Description

  The present invention relates to a horizontal screen device that realizes an opening and closing operation by an operation of folding a flexible screen sheet in a zigzag manner and an operation of unfolding it in a flat shape, and particularly for a screen sheet in an unfolded state. It relates to things that give a certain tension.

A shutter mechanism or a screen mechanism is used for opening / closing an entrance / exit of a large retail store or the like, or for protecting an entrance / exit and a glass surface or a wall surface during the closing time. For example,
Japanese Utility Model Publication No. 5-17086 JP 2003-138861 A JP 2003-239655 A JP 2004-107886 A JP 2007-154425 A

  The shutter mechanism has a box section or a single plate-like panel member in a horizontal posture and is connected to bend a large number in the vertical direction, and the connected panel member is raised or lowered along guide rails arranged on the left and right of the panel member. Opening and closing operations are realized by lowering (see Patent Documents 1 and 2).

    Further, the screen mechanism suspends a flexible sheet member or a large number of vertical panel members connected in a horizontal direction so as to be horizontally movable from a hanger rail on the ceiling side, and this is suspended on one end side of the hanger rail. Opening and closing operations are realized by pulling them up or unfolding so as to spread in the longitudinal direction of the hanger rail (see Patent Documents 3, 4, and 5).

  The shutter mechanism is a mechanism that is frequently used in a portion having a relatively small frontage width such as an entrance / exit of a commercial building. In this shutter mechanism, the positioning of the connected panel depends only on the guide rails at the left and right ends, and the intermediate part cannot be supported, so it is difficult to apply to the front part having a certain width or more. There is a problem that there is. However, it is possible to deal with frontage that exceeds a certain width by installing multiple shutter mechanisms. However, in this case, it is necessary to install a guide rail at the intermediate position. In this case, it is necessary to carry out complicated installation and removal work of the intermediate guide rail.

  Further, in the shutter mechanism, since the opening / closing operation is performed by the ascending or descending operation of the connected panel, the connected panel pulling mechanism or winding mechanism and the storage space for the panel are provided on the ceiling side. Since it needs to be provided, there is also a problem that the content of the installation work to an existing building becomes difficult or very complicated.

  On the other hand, the screen mechanism is constructed such that a flexible screen sheet can be folded between a large number of pole members that support the upper and lower ends of the screen by a hanger rail on the ceiling and a guide rail on the floor. Thus, since it has a structure like a large-scale curtain, there is no substantial restriction on the width of the frontage that can be installed, and it can be easily attached to an existing building. In addition, since the weight of the screen and panel is distributed and loaded in the longitudinal direction of the hanger rail arranged on the ceiling side, it can be easily opened and closed manually even in a large scale. Have advantages.

  However, on the other hand, (1) the screen mechanism is weak against wind pressure, and even if it receives a slight amount of wind, large shaking and fluttering occur. It has been pointed out that the folded screen sheet tends to be irregular or messy when opened. (3) Further, when opening the screen mechanism, only a part of the screen sheet in the vicinity of the operation is folded to an extremely high density, and the opening operation of the screen sheet cannot be executed smoothly. Has also been pointed out.

  When the above problem is examined, the problem that the screen mechanism of (1) is weak against wind is that normally a non-breathable continuous material is used as the material of the screen sheet, and that the screen sheet is vertically Although a minimum tension force due to the weight of the sheet itself is applied, the screen sheet has a structure in which no tension force is applied at all in the left-right direction, and thus is fundamentally strongly influenced by wind pressure. In addition, the problem of the problem of the folded state of the screen sheet in (2) is that the operating force when opening the screen mechanism is absorbed by the screen sheet, and is transmitted evenly from one end side to the other end side of the screen mechanism. Because there is no. The problem that the opening operation of the screen sheet of (3) lacks smoothness is that the runners supporting the part corresponding to the screen sheet partially folded at a high density approach each other excessively and interfere with each other in the hanger rail. It depends.

    In addition, although the proposal shown in the said patent document 3 is an applicant's own prior proposal of this application, these problems were actually felt also in this prior proposal. In this prior plan, for the problem (1), the slack remains even when the screen sheet is stretched, and for the problem (2), the screen sheet (blocking curtain) clearly shows in advance. Although the folding shape was improved by giving a fold, the folding shape itself became neat, but the problem that the folding density was partially biased was amplified. In order to cope with the problem (3), the pole member is arranged at every two mountain folds when the screen sheet is viewed from the outside in order to increase the interval between the pole members. The problem of (1), which is weak against the problem, was amplified. In addition, in this prior plan, it is possible to install it in the vicinity of the wall surface of the building to be protected by configuring the folding pile of the screen sheet so as to protrude only on the outside in use of the screen mechanism. It was effective.

  In view of the problems in the screen mechanism using the flexible screen sheet, the present invention is based on the premise that the screen sheet can be installed close to a wall surface of a building, etc. It is an object of the present invention to provide a horizontal screen device that can be held down to a smooth and easy opening operation, and that the screen sheet can be folded in a regular and neat state when opened.

    The present invention adopts the following configuration as means for achieving this object.

  The horizontal screen device according to claim 1 of the present invention is a horizontal hanger rail installed on the ceiling side in a horizontal posture, a plurality of runners loaded on the hanger rail so as to run freely, and installed on the floor side in a horizontal posture corresponding to the hanger rail. A guide rail, a plurality of pole members whose upper ends are attached to the runner of the hanger rail and whose lower ends are slidably guided by the guide rails, and a flexible screen sheet stretched between the plurality of pole members. The screen sheet is folded into a corrugated shape by running a plurality of pole members in a direction that narrows the interval between them, and the screen sheet is developed by running the plurality of pole members in a direction that increases the interval between each other. In the horizontal screen device that enables the double-opening or single-opening opening / closing operation, The roll member is disposed corresponding to each valley fold of the screen sheet folded into a corrugated shape when the horizontal screen device is observed from the outside in use, and the valley fold of the screen sheet includes at least A pair of left and right elastic plates are attached to the screen sheet by using a pole member as a fulcrum at a ratio of one location per two valley folds, and this elastic plate is used when the screen sheet is operated in the unfolded state. By being deformed together with the screen sheet, the screen sheet is biased in a direction to return to the folded state.

  The plurality of pole members in the horizontal screen device according to the above configuration are arranged corresponding to the respective valley folds of the screen sheet folded into a corrugated shape. That is, since all the valley folds are connected to the pole member, the valley folds are expanded by being pushed by the wind pressure, and the phenomenon that the entire screen sheet is greatly shaken or fluttered is prevented. Further, as a result of the pole member being located in the valley fold portion of the screen sheet when the horizontal screen device is observed from the outside in use, the mountain fold portion when the screen sheet is folded is inevitably protected. Since it forms in the form which protrudes toward the outer side of the wall surface etc. of a building, a horizontal screen apparatus can be installed close to the wall surface etc. of a building. In addition, the horizontal screen device having the above-described configuration is similar to a normal horizontal screen device in that the screen sheet is folded into a corrugated shape by moving the plurality of pole members along the hanger rail, or the folded screen sheet is flat. Opening and closing operations can be performed by a simple operation that expands into a shape. A pair of left and right resilient plates are overlapped on the screen sheet of the horizontal screen device at a ratio of one per two valley folds of the folded screen sheet. In addition, at the end in the width direction of the horizontal screen device, since the valley fold of the screen sheet is formed only on the right side or the left side of the pole member, the elastic plate corresponding to this part is Only one piece is arranged on the right or left side of the pole member, but the ratio is the same. The resilient plate that is attached to the screen sheet is deformed along with the screen sheet. This resilient plate is attached with a pole member arranged in the valley fold as a fulcrum, and when the screen sheet is operated to the unfolded state, the screen sheet is folded together by being deformed together with the screen sheet. It is energized in the direction to return. That is, the tension of the elastic plate is applied to the deployed screen sheet over the entire width of the horizontal screen device, and a uniform and neat deployed state is realized. Further, when the screen sheet is folded, the screen sheets are folded evenly at a plurality of locations at the same time by the elastic plates scattered in the width direction of the screen sheet, so there is room for the runners to interfere with each other. It can be folded smoothly and neatly with extremely light operating force.

  The horizontal screen apparatus according to claim 2 of the present invention is characterized in that the resilient plate is attached to a pole member serving as a fulcrum with a play swing range set. .

  The elastic plate in the horizontal screen device having the above configuration does not function as a spring for urging the screen sheet in a folded state in the play swing range. Therefore, it is possible to reduce the required operating force at the start of the closing operation for expanding the screen sheet in the folded state, to suppress the bending fatigue of the elastic plate in the long-term repeated use, and to extend the service life. .

  According to a third aspect of the present invention, the horizontal screen device is characterized in that it is distributed in the vertical direction of the screen sheet along the elastic plate pole member.

    The horizontal screen device having the above configuration has a large distance from the ceiling to the floor. Therefore, even when the vertical length of the screen sheet is long, the elastic plates distributed and arranged in the vertical direction cooperate. Accordingly, it is possible to prevent the occurrence of a problem that the screen sheet is attracted or tilted due to the uneven distribution of the tension only in the upper or lower part of the screen sheet.

    According to a fourth aspect of the present invention, there is provided a horizontal screen device comprising: an upper latch mechanism and a lower latch mechanism in which a pole member disposed at an opening / closing portion of the horizontal screen device among a plurality of pole members maintains a closed state; The upper latch mechanism is composed of a stopper fitting that is fixed to the hanger rail and a latch fitting that is removably loaded into the upper end of the pole member via a compression spring, and the lower latch mechanism is fixed to the guide rail. The stopper bracket and the latch bracket that can be loaded and retracted by manual operation at the lower end of the pole member. The upper latch mechanism and the lower latch mechanism are retracted when the pole member is moved to the shut-off position. And the advancing operation, the latch bracket gets over the stopper bracket and is locked, and the upper latch mechanism is lowered by manual operation. When the latch mechanism of the latch mechanism is retracted and the lower latch mechanism and the latch bracket are unlocked, the lower end side of the pole member moves in the opening direction by the elastic recovery force of the elastic plate that is stuck to the screen sheet. Thus, the upper latch mechanism and the latch fitting are automatically unlocked by the inclined posture.

  In the horizontal screen device having the above-described configuration, the unfolded state of the screen sheet after the closing operation is completed can be maintained by the upper latch mechanism and the lower latch mechanism attached to the pole member of the opening / closing portion. The screen sheet in the closed state (deployed state) is automatically folded by unlocking the lower latch mechanism by manual operation. That is, when the lower latch mechanism is unlocked, the floor side of the screen sheet that is going to return to the folded state by the tension of the elastic plate is pulled in the opening direction, so that the pole member is inclined. At this time, the tension of the resilient plate on the ceiling side is relatively stronger than that on the floor side. Next, the upper latch mechanism is unlocked when the pole member is inclined. Then, the ceiling side of the screen sheet to which tension is strongly applied is pulled more strongly, and the inclined pole member self-runs in the opening direction along the hanger rail while returning to the upright posture.

  In the horizontal screen device of the present invention, the pole member is arranged for each valley fold when the screen sheet is observed from the outside, and is dispersed in a plurality of locations of the screen sheet, and the pole member is used as a fulcrum in the unfolded state. By applying a resilient plate that returns the screen sheet to the folded state, a constant tension can be applied to the unfolded screen sheet at all times. In addition, the unstable phenomenon of fluttering is effectively suppressed, and the screen sheet is biased in the direction of being folded by the elastic plate, so that only a part of the screen sheet is opened during the opening operation. The problem that the smooth opening operation is hindered due to high density folding is also eliminated at the same time In, it can be folded into neat folding appearance of smooth and uniform density across the screen sheet by very light operating force.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. At this time, the outline of the overall configuration of the horizontal screen device will be described first, then the details of each part will be described, and finally the operation of the horizontal screen device will be described.

    The horizontal screen device is a hanger rail 10 installed on the ceiling side U of an arbitrary building to be installed, a guide rail 20 installed on the floor side F, runners 12, 12. .. And 40, 40... And a screen sheet 50 stretched between adjacent pole members 30, 40... As main members (FIGS. 1 and 2). Further, elastic plates 52, 52... Are partially attached to the screen sheet 50.

  The hanger rail 10 is a C channel member, and is fixed to the ceiling surface using mounting brackets 11, 11,... Arranged at regular intervals (FIGS. 1 and 2). The guide rail 20 is a rail-shaped member in which a guide groove 22 is formed, and is embedded in the floor surface corresponding to the hanger rail 10. On the side surface of the guide rail 20, a large number of protruding pieces 21, 21,... For preventing lifting are arranged (FIG. 2).

  As the pole member, a pole member 30 made of a light alloy extrusion mold material and a pole member 40 made of a light alloy pipe material are used in an alternating arrangement. .. Are suspended in an upright posture by connecting to the connecting bars 13, 13..., And the lower end portion extends into the guide groove of the guide rail 20 (FIGS. 1 and 2).

    The pole member 30 made of a light alloy extruded mold is formed into a complex multi-rib structure in which a plurality of attachments are scheduled to be attached (FIG. 4). Pole members 30, 30... Arranged in the part B (FIG. 1) are respectively attached with cushion rubbers 31, 31... A holder groove UM that opens toward the outer side OS in use is formed continuously in the longitudinal direction of the pole member 30 (FIGS. 4 and 7). The pole members 30, 30... Further include an upper latch mechanism 60 and a lower latch mechanism 70 at the upper end portion and the lower end portion (FIG. 3).

    On the other hand, the pole members 30, 30,. . The opening of the holder groove UM has a cross-sectional shape narrowed by the restraining rib 34, and an urging rib 35 projects from the restraining rib 34 (FIG. 4). Further, a regulating surface 36 that regulates the posture of the screen sheet 50 when folded is formed on the opposite side across the opening.

  The screen sheet 50 in the present embodiment is made of canvas, but a vinyl chloride sheet, a net base sheet, or other flexible sheet material is used depending on the installation location of the horizontal screen device and the type of building to be installed. Can be used.

    The upper and lower end portions of the screen sheet 50 are provided with folded portions 51 and 51 that are partially formed in duplicate (FIGS. 2 and 3). The folded forming portion 51 is not formed by the entire surface adhesion, but is connected in a band shape by the stitching means or the adhesive means only at the portions of the welders 5W, 5W that keep a certain distance in the vertical direction, and the upper and lower welders 5W, 5W are connected to the bag (Fig. 3).

    The screen sheet 50 is not used continuously in the width direction of the horizontal screen device, but is stretched in units of adjacent pole members 30 and 30 with a pole member 40 made of a light alloy pipe material interposed therebetween. The elastic plates 52, 52... Are also attached at the same time when the screen sheet 50 is stretched (FIG. 7B).

    Both ends of the screen sheet 50 having a unit width have a triple structure in which the terminal rod 32 to which the elastic plate 52 is attached is sandwiched from the front and back by the screen sheet 50 formed by folding back. Explaining this in the order of assembly (FIG. 4), one end of the elastic plate 52 is inserted and fixed to the core material 33 formed with a slit corresponding to the thickness of the elastic plate 52, and the core material 33 is similarly formed with a slit. The elastic plate 52 covered with the terminal rod 32 and attached with the terminal rod 32 is assembled in such a manner as to be pressure-bonded so as to be wrapped by the folded portion of the screen sheet 50.

    Both ends of the screen sheet 50 subjected to the terminal treatment as described above are connected to the respective pole members 30, 30... By slidingly inserting the terminal rod 32 into the holder groove UM from the cross-sectional portion of the pole member 30. At this time, the screen sheet 50 is led out from the opening of the holder groove UM. The restraining rib 34 of the pole member 30 functions to restrain the inserted terminal rod 32 so that it cannot escape.

    On the other hand, in the middle portion of the unit screen sheet 50, the pipe-shaped pole members 40, 40 are formed such that a part of the screen sheet 50 is formed in the Ω symbol shape, and the pipe-shaped pole member 40 is wrapped inside. (Fig. 7). Therefore, a valley fold V is formed in this portion as observed from the outside OS. When the unit width of the screen sheet 50 handled as one unit is narrow, the pipe-shaped pole member 40 can be omitted.

    Since the posture of the unloaded elastic plates 52, 52... In which no tension is applied to the screen sheet 50 is regulated by the restraining ribs 34 and the regulating surfaces 36 located on both sides of the opening of the holder groove UM, In the play swing range D3 determined by the opening of the restraining rib 34 and the restricting surface 36, the posture is always controlled so as to face the outer OS in use of the horizontal screen device. Therefore, the screen sheet 50 forms a valley fold V in this portion by the pair of left and right resilient plates 52, 52 attached to the pole member 30 (FIG. 7B).

    In the horizontal screen device of the present invention, the pole members 30, 40... Are arranged corresponding to all the valley folds V, V... Of the screen sheet 50 when observed from the outside OS. Are formed in a direction projecting to the outer side OS of the horizontal screen device. In addition, about the pole member 30 arrange | positioned at the opening-and-closing part A and B, since the screen sheet | seat 50 is connected only to one side, it is natural that the valley fold part V is not formed completely.

    The resilient plate 52 in the present embodiment is made of a rectangular resin plate (FIG. 5). The resilient plate 52 is used for the purpose of utilizing an appropriate repulsive force, and is not limited in material, but is preferably made of PP or PE having high resistance to bending fatigue. The resilient plate 52 is provided with a V-shaped groove 5V for facilitating the bending operation along the terminal rod 32. The resilient plate 52 is V-shaped in a state where the terminal rod 32 is fixed. Oscillation can be performed about the groove 5V.

Further, the elastic plates 52, 52... Do not extend over the entire vertical length of the screen sheet 50, but are distributed in correspondence with the upper and lower folded forming portions 51, 51 of the screen sheet 50. However, when the elastic plate 52 having a weak repulsive force is used, the elastic plate 52 may be provided at two or more locations or over the entire top and bottom of the screen sheet 50.

  The upper latch mechanism 60 of each pole member 30 disposed in the single-opening opening / closing part A and the double-opening opening / closing part B (FIGS. 1 and 3) includes a stopper fitting 61 fixed to the hanger rail 10 on the ceiling U, a pole The upper end of the member 30 is composed of a latch fitting 62 that can be inserted and retracted via a compression spring 63 (FIG. 3). The compression spring 63 biases the latch fitting 62 in a direction that always protrudes.

    The lower latch mechanism 70 includes a stopper fitting 71 that is fixed to the guide rail 20 on the floor side F, and a latch fitting 72 that is removably loaded into the lower end portion of the pole member by manual operation. The latch fitting 72 is connected to an operation knob 73 disposed in an intermediate portion of the pole member 30 (FIG. 4), and moves forward or backward by manually operating the operation knob 72 in the vertical direction. The latch fitting 72 of the lower latch mechanism 70 is urged in a direction that always protrudes by its own weight.

  The upper latch mechanism 60 and the lower latch mechanism 70 are automatically locked without requiring another operation by running the pole member 30 along the hanger rail 10 in the wall surface W, that is, in the closing direction F2. In this locking operation, the sloped portions of the upper and lower latch fittings 62 and 72 collide with the stopper fittings 61 and 71, and the stopper fittings 61 and 71 are generated while generating a component force that pushes the latch fittings 62 and 72 into the pole member 30. This is realized by a mechanism in which the latch fittings 62 and 72 are returned by the end of the slope (the state shown in FIG. 3).

  The resilient plate 52 attached to the screen sheet 50 necessarily behaves together with the screen sheet 50 (FIG. 4). As a result, when the pole member 30 is operated in the closing direction F2 and the posture of the screen sheet 50 is changed in the deployment direction D2, the intermediate portion of the resilient plate 52 is pushed and bent by the urging rib 35 (FIG. 2). (Dotted line), a repulsive force is generated on the resilient plate 52 to return the screen sheet 50 in the folding direction D1, and this repulsive force causes the screen sheet 50 to travel the pole member 30 in the opening direction F1. It will be added as the tension of the direction to try. The length of the resilient plate 52 needs to be set to a length that is less than ½ of the interval between the adjacent pole members 30 and 40 (FIGS. 1 and 7). This is because a normal mountain fold M is not formed when the ratio exceeds 1/2.

  In the horizontal screen device having the above-described configuration, in the closed state, a force for changing the state of the screen sheet 50 in the folding direction D1 by the elastic plate 52 always acts, and as a result, the screen sheet 50 Since the force which tries to make the pole members 30 and 40 adjacent to each other approach, in other words, the tension which makes the pole member 30 run in the opening direction F1 is added (FIG. 7A), the conventional product Therefore, it is difficult to be influenced by the wind, and therefore, the neat hanging posture of the screen sheet 50 is maintained extremely stably.

  Further, the horizontal screen device in the closed state is configured to be automatically folded to a certain range when the lower latch mechanism 70 is released by setting the repulsive force of the resilient plate 52 to be strong. Can do. That is, when the operation knob 73 is operated to release the lower latch mechanism 70, the pole member 30 swings the lower end portion around the runner 12 at the upper end portion by the tension in the opening direction F1 applied to the screen sheet 50. (Fig. 6).

  When the pole member 30 tilts around the runner 12, the latch fitting 62 that is engaged with the stopper fitting 61 of the upper latch mechanism 60 also swings in an arc around the runner 12, and when the tilt exceeds a certain limit, The engagement between the stopper fitting 61 and the latch fitting 62 is released (the state shown in FIG. 6). Due to the unlocking of the upper latch mechanism 60 and the lower latch mechanism 70, there is no force that opposes the tension in the opening direction F <b> 1, and a plurality of resilient plates 52 attached to the pole member 30 are provided at a plurality of locations on the screen sheet 50. In FIG. 7, the screen sheet 50 is changed in posture in the folding direction D1, and the screen sheet 50 is automatically and equally folded (FIG. 7B).

  Needless to say, the artificial opening operation of the screen sheet 50 can be facilitated smoothly and easily even when the elastic plate 52 is not automatically folded only by the repulsive force of the elastic plate 52. At this time, there is no problem that only the opening operation portion of the screen sheet 50 is folded at high density, which is very convenient. Further, since all the folded portions M, M... Of the screen sheet 50 when folded are formed so as to protrude to the outer side OS of the horizontal screen device, they are brought close to the wall surface W1 of the building that is symmetrical to the protection. There is also an advantage that it can be installed in a small space.
