A net-pressing rubber having a structure having at least one linear protrusion having a height of 1.5 mm, or (2) continuously extending in the longitudinal direction on the outer peripheral surface of a hollow cord-shaped object. At least two linear protrusions having a height of 0.3 mm to 1.5 mm are provided, and at least one stripe groove-shaped protrusion is continuously provided between the linear protrusions in the longitudinal direction. It is a rubber for net presser having a structure.

The net-pressing rubber according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross sectional view showing an example of an embodiment of the product of the present invention, and FIG. 2 is a cross sectional view showing an example of another embodiment of the product of the present invention. FIG. 3 is a cross-sectional view showing an example of a conventional product.

In FIGS. 1 and 2, 1 is a hollow cord-like object, 2
Is a hollow portion, 3 is a linear protrusion, and 4 is a streak-shaped protrusion. Further, in FIG. 3, 11 is a hollow string-like object, 2
Reference numeral 2 indicates hollow portions, and reference numeral 5 indicates streak-like protrusions. As shown in FIGS. 1 and 2, the net-pressing rubber of the present invention is
On the outer peripheral surface of the hollow string-like object, linear projections 3 extending continuously in the longitudinal direction are arranged via a neck portion 6. The embodiment shown in FIG. 2 has a structure in which at least one streak groove-shaped projection 4 is continuously provided between the linear projections in the longitudinal direction. 1 and 2, the linear projection 3 is shown to have a round cross section, but in the present invention, the cross section of the linear projection 3 has a round shape. In addition, various shapes such as a rhombus, an inverted triangle, an inverted trapezoid, a rectangular shape such as a square shape, and a bell shape can be used.

In the net-pressing rubber of the present invention, the linear protrusions 3 can be easily peeled off from the neck portion 6 and detached, and the net-fixing members provided on the aluminum sash frame for use are fixed. There is an advantage that the linear protrusions 3 can be appropriately peeled off and used according to the groove width of the grooves. Therefore, the outer diameter of the hollow cord 1 is set to an outer diameter substantially corresponding to the currently widely used minimum groove width, and the total thickness of the net-pressing rubber including the height of the linear protrusions 3 ( diameter)
Is thick enough to accommodate the maximum groove width. Therefore, the height of the linear projection 3 is usually 0.3 mm to 1.5 mm, preferably 0.5 m.
It is desirable to set it to m-0.7 mm.

Further, at least one linear projection 3 is provided on the outer peripheral surface of the hollow cord 1, but it is preferable to provide two or more, more preferably three or more, and more preferably 5 It is particularly preferable to provide 6 to 6. Linear protrusion 3
The outer diameter and the linear shape of the hollow cord-shaped material 1 are such that the thickness of the entire net-pressing rubber including the height of the linear protrusions 3 corresponds to the maximum groove width of the net-fixing net groove. Although it is determined by the shape, size (height), etc. of the protrusions 3, 3 to 9 are generally preferable ranges. In the embodiment shown in FIG. 1, that is, in the structure in which only the linear protrusions 3 are provided on the outer peripheral surface of the hollow cord 1, the height of the linear protrusions 3 is adopted in the present invention. It is preferable that the height of the net is relatively high from the viewpoints of the net holding function and the action and effect.

In the embodiment shown in FIG. 2, that is, in the structure in which the line-shaped projections 3 are formed between the linear projections 3, the shape of the line-shaped projections 4 is a mountain-shaped cross section. Is preferred. It is desirable that the height of the peaks of the stripe groove-shaped projections 4 is usually about 0.2 mm to 1.0 mm. Further, the number of the linear groove-shaped projections 4 differs depending on the number of linear projections 3, and when the number of linear projections 3 is small, the linear grooves arranged between the linear projections are provided. The number of protrusions 4 is relatively large. When the net is pushed into the net-fixing net groove, the streak-like projections 4 further increase the frictional resistance with the net along with the linear projections 3 and more firmly prevent the net from slipping through the net groove. The structure shown in FIG. 2 is a preferred embodiment because it has the effects. In the case of the structure shown in FIG. 1, when the linear protrusions 3 are peeled off from the neck portion 6, the remaining neck portion and the remaining linear protrusions 3 form a net pushed into the mesh groove. Since it acts so as to exhibit frictional resistance, the net does not easily slip through the net groove.

Usually, when the net is pushed into the net-fixing net groove, the net-pressing rubber is twisted and pushed into the net groove while the hollow portion 2 is crushed. The net presser rubber according to the present invention is a rubber,
A soft synthetic resin, for example, a soft and elastic material such as soft vinyl chloride is generally used. In the rubber for net-pressing according to the present invention, the hollow cord 1 itself and the linear protrusions 3 provided on the outer peripheral surface thereof are soft and elastic, and the neck portion 6 is also the same material and is soft and elastic. Since the linear projection 3 easily falls down at the neck portion 6,
The work of pushing the net into the net groove is easy. On the other hand, after being pushed into the mesh groove, the elasticity of the material causes the mesh to be pushed into the groove, so that the linear protrusions 3 are pressed into the mesh and prevent the mesh from sliding through the mesh groove. It has the effect of, and can firmly fix the net.

The net-pressing rubber of the present invention can be easily molded by an extrusion molding method. That is, by extruding a molten material such as vinyl chloride resin into a string shape from a hollow ring molding die equipped with a groove for forming the linear protrusions 3 attached to the tip of an ordinary extruder. It can be molded. Further, by providing the streak groove in the outer peripheral portion molding portion of the hollow ring molding die, the streak groove-shaped projection 4 can be formed on the outer peripheral surface of the hollow cord-shaped object 1.
