Description
s A ~ur~larproof And Wind/Rain Resistant Assembled Blind Background of the Invention Conventional vertical type of blind is composed of thin slats which are hung on a hook member mounted on a wheel seat disposed in an upper beam, whereby an adjusting means installed in the upper beam can be used to collect, stretch and orientate the slats.
Such simple structure can only provide sun-shading function while failing to resist wind or rain 30 that it is apt to be swung by the wind to collide the window and the dust and rain will aIl enter the house. Moreover, such collision often cause the damage of the slats and the window. ~herefore, such blind is unsatisfactory to the user.
SummarL of the Invention It is therefore a primary object of this invention to provide a burglarproof and wind/rain-resistant assembled blind which can effectively insolate the wind and rain.
It is a further object of this invention to provide the above a~smebled blind which can be extensively adjusted and can be assembled by the user.
~a ~t..~s According to the above ohjects, the pre~ent invention includes a fixed guide rail two sides of which are respectively disposed with dove-tail rails, and arch support bases formed with corresponding dove-tail lugs.
Ihe support bases are fitted on the fixed guide rail side by side and a bearing is formed on the support base for a lower connector of a slat to inAert therein. A
shaft rod of a connector extends downward to engage wlth a gear meshing with an inner coil rod of the support base, whereby an adjusting rod can be rotated to adjust the angle of the slats, two ends of the support base are formed with an outer step and an inner step the width of which is equal to that of L-shaped flaps disposed on two sides of each slat. Ihe width of the inner and outer steps and the flaps is adjustable to suit various dimensions of different windows.
Ihe pre~ent invention can be best understood through the following descriptlon and accompanying drawings, wherein:

According to the above arrangement, the fixed guide rail 1 and guide beam 7 can be cut by desired length and then the lugs 21, 22 of the support base 2 can be engaged with the rails 11, 12 of the guide rail 1 to be mounted thereon. Also, the support ba~es 2 can be connected wlth one another by inserting the outer step 25 into the inner step 26 of another support base 2 and then extending the arch strips through the I-shaped groove 27 of the support base and then aligning the shaft rod 433 with the in~ert hole 31 of the strip 3 and 6.
~ ~ 5 then extending the same therethrough (as ~hown in Figs.
2 and 3) and extending into the support base 2 to engage with the meshing means 24 and then extending the adjusting rod 5 through the coil rod of the meshing means 24 to engage with sn adjuseing wheel 6. Since the l-shaped rod 432 of the upper connector 43 i9 biased by the spring, it can be first pushed into the slat for reducing the length of the slat and then moved to the corresponding upper support base 2A and aligned wlth the bearing seat 23 thereof and then released, permitting the spring to push the shaft rod 433 into the upper support base 2A and then the guide rail is fixed and the - guide besm ~s mounted therein and ~ecured on the upper and lower sides of the window frame to complete the assembly as shown in Fig.2.

Fig.5 shows another embodim~nt of the escape device, wherein the upper connector 43 is only disposed with an enga8ing hole while the shaft rod 423 is mounted in the upper support base 2A and two restricting steps are formed on the shaft rod 433 for the spring to bias thereagainst. When assembled, the shaft rod 433 is aligned with the engaging hole of the upper connector 43, permitting the ~pring to push the shaft rod 433 thereinto, while the key can be inserted into the support base to be located between two restricting steps so as to move the shaft rod 433, whereby the shaft rod 433 can be moved into the support base (as shown by the movement from phantom lines to solid lines of Fig.5).
Ihus, the slats can be detached for emergency escape.
Fig.8 shows another embodiment of the emergency escape device, wherein an eccentric rod D is disposed in the key hole 2Al of the upper support base 2A. Ihe end of the eccentric rod D is provided with an eccentric wheel Dl which contacts with the shaft rod 433, whereby the inserted key can first rotate the eccentric rod D, making the eccentric wheel Dl bias the shaft rod 433 outside the upper support base 2A, permitting the slats to be detached for emergency escape.
A link means can be disposed in the support base to permit several shaft rods to be moved by one key 90 -~: ~, 2~7~5 .that the slats can be quickly detAched to fasten the emergency e~cape.
