Description

  The present invention relates to furniture that is configured such that an option member can be attached to a furniture body via an option attachment device.

  Conventionally, an optional member can be mounted so as to be movable along the longitudinal direction by inserting an insertion part of an optional member such as a lighting device into a feeding rail that extends in the longitudinal direction and has a feeding electrode inside. Is known (see, for example, Patent Document 1). A power receiving electrode is provided in the insertion portion in advance, and when the optional member is attached, the power receiving electrode is electrically connected to the power feeding electrode.

  In the above structure, the power supply rail not only supplies power to the option member, but also plays a role of mechanically supporting the option member. In such a case, for example, when the weight of the optional member is large, or when the optional member is attached from the side to the feeding rail that is open to the side, an excessive load is applied to the insertion portion of the feeding rail or the optional member. There is a risk of deformation.

JP 2008-305737 A

  An object of the present invention is to avoid problems caused by mechanically supporting an optional member on the power supply rail itself.

  That is, the furniture according to the present invention is a furniture in which an option member can be attached to the furniture body via an option attachment device, and the option member receives the power to be supplied to the option body and the option body. And the optional attachment device has a power feeding electrode that has an opening into which the insertion part is inserted and that contacts the power receiving electrode inside the opening. The power supply rail is provided along the longitudinal direction of the power supply rail and mechanically supports the optional body regardless of whether the power receiving electrode is in contact with the power supply electrode or not. And a support rail that can arbitrarily change the support position of the option main body along the longitudinal direction.

  In the present invention, the option member is attached mainly such that the option main body is supported by the support rail. Thereby, the load applied to the insertion portion of the power supply rail or the optional member can be reduced as compared with the conventional mode in which the power supply rail itself supports the optional member.

  In particular, in a state where the option main body is supported by the support rail, the insertion portion electrically connects the power receiving electrode to the power feeding electrode, and the power receiving electrode from the power feeding electrode. If it can be displaced between the electrical shut-off position, the optional part can be attached to the option mounting device when the optional part is not used temporarily by setting the insertion part to the shut-off position. It is possible to cut off the energization to the option member while remaining.

  Moreover, if it has a lock mechanism which locks the said option main body with respect to the said support rail so that it cannot be removed, an option member will not fall inadvertently from an option attachment apparatus during use of an option member.

  As an example of such a locking mechanism, there is one that locks the option main body with respect to the support rail so as not to be removed by using the operation of the insertion portion.

  As a configuration for realizing such a locking mechanism, the optional main body engages with a predetermined portion of the support rail to prevent the drop from the support rail, while being separated from the predetermined portion of the support rail with elastic deformation. A locking portion that allows the option main body to be removed from the support rail when the insertion portion is in the connection position, and the elastic deformation of the locking portion is prevented when the insertion portion is in the connection position. The thing which becomes non-removable with respect to a support rail is mentioned.

  Further, as another example of the lock mechanism, a lock member that is separate from the option main body, and a fixing member for detachably attaching the lock member to a position where the option main body can be prevented from being detached from the support rail. The thing which comprises a tool is mentioned.

  If the furniture body is a furniture with a top plate having a top plate, and the option mounting device is installed on the counter-use end side of the top plate, various option members on the counter-use end side of the furniture with the top plate Can be attached.

  In particular, as long as the optional mounting device is attached to the counter-use end side of the top plate via a clamp, any furniture with a top plate with a top plate is optional via a clamp on the top plate. By attaching the attachment device, the option member can be attached via this option attachment device.

  According to the present invention, since the option member is mechanically supported mainly by the support rail, it is possible to avoid problems caused by supporting the option member by the power supply rail itself.
