Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a movable strike (hereinafter simply referred to as a movable strike) of a gremon lock, and in particular, it is possible to adjust the engagement position with the locking rod of the gremon lock and to keep the adjustment amount stable over a long period of time. Regarding movable strikes.
[0002]
[Prior art]
Gremon locks are provided with a locking rod along the free edge of the door, the locking rod is moved up and down by the handle operation when the door is closed, and the tip is opened to the upper side and / or lower side of the door frame. It is a locking device that engages in the rod hole and fixes the door.
[0003]
Normally, the cross-sectional shape of the locking rod is, for example, circular, and the corresponding rod hole opened in the door frame is a circular hole that is slightly larger than the outer diameter of the locking rod, and its position is usually It is fixed and cannot be adjusted.
[0004]
[Problems to be solved by the invention]
The above-described strike of the conventional Gremon lock (receiving member of the locking rod, in this case, the member having the opening of the rod hole) is simple in structure and can lock the door without looseness. For example, when the door surface is distorted and the positions of the locking rod and the rod hole are slightly out of order, there is a disadvantage that the locking rod is not smoothly inserted into the strike when the door is closed.
[0005]
On the other hand, the conventionally proposed dead bolt or latch bolt strike, and the movable strike that can adjust the position of engagement with these bolts normally uses frictional engagement of members. Although the adjustment amount cannot be kept stable for a long period of time and readjustment must be repeated, the readjustment is difficult, for example, on the upper side of the door frame.
[0006]
Accordingly, an object of the present invention is to provide a movable strike that can adjust the engagement position with the locking rod and can keep the adjustment amount stable over a long period of time.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a horizontal plate-like body mounted on the upper side or the lower side of a door frame, and opens a strike hole through which the tip of a locking rod of a Gremon lock is inserted in the center. In addition, the strike plate is sandwiched between the strike holes in the prospective direction, and at least a pair of set screw holes are formed around the strike plate, and a roller disposed on the back side of the strike plate and extending in the prospective direction is rolled. It is a frame that can be carried, and at least a pair of sliding contact pieces facing each other in the prospective direction is integrally connected to the side to be joined to the back surface of the strike plate, and extends to the respective sliding contact pieces in the direction of finding. Along with opening the elongated holes, the roller base with the interval between these elongated holes set to be the same as that of the pair of set screw holes of the strike plate, and the sliding plate is sandwiched with the strike plate And a fixing plate having a female screw hole that is screwed with a set screw, a first serration formed on the sliding contact piece and extending in the direction of finding, and formed on the fixing plate and extending in the direction of finding. A second serration that is engageable with the first serration and is stepped by changing the engagement of the first and second serrations to position the roller that intersects and engages the locking rod of the Gremon lock It can be adjusted to
[0008]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a strike plate, and the strike plate 1 is a plate-like body having a rectangular shape as a whole, with mounting screw holes 2 and 2 at its four corners, and a Gremon tablet not shown at the center. The strike hole 3 through which the tip of the locking rod is inserted is opened.
[0009]
In the vicinity of the strike hole 3, at least a pair of set screw holes 4 and 4 are opened so as to sandwich the strike hole 3 in the prospective direction, that is, the width direction of the door.
[0010]
In the illustrated embodiment, both the strike mounting screw (not shown) and the set screw 5 are countersunk screws.
[0011]
A roller base 6 is disposed on the back side of the strike plate 1 (lower side in FIG. 1). The roller base 6 in the illustrated embodiment is a plate material that is bent so that the projected shape with respect to the strike plate 1 becomes a U-shape, and extends in the prospective direction so as to increase the rigidity by connecting the open leg portions. A roller 7 is supported so as to be able to roll.
[0012]
In addition, a pair of edge portions facing each other in the prospective direction among the end edges of the roller base 6 on the side to be joined with the strike plate 1 are bent outward, and the sliding contact pieces 8 and 8 each having a rectangular overall shape are integrated. Is formed.
[0013]
Each sliding contact piece 8 has a long hole 9 extending in the direction of finding, that is, the thickness direction of the door. The distance between the long holes 9 and 9 is the distance between the set screw holes 4 and 4. Is set to be the same.
[0014]
Moreover, the 1st serration 11 extended in a prospective direction similarly to the long hole 9 is formed in the outer edge of each sliding contact piece 8. As shown in FIG.
[0015]
Furthermore, a rectangular fixed plate 12 having an elongated overall shape is disposed on the side opposite to the strike plate 1 with respect to the sliding contact piece 8, in other words, on the lower side of the sliding contact piece 8 in FIG.
[0016]
A female screw hole 13 that is screwed into the set screw 5 is formed at the center of the fixing plate 12.
[0017]
In addition, the outer edge of each fixed plate 12, that is, the side end edge of the fixed plate far from the roller base 6 is plastically processed so as to protrude toward the strike plate 1 by, for example, press working. A second serration 14 that can mesh with the first serration 11 is formed on the side facing the first serration 11.
[0018]
In FIG. 1, reference numeral 15 denotes a restricting piece projecting from the inner edge of each fixed plate 12. This restricting piece 15 is a roller base 6 in a state where the movable strike according to the present invention is assembled as will be described later. The rotation of the fixed plate 12 is regulated by sliding contact with the outer surface of the plate, but this is not an essential component of the present invention.
[0019]
The strike plate 1, the roller base 6, and the fixing plate 12 configured as described above are inserted into the strike plate 1 and the long hole 9 of the sliding contact piece at the position shown in FIG. And a set screw 5 that is screwed together.
[0020]
At this time, since the first serration 11 and the second serration 14 are in the same elevation, they mesh with each other.
[0021]
Then, as shown in FIG. 2, for example, with a box-shaped trolley 16 having an opening on one surface being fitted, it is attached to the upper side of the door frame by mounting screws 17, 17, for example. The presence of this troy is not an essential component of the present invention.
[0022]
As shown in FIG. 2, in the state where the movable strike according to the present invention is mounted on the door frame, when the Gremmon lock is operated in the locking direction, the locking rod 18 rises and engages with the roller 7 so as to intersect. It is locked to.
[0023]
At this time, even if the position of the locking rod 18 in the finding direction is slightly different, the position of the locking rod 18 is automatically corrected by the wedge action generated between the cross-sectional shape of the roller 7 and the locking rod. For example, when the door is tightened while the packing material is being compressed, such as an airtight door, the roller 7 automatically performs the compression.
[0024]
The reaction force received by the roller 7 from the locking rod 18 is carried on the strike plate 1 via the roller base 6, the sliding contact piece 8, the meshing engagement of the first and second serrations 11, 14, and the set screw 5. Is done.
[0025]
In order to adjust the position of the roller 7 in the direction of finding, the set screw 5 is first loosened, the first and second serrations 11 and 14 are disengaged, and the roller base 6 is moved in the direction of finding. Then, after adjusting the serration step by step, the set screw 5 is tightened again to fix the new serration mesh.
[0026]
The position of the roller base 6 can be adjusted without removing the strike plate from the door frame by inserting a tool or finger into the strike hole 2 of the strike plate.
[0027]
【The invention's effect】
As is apparent from the above description, in the present invention, the roller base is mounted on the strike plate through the meshing of the first and second serrations, so that the position of the roller base can be adjusted and, of course, the serration teeth Since the position of the roller base is fixed by the shape engagement, once the position is adjusted, the adjustment amount can be maintained over a long period of time.
