Description

  TECHNICAL FIELD The present invention relates to a vehicle outside mirror for a cab truck having a cargo compartment protruding rearward from the roof of a cabin, and in particular, a vehicle outside mirror capable of visually recognizing an upper portion of a cargo compartment from a driver's seat. It is about.

An outside mirror is attached to the vehicle for safety confirmation at the rear and side, and the driver drives the vehicle while confirming safety at the rear and side by the outside mirror.
There are various types of vehicles. For example, a cab truck with a rear cargo compartment that protrudes above the roof of the cabin (guest room), such as a van-mounted vehicle, usually has an opening on the rear side of the vehicle. And a mirror housing whose other part is closed, a mirror disposed in an opening of the mirror housing on the vehicle rear side, and a stay fixed to the mirror housing on one side and attached to the vehicle body on the other side. The provided vehicle outside mirrors are attached to the left and right sides of the vehicle body.

  Of the cab trucks having a luggage compartment projecting upward from the height of the cabin at the rear, a small one is often used by, for example, a courier. Since courier companies need to move to the vicinity of the parcel delivery destination by car, private houses are often crowded and travel through narrow alleys, and the eaves and trees of private houses may become obstacles to traffic. is there. However, with the conventional outside mirror, although it is possible to check the rear and side of the vehicle from the driver's seat, it is difficult to check the upper part of the luggage compartment, especially the upper front edge part. In order to prevent contact with obstacles such as eaves and trees, it is necessary for the driver to get out of the vehicle and check the upper front end of the cargo compartment, which is very troublesome.

  Therefore, in addition to the conventional outside mirror for confirming the rear and side of the vehicle, it is considered that a hole is formed in the stay, and a mirror that can visually confirm the upper front end of the cargo compartment from the driver's seat is fixed with a bolt. However, when the mirror is additionally installed in this way, the stay may break due to vibration caused by the running of the vehicle, and thus it is difficult to put it into practical use for a long time.

  Patent Document 1 discloses a two-mirror vehicle outside mirror 01 shown in FIG. This is a long rectangular lower convex mirror 07 for visually recognizing the rear of the vehicle, an upper convex mirror 08 for confirming the upper front end of the cargo compartment, a support base 015 for fixing the lower convex mirror 07 and the upper convex mirror 08, This is a two-mirror type vehicle outside mirror comprising a partition plate 015a integrated with a support base 015 for partitioning the lower convex mirror 07 and the upper convex mirror 08, and a mirror housing 09 housing the support base 015. When such a two-mirror vehicle outside mirror 01 is used, it is possible to visually recognize the front upper end of the vehicle with the upper convex mirror 08 and visually recognize the rear and side of the vehicle with the lower convex mirror 07 from the driver's seat.

  Further, Patent Document 2 discloses a vehicle outside mirror for visually recognizing two different directions, but a mirror for visually recognizing the side lower end of the vehicle, and an outside mirror mounted on the vehicle. An outside mirror is disclosed in which a light for irradiating a direction is disposed, and the mirror and the light can be housed in the housing by a drive mechanism disposed in the housing.

Registered Utility Model Publication No. 3061821 Japanese Utility Model Publication No. 5-82678

However, in the technique disclosed in Patent Document 1, the upper convex mirror 08 and the lower convex mirror 07 are arranged vertically, so that the entire vehicle outside mirror 01 becomes vertically long and heavy. For this reason, vibration is likely to occur during traveling, and it is difficult to visually recognize the mirror, and the stay 02 for attaching the mirror to the vehicle body may be broken. Furthermore, since the surface area of the vehicle outside mirror 01 is increased, the air resistance during traveling of the vehicle is increased. Further, if the outside mirror 01 is made small in order to prevent the vibration and air resistance from increasing, each of the upper convex mirror 08 and the lower convex mirror 07 becomes small, and a sufficient field of view cannot be secured. I can't.
Moreover, since the technique disclosed in Patent Document 2 requires the provision of a light and a drive mechanism, the structure inside the housing becomes complicated and the weight of the entire outside mirror becomes heavy. For this reason, when the mirror is attached to the vehicle body via the stay, the mirror vibrates during traveling, making it difficult to visually recognize the mirror, and the stay to which the mirror is attached may be broken.

  Accordingly, in view of the problems of the prior art, the present invention has a simple configuration and the rear mirror is provided with a luggage compartment projecting above the height of the passenger cabin at the rear without excessively increasing the weight of the outside mirror. Another object of the present invention is to provide a vehicle outside mirror capable of visually recognizing the upper part of the cargo compartment in addition to the side surface.

In order to solve the above problems, in the present invention,
An outside mirror for a vehicle of a cab truck having a luggage compartment projecting upward from a roof of a cabin, a rail receiver disposed in a mirror housing constituting the outside mirror for the vehicle, and along the rail receiver A slide rail capable of traveling in the vertical direction and an auxiliary mirror attached to the slide rail and housed in the rear part of the mirror main body of the outside mirror, the slide rail extending in the vertical direction along the rail support By running, the auxiliary mirror can be switched between the storage position and a visual recognition position where the auxiliary mirror protrudes above the mirror body of the outside mirror so that the upper part of the cargo compartment can be seen from the driver's seat. It is characterized by comprising.

Thereby, the upper part of the luggage compartment, in particular, the upper front end can be visually recognized by the auxiliary mirror from the driver's seat while ensuring the conventional function of visually recognizing the rear and side of the vehicle.
Furthermore, since a driving mechanism and a light are not required, the weight does not become extremely larger than that of a conventional outside mirror, so that breakage of the stay due to vibration during traveling can be prevented.
Moreover, since the conventional mirror for visually recognizing the back and sides has a conventional configuration, there is no problem in the visibility of the back and sides.

In addition, the auxiliary mirror may be switched between a visual recognition position and a storage position, and the auxiliary mirror may be used as a storage position when traveling on a wide road such as an expressway, and the auxiliary mirror may be used as a visual recognition position when traveling on a narrow alley.
Since wide roads such as expressways normally run at high speeds, it is effective to reduce the air resistance received by the entire outside mirror using the auxiliary mirror as the storage position. Since there are almost no obstacles that can come into contact, even if the auxiliary mirror is in the storage position, there is no problem in safety confirmation.
Also, since narrow roads usually run at low speeds, the air resistance received by the entire outside mirror does not become extremely large even when the auxiliary mirror is in the viewing position, and such roads may have obstacles around them. Therefore, by setting the auxiliary mirror to the visual recognition position, it is possible to travel while preventing the upper part of the luggage compartment from coming into contact with obstacles such as eaves and trees of private houses.

Further, a lock mechanism is provided for fixing the slide rail so as not to move at each of the storage position and the visual recognition position.
Thereby, since the position of the auxiliary mirror can be surely fixed at each of the storage position and the visual recognition position, it is possible to prevent the position of the auxiliary mirror from changing during traveling.

The mirror housing can be divided into an upper housing located at the upper part and a lower housing located at the lower part. The upper housing is attached to the slide rail, and is moved up and down as the slide rail travels in the vertical direction. It is characterized by moving in the direction.
Accordingly, it is possible to prevent rainwater and the like from entering the mirror housing regardless of whether the auxiliary mirror position is the storage position or the visual recognition position.

In addition, a compression spring that biases the slide rail upward is attached to the lower part of the slide rail, and the auxiliary mirror attached to the slide rail becomes the storage position by pressing the slide rail. The upper visual recognition position is obtained by the biasing force of the compression spring.
Accordingly, when the slide rail is not fixed by the lock mechanism, the auxiliary mirror is positioned at the visual recognition position. Therefore, for example, even if the lock mechanism breaks down, the auxiliary mirror is always located at the visual recognition position, and it is possible to prevent a state where the front front end of the cargo compartment cannot be confirmed.

Further, the vehicle outside mirror is mounted on the left side of the vehicle, and when the auxiliary mirror is positioned at the visual recognition position, the upper left part of the luggage compartment can be visually recognized from the driver's seat.
Usually in Japan, the driver's seat is located on the right side of the vehicle. The front right end of the cargo compartment can be seen directly from the driver's seat, so if only the upper left front edge of the cargo compartment can be seen by the auxiliary mirror, the top front edge of the cargo compartment is an obstacle such as the eaves of a private house or trees even in a narrow alley. It is possible to travel while preventing contact with the vehicle.
This eliminates the need to install rail supports, slide rails, and auxiliary mirrors on the right side, so that the total part cost for the left and right outside mirrors can be saved.

  As described above, according to the present invention, the structure is simple and the weight of the outside mirror does not become extremely large, and the rear side and the side of the cab truck provided with the luggage compartment protruding above the height of the cabin are provided on the rear side. In addition, it is possible to provide a vehicle outside mirror that can visually recognize the upper part of the cargo compartment.
