- Incidentally, in the case in which a wiring of an electronic device installed on a top plate of a desk with a vertically moving top plate is connected to a power supply socket installed on a floor or a wall of a working space and exposed to a space below the top plate, when the top plate is raised and lowered, the wiring of the electronic device below the top plate is deformed or moved according to the raising and lowering of the top plate.
- For this reason, when wiring of the electronic device is performed, consideration needs to be given to wiring that is deformed or moved according to the raising and lowering of the top plate not being hooked by an article such as a wagon or the like installed below the top plate. In particular, when a plurality of electronic devices are installed on the top plate, wiring of these devices takes time and labor.
- On the other hand, when a socket portion of a power source tap (OA tap) is attached to a back side of the top plate and the wiring of an electronic device installed on the top plate of the desk with a vertically moving top plate is connected to the socket portion of the power source tap, since hardly any of the wiring of the electronic device is exposed in the space below the top plate, in particular, on the floor surface, the wiring of the electronic device is not deformed or moved according to raising and lowering of the top plate. However, if the socket portion of the power source tap protrudes downward from a back surface of the top plate and the top plate approaches or comes in contact with an article such as a wagon or the like installed below the top plate when the top plate is lowered, the socket portion of the power source tap may be sandwiched between the top plate and the article and damage the power source tap or the article. In addition, when the socket portion of the power source tap protrudes downward from a back side of the top plate, a user may come in contact with the socket portion of the power source tap.
- Here, the present invention has an object of providing a desk with a vertically moving top plate capable of preventing a power source tap installed below a top plate from coming in contact with an article such as a wagon installed below the top plate or a user.
- In order to achieve the aforementioned objects, a desk with a vertically moving top plate according to a first aspect of the present invention is a desk with a vertically moving top plate having a top plate, leg parts disposed on a floor surface and configured to support the top plate to raise and lower such that it is able to be raised and lowered, and a raising and lowering mechanism configured to raise and lower the top plate, wherein a concave section opening downward and configured to accommodate a socket portion of a power source tap to which an electronic device is able to be connected is formed in the top plate.
- In addition, in the first aspect of the present invention, since the concave section configured to accommodate the socket portion of the power source tap is formed in the top plate, a wiring of the electronic device installed on the top plate can be connected to the socket portion of the power source tap. Then, as the socket portion of the power source tap is accommodated in the concave section, the socket portion of the power source tap can be prevented from protruding from a lower surface of the top plate.
- For this reason, even when the top plate approaches or comes in contact with an article such as a wagon or the like installed below the top plate when the top plate is lowered, the socket portion of the power source tap is not sandwiched between the top plate and the article, and thus, the power source tap or the article can be prevented from being damaged.
- In addition, since the socket portion of the power source tap does not protrude from the lower surface of the top plate, it is possible to prevent a user from coming in contact with the socket portion of the power source tap.
- Further, the socket portion of the power source tap represents a portion in which a socket into which a plug of an electronic device is inserted is installed, and the wiring portion of the power source tap represents a wiring configured to supply power to the socket portion.
- In addition, in the desk with a vertically moving top plate according to a second aspect of the present invention, the socket portion of the power source tap may be magnetically attached on an inner surface of the concave section.
- As the above-mentioned configuration is provided, the socket portion of the power source tap can be easily fixed into the concave section. In addition, a position of the socket portion of the power source tap can be easily changed.
- In addition, in the desk with a vertically moving top plate according to a third aspect of the present invention, the inner surface of the concave section may have a bottom surface section parallel to the floor surface on which the desk with a vertically moving top plate is disposed, and side surface sections extending downward from the bottom surface section, and the socket portion of the power source tap may be magnetically attached on at least one of the bottom surface section and the side surface sections.
- When the socket portion of the power source tap is magnetically attached on the bottom surface section and when magnetically attached on the side surface sections, an orientation of the socket portion of the power source tap is changed. For this reason, as the socket portion of the power source tap is magnetically attached on at least one of the bottom surface section and the side surface sections to match a shape of the concave section or the socket portion of the power source tap, the socket portion of the power source tap does not protrude from the concave section, and the socket portion of the power source tap can be accommodated in the concave section as a whole.
- In addition, in the desk with a vertically moving top plate according to a fourth aspect of the present invention, a hole section through which a wiring of an electronic device passes in an upward/downward direction may be formed in the top plate, and the hole section may be disposed at a position overlapping the concave section when seen in a plan view.
- As the above-mentioned configuration is provided, the wiring of the electronic device on the top plate can easily reach the concave section, and simplification of the wiring can be achieved. For this reason, the wiring of the electronic device can be easily performed while improving appearance of the wiring of the electronic device.
- In addition, in the desk with a vertically moving top plate according to a fifth aspect of the present invention, the concave section may extend such that at least one end portion in an extension direction reaches an edge portion of the top plate, and a wiring portion of the power source tap may be extracted to the outside of the top plate from the edge portion of the top plate through the concave section.
- As the above-mentioned configuration is provided, since the wiring portion of the power source tap does not hang down from the top plate, the wiring portion of the power source tap can be prevented from being hooked by an article such as a wagon or the like installed below the top plate when the top plate is raised and lowered. In addition, since the wiring portion of the power source tap does not hang down from the top plate, it is possible to prevent a user from coming in contact with the wiring portion of the power source tap.
- According to the desk with a vertically moving top plate of the present invention, it is possible to prevent the power source tap installed below the top plate from coming in contact with an article such as a wagon or the like installed below the top plate or a user.

- In the desk 1 with a vertically moving top plate according to the embodiment, since the
concave section 469 that can accommodate thesocket portion 11 a of thepower source tap 11 is formed in the top plate 4, the wiring of the electronic device installed on the top plate 4 can be connected to thesocket portion 11 a of thepower source tap 11. - Then, as the
socket portion 11 a of thepower source tap 11 is accommodated in theconcave section 469 formed in the top plate 4, thesocket portion 11 a of thepower source tap 11 can be prevented from protruding from the lower surface of the top plate 4. - For this reason, even if the top plate 4 approaches or comes in contact with an article such as a wagon or the like installed below the top plate 4 when the top plate 4 is lowered, the
socket portion 11 a of the power source tap and the article can be prevented from being damaged without thesocket portion 11 a of thepower source tap 11 being sandwiched between the top plate 4 and the article. - In addition, since the
socket portion 11 a of thepower source tap 11 does not protrude from the lower surface of the top plate 4, it is possible to prevent a user from coming in contact with thesocket portion 11 a of thepower source tap 11. - In addition, as the
socket portion 11 a of thepower source tap 11 is magnetically attached on the inner surface of theconcave section 469, thesocket portion 11 a of thepower source tap 11 can be easily fixed into theconcave section 469. In addition, a position of thesocket portion 11 a of thepower source tap 11 can be easily changed. - Further, in the embodiment, the
socket portion 11 a of thepower source tap 11 is configured to be magnetically attached on the secondhorizontal plate section 464, the secondvertical plate section 463 and the thirdvertical plate section 465 that constitute theconcave section 469. Then, an orientation of thesocket portion 11 a of thepower source tap 11 differs when magnetically attached on the secondhorizontal plate section 464, when magnetically attached on the secondvertical plate section 463 and when magnetically attached on the thirdvertical plate section 465. For this reason, as thesocket portion 11 a of thepower source tap 11 is magnetically attached on any one of the secondhorizontal plate section 464, the secondvertical plate section 463 and the thirdvertical plate section 465 to mach a shape of theconcave section 469 or thesocket portion 11 a of thepower source tap 11, thesocket portion 11 a of thepower source tap 11 can be accommodated in theconcave section 469 without protruding from theconcave section 469. - In addition, as the
wiring insertion hole 49 through which the wiring of the electronic device can be inserted in the upward/downward direction is formed in the top plate 4 and thewiring insertion hole 49 is disposed at a position overlapping theconcave section 469 when seen in a plan view, the wiring of the electronic device on the top plate 4 can easily reach theconcave section 469 and simplification of the wiring can be achieved. For this reason, the appearance of the wiring of the electronic device can be improved and wiring of the electronic device can be easily performed. - In addition, since the
concave section 469 extends in the leftward/rightward direction and both end portions in the leftward/rightward direction reach an edge portion of the top plate 4 in the leftward/rightward direction, thewiring portion 11 b of thepower source tap 11 can be extracted to the outside of the top plate 4 in the leftward/rightward direction through theconcave section 469. For this reason, since thewiring portion 11 b of thepower source tap 11 does not hang down from the top plate 4, when the top plate 4 is raised and lowered, thewiring portion 11 b of thepower source tap 11 can be prevented from being hooked by an article such as a wagon or the like installed below the top plate 4. In addition, since thewiring portion 11 b of thepower source tap 11 does not hang down from the top plate 4, it is possible to prevent a user from coming in contact with thewiring portion 11 b of thepower source tap 11. - According to the desk 1 with a vertically moving top plate as configured above, as the upper slant surface F2 inclined forward and downward is provided at an upper side of the
front end portion 4 a of the top plate 4, it is possible to prevent thefront end portion 4 a of the top plate 4 from biting into a user's body, arm, or the like. - Accordingly, the desk 1 with a vertically moving top plate can be used in a pleasant use environment. Even when a user performs standing work for a long time and the user leans forward close to the
front end portion 4 a of the top plate 4, it is possible to prevent thefront end portion 4 a of the top plate 4 from biting and a large force from being applied to a body region of a user. - In addition, the top plate 4 has the front end lower curved surface F4 formed below the
front end portion 4 a and inclined downward and rearward. As the above-mentioned configuration is provided, in comparison with the configuration in which the front end lower curved surface F4 is not formed below thefront end portion 4 a of the top plate 4, a field of view to a lower space of the top plate 4 widens. In addition, thefront end portion 4 a of the support body can be shown to be thin, and an appearance of the top plate 4 can be improved. - Further, the
operation units 7 configured to operate an elevating operation of the raising and loweringmechanism unit 5 are installed at a lower side of thefront end portion 4 a and a rear side of the front end lower curved surface F4 of the top plate 4. As the above-mentioned configuration is provided, visibility of theoperation unit 7 installed below thefront end portion 4 a of the top plate 4 is increased by the front end lower curved surface F4. - Accordingly, operability when a user vertically elevates the top plate 4 can be improved.
- In addition, in the top plate 4, as the
top surface 4 t, the upper slant surface F2, the front end upper curved surface F3 and the front end lower curved surface F4 are formed to be integrally continuous with each other, anouter surface 211 f of the top plate 4 becomes smooth. - Further, when a shape of the
front end portion 4 a of the top plate 4 is formed of a wooden material, a large thickness of thefront end portion 4 a in the upward/downward direction needs to be provided to secure the strength for thefront end portion 4 a, for example. On the other hand, when the top plate 4 is constituted by a base member 21 formed of steel, and thesurface coating material 12, the strength for the top plate 4 can be secured while reducing a thickness of thefront end portion 4 a of the top plate 4 such it becomes thin. - In addition, in the desk 1 with a vertically moving top plate including the above-mentioned top plate 4, the
leg bodies 2 have the raising and loweringmechanism units 5 provided at the intermediate section of the top plate 4. In this way, in the case in which the raising and loweringmechanism units 5 that constitute columns of theleg bodies 2 are disposed at the intermediate section of the top plate 4 in the forward/rearward direction, when a load is applied to thefront end portion 4 a of the top plate 4, a large moment is applied to the raising and loweringmechanism unit 5. In particular, in the desk 1 with a vertically moving top plate in which the top plate 4 can be raised and lowered, when the top plate 4 is raised and lowered, if a load is applied to thefront end portion 4 a of the top plate 4, anti-overturning properties deteriorate. - On the other hand, since the upper slant surface F2 is formed on the
front end portion 4 a of the top plate 4, when a user's hand or an article is placed on the top plate 4, the user's hand or the article cannot be easily placed on the upper slant surface F2. Accordingly, a region where the load is applied is a region behind the upper slant surface F2 due to disposition of the hand or the article placed on the top plate 4. Accordingly, an action point of the load is disposed closer to the raising and loweringmechanism unit 5, and a moment applied to the raising and loweringmechanism unit 5 is reduced. Accordingly, anti-overturning properties of the desk 1 with a vertically moving top plate can be improved. - In addition, in the top plate 4, the upper slant surface F2 is formed on the
front end portion 4 a only, and therear end portion 4 b and theside end portions 4 c are formed by the hanging-down surface Fv. Accordingly, when therear end portion 4 b or theside end portions 4 c of the desk 1 with a vertically moving top plate is disposed to abut against the wall surface, other household goods, or the like, a gap or a concave section cannot be easily generated between therear end portion 4 b or theside end portions 4 c of the top plate 4 and the wall surface or the other household goods. As a result, the article can be prevented from falling off from the top plate 4. - Hereinabove, while the embodiment of the desk 1 with a vertically moving top plate according to the present invention has been described, the present invention is not limited to the embodiment and may be appropriately modified without departing from the spirit of the present invention.
- For example, while the desk 1 with a vertically moving top plate is configured to have the pair of raising and lowering
mechanism units operation unit 7 in the embodiment, the mechanism configured to raise and lower the top plate 4 may be, for example, a mechanism using a gas spring, a gear, or the like, in addition thereto. - In addition, while the embodiment has a configuration in which the top plate 4 has the core 41 formed by processing a metal plate such as a steel plate or the like, and the
surface material 42 such as a melamine board or the like configured to cover the surface of the core 41, the top plate 4 may be constituted by a plywood formed of wood as long as the concave section configured to accommodate thesocket portion 11 a of thepower source tap 11 is formed. - In addition, while the
concave section 469 extends in the leftward/rightward direction and is formed at a rear side of the top plate 4 in the embodiment, a shape or a place formed with respect to the top plate 4 may be appropriately set. - In addition, while the inner surface of the
concave section 469 has a magnetic property in the embodiment, the magnetic property may not be provided. In this case, thesocket portion 11 a of thepower source tap 11 may be fixed to theconcave section 469 by a fixing tool such as a screw, a hook formed in theconcave section 469, or the like. In addition, a plate member on which thesocket portion 11 a of thepower source tap 11 can be placed may be installed below theconcave section 469. - In addition, in the embodiment, the second
horizontal plate section 464, the secondvertical plate section 463 and the thirdvertical plate section 465 that constitute theconcave section 469 have a magnetic property, thesocket portion 11 a of thepower source tap 11 is magnetically attached on the sections, and a portion of the inner surface of theconcave section 469 has a magnetic property. The socket portion of thepower source tap 11 may be magnetically attached on the portion having a magnetic property. - In addition, while the
wiring insertion hole 49 is formed in the top plate 4 in the embodiment, thewiring insertion hole 49 may be not formed. - In addition, while the two wiring insertion holes 49 are formed at positions overlapping the
concave section 469 when seen in a plan view in the embodiment, the wiring insertion holes 49 may be formed at positions that do not overlap theconcave section 469 when seen in a plan view and the number of wiring insertion holes 49 formed in the top plate 4 may be appropriately set. - In addition, while the
concave section 469 extends in the leftward/rightward direction, both end portions in the leftward/rightward direction reach the edge portion of the top plate 4 in the leftward/rightward direction and thewiring portion 11 b of thepower source tap 11 is extracted to the outside of the top plate 4 in the leftward/rightward direction through theconcave section 469 in the embodiment, thewiring portion 11 b of thepower source tap 11 may be extracted to the lower side or the outer side of the top plate 4 without passing through theconcave section 469. - In addition, for example, while the upper slant surface F2 is formed as the upper inclined section of the
front end portion 4 a of the top plate 4 in the embodiment, the upper inclined section is not limited to a planar inclined surface and may be a curved surface as long as the upper inclined surface may be inclined forward and downward. Similarly, the lower inclined surface formed on thefront end portion 4 a is also not limited to the front end lower curved surface F4 and a planar inclined surface may be formed as long as the lower inclined surface is inclined downward and rearward. - In addition, while the upper slant surface F2 is formed on only the
front end portion 4 a of the top plate 4 in the embodiment, there is no limitation thereto. According to a use type of the desk 1 with a vertically moving top plate, a configuration in which the upper slant surface F2, the front end lower curved surface F4, and so on, are formed on therear end portion 4 b or theside end portions 4 c of the top plate 4 in the same manner may be provided. - In addition, the desk 1 with a vertically moving top plate may have any other configuration such as any configuration, disposition, number of installed
leg bodies 2, and so on, as long as the top plate 4 can be raised and lowered. - In addition, the configuration of the raising and lowering
mechanism unit 5 may be any other configuration as long as the top plate 4 can be raised and lowered. - According to the desk with a vertically moving top plate of the present invention, the power source tap installed below the top plate can be prevented from coming in contact with an article such as a wagon or the like installed below the top plate or a user.
