[0017] The pointed top part 111 is formed in a plate shape. For example, in a plan view, the pointed top part 111 is formed in an octagonal plate shape, but the shape of the pointed top part 111 is not limited to an octagon. The pointed top part 111 may be formed in other shapes such as a circular shape or a polygonal shape other than an octagon.

[0018] The dome apex 111 has a dome apex opening 113 formed in the center. The dome apex opening 113 is a through hole formed in the dome apex 111. Electrical wires connected to an external power source or wiring connected to an external device are inserted through the dome apex opening 113. The dome apex 111 is also provided with holes through which fasteners such as screws used for attachment to building materials are inserted (not shown in the figure).

[0019] The top plate mounting portion 112 is provided so as to protrude downward from the outer edge of the apex portion 111. The top plate mounting portion 112 is a roughly rectangular plate piece. A top plate screw hole 112a is formed in the top plate mounting portion 112. The top plate screw hole 112a is a hole that penetrates the top plate mounting portion 112 in the thickness direction of the plate. As shown in Figure 3, a top plate screw 112b is attached to the top plate screw hole 112a. The top plate screw 112b is used to fix the top plate 11 and the column portion 12. The top plate 11 is attached to the column portion 12 using the top plate screw 112b.

[0020] (Column 12) Figure 5 is a perspective view of the column portion 12 of the direct mounting device 1 according to an embodiment. The column portion 12 will be described using Figure 5. As shown in Figure 5, the column portion 12 is formed in a plate shape and has a rectangular slit 124 that penetrates in the thickness direction of the plate. As shown in Figure 1, in the direct mounting device 1, the column portion 12 is provided so as to protrude from the top plate 11 to one side relative to the plate surface of the top plate 11.

[0021] The column portion 12 is a member that extends in the vertical direction (Z-axis direction). The column portion 12 is provided between the top plate 11 and the bottom portion 13, and is provided so as to extend between the top plate 11 and the bottom portion 13.

[0022] The column portion 12 is attached to the top plate 11 at one end and to the spring support bracket 14 at the other end. In other words, the upper part of the column portion 12 is attached to the top plate 11 and the lower part is attached to the spring support bracket 14. Furthermore, the other end of the column portion 12 is attached to the bottom 13 via the spring support bracket 14.

[0023] The surface-mount fixture 10 has at least two column portions 12. The surface-mount device 1 is arranged such that, when the equipment to be mounted 20 is attached to the surface-mount fixture 10, a pair of column portions 12 face each other via the equipment to be mounted 20. As shown in Figure 1, the surface-mount device 1 has a space formed between the pair of column portions 12. The equipment to be mounted 20 is positioned in the space between the pair of column portions 12. The column portions 12 are arranged so as to be located to the side of the equipment to be mounted 20 when the equipment to be mounted 20 is attached to the surface-mount fixture 10.

[0024] The pair of column sections 12 constitute a part of the outer casing of the direct mounting device 1. When the equipment to be mounted 20 is attached to the direct mounting fixture 10, the equipment to be mounted 20 is positioned inside the pair of column sections 12. In the radial direction, the pair of column sections 12 cover a part of the outside of the equipment to be mounted 20. Each column section 12 has a main column section 121 and a side column section 122.

[0025] The main column portion 121 is formed in the shape of a rectangular plate. However, the shape of the main column portion 121 is not limited to a rectangle; for example, it may be formed in other polygonal shapes besides a rectangle.

[0026] The main column portion 121 has a positioning groove 123 formed at its lower end, which extends long in the vertical direction (Z-axis direction). The positioning groove 123 is a hole that penetrates the main column portion 121 in the plate thickness direction. The positioning groove 123 is formed in a notch shape with its lower end opening downwards. As shown in Figure 1, the positioning portion 145 of the spring receiving bracket 14, which will be described later, is inserted into the positioning groove 123.

[0027] The main column section 121 has a main screw hole 121a formed at its lower end. The main screw hole 121a is a hole that penetrates the main column section 121 in the thickness direction. As shown in Figure 3, a main screw 121b is attached to the main screw hole 121a. The main screw 121b is used to fix the main column section 121 to the spring receiving bracket 14. The main column section 121 is attached to the spring receiving bracket 14 using the main screw 121b. In addition, the main column section 121 is attached to the bottom section 13 via the spring receiving bracket 14 by attaching the main screw 121b to the main screw hole 121a.

[0028] A rectangular slit 124 is formed in the main column portion 121, penetrating in the thickness direction. The slit 124 is formed, for example, near the center of the main column portion 121 in the vertical direction (Z-axis direction). However, the slit 124 is not limited to being formed near the center; it may be formed in the vertical direction (Z-axis direction) between the main screw hole 121a and the positioning groove 123 and the upper end of the main column portion 121.

[0029] The column side portion 122 is provided so as to protrude from the end of the column main portion 121 on the depth side (X-axis direction) toward the width side (Y-axis direction). The column side portion 122 is provided so as to protrude at an obtuse angle with the column main portion 121. The column side portion 122 is provided so as to extend vertically (Z-axis direction) along the side edge of the column main portion 121.

[0030] In one column section 12, two column section sides 122 are provided, and a pair of column section sides 122 are provided on both sides of the column section main section 121 via the column section main section 121. The pair of column section sides 122 are formed by bending sheet metal toward the side where the equipment to be attached 20 is to be placed.

[0031] The side portion 122 of the column has a side screw hole 122a formed at its upper end. The side screw hole 122a is a hole that penetrates the side portion 122 of the column in the direction of the plate thickness. As shown in Figure 3, a top plate screw 112b is attached to the side screw hole 122a. The side portion 122 of the column is attached to the top plate mounting portion 112 by the top plate screw 112b attached to the side screw hole 122a. The column 12 is attached to the top plate 11 by the top plate screw 112b being attached to the side screw hole 122a and the top plate screw hole 112a.

[0032] (bottom 13) Figure 6 is a perspective view of the bottom portion 13 and spring support fitting 14 of the direct mounting device 1 according to an embodiment. The bottom portion 13 and spring support fitting 14 will be explained using Figure 6. The bottom portion 13 constitutes a part of the outer shell of the direct mounting device 1.

[0033] The bottom portion 13 is formed in a disc shape. The mounting equipment 20 is inserted through the bottom portion 13. A spring retaining bracket 14 is attached to the bottom portion 13. A bottom opening 131 is formed in the central part of the bottom portion 13, penetrating in the vertical direction (Z-axis direction). Because the bottom opening 131 is formed, the bottom portion 13 is formed in an annular shape when viewed in the vertical direction (Z-axis direction). The mounting equipment 20 is inserted through the bottom opening 131.

[0034] The bottom opening 131 is formed in a circular shape, and a pair of notches 132 are provided at opposing positions on the periphery of the bottom opening 131 in the width direction (Y-axis direction). The notches 132 are portions of the inner periphery of the bottom opening 131 of the bottom 13 that are cut out.

[0035] (Spring support bracket 14) The direct-mount fixture 10 has a pair of spring receiving brackets 14. The pair of spring receiving brackets 14 are arranged to face each other with the bottom opening 131 in between when viewed in plan. The pair of spring receiving brackets 14 have spring receiving portions 142 that face each other with the bottom opening 131 in between when viewed in plan, and connect the pair of column portions 12 and the bottom portion 13. The spring receiving brackets 14 are the parts that connect the bottom portion 13 and the column portions 12, and are the parts that engage with the mounting spring 22, which will be described later.

[0036] The spring support bracket 14 is attached to the upper surface of the bottom portion 13. The upper surface of the bottom portion 13 to which the spring support bracket 14 is attached is the surface on which the top plate 11 is placed, and is the surface facing the top plate 11. The spring support bracket 14 is positioned along the notch 132. The spring support bracket 14 is also attached to the inner surface of the column portion 12. The inner surface of the column portion 12 to which the spring support bracket 14 is attached is the surface on which the pair of column portions 12 face each other, and is the inner surface of the main column portion 121.

[0037] The spring support fitting 14 has a main spring support fitting portion 141, a spring support portion 142, and a spring support connecting portion 143. The spring support fitting 14 is formed by bending a single sheet of metal. However, the spring support fitting 14 is not limited to being formed by bending a single sheet of metal; for example, it may be formed by connecting multiple sheets of metal.

[0038] The main part 141 of the spring support bracket is formed in a plate shape. The main part 141 of the spring support bracket is the part of the spring support bracket 14 that abuts against the bottom part 13 and is attached to the bottom part 13. As shown in Figure 6, in the width direction (Y-axis direction), one end of the main part 141 of the spring support bracket is positioned along one side of the notch 132 of the bottom opening 131 and is attached to the upper surface of the bottom part 13. The main part 141 of the spring support bracket and the bottom part 13 may be attached with fasteners such as screws, or they may be integrally formed by methods such as welding.

[0039] The spring receiving portion 142 is provided so as to protrude upward from the end of the main spring receiving bracket 141 on the bottom opening 131 side in the width direction (Y-axis direction). The spring receiving portion 142 is positioned on the surface of the bottom 13 facing the top plate 11, with the bottom opening 131 in between. The spring receiving portion 142 is provided so as to rise up toward the top plate 11 from the edge portion of the main spring receiving bracket 141 on the bottom opening 131 side. The main spring receiving bracket 141 and the spring receiving portion 142 are formed by bending sheet metal. The spring receiving portions 142 of the pair of spring receiving brackets 14 are positioned so as to face each other via the bottom opening 131 when viewed in the vertical direction (Z-axis direction).

[0040] The spring receiving portion 142 is provided with a spring stopper 144 at its upper end. More specifically, the spring receiving portion 142 is provided with a pair of spring stoppers 144 at its end facing the top plate 11, projecting toward the top plate 11. The spring stoppers 144 are formed at the end opposite to the side where the main part of the spring receiving fitting 141 is formed, in the vertical direction (Z-axis direction). The spring stoppers 144 are provided in pairs at the upper end of the spring receiving portion 142, projecting upward from both ends in the depth direction (X-axis direction).

[0041] The spring stopper 144 forms a recessed portion 144a in the upper part of the spring receiving portion 142, into which the mounting spring 22 is housed. The recessed portion 144a is a notched portion provided between the pair of spring stoppers 144 in the spring receiving portion 142. The pair of spring stoppers 144 function as stoppers that prevent the mounting spring 22, which is positioned in the recessed portion 144a formed by the spring stoppers 144, from moving in the circumferential direction. The length L is the distance between the pair of spring stoppers 144 in the depth direction (X-axis direction). The relationship between length L and the mounting spring 22 will be described later.

[0042] The spring support connector 143 is provided so as to protrude upward from the end of the main spring support fitting 141 opposite to the spring support portion 142. The spring support connector 143 is provided so as to rise from the edge of the main spring support fitting 141 opposite to the bottom opening 131 towards the top plate 11. The main spring support fitting 141 and the spring support connector 143 are formed by bending sheet metal.

[0043] A connection screw hole 143a is formed in the spring support connection portion 143. The connection screw hole 143a is a hole that penetrates the spring support connection portion 143 in the plate thickness direction. A main screw 121b is attached to the connection screw hole 143a (see Figure 3). The spring support fitting 14 is attached to the main column portion 121 by attaching the main screw 121b to the main screw hole 121a of the main column portion 121 and to the connection screw hole 143a of the spring support connection portion 143.

[0044] The spring support connection portion 143 has a positioning portion 145 that is provided so as to protrude outward in the width direction (Y direction) from its end in the depth direction (X direction). The positioning portion 145 is a plate-shaped member that protrudes from the side edge of the spring support connection portion 143 on the opposite side from the spring support portion 142. The positioning portion 145 is formed to extend in the width direction (Y direction) and also in the vertical direction (Z direction). When the column portion 12 is attached to the spring support fitting 14, the positioning portion 145 is housed in the positioning groove 123 of the column portion main portion 121. The positioning portion 145 is housed in the positioning groove 123 and engages with the forming portion of the positioning groove 123.

[0045] (Equipment to be attached 20) Figure 7 is a perspective view from above of the mounting device 1 of the embodiment, showing the mounting equipment 20. The mounting equipment 20 will be described using Figure 7. The mounting equipment 20 is a device that is attached to the direct mounting fixture 10. In the case where the direct mounting fixture 10 is not used, the mounting equipment 20 can be embedded in an opening provided in the ceiling or the like and attached to the ceiling or the like.

[0046] The equipment to be mounted 20 is a sensor device equipped with a sensor or a lighting fixture equipped with a light source such as an LED (Light Emitting Diode). Here, the sensor refers to a sensor that works in conjunction with the lighting fixture, such as an infrared sensor, an illuminance sensor, an image sensor, or a motion sensor. The equipment to be mounted 20 has a main body 21 and a pair of mounting springs 22 attached to the main body 21.

[0047] (Main body 21) The main body 21 has an edge portion 211 and a spring fixing portion 212. The main body 21 has a sensor or light source (not shown). The main body 21 is formed in a columnar shape extending in the vertical direction (Z-axis direction) and forms a housing equipped with the sensor or light source.

[0048] The edge portion 211 is provided at the lower end of the main body 21. The edge portion 211 is formed in a disc shape. The outer diameter of the edge portion 211 is larger than the opening diameter of the bottom opening 131 of the bottom portion 13. The edge portion 211 catches on the bottom portion 13 when the main body 21 is inserted through the bottom opening 131 of the bottom portion 13. When the main body 21 is inserted through the bottom opening 131 of the bottom portion 13, the edge portion 211 abuts against the lower surface 13a (see Figure 2) of the bottom portion 13 on the side opposite to the mounting surface of the spring retaining bracket 14.

[0049] The edge portion 211 covers the gap between the main body 21 and the bottom opening 131 from the opposite side of the mounting surface of the spring retaining bracket 14 when the main body 21 is inserted through the bottom opening 131 of the bottom portion 13. Because the edge portion 211 is provided to cover the gap between the main body 21 and the bottom opening 131, the gap between the main body 21 and the bottom opening 131 is not visible from the design side of the direct mounting device 1. In other words, because the edge portion 211 is provided to cover the gap between the main body 21 and the bottom opening 131, the gap between the main body 21 and the bottom opening 131 is not visible from the lower side of the direct mounting device 1.

[0050] The main body 21 has a pair of spring fixing parts 212. The pair of spring fixing parts 212 are provided on both sides of the main body 21 in the width direction (Y-axis direction). The spring fixing parts 212 are provided on the outside of the main body 21 and are provided on the outer peripheral wall of the main body 21. The spring fixing parts 212 are the parts that fix the mounting spring 22 to the main body 21.

[0051] The spring fixing portion 212 is formed in a frame shape that extends in the vertical direction (Z-axis direction). The spring fixing portion 212 has a groove 212a formed to extend in the vertical direction (Z-axis direction). The plate-shaped portion of the first spring portion 221, which will be described later, fits into the groove 212a, and the mounting spring 22 is fixed to the spring fixing portion 212.

[0052] The spring fixing portion 212 includes a locking portion 212b that protrudes outward from the outer surface of the main body 21. When the mounting spring 22 is fitted into the groove 212a, the locking portion 212b abuts against the end of the mounting spring 22 to prevent the mounting spring 22 from coming out of the spring fixing portion 212, and prevents the mounting spring 22 from moving in a direction that would cause it to detach from the spring fixing portion 212.

[0053] (Mounting spring 22) Figure 8 is a front view of the mounting spring 22 of the direct mounting device 1 according to the embodiment. Figure 9 is a side view of the mounting spring 22 of the direct mounting device 1 according to the embodiment. The mounting spring 22 will be described using Figures 1, 8 and 9.

[0054] The mounting spring 22 is a plate-shaped elastic member. The mounting spring 22 is used to attach the equipment to be mounted 20 to the surface mounting fixture 10. More specifically, the mounting spring 22 is used to suspend the equipment to be mounted 20 from the surface mounting fixture 10. The mounting spring 22 is used to connect the main body 21 to the main column portion 121 of the column portion 12. In the case where the surface mounting fixture 10 is not used, the mounting spring 22 engages with building materials such as the ceiling and is used to mount the equipment to be mounted 20 in an embedded state in an opening provided in the ceiling or the like.

[0055] The mounting springs 22 are attached to the spring fixing portion 212 of the main body 21. Each of the pair of mounting springs 22 is attached to the main body 21 and has a first spring portion 221 that extends from the top plate 11 side to the bottom portion 13 side, and a second spring portion 222 that is formed by folding back from the tip of the first spring portion 221 and abuts against the spring receiving portion 142. The bending portion 224 of the mounting spring 22 is pressed when the spring receiving portion 142 and the second spring portion 222 abut against each other. In addition, each of the pair of mounting springs 22 has a third spring portion that is formed by folding back from the tip of the second spring portion 222 and is inserted into the slit 124 of the column portion 12.

[0056] In other words, each of the pair of mounting springs 22 has a first spring portion 221 that is attached to the spring fixing portion 212 of the main body 21, and a second spring portion 222 that is formed by folding back the end of the first spring portion 221 opposite to the main body 21 and is pressed against the spring receiving portion 142. Furthermore, each of the pair of mounting springs 22 has a third spring portion 223 that is formed by folding back the end of the second spring portion 222 opposite to the first spring portion 221 and is inserted into the slit 124 of the column portion 12.

[0057] The first spring portion 221 is provided to extend in the vertical direction (Z-axis direction) and is the portion attached to the spring fixing portion 212 of the main body 21. The end of the first spring portion 221 is formed to be wide so that it fits into the groove 212a of the spring fixing portion 212. The first spring portion 221 and the second spring portion 222 are bent at their respective lower ends. The bent portion between the first spring portion 221 and the second spring portion 222 is called the bent portion 224. The mounting spring 22 has one end (upper end) of the first spring portion 221 attached to the main body 21, and the other end (lower end) that is not attached to the main body 21 is bent back to form the second spring portion 222.

[0058] The second spring portion 222 is formed by folding back from the lower end of the first spring portion 221 toward the upper end and extending in the vertical direction (Z-axis direction). The length of the second spring portion 222 in the vertical direction (Z-axis direction) is longer than the length of the first spring portion 221 in the vertical direction (Z-axis direction). The second spring portion 222 is formed to extend in the width direction (Y-axis direction) from the lower end of the first spring portion 221, and the space between the first spring portion 221 and the second spring portion 222 increases as you move from the lower end of the first spring portion 221 toward the upper end. The first spring portion 221 and the second spring portion 222 are formed in a V-shape when viewed from the front.

[0059] The length of the second spring portion 222 in the depth direction (X-axis direction) increases from the first spring portion 221 side to the third spring portion 223 side. The length of the second spring portion 222 in the depth direction (X-axis direction) on the first spring portion 221 side is smaller than the length L between the spring stoppers 144. The length of the second spring portion 222 in the depth direction (X-axis direction) on the third spring portion 223 side is larger than the length L between the spring stoppers 144.

[0060] The second spring portion 222 is formed such that the lower part of the second spring portion 222 is relatively narrower than the upper part, and the width of the second spring portion 222 increases towards the upper part of the second spring portion 222. The width W1 of the upper part 222a of the second spring is greater than the width W2 of the lower part 222b of the second spring. The upper part 222a of the second spring is the upper part of the second spring portion 222 and is the part of the second spring portion 222 that is on the side of the third spring portion 223. The lower part 222b of the second spring is the lower part of the second spring portion 222 and is the part of the second spring portion 222 that is on the side of the first spring portion 221.

[0061] Each of the pair of mounting springs 22 is formed such that the width of the second spring portion 222 becomes longer than the length L between the pair of spring stoppers 144 as it moves from the folding point 224a side with the first spring portion 221 toward the third spring portion 223 side. In other words, the mounting spring 22 is formed such that the length of the second spring portion 222 in the depth direction (X-axis direction) becomes longer than the length L between the pair of spring stoppers 144 as it moves from the folding point 224a side with the first spring portion 221 toward the third spring portion 223 side.

[0062] The second spring portion 222 is positioned between the pair of spring stoppers 144 when the equipment to be mounted 20 is attached to the direct mounting fixture 10. That is, a portion of the second spring portion 222 is positioned in the concave portion 144a when the equipment to be mounted 20 is attached to the direct mounting fixture 10. In addition, the second spring portion 222 abuts against the spring receiving portion 142 in the width direction (Y-axis direction) when the equipment to be mounted 20 is attached to the direct mounting fixture 10.

[0063] The third spring portion 223 is formed to extend in the vertical direction (Z-axis direction) by being folded back from the upper end of the second spring portion 222 toward the downward side. The second spring portion 222 and the third spring portion 223 are bent into an L-shape.

[0064] The third spring portion 223 is a plate, and its length in the vertical direction (Z-axis direction) is shorter than the lengths of the first spring portion 221 and the second spring portion 222 in the vertical direction (Z-axis direction). The third spring portion 223 is formed to extend in the width direction (Y-axis direction) from the upper end of the second spring portion 222. The mounting device 1 is attached to the mounting fixture 10 by the third spring portion 223 of the mounting spring 22 catching on the peripheral edge of the slit 124.

[0065] (Description of the state in which the equipment to be mounted 20 is attached to the surface-mount fixture 10) Figure 10 is a front cross-sectional view of the direct mounting device 1 according to the embodiment. When the equipment to be mounted 20 is attached to the direct mounting fixture 10, the main body 21 of the equipment to be mounted 20 is inserted through the bottom opening 131 of the bottom 13 of the direct mounting fixture 10, and the edge 211 of the main body 21 and the lower surface 13a on the downward side of the bottom 13 are in contact.

[0066] The mounting spring 22 of the equipment to be attached 20 is held in the width direction (Y-axis direction) by the first spring portion 221 and the second spring portion 222 being sandwiched between the main body 21 and the spring receiving portion 142 of the spring receiving fitting 14.

[0067] In the mounting spring 22, the angle formed by the first spring portion 221 and the second spring portion 222 is defined as angle θ (see Figures 8 and 10). In the direct mounting device 1, the mounting spring 22 is held between the main body 21 and the spring receiving portion 142 when the angle θ (see Figures 8 and 10) is smaller than the angle when the equipment to be mounted 20 is attached to the direct mounting device 10. The mounting spring 22 is positioned between the main body 21 and the spring receiving portion 142 with the space between the first spring portion 221 and the second spring portion 222 narrowed. The engagement between the main body 21 and the spring receiving portion 142 is strengthened by the restoring force that attempts to widen the space between the first spring portion 221 and the second spring portion 222.

[0068] As shown in Figure 10, when the equipment to be mounted 20 is attached to the direct mounting device 10, the bent portion 224 of the mounting spring 22 is positioned in the notch 132. If the direct mounting device 1 does not have the notch 132, the equipment to be mounted 20 may not be able to be removed from the bottom 13. By having the notch 132, the direct mounting device 1 can prevent the equipment to be mounted 20 from becoming stuck in place. In addition, by having the notch 132, the direct mounting device 1 can prevent the equipment to be mounted 20 from rotating.

[0069] As shown in Figure 10, when the equipment to be mounted 20 is attached to the mounting fixture 10, the third spring portion 223 of the mounting spring 22 of the equipment to be mounted 20 is inserted through the slit 124 of the main column portion 121. The third spring portion 223 is fitted into and engaged with the formed portion of the slit 124 and is held in place by the formed portion of the slit 124. The equipment to be mounted 20 is held in place by the mounting fixture 10 because the third spring portion 223 catches on the peripheral edge of the slit 124.

[0070] When the operator rotates the second spring portion 222 so as to press it toward the main body 21 around the turning point 224a between the first spring portion 221 and the second spring portion 222, the third spring portion 223 moves toward the main body 21 by moving upward and in the width direction, and disengages from the slit 124.

[0071] (Method for removing the equipment to be attached 20 from the direct-mount fixture 10) Figure 11 is a front view illustrating the removal of the equipment to be mounted 20 in the direct mounting device 1 according to the embodiment. Using Figures 11(a) to (c), the method for removing the equipment to be mounted 20 from the direct mounting fixture 10 in the direct mounting device 1 will be explained.

[0072] (1) First, the worker removes the main screw 121b that attaches the column main part 121 and the spring receiving connection part 143, as shown in Figure 11(a). (2) Next, the worker presses the second spring part 222 of the mounting spring 22 toward the main body 21, as shown in Figure 11(b). (3) At this time, the end of the second spring part 222 toward the third spring part 223 and the third spring part 223 move in an arc shape with the turning point 224a between the first spring part 221 and the second spring part 222 as the pivot point, moving toward the main body 21 in the upward direction (Z-axis direction) and the width direction (Y-axis direction).

[0073] (4) Due to the movement of the second spring portion 222 and the third spring portion 223, the third spring portion 223 disengages from the slit 124 and separates from the main column portion 121. (5) Once the third spring portion 223 disengages from the slit 124 and separates from the main column portion 121, the equipment to be mounted 20, together with the bottom portion 13, detaches from the mounting fixture 10, as shown in Figure 11(c). (6) When the worker pulls the equipment to be mounted 20 out of the mounting fixture 10, the equipment to be mounted 20 detaches from the mounting fixture 10 while passing through the bottom opening 131 of the bottom portion 13.

[0074] (Fall prevention mechanism for the attached equipment 20) Figure 12 is a front view illustrating the fall prevention effect of the direct mounting device 1 according to the embodiment. Figure 13 is an enlarged view of part B in Figure 12 of the direct mounting device 1 according to the embodiment. The relationship between the mounting spring 22 and the slit 124 in the fall prevention mechanism of the equipment to be mounted 20 will be explained using Figures 12 and 13.

[0075] (Fall prevention pattern #1) (1) In the direct mounting device 1, we will consider the case where the equipment to be mounted 20 is about to fall downwards through the bottom opening 131 of the bottom 13 due to vibration.

[0076] (2) When the equipment to be mounted 20 moves downward, the mounting spring 22 is pressed by the spring receiving portion 142 and deforms so that the angle θ (see Figures 8 and 10) becomes smaller compared to when the equipment to be mounted 20 is attached to the direct mounting fixture 10. The second spring portion 222 and the third spring portion 223 of the mounting spring 22 move toward the main body 21 in an arc shape toward the upward and widthwise directions, with the turning point 224a between the first spring portion 221 and the second spring portion 222 as the pivot point.

[0077] (3) The third spring portion 223 attempts to move upward and toward the main body 21 together with the second spring portion 222. However, because the attached equipment 20 attempts to move downward due to falling, the third spring portion 223 does not pass through the slit 124 in a direction that would cause it to move away from the slit 124, but instead gets caught on the peripheral edge of the slit 124.

[0078] (4) The equipment to be attached 20 is held by the main column portion 121 of the direct mounting fixture 10 because the third spring portion 223 catches on the peripheral edge of the slit 124, and can be prevented from falling without coming off the direct mounting fixture 10.

[0079] Even if the direct mounting device 1 is shaken from side to side due to vibration, the third spring portion 223 is firmly caught in the slit 124 by the elastic force of the mounting spring 22, so the equipment to be mounted 20 will not fall.

[0080] (Fall prevention pattern #2) (1) We will examine the case in which, due to vibration, the spring receiving connection part 143 of the spring receiving bracket 14 detaches from the main part 121 of the column, causing the bottom part 13 and the attached equipment 20 to fall.

[0081] (2) As the equipment to be attached 20 attempts to move downward due to the fall, the third spring portion 223 does not pass through the slit 124 in a direction that would cause it to detach from the slit 124, but moves downward and catches on the peripheral edge of the slit 124. Because the third spring portion 223 catches on the peripheral edge of the slit 124, the equipment to be attached 20 is held by the main column portion 121 of the direct mounting fixture 10, and is prevented from falling without detaching from the direct mounting fixture 10.

[0082] (Fall prevention pattern #3) (1) In the direct mounting device 1, we will consider the case where the equipment to be mounted 20 is about to fall downwards through the bottom opening 131 of the bottom 13 due to vibration.

[0083] (2) The mounting spring 22 is formed such that the width of the second spring portion 222 in the depth direction (X-axis direction) is longer than the length L between the pair of spring stoppers 144 as it moves from the turning point 224a side with the first spring portion 221 toward the third spring portion 223 side. When the equipment to be mounted 20 is about to fall, the direct mounting device 1 has the second spring portion 222 sandwiched between the pair of spring stoppers 144 and held in place by the pair of spring stoppers 144. As a result, the direct mounting device 1 has the equipment to be mounted 20 held in place by the bottom 13 of the direct mounting device 10 via the spring receiving fitting 14, thereby preventing the equipment to be mounted 20 from falling.

[0084] (Effects and effects of the direct mounting device 1) The mounting device 1 has a main body 21 and a pair of mounting springs 22 attached to the main body 21. The pair of mounting springs 22 are attached to the main body 21 and have a first spring portion 221 that extends from the top plate 11 side to the bottom portion 13 side, and a second spring portion 222 that is formed by folding back from the tip of the first spring portion 221 and contacts the spring receiving portion 142. The pair of mounting springs 22 also have a third spring portion 223 that is formed by folding back from the tip of the second spring portion 222 and is inserted into the slit 124 of the column portion 12.

[0085] Even if the equipment to be mounted 20 is about to fall from the mounting fixture 10, the third spring portion 223 moves downward, preventing it from coming out of the slit 124 and causing it to catch on the periphery of the slit 124. Therefore, the mounting device 1 can prevent the equipment to be mounted 20 from falling. When removing the equipment to be mounted 20 from the mounting fixture 10, the mounting device 1 can remove the equipment to be mounted 20 from the mounting fixture 10 by detaching the third spring portion 223 from the slit 124 before removing the equipment to be mounted 20 from the mounting fixture 10.

[0086] The mounting spring 22 is formed such that the width of the second spring portion 222 in the depth direction (X-axis direction) becomes longer than the length L between the pair of spring stoppers 144 as it moves from the turning point 224a side with the first spring portion 221 toward the third spring portion 223 side. When the equipment to be mounted 20 is about to fall, the direct mounting device 1 has the second spring portion 222 sandwiched between the pair of spring stoppers 144 and held in place by the pair of spring stoppers 144. As a result, the direct mounting device 1 can prevent the equipment to be mounted 20 from falling by holding it to the bottom 13 of the direct mounting device 10 via the spring receiving fitting 14.

[0087] The direct mounting fixture 10 has an opening 10a formed by the top plate 11, column portion 12, and bottom portion 13 in the depth direction (X-axis direction). Since the worker can operate the mounting spring 22 from the opening 10a, the worker can operate the second spring portion 222 while the equipment to be mounted 20 is attached to the direct mounting fixture 10, and by operating the second spring portion 222, the equipment to be mounted 20 can be removed from the direct mounting fixture 10.

[0088] The configurations shown in the above embodiments are merely examples, and can be combined with other known technologies. It is also possible to omit or modify parts of the configuration without departing from the gist of the invention. [Explanation of Symbols]
