Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an end cap attached to an end face of a blind head box having an open top.

[0002]

2. Description of the Related Art Conventionally, an end cap of a blind head box has an end plate shaped to cover and seal the end surface of the head box, and a fixing portion projecting from the end plate along the inner bottom surface of the head box. And a screw through hole communicating with the bottom of the head box, a set screw was inserted from under the head box, and a fastening plate was screwed into the set screw to fix the end cap to the head box.

[0003]

When the end cap is fixed by a set screw passing through the lower surface of the head box, the head of the set screw is exposed to impair the appearance, and the slat is caught on the head of the set screw that protrudes. Could be damaged. The present invention has been made to solve this problem, and an object of the present invention is to provide an end cap of a head box in which a set screw is not exposed from under the head box.

[0004]

In order to achieve the above-mentioned object, means adopted by the present invention is a protruding ridge extending at least in one set of opposing directions and extending in a longitudinal direction on an upper portion of front and rear inner surfaces of a head box. The end plate of the end cap is integrally provided with an upper plate protruding along the upper surface of the ridge, and a set screw passed through the upper plate is screwed into the tightening plate, and the end cap is attached to the end surface of the head box. It has been fixed to.

[0005]

When a set screw is inserted into the set screw through hole of the upper plate and the set screw is loosely screwed into the tightening plate, an upper and lower gap is generated between the upper plate and the tightening plate that is larger than the vertical width of the ridge. In this state, when the end face plate is brought into contact with the end face of the head box, the ridge enters between the upper plate portion and the fastening plate. Then, when the set screw is screwed tightly, the upper plate and the tightening plate hold the ridge, and the end cap is fixed to the end face of the head box. The set screw is located in the opening at the top of the headbox and is not visible from the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An end cap according to the present invention will be described based on an embodiment shown in the drawings. As shown in FIG. 1, the end face plate 11 of the end cap 10 has a shape that completely covers the end face of the head box 20 from the outside. The head box 20 is open at the top, and has opposed ridges 21 and 21 ′ at the top of the front and rear inner surfaces. An upper surface plate portion 12 protrudes from the end surface plate 11 along the upper surfaces of the ridges 21, 21 '. Between the ridges 21, 21 ', the top plate 12
The two setscrews 13, 13 ′ are passed through the
′ Is a fastening plate 14 located below the ridges 21 and 21 ′,
Screw into 14´. The fitting portion 15 protrudes from the end face plate 11 along the inner surface of the head box 20. The fitting portion 15 has a hollow shell shape, and has grooves 16 and 16 for receiving set screws 13 and 13 ′ on its upper surface.
'. The upper surface of the fitting portion 15 is in contact with the lower surfaces of the fastening plates 14 and 14 ', and is connected to the upper plate portion at the center.

As shown in FIG. 2, an upper plate 12 protruding from an end face plate 11 of an end cap 10 and a fitting portion 15 have the same protrusion length. The upper plate 12 has two slots 1
Open holes 7 and 17 'and set screws 1 as shown by the arrows.
Insert 3 and 13 '. The setscrew 13, 13 ′ is screwed into the screw holes 18, 18 ′ of the fastening plates 14, 14 ′ arranged on the upper surface of the fitting portion 15. With the set screws 13, 13 'loosely screwed in, they are fitted to the end face of the head box 20 shown in FIG. At this time, as shown in FIG. 1, a gap larger than the vertical width of the projections 21 and 21 'is formed between the upper plate 12 and the fastening plates 14 and 14'. , 21 ′, the fitting portion 15 has a projection 21, 21 ′.
And smoothly fit along the inner surface below. Then, when the setscrews 13 and 13 'are tightened firmly, the upper plate 12 and the tightening plates 14 and 14' hold the protruding portions 21 and 21 'and the end cap
10 is fixed to the head box 20. If the set screws 13 and 13 'are loosened, the end cap 10 can be easily
Can be removed from. Since the set screw is located in the upper opening of the head box 20, it is not visible from the outside.

[0008]

[Effect of the Invention] As described above, the end cap of the present invention is different from the conventional one in which the fixing screw is passed from under the head box, and the fixing screw is passed from the upper opening of the head box. Therefore, there is an excellent effect that the head of the set screw is visible from the outside and the appearance is impaired, and that the slat is not caught by the head of the set screw and is not damaged.
