Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention mainly relates to a foldable shade fixture for vehicle-based construction machinery.

[Conventional technology]

As shown in FIG. 1, this type of folding type sun cover fixture has stoppers 6 each fixed to a pair of mounting brackets 5 attached to both sides of the upper surface of the vehicle body 3 in front of the driver's cab 4.
and a quadrilateral link mechanism 2 which is rotatably attached to each mounting bracket 5 and supports the awning 1, and which is fitted into an awning stay 8 facing the stopper 6 of each quadrilateral link mechanism and fitted into the stopper 6. It consists of a tightening ring 7 to be removed and a guide 10 supporting and guiding the tightening ring in the middle of the awning stay 8.

In such a folding type sunshade fixture, the sunshade 1 is placed in the assembly position shown in FIG.
When the tightening ring 7 is removed from the stopper 6 and pushed forward, it is folded as shown by the imaginary line.

[Problem that the invention attempts to solve]

However, with conventional products such as those mentioned above,
When the awning stay 8 is rotated from the folded state to the direction in which it is propped up, the stopper 6 side of the tightening ring 7 may drop as shown in FIG. As such, the tightening ring 7 is caught between the awning stay 8 and the stopper 6, and the member may be damaged by the impact at that time. Also, since the awning cannot be fixed in a state where the tightening ring 7 is pinched, once the awning stay 8 is separated from the stopper 6, the tightening ring 7 is lifted upward, and then the awning stay 8 is moved to the stopper 6 again. By abutting and fitting the tightening ring 7 into the stopper 6, the shade 1 was fixed. In this case, since the pair of quadrilateral link mechanisms 2 are arranged apart from each other on both sides of the vehicle body, it is impossible for one person to operate the quadrilateral link mechanisms 2 and the tightening ring 7. That is, a plurality of workers are required and the work becomes complicated.

Therefore, in the present invention, the tightening ring is prevented from being caught between the awning stay and the stopper, and the work of assembling and folding the awning can be performed by one person.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a stopper provided on the vehicle body side, a quadrilateral link mechanism rotatably attached to the vehicle body side to support the awning, and a quadrilateral link mechanism of the quadrilateral link mechanism. In a folding type awning fixture comprising a tightening ring that is fitted into an awning stay facing the stopper and which is fitted into and removed from the stopper, a locking piece that can be hung and removed from the tightening ring is hung thereon. The tightening ring is attached to the awning stay so that it does not come into contact with the stopper.

[Effect]

The above technical means works as follows.

Since the tightening ring fitted into the awning stay is suspended by the locking piece, it does not fall into the base of the awning stay due to the rotation of the awning stay when the awning is assembled and folded. In addition, the tightening ring that is hung on the locking piece does not come into contact with the stopper, so when the awning stay is brought into contact with the stopper when assembling the awning, the tightening ring can be removed from the locking piece in that state. Assembling the awning is easy because it can be removed and fitted into the stopper, and the awning can be folded by removing the tightening ring from the stopper, hooking it to the locking piece, and then tilting the awning stay forward. , one person can easily assemble and fold the solar cover.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. 1st
In the figure, 1 is a sunshade, 2 is a pair of left and right quadrilateral link mechanisms that are rotatably attached to mounting brackets 5 provided on both sides of the front upper surface of the vehicle body 3 in front of the driver's cab 4 and support the sunshade 1. Reference numeral 6 indicates a stopper of the mounting bracket 5 protruding upward near the driver's cab 4, 7 indicates a tightening ring fitted into the awning stay 8 facing the stopper 6 of the quadrilateral link mechanism 2, and 9 indicates the awning stay 8. This is a locking piece that is fixed to the awning stay 8 so that when it is in contact with the stopper 6, the awning stay 8 is positioned directly above the top of the stopper 6, and the tip of the awning stay 8 is facing upward. The length has been selected to allow for hanging. Reference numeral 10 denotes a guide that supports and guides the tightening ring 7 in the middle of the awning stay 8.

In FIG. 2, reference numeral 12 denotes a receiver which is fixed to the stopper 6 and receives the awning stay 8.

FIG. 2 shows a partially cutaway side view of the sunshade fixing device when the quadrilateral link mechanism 2 is tilted toward the front of the vehicle body and the sunshade 1 is folded. In this folded state,
The tightening ring 7 engages with the locking piece 9 and the guide 10, and its lower end abuts against the recess 11 of the mounting bracket 5. When the quadrilateral link mechanism 2 is rotated clockwise in the figure from this folded state, the tightening ring 7 is engaged with the locking piece 9 and the guide 10 and hangs down (Fig. 3), and the awning stay 8 is moved to the stopper position. 6, the upper end of the tightening ring 7, which is hung on the locking piece 9, is located above the stopper 6, as shown in FIG. There is no. Therefore, when the awning stay 8 comes into contact with the stopper 6, the tightening ring 7 can be fitted into the stopper 6 in that state (FIG. 5), and the awning assembly work can be carried out by one person.

Next, in the awning assembly state shown in FIG. 5, the tightening ring 7 is removed from the stopper 6 and hooked onto the locking piece 9, and the quadrilateral link mechanism 2 is tilted toward the front side of the vehicle body, as shown in FIG. 2 again. A sun-covered folded state is obtained.

In this embodiment, a guide 10 is provided to support and guide the tightening ring 7 in the middle of the awning stay 8, but this guide 10 may be omitted. That is, when the tightening ring 7 is hooked to the locking piece 9, even if the quadrilateral link mechanism 2 rotates, the locking piece 9
Also, the awning stay 8
If the folding is completed before the shank faces downward, the tightening ring 7 will not move toward the sun cover 1 side. Further, as a means for restricting the movement of the tightening ring 7, a pin facing the locking piece 9 may be provided protruding from the awning stay 8 instead of the guide 10. Further, in this embodiment, the stopper 6 is provided with a receiver 12 for receiving the awning stay 8, but the function of this receiver is provided on the locking piece 13 as shown in FIGS. 6 and 7. 6 may be accepted.

〔effect〕

As is clear from the above explanation, according to the present invention, the tightening ring fitted into the awning stay is further hung on the locking piece and does not come into contact with the stopper, so that the tightening ring is attached to the awning stay. It is not caught between the stoppa and the stoppa. Therefore, it is possible to prevent the awning stay and stopper from being damaged by the tightening ring, and when the awning stay contacts the stopper, the awning stay and stopper can be connected with the tightening ring in that state, making it easy to assemble the awning. Furthermore, to fold the awning, all you have to do is hook the tightening ring removed from the stopper to the locking piece and then fold the awning stay toward the front of the vehicle, so the assembly and folding of the awning can be done in one step.
It can be easily performed by humans. Furthermore, the folding type sunshade fixing device of the present invention has a simple structure of adding a locking piece to the conventional product, so it can be provided at low cost, and it can be easily applied to the conventional product, eliminating its drawbacks. .
