(Summary of the Invention) Therefore, the present invention provides a curtain or the like in which a retractable tubular loft portion is formed of highly rigid, transparent, and clear colorless plastic, and the loft device is visually inconspicuous when installed. This provides a telescopic support rod. This transparent loft device is effectively invisible when inserted into the edge of sheer sheer curtains or lace curtains, creating shadows and shadows even when light enters through a window. do not have. This transparent rod is
If part or all of it is exposed in a visible position, the background, such as a wall or wooden part, can be seen through the transparent rod, so that the rod blends in with the background and is visually less noticeable.

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

The embodiments shown in FIGS. 1 to 4 will be described.

These drawings show an adjustable rod device such as a curtain or valance, which includes a seamless tubular first rod section (15) and a seamless tubular twentieth rod section (15).

) have a cross section of the same shape, and the second rod part (16)
is such that the dimension of one of the external cross sections is that of the first rod portion (
15) is sufficiently smaller than the internal cross-sectional dimension of
It is inserted in the first rod part (15) so that it can expand and contract. According to the invention, the loft part (15), (
16) is made of a rigid, clear, clear, and virtually colorless plastic, so that the mv flexible rod device is visually unobtrusive when installed, and is a clear, clear, and virtually colorless plastic. There are a few rigid thermoplastics that are compositionally available for making tubular extrusions, including polycarbonate, polymethyl methacrylate, and styrene resins. This clear clear plastic is, for example, a rigid transparent thermoplastic such as is used to manufacture transparent window panes. It is desirable that the clear, sharp plastic used to manufacture the rod section have clear, sharp, and virtually colorless properties compared to the material into which the clear clear window glass is fitted. The tubular rod section formed of transparent plastic has a relatively small print on the new orchid or magazine along one side of the rod device, not only one rod section but also an overlapping section of telescoping rod sections. It is sufficiently transparent and sharp that it can be seen clearly through the lens. Polycarbonate resins are currently preferred not only for their transparency but also for their high impact fracture resistance and high yield strength in the temperature range found in normal chambers. A suitable polycarbonate resin is manufactured by 08 Company (GeneralElect).

The tubular rod portions are formed with different cross-sectional shapes.6 In the preferred embodiment shown, the rod portions have generally non-uniform wall thickness, flat front and back walls, and arched top and bottom walls. A horizontally long rectangular cross section is formed by this. However, the rod portion may have a cross-sectional shape having other polygons or multiple sides, and may also have a circular cross-section, and a bead or rib may be provided along the upper edge of the rod portion. , when using caffe rings, it should be taken into account that the rubbing of the rod surface is suppressed.

In the rod device, rod portions (15) and (16) are provided on a supporting surface such as a window frame (18) or a wall (19) at a constant distance from the supporting surface. In the embodiments of FIGS. 1 to 4, the rod portions (15), (16
) is a symbol (25) at one end of each rod part, respectively.
An inwardly laterally extending end or return indicated at (26) is formed. Conventionally, the loft section has the following features:
It is extruded straight and then reshaped by bending one end of said rod section in a forming gou as appropriate to form a laterally extending return section (25), (26) in each loft section. Although some plastics can be bent without applying heat, it is preferable to apply heat to the bend before extrusion to make the bend easier to bend and reduce stress. In order to facilitate bending of the tubular rod, the forming die brings the rear wall of the rod closer toward the front wall of the rod at the bend, as indicated by reference numeral (27) in FIG. The ends of the return portions (25), (26), which are preferably arranged so as to be pressed against each other, are not flat surfaces facing each other, but instead have a tubular cross-sectional shape. , curtain rod mounting brackets (28), (29) are adapted to provide end returns to the support surface. The force-tensioner mounting brackets (28), (29) are made of metal and have a mounting plate adapted to be attached to the supporting surface by screws or nails, and a lateral fitting that enters the tubular end of each return. and a prong (30) extending upwardly through the top opening of each return section. 1 or more intermediate rond brackets (31
) is adapted to support the rod device on the support surface at a predetermined location intermediate the end return. The intermediate bracket (31) may also be made of transparent, substantially colorless plastic and may be molded by casting. The intermediate placket (31) includes a mounting flange (32), a support arm (33) that is integrally provided with the mounting flange (32) and extends forward from the mounting flange (32), and a support arm (33) that extends forward from the mounting flange (32). It includes a U-shaped saddle (34) provided at the front end and having an opening at the top.

Also, to facilitate the insertion of the curtain rod into the edge of the curtain or valance, a gold ring (35) formed of transparent, virtually colorless plastic is provided at the end of the outer loft section (15). It is located in the department.

As best shown in the third cabinet, the golden ring (35) has a step-like passage extending inside, and the first passage part (35)
a) is formed in a size such that the end of the outer rod part fits snugly therein, and the second passage part (35b) has a smaller cross section than the first passage part (35a); It is sized so that it can be slid freely into the socket. A cross shoulder is formed in the middle of the passage parts (35a) and (35b), and a gold ring (35) is formed there.
is arranged and engaged with the end of the outer loft portion.

The outer wall of the gold ring (35) is preferably formed in a tapered shape as shown by the reference numeral (35d) inward in a direction away from the outer loft part, and the edge of the curtain is formed into a rod part. It makes it easy to lead.

Constructed from transparent, clear, virtually colorless plastic, the curtain loft exhibits see-through properties even where the telescoping loft sections overlap, creating no noticeable silhouettes or shadows when light enters the window. When a clear curtain loft is inserted into the edge of a curtain or valance, it cannot be effectively seen through sheer curtains or lace curtains. Furthermore, the loft is
Even when some or all of it is exposed in a visible position,
Since the background, such as walls and wooden parts, is visible through the transparent loft, the loft device blends in with the background and is visually unobtrusive.

Figures 5-9 illustrate variations of the transparent loft device. The loft device shown in FIGS. 5 to 9 has a first

It is arranged. As shown in FIGS. 8 and 6, the portions (25a') and (25b') are formed in a U-shaped cross section that is elastic in the lateral direction, and each portion has the following:
It has an outer bead or rib (30') arranged to engage the inner side of each loft section. As shown in FIGS. 8 and 6, the portion (25a'), (
25b°) is laterally deformed when it is pressed against the ends of the loft and fits snugly therebetween. Additionally, the other portion of the end return section is formed to have a U-shaped cross section with an opening at the bottom, as best illustrated in FIG. is facilitated. As in the previous embodiment, one or more intermediate support brackets (31°) made of transparent plastic material have a mouth interposed between their ends.

It can be provided to support a card device.

In FIG. 1O and FIG. 1), different functions and effects can be produced by utilizing the transparency of the loft portion. As shown in Figures 10 and 1), decorative inserts such as bands, ribbons, etc. (36) are inserted into the transparent tubular rod section (36).
15'), (16'). The decorative insert is visible through the transparent tubular loft and is preferably colored and decorated to provide the rod with a selected decorative appearance or color.

From the foregoing, it is easy to understand that the adjustable transparent rod is made of transparent, clear, and virtually colorless plastic, so that the rod device can be used at the edges of curtains or decorative folds. When inserted into the vehicle, it is virtually impossible to shade the area, and does not create noticeable shadows or silhouettes when light enters from behind. Furthermore, if the rod device is arranged so that part or all of it is exposed in a visible position, the rod device tends to blend in with the background, making it even more visually conspicuous. It disappears. The transparent rod device may also serve to obtain special decorative effects by inserting decorative elements into the transparent tubular rod part.
