DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picture easel.

[0002]

2. Description of the Related Art Conventionally, as an easel for painting of this kind,
A flat frame formed by connecting the upper and lower ends of a pair of left and right front legs by an upper crosspiece and a lower crosspiece, and rotatably around a horizontal axis between the pair of front legs at a position below the upper ridge. A rear leg having an upper end connected to the attached rotating member, and a mounting table detachably attached to a front surface of the pair of front legs, wherein the rear leg is folded between the pair of front legs when not in use. What can be accommodated and stored has been known for a long time (see, for example, Japanese Utility Model Laid-Open No. 63-202343 and Japanese Utility Model Laid-Open No. 2-121839).

[0003]

The easel for painting as described above has a simple structure and is convenient for storage and accommodation. However, the easel for painting is used in the assembled position by rotating the rear leg backward. There was a problem that the supporting state of the legs was unstable and the legs were easily fallen.

Accordingly, an object of the present invention is to provide a painting easel in which the support state of the rear leg in a use position is stabilized, and the operation of the rear leg can be performed by one-touch operation, so that it is convenient to use and handle. And

[0005]

In order to achieve the above object, the present invention provides a flat frame formed by connecting upper and lower ends of a pair of left and right front legs by an upper beam and a lower beam. A rear leg having an upper end connected to a rotating member rotatably mounted around a horizontal axis between the pair of front legs at a position below the rung, and a mounting detachably mounted on a front surface of the pair of front legs. In a painting easel having a table, the rear leg has a pair of support rods, and upper ends of the pair of support rods are respectively pivotally connected to intermediate positions of the pair of front legs, and lower ends thereof are respectively A spring means is provided on the rear leg, which is pivotally connected to both ends of a support pin slidably provided in a vertical direction at a lower end portion of the rear leg, and biases the support pin upward. When the rear leg is in the use position rotated backward, A spring means acts to urge the pair of support rods rearward, while the rear leg and the pair of support rods are accommodated between the pair of front legs when the rear leg is in an unused position. It is configured to be.

[0006]

According to the above construction, when the rear leg is slightly rotated rearward from the folded unused position, the pair of support rods are urged rearward by the action of the spring means, and the rear leg is forcibly forced. It can be turned to the use position at a stretch. Further, when in the use position, the lower end portion of the rear leg is connected to the pair of front legs via the pair of support rods, so that a stable supporting state is achieved.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view and a side view of a painting easel according to the present invention in an unused state. The easel for painting 1 has a pair of left and right front legs 2, 2 arranged in a U-shape at a predetermined interval, and upper and lower ends of both front legs 2, 2 are formed by an upper ridge 3 and a lower ridge 4. A planar frame 5 is formed by coupling. A rotating member 6 to which a rear leg 8 is attached is provided below the upper ridge 3. The pivoting member 6 is rotatably supported about a horizontal axis by fitting pivoting pins 7 projecting from both ends into mounting holes (not shown) provided inside the front legs 2. The upper end of the rear leg 8 is fixedly connected to a central portion of the rotating member 6. The rear leg 8 is rotatable rearward from the non-use position shown in FIG. 1 to the use position shown in FIG. 2 with the rotation member 6 as a fulcrum. The engagement step 8a is formed by cutting about 1/2 of the above. Then, in the non-use position, the engaging step 8a is engaged with the concave portion 9 provided at the central portion of the lower support 4, so that the rear leg 8 is provided as shown in FIGS.
Protrudes from frame 5 and does not stretch
It is designed to be accommodated in the space between the two. Although not shown, it is desirable to provide a stopper for locking and holding the engaging step 8a to the lower ledge 4 when the rear leg 8 is at the unused position shown in FIG.

The lower end of the rear leg 8 has a pair of support rods 10, 10
Are connected to and supported by both front legs 2, 2. Each support rod 10 has an upper end pivotally connected to an inner portion of the front leg 2 at an intermediate position via a pivot pin 11, and a lower end of the rear leg 8.
Are pivotally connected to both ends of a support pin 12 which is disposed to penetrate the lower end portion in the lateral direction. On the other hand, a concave groove 13 extending in the longitudinal direction is provided inside the lower end portion of the rear leg 8, and is supported by long holes 15, 15 extending in the longitudinal direction provided on opposite side walls 14, 14 of the concave groove 13. The pin 12 penetrates and is slidably mounted in the vertical direction along the long holes 15. A tension spring 16 is housed in the groove 13, and the upper end thereof is fixed to the rear leg 8 by a stopper 17,
The lower end is connected to a support pin 12, and the tension spring 1
6, the support pin 12 is urged upward by itself. When the rear leg 8 is folded as shown in FIG. 1 and accommodated between the front legs 2, 2, the support rods 10, 10 are also accommodated in the space between the front legs 2, 2, as shown in FIG. As shown in FIG. 3), the frame 5 is entirely contained in the frame 5.

On the other hand, holes 18 are provided in the front legs 2, 2 at predetermined intervals in the vertical direction, and a canvas mounting table 20 is supported by a plug member 19 inserted into the hole 18 at a predetermined position. It has become so.

When the rear leg 8 is slightly rotated rearward from the non-use position shown in FIG. 1 in the painting easel 1 having the above configuration, the two supporting rods 10 and 10 is urged rearward, and in conjunction with this, the rear leg 8 is forcibly rotated so as to jump to the use position shown in FIG. Therefore, it is set to the use position by one-touch operation. In addition, in the use position, the lower end of the rear leg 8 is connected to the front legs 2, 2 via the support rods 10, 10, which are in a state of being urged rearward. It is stable.

[0012]

As described above, the easel for painting of the present invention can be set to the use position by rotating the rear leg backward by one-touch operation. Moreover, when in the use position, the lower end portion of the rear leg is connected to the pair of front legs via the pair of support rods, so the rigidity of the rear leg in the supporting state is large, and a very stable supporting state is achieved. can get. Further, when in the non-use position, the rear leg and the pair of support rods are accommodated in a space between the pair of front legs, which is convenient for storage and accommodation without being overpowered.
