DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stay for connecting a lid and a door to a fixed frame so as to be openable and closable.

[0002]

2. Description of the Related Art A hinge is well known as a means for connecting a lid or the like to a fixed frame so that it can be opened and closed.

[0003]

Depending on what is contained in the fixed frame, it may be preferable to move the fixed frame away from the fixed frame to some extent when the lid connected to the fixed frame is opened. For example, in the case of relatively small outdoor switch boxes used for street lights and other devices, even if there is no problem when operating the switch, the lid may be opened widely when inspecting and repairing the internal mechanism, or the lid may be closed. You may want to remove it from the main body so that the lid is out of the way. However, it will be obvious that removing and re-attaching the lid is a hassle.

[0004] It is an object of the present invention to provide a stay which can release the lid connected to the fixed frame relatively far from the fixed frame when the lid is opened.

[0005]

In order to solve the above-mentioned problems, the present invention is based on the premise that a fixed frame and a lid are interposed between the fixed frame and the lid. A stay comprising a pair of arms capable of integrally holding the lid on a lower portion of the fixed frame when the cover is pivoted open.

On this assumption, the present invention is characterized in that one of the arms (first arm) is pivotally attached to the inner surface of the fixed frame via a shaft member (first shaft member). A portion to be attached to the first shaft member is formed at the inner end of the arm, and the other of the arms (the second arm) is rotatable on the inner surface of the lid via a shaft member (the second shaft member). An attachment portion to the second shaft member is formed at an inner end of the arm so that the arm can be attached,
The first and second arms are rotatably connected via a shaft member (third shaft member) at an outer end which is an end opposite to the inner end of the first and second arms. Extends to the side of the second arm, when the lid is open,
Wherein the contact site capable from the front on the front portion of the fixed frame is formed, in.

In a preferred embodiment of the present invention, the first and second arms pivot relative to each other about the third shaft member at a portion of the outer end of the first arm outside the third shaft member. In this case, a stopper portion is formed which can abut the side edge of the second arm from the front in the turning direction to stop the turning.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the stay according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a switch box 2 in which a stay 1 is used. The box 2 includes a box main body 3 fixed to a wall surface or the like, a lid 4, and a pair of left and right stays 1 interposed between the main body 3 and the lid 4. The box 2 contains switches and the like, but their illustration is omitted.

The main body 3 is a cube or a rectangular parallelepiped,
A front opening 5, a back plate 9, a top wall 6 forming four circumferences,
It has a bottom wall 7 and a pair of side walls 8, a flange 12 is formed along the inner periphery of the opening 5, and a cushion pad 15 is attached to the front surface of the flange 12.

The lid 4 is opened by moving so as to pivot downward from above, and has a front plate 13, a top wall 16 forming four turns, a bottom wall 17, and a pair of side walls 18.

The stay 1 has a plate-shaped main body arm 21 and a lid arm 22. The main body arm 21 has an inner end 23 inside the main body 1, and has a main body 3 via a first shaft member 24. Is rotatably connected to a bearing portion 28 formed on the bottom surface 7 of the main body. The lid arm 22 has an inner end 26 inside the lid 4 and is rotatably connected to a bearing 29 formed on the front plate 13 of the lid 4 via a second shaft member 27. The main body arm 21 and the lid arm 22 have respective outer end portions 31 and 32.
Are rotatably connected to each other via a third shaft member 33. The arms 21 and 22 can pivot about the third shaft member 33 to open and close in an inverted V-shape. However, when the arms 21 and 22 are opened at a required angle, the main body arm 21 has a stopper portion 34 formed by bending a portion ahead of the third shaft member 33 substantially at right angles to the plate surface of the arm 21. The cover arm 22 can be engaged with the cover arm 22 from the front in the turning direction, and the turning of the cover arm 22 can be stopped. The first to third shaft members 24, 27, and 33 have E-
A ring 35 is attached.

In FIG. 1, the lid arm 22 is
2 has a laterally extending portion 36 extending parallel to the plate surface, and a portion 37 formed by bending the distal end portion of the extending portion 36 at a right angle is applied to the front surface of the flange 12 of the main body 3 from the front. In contact. With this contact, the main body arm 21 extending outside the main body 3 and the lid arm 22 located outside the main body 3 are in a state of being stationary with respect to the main body 3.
The lid 4 pivots about the second pivot shaft 27 in the direction of arrow P due to its weight. At this time, the edge 38 of the bottom wall 17 abuts against the side edge of the lid arm 22 from below, and the pivot stops. I do. The lid 4 connected to the main body 3 via the arms 21 and 22 can be separated from the main body 3 by extending the stay 1 while increasing the open angle between the arms 21 and 22. However, when the part 37 is in contact with the main body 3 and the stay 1 and the lid 4 are stationary as shown in the figure, the lid 4 is separated from the main body 3 by a distance W.

When the lid 4 opened in FIG. 1 is lifted in the direction of arrow Q, the part 37 of the lid arm 22 is separated from the flange 12 of the main body 3 and the side edge of the arm 22 is
1 abuts against the stopper portion 34 from below, and the main body arm 2
1 can be turned around the first shaft member 24 in the direction of arrow R, and the main body arm 21 can be housed inside the main body 3. The closed lid 4 is locked to the main body 3 via a locking member (not shown) attached to the lid.

FIG. 2 shows the stay 1 when the lid 4 is closed.
FIG. The main body arm 21 and the lid arm 22 that are opened in a V-shape approach each other while reducing the opening angle, and the main body arm 21 is housed inside the main body 3.
Extends from the inside of the lid 4, and the outer end 32 and the part 37 are located inside the main body 3. When the lid 4 is closed, the edges of the peripheral walls 16 to 18 are in contact with the pads 15 of the main body 3.

When the stays 1 are used as a pair as shown in FIG. 1, the stays 1 may have the same shape or may be symmetrical on the left and right as illustrated. The stopper portion 34 of the main body arm 21 has an opening angle between the main body arm 21 and the lid arm 22 of, for example, 100 to 1.
To act on the lid arm 22 when it reaches 10 °,
Its position can be determined. Site 3 of lid arm 22
7 is preferably formed by bending an extended portion of a plate-shaped arm as shown in the figure so as to be able to abut on the main body 3 in a large area. The portion 37 may be brought into contact with the main body 3 without being bent.

[0017]

According to the stay of the present invention, the fixed frame and the lid can be opened and closed via the first arm and the second arm which open in a V-shape. If the first and second arms are extended long so that the opening angle of the V-shape becomes large when the lid is opened while pivoting downward, when the lid is far away from the fixed frame and the inside of the fixed frame is operated, The lid does not get in the way.

The second arm is formed with a portion capable of holding the V-shaped first and second arms, which are in contact with the fixed frame when the lid is opened, to keep the first and second arms stationary. The lid can also remain stationary with respect to the fixed frame.
