from traveling, the caregiver gets off the vehicle compartment 2 together with the wheelchair while driving the belt drive device 4 so that the pulled-out length of the fastening belt 10 becomes longer.

Next, the caregiver removes the hook 21 of the engagement part 20 from the engaged part Wa of the wheelchair. After that, while driving the belt drive device 4 so as to shorten the pulled-out length of the fastening belt 10, the caregiver hooks the hook 21 of the engagement part 20 onto the loop 34 of the temporary holding part 30 instead of the engaged part Wa of the wheelchair. This makes it possible to temporarily hold the fastening belt 10 in a state where it is lifted above the floor surface of the vehicle compartment 2.

As described above, by using the item fixing structure 101, it is possible to limit the number of times the caregiver needs to enter the vehicle compartment 2 for the first and second tasks to a total of two times.

According to the above-mentioned embodiment 1, the following effects can be obtained:

In the first embodiment, the fastening belt 10 extending from the floor 3 of the vehicle interior 2 is provided with an engagement portion 20 that can engage with the incoming item W. This engagement portion 20 can be held by a temporary holding portion 30 provided on the interior material 5 facing the vehicle interior 2. That is, the engagement portion 20 can be set to an engagement state with the incoming item W, while the engagement portion 20 can also be set to a temporary holding state by the temporary holding portion 30. When the engagement portion 20 is in a temporary holding state, the fastening belt 10 provided with this engagement portion 20 forms a state in which it is temporarily held on the interior material 5 side. On the other hand, when the engagement portion 20 is in an engaged state, the fastening belt 10 is connected to the incoming item W via the engagement portion 20, so that the incoming item W forms a state in which it is fixed to the vehicle interior 2.

Here, since the temporary holding portion 30 is provided at a higher position than the floor portion 3, when the engagement portion 20 is in a temporary holding state, the fastening belt 10 can be temporarily held in a state where it is raised above the floor surface of the vehicle interior 2. Therefore, the user does not need to pull the engagement portion 20 upward from the floor surface when engaging the item W to be brought in, and can grasp and operate the engagement portion 20 in a position where it is easy to see. As a result, the workload when fixing the item W can be kept low. In addition, the structure in which the temporary holding portion 30 is provided at a higher position than the floor portion 3 is effective in preventing the user from accidentally stepping on the fastening belt 10, and is effective in facilitating the work of fixing the item W.

Therefore, according to the above-mentioned embodiment 1, it is possible to provide an item fixing structure 101 that is easy to work with when fixing the item W to the vehicle compartment 2.

According to the transport object fixing structure 101 of the first embodiment, since the temporary holding part 30 is in the operable position P, the user can grasp the engagement part 20 and temporarily hold it in the temporary holding part 30 or remove it from the temporary holding part 30 by performing operations within reach from outside the vehicle. This eliminates or reduces the effort required for the user to enter the vehicle compartment 2 when fixing the transport object W.

According to the load fixing structure 101 of the first embodiment, the engagement part 20 can be temporarily held by the simple operation of hooking the hook 21 of the engagement part 20 onto the loop 34 of the temporary holding part 30.

According to the load fixing structure 101 of the first embodiment, when the hook 21 of the engagement portion 20 is hooked on the loop 34 of the temporary holding portion 30 and a tensile load F greater than expected acts on the loop 34, the connection state at the detachment portion 33 is released, and the holding force of the hook 21 by the loop 34 is weakened. Therefore, for example, even when the tensile load F acting on the loop 34 via the hook 21 increases due to interference with the fastening belt 10 while the user is in the vehicle compartment 2, the loop 34 weakens the holding force of the hook 21, thereby preventing the user from losing their posture or falling over.

According to the load fixing structure 101 of the first embodiment, the temporary holding portion 30 used for temporarily holding the engagement portion 20 can also be used for detachably attaching the mounted component A. In addition, the mounted component A can be attached and detached with a simple operation.

The present invention is not limited to the above-described embodiment, and various applications and modifications are possible without departing from the purpose of the present invention. For example, the following forms can be implemented by applying the above-described embodiment.

In the above embodiment, the hook 21 of the engagement portion 20 is hooked onto the loop 34 of the temporary holding portion 30 to temporarily hold the fastening belt 10, but instead, a portion corresponding to the loop 34 may be provided on the engagement portion 20, and a portion corresponding to the loop 34 may be provided on the temporary holding portion 30. Furthermore, the shapes of the hook 21 and the loop 34 are not particularly limited, and can be appropriately changed as necessary.

In the above embodiment, a hook-and-loop fastener that releases the connection when a tensile load exceeding a specified value is applied to the detachable portion 33 is used as an example, but a structure other than this hook-and-loop fastener can also be used as long as it can achieve a similar detachable function. For example, a detachable structure that utilizes the adhesive force of a magnet can be used.

In the above embodiment, an example was given of a case in which the temporary holding portion 30 is provided with the mounting portion 35, but this mounting portion 35 can be omitted if necessary.

In the above embodiment, a wheelchair was used as an example of the item W to be carried, but the item fixing structure 101 can be applied to a fixing structure for various items that can be carried into the vehicle compartment 2.
