Description

[Technical field]

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

[0002] Traditionally, lattice fences have been installed to surround gardens and houses. A lattice fence is made by assembling thin timbers vertically and horizontally, or in either direction, with gaps between them. By installing a lattice fence, it is possible to limit 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] Jpn. Jpn. Published 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] JP 2003-155847 A [Patent Document 8] No. 3233489 publication Summary of the Invention [Problem to be solved by the invention]

[0004] However, the lattice fence according to the background art has room for improvement in terms of more effectively restricting visibility from the outside.

[0005] For example, the lattice fence in the background art is composed of multiple panels arranged at a predetermined interval, with gaps formed between each panel. The presence of these gaps ensures visibility from inside to outside, providing the user with a sense of openness. Meanwhile, the panels have a predetermined thickness, making it possible to block visibility in the direction inclined relative to the lattice fence.

[0006] However, it is difficult to block the view in the direction perpendicular to the lattice fence because the view passes through the gaps between the panels. This can result in privacy not being ensured and security being compromised. If a separate panel were to be installed to cover the gap, this would block the view from the outside through the gap, but it would also block the view from inside to the outside, which could reduce the sense of openness for users.

[0007] In addition, commercially available lattice fences are surrounded by a frame on the periphery, which means that if the size of the lattice fence becomes large, the manufacturing costs increase and it becomes difficult to use.

[0008] The present invention has been made in consideration of such problems, and the object of the present invention is to provide a lattice fence that can ensure the user's visibility to the outside while blocking the view from the front outside when necessary. [Means for solving the problem]

[0009] The lattice 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 for moving the movable lattice fence along the width direction, and can be in an open state in which gaps in the fixed lattice fence are not covered by the movable lattice fence, and a covered state in which the 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 covered state. The movable lattice fence is arranged at a distance along the width direction and has a front The present invention has a plurality of movable panels which move between the open state and the blocked state, and the panel moving mechanism is configured to move the movable panels while maintaining the spacing between the movable panels, and the movable lattice fence further has a movable panel connecting portion extending laterally to connect the movable panels to each other, and the panel moving mechanism has a slit formed in the movable lattice fence and a movable lattice fence mounting portion formed in the fixed lattice fence and inserted into the slit, and the movable lattice fence mounting portion is slidable inside the slit. Effect of the Invention

[0010] The lattice fence of the present invention can provide a lattice fence that can ensure the user's visibility to the outside while blocking views from the front outside as necessary. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the present invention will be described in detail below with reference to the drawings. In the following explanation, the structure of the lattice fence 10 will be explained using each direction, such as outside, inside, left and right, and up and down. Here, the outside refers to the direction facing outward from the site 12 with reference to FIG. 1. The inside refers to the side opposite the outside. The left and right refer to the left and right when the lattice fence 10 is viewed from the inside. In the following explanation, the same components are generally given the same reference symbols, and repeated explanations will be omitted.

[0013] FIG. 1 is a plan view showing a site equipped with a lattice fence 10. Here, a site 12 on which a house 13 is built is shown. The house 13 is built inside the site 12, and a lattice fence 10 is installed on 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 setting the lattice fence 10 in a shielding state, it is possible to block the line of sight from the outside toward the house 13, thereby ensuring the privacy of the user residing in the house 13 and improving the crime prevention in the site 12 and the house 13. In addition, as described later, by setting the lattice fence 10 in an open state by the user's operation, the outside scenery can be viewed through the lattice fence 10, and a certain sense of openness can be obtained. As the material for the lattice fence 10, wood, synthetic resin, metal such as iron, or a composite material thereof can be used.

[0014] The configuration of the lattice fence 10 according to the first embodiment will be described with reference to Figs. 2A to 3C.

[0015] Figure 2A is a perspective view showing the lattice fence 10 according to the first embodiment in an open state, Figure 2B is a front view showing the lattice fence 10 according to the first embodiment in an open state, and Figure 2C is a top view showing the lattice fence 10 according to the first embodiment in an open state.

[0016] As described above, the lattice fence 10 can be in an open state and a closed state. The open state is a state in which the gaps 25 between the fixed panels 21 are not covered by the movable lattice fence 30. The closed state is a state in which 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.

[0017] 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 it blocks visibility from the outside, and when in an open state it ensures good visibility from inside. One example of the lattice fence 10 is a thousand-bar lattice fence. By attaching the fixed lattice fence 20 and the movable lattice fence 30 to the thousand-bar lattice fence 10, the privacy and safety of the thousand-bar lattice lattice fence 10 can be improved.

[0018] The fixed lattice fence 20 has a plurality of fixed panels 21 arranged at intervals along the width direction. The fixed lattice fence 20 has a plurality of fixed panels 21 arranged along the left-right direction that do not move in the open state and the shielded state. The fixed panels 21 are plates having a longitudinal direction along the up-down direction. The fixed panels 21 are spaced apart at approximately equal intervals, and gaps 25 are formed between the fixed panels 21. The fixed panels 21 are connected by the fixed panel connecting parts 26. The fixed panel connecting parts 26 are elongated members extending along the left-right direction. Two fixed panel connecting parts 26 are arranged near the upper end and the lower end of the fixed panel 21. The fixed panel connecting parts 26 are fixed to the inner side surface of the fixed panel 21. The fixed panel connecting parts 26 and the fixed panel 21 can be connected to each other using a connection structure using nails, bolts, adhesives, etc. The same connection structure is also applicable to the connection points of other members. A number of fixed panels 21 are connected by fixed panel connecting parts 26 to form a fixed lattice fence 20 that is generally plate-shaped overall. Posts 23 are provided at both ends of the fixed lattice fence 20 in the left-right direction. Like the fixed panels 21, the middle parts of the posts 23 are supported by the fixed panel connecting parts 26. The posts 23 also extend downward further than the fixed panels 21. Therefore, the lattice fence 10 including the fixed lattice fence 20 can be fixed to the installation surface 11 by burying the areas near the lower ends of the posts 23 provided at both ends of the fixed lattice fence 20 into the installation surface 11 of the site 12 shown in Figure 1.

[0019] The movable lattice fence 30 has movable panels 31 arranged at a distance along the width direction. The movable lattice fence 30 has multiple movable panels 31 that move between the open state and the blocked state. The movable lattice fence 30 is a fence configured so that it can be displaced in the left-right direction relative to the fixed lattice fence 20. The movable lattice fence 30 is a blocking member that blocks the gap 25 as necessary. The movable lattice fence 30 mainly has a movable panel 31 and a movable panel connecting portion 32.

[0020] The movable panels 31 are plates arranged in the left-right direction at a predetermined interval and have their length along the up-down direction. The material of the movable lattice fence 30 can be a non-transparent material that does not allow visible light to pass through, or a semi-transparent material that partially transmits visible light. By using a semi-transparent material for the movable lattice fence 30, it is possible to let in light from outside even when the lattice fence 10 is in a shielded state.

[0021] The movable panel connecting portion 32 extends along the horizontal direction so as to connect the movable panels 31 to each other. The movable panel connecting portion 32 is a member that connects to the vicinity of the upper end of each movable panel 31. The movable panel connecting portion 32 is a plate-shaped member having a longitudinal direction along the left-right direction. Here, the movable panel connecting portion 32 is installed on the outer surface of the movable panel 31. That is, the movable panel connecting portion 32 is disposed between the fixed panel 21 and the movable panel 31. In addition, the right end of the movable panel connecting portion 32 forms a movable panel gripping portion 35 by protruding toward the right. The movable panel gripping portion 35 is a portion that the user grips in order to transition the state of the lattice fence 10 between the shielding state and the open state. As will be described later, when the user holds the movable panel gripping portion 35 and moves the fixed lattice fence 20 to the right, the lattice fence 10 transitions from the open state to the shielding 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.

[0022] The panel movement mechanism 40 is a mechanism configured to be able to move the movable panels 31 while maintaining the distance 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.

[0023] Here, the panel moving mechanism 40 has a slit 41 and a movable lattice fence mounting portion 22.

[0024] The slit 41 is a cutout having a longitudinal direction along the left-right direction that is formed in the movable lattice fence 30. The slit 41 is formed from the rear surface of the movable panel connecting portion 32.

[0025] The movable lattice fence attachment section 22 is a section formed on the fixed lattice fence 20, protrudes inward, and is inserted into the slit 41. Inside the slit 41, the movable lattice fence attachment section 22 is slidable in the left-right direction. This allows the movable panel 31 to slide relative to the fixed panel 21.

[0026] The lattice fence 10 shown in Figure 2A etc. is in an open state, and the gaps 25 of the fixed lattice fence 20 are not blocked by the movable panels 31 of the movable lattice fence 30. In other words, when the lattice fence 10 is viewed from the inside, the fixed panels 21 of the fixed lattice fence 20 and the movable panels 31 of the movable lattice fence 30 overlap. This ensures visibility from the inside to the outside through the gaps 25, allowing the user to view the scenery outside.

[0027] Figure 3A is a perspective view showing the lattice fence 10 according to the first embodiment in a shielding state, Figure 3B is a front view showing the lattice fence 10 according to the first embodiment in a shielding state, and Figure 3C is a top view showing the lattice fence 10 according to the first embodiment in a shielding state.

[0028] To move the lattice fence 10 from the open state shown in Fig. 2A etc. to the closed state shown in Fig. 3A etc., the user slides the movable panel gripping portion 35 to the right. This allows the gap 25 between the fixed panels 21 to 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 fixed panel 21 can appropriately block the line of sight through the gap 25 of the movable panel 31, thereby protecting privacy and improving security.

[0029] To transition from the blocked state to the open state, the user grasps the movable panel gripping portion 35 and moves the movable lattice fence 30 to the left, thereby achieving the open state shown in Fig. 2B, and once again ensuring visibility through the gap 25.

[0030] 2A, the lattice fence 10 according to this embodiment does not have an outer frame that surrounds the entire structure. This allows the lattice fence 10 to be manufactured at low cost and to have greater design freedom. The lattice fence 10 is also easy to use for users.

[0031] The configuration of the lattice fence 10 according to the second embodiment will be described with reference to Figures 4A to 6B. In the lattice fence 10 according to the second embodiment, the movable panel 31 is of a rotatable type that rotates 90 degrees, and other details are the same as in the first embodiment. Here, the movable panel connection part 32 described above is an axial connection part 44. The same applies to the third and subsequent embodiments.

[0032] Figure 4A is a front view showing the lattice fence 10 according to the second embodiment in an open state, Figure 4B is a perspective view showing the lattice fence 10 according to the second embodiment in an open state, and Figure 4C is a top view showing the lattice fence 10 according to the second embodiment in an open state.

[0033] 4C, the movable panel 31 is rotatable, and has a first end 33 which is one end in the width direction, and a second end 34 which is the other end in the width direction. In the open state, the maximum 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 recessed portion 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.

[0034] Referring to Fig. 4B, the panel movement mechanism 40 has a shaft connecting part 44 and a rotating shaft part 43. The shaft connecting part 44 is a substantially rod-shaped member, and is disposed below the fixed panel 21. The shaft connecting part 44 extends in a substantially straight line from the left end to the right end of the lattice fence 10. As shown in Fig. 4B, the rotating shaft part 43 extends upward from the shaft connecting part 44. The rotating shaft part 43 is rotatably connected to the second end part 34 shown in Fig. 4C.

[0035] The movable panel gripping portion 35 is a generally rod-shaped member that extends upward from the right end side, which is the widthwise end of the shaft connecting portion 44. With this configuration, the user can transition the lattice fence 10 between the open state and the closed state by simply moving the movable panel gripping portion 35 left and right. In addition, the user can operate the movable panel gripping portion 35 without crouching.

[0036] A first end 33 of the movable panel 31 is rotatably supported relative to the fixed panel 21 of the fixed lattice fence 20. Referring to FIG. 4B, the first end 33 is formed at the upper and lower ends of the movable panel 31.

[0037] As described above, the second end 34 of the movable panel 31 is connected to the shaft connecting portion 44 via the rotating shaft portion 43. In addition, the second end 34 of the movable panel 31 is connected to the movable panel gripping portion 35 so as to be rotatable.

[0038] Here, the shaft connecting portion 44 and the rotating shaft portion 43 can also be disposed above the fixed panel 21. In such a case, the rotating shaft portion 43 connects 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 above the fixed panel 21. The movable panel gripping portion 35 extends downward from the right end portion of the shaft connecting portion 44.

[0039] Figure 5A is a perspective view showing an intermediate state of the lattice fence 10 according to the second embodiment. Figure 5B is a top view showing the intermediate state of the lattice fence 10 according to the second embodiment.

[0040] With reference to FIG. 5A and FIG. 5B, when the user grips the movable panel gripping portion 35 and pulls it to the right, an intermediate state that is an intermediate state between the open state and the shielded state is realized. Specifically, when the user grips the movable panel gripping portion 35 and moves it to the right side, with reference to FIG. 5B, the second end 34 of the movable panel 31 is pulled to the right via the shaft connecting portion 44 and the rotating shaft portion 43. Then, the movable panel 31 rotates counterclockwise around the first end 33 as the center of rotation. When the user moves the movable panel gripping portion 35 further to the right from the state shown in FIG. 5B, the shielded state described later is reached. At this time, with reference to FIG. 5A, since the shaft connecting portion 44 is disposed below the lower end of the fixed panel 21, the shaft connecting portion 44 can move to the lower side of the fixed panel 21. Therefore, the movement of the shaft connecting portion 44 is not hindered by the fixed panel 21.

[0041] 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.

[0042] 6B, in the blocking 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. As shown in FIG.

[0043] 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 rotating shaft portion 43. This causes the movable panel 31 to rotate further counterclockwise around the first end portion 33 as the center of rotation. 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.

[0044] Here, the movable panel 31 can be easily switched between the open state and the closed state by rotating it by operating 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.

[0045] 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 of a rotatable type in which the movable panel 31 rotates 180 degrees, but other details are the same as those of the first embodiment.

[0046] 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.

[0047] 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.

[0048] The movable panel 31 has a first end 33 and a second end 34. The first end 33 is a right end of the movable panel 31. The first end 33 of the movable panel 31 is rotatably connected to a right end of the fixed panel 21. The second end 34 is a left end of the movable panel 31, and is rotatably connected to a shaft coupling portion 44 via a rotating shaft portion 43.

[0049] The configurations of the rotating 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.

[0050] Figure 8A is a perspective view showing an intermediate state of the lattice fence 10 according to the third embodiment. Figure 8B is a top view showing the intermediate state of the lattice fence 10 according to the third embodiment.

[0051] When the user pulls the movable panel gripping portion 35 to the right, the second end portion 34 of the movable panel 31 is also pulled to the right via the shaft connecting portion 44 and the rotating shaft portion 43. This causes the movable panel 31 to rotate counterclockwise around the first end portion 33 as the center of rotation. Here, the movable panel 31 is shown in a state where it has rotated approximately 90 degrees.

[0052] Fig. 9A is a perspective view showing the shielding state of the lattice fence 10 according to the third embodiment. Fig. 9B is a top view showing the shielding state of the lattice fence 10 according to the third embodiment.

[0053] 9A and 9B, when the user pulls the movable panel gripping portion 35 further to the right, the movable panel 31 rotates further to close the gap 25. Here, the movable panel 31 shows a shielding state in which it has rotated 180 degrees around the first end portion 33 as the center of rotation. In the shielding state, the movable panel 31 is approximately parallel to the direction in which the shaft connecting portion 44 extends. Furthermore, the movable panel 31 moves away from the inner side surface of the fixed panel 21, closing the gap 25.

[0054] 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 closed state shown in Fig. 9B, the movable panel 31 closes the gap 25 between the fixed panels 21. Also, the movable panel gripping portion 35 is a shaft connecting portion 44 connected to the second end portion 34 of the movable panel 31. Furthermore, the shaft connecting portion 44 is disposed below the fixed panel 21. Therefore, by disposing the shaft connecting portion 44 below the fixed panel 21, the displacement of the shaft connecting portion 44 is not hindered by the fixed panel 21.

[0055] The configuration of the 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 a panel movement mechanism 40. Furthermore, in the lattice fence 10 according to the fourth embodiment, the storage form of the movable panel 31 differs from that of the previously described embodiments. Other matters are the same as those of the first embodiment, etc.

[0056] Fig. 10A is a front view showing the lattice fence 10 according to the fourth embodiment in an open state. Fig. 10B is a top view showing the lattice fence 10 according to the fourth embodiment in an open state. Fig. 10C is a perspective view showing the movement restricting part 50 according to the fourth embodiment in an open state. Here, the panel movement mechanism 40 has a panel biasing part 42 and a movement restricting part 50.

[0057] Generally speaking, in the lattice fence 10 here, a panel storage section 45 is 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 advancement and retreat of the movable panel 31.

[0058] 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 capable of storing the movable panel 31 therein.

[0059] The movable panel 31 is stored in the panel storage section 45 in each fixed panel 21 so that it can advance and retreat in the width direction. As described below, 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.

[0060] 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. An elastic body, for example a coil spring, can be used as the panel biasing portion 42. The panel biasing portion 42 is disposed at the left end portion of the panel storage portion 45 and biases the movable panel 31 rightward.

[0061] 10C , the movement restricting portion 50 is configured to restrict the movement of the movable panel 31 from the panel storage portion 45. As described below, the movement restricting portion 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 closed state.

[0062] The regulating connection part 51 is a long member extending along the width direction. A substantially rod-shaped member can be used as the regulating connection part 51. The regulating connection part 51 extends linearly from near the left end part of the lattice fence 10 to near the right end part. The regulating connection part 51 is supported by the fixed panel 21 so as to be rotatable.

[0063] The panel movement restricting portion 52 is connected to the restrictive connection portion 51 and is configured to restrict movement of the movable panel 31 outward in the width direction by coming into contact with the movable panel 31. As shown in Fig. 10C, the panel movement restricting portion 52 is a substantially disk-shaped portion fixed to the restrictive connection portion 51. Also, as shown in Fig. 10B, the panel movement restricting portion 52 is provided corresponding to each movable panel 31. As will be described later, the panel movement restricting portion 52 comes into contact with the right end portion of the movable panel 31 in both the open state and the closed state.

[0064] The restrictive abutment portion 53 is connected to the restrictive connection portion 51 and is configured to abut appropriately against the fixed lattice fence 20. The shape of the restrictive abutment portion 53 is different from that of the panel movement restricting portion 52. The shape of the restrictive abutment portion 53 is, for example, a substantially circular shape with a portion cut out. The restrictive abutment portion 53 abuts against the left end portion of the fixed panel 21 in the open state. Also, the restrictive abutment portion 53 does not abut against the left end portion of the fixed panel 21 in the shielded state. The restrictive abutment portion 53 can be rotated to take an abutment state in which it abuts against the left side surface of the fixed panel 21 and a non-abutment state in which it does not abut against the left side surface of the fixed panel 21.

[0065] In the open state, the restrictive abutment portion 53 abuts against the fixed lattice fence 20, and the position of the panel movement restricting portion 52 is fixed via the restrictive connection portion 51. Specifically, as shown in FIG. 10C, the cutout portion of the restrictive abutment portion 53 is disposed on the outside, and the inner portion of the restrictive abutment portion 53 is substantially circular. Therefore, as shown in FIG. 10B, the restrictive abutment portion 53 of the movement restricting portion 50 abuts against the left side surface of the fixed panel 21 disposed on the leftmost side. As a result, the position of the panel movement restricting portion 52 in the left-right direction is fixed via the restrictive connection portion 51. Specifically, the panel movement restricting portion 52 is disposed immediately adjacent to the right side surface of the fixed panel 21. Therefore, the panel movement restricting portion 52 holds down the right end portion of the restrictive connection portion 51 stored in the panel storage portion 45. As a result, even if the movable panel 31 is urged rightward by the panel urging portion 42, the panel movement restricting portion 52 holds down the movable panel 31. 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.

[0066] 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 later.

[0067] Figure 11A is a front view showing the lattice fence 10 in the shielding state according to the fourth embodiment, Figure 11B is a top view showing the lattice fence 10 in the shielding state according to the fourth embodiment, and Figure 11C is a perspective view showing the movement restricting section 50 in the shielding state according to the fourth embodiment.

[0068] 11C , the user rotates the restricting contact portion 53, so that the cutout portion of the restricting contact portion 53 is positioned on the inside. Here, the rotation of the restricting contact portion 53 may involve only rotating the restricting contact portion 53, or may involve rotating the entire movement restricting portion 50.

[0069] Referring to FIG. 11B, the notch of the restrictive abutment portion 53 is disposed on the inside, so that the restrictive abutment portion 53 does not abut against the left side surface of the fixed panel 21. That is, 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. As a result, each movable panel 31 and the panel movement restricting portion 52 moves toward the right. As a result, the panel movement restricting portion 52 abuts against the right side surface of the fixed panel 21. As a result, the movable panel 31 moves toward the right from the fixed panel 21 and shields the panel movement restricting portion 52. This realizes the shielding state of the lattice fence 10.

[0070] To transition from the closed state to the open state, the user pushes back the movement restricting part 50 to the left, rotating the restricting contact part 53 and engaging 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.

[0071] Here, in the open state, the movement of the movable panel 31 is restricted by the movement restricting portion 50, so that the stored state can be maintained. On the other hand, in the closed state, the restriction is released by rotating the movement restricting portion 50, so that 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, so that the gap 25 between the fixed panels 21 can be filled by the movable panel 31.

[0072] 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.

[0073] Fig. 12A is a top view showing the lattice fence 10 according to the fifth embodiment in an open state, and Fig. 12B is a top view showing the movement restricting section 50 according to the fifth embodiment in a closed state.

[0074] 12A, the movable panel 31 has a first movable panel 311 and a second movable panel 312. The first movable panel 311 and the second movable panel 312 are both stored in the fixed panel 21. The first movable panel 311 and the second movable panel 312 are arranged overlapping each other inside the fixed panel 21. The first movable panel 311 and the second movable panel 312 are connected to each other 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 to the right inside the fixed panel 21. In the open state shown in FIG. 12A, the restricting abutment portion 53 abuts against the left side surface of the fixed panel 21, so that the panel movement restricting portion 52 holds down the first movable panel 311 and the second movable panel 312 in each fixed panel 21.

[0075] 12B, when the engagement between the left side surface of the fixed panel 21 and the restrictive abutment portion 53 is released by the rotation of the restrictive abutment portion 53, the movement restricting portion 50 including the panel movement restricting portion 52 moves to the right due to the biasing force of the panel biasing portion 42. Then, the first movable panel 311 and the second movable panel 312 protrude to the right from the inside of the fixed panel 21 and close the gap 25. This brings about a blocking state in which the gap 25 is closed by the first movable panel 311 and the second movable panel 312.

[0076] To transition from the closed state to the open state, the user pushes back the movement restricting part 50 to the left, rotating the restricting abutment part 53 and engaging the restricting abutment part 53 with the left side surface of the fixed panel 21. This returns to the state shown in Fig. 12A, i.e., the first movable panel 311 and the second movable panel 312 are stored inside the fixed panel 21, and the lattice fence 10 is in the open state.

[0077] 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.

[0078] Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and modifications can be made without departing from the scope of the present invention. In addition, the above-described embodiments can be combined with each other.

[0079] For example, referring to Figure 1, the lattice fence 10 comprises the fixed lattice fence 20, the movable lattice fence 30, and the panel movement mechanism 40, but the mechanism consisting of the movable lattice fence 30 and the panel movement mechanism 40 can also be configured as a movable fence module. In this case, by attaching a movable fence module to the existing lattice fence 10, it is possible to improve the privacy and safety of the existing lattice fence 10.

[0080] Furthermore, in all the embodiments described above, particularly the second and fifth embodiments, the width of gap 25 in the left-right direction may be shorter or longer than the width of fixed panel 21. By making the width of gap 25 shorter than the width of fixed panel 21, the effect of blocking the view from the outside can be made significant. On the other hand, even if the width of gap 25 is wide, a complete blocking state can be created by filling gap 25 with fixed panel 21.

[0081] Furthermore, advertisements and the like can also be displayed on the movable panel 31 described above. For example, referring to Fig. 9B and the like, advertisements, a predetermined pattern, a logo mark, and the like can be displayed on the surface of the movable panel 31 facing outward. In this way, when the lattice fence 10 is in a shielded state, advertisements and the like can be displayed on the outside of the movable panel 31, improving the external design of the lattice fence 10 and enabling the lattice fence 10 to be used in a store or the like.

[0082] The invention that can be understood from the above-described embodiment will be described below together with its effects.

[0083] The lattice fence according to an embodiment 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 can take an open state in which the gaps in the fixed lattice fence are not covered by the movable lattice fence, and a shielded state in which the 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 and 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, and the panel movement mechanism is configured to move the movable panels while maintaining the distance between the movable panels. According to the lattice fence of the present invention, the movable panels of the movable lattice fence can be moved in the width direction by the panel movement mechanism, so that the gaps between the fixed panels can be blocked by the movable panels. Therefore, the movable panels can appropriately block the line of sight through the gaps in the fixed panels, thereby protecting privacy and improving security.

[0084] In addition, in the lattice fence according to an embodiment of the present invention, the movable lattice fence further has a movable panel connecting part extending laterally so as to connect the movable panels to each other, and the panel movement mechanism has a slit formed in the movable lattice fence and a movable lattice fence mounting part formed in the fixed lattice fence and inserted into the slit, and the movable lattice fence mounting part is slidable inside the slit.With the lattice fence of the present invention, because the movable panels are slidable relative to the fixed panels, a user can, for example, slide the movable panel connecting part laterally to close the gap between the fixed panels with the movable panel.

[0085] In addition, in the lattice fence according to the embodiment of the present invention, the panel moving mechanism is characterized in that a first end in the width direction of the movable panel is rotatably supported relative to the fixed lattice fence, and a second end side in the width direction of the movable panel is rotatably connected to the movable panel connecting part. With the lattice fence of the present invention, the movable panel can be rotated by operating the movable panel connecting part, making it easy to switch between an open state and a blocked state.

[0086] Furthermore, in the lattice fence according to an embodiment of the present invention, in the open state, the movable panel is approximately perpendicular to the direction in which the movable panel connection part extends and is in close contact with the fixed panel, and in the blocked state, the movable panel is approximately parallel to the direction in which the movable panel connection part extends and moves away from the fixed panel to close the gap. According to the lattice fence of the present invention, in the open state, the movable panel is in close contact with the fixed panels and does not close the gap between the fixed panels. On the other hand, in the blocked state, the movable panel can be configured to close the gap between the fixed panels.

[0087] Furthermore, in the lattice fence according to an embodiment of the present invention, in the open state, the movable panel is approximately parallel to the direction in which the movable panel connecting portion extends and is in close contact with the fixed panel, and in the shielded 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. According to the lattice fence of the present invention, in the open state, the movable panel overlaps the fixed panels, so that the movable panel does not close the gap between the fixed panels. On the other hand, in the shielded state, the movable panel can be configured to close the gap between the fixed panels.

[0088] Furthermore, in the lattice fence according to the embodiment of the present invention, the movable panel connection part is an axis connection part connected to the second end part of the movable panel, and the axis connection part is arranged below or above the fixed panel. According to the lattice fence of the present invention, by arranging the axis connection part below or above the fixed panel, displacement of the axis connection part is not hindered by the fixed panel.

[0089] In addition, in the lattice fence according to the embodiment of the present invention, the panel movement mechanism further has a movable panel gripping portion that is configured to enable a transition from the open state to the closed state by a user's operation and is configured to extend upward from the width direction end side of the shaft connecting portion. With the lattice fence of the present invention, the state of the movable lattice fence can be transitioned by a simple user operation.

[0090] Moreover, in the lattice fence according to an embodiment of the present invention, the fixed panel is formed with a panel storage section in which the movable panel is stored, and the movable panel is stored in the panel storage section of the fixed panel so as to be able to advance and retreat along the width direction, and the panel movement mechanism is built into the panel storage section and has a panel biasing section that biases the movable panel outward in the width direction, and a movement restricting section that restricts movement of the movable panel from the panel storage section, and the movement restricting section has a restricting connection section that is an elongated member extending along the width direction, and is connected to the restricting connection section and abuts against the movable panel, thereby restricting movement of the movable panel outward in the width direction. The lattice fence of the present invention has a panel movement restricting portion that is connected to the restricting connection portion and configured to abut against the fixed lattice fence, and a restricting abutting portion that is connected to the restricting connection portion and configured to abut against the fixed lattice fence, and in the open state, the restricting abutting portion abuts against the fixed lattice fence, thereby fixing the position of the panel movement restricting portion via the restricting connection portion, and the panel movement restricting portion holds the movable panel, thereby storing the movable panel in the panel storage portion, and in the shielded state, the restricting abutting portion does not abut against the fixed lattice fence, thereby not fixing the position of the panel movement restricting portion, and the movable panel, which is biased by the panel biasing portion, moves outward in the width direction from the panel storage portion. According to the lattice 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 shielded state, the restriction by the movement restricting portion is released, and the biasing force of the panel biasing portion causes the movable panel to protrude outward in the width direction from the panel storage portion of the fixed panel, and the gap between the fixed panels can be filled by the movable panel.

[0091]

[0023] Furthermore, in the lattice fence according to the embodiment of the present invention, the restrictive abutment portion can be in an abutment state in which it abuts against the fixed lattice fence, and a non-abutment state in which it does not abut against the fixed lattice fence, and is configured to switch between the abutment state and the non-abutment state by rotating the restrictive abutment portion. With the lattice fence of the present invention, the abutment state and non-abutment state between the restrictive abutment portion and the fixed lattice fence can be switched between by the simple operation of rotating the restrictive abutment portion, and thus the lattice fence can be easily switched between an open state and a closed state.
