Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a storage door support device used for refrigerators, showcases, etc.

Conventional technology Conventionally, the doors of this type of storage usually open to the right, but in order to meet customer needs, manufacturers are now offering a variety of types with doors that open to the left. I am doing it.

An example of the structure of the conventional storage door support bearing described above will be described below with reference to the drawings.

FIGS. 5 and 6 show the structure of a conventional storage door support bearing. In FIG. 6, 1 is the main body of the storage, and this main body 1 is equipped with a door 2 that can be opened and closed at the front.

An upper hinge 4 and a lower hinge 5 having hinge pins 3 and 3' shifted in the front-rear direction are provided on the upper and lower sides of the front pivot side of the main body 1, respectively. The upper hinge 4 and lower hinge 5 attached to this main body 1 are attached so that the lower hinge 6 is separated from the main body 1, and the pivot side of the door 2 sandwiched between these hinges 4 and 6 is attached. Hollow hinge pin receivers 6 and 6' are provided on the upper and lower sides, and the positions of the hinge pins 3 and the hinge pins 3 are shifted from each other. 7 is a spacer inserted between the lower hinge 6 and the lower hinge pin receiver 6' to smooth the rotation of the door 2. 8 is a gasket. 9
is the insulation material of door 2. 1o is a handle.

The structure and operation of the storage door support bearing configured as described above will be explained below.

First, the upper hinge pin 3 fixed to the upper hinge 4 and the lower hinge via 3' fixed to the lower hinge 5 are out of position in the front and back, so if the door 2 is open and the angle is within a certain angle, the moment will automatically Door 2 is now closed.

Problems to be Solved by the Invention However, in the above configuration, the upper and lower hinge pin receivers 6, 6' are installed in the upper and lower holes 15a of the door 2.

Since the eccentricity a is present in the door 6b, there is a problem in that the door 2 cannot be installed to open in the opposite direction by flipping the door 2 upside down by sharing the door 2 with the door 2 that opens to the right or the left. .

Therefore, in the present invention, the centers of the upper and lower hinge pin receivers are the same, and the holes for the upper and lower hinge pins are placed at predetermined positions.
It is something to be installed.

Means for Solving the Problems In order to solve the above-mentioned problems, the structure of the storage door support bearing of the present invention is a common hinge pin receiver with an internal hollow shape, and the centers of the upper and lower hinge pin receivers are the same and uneven. A core hole is provided, and the eccentric hole fits and supports the upper and lower hinge pins, allowing the door to be pivotally attached.

Function: Due to the above-described configuration, the present invention allows a single door to be commonly used as a right-opening door or a left-opening door, and even if the reverse opening specification of the door is changed at the time of manufacture by the manufacturer, the same door can be used. It can be produced without stopping the production line, and
Even if on-site changes occur due to customer requests, they can be handled in the same way.

Even for products with multiple doors, the common door allows for smooth production systems and inventory management.

Embodiment Below, the structure of a door support bearing for a storage cabinet according to an embodiment of the present invention will be explained with reference to FIGS.

In the figure, 1 is the main body, 2 is the door, and 3.3' is the upper hinge 4 and lower hinge 5 attached to the upper and lower sides of the front pivot side of the main body 1, respectively.
These are upper and lower hinge pins that are fixed to each other and eccentric in the front-rear direction. Reference numeral 11 denotes a hinge pin receiver, which is formed in a cylindrical shape and has seven flange 12 at one end, an eccentric hole 13 having an internal hollow shape shifted from the center point Q, and a rotation stopper 14 at a symmetrical position of the eccentric hole 13. is formed. Further, holes 15 and 15 into which hinge pin receivers 11 are inserted are provided at the upper and lower ends of the door 2.
', and the notches 16a and 1e are provided with holes 15 and 15' into which the detent 14 is selectively inserted.
b.

16'a and 16'b are provided.

15' is hidden from view.

Next, the operation of the above embodiment will be explained.

When installing door 2 on main body 1 as a right-hand opening door, use upper hinge 4
The upper hinge pin 3 is eccentric to the main body 1 side compared to the lower hinge pin 3' of the lower hinge 5, and the eccentric hole 13 of the upper hinge pin receiver 11 is located on the main body 1 side.
A rotation stopper 14 located in a symmetrical position with respect to 3 is fitted into a notch 16b provided in the hole 16 of the door 2, and is interposed in the upper part of the door 2 as an upper hinge pin receiver 11. Further, the lower upper hinge pin 3' of the lower hinge 6 is located on the outside of the main body 1 compared to the upper hinge pin 3 of the upper hinge 4, and the eccentric hole 13 of the lower hinge pin receiver 11 is located outside the lower hinge pin 3. ', so that the detent 14' is eccentric in the same direction as the hole 1 of the door 2.
It fits into a notch 16'a provided in the door 5', and is interposed in the lower part of the door 2 as a lower hinge pin receiver 11. In addition, when the door 2 is to open to the left, the door 2 is turned upside down and the rotation stopper 14 of the hinge pin receiver 11 and the notches 16a, 16 are opened as described above.
b, 16'a.

What is necessary is to change the position of 16'b.

Therefore, when the door is opened to the right or left, the locks 14 provided in the upper and lower hinge pin receivers 11, the notches 16a, 16b provided in the holes 15, 15' in the door,
16'a and 16'b match each other, and the hinge pins of the upper hinge 3 and lower hinge 3 are pivotally connected to the hinge pin receivers 11 that match the vertical eccentricity, and the upper hinge 3 and the lower hinge 3
′ and the door is clamped. In addition, with the above-described configuration, one type of door can serve as the upper, lower, left, and right doors, and can be applied to storages in multiple fields.

Effects of the Invention As described above, the present invention has the above-described configuration, and the vertical eccentricity can be reduced by simply attaching the hinge pin receivers fitted on the top and bottom of the door to predetermined positions with reference to the positioning holes. Therefore, there is an advantage that the required opening/closing direction can be easily selected, whether the door is opened to the right or to the left.
