Description

Spacer for integrated roof rack banding and integrated roof rack banding method using same {spacer for banding of one body type roof lack and method for banding of one body type roof lack using the same}

The present invention relates to an integrated roof rack banding spacer and an integrated roof rack banding method using the same. More particularly, the cross-sectional shape of both ends of the integrated roof rack body at the time of bending can be minimized by minimizing the change in cross-sectional shape when bending both ends of the integrated roof rack body. The present invention relates to an integrated roof rack banding spacer and an integrated roof rack banding method using the same.

In general, passenger cars other than freight cars have limited internal spaces, and therefore, there are restrictions on loading cargo.

For this reason, a loading space is further secured by attaching a roof carrier as disclosed in Korean Patent Laid-Open Publication No. 10-1997-0038757 (published date: July 24, 1997) on the roof panel of a general passenger vehicle.

The roof carrier includes a pair of roof racks installed in the longitudinal direction on both sides of the roof panel, and a plurality of crossbars coupled between the roof racks, and having various sizes of cargo loaded thereon as the distance between the crossbars is adjusted. Is possible.

On the other hand, conventional roof racks were generally manufactured in a split type.

That is, the conventional split roof rack is manufactured by assembling the separately formed main body, the pad, the suspension, the cover, and the like.

Such a conventional split roof rack can increase the design freedom as the cover is manufactured in various colors and shapes.

However, the conventional split roof rack is composed of a relatively large number of parts of about 10 kinds, especially the assembly of the front and rear ends of the body and the cover coupling to each of the stents, which takes a considerable time to assemble the product, the efficiency of assembly work There was a problem of this deterioration.

In order to solve the above problem, an integrated roof rack has been proposed.

The integrated roof rack includes a main body, a pad, and the like. As the main body includes a stent and a cover function, the integrated roof rack is composed of approximately four types of relatively few parts. The efficiency of the product assembly work can be improved.

Meanwhile, the conventional integrated roof rack manufacturing method includes an integrated roof rack body molding step of extruding an integral roof rack body in a tubular shape through an extruder, and an integrated roof rack body banding step of bending front and rear ends of the extruded integrated roof rack body with a predetermined curvature; And an integrated roof rack body cutting step of cutting the front and rear end lower ends of the banded integrated roof rack body, and an integrated roof rack body cutting step of cutting the cutting surface of the integrated roof rack body.

In the conventional integrated roof rack manufacturing method, the bending of the integrated roof rack main body is carried out by seating the extruded integrated roof rack main body on a bending die formed at both ends of the upper surface of a curved surface with a constant curvature, and then pressing both ends of the integrated roof rack main body in a seating state. It was to bend to a curvature corresponding to the curvature of both end surfaces of the upper surface.

However, when the bending curvature of the integrated roof rack body is to be made relatively small, that is, when the curvature of both ends of the upper surface of the bending die is relatively small, the cross-sectional shape of both ends of the integrated roof rack body that is bent by pressing, that is, in FIG. As shown, since the distortion of the cross-sectional shape of both ends of the integrated roof rack body 100 is generated, there is a problem that a defective product is generated.

For this reason, the relevant field seeks to minimize the cross-sectional shape change of both ends of the integrated roof rack body in the bending process of the integrated roof rack, thereby preventing the occurrence of defects caused by the cross-sectional shape change of both ends of the integrated roof rack body. However, until now, the situation has not been satisfactory.

The present invention has been proposed in view of the above situation, and when the conventional curvature of the integrated roof rack banding to reduce the bending curvature of the integrated roof rack body relatively, due to the cross-sectional shape of both ends of the integrated roof rack body banded by pressing failure An object of the present invention is to provide an integrated roof rack banding spacer and an integrated roof rack banding method using the same.

Each of the divided pieces has a groove portion on one surface, and a protrusion having a shape corresponding to the groove portion on the other surface opposite to the groove portion.

Each of the split pieces has a through hole for insertion of the elastic member and the link member.

The elastic members are fixed to the foremost and rearmost split pieces, each of which has both ends in the longitudinal direction adjacent thereto.

The elastic member is disposed to face each other with the link member therebetween.

The link member has a ring at the front end and a round jaw at the rear end.

The ring is detachably formed from the front end of the link member.

The ring is connected with the wire.

The link member is formed to have a length from the rear of the front end of the ring to the front of the rear tip of the rear tip is longer than the length of the divided pieces arranged in one direction.

The link member is formed of a flexible material.

The integrated roof rack bending method using the integrated roof rack bending spacer according to the present invention includes a spacer preparation step of preparing a spacer for the integrated roof rack bending; A spacer insertion step of inserting the spacer into both ends of the through hole of the integral roof rack body extruded; An integrated roof rack body seating step of seating the integrated roof rack body into which the spacer is inserted, on an upper surface of a bending die; And an integrated roof rack body pressing step of pressing both ends of the integrated roof rack body mounted on the upper surface of the bending die.

The main body pressing step may further include a spacer separating step of separating the spacer from the integrated roof rack body by pulling a wire connected to a ring provided at the front end of the link member of the spacer.

In the integrated roof rack banding spacer and the integrated roof rack banding method using the same according to the present invention, each of the plurality of divided pieces arranged in one direction is elastically supported by an elastic member while being formed in the same shape as the through hole of the integrated roof rack body. When both ends of the integrated roof rack body are pressed in the state in which the split pieces combined with the elastic member and the link member are inserted at both ends of the integrated roof rack body, the cross-sectional shape of both ends of the integrated roof rack body is maintained intact by the support of each of the split pieces. Therefore, it is possible to prevent the occurrence of defects due to the cross-sectional shape change of both ends of the integrated roof rack body.
