Description

[Detailed Description of the Invention] The present invention relates to an opening/closing device for doors of furniture, buildings, etc., and particularly relates to a general-purpose door mounting device that can easily adjust the inclination and entrance/exit of the door.

Conventionally, a pedestal 20 is fixed to a mounting wall as shown in FIG.
The door mounting member 21 is fixed to the center part of the door with a screw 22, and the tip of the adjustment screw 23 screwed into the free end of the door mounting member 21 is pressed against the top surface of the base 20, and the adjustment screw 23 is turned to close the door. Slightly move the free end of the mounting member 21 to the left and right to attach the door mounting member 3.
A door 25 is pivotally attached to the tip of the door 1 via a four-bar link 24.
A door opening/closing device that adjusts the inclination and entrance/exit of the door is common.

This device has the inconvenience that the inclination of the door cannot be adjusted simply by turning the adjustment screw 23, but the screw 22 must also be turned.

Adjustment of the inclination of the door 25 is generally within 5 degrees and usually requires fine adjustment, so the screw 22 and adjustment screw 23 are used.
Doors in which the inclination and entrance/exit cannot be adjusted without turning the door have the disadvantage that only a highly skilled person can use them.

In addition, even if there is a device that adjusts the inclination of the door 25 using a single adjustment screw, it has a complicated structure and is difficult to manufacture and assemble, and it cannot be installed on different types of pedestals, resulting in a lack of versatility. .

The present invention eliminates the above-mentioned drawbacks, and has an elastic adjustment plate pivoted on the upper surface of one end of the pedestal, and the other end of the free adjustment plate is connected to an adjustment screw screwed onto the pedestal. Then, turn the adjustment screw clockwise or counterclockwise to move the free end of the adjustment plate toward or away from the pedestal, fix the door mounting member above the top surface of the adjustment plate, and then move the adjustment plate 4 toward the pedestal. At the same time as approaching and separating, the inclination of the door attached to the tip of the door mounting member with a four-bar link etc. is adjusted, compared to a case where the door mounting member itself is adjusted without adjusting. The inclination of the door can be adjusted by turning only one adjustment screw, making it easy and quick to adjust the door. It is also easy to manufacture and assemble, especially when attached to several types of pedestals. It is highly versatile because it can be used to

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

Although FIG. 2 is a sectional view of the present invention seen from the plane, for convenience of explanation, this will be explained as seen from the front.

Reference numeral 1 denotes a mounting wall for the door 7, 2 a pedestal made of a die-cast product, a plastic product, etc., 4 an adjustment plate placed on the top surface of the pedestal 2, and a hole 2a made in one end of the pedestal 2.
The pedestal 2 and the adjustment plate 4 are pivoted by inserting the rivet 3 through a hole 4a made in the upper extension plate 4g connected to one end of the adjustment plate 4, that is, one end of the upper plate 4f.

An inclined relief surface 2b is formed on the upper surface of one end of the pedestal 2 where the hole 2a is made so that the free end of the adjustment plate 4 can move up and down without any hindrance.

The other end of the adjustment plate 4 is bent in the shape of a square so as to be spaced apart from the upper surface of the pedestal 2, and the side surface when viewed from the free end side is bent into a shape, and both sides 4b, 4b are bent into a shape. It operates using both side edges of the upper surface protrusion 2C of the pedestal 4 as a guide.

Reference numeral 5 denotes an adjustment screw screwed into a screw hole 2e made in the upper surface protrusion 2C of the pedestal 2, and its head 5,c and screw portion 5d
An elongated hole 4 made in the adjustment plate 4 in the groove 5a formed between the
Lock C.

Then, by inserting a screwdriver into the cross hole 5b drilled in the head of the adjustment screw 5 and rotating it clockwise or counterclockwise, the adjustment screw 5 is moved up and down, and the other end 6 of the adjustment plate 4 is moved forward and backward.
swings vertically around the rivet 3.

Since the adjustment plate 4 has elasticity, the groove 5a and the upper and lower peripheral edges of the elongated hole 4C of the adjustment plate 4 have good chamfering, and the movement of the adjustment screw 5 can be accurately transmitted to the adjustment plate 4.

2 d and 2 d are wood screws 11a and 1l drilled in the pedestal 2
This is the mounting hole b, and the wood screws lla and llb are attached to the mounting wall 1.
Attach to the top.

4d is a hole drilled in the adjustment plate 4 for inserting a screwdriver for the wood screw 11a.

Reference numeral 10 denotes a door mounting member screwed onto the adjustment plate with head screws 9, which is bent into a single shape when viewed from the side, and has a wood screw turning driver insertion hole 10 at the base of the top plate 10d.
The top plate 1 is provided with a hole a and is placed above the adjustment screw 5.
A turning driver insertion hole 10b for the adjustment screw 5 is provided at 0d.

The screwdriver insertion hole 10a is shaped like a tadpole, and the screw 9 screwed onto the adjustment plate 4 is inserted into the tail portion of the screwdriver insertion hole 10a, and the head of the screw 9 is locked onto the upper surface of the door mounting member 10.

The base end 10C of the door mounting member 10 is engaged with a notch 4e formed on the upper surface of the base end of the adjustment plate 4, and is engaged with the adjustment plate 4 within the tail portion of the screwdriver insertion hole 10a. After moving the door mounting member 10 in the left and right direction,
Tightly screw screw 9 into adjustment plate 4.
and the door mounting member 10 are fixed together.

7 is a four-bar link 8 a at the free end of the door mounting member 10 ,
8b is the installation door.

In fact, the adjustment range for the inclination of the door is within 5 or 6 mm.

As mentioned above, in this invention, the door mounting member is fixed to the adjustment plate, so to adjust the inclination of the door, simply insert the screwdriver through the screwdriver insertion hole in the door mounting member and turn the adjustment screw. Adjust with . With the rate, the door mounting member can be moved by slightly moving the free end, that is, the mounting point of the door, in the vertical direction around the rivet, so there is no looseness between the pedestal and the adjustment plate, and the adjustment plate can be machined. Since there are no screws, adjustment work can be performed very easily, and the adjustment plate can be moved toward or away from the base together with the adjustment screw.

In addition, since the present invention only requires a single screw to attach the door mounting member to the adjustment plate, the adjustment plate and door mounting member are highly compatible, and can be conveniently set on a conventional base, resulting in a simple structure. Therefore, it is easy to operate and can be provided at a low price.
