Description

screen device

The present invention relates to a screen device applied to light shielding and light control means such as curtains and blinds, screen doors, partitions, and the like.

Conventionally, this type of screen device generally includes a screen that can be freely deployed and retracted, and at least one of which is slidable in the X-axis direction, with the direction of deployment and retraction of the screen being the X-axis direction of the three orthogonal axes. A first frame fixed to one end of the screen in the X-axis direction and a second frame to which the other end of the screen in the X-axis direction is fixed, which are arranged to face each other in the X-axis direction and are long in the Z-axis direction and hollow When the slidable frame is slid in one direction of the X-axis, the slidable frame is pulled out from the inside of the slidable frame in the other direction of the X-axis, and the slidable frame is slid in the other direction of the X-axis. A portion of the slidable frame that is housed inside the slidable frame, has a free end at one end, and is pulled out from the inside of the slidable frame is positioned between one end of the pair of frames in the Z-axis direction and the Z-axis. A first guide and a second guide linearly extending in the X-axis direction between the other ends of the direction, respectively, and a tension member provided inside the slidable frame to connect the free ends of the first guide and the second guide. and a member.

And in EP 2 333 229 A1, the first guide is formed by connecting a plurality of first guide units, each first guide unit being pulled out from the inside of the stile in which the first guide is slidable. , a pair of side walls arranged to face each other in the Y-axis direction, and a bottom wall connecting the side walls. It is pivoted to the other first guide unit, and by this pivoting, the first guide maintains linearity in the X-axis direction, while bending in the other Z-axis direction, so that the inside of the slidable frame of the first guide A screen device is described in which one end in the Z-axis direction of an unfolding screen is inserted between both side walls of each first guide unit in a portion pulled out from the opening.

In the above screen device, at one end in the X-axis direction of both side walls of each first guide unit corresponding to one end in the Z-axis direction of the first guide pulled out from the slidable frame, A pair of pins directed in the direction are provided, and a pair of openings are formed at the other end in the X-axis direction. are connected by a loose fit of the pins, and both pins form a pivot.

In addition, in the above screen device, rigid projections are provided on both side walls of each first guide unit on the side where the pins are provided so as to protrude inward in the opposite direction of both side walls. In the first guide, the rigid projection extends along the imaginary line in the plane including the imaginary line connecting the centers of the pivots of the first guide units to the coupling direction of the first guide units. When the first guides are pulled out in the other X-axis direction as the slidable frame slides in one direction, the rigid protrusions are formed on both sides of each first guide unit in the portion where the first guides are pulled out. Even if the other end in the Z-axis direction of the screen inserted between the walls is stuck and the unfolded screen receives an external force such as wind pressure, the one end in the Z-axis direction of the screen will not come out of the pulled-out portion of the first guide. Hold it so that it does not come off.

However, although they are rigid protrusions, each first guide unit is generally an integrally molded product made of resin, and as the screen is deployed and retracted, it repeatedly sticks into and comes off from one end of the screen in the Z-axis direction. , rigid projections have problems such as being bent and deformed, or being broken and damaged. Also, the type of screen is generally changed depending on the application, installation location, and the like of the screen device. Therefore, if the molding material of each of the first guide units is stronger than the screen, there is a risk that one end of the screen in the Z-axis direction will be damaged when the rigid projection pierces the screen. In order to prevent the screen from being damaged, in the case of the above screen device, it is necessary to prepare a plurality of types of first guide units using materials corresponding to the types of screens. As a result, the first guide also has a plurality of types.

In view of the above points, the present invention is capable of suppressing breakage of one end of the screen in the Z-axis direction on the side inserted into the first guide even when the screen is repeatedly deployed and retracted, and is capable of It is therefore an object of the present invention to provide a screen device capable of forming a first guide with only one type of first guide unit.

In order to solve the above-mentioned problems, the present invention provides a screen which can be freely deployed and retracted, and at least one of which is slidable in the X-axis direction, with the direction of deployment and retraction of the screen being the X-axis direction of the three orthogonal axes. A first frame to which one end of the screen in the X-axis direction is fixed and a second frame to which the other end of the screen in the X-axis direction is fixed are arranged to face each other in the X-axis direction. When a pair of stiles consisting of stiles and a slidable stile are slid in one direction of the X-axis, the slidable stile is pulled out from the inside of the slidable stile in the other direction of the X-axis, and the slidable stile is slid in the other direction of the X-axis. When this is done, the part that is housed inside the slidable stile and has a free end at one end and that is pulled out from the inside of the slidable stile extends between the ends of the pair of stiles in the Z-axis direction and the Z A first guide and a second guide extending linearly in the X-axis direction between the other ends in the axial direction, respectively, are provided inside the slidable frame and connect the free ends of the first guide and the second guide. a tension member, wherein the first guide is formed by the connection of a plurality of first guide units, each first guide unit being extended when the first guide is withdrawn from the interior of the slidable stile. , a pair of side walls arranged to face each other in the Y-axis direction, and a bottom wall connecting the side walls. It is pivoted to the other first guide unit, and by this pivoting, the first guide maintains linearity in the X-axis direction, while bending in the other Z-axis direction, so that the inside of the slidable frame of the first guide One end in the Z-axis direction of the unfolding screen is inserted between both side walls of each first guide unit in the portion pulled out from is provided with a pair of pins extending outward in the facing direction of both side walls, and a pair of openings are formed at the other end in the X-axis direction, and two adjacent first guide units are connected to one of the first guide units. The pins of the other first guide unit are loosely fitted into the respective openings of the first guide unit, the two pins form pivots, and rail portions are provided on the inner side portions of both side walls of each first guide unit in the opposing direction. This rail portion extends along the imaginary line in the plane including the imaginary line connecting the centers of the pivots of the first guide units in the connecting direction of the first guide units, and extends from the bottom wall to the Z-axis rather than the rail portion. On the edges of both walls away in the other direction, A support piece projecting inward in the direction is provided, and a large number of needle-like portions are attached to the long base portion of each first guide unit which is bendable in the pivoting direction and spaced apart from each other. , and is detachably mounted on both side walls of each first guide unit on the inner side in the facing direction, and the base portion is supported between each rail portion of each first guide unit and each support piece in the mounted state of the screen retaining member. At the same time, all the needle-like portions protrude inward in the opposite direction of both side walls of each first guide unit, and the first guide is pulled out in the other X-axis direction as the slidable frame slides in one direction in the X-axis direction. When the screen is pulled out, the needle-shaped portion of each screen retaining member pierces one end in the Z-axis direction of the screen inserted between both side walls of each first guide unit in the portion where the first guide is pulled out, and the screen is While the first guide cannot be removed from the pulled-out portion, each screen retains when the first guide is housed inside the slidable frame as the slidable frame slides in the other X-axis direction. It is characterized in that the needle-like portion of the member can be removed from one end portion of the screen in the Z-axis direction.

According to the present invention, it is possible to prepare in advance a plurality of types of screen retaining members each having a large number of needle-like portions attached to the base corresponding to the type of screen. An appropriate one can be selected from among them and mounted on the inner side portions of both side walls of each of the first guide units of the first guide in the opposing direction. It is possible to suppress breakage of one end in the Z-axis direction of the screen inserted between both side walls of the first guide unit forming the 1 guide. Moreover, it is not necessary to manufacture a first guide unit for each type of screen, and the first guide can be formed with only one type of first guide unit.

In the present invention, the both side walls of each of the first guide units extend in the same direction as the portion of the first guide that extends in the X-axis direction from the inside of the slidable frame, and face each other. At one end of the slidable frame in the Z-axis direction, curved protrusions curved with a predetermined curvature are provided on a pair of inner side surfaces facing each other in the Y-axis direction.
