  However, in the conventional option member mounting structure as in Patent Document 2, since the retaining piece is fixed to the option member via the fixing means, the workability of mounting and removing the option member is deteriorated. Had a problem.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an attachment structure for an optional member that can be easily attached to and detached from the structure.

  In order to achieve the above object, in the optional member mounting structure according to the present invention, an opening is formed in the vertical mounting surface, and the concave groove has a wide inner space below at least the lower opening edge of the opening. An optional member mounting structure for mounting an optional member to a structure provided with a downward convex portion provided on the optional member and a downward locking claw on the base end surface on one end side of the first base portion, While providing a support base material integrally provided with a support recess having an opening on the upper surface of the first base, and a projecting piece having a projecting surface projecting in a horizontal direction from a base end surface on one end side of the second base, A retaining member having an insertion hole facing in the vertical direction at a position inside the both ends of the projecting piece in an extending direction perpendicular to the projecting direction of the projecting piece in a plan view in the second base, Under the groove In a state of being locked to the opening edge, a protruding piece of the retaining member is interposed between the upper surface of the first base and the upper opening edge of the groove, and the supporting recess of the supporting base and the insertion hole of the retaining member Are arranged coaxially, and the base end surface of the retaining member is brought close to or in contact with the mounting surface or the projecting surface of the projecting piece with respect to the bottom surface of the concave groove. It is characterized in that a downward convex part is fitted to the base.

  In the present invention, the downward locking claw of the supporting base is locked to the lower opening edge of the groove, and in this state, the protruding piece of the retaining member is between the upper surface of the first base and the upper opening edge of the groove. The support concave portion of the support base and the insertion hole of the retaining member are arranged coaxially, and the base end surface of the retaining member is the mounting surface or the projecting surface of the projecting piece is the bottom surface of the concave groove. In this state, the optional member can be attached to the structure by bringing the convex portion downward into the supporting concave portion and the insertion hole that are arranged coaxially.

  At this time, the supporting base material is positioned by the protruding piece of the retaining member interposed between the upper surface of the first base and the upper opening edge of the concave groove in the concave groove of the structure. And since the base end surface of the retaining member or the projecting surface of the projecting piece is close to or in contact with the surface on the structure side (the mounting surface or the bottom surface of the groove), Movement is restricted. Further, since the downward convex portion is fitted to the insertion hole at a position inside the both end portions of the projecting piece in the extending direction orthogonal to the projecting direction of the projecting piece in plan view in the second base portion, the retaining member is Movement in the direction is also restricted, thereby preventing the retaining member from being detached from the support base material. That is, when the support base member, the retaining member, and the downward convex portion are engaged with each other and attached to the concave groove, the support member is locked by the retaining member and the downward convex portion. Further, it is possible to prevent the supporting base material from falling off the concave groove.

  In the option member mounting structure according to the present invention, it is preferable that the upper surface of the first base portion is gradually inclined downward from the front side facing the base end surface toward the base end surface side.

  In the present invention, the downward locking claw of the supporting base material is locked to the lower opening edge of the concave groove, and during the mounting operation, particularly in a state where the retaining member is only superimposed on the supporting base material. Because the force that presses the retaining member against the structure side along the inclined surface of the first base portion works, it is possible to prevent the mounting position of the supporting base material and the retaining member from shifting, and the workability during assembly is improved. Can be improved.

  In the optional member mounting structure according to the present invention, at least the insertion hole of the retaining member is a circular hole or the sectional shape of the downward convex portion is circular, so that the optional member is attached to the retaining member. It is preferable to be able to rotate.

More preferably, they are in contact with each other.

  In the present invention, since the upward movement of the retaining member is restricted by bringing the lower surface of the enlarged diameter step portion into contact with the upper surface of the second base portion of the retaining member, the retaining member is reliably prevented from falling off. The option member can be attached more stably.

  In the optional member mounting structure according to the present invention, it is preferable that the support base is provided with an upward locking claw on the base end surface, and the upward locking claw is locked to the upper opening edge of the concave groove. .

In this case, since the upward locking claw is supported by the upper opening edge of the concave groove, a load is applied to the support concave portion side of the support base material due to the weight of the optional member in a state where the downward convex portion is fitted in the support concave portion. Even if it takes, it can prevent that the support recessed part side of a support base material inclines in front-down by the weight of the option member, and can attach an option member more stably.
Even when only the first base is mounted on the mounting surface, the upward locking claw functions as a retaining member, so that the first base does not fall off the mounting surface, and workability during mounting work is improved. Can be improved.

  According to the optional member mounting structure of the present invention, a support structure that does not drop off is realized by a simple structure that does not use screw members such as bolts for the support base, the retaining member, and the downward convex portion. Thus, the attachment and detachment to the structure can be facilitated, and the production cost can be reduced.

The retaining member 20 is attached to the structure side along the inclined surface of the base 11 (particularly in a state where the retaining member 20 is only superimposed on the support base material 10). Since the pressing force acts on the desk 3 side), it is possible to prevent the mounting positions of the support base material 10 and the retaining member 20 from being shifted, and the workability during assembly can be improved.

  Further, since the insertion hole 24 of the retaining member 20 is a circular hole and the cross-sectional shape of the pin member 5 is circular, the lighting fixture 2 itself is attached to the retaining member 20 in a state where the lighting fixture 2 is attached. It can be rotatably supported around the insertion hole 24.

Furthermore, since the upward locking claw 13 is provided on the support base material 10 and the upward locking claw 13 is locked to the upper opening edge 4a of the concave groove 4, in this case, the upward locking claw 13 is Since it is supported by the upper opening edge 4a of the groove 4, the weight of the lighting fixture 2 with the pin member 5 fitted to the bottomed tubular portion 14 is moved toward the bottomed tubular portion 14 side of the support base 10. Even if a load is applied, it is possible to prevent the bottomed cylindrical portion 14 side of the support base material 10 from being inclined forward and downward due to the weight of the lighting fixture 2, and the lighting fixture 2 can be more stably attached.
Even when only the base portion 11 of the support equipment 10 is attached to the partition wall 31 (concave groove 4), the base portion 11 falls off the partition wall 31 because the upward locking claw 13 functions as a retaining member. There is no fear, and workability at the time of attachment work can be improved.

  As described above, in the optional member mounting structure according to the present embodiment, the supporting base material 10, the retaining member 20, and the pin member 5 are not dropped by a simple structure that does not use a screw member such as a bolt. A support structure can be realized, and attachment and removal from the desk 3 are facilitated, and the manufacturing cost can be reduced.

As mentioned above, although embodiment of the attachment structure of the option member by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.

It may be. In short, it has a shape having a base end surface that can contact the mounting surface on one side, and the bottomed cylindrical portion 14 and the insertion hole 24 located on the front side of the base end surface are inside the both ends in the side direction of the base end surface. It is only necessary to be arranged at the position.

  Further, a configuration in which an enlarged diameter step portion is provided on the outer peripheral surface of the pin member 5 in the vertical direction and above the lower end, and the lower surface of the enlarged diameter step portion is in contact with the upper surface 21 a of the top wall portion 21 of the retaining member 20. It is also possible. In this case, since the upward movement of the retaining member 20 is restricted, the retaining member 20 can be reliably prevented from falling off, and an optional member such as the lighting fixture 2 can be more stably attached.

  In the present embodiment, the desk 3 is adopted as the structure to be supported by the clamp member 1 and the concave groove 4 provided in the partition wall 31 of the desk 3 is targeted. However, the present invention is not limited to this. . In short, as a structure to be applied, it is sufficient that an opening is formed in the vertical mounting surface, and a concave groove having a wide inner space is provided at least below the lower opening edge of the opening. .

Further, in the present embodiment, the base end surface 22a of the retaining member 20 is brought close to or in contact with the partition wall 31, and the projecting surface 23a of the projecting piece 23 is made to be the bottom surface 4c of the concave groove 4 (upward locking claw 13). However, it is also possible to adopt a configuration in which only one of the surfaces (the base end surface 11a or the protruding surface 23a) is brought close to or in contact with the forward facing surface 13a). .
Furthermore, the structure which does not form the slope which falls back from the front to the upper surface 11b of the base part 11 of the support base material 10 like this Embodiment, ie, a horizontal surface, may be sufficient.

It is also possible to omit the upward locking claw 13 of the support base material 10. The cross-sectional shapes of the bottomed cylindrical portion 14, the insertion hole 24, and the pin member 5 are not limited to being circular, and may be rectangular. For example, in the present embodiment, the insertion hole 24 of the retaining member 20 forms a circular hole and the cross-sectional shape of the pin member 5 is circular. However, the present invention is not limited to this, and the insertion hole 24 and the pin member 5 Only one of them may be circular. That is, when the pin member 5 has a square cross section, the inner diameter of the circular hole on the insertion hole 24 side may be a dimension that allows the pin member 5 to rotate. Further, when the cross-sectional shape of the insertion hole 24 is square, the square cross-section may be a shape larger than the circular hole of the pin member 5.
In addition, it is possible to appropriately replace the components in the above-described embodiments with known components without departing from the spirit of the present invention.
