  In the configurations of Patent Document 1 and Patent Document 2, since the left and right columns are connected to the upper rear portion of the long and narrow base (grounding rod) before and after being separated from each other in the left and right direction, the bending moment is the largest due to the weight of the device on the mounting plate. The structure is such that it is difficult to increase the strength and rigidity of the connecting portion between the supporting column and the base. Therefore, when the heavy object is placed, the connecting portion may be deformed and the device on the placement plate may be inclined and unstable, or vibration may be generated when moving using a caster. In addition, when a person operates a personal computer or projector on a podium or projector stand, vibration may occur and the operability may be impaired depending on the magnitude and direction of the operation force. Furthermore, for example, in a podium, a speaker's bag or materials or equipment cannot be placed on the base.

  In the configuration of Patent Document 3, a base plate is provided. However, since the base plate is relatively thin, it is difficult to ensure sufficient strength and rigidity, and it is most bent by the weight of the device on the mounting plate. No consideration is given to the structure for increasing the strength and rigidity of the connecting portion between the support column and the base plate where the moment is applied.

  Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that a sufficient strength and rigidity can be secured at the connecting portion between the support column and the base, and a bag or a document or a device is placed on the base portion. The point is to provide a desk that can.

  In order to solve the above problems, the desk according to the present invention is a desk in which a support column is erected on the base portion and a mounting plate is supported by the support column, and the base plate that forms the upper surface of the base portion is provided. The rear horizontal plate, the front horizontal plate positioned lower forward than the rear horizontal plate, and the inclined plate connecting these horizontal plates and becoming higher toward the rear.

  Here, the rear horizontal plate is provided with an opening or a notch into which the lower end portion of the column is inserted, and a middle reinforcing member having a connection portion with the column and a substantially U-shaped reinforcing portion opened upward, It is preferable to attach to the lower surface of the horizontal plate, the inclined plate and the front horizontal plate.

  Further, the middle reinforcing member is fixed to the longitudinal reinforcing member extending in the lateral direction before and after the longitudinal reinforcing member, and the longitudinal reinforcing member extending in the longitudinal direction of the substantially U shape with the upper part opened in a front view. It is preferable that the front reinforcing member and the rear reinforcing member are used.

  Further, bent portions are formed by bending the front and rear ends of the base plate downward, and side reinforcing members that contact the front and rear bent portions are provided at the left and right ends of the rear horizontal plate, the inclined plate, and the front horizontal plate. It is preferable to be attached to the lower surface.

  Furthermore, it is preferable that rear casters are attached to the left and right sides of the rear reinforcing member, and smaller front casters than the rear caster are attached to the left and right sides of the front reinforcing member.

  According to the desk according to the present invention, a column is erected on the base portion, and the mounting plate is supported by the column, and the base plate that forms the upper surface of the base portion is a rear horizontal plate, Since it is formed by a front horizontal plate positioned lower forward than the rear horizontal plate and an inclined plate that connects these horizontal plates and becomes higher toward the rear, the base plate has such a shape. In particular, the torsional strength and torsional rigidity of the plate itself are increased. In addition, since the height of the rear part (rear horizontal plate) to which the support column is connected is increased, it is easy to make the structure to increase the strength and rigidity of the rear part of the base part, and as the rear left and right casters A large-diameter caster with a large allowable load can be used. In addition, a bag or a document or a device can be placed on the front horizontal plate, and the backward displacement of these items is regulated by the inclined plate. In addition, since the height of the front portion of the base portion is low, it is difficult for a shoe toe or the like to enter between the front end portion of the base plate and the floor surface. Since the horizontal plates before and after the base plate are connected by the inclined plate, the upper surface shape of the base plate provided with the step becomes smooth, and the appearance impression given to the viewer becomes clear.

  Further, the rear horizontal plate is provided with an opening or a notch into which the lower end portion of the column is inserted, and an intermediate reinforcing member having a connection portion with the column and a substantially U-shaped reinforcing portion opened upward is provided as the rear horizontal plate. If it is attached to the lower surface of the plate, the inclined plate, and the front horizontal plate, in addition to the above effects, the substantially U-shaped reinforcing portion that opens upward is integrated with the upper base plate, so that the strength of the base portion and Stiffness is improved. And since a support | pillar is directly connected to the connection part provided in the middle reinforcement member in the base part with such high intensity | strength and rigidity, the intensity | strength and rigidity of the connection part of a support | pillar and a base part improve.

  Further, the middle reinforcing member is fixed to the longitudinal reinforcing member, extending in the left-right direction before and after the vertical reinforcing member, and the longitudinal reinforcing member extending in the front-rear direction of a substantially U shape with the upper part opened in a front view. When the front reinforcing member and the rear reinforcing member are configured, in addition to the above effects, the substantially U-shaped longitudinal reinforcing member opened in the front-rear direction and the front reinforcing member and the rear reinforcing member extending in the left-right direction are integrated. Since the intermediate reinforcing member is integrated with the base plate on the upper side, the strength and rigidity of the base portion are further improved, and the strength and rigidity of the connecting portion between the support column and the base portion are further increased. improves.

  Furthermore, the left and right ends of the rear horizontal plate, the inclined plate, and the front horizontal plate are formed by forming side bent members formed by bending the front and rear ends of the base plate downward and contacting the front and rear bent portions. In addition to the above effects, the left and right side reinforcing members suppress the deformation of the base plate, so that the strength and rigidity of the base portion are further improved, and the strength of the connecting portion between the support column and the base portion. Further, the rigidity is further improved. In addition, the height of the front portion of the base portion is low, and a bent portion is formed at the front end of the base plate, so there is a toe of shoes between the front end portion of the base plate and the floor surface. It wo n’t get caught.

  In addition to attaching the rear casters to the left and right of the rear reinforcing member and attaching the front casters smaller than the rear caster to the left and right of the front reinforcing member, in addition to the above effects, the front reinforcing member having high strength and rigidity, and Since the front, rear, left and right casters are supported by the rear reinforcing member, the table can be moved more stably by these casters. In addition, since the caster is not exposed to the outside in the left-right direction of the base plate, there is no concern that people's clothes around the desk, such as trouser hems, will be soiled.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and all the embodiments that satisfy the requirements described in the claims are described.

  As shown in FIG. 1 and FIG. 2, the desk 1 has a support column 3 standing on a base portion 2, and supports placing plates 4 and 5 by the support column 3, and casters 11 ( The front casters 11F and 11F and the rear casters 11B and 11B) are attached, and can be easily moved by releasing the stoppers of the rear casters 11B and 11B. On the mounting plate 4 that is a top plate, for example, a notebook computer, a display, a document camera, or the like, or a lecturer's materials can be mounted. In front of the mounting plate 5 and the base plate 21 that are shelf plates. On the horizontal plate 23, for example, a main body of a desktop personal computer, a device such as a VTR, a DVD player, or a video printer, or a lecturer's bag or material can be placed. FIG. 2 shows a state in which the notebook personal computer PC is placed only on the placement plate 4 that is a top plate.

  Next, the structure of the support | pillar 3 and the base part 2 is demonstrated. As shown in FIGS. 3 and 4, the support column 3 has a structure in which left and right side support columns 32, 32 manufactured by, for example, extrusion molding of an aluminum alloy are attached to an intermediate support column 31 manufactured by, for example, sheet metal pressing of a steel plate. Thus, a lower end 3A attached to the middle reinforcing member 25 described later is formed. The base plate 21 includes a rear horizontal plate 22 in which an opening 22a (which may be a notch) into which the lower end 3A of the support column 3 is inserted, a front horizontal plate 23 positioned lower forward than the rear horizontal plate 22, And since it forms with the inclination board 24 which connects between these horizontal boards 22 and 23 and becomes high as it goes back, on the front horizontal board 23 which is the upper surface of the base part 2, an apparatus as above-mentioned or a bag, etc. Can be placed, and the inclined plate 24 restricts the backward displacement of the placed object. Further, as shown in FIGS. 1 and 2, the desk 1 having the base portion 2 having such a shape has a lower front portion of the base portion 2, and therefore the front end portion of the base plate 21 and the floor. Shoe toes are difficult to enter between the surface. And since the horizontal plates 23 and 22 before and after the base plate 21 are connected by the inclined plate 24, the upper surface shape of the base plate 21 provided with the step becomes smooth, and the impression of appearance given to the viewer is clear. It becomes that.

  Such a shape of the base plate 21 increases the torsional strength and torsional rigidity of the base plate 21 itself. In addition, since the height of the rear portion (rear horizontal plate 22) of the base portion 2 to which the support column 3 is connected is increased, it is easy to make a structure that increases the strength and rigidity of the rear portion of the base portion 2, and the rear portion. A large-diameter caster having a large allowable load can be used as the casters 11B and 11B. In addition, without forming the opening 22a in the rear horizontal plate 22, the support column 3 can be attached to the base plate 21 directly or via another component.

  In the present embodiment, as shown in FIG. 3, the middle reinforcing member 25 is formed in a substantially U-shaped longitudinal reinforcing member 26 that opens upward in front view, and before and after the longitudinal reinforcing member 26. The front reinforcing member 28 and the rear reinforcing member 27 extend in the left-right direction and are fixed to the vertical reinforcing member 26.

  The vertical reinforcing member 26 is a rectangular lower plate 26D that is long in a substantially horizontal front-rear direction, left and right side plates 26S, 26S standing up from the left and right ends of the lower plate 26D, and upward from rear ends of the left and right side plates 26S, 26S. The left and right rear plates 26B and 26B extend. Engagement holes 26c and 26c are formed at the left and right of the rear part of the lower plate 26D, and the vertical slits 26a and 26a and the vertical slit 26b are provided at the rear and front parts of the left and right side plates 26S and 26S, respectively. , 26b are formed.

  The rear reinforcing member 27 is composed of a rectangular upper plate 27U formed with an opening 27a and a front plate 27F and a rear plate 27B hanging from the front and rear ends of the upper plate 27U. The front plate 27F is formed with vertical slits 27b and 27b on the left and right sides thereof, and engaging protrusions 27c and 27c project from the slits 27b and 27b.

  Here, the base plate 21, the vertical reinforcing member 26, the rear reinforcing member 27, and the front reinforcing member 28 having the above-described shape are manufactured by, for example, sheet metal pressing of a steel plate. Note that a side surface portion may be formed on the side surface of the base plate 21 by bending or drawing, and the strength and rigidity are further enhanced by such a side surface portion.

  The rear plates 26B and 26B of the vertical reinforcing member 26 are inserted into the openings 27a of the rear reinforcing member 27 from the lower side, the slits 27b and 27b are engaged with the slits 26a and 26a, and the engagement protrusions 26c and 26c are engaged. When the pieces 27c, 27c are engaged, the rear reinforcing member 27 is positioned with respect to the vertical reinforcing member 26 as shown in FIG. Further, when the slits 28 a and 28 a of the front reinforcing member 28 are engaged with the slits 26 b and 26 b of the vertical reinforcing member 26, the state shown in FIG. 4 is obtained in which the front reinforcing member 28 is positioned with respect to the vertical reinforcing member 26. . If the longitudinal reinforcing member 26, the rear reinforcing member 27, and the front reinforcing member 28 are welded in this state, they are firmly connected and integrated into the middle reinforcing member 25.

  Further, the front casters 11F and 11F and the rear casters 11B and 11B are attached to the left and right of the front reinforcing member 28 and the rear reinforcing member 27 of the middle reinforcing member 25 that are firmly connected and have high strength and rigidity (casters). (See Fig. 1 and Fig. 2 for the external appearance of which is attached). Therefore, since the front and rear, left and right casters 11F and 11F and the rear casters 11B and 11B are supported by the reinforcing member having high strength and rigidity, the table 1 can be moved more stably by these casters. In addition, since the casters 11F and 11F and the rear casters 11B and 11B are not exposed to the outside of the base plate 21 in the left-right direction, there is no fear that people's clothes around the desk, for example, trousers' hems, etc. will be soiled.

  Here, the front casters 11F, 11F can be easily attached using the engagement holes 28b,... (Formed in the front plate 28F and the rear plate 28B) of the front reinforcing member 28 shown in FIG. The casters 11B and 11B can be easily attached using the screw holes 27f of the rear reinforcing member 27 shown in FIG. Since the rear casters 11B and 11B are provided with stoppers and the rear casters 11B and 11B do not swing and rotate, the stationary state of the desk 1 is maintained. Since the rear casters 11B and 11B do not swing and rotate, boss portions are provided on the left and right sides of the rear reinforcing member 27, and the left and right axles are supported by the boss portions.
