A predetermined gap for press-fitting the insertion piece 16 is formed.

The end cap 8 is provided with two projections 12 that project in the radial direction of the pipe members 3a and 3b. One of the protrusions 12 is oriented in the opposite direction (upward) to the tongues 9 and 11, and the other protrusion 12 is oriented in the orthogonal direction (close to the wall surface W). These projections 12 are for hooking the slide ring 13 attached to the end portion side of the curtain 20,
Either one is selected and used according to the attitude (vertical or horizontal) to which the bracket 2 is attached.

The bottom cover 15 has the same planar outer shape as that of the holder frame 6 and is formed so as to cover the lower portion of the holder frame 6 in a good appearance. It has a strip-shaped insertion piece 16.
The insertion piece 16 is designed to be inserted between the tongue pieces 9 and 11 of the end cap 8 fitted in the holder frame 6. As a result, in addition to the function of holding the bottom cover 15 itself, the function of holding the connection between the holder frame 6 and the end cap 8 (that is, the bar body 3) irremovably is also achieved.

In order to attach such a curtain bar to the wall surface W, first, the bracket 2 is screwed or double-sided tape or the like at a predetermined position of the wall surface W (positions having a predetermined interval according to the size of the window etc.). Attach by using together. A predetermined number of slide rings 13 are inserted into the bar body 3, and the lengths of the bar body 2 are adjusted so that the end caps 8 at both ends of the bar body 3 correspond to the holder frames 6 of the bracket 2, respectively. Adjustment (pipe material 3a,

It is also possible to freely remove the bar body 3 from the bracket.
4 and 5 show a second embodiment of the bar installation structure according to the present invention. The difference from the first embodiment is that the holder frame 6 of the bracket 2 is formed in an annular shape, and The point is that the end cap 8 of the main body 3 is formed in an elbow shape.

Corresponding to the circular cross sections of the holder frame 6 and the end cap 8, the tongues 9 and 11 of the end cap 8 also have a plane sectional shape along a circle (not shown). Has been formed. It is the same as in the first embodiment that each pipe member 3a, 3b is adjustable in expansion and contraction in the longitudinal direction, and is relatively rotatable about its longitudinal axis.

With such a structure, the engaging / disengaging structure portion of the bracket 2 and the bar body 3 (that is, the fitting portion of the holder frame 6 and the end cap 8) intersects in the longitudinal direction of the bar body 3. Relative swiveling can be performed around the axis (perpendicular to each other in the example). Therefore, one bracket 2 and the other bracket 2 can be attached to different wall surfaces W intersecting with each other.

Although not shown, both pipe members 3
By relatively rotating a and 3b, one bracket 2 can be attached to the wall surface W and the other bracket 2 can be attached to the ceiling. 6 to 8 show a third embodiment of the bar installation structure according to the present invention. In this embodiment, the holding tool 22 is fitted on the outer peripheral portion of the bar body 3 and the holding tool 22 is attached. The engaging / disengaging structure between the bar body 3 and the bracket 2 is configured via the. The bottom cover 15 attached to the lower portion of the bracket 2 is provided with a wedge 23.

The holding tool 22 is provided with an expansion / contraction portion 26, which is a cutting space for expanding / contracting the inner diameter, at one position on the peripheral portion of the laterally-oriented cylindrical body.
A pair of projecting pieces 27 project downward from both sides in parallel. A backlash preventing piece 28 is provided on the outer surface near the root of each of the protruding pieces 27, a serrated blade 29 is formed on the opposing inner surface, and a return hook 30 is formed on the tip portion.
Further, the outer surface of each of the return hooks 30 is a tapered inclined surface 30a.

On the other hand, the bracket 2 is provided with a mounting portion 4, an arm portion 5 projecting from the mounting portion 4, and a holder provided at a projecting end portion of the arm portion 5, as in the first and second embodiments. It has a frame 6 and. However, the opening through the holder frame 6 in the vertical direction serves as the engagement port 34, and when the projecting pieces 27 of the holding tool 22 are brought slightly closer to each other by elastic deformation (actually, the projecting pieces 27 are When pushed into the engagement opening 34, the inclined surface 3 of the return hook 30
0a acts as a cam, and the protruding pieces 27 are automatically squeezed to each other), and the inner diameter is such that they can be fitted.

In the state in which the protruding piece 27 is fitted in the engaging port 34, when the return hook 30 penetrates the holder frame 6, the return hook 30 elastically returns to a certain degree and enters the engaged state. However, at this time, the protruding pieces 27 do not return to the original mutual distance (before being squeezed), and the bar body 3 is tightened from around it.
The holding tool 22 cannot move or rotate along the bar body 3. On the other hand, the backlash prevention piece 28 is adapted to contact the inner peripheral surface of the engagement opening 34.

A wedge tool 23 provided on the bottom cover 15
Comprises two engaging pieces 36 projecting upward. These engaging pieces 36 are arranged so that when the projecting pieces 27 are fitted in the engaging port 34 as described above, they are separated between the projecting pieces 27 and press them against each other. On the outer surface of the engagement piece 36, there is provided a serrated blade 37 capable of meshing with the serrated blade 29 of the projecting piece 27 so that the pressed state of the projecting piece 27 may be loosened or the wedge tool 23 may fall off. To prevent.

Further, the provision of the return hook 30 on the protruding piece 27 is not always necessary, and it may be expected that the outer surface of the protruding piece 27 and the inner peripheral surface of the engagement opening 34 are prevented from coming off due to friction. . In the third embodiment, in a state before the holding tool 22 is fitted to the bracket 2, unlike the case of the first and second embodiments, the holding tool 22 is positioned with respect to the bar body 3. It has a unique effect that it can be arbitrarily and easily changed along the longitudinal direction (also in the first and second embodiments, by forming the end cap 8 into a tubular shape with both ends open, this can be changed to the bar body 3). However, in this case, a separate positioning structure for the end cap 8 is required). Therefore, there is no inconvenience even if the expansion and contraction adjusting structure is not provided as the bar body 3.

The bar ends 40, which also serve as a decoration and a retainer for the holding tool 22, may be fixed to both ends of the bar body 3. In this embodiment as well, the bracket 2 and the holding tool 22 can be swung relative to each other, and the holding tool 22 and the bar body 3 can be turned relative to each other, so that the bracket 2 can be mounted in any posture.

According to the present invention, which has the above-described structure and is capable of connecting the bracket and the bar body by the one-touch engagement structure, the bracket is first fixed to a predetermined position such as a wall surface. After that, the bar main body can be installed simply by pressing the bar main body against these brackets. Therefore, all work can be easily performed by one worker.

If the bar main body is made adjustable in expansion and contraction, it becomes possible to arbitrarily widen or narrow the mutual intervals of the brackets, so that versatility is expanded. If the bar body is configured to be rotatable about its axis, or the bracket and bar body are relatively swingable, the brackets can be mounted in different mounting positions. , This is also useful for expanding versatility.

If a holding tool having a pair of projecting pieces is externally fitted to the bar body, and the holding tool is forcibly fitted into the engaging opening of the bracket while narrowing the expansion / contraction area between the projecting pieces. By reducing the diameter of the holding tool, the bar body can be tightened from around it. Therefore, the holding tool can be positioned and fixed to the bar body, that is, the bracket can be positioned and fixed. This positioning can be changed arbitrarily and easily in the state before the holding tool is fitted to the bracket. This is also useful for expanding versatility.

In addition, such a structure makes the work of installing the bar body easier and more reliable. Pushing the wedges between the protrusions (expansion / reduction areas) fitted in the bracket engagement holes ensures the engagement between the engagement holes and the protrusions, and further tightens the bar body with the holding tool. Therefore, it is possible to prevent the dropout when it is not intended.
