ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention is related to an improved slide groove fixing device for use of curtains, comprising a single-track slide body, a movable abutting seat, a transversely U-shaped clamping seat, a supporting spiral member, and an adjusting bolt wherein the movable abutting seat is inserted into the interior of the transversely U-shaped fixing clamping seat and then located into position via the supporting spiral member before said U-shaped clamping seat engaged with said movable abutting seat is installed onto said single-track slide body so as to secure directly a curtain sandwiched between the bottom surface of said single-track slide body and a smaller bottom plate of said U-shaped clamping seat. Via the adjusting bolt, said movable abutting seat can be adjusted upwards or downwards at the interior of said U-shaped clamping seat so as to facilitate the attachment of said curtain tightly onto said single-track slide body.
Please refer to
FIG. 1. A
conventional sliding groove fixing device for curtains as shown in FIG. I is mainly made up of a single-track sliding body
10
, a locating seat
20
, a clamping seat
30
wherein the single-track sliding body
10
is defined by an oblong trough
11
at the top surface; the locating seat
20
is indented into a U-shaped plate
21
at the top surface and provided with a fastening wall
22
extending downwards for a proper length at one lateral side, two corresponding indented L-shaped guiding columns
221
disposed at both lateral sides of said fastening wall
22
, two elongated oval slots
222
disposed between said indented L-shaped guiding columns
221
at said fastening wall
22
, and a fastening plate
223
disposed at the lower section said elongated oval slots, bent in a right angle and extending inwards for a proper length with a thread hole
224
disposed at the middle thereon. The clamping seat
30
is an L-shaped device, having a stop plate
31
disposed at the bottom, two corresponding sliding tracks
32
each defined by a flange bent in an arch and extending backwards from the lateral side of the vertical plate of said clamping seat
30
, and a fixing plate
33
bent in a right angle from the vertical plate thereof with a screw hole
34
disposed thereon.
Please refer to
FIGS. 2
,
3
. In assembly, screws are applied, passing through the elongated oval slots
222
of the locating seat
20
to fix said locating seat
20
onto the lateral side of a window frame. The single-track sliding body
10
is then joined to the bottom side of the locating seat
20
with the oblong trough
11
thereof matching to the indented U-shaped plate
21
thereof. A wooden block
40
with a curtain
90
sandwiched therein is applied to be abutted against the bottom surface of said single-track sliding body
10
. The L-shaped clamping seat
30
is then joined to the locating seat
20
with the sliding tracks
32
thereof led through the indented L-shaped guiding columns
221
thereof. Via a screw led through and screwed up the screw hole
34
of the fixing plate
33
thereof and the thread hole
224
of the fastening plate
223
thereof, the clamping seat
30
is securely attached to the locating seat
20
with the wooden block
40
and the curtain
90
sandwiched therein abutted tightly between the stop plate
31
of the clamping seat
30
and the bottom surface of the single-track sliding body
10
as shown in FIG.
3
.
However, there are several drawbacks to this conventional slide groove fixing device for curtains. First, the structure of said locating seat
20
and said L-shaped clamping seat
30
, especially the fastening plate
223
thereof and the fixing plate
33
thereof, is rather complicated, which enhance not only the difficulty of production, but also the time of processing. Second, the curtain
90
is attached to said single-track sliding body
10
and said L-shaped clamping seat
30
via said wooden block
40
. In case of curtains of different thickness, the thickness of said wooden block
40
also has to be adjusted accordingly so as to clamp the curtain
90
securely onto said single-track sliding body
10
. It is not only inconvenient, but also greatly reduce its applicability in practical uses. Third, through the mediation of said wooden block
40
, said curtain
90
is fixed onto the engaged locating seat
20
and clamping seat
30
. The clamping force, however, is easily dispersed by said wooden block
40
, and thus losing its effectiveness in use. Consequently, the curtain may easily come off when pulled.
SUMMARY OF THE PRESENT INVENTION
It is, therefore, the primary object of the present invention to provide an improved slide groove fixing device for use of curtains, comprising a single-track slide body, a movable abutting seat, a transversely U-shaped clamping seat, a supporting spiral member, and an adjusting bolt wherein the movable abutting seat having an inner-thread adjusting hole and the transversely U-shaped clamping seat having a through hole are integrally molded and economically designed in structure so as to boost the efficiency of production and save the time of processing.
It is another object of the present invention to provide an improved slide groove fixing device for use of curtains wherein the curtain is directly abutted against the single-track slide body through the clamping force of said transversely U-shaped clamping seat engaged with said movable abutting seat without the mediation of said wooden block of a conventional device so that curtains of different thickness can be easily and quickly fixed onto said single-track slide body.
It is a third object of the present invention to provide an improved slide groove fixing device wherein said adjusting bolt can securely facilitate the engagement of said movable abutting seat and said transversely U-shaped clamping seat, thus enhancing the clamping force for fixing said curtain directly onto said single-track slide body without the danger of coming off easily.
It is a fourth object of the present invention to provide an improved slide groove fixing device wherein said supporting spiral member is applied to locate said movable abutting seat into position at the interior of said transversely U-shaped clamping seat before the engaged movable abutting seat and U-shaped clamping seat are installed onto said single-track slide body for easy assembly and economy of the time for assembly.
It is a fifth object of the present invention to provide an improved slide groove fixing device wherein said movable abutting seat located into position by said supporting spiral member will not fall from its location so that the users can be prevented from putting said single-track slide body into wrong place when in assembly.
