Abstract
There is disclosed a venetian blind (50) having a top bar (21), a bottom bar (20) and horizontal slats (35) disposed between the top and bottom bars (21; 20). There is also a raising mechanism (30, 31) for adjusting the height of a bottom bar (20) of the venetian blind (50). The raising mechanism (30, 31) comprises a first member (11,13) attached to the top bar (21) and a second member (10, 12) attached to the bottom bar (20). There is also a cord (1,2), which is attached at one end of the venetian blind (50) and is fed past the first and second members (11, 13; 10 , 12). In such an arrangement the displacement of the free end of the cord (25) is greater than the displacement of the bottom bar (20), to adjust the height of the bottom bar (20) with a mechanical advantage.
Description
Technical field
The present invention relates to a kind of venetian shutter or venetian blinds (venetian blind), particularly relate to a kind of hoisting mechanism of venetian shutter.
Background technology
Venetian shutter (curtain) has push rod and bottom bar.Push rod can be connected window frame top or similar installation portion.Bottom bar then utilizes the stay cord of hoisting mechanism to be suspended on below the push rod.Horizontal blade is suspended between push rod and the bottom bar.By the inclination angle of the horizontal blade that fascinates, can regulate light-inletting quantity through window.If desired, this venetian shutter also can rise, so that light enters window fully.
The many ropes that the operator can spur a rope or set bunchy promote shutter.This operation promotes the bottom bar of shutter by restricting towards the push rod pulling towards push rod.Along with bottom bar contacts each blade, horizontal blade gathers on the bottom bar, Open from This Side shutter.
The weight of window blind assembly (being the blade that bottom bar and quilt are assembled) makes that requiring very harsh to operation is a big problem of venetian shutter.This problem is particularly outstanding for wooden shutter, and the weight of this wooden shutter sometimes can be above 10 kilograms.
Therefore, need a kind of system badly, this system can provide the mechanism that is easy to handle venetian shutter to the operator.
Summary of the invention
The invention provides a kind of venetian shutter, it has a push rod, bottom bar, a plurality of horizontal blade between the described top and bottom bar, hoisting mechanism that is used to regulate described shutter bottom bar height of being arranged in, and wherein said hoisting mechanism comprises:
First parts that link to each other with described push rod,
Second parts that link to each other with described bottom bar, and rope, described rope is connected to an end of described venetian shutter, and by the described first and second parts feedings,
Wherein, the free-ended displacement of described rope is greater than the displacement of described bottom bar, to regulate the height of described bottom bar by mechanical advantage.
First and second parts can be any elements, and this element can make rope pass through under the situation that does not have excessive frictional resistance.
Preferably, rope links to each other with the push rod of window blind assembly.More preferably, rope is connected near first parts that are connected on the push rod.
Randomly, first parts can be one of a plurality of likes that link to each other with push rod, and the parts feeding of rope by linking to each other with push rod.In a further possibility, second parts can be one of likes that links to each other of a plurality of and bottom bar, and rope by with the parts feeding that links to each other of bottom bar.
Preferably, described parts are revolving part.Like this, described parts can along with rope pass through rotate.Particularly preferably, described parts are pulley.
Preferably, venetian shutter is provided with at least two hoisting mechanisms.
Preferably, venetian shutter also has the other parts of the rope that is used to receive hoisting mechanism.
Preferably, described other parts are revolving parts.Like this, described other parts will rotate along with the motion of the rope that passes through.Particularly preferably, described other parts are pulleys.
Description of drawings
For more clearly showing the present invention, below with reference to accompanying drawing and only by way of example mode one embodiment is illustrated, in the accompanying drawings:
Fig. 1 is the front schematic view of venetian shutter of the prior art;
Fig. 2 is the front schematic view of venetian shutter according to an embodiment of the invention, and wherein this shutter drops to extreme lower position;
Fig. 3 is the state that the venetian shutter of Fig. 2 is partly promoted;
Fig. 4 is the schematic axonometric projection graph of venetian shutter in accordance with another embodiment of the present invention, and wherein this shutter drops to extreme lower position.
The specific embodiment
Fig. 1 demonstrates a traditional venetian shutter assembly 150, and described assembly 150 has a push rod 121, bottom bar 120, a plurality of horizontal blade 135, a blade is assembled rope 125 and hoisting mechanism 130,131.The stay cord 160,161 that hoisting mechanism 130,131 comprises pulley 111,113 and is connected with bottom bar 120.Stay cord 160,161 is all by secondary pulley 115, and the formation blade is assembled rope 125.In the hoisting mechanism 130,131 of this window blind assembly 150, the displacement of blade gathering rope 125 converts the equivalent displacement of bottom bar 120 to.
Fig. 2 shows that a bottom bar 20 is in the window blind assembly 50 of lower position.The push rod 21 of this window blind assembly 50 can be fixed in the top of a window (not shown).Horizontal blade 35 is arranged between bottom bar 20 and the push rod 21.Assemble the position that the length of rope 25 can change bottom bar 20 by changing blade, can adjust window blind assembly 50 thus.
Fig. 3 demonstrates the window blind assembly 50 among the Fig. 2 that is in the part enable possition, and wherein bottom bar 20 is between extreme higher position and extreme lower position.Along with bottom bar 20 is raised, horizontal blade 35 is gathered on the bottom bar 20.Thus, horizontal blade 35 is raised by bottom bar 20.
Blade is assembled rope 25 and is made of stay cord 1 and 2, and stay cord 1,2 is connected with hoisting mechanism 30,31 respectively.Stay cord 1,2 is connected with push rod 21 at tie point 5,6 places respectively.Tie point 5,6 is positioned near the elementary pulley 11,13 in corresponding top.From tie point 5, stay cord 1 is at first around by being fixed in the elementary pulley 10 in bottom on the bottom bar 20, then by being fixed in the elementary pulley 11 in top on the push rod 21.
Similarly, from tie point 6, stay cord 2 is at first around by being fixed in the elementary pulley 12 in bottom on the bottom bar 20, then around by being fixed in the elementary pulley 13 in top on the push rod 21.Stay cord 1,2 is then around by secondary pulley 15, and forms blade at this some place and assemble rope 25.
Between the elementary pulley 10,12 of tie point 5,6 and bottom and between the elementary pulley 11,13 of elementary pulley 10,12 in bottom and top, stay cord 1,2 has the orientation of perpendicular.Like this, bottom bar 20 from tie point 5,6 and top elementary pulley 11,13 suspended.
Gathering blade that is draped and bottom bar 20 are by four hitch points (the elementary pulley 11,13 in tie point 5,6 and top) load-bearing.Stay cord 1,2 will put on the weight transfer of the hanger on the elementary pulley 11,13 in each top to secondary pulley 15, and finally pass to gathering rope 25.Because the gravity of hanger evenly distributes, for the shutter fix in position, assemble needed power on the rope 25 and be half of hanger gravity between hitch point.Assemble the displacement of the displacement of rope 25 greater than bottom bar 20.Just can obtain mechanical advantage when like this, promoting bottom bar 20.
Fig. 4 shows the window blind assembly 50 with two hoisting mechanisms.Push rod 21 has the elementary pulley 11,13 in top, and provides tie point 5,6 for stay cord 1,2 simultaneously.Secondary pulley 15 is connected near the end of push rod 21, assembles rope 25 so that the operator can handle away from hoisting mechanism.
Person skilled in the art person can realize multiple remodeling within the scope of the invention at an easy rate.Therefore, the present invention is not limited to above-mentioned illustrational specific embodiment.
