Description

  The present invention relates to a board device suitable for application to a lecture style such as so-called active learning.

  In recent years, lectures that incorporate a style called active learning are increasing. Active learning has been recognized as a teaching / learning style in which students and children work voluntarily and actively and cooperate with each other, rather than teaching teachers unilaterally in the form of lectures.

  In adopting such a style, whiteboards are one of the indispensable items for aggressive announcements and collaborative work using the board. A conventional whiteboard is generally used in a self-standing manner near a table (for example, Patent Document 1).

JP 09-299172 A

  However, since the board device of the conventional type is arranged and used in a position that does not interfere with a desk or the like, the present inventors have conducted various verifications. It became clear that there were challenges.

  First, as shown in FIG. 13, by arranging a large number of whiteboards 101, the whiteboard 101 becomes a shielding plate, and there arises a problem that it becomes difficult to see lectures of the lecturer T and presentations of the students S.

  Further, when the whiteboard 101 is used in units of groups, there is a problem that neither the instructor T nor the student S knows the progress of each group, and the instructor T has to travel around.

  Furthermore, the whiteboard 101 divides the circle of group discussion into two parts, and there is a problem that the moderator (secretary) S0 turns away from the member student S and cannot enter the discussion circle.

  In addition, since the whiteboard 101 blocks a flow line indicated by a broken-line arrow in the drawing between the desks D and D, there is a problem that the act of moving the student is hindered.

  Furthermore, if the whiteboard 101 is arranged on the passage after use, the passage width in the classroom becomes narrow, which causes a problem that it is difficult to clear and prepare.

  In addition to the above, there is a problem that the whiteboard of the type leaning diagonally remains difficult to write and to see.

  An object of the present invention is to solve the above-described problems and to provide a board device that is particularly suitable when applied to a lecture style such as active learning.

  In order to achieve this object, the present invention takes the following measures.

That is, the board device of the present invention includes a board and a support that supports the board, and a recess into which the top of the furniture with the top can be inserted into a part of the support, and the recess. A vertical support shaft that is positioned and rotatably supports the board, and the support body includes a base that is disposed along the floor surface, an upright portion that stands up from the rear end of the base, and the upright portion. An upper frame and an intermediate frame extending along the base from the upper end portion and the intermediate portion of the section, the recess is provided between the intermediate frame and the base, and the board is interposed between the upper frame and the intermediate frame via a support shaft. It is characterized by having attached .

  With such a configuration, when the top plate is inserted into the recess, the support shaft is positioned on the top plate, and the board surface is hung on the desk. For this reason, the person sitting around the top board can see the board surface of the board up close, and if the angle is changed around the support shaft, the board surface can be directed to the person sitting at any position on the top board. The discussion can be developed around Furthermore, if it is inverted around a vertical support shaft, the board surface can be easily directed to those who are not seated around the top plate, and the top and bottom can be reversed like rotation around the horizontal axis. Because it is not available, the board can be easily introduced to the teacher and other groups. In addition, if a board is installed on such a top plate, students and lecturers can act dynamically because the flow lines between the tables are not blocked as much as possible, and the visibility between the groups is improved and discussions are possible. Splitting is also avoided, and preparation and cleaning up are easy.

  In order to improve the convenience of use of the board surface and the visibility from the surroundings, the support body has a predetermined gap between the first side to the third side of the board whose upper frame, upright part and intermediate frame are rectangular at a predetermined position of the board. It is desirable that the fourth side is an open portion at the predetermined position.

  In this case, in order to prevent the article from being placed in the rotation zone of the board, it is effective that the intermediate frame has an extension portion extending to the vicinity of the fourth side of the board at a position beyond the support shaft. Is.

  More preferably, the extension is provided with a handle at the extension end.

  On the other hand, in order to stabilize the self-standing state of the board device while avoiding interference with the legs of furniture with a top plate as much as possible, the support further includes an auxiliary base orthogonal to the base, and the base and the auxiliary base It is preferable that the upright portion is erected from the crossing portion or the vicinity thereof.

  In particular, a configuration in which the base is inclined forward and downward from the rear end portion toward the front end portion is effective.

  At that time, in order to suitably balance the mobility of the support and the good writing state on the board board surface, fixed casters that do not swing are arranged at the front end of the base and both ends of the auxiliary base. It is desirable.

  In these cases, it is particularly preferable that a weight for lowering the center of gravity of the support is disposed at a low position of the upright portion.

  In order to increase the stability when using the board and to enable easy board operation when browsing, the board that has arrived at the specified position is pulled into the locked state and the operating force is applied to lock the board. It is convenient to provide a lock mechanism for releasing the at the intermediate frame or the upright portion.

  Since the present invention has the configuration described above, it can be used by hanging the board on the top board, and the person sitting around the top board or not sitting by rotating horizontally around the support shaft The board is on the top board so that it does not block the passage, and the field of view of the surrounding space is secured as much as possible. An extremely useful board device can be provided.

FIG. 5 is a side view showing a state in which a part of FIG. 3 is broken and the board 1 is rotated by 90 ° from the predetermined position in FIGS. 1 to 4, and FIG. 6 shows the base 3 and the upright portion 5. It is the partially broken top view shown.

  The board device B includes a board 1 and a support body 2 that supports the board 1 so as to be suitably applicable to active learning (AL) learning. A recess 2a is provided in a part of the support 2, and the board device B is moved to a position where the recess 2a receives the top board a1 of the furniture A with the top board, and the board 1 is cantilevered on the top board a1. In this state, the board 1 is overhanged, and the board 1 can be rotated around the vertical axis m provided on the recess 2a at that position.

  More specifically, the board 1 is obtained by attaching a frame 12 around a rectangular face plate 11, and the face plate 11 is a semi-transparent material formed by bonding two polished glasses. 11 is a seamless structure that shows people behind the scenes and movements, and does not block the space. Moreover, both surfaces of the face plate 11 can be described with markers, and the description content has a structure that does not affect the back surface as much as possible. Of course, a white board may be used instead of the translucent face plate.

  One support 2 includes a base 3, an auxiliary base 4, an upright portion 5, an upper frame 6, and an intermediate frame 7. The concave portion 2 a is formed between the intermediate frame 7 and the base 3, and the upper frame 6 and the intermediate frame are formed. 7, the board 1 is mounted via vertical support shafts 21 and 22.

  As shown in FIGS. 4 and 6, the base 3 is mainly composed of a long plate-shaped iron plate 31. The base 3 is covered with a decorative cover 32 and does not swing on the front end 3 a side. The casters 33 are attached and arranged along the floor surface F.

  The auxiliary base 4 includes a flat square pipe 41 that is joined to the rear end portion 3b of the base 3 by welding or the like and extends in a direction orthogonal to the base 3, and a decorative cover 42 that covers the square pipe 41. The fixed casters 43 that do not swing are attached to both ends.

  Due to the difference in support height between the casters 33 and 43, the base 3 is inclined in a tapered shape so as to be lowered from the rear end portion 3b toward the front end portion 3a.

  The upright portion 5 includes a first support column 51 made of a round pipe material standing up from a center position of the rear end portion 3b of the base 3, specifically, the auxiliary base 4 joined to the rear end portion 3b, and the first support column. The second support column 52 made of a round pipe material that stands up from the base front end 3a side than 51, and the coupling tool 53 that connects between the first support column 51 and a predetermined height position of the second support column 52 are provided. The 1st support | pillar 51 and the 2nd support | pillar 52 are comprised, for example with steel, and the connection tool 53 is comprised with the iron plate. Between the first support column 51 and the second support column 52 at a low position of the upright portion 5, a plurality of iron plates are stacked to constitute a weight 54 that lowers the center of gravity of the upright portion 5. The first support column 51, the second support column 52, the coupling tool 53, and the weight 54 are housed in a cover 55 formed by bending a sheet metal, and a part of the first support column 51 and the second support column 52 is directed upward from the cover 55. It is in a protruding state.

  The upper frame 6 is continuously connected to the upper end portion of the upright portion 5 by bending the upper end side of the first support column 51, extends along the base 3, and supports the board 1 at the extended end portion. The first bearing 61 is arranged.

  The intermediate frame 7 is continuously connected to the intermediate portion of the upright portion 5 by bending the upper end side of the second support column 52 and extends farther than the upper frame 6 along the base 3. A second bearing 71 that supports the board 1 is disposed in the middle portion. The first bearing 61 and the second bearing 71 are located on the same vertical axis m, and the board 1 is rotatably attached to these bearings 61 and 71 via support shafts 62 and 72. That is, the board 1 is supported in a cantilevered position with respect to the upright portion 5 in the horizontal direction.

  Accordingly, the upright portion 5 is located at a predetermined position of the board 1 shown in FIG. 4, that is, at a position where the board surface of the board 1 is parallel to the upper frame 6, the intermediate frame 7, and the base 3 and these are overlapped in plan view. The frame 6, the upright part 5 (particularly the first support column 51), and the intermediate frame 7 are connected to the first side 1 a, the second side 1 b, and the third side 1 c along the frame 12 of the rectangular board 1 through a predetermined gap. There is a partially surrounding relationship, and at the predetermined position, the fourth side 1d side is an open portion 5x where no component of the upright portion 5 exists. The intermediate frame 7 extends beyond the support shaft 71 to the vicinity of the fourth side 1d of the board 1 to form an extension portion 7x. The handle portion can be hooked or gripped by the fingers on the extension end of the extension portion 7x. There is provided a handle 70 having. As shown in FIG. 7, the handle 70 is integrally formed with resin together with the boss portion 70 a, and is attached by fitting the boss portion 70 a to the intermediate frame 7.

  A recess 2 a is formed at a position partially surrounded by the intermediate frame 7, the upright portion 5 (specifically, the inner surface 55 a of the cover 55) and the base 3. For example, as shown in FIG. 2, the furniture A with a top plate used together with the board device B has a height dimension h1 from the floor F to the top surface of the top plate a1 of 720 mm, which is a recent standard height, Similarly, the height dimension h2 from the floor F to the lower edge 7a of the intermediate frame 7 that forms the recess 2a of the board device B is set to 750 mm. The depth is set such that the dimension w1 from the handle 70 provided at the front end 7b of the intermediate frame 7 to the inner surface 55a of the cover 55 is 562 mm, and the board 1 is configured such that the vertical dimension h3 is 900 mm and the horizontal dimension w2 is 700 mm. The diameter φ1 of the round pipe constituting the first column 51, the second column 52, the upper frame 6 and the lower frame 7 is 25 mm, and the gap dimension h4 from the lower side 1c of the board 1 to the round pipe constituting the intermediate frame 7 is 25 mm. The shortest depth dimension w3 from the side edges 1b and 1d of the board 1 to the round pipe constituting the first support column 51 is also set to 25 mm. That is, the height dimension from the floor surface F to the lower side 1c of the board 1 is 800 mm, and the height dimension from the floor surface F to the upper side 1a of the board 1 is 1700 mm. Further, the dimension w4 from the inner surface 55a of the cover 55 to the axis m of the support shafts 21 and 22 is 172 mm, the minimum protrusion dimension w5 of the handle 70 from the sides 1b and 1d of the board 1 is 40 mm, and the board 1 is shown in FIG. When the board 1 is rotated by 90 ° from the predetermined position, the maximum projecting dimension w5 of the handle 70 from the center in the thickness direction of the board 1 (ie, the axis m) is 390 mm. That is, as shown in FIG. 9, if a person C with a standard physique extends his arm from the sitting position with his marker, he can write on the entire board surface width dimension w2 and height dimension h3. The height from the floor F is set. In addition, by having a hanging function on the desk, it is possible to bring the board close to the clerk C and other seated persons D and E, assuming the use by 2 to 3 persons. By rotating around the center m, everyone can proceed with discussion while confirming the contents of the board 1.

  In order to fix the board 1 at a predetermined position, a lock mechanism 9 shown in FIGS. 1 and 7 is provided. The lock mechanism 9 is assembled to a boss portion 70a of the grasp 70, and has an operating portion 91 that can project and retract up and down, and a spring (not shown) that urges the operating portion 91 upward. The operating portion 91 is a board. 1 has a groove 91a corresponding to the thickness of 1 and an inclined surface 91b for immersing and calling the lower side 1c into the groove 91a when the lower side 1c of the board 1 approaches, and the groove 91a at a predetermined position shown in FIG. When the lower side 1c is received, the upper side protrudes upward and enters a locked state. The locked state can be easily released by lightly pressing down the slope 91b.

  As a result, both ease of movement and fixation are achieved. That is, by allowing the board 1 to move around the support shaft m with a light force, it is possible to handle the learning smoothly without disturbing the learning of the student so that the AL learning can be smoothly circulated. On the other hand, the board 1 can be fixed by the lock mechanism 9 in the scene to be fixed. In other words, it takes into account that when writing, you need a sense of stability that you can write without having to hold it with your hand.

  Further, the board device B can be stacked in the horizontal direction as shown in FIG. That is, the base 3 extends to a position close to the floor, the auxiliary base 4 is lifted by the caster 43, and the base 3 is in a positional relationship that can be submerged under the auxiliary base 4. 4, the position where the inner surface 55a of the cover 55 of the next board device B abuts and the bases 3, 3 of both board devices B, B are closely adjacent to each other is defined as the stack position. The stack pitch is substantially equal to the depth dimension of the cover 55, and the maximum number of stacks N is set to three board devices B in this embodiment.

  On the other hand, as shown in FIGS. 1 to 3, pen cases 81 and 82 and a sticky note case 83 as optional members can be attached to the cover 55 using magnets.

  Further, a space partially surrounded by the first support column 51, the second support column 52, the upper end of the cover 55, and the lower side 1c of the board 1 that protrudes from the cover 55 can also be used as a place for placing an article. .

  As described above, the board device B of the present embodiment includes the board 1 and the support body 2 that supports the board 1, and the top board a <b> 1 of the furniture A with the top board is inserted into a part of the support body 2. Since the recessed portion 2a that is possible and the vertical support shafts 21 and 22 that are positioned on the recessed portion 2a and rotatably support the board 1 are provided, the top plate a1 is placed inside the recessed portion 2a as shown in FIG. Is inserted, the support shafts 21 and 22 are positioned on the top board a1, and the board surface is hung on the desk.

  For this reason, as shown in FIGS. 9 and 10, persons C, D, E, etc. who are seated around the top board a <b> 1 can see the board surface of the board 1 close to each other, and the angle around the support shafts 21, 22. The board surface can be directed to the person sitting at any position on the top board a1, and the discussion can be developed centering on the board B. Since the board 1 of this embodiment uses a transparent face plate, there is no feeling of pressure even when placed close to the board. Further, if the board 1 is reversed around the vertical spindles 21 and 22, it can be used for a person who is not seated around the top board, for example, a person F standing behind the board 1 or another desk or table. Since the board surface can be easily directed to the seated person G0, G1, G2, G3, etc., the top and bottom of the board surface will not be reversed like the rotation around the horizontal axis. The board surface of board 1 can be easily introduced to the group. In addition, if the board 1 is installed on such a top board a1, the flow line between the tables as shown by the broken line arrow in FIG. 10 is not blocked as much as possible, so that the lecturer and the student can act dynamically. It also improves visibility between groups, avoids disrupting discussions, and makes preparation and cleaning up easier. Even after use, since the board device 1 is thrust into the lower limb space of the top board a1 and does not dissipate on the passage, the passage width in the classroom does not become narrow, and it is easy to clean up and prepare. Since the board 1 is also supported upright, it is easier to write and view than a board leaning diagonally.

  In particular, the support 1 includes a base 3 disposed along the floor surface F, an upright portion 5 standing from the rear end portion of the base 3, and an upper end portion and an intermediate portion of the upright portion 5 along the base 3. An extending upper frame 6 and an intermediate frame 7 are provided, a recess 2 a is provided between the intermediate frame 7 and the base 3, and the board 1 is attached between the upper frame 6 and the intermediate frame 7 via support shafts 21 and 22. Because it is configured, if the base 3 is inserted into the lower limb space of the furniture A with a tabletop such as a table, the board surface of the board 1 can be easily overhanged on the desk, and the casters 33 and 43 are attached. Combined with being, it becomes easy to take in and out. Further, since the base 3 extends in the same direction as the upper frame 6 and the intermediate frame 7, it is difficult for the feet to naturally interfere by being inserted toward the center of the top plate a <b> 1.

  Further, the support 2 has a first side 1a, a second side 1b, and a third side 1c of the board 1 in which the upper frame 6, the upright part 5 and the intermediate frame 7 are rectangular at predetermined positions of the board 1 through a predetermined gap. Since it is in a partially surrounding relationship and the fourth side 1d side is an open portion 5x at the predetermined position, as shown in FIG. 11A, the upright portion 5 (particularly the first support column 51) is moved or written on the board surface. It can be used as a handle at the time, can also prevent fingering, and since there is nothing blocking the board surface on the open part 5x side, as shown in FIG. 9, from a person sitting around the top board a1 The field of view also becomes good.

  At this time, the intermediate frame 7 does not need to be extended further if the support shaft 22 can be provided. However, the support 5 has the open side 5x on the fourth side 1d side of the board 1, and therefore, as shown in FIG. If an article such as a PET bottle, a notebook, or a pen case is present on the rotation zone Z when returning from the proper rotation position to the predetermined position in FIG. On the other hand, since the extension portion 7x extending to the vicinity of the fourth side 1d of the board 1 is provided at a position beyond the support shaft 22 of the intermediate frame 7, the extension portion 7x is like an icon indicating the rotation region of the board 1. It can serve as a means for preventing an object from being placed in the rotation zone Z.

  And since the handle 70 is provided in the position where the eyes of the extension end of the extension part 7x are gathered, the rotation zone Z is more clearly recognized and the board device B is moved as shown in FIG. In this way, it is possible to prevent the bearing from being overwhelmed by inadvertently grasping the side 1d on the opening portion 5x side of the board device 4, and the mobility is further improved. In particular, since the intermediate frame 7 is slightly above the top plate a1, the board device B can be appropriately moved by grasping the handle 70 even when seated.

  Furthermore, since the support body 1 includes an auxiliary base 4 orthogonal to the base 3 and the upright portion 5 stands up from the vicinity of the crossing portion of the base 3 and the auxiliary base 4, the top plate a1 extends to the inner side of the recess 2a. Even if it is accepted, only the base 3 is basically inserted into the lower limb space of the furniture A with the top board, and the board device B can be kept in an independent state while avoiding interference with the legs of the furniture A with the top board as much as possible. It can be stabilized.

  At that time, since the base 3 is inclined forward and downward from the rear end 3b toward the front end 3a, the base 3 sinks into, for example, the legs of the table, particularly under the leg blades, as shown in FIGS. (Intrusion) is easy and the base 3 can be pushed into the lower limb space without interference as much as possible.

  In addition, since the fixed casters 33 and 34 having rectilinearity are provided at the front end portion 3a of the base 3 and both ends of the auxiliary base 4 without swinging, the direction in which the casters 33 and 34 move and the face plate 11 are arranged. The direction in which the force is applied in the description in (1) is orthogonal, and the board surface can be in a fixed state where it does not move as much as possible.

  Furthermore, since the weight 54 that lowers the center of gravity of the support body 2 is arranged at a low position of the upright portion 5, the support body 2 that has a T-shape in a plan view can be prevented from falling down and the self-supporting property can be further improved. .

  Furthermore, the intermediate frame 7 is provided with a lock mechanism 9 that releases the locked state by pulling the board 1 that has arrived at a predetermined position into the locked state and applying an operating force, thereby improving the stability when using the board. It can be easily released when it is used.

  Therefore, the board apparatus B of the present embodiment can be particularly suitable when applied to a lecture style such as active learning.

  As mentioned above, although one Embodiment of this invention was described, the specific structure of each part is not limited only to embodiment mentioned above.

  For example, in the above-described embodiment, the upper frame 6 is continuously connected to the upper end portion of the upright portion 5 by bending the upper end side of the first support column 51 and the upright portion of the second support column 52 is bent. The intermediate frame 7 is connected to the intermediate portion 5 in series, and as shown in FIG. 12, the first support column 51 and the second support column 52 are accommodated in the cover 55 to form the lower support 5A. The upper support 5B in which the upper frame 6, the upper vertical column 56 and the intermediate frame 7 are integrally formed by bending a round pipe may be attached. A horizontal attachment frame 57 serving as an attachment portion to the cover 55 is interposed between the upper vertical support 56 and the intermediate frame 7, and the intermediate frame 7 rises obliquely to the vicinity of the support shaft 22. In this example, the lower support 5A and the upper vertical support 56 constitute an upright portion of the present invention, and the recess 2a is formed at a position partially surrounded by the intermediate frame 7, the inner surface of the lower support 5A, and the base 3. It will be.

  In the above embodiment, the base and the auxiliary base are connected to form a T-shape in plan view. However, if the shape is a square shape in plan view, the independence can be improved within a range in which a seated person can easily approach. If it is made into the shape of a letter, independence can be improved, without disturbing the ease of putting in a leg space.

  Furthermore, in the said embodiment, although the transparent face plate was used for the board, even if it uses a white board, the effect according to the above is show | played.

  In addition, the dimensions and specific shapes of the respective parts are not limited to those in the illustrated embodiment, and various modifications can be made without departing from the spirit of the present invention.
