  According to such a conventional technique, the raised and dropped hardware is exposed on the surface of the door or the like, so there is a disadvantage that the appearance and appearance are not necessarily good. If this is to be concealed, a special storage space must be provided. In addition, there is a problem that it is cumbersome and extremely inconvenient when performing maintenance or replacement.

  Accordingly, in view of the problems of the prior art, an object of the present invention is to easily embed and install in a door or the like by combining a drive unit, a mounting frame, and a surface frame, and can be easily attached and detached. To provide raised and dropped hardware.

  In order to achieve this object, the configuration of the present invention includes a drive unit that houses an operation plate for connecting a latch rod in a reciprocating manner in a case body, and a mounting frame that houses the drive unit by projecting the latch rod to the outside. And a surface frame for screwing and fixing the drive unit to the mounting frame together with the guide frame, the operation plate is connected to the case body via a swinging link with a spring, and the mounting frame and the guide frame are The gist is that the movement path of the operation plate is regulated and the drive unit holds the operation plate at both the forward limit and the backward limit.

  The operation plate can be provided with an operation knob exposed at the opening of the surface frame.

  According to the configuration of the present invention, the drive unit stores the operation plate for connecting the latch rod in the case body so as to be reciprocally movable, and the mounting frame stores the drive unit by protruding the latch rod to the outside. Therefore, if the mounting frame is embedded and fixed in a door, the drive unit is stored in this mounting frame, and the drive unit is screwed and fixed together with the guide frame via the surface frame, the entire structure can be made into a door or the like. The guide frame and the drive unit can be easily taken out by removing the surface frame. Note that the latch rod connected to the operation plate protrudes outside the mounting frame, and fixes the door or the like by inserting the tip portion into a receiving member installed on the floor surface, the door frame, or the like. On the other hand, the operation plate can be held at a forward limit where the latch rod protrudes long to fix the door or the like, and can be held at a backward limit where the latch rod is fully retracted to release the door. However, the operating plate has a storage depth with respect to the case body via the mounting frame and the guide frame, and the movement path is regulated, and the reciprocating manual operation is smoothly performed from one of the forward limit and the reverse limit to the other. can do.

  The operation plate can be connected to the case body via a rocking link with a spring to realize a good snap feeling. The swing link regulates the movement stroke of the operation plate, and the spring properly energizes the swing link, so that the operation plate can be operated at the intermediate point where the operation plate moves from one of the forward limit and the reverse limit to the other. This is because the peak of power can be made.

  The operation plate can be manually operated from one of the forward limit and the backward limit via the operation knob by attaching an operation knob exposed at the opening of the surface frame. The operation knob may be a connection point that connects one end of the swing link to the operation plate.

  The mounting frame 21 accommodates the drive unit 10 and can be assembled together with the guide frame 22 and the surface frame 23 through the machine screws 24, 24. That is, the mounting frame 21 is formed by bending the plate material, so that the support walls 21b and 21b are erected on the short side of the storage space 21a for the drive unit 10, and the support pieces 21c that support the flanges 13a and 13a of the case body 13 are supported. 21c are formed inwardly at the upper edge of each support wall 21b, and each support piece 21c is formed with a screw hole 21d that fits the machine screw 24. In addition, a round hole 21e through which the latch rod 11 of the drive unit 10 passes is formed in one support wall 21b. Furthermore, the mounting frame 21 is combined with a mounting material 21g that forms mounting pieces 21f, 21f orthogonal to each other.

  Such raised and dropped hardware can be embedded and installed in the lower corner of the door 50 on the side opposite to the hinge (FIGS. 4 and 5). The raised and lowered hardware projects the latch rod 11 downward from the lower end of the door 50, inserts the front end of the latch rod 11 into the receiving member 25 embedded in the floor F, and engages the door 50 temporarily. Can be fixed.

  The door 50 is formed by attaching surface materials 52 and 52 to both surfaces of the core material 51 of the paper honeycomb. Structural members 53, 53... Are arranged on the four circumferences of the core member 51, and a collar member 54 is attached to each side end surface of the door 50. Further, at the lower end of the door 50, sealing materials 55 a and 55 a are suspended up to the vicinity of the floor surface F via lower covering materials 55 and 55.

  As for the raising and dropping hardware, the mounting pieces 21f and 21f of the mounting frame 21 are screwed to the vertical and horizontal structural members 53 and 53 in the door 50, the drive unit 10 is stored in the mounting frame 21, and the guide frame 22 and the drive unit 10 Together with the case body 13, the surface frame 23 is screwed and fixed to the mounting frame 21 via small screws 24, 24. The latch rod 11 of the drive unit 10 protrudes downward from the mounting frame 21 and penetrates the hole 53a of the lower structural member 53 from above to below.

  The latch rod 11 can be driven up and down via the operation knob 16 exposed in the opening 23a of the surface frame 23 (the solid lines and the two-dot chain lines in FIGS. 4 and 5). That is, the operation knob 16 and the latch rod 11 are integrally assembled via the operation plate 12, and the operation plate 12 can be stably reciprocated in the long side direction of the case body 13. The latch rod 11 side of the operation plate 12 is positioned by the latch rod 11 passing through the round hole 21e of the mounting frame 21 (FIG. 1), and the other end side is the opposite support wall 21b facing the round hole 21e. Between the upper support pieces 21c and 21c, the upper end edge of the support wall 21b and the lower surface of the guide tongue piece 22c of the guide frame 22 are positioned and positioned. This is because the reciprocating path is regulated via the guide frame 22.

  The lower limit of the operation plate 12 and the latch rod 11, that is, the forward limit of both, is regulated by the bending portion 12 a of the operation plate 12 connecting the latch rod 11 coming into contact with one support wall 21 b of the mounting frame 21 (see FIG. 5), the ascending limit of the operation plate 12 and the latch rod 11, that is, the retreating limit of both is regulated by the bent portion of the reinforcing plate 16a on the back side of the operation plate 12 coming into contact with the other support wall 21b. (The two-dot chain line in the figure). The operation plate 12 and the latch rod 11 are held via the swing links 14 and 14 and the spring 15 in both the forward limit and the backward limit. The operation force when driving the operation plate 12 via the operation knob 16 is from either one of the forward limit (two-dot chain line in FIG. 2) and the reverse limit (solid line in FIG. Up to the point (the one-dot chain line in the figure), it increases uniformly as the amount of deformation of the spring 15 increases, decreases uniformly by exceeding the intermediate point, and substantially disappears at the forward limit or reverse limit. Because.

  The procedure for incorporating the raised and lowered hardware into the door 50 is, for example, according to steps (1) to (8) in FIGS. However, in the following description, steps (1) to (8) in FIGS. 6 and 7 are simply written as (1), (2)... (8).

(1) Subsequently, the drive unit 10 is housed in the mounting frame 21 ((1) to (3)). At this time, the drive unit 10 removes the latch rod 11 from the operation plate 12, and the operation plate 12 is retreated in the case body 13 to the retreat limit. Therefore, the rear end portion of the operation plate 12 protruding from the case body 13 is inserted into the back side of the surface material 52 of the door 50 ((1), (2)), and the drive unit 10 is stored in the mounting frame 21. (3)

  Subsequently, the guide frame 22 is set on the drive unit 10 ((4), (5)), and the surface frame 23 is screwed and fixed from above the guide frame 22 via the machine screws 24, 24. 6). Thereafter, the latch rod 11 is connected to the operation plate 12 through the hole 53a of the structural member 53 of the door 50 ((7), (8)). The latch rod 11 may be connected by screwing the male screw portion 11a into the nut 12b on the operation plate 12 side.

  The door 50 is assembled to a hinge of a door frame (not shown) after the raised metal piece is assembled as described above. However, the receiving member 25 corresponding to the latch rod 11 is embedded in advance at a predetermined position on the floor surface F. In addition, what is necessary is just to perform step (1)-(8) of FIG. 6, FIG. 7 in reverse order, after removing the door 50 from a door frame, when removing the raising and dropping metal fitting in the door 50. FIG.

  In the above description, instead of using the spring 15 and the swing links 14, 14, the operation plate 12 and the latch rod 11, for example, by engaging / disengaging a simple external locking member with the operation knob 16, You may hold | maintain in both the forward limit and backward limit.

  The raised and lowered hardware according to the present invention can be used by causing the latch rod 11 to protrude upward or laterally from the door 50 and installing the corresponding receiving member 25 on the door frame. It is also possible to fix the raised and lowered hardware on the door frame side and provide the receiving member 25 on the door 50 side. Further, the raised and dropped hardware can be suitably applied to other arbitrary windows, doors, shoji screens, etc. instead of the door 50.
