Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of these components are also the same. Therefore, detailed description thereof will not be repeated.
[First embodiment]

First, the overall configuration of refrigerator 100 according to this embodiment will be described with reference to Figures 1 to 3. Hereinafter, the upper side in Figure 2 will be referred to as the upper side of refrigerator 100 and each component, the lower side in Figure 1 will be referred to as the lower side of refrigerator 100 and each component, the right side in Figure 1 will be referred to as the right side of refrigerator 100 and each component, the left side in Figure 1 will be referred to as the left side of refrigerator 100 and each component, the front side of the paper in Figure 1 will be referred to as the front or front direction of refrigerator 100 and each component, and the back side of the paper in Figure 1 will be referred to as the rear or back direction of refrigerator 100 and each component.

The refrigerator 100 of this embodiment has a refrigerator compartment 110 provided in the upper part of the housing 101, and a freezer compartment 120 provided in the lower part of the housing 101. A refrigerator compartment door 111 is attached to the front of the refrigerator compartment 110, and a freezer compartment door 121 is attached to the front of the freezer compartment 120. Inside the refrigerator compartment 110 of this embodiment, a vegetable case 113 is arranged at the bottom so that it can slide back and forth.

In particular, refrigerator 100 according to this embodiment can easily switch between a state in which door 111 is opened and closed around its right end as an axis, as shown in Fig. 2, and a state in which door 111 is opened and closed around its left end as an axis, as shown in Fig. 3. The following describes the attachment structure of door 111 to housing 101.
<Installation structure of the upper end of the door>

As shown in Figure 4, in this embodiment, an upper left hinge 130L is provided at the left end of the upper front surface of the refrigerator compartment 110. More specifically, a metal hinge holding plate 131L is fixed by a bolt to the left end of the front end of the top surface 101T of the metal casing 101 that constitutes the refrigerator 100, and a hinge pin is pivoted in a hinge hole formed in the hinge holding plate 131L.

Similarly, a top right hinge 130R is provided at the right end of the upper front surface of the refrigerator compartment 110. More specifically, a metal hinge holding plate 131R is fixed by a bolt to the right end of the front end of the top surface 101T of the metal casing 101 that constitutes the refrigerator 100, and a hinge pin is pivoted in a hinge hole formed in the hinge holding plate 131R.

In this way, in this embodiment, the left hinge hole is formed in the metal hinge holding plate 131L, the right hinge hole is formed in the hinge holding plate 131L, and these two plates are positioned on the metal top surface 101T, thereby increasing the assembly accuracy of the spacing between the two hinge holes.

The following describes the configuration of the upper right hinge 130R with reference to Figures 5 to 7. In this embodiment, the hinge holding plate 131R, the resin sleeve member 133R, and the head of the hinge pin 135 are arranged in this order from bottom to top.

In this embodiment, the hinge retaining plate 131R is made of a metal plate. The rear half 131B of the hinge retaining plate 131R is fixed to the right end of the front end of the top surface 101T by three bolts 132, 132, 132. The front half 131F of the hinge retaining plate 131R is formed so as to be higher than the rear half 131B via a step 131M in the middle. A recess 131X recessed to the left is formed on the right side of the rear of the front half 131F. In other words, in a plan view, the hinge retaining plate 131R extends forward from the left side of the center in the fore-and-aft direction and then bends to the right. A hinge hole 131S is formed in the right end of the front end of the front half 131F, and a pin hole 131T is formed to the left of that.

A resin sleeve member 133R is attached to the upper surface of the front end of the upper right hinge 130R. The resin sleeve member 133R is fixed to the front and right end of the hinge holding plate 131R with a screw 134 screwed from below the hinge holding plate 131R. A hinge hole 133S is also formed in the resin sleeve member 133R. The hinge hole 133S is formed in a cylindrical shape facing downward. In this embodiment, the cylindrical portion 133H covers the inner surface of the hinge hole 131S in the hinge holding plate 131R. In other words, the hinge pin 135 is configured to rotate smoothly within the hinge hole 131S without the bottom surface of the head of the hinge pin 135 or the side surface of the body of the hinge pin 135 directly rubbing against the top surface of the hinge holding plate 131R or the inner periphery of the hinge hole 131S. In other words, the resin sleeve member 133R is sandwiched between the metal hinge pin 135 and the metal hinge holding plate 131R.

In this embodiment, the resin sleeve member 133R has a raised portion 133X formed to the left of the hinge hole 133S, and a slip-out prevention portion 133Y formed from the top of the raised portion 133X to the rear right.

In this embodiment, the hinge pin 135 has a D-shaped cut at the head and the lower part of the body. When the door 111 is closed, the hinge pin 135 is inserted into the hinge hole 131S with the cut portion 135D aligned with the anti-slip portion 133Y, and then inserted into the hinge hole 111TR at the right end of the top surface of the door 111. The hinge pin 135 rotates together with the door 111 as the door 111 opens and closes.

Because of this configuration, even if a user attempts to pull the hinge pin 135 upward from the hinge hole 131S with the door 111 open, as shown in Figure 8, the uncut portion of the hinge pin 135 hits the bottom surface of the anti-slip portion 133Y, preventing the hinge pin 135 from being pulled out of the resin sleeve member 133R, hinge holding plate 131R, or door 111. In other words, in this embodiment, the hinge pin 135 cannot be removed from the housing 101 or hinge holding plate 131R when the door 111 is open.

Of course, when the door 111 is closed, the hinge pin 135 can be pulled out without hitting the anti-slip portion 133Y, in the same state as when the hinge pin 135 is inserted, i.e., with the cut portion 135D of the hinge pin 135 facing the front of the anti-slip portion 133Y.

The configuration of upper left hinge 130L is approximately bilaterally symmetrical to upper right hinge 130R, and therefore description thereof will not be repeated here.
<Installation structure of the bottom end of the door>

As shown in Figure 9, in this embodiment, a lower left hinge 140L is provided at the left end of the lower front surface of the refrigerator compartment 110. More specifically, a metal hinge holding plate 141L is fixed by a bolt to the left end of the front end of the partition frame 103, which is provided in the approximate vertical center of the housing 101 that constitutes the refrigerator 100, and a hinge pin 145 is pivotally supported in a hinge hole formed in the hinge holding plate 141L.

Similarly, a lower right hinge 140R is provided at the right end of the lower front of the refrigerator compartment 110. More specifically, a metal hinge holding plate 141R is fixed by a bolt to the right end of the front end of the partition frame 103, which is provided in the approximate vertical center of the housing 101 that constitutes the refrigerator 100, and a hinge pin 145 is pivotally supported in a hinge hole formed in the hinge holding plate 141R.

More specifically, as shown in Figures 9 to 11, bolt holes 141H, 141H... are formed in the vertical surface of the rear part of the right hinge holding plate 141R for fixing it to the left end of the front end part of the partition frame 103 between the refrigerator compartment 110 and the freezer compartment 120. Furthermore, a hinge hole 141S into which a hinge pin 145 is inserted is formed in the horizontal surface of the front right part of the hinge holding plate 141R.

A resin cover 143R is attached to the top surface of the hinge holding plate 141R. More specifically, the resin cover 143R covers the top surface of the hinge holding plate 141R, the periphery of the side surfaces, and the inner surface of the hinge hole 141S. In other words, the resin cover 143R has a hinge hole 143S formed in a cylindrical shape downward in a portion corresponding to the hinge hole 141S of the hinge holding plate 141R.

This allows the metal hinge pin 145 to be pivoted in the hinge hole 141S via the resin cover 143R so that it does not rub directly against the hinge hole 141S of the metal hinge holding plate 141L.

The portion of hinge retaining plate 141R in front of hinge hole 141S is configured in an arc shape. In this embodiment, a substantially planar abutment portion 143X is formed in the portion of resin cover 143R that covers the portion in front of hinge hole 141S. As a result, even when door 111 is closed forcefully while pivoting on the left end, or when refrigerator 100 is transported with door 111 facing up, stopper 112R on the back of door 111 will hit planar abutment portion 143X of resin cover 143R, preventing damage.

More specifically, if the front end of the hinge hole 141S of the hinge retaining plate 141R or the resin cover 143R is arc-shaped, the stopper 112R on the back surface of the door 111 will come into point or line contact with the front end, which will likely scratch or dent the front surface of the resin cover 143R or the back surface of the stopper 112R on the door 111. In this embodiment, the front end of the resin cover 143R is flat, which means that the back surface of the door 111 will come into surface contact with the front end, which will likely scratch or dent the front surface of the resin cover 143R or the back surface of the door 111.

The configuration of the lower left hinge is approximately symmetrical to lower right hinge 140R, and therefore description thereof will not be repeated here.
Second Embodiment

Another configuration will be described in which a resin sleeve member is sandwiched between the hinge pin 135 and the metal hinge holding plates 131L, 131R. In this embodiment, a configuration will be described in which the hinge pin 135 can be easily removed from the resin sleeve member or the metal hinge holding plates 131L, 131R.

The configuration of the hinge holding plates 131L, 131R and the hinge pin 135 in this embodiment is the same as in the above embodiment. In other words, in this embodiment as well, the left hinge hole is formed in the metal hinge holding plate 131L, the right hinge hole is formed in the hinge holding plate 131R, and these two plates are positioned on the metal top surface 101T, which increases the assembly precision of the spacing between the two hinge holes.

The configuration of the upper right hinge 230R will be described below with reference to Figures 12 to 14. In this embodiment, the hinge holding plate 131R, resin sleeve member 233R, rotating member 236R, and the head of the hinge pin 135 are arranged in this order from bottom to top.

A resin sleeve member 233R is positioned on the upper surface of the front end of the right hinge holding plate 131R. A hinge hole 233S is formed in the resin sleeve member 233R. The hinge hole 233S is formed in a cylindrical shape facing downward. In this embodiment, the cylindrical portion 233H covers the inner surface of the hinge hole 131S in the hinge holding plate 131R. In other words, the hinge pin 135 is configured to rotate smoothly within the hinge hole 131S without the bottom surface of the head of the hinge pin 135 or the side surface of the body of the hinge pin 135 directly rubbing against the upper surface of the hinge holding plate 131R or the inner periphery of the hinge hole 131S. In other words, the resin sleeve member 233R is configured to be sandwiched between the metal hinge pin 135 and the metal hinge holding plate 131R.

In this embodiment, a slide portion 233X is formed facing upward at the left end of the resin sleeve member 233R. The slide portion 233X is fixed to the front end of the hinge holding plate 131R by a screw 134 inserted from below the hinge holding plate 131R, thereby fixing the resin sleeve member 233R to the front end of the hinge holding plate 131R.

The rotating member 236R is fitted from above into the slide portion 233X. The rotating member 236R is attached so that it can rotate around the slide portion 233X as an axis and slide up and down.

A slip-out prevention portion 236Y is formed on the pivoting member 236R at a position higher than the head of the hinge pin 135, extending to the right from the sliding portion 233X.

The rotating member 236R has a sharp portion 236X formed between the head of the hinge pin 135 and the resin sleeve member 233R to be inserted from behind. Further to the right of the sharp portion 236X, an operating portion 236W is formed to allow the rotating member 236R to be pinched or pressed with the fingers.

In this embodiment, when the door 111 is closed, as shown in Figures 15 and 16, an operator can push the operating portion 236W forward toward the cutout portion 135D on the back surface of the hinge pin 135. This allows the sharp portion 236X to be inserted between the underside of the head of the hinge pin 135 and the upper surface of the resin sleeve member 233R, pushing the head of the hinge pin 135 upward. At the same time, the rotation of the rotating member 236R moves the anti-slip portion 236Y forward, clearing the area above the hinge pin 135.

In this embodiment, a slit 236V is formed in the vertical direction on the right side of the pivot member 236R, i.e., between the anti-slip portion 236Y and the sharp portion 236X, and a convex portion 233V is formed on the right side of the upper end of the slide portion 233X of the resin sleeve member 233R. As shown in Figure 16, when the sharp portion 236X is inserted between the underside of the head of the hinge pin 135 and the upper surface of the resin sleeve member 233R, the anti-slip portion 236Y moves forward, clearing the area above the hinge pin 135 and positioning the convex portion 233V above the slit 236V.

In this state, as shown in Figure 17, the pivoting member 236R and the hinge pin 135 can be lifted and the hinge pin 135 can be pulled out from the hinge hole 111TR of the door 111 and the hinge retaining plate 131R.

In this embodiment, when the door 111 is open, even if an attempt is made to push the operating unit 236W forward, the front surface 236Z of the operating unit 236W hits the uncut portion of the hinge pin 135, preventing the pivoting member 236R from pivoting. Therefore, the anti-slip portion 236Y remains above the hinge pin 135, preventing the hinge pin 135 from being pulled out of the resin sleeve member 233R, hinge holding plate 131R, or door 111. Furthermore, because the protrusion 233V does not come above the slit 236V, the pivoting member 236R cannot be pulled out of the resin sleeve member 233R. In other words, when the door 111 is open, it cannot be removed from the housing 101.

The configuration of the upper left hinge is approximately symmetrical to that of the upper right hinge 230R, and therefore description thereof will not be repeated here.
[Third embodiment]

In this embodiment, we describe another configuration that makes it easier to pull the hinge pin 135 out of the resin sleeve member or the metal hinge retaining plates 131L, 131R.

The configuration of the hinge holding plates 131L, 131 and hinge pin 135 in this embodiment is the same as in the above embodiment. That is, in this embodiment as well, the left hinge hole is formed in the metal hinge holding plate 131L, the right hinge hole is formed in the hinge holding plate 131L, and these two plates are positioned on the metal top surface 101T, so the assembly precision of the spacing between these two hinge holes is high.

The configuration of the upper right hinge 130R will be described below with reference to Figures 18 to 20. In this embodiment, the hinge holding plate 131R, resin sleeve member 333R, gap member 336, and the head of the hinge pin 135 are arranged in this order from bottom to top.

A resin sleeve member 333R is disposed on the upper surface of the front end of the hinge holding plate 131R. A hinge hole 333S is formed in the resin sleeve member 333R. The hinge hole 333S is formed in a cylindrical shape facing downward. In this embodiment, the cylindrical portion 333H covers the inner surface of the hinge hole 131S in the hinge holding plate 131R. In other words, the hinge pin 135 is configured to rotate smoothly within the hinge hole 131S without the bottom surface of the head of the hinge pin 135 or the side surface of the body of the hinge pin 135 directly rubbing against the upper surface of the hinge holding plate 131R or the inner periphery of the hinge hole 131S. In other words, the resin sleeve member 333R is configured to be sandwiched between the metal hinge pin 135 and the metal hinge holding plate 131R.

In this embodiment, gap member 336 is sandwiched between the upper surface of resin sleeve member 333R and the bottom surface of the head of hinge pin 135. More specifically, gap member 336 is composed of bottom surface 336A, vertical portion 336B extending vertically upward from the left portion of bottom surface 336A, and top surface 336C extending horizontally from the upper end of vertical portion 336B toward hinge hole 131S. Top surface 336C is located at a higher position than hinge pin 135. With the right portion of bottom surface 336A sandwiched between the upper surface of resin sleeve member 333R and the bottom surface of the head of hinge pin 135, screw 334 is threaded from above into screw hole 336T in vertical portion 336B, thereby fastening gap member 336 to resin sleeve member 333R from above.

As a result, in this embodiment, the worker can remove the screw 334, lift the hinge pin 135 together with the gap member 336 upward, and pull the hinge pin 135 out of the hinge hole 111TR of the door 111 and the hinge retaining plate 131R.

More specifically, in this embodiment, the lower portion of vertical portion 336B of resin sleeve member 333R is recessed. Referring to Figures 21 and 22, after removing screw 334, the worker pushes the left portion of gap member 336 downward and, by using the principle of leverage, pushes up the right portion of gap member 336, thereby lifting the bottom surface of the head of hinge pin 135 upward, and then can pull hinge pin 135 out of hinge hole 111TR of door 111 and hinge holding plate 131R.
The hinge pin 135 may have a cut portion 135D, and the upper surface 336C of the gap member 336 may have a positional relationship with the portion 135D similar to that of the slip-out prevention portion 133Y of the first embodiment. This makes it possible to prevent the hinge pin 135 from being removed from the housing 101 or the hinge holding plate 131R when the door 111 is open.

The configuration of the upper left hinge is approximately symmetrical to that of the upper right hinge 330R, and therefore description thereof will not be repeated here.
[Fourth embodiment]

In addition to the above embodiment, it is possible to add a function that stabilizes the door 111 in the closed state by utilizing a D-cut hinge pin 135. For example, as shown in Figures 23 and 24, a pressing portion 433Z is formed on the right-side resin sleeve member 433R that abuts against the cut portion 135D of the hinge pin 135 when the door 111 is closed. More specifically, it is preferable that the tip of the pressing portion 433Z presses forward against the right portion of the surface of the cut portion 135D of the hinge pin 135 when the door 111 is closed.

This prevents the door 111 from opening by itself when vibrations or the like are applied to the door 111, as shown in Figures 23 to 25. Furthermore, when a user opens the door 111, the resistance that occurs when the pressing portion 433Z moves from the cut portion 135D to the uncut portion can be felt by the user's hand, reducing the chance of forgetting to close the door 111.

Conversely, the left-side resin sleeve member 433L also has a pressing portion 433Z that abuts against the D-cut portion of the hinge pin 135 when the door 111 is closed. More specifically, it is preferable that the tip of the pressing portion 433Z presses the left portion of the cut surface of the hinge pin 135 forward when the door 111 is closed. This reduces the possibility of the door 111 opening on its own or the user forgetting to close the door 111.

The configuration of the upper left hinge is approximately symmetrical to the upper right hinge 430R, and therefore description thereof will not be repeated here.
