Description

[Detailed Description of the Invention] The present invention relates to an extension device for a box frame of a curtain, a blind, etc., and more specifically, an end face of a box frame of a plurality of curtain boxes etc. that is provided with engagement grooves at the top, bottom or side along the longitudinal direction. For box frames such as curtains, blinds, etc., which extend the box frames by abutting them in series or in a bent manner, and connecting the two box frames at the abutting portions through a connecting tool that engages with the engagement grooves of both box frames. Relating to an extension device.

Generally, a box frame for suspending curtains, blinds, lighting equipment, etc. is constructed by connecting and extending a plurality of box frames in the longitudinal direction. In this case, at the abutting portions of the adjacent box frames, a joint member having a cross-sectional shape approximately equal to the inner shape or shape of these box frames is fitted inside or outside of the abutting portions of the two adjacent box frames. In many cases, connections can be extended by combining them. However, with this type of extension device, there are molding errors and construction errors in the joint members and box frames, so even if it is possible to position the center of both box frames, it is difficult to adjust the vertical direction of both box frames. It has not been possible to prevent such positional displacement. If such a positional shift occurs in the vertical and width directions of both box frames, not only will the curtains, blinds, etc. not be able to operate smoothly, but there is also a risk of damaging the curtain fabric. In addition, a gap sometimes occurred at the butting ends of both box frames.

The object of the present invention is to solve the above-mentioned drawbacks, and particularly to propose a curtain box frame extension device that can firmly and tightly connect and extend a plurality of box frames using screws and is easy to install.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, symbol A indicates a box frame. This box frame A has vertical side panels 2 and 2 on both sides of the top plate 1, and a curtain rail 1 is placed on the bottom surface of the top plate 1.
0 is formed, and engagement protrusions 11, 11 and screw holes 12 for caps, etc. are formed in the inner middle parts of the side plates 2, 2.
are formed, and furthermore, support edges 13, 13 are formed on the outside of the lower ends of the side plates 2, 2, and engagement grooves 20 are formed in the longitudinal direction on the upper surface of the top plate 1 and the outer surfaces of the side plates 2, 2, respectively. , 30, 30 are formed. Note that 14 is a screw hole for a cap, etc.

Therefore, next we will explain the cases in which box frames are connected and extended in series and the cases in which they are connected and extended at right angles.

First, the box frames A1 and A2 have their end surfaces abutted against each other in series, and are connected via connecting fittings 40, 50 at the top and both sides. This connecting fitting 40 has screw receiving parts 42, 42 on a substantially rectangular base piece 41 with rounded corners, and the width of the base piece 41 is equal to the width of the engaging grooves 30, 30 of the box frames A1, A2. It is set approximately equal to the groove width. When connecting box frames A1 and A2,
Both ends of the connecting fitting 40 are inserted and engaged from the abutting ends into the engaging grooves 30, 30 formed on both sides of the box frames A1, A2, and the screw receiving parts 42, 42...
The screws 45 are screwed in from ... and their tips are pressed against the outer surfaces of the box frames A1 and A2 to fix them. Since the base piece 41 of the connecting fitting 40 itself is formed into a plate shape, it cannot be securely fixed simply by inserting and engaging it into the engaging grooves 30, 30 of the box frames A1, A2. It is firmly fixed with screws 45, 45. Further, the screw receiving parts 42, 42 on both sides of the connecting fitting 40 are connected to each other in the box frame A.
1, A2 are inclined toward the abutting part side, so the screws 45, 45 are also screwed into each other toward the center, and therefore, as shown in FIG. 2, the screws 45, 45 are The tips hit the outer surfaces of the box frames A1, A2 and bite into them, causing the box frames A1, A2
Since the boxes A1 and A2 are pressed in the direction of the arrow, they are tightly engaged in the engaging grooves 30, 30, and at the same time, these boxes A1 and A2 are more closely brought into contact with each other. Therefore, the integration of both box frames A and A becomes more reliable.

Note that the inclined screw receiving portion 4 of the connecting fitting 40
2 and 42 can be easily formed by cutting, bending, cutting, cutting, etc.

The box frames A1 and A2 are also connected at their upper portions via a connecting fitting 50. This connecting fitting 50 has the same configuration as the control connecting fitting 40 except that it is wide and has a large number of screw receiving parts 52. Similarly to the above example, both ends of the base piece 51 are connected to the box frame A.
1, the screw 4 inserted into and engaged with the engagement grooves 20, 20 of A2, and further screwed through the screw receiving portions 52, 52;
5,45.

Next, the end surfaces of the box frames A2 and A3 are cut diagonally and bent to butt each other, and are connected to the inside and outside corners of the top and side surfaces via connecting fittings 60, 70. First, box frames A2 and A3
The inner corner portions of the two are connected via a connecting fitting 60. As shown in FIG. 3, the connecting fitting 60 has a base piece 61,
62 into a right angle, and insert the screw receiving part 6 inside it.
3, 63, and the base pieces 61, 62
The width is the engagement groove 3 on the side of box frames A2 and A3.
It is formed approximately equal to 0.30. When connecting and extending the box frames A2 and A3 at right angles through the connecting fitting 60, the connecting fitting 60
The base pieces 61 and 62 are inserted and engaged into the engagement grooves 30 and 30 from the abutting ends of the box frames A2 and A3, respectively, and the screws 45 and 45 are further screwed into the screw receivers 62 and 62 to firmly tighten them. Fix securely. In this case as well, since the screw receivers 62, 62 are formed in an inclined shape toward the abutting portions of the box frames A1, A2, when screwing the screws 45, 45, these screws 45, 45 are attached to the screw receivers. It advances along the sections 62, 62, bites into the side surfaces of the box frames A2, A3, and presses the box frames A2, A3 in the direction of the arrow. Since the box frames A2 and A3 are bent at a predetermined angle, the box frames A2 and A3 are held at a predetermined angle. Note that the outer corners of the box frames A2 and A3 opposite to the inner corners are connected with connecting fittings (not shown) bent at right angles, as in the case of the inner corners.
A screw receiving part is formed on the outside of the screw, and screws are attached from the outside in the same manner as described above.

Next, the upper parts of box frames A2 and A3 are connected via a connecting fitting 70 shown in FIG. 4. This connecting fitting 70 has base pieces 71 and 72 bent at right angles in a plane, and an inclined screw receiving part 7.
3, 73..., and the base pieces 71 and 72 are inserted into and engaged with the upper engagement grooves 20, 20 of the box frames A2 and A3 from their abutting ends, similar to the above-mentioned connecting fitting 50. and further screws 45, 45...
The box frames A2 and A3 are firmly and tightly fixed by being screwed into the screw receiving portions 73, 73, .

Further, a ceiling plate 85 is supported on one lower end protruding edge 13 of the box frame A having the above structure, and one end portion of a picture frame 86 is supported on the other protruding edge 13. The other end 87 of this frame 86 is fixed to the wall body W. 88 is Satsushi.

As described above, the box frames A1 and A2 and the box frames A2 and A3 are arranged in series and at right angles butt against each other, and the abutting portions are connected by connecting fittings 50 and 70 at the top and by connecting fittings at both sides, respectively. 40 and 60 are firmly and tightly connected and extended by connecting fittings (not shown), so that the integrity of the box frame as a whole is reliably maintained.

Note that the box frame A having the above structure can also be used as a curtain box frame by using the curtain rail 10. Moreover, if the holder 81 is fixedly fixed to the upper part of the blind box 80 in advance, and this holder 81 is pushed up from below the opening of the box frame A and engaged with the engaging protrusions 11, 11, the blind can be used. It can be used as a box frame.

Furthermore, the box frame is not limited to the above frame configuration. For example, the above-mentioned top plate and side plate may be formed as separate structures, and may have a joint frame structure in which they are connected to each other by screwing, fastening, or the like. others,
The configuration of the opening of the box frame is not limited to the downward U-shape as in the above example, but may also be an inverted L-shape. In this regard, the mounting portions of the connecting fittings may be determined as appropriate depending on the fitting conditions of the box frame, and are not necessarily limited to those that are attached to the top plate and side plates. It can be attached only to the top or side panels, and can be used in conjunction with other types of extension devices. Furthermore, although the above embodiment is an example in which the connecting metal fittings are attached to the outer surface of the box frame, the connecting fittings may be attached to the inner surface of the box frame.

As explained in detail above, the extension device for box frames of curtains, blinds, etc. according to the present invention is provided by engaging and attaching the connecting fittings to the engagement grooves at the abutting ends of the box frames that are abutted in series or in a bent manner. At the same time, screw receivers are formed at both ends of the connecting fittings and are inclined toward the abutting portions of the box frames, and screws are screwed into the screw receivers in an inclined manner to secure the abutted box frames. Since it is pressed against the inner or outer surface, both box frames can be firmly and tightly connected and extended. Moreover, since such an effect can be obtained only by screwing in screws, construction is easy.
