  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the oven 1 has an opening 19 on the front surface of the oven body 10, and a door 2 that opens and closes the opening 19 is pivotally supported on the oven body 10 by a shaft 3. Has been. Although the oven 1 is a business gas oven, the oven of the present invention is not limited to this, and includes a household gas oven and an electronic oven. In addition, although an oven is illustrated and described as an apparatus, the apparatus is not limited to the oven, and includes an opening such as a gas range or a microwave oven, a dishwasher, a rice cooker, a tabletop shelf, or the like. Is included.

  As shown in FIGS. 2 and 4, the shaft 3 has a pair of plate-like fixing members 4 extending downward from lower portions on both side ends of the inner surface 22 of the door 2, and a shaft is inserted into an insertion hole 41 provided in the fixing member 4. 3 is inserted and fixed by welding or the like. The fixing member 4 includes a base 47 that extends downward from the lower portions of both end portions of the inner surface 22 of the door 2 and an extending portion 48 that extends from the base 47 directly below the door 2. The insertion portion 41 is provided in the extending portion 48. By installing the shaft 3, the shaft 3 is positioned directly below the lower surface 23 of the door 2. Further, the gap 40 between the door 2 and the extended portion 48 eliminates the need to provide a notch in the front plate 55 by inserting a front plate 55 of the cover 5 described later when the door 2 is opened. Thus, the shaft 3 is installed outside the door 2.

  Note that when the front plate 55 is notched or a cover is not provided, the fixing member 4 is not provided with an extending portion that protrudes laterally from both side ends of the lower surface 23 of the door 2. In addition, it is not limited to a plate shape, and may be a shape such as a rod or a columnar body. It is preferable to install the shaft 3 so as to be positioned directly below the lower surface 23 of the door 2 in order to balance, prevent the shaft 3 from coming off from a support recess 111 described later, and the like.

  As shown in FIGS. 2, 4, 5, and the like, a plate-like support member 11 provided with a support recess 111 that opens upward is provided at the lower part of the oven body 10, and the support recess 111 is directly below the lower surface 23 of the door 2. It is fixed to be positioned. The shape of the support recess 111 is not particularly limited as long as the shaft 3 can be inserted from above and the shaft 3 can be rotatably supported, but the bottom surface has an arc shape corresponding to the shape of the shaft 3, and the diameter of the shaft 3 It is preferable to have a depth equal to or greater than for smooth rotation and reliable holding. Also, a pair of support members 11 are provided below both ends of the front opening 19 of the oven body 10 that opens and closes by the door 2, and both ends of the shaft 3 are inserted into the respective support recesses 111 from above, and installed. If the door 2 can be rotatably supported, the shape of the support member 11 is not limited to a plate shape, and the number of installations is not limited. Further, the position of the support recess 111 is appropriately changed and installed in accordance with the position of the shaft 3.

  Thus, the shaft 3 is fixed to the fixing member 4 extending downward from the door 2, and the shaft 3 is inserted from above into the support recess 111 that opens above the support member 11 provided in the oven body 10, The door 2 is installed in the oven body 10 so as to be rotatable about the shaft 3.

  As shown in FIG. 5, through holes 33 are provided at both ends of the shaft 3 and outside the fixing member 4, and a part of a clip 39 formed by bending a rod is inserted into the through hole 33. It is preferable to fix the clip 39 to the support member 11 so as to be able to be engaged with the support member 11 and prevent the shaft 3 from slipping laterally. Even if such a through-hole is provided, the diameter thereof is small and provided outside the fixing member 4, so that the strength of the shaft 3 is not affected and a strong shaft can be obtained.

  As shown in FIGS. 4 and 5, the bent upper end 611 of the connecting rod 61 is inserted into the connection hole 42 provided in the lower end of each of the pair of fixing members 4, specifically the lower end of the base 47. The lower end portion 612 of the connecting rod 61 that is bent is engaged with the recessed portion 60 that opens downward at one end of the rotatable rotating member 6 installed in the oven body 10, and rotates with the fixed member 4. The member 6 is connected.

  The rotating member 6 is a plate-shaped member having a U-shaped shape, and has a shape extending in the left-right downward direction with the bent portion 65 as a vertex, and a shaft hole 691 of a support bracket 69 provided below the door 2 of the oven body 10. The rotation shaft 68 supported by the first and second rotation shafts 68 is inserted into a hole (not shown) provided in the bent portion 65, and is supported so as to be rotatable about the rotation shaft 68. A connecting hole 64 is provided at the other end of the rotating member 6, and an end portion of the biasing member 7 is inserted and locked, and the rotating member 6 and the biasing member 7 are connected. Therefore, the pair of rotating members 6 are connected via the biasing member 7. The fixing member 4 is connected to the urging member 7 through the rotating member 6. The rotating member 6 and the urging member 7 are located below the shaft 3.

  The connection hole 42 may be moved from below to above when the door 2 is moved from the closed state to the open state, and is not necessarily provided at the lower end portion of the fixing member 4. Further, the connection hole 42, the recess 60, and the connection hole 64 are not holes or recesses, but can be engaged with the connection rod 61, the biasing member 7, the spring 71, or the tip of the turnbuckle 72. Alternatively, the shape of the hole can be selected as appropriate.

  The urging member 7 is a member that urges the door 2 to be held in a closed state and prevents the shaft 3 from coming out of the support recess 111, and is configured only by a stretchable elastic member such as a spring 71. However, as shown in FIG. 2, it is preferable to connect a stretchable elastic member such as a spring 71 and a length adjusting member such as a turnbuckle 72. With this configuration, it is easy to weaken, strengthen, or adjust the urging force of the spring 71 by adjusting the length adjusting member such as the turnbuckle 72 that can be easily adjusted in length. . The spring 71 is for tension.

  When the biasing member 7 is configured by connecting the spring 71 and the turnbuckle 72, the end portion of the spring 71 that is not connected to the turnbuckle 72 is inserted into the connecting hole 64 and locked in the one rotation member 6. The end of the turnbuckle 72 that is not connected to the spring 71 is inserted into the connecting hole 64 and locked to the other rotating member 6.

  Here, the operation when the door 2 is opened will be described. When the handle 25 is pulled forward and downward, the pair of fixing members 4 rotate around the shaft 3 and the pair of connecting rods 61 move upward. Then, the pair of rotating members 6 rotate around the rotating shaft 68 to pull the spring 71 and the turnbuckle 72 from both sides, and the spring 71 extends, whereby the tension of the spring 71 increases and the door 2 suddenly increases. The opening operation can be prevented and the closing operation can be facilitated by assisting the closing operation of the door 4. When the door 2 is fully opened, the gravity due to the weight of the door 2 is superior to the pulling force of the spring 71 and is not closed arbitrarily.

  Moreover, since the shaft 3 is always pulled downward by the urging member 7 through the fixing member 4 from the above-described configuration, it is possible to prevent the shaft 3 from coming off from the support recess 111.

  A removable cover 5 is installed below the door 2 of the oven body 10. The cover 5 is for concealing the visible shaft 3 installed in the lower part of the door 2, the spring 71, the turnbuckle 72, etc., and making the oven 1 excellent in design, as shown in FIG. The upper plate 53 extends from the upper end of the front plate 55 to the inside of the oven body 10, the lower plate 54 extends from the lower end of the front plate 55 in the same direction as the upper plate 53, and the side plate 56. It is fixed to the oven body 10 with screws 59 or the like. When the cover 5 is installed, the upper surface plate 53 is positioned above or in contact with or close to the shaft 3 above the support recess 111 and the shaft 3. With such a configuration, by installing the cover 5 on the oven body 10, it becomes possible for the upper surface plate 53 to regulate the upward movement of the shaft 3, and it becomes a locking member that locks the shaft 3. As described above, the biasing member 7, coupled with the fact that the shaft 3 is always pulled downward via the fixing member 4, makes it possible to more reliably hold the shaft 3.

  In addition, the upper plate 53 is not used as a locking member for holding the shaft 3, but is a locking member 51 formed of a plate having a locking recess 52 that opens downward or sideward inside the cover 5. It is good also as projecting inward of the oven main body 10. In such a configuration, by installing the cover 5 on the oven body 10, the shaft 3 can be inserted into the locking recess 52 and the upward movement of the shaft 3 can be restricted. Note that the locking member may have a linear rod-like or plate-like configuration in contact with or close to the shaft 3 above the shaft 3.

  Next, an example of a method for attaching the door 2 to the oven 10 will be described. First, both ends of the shaft 3 are inserted from above into a support recess 111 that opens above a pair of support members 11 provided below both ends of the front opening of the oven body 10, and the shafts are inserted into the support members 11 and 11. 3 is locked and is supported rotatably. Next, the connecting rod 61 connected via the spring 71 or the turnbuckle 72 and the support bracket 69 is inserted and locked in the connection hole 42 of the fixing member 4 extending downward from both side ends of the door 2. In this case, if the turnbuckle 72 is loosened and tightened after the attachment is completed, the attachment becomes easier.

  Further, a cover 5 is installed below the door 2. At this time, the upper surface plate 53 is positioned above or in contact with the shaft 3 above the support recess 111 and the shaft 3, and serves as a locking member that locks the shaft 3. In addition, when the separate locking member 51 is provided in the cover 5, the shaft 3 is inserted and installed in the locking recess 52.

  When removing the door 2, the cover 5 is removed, and the locking of the locking member to the shaft 3 is released. Then, the connection between the connecting rod 61 and the fixing member 4 or the support bracket 69 is released. At this time, the turnbuckle 72 may be loosened. Finally, the door 2 is lifted upward, the shaft 3 is removed from the support recess 111, and the door 2 is removed.
