However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosure form, and it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

The dual semi-automatic blind according to the present invention includes a blind housing 100 and a blind screen 200, as illustrated in FIG. 1.

At this time, the blind housing 100 may have various appearance shapes.

However, the inside of the blind housing 100 is empty, and a slit (not shown) of a certain width is formed in the lower portion so that a plurality of driving strings can pass therethrough.

In addition, the blind housing 100 is fixed to a wall or a wall or a frame on which a window is installed through a blind fixing member 300.

At this time, the blind fixing member 300 may also have various shapes including a known bolt fastening type, and the blind fixing member 300 specialized in the present invention will be described later.

In addition, the inside of the blind housing 100 is rotated from one end to the other end 110, the first upper adjustment member 120, the first lower adjustment member 130, and the second upper adjustment member 140 ), The second lower adjustment member 150 and the lower adjustment stopper 160 are sequentially fixed at intervals.

On the other hand, the blind screen 200 is made of a folding fabric 230 that can be folded while connecting the upper frame 210 and the lower frame 220 and the upper frame 210 and the lower frame 220.

Here, the foldable fabric 230 may be a plurality of blades, and may have a form that can be folded as illustrated in FIG. 6.

That is, it may be folded in the same form as the example of FIG. 6, and of course, it may be folded in other forms.

In addition, the rotary shaft 110 has the same structure as that used to normally open and close the vertical, the cylindrical rotary body 110 fixed to the inside of the blind housing 100, and the rotary body ( The rotor 114 is inserted into one end of the 112 and assembled to be rotated in place, and a ball-shaped adjustment line 116 for determining the rotation direction of the rotor 114 according to the direction of being wound around the rotor 114 Includes.

Therefore, the ball-shaped control line 116 is spaced apart by the diameter of the rotor 114, both ends are connected to each other to form a ring.

Therefore, when pulling the front of the ball-shaped control line 116, the rotor 114 rotates clockwise, and when pulling the back, the rotor 114 rotates counterclockwise.

And, inside the blind housing 100, a pair of first and second shafts S1 and S2 are arranged parallel to each other, and these first and second shafts S1 and S2 are square bars having a rectangular cross section. Form.

Among them, one end of the first shaft (S1) enters the inside through the other end of the rotary body 112, and then is inserted and fixed to the rotor 114 so that the rotor 114 rotates It is configured to rotate together.

At this time, the other end of the first shaft S1 is maintained in a free end state without being fixed.

In addition, one end of the second shaft (S2) is fitted and fixed to the lower adjustment stopper 160, the other end is arranged in the opposite direction, it is also maintained in a free end state without being constrained.

That is, in the first and second shafts S1 and S2, opposite ends of each other are respectively constrained, and opposite ends of each other are maintained in a free end state.

In addition, the first upper adjustment member 120 and the second upper adjustment member 140 is made of the same structure, the first lower adjustment member 130 and the second lower adjustment member 150 are each of the same structure Is done.

Therefore, the following description only illustratively describes the first upper adjustment member 120 and the first lower adjustment member 130.

According to Figure 2, the first upper adjustment member 120 is a pair of plates are connected by a plurality of ribs of the upper adjustment member body 122 having an externally rectangular shape, and the upper adjustment member body 122 An empty through hole (PAS) formed through the plate surface, a drum axis hole (DRH) formed at a distance from the empty hole (PAS), and an upper adjustment member drum (124) rotatably fixed to the drum axis hole (DRH) And, it is wound around the upper adjustment member drum 124 and the end includes an upper adjustment line 126 fixed to the upper frame 210 of the blind screen 200.

At this time, the first shaft (S1) is assembled to be mutually engaged through the shaft of the upper adjustment member drum (124), the drum shaft hole (DRH) is formed by including the upper and lower control lines.

That is, a hole corresponding to the square shape of the first shaft S1 is formed on the shaft of the upper adjustment member drum 124, so that when the first shaft S1 is fitted, it is engaged with each other due to the angled portion (square). In the rotational direction of the first shaft S1, the upper adjustment member drum 124 is also rotated.

And, the second shaft (S2) is arranged to pass through the empty hole (PAS), the empty hole (PAS) is configured to rotate the second shaft (S2).

In other words, the upper adjustment member drum 124 is provided only on one side of the lower adjustment member body 132 so as to be combined only with the first shaft S1, and the second shaft S2 passes through and is configured to idle.

In addition, although the first lower adjustment member 130 is structurally similar to the first upper adjustment member 120 described above, the positions of the empty hole PAS and the drum shaft hole DRH are interchanged.

For example, the first lower adjustment member 130 also has a pair of plates connected by a plurality of ribs to form a lower control member body 132 having a rectangular shape and a plate surface of the lower adjustment member body 132. A through-hole formed through the hole (PAS), a drum-shaft hole (DRH) formed at a distance from the through-hole (PAS), and a lower adjustment member drum (134) rotatably fixed to the drum hole (DRH), The lower adjustment member drum 134 is wound around the circumference and an end includes a lower adjustment line 136 fixed to the lower frame 220 of the blind screen 200.

At this time, the second shaft (S2) is assembled to be mutually engaged through the axis of the lower adjustment member drum (134).

That is, the drum of the lower adjustment member drum 134 is formed with a drum shaft hole (DRH) that fits the square shape of the second shaft (S2), so that when the second shaft (S2) is fitted, an angled part (square) Therefore, the lower adjustment member drum 134 is also rotated in the rotational direction of the second shaft S2 by being engaged with each other.

And, the first shaft (S1) is arranged to pass through the empty hole (PAS), the empty hole (PAS) is configured to rotate the first shaft (S1).

In other words, the lower adjustment member drum 134 is provided only on one side of the lower adjustment member body 132 so as to be combined only with the second shaft S2, and the first shaft S1 passes through the empty through hole PAS. It is constructed in vain.

At this time, the second upper adjustment member 140 and the second lower adjustment of the same structure as the first upper adjustment member 120 and the first lower adjustment member 130 for smooth operation while maintaining the balance of the blind screen 200 The member 150 is further provided.

Accordingly, as in the use examples of FIGS. 4 and 5, when the ball 110 is rotated clockwise by pulling the ball control line 116, only the first shaft S1 is constrained to the ball 110 Therefore, only the first shaft S1 is rotated clockwise to release the upper control line 126.

Then, the blind screen 200 descends due to the weight of the blind screen 200. At this time, the lower frame 220 does not move, but only the upper frame 210 is lowered in a fixed position. When the other side of 116 is pulled, the field of view can be secured, and on the contrary, the occluded position that can be covered by the user can be adjusted.

The same is true in the opposite case, but when the rotating sphere 110 is rotated counterclockwise, only the upper frame 210 is raised.

That is, it is the upper frame 210 that is moved by the manipulation of the ball-shaped control line 116, and at this time, the lower frame 220 continues to maintain a fixed position.

Therefore, only the upper frame 210 is moved in a state where the lower frame 220 is disposed in an appropriate position, so that only the occluded position desired by the user can be covered.

On the other hand, the lower adjustment stopper 160, which will be described later, includes a spiral spring of a plate shape, but the position is always fixed by a spring of a special shape, so that the user holds the lower frame 220 by hand and pushes it up or down. When it moves smoothly, it stays fixed in the raised or pulled position.

Therefore, the user can determine the occlusion width by adjusting the upper frame 210 in a state where the lower frame 220 is raised or lowered to a desired occlusion position.

Because of this structure, the blind according to the present invention is a dual structure in which the upper frame 210 and the lower frame 220 are moved separately, and since the position of the lower frame 220 is semi-automatic, the dual semi-automatic blinds are effectively used. Will be implemented.

Then, the lower adjustment stopper 160 will be described in detail.

The lower adjustment stopper 160 includes a first case 1610, a second case 1620 assembled to the first case 1610 to make space therein, and the first and second cases, as illustrated in FIG. 3. Spring winding drum 1630 rotatably assembled inside the cases 1610, 1620, and a plate-shaped spiral spring 1640 installed in parallel with the spring winding drum 1630 and wound around the spring winding drum 1630 Includes.

At this time, a large diameter coil storage portion 1612 is formed in a cylindrical shape inside the first case 1610, and a spring boss 1614 protrudes to an adjacent side of the large diameter coil storage portion 1612.

In addition, a square second shaft assembly hole 1622 is formed through the second case 1620 in a straight line with the center of the circle of the large diameter coil storage part 1612, and the straight position with the spring boss 1614. In the spring shaft hole 1624 is formed through.

In addition, at the center of one side of the spring take-up drum 1630, the second shaft assembly hole 1622 and a second square shaft assembly groove 1634 in a straight line are formed in a certain depth, and a part of the drum surface which is a circumferential surface. Is cut through the diameter of the spring fitting slits (1634) is formed, a spring fixing groove (1636) is formed on the spring fitting slits (1634), the other side of the spring winding drum (1630) protruding a certain length The small cylindrical coil pressing portion 1638 is formed to protrude in the form of a projection.

In addition, a spring fixing hole 1642 is formed at one end of the plate-shaped spiral spring 1640.

In addition, inside the first and second cases 1610 and 1620, a small diameter coil 1650 and a large diameter coil 1660 are integrally formed.

Thus, the small diameter coil 1650 is inserted into the small diameter coil crimping unit 1638, one end is fixed to the small diameter coil crimping unit 1638, and the large diameter coil 1660 is inserted into the large diameter coil storage unit 1612. After the end is fixed to the large diameter coil storage unit 1612, in this state, the end of the second shaft (S2) in the second shaft assembly groove (1632) penetrates through the second shaft assembly hole (1622) and is fixed, The shaft portion SF protruding from the center of the side cross-section of the small diameter coil compression portion 1638 is axially fixed rotatably while being inserted into the large diameter coil storage portion 1612.

Therefore, when the second shaft S2 is rotated, the spring take-up drum 1630 can rotate in place.

In addition, the plate-shaped spiral spring 1640 is fixed to a spring boss 1614 after a spring shaft (not shown), not shown, penetrates through the centers of the spring shaft hole 1624 and the plate-shaped spiral spring 1640, Since the spiral spring 1640 is axially fixed in a state fitted to the spring boss 1614, this also becomes a rotatable state.

At this time, the wound inner end of the plate-shaped spiral spring 1640 is fixed to the spring boss 1614, and the outer end where the spring fixing hole 1642 is formed is wound about half a turn on the drum surface of the spring winding drum 1630. After bending, it is fitted into the spring fitting slit 1634, and then a separate fixing member is fixed to the spring fixing hole 1642 in the spring fixing groove 1636.

Due to this structure, the spring winding drum 1630 always tries to rotate in the direction in which the plate-shaped spiral spring 1640 is wound.

For example, when the user holds the lower frame 220 and pulls down the blind screen 200, the lower control line 136 is pulled, so that the second shaft S2 rotates clockwise.

Then, the end of the second shaft (S2) rotates the spring take-up drum 1630 clockwise, and accordingly the plate-shaped spiral spring 1640 is wound around the drum surface of the spring take-up drum 1630, thereby returning to the elasticity. Will accumulate.

However, the small-diameter coil 1650 and the large-diameter coil 1660 are designed to be released when rotating clockwise, that is, to increase the coil diameter, and to be reduced when rotating counterclockwise.

Therefore, when the spring take-up drum 1630 rotates in the clockwise direction, the small-diameter coil 1650 inserted into the small-diameter coil crimping portion 1638 becomes larger and becomes looser with respect to the small-diameter coil crimping portion 1638, but the large-diameter coil 1660 ) Becomes larger as the coil diameter becomes larger and fills the inside of the large diameter coil storage unit 1612, thereby preventing rotation of the spring winding drum 1630.

At this time, basically, even if the coil diameter of the large diameter coil 1660 increases, it should be designed to be smaller than the original coil diameter of the large diameter coil 1660, that is, when the coil is not subjected to a force. Otherwise, if the coil diameter becomes large and it is full and fixed to the large diameter coil storage unit 1612, when the force pulled is removed, the fixed state is released because of the property of returning to the original coil diameter. Accordingly, the coil diameter of the large diameter coil 1660 should be reduced and inserted during initial assembly.

Then, when the large diameter coil 1660 is rotated as far as possible in the clockwise direction, that is, when the lower frame 220 is lowered to the maximum, the original coil diameter may be kept to maintain the state of being uncoiled.

As a result, when the lower frame 220 is pulled down to an arbitrary position, even when the coil diameter of the large diameter coil 1660 becomes full and the user pulls the full diameter of the large diameter coil storage unit 1612, the pressure force of the large diameter coil 1660 is a plate-shaped spiral The plate-shaped spiral spring 1640 is larger than the elastic return force of the spring 1640, and is not elastically restored, but maintains the withdrawn state.

Conversely, when the user slightly pushes up the lower frame 220, the balance of force is broken and the elastic return force of the plate-shaped spiral spring 1640 becomes larger, so that the spring take-up drum 1630 rotates counterclockwise, and its elasticity Lifting of the lower frame 220 is smooth and easy due to the return force.

Then, the small-diameter coil 1650 fitted to the small-diameter coil crimping section 1638 and the end fixed to the small-diameter coil crimping section 1638, the small-diameter coil crimping section becomes smaller and smaller as the coil diameter becomes smaller as it rotates counterclockwise. (1638) is pressed with considerable force.

Therefore, even if the user lifts to a certain point and releases the pushed-up, the pressing force of the small-diameter coil 1650 is greater than that of the plate-shaped spiral spring 1640, and the plate-shaped spiral spring 1640 cannot be elastically restored. It will remain intact.

As such, the lower adjustment stopper 160 guides the user to easily adjust the position of the lower frame 220.

On the other hand, as illustrated in FIG. 7, the blind fixing member 300 constituting the dual semi-automatic blind according to the present invention is fastened to both ends of the blind housing 100, and a fixing bolt 310 capable of adjusting length is fixed. It is integrally fixed to the end of the bolt 310 and includes a contact knob 320 that is in close contact with the wall.

Thus, without having a separate anchor bolt or fixing bracket, the blind housing 100 is leveled and rotated so that the contact knob 320 is brought into close contact with the wall to make the blind housing very easy and quick. ).

At this time, in order to increase the fixing force, an expansion and contraction plate 330 may be further provided on the outer surface of the contact knob 320.

In this case, the expansion and contraction plate 330 is made of rubber, silicone, etc., and has elasticity, thereby increasing adhesion, thereby increasing fixing stability.

In addition, the concave-convex portion 340 may be further formed on the outer surface of the contact knob 320 so as not to flow easily in the jammed state.

On the other hand, as shown in the example of Figure 8, the lower frame 220, the fabric bar fixing groove 222 for fixing the fabric 230, the auxiliary fabric at the bottom of the lower frame 220, the insertion groove of the secondary bar 224 To further form, by installing the auxiliary fabric 228 by allowing the auxiliary fabric bar 226 to be inserted into the auxiliary fabric bar insertion groove 224, a separate auxiliary fabric 228 in the form shown in FIG. After installation, it can be configured to tie the center with a string (STR) to see more of the bow-shaped folding interior effect.

That is, such a structure is also described in FIG. 6, so that the auxiliary fabric 228 can be further installed detachably, so that various blinds can be implemented according to a user's preference.

This example may be suitable, for example, in a T / T (TILT & TURN) window. That is, in the case of the T / T window, the upper side may be a window that can be opened based on the mullion, and the lower side may be a fixed window that cannot be opened. At this time, the basic type blinds of the present invention are installed only to the upper side of the mullion, and the fixed window The part is intended to be installed and used in the form of FIG. 9 according to the user's selection.

Of course, it is not necessarily limited to the T / T window, and the fixed window and the sliding window (or the openable window) may be applied to all the windows that are partitioned up and down by mullions even if the example is an open or openable window.

In addition, in addition to the detachable and detachable assembly type as shown in the example of FIG. 8, it can be realized that the auxiliary fabric bar 226 can be implemented as an integrated structure integrally integrated with the lower frame 220 from the beginning.
