Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a joining means of a main body block for a gutter having a lid step and a lid block.

[0002]

[Prior art]

 The conventional joining of the main body block for the gutter having the lid step and the lid block is such that the lid block is directly mounted on the lid step, so that the process of hanging and removing the lid is easy. In particular, the lid stuck to the step over time, and removing the lid required a great deal of labor. In addition, if there is play, noise is generated by the load of the traveling vehicle, etc., which has caused the model to lose shape.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of such a conventional situation, and the main body-side lid step and the lower surface of the lid are connected to each other by the corresponding line contact floating joint. Provide a gap between the main block for the gutter and the lid block, which has a clearance between them, has excellent workability for hanging and removing the lid, is adaptable to shape collapse during use, and has a noise prevention effect. It is assumed that.

[0004]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, inclined recesses 3 are provided at predetermined intervals in both inner lid steps 2 of the main body block 1 for gutters. On the other hand, on the lower surface 4a of the lid block 4 corresponding to the inclined recesses 3, there is provided an inclined projection portion 5 having a steeper angle than the inclination angle of the inclined recess portion 3. The gutter main body block and the lid block have a clearance S between the main body side lid step and the lid lower surface by line contact floating joining between the inclined protrusion 5 and the inclined concave part 3. It is a joining device.

Contrary to the above, inclined projections 6 are provided at predetermined intervals on both inner lid steps 2 of the side groove main body block 1, and the lower surface 4 a of the lid block 4 corresponding to the inclined projections 6 is provided on the lower surface 4 a. An inclined concave portion 7 having a gentler inclination than the inclination angle of the inclined protrusion portion 6 is provided, and a line contact floating joint between the inclined concave portion 7 and the inclined protrusion portion 6 allows a gap between the main body side lid step portion and the lid side lower surface. This is a joining device for a gutter main body block and a lid block capable of holding a clearance S at the same time.

[0006]

[Action and effect of the invention]

 Since the present invention is configured as described above, the lid block 4 and the main body block 1 are connected to each other by joining the inclined projections 5 to 7 and the inclined recesses 3 to 6 respectively. As shown in FIG. 2 and FIG. 3, as a result, the clearance S can be maintained between the main body side lid step and the lid side lower surface.

[0007] The floating joint holding the clearance S improves the workability of hanging and removing the lid. More specifically, in the case of the cover hanging, it is possible to carry out the construction smoothly by the unevenness guide action of the inclined protrusion 5 and the inclined concave portion 3, and in the case of the cover removal, there is no sticking due to the close contact placement (surface contact), thereby saving labor. Can be constructed.

[0008] Unlike the conventional method in which the lid block is directly mounted on the lid step portion, no backlash occurs, and the strength against load is sufficiently maintained. Even if the shape collapses during use, adaptability is high due to the line contact part. In general, an excellent noise prevention effect can be obtained.

[0009]

[Embodiment of the invention]

 In FIG. 1, reference numeral 1 denotes a side groove main body block having a lid step, and four inverted pyramid-shaped inclined recesses 3 are arranged on both inner lid steps 2 for each lid block. On the other hand, on the lower surface 4a of the lid block 4 at a position corresponding to the inclined concave portion 3, an inclined pyramid-shaped inclined projection portion 5 having a steeper inclination than the inclined angle of the inclined concave portion 3 is provided. And joining the inclined groove 3 and the inclined protrusion 5 to each other by a line contact floating joint so that a clearance S can be maintained between the body side lid step and the lid lower surface. Device.

Contrary to the above, reference numeral 1 denotes a side groove main body block with a lid step, and four pyramid-shaped inclined projections 6 are arranged on both inner lid steps 2 for each lid block. I do. On the other hand, a pyramid-shaped inclined concave portion 7 having a gentler inclination than the inclined angle of the inclined protrusion 6 is provided at a position corresponding to the inclined protrusion 6 on the lower surface 4 a of the lid block 4. The gutter body block and the lid block, which are capable of maintaining a clearance S between the body side lid step and the lid lower surface by the line contact floating joint between the inclined recessed part 7 and the inclined projection part 6. Device.
