Screen device for building windows {SCREEN DEVICE FOR WINDOW IN BUILDING}

(Technology)

The present invention relates to a screen device for building windows, and more particularly to a screen device for building windows that can be mounted on the windows of various buildings to effectively block the gaze from the outside while maintaining a certain amount of light.

(Background)

It is common to make windows in apartments, townhouses, detached houses, villas, offices, etc. in order to enjoy the advantages of natural light. However, these windows are preferable facilities in that sunlight can be guided into the room and secure a view outside the window, but there is a problem in that privacy can be inadvertently invaded due to being vulnerable to the eyes from the outside. For this reason, most windows have various screen means such as curtains and blinds, or opaque or semi-transparent sheets are set up to block outside eyes.

Such conventional screen means have the advantage of achieving the desired purpose of protecting the privacy by blocking the external body, but has an inevitable disadvantage in its use.

That is, the conventional screen means, once hitting the window for the purpose of blocking the external gaze, not only blocks all the sunlight until walking, but also completely blocks the gaze (view) out of the window, so that the unique function of the window, such as skylight and eye catching There is a problem that you lose.

For example, a conventional conventional curtain having a structure of covering and closing the top and bottom of a window and opening and closing it to the left and right is left open for up to a part of the sky. It is impossible to block the gaze at all, so if you want to cover the outside gaze in reality, it is necessary to close the entire curtain. This problem also applies to vertical blinds called verticals.

In addition, the general conventional blinds, which cover the entire left and right sides of the window and bend down from the top, when the part is left open for partial light, the lower part of the entire window is opened, as shown in FIG. Since all are exposed to the blocking of the external gaze, the entire blind 100 must be closed.

On the other hand, sheet selection includes the inherent problem of sunting, which is inevitably in a state of being kept until it is removed once the sun is removed.

The object of the present invention is to solve the problem of inconsistency between the blocking of the gaze and the light from the outside of the conventional window device for a window as described above can effectively block the gaze from the outside while maintaining a certain degree of light and view. It is to provide a screen device for a building window.

As shown in FIG. 1, the screen device 1 for a building window according to the present invention includes a housing 10, a screen 20, and a pair of rope winding mechanisms 30.

As shown in FIG. 1, the housing 10 is fixed to a lower side of the window 2 (for example, a lower window frame) by a fastening mechanism such as a screw, so that the screen 20 can be elastically stored and drawn out. The main body of the present invention screen device (1). The housing 10 is provided with a structure in which the screen 20 is elastically wound so that the screen 20 can be pulled out by forcibly pulling it up.

As illustrated in FIG. 2, the housing 10 includes a rotating roller 11 in which the screen 20 is unwinded, a shaft 12 rotatably supporting the rotating roller 11, and the rotating roller. (11) and the shaft 12 is coupled by a spring fixing body (13A) so that the screen 20 is released from the rotary roller (11) accumulates elasticity and the screen 20 is rotated by the accumulated elastic roller ( It may be configured to include a spring (13) for applying a force to be wound on 11).

It is preferable to form fasteners 15 on both sides of the cover 10 of the housing 10 so as to fasten screws for fixing the housing 10 to the frame of the window 2 or the wall under the window.

The screen 20 elastically wound on the rotary roller 11 is a member that is unfolded on the window 2 so that the indoor can not be seen from the outside. Therefore, as the screen 20 used in the present invention, it is possible to use various cloths or plastic sheets, etc., having flexibility enough to be easily wound and unwound on the rotary roller 11 while having an opacity of not being able to see the indoors outdoors. .

Preferably, the lower end of the screen 20 is fixed to the rotary roller 11 by a fixture 21 such as a chord, the upper end of the screen 20 to maintain the parallel to the screen 20 of the upper frame 22 Is coupled, the upper frame 22 is equipped with a handle 23 for folding and unfolding the screen 20.

Rope winding mechanisms 30 are respectively installed at positions (eg, intermediate positions of the entire height of the window) spaced apart from the housing 10 at positions corresponding to both ends of the screen 20.

The rope winding mechanism 30 is provided with a rope 31 wound by elasticity and one free end 31A of which is bound to the screen 20 (preferably the upper frame), and from the housing 10 to the screen 20. It acts to exert a force to withdraw.

That is, due to the functional characteristics of the housing 10 described above, the screen 20 is forced to be wound on the rotating roller 11 by the action of the spring 13, so that the screen 20 is pulled out and the hand is released. 20 is wound into the housing 10 again. Therefore, in order to block the winding of the screen 20, a fixed structure for fixing the screen 20 in the drawn state is needed. In the screen device 1 of the present invention, the winding of the screen is blocked by the rope winding mechanism 30 )

The rope winding mechanism 30 is rotatably mounted with respect to the rotating shaft 33 to wind the rope 31 and the rope 31 bound to the screen 20, for example, as shown in FIG. A winding drum 32, a winding spring 34 that exerts an elastic force toward the winding drum 32, a friction plate 35 that applies friction to the winding drum 32, and It may be configured to include a control nut 36 (butter nut) is fastened to the rotary shaft 33 to adjust the frictional force of the friction plate 35 applied to the winding drum (32). At this time, the spring 13 and the winding spring 34 embedded in the housing 10 are selected so that the strength of the elastic force is balanced to each other in unfolding and walking the screen 20.

Therefore, when the screen 20 is raised (unfolded), the spring 13 of the housing 10 requires a predetermined force as the elastic force accumulates, but the winding spring 34 provides a force to be pulled upward. It is possible to unfold the screen 20 with a small force. On the contrary, when the screen 20 is lowered (when walking), a predetermined force is required as the elasticity is accumulated in the winding spring 34, but the spring 13 is lowered. By providing a pulling force to the zoom it is also possible to walk the screen 20 with less force.

Depending on the unfolded position of the screen 20 (extreme fully unfolded and fully walked), the cumulative elastic forces of the two springs 13, 34 are out of balance and are forced into the unfolded or unrolled screen 20. For example, when fully unfolded, the elastic force accumulated in the spring 13 is greater than the elastic force accumulated in the winding spring 34 so that the screen 20 is forced to the side to be rolled up (the descending side).

However, the screen device 1 of the present invention, even if the elastic force of the two springs (13, 34) is out of balance, the screen by the frictional resistance of the housing 10, the screen 20 and the rope winding mechanism 30, etc. (20) is not unintentionally unfolded or lifted. That is, according to the screen device 1 of the present invention, the screen 20 is not unintentionally unfolded or rolled up even when the screen 20 is unfolded in any state between the fully unfolded state and the fully unrolled state. In addition, the elastic force balance of the spring 13 and the winding spring 34 can be adjusted more appropriately by adjusting the elastic force of the winding spring 34 by the adjustment of the adjustment nut 36.

The rope winding mechanism 30 can be fixed to the window frame of the window 2 or the guide 40 described later by using the support 38 formed on the casing 37. In the illustrated embodiment, an example in which the support 38 is formed only on the lower side of the casing 37 is shown. However, the guide 38 is not used by forming the support 38 on the upper side of the casing 37. When the top and bottom can be securely fixed to the window (2). 38A shows a threaded hole formed in the support 38.

As mentioned above, it is preferable to provide a guide 40 between each side of the housing 10 and the respective rope winding mechanisms 30, respectively. Each guide 40 may be formed in a substantially depressed shape (?? type) with one side open so that one end of the screen 20 is inserted in, and the two guides 40 are the screen device 1 of the present invention. On both sides of the window (2) to be installed is installed so that the opening of the recess (? Type) facing each other.

The lower end of each guide 40 is connected to both ends of the housing 10, and the upper end thereof extends to a predetermined height of the window 2 (e.g., to about the middle of the entire height of the window) to be stored and drawn out of the housing 10. To guide the screen 20 naturally. In addition, the rope 31 of the rope winding mechanism 30 is moved up and down in the state located in the guide 40 so that the rope 31 is not exposed to the outside. Reference numeral 41, which is not described, denotes a fastener for fixing the guide 40 to the window frame.

As described above, when the screen device 1 of the present invention has a characteristic structure that is mounted below the window 2 and lifts the screen 20 upward to partially shield only the bottom of the window 2. As shown in FIG. 5, sunlight is emitted from the upper part of the window 2 where the screen 20 is not extended to maintain indoor light, and the outdoor part can be viewed through the upper part. The lower part of) is shielded by the screen 20 to effectively block the eyes of outsiders.

According to the screen device for a building window (1) according to the present invention, the problem of incompatibility between the blocking and light from the outside of the existing building window screen device has been solved, thereby keeping the view from the outside while maintaining the lighting and the external view. There is an effect that can effectively block the.

In addition, due to the interaction of the spring 13 of the housing 10 and the winding spring 34 of the rope winding mechanism 30, the screen 20 can be easily unfolded and walked with little force, and the unfolded screen 20 can be opened. Even without a separate fixing device for fixing, the screen 20 can be positioned in any state between a fully unfolded state and a fully rolled state, which is very convenient to use.

In addition, when the screen device 1 of the present invention is used together with other screen devices such as curtains and verticals, it is possible to more efficiently solve the light and vision problems.
