Abstract
A decorative simulated thatch unit includes a clamp, flexible decorative cords, and a press strip. The clamp includes a top wall, two side walls confronting each other, and spaced teeth provided longitudinally along at least one of the side walls and distally from the top wall, and extending toward the other one of the side walls. The top wall cooperates with the side walls to define a receiving space. The decorative cords have U bent portions received in the receiving space and clamped by the side walls, and two end portions extending out of the clamp from the U bent portions through gaps among the teeth. The press strip is received in and is straddled by the U bent portions. The press strip presses the U bent portions against the top wall, and is retained in the receiving space by the teeth.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to a decorative simulated thatch unit, more particularly to a decorative simulated thatch unit capable of being produced in a relatively simple manner.




2. Description of the Related Art




Referring to

FIGS. 1 and 2

, a conventional decorative simulated thatch unit


1


is shown to be nailed onto a roof


4


covered with a waterproofing plastic film


5


so as to decorate the roof


4


. The decorative simulated thatch unit


1


includes a clamp


2


and a plurality of decorative cords


3


made of flexible plastic. The clamp


2


includes a top wall


201


, two side walls


202


extending from opposite longitudinal edges of the top wall


201


and confronting each other, and a plurality of confining units


203


provided longitudinally along both of the side walls


202


and distally from the top wall


201


. The confining units


203


are spaced apart equally from each, and the confining units


203


on one of the side walls are staggered relative to the confining units


203


on the other one of the side walls


202


. The top wall


201


cooperates with the side walls


202


and the confining units


203


to define a receiving space


204


. Each of the confining units


203


has a U bent end portion


2031


, which cooperates with the top wall


201


to confine the decorative cords


3


within the receiving space


204


.




The conventional decorative simulated thatch unit


1


suffers from the following shortcomings:




1. Since the confining units


203


should be processed into a U shape before bending the clamp


2


to form the receiving space


204


, the manufacturing process is relatively complicated.




2. When the gap between two adjacent staggered confining units


203


is too large, some of the decorative cords


3


cannot be properly confined by the staggered confining units


203


. On the other hand, when the aforesaid gap is too small, some of the decorative cords


3


may be destroyed by the confining units


203


.




3. Since each of the confining units


203


has a certain width, the decorative cords


3


may be confined unevenly.




SUMMARY OF THE INVENTION




Therefore, the object of the present invention is to provide a decorative simulated thatch unit which can be produced in a relatively simple manner and which is capable of overcoming the aforesaid drawbacks of the prior art.




The decorative simulated thatch unit according to this invention includes a clamp, a plurality of flexible decorative cords, and a press strip. The clamp includes a top wall having two opposite longitudinal edges, two side walls extending from the opposite longitudinal edges respectively and confronting each other, and a plurality of spaced teeth provided longitudinally along at least one of the side walls and distally from the top wall, and extending toward the other one of the side walls. The top wall cooperates with the side walls to define a receiving space. The flexible decorative cords have U bent portions received in the receiving space and clamped by the side walls, and two end portions extending out of the clamp from the U bent portions through gaps among the teeth. The press strip is received in and is straddled by the U bent portions. The press strip presses the U bent portions against the top wall, and is retained in the receiving space by the teeth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 3 and 4

, the decorative simulated thatch unit


100


according to the preferred embodiment of this invention is adapted to be mounted on a roof


200


covered with a waterproofing plastic film


210


. The decorative simulated thatch unit


100


can be fixed onto the roof


200


by any appropriate method, such as by nailing. The decorative simulated thatch unit


100


is shown to include a clamp


10


, a plurality of flexible decorative cords


20


, and a press strip


30


.




The clamp


10


includes a top wall


11


having two opposite longitudinal edges


101


, two side walls


12


extending from the opposite longitudinal edges


101


respectively and confronting each other, and a plurality of spaced teeth


13


provided longitudinally along at least one of the side walls


12


and distally from the top wall


11


, and extending toward the other one of the side walls


12


. In this embodiment, the teeth


13


of the clamp


10


are provided longitudinally on both of the side walls


12


. Moreover, the teeth


13


on one of the side walls


12


are staggered relative to the teeth


13


on the other one of the side walls


12


. The teeth


13


on the side walls


12


are also spaced apart equally from each other. The top wall


11


cooperates with the side walls


12


to define a receiving space


14


.




The flexible decorative cords


20


have U bent portions


201


received in the receiving space


14


and clamped by the side walls


12


, and two end portions


202


extending out of the clamp


10


from the U bent portions


201


through gaps among the teeth


13


. Each of the flexible decorative cords


20


is made of plastic and has an appearance that simulates a strand of thatch.




The press strip


30


is received in and is straddled by the U bent portions


201


. The press strip


30


presses the U bent portions


201


against the top wall


11


, and is retained in the receiving space


14


by the teeth


13


.




Referring to

FIG. 5

, during the manufacture of the decorative simulated thatch unit


100


according to the preferred embodiment of this invention, the clamp


10


is first placed in a forming groove


51


of a mold


50


. The decorative cords


20


are then evenly arranged on the side walls


12


of the clamp


10


, and the press strip


30


is provided longitudinally on the decorative cords


20


. At this time, the press strip


30


can be punched by a puncher


40


so as to force the press strip


30


and the U bent portions


201


of the decorative cords


20


into the receiving space


14


of the clamp


10


and so that the end portions


202


of the decorative cords


20


extend out of the clamp


10


from the U bent portions


201


of the decorative cords


20


through the gaps among the staggered teeth


13


. At the same time, the side walls


12


of the clamp


10


are deformed to move toward each other, and to preliminarily confine the press strip


30


and the U bent portions


201


of the decorative cords


20


within the receiving space


14


of the clamp


10


.




Referring to

FIG. 6

, the simulated thatch unit


100


′ obtained from the processing step shown in

FIG. 5

is then disposed between two pressing molds


60


. The side walls


12


of the clamp


10


are further pressed by the pressing molds


60


so as to further restrict the press strip


30


and the U bent portions


201


of the decorative cords


20


within the receiving space


14


of the clamp


10


, thereby resulting in the decorative simulated thatch unit


100


shown in FIG.


7


.




The following are some of the advantages of the decorative simulated thatch unit according to this invention:




(1) The decorative simulated thatch unit according to this invention can be produced in a relatively simple manner.




(2) The decorative cords


20


can be properly and evenly confined by the teeth


13


of the clamp


10


. The destruction of the decorative cords


20


as commonly encountered in the prior art can also be avoided.




While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
