Description

  The present invention relates to a screen device in which a screen can be opened and closed horizontally by a movable rod that slides along the upper and lower horizontal frames of the screen frame. Specifically, the screen is wound around a winding shaft. The present invention relates to a winding screen device.

  In a horizontally-drawing screen device attached to the opening of a building, a movable rod slidable along the upper and lower horizontal frames, a screen that is opened and closed by the movable rod, and a screen supported by a take-up box are attached. The one having a winding shaft to be used is conventionally known. In this type of screen device, for example, as disclosed in Patent Document 1, a spring is incorporated in the winding shaft so as to be spring-biased in the screen storage direction, whereby the screen is placed on the winding shaft. An automatic storage type that can be wound is generally used.

  By the way, in such a conventional roll-up screen device, the screen is always urged in the storage direction of the screen. Therefore, when the movable rod is operated and the screen is pulled out in the extending direction, this urging force is applied. Requires resistance. Further, when the screen is extended and held in the fully extended state, a latch mechanism must be provided for the movable rod and the receiving frame. This latch mechanism uses the magnet's attracting force, but in this case, the balance between the spring's biasing force and the magnet's attracting force is considered, and the movable rod and the receiving frame are not fixed securely. Therefore, it is necessary to have a suction force that does not cause the release. In addition, there is a type in which either one of the movable rod and the receiving frame is provided with a hook and the other is provided with a hook that engages with the hook, but this type resists the biasing force of the spring. However, it is necessary to perform the engagement and the release thereof, and the structure becomes complicated in order to eliminate the trouble.

  Then, for example, a user such as a child with weak power operates the movable rod to expand the screen, or from the state where the screen is held in the fully extended state, the relationship between the movable rod and the receiving frame is reached. There was a risk that it would be difficult to cancel the match. Simply, if there is no spring biasing means, this problem will be eliminated. In that case, it seems that there is no problem when the screen is expanded, but conversely, when the screen is stored, the screen Since no tensile force acts on the screen, the screen loosens, and it becomes very difficult to wind the screen around the winding shaft along with the sliding of the movable rod. End up.

1 to 4 show an embodiment of a winding screen device according to the present invention.
The winding screen device 1 of this embodiment includes a screen frame 2 attached to a building opening, a movable rod 5 slidable along upper and lower horizontal frames 3 and 4 of the screen frame 2, and the movable rod. 5 and a winding box 7 in which a winding shaft 8 around which the screen 6 is wound is supported.

  The screen frame 2 is configured such that one of the left and right vertical frames in the screen frame 2 is configured as the winding box 7, and the other vertical frame hits the movable rod 5 when the screen 6 is extended. It is configured as a receiving frame 9. The screen frame 2 is configured by connecting the upper and lower portions of the winding box 7 and the receiving frame 9 to the upper horizontal frame 3 and the lower horizontal frame 4 with a connecting member 10.

  The upper and lower horizontal frames 3 and 4 hold and guide the side edges of the screen 6 (upper and lower ends in FIG. 1), and are each made of a groove-shaped mold material that opens to the screen 6 side as shown in FIG. A pair of ribs 3a, 3b and 4a, 4b facing inward are formed at the mouth edges of these openings. The outer surfaces of the ribs 4 a and 4 b of the lower horizontal frame 4 form a rolling surface of a pair of left and right rolling wheels 11 provided at the lower end of the movable rod 5.

  The screen 6 is formed of an appropriate material depending on the application, such as a net suitable for insect repellent, a net or sheet having a good light shielding property, and a net or sheet suitable for blinding. One end of the screen 6 is detachably fixed to the winding shaft 8 by a well-known means, and the other end of the screen 6 is detachably fixed to the movable rod 5 via an attachment member 12. For this fixing, as shown in FIG. 3A, a mounting groove 13 extending in the axial direction of the movable rod 5 is formed on the side facing the winding box 7 of the movable rod 5. This is done by elastically fitting the mounting member 12 inside.

  As shown in FIG. 3A, the receiving frame 9 has an abutting surface 9 a against which the movable rod 5 abuts when the screen 6 is fully stretched. Further, the receiving frame 9 is formed with a pair of side walls 9b, 9b standing from the abutting surface 9a toward the movable rod 5, so that the cross section is formed in a substantially U shape. The side walls 9b, 9b have a slope shape that expands toward the movable rod 5, and the side of the movable rod 5 that faces the receiving frame 9 corresponds to the slope shape on both side walls of the receiving frame 9. A portion thereof is tapered toward the receiving frame 9 so as to be fitted between 9b and 9b.

  The winding box 7 rotatably supports the winding shaft 8 at the upper and lower ends of the winding box 7 by a shaft support portion (not shown) formed on the surface facing the inside of the box 7. As shown in FIGS. 1 and 4, the take-up shaft 8 disposed in the take-up box 7 has a screen take-up portion 14 on which one end of the screen 6 is fixed and the screen 6 is taken up substantially. It is comprised from the cap part 15 provided in the both ends and rotatably supported by the said shaft support part. The cap portion 15 includes a reel portion 16 around which a wire, which will be described later, is wound, and a body portion 17 provided with the shaft support portion continuous with the reel portion 16. And the center axis line of the trunk | drum 17 of the said cap part 15 and the said screen winding-up part 14 is match | combined, and they are connected and fixed. Thus, the reel portion 16 is arranged concentrically with the axis of the screen winding portion 14 and is formed to rotate integrally with the screen winding portion 14.

  In the present embodiment, the take-up shaft 8 is configured by combining the screen take-up portion 14 and the cap portion 15, but is not limited thereto, and the reel portion 16 in the cap portion 15 is separated. After being molded as a body, it can also be integrated during assembly.

  Ends of the first and second wires 18 and 19 are fixed to the upper and lower ends of the movable rod 5, respectively, and these wires are formed between the upper and lower ends inside the movable rod 5. In the vicinity of the upper and lower mouth edges of the hollow portion 20, the ends of the wires 18 and 19 are fixed by appropriate means such as screws. The proximal ends of the wires 18 and 19 are led from the vicinity of the mouth edge of the cavity 20 to the receiving frame 9 side along the upper and lower horizontal frames 3 and 4, respectively. The connecting member 10 disposed on the upper and lower portions of the receiving frame 9 also serves as a turning guide for the wires 18 and 19 as can be seen from FIGS. 1 and 3B, and the first and second wires 18 , 19 are turned about 180 degrees toward the winding box 7 along the turning surface 10a of the connecting member 10 curved in a substantially U-shaped cross section.

  The two wires 18, 19 turned back at the turning surface 10 a of the connecting member 10 are guided to the winding box 7 side along the upper and lower horizontal frames 3, 4, and are then laterally moved in the vicinity of the winding box 7. Guided by the guide wall 10 b of the connecting member 10 projecting into the frames 3, 4, smoothly guided into the winding box 7 and wound around the reel portion 16 of the winding shaft 8. As shown in FIG. 4, the reel portion 16 of the winding shaft 8 around which the base ends of the wires 18 and 19 are wound is detached from the wire winding surface 16a at both ends in the width direction of the wire winding surface 16a. A pair of flanges 16b, 16b are formed to prevent the above.

  As shown in FIGS. 3A and 3B, the first and second wires 18 and 19 are wound around the reel portion 16 in a direction opposite to the winding direction of the screen 6. . That is, when viewed from the upper horizontal frame 3 side, the screen 6 is wound around the screen winding portion 14 in a left-handed manner. However, the first and second wires 18 and 19 are opposite to the winding direction. The reel unit 16 is wound right-handed.

  As described above, when the screen 6 and the wires 18 and 19 are wound around the winding shaft 8 in the opposite directions, when the movable rod 5 is operated to slide the screen 6 in the extending direction. As the screen 6 is unwound, the screen take-up portion 14 rotates counterclockwise in FIG. 3A, and the reel portion 16 is integrated with the rotation (FIG. 3B). ), The rotational force in the direction of winding the upper and lower wires 18, 19 is applied to the reel portion 16 of the winding shaft 8 through the screen 6. When the screen 6 is wound in the sliding direction of the screen 6, the first and second wires 18 and 19 connected to the movable rod 5 are unwound from the reel portion 16, and the movable rod 5 is moved. Gives a rotational force in the winding direction of the screen 6 to the screen winding portion 14 of the winding shaft 8 through the wires 18 and 19, thereby preventing the screen 6 from being bent. 14 is wound up.

  Since the winding direction of the screen 6 with respect to the screen winding portion 14 of the winding shaft 8 and the winding directions of the upper and lower wires 18 and 19 with respect to the reel portion 16 are opposite to each other, for example, the movable rod 5 is operated. When the screen 6 is moved in the extending direction, the length of the screen 6 fed out according to the rotation angle of the winding shaft 8 and the winding amount of the wires 18 and 19 may differ depending on the position of the movable rod 5. As a result, the screen 6 and the wires 18 and 19 may be slightly slackened during the movement of the movable rod 5, but if this slackness is increased, the wires 18 and 19 It is also possible to attach a slack absorbing mechanism by attaching an elastic member that elastically expands and contracts to the part.

  Thus, in the winding screen device 1, since the spring biasing means is not provided on the winding shaft 8, the movable rod 5 can be slid with a small force, and the screen 6 can be moved easily. Further, in connection with maintaining the screen 6 in the fully extended state, when a fixing means such as a latch mechanism is attached to the movable rod 5 and the receiving frame 9, the engaging force resists the spring bias. Therefore, it is sufficient that the fixing can be easily and easily released. Even when the movable rod 5 is operated and stopped between the winding box 7 and the receiving frame 9 and held at that position, no additional member is required and no special structure is applied. It is possible to hold the screen in a position desired by the user.

  When the first and second wires 18 and 19 are disposed at the upper and lower ends of the winding shaft 8 as described above, the movable rod 5 can be translated by the wires 18 and 19. The first and second wires 18 and 19 can also constitute a translation mechanism for the movable rod.

  As mentioned above, although one Example of the winding type screen apparatus 1 which concerns on this invention has been described in detail, this invention is not limited to the said Example, In the range which does not deviate from the summary of this invention, it is various. Design changes are possible.
