[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a strike device for engaging a sickle piece suitable for a sliding door provided with a sickle piece.
[0002]
[Prior art]
FIG. 15 is an explanatory diagram showing one of the reasons why the appearance of the present invention is expected. As shown in FIG. 15A, a certain clearance (for example, 3 mm, 5 mm, etc.) 55 is set between the front surface of the front plate 52 on the sliding door 51 side and the vertical frame 54 of the door frame 53. . As shown in (a) of FIG. 15, if the clearance on the upper side of the side end of the sliding door 51 and the clearance on the lower side of the side end are, for example, “about 5 mm each”, there is no distortion in the installation, So-called normal. However, even in this case, when the vertical direction of the sickle piece 57 with respect to the strike 56 attached to the vertical frame 54 is poor, the plurality of pulleys 58, 58 provided at the lower end of the sliding door 51 It is necessary to adjust the height appropriately.
[0003]
Further, even if the door frame 53 is not distorted and is normal at first, while the sliding door 1 has been used for a long time, for example, as shown in FIG. When the door frame is deformed like a parallelogram, the sickle piece 57 does not mesh well with the hooking portion of the strike 56. Therefore, it is necessary to arbitrarily adjust the height of the pulley and to slightly tilt the sliding door 51 forward or backward in response to the distorted door frame. In such a case, it is necessary to finely adjust the height of the front and rear pulleys, and depending on whether the height of the pulley is adjusted, the condition of the sickle piece 57 on the strike 56 becomes insufficient.
[0004]
[Problems to be solved by the invention]
In view of the above-described conventional problems, the first object of the present invention is to provide a sickle piece engaging strike device in which the degree of sickle hooking against the strike is good even if the door frame is somewhat distorted. It is. In particular, in the engagement relationship between the auxiliary strike and the sickle piece in the sliding door thickness direction, even if a so-called lateral displacement (lateral eccentricity) occurs, the tip of the sickle is sufficiently engaged. is there. Also, if the door frame is distorted from the beginning when the strike device is attached to the door frame, the height of the pulley becomes unnecessary by adjusting the vertical position of the auxiliary strike with respect to the troyoke in advance. To be able to.
[0005]
The second purpose is to use the strike body as it is by adjusting the fixed position of the auxiliary strike in the vertical direction with respect to Troyoke in some cases even if the parallelogram-like distortion of the door frame occurs. It is possible to do. The third object is that adjustment of the auxiliary strike with respect to the strike main body or trolley can be easily performed with a rational configuration. Another object of the present invention is to provide a strike device adapted to a sickle lock in which a sickle piece automatically rotates in an engagement direction when a collision hook of the sickle lock hits the door frame side when the sliding door is closed.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an explanatory diagram showing an environment for carrying out the invention. In FIG. 1, 1 is a sliding door, 2 is a front plate attached to a side end of the sliding door, and 3 is a lock box integrated with the front through a lock back plate 4 joined to the front plate 2. . The lock box 3 is provided with a sickle piece 5 having a finger-like (hook-like) tip 5a. The lock box 3 is provided with a locking / unlocking mechanism for locking the sickle piece 5 coming out of the front plate 2 (not shown here).
[0010]
By the way, the sliding door 1 is a sliding door on the one side of the summoning type when an article to which a strike device X for engaging with a sickle piece to be described later is attached is a “mating side sliding door”. Moreover, when the thing to which the strike apparatus X is attached is a "door frame", it becomes a sliding door with respect to the vertical frame of the door frame. In any case, the strike device X is incorporated in the cavity of the side edge of the mating sliding door or the vertical frame of the door frame so as to face the front plate 2 on the sliding door 1 side. In this embodiment, an example in which the strike device X is attached to the vertical frame 6 of the door frame will be described.
[0011]
As shown in FIG. 1, a certain clearance (for example, 3 mm, 5 mm, etc.) 7 is provided between the front plate 2 and the vertical frame 6 of the door frame. This is because, for example, the building door is distorted while the sliding door 1 is used for a long time, and as a result, the sickle piece 5 does not mesh well with the strike receiving portion.
[0012]
2 is a perspective view of the strike device X, FIG. 3 is an exploded perspective view of the strike device X, and FIGS. 4 to 13 are explanatory views of each member constituting the strike device X. FIG. Hereinafter, the constituent members will be described in order with reference to these drawings.
[0013]
A is a vertically long plate-shaped strike body, and the strike body A corresponds to a front plate facing the front plate 2 on the sliding door side. 6 and 7 are explanatory diagrams of the strike main body A. FIG. Reference numeral 10 denotes a screw (fixing tool) 11 hole formed at the upper and lower end portions of the strike body, and 12 denotes a T-shaped window portion formed between the screw holes 10 and 10 of the strike body. In this embodiment, the T-shaped window portion 12 communicates with the engagement window 13 and a rectangular wide engagement window 13 with which a sickle frame-shaped latching portion of the auxiliary strike B described below is engaged. And a narrow insertion window 14 into which the tip 5a of the sickle piece 5 enters.
[0014]
Reference numeral 15 shown in FIG. 3 is a pair of upper and lower cylindrical blocks interposed between the upper and lower ends of the strike main body A and upper and lower ear-shaped attachment portions of a troyoke C described later. The above-described screws 11 enter the penetrating state. Since the cylindrical block 15 is a member that sets a storage space for incorporating the auxiliary strike B between the strike main body A and the troyoke C, the outer wall shape is not particularly limited such as a square shape or a circular shape.
[0015]
B is an auxiliary strike, and this auxiliary strike B is engaged and disposed on the back side of the strike main body A so that the position can be adjusted in the vertical direction, and the distal end portion of the sickle piece 5 entered from the insertion window 14 of the strike main body A It plays a role as a hooking member for receiving 5a.
8 and 9 are explanatory diagrams of the auxiliary strike B. FIG. Referring to FIG. 8, reference numeral 16 denotes left and right vertical side walls. These vertical side walls 16 are shorter than the strike main body A as shown in FIG. 5, and when assembled into the strike main body A, the upper and lower cylindrical blocks 15 are arranged. , 15 is set so that a sufficient gap is formed.
[0016]
Reference numeral 17 denotes a planar U-shaped frame-shaped latching portion for a sickle piece protruding from a portion near the upper end of the front portion of the vertical side walls 16, 16. The width dimension W of the sickle piece latching portion 17 will be further described with reference to FIG. If a distortion occurs in the building, the distortion is an inclination in the thickness direction of the sliding door that intersects the traveling direction of the sliding door. In this case, when the width dimension W between the left and right opposing side walls 17a and 17a of the frame-shaped latching portion 17 has no allowance with respect to the thickness of the sickle piece 5, the sickle piece 5 will not mesh well with the frame-like latching portion 17.
[0017]
Therefore, in this embodiment, even if a so-called “lateral displacement (lateral eccentricity) state” occurs in the sliding door thickness direction engagement relationship between the auxiliary strike B and the sickle piece 5, the distal end portion of the sickle 5. The width dimension W of the frame-shaped latching portion 17 was set to be not less than 2 times to not more than 5 times the thickness of the sickle piece 5 so that 5a can be sufficiently engaged.
[0018]
The frame-shaped latching portion 17 engages so as to protrude from the wide engagement window 13 of the strike main body A as shown in FIGS. In this case, the tip 5a of the sickle piece 5 is engaged with the vertical wall 17b orthogonal to the left and right opposing side walls 17a and 17a of the frame-shaped latching portion 17, but the distortion of the construction is different from the lateral displacement. However, there is naturally a tilt in the height direction of the sliding door together with the horizontal shift, that is, a “so-called vertical shift (vertical eccentricity) state”. In this case, as described in the prior art section, the sliding door may be tilted in the front-rear direction in response to the distortion of the door frame. However, adjusting the height of the pulley is troublesome.
Therefore, in this embodiment, as shown in FIG. 5, the vertical dimension of the wide engagement window 13 of the strike main body A is set larger than that of the frame-shaped latching portion 17. Therefore, the required gaps 18 and 18 exist between the upper and lower sides of the frame-shaped latching portion 17 and the upper and lower edges of the wide engagement window 13.
[0019]
As described above, the front side (front side) of the vertical side walls 16 and 16 of the auxiliary strike B is formed with an end U-shaped latching portion 17 that engages with the strike main body A. A plurality of hook-shaped engaging portions 19 that engage with the trowel C are formed on the rear portions (rear side surfaces) of the side walls 16 and 16 so as to protrude.
[0020]
C is a trolley having a case part 20 having an opening on the front surface. The troy poke C has ear-shaped attachment parts 21 and 21 extending vertically from the case part 20, upper and lower cylindrical blocks 15 and 15, and screws 11 as fixing means. It is a fixing member integrated with the back surface of the strike main body A.
[0021]
10 and 11 are explanatory diagrams of Troyoke C. FIG. Referring to FIG. 10, 22 is a female screw hole formed in each of the upper and lower ear attachment parts 21, 21, and these female screw holes 22, 22 are screwed into the long hook-shaped screw 11.
Reference numeral 23 denotes left and right fixed side walls, and a fixed back surface 24 is connected to the rear end surfaces of these fixed side walls 23 and 23 in the intersecting direction. The fixed back surface 24 is provided with a plurality of holes in consideration of the engagement relationship with the auxiliary strike B and the position adjusting back plate D integrated with the auxiliary strike B.
[0022]
That is, 26 is a through hole formed in the upper part of the fixed back surface 24 and into which the stopper of the rectangular fixed back plate D enters. Reference numeral 27 denotes a vertical long hole for inserting a fixing tool formed in a lower portion of the fixed back surface 24. Reference numeral 28 denotes an adjustment slot for adjusting the vertical position of the auxiliary strike B. In the present embodiment, a total of four holes are formed corresponding to the protruding positions of the hook-like engagement portions 19 of the auxiliary strike B.
[0023]
Finally, D is a fixed back plate for position adjustment that is attached to the outer wall surface of the fixed back surface 24 of the troyoke C and is fixed to the fixed back surface 24 of the troyoke C together with the auxiliary strike B via the fixing tool 31. The fixed back plate D is arranged so that the vertical position of the auxiliary strike B is adjusted in consideration of the degree of engagement (the clearance described above) between the sickle piece 5 and the frame-like latching portion 17 at the time of locking. It is integrated with the auxiliary strike B and the fixed back surface 24. For this purpose, in this embodiment, as shown in FIGS. 12 and 13, there is a female thread portion 32 that coincides with the above-described vertical elongated hole 27 and into which the fixing tool 31 is screwed. Moreover, it has the back plate adjustment long hole 33 which coincides with the four adjustment long holes 28 mentioned above. Furthermore, the stopper 34 which enters the through-hole 26 described above is formed at the center of the upper end.
[0024]
The combination of each member in the above configuration will be described. When the disassembled state shown in FIG. 3 is changed to the combined state shown in FIG. 2, first, the hook-like engaging portion 19 of the auxiliary strike B is put into the adjustment long hole 28 of the troyoke C. Next, the hook-like engagement portion 19 is passed through the back plate adjustment long hole 33 of the fixed back plate D. At this time, the fixed back plate D is attached to the outer wall of the fixed back surface 24 of the auxiliary strike B by passing the stopper 34 through the through hole 26 regardless of the rear end. At this time, each hook-like engagement portion 19 of the auxiliary strike B engages with each of the adjustment long holes 28 and 33 of the troyoke C and the fixed back plate D. Therefore, if there is any fixing means, the auxiliary strike B is fixed to the fixed back plate. Cannot be removed from Troyoke C via D.
[0025]
Therefore, in consideration of the clearance 7 between the front 2 of the sliding door 1 and the vertical frame 6 of the door frame (in the case of a summing sliding door, the clearance with the counterpart sliding door), the position of the auxiliary strike B in the vertical direction with respect to Troyoke C is determined. adjust.
After that (after adjustment), the fixing tool 31 is inserted into the adjustment long hole 27 of the Troyoke C, and is screwed in a state matching the female thread portion 32 of the fixed back plate D. As a result, the auxiliary strike B, the trolley C, and the fixed back plate D are integrated into one member.
[0026]
Next, with the upper and lower cylindrical blocks 15 and 15 being interposed between the upper and lower ends of the strike body A and the upper and lower ear attachment portions of the troyoke C, the screw 11 is passed through the hole 10 of the strike body A, and the strike Main body A and Troyoke C are connected together.
[0027]
The strike device X of the present invention is unitized as shown in FIG. 2, and is mounted in the cavity of the vertical frame 6 of the door frame, for example, as shown in FIG. FIG. 1 is an example in which the clearance 7 is set to “about 5 mm”. In this case, the building is normal and the door frame is not distorted. When the door frame is not distorted, the tip portion 5a of the sickle piece 5 naturally engages with the frame-shaped latching portion 17 of the strike main body A.
[0028]
On the other hand, FIG. 14 shows a case where the door frame is distorted (the former) or has occurred (the latter). As apparent from FIG. 14, the strike body A is slightly inclined with respect to the distortion of the door frame with respect to the front 2 in the vertical state (here, for convenience of explanation, the strike body A is inclined backward by 2 degrees. I will decide).
In the case of the former, the hooking state of the sickle piece 5 with respect to the frame-shaped hooking portion 17 becomes defective in response to the distortion, so the screw 11 is loosened to remove the strike main body A from the troyoke C, and then fixed. After loosening the tool 31 and finely adjusting the position adjustment of the auxiliary strike B, the fixing tool 31 is tightened again, and the strike body A is fixed to the trolley C. In the latter case, the position of the auxiliary strike B with respect to the trolley C is adjusted and fixed in advance after inspecting the distortion of the vertical frame.
[0029]
【Example】
In the present embodiment, the window portion of the strike main body A is formed in a T-shape, but it may be a generally ordinary vertically long window. The fixed back plate D is a member for fixing the auxiliary strike B to the trolley C together with the fixing tool 31. The fixing method and form of the fixing back plate D can be arbitrarily changed.
[0030]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
(1) It is possible to provide a sickle-engagement strike device in which the degree of sickling applied to the strike is still good even if the door frame is somewhat distorted.
(2) Even if the parallelogram-like distortion of the door frame occurs, the strike main body can still be used satisfactorily as it is by re-adjusting the vertical fixing position of the auxiliary strike with respect to the trolley.
(3) Adjustment of the auxiliary strike with respect to the strike body or troyoke can be easily performed with a rational configuration.
(4) The end face U-shaped frame-shaped latching portion 17 for the sickle piece of the auxiliary strike B has left and right opposing side walls 17a and 17a protruding from the front portions of the left and right vertical side walls 16 and 16, and these opposing side walls. Since it has the vertical wall 17b arranged in a crossing manner, and the width dimension W of the opposing side walls 17a, 17a is set to be not less than 2 to 5 times the thickness of the sickle piece 5, for example, the door frame Even if the strike main body A is laterally displaced in the width direction of the sliding door in response to the distortion, the distal end portion of the sickle piece 5 is satisfactorily engaged with the frame-shaped latching portion 17.
