Description

  The present invention relates to an integrated roll screen unit that opens and closes an opening of a wall surface.

  In facilities requiring cleanliness, such as electronic equipment factories and food factories, roll screens are often used to protect against dust and insects. For example, when delivering a conveyed product inside or outside a clean room, an opening for delivering the conveyed product is provided on the wall surface of the clean room, and a roll screen is attached to the opening.

  As such a roll screen, a winding shaft rotatably supported in the screen storage box, a screen having one end locked to the winding shaft and a weight bar connected to the other end, and left and right sides of the screen Left and right inner rails that hold the fasteners provided along the edges slidably up and down, a pair of left and right guide rails that accommodate the inner rails, and the left and right inner rails to the left and right sides of the guide rails Generally, an elastic member that biases in the direction is used (for example, Patent Document 1).

  In this roll screen, the left and right inner rails hold the fasteners provided on the side edges of the screen so that they can be slid up and down. It is suitable for dustproofing and insectproofing. In addition, since the left and right inner rails are urged outward in the left and right direction by the elastic member, a horizontal tension is applied to the screen, and sagging hardly occurs.

  By the way, when the roll screen is attached to the wall surface, the screen storage box 40 and the pair of left and right guide rails 41 shown in FIG. 7 are transported to the site as separate members and attached to the wall surface in the following order.

  First, the screen storage box 40 is attached to the upper edge portion 44 of the opening 43 of the wall surface 42 with the winding shaft removed. At this time, the screen storage box 40 is horizontally arranged so that the left and right heights are aligned, and is equally arranged on the left and right with respect to the center of the opening 43 of the wall surface 42.

  Next, the guide rail 41 is attached to the left and right side edge portions 45 of the opening 43 of the wall surface 42. At this time, the guide rail 41 is perpendicular to the screen storage box 40, and the left and right guide rails 41 are parallel to each other. Thereafter, an inner rail (not shown) and an elastic member that urges the inner rail are inserted into the left and right guide rails 41. Subsequently, the winding shaft of the screen 46 is incorporated in the screen storage box 40, and the fasteners on the left and right side edges of the screen 46 fed out from the winding shaft are inserted into the inner rail.

  Finally, the screen 46 is moved up and down to check whether the screen storage box 40 and the guide rail 41 are misaligned. That is, the center of the screen 46 is shifted from the center of the left and right guide rails 41, the left and right guide rails 41 are not parallel, or the guide rails 41 are perpendicular to the winding shaft in the screen storage box 40. Otherwise, since the magnitude of the force of the elastic member acting on the left and right inner rails is different between the left and right, the screen 46 is wrinkled or the screen 46 is wound around the winding shaft at an angle. When there is such an attachment error, the attachment position is adjusted using a shim or a slot.

  Conventionally, the roll screen is attached as described above. However, it is not easy to attach the screen storage box 40 and the guide rail 41 in the field so that the positional relationship is accurate, and the screen once attached. The operation of adjusting the positions of the storage box 40 and the guide rail 41 is complicated.

  The problem to be solved by the present invention is to improve the installation workability of the roll screen in the field.

  In order to solve the above problems, in the present invention, a winding shaft rotatably supported, a screen having one end locked to the winding shaft and a weight bar connected to the other end, and left and right sides of the screen Left and right inner rails that hold the fastener provided along the side edges of the upper and lower sides, a pair of left and right guide rails that accommodate the inner rails, and left and right inner rails for the guide rails. An elastic member that urges the left and right outwards; a rectangular fixed frame in which an upper frame and a lower frame are connected by a pair of left and right side frames; the winding shaft is attached to the upper frame; and the left and right side frames An integrated roll screen unit having the guide rails attached thereto is provided.

  In this integrated roll screen unit, since the screen winding shaft and guide rail are attached to a rectangular fixed frame in advance, the roll screen mounting work is completed simply by fixing the fixed frame to the wall surface. There is no misalignment of the winding shaft or guide rail. Therefore, installation work on site is extremely easy.

  The fixed frame includes an upper horizontal plate extending left and right, an upper wall fixed plate formed by bending upward along the front edge of the upper horizontal plate, and a downward direction along the rear edge of the upper horizontal plate. The lower frame is composed of a lower horizontal plate extending left and right and a lower wall surface fixing plate formed by bending downward along the front edge of the lower horizontal plate. The side frame extends vertically and is opposed to the left and right sides, the side wall surface fixing plate formed by bending the left and right outwards along the front edge of each side plate, and the rear edge of each side plate It consists of a guide rail mounting plate formed by bending inwardly in the left and right direction, connecting the left and right ends of the upper horizontal plate to the upper end of the side plate, and the left and right ends of the upper wall fixing plate to the upper end of the side wall fixing plate. The left and right ends of the lower horizontal plate are connected to the lower ends of the side plates, and the lower wall surface is fixed. Preferably the left and right ends of the plate to adopt those bonded to the lower end of the side wall fixing plate.

  The fixing frame is fitted to the wall surface by fitting into the opening of the wall surface and fixing the upper wall surface fixing plate, the lower wall surface fixing plate, and the left and right side wall surface fixing plates to the peripheral edge portion of the wall surface opening with screws or the like. At this time, since the take-up shaft mounting plate and the guide rail mounting plate are disposed behind the wall surface, the take-up shaft and the guide rail hardly protrude forward from the wall surface, and the take-up shaft and the guide rail are directly attached to the wall surface. Space-saving compared to the case of mounting.

  In addition, the fixed frame has both the left and right ends of the upper horizontal plate connected to the upper end of the side plate, and the left and right ends of the upper wall surface fixed plate are connected to the upper end of the side wall fixed plate. The rigidity of the corner part is extremely high. Similarly, the left and right ends of the lower horizontal plate are connected to the lower end of the side plate, and the left and right ends of the lower wall surface fixing plate are connected to the lower end of the side wall surface fixing plate. Very high rigidity. Therefore, when the integrated roll screen unit is shipped and transported to the site, the fixed frame can be reliably prevented from being deformed and causing a dimensional error.

  Furthermore, the rigidity of the fixed frame can be further increased by connecting the left and right ends of the take-up shaft mounting plate to the guide rail mounting plate.

  In addition, if the width of the side plate is formed so as to be equal to or wider than the width of the guide rail, the guide rail does not protrude forward from the side wall surface fixing plate, so that the integrated roll screen unit is placed on the wall surface. The amount of protrusion from the wall surface when attached can be minimized, and it is extremely space-saving.

  In the integrated roll screen unit of the present invention, since the screen winding shaft and the guide rail are previously attached to a rectangular fixed frame, the roll screen mounting work is completed simply by fixing the fixed frame to the wall surface. However, there is no displacement of the winding shaft or guide rail. Therefore, installation work on site is extremely easy.

The guide groove 22 has an opening width through which the fastener 21 cannot pass, and is held so as to be slidable up and down in a state in which the fastener 21 is prevented from coming off.

  The inner rail 20 is urged outward in the lateral direction with respect to the guide rail 3 by a rubber elastic member 24 incorporated between the inward protrusion 23 formed at the opening of the guide rail 3 and the inner rail 20. Thus, a tension in the width direction is applied to the screen 2. By holding the fastener 21 so as to be slidable by the inner rail 20, it is difficult to form a gap on the left and right when the screen 2 is closed, and the internal and external airtightness is effectively maintained.

  The fixed frame 4 is formed of a metal plate such as a stainless steel plate, and has a square shape in which an upper frame 25 and a lower frame 26 are connected by a pair of left and right side frames 27 as shown in FIG.
