Description

fence

[0001] The present invention relates to a fence.

[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.

[0003] Japanese Utility Model Application Publication No. 54-103061 Japanese Utility Model Application Publication No. 51-81539 Japanese Utility Model Application Publication No. 56-15329 Japanese Utility Model Application Publication No. 57-77596 Japanese Utility Model Application Publication No. 60-70195 Japanese Utility Model Application Publication No. 7-32003 Japanese Patent Application Publication No. 2003-155847 Japanese Patent Application Publication No. 3233489

[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 member, and there is a problem in that a gap of this distance is created when the fence is 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.

[0010] A 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 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 covered 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 covered 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 covered state. The panel further comprises a movable panel and a movable panel connecting portion extending laterally to connect the movable panels to each other, 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.

[0014] An embodiment of the present invention will be described in detail below with reference to the drawings. In the following description, the structure of the lattice fence 10 will be described using directions such as outside, inside, left and right, and up and down. Here, with reference to FIG. 1 , outside refers to the direction facing outward from the site 12. Inside refers to the side opposite the outside. Left and right refer to the left and right when viewing the lattice fence 10 from the inside. In the following description, identical components will generally be given the same reference numerals, and repeated explanations will be omitted. In this embodiment, the lattice fence 10 will be used as an example of a fence.

[0015] FIG. 1 is a plan view showing a site equipped with a lattice fence 10. The site 12 shown here has a house 13 built on it. The house 13 is built inside the site 12, and the lattice fence 10 is installed along part of the outer edge of the site 12. The lattice fence 10 is installed on an installation surface 11, which is the edge of the site 12. By placing the lattice fence 10 in a shielded state, it is possible to block views of the house 13 from the outside, thereby ensuring the privacy of users residing in the house 13 and improving crime prevention for the site 12 and the house 13. Furthermore, as described below, by opening the lattice fence 10 through a user's operation, the user can view the outside scenery through the lattice fence 10, providing a certain sense of openness. The lattice fence 10 can be made of wood, synthetic resin, metal such as iron, or a composite material thereof.

[0016] The configuration of the lattice fence 10 according to the first embodiment will be described with reference to Figures 2A to 3C.

[0017] 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.

[0018] 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.

[0019] 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 blocks visibility from the outside when in a shielded state, and ensures good visibility from the inside when in an open state. 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.

[0020] The fixed lattice fence 20 has multiple fixed panels 21 spaced apart along the width direction. The fixed lattice fence 20 has multiple fixed panels 21 arranged along the left-right direction that do not move in the open state or the closed state. The fixed panels 21 are plates with a longitudinal direction along the up-down direction. The fixed panels 21 are spaced at approximately equal intervals, and gaps 25 are formed between the fixed panels 21. The fixed panels 21 are connected by fixed panel connecting portions 26. The fixed panel connecting portions 26 are elongated members extending along the left-right direction. Two fixed panel connecting portions 26 are arranged near the upper and lower ends of the fixed panels 21. The fixed panel connecting portions 26 are fixed to the inner surface of the fixed panel 21. The fixed panel connecting portions 26 and the fixed panels 21 can be connected using a connection structure using nails, bolts, adhesive, etc. This connection structure is also applicable to connection points of other components. A plurality of fixed panels 21 are connected by fixed panel connectors 26 to form a generally plate-shaped fixed lattice fence 20. Support posts 23 are provided at both ends of the fixed lattice fence 20 in the left-right direction. Like the fixed panels 21, the support posts 23 are supported at their midpoints by the fixed panel connectors 26. The support posts 23 also extend downward below the fixed panels 21. Therefore, by burying the lower ends of the support posts 23 provided at both ends of the fixed lattice fence 20 near the installation surface 11 of the site 12 shown in Figure 1 , the lattice fence 10 including the fixed lattice fence 20 can be fixed to the installation surface 11.

[0021] The movable lattice fence 30 has movable panels 31 spaced apart along the width direction. The movable lattice fence 30 has multiple movable panels 31 that move between the open state and the shielded state. The movable lattice fence 30 is a fence configured to be displaceable along the left-right direction relative to the fixed lattice fence 20. The movable lattice fence 30 is a shielding member that closes the gap 25 as needed. The movable lattice fence 30 mainly has movable panels 31 and movable panel connecting parts 32.

[0022] 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 movable lattice fence 30 can be made of 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.

[0023] 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.

[0024] The panel moving 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 moving mechanism 40 is configured to be able to move the movable lattice fence 30 along the width direction.

[0025] Here, the panel moving mechanism 40 has a slit 41 and a movable lattice fence mounting portion 22.

[0026] 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.

[0027] The movable lattice fence mounting section 22 is formed on the fixed lattice fence 20, protrudes inward, and is inserted into the slit 41. Inside the slit 41, the movable lattice fence mounting section 22 is slidable in the left-right direction, allowing the movable panel 31 to slide relative to the fixed panel 21.

[0028] The lattice fence 10 shown in Figure 2A and other figures is in an open state, and the gaps 25 in 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 users to view the scenery outside.

[0029] 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.

[0030] To move the lattice fence 10 from the open state shown in Figure 2A etc. to the closed state shown in Figure 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 Figure 2B, the movable lattice fence mounting portion 22 is positioned at the left end inside the slit 41. Therefore, the fixed panel 21 can appropriately block views through the gap 25 between the movable panels 31, thereby protecting privacy and improving security.

[0031] To transition from the closed state to the open state, the user grasps the movable panel grip 35 and moves the movable lattice fence 30 to the left, thereby achieving the open state shown in Figure 2B, and once again ensuring visibility through the gap 25.

[0032] 2A, the lattice fence 10 according to this embodiment does not have an outer frame surrounding the entire structure. This reduces manufacturing costs and increases design freedom. Furthermore, the lattice fence 10 is easier for users to use.

[0033] 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 a rotatable type that rotates 90 degrees, but other details are the same as in the first embodiment. Here, the movable panel connecting portion 32 described above is a shaft connecting portion 44. The same applies to the third and subsequent embodiments.

[0034] 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.

[0035] 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 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.

[0036] Referring to Figure 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 generally rod-shaped member and is disposed below the fixed panel 21. The shaft connecting portion 44 extends in a generally straight line from the left end to the right end of the lattice fence 10. As shown in Figure 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 Figure 4C.

[0037] The movable panel gripping portion 35 is a generally rod-shaped member that extends upward from the right end, which is the widthwise end of the shaft connecting portion 44. The configuration including the movable panel gripping portion 35 allows the user to 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. The user can also operate the movable panel gripping portion 35 without crouching.

[0038] The 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 Figure 4B, the first end 33 is formed at the upper and lower ends of the movable panel 31.

[0039] As described above, the second end 34 of the movable panel 31 is connected to the shaft connecting portion 44 via the rotation shaft portion 43. In addition, the second end 34 of the movable panel 31 is rotatably connected to the movable panel gripping portion 35.

[0040] 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 to the right end of the fixed lattice fence 20 above the fixed panel 21. The movable panel gripping portion 35 extends downward from the right end of the shaft connecting portion 44.

[0041] 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.

[0042] 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 rotation 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, described below, 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 downward of the fixed panel 21. Therefore, the movement of the pivot coupling portion 44 is not hindered by the fixed panel 21.

[0043] 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.

[0044] Referring to FIG. 6B , in the shielded state, the movable panel 31 is substantially 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 .

[0045] Specifically, when the user pulls the movable panel grip 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 connection portion 44 and the rotation shaft portion 43. This causes the movable panel 31 to further rotate counterclockwise around the first end portion 33. 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.

[0046] 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.

[0047] 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 has a rotating movable panel 31 that rotates 180 degrees, but other features are the same as those of the first embodiment.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] When the user pulls the movable panel grip portion 35 to the right, the second end portion 34 of the movable panel 31 is also pulled to the right via the shaft connection portion 44 and the rotation shaft portion 43. This causes the movable panel 31 to rotate counterclockwise around the first end portion 33. Here, the movable panel 31 is shown in a state where it has rotated approximately 90 degrees.

[0054] Figure 9A is a perspective view showing the shielding state of the lattice fence 10 according to the third embodiment. Figure 9B is a top view showing the shielding state of the lattice fence 10 according to the third embodiment.

[0055] 9A and 9B , when the user pulls the movable panel grip portion 35 further to the right, the movable panel 31 further rotates to close the gap 25. Here, the movable panel 31 is shown in a shielded state rotated 180 degrees around the first end portion 33. In the shielded state, the movable panel 31 is substantially parallel to the direction in which the shaft connection portion 44 extends. Furthermore, the movable panel 31 moves away from the inner side surface of the fixed panel 21, closing the gap 25.

[0056] Here, as shown in Fig. 7C , in the open state, the movable panel 31 overlaps the fixed panel 21, so that the movable panel 31 does not block the gap 25 between the fixed panels 21. On the other hand, in the closed state shown in Fig. 9B , the movable panel 31 blocks the gap 25 between the fixed panels 21. Also, the movable panel gripping portion 35 is a pivotal connecting portion 44 connected to the second end 34 of the movable panel 31. Furthermore, the pivotal connecting portion 44 is disposed below the fixed panel 21. Therefore, by disposing the pivotal connecting portion 44 below the fixed panel 21, the displacement of the pivotal connecting portion 44 is not hindered by the fixed panel 21.

[0057] 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 unit 50 as a 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.

[0058] Figure 10A is a front view showing the lattice fence 10 according to the fourth embodiment in an open state. Figure 10B is a top view showing the lattice fence 10 according to the fourth embodiment in an open state. Figure 10C is a perspective view showing the movement restriction unit 50 according to the fourth embodiment in an open state. Here, the panel movement mechanism 40 has a panel biasing unit 42 and a movement restriction unit 50.

[0059] 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. The movement of the movable panel 31 is controlled by a movement restriction section 50.

[0060] 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.

[0061] 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.

[0062] 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 rightward.

[0063] 10C , the movement restricting portion 50 is configured to restrict movement of the movable panel 31 from the panel storage portion 45. As will be described later, 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. Specifically, the movement restricting portion 50 has a restricting connection portion 51, a panel movement restricting portion 52, and a restricting abutment portion 53.

[0064] The restrictive connection portion 51 is a long member that extends along the width direction. A generally rod-shaped member can be used as the restrictive connection portion 51. The restrictive connection portion 51 extends linearly from near the left end of the lattice fence 10 to near the right end. The restrictive connection portion 51 is rotatably supported by the fixed panel 21.

[0065] The panel movement restricting portion 52 is connected to the restricting connection portion 51 and configured to restrict outward movement of the movable panel 31 in the width direction by contacting the movable panel 31. As shown in Fig. 10C, the panel movement restricting portion 52 is a substantially disk-shaped portion fixed to the restricting connection portion 51. Also, as shown in Fig. 10B, a panel movement restricting portion 52 is provided corresponding to each movable panel 31. As will be described later, the panel movement restricting portion 52 contacts the right end portion of the movable panel 31 in both the open state and the closed state.

[0066] The restrictive abutment portion 53 is connected to the restrictive connection portion 51 and is configured to abut against the fixed lattice fence 20 as appropriate. 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. Furthermore, 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.

[0067] 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 generally 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 leftmost fixed panel 21. 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 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.

[0068] 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.

[0069] 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 restriction unit 50 according to the fourth embodiment.

[0070] 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.

[0071] Referring to Figure 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 outward 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.

[0072] To transition from the closed state to the open state, the user pushes the movement restricting part 50 back 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.

[0073] In the open state, the movement of the movable panel 31 is restricted by the movement restricting portion 50, thereby maintaining the housed 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 housing portion 45 of the fixed panel 21, so that the movable panel 31 can fill the gap 25 between the fixed panels 21.

[0074] The configuration of the lattice fence 10 according to the fifth embodiment will be described with reference to Figures 12A and 12B. The lattice fence 10 according to the fifth embodiment has a movable panel 31 that includes a first movable panel 311 and a second movable panel 312, and is otherwise similar to the fourth embodiment.

[0075] 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.

[0076] 12A , the movable panel 31 includes 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 overlapping each other inside the fixed panel 21. 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 abutment portion 53 abuts against the left side surface of the fixed panel 21, causing the panel movement restricting portion 52 to press the first movable panel 311 and the second movable panel 312 in each fixed panel 21.

[0077] 12B , when restricting contact portion 53 rotates and disengages from the left side surface of fixed panel 21, movement restricting portion 50 including panel movement restricting portion 52 moves toward the right due to the biasing force of panel biasing portion 42. This causes first movable panel 311 and second movable panel 312 to protrude toward the right from inside fixed panel 21 and close gap 25. This creates a shielded state in which gap 25 is closed by first movable panel 311 and second movable panel 312.

[0078] To transition from the closed state to the open state, the user pushes the movement restricting part 50 back 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 Figure 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.

[0079] Here, the movable panel 31 is composed of a first movable panel 311 and a second movable panel 312, so that the width of the fixed panel 21 can be narrowed.

[0080] The configuration of a lattice fence 10 according to the sixth embodiment will be described with reference to Figures 13A to 13C. Figure 13A is a front view showing the lattice fence 10 according to the sixth embodiment in an open state. Figure 13B is a perspective view showing the lattice fence 10 according to the sixth embodiment in an open state. Figure 13C is a top view showing the lattice fence 10 according to the sixth embodiment in an open state.

[0081] The basic configuration and operation of the lattice fence 10 according to the sixth embodiment are the same as those of the lattice fence 10 according to the third embodiment shown in Figure 7A, etc., and therefore the following explanation will focus on the differences, and explanations of the common configurations, etc. will be omitted and used by reference.

[0082] Here, the movable panel gripping portion 35 is provided at the middle portion of the shaft connecting portion 44 in the width direction. As an example, the movable panel gripping portion 35 is disposed at approximately the center 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 that extends upward from approximately the center portion of the shaft connecting portion 44.

[0083] When the user opens or closes the movable panel 31, the user operates it by gripping the movable panel gripping portion 35. The movable panel gripping portion 35 is disposed approximately in the center of the pivot connecting portion 44, so that each movable panel 31 can be smoothly rotated via the movable panel gripping portion 35 and the pivot connecting portion 44.

[0084] 13C , the movable panel gripping portion 35 may be disposed more inward than the fixed panel connecting portion 26. In this case, the movable panel gripping portion 35 extends from approximately the center of the pivot connecting portion 44 in the width direction, through the pivot connecting portion 44 and the lower portion of the fixed panel connecting portion 26, to a position more inward than the fixed panel connecting portion 26, and then further upward. In this manner, the user can rotate the movable panel 31 in both directions by operating the movable panel gripping portion 35 located more inward than the fixed panel connecting portion 26.

[0085] 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.

[0086] 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., and therefore the following explanation will focus on the differences, and the common configurations will be omitted and used by reference.

[0087] 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.

[0088] The configuration of the lattice fence 10 according to the eighth embodiment will be described with reference to Figures 15A to 16C.

[0089] 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.

[0090] The basic configuration and operation of the lattice fence 10 according to the eighth embodiment are the same as those of the lattice fence 10 according to the first embodiment shown in Figure 2A and elsewhere, so differences will be mainly described below, and explanations of common configurations will be omitted. Figures 15B and 15C do not show the movable panel connectors 32 in order to clearly show the rail mechanism 37. In an actual lattice fence 10, the movable panel connectors 32 commonly secure the inner or outer surfaces of the movable panels 31.

[0091] 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 that it can move 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 on the upper portion of the lattice fence 10, only on the lower portion, or on both the upper and lower portions.

[0092] Figure 16A is a front view showing the shielding state of the lattice fence 10 according to the eighth embodiment, Figure 16B is a perspective view showing the shielding state of the lattice fence 10 according to the eighth embodiment, and Figure 16C is a top view showing the shielding state of the lattice fence 10 according to the eighth embodiment.

[0093] 16B and 16C , when the user operates the movable panel gripping portion 35 to the right, the movable lattice fence 30 moves to the right and the movable panel 31 is positioned to block the gap 25. This configuration makes it possible to block views from outside through the gap 25. In the shielded state, the rail mechanism 37 guides and holds the movable panel 31 as it moves to the right. Conversely, when transitioning from the shielded state to the open state, the user pushes the movable panel gripping portion 35 to the left, displacing the movable panel 31, which is guided by the rail mechanism 37, to the left.

[0094] 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 portions and rail receiving portions that make up the rail mechanism 37 within the thickness portions of the fixed panel 21 and the movable panel 31.

[0095] The rail mechanism 37 may be provided with a stopper that controls the amount of left-right movement of the movable panel 31. Such a stopper can prevent the movable panel 31 from moving excessively leftward and in the direction A.

[0096] The configuration 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 is 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.

[0097] 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.

[0098] 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.

[0099] Referring to Figure 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 generally rod-shaped member and is disposed below the fixed panel 21. The shaft connecting portion 44 extends in a generally straight line from the left end to the right end of the lattice fence 10. As shown in Figure 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 Figure 17C.

[0100] The movable panel gripping portion 35 is a generally rod-shaped member that extends upward from the right end, which is the widthwise end of the shaft connecting portion 44. The configuration including the movable panel gripping portion 35 allows the user to 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. The user can also operate the movable panel gripping portion 35 without crouching.

[0101] 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. 17B, the first end 33 is formed at the upper and lower ends of the movable panel 31. As shown in Fig. 17C, the first end 33 is rotatably connected to the inside of the right side surface of the fixed panel 21.

[0102] Figure 18A is a perspective view showing an intermediate state of the lattice fence 10 according to the ninth embodiment. Figure 18B is a top view showing the intermediate state of the lattice fence 10 according to the ninth embodiment.

[0103] 18A and 18B , when the user grasps 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 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. 18B , the second end 34 of the movable panel 31 is pulled to the right via the shaft connecting portion 44 and the rotation shaft portion 43. This causes the movable panel 31 to rotate clockwise around the first end 33 as the rotation center. When the user further moves the movable panel gripping portion 35 to the right from the state shown in FIG. 18B , the closed state, which will be described later, is realized.

[0104] Figure 19A is a perspective view showing the shielding state of the lattice fence 10 according to the ninth embodiment. Figure 19B is a top view showing the shielding state of the lattice fence 10 according to the ninth embodiment.

[0105] Referring to FIG. 19B, in the shielded 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 .

[0106] Specifically, when the user pulls the movable panel grip 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 connection portion 44 and the rotation shaft portion 43. This causes the movable panel 31 to rotate further clockwise 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.

[0107] Although the embodiments of the present invention have been described above, the present invention is not limited to these and can be modified within the scope of the present invention. In addition, the above-described embodiments can be combined with each other.

[0108] For example, referring to Figure 1, the lattice fence 10 includes 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, the privacy and safety of the existing lattice fence 10 can be improved.

[0109] Furthermore, in all of the above-described embodiments, particularly the second and fifth embodiments, the width of the gap 25 in the left-right direction 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 more pronounced. On the other hand, even if the width of the gap 25 is wide, by filling the gap 25 with the fixed panel 21, a complete shielding state can be created.

[0110] Furthermore, advertisements and the like can also be displayed on the aforementioned movable panel 31. For example, referring to Figure 9B and other figures, advertisements, predetermined patterns, logos, and the like can be displayed on the outward-facing surfaces of the fixed panel 21 and the movable panel 31. 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 appearance and design of the lattice fence 10 and allowing the lattice fence 10 to be used in stores and the like.

[0111] Furthermore, the lattice fence 10 of the fourth embodiment shown in Figures 10A to 11C can also be equipped with the configuration of the slits 41 and movable lattice fence mounting portion 22 shown in the second embodiment shown in Figures 2A to 3C, as well as the rail mechanism 37 shown in Figure 16B, etc.

[0112] Furthermore, in each of the above-described embodiments, the lattice fence 10 can also be used for purposes other than installation on the property 12. For example, the lattice fence 10 can be installed on the windows of a house 13. In other words, the lattice fence 10 can also be used as a window grille.

[0113] Furthermore, in all the embodiments, the positions of the fixed panel 21 and the movable panel 31 can be interchanged. For example, referring to Fig. 2C, the fixed panel 21 can be disposed on the inside, and the movable panel 31 can be disposed on the outside.

[0114] The invention that can be understood from the above-described embodiment will be described below together with its effects.

[0115]

[0006] A 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 for moving the movable lattice fence along a width direction. The lattice fence 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 multiple fixed panels spaced apart along the width direction that do not move between the open state and the covered state. The movable lattice fence has multiple movable panels spaced apart along the width direction that move between the open state and the covered state. The panel movement mechanism is configured to move the movable panels while maintaining the spacing between the movable panels. With this lattice fence, the movable panels of the movable lattice fence can be moved widthwise by the panel movement mechanism, thereby blocking the gaps between the fixed panels. This allows the movable panels to appropriately block views through the gaps in the fixed panels, thereby protecting privacy and improving security.

[0116] In addition, in the lattice fence according to an embodiment of the present invention, the movable lattice fence further has movable panel connecting parts extending laterally to connect the movable panels together, and the panel movement mechanism has slits formed in the movable lattice fence and movable lattice fence mounting parts formed in the fixed lattice fence and inserted into the slits, and the movable lattice fence mounting parts are slidable within the slits.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 parts laterally to close the gaps between the fixed panels with the movable panels.

[0117] In addition, in the lattice fence according to an embodiment of the present invention, the panel movement 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 in the width direction of the movable panel is rotatably connected to the movable panel connector. With the lattice fence of the present invention, the movable panel can be rotated by operating the movable panel connector, making it easy to switch between an open state and a closed state.

[0118] 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 connector 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 connector 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, so that the movable panel does not close the gap between the fixed panels. On the other hand, in the closed state, the movable panel can be configured to close the gap between the fixed panels.

[0119] 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 extension direction of the movable panel connector and is in close contact with the fixed panel, and in the shielded state, the movable panel is approximately parallel to the extension direction of the movable panel connector 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 panel, 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.

[0120] In addition, in the lattice fence according to an embodiment of the present invention, the movable panel connecting portion is an axle connecting portion that is connected to the second end portion of the movable panel, and the axle connecting portion is located below or above the fixed panel. According to the lattice fence of the present invention, by locating the axle connecting portion below or above the fixed panel, displacement of the axle connecting portion is not hindered by the fixed panel.

[0121] In addition, in the lattice fence according to an embodiment of the present invention, the panel movement mechanism further includes 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 that is configured to extend upward from the widthwise 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.

[0122] Furthermore, 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 connecting section that is an elongated member that extends along the width direction, and is connected to the restricting connecting section and comes into contact with the movable panel, thereby restricting movement of the movable panel outward in the width direction. and a restrictive abutment portion connected to the restrictive connection portion and configured to abut against the fixed lattice fence, wherein in the open state, the restrictive abutment portion abuts against the fixed lattice fence, fixing the position of the panel movement restricting portion via the restrictive connection portion, and the panel movement restricting portion presses the movable panel, storing the movable panel in the panel storage portion; and in the closed state, the restrictive abutment portion does not abut against the fixed lattice fence, fixing the position of the panel movement restricting portion, and the movable panel, 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 movable panel stored in the panel storage portion of the fixed panel. On the other hand, in the closed state, the restriction by the movement restricting portion is released, causing the biasing force of the panel biasing portion to cause the movable panel to protrude outward in the width direction from the panel storage portion of the fixed panel, allowing the movable panel to fill the gap between the fixed panels.

[0123] In addition, in the lattice fence according to an embodiment of the present invention, the restrictive abutment portion can be placed in an abutment state in which it abuts against the fixed lattice fence, and in 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 between the restrictive abutment portion and the fixed lattice fence can be switched between the abutment state and the non-abutment state by the simple operation of rotating the restrictive abutment portion, and therefore the lattice fence can be easily switched between an open state and a closed state.
