Description

  The present invention relates to a folding horizontal pulling shutter that can move smoothly along an upper rail having a curved portion.

  A horizontal shutter is formed by connecting a plurality of vertically long panels. By providing joint pieces on both side ends of the panel and connecting the joint pieces to each other, each panel can be bent and folded. Therefore, if this horizontal shutter is attached to the frontage, the frontage can be opened and closed by the horizontal shutter. That is, a horizontal shutter configured by connecting a plurality of panels is stretched by being pulled, and each panel is folded and stored in one side of the frontage by pushing a tip (a pull handle).

  There are various uses for the horizontal shutter, and it is used for the front entrance of a store, the reception counter of a hospital, the entrance of a garage, and the like. By the way, the horizontal shutter is configured by connecting a plurality of panels so that they can be folded via a joint, and a suspension wheel is attached to the upper end of the main joint, and a slider is provided at the lower end to protrude downward. . Therefore, the suspension wheel travels on an upper rail extending along the upper end of the frontage, and the slider is loosely fitted on the lower rail along the lower end of the frontage.

  Therefore, the horizontal shutter is suspended on the upper rail via a suspension wheel, and the slider is loosely fitted in a guide groove provided on the lower rail, so that the horizontal shutter moves along the upper rail and the lower rail. The opening can be opened and closed. Here, when the horizontal pulling shutter is moved, the main joint moves along the upper rail and the lower rail, but the secondary joint provided between the main joints protrudes from the upper rail and the lower rail during the folding operation.

  By the way, the horizontal pulling shutter not only moves on a straight line but also may be bent and opened and closed. In such a case, the upper rail and the lower rail have curved portions curved with a predetermined radius of curvature. Yes. Since the upper end portion of the panel is inserted only into the upper rail, the curvature radius R and the panel width of the curved portion are restricted to pass through the curved portion, and the curvature radius R decreases and the curvature increases when the panel width increases. You will not be able to pass through the department.

The “curved orbit structure of the folding horizontal shutter” according to No. 2-4234 is a utility model previously acquired by the patent applicant, and “the doors on the narrow trajectory W ₁ of the Kamoi frame A and the sill frame B” In the folding-type horizontal pulling shutter in which the upper and lower ends of D _{1 to DN} are inserted and guided to move straight, the curved track W ₂ of the corner portion has the narrow track width and the width of the horizontal shutter shutter wheel S. The narrow track W ₁ that is curved with the same curvature as the hanger rail R is provided with an enlarged track W ₂ that is bent and curved, and at least the joint material J ₂ that is not supported by the suspension vehicle S is formed in the track radial direction by the curved track W _2. To give play to. "

That is, the upper rail width is widened at the curved portion so that the panel passes. However, the slider protrudes from the lower end of the main joint and loosely fits in the guide groove formed in the lower rail to guide the lower end of the horizontal shutter, but if there is no lower rail, the panel passes through the curved part The panel will fall inward when pulled inward. As a result, when the panel passes through the curved portion, the suspension wheel is not easily operated by being caught by the upper rail, and this tendency becomes remarkable particularly when the panel width is large and heavy.
"Curved orbit structure of foldable horizontal shutter" related to No.2-4234

  As described above, the horizontal pulling shutter having the curved portion has the above-described problems. The problem to be solved by the present invention is this problem, and provides a horizontal shutter device that can smoothly pass through a curved portion even if it is a heavy panel without a lower rail and having a large panel width.

  The horizontal shutter according to the present invention has a structure in which a plurality of panels are connected so as to be foldable via a joint, and a suspension car is attached to the upper end of the main joint, and the suspension car can travel on the upper rail. I can do it. When a secondary joint exists between the main joints and the lateral shutter is folded, the secondary joint can protrude from the upper rail, and the basic structure as the lateral shutter is common.

  And in this invention, a lower rail is not installed along the side, and the slider fitted to a lower rail for that purpose does not exist in the main joint lower end. However, for example, a lock knob for fixing the lower end of the main joint is provided as positioning means when the lateral shutter is extended to close the frontage. Here, the specific structure of the suspension wheel and the specific structures of the main joint and the secondary joint are not limited. And the guide piece which restrains a panel is deleted inside the curved part of the upper rail, However, The guide member is attached to the both ends inner side of the deleted curved part.

  On the other hand, even when the panel falls inward when passing through the curved portion, the outer periphery is rounded so that the roller of the suspension wheel does not come into contact with the upper rail and bend. In addition, an operating shaft is provided between the upper end of the main joint and the suspension wheel so that the suspension wheel does not tilt even when the panel falls inward.

  The lateral pulling shutter of the present invention can be opened and closed by suspending and moving on the upper rail, but since there is no lower rail, there is no guide groove in which the slider loosely fits on the floor surface. The floor is refreshing. Therefore, floor dust does not enter the guide groove, which is convenient when cleaning the floor.

  And because there is no lower rail, the lower end of the panel is in a free state, and when it passes through the curved part of the upper rail, it tries to fall inside, but the guide members are attached to both inner ends of the curved part. , Can prevent the panel from falling down. However, since the guide member is only at both ends of the curved portion and there is no guide member at the center portion, the panel can smoothly pass through the curved portion without falling down. A guide piece is provided inside the curved portion to restrain the upper end of the panel, but the tilt of the panel can be suppressed by reducing the notch area. Can smoothly open and close through the curved part.

  On the other hand, in order to suspend and open the horizontal shutter, the outer periphery of the wheel of the suspension vehicle traveling on the upper rail may be rounded. For this reason, even if the panel is inclined inward when passing through the curved portion, the roller of the suspension car is not caught by the upper rail and twisted. Further, if an operating shaft is provided between the main joint to which the suspension wheel is attached, even if the panel passes through the curved portion while being inclined, the curved portion can be smoothly moved without being inclined. Can pass.

On the other hand, if the handle 5 of the folded horizontal shutter 1 is pulled, the suspension wheels 6, 6... Travel along the upper rail 2 and the secondary joints 4b, 4b. It will fit.

  And the horizontal shutter 1 of the present invention does not have a lower rail (floor rail), and for this reason, a slider is not provided at the lower ends of the main joints 4a, 4a. Therefore, in order to fix the lower ends of the main joints 4a, 4a... To the floor surface 7 with the horizontal shutter 1 extended and the front opening closed, the lower ends of the main joints 4a, 4a. Knobs 8.8... Are attached, and the lock knobs 8, 8.

  2A and 2B show the curved portion 14 of the upper rail 2. FIG. 2A shows a case where the horizontal shutter 1 is accommodated, and FIG. 2B shows a case where the horizontal shutter 1 is not accommodated in the curved portion 14. FIG. . 3 shows a cross section of the upper rail 2 in which the suspension wheel 6 is accommodated. FIG. 3 (a) is an enlarged view of the BB cross section of FIG. 2, and FIG. 3 (b) is an enlarged cross section of the CC cross section of FIG. Represents. The suspension wheel 6 has rollers 9 and 9 on both sides, and can roll on rail pieces 10 and 10 formed on the upper rail 2.

  Small protrusions 11 and 11 are formed on the rail pieces 10 and 10 so that the suspension wheel 6 does not move to one side, and guide pieces 12 and 12 are provided below the rail pieces 10 and 10. The rail pieces 10, 10 and the guide pieces 12, 12 extend horizontally inward from the side walls 13, 13 of the upper rail 2, and the guide pieces 12, 12 are the upper ends of the panels 3, 3. Can be restrained so as not to shift laterally.

  By the way, as shown in FIG. 3B, the inner guide piece 12 is omitted from the bending portion 14. If the guide piece 12 is provided inside the bending portion 14, the panels 3, 3... Having a predetermined width cannot hit the guide piece 12 and pass through the bending portion 14. However, by not providing the guide piece 12 on the inner side, a space 15 is formed between each of the panels 3, 3... And the inner side wall 13. The panels 3, 3... Move inward to cause backlash.

  The present invention eliminates the inner guide piece 12, but the upper rail can suppress the backlash of the panels 3, 3. It has a structure. FIG. 2B shows the curved portion 14 of the upper rail 2 in a state where the horizontal shutter is not accommodated, and guide members 16 are attached to both ends of the curved portion 14. The guide member 16 is provided at the same position as the guide piece 12, and the shape thereof is a right-angled triangle having an inclined central side, so that the panel 3 moves and easily advances from the curved portion 14 to the straight portion 17. However, the specific shape of the guide member 16 is not limited to the right-angled triangle, and may be any shape as long as the upper end portion of the panel is guided and can be smoothly moved from the curved portion 14 to the linear portion 17.

  Of course, the guide member 16 may be removed so that the inclined guide members 16 remain at both ends of the inner guide piece 12 without being attached to the inner side wall 13 of the upper rail 2. By the way, the length of the guide member 16 is set to a dimension that allows the panels 3, 3... To pass through the curved portion 14 and to prevent rattling, according to the panel width of the horizontal shutter.

  FIG. 4A represents the curved portion 14 of the upper rail 2 that does not accommodate the horizontal shutter 1, and the black portion in FIG. 4 represents an area from which the inner guide piece 12 has been deleted. Therefore, when the upper end of the horizontal shutter 1 is accommodated in the upper rail 2 in this state, a space that can be rattled remains. Therefore, as shown in FIG. 4B, guide members 16 are provided at both inner ends of the bending portion 14.

  By providing the guide members 16, 16 at both ends of the bending portion 14, the internal space 15 is reduced and the backlash of the panels 3, 3 is suppressed. The lengths of the guide members 16 and 16 are set in accordance with the width of the panel 3, and are set to dimensions that can minimize the backlash. Three panels 3 a, 3 b, 3 c are located in the curved portion shown in FIG. 4, and the panels 3 a and 3 c are restrained by the guide members 16, 16. Thus, among the three panels 3a, 3b, 3c positioned in the curved portion 14, the central panels 3b that are connected to each other when the panels 3a, 3c on both sides are constrained by the guide members 16, 16 also. Restraint prevents backlash.

  FIG. 5 shows a case where the outer periphery of the rollers 9 of the suspension wheel 6 is rounded. By providing the guide members 16, 16 at both ends of the bending portion 14, the upper end portion of the panel is restrained and the panel 3 is prevented from falling inward. However, when the panel 3 falls down, the outer periphery of the rollers 9 and 9 has a rounded shape as shown in FIG. That is, the rollers 9 and 9 are not twisted and the movement of the panel 3 does not become difficult even if the tilting is somewhat larger than in the case of the rollers 9 and 9 of the suspension wheel 6 shown in FIG.
