Abstract

(57) [Abstract] [Purpose] A plurality of valleys are formed in a pleated shape along a bent portion of a plurality of plates 3 formed by cutting a thin sheet material so as to form a square bent portion, and an inner peripheral surface on a narrow angle side. Cloth cover 2
When the valleys are welded along the inner peripheral surface of the plate 3, a protrusion is formed at the corner of the cloth cover 2 facing the corner of the plate 3, but in order to avoid interference between the protrusion and the plate. , A relief part is provided on the plate, and the cloth cover 2 is provided.
The interference between the projecting portion 2a and the plate 3 opposed thereto is prevented. The valley portion of the cloth cover is formed along a plurality of plates formed by cutting a thin sheet of thermoplastic resin into a band shape so as to form a square bent portion, along the bent portion and the inner peripheral surface on the narrow angle side. When welding along the inner peripheral surface of the plate, the plate 3
A protrusion is formed at the corner of the cloth cover 2 opposite to the corner of the cover, but in order to avoid interference between the protrusion and the plate, a relief portion is provided on the plate, so that the bellows with a foldable cloth-foldable outer surface plate is provided. Is configured.

Description

[Detailed description of the invention]

The present invention mainly relates to a cover used as a protective cover for a sliding portion of a machine tool and other general industrial machines.

Conventionally, as a folding bellows made of a square cloth, a pleated fold is formed by attaching a reinforcing material to the inner side of a bellows of a glued cloth formed with pleated valleys, and a reinforcing bellows on the inner side of the bellows. Plates are known which are welded. According to the present invention, the inside of a cloth cover having a plurality of peaks and valleys in a pleated shape (hereinafter referred to as a cloth cover) is not attached with the above-mentioned reinforcing material or plate, and the thermoplastic resin is formed along the outer peripheral surface of the cloth cover. It is a bellows with a foldable outer plate made of a resin formed by welding the inner peripheral surface of a U-shaped, L-shaped, Z-shaped or other cut plate made of resin (hereinafter referred to as the bellows of the present invention). The present invention will be described below with reference to the drawings.

FIG. 1 is a partial perspective view of the bellows 1 of the present invention. FIG. 2 is a partial perspective view of the cloth cover. FIGS. 3-1A, 2A, 3A and FIGS. 3-1B, 2B, 3B show front views of the plate. A protruding portion 2a is formed by folding the cloth cover 2 at each valley corner A in the partial perspective view of the cloth cover 2 of FIG. In the front views of the plates shown in FIGS. 3-1A, 2A, 3A and FIGS. 3-1B, 2B, 3B, a relief portion 3a is provided at each inner corner portion. The bellows 1 of the present invention includes a plurality of plates 3 and a cloth cover 2.

[0004] Along the valley straight portions C1 and C2 on the outer peripheral surface of the cloth cover 2 and opposed thereto, the straight portions E1, E2 and E3 of the plurality of plates 3 (L-shape in FIGS. 3-2A and 2B). In the case of (1), the bellows with a foldable outer surface plate are formed by welding each of E1 and E2) with the protruding portion 2a of the cloth cover 2 inserted into the relief portion 3a of the plate.

Claims (1)

[Utility model registration claims] 1. A woven cloth is formed of a thermoplastic resin along a bent portion and an inner peripheral surface on a narrow angle side of a plurality of plates formed by cutting a thin sheet of thermoplastic resin into a band shape so as to form a square bent portion. In the bellows with a foldable outer surface plate made of cloth, the valley portion forming the valley of the cloth cover formed with a plurality of valleys in a pleated shape is welded along the inner peripheral surface of the plate. The valley portion of the cloth cover having the valley formed therein is welded to the linear portion of the inner peripheral surface of the plate, and the valley is formed along a corner portion where the straight line of the inner peripheral surface intersects with the straight line. When the folded cloth cover is folded, a corner folded portion of the cloth cover projects from a corner of the plate between adjacent valleys having a corner from one valley of the cloth cover. With the protrusion of the cloth cover , So that it does not interfere with the corner of the plate facing it,
A bellows with a foldable outer plate made of cloth, characterized in that a relief portion is provided at a corner portion of an inner peripheral surface of the plurality of plates to avoid interference with the projecting portion.
