Description

[Detailed Description of the Invention] The present invention relates to an awning device for a vehicle such as a truck for X-ray photography, blood donation, or other medical treatment or for transporting luggage. The drive arm 3 is tilted up and down in a range from a substantially hanging position to an obliquely upward position; This relates to a vehicle awning device comprising a link 6, one end of which is rotatably pivoted, and the other end of which is attached to the free end of an awning 5.

As shown in Figure 1, as a means of extending a sunshade and rain-shielding awning from the rear entrance of the vehicle to the outside of an X-ray imaging vehicle, blood donation vehicle, etc., the lower end can be freely rotated at the rear entrance. A conceivable method is to rotate the link 6' supported by the link 6' downward and pull out the awning 5' attached to the upper end of the link 6'. Since the awning 5' is extended, there is a drawback that the height H' of the awning 5' becomes lower as the link 6' is pushed down and the awning 5' is extended further.

The present invention was developed in view of the drawbacks of the conventional technology, and its purpose is to prevent the height of the awning from increasing even if the links are rotated and the awning is extended. To provide an awning device for a vehicle capable of extending a high awning without lowering the awning.

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

The vehicle 7 is a large vehicle with a canopy 8 and is equipped with an X-ray camera, a blood sampling device, and the like. Vehicle 7
It may also be a device equipped with other medical equipment, a bookshelf containing books, or a truck for transporting luggage. An opening/closing door 9 is hinged to an opening 1 at the rear of a vehicle 7 with a hinge 10 so as to be freely openable and closable. In FIG. 2, S represents a step, which may be of a rotating type, or may be a permanently installed or driven rotating type. Bevel gear cases 11 are located on both sides of the opening/closing door 9.
A drive arm 3 is attached to a drive shaft 12 that projects horizontally from a bevel gear case 11.
By fixing the base end of the drive shaft 12 in the forward and reverse directions, the drive arm 3 can be freely tilted up and down in a range from a substantially hanging position to an obliquely upward position.
The drive mechanism 2 of the drive arm 3 is driven by a DC deceleration motor 13 mounted on a canopy 8 mounted on the vehicle 7, and has a built-in worm wheel 15a that is decelerated and driven by an output shaft 14 of the deceleration motor 13. Approximately 1/30
a first deceleration section 15 that decelerates to
The input shaft 22 from 5 is also connected to the worm reduction mechanism 1.
6a to reduce the speed to about 1/30, and 16
, the second reduction unit 16 and the bevel gear case 11
It is comprised of a first intermediate shaft 17 that interlocks and connects a bevel gear mechanism (not shown) therein. The drive system of the drive arm 3 on the left in FIG. The driving force is transmitted to the portion 16b.

Note that the design of the drive mechanism 2 can be modified in various ways.

The second intermediate shaft 18 serves as a winding shaft 19 for the awning 5. The awning 5 is wound around the winding shaft 19, and the winding shaft 19 is rotated in forward and reverse directions by the deceleration motor 13, so that the awning 5 can be fed out and rolled up. A deceleration motor 13 as a drive means 4 for the awning 5, and a first and second deceleration section 1
5, 16 and the second intermediate shaft 18 partially serve as the drive mechanism 2 of the drive arm 3, but they may be of different systems.

The free end of the drive arm 3 is bent into a substantially L shape, and a link 6 is rotatably attached to this bent portion 20 with a pin 21. A horizontal bar 23 is installed at the free ends of the left and right links 6, 6, and this horizontal bar 2
3 is attached to the free end of the tent 5. According to such a configuration, the drive arm 3 is driven and rotated upward in the order of a, b, and c in FIG.
The link 6 is pushed upward, and the winding shaft 19 is driven and rotated to let out the awning 5, so that the awning 5 is extended to a height H. Then, by the reverse rotation of the deceleration motor 13, the drive arm 3 and the winding shaft 19 are reversely rotated via the drive mechanism 2 and the drive means 4, and the awning 5 is rolled up and stored. Note that the driving relationship between the winding shaft 19 and the drive arm 3 is as follows:
When the awning 5 is extended approximately 10 times in the forward direction, the drive arm 3 can be rotated from the lower limit of the hanging position to the upper limit of approximately 120° rotation. Can be changed. The deceleration motor 13 can be operated from the driver's seat of the vehicle.

In summary, the present invention has a drive arm that is placed on both sides of an opening such as the rear entrance of a vehicle and that is tilted up and down by a drive mechanism in a range from a substantially hanging position to an obliquely upward position, and a drive arm that is driven at the upper edge of the opening. Since it is composed of an awning that is fed out, rolled up and stored by a means, and a link that has one end rotatably pivoted to the free end of the drive arm and the other end engaged to the free end of the awning, The link can be pushed up by the upward driving rotation of the drive arm, which prevents the awning from lowering compared to the conventional means of supporting the awning by simply rotating the link. , the more the awning is extended, the more the link is pushed up, so there is an advantage that the awning can be extended higher.
