Description

  The present invention relates to a curtain structure for a cargo automobile, and more particularly to a cab curtain having a nap bed.

  FIG. 6 shows a cab 2 with a bed of a lorry in which the curtain of the present invention is used. A bed for a break or a nap is provided behind the driver's seat 4 for the driver to drive.

  There are three cases for taking a break or a nap using this bed 6, one of which is a bed and the other at the driver's seat at the same time. A case in which one driver is driving and driving while the other driver is resting or taking a nap when the two drivers are driving alternately (second case), There are cases where a single driver stops and takes a rest or a nap (third case).

  The use of curtains differs depending on the case, but the windows to be shielded are the windshield 8 in front of the driver's seat 4, the side windows 10 provided on the left and right entrance doors 9, and the cab at the rear of the entrance door 9. 2 side rear windows 14 provided on the left and right sides of the cab 2, and a rear window 16 provided on the rear end of the cab 2.

  FIG. 7 is a top view excluding the roof of the cab 2 to show the arrangement of the curtain. The first curtain 21A that partitions the driver's seat 4 and the bed 6, the left and right rear windows 14 at the rear of the cab, and, if necessary, The cab 2 is provided with second curtains 22AL and AR installed on the left and right sides for shielding external light from the windshield 8 and a third curtain 23A for shielding external light from the rear R. Yes. Reference symbol F indicates the forward direction of the cab 2, and reference symbol R indicates the backward direction of the cab 2.

  In the first case, that is, when two people take a nap at the same time, it is preferable that the entire interior of the cab 2 shields outside light by all the curtains 21A, 22AL, 22AR, 23A, but the front end portion of the second curtain 22A The conventional coupling such as drawing of 22a or superposition of magic fasteners has a defect that a gap is generated and complete light shielding cannot be performed. The same is true for complete shading in the third case, i.e. single-person operation.

  In the second case, that is, when one person takes a nap during traveling, referring also to FIG. 8, the rear window 16 is shielded by the third curtain 23 </ b> A, and the light in the driver's seat 4 ( The second curtain 22AL and AR are pulled out to the front end of the bed 6 to block the outside light from the driver's seat 4 and the left and right side rear windows 14. . However, when the second curtain 22AL and the AR end are fixed to the curtain rail or the cab 2, the clearance between the end 21a of the first curtain 21A is unavoidable due to the swinging of the curtain during traveling. The shading was not possible.

Further, in FIG. 8, when the end 22a of the second curtain 22AL is fixed to the curtain rail or the cab 2, the end 22a is detached from the curtain rail or the fixed portion of the cab 2 during sudden braking or turning. There is a concern that the side window 10 and the windshield 8 may be blocked by sliding along the curtain rail.
In addition, although not shown, the first curtain 21A is accommodated and fixed to the cab 2, and there is a drawback that it becomes unobtrusive because it sways and sways.

  Further, in the third case where the driver driving alone takes a nap, the complete light shielding to the bed 6 is the same as the first case in FIG.

No effective solution has been proposed for each of the above disadvantages associated with curtains.
As another conventional technique, for example, there is a technique that defines a positional relationship between a duct and a curtain of an air conditioning unit (see, for example, Patent Document 1).
However, the related art relates to air conditioning in a truck bed and does not solve the above-described problems.
JP-A-8-150826

  The present invention has been proposed in view of the above-described problems of the prior art, and can guarantee the light-shielding property of the bed space when the curtain is used, and the curtain stored when the curtain is stored obstructs the driver. The object of the present invention is to provide a curtain structure for a freight automobile that can prevent such a problem and reliably prevent the stored curtain from being unfolded during traveling.

Each end of (21) and the second curtain (22) is configured to be connectable.

  According to the present invention having the above-described configuration, the first coupling means is provided at both ends of the first curtain, and the second coupling means is provided at the cab front end of the second curtain. The first coupling member and the second coupling member are configured to be coupled to each other, so that the curtains are coupled to each other, and the first curtain is fixed to the cab via the second curtain. Therefore, there is an advantage that the second curtain is not self-propelled due to the loss of direct fixing to the cab as in the prior art.

  The second curtain can cover a window on the rear side of the cab and a position near the center of the windshield in front of the cab, and the second coupling member can connect the cab front side end of the second curtain to the cab side part. Since it is configured so that it can be coupled to the first coupling member when moved to a position near the rear window (Claim 2), the ends of the first and second curtains are coupled to each other. There is an advantage that the end of the curtain of 1 is prevented from shaking and obstructive and harsh.

Since the first coupling member and the second coupling member are constituted by snap members (claim 2), there is an advantage that the coupling can be performed with high reliability without being easily put on and taken off.
If the snap member is a so-called hook of hook, there are advantages that it is easy to define wearing and releasing force, high reliability, and easy use.
