Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a structure of an end portion of a shutter case.

[0002]

2. Description of the Related Art An ordinary shutter case has a case main body and brackets provided on both right and left ends of the main body.
By providing covering covers positioned on the left and right sides of the case, the end of the case and the entire bracket are covered, thereby ensuring the appearance and safety of the shutter curtain.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a shutter case having a structure different from that of a conventional shutter case. Although the cover case is not provided, the left and right ends of the case body are not exposed. It is another object of the present invention to provide a shape of the end portion of the shutter case which is excellent in design.

[0004]

The technical means adopted by the present invention to achieve the above object is to provide a case upper plate, a case lower plate, and a case upper plate and a case lower plate at both ends in the longitudinal direction. In the shutter case constituted by the provided left and right brackets, a resin edge cover is provided at both longitudinal edges of the case upper plate and the case lower plate.

Preferably, both ends in the length direction of the upper case plate and the lower case plate have extra ends projecting beyond the surface of the bracket, and the resin edge cover is provided with the extra end. It is provided so as to cover the part. Further, the resin edge cover has opposing long holding sides and short holding sides, and the dimension of the short holding sides is substantially the same as the extension dimension of the extra end portion. A first abutting portion and a second abutting portion are respectively formed at the distal end portions of the long sandwiching side and the short sandwiching side, and a third abutting portion is formed on the inner wall of the long sandwiching side. The resin edge cover is sandwiched between the edges of the case via three contact portions.

[0006] The present invention further provides a resin corner cover at the meeting portion between the case upper plate and the case lower plate at both end edges in the longitudinal direction of the case upper plate and the case lower plate. It is characterized by having been provided. In one preferred form, the case upper plate and the case lower plate are fixed to a case angle supported between the left and right brackets.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a shutter device. The shutter device includes a guide rail 1 erected on the left and right sides of an opening, a winding shaft 2 provided above the opening,
It includes a shutter curtain 3 wound or unwound on the winding shaft 2, and a shutter case that houses the winding shaft 2 and the shutter curtain 3 wound on the winding shaft 2.

The shutter case body is composed of a long case upper plate 4 and a long case lower plate 5,
A wiring side bracket 6 and a driven side bracket 7 are provided on both left and right sides of the shutter case body, respectively. A take-up shaft 2, two case angles 8, 9 and an outer lintel 10 and an inner lintel 11, which constitute a lintel portion, are supported between the left and right brackets 6, 7. The case angle 8 on the skeleton side is provided with a plurality of rib-like supports 12 at desired intervals in the length direction. The rib-like support body 12 is a so-called case-reinforced bent which supports the flexible angle 9 and the case upper plate 4.

The case upper plate 4 constituting the upper surface of the shutter case is composed of a mounting portion 4a on the skeleton side, a gentle inclined surface extending forward from the skeleton side, and an inclined surface having a slightly steep gradient. The formed upper surface portion 4b and the upper surface portion 4
and a stepped portion 4c integrally formed at the distal end portion b. The step portion 4c is formed in a step shape from the first bent side 40a, the second bent side 40b, and the third bent side 40c.

The case lower plate 5 constituting the lower surface of the shutter case includes a mounting portion 5a on the skeleton side, a lower surface portion 5b extending forward and upward from the skeleton side in an arc shape, and a lower surface portion 5b.
and a bent portion 5c integrally formed at the distal end portion b.

The other case angle 9 separated from the skeleton side is arranged at a position corresponding to the stepped portion 4c and the bent portion 5c of the case upper plate 4 and the case lower plate 5, respectively.
The locking portions 4c, 5c are each configured to be supported by the case angle 9. Specifically, as shown in FIG. 2, the first bent side 40a of the case upper plate 4 and the case lower plate 5
The upper end side (near the bent portion 5c) of the lower surface portion 5b is fixed to the case angle 9 via a screw.

As shown in FIG. 5, both end portions of the case upper plate 4 and the case lower plate 5 in the longitudinal direction slightly protrude from the surface portions of the brackets 6 and 7, and extra extension ends 13 and 14 are formed. ing. An upper resin edge cover 15 and a lower resin edge cover 16 are provided around both ends of the case upper plate 4 and the case lower plate 5 in the longitudinal direction, that is, the extra ends 13 and 14.

As shown in FIGS. 5A and 6A, an upper resin edge cover 15 and a lower resin edge cover 16 are provided.
Are formed of elongated members having shapes corresponding to the shapes of the edges of the case upper plate 4 and the case lower plate 5, respectively, and are provided around substantially the entire area of the edges. The upper resin edge cover 15 has a shape corresponding to the upper surface portion 4 b of the case upper plate 4, and the lower resin edge cover 16 has a shape corresponding to the lower surface portion 5 b of the case lower plate 5. And a resin corner cover 17 is provided at the meeting site of the locking portion 4c of the case upper plate 4 and the locking portion 5c of the case lower plate 5. is there.

In particular, as shown in FIG. 5B, the resin edge covers 15 and 16 are provided with opposing sandwiching sides 18a and 18b each composed of a long side and a short side.
A first contact portion 18c and a second contact portion 18d are formed on one end side of b, and the other end side is continuously integrated. A protruding third contact portion 18e is formed on the inner wall of the elongated holding side 18a. Therefore, the resin edge covers 15 and 16 are satisfactorily sandwiched or fitted to the extra extension ends 13 and 14 via the three contact points 18c, 18d and 18e. It is preferable that the protruding dimension of the extended end portions 13 and 14 with respect to the surface portions of the brackets 6 and 7 is as small as possible. Therefore, the dimension of the short holding side 18b is small. In order to satisfactorily sandwich the extra ends 13 and 14 using the edge covers 15 and 16 having the relatively short short sandwiching sides 18b, the long sandwiching sides 18a are employed.
It was made to clamp at three points.

A continuous inclined guide surface 18f is formed between the first contact portion 18c and the third contact portion 18e on the inner wall of the elongated sandwiching side 18a.
5 and 16 can be clamped satisfactorily. The outer peripheral surfaces of the edge covers 15 and 16 form a curved surface,
The outer peripheral surface does not form an acute corner.

As shown in FIG. 7, the resin corner cover 17 has side walls 17a, a front wall 17b, a rear wall 17c,
And a lower wall 17d. The front wall 17b is the slope 1
70a, first vertical portion 170b, horizontal portion 170c, second vertical portion 1
70d, it is formed in a stepped shape, and has a shape corresponding to the stepped locking portion 4c of the case upper plate 4. An adhesive tape 19 is provided on the inner wall of the second vertical portion 170d of the front wall 17b.
Are provided so as to be easily attached to both longitudinal edges of the case upper plate 4 and the case lower plate 5.

[0017]

According to the present invention, there is provided an end structure of a shutter case in which the end portion of the shutter case is not exposed, and therefore, is excellent in safety or rust prevention and is also excellent in design. be able to.
