[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A handle device according to an embodiment of the present invention will now be described with reference to the drawings.

[0010] Fig. 1 is a perspective view showing a schematic configuration of a door 100 equipped with a handle device 1 and a latch lock 1000 according to an embodiment of the present invention. Fig. 2 is a perspective view showing a schematic configuration of the handle device 1. Fig. 3 is a front view of the handle device 1 and the latch lock 1000. Fig. 4 is a rear view of the handle device 1 and the latch lock 1000. Fig. 5 is a cross-sectional view of the handle device 1 and the latch lock 1000 taken along line AA.

[0011] In the following description, for convenience, the short side direction (x-axis direction) of the interior surface 102 of the door 100 shown in Figure 1 will be referred to as the width direction or left-right direction. The width direction of the door 100 is also the protruding direction of the latch bolt 1110 of the latch lock 1000. In addition, in the following description, the thickness direction of the door 100, i.e., the direction parallel to the short side direction of the side surface 103 (y-axis direction), will be referred to as the front-rear direction or the interior-exterior direction. In addition, in the following description, the longitudinal direction (z-axis direction) of the door 100 will be referred to as the up-down direction, vertical direction, or height direction.

[0012] As shown in Fig. 1, a handle device 1 according to this embodiment is attached to an indoor surface 102 of a door 100 having an exterior surface 101 that is the exterior surface and an interior surface 102 that is the interior surface, and constitutes a part of an opening and closing device for the door 100. As shown in Figs. 5 and 6, the handle device 1 includes an indoor base 27 attached to the indoor surface 102, a pin 28 fixed to the indoor base 27 with the vertical direction as the longitudinal direction, a handle arm 25 having a tip end 251 to which a handle bar 40 is attached and a base end 252 rotatably supported on the indoor base 27 via the pin 28, and an operating piece 31 fixed to the base end 252 of the handle arm 25 and protruding into a latch lock housing 1002 of a latch lock 1000 built into the door 100 to contact an operated piece 1009 of the latch lock 1000. The base end 252 of the handle arm 25 has a flat base portion 253 facing the indoor wall 102, at least one protrusion 254 extending from the base portion 253 toward the indoor wall 102, and a screw hole 255 provided away from the protrusion 254. The operation piece 31 has an operation piece main body 311 that contacts the operated piece 1009, a flat portion 313 that can be joined to the base portion 253, a notch portion 314 that can receive the protrusion 254, and a through hole 315 that is provided in the center of the flat portion 313 and away from the notch portion 314. The operation piece 31 is fixed to the base end 252 of the handle arm 25 with a screw 256 that is inserted through the through hole 315 and screwed into the screw hole 255. The configuration and operation of the handle device 1 will be described in detail below.

[0013] [Structure of the handle device] The door 100 shown in FIG. 1 is, for example, a front door. The door 100 is equipped with a so-called push-pull type handle device 1. The door 100 is attached to a door frame (not shown) so as to be able to open and close. The end of the door 100 (on the left side in the drawing, on the side where the handle device 1 is not attached) is connected to the door frame by a hinge (not shown). The door 100 can rotate around the hinge. In other words, the door 100 shown in FIG. 1 is a so-called left-handed door. In addition to the handle device 1, the door 100 is also equipped with, for example, a battery box 500, an upper box lock 600, and a lower box lock 700.

[0014] As shown in FIGS. 1 to 4, the handle device 1 includes an upper handle device 10U, a lower handle device 10L, and a handle bar 40. The upper handle device 10U and the lower handle device 10L each include a handle arm cover 20 and a base cover 30. The handle arm cover 20 is a member that covers the handle arms 25 of the upper handle device 10U and the lower handle device 10L from the outside, i.e., the interior side in the y-axis direction. The base cover 30 is a member that covers the interior base 27 of the upper handle device 10U and the lower handle device 10L from the outside, i.e., the interior side in the y-axis direction. As shown in FIG. 1, both the upper handle device 10U and the lower handle device 10L are attached to the interior surface 102 of the door 100. The upper handle device 10U supports the upper and lower upper sides of the handle bar 40. The lower handle device 10L supports the lower side of the handle bar 40 in the vertical direction.

[0015] The upper handle device 10U and the lower handle device 10L each include a handle arm 25, an indoor base 27, a pin 28, an operating piece 31, and a torsion spring 33. The main differences between the upper handle device 10U and the lower handle device 10L are that the attachment positions to the door 100 are different due to the difference in the support position of the handle bar 40 described above, and that the latch lock 1000 is provided on the tip side of the operating piece 31 in the upper handle device 10U, i.e., on the outdoor side in the indoor / outdoor direction (y-axis direction) of the door 100. For this reason, the following explanation will mainly focus on the upper handle device 10U.

[0016] The handle arm 25 has a tip end portion 251 , a base end portion 252 , a base portion 253 , a protrusion 254 , and a screw hole 255 .

[0017] 5, the handle arm 25 extends from a base end 252 attached to the interior base 27 toward a tip end 251 provided on the left side in the left-right direction (x-axis direction) of the door 100. As described above, the handle bar 40 is attached to the tip end 251.

[0018] The base end 252 is supported by the indoor base 27 via a pin 28 so as to be rotatable in the direction of arrow A (horizontally) relative to the indoor base 27. An operating piece 31 is provided on the base end 252. The operating piece 31 protrudes into a latch lock housing 1002 of a latch lock 1000 built into the door 100. The operating piece 31 swings horizontally when the handle bar 40 is operated, and comes into contact with an operated piece 1009 of the latch lock 1000, which is a member separate from the handle device.

[0019] Fig. 6 is a rear view of the upper handle device 10U constituting the handle device 1. Fig. 7 is an enlarged rear view showing a fixing portion between the operating piece 31 and the handle arm 25 of the upper handle device 10U.

[0020] As shown in Figures 6 and 7, the base end 252 of the handle arm 25 is provided with a base portion 253, a protrusion 254, and a screw hole 255. The base portion 253 is formed in a flat surface facing the interior surface 102 of the door 100. The base portion 253 is formed in a flat surface. The screw hole 255 is provided in the center of the flat surface portion 313. At least one protrusion 254 is provided on the flat surface portion 313 around the screw hole 255. In this embodiment, a plurality of protrusions 254, for example, three protrusions 254, are provided. The protrusions 254 extend in a convex shape toward the interior surface 102.

[0021] The operation piece 31 has an operation piece main body 311, a flat surface 313, a notch 314, and a through hole 315. The operation piece 31 is fixed to the base end 252 of the handle arm 25 with a screw 256 that is inserted through the through hole 315 and threaded into a screw hole 255. The operation piece main body 311 extends from the flat surface 313 and comes into contact with the operated piece 1009 when the handle arm 25 is operated and the handle arm 25 and the operation piece 31 swing as indicated by arrow A. The operation piece main body 311 is formed in a shape that can come into contact with the operated piece 1009, for example, a plate shape. The flat surface 313 is joined to the base 253 and therefore has a shape that corresponds to the base 253, for example, a flat surface. The cutout portions 314 are cut out to match the number and shape of at least one protrusion 254 so that the protrusions 254 can be received therein and prevent interference between the protrusions 254 and the flat portion 313 when joining the base portion 253 and the flat portion 313 of the handle arm 25. The through-holes 315 are holes for inserting screws 256 used to join and fasten the operation lever 31 and the handle arm 25. For this reason, the through-holes 315 are provided in the center of the flat portion 313. The through-holes 315, together with the multiple protrusions 254 and the cutout portions 314, function to determine the joining position between the base portion 253 and the flat portion 313. Because the operation lever 31 and the handle arm 25 are screwed together with the cutout portions 314 and the protrusions 254 engaged with each other, even if the screw loosens, the flat portion 313 is prevented from rotating around the screw 256. This prevents the operation piece main body 311 from rotating, allowing it to come into firm contact with the operated piece 1009 of the latch lock.

[0022] Fig. 8 is a perspective view of an upper handle device 10U constituting the handle device 1. Fig. 9 is a perspective view of the upper handle device 10U constituting the handle device 1 as seen obliquely from above the door 100. Fig. 10 is an enlarged perspective view showing the torsion spring 33 of the upper handle device 10U in Fig. 9. Fig. 11 is an enlarged perspective view showing the torsion spring 33 and the spring support portion 271 of the upper handle device 10U.

[0023] The torsion spring 33 biases the base end 252 of the handle arm 25 on which the operating piece 31 is provided in the direction of arrow A, which is the rotation direction of the handle arm 25. The torsion spring 33 has a coil portion 332 between one end 331 and the other end 333. The coil portion 332 has an annular portion through which the pin 28 can be inserted. The torsion spring 33 is supported by the pin 28 by inserting the pin 28 into the coil portion 332. The one end 331 is supported by a spring support portion 271 of the indoor base 27.

[0024] The spring support portion 271 is formed by, for example, bending a metal material into a curved shape by pressing it. Since the surface of the spring support portion 271 that supports the one end portion 331 is formed into a curved shape, it is possible to prevent the one end portion 331 of the torsion spring 33 from rubbing against and deteriorating when the handle device 1 is used for a long period of time.

[0025] The other end 333 is engaged with the handle arm 25. The other end 333 is engaged with, for example, a support pin 34 that supports the handle arm 25 on the indoor base 27. The other end 333 may be indirectly supported on the handle arm 25 via the support pin as described above, or may be directly supported on the handle arm 25 without the support pin 34. The support pin 34 is supported in a state where it is received in an elongated pin receiving portion 29 provided in the indoor base 27 to ensure the amount of rotation of the handle arm 25 with respect to the indoor base 27.

[0026] Fig. 12 is an enlarged rear view showing the operation piece 31 of the handle device 1 and the operated piece 1009 of the latch lock 1000. Fig. 13 is an enlarged rear view showing the contact state between the operation piece 31 of the handle device 1 and the operated piece 1009 of the latch lock 1000.

[0027] When the handle arm 25 rotates, the operating piece 31 moves the operated piece 1009 of the latch lock 1000 via the operating piece main body 311, thereby disengaging the latch bolt 1110 of the latch lock 1000. The operating piece 31 is formed, for example, by pressing a metal material. The operating piece 31 has a contact surface 312 with the operated piece 1009, the thickness of which is the direction in which the die is removed during press working. The contact surface 312 is curved. This is because a curved sag (contact surface 312) is formed on the upstream side of the die removal direction, and a pointed burr 312a is formed on the downstream side of the die removal direction.

[0028] The operated piece 1009 of the latch lock 1000 has a contacted surface 1009a that is pressed by the contact surface 312 of the operating piece 31 of the handle device 1. The contacted surface 1009a is part of a surface 1009b that has an angle θ with respect to the thickness direction (the z-axis direction shown in Figures 12-13) of the contact surface 312. The angle of the surface 1009b that has the contacted surface 1009a can be set to any angle, as long as the burrs 312a do not come into contact with the contact surface 312, for example.

[0029] In the upper handle device 10U of the handle device 1, if the surface 1009b having the contact surface portion 1009a of the operated piece 1009 is perpendicular to the contact surface portion 312 of the operating piece 31, and if a burr 312a is present on the downstream side of the contact surface portion 312 of the operating piece 31 in the thickness direction, when the operating piece 31 contacts the contact surface portion 1009a and pushes the operated piece 1009, the burr 312a may come into contact with the contact surface portion 1009a and get caught on the contact surface portion 1009a, which may interfere with the pushing movement. In such a case, the burr 312a may also damage the contact surface portion 1009a. To avoid this, the burr 312a is an excess portion on the part, and it is necessary to perform processing on the mold, such as chamfering or chamfering, to prevent the burr 312a from occurring. However, such processing adds additional steps and increases costs.

[0030] In the upper handle device 10U, the surface 1009b having the contacted surface portion 1009a is a surface that has an angle θ with respect to the thickness direction of the contact surface portion 312, so that the contact surface portion 312 and the contacted surface portion 1009a come into line contact. In the upper handle device 10U, because the contact between the contact surface portion 312 and the contacted surface portion 1009a is line contact, even if there is a burr 312a in the thickness direction of the contact surface portion 312, it is possible to prevent the burr 312a from coming into contact with the contacted surface portion 1009a. Furthermore, as described above, because the contact surface portion 312 is formed into a curved surface, only the contact surface portion 312 comes into contact with and presses the contacted surface portion 1009a, and therefore the contacted surface portion 1009a is not damaged. Therefore, in the upper handle device 10U, the surface 1009b having the contacted surface portion 1009a is a surface having an angle θ with respect to the thickness direction of the contact surface portion 312, so that the door 100 can be opened and closed smoothly without processing such as processing the mold so that burrs 312a are not generated or removing the burrs 312a in a post-press process, thereby reducing the production cost of the handle device 1.

[0031] Figure 14 is a cross-sectional view of an upper handle device 10U in a modified example of the handle device 1 and the latch lock 1000. Unlike the upper handle device 10U attached to the left-hand door 100 described above, the upper handle device 10U shown in Figure 14 shows an example attached to a so-called right-hand door 100R in which a hinge (not shown) is located on the right side facing the interior surface 102R of the door 100R.

[0032] The handle device 1 described above can be used not only for the left-hand door 100 shown in FIG. 1 etc., but also for the right-hand door 100R shown in FIG.

[0033] [Latch lock configuration] Next, the configuration of the latch lock 1000 of the handle device 1 will be described.

[0034] Fig. 15 is an enlarged rear view showing the handle device 1 and the latch lock 1000. Fig. 16 is an enlarged rear view showing the latch lock 1000 with the latch lock cover 1001 attached. Fig. 17 is an enlarged rear view showing the latch lock 1000 with the latch lock cover 1001 removed.

[0035] As shown in Figures 15 to 17, the latch lock 1000, which constitutes part of the opening and closing device of the door 100, mainly comprises a latch lock cover 1001, a latch lock housing 1002, lock face side screws 1003, 1004, central side screws 1005, 1006, locking arms 1007, 1008, an operated piece 1009, a lock face 1010, a decorative panel 1010a, and a latch bolt assembly 1100.

[0036] The latch lock lid 1001 is a lid that covers an opening 1015 provided on one side of the latch lock housing 1002 in the indoor / outdoor direction (y-axis direction), in this embodiment on the outdoor side, to close the opening 1015. The latch lock lid 1001 is fastened by threading lock face side screws 1003, 1004 and center side screws 1005, 1006 into the latch lock housing 1002, respectively.

[0037] The latch lock housing 1002 is a box-shaped housing that houses the components of the latch lock 1000, including those described above, in a storage space formed inside. When the latch lock housing 1002 is attached to the door 100, the lock face 1010 and the decorative panel 1010a are attached to the side surface 103 so that the latch bolt 1110 of the latch bolt assembly 1100 protrudes from the side surface 103 on the side where the handle device 1 is attached to the door 100 (the right side in the x-axis direction in this embodiment).

[0038] The latch lock housing 1002 has lock face-side screw holes 1011 and 1012 and central-side screw holes 1013 and 1014. The lock face-side screw holes 1011 and 1012 are formed in a lock face-side lid receiver 1016 bent from the upper side surface 1002a of the latch lock housing 1002 toward the opening 1015 (toward the lower side surface 1002b of the latch lock housing 1002), and in a lock face-side lid receiver 1017 bent from the lower side surface 1002b of the latch lock housing 1002 toward the opening 1015 (toward the upper side surface 1002a of the latch lock housing 1002). The central-side screw holes 1013 and 1014 are provided inside the latch lock housing 1002.

[0039] The lock surface side lid receiving portions 1016, 1017 are provided in positions close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b. By providing the lock surface side lid receiving portions 1016, 1017 in two locations, on the upper and lower sides, close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b, the strength of the latch lock housing 1002 near the lock surface 1010 can be increased. Furthermore, by configuring the latch lock housing 1002 in this manner, the latch lock lid 1001 can be prevented from floating even when a strong force is applied to the latch lock 1000 from the indoor / outdoor direction. Note that if the lid receiving portion is provided on the lock surface 1010, there is not enough space to provide sufficient reinforcement, and rigidity is reduced compared to when it is provided in positions close to the lock surface 1010 on the upper side surface 1002a and the lower side surface 1002b.

[0040] As shown in FIG. 15, the latch lock 1000 is fixed to the side surface 103 of the door 100 via a lock face 1010 and a decorative plate 1010a.

[0041] The locking arms 1007 and 1008 are pivotally supported by central screw holes 1013 and 1014, and are rotatable about the central screw holes 1013 and 1014, which serve as fulcrums.

[0042] The locking arm 1007 is provided on the upper side in the height direction of the door 100. A locking protrusion 1018 that protrudes downward is provided at the end of the locking face side of the locking arm 1007. The latch bolt 1110 is locked via this locking protrusion 1018, preventing the latch bolt 1110 from rotating. In addition, an engagement protrusion 1021 is provided at the end of the center side of the locking arm 1007 to connect and operate the locking arm 1007 with the locking arm 1008.

[0043] The locking arm 1008 is provided on the lower side in the height direction of the door 100. A locking projection 1019 that projects downward is provided at the end of the locking face side of the locking arm 1007. A latch bolt 1110 is locked via this locking projection 1019, preventing the latch bolt 1110 from rotating. An operated piece 1009 that is a device separate from the latch lock 1000 and can come into contact with an operating piece 31 provided on a handle device 1 that constitutes a part of the opening and closing device is provided at the end of the center of the locking arm 1008. The provided operated piece 1009 allows the locking arm 1008 and the locking arm 1007 to rotate about the central screw holes 1013, 1014 in response to the operation of the handle arm 25 to which the operating piece 31 is fixed. When the locking arms 1007 and 1008 rotate, the above-mentioned lock between the locking projections 1018 and 1019 and the latch bolt 1110 is released, and the latch bolt 1110 becomes rotatable.

[0044] An engagement hole 1020 is provided at the end on the central side of each of the locking arms 1007 and 1008, which receives an engagement protrusion 1021 for operating the locking arms 1007 and 1008 while the locking arms 1007 and 1008 are connected. When the engagement protrusion 1021 is received in the engagement hole 1020, the locking arms 1007 and 1008 move together, and as the locking arm 1007 rotates around the central screw hole 1013, the locking arm 1008 rotates around the central screw hole 1014. As a result, the latch bolt 1110 is released from engagement by the locking protrusions 1018 and 1019, and the latch bolt 1110 becomes rotatable. It is not necessary for the locking arms 1007 and 1008 to be connected by a protrusion such as the engaging protrusion 1021, and the locking arms 1007 and 1008 may be connected, for example, by inserting a shaft member with a retaining mechanism into holes formed in both the locking arms 1007 and 1008.

[0045] In the latch lock 1000, the latch bolt assembly 1100 is detachable from the latch lock housing 1002. The latch bolt assembly 1100 has a latch bolt 1110. As described above, the latch bolt 1110 protrudes from the latch lock housing 1002, and fits into a receiving portion (recess) of the door frame when the door 100 is closed. When the door 100 is opened or closed, the latch bolt 1110 is pressed by the door frame and temporarily retreats into the latch lock housing 1002, and protrudes from the latch lock housing 1002 when the pressing force from the door frame side is no longer acting.

[0046] Fig. 18 is a perspective view showing a latch bolt assembly 1100 of the latch lock 1000. Fig. 20 is an exploded perspective view showing a latch case 1120, latch bolt 1110, coil spring 1140, and pressing member 1130 of the latch bolt assembly 1100. Fig. 21 is a perspective view of the latch bolt 1110.

[0047] As shown in FIGS. 19 and 20, the latch bolt assembly 1100 of the latch lock 1000 is configured by assembling a latch bolt 1110, a coil spring 1140, and a pressing member 1130 to a latch case 1120.

[0048] As shown in Figures 19 to 21, the latch bolt 1110 is an inverted latch. The latch bolt 1110 has a closing contact portion 1111, an engaging protrusion 1112, an inner surface portion 1113, a rotation restriction portion 1119, and an opening contact portion 1114. The closing contact portion 1111 and the opening contact portion 1114 are provided on the right side (the side protruding in the x-axis direction) of the latch bolt 1110. The closing contact portion 1111 comes into contact with the door frame when the door 100 is closed. The opening contact portion 1114 comes into contact with the door frame when the door 100 is opened. Both the closing contact portion 1111 and the opening contact portion 1114 have flat or approximately flat surfaces, and form an acute angle when viewed from the top and bottom.

[0049] A pressed portion is provided inside the closing contact portion 1111 and the opening contact portion 1114 of the latch bolt 1110. The pressed portion is a portion where the latch bolt 1110 is pressed by the coil spring 1140 via the pressing member 1130. When the pressed portion is pressed, the latch bolt 1110 protrudes from the latch case 1120 (latch lock housing 1002, door 100).

[0050] The inner surface portion 1113 has a shape in which a flat surface or a substantially flat surface extending in the vertical direction on the indoor side of the latch bolt 1110 protrudes in the vertical direction. The rotation restricting portion 1119 is located on the outdoor side of the inner surface portion 1113 in the z-axis direction and has a shape in which it protrudes in a manner generally similar to that of the inner surface portion 1113. When the latch bolt 1110 is housed in the latch case 1120, the inner surface portion 1113 and the rotation restricting portion 1119 each face the inner surface of a side wall portion 1124 on the indoor side, which will be described later. When the latch bolt 1110 is housed in the latch case 1120 and in the protruding position, the portions of the inner surface portion 1113 and the rotation restricting portion 1119 that protrude in the vertical direction contact the inner surface of a pillar portion 1121, which will be described later. The rotation of the inner side surface portion 1113 and the rotation restricting portion 1119 is restricted by the locking projections 1018, 1019, so that the latch bolt 1110 is locked as described above, and the latch bolt 1110 is prevented from rotating.

[0051] The inclined surface portion 1115 is a surface that is parallel or approximately parallel to the closing contact portion 1111 provided on the central side of the latch bolt 1110.

[0052] The opening contact portion 1114 intersects and is continuous with the closing contact portion 1111 and the inclined surface portion 1115. The closing contact portion 1111 intersects and is continuous with the opening contact portion 1114 and the inner surface portion 1113. In other words, when the latch bolt 1110 is viewed from above and below, the closing contact portion 1111, the inner surface portion 1113, the opening contact portion 1114, and the inclined surface portion 1115 form the four sides of a rhombus.

[0053] The engaging protrusion 1112 is provided on the outdoor side of the latch bolt 1110, near the apex between the central end of the opening contact portion 1114 and the outdoor end of the inclined surface portion 1115. The engaging protrusion 1112 protrudes vertically, similar to the vertically protruding portion of the inner surface portion 1113. In this embodiment, the outdoor-side edge of the engaging protrusion 1112 is rounded and chamfered. As described above, the latch bolt 1110 becomes rotatable when the rotation restricting portion 1119 of the latch bolt 1110 is released from the engagement by the locking projections 1018, 1019. At this time, the latch bolt 1110 rotates around the engaging protrusion 1112 as a central axis. However, by rounding and chamfering the outdoor-side edge of the engaging protrusion 1112, the engaging protrusion 1112 can easily roll on the pillar portion 1121 and guide portion 1122 of the latch case 1120. The engaging protrusion 1112 may be formed in a cylindrical shape.

[0054] 20, the latch case 1120 is a member whose external shape is formed into a substantially rectangular parallelepiped shape. The latch case 1120 is configured by integrally molding a pillar portion 1121, a guide portion 1122, a spring accommodating portion 1123, and a side wall portion 1124 from a resin material, and a space for accommodating the latch bolt 1110 and the like is formed inside the latch case 1120.

[0055] The pillar portion 1121 is a pillar-shaped portion that is provided on the lock face 1010 side of the latch lock 1000 and extends in the short direction of the side surface 103 of the door 100, i.e., in the indoor / outdoor direction (y-axis direction). When the latch bolt 1110 is in the protruding position, the pillar portion 1121 functions as a retaining portion that retains the latch bolt 1110 by abutting the engaging protrusion 1112 of the latch bolt 1110 with the inner side surface portion 1113 and the rotation restricting portion 1119.

[0056] A pair of side walls 1124 are provided on the indoor and outdoor side surfaces of the latch case 1120. A groove-shaped guide portion 1122 for guiding the latch bolt 1110 is formed on the inside of each of the indoor and outdoor side walls 1124 (the side where the latch bolt 1110 and the like are accommodated).

[0057] The spring accommodating section 1123 is provided at the center of the latch case 1120. The indoor and outdoor sides of the spring accommodating section 1123 are molded integrally with the respective side wall sections 1124. The spring accommodating section 1123 is formed in a cylindrical or approximately cylindrical shape at the vertical center so as to cover the end of the coil spring 1140 and the outer periphery surrounding it, thereby supporting the end of the coil spring 1140. The spring accommodating section 1123 is molded integrally with the side wall section 1124 by a columnar portion extending from the cylindrical or approximately cylindrical portion to the side wall section 1124 in the indoor / outdoor direction. Because the spring accommodating section 1123 is formed in this manner, the latch case 1120 has open sides in the vertical direction (z-axis direction) and the left side in the horizontal direction (x-axis direction), i.e., the top and bottom sides.

[0058] The pressing member 1130 is formed in a substantially rectangular parallelepiped shape. The pressing member 1130 has a flat surface on the lock face 1010 side, and presses the pressed portion of the latch bolt 1110. The pressing member 1130 is also formed so that the center side can receive the end of the coil spring 1140.

[0059] As shown in FIG. 20 , the latch bolt assembly 1100 has a spring accommodating portion 1123 integrally molded with the latch case 1120, and the top, bottom, and left sides of the latch case 1120 are open. Therefore, when assembling the latch bolt assembly 1100, the latch bolt 1110 can be inserted from the top and bottom sides as indicated by arrow A1, the pressing member 1130 as indicated by arrow A2, and the coil spring 1140 as indicated by arrow A3. In other words, the latch bolt 1110 integrates the latch case 1120 and the spring accommodating portion 1123 to reduce the number of parts and costs, and simplifies assembly by allowing components to be inserted and assembled from the sides. In particular, the latch lock 1000 requires the orientation of the latch bolt 1110 to be changed depending on the door opening direction (opening direction) of the door 100.

[0060] According to the latch bolt assembly 1100 described above, components such as the latch bolt 1110 can be easily attached to and detached from the latch case 1120, and a user such as an installer of the door 100 can easily change the orientation of the latch bolt 1110 to suit the door 100. Furthermore, by providing the spring accommodating portion 1123 in the latch case 1120, the latch bolt assembly 1100 can prevent components from falling off when they are removed.

[0061] Although arrows A1 to A3 in FIG. 20 show latch bolt 1110, pressing member 1130, and coil spring 1140 being inserted from below, these members can also be inserted from above.

[0062] FIG. 18 is a cross-sectional view of the latch lock taken along line BB in FIG. 16, viewed from one side in the x-axis direction.

[0063] 20 and 21, in the latch bolt assembly 1100 of the latch lock 1000, the engaging protrusion 1112 of the latch bolt 1110 is formed in a columnar or approximately columnar shape extending in the vertical direction. Therefore, as shown in Fig. 18, when the latch bolt 1110 is in the protruding position, the engaging protrusion 1112 prevents interference with the locking protrusions 1018, 1019 of the locking arms 1007, 1008, and can prevent damage to the engaging protrusion 1112 even when a high load is applied to the latch lock 1000.

[0064] In addition, those skilled in the art can appropriately modify the present invention in accordance with conventionally known knowledge. As long as such modifications still comprise the structure of the present invention, they are of course included in the scope of the present invention. [Explanation of symbols]
