ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a louver and frame body assembly structure in which various kinds of natural solid pictures and patterns are formed on the beams, columns and slats to beautify the appearance of the louver and frame body. The pictures are coated with a transparent layer which endures the pictures. By means of pivot nails, the linking bar is pivotally connected with the lateral sides of the slats so that it is easy and convenient to assemble the components of the louver.
FIG. 1
shows a conventional louver and frame body structure including an upper beam
10
, a lower beam
11
, two lateral columns
12
, several slats
20
, several driven latch hooks
21
, several pivot pins
22
, a linking bar
30
and several driving latch hooks
31
. The upper beam
10
is an elongated slat-like member having a substantially L-shaped cross-section. The recessed section of the upper beam
10
is disposed with a semicircular receiving cavity
101
. The lower beam
11
is an elongated slat-like member having a substantially L-shaped cross-section. The two lateral columns
12
are also slat-shaped and are opposite to each other. The opposite inner sides thereof are formed with several pivot sockets
121
at equal intervals. The middle of each of the left and right sides of the slat
20
is formed with an insertion hole
201
. The driven latch hook
21
is U-shaped. The pivot pin
22
is a two-step cylindrical member. The linking bar
30
is an elongated bar. The driving latch hook
31
is U-shaped.
When assembled, as shown in
FIG. 2
, the small diameter steps of several pivot pins
22
are respectively fixedly fitted into the insertion holes
201
of left and right sides of the slats
20
. Then several driving latch hooks
31
are nailed on the linking bar
30
at equal intervals. Then several driven latch hooks
21
are latched with the driving latch hooks
31
on the linking bar
30
and nailed on the upper sides of the slats
20
. Then the upper beam
10
, lower beam
11
and two lateral columns
12
are assembled to form a rectangular frame body. At the same time, the pivot pins
22
fixed in the insertion holes
201
of the slats
20
are pivotally fitted into the pivot sockets
121
of the lateral columns
12
. Accordingly, by means of moving the linking bar
30
, the slats
20
are driven to pivotally rotate between the lateral columns
12
so as to adjust the light shading effect.
The conventional louver and frame body has some shortcomings as follows:
1. The upper and lower beams
10
,
11
, lateral columns
12
, slats
20
and linking bar
30
are all made of wooden material or other materials with identical properties which are sprayed with paint with monotonous color. After a long period of being sunned, the paint tends to detach and the appearance will be deteriorated. Under such circumstance, re-painting is necessary.
2. The driving latch hooks
31
are nailed on the linking bar
30
and the driven latch books
21
are latched with the driving latch hooks
31
and then nailed on the upper sides of the slats
20
. In addition, the slats
20
must be pivotally connected with the lateral columns
12
via the independent pivot pins
22
. Such assembling procedure is quite troublesome.
3. The linking bar
30
is positioned at the center of the louver. This affects the entire appearance of the louver.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a louver and frame body assembly structure in which the outer peripheries of the frame body and slats are disposed with opaque layers and decorative articles wrapped by transparent layers. The opaque layers can be made of paper material, recovered paper material, wooden sheet, plastic material, unwoven fabric, woven fabric, etc. The decorative articles can be made of dried flowers, decorative papers, etc. Therefore, various kinds of solid pictures and patterns can be achieved to beautify and endure the appearance.
It is a further object of the present invention to provide the above louver and frame body assembly structure in which by means of the pivot nails, the slats are directly pivotally connected with the linking bar. The resilient pivot heads are integrally formed with the slat so that it is easy and convenient to assemble the components.
It is still a further object of the present invention to provide the above louver and frame body assembly structure in which the linking bar is disposed on lateral side of the slats near the lateral column so that the entire appearance and picture of the louver will not be affected.
