The present invention is not limited only to the quantities of the components, the shapes of the components, the ratios of the sizes of the components, and the assumed positional relationships of the components described in .

As shown in FIGS. 1 and 2, the duct rail 2 to which the duct rail mounting member 1 is attached is made of metal such as aluminum, and is formed into a long length with the same cross section by extrusion molding. This duct rail 2 has an upper surface part 3, left and right side parts 4, and a lower surface part, a space part 6 is formed inside, and an opening part 7 is formed in the central longitudinal direction of the lower surface part to separate the left and right lower surface parts. This constitutes the left and right flanges 5. The duct rail 2 has mounting grooves 9 formed on the upper and lower insides of the left and right side portions 4 for mounting the supports 8 thereon. The mounting groove 9 is formed by protrusions 10 that protrude from the upper surface portion 3 and the left and right inner walls of the flange 5 to face each other.
Note that a convex portion for regulating the mounting direction is formed on one of the left and right side portions 4 so as to protrude downward from the flange 5 in the longitudinal direction.
The duct rail 2 is installed with its upper side fixed to an installation surface such as a ceiling surface by screws or the like. The duct rail 2 can be used by removably attaching an outlet, a lighting device, a display device, a signboard, an exhibit, etc. via a mounting member such as a hanging hook at any position along the length of the duct rail 2. can.

The pair of left and right supports 8 have upper and lower support parts 11 and mounting parts 12 that project from the support parts 11 in the vertical direction. The upper and lower support parts 11 of each of the supports 8 are inserted into the upper and lower mounting grooves 9 from one end of the duct rail 2 to the other end, and thereby held. It is arranged to protrude from between the portions 10 toward the center inside the duct rail 2. A power supply conductor holding groove 14 for holding the power supply conductor 13 is formed along the length direction of the duct rail 2 on the front end side of the upper and lower support parts 11 .

The power supply conductor 13 is constituted by a long conductive plate. The power conductor 13 is inserted into the power conductor holding groove 14 from the end of each support 8, for example, and held therein.

Note that if the mounting member 1 is not intended to be used as a device that requires power supply (e.g., an outlet, a lighting fixture, a display device, etc.), the duct rail 2 can be equipped with a power supply conductor 13 and a power supply conductor holding groove 14. Can be omitted.

The duct rail mounting member 1 shown in FIGS. 3 and 4 is made of, for example, an insulating resin, and is used by being attached to any position in the longitudinal direction of the duct rail 2, as shown in FIGS. 1 and 2.

In this duct rail mounting member 1, a planar contact surface portion 17 is formed on the upper surface of a mounting member main body 16 having a hook portion 15 below. The contact surface portion 17 is formed into a planar shape having a side longer than the length in the width direction of the opening 7 formed in the longitudinal direction of the duct rail 2 . The insertion attachment piece 18 is provided above the contact surface 17 and engages between the left and right flanges 5 of the duct rail 2 and the lower support portions 11 of the left and right supports 8 (hereinafter referred to as the insertion gap 20). be done. The insertion attachment piece 18 is formed in a thick plate shape and a substantially rectangular shape in a direction diagonal to the central axis of the contact surface portion 17 . The insertion attachment piece 18 is formed so that one side in the transverse direction has a length shorter than the opening 7 of the duct rail 2. In the lateral direction of one or both of the insertion mounting pieces 18 (if provided on both sides, they are provided on opposite sides), there is a plate-shaped plate having an elastic force (spring force) in the vertical direction and directed toward the tip side. A press-fitting fixing piece 19 is also formed which is inclined downward. As shown in FIGS. 3 and 5, the bottom surface of the tip of the press-fitting fixing piece 19 is disposed below the bottom surface of the tip of the engagement attachment piece 18. Note that a notch is formed between the insertion mounting piece 18 and the press-fitting fixing piece 19. Further, the press-fitting fixing piece 19 presses the flange 5 when it is inserted into the insertion gap 20 of the duct rail 2. At this time, the insertion attachment pieces 18 come into contact with the lower surfaces of the lower support portions 11 in the left and right supports 8 .
As shown in FIG. 5, the tip corner portion of the press-fitting fixing piece 19 adjacent to the engaging attachment piece 18 allows the press-fitting fixing piece 19 to smoothly engage the upper surface of the flange 5 of the duct rail 2 during rotation locking. It is formed on the inclined surface 19a in order to be able to do so.

The length of the engagement gap 20 in the vertical direction is equal to the thickness of the engagement attachment piece 18 and the protrusion length of the bottom surface position of the tip of the press-fitting fixing piece 19 that protrudes downward from the lower surface of the engagement attachment piece 18. The thickness of the engaging attachment piece 18 and the position of the tip of the press-fitting fixing piece 19 are set so as to be slightly shorter than the added length.

As shown in FIG. 3, a detachment prevention part 15a is attached to the hook part 15 provided at the lower part of the duct rail mounting member 1, as shown in FIG. There is. Further, the hook portion 15 is rotatably attached to the attachment member main body 16 (as required).

As shown in FIG. 4, the insertion attachment piece 18, which is formed in a substantially rectangular shape on the left and right, has an end on the side (installation side) that is inserted into the insertion gap 20 of the duct rail. It is shorter than one longitudinal side of the corner adjacent to the press-fitting fixing piece 19 and is formed in an arc shape. Further, the end of the engagement mounting piece 18 extending from the arc-shaped top to the opposite engagement side is formed into a straight line. Furthermore, the end of the press-fitting fixing piece 19 provided on the opposite side of the insertion attachment piece 18 is set to be flush with the linear portion of the insertion attachment piece 18 .
In order to attach the mounting member 1 to the duct rail 2, the insertion attachment piece 18 and the pressure contact fixing piece 19 are connected in the longitudinal direction of the opening 7 of the duct rail 2, and the attachment member body consisting of the insertion attachment piece 18 and the pressure contact fixation piece 19 is 16 through the opening 7 of the duct rail 2 so that both longitudinal sides thereof are parallel (see FIG. 6). Here, when trying to rotate the insertion mounting piece 18 and the pressure contact fixing piece 19 clockwise, the pressure contact fixation piece 19 protrudes downward from the lower surface of the entry installation piece 18, so that the flange 5 of the duct rail 2 Since they come into contact with each other, rotation is prevented. On the other hand, when it is rotated counterclockwise, the outer corner of the insertion mounting piece 18 is formed in an arc shape centered on the rotation axis, so that the duct rail is not blocked by the flange 5 of the duct rail 2. The engagement mounting piece 18 is smoothly engaged in the engagement gap 20 of No. 2. By further rotating, the inclined surface 19a formed on the tip side of the press-fitting fixing piece 19 smoothly moves to the upper surface of the flange 5 of the duct rail 2, and presses from the upper surface side of the flange 5 to transition to the connected state ( (See Figure 7).
In this way, when crossing and engaging from the opening 7 of the duct rail 2 into the engagement gap 20, the left and right engagement mounting pieces 18 are engaged by rotating the duct rail mounting member 1 counterclockwise. The side end portion can be inserted into the insertion gap 20 of the duct rail 2.

The press-fitting fixing piece 19 is provided on the anti-engagement side of the left and right engagement mounting pieces 18, and its ends are flush with the linear ends of the left and right engagement mounting pieces 18, so that the length direction is sufficiently long. This ensures elasticity. The length between the ends of the insertion mounting piece 18 and the length between the ends of the press-fitting fixing piece 19 are such that when the insertion and rotation are installed, the linear ends of the left and right insertion installation pieces 18 and The end portions of the press-fitting fixing pieces 19 are formed to have a length close to or in contact with the side surfaces of the protrusions 10 of the left and right flanges 5.
In addition, the left and right insertion mounting pieces 18 and the left and right press-fit fixing pieces 19 formed on the contact surface part 17 of the attachment part main body 16 have the outer shape of the contact surface part 17 when viewed from the top surface as shown in FIG. It is formed point-symmetrically around the center point of the circle.

When inserting the left and right engagement mounting pieces 18 and press-fitting fixing pieces 19 through the opening 7 of the duct rail 2 and crossing them into the engagement gap 20, rotate the attachment member body 16 counterclockwise from the state shown in FIG. When it is rotated 90 degrees, the state shown in FIG. 7 is reached, and the straight ends of the left and right insertion mounting pieces 18 and the press-fitting fixing pieces 19 abut against the sides of the protrusions 10 of the left and right flanges 5, and the rotation is more than 90 degrees. It is now impossible to do so. That is, the mounting portion main body 1 is prevented from rotating as it is and coming off from the duct rail 2. Therefore, in order to remove the attachment member 1, it must be rotated clockwise, which is the insertion side. That is, the attachment member main body 16 attached to the duct rail 2 is configured to be rotatable only on the removal side (insertion side) in the direction of the arrow shown in FIG. 7 (clockwise).

The distance between the lower surface of the insertion mounting piece 18 of the mounting member 1 and the flat contact surface portion 17 provided on the upper surface of the mounting member main body 16 is set to be slightly larger than the thickness of the lower surface portion 8 of the duct rail 2 and the flange 5. .

Here, the length of the engagement gap 20 in the vertical direction is equal to the thickness of the engagement attachment piece 18, and the protrusion length of the lower surface position of the tip of the press-fitting fixing piece 19 that protrudes downward from the lower surface of the engagement attachment piece 18. The thickness of the engaging attachment piece 18 and the position of the tip of the press-fitting fixing piece 19 are set so as to be slightly shorter than the length of the press-fitting fixing piece 19. Therefore, the press-fitting fixing piece 19 has elastic force in the vertical direction, and its lower surface on the distal end is lower than the lower surface of the distal end of the engaging mounting piece 18 (slanting downward toward the distal end). Since the right and left flanges 5 are pressed, the insertion mounting piece 18 inserted into the insertion gap 20 of the duct rail 2 is pressed against the lower surface of the lower support part 11 of the support body 8. However, the duct rail mounting member 1 can be positioned at a predetermined position on the duct rail 2 and fixed by pressing.

The press-fitting fixing piece 19 adjusts and sets the elastic force in the vertical direction to adjust the force for fixing the mounting member 1 to the duct rail 2 and the force for moving the mounting member 1 along the duct rail 2. It is possible to set it arbitrarily.

Furthermore, although the illustrated example shows an example in which the press-fitting fixing piece is made of insulating resin and is integrally provided with the mounting member, it is also possible to form a plate spring as a separate member as the press-fitting fixing piece, and to attach it in place. It can also be configured to be attached to a piece. Here, if the mounting member 1 is not intended for electrical equipment such as an outlet, a lighting fixture, or a display device, the plate spring as a press-fitting fixing piece, which is a separate member, should not be made of insulating resin. Good too.

In addition, the pressure welding fixing piece in the illustrated example is plate-shaped and has elastic force (spring force) in the vertical direction, and is inclined downward toward the distal end so that the lower surface of the distal end is attached to the distal end of the mounting piece. Although an example is shown in which the lower surface of the distal end side is located below the lower surface of the distal end of the insertion attachment piece, it is necessary to form the distal end side lower surface below the distal end side. It is not necessary to form it so that it slopes downward.

As described above, the duct rail mounting member according to the embodiment can be positioned and fixed at any position on the duct rail 2, and the fixed position can be changed.

As the duct rail mounting member, an outlet, a lighting device, a display device, a signboard hanging device, an exhibit hanging device, etc. are applied. When an outlet, a lighting device, or a display device is applied, power is supplied from power conductors 13 provided on the front end surfaces of the upper and lower supports 11 of the support 8 .
The present invention is not limited to the embodiments described above, and can be modified as appropriate within the scope of the claims, the entire specification, and the drawings without departing from the gist or idea of the invention.
