Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a stay device for holding a door in an open position.

[Summary of the idea]

In the door stay device, the present invention fixes a guide metal fitting having a long L-shaped guide groove, a hole, and a step to the case side, and connects this guide metal fitting and the door with an arm with a bent tip. This allows the door to be held open and to be easily removed.

[Conventional technology]

FIG. 5 is a perspective view showing an example of a conventional stay device. In the same figure, 1 is the case of the device (for example, a wall-mounted notification device, etc.), and 2 is the case 1, which is a hinge, etc.
12 is a slider, 3 is a pin, 14 is a screw, 15 is a groove made in the slider 12, and 16 is a metal fitting fixed to the case 1. One end of the slider 12 is rotatably attached to the door 2 by a screw 14, and a pin 13 is placed in the groove 15 of the slider 12 on a metal fitting 16 of the case 1.
enters and slides in response to opening and closing of door 2. Since the other end of the slider 12, and therefore the tip of the groove 15, is slightly bent, when the door 2 is opened to a certain angle, the pin 13 enters this bent part, and the door 2 is opened as shown in FIG. is held open. Therefore, when inspecting the equipment inside the case for maintenance or the like, the door 2 does not get in the way and is convenient.

[Problem that the invention attempts to solve]

However, when installing equipment, etc., if the door remains open, it will interfere with wiring and installation work, so it may be better to remove the door.
However, the conventional device described above has a drawback that the door 2 cannot be removed unless the pin 13 or screw 14 is removed. Furthermore, if the pin 13 or screw 14 is removed, there is a risk of losing them, and the pin 13 is structurally difficult to remove.
Moreover, it requires metal fittings for attaching the screws 14, and also has the drawback that it takes time and effort to tighten the screws.

[Means for solving problems]

In this invention, a guide fitting with a long L-shaped guide groove, a hole, and a step is attached to the case 1, and a round bar arm with one end bent and the other end rotatably attached to the door 2 is used to connect the guide fitting and the door. I made it concatenated.

[Effect]

With the above configuration, when the door is open, the hook portion of the arm enters the hook groove and hole of the guide groove and is held in that state. Furthermore, the door can be easily removed by removing the hook portion of the arm from the hook groove of the guide groove.

〔Example〕

Fig. 1 is a perspective view of the embodiment of the present invention showing the door in an open state, Fig. 2 is a perspective view of the arm shown in Fig. 1, Fig. 3 is a perspective view of the guide fitting shown in Fig. 1, and Fig. 4 is a perspective view of the arm shown in Fig. 1. FIG. 2 is a cross-sectional view taken along line A-A in FIG. 1; In these figures, 1 is a case, 2 is a door, 3 is an arm, 4 is a guide metal fitting, 5 is a support metal fitting, 6 is a guide groove, and 7 is a groove 6
, 8 is a hole, 9 is a hook portion of arm 3, 10 is a U-shaped bent portion of arm 3, and 11 is a stepped portion. The arm 3 has a hook portion 9 with one end bent in a substantially right angle direction (L-shape) and a bent portion 10 with the other end bent into a U-shape, and is made of a round bar. The guide fitting 4 is a metal fitting having a U-shaped cross section, has a guide groove 6 along the longitudinal direction on one of the opposing side surfaces, and is attached in a direction perpendicular to the case opening. One end of the guide groove 6 on the case opening side forms a hook groove 7 bent downward at right angles, and a hole 8 is provided on the bottom surface of the guide fitting 4 at a position corresponding to the hook groove 7. The stepped portion 11 is the hole 8
This part is provided on the bottom surface of the guide fitting 4 in order to raise the part above the bottom surface of the case 1.

The U-shaped bent portion 10 of the arm 3 is inserted into a hole in a support fitting 5 fixed to the door, and is held rotatably. The hook portion 9 of the arm 3 is inserted into the guide groove 6 of the guide fitting 4 through the hook groove 7. Arm 3 is door 2
It slides along the guide groove 6 according to the opening and closing of the guide groove 6. The guide fitting 4 is fixed so that the hook groove 7 of the guide groove is on the front side. When the door 2 is opened to a certain angle, the hook 9 of the arm 3 falls into the hook groove 7 of the guide groove under its own weight, and the end of the hook 9 falls into the hole 8 (or it may be pushed in by hand). ), the door 2 is fixed in that position. FIG. 1 shows this situation. Note that since the hole 8 is raised above the surface of the case 1 by the stepped portion 11 provided on the bottom of the guide fitting 4, the end surface of the hook portion 9 of the arm is aligned with the hole 8.
It doesn't come off easily.

When closing the door 2, the hook 9 of the arm 3 is lifted, the end thereof is removed from the hole 8, and the hook 9 of the arm 3 is inserted into the straight portion of the guide groove 6. door 2
When the arm 3 is closed, the arm 3 is pushed and moves to the opposite side of the guide groove 6 as shown in FIG. When the door 2 is to be removed, the door 2 is opened to the state shown in FIG. The other end of arm 3 is U
Since the bent portion 10 is inserted into the hole of the support fitting 5, it cannot be easily removed.

Note that the guide fitting 4 has an L-shaped cross section as well as □
It can also be in the shape of a letter. Further, the U-shaped bent portion 10 of the arm 3 may have another shape as long as it can be rotatably attached to the door.

[Effect of idea]

As explained above, according to the present invention, the door 2 can be easily removed by simply pulling out the hook part 9 of the arm 3 from the hook groove 7 of the guide fitting 4, and even after removing the door 2, the arm can be attached to the door. It can be prevented from easily coming off, and even if it does come off, it is not as small as a pin or screw, so there is no risk of losing it. Also, the assembly process is easy because there are no screws or other parts to tighten.
