Description

[Detailed Description of the Invention] The present invention relates to a door fixing device for a double door used for furniture such as a wardrobe or the like.

Traditionally, in double doors, one of the left and right doors (usually the left door) was fixed to the main body opening of a wardrobe, etc., and the other door was closed with various catchers. The structure for fixing the side door to the main body opening is to install rods that can move up and down on both the top and bottom of the free end of the iron door, and push these rods up or down with your fingertips to engage them with the holes provided on the main body side. However, once the fixed side door is opened, the rod must be operated one by one to fix it in the open position, making it troublesome to operate the door.

Therefore, the present invention aims to automatically fix the iron door when the door is closed, and its configuration is as follows.

The present invention comprises a fixture that is attached to the free end of the door, and a receiving fixture that is attached to the furniture body, which is made up of a base having a retaining hole and a series of contact pieces attached to the rear of the base. The mounting housing has a fixed rod outlet and a stopper on the mouth edge of the outlet, and the receiver engages with the retaining hole of the tool through the fixed rod outlet of the mounting housing. a fixing rod that is slidably provided in the vertical direction within the mounting casing so as to be detachable, and whose tip abuts against a stopper of the mounting casing in a state in which it is disengaged from the engagement hole and is held in the detached position; a spring that always applies a spring force to the fixing rod in a direction to engage the engagement hole, and applies a spring force to the fixing rod in a direction to abut the stopper when the fixing rod is separated from the retaining hole; A door fixing device for a double-hung door, comprising an operator for disengaging the locking rod from the engagement hole against the spring, and a pusher for releasing the fixing rod from the stopper by being pressed by the abutment piece when the door is closed. In order to prevent the fixing rod from protruding from the retaining hole when the fixing rod is secured to the mating hole, the base of the receiver is formed to have a thickness greater than the effective engagement length of the fixing rod, and Door fixing for a double door, characterized in that the surface of the base of the tool from the front end to the retaining hole is formed into an inclined surface such that the thickness of the iron part gradually increases toward the retaining hole. It is a device.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 indicates a fixture, and reference numeral 2 denotes a receiver corresponding to the fixture 1. This device normally uses both 1 and 1 on furniture, etc., at the free end of the fixed side door and on both sides above and below the center of the opening of the main body. It is constructed by attaching one set to each.

However, on both the upper and lower sides, the structure of fixture 1 and fixture 2 and the mounting structure for furniture etc. are exactly the same. Regarding the sides, illustration and explanation will be omitted assuming that the directions of both 1 and 2 are reversed up and down.

The fixture 1 includes an elongated mounting casing 3, a back plate 4 attached to the back opening of the casing 3, a fixing rod 5 provided inside the casing 3,
It also consists of a tension coil spring 6, etc.

A slot-shaped fixed rod lead-out lower is provided on the upper end surface of the mounting casing 3,
The rear mouth edge 8 of the lower outlet on the same plane is used as a stopper.

Further, a headed shaft-shaped presser 9 is attached to the upper end of the surface of the casing 3 so as to be movable back and forth while penetrating the surface wall of the casing.

10 is a long hole for leading out the operator provided in the center of the surface of the housing;
11°11 is a mounting hole.

The fixing rod 5 is formed by bending a long and thin plate into an H shape, and slides vertically with its lower half in sliding contact with the inner surface of the casing 3 to protrude or retract above the casing. ing.

Reference numeral 12 denotes a shaft-shaped operator protruding from the fixing rod 5, which projects outward through the elongated hole 10 of the housing 3.

The tension coil spring 6 is stretched between the lower end of the fixed rod 5 and the upper inner surface of the back plate 4, and is caused by the spring 6 to always project upwardly from the fixed rod 5, that is, upwardly from the housing. The spring force is applied.

Furthermore, since the spring 6 is stretched between the fixed rod 5 and the back plate 4, a rotational moment acts on the fixed rod 5 in a direction in which the lower end thereof faces the back plate 4.

Therefore, when the fixing rod 5 is retracted into the housing 3, the upper end surface of the intermediate portion comes into contact with the stopper 8 of the housing 3, so that the fixing rod 5 is held in the retracted position.

Then, the tip of the pusher 9 comes into contact with the upper end of the fixing rod 5, and as the pusher 9 is pushed from the outside, the upper end of the fixing rod comes off the stopper 8 and faces the lower fixing rod guide. .

Reference numeral 13 denotes an insertion hole for a mounting screw provided in the fixing rod 5, which is shaped like a slot and has a length equivalent to the slide stroke of the portion 5.

14. 14 is a screw insertion hole in the back plate 4.

This fixture 1 is attached, for example, to the upper end of the inner surface of the free end of a fixed side door (usually the left door) Dl of a double door of a wardrobe.

On the other hand, the receiver 2 is made up of a contact piece 16 that is vertically connected to the rear of a base 15, and has an engagement hole 17 in the center of the base 15 and mounting holes 18 and 18 on both sides thereof.

A portion 19 of the surface (lower surface) of the base 15 from the front end to the engagement hole 17 is formed into a front curved inclined surface, that is, an inclined surface whose thickness gradually increases toward the engagement hole 17.

This inclined surface 19 allows the interspace 5 to be automatically engaged with the engagement hole 17 even if the fixing rod 5 unexpectedly protrudes before the door is closed.

The thickness of the base 15 is such that when the fixing rod 5 engages with the retaining hole 17, the gap 5 does not pass through the engagement hole 17 and protrude upward. The length is longer than the effective engagement length.

Specifically, as shown in Fig. 5, in the closed door position,
From the protruding length l of the fixed rod 5 from the mounting casing 3, the casing 3
It is sufficient to form the thickness S of the base 15 to be equal to or larger than the length (effective engagement length) l' minus the gap m between the upper end surface and the lower surface of the base 15.

When the gap m is approximately zero, the protrusion length is l and the thickness is S.

In addition, the above effective engagement length l' is, of course, a sufficient engagement force (
The length should be such that the door fixing force can be obtained.

In this way, in order to compensate for the lack of retention depth due to only the fixing rod 5 and the base 15, as in the case where the base 15 is made into a thin plate, there is no need to perform hole drilling on the frame of the furniture body. There is no need to worry about it.

The bracket 2 is attached, for example, to the inner surface of the front end of the center of the upper wall of the main body A of the wardrobe, which corresponds to the fixture 1.

Next, the operation of this device will be explained.

A state in which the left door D1 is fixed in a closed position is shown in FIGS. 4 to 6.

At this time, the fixing rod 5 protrudes upward and the receiver engages the engagement hole 1 of the tool 2.
7, the left door D1 is firmly fixed in the closed position.

In this state, the right door D2 can be freely opened and closed, and the right door D2 is closed to the left door D1 by a catcher (not shown).

Furthermore, when it is desired to open the left door D1, the fixing rod 5 is removed from the engagement hole 17 by pushing down the operator 12 and retracted into the housing 3.

This releases the fixation of the left door D1 and allows it to be opened freely.

When the fixing rod 5 is retracted, its upper end surface abuts against the stopper 8 and is held in the retracted position.

However, when the left door D1 is closed from this state, the pusher 9
hits the contact piece 16 and is pushed, which causes the fixed rod 5 to
The upper end of is removed from the stopper 8.

Therefore, the fixing rod 5 protrudes upward due to the spring force of the spring 6 and automatically engages with the retaining hole 17, returning to the state shown in FIGS. 4 to 6.

In this way, this device is designed to automatically fix the iron door D1 when the door D1 is closed. Therefore, it is no longer necessary to perform the door fixing operation every time as in the past, and the operation is significantly simplified. Ru.

Furthermore, with the door D1 open, the fixing rod 5 may unexpectedly protrude due to vibration, impact, or the like.

In this device, even if the door D1 is closed without realizing it in such a case, the fixing rod 5 slides into contact with the inclined surface 19 of the receiver base 15 and is temporarily retracted, as shown in FIG. Since it automatically engages with the engagement hole 17, it is possible to obtain the same door fixed state as when the original closing operation is performed.

Therefore, without the trouble of manually retracting the fixing rod 5, there is no risk of the door being closed without being noticed and hitting the fixing rod 5 or the base 15, and the shock causing damage to the fixing rod 5, etc. do not have.

It should be noted that the shape of the fixing rod can be changed as appropriate other than in the above embodiments.

As described above, according to the present invention, the fixed side door of a double door can be automatically fixed, which greatly simplifies the operation.In addition, this fixed state is reliable, and the unfixing operation is also easy. , very convenient to use.

Furthermore, there is no need to perform any additional processing such as drilling holes on the furniture body, and the receiver can be used as is by simply attaching the fixtures and fixings.

Further, even if the fixing rod unexpectedly protrudes before the door is closed, the automatic fixing action of the door can be reliably maintained by engaging the fixing rod with the retaining hole without any problem.

Moreover, according to the present invention, the spring that applies the force of engagement to the retaining hole to the fixing rod also serves as a spring for pressing the fixing rod against the stopper, and the mounting casing itself also serves as the stopper. Because of this structure, the number of parts is kept to a minimum, the structure is simple, assembly is easy, and the cost can be kept low, so it has extremely high practical value.
