Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention This invention is, for example, a case where a frame constituting a hood of a truck bed is assembled from pipe materials and a hood cloth (sheet) is stretched over the frame. The present invention relates to a sheet end treatment material that is used to easily, surely and visually stop the end of the sheet.

2. Description of the Related Art Conventionally, a so-called wing body in which a hood is placed on a truck bed and a side surface, a back surface, or a roof portion of the hood can be freely opened and closed is widely known and well-known (for example, Japanese Utility Model Publication No. 54- No. 2496, Japanese Utility Model Publication No. 57-21773).

When a hood is constructed by stretching a hood cloth (sheet) on the outer surface of a skeleton assembled from a pipe material or the like, conventional means for fixing the hood to the skeleton is, for example, Japanese Utility Model Publication No. 57-21773. As shown in FIG. 1 and illustrated in FIG. 7 of the drawing, the lower end of the side portion of the seat (hood cloth) a is fastened to the cargo bed c by knitting with a rope b in a zigzag shape. The rope d passed along the inner peripheral edge of the back surface of the seat a is tensioned in an annular shape and fixed by being fixed to the loading platform c.

Alternatively, as illustrated in FIG. 8, the seat (hood cloth) a and the seat e on the back surface are fixed to the gate-shaped support g with an annular hook (band) f.

As another means for stopping the back sheet e, as shown in FIG. 9, a flap h is formed in series on the back portion of the sheet a, and a magic tape j is provided on the flap h and the back sheet e. Stopping, or as shown in Fig. 10, the frame is composed of double pipe materials m and n, and seat e
It is also practiced to fold the outer pipe material n and fasten the end to the inner pipe material m like knitting with a rope k.

The problem to be solved by the present invention is that the work of fastening the sheet a or e to the loading platform c or the pipe material m as in the conventional knitting with the ropes b or e, k is very troublesome and troublesome. Skilledness is also required, and in some cases, it is easy to carry out manual work. Moreover, the finished appearance does not look good, and there is a problem that it is difficult to implement because the wing hoody that can be opened and closed is too time-consuming to attach and detach the rope.

Even when the seat a or e is stopped by using the hook f (Fig. 8) or the velcro j (Fig. 9), it is not suitable for frequent opening and closing work because it takes time to attach and detach each time the seat is opened and closed. is there.

Further, when the back surface of the seat a is tensioned with the rope d as shown in FIG. 7, the size of the back door is narrowed by the width of the portion q squeezed with the rope d, so that the luggage can be unloaded. There is a problem of inconvenience in work, and these points are problems to be solved.

Therefore, an object of the present invention is to enable a seat to be directly and easily stopped securely and aesthetically on a frame assembled from a pipe material, which is particularly suitable for a wing body and which can be opened and closed. It is an object of the present invention to provide a sheet end treatment material that can be configured to have high sealing performance against intrusion of rainwater or wind.

Means for Solving the Problems As means for solving the above-mentioned problems of the prior art, a sheet end treatment material in a pipe frame according to the present invention is shown in FIG. 1 to FIG. As described above, the semi-circular or U-shaped fitting portion 3 fitted to the outer periphery of the pipe material 2 around which the end of the sheet 1 stretched around the frame assembled with the pipe material 2 is fitted, and the fitting portion. 3 is a kind of mold material having a uniform axial cross-section, which is composed of a flat plate portion 4'extending on one side and a receiving portion 4 formed in a series by bending outward at a substantially right angle. The inner diameter of the fitting portion 3 is made substantially equal to the outer diameter of the pipe material 2 around which the end of the seat 1 is wound,
It is characterized in that it is fitted to the outer periphery of the pipe material 2 around which the end of is wrapped and then fixed to the pipe material 2 with screws 6 or tacks.

An elastic soft material 5 is provided on the outer surface of the receiving portion 4.

Action The fitting portion 3 fitted to the outer periphery of the pipe material 2 around which the sheet 1 is wound closely adheres to the outer periphery of the same sheet 1 and holds the sheet 1 uniformly over the entire surface, and surely stops it aesthetically.

When the frame member such as the openable door is brought into contact with the soft material 5 provided on the receiving portion 4 formed in a series from the flat plate portion 4 ', the cushioning of the frame member and the rainwater or draft Invasion prevention (sealing) is achieved.

Embodiment Next, an embodiment of the present invention shown in the drawings will be described.

1 and 2 show the relationship between the terminal treatment material 10, the pipe material 2 and the sheet 1 according to the present invention. This terminal treatment material
10 is an extruded material of hard vinyl chloride (PVC) that is molded to an average wall thickness of about 2 mm, and is a type of material with a uniform cross-sectional shape in the axial direction, cut into the required length. Used. This terminal treatment material 10 is a sheet 1
A semi-circular fitting part 3 fitted to a pipe material 2 having an outer diameter of about φ28 wound around, a flat plate part 4'extending one side of the fitting part 3 in a tangential direction, and A receiving portion 4 formed by bending a flat plate portion 4'outward at a substantially right angle to form a series.
It consists of and.

The inner diameter of the fitting portion 3 is the outer diameter (φ28) of the pipe material 2 described above.
On the other hand, φ27.2 is formed, which is slightly smaller. Therefore, the fitting portion 3 holds the pipe material 2 in close contact with the pipe material 2 due to its inherent elasticity. Therefore, when the fitting portion 3 is fitted to the outer periphery of the pipe material 2 around which the seat 1 is wound, the seat 1 is strongly held uniformly over the entire surface.
Further, the fitting portion 3 is fixed to the pipe material 2 with a screw (self-tapping bush) 6 (or a tack or the like is also possible).
Therefore, the terminal processing of the sheet 1 is completed.

The semi-circular fitting portion 3 uses the edge portion 7 on the opposite side of the flat plate-shaped receiving portion 4 in a mode in which the position of the contact point of the sheet 1 with respect to the pipe material 2 is used, whereby the fitting portion 3 It is possible for the terminal processing 3 to apply an unreasonable force or deformation to the sheet 1.
Since such a usage mode is premised, the semicircular fitting portion 3 is ideally a semicircle of about 180 °.
However, there is no problem in forming it to slightly smaller than 180 °. Conversely, if it is formed in an arc shape larger than 180 °,
The above-mentioned excessive force and deformation are applied to the sheet 1, and the sheet 1 is easily damaged, which is not preferable. For fixing the fitting portion 3 with the screws 6, it is preferable to screw the screws 6 in the longitudinal direction at intervals of about 50 cm.

The flat plate portion 4'extends from the semicircular position of the semicircular fitting portion 3 to a width dimension of about 20 mm, and is bent outward from the tip portion at a right angle to the receiving portion 4 having a width of about 21 mm. Are formed in series. On the outer surface of the receiving portion 4, a soft material 5 (cushion material or gap seal material) formed of rubber or soft vinyl chloride is attached.

A case where the above-mentioned end treatment material 10 is applied to a wing body in which the frame of the truck shown in FIG. In the relation between the side frame 13 and the rear frame 14 of the wing body which can be freely opened and closed, the above-mentioned end treatment material 10 has the receiving portion 4 at the closed position of the rear frame 14 at a portion of the side frame 13 particularly in contact with the rear frame 14. The rear frame 14 on the back side of
It is used in such a manner that it is in a direction substantially perpendicular to the opening / closing direction (rotational direction) of (Fig. 4). Therefore, the closed side frame 13
In the relationship between the rear frame 14 and the rear frame 14, the rear frame 14 is stopped by abutting against the receiving portion 4 and the soft material 5 of the end treatment material 10 of the side frame 13, and thus has a sealing action for preventing intrusion of rainwater or drafts. It will be demonstrated.

On the other hand, for the terminal treatment of the sheet 1 of the rear frame 14, the terminal treatment material 11 having the configuration without the receiving portion is used. As shown in detail in FIG. 5, the portion from the fitting portion 3 of the end treatment material 11 to the flat plate portion 4 ′ is the receiving portion 4 of the end treatment material 10 used for the side frame 13 and the soft material. 5 is abutted.

The end treatment materials 10 and 11 described above are cut to the length between the joint and the joint of the pipe material forming the side surface frame 13 and the rear surface frame 14 and are used in a portion between the joint and the joint ( (See FIG. 3).

Other Examples (No. 1) In the terminal treatment material 15 shown in FIG. 6, the flat plate portion 4'extending one side of the semi-circular fitting portion 3 and the receiving portion 4 subsequent thereto are made of hard vinyl chloride. It is characterized in that only the fin portion of the tip of the receiving portion 4 is integrally formed with the soft material 5 such as soft vinyl chloride.

(Part 2) Although illustration is omitted, the end of the sheet 1 is wound around the pipe material 2 and a spacer having the same thickness as the thickness of the joint is wound around the pipe material 2, and the end treatment material 10 or It is also possible to fit and stop 11 or 15. In this way, as the end treatment material, for example, the side frame 13 and the rear frame 14 having the same length as the vertical side and the horizontal side are used without causing a problem of the step due to the existence of the joint and the thickness thereof. can do. Therefore, the terminal processing work of the sheet can be carried out easily, and the appearance is further improved.

(Part 3) Similarly, although not shown, when the frame forming the hood is formed of square pipes, H-shaped steel, angles, etc., the fitting parts 3 of the end treatment materials 10 and 11 are used. Can be applied in exactly the same manner as in the above embodiment by forming it in a U shape having a size corresponding to such an aggregate.

Advantageous Effects of the Present Invention As described above in detail with reference to the embodiments, the terminal treatment material for a sheet in a pipe frame according to the present invention is simple in terminal treatment for stopping the end of the sheet 1 to the pipe material 2. Therefore, the appearance can be surely and excellently performed.

Especially, it is suitable for fixing the end of the seat to a frame (frame) that opens and closes like a door. In this case, it has an excellent sealing property to prevent the entry of rainwater and drafts. Can be optimally implemented for the construction of.
