Description

  The present invention is a table in which a plurality of tables are used by abutting and assembling their top plates, and the function of inserting wiring from the bottom to the top plate or from the top to the bottom is attached to the top plate and the legs. The present invention relates to a wiring structure in a table attached to a structure portion, and a bracket interposed between a top plate and a leg to realize the wiring structure. In the present invention, the table is used as a concept including a desk having a top plate and a rod-like leg.

  The structure for guiding the power line and communication line of the personal computer used on the table top to the top from the bottom of the top, or in the opposite direction, is a groove formed on the top. In many cases, a wiring duct such as a bowl is provided below the wiring opening.

  On the other hand, a table in which wiring can be introduced and led out between the upper and lower surfaces of the top board without providing wiring openings or wiring ducts on the top board is also known from Patent Documents 1 and 2, for example.

In the table proposed by Patent Documents 1 and 2 and the like in which the wiring opening or wiring duct is not provided on the top plate, the outer shape of the top plate (outer periphery) is used to insert the wiring between the top and bottom surfaces of the top plate. The shape is deformed, and wiring is derived and introduced from the deformed part.
That is, in the techniques disclosed in Patent Documents 1 and 2, when the deformed top plates are brought into contact with each other, the top plate is so formed that an opening or a notch for wiring insertion is formed by the peripheral portions of the deformed shapes. A part of the outer periphery is formed into a shallow concave shape, or a substantially 1/4 arc-shaped cutout is formed at the corner of the top plate.

However, forming the outer shape of the top plate in a different shape as in the above example has the problem of increasing the cost of the top plate due to the extra work required for the preparation of the top plate. There is a problem that the writing instrument etc. falls from the notch to the bottom of the top plate, and there is also a problem that when the table is used alone without being assembled, the shape of the deformed outer shape part feels strange. .

The bracket having the upper end portion of the leg coupled to the leg coupling portion is attached so that the outer periphery of the leg is inscribed in the straight side of the top plate corner or slightly inward.
With this mounting mode, when the rounded corner is attached to the top plate corner, the outer circumference of the leg may protrude outside the rounded corner of the top plate. The outer periphery of the entire flat section is always inscribed in the straight side of the top plate or slightly inside, so even if the top plates of two or more tables are brought together to meet each other, adjacent tables The legs do not interfere with each other.

  The present invention relates to a table having rod-shaped legs at the four corners of the bottom surface of the top plate, a table having rod-shaped legs at the four corners of the bottom surface of the top plate, and a table having rod-shaped legs at the four corners of the bottom surface of the top plate. An outer periphery of the leg is positioned on the inner side of the straight side of the top plate located at the corner of the plate, and is used for supporting the top plate for connecting the leg and the top plate between the upper end of the leg and the lower surface of the top plate. Since the bracket is provided, the joint portion of the bracket with the upper end of the leg is formed narrower than the upper end of the leg, and the wiring is passed between the thinly formed portion and the top and bottom surfaces of the top plate. Even if the top plate is not provided with a wiring duct, the wiring insertion function can be provided without providing a recessed portion or a notch portion for passing the wiring around the outer periphery of the top plate.

  In addition, the wiring insertion function includes the top plate support plate portion whose upper surface is in contact with and fixed to the lower surface of the top plate, and one end side thereof is integrally provided on the lower surface side of the plate portion and the other end side is the outer shape of the plate portion. An arm part formed so as to protrude from the leg part, and a leg joint part formed at the tip part of the arm part and coupled to the upper end of the leg. It is obtained by a bracket for supporting the top plate formed so as to be located on the inner side.

  Next, an example of an embodiment of the wiring structure of the present invention and an example of an embodiment of a bracket for the same will be described with reference to the drawings.

  FIG. 1 is a plan view of a main part of an example in which four tables to which the wiring structure of the present invention is applied are assembled in a table top butting state, and FIG. 2 is an enlarged perspective view of one table used in FIG. 3 is a plan view of the main part of the table of FIG. 2, FIG. 4 is a front view of the main part of the table of FIG. 3 with the height of the legs omitted, and FIG. 5 is a perspective view of an example of the bracket of the present invention. 6 is a perspective view of another example of the bracket of the present invention.

  In the figure, 1 is a top plate having a planar rectangular shape on a table, 1a and 1b are straight sides of the top plate 1, 1c is two corners with rounded corners where both straight sides 1a and 1b are orthogonal, In, the corner for the corner of the general top plate is attached. In the present invention, the corners with rounded corners may be any one of 1 to 4, and the corners may not be rounded. In FIG. 1, reference numeral 1 d denotes two right-angled corners formed at the intersection of the long straight side 1 a ′ parallel to the straight side 1 a and the short straight side 1 b without a rounded corner. The number of right-angled corners when the top corners are rounded is determined by the number of corners with rounded corners, but when all corners are not rounded, the four corners become right-angled corners. Here, four legs 5 having a circular cross section are provided at the four corners of the top plate 1 in FIG. 1 so that the outer periphery of the legs does not protrude from the straight side near the corner of the top plate. Yes. This point will be described later.

  In the example shown in the figure, four rounded columnar legs 5 are attached to the top plate support bracket 3 (hereinafter simply referred to as the top plate 1). It is attached to the four corners of the top plate lower surface 2 via the bracket 3 (see FIG. 1). At this time, the outer diameter of the flat cross section of each leg 5 (the contour of the largest diameter portion) is set at a position inscribed in the intersection of the straight sides 1a and 1b and 1a 'and 1b of the top plate 1. In addition, although the said inscribed is the meaning of the inscribed in geometry, it is used in the meaning including a manufacturing limit or tolerance.

  As illustrated in the perspective views of FIGS. 5 and 6, the bracket 3 has a substantially rectangular shape in which a screw hole 31 a is provided in surface contact with the lower surface 2 of the top plate 1 and fixed to the top plate with screws 4 or the like. The top plate support plate portion 31, the arm portion 32 formed on the lower surface side of the plate portion 31, here in a direction crossing the plate portion 31 diagonally (diagonal line), and the tip side of the arm portion 32 A leg connecting portion 33 is formed so as to protrude from the outer peripheral edge on the front end side of the plate portion 31 and to which a leg 5 described later is connected to the lower end side of the protruding end at the upper end of the leg 5.

  In the bracket 3 of FIG. 5, a frame receiving seat 34 is formed on the rear end side of the bracket for coupling and fixing the end portion of the top plate frame 6 attached to the top plate lower surface 2. The bracket 3 of FIG. 6 is a bracket for a small top plate where the top plate frame 6 is not provided. Accordingly, the bracket 3 of FIG. The planar shape of the plate portion 31 may be a polygon other than the above example, or a circular shape or a similar shape. Further, the leg coupling portion 33 formed at the distal end of the arm portion 32 is formed such that the outer diameter of the distal end portion 33a on the outer surface side is smaller (smaller than the outer diameter of the leg upper end portion 5a).

  The frame receiving seat 34 illustrated in FIG. 3 and FIG. 5 is disposed at an angle difference of 90 degrees with respect to the bracket 3 (in other words, disposed parallel to the straight side of the top plate 1). Although formed as a receiving seat 34 for receiving the top frame 6, the frame receiving seat 34 in the bracket 3 of the present invention is not limited to the above example. For example, receiving and attaching the orthogonal parts of the two top plate frames 6 and 6 (top plate frames 6 and 6 arranged in parallel to the straight sides 1a and 1b) arranged in the direction orthogonal to the bracket 3 Some are made so that they can. Reference numeral 7 denotes a positioning pin of the top frame 6 projecting from the seat 34 (see FIG. 3).

In the bracket 3 of the present invention, on the back surface 2 of the corners 1c and 1d of the top plate 1, the arm portion 32 of the top plate support plate 31 is 45 with respect to the straight sides 1a and 1b of the corner 1c. A top plate support plate 31 is attached to the back surface 2 of the top plate 1 by screws 4 or the like so as to be oriented at an angle of degrees.
In addition, the bracket 3 attached to the top-plate back surface 2 precedes the process which couple | bonds and attaches the upper end of the leg 5 to the leg coupling | bond part 33 before attaching to the top-plate lower surface 2 for the convenience of an assembly process.

  As described above, the four legs 5 attached to the insides of the corners 1c, 1d on the back surface 2 of the top plate 2 via the bracket 3 are located above the upper end surface 5a, and from the outer diameter of the legs 5. A gap g is formed by the tip 33a of the small-diameter arm 33.

By forming the gap g between the lower surface 2 of the top plate 1 and the upper end surface of the leg 5, the gap g is interposed between the top plate lower surface 2 side and the upper surface side of the top plate 1. The wiring W can be introduced and derived (refer to the wiring W indicated by a one-dot chain line in FIGS. 2 and 4).
Therefore, when the table according to the present invention having the above-described configuration for inserting the wiring is arranged by abutting the right-angled corners as shown in FIG. 1, all the contact lines of the four top plates are in close contact with each other. It can be used like a table with a single top plate, and still has a function that allows wiring to be inserted between the top and bottom of the top plate.
On the other hand, when the four top plates shown in FIG. 1 are arranged by replacing the left and right top plates 1 and 1 with the left and right top plates 1 and 1, the four top plates 1 are assembled. Since the rounded corners of each top plate 1 are gathered at the center, wiring can be inserted between the top and bottom of the top plate from the center of the four gathered top plates 1.
It should be noted that the wiring W that is raised from the floor along the legs 5 can realize a wiring that does not get in the way when held by a wiring clip (not shown) attached to the legs 5.

  The present invention is as described above, and in a table having rod-like legs at the four corners of the top plate lower surface, the outer periphery of the legs is positioned inside the top plate straight side located at the corner of the top plate, A bracket for supporting the top plate for connecting the leg and the top plate is provided between the upper end of the leg and the lower surface of the top plate, and a joining portion of the bracket with the upper end of the leg is formed narrower than the upper end portion of the leg. While forming the wiring structure of the table, the top plate supporting plate portion whose upper surface is in contact with and fixed to the back surface of the top plate, and one end side thereof are integrally provided on the lower surface side of the plate portion and the other end An arm portion formed so that a side protrudes from the outer shape of the plate portion, and a leg coupling portion formed at a tip portion of the arm portion and coupled to an upper end of the leg, and an outer planar outer shape of the leg coupling portion Is inside the cross-sectional outline of the leg Since it is achieved by the bracket formed so as to be positioned, there is no wiring opening or wiring duct in the center of the top plate, and there is a recess or notch for passing the wiring around the outside of the top plate. Even if it is not provided, in other words, even if it is a normal rectangular top board that does not have the special configuration for wiring, the wiring is passed between the top board and the floor side (under the top board) in a good manner. A special effect is possible.

  In particular, there is no wiring opening or wiring duct on the top plate, and there are no wiring recesses or cutouts on the outer periphery of the top plate, so not only can the manufacturing cost of the top plate be significantly reduced. Thus, there is an advantage that the top plate can be manufactured easily and at low cost.

  Further, according to the present invention, four legs are provided at the four corners of the top plate (at the corner where the top plate straight sides intersect, or in the vicinity of the straight side, or in the vicinity thereof). Since the outer periphery of the leg is provided at a position where the outer periphery of the leg does not protrude from the straight side (a position inscribed in the vicinity of the straight side or in the vicinity of the inscribed position) at the intersection (corner) of the straight side of the top plate, 2 Even if the table above the table is put together with the top plates butted together, the legs of the adjacent tables do not interfere with each other and the wiring can be passed between the top and bottom of the top plate in this state. The effect is obtained.
