Description

The present invention relates to a technical field of a shutter curtain reinforcing device in a building shutter device provided for opening and closing an opening such as an entrance / exit of a building or the like.

Today, a building shutter device is provided at an opening such as an indoor / outdoor entrance / exit of a building or the like so that the shutter curtain is moved up and down by guide rails arranged on the left and right to open and close the opening. Sometimes. And the shutter curtains provided in such architectural shutter devices are directly affected by the weather fluctuations on the outdoor side, and in such weather fluctuations, in the event of bad weather such as typhoons and torrential rains. There is a strong wind that is generated, and it is required that the shutter curtain be able to withstand such a strong wind.
By the way, when the shutter curtain receives a strong wind, the shutter curtain has a problem that the left and right end edges come out of the guide rail due to the central part bending (recessing) indoors and outdoors, so that there is a problem that the left and right ends of the shutter curtain. A windproof hook is provided on the edge portion, and when the shutter curtain bends due to a strong wind, the shutter curtain is locked to a locking portion provided in the guide rail to prevent the shutter curtain from bending. This prevents the shutter curtain from coming out of the guide rail and enhances wind resistance.
Some of the wind-resistant hooks are provided with sufficient wind-resistant performance, but those without the wind-resistant hook or those provided with a large opening can be used by the wind-resistant hook alone to prevent a large typhoon from attacking. Some of them do not have the corresponding wind resistance, so in order to correspond to the shutter device for construction in such a case, reinforcing columns are provided on at least one of the inside and outside of the shutter curtain in the closed posture, and the reinforcing columns are used for strong winds. It has been proposed that a shutter curtain that has been bent in response to the shock and receives the shutter curtain so as to exhibit the necessary wind resistance function (see Patent Documents 1 and 2).

An operating screw 24g is provided on the side surface 24f. Then, by tightening the operating screw 24g in a state where the rod-shaped body 24b moves upward above the floor surface F, the tip of the operating screw 24g comes into contact with the operating screw in a pressing manner, and the vertical movement is restricted. By loosening the operating screw 24g, the vertical movement including the self-weight descent is allowed, and the self-weight descent can be lifted along the elongated hole 24d by grasping the operating body 24e. It has become like.
When the rod-shaped body 24b is lowered by its own weight while the reinforcing column 11 is located at the reinforcing position, the rod-shaped body 24b is fitted into a drop portion 25 described later to support the positioning of the lower end portion of the reinforcing column 11. Although the movement is restricted to the storage position side in the positioning posture, the upper end edge of the rod-shaped body 24b in the state where its own weight is lowered is set to be located below the operation screw 24g. Therefore, with the rod-shaped body 24b in the positioning posture in which its own weight is lowered, the operating screw 24 g is deeply screwed into the support metal fitting 24a so that the tip of the screw overlaps (positions) on the upper side of the rod-shaped body 24b. Therefore, the upward movement of the rod-shaped body 24b to escape from the drop portion 25 is restricted so that the rod-shaped body 24b does not come out of the drop-in portion 25 and the positioning is released.

On the other hand, the drop portion 25 is formed in a state of being embedded in a mounting hole Z drilled in a portion corresponding to the reinforcement position of the floor surface F, and the drop portion 25 is formed by a main body portion 25a, a lid portion 25b, and a lid portion 25b. Although it is configured to include a flange portion 25c, the main body portion 25a has a bottomed square cylinder shape, and a protruding surface portion 25e is further formed on the left and right outer sides of the left and right side surface portions 25d thereof.
On the other hand, the flange portion 25c is attached to the upper end edge of the main body portion 25a, and an opening 25f is formed so that the lid portion 25b can be detachably attached. The edge portion 25g extends to the one protruding surface portion 25e, while the other edge portion 25h extends to the other side surface portion 25d.
Further, the lid portion 25b is set to close (cover) the opening portion 25f in a state where the lid portion 25b is fitted inside the opening portion 25f and is flush with the flange portion 25c. , The auxiliary plate 25i is provided adjacent to the lower side. The auxiliary plate 25i is placed on the notched portions 25j formed on the left and right side surface portions 25d of the main body portion with the left and right both end edges in a state where the opening portion 25f is closed by the lid portion 25b. It is configured to support the main body portion 25a of the 25b.

Further, the lid portion 25b is provided with an operation portion 25k having a concave groove formed on the upper surface thereof, which can be rotated by inserting a negative driver or a peripheral portion of a coin (for example, a 10-yen coin). A locking piece 25 liters is provided at the lower end portion. Then, by rotating the operation portion 25k, the locking piece 25l is fitted into the locking hole 25m formed in the side surface portion 25d of one of the main body portions, and the lock is locked from the locking posture in which the lock is locked in a retaining shape. By coming out of the hole 25m, the lock can be unlocked and the lid 25b can be removed.
In the present embodiment, the lid portion 25b removed in the unlocked state by operating the operation portion 25k has the tip portion of the lid portion 25b and the auxiliary plate 25i protruding from the side surface portion 25d of one of the main body portions. It is configured so that it can be temporarily held by inserting it between the face portion 25e and the surface portion 25e.

As described above, the reinforcing device 8 of the shutter curtain 3 including the reinforcing column 11 in which the present invention is carried out can be assembled together with the newly installed shutter device 1 when it is built in the opening E, but the existing shutter device Even in No. 1, it can be easily assembled as a retrofit, and the assembly procedure (method) will be described below.
When assembling to the existing shutter device 1, the members to be transported to the site and prepared are the constituent members of the reinforcing column 11, the upper rail 9, and the drop portion 25, and among the members transported to the site, First, a rail mounting step of mounting the upper rail 9 on the upper part of the opening E is executed.
Next, the support column assembling step of incorporating the reinforcing column 11 into the upper rail 9 is executed, and the opening end edge portion 9e on the reinforcement position side of the upper rail 9 attached in the rail mounting process is closed by the closing plate 9g. When the product was transported to the site in a detached state, the opening end edge portion 9e was opened by removing the closing plate 9g, and the opening end edge portion 9e was provided at the upper end portion of the reinforcing column 11. By fitting and incorporating the upper roller 15, the step of attaching the reinforcing column 11 to the upper rail 9 is executed. The execution of the support column attachment step of the reinforcing column 11 to the upper rail 9 also includes a step of opening and closing the open end edge portion 9e via the closing plate 9g.

Further, in this case, a drop portion forming step for forming the drop portion 25 on the floor surface F is required, and the position where the drop portion 25 is formed can be accurately specified by the design dimensions on the floor surface F at the site. In this case, the drop-in portion forming process can be executed regardless of the execution of the rail mounting process and the support column assembling process, but in this case, accurate dimensioning work is required to specify the drop-in position. become.
On the other hand, when the support column is after the support step, the reinforcing column 11 incorporated in the upper rail 6 is moved to the reinforcement position, and the rod-shaped body 24b provided on the lower support member 24 is as described above. By lowering the weight of the rail 24b, the descent portion of the rod-shaped body 24b can be specified. The forming work can be performed accurately without the troublesome sizing work.

In this way, the reinforcing device 8 for reinforcing the shutter curtain 3 can be incorporated, but in this case, the reinforcing column 11 can be further incorporated into the upper rail 6 by using the upper rail 6. It is set.
As described above, the upper rail 6 attached to the upper part of the opening is provided with a reinforcing member 21 at a portion corresponding to the reinforcing position, and the hanging metal fitting 22 is detachably provided on the reinforcing member 21. Then, a simple lifting machine such as an electric hoist 26 (which may be a manual type) is engaged with the hanging metal fitting 22. Then, the locking hook 26b provided on the actuating chain 26a hanging from the hoist 26 is locked to the hanging metal fitting 27 detachably provided on the upper portion of the lower strut portion 13 of the reinforcing strut 11 via the bracket 27a. do.
By driving the hoist 26 in this locked state to lift the locking hook 26b, the upper end side of the reinforcing column 11 is lifted at the portion corresponding to the reinforcing position, and thus the reinforcing column 11 is reinforced. It is set so that it can be easily incorporated into the upper rail 6 at the site.

Next, the reinforcing vertical member 29 integrally attached to the above-mentioned reinforcing column 11 will be described in detail. The reinforcing vertical member 29 is integrally attached to the surface 13b of the front and rear double-sided portions 13b of the lower column portion 13 constituting the reinforcing column 11 on the side facing the shutter core X, and the reinforcing vertical member 29 is integrally attached to the surface 13b. Reference numeral 29 denotes a main body portion 29a which is in the shape of a square and is narrow in the left-right direction with respect to the lower support portion 13, and a leg piece portion 29b extending outward in the left-right direction from the left and right both end edges of the main body portion 29a. It has a hat-shaped cross section, and the leg piece portion 29b is welded to the one front and rear surface portion 13b to be integrated with the lower strut portion 13 and reinforced.
The reinforcing vertical member 29 has a structure in which the main body portion 29a protrudes toward the shutter core X side from the covering portion 19 and is in close contact with the shutter curtain 3 in a closed posture, and the upper end edge portion 29c is an upper support column portion. A long one that is lower than the upper end edge portion 12a of 12 and is located at a lower position close to the covering portion 19 and up to a position where the lower end edge portion 29d substantially coincides with the lower surface portion 13c of the lower support column 13. With this configuration, the upper end edge portion 29c of the reinforcing vertical member 29 is lower (lower side) than the upper end edge portion of the upper support column portion 12 constituting the reinforcing column 11, and is an opening. It is set to be located higher (upper side) than the height of 1/2 of the frontage height in E.

By the way, the shutter device 1 is provided with a magsa portion M which is a feeding port of the shutter curtain 3 from the shutter case 6 and swallows the seat plate 3a of the shutter curtain 3 when the shutter curtain 3 is fully opened. In the reinforcing vertical member 29 provided so as to face each other in close proximity to the shutter core 29a, the straddling piece portion (opposing piece portion facing the shutter core X) 29e has a magsa width in the magsa portion M in the front-rear direction with the shutter core X as a reference. It is arranged so as to face the shutter curtain 3 in the closed posture in a state where it slightly exceeds L (about several mm).
When the shutter curtain 3 bends due to a strong wind, as shown in FIG. 19, the shutter curtain 3 is in a free-end state because there is nothing to support the central portion in the left-right direction on the seat plate 3a side at the lower end. Combined with this, the part from the height of about 2/3 to 3/4 of the frontage height is greatly bent beyond the central part in the vertical direction, and for the upper part above this, the magsa part M Since there is support over the entire width of the frontage, the amount of bending can be suppressed, and the shutter curtain 3 that tries to bend in this way comes into contact with the reinforcing vertical member 29 and is received for reinforcement. It is in a state where it does not come into contact with the support column 11 (upper support column portion 12, lower support column portion 13).
Incidentally, in the present embodiment, the magsa width L has the same dimensions as the front-rear width of the guide rail 2, but the present invention is not limited to this, and the magsa width L is set with respect to the front-rear width of the guide rail 2. It may be wide or narrow.

By assuming that the reinforcing vertical member 29 is provided on the reinforcing column 11 in this way, when the shutter curtain 3 in the fully closed posture is bent by receiving a strong wind, the bent shutter curtain is described above. 3 does not abut on the strut portions 12 and 13 on both the upper and lower sides constituting the support strut portion, but abuts on the reinforcing vertical member 29 which is closely opposed to the shutter core X and is received. As a result, the shutter curtain 3 is received. The left and right edge portions of No. 3 are prevented from bending and deforming to the extent that they come out of the guide rail 4, and are configured to exhibit high wind resistance.
In this case, the reinforcing vertical member 29 extends from the lower end edge of the reinforcing column 11 to a low position not reaching the upper edge of the reinforcing column 11, and as a result, the shutter curtain 3 with which the reinforcing vertical member 29 abuts. The load received from the side becomes a large load on the lower end edge side and is supported by the floor surface F side, and the upper end edge side receives a reduced load by that amount. In this case, the upper end edge portion of the reinforcing column 11 is attached to the upper rail 9 supported by the case lower surface plate 6e adjacent to the magsa portion M, the upper frame 7, etc., but these case lower surface plates 6e and the upper portion are attached. The frame 7 is inevitably inferior in supporting strength as compared with the case of the drop portion 25 arranged on the floor portion F, but the frame 7 is supported by the upper rail 9 attached to such a portion. Even if there is, sufficient reinforcement strength can be obtained.

Moreover, in this case, the reinforcing column 11 is composed of an upper column portion 12 and a lower column portion 13, and a reinforcing vertical member 29 is provided on the lower column portion 13, and is bent by a strong wind. The member with which the shutter curtain 3 abuts and is received is substantially the lower strut portion 13. As a result, the load for receiving the bent shutter curtain 3 largely acts on the lower support column portion 13, but the lower end edge portion of the lower support column portion 13 is supported on the floor surface F side. The load can be received more firmly by the upper rail 9 in which the upper end edge portion of the upper support column portion 12 is close to the magsa portion M, and the load received by the upper rail 9 can be reduced. The strength can be increased.

In the reinforcing column 11 in which the present invention is carried out, the upper and lower edges of the reinforcing column 11 are positioned and held by the upper and lower support members 23 and 24 at the reinforcing position, while the positioning and holding of the reinforcing column 11 at the storage position. However, as a simple holding means for the reinforcing support column 11 at the storage position, the one of the present embodiment is provided on the lower holding portion 23e provided on the lower support column portion 13. Positioning and holding at the storage position by detachably connecting the fixed bracket 28a and the locking portion 28b provided on the skeleton side member such as the guide rail 2 via a connecting body such as a chain 28 or a wire. can do. Of course, as a means for holding the reinforcing column 11 at such a storage position of the reinforcing column 11, a magnetizing or tightening of a string may be used.

In the present embodiment configured as described above, the shutter curtain 3 that opens and closes the opening E is reinforced by the reinforcing columns 11 that are in close proximity to the guide rail 3 in the vertical posture. The reinforcing column 11 includes an upper column 12 provided with an upper roller 15 traveling on an upper rail 9 provided above the opening E, and a lower column provided with a lower roller 20 traveling on the floor F. As a result of the configuration in which the portions 13 are connected so as to be vertically expandable, the replenishment support column 11 can reinforce not only the central portion but also the upper and lower portions of the intermediate portion in the left-right direction in which the shutter curtain 3 has a large deflection. However, when the lower roller 20 traveling on the floor F rides on a convex non-landing surface, the lower support column 13 provided with the lower roller 20 moves upward with respect to the upper support column 12. Since the upper roller 15 is to be expanded and contracted, the upper roller 15 can overcome the uneven land while stably traveling on the upper rail 9, and the reinforcing column 11 can be smoothly moved left and right.

Moreover, in this case, in the reinforcing column 11, the load of the upper column portion 12 is received by the upper rail 9 via the upper roller 15, and the load of the lower column portion 13 is received by the floor portion F via the lower roller 20. As a result, the upper rail 9 does not need to receive the entire load of the reinforcing column 11, but only needs to receive the load of the upper column portion 12 as a result of receiving the load of the reinforcing column 11 in a distributed state. The load on the upper rail 9 can be reduced, the strength can be increased, the upper rail 9 can be made lighter and more compact, and the upper rail 9 attached above the opening E can be easily attached.

The upper strut portion 12 is male-female fitted to the lower strut portion 13 so that the reinforcing strut 11 can be expanded and contracted in the vertical direction between the upper strut portion 12 and the lower strut portion 13. Since it is fitted so that it can be expanded and contracted in the vertical direction in the superposed state, it is possible to increase the strength by increasing the width of the lower strut portion 13 that is reinforced facing the shutter curtain 3 while simplifying the structure. Become.
Moreover, since the lower strut portion 13 has a tubular shape and the upper strut portion 12 is internally fitted into the upper end portion of the lower strut portion 13 so as to be vertically expandable, the structure of the reinforcing strut 11 having a stretchable structure. The simplification of the above can be achieved while increasing the strength by making the lower strut portion 13 into which the upper strut portion 12 is internally fitted thicker.

Moreover, the shutter curtain 3 in which the reinforcing column 11 is bent by the strong wind does not abut on the upper strut portion 12, but abuts on the lower strut portion 13 to be received and supported. Therefore, the upper strut portion 12 As for the above, it is not necessary to directly receive and support the bent shutter curtain 3, and it is not necessary to make the shutter curtain 3 wider and larger as in the lower strut portion 13 that directly receives and supports the shutter curtain 3, and it is lightweight and compact. Can be achieved.
Moreover, since the lower strut portion 13 is provided with the reinforcing vertical member 13d with which the bent shutter curtain 3 abuts as described above, the reinforcing strut 11 provided with the lower strut portion 13 is reinforced. Since the vertical member 13d is provided, the arrangement can be made away from the shutter curtain 3 (curtain core X), and the arrangement of the upper rail 9 can be set to a position that does not interfere with the opening / closing operation of the shutter curtain 3. It does not interfere with the opening and closing operation of the shutter curtain 3.

In this case, since the lower end portion of the upper strut portion 12 is located at the upper portion of the reinforcing strut 11, the load in the indoor / outdoor direction received when the bent shutter curtain 3 is received and supported is long and lower. The side strut portion 13 receives the load directly, and the upper strut portion 12 indirectly receives this load through the portion where both strut portions 12 and 13 overlap (stack), but the upper strut portion 12 Is short (short) on the upper rail 9 side, so that it works favorably in terms of moment. As a result, the upper strut portion 12 is fitted into the lower strut portion 13 to be thin. Even if it has a width, it becomes advantageous in terms of strength, the weight of the upper strut portion 12 can be reduced, and the load on the upper rail 9 on which the load of the upper strut portion 12 works can be reduced, which contributes to the increase in strength. can do.

Further, the upper strut portion 12 is provided so as to surround the strut body portion 14 that is loosely fitted in the lower strut portion 13 and the outer periphery of the strut body portion 14, and is close to the inner surface of the lower strut portion 13. The support main body portion 14 has an extension portion 14d extending downward from the lower end portion of the outer shell portion 18, and the extension portion 14 is provided with an outer shell portion 18 having facing surface portions. A sphere 14e is provided on the 14d so as to face the inner surface of the left and right side surface portions 13a of the lower strut portion 13. Then, for example, in the process of moving the reinforcing support column 11 in the left-right direction, when the lower support column portion 13 tries to tilt relative to the upper support column portion 12 in the left-right direction, the outer shell is formed in the lower support column portion 13 on the upper side. The upper end of the portion 18 abuts on the inner surface of the left and right side surface portions 13a of the lower strut portion 13, and the sphere 14e abuts on the inner surface of the left and right side surface portions 13a of the lower strut portion 13 on the lower side. As a result of the structure, the upper strut portion 12 and the lower strut portion 13 are restricted from being tilted more than necessary, and the reinforcing strut 11 is smoothly moved left and right while maintaining a substantially vertical posture. Become.
Moreover, in this case, since the sphere 14e becomes rotatable in all directions and comes into contact with the inner surfaces of the left and right side strut portions 13a of the side strut portion 13, the upper strut portion 12 and the lower strut portion 13 are displaced in the front-rear direction. Even if the sphere is tilted in the state, the corresponding sphere 14e can be abutted and abutted, so that it is possible to effectively avoid the upper strut portion 12 and the lower strut portion 13 from being jerky.

Further, in this case, the reinforcing support column 11 is configured such that the upper support column portion 12 is fitted inwardly with respect to the lower support column portion 13 in the vertical direction, but the upper support column portion 12 has a lower support column portion. A covering portion 19 having a top surface portion 19a covering the upper end portion of 13 and a side surface portion 19b hanging from the peripheral edge portion of the top surface portion 19a and covering the side surface portion of the lower strut portion 13 is provided. As a result, it is possible to prevent foreign matter such as rainwater and dust from entering through the gap between the lower strut portion 13 and the upper strut portion 12.

Further, the lower strut portion 13 includes an upper support member 23 for positioning and supporting the lower strut portion 13 in a state where the reinforcing strut 11 is located at the reinforcing position on the upper rail 9, and a lower strut portion 13 for positioning and supporting the floor portion F. As a result of the provision of the lower support member 24, the reinforcing column 11 located at the reinforcing position is positioned and supported by the upper and lower support members 23 and 24 provided on the lower support member 13. The upper strut portion 12 that can be expanded and contracted vertically with respect to the lower strut portion 13 is not positioned and supported, and the lower strut portion 12 that substantially contributes to the reinforcement of the shutter curtain 3 is vertically positioned and supported. This will stabilize the reinforcement.

Moreover, the upper support member 23 is provided with a support metal fitting 23a provided on the lower strut portion 13 and a rod-shaped body 23c provided so as to be vertically operable in the positioning posture and the release posture. Is provided with a stopper piece 9i that interferes with the rod-shaped body 23c positioned in the positioning posture and regulates the movement of the reinforcing column 11 to the storage position side, so that the stopper piece 9i is provided on the upper side of the opening E. It is not necessary to provide a regulating member corresponding to the stopper piece 9i, and the structure can be simplified.
Further, the upper rail 9 is provided with a reinforcing member 21 at a portion corresponding to the reinforcing position of the reinforcing column 11, and as a result of the portion being reinforced, the load from the shutter curtain 3 side is received in a reinforced state. Therefore, the strength can be increased.

Further, the lower roller 20 is set to move in the left-right direction in a state where the direction around the vertical axis cannot be changed, and the pair of lower rollers 20 are displaced in the front-back and left-right directions. As a result of being provided at the lower end of the lower strut portion, when the lower strut portion 13 is moved in the left-right direction, the movement of bending in the front-rear direction is restricted and the lower strut portion 13 is positively guided in the left-right straight line direction. It will be possible to move stably from side to side.

It should be noted that the present invention is not limited to the above embodiment, and can also be implemented as the second embodiment shown in FIGS. 20 and later, which will be described below. In this case, the same items as those in the first embodiment shall be designated by the same withdrawal code.
In this case, the structure of the reinforcing vertical member 29 is mainly different from that of the first embodiment.

The reinforcing vertical member 29 of the second embodiment has a cross-section hat type, and is integrally attached to the front and rear surface portions 13b on the side of the lower strut portion 13 facing the shutter core X, and the upper end edge. The first embodiment is that the portion 29c is located above the height of 1/2 of the opening height and the lower end edge portion 29d is located at the same position as the lower surface portion 13c of the lower strut portion 13. However, by setting the upper end edge portion 29c to be lower than that of the first embodiment and to be about 2/3 of the frontage height. The upper end edge portion 29c is set to be lower than that of the first embodiment and lower than the lower end edge portion of the column main body portion 14, and as a result, the reinforcing vertical member 29 is lowered by the amount. When the shutter curtain 3 bends due to a strong wind while the weight of the reinforcing column 11 can be reduced, the reinforcing column 11 is provided with a receiving support at a portion where the amount of bending of the shutter curtain 3 is substantially large. It is possible to prevent the bent shutter curtain 3 from coming out of the guide rail 2 because it is formed by the reinforcing vertical member 29 in a non-contact state.
By lowering the height of the reinforcing vertical member 29 in this way, the load when the reinforcing vertical member 29 receives and supports the bent shutter curtain 3 is the height of the reinforcing vertical member 29 equal to the frontage height of 2. When the height is set to / 3, the stress acts on the floor surface F side as 2/3 and on the magsa portion M side as 1/3, and is greatly received on the floor surface F side where the support strength can be set large. It can be made into a product and can contribute to increasing the strength.

Further, in this case, the upper end edge portion 29c of the reinforcing vertical member 29 has an inclined surface inclined toward the shutter curtain 3 side toward the lower side, while the lower end edge portion 29d conversely becomes the shutter curtain 3 side toward the upper side. When the shutter curtain 3 is opened and closed while the reinforcing column 11 is set at the reinforcing position, the seat plate 3a becomes the upper end edge portion 29c of the reinforcing vertical member 29. Consideration is given to avoid being caught in the lower end edge portion 29d and disturbing the opening / closing posture.
Moreover, as a result of the cushioning material 30 being provided on the straddle portion 29e and the upper and lower both end edges 29c and 29d which are the facing surfaces of the shutter curtain of the reinforcing vertical member 29, the shutter curtain (seat plate 3a, slats 3b) 3 is bent. Can contribute to the prevention of noise generation by cushioning the impact when the reinforced vertical member 29 comes into contact with the reinforced vertical member 29, and can also prevent damage to the reinforced vertical member 29 and the shutter curtain 3.

Further, in the second embodiment, the arrangement position of the support member 23 for setting and maintaining the reinforcing column 11 in the storage position and the reinforcing position is different from that of the first embodiment. This configuration will be described below.
In the first embodiment, the support member 23 is provided on one side surface portion 13a in the left-right direction of the lower strut portion 13, but in the second embodiment, the support member 23 is provided on the outer surface portion 13b in the front-rear direction. There is. With such a configuration, the support member 23 can be operated from the outside in the front-rear direction of the opening E, and the skeleton side member does not come close to each other and interfere with the storage position, and the first implementation is described above. The operability is superior to that in the case of the above form. Moreover, the upper rail 9 is provided with stopper materials 9k and 9l corresponding to the storage position and the reinforcement position of the reinforcing column 11, and the stopper materials 9k and 9l are the stopper pieces 9i and 9j of the first embodiment. Instead of the L-shaped single plate shape provided on the upper rail upper piece portion 9a as in the above, a glyph-shaped one is provided in a state of projecting to the outside of the side piece portion 9b of the upper rail 9. It has become a thing.
In this case, the pair of left and right stopper members 9l provided at the reinforcing position are welded to the vertical piece portion 21a and the upper piece portion 21b of the reinforcing member 21 provided at the portion, thereby causing the reinforcing member 21 itself to be welded. Consideration was given to reinforcing the upper rail 9, so that the stopper member 9l could be used as the reinforcing material for further reinforcement of the portion corresponding to the reinforcing position of the upper rail 9.
