Description

[Technical Field]

[0001] The present invention relates to a lock mounting structure in which a lock is mounted on a vertical frame of a door body. [Background technology]

[0002] A conventional technique is known in which a metal lock is placed in a notch formed in the frame (vertical stile) of a sash door, and the lock is then attached directly to a base formed in the frame (see Patent Document 1). The side of the frame where the notch is formed is recessed, and a portion of the side is bent to form the base. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 60-022157 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, the sash door frame on the door edge side is provided with an edge material that covers the space between the sash door frame and the door frame, and the edge material makes it difficult for rainwater and other liquids to blow in between the sash door frame and the door frame. On the other hand, gates do not have the above-mentioned configuration, so for example, if the technology described in Patent Document 1, in which the lock is attached directly to the base of the frame, is used on a gate, water running down the frame may enter the frame between the lock and the frame, and the water that has entered may wet the metal lock, so it is desirable to stop this water from entering.

[0005] An object of the present invention is to provide a lock mounting structure that uses a water-stopping member to reduce the risk of water entering between the lock and the vertical frame and wetting the lock. [Means for solving the problem]

[0006] The lock mounting structure of the present invention is a lock mounting structure for a gate having a door body with a stile, in which a lock is mounted to the stile, the stile having a pair of visible surface portions, an inner peripheral visible surface portion and an outer peripheral visible surface portion, and a concave groove portion formed by the outer peripheral visible surface portion and a pair of side portions extending from the outer peripheral visible surface portion, the pair of visible surface portions, the inner peripheral visible surface portion and the outer peripheral visible surface portion forming a hollow portion, an opening into which the lock is inserted is formed in the outer peripheral visible surface portion, the lock comprising a lock case inserted into the hollow portion from the opening, and a lock case extending below the bottom surface of the lock case and attached to the outer peripheral visible surface portion at a position below the opening The lock case has a lower mounting portion that is attached to the lock case, and an upper mounting portion that extends above the top surface of the lock case and is attached to the outer peripheral projected surface portion at a position above the opening, and a water-stopping member that stops water from flowing between the upper mounting portion and the outer peripheral projected surface portion is arranged in the groove portion, and the water-stopping member has a water-stopping main body portion that is arranged between the upper mounting portion and the outer peripheral projected surface portion, an upper edge water-stopping portion that protrudes from the water-stopping main body portion in the visible direction of the vertical frame and is arranged along the upper edge of the upper mounting portion, and a pair of side edge water-stopping portions that protrude from the water-stopping main body portion in the visible direction of the vertical frame and are arranged along both side edges of the upper mounting portion. [Effects of the Invention]

[0007] According to the present invention, a lock mounting structure can be provided that uses a water-stopping member to reduce the risk of water entering between the lock and the vertical frame and wetting the lock. [Brief explanation of the drawings]

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2, gate 1, which is the structure on which the lock mounting structure of this embodiment is configured, is a double-swing gate that separates the road side from the property side, and includes a pair of left and right gateposts 2 erected on the ground, and a pair of door bodies 3A, 3B that are supported so as to be able to open and close on the pair of left and right gateposts 2. Door bodies 3A, 3B are assembled vertically, including an upper frame 31, a lower frame 32, a door-end stile 33, and a hanging base stile 34, and multiple lattice members or surface members (not shown) attached to the upper frame 31 and the lower frame 32. Gatepost 2, upper frame 31, lower frame 32, door-end stile 33 (stile), and hanging base stile 34 are each composed of an integrally extruded aluminum shaped member. The hanging stile 34 of door body 3A is connected to one of the left and right gateposts 2 via a hinge 4, and the hanging stile 34 of door body 3B is connected to the other gatepost 2 via a hinge 4. A lock 5 such as a cylinder lock is attached to door body 3A, and a lock receiver 8 is attached to door body 3B, with the lock 5 and lock receiver 8 constituting a locking device 10. A drop lock 11 is attached to the lower end of the door end stile 33 of door body 3B. In the following description, the left-right direction of the gate 1 is the X-axis direction, the up-down direction of the gate 1 is the Y-axis direction, and the projection direction of the gate 1 is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] As shown in Figures 3 to 5, the door end vertical frame 33 of the door body 3A has a pair of sighting surfaces, namely a road-side sighting surface 331 and a site-side sighting surface 332, an inner peripheral sighting surface 333, an outer peripheral sighting surface 334, and a groove portion 36 formed by the outer peripheral sighting surface 334 and a pair of side portions 335, 336 extending from the outer peripheral sighting surface 334, and a hollow portion 35 along the Y-axis direction is formed by the pair of sighting surfaces 331, 332, the inner peripheral sighting surface 333, and the outer peripheral sighting surface 334. The outer peripheral projection surface 334 has a vertically elongated rectangular opening 37 into which a lock case 6 of the lock 5, which will be described later, is inserted. The side portions 335 and 336 are each formed in an L-shape, having a side plate portion 337 aligned along the X-axis direction and a leading plate portion 338 that is bent from the side plate portion 337 toward the opening 37 and shaped along the Z-axis direction. The side plate portions 337 extend outward in the X-axis direction from both side edges of the outer peripheral projection surface 334 aligned along the Y-axis direction, and the leading plate portion 338 of the side portion 335 is bent toward the site in the Z-axis direction, and the leading plate portion 338 of the side portion 336 is bent toward the road in the Z-axis direction. The side plate portion 337 and front plate portion 338 of the side portion 335 and the outer peripheral projection surface portion 334 form a concave end groove portion 38A that opens on the site side (opening 37 side) in the Z-axis direction, and the side plate portion 337 and front plate portion 338 of the side portion 336 and the outer peripheral projection surface portion 334 form a concave end groove portion 38B that opens on the road side (opening 37 side) in the Z-axis direction. In addition, end caps 39 that hide the edges of the end stile 33 are attached to the upper and lower ends of the end stile 33, and the end caps 39 cover the hollow portion 35 and groove portion 36 of the end stile 33.

[0011] As mentioned above, the locking device 10 is composed of the lock 5 and the lock receiver 8. Although not shown, the lock receiver 8 is equipped with a lock front and a lock receiver box that are attached to the door end vertical frame 33 of the door body 3B, and when the gate 1 is closed, a latch bolt 53 and a deadbolt 54, which will be described later, are arranged in the lock receiver box so that they can be protruded and retracted. 3 to 5, the lock 5 includes a lock front 7 and a lock case 6. The lock case 6 includes a key portion 51, a handle 52, a latch bolt 53, a deadbolt 54, and the like. The lock front 7 is made of stainless steel and is formed in the shape of a vertically long rectangular plate, with holes 71 formed therein through which the latch bolt 53 and deadbolt 54, which will be described later, protrude. The lock front 7 is arranged along a case front plate portion 61, which will be described later, and is attached to the lock case 6 with screws 14, which serve as fasteners. An outer surface 72 of the lock front 7 along the Z-axis direction is arranged flush with outer surfaces 338A, which are the ends of a pair of side portions 335, 336. The lock case 6 is made of stainless steel and has a case front plate 61 arranged along the outer peripheral projection surface 334, and a case main body 62. The case front plate 61 is formed with an upper mounting portion 55 extending above the upper surface of the case main body 62 and a lower mounting portion 56 extending below the lower surface of the case main body 62. The upper mounting portion 55 and the lower mounting portion 56 are attached to the outer peripheral projection surface 334 with screws 13 as fasteners. In this attached state, the upper mounting portion 55 is positioned above the opening 37, and the lower mounting portion 56 is positioned below the opening 37, with the case front plate 61 and the lock front 7 positioned in the recessed groove 36. The case main body 62 is arranged in the hollow portion 35 and is inserted into the hollow portion 35 through the opening 37.

[0012] A water-stopping member 9 that stops water from entering between the upper mounting portion 55 and the outer periphery projection surface 334 is disposed in the recessed groove portion 36. The water-stopping member 9 is made of an elastic rubber packing. A liner 12 that maintains an appropriate distance between the outer periphery projection surface 334 and the lower mounting portion 56 is also disposed between them. Another liner (not shown) may also be disposed between the water-stopping member 9 and the upper mounting portion 55. As shown in FIG. 6 , the water-stopping member 9 includes a water-stopping main body 91 disposed between the upper mounting portion 55 and the outer peripheral projection surface 334, an upper edge water-stopping portion 99 protruding from the water-stopping main body 91 in the X-axis direction and disposed along the upper edge of the upper mounting portion 55, and a pair of side edge water-stopping portions 94, 95 protruding from the water-stopping main body 91 in the X-axis direction and disposed along both side edges of the upper mounting portion 55. The water-stopping member 9 also includes extension portions 96, 97 extending further downward from the lower ends of the side edge water-stopping portions 94, 95. In this water-stopping member 9, the water-stopping main body 91, the upper edge water-stopping portion 99, and the side edge water-stopping portions 94, 95 form a space in which the upper mounting portion 55 is disposed. The side edge water-stopping portions 94, 95 fit into the end grooves 38A, 38B, respectively, and abut against and cover both side edges of the upper mounting portion 55. The water-stopping main body 91 is a generally rectangular plate and extends in the Y-axis direction from the position of the upper edge water-stopping portion 99 to the position of the screw 13 that attaches the upper mounting portion 55 to the outer peripheral projection surface 334. The water-stopping main body 91 further extends below the position of the screw 13 and above the case main body 62. The width of the water-stopping main body 91 in the Z-axis direction is greater than the width of the opening 37 in the Z-axis direction. The water-stopping main body 91 is formed with a hole 98 through which the screw 13 is inserted. The extension portions 96 and 97 are positioned below the lower edge of the water-stopping main body 91 and extend below the top surface of the case main body 62 to the position of the screw 14 that attaches the lock front 7 to the lock case 6. The extension portions 96 and 97 also have tapered surfaces 961 and 971 that connect their lower surfaces to the side surfaces on the side plate 337 side. The extensions 96 and 97 also have tapered surfaces that connect the lower surfaces and the front surfaces (surfaces on the outer periphery side). The upper edge water stopping portion 99 protrudes from the upper edge of the water stopping main body portion 91, and protrudes further in the X-axis direction than the side edge water stopping portions 94, 95. The width dimension of the upper edge water stopping portion 99 in the Z-axis direction is roughly the same as the width dimension between the tip surfaces of the tip plate portions 338 of the pair of side portions 335, 336, and it stops water from flowing between these end surfaces at a position above the upper mounting portion 55. This upper edge water stopping portion 99 abuts against the upper edges of the upper mounting portion 55 and the lock front 7, and covers them from above.

[0013] The gate 1 described above has a lock mounting structure 100 formed by attaching the lock case 6 and lock front 7 to the leading stile 33 of the gate 1 and arranging the water-stopping member 9 in the recessed groove 36 as described above. The gate 1 of this embodiment has this lock mounting structure 100, which prevents water such as rainwater from entering the hollow portion 35 of the leading stile 33 as follows. First, when rainwater flows down along the door end vertical frame 33, the water-stopping main body 91, which is sandwiched between the upper mounting part 55 and the outer peripheral projection surface part 334, prevents rainwater from entering between the upper mounting part 55 and the outer peripheral projection surface part 334. In addition, the upper edge water stopping portion 99 arranged along the upper edge of the upper mounting portion 55 covers and abuts against the upper edge, thereby preventing rainwater from entering between the upper edge of the upper mounting portion 55 and the upper edge water stopping portion 99. Furthermore, the side edge water stopping parts 94, 95 arranged along both side edges of the upper mounting part 55 cover and abut the both side edges, thereby preventing rainwater from entering between the both side edges of the upper mounting part 55 and the side edge water stopping parts 94, 95. In addition, rainwater flowing down along the joint between the front panel portion 338 and the lock front 7 is guided downward by the extension portions 96, 97 and continues to flow downward, preventing rainwater from entering the hollow portion 35 of the door end vertical frame 33 through the opening.

[0014] [Variations] In the above embodiment, the waterproofing member 9 is made of an elastic rubber packing, but it may be made of a foam material such as sponge, or any material that is not elastic but can still stop water. In the above embodiment, the water-stopping main body 91 is formed to extend in the Y-axis direction at least from the position of the upper edge water-stopping portion 99 to the position of the screw 13 that attaches the upper mounting portion 55 to the outer peripheral projected surface portion 334, and is formed with a hole 98 through which the screw 13 is inserted.However, as long as the water-stopping main body 91 is configured to be able to prevent water from flowing down from above between the upper mounting portion 55 and the outer peripheral projected surface portion, the water-stopping main body 91 may be formed to be shorter than the length in the Y-axis direction between the position of the upper edge water-stopping portion 99 and the position of the screw 13 that attaches the upper mounting portion 55 to the outer peripheral projected surface portion 334. In the above embodiment, the extension portions 96, 97 that extend further downward from the lower ends of the side edge water-stopping portions 94, 95 are arranged to extend downward to the position of the screws 14, but they do not have to extend to the position of the screws 14. Furthermore, if sufficient water-stopping properties can be obtained without the extension portions 96, 97, the configuration of the extension portions 96, 97 may be omitted. In the above embodiment, tapered surfaces 961, 971 are formed on the extension portions 96, 97, allowing the water-stopping member 9 to be more smoothly slidably inserted into the recessed groove portion 36 from the upper end of the door-end stile 33, but the tapered surfaces 961, 971 may be omitted if the water-stopping member 9 is slidably inserted without the tapered surfaces 961, 971. Furthermore, when the extension portions 96, 97 are omitted, the tapered surfaces 961, 971 may be formed on the side edge water-stopping portions 94, 95.

[0015] In the above embodiment, the pair of side portions 335, 336 have the front plate portions 338, but this configuration may be omitted. In this case, the outer surface 72 of the lock front 7 is positioned flush with the ends of the side plate portions 337 of the pair of side portions 335, 336. In the above embodiment, the lock front 7 is a separate member from the lock case 6 and is superimposed on the case front plate portion 61, but it may also be formed integrally with the case front plate portion 61. In the above embodiment, the gate 1 is of a double swing type, but it may also be of a single swing type.

[0016] [Summary of the invention] The lock mounting structure of the present invention is a lock mounting structure for a gate having a door body with a stile, in which a lock is mounted to the stile, the stile having a pair of visible surface portions, an inner peripheral visible surface portion and an outer peripheral visible surface portion, and a concave groove portion formed by the outer peripheral visible surface portion and a pair of side portions extending from the outer peripheral visible surface portion, the pair of visible surface portions, the inner peripheral visible surface portion and the outer peripheral visible surface portion forming a hollow portion, an opening into which the lock is inserted is formed in the outer peripheral visible surface portion, the lock comprising a lock case inserted into the hollow portion from the opening, and a lock case extending below the bottom surface of the lock case and attached to the outer peripheral visible surface portion at a position below the opening The lock case has a lower mounting portion that is attached to the lock case, and an upper mounting portion that extends above the top surface of the lock case and is attached to the outer peripheral projected surface portion at a position above the opening, and a water-stopping member that stops water from flowing between the upper mounting portion and the outer peripheral projected surface portion is arranged in the groove portion, and the water-stopping member has a water-stopping main body portion that is arranged between the upper mounting portion and the outer peripheral projected surface portion, an upper edge water-stopping portion that protrudes from the water-stopping main body portion in the visible direction of the vertical frame and is arranged along the upper edge of the upper mounting portion, and a pair of side edge water-stopping portions that protrude from the water-stopping main body portion in the visible direction of the vertical frame and are arranged along both side edges of the upper mounting portion. According to the lock mounting structure of the present invention, the water-tight main body is positioned between the upper mounting portion and the outer peripheral projected surface portion, the upper edge water-tight portion protruding from the water-tight main body is positioned along the upper edge of the upper mounting portion, and a pair of side edge water-tight portions protruding from the water-tight main body is positioned along both side edges of the upper mounting portion, so that water flowing down from above is stopped by the water-tight member, reducing the risk of water entering the hollow portion of the vertical frame between the upper mounting portion and the outer peripheral projected surface portion and wetting the lock case. Furthermore, since the water-stopping main body is positioned between the upper mounting portion and the outer peripheral projected surface portion, rather than between the lower mounting portion and the outer peripheral projected surface portion, even when various types of locks each having different lock cases are used, there is no need to prepare a dedicated water-stopping member for each lock, thereby improving the versatility of the water-stopping member.

[0017] In the lock mounting structure of the present invention, the pair of side portions each have a side plate portion that runs along the viewing direction and a front plate portion that bends from the side plate portion toward the opening and has a shape that runs along the viewing direction, and the side plate portion, the front plate portion, and the outer peripheral viewing surface portion form an end groove portion, and the side edge water-stopping portion may be fitted into each of the end groove portions. With this configuration, fitting the side edge water stop parts into the end grooves eliminates the formation of empty spaces in the end grooves, preventing water from flowing through the end grooves and trickling down the bottom of the water stop member. Furthermore, by sliding the water stop member into place from the end of the vertical stile, it is less likely to come off in the visible direction, improving workability.

[0018] In the lock mounting structure of the present invention, the upper mounting portion is mounted to the outer peripheral projected surface portion by a fixing device, and the water-stopping main body portion is formed to extend in the vertical direction at least from the position of the upper edge water-stopping portion to the position of the fixing device that mounts the upper mounting portion to the outer peripheral projected surface portion, and may have a hole through which the fixing device is inserted. With this configuration, for example, by inserting the fastener that attaches the upper mounting part to the outer peripheral projection surface part into the hole in the watertight main body part, the watertight member can be prevented from slipping out upward. Also, by applying pressure from the upper mounting part that is attached to the outer peripheral projection surface part by the fastener, the watertight main body part can function as a kind of liner to adjust the thickness in the projection direction.

[0019] In the lock mounting structure of the present invention, an extension portion is formed that extends further downward from the lower end of the side edge water-stopping portion, and the extension portion may be positioned at a position lower than the position of the lower edge of the water-stopping main body portion. With this configuration, for example, if there were no extension portion, there would be a risk that water attempting to enter between the vertical frame and the water-stopping member would travel from the side edge water-stopping portion along the lower edge of the water-stopping main body portion and enter the hollow portion of the vertical frame through the opening.However, by forming an extension portion, the aforementioned water will flow downward along the extension portion, further reducing the risk of water entering the hollow portion of the vertical frame through the opening.

[0020] In the lock mounting structure of the present invention, the extension portion may have a tapered surface that connects its lower surface to a side surface on the side plate portion side. According to this configuration, by configuring the tapered surface as described above, it is possible to improve the ease of insertion when sliding the water-stopping member into the end of the vertical frame.

[0021] In the lock mounting structure of the present invention, the lock case has a case front panel portion arranged along the outer peripheral visible surface portion, the upper mounting portion and the lower mounting portion are formed on the case front panel portion, the lock has a lock front arranged along the case front panel portion, and the outer surface of the lock front along the visible direction may be arranged flush with the ends of the pair of side portions. With this configuration, the design of the vertical frame can be improved by making the surfaces flush as described above. [Explanation of symbols]
