Description

  The present invention relates to an embedded lighting fixture.

  2. Description of the Related Art Conventionally, there has been known an embedded lighting fixture that is installed by being embedded in a mounting hole formed in a mounting wall portion such as a ceiling. Further, as this type of embedded lighting fixture, an appliance main body in which an opening for emitting light is formed in the lower part, a light source provided inside the appliance main body, and an outer peripheral edge of the opening are formed. There is known a device including a flange portion and a mounting spring portion as a fixing means for the mounting wall portion (see, for example, Patent Document 1). A plurality of attachment spring portions are disposed in the circumferential direction of the flange portion, and are formed obliquely upward from above the flange portion.

  The procedure for installing an embedded lighting fixture with a mounting spring on the mounting wall is to first squeeze each mounting spring in the direction of the center of the fixture with your fingers against the elastic force of the mounting spring. In the state, the instrument body and each mounting spring part are inserted into the mounting holes. Therefore, when the finger that has narrowed each attachment spring portion is released, each attachment spring portion comes into contact with the edge of the attachment hole. When the instrument body is pushed upward, each attachment spring portion elastically recovers and expands while each attachment spring portion abuts against the edge of the attachment hole. Then, due to the elastic urging force that the mounting spring portion further expands, the fixture body is pulled upward, the flange portion is in pressure contact with the mounting wall portion, and the embedded lighting fixture is attached. It is installed on the wall.

  On the other hand, when removing the embedded luminaire from the mounting wall, such as when replacing the embedded luminaire, the instrument body is pulled down against the urging force of the mounting spring section, and the instrument body and each mounting spring section Can be pulled out of the mounting hole. However, when the embedded lighting fixture is installed on the mounting wall, the flange is pressed against the mounting wall by the urging force of the mounting spring, and a fingertip is inserted between the flange and the mounting wall. It cannot be pulled down with.

  For this reason, first insert the fingers of both hands into the opening of the instrument body to hold the instrument body's inner surface (reflective surface) to the left and right, and hold it against the urging force of the mounting spring. Pull down. Then, a gap into which the fingertip is inserted is formed between the flange portion and the mounting wall portion, and this gap serves as a trigger for holding the outer edge portion of the flange portion. When the outer edge portion of the flange portion is held by inserting the fingertip into the gap and the instrument body is further pulled down, each attachment spring portion is gradually narrowed while coming into contact with the edge portion of the attachment hole. When the spring is pulled down to some extent, each mounting spring is squeezed in the direction of the center of the instrument body with your fingers against the elastic force of the mounting spring, and in this state, the instrument body and each mounting spring are pulled out of the mounting hole. The embedded luminaire is removed from the mounting wall.

  In addition, when the instrument body is pulled down and held by pushing the inner surface (reflective surface) of the instrument body left and right, depending on which part of the instrument body inner surface (reflective surface) is held, The force required to pull down is different. That is, the influence of the strength of the attachment spring portion is strong in the region close to the attachment spring portion, and the influence of the strength of the attachment spring portion is relatively weak in the region separated from the attachment spring portion. For this reason, when comparing the force required for pulling down the instrument body between the case where the region close to the attachment spring portion is held and the case where the region separated from the attachment spring portion is held, the region close to the attachment spring portion is The holding force requires a larger force than when holding the region separated from the mounting spring portion.

Further, the force required for pulling down the instrument body varies depending on the thickness of the mounting wall. The mounting spring part of the embedded luminaire can accommodate from a thin mounting wall part (for example, 5 mm) to a thick mounting wall part (for example, 25 mm). The degree of expansion of the mounting spring part in the state is different. In the case of a thin mounting wall part, the mounting spring part is greatly expanded, so a large force is required to pull down the instrument body. Therefore, the instrument body can be pulled down with a small force.

Each hook portion 71 is formed independently. Moreover, the area | region in which the hook part 71 is formed should just have the width | variety of the grade which can hang a fingertip, for example, is comparable as the width | variety of the main attachment spring part 61 or the sub attachment spring part 62 It forms in the area | region of width | variety.

  In addition, although the hook part 71 was formed for every site | part most distant from each of the adjacent main attachment spring part 61 and the sub attachment spring part 62, it is not limited to this, For example, it should be provided in at least one place. That's fine.

  The cross-sectional shape of the hook portion 71 is formed to be a step as shown in FIG. Further, the shape in plan view is a shape formed at a constant width on the outer edge portion of the upper portion of the flange portion 41 as shown in FIG. By forming in this way, the hook 71 does not come into contact with the ceiling even when the embedded lighting fixture 11 is installed on the ceiling, and therefore a gap for placing the tip of a finger between the flange 41 and the ceiling. Can be secured. The hook portion 71 may be formed by cutting means at the outer edge portion of the upper portion of the flange portion 41 or may be formed when the frame body 31 is cast.
