Description

[Technical field]

[0001] The present disclosure relates to roll screens. [Background technology]

[0002] In a conventional screen device, a movable frame is guided by a guide portion of the vertical frame of the screen frame and is given an opening force when it is pulled horizontally to open and close a screen stretched over the screen frame. A screen device in which the guide portion is provided with a notch for engaging the movable frame is known (see, for example, Patent Document 1).

[0003] In order to enable the movable frame to be locked in position with the screen stretched relative to the screen frame, the upper and lower horizontal frames are provided with cutouts for engaging the movable frame at corresponding positions of the guide sections where the movable frame is located when the screen is in the stretched state.

[0004] [Patent Document 1] JP 2008-14006 A Summary of the Invention [Problem to be solved by the invention]

[0005] The technology disclosed in Patent Document 1 provides locking notches on the visible surfaces of the guide section and the connecting member, which reduces the design of the roll screen. Furthermore, there is a concern that the design of the roll screen will be reduced if the movable frame rolls over significantly when it is locked into the notch. The movable frame is subjected to a biasing force that rolls up the screen, and there is a risk that the fixing force will be insufficient if the movable frame is only locked into one notch. In addition to the above, providing a notch in the guide section requires processing, which may increase costs.

[0006] The present disclosure has been made in consideration of the above, and has an object to provide a roll-up screen door that can securely fix a movable frame and also has a desirable design. [Means for solving the problem]

[0007] The present disclosure relates to a roll-up screen comprising a storage frame for rolling up and storing a mesh body, a frame member attached to the end of the mesh body pulled out of the storage frame, and a guide frame for slidably supporting both ends of the frame member, and having a first engagement portion provided on the outside of the room and engaging with a part of the frame member, and a rotation prevention portion provided on the inside of the room and preventing rotation of the frame member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] <Overall structure of roll screen> Hereinafter, an embodiment of the roll screen door of the present disclosure will be described with reference to the drawings. The roll screen door 1 is constructed by framing a storage frame 2 and a door stop frame 3 constituting a pair of vertical frames arranged on the left and right of a rectangular opening 100, and guide frames 4, 5 constituting a pair of horizontal frames on the top and bottom, in a rectangular shape so as to surround the opening 100 via connecting members 31, 32. A frame member 6 arranged parallel to the storage frame 2 is housed between the pair of guide frames 4, 5. A pull part 63 that protrudes toward the inside of the room is provided on the visible surface of the frame member 6 on the indoor side along the extension direction of the frame member 6.

[0010] In this specification, X1 in the drawings indicates the outdoor side and outdoor direction of the roll screen 1, and X2 indicates the indoor side and indoor direction of the roll screen 1. Y1 indicates the direction toward the storage frame 2 in the width direction of the roll screen 1. Y2 indicates the direction toward the door stop frame 3 in the width direction of the roll screen 1. Z1 indicates the upward direction of the roll screen 1, and Z2 indicates the downward direction of the roll screen 1. The front direction is the X1-X2 direction along the indoor / outdoor direction of the roll screen 1, and the front surface refers to the surface arranged along the indoor / outdoor direction. The front direction is the Y1-Y2 direction perpendicular to the indoor / outdoor direction of the roll screen 1, and the front surface refers to the surface arranged perpendicular to the indoor / outdoor direction and facing the indoor and outdoor sides, respectively. In the roll screen 1, the indoor side refers to the side in the X2 direction with respect to the sliding axis of the roll screen 1 in a plan view, and the outdoor side refers to the side in the X1 direction with respect to the sliding axis of the roll screen 1 in a plan view.

[0011] As shown in Figures 2 and 3, the roll screen door 1 is attached to a window 200 provided in a building frame. A paper screen 202 is housed in a rectangular frame 201 of the window 200 so as to be able to open and close. A frame member 203 is provided on the indoor side of the window 200 so as to surround the roll screen door 1. The roll screen door 1 is fixed to one visible surface 201a of the frame member 203 via an attachment 204. In the following explanation, the roll screen door 1 will be described as a horizontally sliding roll screen door that slides in the width direction of the window 200, but is not limited to this. The roll screen door 1 may also be a vertically sliding roll screen door that slides in the up and down direction of the window 200.

[0012] 2 and 3 is a horizontal sliding window that is configured so that the paper screen 202 opens by sliding out toward the outside around a horizontal axis (not shown) at the top. However, the window 200 to which the roll screen 1 is attached may be a window of other structure such as a vertical sliding window or a sliding window.

[0013] As shown in Fig. 2, the storage frame 2 of the roll screen 1 is disposed at one end of the guide frames 4, 5. The storage frame 2 stores the mesh body 7 wound in a roll so that it can be pulled out.

[0014] 2, the storage frame 2 is a vertically long box-shaped frame member capable of storing the mesh body 7. The storage frame 2 has a storage frame main body 21 attached to one end of the guide frames 4 and 5, and a cover member attached to the storage frame main body 21 in an openable and closable manner.

[0015] The guide frames 4, 5 extend in parallel from both the upper and lower ends of the storage frame 2 in the horizontal direction. The guide frames 4, 5 are provided with rails that slidably support both the upper and lower ends of the frame member 6. The rails are formed integrally with the guide frames 4, 5. When the frame member 6 slides in a direction away from the storage frame 2, the net body 7 is pulled out from the drawer opening of the storage frame 2 and extended. When the frame member 6 slides in a direction approaching the storage frame 2, the net body 7 is wound up on the winding shaft 71 and stored in the storage frame 2. The frame member 6 shown in FIG. 2 shows the open state of the roll screen door 1, in which the net body 7 is completely wound up on the winding shaft 71 and is closest to the drawer opening of the storage frame 2. The frame member 6 shown in FIG. 3 shows the closed state of the roll screen door 1, in which the net body 7 is pulled out to the outside of the storage frame 2 and locked closest to the door stop frame 3. The locking mechanism will be described in detail later.

[0016] The net body 7 is made of a net material, for example, made of resin threads woven into a net shape. The net body 7 is formed in a long strip shape extending in the left-right direction, and is formed into a roll by being wound around a winding shaft 71. The winding shaft 71 is biased in the direction of winding up the net body 7 by a biasing member (not shown), such as a spiral spring. The tip of the net body 7 is pulled out to the outside of the storage frame 2 from a pull-out opening arranged facing the guide frames 4 and 5, and is attached to the frame member 6.

[0017] <Roller screen locking mechanism> The roll screen door 1 has a locking mechanism that detachably locks the frame member 6, to which the tip of the mesh body 7 is attached, at a position adjacent to the door stop frame 3. The locking mechanism is realized by detachably locking a first locking portion provided on the connecting members 31, 32 that connect the door stop frame 3 and the guide frames 4, 5, with a second locking portion provided on the end caps 61, 62 provided on both the upper and lower ends of the frame member 6, and preventing the locked state from being released by an anti-rotation member.

[0018] The above-mentioned connecting members and end caps are essential components that make up the roll screen door 1. By providing a locking mechanism to the essential components of the roll screen door 1, there is no need to provide a new dedicated item, and the manufacturing costs of the roll screen door 1 can be reduced. In addition to the above, since no processing such as providing a notch in the rails themselves formed on the guide frames 4 and 5 is required, the manufacturing costs of the guide frames can be reduced and the locking mechanism can be formed without imposing restrictions on the position or installation direction of the guide frames. Furthermore, since the locking mechanism is formed in a position that is difficult to see from the outside of the connecting members and end caps, the design of the roll screen door 1 can be improved.

[0019] (Connecting parts) The connecting members 31, 32 are members that connect the guide frames 4, 5 and the door stop frame 3. The connecting members 31, 32 are made of, for example, resin. Below, the connecting member 32 that connects the lower end of the door stop frame 3 and the guide frame 5 will be described, but the connecting member 31 that connects the upper end of the door stop frame 3 and the guide frame 4 also has a similar configuration.

[0020] 4 and 5, the connecting member 32 has a connecting portion 323 to which the door stop frame 3 is connected, and a connecting portion 324 to which the guide frame 5 is connected. The connecting portion 323 is inserted into the inside of the door stop frame 3 configured in a hollow cylindrical shape and fixed therein, thereby connecting to the door stop frame 3. The connecting portion 324 is inserted into a hollow portion formed below the rail 52 of the guide frame 5 and into a space formed by the rail guide 51 and the rail 52, thereby connecting to the guide frame 5.

[0021] As shown in Figs. 5 and 6, the connecting portion 324 has a first locking portion 321 and a rotation prevention portion 322. The first locking portion 321 is locked with a second locking portion 621a described later, thereby locking the frame member 6 at a position close to the door stop frame 3 against the biasing force applied to the frame member 6. In the locked state, the rotation prevention portion 322 abuts against an extension portion 622 described later, thereby preventing the frame member 6 from rotating in the horizontal direction due to the biasing force and releasing the locked state. The first locking portion 321 and the rotation prevention portion 322 are inserted and arranged in a space formed between the rail 52 and the rail guide 51 provided on the outside thereof. The first locking portion 321 is provided on the outside of the room, and the rotation prevention portion 322 is provided on the inside of the room.

[0022] The first locking portion 321 and the rotation prevention portion 322 are convex portions formed on the inner surface of the connecting portion 324. FIG. 6 is a plan view showing a state in which the connecting member 32 and the guide frame 5 are connected. As shown in FIG. 6, the first locking portion 321 and the rotation prevention portion 322 are formed so as to protrude from each other toward the rail 52 in a state in which the connecting member 32 is connected to the guide frame 5. The first locking portion 321 is configured so that the width of the Y2 direction end is wide and the width of the Y1 direction is narrow. The Y2 direction end of the first locking portion 321 is formed so as to have a step between it and the connecting portion 324, and the Y1 direction end of the first locking portion 321 is formed so as not to have a step between it and the connecting portion 324. Therefore, as shown by the white arrow in FIG. 4, when the end cap 62 is brought close to the connecting member 32 from the Y1 direction and engaged with the second locking portion 621a provided on the end cap 62, it is configured so as to be easily engaged and difficult to come off. The rotation prevention portion 322 has a similar configuration.

[0023] (end cap) End caps 61, 62 are attached to both the upper and lower ends of the frame member 6. The end caps 61, 62 are made of, for example, resin. In the following explanation, the end cap 62 provided at the lower end of the frame member 6 and the guide frame 5, which is a horizontal frame disposed at the lower part, will be described, but the end cap 61 provided at the upper end of the frame member 6 and the guide frame 4 also have the same configuration.

[0024] As shown in Figures 4 and 7, the end cap 62 has an engagement portion 624 on one surface that abuts against the guide frame 5. The engagement portion 624 is formed by bending two pairs of protruding tip portions so that they approach each other. The engagement portion 624 engages with the rail 52 formed on the guide frame 5. The rail 52 is made up of two pairs of extension pieces that extend upward, and the tip portions of the two pairs of extension pieces are bent so that they move away from each other. By engaging the engagement portion 624 with the rail 52, the frame member 6 is slidably supported relative to the guide frames 4, 5.

[0025] The end cap 62 is provided with a second locking portion 621a that is locked with the first locking portion. FIG. 7 is a view of the end cap 62 viewed from the bottom side. As shown in FIG. 7, the second locking portion 621a is provided at one end of the engagement portion 624. The one end is the end on the outside of the room. That is, the second locking portion 621a is disposed on the outside of the roll screen door 1. The second locking portion 621a is a pair of extension pieces formed by extending the end opposite to the direction in which the end of the engagement portion 624 is bent in the horizontal direction. The pair of second locking portions 621a are formed so that one end toward both ends in the viewing direction is inclined so as to be narrow, and the other end toward the center of the base material is wide, and has a step between the engagement portion 624. Therefore, the pair of second locking portions 621a is formed so that the first locking portion is easily locked between the pair of second locking portions 621a and is difficult to come off.

[0026] An extension 622 is formed on the other end of the end cap 62, which is different from the end where the second locking portion 621a is formed. The extension 622 is arranged on the indoor side of the roll screen 1. Like the second locking portion 621a, the extension 622 is formed by extending the end opposite to the direction in which the end of the engagement portion 624 is bent in the horizontal direction. The extension 622 is formed so that one end toward the door stop frame 3 is wide, and the other end is inclined so that the width becomes narrower. When the first locking portion and the second locking portion are locked, the inclined end surface of the extension 622 abuts against the rotation prevention portion 322.

[0027] In this way, the locking mechanism of the roll screen door 1 of the present disclosure is configured to maintain a locked state at two locations, one on the indoor side and one on the outdoor side. This makes it possible to prevent the roll screen door 1 from being unintentionally unlocked. In addition to the above, all of the locking mechanisms of the roll screen door 1 are located inside the guide frame 5, which is difficult to see. This makes it possible to improve the design of the roll screen door 1.

[0028] Next, the operation of engaging the first locking portion 321 with the second locking portion 621a and locking the frame member 6 at a position close to the door stop frame 3 will be described. In order to close the roll screen door 1, a user (hereinafter simply referred to as "user") who operates the roll screen door 1 grips the handle portion 63 of the frame member 6 and slides the frame member 6 from the Y1 direction to the Y2 direction. When the frame member 6 is slid to a position close to the door stop frame 3, one of the pair of second locking portions 621a provided on the end cap 62, which is disposed on the Y2 direction side, abuts against the first locking portion 321. In this state, when the user further applies a normal force in the Y2 direction, one of the second locking portions 621a moves over the first locking portion 321 and moves to the Y2 direction side. As a result, the end of the first locking portion 321 on the Y2 side and the end of one of the second locking portions 621a on the Y1 side come into contact with each other and are locked against the biasing force applied to the frame member 6 in the Y1 direction.

[0029] In the locked state, a biasing force in the Y1 direction is applied to the frame member 6. Therefore, if an external force is applied to the frame member 6 or the mesh body 7, there is usually a risk that the locked state may be released unintentionally. However, in the locked state, the rotation prevention portion 322 and the end face of the extension portion 622 abut against each other, preventing rotation of the frame member 6. Therefore, it is possible to prevent the locked state of the roll-up screen door 1 from being released unintentionally.

[0030] Next, the operation for releasing the locked state between the first locking portion 321 and the second locking portion 621a will be described. To release the closed state of the roll screen door 1, the user grips the handle portion 63 of the frame member 6 and rotates it in the Y1 direction, i.e., clockwise in a plan view. This releases the locked state between the first locking portion 321 and the second locking portion 621a. Therefore, the user can move the frame member 6 in the Y1 direction according to the biasing force in the Y1 direction applied to the frame member 6, and open the roll screen door 1.

[0031] When the frame member 6 is rotated clockwise in a plan view, the end cap 62 is rotated in the direction of the arrow y1 shown in FIG. 7. As a result, the second locking portion 621a is moved to a position where the end of the first locking portion 321 on the Y2 side and the end of one of the second locking portions 621a on the Y1 side do not abut each other. As a result, the locking state of the first locking portion 321 and the second locking portion 621a is released. At this time, the rotation prevention portion 322 and the end face of the extension portion 622 abut each other. However, the rounded end face of the extension portion 622 can be rotated along the rounded end face of the rotation prevention portion 322. The above rotational movement can be performed by the normal force of the user. As a result, the locking state of the roll screen door 1 can be released only when the user intends to do so.

[0032] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the contents of the above-described embodiments, and can be modified as appropriate within the scope of the gist of the present disclosure.

[0033] The storage frame 2 of the roll screen door 1 described above constitutes the vertical frame of the roll screen door 1. However, the storage frame may constitute either the upper or lower frame of the roll screen door. In this case, the guide frame constitutes the left and right vertical frames. The net is pulled out in the vertical direction from the storage frame.

[0034] The storage frame 2 of the roll-up screen door 1 described above is disposed on only one of the left and right sides of the opening 100. However, the roll-up screen door 1 may be a double-pull type in which the storage frame 2 is disposed on each of the left and right sides of the opening 100. [Explanation of symbols]
