[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 60-68196 Summary of the Invention [Problem to be solved by the invention]

[0005] In conventional latch structures, the latch is inserted into holes formed in the support bracket and the receiving bracket, and in order to improve the operability of the latch, the holes formed in the support bracket and the receiving bracket are made larger than the outer diameter of the latch to provide sufficient clearance. However, with this configuration, when strong winds blow, the latch can move within the holes in the support bracket and the receiving bracket by the amount of the clearance between the latch and the support bracket and the receiving bracket, causing the gate to move back and forth, and this movement of the gate can cause abnormal noise.

[0006] One way to prevent this noise is to reduce the clearance between the latch and the support and receiving brackets. However, if the clearance is reduced, if the gate is misaligned vertically when the latch is operated left or right, the support and receiving brackets will tilt, making it difficult to pass the latch through. In addition, if the latch is operated forcibly, the paint on the latch, support and receiving brackets will be peeled off, causing rust.

[0007] Therefore, the present invention was made in consideration of the above problems, and aims to provide a gate latch that is easy to operate and does not produce abnormal noises when the gate is closed due to strong winds, etc. [Means for solving the problem]

[0008] The gate latch of the present invention is a gate latch having a latch body that is inserted into a support base attached to a gate and a receiving base attached to the other gate or fence and is attached so as to be movable in the width direction of the gate, and a handle that extends in the radial direction of the latch body, wherein the support base and the receiving base have insertion holes through which the latch body is inserted, and the insertion hole formed in at least the receiving base has a slot for passing the handle through, and the insertion hole is formed as an elongated hole that is long in the vertical direction of the gate or in a direction intersecting the vertical direction. The latch body has a noise prevention means that faces the inner periphery of the insertion hole in the width direction at a position that overlaps at least the support base and the receiving base in the radial direction when the latch body is inserted into the receiving base and the handle is engaged with the receiving base. It is characterized by the following.

[0010] Furthermore, in the gate latch of the present invention, it is preferable that the noise prevention means is a spacer attached in a position opposite the inner circumference of the elongated hole in the width direction when the latch body is inserted into the receiving base and the handle is engaged with the receiving base.

[0011] In the gate latch according to the present invention, the spacer is preferably made of synthetic resin.

[0012] In the gate latch according to the present invention, the spacer is preferably made of hard rubber.

[0013] Furthermore, in the gate latch of the present invention, it is preferable that the noise prevention means has a flat portion having a long length positioned opposite the inner circumference of the long hole in the width direction when the latch body is inserted into the receiving base and the handle is engaged with the receiving base.

[0014] In the gate latch according to the present invention, it is preferable that the latch body is a flat rod-shaped member having a series of flat portions formed along the longitudinal direction.

[0016] The above summary of the invention does not list all of the necessary features of the present invention, and subcombinations of these features may also constitute inventions. [Effects of the Invention]

[0017] In the gate latch of the present invention, the support base and the receiving base have insertion holes formed by elongated holes, and the latch body has a noise prevention means at a position that overlaps at least the support base and the receiving base in the radial direction when the latch body is inserted into the receiving base and the handle is engaged with the receiving base, so that when the gate is closed, the noise prevention means acts on the insertion hole, preventing the gate from making noise due to strong winds, etc. Furthermore, when the latch body is operated, the handle is rotated approximately 90 degrees to release the engagement between the handle and the receiving base, so that the noise prevention means of the latch body faces in the direction that coincides with the length direction of the insertion hole, and therefore sufficient clearance can be secured between the noise prevention means and the insertion hole, allowing for smooth operation of the latch body.

[0019] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0021] As shown in Figure 1, the gate latch 30 of this embodiment is attached to a pair of gates 20 that are installed between posts 11 at a predetermined interval and can be opened and closed freely, with posts 11 fixed to a foundation 1 cast into the ground G.

[0022] The gate 20 has a frame body consisting of a pair of horizontal frames 21, 21 and a pair of vertical frames 22, 22, each made of, for example, an L-shaped cross-section angle bar; a center plate 23 arranged substantially parallel to the ground to connect the vertical frames 22, 22; and brace members 28 arranged on diagonal lines of the frame body and connecting the diagonal lines of the frame body. The brace members 28 are preferably made of rods or the like, and ensure the rigidity of the gate 20. A net 27 is also attached to the front of the frame body. Metal wire mesh or the like is preferably used for the net 27 in consideration of wind resistance and durability, but a flat plate such as a punched metal formed with a plurality of predetermined through holes may also be attached.

[0023] The upper horizontal frame 21 is formed with a hanging brace mounting portion 26 for mounting a hanging brace 12 that is attached to the support column 11 in a swingable manner, and the hanging brace mounting portion 26 is attached to the horizontal frame 21 using various integration means such as welding or fastening.

[0024] The center plate 23 is a flat metal member made of steel or the like, and is connected to a pair of vertical frames 22, 22. The vertical frames 22 and the center plate 23 are preferably connected using conventional fastening means such as bolts and nuts.

[0025] Gate 20 is attached so as to be able to open and close freely via hinges 13 attached along the axial direction of support posts 11, and is supported by suspension braces 12 that span from above support posts 11. Suspension braces 12 are attached to support posts 11 via hinges 13 so as to be able to swing in response to the opening and closing of gate 20, and therefore do not interfere with the opening and closing operations of gate 20.

[0026] In addition, the gate 20 has a drop rod 14 attached thereto so as to be able to move vertically and be inserted into a hole 15 formed in the ground G, and by inserting the drop rod 14 into the hole 15, the gate 20 can be prevented from opening or closing and can be fixed in a closed state.

[0027] Of the pair of vertical frames 22, 22, the vertical frame 22 on the support 11 side is fitted with a hinge 13 that attaches the gate 20 to the support 11 so that it can be opened and closed freely, and the vertical frame 22 on the gate 20 side is fitted with a drop rod 14 that can be moved freely in the vertical direction.

[0028] Next, the configuration of the gate latch 30 according to this embodiment will be described. The gate latch 30 according to this embodiment includes a support base 40 attached to one gate 20, a receiving base 50 attached to the other gate 20, and a latch body 31 that passes through the support base 40 and the receiving base 50 and is attached so as to be movable in the width direction of the gate 20.

[0029] 2, the yoke body 31 is, for example, a long, cylindrical member made of steel, and a stopper 34 is attached to the base end so as to protrude radially. This stopper 34 abuts against the support base 40 when the yoke body 31 is moved in the width direction, thereby preventing the yoke body 31 from falling off the support base 40.

[0030] A handle 32 extending in the radial direction is provided on the tip side of the yoke body 31. A groove-shaped receiving base locking portion 33 extending in the extension direction is formed on the handle 32. It is preferable that the handle 32 is integrally connected to the yoke body 31 by welding or the like, but it may also be molded integrally with the yoke body 31.

[0031] In addition, as described below, when the hook body 31 is inserted into the receiving base 50 and the handle 32 is engaged with the receiving base 50, a spacer 61 is attached to the hook body 31 at a position where it overlaps radially with the support base 40 and the receiving base 50 as a noise prevention means.

[0032] The spacer 61 is a curved flat plate member attached to the bar body 31 so as to face the bar body 31 in the radial direction, and is preferably made of a strong synthetic resin such as polyethylene (PE) or polypropylene (PP). The material of the spacer 61 is not limited to synthetic resin, and it may be made of, for example, hard rubber.

[0033] In addition, the spacer 61 has slopes 62 formed at both axial ends, and is configured so that when the hook body 31 is inserted into the support base 40 and the receiving base 50, it can move smoothly in the width direction via the slopes 62, thereby preventing the hook body 31 from getting caught on the support base 40 or the receiving base 50 and causing the operability of the hook body 31 to deteriorate.

[0034] As shown in FIG. 3, the noise prevention means on the yoke body 31a is not limited to being provided with a spacer 61, but may be formed by pressing the yoke body 31a in the radial direction to form a flattened portion 63.

[0035] As shown in Figure 4, the support base 40 includes a pair of outer support bases 41 and an inner support base 42. The outer support base 41 is a member with an L-shaped cross section that has a side plate 45 and an attachment portion 47 that extends substantially vertically from the side plate 45. An insertion hole 43 is formed in the side plate 45, and an attachment hole 48 is formed in the attachment portion 47 for attaching the outer support base 41 to the gate 20. The insertion hole 43 is formed as an elongated hole that is long in the vertical direction of the gate 20. The width of the insertion hole 43 is formed slightly larger than the diameter of the latch body 31 so that the latch body 31 can be easily inserted.

[0036] The inner support base 42 is a member formed in approximately the same shape as the outer support base 41, and has a side plate 46 and an attachment portion 47. The side plate 46 of the inner support base 42 is formed with an insertion hole 43 similar to that of the outer support base 41. The insertion hole 43 of the inner support base 42 is configured as a slot having a groove 44, and is configured so that the handle 32 can be inserted into the groove 44 when the yoke body 31 moves in the width direction. For this reason, the groove width of the groove 44 is formed larger than the thickness of the handle 32.

[0037] As shown in FIG. 5 , the receiving base 50, like the support base 40 described above, includes a pair of inner receiving bases 51 and an outer receiving base 52. The inner receiving base 51 is an L-shaped cross-section member having a side plate 55 and an attachment portion 57 extending substantially vertically from the side plate 55. An insertion hole 53 is formed in the side plate 55, and an attachment hole 58 for attaching the inner receiving base 51 to the gate 20 is formed in the attachment portion 57. The insertion hole 53 is formed as an elongated hole that is long in the vertical direction of the gate 20, similar to the insertion hole 43 formed in the support base 40 described above. The width of the insertion hole 53 is slightly larger than the diameter of the yoke body 31 so that the yoke body 31 can be easily inserted therethrough. The insertion hole 53 of the inner receiving base 51 is configured as a slot having a groove 54, and the handle 32 can be inserted into the groove 54 when the yoke body 31 moves in the width direction. For this reason, the width of the groove 54 is formed to be larger than the thickness of the handle 32 .

[0038] The outer receiving base 52 is a member formed in approximately the same shape as the inner receiving base 51, and has a side plate 56 and an attachment portion 57. The side plate 56 of the outer receiving base 52 has an insertion hole 53 formed therein similar to that of the inner receiving base 51.

[0039] Next, a method of operating the gate latch 30 according to this embodiment will be described with reference to Figures 6 to 9. As shown in Figure 6, in the gate latch 30 according to this embodiment, a support base 40 consisting of an outer support base 41 and an inner support base 42 is attached to the center plate 23 of one gate 20a at a predetermined interval, and a receiving base 50 consisting of an inner receiving base 51 and an outer receiving base 52 is attached to the center plate 23 of the other gate 20b at a predetermined interval.

[0040] The yoke body 31 is attached to the insertion holes 43, 53 of the support base 40 and the receiving base 50 so as to be movable in the width direction, and when the gate 20 is opened or closed, the yoke body 31 moves toward the support base 40 and is not inserted into the receiving base 50. When the yoke body 31 is moved toward the support base 40, the handle 32 and the inner support base 42 interfere with each other, but by inserting the handle 32 into a groove 44 formed in the inner support base 42, the handle 32 can be moved between the inner support base 42 and the outer support base 41.

[0041] Next, to close the gate 20 and secure the closed state, the latch body 31 is moved widthwise to insert into the insertion hole 53 of the receiving base 50. When operating the gate latch 30 according to this embodiment, the handle 32 of the latch body 31 is operated in a horizontal position so that it can be inserted into the groove 44. At this time, as shown in FIG. 7 , the opposing direction of the spacer 61 is positioned so as to overlap the length of the elongated insertion hole 53, which has a length in the vertical direction, so there is sufficient clearance between the insertion hole 53 and the spacer 61. This clearance allows the latch body 31 of the gate latch 30 according to this embodiment to be easily operated. Furthermore, the horizontal orientation of the handle 32 also makes the latch body 31 easier to operate.

[0042] Furthermore, a groove 54 similar to that of the inner support base 42 is formed in the insertion hole 53 of the inner receiving base 51, so that the handle 32 of the latch body 31 can be inserted into the groove 54.

[0043] Next, as shown in Fig. 8, the yoke body 31 is rotated approximately 90 degrees so that the handle 32 faces vertically downward. At this time, the receiving base locking portion 33 formed on the handle 32 engages with the side plate 55 of the inner receiving base 51 via the groove 54. This engagement between the receiving base locking portion 33 and the side plate 55 fixes the yoke body 31 so that it cannot move in the width direction.

[0044] As shown in Figure 9, the handle 32 of the latch body 31 rotates approximately 90 degrees as the receiving base locking portion 33 engages with the side plate 55, so that it faces vertically downward and moves to a position where the facing direction of the spacer 61 overlaps the width direction of the elongated insertion hole 53 having a length in the vertical direction. At this time, the spacer 61 comes into contact with the inner circumferential surface of the insertion hole 53 while elastically deforming. Furthermore, even if the spacer 61 is worn due to long-term use, the clearance between the insertion hole 53 and the spacer 61 becomes very small.

[0045] In this way, with the gate latch 30 of this embodiment, when the latch body 31 is fixed to the receiving base 50, it is possible to reduce rattling between the insertion holes 43, 53 of the support base 40 and the receiving base 50 and the spacer 61 attached to the latch body 31. Therefore, even if a strong wind blows when the gate 20 is closed, it is possible to prevent the latch body 31 from coming into contact with the support base 40 and the receiving base 50, and to prevent abnormal noises from being generated due to the gate 20 moving.

[0046] [Second embodiment] In the gate latch 30 according to the first embodiment described above, a structure including elongated insertion holes 43, 53 formed in the support base 40 and the receiving base 50, and a spacer 61 attached to the latch body 31, as noise prevention means, has been described. The gate latch 30' according to the second embodiment, which will be described next, will be an example of noise prevention means having a different configuration from that of the first embodiment. Note that components that are the same as or similar to those in the first embodiment described above will be assigned the same reference numerals and will not be described again.

[0047] FIG. 10 is a diagram illustrating a gate latch according to a second embodiment of the present invention.

[0048] 10, in the gate latch 30' according to this embodiment, the insertion hole 70 formed in the inner receiving base 51' is formed as a round hole that is slightly larger than the latch body 31. The insertion hole 70 has a V-shaped groove 71 that extends in the vertical direction of the gate 20.

[0049] The yoke body 31 is not provided with a spacer 61, as in the gate yoke 30 according to the first embodiment described above, and is configured as a generally cylindrical member. With the insertion hole 70 having the V-groove 71 and the cylindrical yoke body 31, when the gate 20 is closed, as in the gate yoke 30 according to the first embodiment described above, the receiving base locking portion 33 of the handle 32 engages with the side plate 55 of the inner receiving base 51, and the yoke body 31 fits into the V-groove 71, and the yoke body 31 comes into contact with both sides of the V-groove 71, resulting in two-point contact, which prevents rattle between the yoke body 31 and the receiving base 50 and thereby prevents the generation of abnormal noise.

[0050] Although the configuration of the inner receiving base 51' has been described for the gate latch 30' according to the present embodiment, it is preferable to form insertion holes with V-shaped grooves in the outer receiving base and support base as well, similar to the inner receiving base 51' described above.

[0051] In the above embodiment, the elongated hole shape of the insertion holes 43, 53 in the gate latch 30 according to the first embodiment has been described as being elongated in the vertical direction. However, the elongated hole length is not limited to this. For example, the elongated hole length may be configured to be horizontal. In the above embodiment, the gate 20 is described as a double-swing gate 20 having a pair of gate leaves 20, 20. However, the gate 20 may be configured as a single-swing gate. Furthermore, the support base and receiving base have been described as including a pair of inner and outer support bases, and a pair of inner and outer receiving bases. However, the number of each base may be increased or decreased as appropriate. It is clear from the claims that such modifications and improvements are also within the technical scope of the present invention. [Explanation of symbols]
