Description

Specification

Horizontal opening shirt

The present invention relates to a horizontally opening shutter having a shutter body configured by extending a vertically elongated unit panel so as to be able to bend left and right, and pulling out or pulling out the shutter body along a suspension rail having a corner portion. This is a drawer-type horizontally-open shutter that opens and closes by pushing it in. In particular, it refers to the running guide of the shutter body, the connection structure of the unit panels, the guide structure at the corner of the suspension wheel for hanging the leather panel, and the automatic opening and closing device of the shutter body. Background art

Shutters are classified according to their opening and closing direction into vertical and horizontal opening types, and are classified into folding, drawer-type and winding-up types according to their opening and closing structures. The vertical opening here means moving the shutter up and down to open and close, and the horizontal opening means moving the shutter left and right to open and close. The foldable type is a zigzag folding panel that forms one side of the shirt, and the shutter is opened.The pullout type is a type with a rail that has a corner and a shutter body. Opening / closing is performed by running the vehicle, and the retractable type is a unit that winds up a unit panel and opens the shutter. Conventional vertical opening shutters are taller and require heavy opening and closing of the heavy shutter body.It takes a long time to open and close with the prime mover, especially when passing through the opening when it is half open. Great feeling. Also, since the unit panel is horizontally long, dust tends to be attached to its connecting part, and the weight of the shutter body acts on the connecting part of the unit panel, so that the connecting part has a rugged structure and the shutter can be opened and closed. At times, a large amount of force is applied to the link, causing it to bend, resulting in loud opening and closing noise. Further shang

Mistake (^ n ^! J2c) Since power is required to open the main unit, children with weak power cannot open it, and when it is powered by electric power, it cannot be opened when the power is turned off, and it takes time to open. It is an obstacle to evacuation in an emergency.

On the other hand, in the case of a wide-open shutter, the weight of the shutter is supported by rails, so the unit panel that constitutes the shutter is supported by suspension wheels, so even a large and sturdy shutter can be manually opened and closed. And noise at the time of opening and closing can be reduced. Of the folding shutters, folding and rewinding shutters require a thicker unit panel to increase the strength of the shutter, which increases the occupied space in the folded or wound state. The opening area becomes smaller. In particular, the winding type does not fit well in the wound state, and different operations are required between winding and unwinding. On the other hand, in the case of the foldable type, it is necessary to bend the connecting part between the panels by 180 degrees when folding, so that the panel is made thicker to have strength, and the connecting part is also given sufficient strength. In such a case, the structure of the connecting portion becomes complicated, and the number of parts increases, resulting in a very high cost.

The drawer-type horizontally-opening shutter is convenient because it does not have such disadvantages.In the drawer-type horizontally-opening shutter, a plurality of vertically elongated unit panels are connected to the left and right so that they can bend freely around the ¾ί axis. It is known that a shutter main body is formed by moving the shutter main body along a horizontal suspension rail to open and close the shutter main body.

In addition, in the conventional horizontal opening shutter, the shutter body is moved in the direction of the side wall of the room when it is normally opened, so a 90 'corner is formed on the suspension rail. Become. The unit panels constituting the main body are supported by the suspension wheels to support the weight, and the direction of the panel surface is defined by the side wheels.The side wheels define the direction of the surface of each unit panel, In addition, in order to prevent a gap from being generated between adjacent unit panels, the unit panels need to be positioned at both left and right ends. The position of the suspension wheel is not particularly strictly defined, but is preferably provided at the center of gravity of each unit panel, that is, at the center of the upper side. These suspension wheels are usually mounted rotatably about an axis perpendicular to the plane of the panel.

Replacement form (Rule 26) Further, as a conventional automatic opening / closing device for a horizontally opening shutter, a structure in which a timing belt and a chain are arranged along a suspension rail is often proposed. While these structures are reasonably reasonable, buildings where shutters are to be installed often have dimensional errors that are much larger than the tolerances allowed by mechanical equipment, so long spans It is difficult to accurately set the positional relationship between the suspension rail and the timing belt chain over a long period of time, and it takes time to complete the construction. In addition, belts and tunes grow, and maintenance is troublesome. As another structure of the automatic opening / closing device, the unit panel 1 is formed into a U-shaped cross section in plan view to form rack teeth by the unit panel itself, and the binion is provided with teeth to be engaged with the recess on the back side of each unit panel. There is one that opens and closes the shutter body by reversing around the vertical axis (Japanese Utility Model Publication No. 7055555).

The present invention is a drawer-type lateral opening, which is light and easy to open and close, has a large opening area, has a simple structure, has sufficient strength to endure outdoor use, has good durability, and has a good appearance. The first object of the present invention is to provide a shutter. In particular, according to the present invention, there is no gap in a panel connecting portion at the time of opening and closing as well as at the time of closing, and the panel connecting portion has airtightness. The primary objective is to obtain technical means that can make the surface of the shirts without unevenness when closed and simplify the structure of the hanging parts and connecting parts of each panel. I have.

A second object of the present invention is to minimize the operating force required for opening and closing the shutter in a conventional drawer-type horizontally opening shutter. The resistance of the conventional drawer type horizontal opening shutter when opening and closing the shutter body mainly occurs at the corners of the suspension rails.If the radius of curvature of the suspension rails at the corners is reduced, a large force is required for opening and closing operations. Eventually, it becomes difficult to open and close the shutter body by hand. On the other hand, if the radius of curvature of the corner is increased, the shirt body can be opened and closed with a small force, but the space efficiency of the room in the corner deteriorates. Since a large radius is formed, the appearance is also unfavorable. So in the corner

Replacement form (Rule 26) There is a demand for making the radius of curvature of the rails as small as possible and reducing the running resistance when passing through the corners. A second object of the present invention is to obtain a technical means satisfying the above requirements.

Further, a third object of the present invention is to obtain an inexpensive side-opening shutter with an automatic opening / closing device, which has low noise at the time of opening / closing and can be manually opened / closed with a small force at the time of power failure or the like.

It is characterized by being larger than the fitting length of the pivot pair.

Hereinafter, the operation of the invention described in claims 1 to 4 will be described. In the structure according to claim 1, the adjacent unit panels 1, 1 are connected to each other so as to bend around the support shaft 4 of the side wheel 13 that defines the left-right position of the panel, Since the lateral position of the side wheel 13 (with respect to the suspension rail 18) is defined by the suspension rail 18, no matter how the suspension rail 18 is bent in the horizontal plane, the bent portion Therefore, there is no deviation between the vertical sides 2 and 3 of the adjacent unit panels, and one of the vertical sides 2 and 3 has a convex cross section of a substantially semicircular arc centered on the support rib 4. Accordingly, a structure in which there is no gap between the adjacent unit panels 1 and 1 even during the refraction can be obtained in combination with the fact that the displacement does not occur during the refraction.

In the structure according to claim 2, the other side 3 of the adjacent side is a concave section of a substantially semicircular arc, and is configured to fit with the vertical side 2 of the convex section, so that Even when an external force is applied, it is possible to prevent only the relevant unit panel from bending, and the resistance to the external force is increased, and even when an external force is applied, no steepness is generated at the connection portion of the unit panel. Can be structured. By providing a seal lip at the bottom of the longitudinal side 3 having a concave cross section, the airtightness of the unit panel connecting portion can be maintained.

Replacement paper (reg. Πϋ20 By adopting the structure described in claim 3, the structure of the connecting portion of the horizontal panels of the horizontal opening shutter having the structure described in claims 1 and 2 can be easily manufactured and assembled. Can be structured. In other words, the support shaft 4 that supports the side wheel 13 is powerful, and is also used as the hinge shaft that connects the unit panels to bend freely, and the vertical side 2 of the convex section is fitted under the upper bracket 11 As a result, unit panels 1 can be connected one after another. Each unit panel 1 can have exactly the same structure including the suspension wheels 9 and the side wheels 13 to reduce the manufacturing cost of the unit panel and to replace the unit panel 1 as necessary. By adding them together, shutters of various widths can be easily assembled.

According to the structure described in claim 4, adjacent unit panels can be easily attached to and detached from each other. Therefore, when some unit panels are damaged, it is easy to replace only the relevant unit panel. Since each unit panel 1 can be weighed so that it can be transported by human power, if the structure described in claim 4 is used, no crane etc. is used at the shutter installation site It is possible to assemble the main body of the shutter, and the repair and replacement of the damaged main body does not require a crane vehicle.

The invention according to claims 5 to 9 relates to a guide structure of the shutter body. The guide structure of the horizontal opening shutter described in claim 5 is such that a plurality of vertically elongated unit panels 1 are connected to be able to bend vertically and horizontally around the unit panel 1 and suspended at the upper end of each unit panel. Wheels 9 and side wheels 13 for guiding the direction of the panel surface are provided, and the side wheels 13 are located at the left and right ends of each unit panel 1 and the suspension wheels 9 are located in the middle of the adjacent side wheels. It has a suspension rail 18 that guides the side wheels 13 and a rolling surface 19 that supports the suspension wheels, and the suspension rail 18 is a guide for a horizontal shutter that has a corner 25. When the side wheels 13 pass through the corners 25 of the rails in the creature, the rolling surface of the suspension wheels 9 has concave grooves or ridges 26 along the moving direction of the suspension wheels 9. The corner rails 26 of the brackets are the corners of the suspension rails 18 that guide the side wheels 13. Curvature of radius r, a larger radius of curvature

Replacement paper (Rule 26i It is characterized by having r ₂ and r ₃ .

The invention according to claim 6 is the guide structure for a horizontal opening shutter according to claim 5, wherein the corner rail is a concave groove-shaped corner rail 26, and the corner rail 26 is provided. Has a maximum groove width in a region 32 between both ends 29 and a midpoint 31.

The invention described in claim 7 of the invention is characterized in that, in the guide structure of the horizontal opening shutter according to claim 5, the corner rail is a convex corner rail 26 and the corner rail 2 6 is characterized in that it has a minimum protrusion height in a region 32 between both ends 29 and the middle 31.

The invention according to claim 8 is the guide structure for a horizontally opening shutter according to claim 5, wherein the suspension wheel 9 comprises two wheels arranged in series in close proximity to each other. The bogie supporting the wheels is mounted on the upper end of the unit panel 1 so as to be swingable about a vertical axis.

The invention according to claim 9 is the guide structure for a laterally open shutter according to claims 5, 6, 7, or 8, wherein the distance W between the adjacent side wheels 13 defines the side wheels. The radius of curvature r, at the corner of the rail 18 is not more than twice the root.

The operation of the invention described in claims 5 to 9 will be described below. FIG. 7 is a plan view schematically showing a state where the unit panel 1 passes through the corner 25 of the suspension rail. When the panel passes through the straight part of the rail, the panel moves in the direction of movement of the suspension wheel and there is no slippage between the suspension wheel and the rolling surface. When one of the side wheels 13 and 13 enters the corner 25 of the rail, the unit panel 1 is swung around the trailing wheel remaining on the straight part of the rail, and the moving direction of the suspension wheel 9 is Deviated from the moving direction, the suspension wheel 9 skids. When the unit panel reaches the middle position of the corner, the moving direction of the suspension wheel and the rolling direction match only at that moment, and when the unit panel 1 passes through the corner, the suspension wheel 9 is connected to the corner. A skid occurs in the direction opposite to that of the approach. If the radius of curvature r, of the corner is large, the way the suspension wheel rolls when passing through the corner

Replacement (paper PJi26) The deviation between the heading direction and the moving direction is small, and the suspended wheels roll and skid past the corners. When the suspension wheel 9 rolls, the opening and closing resistance of the shutter does not increase so much even if slight skidding occurs.

When the inventor of the present application observed the behavior of the suspension wheels passing through the corners of various radii, when the radius of curvature r, of the corners became small and the amount of sideslip became large, the suspension wheels 9 rolled over. Regardless of the movement in the movement direction, a phenomenon was observed in which the robot did not transfer at all. When the suspension of the suspension wheels stops, the force required to open and close the shutter suddenly increases, and when the radius of curvature is further reduced, the unit panel 1 reaches the neutral position of the corner. By the way, the phenomenon that the panel was hacked was observed.

The inventions of claims 5 to 9 are based on the above observation results, and provide a concave or convex corner rail 26 on the rolling surface of the suspension wheel at the corner of the rail. Thus, the phenomenon that the suspension wheels do not rotate at the corners is prevented, and the opening and closing resistance of the shutter is reduced. In the case where the corner rail is formed in a concave groove shape, as shown in FIG. 8, the suspension wheel 9 which is slightly oblique to the corner rail 26 comes into contact with the fallen wall portion of the corner rail, and the suspension wheel The suspension wheel 9 is rotated by the reaction of the force trying to ride on the side wall of the corner rail, and is pushed in the skidding direction, so that the suspension wheel 9 is smoothly guided in the moving direction, and the suspension wheel 9 rotates. By moving, the running resistance of the suspension wheel 9 when passing through the corner portion is greatly reduced. Further, the structure in which the convex corner rail 26 is provided on the rolling surface uses the suspension wheel 9 having a guide groove on the peripheral surface to guide the suspension wheel at the corner portion (see FIG. 9). ). Even in this structure, the suspension wheels with guide grooves that come into contact with the corner rails 26 at a deviation angle in plan view are positively driven by the reaction force of the force trying to ride on the ridge. As it is rotated, it is pushed in the skidding direction, and the running resistance is greatly reduced.

As described in FIG. 7, the suspension wheel 9 when passing through the corner portion and the corner

(Replacement paper £ 1026) The deviation from the direction of the corner 26 becomes maximum at a position from the midpoint of the area 32 between both ends of the corner rail and its midpoint. If the corner rail has a groove width and the groove width of the corner rail is constant, when the suspension wheel passes through both ends 29 and the midpoint 31 of the corner rail, the space between the groove and the suspension wheel A play occurs in the groove width direction, and if this play is to be eliminated, a phenomenon occurs in which the suspension wheel cannot fit in the groove in a region between both ends 29 and the middle point 31. The configuration described in claim 6 avoids this phenomenon.The outer diameter side surface 27 and the inner diameter side surface 28 of the concave groove-shaped corner rail 26 are shown in FIG. As described above, this can be realized by forming an arc having a different radius from the center position.

The configuration described in claim 7 avoids the above-mentioned phenomenon when the corner rail 26 is formed as a convex rail. By reducing the height of the convex line, the convex line In the state of being fitted in the guide groove 35 of the first embodiment, it is possible to allow a deviation between the direction of the suspension wheel 9 and the direction of the corner rail 26.

The structure described in claim 8 is a structure in which the suspension wheel 9 is a so-called bogie type structure shown in FIG. 10. In this structure, the suspension wheel 9 is in a direction closer to the tangential direction of the corner rail. As a result, the amount of side slip of the suspension wheel when passing through the corner portion is reduced, and thus the traveling resistance when passing through the corner portion can be further reduced.

The traveling trajectory of the suspension wheel 9 when passing through the corner is a curve having a larger radius of curvature r and a larger radius of curvature at the corner of the rail guiding the side wheels 13, but the curve at the both ends of the unit panel 1 If the distance between the side wheels W (see FIG. 7) and the radius of curvature r at the corner of the rail 26 guiding the side wheels is larger than twice the root (when the corner angle is 90 '), the suspension wheel The center locus is formed in the locus of the corner portion. When the trajectory of the suspension wheel becomes like this, when the suspension wheel 9 is located in the recess at the midpoint, the direction of the force in the shutter opening and closing direction acting from the panel adjacent to the corner panel 1 of the corner portion, and the suspension A large angle difference occurs between the skid direction of the wheel 9 and the skid direction, so that the resistance when passing through the corner increases sharply. The configuration described in claim 5 is

^ * ^; E (Rule 26) As described in claim 5, by defining the relationship between the distance W between the side wheels and the radius of curvature r of the corner of the rail guiding the side wheels, It is possible to prevent the trajectory of the suspension wheel at the corner from having a midpoint depression. In addition, by doing so, the planar shape of the corner rail for guiding the suspension wheel 9 can be approximated to an arc, and the design and processing of the corner rail are facilitated.

Claims 10 and 11 relate to an automatic opening / closing device for a shutter body. The horizontal opening shutter provided with the automatic opening / closing device according to claim 10 includes a suspension rail 18 having a flat L-shape or a U-shape, and a free-running suspension on the suspension rail via a suspension wheel 9. The shutter main body 6 1

1 is formed by connecting a plurality of unit panels 1 that are elongated in the vertical direction to the left and right so that they can bend freely around 4 and 5; each unit panel 1 has side panels 13 on both sides located at the upper end of the panel. In the open shutter guided in the running direction, each unit panel 1 has an upwardly facing rack tooth 55 at the upper end thereof, and is connected to the rack tooth 55 at the linear portion 24 of the suspension rail 18. Pinion 6 2 is arranged, and this pinion 6

An electric motor 67 for driving the motor 7 in the normal and reverse directions is provided. The invention according to claim 11 is the horizontal opening shutter according to claim 10, wherein the rack teeth 55 are in a direction outside the corner portions 25 of the suspension rail 18. 18 and the unit panel 1 are provided so as to be offset from the center.

The operation of the invention described in claims 10 and 11 will be described below. In order for the shutter body to travel along the suspension rails 18, there must be a play space between the two. However, if the unit panel 1 of the shutter body is hung on the suspension rail 18 with the suspension wheel 9, the vertical clearance between the suspension wheel 9 and the suspension rail 18 will be reduced by the weight of the unit panel 1. Can be reduced to zero. The conventional rack-and-vinyl type automatic opening and closing device is designed so that the rack teeth are oriented perpendicular to the plane of the panel and the binions are joined from the side.

Ten

Replacement paper (Rule 26) Due to the structure, the engagement between the rack teeth and the pinion was not constant, generating noise and requiring extra power for opening and closing. In contrast, in the present invention, the rack teeth

Since the pinion 6 3 is engaged from above by providing the pin 5 5 upward, the meshing reaction force is received between the suspension wheel 9 and the suspension rail 18 with no gap, and accordingly, the rack teeth The engagement between 55 and the vinyl 63 is kept constant, so that noise generation is reduced and power transmission efficiency can be increased.

According to the invention described in claim 11, the pinion 63 and the rack teeth 55 are located on the side of the suspension rail 18 so that the bearing of the pinion 63 and its driving motor 67 are suspended. Since the device can be mounted on the upper part of the rail 18, the device can be converted, and accurate positioning accuracy between the rack teeth 55 and the pinion 63 can be easily realized.

The elliptical imaginary line 33 shown in FIG. 8 shows a schematic shape when the suspension wheel 9 is cut at the position of the upper surface of the groove of the corner rail. It is obliquely in contact with sides 27 and 28. In this state, when the suspension wheel 9 is guided to the side surface of the corner rail 26, a lateral pressure for guiding the suspension wheel 9 in the moving direction acts, and the suspension wheel 9 is forcibly rotated.

FIG. 5 also shows the guide structure at the lower end of the unit panel 1 at the corner. In the straight portion, the lower end of the unit panel 1 is guided by fitting the shower 6 fixed to the lower end of each unit panel 1 with the guide 7 provided on the floor surface. In the corner portion 41, a synthetic resin groove block formed by molding the outer side surface 42 and the inner side surface 43 with an arc resembling the locus at both ends and the central portion of the inner and outer surfaces of the housing 6. 4 4 guides show 6. When the vertical panel 1 passes through the groove block 4, the outer sides of both ends of the show 6 are guided by the outer surface 42 of the groove block, and the inner surface of the central portion is the inner surface 4. Guided by 3. The advantage of employing such a groove block 44 is that the lower end of the upper panel 1 can be reliably guided at the corners without generating a large gap between the lower end of the unit panel 1 and the floor surface. What you can do. The lower side of the opening is guided by fitting the guide groove 20 of the show 6 into the convex rail 45. Instead of providing such a concave groove-shaped corner rail at the corner, a ridged rail 26 as shown in FIG. 9 is provided, and a guide is fitted around the suspension wheel 9 with the rail 2 G. In this structure, a groove is provided. Further, as shown in Fig. 10, two wheels are attached to a bracket extending from the outer upper end of the unit panel, and a suspension wheel is attached to a bogie that can swing around a vertical fulcrum pin. By making this wheel lonely with a concave or convex corner rail 26, it is possible to reduce the resistance of the suspension wheel when passing through the corner.

On the upper and lower ends of the vertical side 2 of the convex section of the unit panel 1, an upper vertical hole 16 and a lower vertical hole 17 are provided at the center of the arc, and the upper vertical axis (bin) 4 and the lower vertical axis ( The bin (5) is inserted into the upper vertical hole (16) and the lower vertical hole (17), so that the adjacent vertical sides (2, 3) are connected to be freely refracted. At both ends of the spacer block 51, notches 4 7 4 8 corresponding to the notches 14 of the unit panel are provided. The planting height of the lower vertical axis 5 is shorter than the thickness (vertical dimension) of the spacer block 51, and the downward projection length of the upper vertical axis 4 is the spacer block 51. Longer than the thickness of. A notch 49 is provided at the end of the roller bracket 50 on the side opposite to the wheel so as not to interfere with the adjacent side wheel. With this structure, the unit panel on the back side in Fig. 1 is lifted up by the thickness of the spacer block 51, the lower vertical axis 5 is pulled out from the lower vertical hole 17, and the lower unit panel is slightly lowered and lowered. By pulling out the upper vertical axis 4 from the upper vertical hole 16, the unit panels can be separated from the unit panel in front of the figure, and the unit panels can be sequentially connected in the reverse order. By sequentially connecting the unit panels by such an operation, a shutter main body 61 having a desired width is formed. Notches 4 8 and 49 on the near side in Fig. 1 of the spacer block 51 and the roller bracket 50 lift one unit panel in order to extract the lower longitudinal axis 5 from the lower longitudinal hole 1 Ί. At the time, the unit adjacent to this is provided to avoid drying with the side wheel 13 of the panel, and the notch 4 7 in the back of FIG. It is provided in order to prevent the unit panel to be lifted from drying out with the upper end of the vertical side of the convex section of the unit panel. Also, due to the above structure, the unit panel on the back side in Fig. 11 can move upward along the vertical axes 4 and 5 with a stroke shorter than the planting height of the lower vertical axis 5 with respect to the unit panel on the near side. it can.

At both ends of the protruding portion of the spacer block 51, mating teeth 52, 53 having horizontal teeth are formed. A rack block 54 made of a synthetic resin molded product is fixed to the upper surface of the protruding portion of the roller bracket. When the adjacent unit panels 1 and 1 are aligned with each other, the adjacent

Replacement paper cmm The small ends of the ridges 51 abut each other, and the interlocking teeth 52, 53 engage with each other. A gap 56 corresponding to one tooth of the rack teeth 55 formed on the upper surface is formed between adjacent rack blocks. As shown in Fig. 14, the rack teeth 55 and the mating teeth 52, 53 formed at the edge of the fore edge are located on the outside (outer diameter side) of the corner 57 of the suspension rail 18, as shown in FIG. positioned.

A pinion 63 that opens and closes the shutter main body 61 in accordance with the rack teeth 55 is disposed near the corner 57 of the linear portion 24 having the slope. As shown in Fig. 11, as shown in Fig. 11, a swing frame that can swing up and down around a support 6 5 that intersects the suspension rail 18 at right angles to the base 6 4 fixed on the mounting seat 2 2 of the suspension rail 18 66 is attached, and a binion 63 is fixed to an output shaft 68 of a motor with speed reducer 67 mounted on the swing frame, and faces the rack teeth 55. The driving frame 66 is connected to a panel 69 for urging the driving frame upward and a solenoid 71 for pulling the panel downward. When the solenoid 71 is not energized, the swing frame 66 is moved upward by the biasing force of the spring 69, and the binion 63 is separated from the rack teeth 55. When the automatic opening / closing switch is operated, first, the solenoid 71 is energized to pull down the swing frame 66. Since the support 65 of the swinging frame is at a high position, the pinion 63 moves downward while slightly laterally moving in the traveling direction of the unit panel 1, and engages with the rack teeth 55. Next, the motor is started, the binion 63 rotates, and the shutter body 61 runs.

FIGS. 14 to 16 show a drawer-type horizontally-opening shutter according to the present invention installed in a garage. Since the adjacent vanes can move up and down relative to each other, even when the rail 18 has an up-down inclination, it is possible to run the shirt-down. At this time, the adjacent unit panels are slightly shifted up and down to form a step-like shape. As the shutter body passes through the corner, the interlocking teeth 52, 53 are separated from each other, and the interlocking teeth 52, 53 in the straight section are joined together with the rack teeth 55. Lined up on the line. The upper part of Fig. 14 is the opening 58 of the building, and the left side is the following wall 59 of the building. When the shutter is opened, the shutter body 6 1 is the side wall 5

Replacement form (Rule 26) Pulled in along 9 If the floor of the building 62 (Fig. 15) has a slope for drainage, etc., the straight part 24 of the suspension rail along the fallen wall 59 will have a slope as shown in Fig. 16. .

If the suspension rail 18 where the pinion 6 3 is placed is horizontal, the rack teeth 55 are also in the same horizontal plane, but if the suspension rail 18 has a gradient, there is a step between the adjacent rack teeth. . As described above, in this embodiment, the gap 56 corresponding to one tooth of the rack tooth exists between the adjacent rack blocks 54, and therefore, one tooth at the connection portion with the adjacent rack tooth. There are missing teeth. Due to the presence of the missing teeth, the step between the adjacent rack teeth is connected with a gentle gradient, and the impact and noise when passing through the step can be reduced.

When the unit panel moves to the linear part 24 with a slope, the mating teeth 52, 5 3 at the small end of the Su-sub mouth 51 adjoin the linear part that has entered the linear part first. The unit panel 1 engages with the mating teeth 52 of the panel with a step, preventing the vertical sides 2 and 3 facing each other from slipping, thereby preventing the unit panel 1 from tilting. Therefore, the vertical posture of each unit panel is maintained even after all the unit panels are drawn into the inclined straight section 24. When passing through the corner 25 of the suspension rail, the engaging teeth 52, 53 are separated from each other, so when they pass through the corner and enter a horizontal straight section, they have a relative positional relationship with no steps. Opposing mating teeth 52 and 53 will mesh.

A synthetic resin shoe 6 having a downwardly facing U-shaped groove is fixed to the lower end side of the unit panel 1 so that it is guided by a guide 7 provided on a floor surface 62. This guide 7 can guide the shutter in the direction of movement of the shutter, the direction of the unit panel 1 is defined by the upper side wheel 13 and the structure that prevents the adjacent panels from shifting from each other. It is. Industrial applicability
