Description

[Technical field]

[0001] The present invention relates to a telescopic door body and a telescopic gate that can be adjusted along an installation surface on a slope. [Background technology]

[0002] Conventionally, a double-leaf gate composed of left and right telescopic gates (telescopic door bodies) attached to left and right support pillars, respectively, has been known (see Patent Document 1). Each of the left and right telescopic gates has a hinged end member fixed to the support pillar, and a door end member connected to the door end member via a pantograph mechanism so as to be slidable in the left and right direction, and the door end members of the left and right telescopic gates are provided with a lock and a lock receiver so that they can be locked to each other. The door end member has an outer member (vertical frame) and an inner member (vertical bar), and the pantograph mechanism described above is connected to the inner member. The outer member is provided with the lock and lock receiver described above and is attached to the inner member so that its height can be adjusted up and down, so that it can be appropriately installed even on a slope that is inclined relative to the horizontal direction, for example.

[0003] [Patent Document 1] JP 2010-236235 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the retractable gate described in Patent Document 1, a long hole is formed in the outer member at the door leading end member along the up-down direction with respect to a vertical plate along the front-rear direction (front view direction) perpendicular to the left-right direction, and the outer member is attached to the inner member by inserting a screw that passes through the inner member in the left-right direction (front view direction of the door leading end member) into the long hole and screwing it into a nut. With the door leading side member configured in this way, the outer member can be adjusted up and down relative to the inner member by loosening the screw, and the outer member can be fixed to the inner member by tightening the screw. However, since the above-mentioned screws for attaching the outer member to the inner member are inserted in the prospective direction, it is necessary to form screw insertion holes into which the screws are inserted in parts of the inner member along the prospective direction, or to attach gaps or the like to close these screw insertion holes and reduce their exposure to the outside. In this case, a certain degree of prospective dimension is required for the inner member in order to form the above-mentioned screw insertion holes or to attach screw insertion hole caps or the like, so it is difficult to reduce the prospective dimension of the inner member in a configuration in which the height of the outer member is adjustable up and down.

[0005] An object of the present invention is to provide a telescopic door body and a telescopic gate door that can be appropriately installed along an installation surface on a slope while reducing the projected dimensions of the vertical bars. [Means for solving the problem]

[0006] The telescopic door body of the present invention is a telescopic door body that can be telescopic in the left-right direction, and includes a telescopic mechanism that can be telescopic in the left-right direction, a vertical bar provided on the telescopic mechanism, and a vertical frame that is attached to the vertical bar so as to be height-adjustable via a height adjustment member, and the vertical bar has a vertical bar fixed part on the inner side in the projection direction, the vertical frame has a vertical frame fixed part that opens on the inner side in the projection direction and forms a groove along the up-down direction in which a back plate is arranged, and the height adjustment member is a vertical bar fixed part. the vertical bar fixing portion is fixed to a back plate and a vertical stile fixing portion is continuous with the vertical bar fixing portion and fixed to the vertical stile fixed portion, the vertical bar fixing portion and the vertical stile fixing portion are arranged straddling the vertical bar fixed portion and the vertical stile fixed portion on the inner surface side in the projection direction of the vertical bar and the vertical stile, and the vertical stile fixing portion is screwed and fixed to the back plate by a fixing device that passes through the opening and cooperates with the back plate to clamp the vertical stile fixed portion so that it can be slidably adjusted in the vertical direction. The telescopic gate of the present invention is characterized by comprising a pair of left and right gate posts and the telescopic door body of the present invention described above which is attached to one of the pair of left and right gate posts so as to be able to extend and retract in the left-right direction.

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Fig. 1, the retractable gate 1 according to this embodiment is installed on a mounting surface GL on a sloping ground to open and close an entrance to and from a site such as a car parking lot, and is configured as a double-leaf type with a pair of left and right gate posts 2A, 2B, a retractable door body 10A whose hanging side is attached to the gate post 2A, and a retractable door body 10B whose hanging side is attached to the gate post 2B. The retractable door bodies 10A, 10B are configured so that they can be locked and unlocked by each other at their respective door end sides. In the following description, the left-right direction of the telescopic gate 1 is the X-axis direction, the up-down direction of the telescopic gate 1 is the Y-axis direction, and the projection direction of the telescopic gate 1 (into and out of the premises) is the Z-axis direction. The X, Y, and Z axis directions are mutually perpendicular.

[0010] The telescopic door body 10A comprises a pantograph mechanism 11 as a telescopic mechanism capable of expanding and contracting in the X-axis direction, a plurality of vertical bars 12 arranged along the Y-axis direction and provided on the pantograph mechanism 11, a vertical frame 13 on the door-end side that is height-adjustably attached to a vertical bar 121 located on the door-end side among the plurality of vertical bars 12 via a height adjustment member 30 described later, and a vertical frame 14 on the hanging side to which the pantograph mechanism 11 is attached on the door tail side. In addition, since each component of the telescopic door body 10B is configured in a manner similar to each component of the telescopic door body 10A, the same symbols as those of the telescopic door body 10A are used for the telescopic door body 10B, and detailed explanations thereof will be omitted.

[0011] The pantograph mechanism 11 is composed of multiple connecting shafts 111 that are connected to each other so as to be rotatable across each other, and when extended, the multiple connecting shafts 111 form multiple diamond-shaped spaces, and when contracted, the multiple connecting shafts 111 crush and eliminate the spaces. Of the multiple connecting shafts 111, the end of the connecting shaft 111 located on the hanging side is rotatably connected to the vertical frame on the hanging side.

[0012] The multiple vertical bars 12 include vertical bar 12A that is connected to the intersection of the multiple connecting shaft members 111 from outside the site, and vertical bar 12B that is connected to the intersection of the multiple connecting shaft members 111 from inside the site.The multiple vertical bars 12 lined up in the X-axis direction are arranged at equal intervals in the X-axis direction when the pantograph mechanism 11 is extended, and approach each other so as to overlap in the X-axis direction when the pantograph mechanism 11 is retracted. Since the multiple vertical bars 12 (12A, 12B) are formed in the same manner, the specific configuration will be described in detail with respect to the vertical bar 121 located at the door end side among the multiple vertical bars 12, and the configurations of the other vertical bars 12 will be appropriately assigned the same symbols as the configurations of the vertical bar 121 and descriptions of these will be omitted. 2 to 4, the vertical bar 121 is formed of an aluminum extrusion and includes an arc-shaped outer piece portion 122, a pair of side piece portions 123 extending in the Z-axis direction from both ends of the outer piece portion 122, a pair of bent portions 124 formed by bending the edges of the pair of side piece portions 123 in the X-axis direction toward the inside of the vertical bar 121, and a vertical bar fixed portion 126 composed of a pair of pieces 125 extending in the X-axis direction from each of the continuous portions of the outer piece portion 122 and the pair of side piece portions 123 toward the inside of the vertical bar 121. An opening 127 is formed between the pair of pieces 125, and an opening 128 is formed between the pair of bent portions 124. The outer piece 122 and the vertical bar fixed part 126 form a groove 120 (rear chamber, vertical bar groove) along the Y-axis direction on the inner side (inner side in the Z-axis direction) of the outer piece 122, and the vertical bar fixed part 126, the side piece 123 and the bent part 124 form a front chamber 129 along the Y-axis direction. Furthermore, the vertical bar fixed part 126 is formed with a cutout part 125A formed by cutting out a part of the pair of pieces 125, and the protruding part 312 described later engages with this cutout part 125A. A cap 6 for hiding the fore-edge is attached to the upper end of the vertical bar 121, and a wheel 7 for running on the installation surface GL is attached to the lower end of the vertical bar 121. The vertical bars 12 other than the vertical bar 121 have a cap 6 attached to their upper end and a wheel 7, a cap 6 for hiding the fore-edge or a drop lock 8 attached to their lower end (see FIG. 1). 2A is an external view showing the vertical bars 121 and vertical frames 13 of the telescopic door bodies 10A and 10B from the front, and FIG. 2B is a cross-sectional view showing the vertical bars 121 and vertical frames 13 of the telescopic door bodies 10A and 10B.

[0013] As shown in Figures 2 to 4, the vertical frame 13 on the door end side is formed of an aluminum extrusion, and includes a pair of vertical frame sight pieces 131 along the X-axis direction, a vertical frame projection piece 132 along the Z-axis direction that is continuous with the pair of vertical frame sight pieces 131, and a vertical frame fixed part 135 composed of a pair of pieces 134 that extend in the Z-axis direction from each of the pair of vertical frame sight pieces 131 toward the inside of the vertical frame 13 and have a bent part 133 bent so that their end edges approach each other in the X-axis direction. At least one of the lock 3 and the lock receiver 4 is provided on the vertical frame projection piece 132, and a handle 5 is provided on the pair of vertical frame sight pieces 131 for operating the lock 3 and sliding the vertical frame 13 in the X-axis direction. The vertical frame fixed portion 135 has a groove 130 (vertical frame groove) along the Y-axis direction formed on the inner surface side in the Z-axis direction of the vertical frame spot piece portion 131. The groove 130 communicates with an opening 136 formed between a pair of bent portions 133. Caps 9 for hiding the fore-edge are attached to the upper and lower ends of the vertical frame 13.

[0014] The vertical frame 14 on the hanging side is made of the same material and has the same shape as the vertical frame 13 on the door end side, so a description of the vertical frame 14 will be omitted. The vertical frame 14 of the telescopic door body 10A is attached to the gatepost 2A via a hinge 141 so as to be rotatable on at least one side in the Z-axis direction, and the vertical frame 14 of the telescopic door body 10B is attached to the gatepost 2B via a hinge 141 so as to be rotatable on at least one side in the Z-axis direction.

[0015] 2 to 4, the height adjustment member 30 is a metal fitting made of a metal material such as steel, and has a vertical bar fixing portion 31 and a vertical frame fixing portion 32 that are rectangular pieces along the X-axis direction, and a continuous portion 33 that connects the vertical bar fixing portion 31 and the vertical frame fixing portion 32, and is screwed and fixed to the back plates 51 and 52 that are placed in the grooves 120 and 130 of the vertical bar 121 and the vertical frame 13 by a fixing bolt 53 and an adjustment bolt 54 as fixing devices. The vertical bar fixing portion 31 and the vertical frame fixing portion 32 are located at different positions in the Z-axis direction, and in this embodiment, the position of the vertical bar fixing portion 31 is located outside the position of the vertical frame fixing portion 32 in the Z-axis direction.

[0016] The vertical bar fixing portion 31 is formed with a hole 311 through which the fixing bolt 53 is inserted, and a pair of left and right protruding portions 312 protruding toward the vertical bar fixed portion 126 . The pair of left and right protruding parts 312 engage with the pair of left and right notched parts 125A formed in the pair of pieces 125 in a state where the vertical bar fixing part 31 is abutted against the vertical bar fixed part 126 so as to be immovable at least in the Z-axis direction. This allows positioning above and below the vertical bar fixing part 31. Furthermore, a fixing bolt 53 is inserted into the hole 311, and the fixing bolt 53 inserted into the hole 311 is screwed into the back plate 51. Here, the back plate 51 is formed in a vertically elongated rectangular plate shape and has a pair of upper and lower screw holes 511 into which the fixing bolt 53 can be screwed, and is configured so that the fixing bolt 53 can be screwed into either one of the pair of upper and lower screw holes 511 even if the back plate 51 is arranged upside down.

[0017] The vertical frame fixing part 32 has a hole 321 through which the adjustment bolt 54 is inserted, and a holding piece 322 formed at the upper and lower ends in the Y-axis direction and bent in the Z-axis direction toward the vertical frame fixed part 135. The adjustment bolt 54 is inserted into the hole 321, and the adjustment bolt 54 inserted into the hole 321 is screwed into the back plate 52. The upper and lower holding pieces 322 hold the back plate 52 in the Y-axis direction. Here, the back plate 52 is formed in a vertically elongated rectangular plate shape and has a pair of upper and lower screw holes 521 into which the adjustment bolt 54 can be screwed, and is configured so that the adjustment bolt 54 can be screwed into either one of the pair of upper and lower screw holes 511 even if the back plate 52 is arranged upside down.

[0018] 4, the continuous portion 33 extends in the Z-axis direction and is formed in a step shape (crank shape), and connects the upper and lower ends of the vertical bar fixing portion 31 and the vertical frame fixing portion 32 to each other. As a result, the vertical bar fixing portion 31 is disposed toward the outside in the Z-axis direction, and the vertical frame fixing portion 32 is disposed toward the inside in the Z-axis direction, so that the vertical bar fixing portion 31 and the vertical frame fixing portion 32 are disposed at positions corresponding to the positions of the vertical bar fixed portion 126 and the vertical frame fixed portion 135 in the Z-axis direction. Note that a vertically long hole 331 is formed in the center of the continuous portion 33, and the vertical bar fixing portion 31 is formed to protrude beyond this hole 331 in the Z-axis direction.

[0019] In this height adjustment member 30, the vertical bar fixing part 31 and the vertical frame fixing part 32 are arranged across the vertical bar fixed part 126 and the vertical frame fixed part 135 on the inner surface side in the Z-axis direction of the vertical bar 121 and the vertical frame 13, and the vertical frame 13 is fixed to the vertical bar 121 by tightening the fixing bolt 53 and the adjustment bolt 54 with the back plates 51, 52 arranged in the groove parts 120, 130. Also, the vertical position of the vertical frame 13 with respect to the vertical bar 121 can be adjusted by loosening the adjustment bolt 54.

[0020] In the telescopic gate 1 described above, the vertical frames 13 of the telescopic door bodies 10A, 10B are attached to the vertical bars 121 using the height adjustment member 30 as follows so that they can be locked together, and the height position of the vertical frames 13 is appropriately adjusted. Note that Fig. 4(A) shows the height adjustment member 30, back plates 51, 52, fixing bolts 53 and adjustment bolts 54 disassembled, and Fig. 4(B) shows the vertical frame 13 attached to the vertical bars 121 using the height adjustment member 30. First, the fixing bolts 53 and the adjustment bolts 54 are inserted into the holes 311 and 321 of the height adjustment member 30, and the back plates 51 and 52 are loosely screwed onto the fixing bolts 53 and the adjustment bolts 54 that have been inserted. Next, the back plates 51, 52 are inserted into the grooves 120, 130 from the ends in the Y-axis direction of the vertical bar 121 and the vertical frame 13. At this time, the vertical frame fixing part 31 is inserted into the front chamber 129 of the vertical bar 121 and faces the vertical frame fixed part 126 in the Z-axis direction, and the vertical frame fixing part 32 faces the vertical frame fixed part 135 in the Z-axis direction. At this time, the crank-shaped continuing part 33 is abutted in the X-axis direction against the bent part 124 at the side piece part 123 of the vertical bar 121 located on the vertical frame 13 side, thereby determining the position of the height adjustment member 30 in the X-axis direction. Next, the protruding portion 312 of the vertical bar fixing portion 31 is engaged with the cutout portion 125A of the vertical bar fixed portion 126 to determine the vertical position of the vertical bar fixing portion 31 relative to the vertical bar 121, and the fixing bolt 53 is tightened to cooperatively hold the vertical bar fixing portion 126 between the vertical bar fixing portion 31 and the back plate 51, thereby fixing the vertical bar fixing portion 31 of the height adjustment member 30 to the vertical bar 121. At this time, the fixing bolt 53 is housed inside the vertical bar 121. Next, with the adjustment bolt 54 still in the loosened state before being tightened, the vertical frame 13 is slid in the Y-axis direction relative to the vertical bar 121, and with the vertical frame 13 positioned in the appropriate position, the adjustment bolt 54 is tightened so that the vertical frame fixing portion 32 and the back plate 52 cooperate to clamp the vertical frame fixed portion 135, thereby fixing the vertical frame fixing portion 32 of the height adjustment member 30 to the vertical frame 13. In this way, in the retractable gate 1 of this embodiment, the vertical frame 13 on the door end side is adjusted and fixed in the Y-axis direction relative to the vertical bar 121 by the height adjustment member 30. Also, the height adjustment member 30 is arranged along the Z-axis direction relative to the vertical bar fixed part 126 and the vertical bar fixed part 135, which have openings 127, 136 on the inner side in the Z-axis direction of the vertical frame 13 and the vertical bar 121, and the fixing bolt 53 and the adjustment bolt 54 are arranged along the Z-axis direction instead of the X-axis direction, so there is no need to attach a screw insertion hole or a hole-closing cap to the side piece part 123 of the vertical bar 121, and there is no need to secure a projected dimension for this, and therefore the projected dimension of the vertical bar 121 can be made small.

[0021] [Variations] In the above embodiment, a double-leaf retractable gate 1 has been described, but a single-leaf retractable gate 1B may also be configured, for example as in the modified example shown in Fig. 5. A single-leaf retractable gate 1B has only one of the retractable door bodies 10A, 10B, with the vertical frame 14 on the hinge side attached to the gatepost 2A and the vertical frame 13 on the door end side arranged to face the gatepost 2B. A lock receiver 4 is provided on the gatepost 2A, and is configured to be lockable with the lock 3 provided on the vertical frame 13.

[0022] In the above embodiment, the fixing bolt 53 that screw-fixes the vertical bar fixing portion 31 of the height adjustment member 30 to the back plate 51 is arranged within the vertical bar 121, but this is not limited to the above and the fixing bolt 53 may be arranged to protrude from the opening 128 of the vertical bar 121. In the above embodiment, the vertical bar fixed portion 126 and the vertical frame fixed portion 135 are positioned at different positions in the Z axis direction, and accordingly, the vertical bar fixing portion 31 and the vertical frame fixing portion 32 are also positioned at different positions in the Z axis direction, and the connecting portion 33 is formed in a stepped shape; however, for example, when the vertical bar fixed portion 126 and the vertical frame fixed portion 135 are positioned at the same position in the Z axis direction and along the X axis direction, the vertical bar fixing portion 31 and the vertical frame fixing portion 32 may also be positioned at the same position in the Z axis direction and along the X axis direction, and the connecting portion 33 may also be shaped along the X axis direction. In the above embodiment, a protrusion 312 is formed in the vertical bar fixing portion 31 and a cutout portion 125A is formed in the vertical bar fixed portion 126, but these configurations may be omitted if the height adjustment member 30 can be fixed immovably to the vertical bar 121. In the above embodiment, upper and lower retaining pieces 322 are formed on the vertical frame fixing portion 32, but the configuration of the retaining pieces 322 may be omitted if the vertical frame 13 can be adjusted and fixed up and down without the back plate 52 being held up and down by the upper and lower retaining pieces 322.

[0023] [Summary of the invention] (1) The telescopic door body of the present invention is a telescopic door body that can be telescopic in the left-right direction, and includes a telescopic mechanism that can be telescopic in the left-right direction, a vertical bar provided on the telescopic mechanism, and a vertical frame that is attached to the vertical bar so as to be height-adjustable via a height adjustment member, and the vertical bar has a vertical bar fixed part on the inner side in the projection direction, and the vertical frame has a vertical frame fixed part that opens on the inner side in the projection direction and forms a groove along the up-down direction in which a back plate is arranged, and the height adjustment member is a part of the vertical bar fixed part. The device has a vertical bar fixing portion fixed to a fixing portion, and a vertical stile fixing portion that is continuous with the vertical bar fixing portion and fixed to the vertical stile fixed portion, the vertical bar fixing portion and the vertical stile fixing portion being arranged straddling the vertical bar fixed portion and the vertical stile fixed portion on the inner surface side in the projection direction of the vertical bar and the vertical stile, and the vertical stile fixing portion is screwed and fixed to a back plate by a fixing device that passes through the opening and cooperates with the back plate to clamp the vertical stile fixed portion so that it can be slidably adjusted in the vertical direction. According to the telescopic door body of the present invention, the vertical bar fixing part and the vertical frame fixing part of the height adjustment member are arranged across the vertical bar fixed part and the vertical frame fixed part on the inner side in the projection direction of the vertical bar and the vertical frame, and the vertical frame is attached to the vertical bar using this height adjustment member, so that, compared to the case where an insertion hole for a fixing screw or the like or a cap for hiding the hole is provided in the projection part of the vertical bar, it is possible to eliminate the need to ensure a projection dimension for providing a fixing screw or the like or a cap in the projection part, and thus the projection dimension of the vertical bar can be reduced. Also, by loosening the fixing tool that screws the vertical frame fixing part to the back plate, the vertical frame fixed part can be adjusted in the vertical direction so that the vertical frame can be adjusted in the height direction relative to the vertical bar, while by tightening the fixing tool, the vertical frame fixed part can be fixed to the vertical frame fixing part so that the vertical frame can be fixed immovably to the vertical bar. Therefore, according to the present invention, by adjusting the height of the vertical frame on which a lock, lock receiver, etc. can be attached, the telescopic door body can be appropriately installed along the installation surface on a slope, and the projected dimension of the vertical bar in such a telescopic door body can be reduced. (2) In the retractable door body of the present invention, the vertical bar fixed portion has a groove portion that opens on the inner side in the projection direction and runs in the vertical direction, and the vertical bar fixing portion is screwed and fixed to the back plate by a fastener that passes through the opening and cooperates with the back plate to clamp the vertical bar fixed portion so that it can be slidably adjusted in the vertical direction. According to this configuration, with the vertical bar fixing part loosely connected to the back plate by the fastener, the back plate can be slid vertically into the groove of the vertical bar fixed part, and then the fastener can be tightened at a predetermined position to easily fix the vertical bar fixing part to the vertical bar fixed part. In the vertical stile, the vertical stile fixing part can be easily fixed to the vertical stile fixed part by loosely connecting the vertical stile fixing part to the back plate by the fastener, sliding the back plate vertically into the groove of the vertical stile fixed part, and then tightening the fastener. This allows the height adjustment member to be easily fixed to the vertical bar or the vertical stile. (3) In the telescopic door body of the present invention, the fastener that screw-fits the vertical bar fixing portion to the back plate may be disposed inside the vertical bar. According to this configuration, the fastener can be disposed in an inconspicuous position on the vertical bar, thereby improving the design. (4) In the telescopic door body of the present invention, the vertical bar fixed portion and the vertical frame fixed portion are arranged at different positions from each other in the projection direction, and the continuous portion of the vertical bar fixing portion and the vertical frame fixing portion can be formed in a stepped shape so that the vertical bar fixing portion and the vertical frame fixing portion are each arranged at a position corresponding to the position of the vertical bar fixed portion and the vertical frame fixed portion in the projection direction. With this configuration, the continuous portion of the vertical bar fixing portion and the vertical frame fixing portion is formed in the step shape described above, so that the continuous portion can be fitted to the vertical bar or vertical frame in the facing direction, making it easy to install the height adjustment member. (5) In the retractable door body of the present invention, a protruding portion is formed in the vertical bar fixing portion, and a notch portion is formed in the vertical bar fixed portion by cutting out a part of it, and the protruding portion may engage with the notch portion so as to be immovable at least in the vertical direction when the vertical bar fixing portion is fixed to the vertical bar fixed portion. With this configuration, by forming the cutout portion at a predetermined position in the vertical direction relative to the vertical bar fixing portion, the height adjustment member can be easily positioned at a predetermined position in the vertical direction relative to the vertical bar by engaging the protruding portion with the cutout portion. (6) In the retractable door body of the present invention, the upper and lower ends of the vertical frame fixing portion may be bent in the projection direction and formed with a retaining piece that holds the back plate to which the fixing device is screwed in the vertical direction. With this configuration, when the vertical frame fixing portion is fixed to the back plate by the fixing device, the back plate can be temporarily held in the vertical direction by the holding piece. (7) The retractable gate of the present invention is characterized by comprising a pair of left and right gate posts and the retractable door body of the present invention described above which is attached to one of the pair of left and right gate posts so as to be able to retract and expand in the left-right direction. According to the telescopic gate of the present invention, it is possible to configure a telescopic gate that can achieve the same effects as those of the telescopic door body of the present invention described above. (8) The telescopic gate of the present invention comprises a pair of telescopic door bodies, and the hanging sides of each of the pair of telescopic door bodies are attached to the gate post to form a double-hinged gate, the vertical frames of the pair of telescopic door bodies are respectively arranged on the leading ends of the pair of telescopic door bodies and are configured to be lockable to each other, and the vertical frame on the leading end side of at least one of the pair of telescopic door bodies may be attached to the vertical bar of the one of the pair of telescopic door bodies via the height adjustment member so as to be height-adjustable. According to this configuration, by attaching at least one of the vertical frames of a pair of double-opening telescopic door bodies via the height adjustment member described above, even if the installation surface is on a slope and the positions of the pair of vertical frames are misaligned in the vertical direction, the height of the vertical frame can be adjusted using the height adjustment member, and the vertical positional misalignment of the vertical frame on the door end side of the pair of telescopic door bodies can be corrected.
