A door having a front outer edge rotatably supported near one end of the groom window and a hook slider for locking the door near the other end of the groom window; A fixing member attached to the hood near the other end of the first member, and slidably attached to the fixing member to be urged by the first spring from the retracted position toward the locked position, and to the elastic force of the first spring. A movable member having a push button surface that is moved to the retracted position by receiving a pressing force, and a lock surface that locks the door by engaging with the front outer edge of the door at the lock position; A stop member for holding the movable member at the retracted position when the push button surface is pressed, and releasing the holding at the retracted position when the movable member comes into contact with the door.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. 4 to 7 are partial schematic sectional views of an incubator according to one embodiment of the present invention as viewed from the front side.
In FIGS. 5 to 7, members corresponding to the members described in FIG. 1 are denoted by the same reference numerals.

In FIG. 4, a substantially rectangular parallelepiped main body 1 of an incubator is shown.
2 incorporates equipment such as air conditioning. A transparent nursery room 14 is mounted on the main body 12, and a partition plate (not shown) is detachably mounted between the main body 12 and the nursery room 14. The nursery room 14 has four sides and a ceiling formed of a transparent hood 16 made of acrylic resin or the like, and is hinged to the rear body 12 so as to be rotatable, for example, 60 degrees for cleaning.

The nursery room 14 is provided with a bed (not shown) on which the child is to be laid, and a lifting device (not shown) in which the right and left heights of the bed can be individually adjusted by a handle 18. I have. This elevating device is detachably screwed onto a partition plate, and a bed bed is detachably mounted on the elevating device. Therefore, the removed lifting device can be easily cleaned and disinfected.

Further, a transparent door 30 of a care window 20, which is opened and closed when a nurse accesses a child or attaches a medical device, is attached to a front surface of the hood 16 by a hinge (not shown) or the like. I have.

FIG. 5 is a partial schematic cross-sectional view of the maintenance window 20 when the door 30 of the maintenance window 20 is open and the hook slider 10 is in a standby state. FIG. 6 is a partial schematic cross-sectional view of the care window 20 in a state immediately before the stop member of the hook slider 10 is pressed by the door. FIG. 7 is a partial schematic cross-sectional view of the care window 20 in which the hook slider 10 is locked.

In FIGS. 5 to 7, the hook slider 10 is formed near the door 30 of the care window 20 formed in the hood 16 of the incubator. The care window 20 of the hood 16 overlaps with the door 30 when closed, and
Is provided with a sealing material 31 made of silicone rubber for sealing.

That is, the door 30 is rotatably supported by the hinge 33 on the hood 16 near one end 32 of the groom window 20 and has a front outer edge 34 inclined at least at the other end from the transparent door surface. . The hood 16 near the other end 38 of the care window 20 is provided with a hook slider 10 that engages with the front outer edge 34 to lock the door 30.

The hook slider 10 is provided with a maintenance window 20.
And a movable member 42 slidably mounted on the slope of the fixed member 40. That is, the fixing member 4
The inclined surface formed on the front surface of the hood 16 converts a pressing force orthogonal to the hood 16 into a force that reciprocates substantially parallel to the surface of the hood 16.

The movable member 42 is urged by the first spring 44 from the retracted position (the position shown in FIG. 5) toward the locked position. According to the present invention, the movable member 42 is held at the retracted position by the stop member 52. It has become.

That is, since the push button surface 46 is usually covered with a part such as a finger in order to prevent bacterial contamination in the treatment of a baby, the push button surface 46 receives a pressing force by a part other than the finger of a nurse, for example. The movable member 42 resists the elastic force of the first spring 44.
To the retracted position. At this time, the stop member 5
As shown in FIG. 5, the second projection 54 penetrates into the gap 53 formed between the fixed member 40 and the movable member 42 at the retracted position by the urging force of the second spring 56, and Hold in the retracted position.

Accordingly, the stop member 52 is urged by the second spring 56 in the fixing member 40 in a direction perpendicular to the surface of the hood 16 and is attached to the rear outer edge 36 of the door 30 which is not necessarily inclined. A second protrusion 58 is provided that can come into contact with the movable member 42 and release the holding state. FIG.
Shows the state immediately before the second protrusion 58 comes into contact with the rear outer edge 36 of the door 30 to release the holding state of the movable member 42.

According to the present invention, the surface corresponding to the conventional push-open slope 48 engages the rear outer edge 36 of the door 30 against the elastic force of the first spring 44 to move the movable member 42 to the retracted position. Since there is no need to move, it can be omitted. Also,
FIG. 7 shows the lock surface 50 of the movable member 42 that locks the door 30 by engaging with the front outer edge 34 of the door 30 in the locked position. In this case, the stop member 52 does not allow the protrusion 54 to enter the narrow gap 53 formed between the fixed member 40 and the movable member 42, and the second protrusion 58 is slightly located at the rear outer edge 36 of the door 30. It has been pushed in.

[0020]

According to the hook slider of the incubator according to the present invention, when the door 30 is closed, the rear outer edge 36 of the door 30 is closed.
Does not come into contact with the push-open slope 48 as in the past, but only contacts the second projection of the stop member, and then moves in the locking direction. A highly reliable hook slider that does not easily open even when a force is applied can be provided.

The force required to close the door 30 is:
This is substantially equivalent to the elastic force for urging the second protrusion of the stop member, and therefore has the advantage that the noise is less than half that of the conventional one and the noise at the time of closing is considerably reduced compared to the conventional one.
