Abstract

PURPOSE:To improve a sealing property in a pillar-like spacer made of an elastic body inserted into a hollow part by forming a plurality of grooves or notches extending in the direction nearly orthogonal to the longitudinal one of the spacer on the outer peripheral surface of the spacer. CONSTITUTION:A plurality of grooves 131-13n are formed on the outer peripheral surface of a pillar-like spacer 13 to extend in the direction nearly orthogonal to the longitudinal direction of the spacer 13. That is, the outer peripheral surface of the spacer 13 is divided to (n+1) thin pieces. Thus, a weather strip 11 makes contacts with the respective upper ends of a rear door glass 1, front door glass 3 and center seal rubber 2 and when the weather strip 11 is pressed, the spacer 13 is formed with a plurality of grooves 131-13n. Since the self-supporting properties of the thin pieces divided longitudinally of the spa are improved, the weather strip 11 follows accurately the shapes of the respective upper ends of both glasses 1, 3 and center seal rubber 2 without producing any gaps therebetween to provide a satisfactory seal.

Description

[Detailed description of the invention] Industrial applications TECHNICAL FIELD This invention relates to automotive weather strips.

2. Description of the Related Art Hollow weather strips are used in window frames and door openings of automobiles to seal the interior and exterior of the vehicle interior.

FIG. 6 shows the VI-V of the case where the weather strip 6 described above is attached to the edge of the vehicle body opening that is opened and closed by the front and rear doors of the four-door hardtop automobile 30 shown in FIG.
It is a sectional view along the I line.

In FIG. 6, the upper edges of the front door glass 3 and the rear door glass l come into pressure contact with a weather strip 6 having a hollow portion 8 to form a seal.
A seal is created by pressing the upper edge in the same manner.

As shown in FIG. 7 and FIG. 8, the center seal rubber 2 has a mounting base 4 having a substantially U-shaped cross section that fits onto the front edge of the rear door glass l, and a mounting base 4 that is attached to the front edge of the rear door glass l. It is roughly composed of a seal lip 5 extending forward and having a hook-shaped cross section, and the seal lip 5 presses against the rear edge of the front door glass 3 from inside the vehicle to seal the space between the two glasses 1.3. It is supposed to be done.

By the way, when both glasses 1.3 are completely closed, the upper end of the center seal rubber 2 protrudes beyond the upper ends of both glasses 1.3 due to its thickness. There will be a difference in level between .3 and .3. Therefore, the weather strip 6 must faithfully follow the shape of the upper end of the center seal rubber 2' that protrudes upward and be in close contact with the upper end of the center seal rubber 2 and the upper ends of both glasses 1.3. This part cannot be reliably sealed.

Therefore, in the past, as shown in FIG.
was moved to the part where it abuts the center seal rubber 2 to seal it (Jikko 5)
6-2579).

Problem to be Solved by the Invention However, since the material of the spacer 7 described above is uniform, the weather strip 6 cannot necessarily follow the shape of the upper end of the center seal rubber 2 faithfully, as shown in FIG. As shown in FIG. 10, which is a cross-sectional view taken along the I was left with a problem.

Means for Solving the Problems Therefore, in order to solve the above problems, the present invention provides a weatherstrip having a hollow part and a columnar spacer made of an elastic body inserted into the hollow part. The spacer is characterized in that a plurality of grooves or notches are formed on the surface thereof and extend in a direction substantially perpendicular to the longitudinal direction of the spacer.

Function: Because the columnar spacer is divided into pieces in the longitudinal direction by the grooves or notches, the above-mentioned 4
For cars with hard-top doors, the front door glass,
The weather strip accurately follows the shapes of the upper ends of the rear door glass and the center seal rubber, and a gap is created between the weather strip and the upper ends of both glasses and the center seal rubber. There is no problem, and it can be sole well.

Example FIG. 1 is a diagram showing an embodiment of the present invention.

In the figure, 13 is a columnar spacer made of an elastic material, for example, sponge; ~131 are a plurality of grooves, and these grooves 13. -13.1 is formed on the outer circumferential surface of the columnar spacer 13 so as to extend substantially orthogonally to the longitudinal direction of the spacer 13. In other words, the outer peripheral surface of the spacer 13 is divided into (n+1) pieces. This spacer 13 has a groove 13 on the side of the weather strip 11 that contacts the center seal rubber 2. It is inserted into the hollow part 12 of the weatherstrip 11 so that the forming surface of ~13fi is located.

Therefore, the weather strip 11 into which the spacer 13 is inserted is attached to the rear door glass 1. Front door glass 3.
in contact with one end of each of the center seal rubbers 2,
When pressed, it becomes as shown in FIG. In this case, the spacer 13 has a plurality of grooves 13. -13. is formed, and the independence of the fragmented parts in the longitudinal direction is increased, so the weather strip 11 accurately follows the shapes of the upper ends of both glasses 1.3 and center seal rubber 2. However, unlike the conventional method, there are no gaps and a good seal can be achieved.

FIG. 2 is a diagram showing a spacer 14 according to another embodiment of the invention.

In the figure, the outer peripheral surface of the spacer 14 has a plurality of grooves 14A extending substantially orthogonally to the longitudinal direction of the spacer 14.
, -14A, and a plurality of grooves 14B1 to 14B extending in the longitudinal direction of the spacer 14 are formed. In other words,
The outer peripheral surface of the spacer 14 is divided into (n+1) x (m+1) pieces. The spacer 14 is inserted into the hollow portion 12 of the weatherstrip 11 so that the surface forming the grooves 14A1 to 14A is located on the side of the weatherstrip 11 that contacts the center seal rubber 2. In the example in FIG. 2, the spacer 14 includes:
Since the grooves 14A, -14A11 and 14B, to 14B are formed, the independence of the individual strips is further enhanced than in the example shown in FIG. , 3. It accurately follows the shape of each upper end of the center seal rubber 2, and there is no gap, making it possible to seal well.

FIG. 3 is a diagram showing a spacer 15 according to still another embodiment of the present invention, and the outer peripheral surface of the spacer 15 has a plurality of notches (slits) 15A extending substantially orthogonally to the longitudinal direction of the spacer 15. .

~15Afi and a plurality of cuts (slits) 15B, ~15B extending in the longitudinal direction of the spacer 15 are formed and separated into (n+t)x(m+1) pieces.

For example, silicon is applied to the outer peripheral surface of the spacer 15 on which the notches 15A and 15A are formed.
This silicon has notches 15A, ~15A11. Cuts 15B1 to 15B.

It is designed to penetrate inside. This is to reduce the sliding resistance between the strips so that each strip can move independently.

Then, this spacer 15 is inserted into the hollow portion 12 of the weather strip 11 in the same manner as in the examples of FIGS. 1 and 2.

In the example shown in FIG. 3 as well, as in the examples shown in FIGS. No generation occurs and seals well.

In addition, in the embodiment described above, the spacers 13 and 14
．． Alternatively, although the plurality of grooves or cuts extend in a direction substantially perpendicular to the longitudinal direction of the spacer 15, the grooves or cuts may extend in a diagonal direction with respect to the longitudinal direction of the spacer.

Effects of the Invention As is clear from the above description, according to the present invention, a plurality of grooves or cuts are formed on the outer circumferential surface of a columnar spacer made of an elastic body, extending in a direction substantially perpendicular to the longitudinal direction of the spacer. As a result, the shape following of the weather strip in the longitudinal direction is improved.For example, the weather strip accurately follows the shape of the upper end of the front door glass, rear door glass, and center seal lano (-). Good sealing can be achieved without creating gaps between the weather strip and the upper ends of both glasses and the center seal rubber.
