Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a door to a sink or the like, and its purpose is to enable the door to be attached easily and reliably.

Generally, the door of a sink or the like is attached to a cabinet via a hinge, but the work of attaching the door and the hinge is extremely troublesome.

Specifically, the door is screwed to the movable hinge metal fitting of the hinge that is attached to the cabinet, but there are many screws to be screwed, and there are generally three screws, so it takes time and effort to screw the screws. Furthermore, since the hinge was necessarily installed at the end of the door close to the cabinet, the cabinet got in the way of the screw-fastening work, making the work difficult.

Therefore, it may be possible to improve work efficiency by setting the screws in one place, but if the screws were only in one place, the movable hinge metal fitting would rotate relative to the door, and it would be necessary to use the screws in two places. Even so, there was a problem in that the door would rattle if one of the screws came loose, making it impossible to expect reliable installation.

Therefore, as a solution to this problem, as shown in Fig. 4, a movable hinge opening with a locking groove formed by knurling on at least the back surface is pivotally attached to a fixed hinge, and a locking groove formed by knurling is formed on the entire surface. A plate-shaped fixing member 2 is fixed with a piston on the upper end surface of the door, and the movable hinge opening and the fixing member 2 are fixed with screws in an overlapping state, and a locking groove H,
A structure is conceivable in which the fixation is ensured by the engagement of comrades.

However, since the locking groove of the fixing member 2 is formed over the entire surface, the strength of the fixing member 2 itself becomes weak, and especially when used after knurling to form the locking groove, A bowing phenomenon as shown by the two-dot chain line occurs, and a problem arises in that the movable hinge fitting opening cannot be sufficiently fixed.

In addition, if the piston that attaches the fixing member 2 to the door is tightened diagonally when screwing, the head of the piston will protrude considerably from the surface of the fixing member 2, and this will also cause the fixation of the movable hinge metal opening. The problem arises that it doesn't work.

The present invention solves the above-mentioned problems, and embodiments thereof will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a cabinet, 2 is a door attached to this cabinet 1, 3 and 4 are hinges that rotatably connect these two, and the upper hinge 3 is attached to the cabinet 1 with a screw 5. It consists of a fixed hinge metal fitting 3a and a movable hinge metal fitting 7 pivotally connected to the fixed hinge metal fitting 3a with a pin 6.

The shape of this movable hinge metal fitting 7 is approximately concave,
A locking groove 7b is formed on at least the back surface of the concave portion 7a by a low-reflection I process.

Further, the recessed portion 7a has an insertion hole 9 for the thickness adjustment screw 8.
A long hole 10 connected to the insertion hole 9 is provided.

11 is a plate-shaped fixing member attached to the upper end surface of the door 2 with a fastener 11a such as a screw, and has a width narrower than the plate thickness of the door 2, and the central part in the length direction is raised,
A locking groove 12a into which the locking groove 7b locks is formed on the upper surface of this raised portion 12 by knurling.

A tapped hole is formed in the raised portion 12, and a thickness adjusting screw 8 is screwed into this tapped hole.

The lower hinge 4 is composed of a fixed hinge 4a attached to the lower end of the cabinet 1 and a fixed hinge metal fitting 13 attached to the lower end surface of the door 2. A certain pin 14 is fixed hinge 4a
It is inserted into a pivot hole 15 provided in the.

Next, to install the door 2, first insert the pin 14 of the fixed hinge metal fitting 13 into the pivot hole 15 provided in the lower fixed hinge 4a, and then insert the surface of the raised part 12 of the upper fixed member 11 into the movable hinge metal fitting 7. The door 2 is connected to the cabinet 1 so as to be openable and closable by contacting the back surface of the cabinet 1 and tightening the long hole 10 formed in the concave portion 7a of the movable hinge fitting 7 with the thickness adjustment screw 8.

Here, if the door 2 is tilted as shown by X and y in FIG. Since the fixing member 7 is provided with an insertion hole 9 through which the screw 8 can be inserted and removed, the door 2 can be removed from the movable hinge fitting 7 without removing the thickness adjusting screw 8.

Further, the fixing member 11 has a locking groove 12a formed in a part thereof, and does not have a bowed state as in the conventional case where the locking groove is formed by knurling or the like over the entire surface of the fixing member. Moreover, since the locking groove portion has a raised portion 12, if the fixing member 11 is fixed with the stopper 11a at both ends other than the raised portion 12, the stopper 11a, for example, a screw Even if the head of the screw protrudes a little, the head of the screw will not fit into the movable hinge fitting 7 because of the raised part 12.
The locking groove 12a and the locking groove 7b are securely locked together, and the fixed member 11 and the movable hinge fitting 7 are prevented from coming into contact with each other.
can be securely fixed.

As described above, according to the present invention, the inclination of the door can be corrected by simply loosening the thickness adjustment screw, and the movable hinge metal fitting has an insertion hole through which the thickness adjustment screw can be inserted and removed.
The door can be removed from the movable hinge fitting without removing the thickness adjustment screw, and since the fixing member has a locking groove in the center, it is not possible to create a locking groove on the entire surface of the fixing member like in the past. 1 - The occurrence of arching can be prevented compared to those formed by processing, etc., and since the locking groove part is a raised part, the fixing member can be fastened at both ends other than the raised part. If it is fixed, even if the head of a stopper, such as a screw, protrudes a little, the head of the screw will not come into contact with the movable hinge metal fitting because of the raised part, and the locking groove on the fixed member side will not engage with the movable hinge side. This provides various effects such as reliable engagement with the groove and secure fixation of the fixed member and the movable hinge fitting.
