<Embodiment>
An embodiment of the present invention will be described with reference to FIGS. In this embodiment, a two-door vertical refrigerator is illustrated.
In FIG. 1, a refrigerator main body 10 is composed of a vertically long heat insulating box with a front opening, and the inside is a storage room. The front opening of the storage room is divided into two upper and lower entrances, and each swings open and close. The heat insulation door 11 is mounted and supported by legs 12 arranged at the four corners of the bottom surface.
A machine room 15 is formed on the upper surface of the refrigerator body 10, and a refrigeration device installed in the machine room 15 is connected to a cooler installed in the storage room by a refrigerant pipe, and is generated by the cooler as the refrigeration apparatus is operated. The stored cold air is circulated and supplied into the storage chamber, so that the storage chamber is cooled.

  The structure of the machine room 15 will be described. At the four corners of the upper surface of the refrigerator main body 10, metal columns are erected, and panels are stretched on the left and right side surfaces and the rear surface via these columns to form a machine room 15 that opens to the upper surface and the front surface. The front panel 20 is attached to the front opening 16 of the machine room 15 so as to be openable and closable. In other words, pillars 70, which will be described later in detail, are erected on both left and right edges of the front opening 16, and the front panel 20 is attached to the left and right pillars 70 so as to be openable and closable.

As shown in FIGS. 2 and 3, the front panel 20 is configured by integrally assembling synthetic resin corner bodies 30 at both left and right ends of a panel body 21 made of a metal plate such as a stainless steel plate.
The panel main body 21 has a front plate 22 having a vertical width comparable to almost the entire height of the front opening 16 of the machine room 15 and a lateral width slightly narrower than the opening of the front opening 16. An upper surface plate 23 and a lower surface plate 24 which are bent at a right angle toward the back side are formed on both upper and lower edges of the plate, and a tip portion of the upper surface plate 23 is further bent at a right angle downward. Further, a predetermined height region (a height region of about 1/3 of the total height) of the central height portion of the front plate 22 is an arc-shaped concave surface 25 that is recessed in an arc shape on the back side.

As described above, the corner body 30 is a molded product of a synthetic resin material and is provided with a pair of symmetrical shapes. As shown in FIGS. 3 to 6, the left and right sides of the panel main body 21 are provided. A cap portion 31 that is attached to cover the end surface and a mounting plate 50 that is attached to the left and right columns 70 of the front opening 16 of the machine room 15 are integrally formed.
The cap part 31 is formed in a vertically long, substantially shallow dish shape having a peripheral wall around the periphery of the substrate 32, and the panel body 21 is provided inside the cap part 31 from the front wall 33 </ b> F to the upper surface wall 33 </ b> U and the lower surface wall 33 </ b> D. The left and right end edges 21A are fitted. Therefore, following the shape of the panel main body 21, the upper and lower corners of the front wall 33F are rounded, and the center height region of the front wall 33F is recessed in an arc shape on the back side. An arcuate recess 34A is formed. The rear wall 33R will be described later.

At positions along the front edge, upper edge, and lower edge of the substrate 32 of the cap portion 31, the edge 21 </ b> A of the panel body 21 is opposed to the front wall 33 </ b> F, the upper wall 33 </ b> U, and the lower wall 33 </ b> D with a space therebetween. A plurality of opposing walls 38 are erected to form an insertion groove 37 to be inserted. Note that the front wall 33F, the upper surface wall 33U, and the lower surface wall 33D of the cap portion 31 may be collectively referred to as a sandwiching wall 35.
There are three opposing walls 38 on the back side of the upper and lower linear portions 34B on the front wall 33F, one on the back side of the arc-shaped concave portion 34A of the front wall 33F, and closer to the back end of the upper wall 33U and the lower wall 33D. There are nine places for convenience, one on the back side of the position.

  The basic shape of the opposing wall 38 is a front square having a height slightly less than twice that of the sandwiching wall 35 described above, and is formed in a slightly thicker plate shape than the sandwiching wall 35. 35 is tapered from the position slightly rising from the base end toward the projecting end, and the entire surface from the projecting end to the base end is formed at the center in the width direction. Thus, the lightening groove 39 is cut. In other words, on both side edges of the opposing wall 38 sandwiching the lightening groove 39 on the side facing the clamping wall 35, a thick clamping surface 40 is formed on the base end side, and tapers toward the protruding end. A guide surface 41 having a tapered shape is formed.

The opposing wall 38 is provided with three types depending on the width. Three large opposing walls 38L are formed on the back side of the upper and lower linear portions 34B on the front wall 33F, with a gap in the length direction of the front wall 33F. An intermediate facing wall 38M is formed on the back side of the arc-shaped recess 34A of the front wall 33F. In addition, small opposing walls 38S are formed on the back sides of the upper wall 33U and the lower wall 33D near the back end. A pair of left and right reinforcing ribs 42 are formed on the surface side of the middle facing wall 38M.
Here, each of the opposing walls 38 is provided between the clamping surface 40 and the clamping wall 35 that faces the clamping wall 35 at an interval substantially equal to the thickness of the edge 21 </ b> A of the panel main body 21. Between the wall 35 and each opposing wall 38, an insertion groove 37 into which the edge 21A of the panel body 21 is closely inserted is formed on the back side.

On the inner surface of the holding wall 35 that constitutes one side surface of the insertion groove 37 described above, a plurality of locking projections 45 that are locked to the edge of the panel main body 21 and are prevented from coming off are formed. The locking projections 45 are formed at two locations between the formation positions of the large opposing walls 38L on the inner surface of the upper and lower straight portions 34B of the front wall 33F, and the formation of the small opposing walls 38S on the upper wall 33U and the lower wall 33D. It is formed in a total of six locations, one on the front side of the location. More specifically, as shown in FIG. 8, the locking protrusion 45 has a rectangular block shape slightly taller than the panel thickness of the panel body 21, and is formed at a substantially central portion in the depth direction of the holding wall 35. The rear surface is a locking surface 46 that is cut at a right angle, and the front surface is a tapered guide surface 47.
On the other hand, the left and right end edges 21A from the front plate 22 to the upper and lower surface plates 24 in the panel main body 21 correspond to the above-described locking projections 45, as shown in FIG. Six locking holes 27 each including a hole are formed.

As described above, the pillars 70 are erected on the left and right side edges of the front opening 16 of the machine room 15, and the mounting plates 50 of the corner body 30 provided at the left and right ends of the front panel 20 correspond to each other. It is attached to the column 70 so as to be swingable and openable.
As shown in FIG. 7, the support column 70 has a shape such as a metal angle member, and a wide side plate 72 is bent at a right angle from one side edge of the narrow front plate 71. It is symmetrical. On both upper and lower edges from the front plate 71 to the side plate 72, an upper surface plate 73A and a lower surface plate 73B are respectively bent at right angles to the inside, and each support column 70 is located on the front left and right sides of the upper surface of the refrigerator body 10. Are fixed by screwing the lower surface plate 73B.
The side plates 72 of both columns 70 are applied to fix the front end side of the side panel, and the upper surface plate 73A is applied to the case where the top panel is stretched.

A corner body 30 of the front panel 20 is attached to a front plate 71 (corresponding to a support plate of the present invention) of the support column 70 so as to be able to swing open and close and to be held in a closed posture and an open posture. Yes.
As a structure of the swing support portion on the support column 70 side, a side surface with a predetermined width is provided at a corner portion extending from the upper end portion of the front plate 71 to the upper surface plate 73A and slightly closer to the open edge side from the central portion in the width direction. A latching groove 75 (corresponding to the latching opening of the present invention) cut out so as to form an L shape is formed. A first projecting piece 76 is formed at the lower edge of the retaining groove 75 by cutting it inward at a right angle.

As a structure for holding in the closed posture, a locking opening 77 made of a slightly vertical square hole is provided at a position above the lower end of the front plate 71 by a predetermined dimension and at a position corresponding to the position directly below the hooking groove 75. Is formed. A second projecting piece 78 is formed on the upper edge of the locking opening 77 by cutting it inward at a right angle.
Further, as a structure for holding in the open posture, the rear edge portion of the upper surface of the above-described retaining groove 75 is a holding plate 79.

The structure on the mounting plate 50 side of the corner body 30 of the front panel 20 will be described with reference to FIGS. 3 and 4 again. The rear wall 33R of the cap portion 31 of the corner body 30 has a shape that is thicker than the above-described sandwiching wall 35 and is taller by a predetermined dimension. However, the predetermined region at the lower end portion of the rear wall 33R is a lower portion 49 whose height is stepped to a level slightly higher than the sandwiching wall 35, and conversely, the rear side of the lower wall 33D. Is approximately as high as the lower portion 49 described above. Further, a substantially half region on the back side of the upper surface wall 33U is also taller than the heightened portion of the lower wall 33D.
A mounting plate 50 is formed on the upper edge of the region of the rear wall 33R of the cap portion 31 excluding the low-order portion 49, and is bent at a right angle toward the back side over almost the entire height. The mounting plate 50 has a thickness approximately twice that of the rear wall 33 </ b> R, and has a protruding width that is approximately half the depth of the cap portion 31. The mounting plate 50 has a height comparable to the height of the front plate 71 of the support column 70 (see FIG. 10).

At the upper end of the protruding end edge of the mounting plate 50, a hook 51 that is hooked to the lower edge of the retaining groove 75 formed in the front plate 71 of the column 70 is formed to protrude toward the column 70 side. Yes. The hook 51 has the same thickness as the mounting plate 50 and has a thickness that can be inserted into the retaining groove 75 of the support column 70, and is bent downward at the tip of the horizontal portion 52A as shown in FIG. It is formed in a bowl shape provided with a vertical portion 52B.
A first protrusion formed on the lower edge of the retaining groove 75 between the back side of the vertical part 52B of the hook 51, specifically, between the inner surface of the vertical part 52B and the protruding edge of the mounting plate 50. The piece 76 is fitted almost tightly.

On the lower edge of the horizontal portion 52A of the hook 51, an escape recess 55 is cut out upward at the end portion position on the vertical portion 52B side. The hook 51 is swingable in the opening direction (counterclockwise direction in FIG. 11) while the corner 55R of the escape recess 55 is received by the first projecting piece 76, and the corner 55R is rounded. It has been.
The vertical portion 52B is set such that the length L from the back edge (upper edge) to the tip of the escape recess 55 is as short as possible within a range in which the vertical portion 52B is not detached from the first projecting piece 76. . Further, the outer surface side of the lower end portion of the vertical portion 52B is obliquely removed to form a tapered surface 54 that is tapered. This significance will be described later. The tip 56 of the vertical portion 52B is also rounded.

  The front panel 20 is held in an open state in a substantially horizontal posture. Therefore, a fitting groove 53 is formed by cutting downward on the upper surface of the mounting plate 50, that is, on the base end side of the surface extending from the upper surface of the horizontal portion 52 </ b> A of the hook 51. When the front panel 20 takes a substantially horizontal opening posture, the fitting groove 53 is opened toward the support column 70, and the holding plate 79 provided on the support column 70 can enter from the front. The groove width of the fitting groove 53 is set to about 2.5 times the thickness of the holding plate 79 with a margin.

  When the front panel 20 is released from the closed state shown in FIGS. 10 and 11, the hook 51 is shown while the corner 55 </ b> R of the escape recess 55 is received by the first projecting piece 76 as described above. 11 is swung counterclockwise and is swung by a predetermined angle (about 60 degrees), as shown in FIG. 12, the tip 56 of the vertical portion 52B is in contact with the first projecting piece 76 on the back surface of the front plate 71. After that, the tip 56 of the vertical portion 52B is in sliding contact with the back surface of the front plate 71, and the corner portion 55R of the relief recess 55 is in sliding contact with the first protrusion 76 toward the tip. Then, as shown in FIG. 13, after swinging about 80 degrees, it is further swung in the opening direction while popping out from the tip of the first projecting piece 76 first. When the corner 55R of the escape recess 55 protrudes from the tip of the first projecting piece 76, the front panel 20 sinks and the projecting edge of the mounting plate 50 is received by the first projecting piece 76, and the fitting groove 53 is held at this time. Since it faces the plate 79, the holding plate 79 enters the insertion groove 53 by subsequently pushing the front panel 20 toward the support column 70, and as shown in FIG. 14 and FIG. The lower edge of the figure hits the lower surface of the holding plate 79, and the projecting end edge of the mounting plate 50 is received by the first projecting piece 76. It is held in an open state.

  Based on the above-described operation, the relief recess 55 provided in the hook 51 is changed from the hooked state shown in FIG. 11 to the corner portion 55R of the relief recess 55 as shown in FIG. While swinging in the opening direction until it jumps out from the tip of the piece 76, the tip of the first protruding piece 76 is made to enter so that it can escape so as not to interfere with the hook 51. .

On the other hand, the significance of limiting the vertical portion 52B of the hook 51 to the predetermined length L and cutting the tapered surface 54 on the outer surface on the tip side of the vertical portion 52B are as follows.
For example, when the front panel 20 is vigorously opened and a large swinging force is applied in the opening direction from the state shown in FIG. 12, the tip 56 of the vertical portion 52B moves on the back surface of the front plate 71 as shown in FIG. Ascending and swinging about the front end 56 of the vertical portion 52B, the holding plate 79 enters the fitting groove 53 at a timing at which the front panel 20 exceeds the horizontal posture, and further obliquely upward (100 to 100). It can be opened until it takes about 110 °.

  Here, as a comparative example, as shown in FIG. 17, when the length of the vertical portion 3 of the hook 2 in the front panel 1 is longer than that in the above embodiment and the tapered surface is not formed, the front panel 1 is After the front end of the vertical portion 3 hits the back surface of the front plate 71, it swings around the front end of the vertical portion 3 and swings to a position slightly exceeding 90 °. 79 enters. In other words, this state is a state in which the front end of the vertical portion 3 and the inner edge of the insertion groove 53 are sandwiched between the front end edge of the front plate 71 and the holding plate 79 and the swinging is restricted. If the swinging force is further applied from the state, the hook 51 may be damaged by being squeezed at the portion where the fitting groove 53 is formed.

Therefore, as shown by a chain line 3A in FIG. 17, when the length of the vertical portion 3 is shortened, a margin is created between the tip of the vertical portion 3 and the back surface of the front plate 71, and the front panel 20 is further increased accordingly. It can swing in the opening direction.
Further, as shown by a chain line 3B in the figure, even if the length of the vertical portion 3 is long, if the tapered surface is cut on the outer surface of the vertical portion 3, the front end side outside the vertical portion 3 is rearward. The hook 2, that is, the front panel 1 can further swing in the opening direction.

As described above, the significance of the fact that the vertical portion 52B of the hook 51 of this embodiment is limited to a predetermined length and the tapered surface 54 is cut on the outer surface of the vertical portion 52B is that the front panel 20 is opened. A swing angle until the swing in the direction is restricted is gained, and an accident of breaking the hook 51 when the front panel 20 is flipped up vigorously is avoided.
In this embodiment, since both structures are adopted, it can be said that it is more effective in increasing the swing angle.

Further, in order to hold the front panel 20 in a closed state in a vertical posture, the mounting plate 50 is locked to a locking opening 77 formed in the front plate 71 of the column 70 at a position above the lower end of the mounting plate 50 by a predetermined dimension. A holder 57 is formed. The holder 57 includes an elastic locking piece 58 and a restricting portion 64.
The elastic locking piece 58 is formed by inserting two slits 59 in a horizontal posture parallel to each other from the end edge of the mounting plate 50 toward a position closer to the inner inner edge. An arm portion 60 is formed therebetween, and the distal end side of the arm portion 60 is formed so as to protrude slightly from the edge of the mounting plate 50, and forms a substantially semicircular shape on the upper surface of the extended end of the arm portion 60. This is a shape in which a locking head 61 is formed. Here, as shown in FIG. 4, the horizontal dimension x from the edge of the mounting plate 50 to the top 61 </ b> A of the locking head 61 is as shown in FIG. 5 from the back surface of the front plate 71 of the column 70. It is formed to be slightly larger than the dimension X up to the protruding end of the second protruding piece 78 formed to protrude backward on the upper edge of the locking opening 77.
A circular hole 62 having a diameter larger than the width of the slit 59 is continuously provided on the outer side of the back end of both the slits 59, so that both sides of the base of the arm portion 60 are rounded. Yes.

Below the position where the elastic locking piece 58 is formed, a restricting portion 64 is formed so as to protrude with an interval comparable to the width of the slit 59. Receiving the head 61, the arm 60 functions to restrict excessive bending. A tapered guide surface 65 is formed on the lower surface of the restricting portion 64.
Thus, the locking head 61 and the restricting portion 64 of the elastic locking piece 58 constituting the holder 57 can be fitted together with the locking opening 77 of the front plate 71 of the support column 70, The height dimension between the top 61A of the head 61 and the root position of the lower surface of the restricting portion 64 is the height dimension between the lower surface of the second projecting piece 78 and the lower edge of the locking opening 77. It is set to be a little larger.

In addition, on the inner surface side of the mounting plate 50, a thinned recess 67 is formed in a region between the formation positions of the hook 51 and the holder 57 and a region below the formation position of the holder 57.
Further, as described above, the mounting plate 50 is formed by being bent at a right angle from the protruding end of the tall rear wall 33R of the cap portion 31 toward the back side, in other words, as shown in FIG. The mounting plate 50 is formed by retracting inward from the outer surface of the substrate 32 of the cap portion 31 by a dimension y. As a result, on the back side of the corner body 30, an operation recess 68 is formed that is positioned outside the entire height of the mounting plate 50 so that the finger of the operator's hand can be inserted.

  Subsequently, the operation will be described. First, the front panel 20 is assembled as follows. As shown in FIG. 3, left and right corner bodies 30 are arranged on the left and right sides of the panel body 21, and the edge 21 </ b> A of the panel body 21 is connected to the cap portion 31 of the corner body 30 as shown by the arrow in FIG. 8. It is inserted into the formed insertion groove 37. The edge 21 </ b> A of the panel body 21 is guided to the insertion groove 37 along the guide surface 41 of the opposing wall 38, hits the guide surface 47 of the locking projection 45, and then pushed further into the insertion groove 37. It rides on the locking projection 45 while elastically spreading. When the predetermined amount is pushed in and the locking hole 27 reaches the position of the locking projection 45, the locking projection 45 fits into the locking hole 27 while the insertion groove 37 is narrowed by the restoring elasticity as shown in FIG. The corner body 30 is attached to the end edge 21 </ b> A of the panel body 21 in a form in which the cap portion 31 covers the end surface of the panel body 21. As shown in FIG. 2, the front panel 20 is formed by assembling the corresponding corner bodies 30 to the left and right end edges 21 </ b> A of the panel body 21 as described above.

  The form in which the front panel 20 is attached to the front opening 16 of the machine room 15 is as follows. When mounting, the front panel 20 is in an oblique posture, and the hooks 51 provided at the upper ends of the mounting plates 50 of the left and right corner bodies 30 are inserted into the L-shaped hooking grooves 75 of the corresponding columns 70. After that, the corner portion 55R of the relief recess 55 of the hook 51 is placed on the first projecting piece 76, and the front panel 20 is gradually raised while holding the lower end portion of the corner body 30 with fingers. Oscillate as follows.

When the front panel 20 approaches the standing posture, the holders 57 provided on both corner bodies 30, specifically, the locking head 61 and the restricting portion 64 of the elastic locking piece 58, the front plate 71 of the corresponding column 70. The second projecting piece in which the locking head 61 is cut and raised from the upper edge of the locking opening 77 while the arm portion 60 of the elastic locking piece 58 is elastically bent downward. The lower surface of 78 is brought into sliding contact with the restricting portion 64. As shown in FIG. 10, when the front panel 20 takes an upright posture and the edge of the mounting plate 50 of the corner body 30 comes into contact with the front plate 71 of the column 70, the root of the lower surface of the restricting portion 64 is engaged. While being pressed against the lower edge of the stop opening 77, the top 61 </ b> A of the locking head 61 of the elastic locking piece 58 passes through the tip of the second protruding piece 78, so that the arm portion 60 is elastically restored slightly upward. While moving, the tip end of the second projecting piece 78 is locked and prevented from coming off at a position slightly lowered from the top 61 </ b> A of the locking head 61.
On the other hand, on the upper end side, as shown in FIG. 11, the first projecting piece 76 on the lower edge of the latching groove 75 fits almost tightly on the back side of the vertical portion 52B of the hook 51, and the upper end side does not rattle. The front panel 20 is held in the closed position.

  When the front panel 20 is opened, when the lower end portions of the corner bodies 30 on both sides are picked up and the lower end portions of the front panel 20 are lifted to the near side from the state shown in FIGS.
