Arrangement comprising a door member and a main body

Abstract: An arrangement comprising a door member (401) and a main body (3) is provided. The arrangement is usable in particular for a refrigerator.

Description: The present invention generally relates to an arrangement comprising a door member and a main body, mainly for use in a refrigerator, which is arranged to open or close the door member at either desired side of the door member. Figs. 17 and 18 illustrate respectively a door member and a main body of representative double-side openable refrigerators of prior art. In Fig. 17, hinge pins 20 and 20 are provided at the right and left corners of respective opposite upper and lower end portions of a door member 10. The hinge pins 20 are freely projectable upward or downward. Moreover, the hinge pins 20 are received by respective bearing recessed portions 40 each formed in a part of a main body 30 confronting to the upper or lower end portion of the door member 10. When either one of operating handles 50 provided in the door member 10 is rotated, either of the right and left hinge pins 20 are slipped off from the corresponding bearing recessed portions 40, so that the door member 10 becomes operable. In Fig. 18, the refrigerator has a middle frame 80 which is bored at the central part thereof and sandwiched between a main body 60 and a door member 70. The middle frame 80 is pivotally fixed to the main body 60 at one lateral side of the right and left sides thereof, and also pivotally fixed to the door member 70 at the other side thereof. When one of right and left operating handles provided in the door member 70 is rotated, only the door member 70 can be rendered openable at one side, while the door member 70 and the middle frame 80 are all together rendered openable at the other side. In the prior art of Fig. 17, however, a pair of the movable handles 50 are required to switch the opening side of the door member 10, and accordingly the construction of the door member becomes disadvantageously complicated. Moreover, since the door member 10 cannot be opened from inside, such a dangerous accident that an infant is confined within the main body 30 cannot be avoided. Furthermore, there is incorporated a coupling mechanism in the door member 10 for the operating handles 50 and the hinge pins 20, and therefore the adiabatic efficiency of the door member is deteriorated. Meanwhile, in the prior art of Fig. 18, two packings, namely, one between the main body 60 and the middle frame 80, and the other between the middle frame 80 and the door member 70 are necessitated, and consequently the whole door member becomes thick, thereby causing the deterioration of the adiabatic efficiency of the door member. GB-A-2 149 488 relates to a method of fabricating heat insulation housing for a refrigerator. Thereby, an insulation housing comprising an inner casing having an opening on the front surface thereof, a left-side steel plate, a right-side steel plate, a rear plate, a bottom plate, a ceiling plate and left and right flanges formed at the left and right ends of the front surface of the inner casing, are disclosed. A thermal insulator is filled in a space formed among the inner casing, the left-side plate, the right-side plate, the rear plate, the bottom plate and the ceiling plate. US-A-4 503 583 relates to an enclosure with double-acting hinge mechanism having an overcentered latch. The enclosure structure comprises a first hinge pin means fixed at one side of the opening, a second hinge pin means fixed at the opposite side of said opening, first and second latch members pivotally mounted on opposite sides of a door, latch means for retaining the hinge pin means in pivotal relationship with the door and locking means operably associated with said latch members. The present invention has been developed with a view to substantially eliminating the disadvantages inherent in the prior art devices. The present invention is to provide an arrangement as claimed in claim 1 comprising i.a a door member and a main body which comprises hinge means composed of hinge plates and hinge pins projected from the hinge plates and mounted through a mounting plate for hinge use on both the right, left end portions of a main body on which said door member is mounted, engaging grooves provided in the door member into which the hinge pins are detachably engaged from the open side of the door member, the door member being opened or closed from the optional right or left side, a reinforced member extending along the vertical direction of the main body and mounted on the inner wall portion of the main body external shell, and a mounting plate for hinge use secured onto the reinforced member. Also, a still another modified embodiment, the present invention, is to provide a door member which comprises hinge pins projected from and mounted on both the right, left end portions of a main body on which said door member is mounted and engaging grooves provided in the door member into which the hinge pins are detachably engaged from the open side of the door, the door member being opened or closed from the optional right or left side, and the door member including frame members composed of two pairs of opposed sashes, which, the adjacent sash pair are respectively secured through an engagement member, and at least more than three sashes are integrally secured with the use of engagement member.

Before the description of the present invention proceeds, it is to be noted that like parts are designated by like reference numerals throughout the accompanying drawings. Fig. 1 is a perspective view showing the outside appearance of a main body according to a first embodiment of the present invention. Fig. 2 is a dismantled perspective view for illustrating the mounting condition of a hinge in a frame of the first embodiment of the present invention. Fig. 3 is a cross-sectional view of the hinge mounting portion. The embodiment is arranged in e.g. a refrigerator, whose door may be opened or close from the optional right or left side. A hinge composed of hinge plates 102A,102B and hinge pins 2A, 2B projected from the hinge plates 102A,102B are mounted through a mounting plate 305 for hinge use on both the right, left end portions of the main body 3. Engagement grooves into which the hinge pins 2A, 2B are detachably engaged from the open side of the door 1 are provided on the door not shown. In the embodiment, in order to have the smooth opening, closing operations of the door, the strength of the hinge portion is increased to reduce the displacement caused by the load of the door 1. As shown in Fig. 3 , aluminum sashes 306 as a reinforcing member are fixed along the vertical direction of the main body 3 into the inner wall portion of the so-called right or left flange portion of the outer shell of the main body 3 of the refrigerator, with the mounting plate 305 for hinge use being secured with screws 307 onto the aluminum sashes 306. The aluminum sashes 306 as the reinforcing member are formed by an extrusion molding operation into one with an engagement piece on it so that it may be engaged into the end portion 311A of the outer shell 320 of the main body 3. The mounting plates 305 for hinge use are secured onto the aluminum sashes 306 with screws 307 and also, are secured with screws onto a compartment portion 340 which partitions the respective chambers such as refrigerating chamber, freezing chamber, etc. A center plate 306 is mounted to cover the compartment portion 340 onto which the mounting plate 305 for hinges are secured, with the hinges being mounted on the mounting plate 305 for hinge use with screws 310 from above the center plate 360. In this manner, the mounting plates 305 for hinge use are secured onto the compartment portion 340 and also, are adapted to be mounted onto the aluminum sashes 306 as reinforced members mounted on the inner wall portion of the outer shell 320 of the main body 3, so that the door load to be applied upon the mounting plates 305 for hinge use is dispersed even upon the vertically extending aluminum sashes 306 so as to increase the strength of the hinge portion and reduce the displacement caused through the door load, thus allowing the door to be smoothly opened, closed. Fig. 4 and Fig. 5 are views corresponding to Fig. 2 and Fig. 3 in another embodiment of the present invention. In this embodiment, the reinforcing member is bent into "<" shape through a press processing operation into a steel plate 312. The steel plates 312 are mounted on the inner wall portion of the outer shell 320 of the main body 3 with rivets 313, with the mounting plates 305 for hinge use being adapted to be secured with screws 307 onto the steel plates 312 through the plate members 314. The other construction is similar to that of the above-described embodiment. In addition, the other modified embodiments are shown in Fig. 6 to Fig. 9 . Fig. 6 is a perspective dismantled view showing the respective members constituting the main body of a refrigerator in accordance with the present embodiment. Fig. 7 is a partial perspective view showing how the compartment wall is mounted. Fig. 1 is a perspective whole view showing the assembled condition. Fig. 8 shows a sectional view taken along the line IV - IV line of Fig. 1. In Fig. 6 the main body 3 of a refrigerator has an outer shell with an opening portion in the front face thereof, composed of a top face plate 321, a bottom face plate 322 (see Fig. 1 ), a right-side plate 323, a left-side plate 324, a rear face plate (not shown), etc. an inner box 330 integrally mounted with composite resin, etc., and having also an opening portion in the front face, a compartment wall 340 for dividing the inner space of the inner box 330 into upper, lower directions to form a plurality of receiving chambers, a compartment reinforcing plate 350 mounted on the front face of the compartment portion 340, a center plate 360 (see Fig. 21) mounted on the front face of the compartment reinforcing plate 350. It is to be noted that in the present embodiment, an adiabatic material 390 (see Fig. 7 ) for preventing the dewing is interposed into between the compartment reinforcing plate 350 and the center plate 360. Double flange portions 326A, 326B projected in the inner direction along the opening face are formed on the peripheral edge of the front face opening portion of the outer shell constructed by the top face plate 321, a bottom face plate 322, right-side plate 323, a left-side plate 324 and a rear face plate. Also, approximately horizontal upper flange 323A and lower flange 326B each being directed inwardly are formed on the upper end edge and the lower end edge of the right-side plate 323 and left-side plate 324 are formed and a rear flange 326E for engaging each of the right, left side edge of the rear face plate are formed on the rear end edge. Also, the double flange portion 326A, 326B are formed through the bending operation of the respective tip end edges of the top face plate 321, the lower face plate 322, the right-side plate 323 and the left-side plate 324 constituting the outer shell. Namely, as shown in Fig. 8 , the tip edge is bent inwardly along the opening face, and also is bent rearwardly to form the front face side flange portion 326A and the tip end portion is extended rearwardly along the each plate face and is erected inwardly for forming the rear face side flange portion 326B, resulting in almost ]-shape in section as the whole. Namely, the engagement groove 327 is formed by the front face side flange portion 326A and the rear face side flange portion 326B. Also, the rear face side flange portion 326B formed on the right-side plate 323 and the left-side plate 324 is supported by a long flange reinforcing plate 312 of an approximately L-shaped (in section) which is secured with screws in its one side piece onto the right-side plate 323 and left-side plate 324. The flange reinforcing plate 312 is formed across approximately whole length in the height direction of the right-side plate 323 and the left-side plate 324. And a plurality of compartment fixing plates 329 (in the present embodiment, they are provided in two upper, lower locations) projected towards the inner direction are secured with screws in the proper location (described later) of the flange reinforcing plate 312. The tapped holes 329A for screwing the screws into the compartment fixing plate 329 are formed, with the forming position of the tapped hole 329A are set to be located in a given interval (ℓ3) from each plate face of the right-side plate 323 and the left-side plate 324. And when the right-side plate 323 and the left-side plate 324 are mounted on the inner box 1 through the compartment fixing plate 329, the right-side plate 323 and the left-side plate 324 are to be equally divided in the width direction from the central line L (see Fig. 1 ) of the main body. The flange portion 331 projected in the external direction along the opening face is formed on the peripheral edge of the opening portion of the inner box 330. As shown in Fig. 8 , the flange portion 331 is formed into an inversely U-shaped bent (in section) with the front face side being open. Also, a compartment inserting groove 332 for insertingly supporting three peripheral edges (except for the front face) of the compartment wall 340 is formed in the upper portion thereof. The compartment wall engagement portion 333 for engaging and supporting both the right, left side portions of another compartment wall 340 is formed in the lower portion. An opening portion 334 into which the tip end portion of each compartment fixing plate 329 mounted on the right-side plate 323 and left-side plate is inserted is formed in the front end portion of the compartment wall inserting groove 332 and the compartment wall engagement portion 333. The compartment reinforcing plate 350 and the dressing plate 360 for positioning (namely, width limit of the main body 3) of the right-side plate 323 and the left-side plate 324 constituting the outer box, preventing the deformation of the main body 3, reinforcing the rigidity thereof are secured onto the front face of the compartment portion 340 with screws 351. A coupling portion 352 for connection through the compartment fixing plate 329 and screws is formed on both the right, left end portions of the compartment reinforcing plate 350 with tapped holes 352A being formed in the proper positions of the coupling portion 352. The forming position of the tapped hole 352A is set (see Fig. 8 ) to become equal in interval in (l1) in the width direction from the central line L of the inner box 330, i.e., the box member of the main body 3. And the tapped holes 329A formed in the compartment fixing plate 329 is brought into conformity with the tapped holes 352A formed in the coupling portion 352 through the superposition of the compartment fixing plate 329 on the coupling portion 352 of the compartment reinforcing plate 350. The size between the right-side plate 323 and the left-side plate 324 is set to become the required width size l2 [=2X(ℓ1+ℓ3)] of the main body 3 through the engagement of the screws 307 into the tapped holes 329A, 352A. Namely, the forming position of the tapped hole 329A of the compartment fixing plate 329 and the tapped hole 352A of the coupling portion 352 are correctly determined as described hereinabove so that the right-side plate 323 and the left-side plate 324 may be distributed equally in the width direction from the central-line L and the fixing of the required width size (l2) as the main body 3 is to be effected at the same time simply through the mounting of the right-side plate 323 and the left-side plate 324 on the inner box 330 through the compartment fixing plate 329 and the compartment reinforcing plate 350. A coupling portion 362 for connection through the flange portion 326A on the front face side formed in the right-side plate 323 and the left-side plate 324, and the screws are formed on both the right, left end portions of the center plate 360, with the tapped holes 362A being formed in the proper locations of the coupling portion 362. Also, the tapped holes 326A are formed even in the flange portion 362A on the front face side corresponding to the coupling portion 362. The procedure of assembling the refrigerator of such construction as described hereinabove will be described hereinafter. First, the compartment portion 340 with the compartment reinforcing plate 350 mounted with screws 351, 351 on the front face thereof is inserted into the insertion groove 332 of the compartment portion of the inner box 330. Thereafter, the flange portion 331 formed into the front face opening portion of the inner box 330 is engaged into the insertion groove 327 which is composed of the double flange portion formed on the upper face plate 321, the lower face plate 322, the right-side plate 323, the left-side plate 324 and the rear face plate so as to form the outer shell with the inner box 330 being contained therein. At this time, the tip end portion of the compartment fixing plate 329 mounted on the right-side plate 323 and the left-side plate 324 is provided into the inner box 330 through the compartment wall insertion groove 332 of the inner box 330 and the opening portion 334 formed in the compartment wall engagement portion 333 and is positioned so as to be superposed onto the coupling portion 352 of the compartment reinforcing plate 350 mounted on the front face of the compartment portion 340. The tapped holes 329A formed into the compartment fixing plate 329 is brought into conformity to the tapped holes 352A formed in the coupling portion 350 to engage the screws 370 into the tapped holes 329A, 352A so as to integrally secure the right-side plate 323 and the left-side plate 324 onto both the right, left outer sides of the inner box 330. Accordingly, the right-side plate 323 and the left-side plate 324 are to be mounted with constant interval (ℓ1+ℓ3) in the width direction from the central line L of the main body 3 being maintained and with the required width size ℓ2 [=2X(ℓ1+ℓ3)] of the main body 3 being maintained. Thereafter, the center plate 360 is mounted with screws 351, 351 on the front face of the compartment reinforcing plate 350 mounted on the front face of the compartment wall 340 through the adiabatic material 390 for preventing the dew. At this time, the coupling portion 362 formed on the both the right, left end portions of the center plate 360 is engaged into the engagement groove 327 formed in the right side plate 323 and the left side plate 324 so as to be superposed onto the flange portion 326A on the front face side. The tapped holes 362A formed into the coupling portion 362 are brought into conformity to the tapped holes 326A1 formed in the superposed portion of the flange portion 362A of the front face side so as to fix the dressing plate 360 onto the outer shell through the engagement of the screws 380 with the tapped holes 262A, 326A1. Namely, the outer shell (here the right-side plate 323 and the left-side plate 324) are secured onto the compartment portion 340 secured onto the inner box 330 through the flange reinforcing plate 312, the compartment fixing plate 329 and the compartment reinforcing plate 350, and also, are secured onto the compartment portion 340 even through the center plate 360 and the compartment reinforcing plate 350 so that the whole main body 3 is strictly formed by the mutual operations. After the main body 3 has been formed in this manner, the vesicatory adiabatic material 310 filled into the space between the inner box 330 and the outer shell to complete the manufacturing operation of the refrigerator box. Fig. 9 shows another embodiment of the present invention. Namely, in order to improve the assembling property of the main body 3, the coupling portion 362 to be formed on the center plate 360 is only one end portion (in the present embodiment, right end portion) of the right side or the left side, with the other end portion being a butt type for the front face side flange portion 326A of the outer shell. Instead, the left end portion of the compartment reinforcing plate 350 is further extended so as to be superposed on the front face side flange portion 326A with the superposed portion K being engaged through the screws 391. By such construction as described hereinabove, the same effect as in the connection through the flange portion 326A of the respective front face side of the right side-plate 323 and the left-side plate 324, and the screws may be provided with the coupling portion 362 being formed on both the ends of the center plate 350. As described hereinabove, according to the refrigerator of the present embodiment, one on the rear portion side of two (lines) flange portions formed on the front side edge of the right-side plat and the left-side plate constituting the outer shell is supported by an approximately L-shaped (in section) long reinforcing plate, which is secured in its one side piece onto the right-side plate and the left-side plate, a compartment fixing plate with its tip end portion being projected into the box interior through the side plate portion of the inner box is mounted in a position corresponding to the compartment portion of the flange reinforcing plate, both the end portions of the fixing plate are integrally secured onto both the end portions of the compartment reinforcing plate with screws, etc., a coupling portion is formed on one end or both the end portions of the center plate, the overlapped portion between the coupling portion and the two (lines) flange portion formed on the right-side plate and the left-side plate are integrally secured with screws, etc. Therefore, the strength as the main body may be sufficiently maintained and also, the shape does not change even by the load burden through the connection and the opening, shutting of the door, by impacts during the packing and the transportation, so that the good appearance may be maintained. In the case of door being capable for opening/closing at the both sides, it is difficult to open or close the door smoothly in the condition of that the pitches between the left and right hinge pins 2A and 2B and between the arrangement grooves 7A and 7B do not be kept at constant, and the hinge pins of four positions at left and right and top and bottom do not be existed in a given relationship with each other, but by the employment of the construction of the present embodiment, it is easy to provide the door being opened or closed smoothly. Also, by the correct determination after the sufficient consideration of the forming position of each tapped hole provided in the tip end of the compartment fixing plate and the coupling portion of the compartment reinforcing plate, the right-side plate and the left-side plate are mounted on the inner box through the compartment fixing plate and the compartment reinforcing plate. Accordingly, the right-side plate and the left-side plate may divided equally in the width direction from the central line of the main body and simultaneously the adjustment of the width size required as the main body may be effected so that the size accuracy of the main body may be improved. Furthermore, as the size accuracy of the main body may be improved, the load applied on the jig for vesication which is used to fill the vesicatory, adiabatic material into the main body is reduced, the aging change of the vesication jig is extremely reduced. Therefore, the completion degree as the main body after the vesicatory material has been filled is also improved. Figs. 10 and 11 are respectively perspective dismantled views of a frame member for a refrigerator use in accordance with the first embodiment of the present invention. Fig. 12 is a front view showing the assembling condition of the frame members of the refrigerator door. Fig. 13 is a perspective dismantled view of the frame members for the refrigerator door use in a modified embodiment of the present invention. Fig. 14 is a front face view showing the assembling condition of the frame members. Fig. 15 is a perspective dismantled view showing the upper portion of the frame members of the refrigerator door in accordance with the other modified embodiment of the present invention. Fig. 16 is a sectional view showing the assembling condition in the upper portion of the frame members. In the present embodiment, the door 1 is constructed to provide a packing 430 for providing a seal of cooling between the door 1 and the main body 3 upon fixing the frame member 401 onto the internal plate 420 after the external plate 400 is fitted into the frame member 401, and a foamed thermal insulating material (not shown) is filled into a vacant space formed between the external plate 400 and the frame member 401. The door 1 may be also constructed to provide a packing 430 after a foamed thermal insulating material (not shown) is filled into a vacant space formed among the external plate 400, frame member 401 and internal plate 420. The frame member 401 is constructed to connect the sashes 402A, 402B together with the sashes 403A, 403B through the re-enforcement angle 404, as shown in Figs. 11 and 12. The reinforcing angle 404 is disposed in the horizontal direction and is composed of a flat plate portion 405 which is the same in the longitudinal-direction length as the sashes 403A, 403B and side plate portion 406 formed through the bending operation of both the ends of the flat plate portion 405. Accordingly, when the frame members 401 of the refrigerator door 1 are assembled, first the sash 403A is disposed on the outer side face of the flat plate portion 405 so that both the ends of the sash 403A may conform in position to the end portions of the flat plate portion 405 of the reinforcing angle 404, with the sash 403A being mutually secured onto the angle 404 with bolts 407 and the nuts 408. Then, one end portion of the sashes 402A, 402B are disposed on the side plate portion 406 on both the sides of the reinforcing angle 404 so as to be mutually secured. Thus, three sashes 403A, 402A, 402B are integrally secured with the use of one reinforcing angle 404. Furthermore, the other ends of the sashes 402A, 402B are disposed on the respective side plate portions of the reinforcing angle 404 with the sash 403B being secured on the given position of the flat plate portion 405. In this manner, two opposite two pairs of sashes 402A, 402B, 403A, 403B are integrally secured into the frame member 401 along the outer side shape of the reinforcing angle 404 each having the given size and the given shape. Accordingly, as it is able to manufacture the door of high rigid structure with excellent precision in dimension in a stable manner by the operation of simple assemblement and adjustment, it is easy to open or close the door smoothly from the left or right side. The modified embodiment of the present invention will be described hereinafter with reference to Fig. 13 and Fig. 14 about a case where a reinforcing angel 404A is used in one example of the engagement members with the whole being formed into the integral frame shape. The reinforcing angle 404A is ]-shaped , with all the angles being rectangular, the respective side length of opposite to pairs being equally formed into the given size between the respective upper, lower sashes 403A, 403B and the given size between the respective right, left sashes 402A, 402B. Two pairs of sashes 402A, 402B, 403A, 403B are integrally secured in the respective given positions or the four sides of the reinforcing angle 404A in order to constitute the frame member 401A of the refrigerator door 1. Accordingly, the frame member 401A constructed as described hereinabove is made rigider than the frame member 401 disclosed in the previous embodiment with the labors required during the assembling operation being reduced. Continuously, the other modified embodiment in accordance with the present invention is provided wherein the reinforcing angle 404 in the first embodiment is formed. As shown in, for example, Fig. 11 and Fig. 12, an opening/closing device 409 capable of opening, closing the refrigerator door from the optional right or left side is to be placed on the top face of the ]-shaped reinforcing angle 404B to be placed on the upper side. The different point between such reinforcing angel 404B as described hereinabove and the reinforcing angle 404 in the first embodiment is that the boss 410 is projected slightly higher upwardly from the top face of the flat plate portion 405B than the width of the sash 403B. At this time, a hole 411 through which the boss 410 may be inserted is formed in the sash 403A made of composite resin. In the frame member 401B of such refrigerator door 1, the sash 403D is placed on the top face of the flat plate portion 405B of the reinforcing angle 404B with the boss 410 being inserted through the hole 411 of the sash 403D. Then the opening/closing device 409 is placed on the top face of the sash 403D so that they are integrally secured with each other. Furthermore, the sashes 402A, 402B secured with the reinforcing angle 404 on the lower side is additionally provided integrally on the reinforcing angle 404B into the frame member 401B. Such frame member 401B as constructed as described hereinabove may be made much higher in the mounting size accuracy of the opening/closing device 409. As the opening/closing device 409 is secured in direct contact against the reinforcing angle 404B, it is possible for the frame member 401B to be made hard to receive the influences such as dedormation, etc. caused through the dispersion of the molding size of the sash 403B, the thermal expansion or the thermal contraction. In the refrigerator door 1 which can be opened, close from the optional right, left side as described hereinabove, it is necessary to form on the end portions of the respective sashes 403A, 403B, 403D the engagement groove 412 into which the hinge pines 2A,2B as the opening, shutting shaft for the door pass. In the above-disclosed embodiment, three sashes or more are integrally secured with use of one reinforcing angle in any case, the mutual combination portion among the sashes may be maintained with sufficient strength in spite of the formation of the engagement grooves 412, 413, 414. As described hereinabove, the present embodiment is a refrigerator door of approximately rectangular shape in front face, wherein the door may be opened, close from the optional right or left side, the frame members are composed of respectively opposite two pairs of sashes, the adjacent sash pair are composed of frame members secured through an engagement member, with three sashes or more being integrally secured with the use of one engagement member.
