Description

[Detailed Description of the Invention] The present invention relates to a roof carrier that is attached to the roof of an automobile.

The purpose of the present invention is to provide a roof carrier that can be easily and freely operated without the need for tools to adjust the length of the roof carrier, and that can be firmly fixed after adjustment. be.

Another object of the present invention is to eliminate protrusions such as bolts from the expansion/contraction adjustment part, to prevent the roof of the automobile from being damaged by these protrusions, and to provide an automobile roof carrier that has an excellent appearance. This is what we are trying to provide.

2. Description of the Related Art Roof carriers (also referred to as ski carriers), which are mounted on the roof of an automobile to carry skis and other long objects, have been widely known.

These roof carriers were developed in the 1970s to provide versatility that can be applied to any of a variety of vehicles with different interiors.
As seen in Figure 1 of Publication No. 9-50935, a telescopic rod (intermediate tube) is interposed between the rods forming the main body of the carrier, and when used, it matches the width of each vehicle, especially the roof width. After adjusting the expansion and contraction as described above, the rod forming the main body of the carrier and the telescopic rod are fixed together using a tightening tool such as a bolt.

However, according to these conventional methods, spanners and other tools are always required to bolt the carrier body and the telescoping rod, and the heads of these fixing bolts protrude outward. It has disadvantages such as poor appearance and the possibility of damaging the roof coating.

The purpose of the present invention is to eliminate these drawbacks, and the purpose has been completely achieved by completing the invention described below.

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

1.1 is a carrier body consisting of a cylindrical metal rod,
A telescopic rod 2 is slidably fitted in the central portion, and leg rods 3, 3 for attachment are integrally attached to the ends.

4, 4 is a lock cylinder for fixing the telescopic rod 2 and the carrier main body 1, and on the inside of the cylinder there is a marking that matches the thread 11 carved on the end of the carrier main body 1. 41 is engraved, and the end portion is formed into a tapered reduced diameter portion 42 whose diameter is slightly smaller than that of the marking 41 portion.

Reference numeral 5 denotes a locking sleeve that is fitted onto the outer surface of the telescopic rod 2, and the portion other than the thick proximal end portion 51 has a thickness that allows it to be inserted into the carrier main body 1 together with the telescopic rod 2. The wall thickness is slightly smaller than the outer diameter of the main body 1, and a diameter reducing slit 52 is provided along the length direction.

6 is a hook for locking the tightening string 7, and the hook 6 has an inverted U shape.
The base except for 1.61 is loosely fitted inside the lock cylinder 4 so as to be freely rotatable.

It is desirable that the outer periphery of the inner lock cylinder 4 be knurled for convenient operation.

Since the present invention is constructed as described above, when installing it on the roof of a car, the lock cylinders 4, 4 are released, and the telescopic rod 2 is tightened.
If the leg rods 3, 3 at the ends of the carrier main body 1 are attached to the rain gutter in a state in which the carrier body 1 can freely slide, the length can be adjusted instantly and easily.

Next, when the lock cylinders 4, 4 are tightened, as they rotate, the lock sleeve 5 is sequentially compressed by the tapered diameter-reduced portion 42 formed inside the cylinders, and the outer periphery of the telescoping rod 2 is firmly gripped. It can be fixed in place, and it is so simple that these operations do not require any tools at all and can be completed with just the fingers.

In addition, the lock cylinder 4 of the present invention is made by screwing means by screwing together the thread 11 carved on the end of the carrier main body 1 with the marking 41 carved on the inside of the cylinder. Unlike the above-mentioned known example, there is no need for a bolt for fixing, and the protruding parts associated with this can also be eliminated, thereby reducing the damage to the vehicle body during operation that conventionally occurred when using a bolt. It has the characteristics of not only being able to be made completely unique, but also having a smart appearance and full of functional beauty.
