五、發明說明（1) [發明所屬之技術領域] 本發明係關於一種用以開閉例如業務用電冰箱或低溫陳列箱等儲藏庫之機械室等的門裝置者。 [以往之技術] 以往設置於旅館或餐廉等之厨房的業務用電冰箱等之儲藏庫，係例如日本實公平2-5351號^ ^Lf^5D297〇Q> 示，以轉動自如之對開兩扇門型之門開閉自如地關閉在前面開口之隔熱箱艘之該開口，同時機械室之前面係以枢轴支持一邊而成為轉動自如之門扇開閉自如地關閉。安裝於以往之此種儲藏庫之機械室前面的門之上部较鏈構件，係在安裝於儲藏庫之隔熱箱體之前面上部的頂台 $ 1強_板龙成IB孔，在該將該鉸鍵構件之其中一方之圓柱部嵌合於該圓孔而安裝，並將該鉸鏈構件之另一方之圓柱部插入於門之圓孔，而惠二Q1L鼓鏈構# 一耜蔣門枢裝成轉自如之狀態。 [發明欲解決之課題] 由於以往之鉸鏈構件係如上述在頂台面增強板之圆孔插入圓柱部而固定，因此，由於門之轉動鉸鏈構件對於圓 ^會轉動’而由於歪斜或轉動應力而產生該鉸鏈構件會損壞之問題。另外也有由於鉸鏈構件之歪斜或是轉動應力之關係使門脫落之問題。本發明係為了解決此種以往之技術上之課題而創作者 ’而其目的係在提供一種在開閉門時防患門之脫落於未然而可實現順暢地開閉門的門裝置。V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a door device for opening and closing a mechanical room of a storage room such as a business refrigerator or a low-temperature display case. [Historic technology] The storage compartments for business refrigerators and other appliances that were previously installed in hotels, kitchens, etc. are, for example, Japan Fair Fair 2-5351 ^^ Lf ^ 5D297〇Q > The door of the fan-type door can be opened and closed to close the opening of the heat-insulating box ship opened at the front, and at the same time, the front face of the machine room is pivoted to support one side, so that the door can be opened and closed freely. The upper part of the door, which is installed in the front of the mechanical room of this kind of storage in the past, is a chain member, which is installed on the top of the front surface of the insulated box installed in the storage. The cylindrical part of one of the hinge members is fitted into the round hole for installation, and the other cylindrical part of the hinge member is inserted into the round hole of the door, and Hui Er Q1L drum chain structure # 一耜蒋门枢Pretend to turn freely. [Problems to be Solved by the Invention] Since the conventional hinge member is fixed by inserting a cylindrical portion into the circular hole of the reinforcing plate of the top table as described above, the hinge member of the door will rotate with respect to the circle because of the rotation of the door, and it will be subject to skew or rotational stress This causes a problem that the hinge member is damaged. In addition, the door may fall off due to the skew of the hinge member or the relationship of the rotational stress. The present invention was created by the present invention in order to solve such a conventional technical problem, and its object is to provide a door device that prevents the door from falling off when the door is opened and closed and can smoothly open and close the door.

Description of the invention (2) [Means for solving the problem] The door device of the present invention is characterized by having: a square hole formed in the g plate; and a shaped end 4 ^ $! ^ * A hinge member composed of a cylindrical or cylindrical second end at one end; and a door; and a fastening hole formed in the door, and the first end portion of the hinge member is fitted to the side of the mounting plate Hole, the second end is rotatably inserted into the fastening hole of the door. According to the present invention, it is composed of: a square hole formed in the mounted plate; a square pillar or square tube-shaped first end portion formed on one end; and a cylindrical or cylindrical second end portion formed on the other end. A hinge member; and a door; and a buckle hole formed in the door to constitute a door device; a first end portion of the hinge member is fitted into a quilt hole, and a second soil jgp. The buckle hole to be fastened; therefore, the stress applied to the hinge member when the door is rotated is the sides of the first end portion. In this way, the incorrect situation that the hinge member rotates, or is skewed, or damaged due to the stress due to the opening and closing of the door, and prevents the door from falling off due to the rotation to achieve a smooth door opening and closing can be solved. . The door device according to the second aspect of the present invention is a device in which the above-mentioned device is formed with a flexible anti-dropping protrusion on the side surface of the first end portion. According to the invention in the scope of patent application No. 2, since in addition to the above-mentioned structure, a flexible anti-dropping protrusion is formed on the side of the first end portion, it can prevent the stress caused by the rotation of the door, It is an inconvenience that the first end portion is pulled out from the square hole and the hinge member is detached. In addition, since the protrusion is flexible, the operation of inserting and fitting the first end portion into the square hole can be performed smoothly.

The first end portion 41 has a size approximately equal to the inside dimension of the square hole 38 formed on the top mesa reinforcement plate 30, and the second end portion 42 is slightly larger than the fastening hole 39 of the panel 27 of the machine room I . In the above configuration, the first end portion 41 of the hinge member 36 is inserted into the household hole 38 of the platform reinforcing plate 30, and the protrusions 45 and 45 formed on the hinge member 36 are fastened to the upper side of the square hole 38. In addition, the flanges 44 and 44 are pressed below the top deck reinforcing plate 30, whereby the hinge member 36 is mounted on the top deck reinforcing plate 30 without falling off. Furthermore, the fastening hole 39 of the machine room panel 27 is rotatably inserted into the second end portion 42 of the hinge member 36 from below, and the upper portion of the machine room panel 27 is pivotally mounted in a freely rotatable manner. Also, the same left-hand side of the bottom of the machine room panel 27 corresponding to the bottom of the fastening hole 39 is formed with the same fastening hole not shown, and the hinge member 36 installed on the front left side of the front of the machine room 24 is the same. The hinge member is inserted into the fastening hole, whereby the upper and lower parts of the machine room panel 27 are pivotally mounted in a state of free rotation. [In the above configuration, when the machine room panel 27 is opened and closed (rotated), a stress that rotates the panel 27 is applied to the hinge member 36, but the stress is dispersed around the first end portion 41. As a result, the opening and closing of the machine room panel 27 is eliminated,

Description of the invention (6) It is inappropriate to rotate the hinge member 36 with respect to the top plate reinforcing plate 30, to skew it, or to damage it due to the stress, and prevent the mechanical room panel 27 from falling off in advance, The smooth opening and closing of the machine room panel 27 can be realized. Since the detachable protrusion 45 having flexibility is formed on the side surface of the first end portion 41, it is possible to more surely prevent the first end portion 41 from passing through the square hole 38 due to the stress caused by the rotation of the machine room panel 27. It is unsuitable to be pulled out or fall off from the chain member 36. In addition, since the protrusion 45 is flexible, the operation of inserting and fitting the first end portion 41 into the square hole 38 can be easily performed, and the installation of the cunning chain member 36 is not obstructed. In the embodiment, the first end portion 41 is formed into a square tube shaft shape, but a square column shape may be used. At the same time, although the second end has a bottomed circle ， p, m column shape may be used. [Effects of the Invention] As described in detail above, the present invention is provided with a square hole formed in the mounted plate, a square pillar or square tube-shaped first end formed at one end, and a cylinder or cylinder formed at the other end. A hinge member constituted by the second end portion, a door, and a fastening hole formed in the door; the first end portion of the hinge hinge member is fitted into a square hole of the mounted plate, and the second The ends are rotatably mated: the above-mentioned fastening holes of η, for this reason, the stress applied to the hinge member when the cardia is rotated is divided into the sides of the first end. The skewed opening and closing, the hinge member is inappropriate for the mounting plate to rotate, skew or be damaged due to the stress, and the resulting fall-off can be prevented beforehand, and a smooth door opening and closing action can be realized.
