Description

[Technical Field]

[0001] The present invention relates to a fence. [Background technology]

[0002] Traditionally, lattice fences have been installed as fences to surround gardens or residences. A lattice fence is made by joining thin timbers vertically and horizontally, or with gaps in either direction. By installing a lattice fence, it is possible to restrict visibility from the outside. Examples of lattice fences are described in the following patent documents. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 54-103061 [Patent Document 2] Japanese Utility Model Application Publication No. 51-81539 [Patent Document 3] Jikko No. 56-15329 [Patent Document 4] Japanese Utility Model Application Publication No. 57-77596 [Patent Document 5] Japanese Utility Model Application Publication No. 60-70195 [Patent Document 6] Japanese Utility Model Application Publication No. 7-32003 [Patent Document 7] Japanese Patent Application Laid-Open No. 2003-155847 [Patent Document 8] No. 3233489 publication Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the fences according to the background art in terms of more effectively restricting visibility from the outside.

[0005] For example, a lattice fence according to the background art is composed of multiple panels arranged at predetermined intervals, with gaps formed between each panel. The presence of these gaps ensures visibility from inside to outside, providing users with a sense of openness. Meanwhile, the panels have a predetermined thickness, which allows them to block visibility in the direction of inclination relative to the lattice fence.

[0006] However, it is difficult to block the view perpendicular to the lattice fence because it passes through the gaps between the panels. This can result in a loss of privacy and a decrease in security. While installing a separate panel to cover the gap would block the view from the outside through the gap, it would also block the view from inside to the outside, potentially reducing the sense of openness for users.

[0007] Furthermore, commercially available lattice fences are surrounded by a frame on the periphery, which means that as the size of the lattice fence increases, the manufacturing costs increase and it becomes less convenient to use.

[0008] Furthermore, in the fences related to the background art, the fixed and movable gratings are attached via support members, so there is a distance between the fixed and movable gratings equal to the thickness of the support members, and there is a problem in that a gap of this distance is created when the fences are in a shielded state.

[0009] The present invention was made in consideration of these problems, and its object is to provide a fence that can block the view from the front outside as necessary while ensuring the user's view to the outside. [Means for solving the problem]

[0010] The fence of the present invention comprises a fixed lattice fence fixed to an installation surface, a movable lattice fence configured to be displaceable relative to the fixed lattice fence, and a panel movement mechanism that moves the movable lattice fence along the width direction, and is capable of taking an open state in which gaps in the fixed lattice fence are not covered by the movable lattice fence, and a shielded state in which gaps in the fixed lattice fence are covered by the movable lattice fence, the fixed lattice fence has a plurality of fixed panels that are spaced apart along the width direction and do not move in the open state or the shielded state, and the movable lattice fence has a plurality of movable panels that are spaced apart along the width direction and move in the open state and the shielded state. a movable panel connecting portion having a spring and extending in the horizontal direction so as to connect the movable panels together, wherein a first end side of the movable panel in the width direction is rotatably supported relative to the fixed panel, and a second end side of the movable panel in the width direction is rotatably connected to the movable panel connecting portion, and in the open state, the movable panel is approximately perpendicular to the direction in which the movable panel connecting portion extends and is in close contact with the fixed panel, and in the closed state, the movable panel is approximately parallel to the direction in which the movable panel connecting portion extends and moves away from the fixed panel to close the gap. The fence of the present invention includes a fixed grid fence fixed to the installation surface, a movable grid fence configured to be displaceable with respect to the fixed grid fence, and a panel movement mechanism for moving the movable grid fence along the width direction. The gap of the fixed grid fence can be in an open state not covered by the movable grid fence and a shielded state covered by the movable grid fence. The fixed grid fence has a plurality of fixed panels arranged at intervals along the width direction and not moving in the open state and the shielded state. The movable grid fence has a plurality of movable panels arranged at intervals along the width direction and moving in the open state and the shielded state. The movable grid fence further includes a movable panel connecting portion extending along the lateral direction so as to connect the movable panels. The side of the first end in the width direction of the movable panel is rotatably supported with respect to the fixed panel, and the side of the second end in the width direction of the movable panel is rotatably connected to the movable panel connecting portion. In the open state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends and is in close contact with the fixed panel. In the shielded state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends and closes the gap by moving away from the fixed panel. The fence is characterized by this. [Effects of the Invention]

[0011] According to the fence of the present invention, the movable panel can be rotated by operating the movable panel connector, allowing easy switching between the open state and the closed state. Furthermore, according to the present invention, one end of the fixed grid and one end of the movable grid are directly joined through hinges or slits, so there are no gaps as described above, making it possible to create a nearly complete closed state.

Best Mode for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the structure of the lattice fence 10 and the like will be described using various directions such as the outside, the inside, left and right, up and down. Here, the outside refers to the direction facing outward from the site 12 with reference to FIG. 1. The inside is the side opposite to the outside. Left and right refer to the left and right when the lattice fence 10 is viewed from the inside. In the following description, the same members are basically given the same reference numerals, and repeated descriptions are omitted. In the present embodiment, the lattice fence 10 is exemplified as a fence.

[0014] FIG. 1 is a plan view showing a site or the like provided with the lattice fence 10. Here, a site 12 on which a house 13 is built is shown. A house 13 is built inside the site 12, and the lattice fence 10 is installed at a part of the outer edge of the site 12. The lattice fence 10 is installed on an installation surface 11 which is an end of the site 12. By putting the lattice fence 10 in a shielded state, the line of sight facing the house 13 from the outside can be blocked, thereby ensuring the privacy of the user living in the house 13 and improving the security of the site 12 and the house 13. Further, as will be described later, by operating the user to put the lattice fence 10 in an open state, the external scenery can be viewed through the lattice fence 10, and a certain sense of openness can be obtained. As the material of the lattice fence 10, metals such as wood, synthetic resin, iron, or composite materials thereof can be adopted.

[0015] With reference to FIGS. 2A to 3C, the configuration and the like of the lattice fence 10 according to the first embodiment will be described.

[0016] FIG. 2A is a perspective view showing the open state of the lattice fence 10 according to the first embodiment. FIG. 2B is a front view showing the open state of the lattice fence 10 according to the first embodiment. FIG. 2C is a top view showing the open state of the lattice fence 10 according to the first embodiment.

[0017] As described above, the lattice fence 10 can be in an open state and a closed state. In the open state, the gaps 25 between the fixed panels 21 are not covered by the movable lattice fence 30. In the closed state, the gaps 25 between the fixed panels 21 are covered by the movable lattice fence 30. Figure 2A and other figures show the lattice fence 10 in the open state.

[0018] The lattice fence 10 has a fixed lattice fence 20, a movable lattice fence 30, and a panel movement mechanism 40. The lattice fence 10 is installed on the installation surface 11 of the site 12 described above, and when in a shielded state, blocks views from the outside, and when in an open state, ensures good visibility from the inside. One example of the lattice fence 10 is a 1000-bar lattice fence. By attaching the fixed lattice fence 20 and the movable lattice fence 30 to the 1000-bar lattice fence 10, the privacy and safety of the 1000-bar lattice fence 10 can be improved.

[0019] The fixed grating 20 has a plurality of fixed panels 21 arranged at intervals along the width direction. The fixed grating 20 has a plurality of fixed panels 21 arranged along the left - right direction that do not move in the open state and the shielding state. The fixed panel 21 is a plate having a longitudinal direction along the up - down direction. The fixed panels 21 are spaced at substantially equal intervals, and a gap 25 is formed between the fixed panels 21. The fixed panels 21 are connected by a fixed - panel connecting portion 26. The fixed - panel connecting portion 26 is a long member extending along the left - right direction. Two fixed - panel connecting portions 26 are arranged near the upper - end portion and the lower - end portion of the fixed panel 21. The fixed - panel connecting portion 26 is fixed to the inner surface of the fixed panel 21. For the connection between the fixed - panel connecting portion 26 and the fixed panel 21, a connection structure using nails, bolts, adhesives, etc. can be adopted. Such a connection structure is the same for the connection points of other members. By connecting the plurality of fixed panels 21 by the fixed - panel connecting portion 26, the fixed grating 20 in a substantially plate - like shape as a whole is assembled. Columns 23 are arranged at both ends of the fixed grating 20 in the left - right direction. The column 23, like the fixed panel 21, has its middle portion supported by the fixed - panel connecting portion 26. Also, the column 23 extends downward more than the fixed panel 21. Therefore, by embedding the vicinity of the lower - end portion of the columns 23 arranged at both ends of the fixed grating 20 into the installation surface 11 of the site 12 shown in FIG. 1, the grating 10 including the fixed grating 20 can be fixed to the installation surface 11.

[0020] The movable grating 30 has movable panels 31 arranged at intervals along the width direction. The movable grating 30 has a plurality of movable panels 31 that move in the open state and the shielding state. The movable grating 30 is a grating configured to be displaceable along the left - right direction with respect to the fixed grating 20. The movable grating 30 is a shielding member that closes the gap 25 as needed. The movable grating 30 mainly includes a movable panel 31 and a movable - panel connecting portion 32.

[0021] The movable panels 31 are plates arranged at predetermined intervals in the left-right direction and have a longitudinal direction along the up-down direction. The material of the movable lattice fence 30 can be an opaque material that does not allow visible light to pass through, or a translucent material that partially transmits visible light. By using a translucent material for the movable lattice fence 30, light can be let in from outside even when the lattice fence 10 is in the shielding state.

[0022] The movable panel connector 32 extends horizontally to connect the movable panels 31 to each other. The movable panel connector 32 is a member that connects the movable panels 31 near their upper ends. The movable panel connector 32 is a plate-shaped member having a longitudinal direction along the left-right direction. Here, the movable panel connector 32 is installed on the outer surface of the movable panel 31. That is, the movable panel connector 32 is disposed between the fixed panel 21 and the movable panel 31. The right end of the movable panel connector 32 protrudes to the right to form a movable panel grip 35. The movable panel grip 35 is a portion that a user grasps to transition the state of the lattice fence 10 between the closed state and the open state. As described below, when a user holds the movable panel grip 35 and moves the fixed lattice fence 20 to the right, the lattice fence 10 transitions from the open state to the closed state. Conversely, when the user holds the movable panel grip portion 35 and moves the fixed lattice fence 20 to the left, the lattice fence 10 transitions from the closed state to the open state.

[0023] The panel movement mechanism 40 is a mechanism configured to be able to move the movable panels 31 while maintaining the spacing between the movable panels 31 when transitioning from the open state to the shielded state, or from the open state to the shielded state. The panel movement mechanism 40 is configured to be able to move the movable lattice fence 30 along the width direction.

[0024] Here, the panel moving mechanism 40 has a slit 41 and a movable lattice fence mounting portion 22.

[0025] The slit 41 is a notch formed in the movable lattice fence 30 and having a longitudinal direction along the left - right direction. The slit 41 is formed from the rear surface of the movable panel connecting portion 32.

[0026] The movable lattice fence mounting portion 22 is a portion formed in the fixed lattice fence 20, protruding inward, and inserted into the slit 41. Inside the slit 41, the movable lattice fence mounting portion 22 is slidable along the left - right direction. Thereby, the movable panel 31 is slidable with respect to the fixed panel 21.

[0027] The lattice fence 10 shown in FIG. 2A etc. is in an open state, and the gap 25 of the fixed lattice fence 20 is not shielded by the movable panel 31 of the movable lattice fence 30. That is, when looking at the lattice fence 10 from the inside, the fixed panel 21 of the fixed lattice fence 20 and the movable panel 31 of the movable lattice fence 30 overlap. Thereby, a view from the inside to the outside is secured via the gap 25, and the user can view the outside scenery.

[0028] FIG. 3A is a perspective view showing the shielding state of the lattice fence 10 according to the first embodiment. FIG. 3B is a front view showing the shielding state of the lattice fence 10 according to the first embodiment. FIG. 3C is a top view showing the shielding state of the lattice fence 10 according to the first embodiment.

[0029] To change the lattice fence 10 from the open state shown in FIG. 2A etc. to the shielding state shown in FIG. 3A etc., the user slides the movable panel gripping portion 35 in the right direction. Thereby, the gap 25 between the fixed panels 21 can be blocked by the moved movable panel 31. At this time, as shown in FIG. 2B, the movable lattice fence mounting portion 22 is disposed at the left end inside the slit 41. Therefore, the line of sight through the gap 25 of the movable panel 31 can be appropriately blocked by the fixed panel 21, and privacy protection and security improvement can be achieved.

[0030] When transitioning from the shielded state to the open state, the user grips the movable panel gripping portion 35 and moves the movable lattice grid 30 toward the left. As a result, the open state shown in FIG. 2B is achieved, and the view through the gap 25 is secured again.

[0031] Referring to FIG. 2A, the lattice grid 10 according to the present embodiment does not have an outer frame that surrounds the whole from the outside. Therefore, the lattice grid 10 can reduce the manufacturing cost, improve the degree of freedom in design, and also improve the usability when used by the user.

[0032] Referring to FIGS. 4A to 6B, the configuration and the like of the lattice grid 10 according to the second embodiment will be described. In the lattice grid 10 according to the second embodiment, the movable panel 31 is a rotary type that rotates 90 degrees, and other matters are the same as those in the first embodiment. Here, the above-described movable panel connecting portion 32 is a shaft connecting portion 44. The same applies to the forms from the third embodiment onward.

[0033] FIG. 4A is a front view showing the open state of the lattice grid 10 according to the second embodiment. FIG. 4B is a perspective view showing the open state of the lattice grid 10 according to the second embodiment. FIG. 4C is a top view showing the open state of the lattice grid 10 according to the second embodiment.

[0034] Referring to FIG. 4C, the movable panel 31 is rotatable and has a first end portion 33 that is one end side in the width direction and a second end portion 34 that is the other end side in the width direction. In the open state, the maximum surface of the movable panel 31 is substantially perpendicular to the direction in which the shaft connecting portion 44 described later extends, and is in close contact with the fixed panel 21. Then, the movable panel 31 is housed in a recessed portion that depresses the right side surface of the fixed panel 21 toward the left. As a result, the movable panel 31 does not block the gap 25 in the open state.

[0035] Referring to FIG. 4B, the panel moving mechanism 40 has a shaft connecting portion 44 and a rotating shaft portion 43. The shaft connecting portion 44 is a substantially rod-shaped member and is disposed on the lower side of the fixed panel 21. The shaft connecting portion 44 extends substantially linearly from the left end to the right end of the lattice fence 10. As shown in FIG. 4B, the rotating shaft portion 43 extends upward from the shaft connecting portion 44. The rotating shaft portion 43 is rotatably connected to the second end portion 34 shown in FIG. 4C.

[0036] The movable panel gripping portion 35 is a substantially rod-shaped member that extends upward from the right end side, which is the widthwise end portion of the shaft connecting portion 44. With such a configuration in which the movable panel gripping portion 35 engages, the user can transition the lattice fence 10 between the open state and the shielding state by a simple operation of moving the movable panel gripping portion 35 left and right. Further, the user can operate the movable panel gripping portion 35 without bending down.

[0037] The first end portion 33 of the movable panel 31 is rotatably supported with respect to the fixed panel 21 of the fixed lattice fence 20. Referring to FIG. 4B, the first end portion 33 is formed at the upper end portion and the lower end portion of the movable panel 31.

[0038] The side of the second end portion 34 of the movable panel 31 is connected to the shaft connecting portion 44 via the rotating shaft portion 43 as described above. Further, the second end portion 34 of the movable panel 31 is rotatably connected to the movable panel gripping portion 35.

[0039] Here, the shaft connecting portion 44 and the rotating shaft portion 43 can also be disposed on the upper side of the fixed panel 21. In such a case, the rotating shaft portion 43 is connected to the second end portion 34 at the upper end of the movable panel 31. The shaft connecting portion 44 extends from the left end portion to the right end portion of the fixed lattice fence 20 on the upper side of the fixed panel 21. The movable panel gripping portion 35 extends downward from the right end portion of the shaft connecting portion 44.

[0040] FIG. 5A is a perspective view showing an intermediate state of the lattice fence 10 according to the second embodiment. FIG. 5B is a top view showing an intermediate state of the lattice fence 10 according to the second embodiment.

[0041] Referring to FIGS. 5A and 5B , when the user grasps the movable panel gripping portion 35 and pulls it to the right, an intermediate state between the open state and the closed state is realized. Specifically, when the user grasps the movable panel gripping portion 35 and moves it to the right, as shown in FIG. 5B , the second end 34 of the movable panel 31 is pulled to the right via the pivot coupling portion 44 and the rotational shaft portion 43. This causes the movable panel 31 to rotate counterclockwise around the first end 33. When the user further moves the movable panel gripping portion 35 to the right from the state shown in FIG. 5B , the closed state, which will be described later, is achieved. At this time, as shown in FIG. 5A , the pivot coupling portion 44 is positioned below the lower end of the fixed panel 21, and therefore the pivot coupling portion 44 can move below the fixed panel 21. Therefore, the movement of the pivot coupling portion 44 is not hindered by the fixed panel 21.

[0042] Fig. 6A is a perspective view showing the shielding state of the lattice fence 10 according to the second embodiment. Fig. 6B is a top view showing the shielding state of the lattice fence 10 according to the second embodiment.

[0043] 6B, in the shielding state, the movable panel 31 is approximately parallel to the direction in which the movable panel gripping portion 35 extends, and moves away from the fixed panel 21 to close the gap 25.

[0044] Specifically, when the user pulls the movable panel gripping portion 35 further to the right, the second end portion 34 of the movable panel 31 is pulled further to the right via the shaft connecting portion 44 and the rotation shaft portion 43. This causes the movable panel 31 to rotate further counterclockwise around the first end portion 33 as the rotation center. Compared to the open state, the movable panel 31 has rotated 90 degrees. As a result, the gap 25 is blocked by the movable panel 31, and the shielded state is achieved.

[0045] Here, the movable panel 31 can be easily switched between the open state and the closed state by rotating it through the operation of the movable panel gripping portion 35. In the open state shown in Fig. 4C etc., the movable panel 31 is approximately perpendicular to the direction in which the shaft connecting portion 44 extends and is in close contact with the fixed panel 21. On the other hand, in the closed state shown in Fig. 6B, the movable panel 31 is approximately parallel to the direction in which the movable panel gripping portion 35 extends and is separated from the fixed panel 21, thereby closing the gap 25.

[0046] The configuration of the lattice fence 10 according to the third embodiment will be described with reference to Figures 7A to 9B. The lattice fence 10 according to the third embodiment is a rotatable type in which the movable panel 31 rotates 180 degrees, but other details are the same as those of the first embodiment.

[0047] Figure 7A is a front view showing the lattice fence 10 according to the third embodiment in an open state, Figure 7B is a perspective view showing the lattice fence 10 according to the third embodiment in an open state, and Figure 7C is a top view showing the lattice fence 10 according to the third embodiment in an open state.

[0048] 7C, in the open state, the movable panel 31 is approximately parallel to the direction in which the shaft connecting portion 44 extends, and is in close contact with the inner side surface of the fixed panel 21. In other words, the movable panel 31 and the fixed panel 21 are in an overlapping state, and the movable panel 31 does not block the gap 25. This ensures visibility through the gap 25.

[0049] The movable panel 31 has a first end 33 and a second end 34. The first end 33 is the right end of the movable panel 31. The first end 33 of the movable panel 31 is rotatably connected to the right end of the fixed panel 21. The second end 34 is the left end of the movable panel 31 and is rotatably connected to the shaft coupling portion 44 via the rotation shaft portion 43.

[0050] The configurations of the rotary shaft portion 43, the shaft connecting portion 44, and the movable panel gripping portion 35 are substantially the same as those in the second embodiment described above.

[0051] FIG. 8A is a perspective view showing an intermediate state of the lattice fence 10 according to the third embodiment. FIG. 8B is a top view showing an intermediate state of the lattice fence 10 according to the third embodiment.

[0052] When the user pulls the movable panel gripping portion 35 rightward, the second end portion 34 of the movable panel 31 is also pulled rightward via the shaft connecting portion 44 and the rotary shaft portion 43. Then, the movable panel 31 rotates counterclockwise about the first end portion 33 as the rotation center. Here, a state where the movable panel 31 is rotated by about 90 degrees is shown.

[0053] FIG. 9A is a perspective view showing a shielding state of the lattice fence 10 according to the third embodiment. FIG. 9B is a top view showing a shielding state of the lattice fence 10 according to the third embodiment.

[0054] Referring to FIGS. 9A and 9B, when the user further pulls the movable panel gripping portion 35 rightward, the movable panel 31 further rotates to close the gap 25. Here, a shielding state where the movable panel 31 is rotated 180 degrees about the first end portion 33 as the rotation center is shown. In the shielding state, the movable panel 31 is substantially parallel to the direction in which the shaft connecting portion 44 extends. Further, the movable panel 31 moves away from the inner side surface of the fixed panel 21 and closes the gap 25.

[0055] Here, as shown in FIG. 7C, in the open state, the movable panel 31 overlaps with the fixed panel 21, so that the movable panel 31 does not close the gap 25 between the fixed panels 21. On the other hand, in the shielding state shown in FIG. 9B, the movable panel 31 is configured to close the gap 25 between the fixed panels 21. Further, the movable panel gripping portion 35 is a shaft connecting portion 44 connected to the second end portion 34 of the movable panel 31. Further, the shaft connecting portion 44 is disposed below the fixed panel 21. Therefore, since the shaft connecting portion 44 is disposed below the fixed panel 21, the displacement of the shaft connecting portion 44 is not inhibited by the fixed panel 21.

[0056] The configuration of a lattice fence 10 according to the fourth embodiment will be described with reference to Figures 10A to 11C. The lattice fence 10 according to the fourth embodiment is equipped with a movement restriction section 50 as the panel movement mechanism 40. Furthermore, the lattice fence 10 according to the fourth embodiment differs from the previously described embodiments in the way the movable panels 31 are stored. Other details are the same as those of the first embodiment, etc.

[0057] FIG. 10A is a front view showing the open state of the lattice fence 10 according to the fourth embodiment. FIG. 10B is a top view showing the open state of the lattice fence 10 according to the fourth embodiment. FIG. 10C is a perspective view showing the open state of the movement restricting unit 50 according to the fourth embodiment. Here, the panel moving mechanism 40 includes a panel biasing section 42 and a movement restricting section 50 .

[0058] Generally speaking, the lattice fence 10 here has a panel storage section 45 formed in each fixed panel 21, and a movable panel 31 is stored in the panel storage section 45. In addition, a movement restriction section 50 controls the advance and retreat of the movable panel 31.

[0059] The panel storage section 45 is a cavity formed in the fixed panel 21 and opens to the right. The panel storage section 45 has a size that allows the movable panel 31 to be stored therein.

[0060] The movable panel 31 is stored in the panel storage section 45 of each fixed panel 21 so that it can move forward and backward in the width direction. As will be described later, when the movable panel 31 is stored in the panel storage section 45, the lattice fence 10 is in an open state. On the other hand, when the movable panel 31 protrudes to the right from the panel storage section 45, the lattice fence 10 is in a closed state.

[0061] The panel biasing portion 42 is built into the panel storage portion 45 and is configured to bias the movable panel 31 outward in the width direction. Any elastic body, such as a coil spring, can be used as the panel biasing portion 42. The panel biasing portion 42 is located at the left end of the panel storage portion 45 and biases the movable panel 31 toward the right.

[0062] Referring to FIG. 10C, the movement restricting unit 50 is configured to restrict the movement of the movable panel 31 from the panel storage unit 45. As will be described later, the movement restricting unit 50 restricts the protrusion of the movable panel 31 in the open state and does not restrict the protrusion of the movable panel 31 in the shielded state. Specifically, the movement restricting unit 50 includes a restricting connection part 51, a panel movement restricting part 52, and a restricting contact part 53.

[0063] The restricting connection part 51 is a long member extending along the width direction. As the restricting connection part 51, a substantially rod-shaped member can be adopted. The restricting connection part 51 extends linearly from the vicinity of the left end portion to the vicinity of the right end portion of the lattice fence 10. The restricting connection part 51 is rotatably supported by the fixed panel 21.

[0064] The panel movement restricting part 52 is connected to the restricting connection part 51 and is configured to restrict the movement of the movable panel 31 outward in the width direction by contacting the movable panel 31. As shown in FIG. 10C, the panel movement restricting part 52 is a substantially disk-shaped portion fixed to the restricting connection part 51. Also, as shown in FIG. 10B, the panel movement restricting part 52 is provided corresponding to each movable panel 31. As will be described later, the panel movement restricting part 52 contacts the right end portion of the movable panel 31 in both the open state and the shielded state.

[0065] The restricting contact part 53 is connected to the restricting connection part 51 and is configured to appropriately contact the fixed lattice fence 20. The shape of the restricting contact part 53 is different from that of the panel movement restricting part 52. The shape of the restricting contact part 53 is, for example, a substantially circular shape with a part cut out. The restricting contact part 53 contacts the left end portion of the fixed panel 21 in the open state. Also, the restricting contact part 53 does not contact the left end portion of the fixed panel 21 in the shielded state. The restricting contact part 53 can take a contact state of contacting the left side surface of the fixed panel 21 and a non-contact state of not contacting the left side surface of the fixed panel 21 by rotating.

[0066] In the open state, the restricting abutment portion 53 abuts against the fixed lattice fence 20, thereby fixing the position of the panel movement restricting portion 52 via the restricting connection portion 51. Specifically, as shown in FIG. 10C , the notch of the restricting abutment portion 53 is located on the outside, and the inner portion of the restricting abutment portion 53 is substantially circular. Therefore, as shown in FIG. 10B , the restricting abutment portion 53 of the movement restricting portion 50 abuts against the left side surface of the fixed panel 21 located on the leftmost side. This fixes the position of the panel movement restricting portion 52 in the left-right direction via the restricting connection portion 51. Specifically, the panel movement restricting portion 52 is located immediately adjacent to the right side surface of the fixed panel 21. Therefore, the panel movement restricting portion 52 presses down on the right end portion of the restricting connection portion 51 stored in the panel storage portion 45. As a result, the panel movement restricting portion 52 presses down on the movable panel 31 even when the movable panel 31 is biased rightward by the panel biasing portion 42. Therefore, the movable panel 31 does not protrude toward the panel movement restricting portion 52. This ensures visibility through the gap 25 in the open state.

[0067] In the open state, the movement restricting portion 50 is rotated to move the notch of the restricting contact portion 53 inward, thereby achieving the closed state described below.

[0068] Figure 11A is a front view showing the shielding state of the lattice fence 10 according to the fourth embodiment, Figure 11B is a top view showing the shielding state of the lattice fence 10 according to the fourth embodiment, and Figure 11C is a perspective view showing the shielding state of the movement restricting section 50 according to the fourth embodiment.

[0069] 11C, the user rotates the restricting contact portion 53, thereby positioning the notch of the restricting contact portion 53 inward. Here, the rotation of the restricting contact portion 53 may involve rotating only the restricting contact portion 53, or the entire movement restricting portion 50.

[0070] Referring to FIG. 11B , by arranging the notch of the restricting abutment portion 53 on the inside, the restricting abutment portion 53 does not abut against the left side surface of the fixed panel 21. In other words, the position of the panel movement restricting portion 52 is not fixed. Meanwhile, the panel biasing portion 42 built into each fixed panel 21 biases the movable panel 31 and the panel movement restricting portion 52 toward the right, which is the outer side in the width direction. This causes each movable panel 31 and panel movement restricting portion 52 to move toward the right. As a result, the panel movement restricting portion 52 abuts against the right side surface of the fixed panel 21. This causes the movable panel 31 to move toward the right from the fixed panel 21, shielding the panel movement restricting portion 52. This achieves the shielding state of the lattice fence 10.

[0071] To transition from the closed state to the open state, the user pushes back the movement restricting part 50 to the left, rotates the restricting contact part 53, and engages the restricting contact part 53 with the left side surface of the fixed panel 21. This returns to the state shown in Fig. 10A etc., i.e., the movable panel 31 is stored inside the fixed panel 21, and the lattice fence 10 is in the open state.

[0072] Here, in the open state, the movement of the movable panel 31 is restricted by the movement restricting portion 50, thereby maintaining the stored state. On the other hand, in the closed state, the restriction is released by rotating the movement restricting portion 50, and the biasing force of the panel biasing portion 42 causes the movable panel 31 to protrude outward in the width direction from the panel storage portion 45 of the fixed panel 21, allowing the movable panel 31 to fill the gap 25 between the fixed panels 21.

[0073] The configuration of the lattice fence 10 according to the fifth embodiment will be described with reference to Figures 12A and 12B. In the lattice fence 10 according to the fifth embodiment, the movable panel 31 includes a first movable panel 311 and a second movable panel 312, and other details are the same as in the fourth embodiment.

[0074] Fig. 12A is a top view showing the lattice fence 10 according to the fifth embodiment in an open state. Fig. 12B is a top view showing the movement restricting section 50 according to the fifth embodiment in a closed state.

[0075] Referring to FIG. 12A, the movable panel 31 has a first movable panel 311 and a second movable panel 312. Both the first movable panel 311 and the second movable panel 312 are housed in the fixed panel 21. The first movable panel 311 and the second movable panel 312 are arranged to overlap inside the fixed panel 21. Further, the first movable panel 311 and the second movable panel 312 are connected via a connecting portion 36. The connecting portion 36 is a connecting portion that slidably connects the first movable panel 311 and the second movable panel 312. The panel biasing portion 42 biases the first movable panel 311 toward the right inside the fixed panel 21. In the open state shown in FIG. 12A, the restricting contact portion 53 abuts against the left side surface of the fixed panel 21, so that in each fixed panel 21, the panel movement restricting portion 52 presses the first movable panel 311 and the second movable panel 312.

[0076] Referring to FIG. 12B, when the restricting contact portion 53 rotates and the engagement between the left side surface of the fixed panel 21 and the restricting contact portion 53 is disengaged, the movement restricting portion 50 including the panel movement restricting portion 52 moves toward the right by the biasing force of the panel biasing portion 42. Then, the first movable panel 311 and the second movable panel 312 protrude rightward from inside the fixed panel 21 and close the gap 25. As a result, the gap 25 is in a shielded state blocked by the first movable panel 311 and the second movable panel 312.

[0077] To transition from the shielded state to the open state, the user pushes the movement restricting portion 50 back to the left, rotates the restricting contact portion 53, and engages the restricting contact portion 53 with the left side surface of the fixed panel 21. Thereby, it returns to the state shown in FIG. 12A, that is, the first movable panel 311 and the second movable panel 312 are housed inside the fixed panel 21, and the lattice fence 10 is in an open state.

[0078] Here, since the movable panel 31 is composed of the first movable panel 311 and the second movable panel 312, the width of the fixed panel 21 can be narrowed.

[0079] Referring to FIGS. 13A to 13C, the configuration of the grating 10 according to the sixth embodiment will be described. FIG. 13A is a front view showing the open state of the grating 10 according to the sixth embodiment. FIG. 13B is a perspective view showing the open state of the grating 10 according to the sixth embodiment. FIG. 13C is a top view showing the open state of the grating 10 according to the sixth embodiment.

[0080] The basic configuration and operation of the grating 10 according to the sixth embodiment, such as the configuration, are the same as those of the grating 10 according to the third embodiment shown in FIGS. 7A and the like. Therefore, the description will focus on the differences, and the description of the common configurations and the like will be omitted and incorporated by reference.

[0081] Here, the movable panel gripping portion 35 is provided at an intermediate portion of the shaft connecting portion 44 in the width direction. As an example, the movable panel gripping portion 35 is disposed at a substantially central portion in the width direction. Specifically, the shaft connecting portion 44 is disposed below the fixed panel 21 and the movable panel 31, and the movable panel gripping portion 35 is a rod-shaped member extending upward from a substantially central portion of the shaft connecting portion 44.

[0082] When the user performs the opening and closing operation of the movable panel 31, the operation is performed by gripping the movable panel gripping portion 35. Since the movable panel gripping portion 35 is disposed at a substantially central portion of the shaft connecting portion 44, each movable panel 31 can be smoothly rotated via the movable panel gripping portion 35 and the shaft connecting portion 44.

[0083] Here, referring to FIG. 13C, the movable panel gripping portion 35 may be disposed inside the fixed panel connecting portion 26. In this case, the movable panel gripping portion 35 extends from a substantially central portion of the shaft connecting portion 44 in the width direction, passes through the lower portions of the shaft connecting portion 44 and the fixed panel connecting portion 26, extends inside the fixed panel connecting portion 26, and further extends upward. By doing so, the user can rotate the movable panel 31 in both directions by operating the movable panel gripping portion 35 existing inside the fixed panel connecting portion 26.

[0084] The configuration of the lattice fence 10 according to the seventh embodiment will be described with reference to Figures 14A to 14C. Figure 14A is a perspective view showing the lattice fence 10 according to the seventh embodiment in an open state. Figure 14B is a top view showing the lattice fence 10 according to the seventh embodiment in an open state. Figure 14C is a side view showing the lattice fence 10 according to the seventh embodiment in an open state.

[0085] The basic configuration and operation of the lattice fence 10 according to the seventh embodiment are the same as those of the lattice fence 10 according to the third embodiment shown in Figure 7A, etc., so the following explanation will focus on the differences, and explanations of the common configurations, etc. will be omitted and used by reference.

[0086] 14A and 14B, the movable panel gripping portion 35 is fixed to the outer surface of the movable panel 31, not to the pivot connecting portion 44. As shown in FIG. 14C, the movable panel gripping portion 35 has a shape similar to a general handle. The movable panel gripping portion 35 is disposed in the middle portion, preferably the center portion, of the movable panel 31 in the up-down direction. The movable panel gripping portion 35 is also disposed on the movable panel 31 that is disposed in the middle portion or approximately the center portion in the left-right direction. This allows the movable panel 31 to rotate smoothly via the pivot connecting portion 44.

[0087] The configuration of a lattice fence 10 according to an eighth embodiment will be described with reference to FIGS. 15A to 16C.

[0088] Figure 15A is a front view showing the lattice fence 10 according to the eighth embodiment in an open state, Figure 15B is a perspective view showing the lattice fence 10 according to the eighth embodiment in an open state, and Figure 15C is a top view showing the lattice fence 10 according to the eighth embodiment in an open state.

[0089] The basic configuration and operation of the lattice grid 10 according to the eighth embodiment, such as the configuration, are the same as those of the lattice grid 10 according to the first embodiment shown in FIG. 2A and the like. Therefore, the description will focus on the differences, and the description of the common configurations and the like will be omitted and incorporated by reference. In FIGS. 15B and 15C, the movable panel connecting portion 32 is not shown in order to clearly show the rail mechanism 37. In the actual lattice grid 10, the movable panel connecting portion 32 commonly fixes the inner surface or the outer surface of the movable panel 31.

[0090] Referring to FIGS. 15B and 15C, a rail mechanism 37 is disposed between the fixed panel 21 and the movable panel 31. The rail mechanism 37 is disposed between the inner surface of the fixed panel 21 and the outer surface of the movable panel 31. The rail mechanism 37 has a rail portion extending in the left-right direction and a rail receiving portion that supports the rail portion so as to be movable along the left-right direction. One of the rail portion and the rail receiving portion is installed on the inner surface of the fixed panel 21, and the other is disposed on the outer surface of the movable panel 31. The rail mechanism 37 is disposed for each combination of the fixed panel 21 and the movable panel 31. The rail mechanism 37 may be disposed only at the upper part of the lattice grid 10, may be disposed only at the lower part, or may be disposed at both the upper and lower parts.

[0091] FIG. 16A is a front view showing the shielding state of the lattice grid 10 according to the eighth embodiment. FIG. 16B is a perspective view showing the shielding state of the lattice grid 10 according to the eighth embodiment. FIG. 16C is a top view showing the shielding state of the lattice grid 10 according to the eighth embodiment.

[0092] Referring to FIGS. 16B and 16C, when the user operates the movable panel gripping portion 35 toward the right, the movable lattice grid 30 moves toward the right, and the movable panel 31 is disposed at a position where it closes the gap 25. With such a configuration, it is possible to block the line of sight from the outside through the gap 25. In the shielding state, the rail mechanism 37 guides and holds the rightward movement of the movable panel 31. Conversely, when shifting from the shielding state to the open state, the user pushes the movable panel gripping portion 35 toward the left, thereby displacing the movable panel 31 guided by the rail mechanism 37 toward the left.

[0093] 15C, the outer surface of the movable panel 31 can be tightly fitted to the inner surface of the fixed panel 21. Such a tight fitting configuration can be achieved, for example, by accommodating the rail portion and rail receiving portion that make up the rail mechanism 37 within the thickness portions of the fixed panel 21 and the movable panel 31.

[0094] Furthermore, a stopper for controlling the amount of movement of the movable panel 31 in the left-right direction can be provided on the rail mechanism 37. Such a stopper can prevent the movable panel 31 from moving excessively leftward and in the A direction.

[0095] The configuration and operation of the lattice fence 10 according to the ninth embodiment will be described with reference to Figures 17A to 19B. The configuration and operation of the lattice fence 10 according to the ninth embodiment are essentially the same as the configuration and operation of the lattice fence 10 according to the second embodiment described above with reference to Figure 5A etc., except that the first end 33 is located on the inside and the second end 34 is located on the outside.

[0096] Figure 17A is a front view showing the lattice fence 10 according to the ninth embodiment in an open state, Figure 17B is a perspective view showing the lattice fence 10 according to the ninth embodiment in an open state, and Figure 17C is a top view showing the lattice fence 10 according to the ninth embodiment in an open state.

[0097] 17C, the movable panel 31 is rotatable and has a first end 33 disposed on the inside and a second end 34 disposed on the outside. In the open state, the largest surface of the movable panel 31 is approximately perpendicular to the direction in which a shaft connecting portion 44 (described later) extends, and is in close contact with the fixed panel 21. The movable panel 31 is stored in a recess formed by recessing the right side surface of the fixed panel 21 toward the left. As a result, the movable panel 31 does not block the gap 25 in the open state.

[0098] Referring to FIG. 17B, the panel moving mechanism 40 has a shaft connecting portion 44 and a rotating shaft portion 43. The shaft connecting portion 44 is a substantially rod-shaped member and is disposed below the fixed panel 21. The shaft connecting portion 44 extends substantially linearly from the left end to the right end of the lattice fence 10. As shown in FIG. 17B, the rotating shaft portion 43 extends upward from the shaft connecting portion 44. The rotating shaft portion 43 is rotatably connected to the second end portion 34 shown in FIG. 17C.

[0099] The movable panel gripping portion 35 is a substantially rod-shaped member that extends upward from the right end side, which is the widthwise end portion of the shaft connecting portion 44. With such a configuration that the movable panel gripping portion 35 is engaged, the user can transition the lattice fence 10 between the open state and the shielding state by a simple operation of moving the movable panel gripping portion 35 left and right. Further, the user can operate the movable panel gripping portion 35 without bending down.

[0100] The first end portion 33 of the movable panel 31 is rotatably supported with respect to the fixed panel 21 of the fixed lattice fence 20. Referring to FIG. 17B, the first end portion 33 is formed at the upper end portion and the lower end portion of the movable panel 31. As shown in FIG. 17C, the first end portion 33 is rotatably connected inside the right side surface of the fixed panel 21.

[0101] FIG. 18A is a perspective view showing an intermediate state of the lattice fence 10 according to the ninth embodiment. FIG. 18B is a top view showing an intermediate state of the lattice fence 10 according to the ninth embodiment.

[0102] Referring to FIGS. 18A and 18B, when the user grips the movable panel gripping portion 35 and pulls it to the right, an intermediate state, which is an intermediate state between the open state and the shielding state, is realized. Specifically, when the user grips the movable panel gripping portion 35 and moves it toward the right side, referring to FIG. 18B, the second end portion 34 of the movable panel 31 is pulled toward the right through the shaft connecting portion 44 and the rotating shaft portion 43. Then, the movable panel 31 rotates clockwise with the first end portion 33 as the rotation center. When the user further moves the movable panel gripping portion 35 further to the right from the state shown in FIG. 18B, the shielding state described later is obtained.

[0103] FIG. 19A is a perspective view showing the shielding state of the lattice grid 10 according to the ninth embodiment. FIG. 19B is a top view showing the shielding state of the lattice grid 10 according to the ninth embodiment.

[0104] Referring to FIG. 19B, in the shielding state, the movable panel 31 is substantially parallel to the direction in which the movable panel gripping portion 35 extends, and closes the gap 25 by moving away from the fixed panel 21.

[0105] Specifically, when the user further pulls the movable panel gripping portion 35 rightward, the second end portion 34 of the movable panel 31 is further pulled rightward via the shaft connecting portion 44 and the rotating shaft portion 43. As a result, the movable panel 31 rotates further clockwise with the first end portion 33 as the rotation center. Compared with the open state, the movable panel 31 has rotated 90 degrees. Thereby, the gap 25 is blocked by the movable panel 31, and the shielding state is realized.

[0106] As described above, the embodiments of the present invention have been described. However, the present invention is not limited thereto, and can be modified without departing from the gist of the present invention. Also, the above-described embodiments can be combined with each other.

[0107] For example, referring to FIG. 1, the lattice grid 10 includes a fixed lattice grid 20, a movable lattice grid 30, and a panel moving mechanism 40. However, a mechanism including the movable lattice grid 30 and the panel moving mechanism 40 can also be configured as a movable grid module. In this case, by attaching the movable grid module to the existing lattice grid 10, the privacy and safety of the existing lattice grid 10 can be improved.

[0108] Also, in all of the above-described embodiments, particularly in the second and fifth embodiments, in the left-right direction, the width of the gap 25 may be shorter or longer than the width of the fixed panel 21. By making the width of the gap 25 shorter than the width of the fixed panel 21, the effect of blocking the view from the outside can be made remarkable. On the other hand, even when the width of the gap 25 is wide, a complete shielding state can be created by filling the gap 25 with the fixed panel 21.

[0109] Furthermore, advertisements or the like can also be displayed on the movable panel 31 described above. For example, referring to FIG. 9B and the like, advertisements, predetermined patterns, logo marks, etc. can also be displayed on the surfaces facing the outside of the fixed panel 21 and the movable panel 31. By doing so, advertisements or the like can be displayed on the outside of the movable panel 31 in the shielding state of the lattice fence 10, improving the appearance design of the lattice fence 10, and the lattice fence 10 can also be utilized in stores or the like.

[0110] Furthermore, the configuration of the slit 41 and the movable lattice fence attachment portion 22 shown in the second embodiment shown in FIGS. 2A to 3C, and further, the rail mechanism 37 shown in FIGS. 16B and the like can also be adopted for the lattice fence 10 of the fourth embodiment shown in FIGS. 10A to 11C.

[0111] Furthermore, in each of the above-described embodiments, the lattice fence 10 can also be used for applications installed outside the site 12. For example, the lattice fence 10 can also be installed on the window of the house 13. That is, the lattice fence 10 can also be used as a window lattice.

[0112] Furthermore, in all of the embodiments, the positional relationship between the fixed panel 21 and the movable panel 31 can be interchanged. For example, referring to FIG. 2C, the fixed panel 21 can be arranged inside and the movable panel 31 can be arranged outside.

[0113] The invention understood from the above-described embodiments will be described below together with its effects.

[0114] The grid fence according to an embodiment of the present invention includes a fixed grid fence fixed to an installation surface, a movable grid fence configured to be displaceable relative to the fixed grid fence, and a panel moving mechanism that moves the movable grid fence along the width direction. The gap of the fixed grid fence can be in an open state not covered by the movable grid fence and a shielded state covered by the movable grid fence. The fixed grid fence has a plurality of fixed panels that are spaced apart along the width direction and do not move in the open state and the shielded state. The movable grid fence has a plurality of movable panels that are spaced apart along the width direction and move in the open state and the shielded state. The panel moving mechanism is configured to be able to move the movable panels while maintaining the interval between the movable panels. According to the grid fence of the present invention, by moving the movable panels of the movable grid fence in the width direction by the panel moving mechanism, the gap between the fixed panels can be blocked by the movable panels. Therefore, the line of sight through the gap of the fixed panels can be appropriately blocked by the movable panels, and privacy protection and security improvement can be achieved.

[0115] Further, in the grid fence according to an embodiment of the present invention, the movable grid fence further has a movable panel connecting portion that extends in the lateral direction so as to connect the movable panels. The panel moving mechanism has a slit formed in the movable grid fence and a movable grid fence mounting portion formed in the fixed grid fence and inserted into the slit. Inside the slit, the movable grid fence mounting portion is slidable. According to the grid fence of the present invention, since the movable panel is slidable relative to the fixed panel, for example, by the user sliding the movable panel connecting portion in the lateral direction, the gap between the fixed panels can be blocked by the movable panels.

[0116] Further, in the lattice fence according to the embodiment of the present invention, in the panel movement mechanism, a first end portion in the width direction of the movable panel is rotatably supported with respect to the fixed lattice fence, and a side of a second end portion in the width direction of the movable panel is rotatably connected to the movable panel connecting portion. According to the lattice fence of the present invention, by rotating the movable panel by operating the movable panel connecting portion, the open state and the shielding state can be easily switched.

[0117] Further, in the lattice fence according to the embodiment of the present invention, in the open state, the movable panel is substantially perpendicular to the direction in which the movable panel connecting portion extends, and is in close contact with the fixed panel. In the shielding state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends, and closes the gap by moving away from the fixed panel. According to the lattice fence of the present invention, in the open state, since the movable panel is in close contact with the fixed panel, the movable panel does not close the gap between the fixed panels. On the other hand, in the shielding state, the movable panel can be configured to close the gap between the fixed panels.

[0118] Further, in the lattice fence according to the embodiment of the present invention, in the open state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends, and is in close contact with the fixed panel. In the shielding state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends, and closes the gap by moving away from the fixed panel. According to the lattice fence of the present invention, in the open state, since the movable panel overlaps with the fixed panel, the movable panel does not close the gap between the fixed panels. On the other hand, in the shielding state, the movable panel can be configured to close the gap between the fixed panels.

[0119] In addition, in the lattice fence according to the embodiment of the present invention, the movable panel connecting portion is a shaft connecting portion connected to the second end portion of the movable panel, and the shaft connecting portion is disposed below or above the fixed panel. According to the lattice fence of the present invention, since the shaft connecting portion is disposed below or above the fixed panel, the displacement of the shaft connecting portion is not inhibited by the fixed panel.

[0120] In addition, in the lattice fence according to the embodiment of the present invention, the panel moving mechanism further includes a movable panel gripping portion, and the movable panel gripping portion is configured to be capable of transitioning from the open state to the shielding state by a user's operation, and is configured to extend upward from the width direction end side of the shaft connecting portion. According to the lattice fence of the present invention, the state of the movable lattice fence can be transitioned by a simple operation of the user.

[0121] In addition, in the grid fence according to the embodiment of the present invention, a panel storage portion for storing the movable panel is formed in the fixed panel. The movable panel is stored in the panel storage portion of the fixed panel so as to be able to advance and retreat along the width direction. The panel movement mechanism is built in the panel storage portion and includes a panel biasing portion that biases the movable panel outward in the width direction, and a movement restricting portion that restricts the movement of the movable panel from the panel storage portion. The movement restricting portion includes a restricting connecting portion that is a long member extending along the width direction, a panel movement restricting portion that is connected to the restricting connecting portion and restricts the outward movement of the movable panel in the width direction by contacting the movable panel, and a restricting contact portion that is connected to the restricting connecting portion and is configured to contact the fixed grid fence. In the open state, the restricting contact portion contacts the fixed grid fence, so that the position of the panel movement restricting portion is fixed via the restricting connecting portion. The panel movement restricting portion presses the movable panel, so that the movable panel is stored in the panel storage portion. In the shielding state, since the restricting contact portion does not contact the fixed grid fence, the position of the panel movement restricting portion is not fixed, and the movable panel biased by the panel biasing portion moves outward in the width direction from the panel storage portion. According to the grid fence of the present invention, in the open state, the movement restricting portion can maintain the state in which the movable panel is stored in the panel storage portion of the fixed panel. On the other hand, in the shielding state, by releasing the restriction by the movement restricting portion, the movable panel can be protruded outward in the width direction from the panel storage portion of the fixed panel by the biasing force of the panel biasing portion, and the gap between the fixed panels can be filled with the movable panel.

[0122] In addition, in the lattice fence according to the embodiment of the present invention, the restriction abutting portion can take an abutting state in which it abuts against the fixed lattice fence and a non-abutting state in which it does not abut against the fixed lattice fence, and by rotating the restriction abutting portion, the abutting state and the non-abutting state are switched. According to the lattice fence of the present invention, by a simple operation of rotating the restriction abutting portion, the abutting state and the non-abutting state between the restriction abutting portion and the fixed lattice fence can be switched, and thus the open state and the shielding state of the lattice fence can be easily switched.

A side of a first end portion of the movable panel in the width direction is rotatably supported with respect to the fixed panel. A side of a second end portion of the movable panel in the width direction is rotatably connected to the movable panel connecting portion. In the open state, the movable panel is substantially perpendicular to the direction in which the movable panel connecting portion extends and is in close contact with the fixed panel. In the shielded state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends and closes the gap by moving away from the fixed panel. A grid characterized by this. **Claim 2**: A grid includes a fixed grid fence fixed to an installation surface, a movable grid fence configured to be displaceable relative to the fixed grid fence, and a panel moving mechanism configured to move the movable grid fence along a width direction. The gap of the fixed grid fence can be in an open state where it is not covered by the movable grid fence. The gap of the fixed grid fence can be in a shielded state where it is covered by the movable grid fence. The fixed grid fence has a plurality of fixed panels that are spaced apart along the width direction and do not move in the open state and the shielded state. The movable grid fence has a plurality of movable panels that are spaced apart along the width direction and move in the open state and the shielded state. The grid further includes a movable panel connecting portion that extends along the lateral direction so as to connect the movable panels to each other. A side of a first end portion of the movable panel in the width direction is rotatably supported with respect to the fixed panel. A side of a second end portion of the movable panel in the width direction is rotatably connected to the movable panel connecting portion. In the open state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends and is in close contact with the fixed panel. In the shielding state, the movable panel is substantially parallel to the direction in which the movable panel connecting portion extends and closes a gap by being separated from the fixed panel. A fence characterized by this.
