  By the way, the situation is the same in that it is effective to improve the convenience of the wiring process even in furniture with a top plate such as a table provided with a caster at the lower end portion of the leg column and movable.

  However, there is a situation different from that of a leg having a conventional structure in order to pass wiring through such a leg column with casters. For example, if the furniture with a top plate is moved while the wiring is passed through the legs, the casters and the wiring are entangled and there is a risk of not being able to move smoothly but also disconnecting. In addition, when the wiring groove pulls the wiring, an electric / electronic device such as a PC placed on the top board and connected to the wiring falls on the floor, or the wiring is also disconnected by the wiring groove. There is a danger of. Therefore, in order to provide a wiring groove using a leg column with casters, a device that is not present in the conventional leg column including the wiring groove is required.

  An object of this invention is to provide the leg of the structure which solves such a subject, and the furniture with a top plate using the same.

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

That is, the leg having the intra-leg wiring structure according to the first aspect of the present invention is provided with a caster on the lower end side of the leg support, and the leg support includes a support main body having a caster attaching portion at the lower end. A wiring groove starting from a position displaced from the caster mounting portion by a predetermined distance above the caster body and extending to the upper end of the pillar body, and a cover removable from the wiring groove, is attached to casters caster mounting portion, said post body respectively to open the wire entrance to the upper and lower ends of the wiring groove in a state of mounting the cover on and Ri Na, near the opening of the wiring entrance of the lower end side, wiring An inclined or curved guide portion for guiding the wiring in the groove in a direction different from the longitudinal direction of the leg support is provided .

In addition, there is an inclined or curved guide section that guides the wiring in the wiring groove in a direction different from the longitudinal direction of the leg support near the opening of the wiring entrance on the lower end side, so that the wiring does not face the caster. You can also guide.

In order to provide a more appropriate guide for the wiring, it is desirable that the inclination direction of the guide portion or the tangential direction at the opening end is set so as not to intersect the operation space necessary for swinging the caster.

Further, in order to improve the strength of the leg struts and to organize the internal wiring, it is preferable that a longitudinal rib extending along the longitudinal direction of the strut body is formed in the central portion of the wiring groove in the groove width direction.

The leg having the intra-leg wiring structure of the second invention in the present application is provided with a caster on the lower end side of the leg strut, and the leg strut has a column main body having a caster attaching portion at the lower end, A wiring groove starting from a position displaced from the caster mounting portion by a predetermined distance in the column main body and extending to an upper end of the column main body, and a cover removable from the wiring groove; A caster is attached to the section, and a wiring inlet / outlet is opened at each of the upper end and lower end of the wiring groove with the cover attached to the column main body. A vertical rib extending along the longitudinal direction is formed. In this way, in the legs equipped with casters, if a wiring groove is provided above the caster mounting portion and the wiring inlet / outlet is opened at the upper end and lower end of the wiring groove, wiring is performed so as not to interfere with the caster. Can be routed. Furthermore, since the vertical rib extending along the longitudinal direction of the column main body is formed in the central portion of the wiring groove in the groove width direction, the internal wiring arrangement can be performed while improving the strength of the leg column.

In order to further improve the strength of the leg strut without impairing the wiring function, a lateral rib that intersects the longitudinal direction is provided at an intermittent position along the longitudinal direction of the strut body, and a part of the lateral rib is cut. It is desirable that the groove bottom of the wiring groove is formed.

The leg having the in-leg wiring structure of the third invention in the present application is provided with a caster on the lower end side of the leg support, and the leg support has a support body having a caster mounting portion at the lower end, A wiring groove starting from a position displaced from the caster mounting portion by a predetermined distance in the column main body and extending to an upper end of the column main body, and a cover removable from the wiring groove; At the same time, the caster is attached to the section, and with the cover attached to the column main body, the upper and lower ends of the wiring groove are opened with the wiring entrances, and the wiring groove and the cover are tapered toward the bottom. It is characterized in that the side edge of the cover and the corresponding opening edge of the column main body can be brought into close contact with each other by finely moving the cover downward with respect to the wiring groove. In this way, in the legs equipped with casters, if a wiring groove is provided above the caster mounting portion and the wiring inlet / outlet is opened at the upper end and lower end of the wiring groove, wiring is performed so as not to interfere with the caster. Can be routed. Furthermore, the wiring groove and the cover are tapered downward, and the cover is slightly moved downward with respect to the wiring groove after mounting, so that the side edge of the cover and the corresponding opening edge of the column main body can be brought into close contact with each other. Therefore, a neat appearance can be ensured with the cover mounted.

In order to effectively improve the convenience of the wiring process, the engaged portion is set on the column main body, while the engaged portion engaged with the engaged portion is pressed by pressing the cover in the direction of closing the wiring groove. And the engagement state between the engaging portion and the engaged portion is released when a peeling force in the direction opposite to the pressing direction acts on the cover. Is effective.

In order to store the wiring effectively, simplify the peeling of the cover, and prevent the wiring from being stressed, the upper and lower ends of the wiring groove of the column body and the upper and lower ends of the cover in the longitudinal direction It is effective to form a wiring entrance between them.

To prevent stress from being applied to the wiring regardless of the direction in which the wiring is led in / out, at least the wiring inlet / outlet on the lower end side is substantially circular between the end of the wiring groove and the end of the cover in the longitudinal direction. It is also convenient that it is formed.

In order to effectively realize a specific detaching structure between the cover and the wiring groove while securing a wiring space between the left and right elastic claws, the engaging portion is directed from the left and right edges of the cover toward the wiring groove. And the engaged portion is a recess provided at the left and right corresponding positions on the inner surface of the wiring groove, and the left and right elastic claws are engaged with the recess by an elastic force in a direction away from each other. In other words, it is effective that the engagement with the recess is released by elastic deformation in a direction close to each other.

To attach to the wiring groove with the wiring hooked on the cover and the wiring not protruding from the cover, use the engagement part of the cover and wire the cable before attaching the cover to the column body. It is appropriate to configure a restricting portion that restricts the cover from protruding sideways from the side edge of the cover.

  If the furniture with a top plate is configured by supporting the top plate with three or more legs as described above, even if the furniture with the top plate is basically a simple structure with only the top plate and the legs, the wiring function Can be effectively provided.

  Since the present invention has the configuration described above, a wiring groove is provided above the caster mounting portion, and a wiring inlet / outlet is opened at the upper end portion and the lower end portion of the wiring groove so that the wiring is not disturbed by the caster. Can be routed. As a result, when the furniture with the top plate is moved while the wiring is passed through the legs, the caster and the wiring are not tangled. In addition, by pulling the wiring, it is possible to reduce the risk that an electric / electronic device such as a PC placed on the top plate falls on the floor or the wiring is disconnected.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a total of four legs B having the intra-leg wiring structure of this embodiment are arranged at positions that support the bottom surfaces of the four corners of the top board A, and constitute a furniture T with a top board such as a table. .

  A leg support bracket A1 is provided on the lower surface of the four corners of the top plate A, and each leg B is fixed to the leg support bracket A1.

  Each leg B is comprised by the leg support | pillar 1, the cover 2, and the caster 3, as shown in FIGS.

  As shown in FIG. 2A, the leg support 1 is mainly composed of a support body 11 made of aluminum die cast, and the support body 11 has a generally tapered shape as a whole vertically downward. The caster mounting portion 11b is set on the lower end portion 1b of the leg support 1, and the upper end portion 1a of the leg support 1 is provided with a leg receiving bracket mounting portion 11e slightly protruding toward the wiring groove 12 side. It has been. And the wiring groove | channel 12 is formed in order to implement | achieve the wiring structure in a leg.

  The wiring groove 12 starts from a position Q displaced upward by a predetermined distance from the caster mounting portion 11b, extends to a position P of the upper end portion 11a of the column body 11, and has a tapered shape from above to below. It is provided in a state in which the contents of the main body 11 are surrounded.

  As shown in FIG. 3, an inclined guide portion 121 that guides the wiring X in the wiring space 12 x in a direction different from the longitudinal direction of the leg support 1 is provided near the lower end portion 12 b of the wiring groove 12. The inclination direction C of the guide portion 121 is set so as not to intersect with the space Y necessary for the swinging motion of the caster 2, and the opening end has a substantially semicircular shape.

  As shown in FIG. 4, vertical ribs 122 are longitudinally cut in the center of the wiring groove 12 in the groove width direction, and intersect with the vertical ribs 122 at intermittent positions along the longitudinal direction of the column main body 11. The lateral rib 123 crosses. The lateral rib 123 has the wiring space 12x secured above the groove bottom 123a by cutting out part of the edge on the side where the wiring space 12x is open. In this case, the wiring space 12x is divided into two sides on both sides of the vertical rib 122 so that the wiring X can be divided.

  Further, the inner surface 12y of the left and right side edges 11c and 11d of the column main body 11 is provided with a recess 124 which is an engaged portion in a rectangular shape at an intermittent position along the longitudinal direction. More specifically, the recesses 124 are provided at a total of four locations, one in the vicinity of the upper and lower ends of the wiring groove 12 and two in the longitudinal middle portion of the wiring groove 12. Assuming that the direction of mold release during molding of the leg support 1 is the direction in which the cover 2 is attached / detached, in order to provide the recess 124, it is usual to use a slide mold. The height of the rib 122 is suppressed so as to be inward of the recess 124, and a margin for inserting a rotary blade for cutting the recess 124 in the wiring space 12x is secured.

  On the other hand, as shown in FIG. 2B, the cover 2 is a resin molded body that extends along the wiring groove 12 and tapers downward as a whole. A cover rib 21 is formed at the center of the cover 2. The upper and lower ends 22a and 22b of the cover 2 have a substantially semicircular shape toward the center of the cover. An elastic claw 24 as an engaging portion protrudes from the side edges 2a and 2b of the cover 2 toward the side edges 11c and 11d of the column main body 11, and is configured to engage with the recess 124. .

  As shown in FIG. 5A, the claw portion 24 a of the elastic claw 24 that engages with the recess 124 is slightly inclined with respect to the inner wall 124 a of the recess 124. When the cover 2 is attached to the wiring groove 12, the nail 24 is restored after being elastically deformed in the direction in which the elastic claw 24 temporarily approaches in the order of FIG. 5 (c) → (b) → (a). When the portion 24a is engaged with the recess 124 so as to be along the inner wall 124a and the cover 2 is peeled off from the wiring groove 12, it is elastic in the order of FIG. 5 (a) → (b) → (c). When the claw 24 is temporarily elastically deformed in the direction in which the claw 24 approaches, the claw portion 24a is detached from the inner wall 124a, so that the engaged state between the elastic claw 24 and the recess 124 is released. In this embodiment, the vertical dimension of the recess 124 is set slightly larger than the vertical dimension of the elastic claw 24.

  The space between the left and right elastic claws 24, 24 can also be used as the wiring space Z when the cover 2 is closed as shown in FIG. The elastic claw 24 serves as a restricting portion 25 that restricts the wiring X from protruding laterally from the side edges 2a and 2b of the cover 2 in the state shown in FIG. 9 before the cover 2 is attached to the column main body 11. It also plays a role.

  After the cover 2 is mounted in the wiring groove 12, as shown in FIG. 6, the wiring entrances 4 and 5 are configured at positions where the upper and lower ends 12a and 12b of the wiring groove 12 and the upper and lower ends 22a and 22b of the cover face each other. Is done. In particular, the wiring entrance / exit 5 on the lower end side has a substantially circular shape when viewed from the horizontal direction indicated by an arrow V in the drawing.

  As shown in FIGS. 3 and 7, the caster 3 includes a caster body 31, a wheel 32, and a caster mounting shaft 33, and is attached to the caster mounting portion 11 b of the leg column 1.

  The caster mounting portion 11b includes a cylinder 11f that opens at the lower end. A spring 11e is incorporated in the cylinder 11f at a position compressed by the caster mounting shaft 33, and a damper action is applied to the caster 3 between the immersion position and the protruding position. Can be run. The caster 3 is rotatable about the caster mounting shaft 33 as a rotation center.

  As shown in FIG. 8, a fishhook-like hook 6 is attached with a screw 61 in the vicinity of the wiring inlet / outlet 4 on the back surface of the leg receiving bracket A <b> 1, and the wiring X drawn out from the wiring inlet / outlet 4 is hooked on the hook 6. Thus, the convenience of organizing the wiring X is ensured.

  Next, the use state of this embodiment will be described. As shown in FIG. 9, the user holds the cover 2 in a state in which the wiring X is pulled out from the upper and lower end portions 22 a and 22 b of the cover 2 while applying the wiring X to the back surface 2 c of the cover 2 with a finger not shown. Then, the cover 2 is fitted into the opening of the wiring groove 12 and the cover 2 is pressed toward the wiring groove 12 as indicated by an arrow W in FIG. At this time, the elastic claw 24 and the recess 124 are engaged as shown in FIGS. For excessive push-in, the cover rib 21 abuts against the vertical rib 122 of the column main body 11 and further push-in is restricted, so that the cover 2 is not damaged or improperly fitted. Since the vertical dimension of the recess 124 is set to be slightly larger than the vertical dimension of the elastic claw 24 as described above, even if the recess 124 fits slightly above the recess 124, the cover 2 is left as it is. As shown in FIGS. 11A to 11B, the cover side edges 2a and 2b and the corresponding opening edges 12c and 12d of the wiring groove 12 are brought into close contact with each other. In this state, as shown in FIG. 10, the wiring X can be hidden by the length of the cover 2.

  As shown in FIG. 1 and FIG. 12, for example, if the wiring X is a power cable, the user can connect the power connector X1 at the tip of the wiring X to the outlet D1 provided on the wall D. When trying to move the furniture T with the top plate, the wiring X is caught by the wiring entrance / exit 5 of the cover 2, and the peeling force F in the direction opposite to the pressing direction described above is applied to the lower end 22 b of the cover 2. By acting against the cover 2, the cover 2 comes off the wiring groove 12. In particular, one of the engaging portions of the elastic claw 24 and the recess 124 is in the vicinity of the lower end portion 22b of the cover 2, and the cover 2 can be peeled relatively easily even from the engaging structure. Become. Of course, even if a finger is inserted into the wiring entrance 5 and the lower end 22b of the cover 2 is pulled forward, the cover 2 can be easily peeled off. These circumstances are substantially the same on the upper end portion 22a side of the cover 2.

  As described above, the leg B of the present embodiment is provided with the caster 3 on the lower end side of the leg column 1, and the leg column 1 includes the column main body 11 having the caster mounting portion 11 b at the lower end portion 1 a. The wiring groove 12 starting from a position Q of the column main body 11 displaced upward by a predetermined distance from the caster mounting portion 11b and extending to the position P of the upper end portion 11b of the column main body 11 and the wiring groove 12 The caster 3 is attached to the caster attaching part 11b, and the upper and lower ends 12a and 12b of the wiring groove 12 are connected to the entrances and exits, respectively, with the caster 3 attached to the caster attaching part 11b. Since the openings 4 and 5 are opened, the wiring X can be routed so as not to interfere with the caster 2.

  In this case, an inclined guide portion 121 that guides the wiring X in the wiring groove 12x in a direction different from the longitudinal direction of the leg support 1 is provided near the opening of the wiring entrance 5 on the lower end side. It can be guided not to go to.

  In particular, since the inclination direction C of the guide portion 121 is set so as not to intersect with the operation space Y necessary for swinging the caster 3, a more appropriate guide can be provided for the wiring X.

  In addition, a recess 124 that is an engaged portion is set in the support body 11, and an elastic claw 24 that is an engaging portion that engages with the recess 124 by pressing the cover 2 in a direction to close the wiring groove 12. When the peeling force F in the direction opposite to the pressing direction is applied to the cover 2, the engagement between the elastic claw 24 and the recess 124 is released. Therefore, the cover 2 can be easily attached to and detached from the column main body 11, and the convenience of wiring processing can be improved effectively.

  In addition, since the wiring entrances 4 and 5 are formed between the upper and lower ends 12a and 12b of the wiring groove 12 of the column main body 11 and the upper and lower ends 22a and 22b in the longitudinal direction of the cover 2, The wiring X can be accommodated throughout, and the cover 2 can be easily peeled off by placing a finger on the wiring entrances 4 and 5. Even if the furniture T with the top plate is moved while the wiring X in the wiring groove 12x is pulled out from the wiring entrance 5 and connected to the outlet D1 of the wall D, the wiring X exceeds a certain level. Since the cover 2 is peeled off when the force is applied, it is possible to prevent the wiring X from being stressed and to effectively protect it from damage or breakage. The same applies to the case where the PC is dragged while the wiring drawn out from the wiring entrance 4 is connected to the PC placed on the top board A.

  Further, since at least the wiring entrance / exit 5 on the lower end side is formed in a substantially circular shape between the lower end portion 12b of the wiring groove 12 and the lower end portion 22b in the longitudinal direction of the cover 2, the lead-out direction of the wiring X is Even if it is made with respect to various orientations, it is possible to prevent the wiring X from being stressed.

  As the engagement structure, the elastic claw 24 extends from the left and right edges 2a and 2b of the cover 2 toward the wiring groove 12, while the recess 124 is located at the left and right corresponding positions on the inner surface of the wiring groove 12, so Since the claw 24 is configured to engage with the recess 124 by elastic force in a direction away from each other and to be released from engagement with the recess 124 by elastic deformation in a direction close to each other, the left and right elastic claws 24 are arranged. A specific detaching structure between the cover 2 and the wiring groove 12 can be effectively realized while securing the wiring space Z between the two.

  Then, using the elastic claws 24 of the cover 2, a restricting portion 25 that restricts the wiring X from protruding laterally from the side edges 2 a and 2 b of the cover 2 before the cover 2 is attached to the column main body 11. Therefore, the wiring X can be attached to the wiring groove 12 in a state where the wiring X does not protrude from the cover 2 while the wiring X is hooked on the cover 2.

  Further, since the vertical rib 122 extending along the longitudinal direction of the column main body 11 is formed in the central portion of the wiring groove 12x in the groove width direction, the strength of the leg column 1 is improved and an imaginary line is shown in FIG. In this way, the wiring X can be divided between the left and right sides of the vertical rib 122. In particular, if the material of the vertical rib 122 is conductive, it can be used to avoid electromagnetic interference between the power lines and the communication lines by passing the power lines and the communication lines through the separated wiring spaces 12x.

  Further, since the lateral rib 123 intersecting with the longitudinal direction is provided at an intermittent position along the longitudinal direction of the column main body 11, a part of the lateral rib 123 is notched to form the groove bottom 123 a of the wiring groove 12. Further, the strength of the leg support 1 can be further improved without impairing the wiring function.

  In addition, the wiring groove 12 and the cover 2 are tapered downward, and the cover 2 is finely moved downward with respect to the wiring groove 12 after mounting, whereby the correspondence between the side edges 2a and 2b of the cover 2 and the column main body 11 is achieved. Since the opening edges 11a and 11b to be adhered can be brought into close contact with each other, a neat appearance can be ensured with the cover 2 attached. In addition, the edges 2a and 2b of the cover 2 are brought into close contact with the opening edges 12c and 12d of the wiring groove 12 by fitting the cover 2 to the wiring groove 12 slightly above the predetermined mounting position and sliding the cover 2 downward therefrom. As compared with the case of mounting in the close contact state from the beginning, the mounting work and the reverse peeling work are further simplified.

  In particular, the leg B of this embodiment is provided so that the caster 3 can move up and down so as to perform a damper action. Therefore, by appropriately guiding the wiring X, the upper end portion of the caster body 31 and the lower end portion 1b of the leg column 1 are provided. The possibility that the wiring X is sandwiched between them can be effectively reduced.

  And since the furniture T with a top plate is comprised by supporting the top plate A using four said legs B, the furniture T with a top plate is simple only of the top plate A and the leg B fundamentally. Even if it is a structure, a wiring function can be provided effectively.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, as shown in FIG. 3, the guide portion 121 is configured to be inclined in the above embodiment. However, as shown in FIG. 13, the guide portion 121z is configured to have a curved shape, and the tangential direction at the opening end 121a. A configuration is conceivable in which D is set so as not to intersect the space Y necessary for the swing motion of the caster 2.

  Moreover, in the said embodiment, it was set as the structure which provided the recessed part 124 which is a to-be-engaged part in the side edges 11c and 11d of the support | pillar main body 11, and also provided the elastic nail | claw 24 which is a to-be-engaged part in the side edges 2a and 2b of the cover 2. However, as shown in FIG. 14 (a), recesses 126 that are engaged portions are provided on the left and right sides of the vertical rib 122 and at intermittent positions along the longitudinal direction of the column main body 11, and the longitudinal direction of the cover rib 21 is further provided. It is good also as a structure which provided the elastic nail | claw 26 which is an engaging part in the intermittent position along.

  Further, as shown in FIG. 14 (b), elastic claws 127 which are engaged portions are provided at the intermittent positions along the longitudinal direction of the column main body 11 on both the left and right sides of the longitudinal rib 122, and the longitudinal direction of the cover rib 31 is provided. A configuration is also conceivable in which a recess 27 that is an engaging portion is provided at an intermittent position along.

  Further, when the wiring is not passed through the legs, there may be a configuration in which a wiring lid for closing the wiring entrances 4 and 5 is provided.

  In addition, the wiring groove 12 of the above embodiment starts from a position Q of the column main body 11 that is displaced upward by a predetermined distance from the caster mounting portion 11b and extends to a position P of the upper end portion 11b of the column main body 11. With the cover 2 attached to the main body 11, the wiring entrances 4 and 5 are opened between the upper end 22 a and the lower end 22 b of the cover 2 and the upper end 12 a and the lower end 12 b of the wiring groove 12, respectively. However, for example, as shown in FIG. 15, regardless of whether or not the cover 2 is attached to the column main body 11, the wiring entrance / exit 5 may always be opened at the lower end portion 12 b of the wiring groove 12. The same applies to the upper end portion of the wiring groove 12.

  Furthermore, the wiring groove 12 of the above-described embodiment starts from a position Q of the column body 11 displaced upward from the caster mounting portion 11b by a predetermined distance and extends to a position P of the upper end portion 11b of the column body 11. While the cover 2 is attached to the column main body 11, the wiring entrances 4 and 5 are opened at the upper end portion 12a and the lower end portion 12b of the wiring groove 12 in a direction having an angle with respect to the vertical direction. As shown in FIG. 16, the wiring groove 12 penetrates the upper end portion 11 b of the column main body 11, and the wiring inlet / outlet 4 opens in the vertical direction at the upper end portion 12 a of the wiring groove 12 with the cover 2 attached to the column main body 11. It can also be configured. If it does in this way, it will become possible to draw out wiring X on a top board now.

  Other configurations can be variously modified without departing from the spirit of the present invention.
