Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary seat provided on the side of the driver's cab of a motor vehicle, particularly a parcel delivery motor vehicle.

Recently, the service industry called courier service, which delivers parcels etc. to companies, homes, etc., has been expanding. The delivery vehicle used for this delivery is required to have several special functions due to its purpose. For this reason, delivery vehicles such as those shown in FIGS. 1 and 2, for example, have been designed. That is, the interior of the delivery vehicle 1 is divided into a driver's cabin 5 by a partition wall 3 on the rear side of the driver's seat 2 and a partition door 4 that is slidable in the width direction of the vehicle.
and a luggage compartment 6. Further, the right door 7 on the side of the driver's seat 2 slides along the outer surface of the vehicle body 8, while the left door 9 on the opposite side slides into a recess 10 formed on the outer surface of the vehicle body 8. It's becoming like that. Furthermore, a double door opening/closing door 11 is provided at the rear of the luggage compartment 6.

In such a delivery vehicle 1, loading parcels for delivery into the cargo compartment 6 is done by opening the opening/closing door 11 at the rear of the vehicle body, but when delivering to each home, the driver The partition door 4 is opened and closed to take in and take out cargo, and the left door 9 is opened and closed to load and unload. (The reason why the right side door 7 is not used is because in Japan, people drive on the left side, so it is dangerous to go in and out on the right side, and also because the houses of delivery destinations are often on the left side.) For this reason, the driver is seated in the seat. Rather than getting on and off on the right side of seat 2,
Since many passengers board and exit vehicles on the left side, it is especially desirable that the left side of the driver's seat be easily accessible.

By the way, in these delivery vehicles, the parcels usually handled are often relatively small, and the driver can make deliveries by himself, and the driver's seat is often sufficient for one person, but depending on the parcel, In some cases, an assistant is required, and there is a desire to provide an auxiliary seat. In this case, the auxiliary seat is usually installed to the left of the driver's seat, and when there is no assistant, that is, when the auxiliary seat is not in use, emphasis is placed on the ease of getting out of the seat on the left side of the driver's seat. ,
There is a desire to store the auxiliary seat in a position where it will not interfere with getting out of the seat as much as possible.

Regarding storing the auxiliary seat,
For example, as disclosed in Utility Model Publication No. 49-40100, there is an auxiliary seat for bus passenger seats in which the auxiliary seat is erected on the side of the main seat after the back seat is folded. However, when such an auxiliary seat is used for a delivery vehicle, when the auxiliary seat is stood up next to the driver's seat, the upper end of the auxiliary seat is higher than the driver's seat surface, and the auxiliary seat is Since it is located on the side of the seat, there is a problem that it gets in the way when you leave the seat.

In view of the above problems, the present invention is provided on the side of the driver's seat in a delivery vehicle, etc., and when not in use, it can be placed upright on the driver's seat side and then moved to the rear and stored at a position behind the driver's seat. The purpose is to provide an auxiliary seat with a

The auxiliary seat of the present invention has a support column fixed to the floor next to the driver's seat, and the base is rotatable in the left and right directions of the driver's cabin and slidable in the front and rear directions by means of a rotating shaft provided at the top of the support column. A base is supported, a seat bottom is provided on this base, and the end of the seat back is rotatably supported so that it can be folded over the seat bottom, and when an auxiliary seat is used, the seat bottom is When not in use, the locking means is released, the seat bag is folded over the seat bottom, and the seat bag is rotated around the rotation axis to operate the seat. The device is characterized in that it can be moved rearward and stored at a position behind the driver's seat by standing up on the seat side and sliding rearward on the rotating shaft. Note that, due to the structure of the auxiliary seat, the above-mentioned locking means can be divided into means for preventing rotation of the base relative to the support column and means for preventing sliding, and these may be combined into a single means, or each may be combined into a single means. Each means may be separate.

According to the present invention, when the auxiliary seat provided on the side of the driver's seat is not in use, it can be stood up on the driver's seat side, moved rearward, and stored at a position behind the driver's seat. When the driver leaves his/her seat during work (delivery), it is easier for the driver to leave the seat without being obstructed, and the auxiliary seat occupies less floor space than when the auxiliary seat is fixed. This means that the floor space on the side of the driver's seat can be used more widely, making it easier for workers to move around, and that there is more space to take out the next package from the luggage compartment and temporarily store it during delivery. It has advantages and increases work efficiency. That is, according to the present invention, it is possible to provide an auxiliary seat for carrying an assistant along, and to minimize the hindrance to the driver's ability to leave the seat and the pressure on the space to the side of the driver's seat caused by the auxiliary seat. Can be done.

Note that in this specification, all directions such as front and rear, left and right, etc. are expressed with the driver sitting in the driver's seat. In other words, the direction of travel of the car is forward,
Left and right are shown as left and right in the direction of travel.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 is a sectional plan view of an automobile equipped with an auxiliary seat according to the present invention, and is the same as the example of the automobile shown in FIG. 2 except that it is equipped with an auxiliary seat 12, and the same parts are Numbers are given and explanations are omitted. As shown in this figure, the auxiliary sheet 12
is provided on the left side of the driver's seat 2, and when the driver opens and closes the partition door 4 to put in and take out luggage, or opens and closes the left door 9 to get on and off, the There are many opportunities for workers to leave their seats, and if the auxiliary seat is kept out of the way, work efficiency can be significantly improved. In this figure, the solid line indicates the auxiliary seat 12 is stored in the storage position, and the chain line indicates the auxiliary seat 12 in the use position.

4 to 9 show examples of the auxiliary seat according to the present invention, in which FIG. 4 is a front view, FIG. 5 is a right side view, and FIGS. 6, 7, and 8 are The sectional view and FIG. 9 are perspective views. Examples of the auxiliary sheet according to the present invention will be described in detail below using these drawings.

As shown in FIGS. 4 and 5, a column 21 is fixed to the floor 20 next to the driver's seat, and a cylindrical body 21a extending in the front-rear direction is fixed to the upper part of the column 21. As shown in FIGS. A shaft 22 is rotatably inserted into this cylindrical body 21a to constitute a rotating shaft. However, as shown in FIG. 9, the cylindrical body 21a is provided with a groove 21b extending in the circumferential direction and a groove 21c extending in the axial direction, and the ends of these grooves 21b and 21c are connected to each other. It forms a letter-shaped groove.
The bolt 30 passes through these grooves 21b and 21c.
is screwed together with the shaft 22 inserted into the cylindrical body 21a. Therefore, the movement of the shaft 22 relative to the cylindrical body 21a is restricted by the bolt 30 and the grooves 21b, 21c, and when the bolt 30 is in the groove 21b, the movement of the shaft 22 with respect to the cylindrical body 21a is limited by the groove 21b.
Rotation along the groove 21c and sliding movement along the groove 21c when the bolt 30 is in the groove 21c are only possible. It goes without saying that a pin or the like may be used instead of the bolt 30. Furthermore, axis 2
Both ends of 2 are fixed to the base 23,
As shown in FIG. 6 (a sectional view taken along the line - in FIG. 5), the shaft 2 is installed in bushes 23a, 23a fixed to both ends of the base 23, respectively.
2 is inserted, and pins 23b, 23b are press-fitted into holes coaxially penetrating the bush 23 and the shaft 22 in the radial direction, thereby fixing the shaft 22 to the base 23. For this reason, the base 23 is attached to the column 21 along with the shaft 22 in the grooves 21b and 21c provided in the cylindrical body 21a.
0 can be rotated left and right within the range of movement (arrow B in the figure).
(in the direction shown by arrow D), and is slidable back and forth (in the direction shown by arrow D in the figure). Note that the range of rotation and sliding of the base 23, that is, the size of the grooves 21b and 21c, is approximately
90°, and arrow B shown in Figure 4
The base 23 can be rotated from a use position (indicated by a solid line) in which the upper surface of the base 23 is horizontal to a storage position (indicated by a chain line) in which it is rotated 90 degrees counterclockwise in the figure. Regarding the groove 21c extending in the axial direction, the bolt 30 and the groove 21c match only when the seat is rotated by 90 degrees to the storage position, that is, when the seat is raised toward the driver's seat, and the bolt 30 and the groove 21c are able to freely slide back and forth. Movement indicated by arrow D in FIG. 5 becomes possible.

As shown in FIG. 7 (a partial cross-sectional view of only the base part taken along the line - in FIG. 4), the upper surface of the base 23 has two parallel angles 23c extending in the left-right direction. 23c are fixedly installed, two roller shafts 23d are provided at right angles to each angle 23c and at equal intervals, and two rollers 23e are rotatably provided on each of the shafts 23d.
In addition, two U-shaped rails 24b, 24b extending in the left-right direction and parallel to each other are fixedly installed on the lower surface of the seat frame 24, which integrally forms the seat bottom with the cushion 24a placed on the upper surface. The open portions of the rails 24b, 24b are fixed so as to face forward in the rail placed on the front side, and toward the rear in the rail placed on the rear side. On the other hand, the roller 23e
is attached so as to protrude rearward at the angle 23c provided on the front side, and is attached so as to protrude forward at the rear angle 23c. Therefore, by fitting the rollers 23e to the U-shaped rails 24b, the base 23 moves the seat frame 24 in the left-right direction (in the direction of arrow C in FIG. 8, which shows the cross section along the line - in FIG. 7). It is slidably supported. Note that the above configuration is for holding the seat frame 24 slidably in the left and right directions with respect to the base 23, and from this point of view, the number of the rollers is not limited to four, and the mounting of the rails and rollers is not limited. In other words, the rails may be provided on the base 23 and the rollers may be provided on the seat frame 24. Furthermore, the seat frame 2 is connected to the base 23.
4 may be made to slide. For example, the base 23 may be provided with a groove extending left and right, and the protrusion provided on the seat frame 24 may be fitted into the groove and slid along the groove.

In addition, the seat back 25 has one end connected to the seat frame 2.
It is rotatably supported in the front-rear direction (in the direction shown by arrow A in the figure) by a support shaft 26 provided at the rear of 4, and is in the operating position shown by the solid line (from this point onward, it is located at one of the locking means). It is prevented from falling over by a stopper 25a), and can be folded forward to overlap with the cushion 24a (indicated by a two-dot chain line in the figure).

Further, a stay 27 for holding the cushion 24a and the seat bottom formed by the seat frame 24 in a substantially horizontal use position is rotatable by a stay shaft 29 provided at one end at the bottom of the seat frame 24. The other end of the support 21 is supported by a stay receiver 21c fixed to the side of the support 21. (See Fig. 8) In order to prevent the stay 27 received by the stay receiver 21c from coming off, the hook 27a fixed to the end of the stay 27 is pulled downward by a locking tool 28 as a locking means. It is tension-locked. The purpose of this stay 27 is to hold the seat bottom in an almost horizontal use position. For example, instead of the stay, the groove position shown in FIG. It may also be configured so that the bolt 30 comes into contact with it and stops. However, in this case, it is necessary to separately provide a locking means to prevent the seat bottom from rotating around the shaft 22.

However, the seat bottom (seat frame 24
Since the entire structure (consisting of the seat frame 24a and the cushion 24a) can slide on the base 23 while rotating around the shaft 22 and is unstable, it can be used as a removable locking means to prevent the seat frame 24 from moving relative to the base 23. Blocking means (not shown), e.g. base 23
The screw means for tightening the seat frame 24 together with the seat frame 24
It is set in.

Furthermore, a handle 24c is fixed to the side of the seat frame 24 to facilitate storage of the auxiliary seat.

In the auxiliary seat configured as described above, when the auxiliary seat is used, the stay 27 locked by the locking tool 28 prevents the rotation shown by the arrow B about the shaft 22, and also prevents the above-mentioned prevention. Seat frame 2 relative to base 23 by means (not shown)
4 and hold the seat bottom in a substantially horizontal use position, and move the seat back 25 in the direction of arrow A.
It can be raised in the direction shown by and held in a substantially vertical use position determined by the stopper 25a, and can be provided as an auxiliary seat for an assistant or the like. When the auxiliary seat is not used, after folding the seat back 25 over the seat bottom cushion 24a (operation in the direction of arrow A), the locking tool 28 and the movement preventing means between the base 23 and the seat frame 24 are removed. Release it, rotate the base 23, seat bottom, and seat back 25 together around the shaft 22 toward the driver's seat (located on the right side of the auxiliary seat) to stand up (operation in the direction of arrow B), and then Then, the seat frame 24 is slid up and down relative to the base 23 (since the base etc. are raised as one unit, it is horizontal in the use position, but in this case it is vertical), and the base is slid against the support 21. By sliding back and forth, the seat bottom and seat back can be pushed down as one unit (operation in the direction of arrow C) and moved rearward (operation in the direction of arrow D) to be stored.
In this case, the operation of pushing down and the operation of moving backward are the same no matter which one is performed first.

As explained above, according to the present invention, when the auxiliary seat provided on the side of the driver's seat is not in use, it can be stood up on the driver's seat side, moved rearward, and stored at a position behind the driver's seat. The seat retracts to the rear, so the auxiliary seat does not get in the way of the driver, allowing for smooth exit and exit, and the space on the side of the driver's seat is also larger compared to when the auxiliary seat is fixed, making delivery work easier. efficiency can be improved.
