Description

  The present invention relates to a lighting device fixed to another object, and particularly to a lighting device fixed to a bed or the like.

Conventionally, there has been a bed in which a lighting device is incorporated in a headboard portion (see, for example, Patent Document 1). However, the bed or pipe bed in which the headboard is simply a thick plate does not normally have a lighting device incorporated therein. Therefore, when using such a bed, the user has to prepare a separate lighting device. And the thing of the structure which attaches an illuminating device to the clamp stand for clamping the said headboard etc. is known as an illuminating device used for such a use (for example, refer patent document 1). And such an illuminating device can make the said headboard etc. adjoin to a wall by making it not project the clamping bolt for clamping the said clamp stand.

  However, in such an illuminating device, although the amount of protrusion can be reduced, the fastening bolt always protrudes, so that the headboard or the like to which the clamp base of the illuminating device is attached is brought close to the wall. There are limits to this. Therefore, when using such an illuminating device, it is necessary to provide a gap corresponding to at least the protruding amount of the tightening bolt between the wall and the headboard to which the clamp base is attached. Moreover, when attaching such an illuminating device to the said headboard etc., the space for turning the said fastening bolt by hand is required behind the said headboard etc. Therefore, in practice, it is necessary to leave a large gap between the headboard to which the clamp table is attached and the wall. In addition, after attaching the said clamp stand to the said head board etc., the method of moving a bed and bringing the head board etc. to which the said clamp stand was attached close to a wall is also considered. However, in this case, if the clamp base is loosened, there arises a problem that the clamping bolt must be retightened by moving the bed each time. Further, when the bed is moved, if the clamping bolt is caused to collide with the wall, there is a problem that the wall is damaged. If the tightening bolt is provided on the front side, such a problem does not occur, but not only an aesthetic problem occurs, but also there is a possibility that clothes or the like may be caught on the tightening bolt.

  An object of the present invention is to solve the above problems and to provide an illuminating device capable of bringing a headboard or the like as close as possible to a wall when attached to the headboard or the like.

  The lighting device according to claim 1 of the present invention is an illumination device having an L-shaped main body, a lamp attached to the main body, and a fixing portion for fixing the main body to a fixed portion. An L-shaped metal fitting having a holding part and a sliding part; a pressing part facing the holding part of the metal fitting; and a biasing means for biasing the pressing part toward the clamping part; It has a ratchet mechanism that enables movement of the metal fitting to the pressing portion side and prevents movement to the counter pressing portion side.

  The lighting device according to claim 2 of the present invention is the lighting device according to claim 1, wherein the rear end of the holding portion is the same as the rear end of the main body with the holding portion of the metal fitting closest to the pressing portion. Alternatively, it is configured so as to be located behind the rear end of the main body.

  According to a third aspect of the present invention, in the lighting device according to the first or second aspect, a spacer is detachably attached to the holding portion side of the pressing portion.

  Furthermore, the lighting device according to a fourth aspect of the present invention is the lighting device according to the first to third aspects, wherein a protective member is provided on a surface of the clamping portion on the side opposite to the pressing portion.

  The illuminating device according to claim 1 of the present invention is configured as described above, and is arranged so as to sandwich a headboard or the like of the bed between the holding portion of the metal fitting and the pressing portion, and the pressing portion and the pressing portion. By relatively moving the metal fitting and the main body so as to approach each other, the headboard or the like is clamped by the pressing portion biased by the biasing means and the clamping portion. In this manner, the lighting device is attached to the headboard or the like by sandwiching the headboard or the like between the pressing portion and the sandwiching portion. Further, since the movement of the metal fitting to the side opposite to the pressing portion is blocked by the ratchet mechanism, a conventionally used tightening bolt is not necessary, and other than the metal fitting projects to the back side of the headboard or the like. There is nothing to do. As a result, the distance between the headboard for mounting the lighting device and the wall can be reduced.

  In addition, in the state where the holding part of the metal fitting is closest to the pressing part, the rear end of the main body does not protrude rearward from the rear end of the holding part, so a headboard for attaching the lighting device, etc. You can get as close as possible to the wall.

  Further, since the spacer is detachably attached to the pressing portion side of the pressing portion, even when the headboard is thin, the spacer is attached to the pressing portion, and the headboard is sandwiched between the spacer and the clamping portion. Thus, the illuminating device can be securely attached to the headboard or the like by fully utilizing the urging force of the urging means.

  Further, by providing a protective member on the surface of the clamping part on the side opposite to the pressing part, even if the clamping part is pressed against the wall, the clamping part can be prevented from damaging the wall. As a result, even if the gap is provided by the thickness of the clamping portion between the headboard or the like and the wall, the clamping portion is inserted into the gap and the body is pressed against the headboard or the like. The lighting device can be attached to a headboard or the like without being damaged.

  Next, the operation of the present invention will be described. When attaching the lighting device 1 to a headboard H of a bed or the like, first, the user puts his finger on the finger hooking portion 23 of the ratchet arm 22 and moves the ratchet arm 22 against the urging force of the coil spring 25. Pull up. As described above, when the ratchet arm 22 is pulled upward, the claw portion 24 moves upward and the claw portion 24 is detached from the locking hole 31. In this way, the claw portion 24 is removed from the locking hole 31, so that the sliding portion 29 of the L-shaped metal fitting 28 moves forward and backward with respect to the horizontal portion 7 of the casing 5 of the main body 2. It can move in both directions. In this state, the user moves the L-shaped bracket 28 rearward, and determines the distance from the anti-slip sheet 12 of the pressing portion 10 to the anti-slip sheet 42 of the sandwiching portion 30 of the L-shaped bracket 28 by the headboard H. After the thickness T becomes larger than the thickness T, the finger is released from the finger hook portion 23. As a result, the lighting device 1 can be attached to the headboard H or the like.

  Then, after the headboard H or the like is sandwiched between the pressing unit 10 and the clamping unit 30, the main body 2 is pressed against the headboard H or the like while supporting the clamping unit 30 so as not to move. At this time, the sliding portion 29 of the L-shaped metal fitting 28 moves forward relative to the horizontal portion 7. When the sliding portion 29 is moved forward relative to the horizontal portion 7, the rear upper end edge of the locking hole 31 contacting the inclined surface 24 </ b> B is the claw portion 24, that is, the ratchet arm. 22 is pushed upward, even if the claw portion 24 is engaged with the locking hole 31, the sliding portion 29 of the L-shaped metal fitting 28 is relatively forward with respect to the horizontal portion 7. It is movable. Then, from the state where the anti-slip sheet 12 of the pressing portion 10 is in contact with the front surface of the headboard H or the like, the pressing portion 10 is further pressed against the headboard H or the like so that the pressing portion 10 It moves to the front, that is, the anti-clamping portion 30 side against the urging force. When the user releases his hand from this state, the pressing portion 10 is pressed against the front surface of the headboard H or the like by the biasing force of the coil spring 11. On the other hand, the sliding portion 29 of the L-shaped metal fitting 28 is in a state where the vertical surface 24A of the claw portion 24 is in contact with the front edge of the locking hole 31, so It becomes impossible to move backward. Accordingly, the headboard H and the like are clamped by the pressing portion 10 and the clamping portion 30 by the urging force of the coil spring 11, so that the lighting device 1 is attached to the headboard H and the like.

  In addition, between the rear surface of the headboard H and the wall W or the like, the holding part 30 with the anti-slip sheet 33 attached is provided with a minimum gap into which the holding part 30 can be inserted. The lighting device 1 can be attached to the headboard H or the like without moving the bed or the like simply by inserting the main body 2 and pressing the main body 2 against the headboard H or the like.
