Description

[Detailed Description of the Invention] The present invention relates to a structure for retaining the end of a woven fabric when the woven fabric is fixed to a rigid body.

A conventional woven fabric retaining structure is shown in FIG. 1st
In the figure, 1 is a woven fabric, 2 is a rigid body, and 3 is an adhesive.The woven fabric 1 is sandwiched between the grooves 21 to which the rigid body 2 is attached, and the gap between the grooves 21 is filled with the adhesive 3. was fixed to rigid body 2.

However, when used in water, oil, etc., the adhesive strength of the adhesive may decrease, and
When longitudinal tension is applied to the woven fabric 1, a large bonding area is required, and considerations such as making the grooves 21 deep are required, resulting in a disadvantage that the rigid body 2 becomes large.

The present invention was developed in order to eliminate these drawbacks, and the opposite sides of each cross section are inclined with respect to the length direction of the woven fabric, and the woven fabric is sandwiched between them and fixed by tightening to a rigid body. Under water,
To obtain a woven fabric end retaining structure that can sufficiently withstand tension in the longitudinal direction as well as in oil. This will be explained in detail below.

FIG. 2 is a sectional view showing an embodiment of the present invention. In the figure, 22 is a cylindrical rigid body having a notch 23 on the shoulder, to which the cylindrical woven fabric 1 is to be fixed. 4 is a ring-shaped retaining member having a slope 41 inclined at a predetermined angle with respect to the length direction of the woven fabric in its cross-sectional shape;
The end portion of the woven fabric 1 is wrapped around the retaining member 4. 5 has a slope 51 opposite to the slope 41 of the retaining member 4, and the end of the woven fabric 1 is clamped and fixed between the two slopes 41 and 51, and is secured by a tightening part 52 such as a screw. It is fastened and fixed to the rigid body 22. Woven fabric 1
To fasten it to the rigid body 22, first wrap the end of the woven fabric 1 around the fastening member 4, place it in the shoulder notch 23 of the rigid body 22, and tighten it from above with the fastening tool 5. By fixing, the end portion of the woven fabric 1 is clamped under pressure between the slopes 41 and 51. As a result, the woven fabric 1 is firmly fixed and retained on the rigid body 22.

As explained above, since no adhesive is used in this embodiment, the adhesion strength between the woven fabric 1 and the rigid body 22 does not decrease even in water or oil.
Furthermore, since the retaining member 4 and the fastening fastener 5 have slopes 41 and 51, when tension is applied in the length direction, the contact pressure between the retaining member 4 and the fastening fastener 5 increases according to the tension. Therefore, the woven fabric 1 can be held in place more reliably. Therefore, if the retaining member 4 and the fixing fastener 5 have appropriate strength, the woven fabric 1, the retaining member 4 and the fixing fastener 5
This has the advantage that even if the contact area with the rigid body 22 is small, it can withstand a large tension, and the rigid body 22 can be made smaller.

FIG. 3 is a sectional view showing another embodiment of the present invention, which differs from the previous embodiment in that the fixing fastener is composed of a fixing member 6 and a tightening member 7, which are separate members. This fastening member 6 has a slope 61 which acts exactly like the slope 51 of the fastening fastener 5, and the fastening member 7 has a fastening part 71 which acts exactly like the fastening part 52 of the fastening fastener 5. have.

By configuring in this way, the tightening portion 71
Even if the screws are used, there is some slippage when tightening and fixing because the tightening member 7 and the fixing member 6 are not integrated, and the two slopes 41 and 61
This prevents force in the shear direction from being applied to the woven fabric 1 sandwiched between.

As explained in detail above, the present invention uses a retaining member having an inclined surface and a fixed fastener, so that the fabric can withstand tension in the longitudinal direction without causing local breaks. Since no adhesive is used, it can be used in water, oil, etc. Furthermore, in this example, the shape of the contact surface between the woven fabric and the rigid body is a curved surface like the side surface of a truncated cone, but if the woven fabric to be held back is a flat cloth, the above-mentioned holding member It is clear that the fabric can be fastened in a similar manner to a given rigid body by means of suitable fastening fasteners, provided that it is rod-shaped and has the above-mentioned cross-section.
