  A wiring space having an upper and lower opening is provided at the rear end portion of a desk, and cables are drawn out from the wiring space onto the desk. As a means for forming the wiring space, a case where the rear end portion of the top plate is partially cut out, and a back member such as a horizontally long panel or a beam is arranged behind the top plate, the top plate and the back member are arranged. In some cases, the space between them is used as a wiring space.

  In any case, the wiring space is usually covered with a cover, and an example of a desk cover in which the wiring space is formed by partially notching the rear part of the top plate as in the former is disclosed in Patent Literature 1. That is, in Patent Document 1, the cover is formed in a plate shape so as to be able to overlap the upper surface of the top plate, and the opening area can be adjusted by adjusting the front and rear positions of the cover.

JP 2009-112695 A

  In general, a large number of cables are drawn out on a desk, but the cables often get tangled with each other, and thus the appearance is not good. However, in a configuration in which the through-line portion is merely vacant behind the cover as in Patent Document 1, it cannot be expected that the cables are processed on the desk in a good manner.

  Further, in Patent Document 1, the wiring part for drawing out the cables on the desk is located at the cover, and the area of the wiring part is adjusted by sliding the cover back and forth. When the mounted cables are pulled, the cover may be pulled forward due to frictional resistance. As a result, there is a concern that the cover may be displaced and the opening area of the through-line portion may be widened.

  The present invention has been made to improve the current situation.

  In order to achieve the above object, the inventors of the present application have made the invention of each claim. Of these, the invention of claim 1 constitutes a superordinate concept. In the desk of this invention, a slit part that functions as a wiring space for drawing cables and the like is formed at the peripheral part of the top plate. Is a configuration that is closed with a cover leaving a part of the line part, and the line part is formed between a part of the inner periphery of the slit part and the cover, A partition part that divides the line part into a plurality of parts is provided in the line part.

  According to a second aspect of the present invention, in the first aspect, the partition portion is provided with a laterally extending portion extending substantially parallel to a part of the inner periphery of the slit portion, and a part of the inner periphery of the slit portion. A narrow portion for holding thin cables is formed between the laterally projecting portions.

  According to a third aspect of the present invention, in the first or second aspect, the inner periphery of the slit portion is provided with a resin cover receiver that overlaps the inner periphery, and the cover includes the partition. The partition part is slidably attached so as to move to and away from the part, and the partition part also functions as a stopper for regulating the movement position of the cover body.

  According to the invention of the present application, since the through-line portion for drawing the cable on the desk is divided into a plurality by the partitioning portion, the cable can be drawn on the desk in a state where a plurality of cables are stretched. For this reason, it is possible to prevent the cables from being hardened and to lay the cables on the desk with good appearance.

  The cables to be drawn on the desk vary from a thick one such as a power line to a thin one such as a communication line. The thin cable adopting the configuration of claim 2 is a thick cable through a narrow portion of the through-line portion. Since it can be divided, the sorting function (spreading function) can be further improved.

  When the cover is configured to be a slide type, there is an advantage that the opening area of the through-line portion can be changed according to the amount of cables, but when the configuration of claim 3 is adopted, the partition portion can function as a stopper for the cover. Therefore, the structure can be simplified accordingly. In addition, since the through-line portion is located on the inner side (the center side of the top plate) than the cover, there is no possibility that the cover is displaced by pulling the cable.

  Next, an embodiment of the present invention will be described with reference to the drawings. In the following description, the words “front and rear” and “left and right” are used to specify the direction, which is based on the direction of the person who uses the desk in a normal posture. Therefore, the frontage direction of the desk is the left-right direction, and the depth direction is the front-rear direction. For the front and back, the side closer to the user is used as the front, and the back part far from the user is used as the back.

(1). Outline of Desk As shown in FIGS. 1 to 3, the desk includes a square (rectangular) top plate 1 in plan view and left and right legs 2 that support the left and right sides. The top plate 1 is made of wood, but can be made of steel. The leg 2 has a gate shape in which rod-shaped front and rear leg supports 3 and 3 'are connected to each other by a horizontal upper frame 4 at the upper end, and a pair of front and rear spacers 5 are fixed to the upper frame 4 with bolts. The top plate 1 is fixed to 5 with bolts. Therefore, there is an interval between the top plate 1 and the upper frame 4 so that cables can be inserted.

  The leg posts 3 and 3 'and the upper frame 4 are hollow and have a substantially square shape, and are integrally connected via a connecting bracket having an L shape in side view and fitted into both. Further, a beam 6 is disposed between the upper portions of the rear leg struts 3 in the left and right legs 2, and the beam 6 and the left and right rear leg struts 3 are fixed with bolts. As a means for fixing the beam 6, a connecting bracket protrusion (not shown) that fits into the end of the beam 6 is fixed to the inner surface of the rear leg column 3, and the beam 6 is bolted to the connecting bracket protrusion. It is fixed with.

  A rectangular opening portion 7 in a plan view that opens backward is formed in the left and right intermediate portions of the rear end portion of the top plate 1, and the opening portion 7 forms a wiring space. A cover 8 is attached to the slit portion 7 to close it. The cover 8 is detachable. The rear part of the top plate 1 may be weakened due to the formation of the slit 7. In view of this, the left and right sides of the top plate 1 sandwiching the slit 7 are supported from below by a top plate support bracket 9 attached to the beam 6.

  A cable receiver 10 and a connector support 11 positioned above the cable receiver 10 are attached to the lower part of the beam 6. The cable receiver 10 is attached to the beam 6 so as to be slidable left and right. It is also possible to mount a plurality of cable receivers 10 on the beam 6.

  As shown in FIG. 3A, the beam 6 is connected to the upper end portion of the rear leg column 3 and substantially the latter half portion. As clearly shown in FIG. 4, the beam 6 includes a channel-shaped substrate 12 having upper and lower folded portions 12 a and 12 b protruding forward, and a convex reinforcement in a side view is formed on the front surface of the substrate 12. The material 13 is fixed by welding. The upper and lower folded portions 12a and 12b of the substrate 12 have rearwardly facing inward pieces 12a 'and 12b', respectively. Further, the reinforcing member 13 has a forward projecting portion 13a. In the beam 6, the reinforcing member 13 has a dovetail upper engaging groove 6a on both upper and lower sides sandwiching the forward projecting portion 13a. A lower engagement groove 6b is formed.

  The top plate support bracket 9 includes a fitting portion 9a that fits in the upper engagement groove 6a of the beam 6, a receiving portion 9b that is fixed to the lower surface of the top plate 1 with screws, and an inclined arm portion 9c that connects these portions. have. Half of the receiving portion 9b is exposed to the slit portion 7 in a plan view. Therefore, a substantially half portion is fixed to the top plate 1 in a plan view, and a substantially half portion in the plan view is below a cover receiver 19 described later. Are overlapping.

  The connector support 11 is a sheet metal product (may be made of resin), and is disposed between the arm portions 9 c of the left and right top plate support brackets 9. The connector support 11 has a main body 11a to which the outlet 11c can be fixed. A pair of left and right engaging pieces 11b that fit into the upper engaging groove 6a of the beam 6 are integrally formed at the upper end of the main body 11a. Yes.

  The engagement piece 11 b of the connector support 11 has a U-shape that is open downward when viewed from the side, and the tip of the engagement piece 11 b is fitted from above into a slit provided in the convex portion 13 a of the reinforcing member 13 that constitutes the beam 6. A portion of the fitting portion 9a of the top plate support bracket 9 that protrudes inward from the arm portion 9c overlaps with the engagement piece 11b of the connector support 11 from above. The cable receiver 10 has a tray-like shape that opens upward, and a fitting portion 10a that fits into the lower engaging groove 6b of the beam 6 is provided at the rear end thereof.

(2). Cover and its mounting structure The beam 6, top plate support bracket 9, cable receiver 10 and connector support 11 will be described later. First, the cover 8 and its mounting structure will be described with reference to FIGS. explain. The cover 8 is made of resin and has a shallow tray shape (box shape) so that small items can be accommodated therein, for example, as shown in FIG. That is, as an additional function portion, a recess for storing small items is provided.

  Therefore, the cover 8 has a bottom plate 14, a front wall 15, a rear wall 16, and left and right side walls 17. ing. The front wall 15, the rear wall 16 and the left and right side walls 17 constitute a peripheral wall. The cover 8 as a whole has a vertical dimension slightly thinner than the thickness of the top plate 1. Further, the partition 18 is lower than the walls 15, 16, and 17. Since the cover 8 of this embodiment has no front-rear directionality, there is no difference between the front and rear sides of the horizontally long wall, but for convenience, the one close to the partition 18 is called the rear wall 16.

  A cover receiver 19 for attaching the cover 8 is fixed to the slit 7 of the top plate 1. The cover receiver 19 is made of resin, and is formed in a U-shape in plan view having a plate-like base portion 20 and plate-like left and right side portions 21 so as to overlap the inner surface of the slit portion 7. A flange piece 22 that overlaps the upper surface of the top plate 1 is integrally provided at the upper ends of the base portion 20 and the side portion 21. The upper surface of the outer peripheral edge of the flange piece 22 is inclined toward the top plate 1. The cover 8 and the cover receiver 19 constitute a cover device.

  As shown in FIG. 9, a rectangular concave groove 32 is formed in the left and right intermediate portion of the inner bottom surface 7 a and the rear end portion of the inner side surface 7 b of the inner peripheral surface of the slit portion 7, while the base portion of the cover receiver 19 is formed. 20 and the side portion 21 are provided with fitting projections 31 that enter the concave grooves 32, and the concave grooves 32 and the fitting projections 31 are positioned, and the base portion 20 and the side portion 21 are screwed together. 25 is fixed to the slit 7.

  The base portion 20 of the cover receiver 19 directly overlaps the inner bottom surface 7 a of the slit portion 7, but an outward spacer piece 26 is provided on the side portion 21 of the cover receiver 19. It is in contact with the inner surface 7b. Therefore, there is a space between the side portion 21 of the cover receiver 19 and the inner side surface 7 b of the slit portion 7. For this reason, the side portion 21 is provided with a recessed portion 27 that contacts the inner surface 7 b of the slit portion 7, and the head of the screw 25 enters the recessed portion 27.

  Between the inner bottom surface of the cut-out portion 7 and the cover 8, a through-line portion for drawing the cable C onto the desk is opened. As clearly shown in FIG. 9 (B), a pair of left and right partition portions 28 project rearwardly from the base portion 20 of the cover receiver 19 near the left and right ends. It is divided into three areas on the left and right. Thereby, the cables C can be pulled out on the desk in a state where they are left and right. Note that the partition portion 28 also regulates the forward movement limit of the cover 8.

  The partition portion 28 is formed in an L shape in plan view having a laterally extending portion 28a. For this reason, the narrow portion 7c is formed between the laterally extending portion 28a and the base portion 20. A thin cable C such as a communication line can be passed through the narrow width portion 7c. As shown in FIG. 7, on the front surface of the laterally projecting portion 28a, a rib 29 having a triangular shape in a plan view is formed in which the front-rear width decreases toward the left and right outer sides. For this reason, the thin cable C can be sandwiched between the rib 29 and the base portion 20. In addition, the partition part 28 can also be made into T shape in planar view which has the laterally overhanging part 28a on either side.

  The partition portion 28 has a downward hanging piece 28b and is formed in a pocket shape, and the head of the screw 25 is disposed on the inner side surrounded by the hanging piece 28b. That is, the base portion 20 of the cover receiver 19 is fixed to the top plate 1 with screws 25 at the partition portion 28. A corner 30 having a triangular shape in plan view is provided at the lower end of the inner corner of the cover receiver 19. Auxiliary positioning projections 31 protrude from three portions of the base portion 20 of the cover receiver 19, that is, the left and right intermediate portions and the left and right end portions, and the end portions of the side portions 21. On the other hand, a positioning hole 32 into which the positioning protrusion 31 is fitted is formed in the inner surface of the slit portion 7.

  At the lower end of the side portion 21 of the cover receiver 19, a support piece 35 on which the left and right side portions of the cover 8 are placed protrudes inward. The support piece 35 does not extend the entire length of the side portion 21, and is disposed between the front end and the rear end of the side portion 21.

  While the cover 8 is supported by the support piece 35, the cover 8 can be freely changed to two positions in the front and rear directions, and can be flipped up and rotated around a horizontally long axis. Further, as described above, the cover receiver 19 is detachable.

  In this embodiment, the cover 8 can be easily understood from FIG. 8, FIG. 9 (B), and FIG. A pair of front and rear engaging recesses 36 are provided on the outer surface of the left and right side walls 17 of the cover 8, while the side portions 21 of the cover receiver 19 are selectively fitted into the pair of front and rear engaging recesses 36. A full engagement projection 37 is provided. The engaging concave part 36 and the engaging convex part 37 are formed in a curved surface so as to form a part of a sphere. For example, as shown in FIG. 9B, a laterally long recess (or rib) is formed in multiple stages on the outer surface of the left and right side walls 17 of the cover 8.

  The engaging recess 36 is provided at the tip of a cantilever-like tongue-shaped piece 38 positioned on both the front and rear sides of the recessed portion 27. That is, the tongue-like piece 38 is surrounded by the slit 39 except for its root, and the tongue-like piece 38 can be bent and deformed so that the engaging recess 36 moves left and right due to the elasticity of the resin. As described above, there is a space between the side portion 21 of the cover receiver 19 and the inner side surface 7 b of the slit portion 7, but the presence of this space causes the tongue-like piece 38 to escape from the cover 8. Large deformation is allowed.

  It is also possible to provide the engagement recess 36 on the cover 8 and the engagement projection 37 on the cover receiver 19. In addition, the engagement recess 36 and the engagement protrusion 37 are not limited to a curved surface structure. For example, the engagement protrusion 37 can be formed in a pin shape and the engagement recess 36 can be formed in a round hole. It is.

  As shown in FIG. 8, the front-rear distance W1 of the pair of engaging recesses 36 positioned in front and the front-rear distance W1 of the pair of engagement recesses 36 positioned rearward are set to the same size. The spacing dimension W2 of the engaging recess 36 and the spacing dimension W2 of the front and rear engaging projection 37 are the same. In addition, the fitting recess 36 is provided at the upper and lower intermediate height positions of the cover 8, and the dimension W3 from the upper and lower surfaces is the same as the vertical spacing dimension W3 ′ between the engagement convex part 37 and the support piece 35. Yes.

  Further, the distance dimension W4 between the engagement recess 36 located at the front and rear ends and the front and rear ends of the cover 8 is the same as the distance dimension W4 'between the rearward engagement protrusion 37 and the rear end of the side portion 21. At the same time, it has the same dimension as the interval dimension W4 ″ between the engaging convex portion 37 and the partitioning portion 28 located on the near side. Further, as shown in FIG. The distance dimension W5 with the rear engaging projection 37 is set to be approximately the same as or slightly larger than the dimension W3 which is half of the overall thickness dimension of the cover 8.

(3) Summary In the above-described configuration, as described above, the engaging protrusion 37 of the cover 8 can be engaged and disengaged by the tongue-shaped piece 38 being bent and deformed. For this reason, the cover 8 can be attached to and detached from the cover receiver 19 by bending and deforming the tongue-like piece 38. In this case, since W3 and W3 ′ have the same dimensions, the cover 8 can be attached to the cover receiver 19 even when the cover 8 is in an open position.

  Further, since W2 and W2 ′ are equal, the cover 8 is slid back and forth when a certain amount of force is applied, and the engaging convex portion 37 is selected and fitted to either of the front and rear engaging concave portions 36. Can do. Thereby, the space | interval of the through-wire parts 7a and 7c between the cover 8 and the top plate 1 (base part 20 of the receiving member 19) can be adjusted in two steps. In this case, since the cover 8 is supported by the left and right support pieces 35, the front and rear positions of the cover 8 are changed by changing the fitting positions of the male and female engaging portions 36 and 37. Can be moved back and forth.

  As shown in FIG. 5A, the rear end surface of the cover receiver 19 is shifted forward by a slight dimension W6 from the rear end surface of the beam 6. Therefore, by setting this dimension W6 to be substantially the same as the interval dimension W1 of the front-rear engaging recess 36, the cover 8 is set so as not to protrude behind the beam 6 in plan view. Although it is possible to set W1 to a size larger than W6, since desks are often arranged back to back, W1 is set to a size that is equal to or slightly smaller than W6 to avoid mutual interference. Is preferred.

  Since it also functions as the engaging convex portion 37, the engaging concave portion 36, and the bearing, the cover 8 is centered on a line O (see FIG. 5B and FIG. 6) connecting the left and right engaging convex portions 37 positioned rearward. Can be flipped up and turned. When wiring or checking the cable C, the cover 8 can be removed, but by turning up and turning, the opening portion 7 can be opened largely by one-touch operation without requiring force. Can do.

  When the cover receiver 19 is fastened to the top plate 1 with the screws 25 as in this embodiment, if the screws are fastened with the screws 25 at the partition portions 28 or the screws 25 at the recessed portions 27, Since the head of 25 is hidden in the concave portion, the cable C does not come into contact even if the head of the screw 25 is damaged and a burr comes out in the screwing operation, so that safety can be improved. In addition, since the cover 8 of this embodiment does not have the direction of front, back, left, right, and back, it can be arranged in any posture.

(4). Others The present invention can be embodied in various ways other than the above embodiment. For example, the wiring space can be provided on the left side or the right side of the top board. There are various types of desks (tables), but the present invention can be applied to various desks. In the illustrated embodiment, the right and left two partition portions are provided, but the number of the partition portions may be one or a plurality of three or more. It is also possible to form the partition part in a rib shape (fin shape), form a large number of them at appropriate intervals, and arrange one cable between adjacent ribs.

  In the above embodiment, the front / rear position of the cover is changed to two stages. However, in the case of a step adjustment type, the cover can be changed to a plurality of stages of three or more stages. Of course, the front and rear positions of the cover can be adjusted steplessly. Various mechanisms can be employed for the guide means for sliding the cover back and forth and the shaft support means for flipping up and turning the cover. Needless to say, the present invention can be applied to a type in which the cover is not slidable. Moreover, it is also possible to extend a partition part to the downward direction of a cover.

  The present invention can actually be embodied on a desk. Therefore, it can be used industrially.
