In the above conventional device, the locking piece provided on the corner body to elastically lock the front panel with respect to the support column has a structure that protrudes greatly from the root, so that it is inconvenient during transportation or assembly work. There is a risk of damaging it by hitting it in preparation. In order to avoid this, a means has been proposed in which a rod holder is provided on the column side and the holder portion provided at the lower end of the corner body is elastically fitted, but there is a problem that the cost increases due to the provision of the rod holder. there were.
The present invention has been completed based on the above-described circumstances, and an object of the present invention is to reinforce the structure of the portion for attaching the front panel to the support column without incurring high costs.

The machine room structure of the storage of the present invention is provided with a machine room having an opening on the front surface on the upper surface of the storage body, and a front panel is attached to the front opening of the machine room so as to be openable and closable. Columns are set up on the left and right side edges of the front opening of the front panel, a latching portion is provided at the upper end of each column, and a locking opening is provided at the lower end. A corner body made of synthetic resin is provided, and a hook that is swingably hooked on the hook portion of the column is provided on the upper end side of the edge facing the column in each corner body, and a lower end On the side, an elastic locking piece that elastically locks in the locking opening of the support column is provided, and the elastic locking piece is directed inward from the edge of the corner body facing the support column. Formed between two slits An elastic deflectable tip of the arm portion which has a characteristic where the locking portion for locking the rim of said locking aperture has a shape that is provided.

To attach the front panel to the front opening of the machine room, after hooking the hooks of both corner bodies to the latching part of the corresponding column and swinging the front panel to take a vertical posture, While the arm part of the elastic locking piece provided at the edge is elastically bent, the locking part at the tip enters the locking opening of the other column, and when it takes a predetermined posture, the arm part moves back and engages. The stopper is attached by being locked to the lip of the locking opening.
The elastic locking piece provided on the corner body to attach the front panel to the column has an elastically deformed arm part arranged inside the edge of the corner body, and it protrudes from the edge almost at the tip side. Since it is formed in a form that only has a stop, it is restricted that the arm is deformed even when the elastic locking piece is inadvertently hit against a foreign object during conveyance or assembly work. In addition, it is possible to prevent damage and the like. That is, the structure of the portion for attaching the corner body of the front panel to the support can be enhanced without using a separate part such as a rod holder, thereby contributing to a reduction in manufacturing cost.

The following configuration may also be used.
(1) A restriction for restricting the arm portion from being bent excessively by receiving the locking portion of the elastic locking piece at a position below the formation position of the elastic locking piece at the edge of the corner body. A protruding portion is provided, and the restricting portion can enter the locking opening of the support column together with the locking portion of the elastic locking piece.
When the front panel with the upper end supported by a hook is swung in a vertical position, the arm part of the elastic locking piece provided on the corner body is elastically bent, and the locking part at the tip of the front panel also serves as a support column. After that, the arm part moves backward and the locking part is locked to the lip of the locking opening, but when the arm part is elastically bent, the locking part hits the restricting part and is received. As a result, excessive bending of the arm portion is restricted, and breakage at the base of the arm portion is prevented.

(2) A circular hole having a diameter larger than the width of the slit is continuously provided at the back end of the slit cut to form the arm portion of the elastic locking piece, and both side surfaces at the base of the arm portion Is rounded. Since both sides of the base of the arm are rounded, stress concentration on the base caused when the arm is bent is alleviated, and the arm is prevented from being broken from the base.
(3) An operation recess that allows a finger to be inserted is cut out at a lower end portion of an edge of the corner body facing the support column. The lower corner of the front panel can be picked while putting a finger into the operation recess, which is convenient when the front panel is swingably opened and closed about the upper edge side.

(4) The upper edge of the locking opening of the support column is provided with a protrusion protruding on the back side, and the upper surface of the locking portion of the elastic locking piece is formed as an arcuate bulging surface, The elastic locking piece is prevented from coming off when the protruding end of the protruding piece is locked at a position descending from the top of the bulging surface of the locking portion to the near side.
While the elastic locking piece can be prevented from coming off, the front side of the top has a so-called forward taper shape, so that it can be removed relatively easily while elastically bending the arm portion by pulling with a predetermined force or more. At the time of locking, the corner body is pulled downward, the hook is elastically pressed against the hooking portion of the support column, and the corner body and thus the front panel is held in a closed state without rattling.

<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 in which a metal angle member is erected, and is a shape in which a wide side plate 72 is bent at a right angle from one side edge of a narrow front plate 71. It is symmetrical. At both upper and lower edges extending from the front plate 71 to the side plate 72, mounting plates 73 are formed by bending at right angles to the inside, and each support column 70 is set up at the left and right corners on the front side of the upper surface of the refrigerator body 10. The lower mounting plate 73 is fixed by screwing.
The side plates 72 of both the columns 70 are applied to fix the front end side of the side panel, and the upper mounting plate 73 is applied when the top panel is stretched.

On the other hand, the front plate 71 of the column 70 is applied to mounting the corner body 30 of the front panel 20. Therefore, it is cut out so as to form a side L shape with a predetermined width at a corner portion extending from the upper end portion of the front plate 71 to the upper mounting plate 73 and a little closer to the open edge side from the central portion in the width direction. A hooking groove 75 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.
At a position above the lower end of the front plate 71 by a predetermined dimension and corresponding to a position directly below the hooking groove 75, a locking opening 77 made up of a slightly vertically long square hole 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.

  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 column 70 (see FIG. 12).
At the upper end of the mounting plate 50, a hook 51 that is hooked in a hooking groove 75 formed in the front plate 71 of the support post 70 is formed so as to protrude toward the back side. The hook 51 has the same thickness as the mounting plate 50 and has a downward-facing saddle shape. A concave groove 53 is formed on the upper surface of the base of the horizontal portion 52A, and the outer surface side of the lower end of the vertical portion 52B is tapered. It is set as the taper surface 54 of this. Further, a stepped groove 55 whose front side is lowered by one step is formed inside the vertical portion 52B.

On the other hand, a holder 57 that is locked to a locking opening 77 formed in the front plate 71 of the support column 70 is formed at a position above the lower end of the mounting plate 50 by a predetermined dimension. 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. 12 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, as shown in FIGS. 10 and 11, the lower part is lifted to the near side and the front panel 20 is swung in a substantially horizontal posture, and then the hook 51 is pushed forward to form the concave groove 53 at the base of the hook groove. 75, when the upper end of the mounting plate 50 is received by the first projecting piece 76 cut and raised from the lower edge of the retaining groove 75 to the back side, the front panel 20 is moved by its own weight. The front panel 20 is held in an open state in a substantially horizontal position.

  To close the front panel 20, from the open state shown in FIGS. 10 and 11, the corner bodies 30 on both sides are picked while putting fingers into the operation recesses 68, and the front panel 20 is first pulled forward to form the grooves 53. Is removed from the front edge of the retaining groove 75. Then, the first projecting piece 76 at the lower edge of the retaining groove 75 enters the stepped groove 55, and the front panel 20 can swing in the clockwise direction around the first projecting piece 76. While holding the lower end of the body 30 with a finger and supporting it, the front panel 20 is swung so as to gradually take a standing posture.

  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, correspond to 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. 12, 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, the first projecting piece 76 on the lower edge of the latching groove 75 is tightly fitted to the full width of the stepped groove 55 of the hook 51, thereby the front panel 20 is brought into the closed position. It will be held.

  When the front panel 20 is opened again, when the lower end portions of the corner bodies 30 on both sides are picked up and the lower end portion of the front panel 20 is lifted to the near side from the state of FIG. Since the upper surface of 61 has a semicircular shape and the front side of the top 61A has a so-called forward taper shape, when pulled with a force of a predetermined level or more, the arm portion 60 is elastically bent downward to cause the locking head 61 to be second. While being brought into sliding contact with the lower surface of the projecting piece 78, the restricting portion 64 can be pulled out from the locking opening 77 to the near side. Subsequently, after the lower side is lifted to a substantially horizontal posture, the hook 51 is pushed into the latching groove 75 as described above, and the concave groove 53 at the base is formed into the latching groove 75 as shown in FIGS. Can be held in the open position.

  According to the present embodiment, the elastic locking piece 58 provided on the corner body 30 to attach the front panel 20 to the column 70 is configured so that most of the arm portion 60 that is elastically bent is the edge of the mounting plate 50 of the corner body 30. Since only the locking head 61 on the front end side protrudes substantially from the end edge, the elastic locking piece 58 is used as a foreign object during transportation or assembly work. Even in the case where the arm portion 60 is inadvertently bumped, the deformation of the arm portion 60 is particularly restricted, so that damage or the like is prevented. That is, the structure of the portion for attaching the corner body 30 of the front panel 20 to the support column 70 can be enhanced without using another part such as a rod holder, which can contribute to the reduction of the manufacturing cost.

The restricting portion 64 is provided below the position where the elastic locking piece 58 is formed, and when the arm portion 60 is elastically bent, the locking head 61 hits the restricting portion 64 so that the arm portion 60 is excessively bent. Therefore, it is possible to prevent the arm portion 60 from being broken at the base.
Since both sides of the base of the arm 60 are rounded, the stress concentration on the base that occurs when the arm 60 is bent is alleviated, and the arm 60 may be broken from the base in the same manner. Is prevented.
On the back side of the corner body 30, an operation recess 68 is formed so that an operator's finger can be inserted. Therefore, the lower corner of the front panel 20 can be gripped while inserting the finger into the operation recess 68. This is convenient when the front panel 20 swings around the upper edge side.

  As shown in FIG. 12, the structure of the portion where the elastic locking piece 58 is elastically locked to the locking opening 77 of the support column 70 is at a position slightly lowered from the top 61A of the locking head 61. Since the tip end of the second projecting piece 78 is locked, the elastic locking piece 58 can be prevented from coming off, while the front side of the top 61A has a so-called forward taper shape. If it pulls with the force of this, it can remove comparatively easily, making the arm part 60 elastically bend. Further, at the time of locking, the corner body 30 is pulled downward, and the stepped groove 55 of the hook 51 is elastically deformed by the first projecting piece 76 projecting from the lower edge of the retaining groove 75 of the column 70. Thus, the corner body 30 and thus the front panel 20 are held in a closed state without rattling.
