Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a closed locking device that can be detachably and conveniently attached to a double cabinet door, such as a base cabinet of a system kitchen, a vanity table, a TV cabinet, and a clog box.

[0002]

[Prior art]

 For example, in the base cabinet of the system kitchen, a storage box for kitchen knives is attached to the back of the double door, and there were children up to about 3 years old because kitchen knives were inserted and set here. It is very dangerous to open it too easily.

FIGS. 19 and 20 show a typical locking and locking device commercially available as a safety measure. This conventional locking / locking device comprises a rigid synthetic resin pedestal (1) (1) which is separately attached to the left and right pair of double doors (D) and (D) via an adhesive (not shown) from the front side. And a connecting band (2) made of a soft synthetic resin (elastomer) having a fixed length, which is detachably engaged between the left and right sides, and a center portion of each pedestal (1) (1). The dowels (3) and (3) protrude integrally from the front while the locking holes (4) and (4) for the dowels (3) and (3) are opened near both ends of the connecting band (2). Are distributed.

[0004] In use, first, both pedestals (1) and (1) are individually adhered to the surfaces of the double doors (D) and (D), respectively, and the dowels (3) of the two pedestals (1) and (1) are respectively bonded. (3) Continue to push the two locking holes (4) and (4) of the connecting band (2) from the front side and lock them, so that the double doors (D) and (D) are not easily opened. As a constraint.

[0005] Incidentally, (5) and (5) are a plurality of split grooves cut out at the opening edges of the locking holes (4) and (4), and (6) and (6) are the connecting bands (2). A pair of left and right knobs protruding from both ends. When the double doors (D) and (D) are unlocked and closed, the connecting band (2) is connected to the dowels (3) on the pedestals (1) and (1). ) (3) Used to pull out as if flipping up.

[0006]

[Problems to be solved by the invention]

 However, in such a configuration of the conventional product, the pedestals (1) and (1) are used as a pair of left and right sides, which are attached to the double doors (D) and (D) with an adhesive, and are separately scattered from the front side. The left and right pair of double doors (D) and (D) are not restrained at all from the back. Moreover, the connecting band (2) is a soft synthetic resin (elastomer) product.

Therefore, when the double doors (D) and (D) are forcibly opened to the front side with the handles (7) and (7), the connecting band (2) becomes substantially V-shaped in plan view. The pedestals (1) and (1), which have become unable to withstand the tensile force due to elongation and deformation, easily fall off so as to be peeled off from the surfaces of the double doors (D) and (D). As a result, disconnection of the connecting band (2) and detachment from the dowels (3) and (3) occur.

In particular, the pedestals (1) and (1) are bonded to the surfaces of the double-doors (D) and (D) in a state where the pedestals (1) and (1) are separately scattered and correspond to a pair of left and right doors. In use, it is not possible to position this on a line where the vertical bisector of its connecting band (2) correctly matches the abutment (Y) of the double doors (D) and (D). It is difficult to do so, and when a forcible opening operation force is received, the pedestal (1) located closer to the butting portion (Y) of the double doors (D) (D) is peeled off as soon as possible. That is, traces of the peeling of the adhesive are unsightly exposed on the surfaces of the double doors (D) and (D).

[0009] In short, a pair of left and right pedestals (1) and (1) which are separately attached to the surfaces of the double doors (D) and (D) depending on the adhesive force as in the conventional product, and the double doors (D) ( In the configuration including the connecting band (2) made of a soft synthetic resin that restricts D) only from the front side, a reliable locking / locking effect cannot be achieved yet. Furthermore, the adhesive strength of the pedestals (1) and (1) is apt to age, and the connecting band (2) stretches out and yields at an early stage, so that the durability as a closure locking tool is poor.

On the other hand, as shown in FIGS. 21 to 23, a hard synthetic resin rotating arm (8) is used in place of the connecting band (2), and its base end is connected to one pedestal ( 1a), is rotatably pivotally attached to a dowel (3a) projecting integrally from the front, and a hook (9), which is also cut out at the tip of the rotating arm (8), is connected to the other arm. There is also known a locking / unlocking device configured to be detachably engaged with a dowel (3b) projecting from the pedestal (1b) so as to face and integrally protrude.

Reference numeral (10) denotes an elastically deformable lock lever pivotally attached to the rotating arm (8) from the rear side. Unless the lever is pushed, the hook (8) of the rotating arm (8) is used. 9) cannot be released from the locked state with the dowel (3b).

[0012] However, even in the configuration of such a conventional product, the pair of left and right pedestals (1a) and (1b) are formed on the surfaces of the double doors (D) and (D) by the adhesive, respectively, so as to be in a different scattered distribution state. Since it is used for mounting, it is still easy to fall off from the double doors (D) and (D), and the rotating lever (8) or The lock lever (10) is broken instantaneously, and there is even a danger of the fragments being scattered.

[0013]

[Means for Solving the Problems]

 The present invention intends to drastically solve such problems, and therefore, as a locking device for a double door, a fixed frame having a fixed length that can be straddled between the left and right sides of the double door. And a movable board,

The fixed frame is formed into a substantially inverted L-shape in a side view from a horizontal plate surface capable of engaging and fitting to the upper surface of the double door and a rear plate surface capable of engaging and fitting to the back surface of the double door. A screw hole is formed from the middle part of the horizontal plate surface to the center of the front plate surface hanging down parallel to the rear plate surface,

The movable plate is provided with a rear wall surface facing at least a rear plate surface of the fixed frame and capable of being pressed and fitted to the surface of the double door, and a front plate surface receiving recess of the fixed frame at an intermediate portion of the rear wall surface. In the front plate surface receiving recess, a pair of front and rear fool holes corresponding to the screw holes on the fixed frame side are distributed in the opening, and

When the operation screw tube is rotated by screwing a male screw portion of the operation screw tube inserted into and penetrated into the fool hole from the front of the movable plate with a screw hole on the fixed frame side, Assemble so that the movable plate can move forward and backward toward the fixed frame,

[0017] Of the movable plate and the fixed frame that are fitted in a falling state that straddle the left and right doors between the left and right doors, the movable plate is advanced to the fixed frame by rotating the operation screw tube, and It is characterized in that it is set so that the double door is sandwiched and fixed by the moving platen and the fixed frame from the front and back.

[0018]

[Embodiment of the invention]

 1 to 9 show a basic embodiment of the closing / locking device of the present invention, wherein (A) is a double door type double door (D) (D). This is a fixed frame with a fixed length (W1) (for example, about 100 mm) that can be straddled between the left and right sides of each other. It is bent from a relatively thin and rigid metal plate into an almost inverted L-shape when viewed from the side. I have.

The horizontal plate surface (11) of the fixed frame (A) has a depth dimension (for example, about 25 mm) at least equal to the thickness (T) of the double doors (D) and (D), and the double doors (D) (D) so that the rear plate surface (12), which also hangs continuously from the horizontal plate surface (11), can be engaged with the rear surfaces of the double doors (D) and (D) in a fitted state, respectively. It is.

In this case, in the illustrated example, the relief groove (13) of the packing (not shown) projecting from the back surface of the double doors (D) and (D) is fitted to the rear plate surface (12) of the fixed frame (A). However, the cross-sectional shape of the plate surface (12) can be appropriately formed in order to fit the back surface of the double doors (D) and (D). Although not shown, an elastic lining may be integrated with the front surface of the rear plate surface (12) or the lower surface of the horizontal plate surface (11).

In any case, the intermediate portion of the horizontal plate surface (11) in the fixed frame (A) is in an extended state projecting forward from the thickness (T) of the double doors (D) and (D). A front plate surface (14) parallel to the rear plate surface (12) hangs continuously from the tip. (15) is a burring screw hole at the center of the front plate surface (14), and is assembled in a screwed state with an operation screw tube described later.

On the other hand, (B) is a movable plate having a fixed length (W2) which is equal to or slightly shorter than the fixed frame (A), and faces the rear plate surface (12) of the fixed frame (A). The flat rear wall (16) fits in a pressed state onto the surfaces of the double doors (D) and (D) in a pressed state, and together with the rear plate surface (12) of the fixed frame (A), the double door (16). D) (D) can be sandwiched. In order to fit the rear wall (16) of the movable plate (B) to the surface of the double doors (D) and (D), a horizontal groove (17) as shown in the figure is cut out or elastic lining is used here. (Not shown) may be integrated with the backing.

In particular, an intermediate portion of the movable platen (B) corresponding to the front plate surface (14) of the fixed frame (A) is depressed as a front plate surface receiving recess (18) of the fixed frame (A). Have been. Here, the front plate surface receiving recess (18) is opened in a square shape in plan view, and the opposing parallel inner wall surfaces are relative to the front plate surface (14) in the fixed frame (A). It functions as a guide rail, and when the operation screw pipe described later is rotated, the movable platen (B) moves only linearly with respect to the fixed frame (A) and does not rotate relatively. I have.

In the illustrated example, the movable platen (B) is formed into a flat rectangular cylindrical shape on both the upper and lower surfaces extending a fixed length (W2) from a hard synthetic resin. As long as the front plate surface receiving recess (18) is provided, the rear wall surface (16) of the movable plate (B) can be formed into a plate shape similar to the rear plate surface (12) of the fixed frame (A), The movable plate (B) itself may be plastically worked from a metal plate.

(19) is a front wall surface which forms a convex curved surface of the movable board (B), and the front wall surface (19) and the flat rear wall surface (16) are located at the center of the front plate surface receiving recess (18). A pair of stupid holes (20) and (21) facing the screw holes (15) on the fixed frame (A) side are formed in the positions facing the fixing frame (A). The male screw portion (22) of the operating screw tube (C) that has been penetrated is screwed and fastened to the screw hole (15) on the fixed frame (A) side.

That is, one set of the fixed frame (A) and the movable platen (B) is assembled via an operation screw pipe (C) having a fixed length (L) (for example, about 35 mm). The operation screw pipe (C) is formed as a hollow article from a hard synthetic resin. (23) is a retaining flange protruding in a tapered conical shape from the front end portion, and (24) is a split groove for contracting the diameter similarly cut out at the front end portion.

Therefore, the operation screw pipe (C) is opened from the large-diameter hole (20) opening on the front wall surface (19) of the movable platen (B) to the small-diameter air hole opening on the rear wall surface (16). When it is inserted into the hole (21), the retaining flange (23) at the tip that has contracted and deformed during the forcible passage through the rear fool hole (21) can be self-removed by the restoring and expanding force after the passage. It will be locked to the rear wall surface (16) of the moving platen (B), and there is no risk of slipping out. (25) is a concave stepped surface cut out at the center of the rear wall surface (16) of the movable board (B), and the retaining flange (23) of the operation screw pipe (C) is flattened on the rear wall surface (16). ) So that it does not overhang.

Reference numeral (26) denotes a rotary knob which forms a large head of the operation screw tube (C). When the rotary knob is rotated from the front of the movable plate (B), the movable plate is moved. (B) moves forward and backward with respect to the fixed frame (A). For this reason, the locking device of the present invention can be used by being sandwiched between the double doors (D) and (D), and can be conveniently removed.

[0029] Reference numeral (27) denotes a rotation guide arrow provided to the rotation operation knob (26). The moving direction in which the movable platen (B) approaches the fixed frame (A) (tightening of the operation screw tube). Direction). (28) is a concave stepped surface which is depressed at the center of the front wall surface (19) of the movable board (B), and the turning operation knob (26) of the operation screw tube (C) is excessively stretched forward. Prevent it from being issued.

Next, FIGS. 10 to 13 show a modified embodiment of the closing and locking device according to the present invention. As is clear from this, a hard synthetic resin decorative cover (E) is prepared, and the movable cover (E) is attached to the movable plate (B) and the fixed frame (A) from the front so that it can be freely inserted and removed. The front plate surface receiving recess (18), which is exposed at the center of the board (B), may be covered to enhance the decorative effect of the closing and locking tool. (29) is a cutout window cut out at the center of the front wall surface (30) of the decorative cover (E), and escapes the rotary knob (26) of the operation screw tube (C).

Since the other configurations in the modified embodiment of FIGS. 10 to 13 are substantially the same as those of the above-described basic embodiment, only the corresponding reference numerals to FIGS. Although the detailed description is omitted, in any case, the movable plate (B) and the separate decorative cover (E) may be colored in harmony with the double doors (D) and (D). it can.

FIGS. 14 to 18 show examples of use of the present invention applied to double doors (D) and (D) of a double door of a kitchen cabinet. To explain, since the fixed frame (A) and the movable platen (B) are in a previously assembled state via the operation screw pipe (C), the operation knob (C) of the operation screw pipe (C) is operated. 26), the movable plate (B) is rotated forward in the direction of loosening opposite to the rotation guide arrow (27), and the movable plate (B) is retracted forward away from the fixed frame (A). 14. Fit it to either one of the left and right sides of the double doors (D) and (D) that were previously opened as shown in FIG.

Then, the double doors (D) and (D) are closed so as to be in a straight line in a plan view, and the locking tool is locked by the double doors (D) and (D) as shown by an arrow (X) in FIG. By sliding the door toward the other side, the double doors (D) and (D) are maintained in a crossing state straddling between the left and right sides as shown in FIG.

Then, since the double doors (D) and (D) are in a state of being restrained by the movable board (B) from the front side and also by the fixed frame (A) from the back side, respectively, the operation screw pipe ( The movable plate (B) approaches the fixed frame (A) as shown in FIGS. 16 to 18 by rotating the operation knob (26) in the direction of tightening the rotation guide arrow (27). It moves forward and backward (Z), and is strongly pinched and fixed to the double doors (D) and (D).

A pair of left and right doors (D) and (D) arranged in parallel form a movable plate (B) having a fixed length (W2) and (W1) and a fixed frame (A) straddling the abutting portion (Y). In other words, as a result, the closing and locking tool is not likely to fall out of the double doors (D) and (D) as a result of being fixed in a pinching manner from both sides. There is no danger of opening.

Therefore, even when the operation screw pipe (C) is not located on the vertical center line which correctly matches the butted portion (Y) of the provisional double doors (D) and (D), there is no problem at all. It is possible to maintain a completely closed and locked state.

Conversely, when the double doors (D) and (D) can be opened, the movable screw pipe (C) is rotated from the closed and locked state shown in FIGS. The board (B) is retracted forward away from the fixed frame (A) to release the clamping force on the double doors (D) and (D), and then closed and locked as shown in FIGS. The tool can be slid back, and it can be further removed from one of the double doors (D) and (D) and stored.
