As a result, the rotation angle of the door 11 is limited within the predetermined angle α. At this time, when the first roller 36 is retracted into the recess 38, the first roller 36 is guided by the end 40 a of the side plate 40, and comes to a position where it can roll along the side plate 40.
[0026]
As the second stage of opening the door 11, when the door 11 in the state of the two-dot chain line on the right side in FIG. 3 is pushed to the left along the rail 15 while holding the handle 22 (see FIG. 1), the slide member 13 Slide 15 along. FIG. 6 shows the state of the lever mechanism 17 in this state. The first roller 36 rolls along the side plate 40, and the first roller 36 is sandwiched between the side plate 40 and the inner wall 38 a of the recess 38. Therefore, the position of the lever 35 is fixed, and the position of the elongated hole 39 engaging with the second roller 37, that is, the rotation angle of the door 11, is also kept at the predetermined angle α. As shown in FIG. 3, the end of the slide member 13 hits a stopper 42 with a cushion mechanism, and the door 11 is completely opened from an opening (not shown) of the apparatus main body 2 to be in an open state.
[0027]
When closing the fully open door 11 in the state of the two-dot chain line at the left end in FIG. 3, holding the handle 22 (see FIG. 1) and pushing the door 11 to the right in the drawing, the slide member 13 moves along the rail 15. Slide to move. The end of the slide member 13 hits the stopper 41 with the cushion mechanism, and is in the state of the two-dot chain line on the right side of the drawing. Next, when the door 11 is pushed toward the opening of the apparatus main body by holding the handle 22 (see FIG. 1), the door 11 rotates around the shaft 25, and the hook 32 is hooked on the pin 31, so that the door 31 is locked. 11 is completely closed.
[0028]
The effects of the above-described embodiment will be described below.
(1) As a first stage when the door 11 is opened, the door 11 is opened by the restricted predetermined angle α by the hinge member 12 and the lever mechanism 17 constituting the restricting means. The predetermined angle α is preferably within 10 °, for example, 5 °. Therefore, the high temperature gas such as hot air and steam or the high temperature and high humidity gas leaks from the opening 3 of the apparatus main body 2 to the outside through a slight gap, thereby improving safety. In addition, since the door 11 does not open wide, the installation space in the front-rear direction of the apparatus main body 2 is reduced.
[0029]
(2) As a second stage when the door 11 is opened, the door 11 is slid by the slide member 13 and the rail 15. Therefore, the door 11 can be completely opened by a simple operation of pushing the door 11 sideways while holding the handle 22 (see FIG. 1).
[0030]
(3) When the door 11 is closed, the operation of sliding the door 11 toward the opening 3 and the operation of pushing the door 11 toward the opening 3 by the hinge member 12 are separated. The power to do so is minimal.
[0031]
(4) While the door 11 is slid, the state in which the door 11 is opened by the predetermined angle α is maintained by the lever mechanism 17 constituting the holding means. Can be slid.
(5) The locking and unlocking of the door 11 with respect to the apparatus main body 2 is performed when the door 11 is rotated with respect to the opening 3, so that the locking and unlocking operation becomes easy and the lock and unlocking is ensured. Done in
[0032]
The above-described embodiment can be modified and implemented as follows.
(1) The door 11 is not limited to the one that opens and closes left and right, but may be one that opens and closes vertically. When opening and closing vertically, the sliding members provided on the left and right of the door 11 are symmetrical left and right, and a counterbalance mechanism for easily performing vertical sliding is attached to the door 11. The hinge member is provided at one of the upper and lower ends of the door 11. A biasing spring in the opening direction can be provided to keep the door 11 slightly opened by the upper or lower hinge member. Further, a lever mechanism 17 that constitutes a restricting means and a holding means is also provided symmetrically with respect to the door 11.
[0033]
(2) When the door 11 is opened and closed to the left and right, a lever mechanism 17 which serves both as a limiting means and a holding means is preferable, but the limiting means and the holding means may be provided separately. For example, in FIG. 1, it is possible that the long hole 30 of the door support mechanism 18 is closed forward, and the pin 29 with the head hits the end of the long hole 30, and the rotation angle of the door 11 can be set to the predetermined angle α. In this case, the lever mechanism 17 can have only the function of the holding means. That is, the first roller 36 can be prevented from hitting the inner wall of the recess 38.
[0034]
(3) The restricting means is not limited to the lever mechanism 17, and various means can be adopted as long as they are provided between the slide member 13 and the door 11 and limit the separation distance between the two. As described above, the door support mechanism 18 can also be used as the restricting means.
[0035]
(4) The holding means is not limited to the lever mechanism 17, and various means can be employed as long as they are provided between the slide member 13 and the door 11 and maintain the separation between them. Instead of fixing the open state of the door 11 as in the above-described embodiment, the open state of the door 11 may be held by engaging means. For example, a recess may be provided in an appropriate position of the door 11, and when the door 11 is opened, a so-called ball plunger-type engagement means for urging a ball to be engaged with the recess may be provided in the lever 35 or the door support mechanism 18. it can.
[0036]
Inventions other than the claims described in the above-described embodiment include the following.
(1) A hinge member having a vertically arranged shaft that supports a door so that it can be opened and closed in a half-open manner with respect to the opening, and a rail disposed above the opening in a direction parallel to a surface of the opening. A sliding member that supports an upper side of the hinge member and slides along the rail; and a limit that is provided between the sliding member and the door and limits a rotation angle of the door by the hinge member within a predetermined angle. Means for a door of an environmental test apparatus. The opening and closing direction of the door is left and right, and the door sliding mechanism and the means for restricting the rotation angle of the door can be collectively arranged above the opening. A door device with a hinge function added in a sliding manner can be obtained simply by adding a restricting means for restricting the door device to a predetermined angle.
[0037]
(2) The restricting means is provided between the sliding member 13 that slides along the rail 15 and the door 11, and is provided so that when the door 11 reaches the predetermined angle, the lever 35 is provided so as to stick between them. It has. The pivot angle of the door can be easily and reliably limited by merely providing an arm that extends between the door and the slide member when the door is opened.
[0038]
(3) The holding means is such that a roller 37 provided on one arm of the lever 35 in the limiting means is engaged with a hole 39 which contacts the door 11 in any of the opening and closing directions, and the other arm of the lever 35 Is provided between the side plate 40 provided along the rail 15 and the slide member 13 so that the lever 35 is held while the door 11 is slid along the rail 15. It was done. The limiting means and the holding means are constituted by a common lever, and the structure is simplified.
[0039]
【The invention's effect】
According to the door device of the first aspect, the rotation angle when the door is opened by the hinge member is limited to a predetermined angle by the restricting means, and the high temperature gas or the high temperature gas such as hot air or steam from the main body of the environmental test device. Wet gas does not blow out to the front. Therefore, safety at the time of operating the door can be improved. Also, the door can be slid to move the door out of the opening, and when the door is closed, the door is slid toward the opening and then pushed into the opening to lock. Therefore, the operation of opening the door widely can be easily operated as in the case of a normal sliding door device. Further, unlike the case of using only the sliding door device, no inertial force is required when closing the door, so that the door can be easily opened and closed. Furthermore, the rotation angle when the door is opened can be limited to a small value, for example, within 10 °, so that the space in the front-rear direction when the door is opened and closed can be reduced, and the installation space for the environmental test apparatus can be reduced.
[0040]
According to the door device of claim 2, when the door is slid, the door can be held in a slightly open state, so that the door can be slid only by the operation of opening and pushing the door. Since the door does not swing in the rotation direction, the sliding movement operation can be easily performed.
