Description

The present invention relates to a roll SCREEN WakuSo location and sash provided on windows and Patenshon like buildings sunshade or rain except or purpose of privacy blindfolded like, particularly, shielding or blind height and area arrangement of the screen and upper and lower openable roll SCREEN WakuSo location was to be freely changed in accordance with the intended change in equal relates sash using the vertical retractable roll SCREEN WakuSo location.

  As a conventional general roll screen device, a winding shaft attached to the upper part of a building window, a sheet-like screen suspended around the winding shaft, and a screen for feeding the screen downward from the winding shaft. An operation cord, a bottom pipe that supports the lower end of the screen drawn downward from the winding shaft, a spring that constantly urges the screen in the winding direction inside the winding shaft, and the winding shaft A clutch mechanism for controlling the rotation of the take-up shaft is known, and the clutch mechanism stops the screen pulled out from the take-up shaft against an urging force of a spring at an arbitrary position. In addition, the stopped state by the clutch mechanism is released, and the screen is wound around the winding shaft by the biasing force of the spring (see, for example, Patent Document 1). ).

  In addition, a lifting / lowering cord for the winding shaft is inserted into the winding shaft, and two intermediate portions of the lifting / lowering cord are pulled out above the winding shaft and passed over a pulley provided on the upper frame of the window frame to wind up. A blind has also been proposed in which only the lower portion of the window can be covered by operating the end of the lifting / lowering cord drawn downward from one end of the shaft to raise and lower the winding shaft (for example, Patent Document 2).

Japanese Patent No. 2860230 Japanese Utility Model Publication No. 63-156399

  In the roll screen device of Patent Document 1, the winding shaft is fixed to the upper wall of the building window or the upper frame of the window frame, and the screen is suspended around the winding shaft. Even when it is desired to shield only a part of the lower part away from the take-up shaft, there is a problem that the entire part from the take-up shaft to the target shield portion must be covered with a screen. Further, in Patent Document 1, since the upper part which is not intended to be shielded is shielded by a screen, daylighting and heat gathering are hindered, resulting in an adverse effect that the room becomes darker or colder than necessary.

The blind of Patent Document 2 is designed to eliminate the drawbacks of Patent Document 1 described above by allowing the winding shaft to move up and down. However, the blind and bottom pipe of Patent Document 2 are suspended from the winding shaft. For this reason, when the winding shaft is raised and lowered, the bottom pipe is also raised and lowered integrally. Therefore, it is difficult to position the blind, that is, to set the blind to the required size at the required height.
In addition, the large blinds are large and heavy in a large window, but the lifting cord of the winding shaft is subject to the load of the winding shaft, blind and bottom pipe. The difficulty of having to operate is expected.

  Furthermore, in Patent Document 2, a lift lock device is provided inside the take-up shaft in order to stop the take-up shaft at an arbitrary position. This lift lock device stops the take-up shaft by gripping the lifting / lowering cord. Therefore, similarly to the raising and lowering of the winding shaft, the loads of the winding shaft, the blind and the bottom pipe act on the lift lock device through the lifting cord. For this reason, if the lift lock device has a simple structure in which the lifting / lowering cord is gripped by a frictional force, it is expected that the lifting / lowering cord will slip and the winding shaft will slide down, and the lifting / lowering cord will be securely gripped. It is expected that the lift lock device will be enlarged and it will be difficult to accommodate it on the take-up shaft.

  Moreover, since the blind of patent document 2 only hang | suspends the whole winding shaft, a blind, and a bottom pipe with a raising / lowering cord, stability is unsatisfactory, and when they raise / lower, these shake, and operativity is impaired. In particular, it is effective to dispose the screen device outside a window that is outdoors in order to block sunlight and prevent an increase in indoor temperature. There is a risk that the take-up shaft, blinds, and bottom pipe may be beaten or fluttered by wind or other external forces, which further hinders the raising and lowering of the take-up shaft and bottom pipe.

The present invention has been made against the background of such circumstances, and the object of the present invention is to allow the screen to be arranged only in the position and the width according to the purpose such as shading or blindfolding, and the above-mentioned patent document. It lies in providing a sash with vertical retractable roll SCREEN WakuSo location capable of resolving the second problem with this vertical retractable roll SCREEN WakuSo location.

In order to achieve the above object, an up-and-down open / close type roll screen frame device of the present invention includes a frame-shaped guide frame having side frames on both sides, an upper side inside the guide frame, and both side ends inside the side frame. A take-up shaft that is housed in a transverse manner, a sheet-like screen suspended around the take-up shaft, and a biasing means that constantly biases the screen in the take-up direction inside the take-up shaft. A bottom pipe that supports the lower end of the screen drawn out from the winding shaft at the lower inside of the guide frame, and that is horizontally placed with both side ends housed in the side frame, and the winding shaft a first operating means for operating the take-up shaft lifting means and the take-up shaft lifting means is wound lift and a bottom pipe lifting means and the second operating means for driving the Botomupai flop lifting hand stage lifting the bottom pipe , The side frame Winding shaft lifting guide means for guiding the lifting and lowering of the winding shaft along the side frame, and the bottom pipe is disposed inside the prospective direction of the guide frame. in and then laterally placed to find the direction of the guide frame, each of said winding shaft and the bottom pipe with eggplant freely alone lifting, either one or the other of the take-up shaft and the bottom pipe, each of the other party The screen can be stretched to an arbitrary height of the guide frame in an arbitrary area by approaching and moving away from each other.

The winding shaft raising / lowering guide means may comprise a guide roller pivotally supported by a spindle projecting from both ends of the winding shaft, and a guide rail that guides the guide roller in the vertical direction inside the side frame. it can.

Vertically retractable roll SCREEN WakuSo location of the present invention, the winding shaft turn suspended the screen within the upper guide frame, between the side frames via a winding shaft lifting means by the operation of the first operating means The bottom pipe carrying the lower end of the screen on the lower side inside the guide frame is raised and lowered while being guided between the side frames via the bottom pipe raising / lowering means by the operation of the second operating means, A screen is disposed between the winding shaft and the bottom pipe.

  The spread area of the screen varies depending on the distance between the winding shaft and the bottom pipe, and the height at which the screen is arranged varies depending on the stop position of the winding shaft and the bottom pipe. Since the urging means inside the winding shaft always acts on the screen in the winding direction, the screen is stretched between the winding shaft and the bottom pipe without slack.

The winding shaft and the bottom pipe are moved to arbitrary heights inside the guide frame by the operation of the first operating means and the second operating means, respectively, and the screen is adapted to the purpose such as shading or blindfolding inside the guide frame. The required area (height) is arranged in the required position (height).
If you want to change the position (height) or width (area) of the screen, change the height position of the winding shaft and bottom pipe by operating the first operating means and the second operating means. Correspondence is possible.

  As described above, the screen according to the present invention is arranged at a necessary minimum size at a position corresponding to a purpose for shielding or blinding a window or a partition. Therefore, it is not necessary to spread the screen in a place where shielding is unnecessary or where it is not desired to shield. Thereby, the lighting and heat collection into the room is not disturbed unintentionally, and the problem that the room becomes darker or colder than necessary is eliminated.

Further, the upper and lower retractable roll SCREEN WakuSo location of the present invention is applied to a portion of a window or Patenshon or glass wall, the screen windows and Patenshon, by positioning an intermediate portion of the glass wall, divide these upper and lower portions It is possible to use it by releasing it, or by positioning it at the lower part of the window, the tension or the glass wall and releasing the upper part and the middle part continuously.

Furthermore, the upper and lower openable roll SCREEN WakuSo location of the present invention, since the raising and lowering of each of the take-up shaft and the bottom pipe alone regardless of the other, blind positioning is facilitated. Further, since both side ends of the winding shaft and the bottom pipe are positioned inside the side frame, the winding shaft and the bottom pipe move up and down along the side frame.
When raising or lowering one of the winding shaft and bottom pipe approaches the other, only one's own load acts on one, and when raising or lowering one of them away from the other, the load and screen are pulled out to one side. It only takes the resistance. Therefore, both the winding shaft and the bottom pipe can be easily operated with a small force.

Also, the sash of the present invention is characterized by comprising any one of the upper and lower openable roll SCREEN WakuSo location of the present invention described above. In this case, the upper and lower retractable roll SCREEN WakuSo location on one side of the sash provided integrally or separately. Sash is assembled to the opening of the sash mounting, which opened in the wall of the building, also roll SCREEN WakuSo location is arranged outside the wall of a building.

According to vertically retractable roll SCREEN WakuSo location of the present invention, since the raising and lowering each of the take-up shaft and the bottom pipe is easy screen positioning, purpose of screen hidden shading and eye windows and Patenshon It is possible to easily set the required area at a position corresponding to
Also, when moving up and down the take-up shaft and bottom pipe, when either the take-up shaft or the bottom pipe approaches the other, only one load acts on one, and either one is separated from the other. In raising and lowering, one side only has its own load and resistance to pull out the screen. Therefore, even in roll SCREEN WakuSo location is large, both of the winding shaft and the bottom pipe can be easily operated with a small force.

Furthermore, since the winding shaft and the bottom pipe each move up and down along the side frame, the winding shaft and the bottom pipe are excellent in stability, and there is no problem that the winding shaft and the bottom pipe sway during the lifting and lowering. Therefore, the roll screening when the emissions WakuSo location is disposed outside the window is outdoors, the winding shaft and the bottom pipe by wind or other external forces, and effectively prevent the flutter or blinds fanned, wound The influence of raising and lowering the take-up shaft and the bottom pipe can be suppressed as much as possible.
In addition, the take-up shaft and the bottom pipe are held in the raising / lowering position by being connected to the take-up shaft raising / lowering means and the bottom pipe raising / lowering means, so there is no need to provide a clutch mechanism or a lift lock device on the take-up shaft. The shaft can be made light and simple, and the winding shaft can be raised and lowered with a lighter operation.

Furthermore, the winding shaft lifting guide means for guiding along a side frame of the lifting of the winding shaft, set by positioning on the indoor side and the outdoor side of the interior of the side frame Ketari, the winding shaft lifting guide means The combination of a guide roller pivotally supported by a spindle projecting from both ends of the winding shaft and a guide rail that guides the guide roller in the vertical direction inside the side frame makes it possible to raise and lower the winding shaft. It can be performed stably without blurring.
