Description

[Detailed description of the invention] This invention relates to a plug-in hinge suitable for doors of electronic equipment cabinets, stands, furniture, etc., especially for double-sided doors that can be attached to the left and right sides.The purpose of this invention is to
The purpose is to easily make corrections when the above-mentioned doors are installed at different levels above and below.

As shown in FIG. 1, for example, there are doors 2,
When the left and right doors 2 and 2' are installed so that they can be opened and closed by inserting hinges 3, the left and right doors 2 and 2' are often installed at different levels.

As shown in FIG. 2, the conventional insertion hinge 3 has a pin 5 fixed to an insertion fitting 4 constituting the insertion hinge 3, and a receiver having a cylindrical shape into which the pin 5 is simply inserted into the fitting 6. Since the left and right doors 2, 2' are installed at different heights, the height can be adjusted by inserting a separate piece, such as a washer 8, into the pin 5. In other words, the left and right doors 2, 2' are corrected so that the upper and lower levels are not different.

However, using such a washer 8 means that it is necessary to prepare the washer 8 in advance, and that it is necessary to use several washers 8 depending on the degree of difference between the upper and lower levels, or to use washers of different thicknesses. This is extremely inconvenient as it is necessary to prepare a There was a drawback.

This invention was designed to eliminate such conventional drawbacks, and will be explained with reference to the embodiments shown in Figure 3 and below. Figure 3 is a front view of the insertion hinge of this invention, and Figure 4 is a front view of the insertion hinge of this invention. FIG. 5 is a perspective view of the main parts of one of the insertion fittings constituting the hinge, and one of the insertion fittings 11 constituting the insertion hinge 10 has a flat plate portion 12 and approximately one side edge thereof. A cylindrical part 13 is integrally formed in the half part, and this cylindrical part 13 has a slit 13a in the axial direction and a slit 13a along the slit 13a at predetermined intervals from one wall of the slit 13a in the axial direction. An engaging hook hole 13b is formed which is cut out in a substantially orthogonal direction.

On the other hand, a protrusion 15 is implanted at the proximal end of the pin 14 to be inserted into the cylindrical part 13 in a direction substantially perpendicular to the axial direction of the pin 14 . ) 13a and has a thickness that allows it to be engaged with the engagement hook hole 13b.

The cylindrical part 13 and the pin 1 inserted and attached thereto
4 is configured as described above, the protrusion 15 protruding from the proximal end of the pin 14 is connected to the sulin (13) of the cylindrical portion 13.
The pin 14 can be attached to the cylindrical portion 13 with a predetermined projecting length by passing through the pin 14 and engaging with predetermined engagement hook holes 13b formed at a plurality of locations at predetermined intervals.

On the other hand, the other receiving metal fitting 16 constituting the insertion hinge has a flat plate portion 17 and a cylindrical portion 18 having a bottom portion 18a formed integrally with the flat plate portion 17 at approximately half of one side edge thereof.

Note that 19 is a screw hole drilled in the flat plate portion 12 of the insertion fitting 11 and the flat plate portion 17 of the metal fitting 16.

Further, the bottom portion 18a is not limited to the one in which a disk-shaped member is fitted and fixed to the lower end of the cylindrical portion 18 as shown in the figure, but may be formed integrally with the cylindrical portion 18, in other words, the bottom portion 18a may be formed integrally with the cylindrical portion 18.
It may be any type of material that can be stopped by bringing the tips of the parts into contact with each other.

As described above, when the left and right doors 2, 2' are attached to the mounting base 1 using the insertion hinge of this invention constructed as described above, if the doors 2, 2' are at different levels above and below, , the protrusion 15 protruding from the base end of the pin 14 is moved through the slit 13a of the cylindrical part 13 according to the difference in level, and at the position where the pin 14 protrudes a predetermined amount from the cylindrical part 13. , the pin 14 is fixed by engaging the protrusion 15 with a predetermined engagement hook hole 13b formed at a plurality of locations along the slit 13a, and in this way, the protruding length of the pin 14 on the insertion fitting 11 side is adjusted. After that, by inserting this pin 14 into the cylindrical portion 18 on the side of the metal fitting 16, the difference in height between the upper and lower sides of the left and right doors 2, 2' can be easily corrected.

Moreover, when adjusting the protruding length of this pin 14, there is no need to use a screw or a screwdriver.

As described above, in this invention, one of the insertion fittings 11 constituting the insertion hinge 10 has a cylindrical portion 13 formed in approximately half of one side edge of the flat plate portion 12, and this cylindrical portion The portion 13 has slits 13a in the axial direction, and slits 13 at predetermined intervals along the slits 13a.
An engaging hook hole 13b is formed from the wall of a in a direction substantially perpendicular to the axial direction, and the cylindrical portion 1 formed in this way
3, attach the pin 14 by passing the protrusion 15 protruding from the base end of the pin 14 in a direction substantially perpendicular to the axial direction and engaging it with the engagement hook hole 13b through the sling 13a of the cylindrical portion 13;
The other receiver has a bottom portion 18a at approximately half of one side edge of the flat plate portion 17 of the metal fitting 16, into which the pin is rotatably inserted.
By providing the insertion hinge 10 formed with the cylindrical portion 18 having a cylindrical portion 18, when the left and right doors are respectively attached using this hinge, if the left and right doors are attached at different levels above and below, , remove the protrusion protruding from the base end of the pin from the engagement hook hole of the cylindrical part, move the pin according to the difference in the level of the door, and remove the engagement hook at the position corresponding to the moved position. By fixing the pin by engaging the protrusion protruding from the base end of the pin in the hole, the difference in the upper and lower levels of the left and right doors can be easily corrected. There is no need for a separate piece to correct the difference in height between the top and bottom of the left and right doors, and even if the difference in height between the left and right doors occurs to a degree that cannot be corrected even by using a separate piece, the insertion of this invention This can be corrected by using a hinge, and when adjusting the protruding length of the pin,
The protrusion length can be adjusted by simply pinching the pin with your fingers, without requiring any special tools such as pin fixing screws or screwdrivers.
