Description

  The present invention relates to an art material box for carrying art materials such as paints, pastels, and crayons, and relates to a sketch material box (a sketch box) equipped with a sketch book and a folding picture rack for standing a canvas.

  An art material box provided with a picture rack that is folded so as to close the upper surface of the box when not in use is known. This kind of art material box usually has a structure in which the lower edge of the plate-shaped picture rack is connected to the front edge (the user side edge) of the art material box with a hinge, and the art material storage part is pulled out to the front. It can be pulled out. The user places the art material box on the desk, raises the picture frame and supporting material, fixes the angle of the picture frame with screws, attaches a canvas or sketch book to the front of the standing picture frame, and pulls out the drawer to the front side for use .

  Since the support material for supporting the standing picture frame is usually attached to both sides of the picture frame, two screws with knobs must be screwed to fix the angle of the picture frame. In addition, the canvas and sketch book are attached by being sandwiched in the vertical direction between a receiving hook and a presser hook attached to the lower and upper edges of the picture rack. For this attachment, a presser bar on the upper edge of the picture frame is provided so as to be able to move up and down, and the presser bar can be fixed with screws at a position corresponding to the size of the canvas or sketch book.

  Since the drawing material box having this structure has a double structure of the drawer and the outer box (the picture rack is a cover plate of the outer box), the box is heavy and the size is increased. In addition, when the picture rack is folded, the receiving hook and presser hook for attaching the canvas and sketch book remain protruding outside the box (above when placed on the desk). Get in the way. Also, the assembly and storage operations are difficult when starting to draw or finishing drawing. In addition, the bottom edge of the frame is stained with paint or pastel powder, but when it is folded, the dirty surface is exposed outside the box. Easy to adhere to. For this reason, it has been almost impossible to use the conventional art material box having the above-described structure when it is carried in a basket and used when drawing a picture on the road.

  On the other hand, the cover plate of the art material box is connected to the rear edge of the box (the edge on the side opposite to the user when placed on the desk to draw a picture) with a hinge, and the cover plate is tilted up to form the picture frame Boxes have also been proposed. An art box with this structure can be drawn immediately by opening a cover plate and attaching a canvas or sketch book so that it fits inside the cover plate.

  However, in order to maintain the standing position of the lid plate, the art material box with this structure must be provided with a stopper near the hinge or a support string at a position on the front side of the lid plate. When it is provided, a large force is applied to the stopper, and when a support string is provided, the string becomes an obstacle and a large canvas or sketch book cannot be attached. Furthermore, the box tends to fall backward while drawing a picture. For this reason, when trying to draw a large picture, there is a disadvantage that the box becomes larger than the size necessary for accommodating the painting material, and the weight becomes heavy, which is inconvenient to carry.

  An object of the present invention is to provide an improved art material box in which a picture can be drawn by using an open lid plate as a frame, that is, holding a sketch book or a canvas on a diagonally standing lid plate.

  As for this invention, the operation at the time of the assembly after starting drawing and the storing after finishing drawing is easy, and since a canvas and a sketch book larger than the size of the box can be attached, the box can be made small. The part that gets dirty with paint and pastel powder is inside the box when stored, so you don't get dirty when you carry it, or when you put it in the bag, you don't get dirty inside the bag. An object of the present invention is to provide an art material box that can be easily accommodated in a bag or the like by being a box shape having a thin rectangular shape when it is closed.

  The art material box of the present invention includes a box body 1, a cover plate 2, a support member 3 that holds the cover plate 2 at a desired angle, and a slide body 4. The box body 1 is a flat box having an upper surface opened, and the upper surface opening is closed by the cover plate 2 or the cover plate 2 and the plate-shaped support member 3. The slide body 4 is guided by a longitudinal guide 15 provided on the side or bottom surface of the box body 1 so as to be movable rearward of the box body 1.

  The rear end (base end) of the support member 3 is pivotally attached to the rear end of the slide body 4 so as to be swingable about an axis parallel to the rear edge 19 of the box body 1. The front end (front end) of the support member 3 is pivotally mounted at an intermediate position in the front-rear direction of the lid plate 2 so as to be swingable about an axis parallel to the rear edge of the box body 1.

  When the cover plate 2 that closes the upper surface opening of the box body 1 is opened and the slide body 4 is moved rearward, the art material box having the above structure has a support material 3 pivotally attached to the rear end of the slide body 4. Stands obliquely and holds the opened lid plate 2 in an oblique standing posture. The angle of the standing lid plate 2 can be set by defining the rearward movement end of the slide body 4.

  The weight of the canvas or the sketch book 5 leaning on the standing cover plate 2 is supported by the slide body 4 moved to the rear of the box body. When the cover plate 2 is closed and the slide body 4 is pulled into the side surface or the lower surface of the box body 1, the support member 3 is in a state of being laid down on the upper surface or the side surface of the box body 1.

  In a preferred structure of the present invention, a pressing bar 22 protruding toward the box body 1 is provided at the front edge of the lid plate 2, and the lid plate 2 is provided so that all four sides can be separated from the box body 1. It is a structure provided with urging means 32 and 33 for urging the material 3 toward the box body 1 in the direction of lying down. As the urging means, a structure in which the rear edge of the slide body 4 and the rear end of the support member 3 are urged by a spring hinge or a spring hinge incorporating a winding spring is particularly excellent. As another structure, there can be mentioned a structure in which a tension spring or a rubber string 33 is provided to urge the front end of the support member 3 or the cover plate 2 toward the rear edge 19 of the box body 1.

  In this structure, a canvas or sketch book whose vertical dimension is larger than the longitudinal dimension of the cover plate 2 is moved up and down by the pressing force 22 and the rear edge of the box body 1 by the biasing force of the biasing means 32 and 33. In the sandwiched state, the lid plate 2 is held along the front surface of the standing lid plate 2. A large canvas or sketch book pushes up the presser bar 22 and thus the raised cover plate 2, so that the urging force of the urging means 32 and 33 is increased and is held with a stronger force. Since the dimensions of the canvas and sketch book are absorbed by the displacement of the urging means, it is not necessary to adjust the height of the presser bar according to these dimensions.

  The art material box of the present invention becomes a flat box shape without protruding parts when closed when the part dirty with paint etc. is closed, so it does not stain clothes and bags and is also portable Convenient.

  In addition, since the angle of the raised cover plate is determined by the position of the moving end of the slide body, the art material box of the present invention does not need to be adjusted every time it is used, and can be set to a desired angle. . Furthermore, the canvas and sketch book can be attached and the drawing material after drawing can be stored with few operations.

  Further, in the art material box having the above preferable structure, a canvas or a sketch book having a size substantially larger than the size of the box can be held in a state of being sandwiched between the presser bar 22 and the rear edge of the box body 1. For example, it can be attached in the state where the canvas or sketch book in the range of F2 vertical to F5 vertical, F3 horizontal to F6 horizontal is pressed with a presser bar with an F3 size drawing material box with the short side in the front-rear direction.

  Smaller canvases and sketchbooks can be clipped or held with an auxiliary plate, and of course can be drawn simply against the lid plate.

  The present invention will be further described below with reference to the drawings showing preferred embodiments of the present invention. In the figure, 1 is a box body, 2 is a lid plate, 3 is a plate-like support member (hereinafter referred to as “support plate”), and 4 is a plate-like slide body (hereinafter referred to as “slide plate”). .

  The box body 1 is a shallow rectangular box having an open top surface, and includes a bottom plate 11, a front edge plate 12, both side plates 13, a rear edge plate 14, and a guide material 15. The front edge plate 12, the side plates 13 and the rear edge plate 14 have the same height, and the height is about 1/5 to 1/20 of the dimension of the side of the box body. A receiving groove 16 is formed behind the upper edge of the rear edge plate (on the side opposite to the front edge). A guide member 15 having an L-shaped cross section is attached to the outer surface of the side plates 13, and a guide slit 18 is formed between a portion 17 of the guide member extending downward from the box body and the bottom surface of the bottom plate 11. .

  The slide plate 4 is formed of a plate material having the same width as the bottom plate 11 of the box body and slightly longer in the front-rear direction, and both sides in the width direction are slidably fitted into the guide slits 18. The slide plate 4 has a U-shape in which the central portion is notched from the rear edge side, and the edge on the front edge side of the notch is a beveled edge 41. A plurality of screw holes 42 are provided at a position below the rear edge member 14 of the bottom surface of the box body, and a stopper 43 is screwed into one of the screw holes. The rearward movement end of the slide plate 4 is defined by the contact between the oblique edge 41 and the stopper 43, and the position of the movement end of the slide plate 4 is determined by moving the stopper 43 to another screw hole 42. Can be changed.

  The lid plate 2 has a concave shape with a central portion cut out in a trapezoidal shape from the rear edge side, and is connected to a support plate 3 made of a convex plate material by a hinge 21 at the top side of the trapezoid. The position of the hinge 21 is substantially the center of the cover plate 2 in the front-rear direction, and the concave and convex portions of the cover plate 2 and the support plate 3 are just fitted into each other, and in a state of being flat, Close the top opening. On the front edge of the cover plate 2, a presser bar 22 extending toward the box body 1 side is provided. The lid plate 2 is connected only to the support plate 3 in the structure described above, and is not connected to the box body 1.

  A square member 31 is fixed to the lower surface of the rear edge of the support plate 3, and the wide rectangular member 31 and a narrow rectangular member 44 fixed to the upper surface of the rear edge of the slide plate 4 are connected by a spring hinge 32. The square members 31 and 44 have a height equal to the height of the box body 1, and the spring hinge 32 urges the support plate 3 in a direction to fall on the box body 1 side. . The cover plate 2 having the center portion in the front-rear direction connected to the tip side of the support plate 3 is urged toward the box body 1 through the support plate 3 by the urging force of the spring hinge 32. The upper surface opening of the box body 1 is closed together with the support plate 3 that has fallen down.

  As shown in FIG. 4, a cushion material 45 is attached to the front surface of the narrow-angle material 44 at the rear edge of the slide plate. As this cushion material, a rubber tube extending in the longitudinal direction of the narrow-angle material 44 can be used. The presser bar 22 on the front edge of the cover plate is inclined in a slightly acute direction with respect to the lower surface of the cover plate 2, and the front upper part of the front edge plate 12 of the box body also corresponds to the angle of the presser bar 22. It becomes the inclined surface 12a. The slide plate 4 is moved forward, and the presser bar 22 is moved to the front of the front edge plate 12 of the box body at the position where the cushion material 45 is in contact with the rear edge plate 14 of the box body and is slightly crushed. The plate 2 is closed.

  The art material box having the above structure pushes the rear edge of the slide plate 4 forward from the closed state to disengage the presser bar 22 from the inclined surface 12a of the front edge plate, pushes up the front edge of the cover plate 2, and slides the slide plate. It is opened by pulling 4 backward and lifting the front edge of the lid plate 2. When the front edge of the cover plate 2 is lifted, the support plate 3 swings around the rear edge and stands up, and the cover plate 2 swings around the tip side of the support plate 3 and opens. At this time, the rear edge of the cover plate 2 is locked to the receiving groove 16 provided on the rear edge plate of the box body or behind the rear edge plate 14 by the biasing force of the spring hinge 32.

  As shown by a broken line in FIG. 1, the canvas or sketch book 5 whose vertical dimension is larger than the front-rear dimension of the cover plate 2 is hooked on the presser bar 22 of the cover plate and lifted together with the cover plate 2. By being fitted into the receiving groove 16 provided on the rear edge plate, the rear edge plate is held in a standing posture. At this time, the cover plate 2 is attached to the back surface of the canvas or sketch book with the rear edge away from the box body 1. The canvas or sketch book is pressed against the presser bar 22 and the receiving groove 16 by the biasing force of the spring hinge 32. And the upper and lower edges are held.

  At this time, since the spring hinge 32 also biases the slide plate 4 backward, the slide plate 4 is positioned at the rearward movement end defined by the stopper 43. Therefore, the angle of the canvas or sketch book to be held can be changed by adjusting the position of the rearward moving end of the slide plate 4, or by changing the screwing position of the stopper 43 in the structure of the above embodiment.

  A canvas or sketch book whose vertical dimension is smaller than the longitudinal dimension of the lid plate 2 can be drawn against the lid plate 2 that is raised by being latched behind the receiving groove 16 or the rear edge plate 14. If the canvas or sketch book is to be held more stably, it is stopped on the cover plate 2 with a clip, or a drawing board 51 as shown in FIG. 5 is prepared and held via this drawing board. The drawing board 51 is a board in which the vertical dimension is about the front-rear dimension of the cover plate 2 and the receiving collar 53 is fixed at a position where the dimension from the upper edge 52 is smaller than the vertical dimension of the canvas or sketch book to be held. The lower edge of the canvas or sketch book to be used is placed on the receiving bowl 53, the upper edge of the canvas or sketch book protruding from the upper edge of the drawing board 51 is hung on the holding bowl 22, and the lower edge of the drawing board 51 is placed on the receiving groove 16 of the box body. Lock to. The canvas and the sketch book are held in a state where the upper and lower edges are held by the urging force of the spring hinge 32 and are sandwiched between the barb 22 and the barb 53.

  The user places the art box on his lap or puts the upper arm of one hand under the art box and supports it, and draws the picture using the paints and pastels contained in the box body. Can do. In the above embodiment, since the slide plate 4 is notched, when the art material box is supported by the arm, the portion extending backward from the box body 1 of the slide plate 4 is grasped by hand, thereby supporting the art material box more stably. it can.

  In the above example, the spring hinge 32 is used as the biasing means for biasing the rear edge of the lid plate 2 toward the rear edge 19 of the box body when the cover plate 2 is erected. Of course, it is also possible to provide it at the pivotal connection between the base end of the support plate 3 and the rear edge of the slide plate 4. Further, only the hinge is provided at the pivotally attached portion, and a tension spring or a rubber string is stretched between the front end portion of the support plate 3 or the cover plate 2 and the rear edge 19 of the box body 1, and the cover plate 2 is attached. A structure is also possible in which the rear edge is biased toward the rear edge 19 of the box body when it is erected. In FIG. 1, the crossing direction of the rubber string 33 when using the rubber string is illustrated by an imaginary line. The illustrated structure is such that the center of a rubber cord 33 with both ends locked to both ends of the rear edge of the box body 1 is hooked on the tip of the support plate 3 or a hook provided on the cover plate.

  Since the slide plate 4 only needs to slide backward relative to the box body 1, the slide plate 4 is placed on the desk or on the knee, and the box body 1 is pulled out to the near side with respect to the slide plate 4. It can also be set as a structure. In addition, if a canvas or sketch book slightly larger or smaller than the size of the lid plate 2 is simply placed on the standing lid plate, the rear edge of the lid plate 2 is hinged to the rear edge of the box body. In this case, the urging means is unnecessary.
