JP 2009-112695 A Japanese Patent No. 4349053

  As is apparent from Patent Documents 1 and 2, the cover that closes the wiring space has only a function of closing the space, and has no other functions. In other words, the wiring space is sized for convenience of wiring work, so if the wiring space is left open, articles placed on the desk may fall into the wiring space. Therefore, the cover is only provided with a function of closing the space.

  On the other hand, various stationery items are used when a person uses a desk. It is more convenient if the desk itself has the functions of these stationery items. The present invention has been made based on such an idea, and an object thereof is to provide a user-friendly desk and wiring space cover.

  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 relates to a desk, which is provided in a wiring space for drawing out cables on the peripheral edge of the top board, and a cover is disposed in the wiring space. An additional function part different from the function of closing the wiring space is provided on the cover.

  The invention of claim 2 embodies claim 1, and in this invention, the wiring space is provided in the top plate itself by forming a slit in a part of the periphery of the top plate, A cover receiver to which the cover is attached is provided on the inner periphery of the slit portion, while the cover is formed in a tray shape having a shallow concave portion as the additional function portion. Therefore, the cover includes a bottom plate and a peripheral wall. The cover can be attached to the cover receiver by selecting any of a posture in which the concave portion is opened downward and a posture in which the concave portion is opened upward.

  According to a third aspect of the present invention, the second aspect of the present invention is further embodied. In the present invention, an inner partition that divides the concave portion into a plurality of portions is provided in the concave portion of the cover. A fourth aspect of the present invention relates to a cover disposed in a wiring space provided at a peripheral portion of the top plate, and the wiring space cover is formed with a recess capable of storing articles on one side or both sides.

  Note that the additional function unit is not limited to a concave part that accommodates small items, and various configurations such as a pen stand hole in which a ballpoint pen can be inserted and a display board on which a photograph, a memo, and the like can be arranged can be adopted. .

  According to the present invention, since the cover for the wiring space can be used as stationery, the desk is easy to use. In addition, since the user can refrain from purchasing stationery, the user's economic burden can be reduced accordingly.

  Small items such as writing instruments and chip-type memories when using a desk can be said to be a must-have item. However, when configured as in claim 2, the cover for the wiring space can also be used as a small item storage tray, so that the desk can be cleaned. It is a useful treasure. In addition, since the cover can be placed in an attitude that opens downward, it is possible to refresh the desk surface when the cover is not used as a tray, and in this way it is possible to select properly depending on the user's request, Usability is particularly excellent.

  When the partition is provided in the recess as in the third aspect, it is excellent in the function of organizing small items when used as a tray, and therefore, the usability is further improved.

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 a steel plate can also be used. 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 cut-out portion 7 having a rectangular shape in plan view opened rearward is formed in the left and right intermediate portions of the rear end portion of the top plate 1, and the cut-out portion 7 forms a wiring passage. 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.

  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 7a of the slit portion 7 and the cover 8, there is an opening 7a for drawing the cable C onto the desk. As clearly shown in FIG. 9 (B), a pair of left and right partition portions 28 are provided to project rearward from the base portion 20 of the cover receiver 19 near the left and right ends. Is divided into three areas. 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. Moreover, it is also possible to form the engagement recessed part 36 and the engagement convex part 37 in the shape of a cone or a trapezoid. Further, the engaging recess 36 is an example of a female fitting part and the engaging convex part 37 is an example of a male fitting part. However, the cover 8 can be attached and detached and the front and rear position can be changed by other engaging means. It can be made rotatable. When the engaging concave portion 36 and the engaging convex portion 37 are formed in a spherical shape or a tapered shape, the attachment and detachment is facilitated due to the attraction effect.

  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 is the same size as the interval dimension W4 ″ between the engaging convex portion 37 and the partitioning portion 28 located in the foreground. Further, as shown in FIG. The distance dimension W5 with the engagement protrusion 37 on the side is set to be approximately the same as or slightly larger than the dimension W3 which is half 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 open at the top or bottom. For this reason, the cover 8 is suitable for the user's preference. Depending on the case, it can be used as a simple lid, used as an accessory case, or the use mode can be arbitrarily selected. In any state, since the engaging convex portion 37 and the engaging concave portion 38 are fitted with each other, the cover 8 is held in a stable state so as not to move when touched by a person.

  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 wiring channel | path between the cover 8 and the base 20 can be adjusted in two steps. Therefore, the area of the wiring path can be changed according to the amount of cables. For this reason, it is convenient.

  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 and rear engaging recess 36, it is possible to set the cover 8 so that it does not protrude behind the beam 6 in plan view. , W1 may be set to a size larger than W6. However, since desks are often arranged back to back, it can be said that W1 is preferably set to a size that is equal to or slightly smaller than W6 in order to avoid mutual interference.

  The cover 8 functions also as a bearing and the engaging convex portion 37, the engaging concave portion 36, and therefore the cover 8 flips up around a line O (see FIG. 5B) connecting the left and right engaging convex portions 37 positioned behind. Can be moved. 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). Other Embodiments FIG. 11 shows another embodiment which is another example of the cover. Among these, in the example shown in (A), the housing recesses are formed on both the front and back sides by arranging the bottom plate 14 of the cover 8 at a midway height (the depths of the two housing recesses are different). . By providing the partition 18 in the state of being close to one wall 16, it is possible to form a laterally long groove having a slight front-rear width, and this laterally elongated groove can be used for inserting cards. It is also possible to provide a plurality of intermediate partitions 18 and it is also possible to provide partitions that extend vertically and horizontally.

  In the example shown in (B), a pen stand hole 56 is provided as an example of the additional function unit. In this example, the pen stand hole 56 is provided on the side where there is no recess, but it is also possible to provide a pen stand portion in the opened portion. In the example shown in (C), a rotating lid plate 57 that closes the recess is provided. The lid plate 57 can also function as a display plate on which a memo is attached or a photograph is attached. In the example shown in (D), a shallow recess 59 is formed in the bottom plate 14, and the display plate 58 is mounted so as to be freely opened and closed. The display board 58 fits in the recess 59 when not in use.

(5). Others The present invention can be embodied in various ways other than the above embodiment. For example, as a means for providing a wiring space, it is not always necessary to cut out the top plate. By arranging a panel or a frame behind the top plate, it is possible to form a long wiring space on the left and right. Also, the cover can be embodied in various forms as required. Furthermore, the wiring space can be provided on the left side or the right side of the top plate. There are various types of desks (tables), but the present invention can be applied to various desks.

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