Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as an easel for painting of this kind,
It has a pair of left and right front legs provided with a plurality of holes at predetermined intervals in the vertical direction, and a pair of plug members inserted into the holes at the left and right symmetrical positions of the pair of front legs support the mounting table. The ones that have been made have been known since ancient times.

[0003]

However, in the conventional easel, the supporting state of the mounting table by the plug member is unstable, and there is a risk of rattling or falling off.

Therefore, an object of the present invention is to provide an easel for painting in which the supporting state of the mounting table is stable and which does not rattle or fall off.

[0005]

In order to achieve the above object, the present invention has a pair of left and right front legs provided with a plurality of holes at predetermined intervals in the vertical direction. In a painting easel that supports a mounting table with a pair of plug members inserted into the holes at the symmetrical positions, a V groove having a downwardly sloping inclined surface is provided along at least the front wall surface of the mounting table, while An engaging protrusion having a V-shaped recess that engages with the bottom surface of the mounting table and the inclined surface is provided at one end of the stopper member, and a wedge hole is provided at the other end, and the wedge is further provided. It is characterized by including a wedge piece fitted in the hole.

[0006]

With the above structure, when the wedge pieces of the plug members are inserted into the wedge holes of the plug members inserted into the holes at the predetermined positions of the front legs, the plug members are inserted into the wedge holes of the plug members. Are pulled toward the front leg side, and the V-shaped concave portion of the locking projection engages with the inclined surface of the mounting table described above, and the wedge table formed between the V-shaped concave portion and the inclined surface causes the mounting table to move toward the front surface. It is firmly and securely fixed and held by the pair of front legs.

[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 a non-use state. The easel 1 for painting has a pair of left and right front legs 2 and 2 which are arranged in a V shape at a predetermined interval, and upper and lower end portions of both front legs 2 and 2 are formed by an upper joint 3 and a lower joint 4. A planar frame 5 is formed by connecting them. A rotating member 6 to which a rear leg 8 is attached is provided below the upper shell 3. The pivoting member 6 is rotatably supported about a horizontal axis by fitting pivot pins 7 projecting at both ends into fitting holes (not shown) provided inside the front legs 2 and 2. The upper end of the rear leg 8 is fixedly connected to the 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. The engaging stepped portion 8a is formed by cutting about 1/2 of the above. Then, in the non-use position, by engaging the engaging stepped portion 8a with the concave portion 9 provided in the central portion of the lower sleeve 4, as shown in FIG. 1 (b) and FIG.
Is protruding from the frame 5 and both front legs 2, without any sticking
It is designed to be housed in the space between the two. Although not shown, it is desirable to provide a stopper for locking and holding the engagement stepped portion 8a on the lower sleeve 4 when the rear leg 8 is in the unused position shown in FIG.

The lower end of the rear leg 8 has a pair of support rods 10, 10
It is connected and supported to both front legs 2 and 2 via. Each of the support rods 10 has its upper end pivotally connected to the inner portion of the front leg 2 at an intermediate position through a pivot pin 11, and has its lower end connected to the rear leg 8.
Is rotatably connected to both ends of a support pin 12 which is disposed at the lower end of the support pin so as to extend laterally therethrough. 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 elongated holes 15 and 15 extending in the longitudinal direction provided in both side walls 14 and 14 of the concave groove 13 facing each other. The pin 12 penetrates and is slidably attached in the vertical direction along the long holes 15, 15. A tension spring 16 is accommodated in the groove 13, and the upper end of the tension spring 16 is fixed to the rear leg 8 with a stopper 17 and
The lower end of the tension spring 1 is connected to the support pin 12.
The support pin 12 is urged upward by 6 without permission. When the rear leg 8 is folded and stored between the front legs 2 and 2 as shown in FIG. 1, both supporting rods 10 and 10 are also stored in the space between the front legs 2 and 2, and the rear leg 8 and FIG. As shown in (), the frame 5 is entirely accommodated in a flat frame 5.

On the other hand, the front legs 2 and 2 are provided with a plurality of holes 18 at predetermined intervals in the vertical direction, and a canvas mounting table 20 is attached by a plug member 19 inserted into the holes 18 at predetermined positions. It is supposed to be supported.

The mounting table 20 is formed of an elongated plate-like member, and as shown in FIG. 4, a V groove 22 having a downwardly extending inclined surface 21 along the front and rear surfaces is provided over the entire length. And a shallow guide groove 23 is provided on the upper surface. On the other hand, the plug member 19 is formed of a rectangular rod body that can be inserted into the hole 18, and has a locking projection 25 projecting from one end thereof, and the bottom surface 24 of the mounting table 20 is inclined inside the locking projection 25. A V-shaped recess 26 that engages with the surface 21 is provided, a wedge hole 27 is provided at the other end, and a wedge piece 28 that is fitted into the wedge hole 27 is provided.

In the painting easel 1 having the above structure, when the rear leg 8 is slightly rotated rearward from the unused position shown in FIG. 1, the tension spring 16 acts to support the support rods 10 through the support pins 12. 10 is urged backward, and in conjunction with this, the rear leg 8 is forcibly rotated at a stretch so as to bounce to the use position shown in FIG. Therefore, it is set to the use position by one-touch operation. In this use position, a pair of plug members 19 and 19 are inserted into the holes 18 and 18 of the left and right front legs 2 and 2 at symmetrical predetermined positions, and the mounting table 20 is mounted and supported between the plug members 19 and 19. Both plug members 1
When the wedge piece 28 is inserted into the wedge holes 27 of 9, 9, the plug member 1
9 is pulled toward the front leg 2 side, the V-shaped recess 26 of the locking projection 25 engages with the inclined surface 21 of the mounting table 20, and the mounting table is formed by the wedge effect of the V-shaped recess 26 and the inclined surface 21. 20 is firmly and securely fixed and held in a state of being pressed against both front legs 2 and 2.

[0013]

As described above, in the painting easel of the present invention, the V-shaped concave portion 26 of the stopper member 19 and the inclined surface 21 of the mounting table 20 are engaged with each other, and the mounting table 20 is provided by the wedge effect.
Is firmly and securely fixed and held to both front legs 2 and 2, and a stable supporting state can be obtained without unexpected rattling or dropping.
