The present invention relates to an easel stand used to draw a picture or display a picture, a picture, a menu board or a guide board.

As is well known, the easel stand is used to place a drawing board for drawing or a photograph, a picture, a menu board or a guide board for viewing by many people.

The easel stand has to vary the distance between the upper and lower pedestals according to the size of the drawing board, the board for the menu and the shape of the guide board, and the representative structure of the Korean Utility Model Publication 1993-0007283; Hereinafter referred to as "quotation design 1").

This cited proposal 1, as shown in Figure 1, the three legs 102 by the one side of the body 104 is folded material and the drawing board holder 107 installed on the upper section 103 of the adjustment screw 108 In the configuration of a conventional easel 100, which combines a drawing board pedestal 110, which can be fixed by means of the pin shaft 113 of the leg, and which can be separated and coupled, protrudes and adjusts the adjusting rod 106 on the body 104. On the back side of the liver 106 is formed a ruler piece (106a) which can hold the inter-segment (103), and the lower side engaging the slide section 115 with the coupling piece (116) protruding to the inter-segment (103) and the front Coupling pieces 102a are coupled to each of the legs 102 by a slide type, but a hanging piece 102b is formed on the control pieces 102a, and a drawing piece protruding from the slide plate 115 on the drawing board base 110 on the front side. 116 is coupled to the pin shaft 113 that can be moved along the uneven groove 112 in the control rod 102a .

Therefore, this allows the pin shaft 113 to be coupled to any one side of the uneven groove 112 of the pedestal 110 while raising and lowering the adjustment lever 102a coupled to the slide, thereby fixing the position of the variable pedestal 110. In addition, the coupling piece 116 protruding between the slide 115 and the coupling recess 114 between the pedestal 110 should be coupled.

Therefore, it is required that the length of the pedestal 110 is considerably long, in which the uneven groove 112 of the long hole is to be formed, and the pin shaft 113 is formed in the adjusting section 102a, and the pedestal 110 is interstitial. The coupling piece 116 protruding from the slide section 115 and the pedestal 110 between the pedestal 110 should be provided so as to be coupled to the 103. ), The adjustment of the position between the pin shaft 113 and the uneven groove 112, and the operation hassle to combine the coupling piece 116 of the longitudinal section 103 and the coupling recess 114 of the pedestal 110 Due to the inconvenience of use, there is a problem that the manufacturing cost inevitably increases in the production of a complex structure.

In addition, the pedestal 110 is to be folded with careful attention so that the position of the left and right adjusting section 102a and the engaging piece 116 of the longitudinal section 103 in a straight line, even when folded. If the force is applied in this process, the pin shaft 113 and the concave-convex groove 112 and the coupling piece 116 and the coupling recess 114 is damaged, there is a high possibility that it becomes impossible to use.

In addition, the cited design 1 has a structure that is supported by the body 104, the front and rear legs are fully deployed, and is to be stored by the Velcro tape 118 at both ends of the string 117 only when folded. .

Therefore, when the wind is blowing strongly or an external force is applied in the process of deploying and using the bridge 102, one of the bridges 102 collapses and loses its center while falling, causing a picture or exhibit to be damaged frequently. In addition, when moving to the vicinity in the deployed state is to inconvenience the need to hold the leg 102 separately.

An attempt to prevent this can be examined by Korean Utility Model Publication No. 1990-0004966 (designation name: easel; hereinafter referred to as “quotation design 2”).

Proposition 2 is provided with two support rods 204 in the center of the body 201, the height adjustment 202 and the lower height adjuster 203 for high and low adjustment along the support interval 204 ), And a pivot 206 integrally assembled with the strut 207 having the upper rear top pin 207 'and the lower pin 207 "of the main body 201 to the interlocking fixture 205. It was inserted so as to rotate, and to fit the hole of the bottom end of the angle adjustment opening (208).

Therefore, this reference 2 is that the state of the leg is maintained by the shape of the angle adjuster 208 and the pins (207 ', 207 "fitted to it), the support state is not strong enough to be easily damaged by external forces Is there.

In addition, other types of easel can be found in the Republic of Korea Utility Model Publication 1996-0009844 (designation name: painting easel; hereinafter referred to as "quoting citation 3"). This proposal 3 is a common painting easel, connecting the connection between the tube body 303, 304 and the support tube 309 by the ring chain 310, and the upper portion of the tube body 303, 304 One of the plurality of through-holes 313 is formed by fixing by bowling the plate support bar 311 is coupled to the cap 305.

Therefore, although the citation proposal 3 can be used by adjusting the position of the plate support bar 311 in accordance with the drawing board or exhibits, it is inconvenient to assemble and remove the plate support bar 311 from time to time. It is a sieve because there is a problem that can not be used if you lose the plate support bar 311 during the handling process.

In addition, since the proposal 3 is connected between the connection between the tube 303, 304 and the support tube 309 in a ring chain, the role of controlling the gap between the tube 303, 304 can be expected, but in any direction If an external force is applied in a narrowing direction, there is a high risk of losing balance and falling.

The first object of the present invention provides an easel stand that can easily adjust the height of the pedestal with a simple structure in spite of various specifications of the drawing board or the exhibition to solve the problems of the cited designs.

 The second object of the present invention is to provide an easel stand which does not cause an increase in volume or operational inconvenience due to the support when carrying.

The third object of the present invention is to provide a stable support structure of the easel stand, which is firmly supported by the gap between the legs during deployment, and does not flow by an external force.

In order to achieve this object, the present invention is a known easel stand consisting of a vertical strut with a stretchable front strut and a rear strut is fastened by a fastening portion, and can be elevated above the fastening portion, and provided with a clip on the top thereof. To
