Description

  The present invention mainly has a lighting angle and other fixtures fixed on a fixing part such as a top plate such as a wall surface, a showcase, a display shelf, etc. More particularly, the present invention relates to an instrument fixture that can change and adjust its orientation.

  Conventionally, the appliances targeted by the present invention are, for example, a lead illuminator. For example, the lower wall of the main body frame is directly connected to the fixing portion by screws or clip structures (the structure shown in the figure is screwed). It was a common way of attaching.

  When this direct attachment method was adopted, the emission direction of the lead light source portion with respect to the main body frame of the illuminating lamp could be changed only within the range of the swing angle as originally designed. Although it is easy to make the lead light source portion swingable within a range of 360 degrees, if the lead light source part is swung to a certain range or more, the emitted light emitted from the lead light source is shielded by the main body frame, and 360 degrees. There is no meaning of swinging, and generally a structure that swings within a predetermined range is adopted. Therefore, it is impossible to irradiate the range and direction beyond the rocking angle inherent in the instrument, and the consumer desires a way to change the irradiation range and direction beyond the original rocking range. It was rare.

  The present inventor has intensively studied to meet the demands of this consumer. First, trial and error were repeated to improve the structure of the device itself, but this resulted in a major change in the manufacturing process so far, resulting in an increase in cost and was not desirable. Therefore, as a result of searching for a means to change the irradiation range and direction beyond the original swing range, although the equipment itself can be used as it is without changing special specifications, We have developed a satisfactory method and will provide it here.

  Therefore, the purpose of this device is to install instruments that can extend the swing range beyond the original swing range of the instrument, while the instrument itself can be used without changing the specifications. It is in providing tools.

In order to achieve the above-mentioned object, a main frame composed of an instrument fixture according to the present invention, a base plate abutted and fixed to a fixing portion, and a support leg integrally raised from its right and left edges, and the main frame A mounting frame provided with a support element for projecting integrally from the other side toward the opposite side of the support leg and holding the instrument body. A support shaft structure that pivotally supports the main frame and the mounting frame on the extending end side of each supporting leg, and an engaging projection provided on the overlapping portion and the engaging projection. It is constituted by a change structure consisting of a plurality of engagement holes for releasably engaging the part or a rotation range change structure consisting of a change structure which can clamp and release the overlapping portion .

  In the fixture mounting apparatus configured as described above, first, the main frame is mounted on the fixed portion, and then the fixture is mounted on the mounting frame. The direction of the mounting frame can be freely changed within a desired angle range with respect to the main frame, and the swinging of the mounting frame acts as the inclination of the body frame of the instruments. Therefore, for example, unlike the conventional type in which the main body frame of the illuminating lamp is directly attached to the fixed portion, the main body frame corresponding to the amount of rotation by the mounting frame is within the swing range of the original lead light source that the instrument originally has. Inclination is added. In this manner, the tilt amount of the main body frame of the illuminating lamp can be added to the original swing amount of the lead light source, and the irradiation range can be expanded. Incidentally, if the swing range can be expanded within a range of 50 degrees on one side as in the embodiment, the swing range is added to 140 degrees on one side by adding this 50 degrees in addition to approximately 90 degrees on one side of the original instrument. Can be expanded.

  The fixture fixture of the present invention is different from the conventional type in which the main body frame of the illuminating lamp is directly attached to the fixed portion, etc., in a range in which the rotation amount of the mounting frame is added to the original swing range of the fixture. Since the irradiation range can be expanded, the device itself can be used without changing the specifications, but the irradiation range and direction can be changed beyond the original swing range while the conventional one can be used. . Therefore, unlike the conventional type in which the main body of the instrument is directly attached to the fixed part, the instrument itself does not require any special specification change, and the original instrument can be used while being used as usual. The swing range can be expanded beyond the range of motion. Therefore, it can also be provided at a low price.

In the above configuration, according to the present invention, as described in claim 2, it is desirable that the instrument is a lead illumination lamp in which a lead light source is attached to the main body frame so as to be rotatable within a predetermined range.
This is because the amount of light emitted from the lead light source can be effectively irradiated 100% without being blocked by the instrument body.

According to a third aspect of the present invention , the rotation range changing structure includes an engaging protrusion provided in the overlapping portion and a plurality of engaging holes for detachably engaging the engaging protrusion. the composed either stepless change structure is desirable to freely clamping and releasing the clamping of the specific changes structure or the overlapping portions.
According to the stepwise change structure, the angle change is selective and the change work is easy, and the stepless change structure is convenient for enabling a subtle position change.

The support element for supporting the instrument is integrally raised from the other side different from the two sides projecting the support legs of the mounting frame toward the opposite side of the support legs. It is desirable to be a pair of clip pieces that elastically grip the main body from the left and right.
This is because the attachment of the instrument body is very simple.

According to a fifth aspect of the present invention, the support element for supporting the instrument is a pair of protrusions integrally projecting from another side different from the side where the support leg of the mounting frame protrudes toward the opposite side of the support leg. It is preferable that the instrument main body is tightened and gripped by screwing the screw into the support plate and at least one of the support plates.
This is because it is particularly effective for holding large instruments.

According to a sixth aspect of the present invention, it is desirable that the support shaft structure is any one of a fitting metal or a bolt / nut and a cylinder frame fitted on the bolt.
This is because the clasp has a simple structure and can be manufactured inexpensively. Further, it is particularly effective for a stepless angle change in the case of a structure constituted by a bolt / nut and a cylinder frame fitted on the bolt.

According to the seventh aspect of the present invention, the stepwise rotation range changing structure is configured such that the engagement protrusion provided on one surface side of the main frame supporting leg and the mounting frame supporting leg extending end side facing each other. And a plurality of engagement holes for releasably engaging the engagement protrusions on a virtual concentric circle centered on the support shaft structure on the other side surface.
This is because the angle can be changed accurately and quickly with a simple structure.

As described in claim 8, the stepless rotation range changing structure includes a screw structure including a bolt having a head and a wing nut screwed into a screw portion of the bolt, and an extension of the support leg. The cylindrical frame has a length equivalent to the interval between the overlapping portions on the end side and is externally fitted to the bolt. The bolt is one of the overlapping portions of the main frame support leg and the mounting frame support leg. The head is brought into contact with the outer surface of the side, and the mounting frame is rotatably supported with respect to the main frame through the overlapping portions of the main frame supporting leg and the mounting frame supporting leg, and the wing nut is tightened. Therefore, it is desirable that the overlapping portion of the head portion and the tubular frame is clamped and the overlapping portion of the other portion is clamped and clamped between the tubular frame and the wing nut.
This is because the stepless angle change can be performed accurately and reliably.

It is an external view of the lead illumination lamp which is an example of the suitable instruments applied to this invention instrument mounting fixture. It is an expanded sectional view of another support element applied to the device fixture of this invention.

  Hereinafter, the case where the embodiment of the present invention is applied to a fixture for a lead illumination lamp of a type in which the lead light source rotates within a predetermined range will be described.

  As shown in FIGS. 1 to 5, the fixture 1 basically includes a main frame 2 that is in contact with and fixed to a fixing portion B such as a wall surface, and a support shaft structure 3 with respect to the main frame 2. And an attachment frame 5 that is supported so as to be pivotally fixed and can hold the instrument body 4.

  As shown in FIGS. 1 to 4, the main frame 2 that is abutted and fixed to the fixing part B extends integrally with the substrate 20 made of a metal and formed into a rectangular flat plate, and its left and right edges. An end (top) 21 is formed with a plate portion 22 having an irregular side triangle shape (in the example shown, a right triangle) formed in an arc, and the plate portion 22 having an irregular side triangle shape is formed on one side of the substrate 20. The support leg 23 is configured by bending up at a right angle and starting up. A through hole 24 (FIG. 3) is formed near the top portion 21 of the pair of left and right support legs 23. The arc of the top portion 21 is formed as a partial arc centered on the through hole 24. The through hole 24 is provided at a position corresponding to a portion that is biased to approximately a quarter position from the middle of the full length of the edge where the support legs 23 of the substrate 20 are connected to one end side. Furthermore, a screw is placed at a position deviated from the middle of the entire length of the continuous edge of the substrate 20 toward the other end side to about a half position and at the middle position in the width direction of the substrate 20. A hole 25 is provided. The screw hole 25 is used when the main frame 2 is screwed to the fixed portion B, for example.

  1-4, the mounting frame 5 is integrally connected to the left and right edges of the base plate 50 made of a metal and formed into a rectangular flat plate, and the extending end (top portion) 51 is an arc. The isosceles triangular plate portion 52 is formed on the base plate 50. The isosceles triangular plate portion 52 is bent at a right angle to one side of the substrate 50 and raised to form a support leg 53. Has been. A through hole 54 (FIG. 3) is formed near the top 51 of the pair of left and right support legs 53. The arc of the top 51 is formed as a partial arc centered on the through hole 54. The through hole 54 is provided at a position corresponding to the middle of the entire length of the edge where the support legs 53 of the substrate 50 are connected. Further, from the other two sides where the substrate 50 support leg 55 is not provided, clip pieces 55 which are examples of support elements are formed by bending toward the side opposite to the projecting direction of the support legs 53. The clip pieces 55 are first bent from the edge of the substrate 50 at a substantially right angle with respect to the substrate 50 and hang down, and the intermediate portions are close to each other following the vertical portion 55A. The holding portion 55B is configured to be bent, and further includes a guide portion 55C that is formed by bending the free end side outward in a flared shape. Since the sandwiching portion 55B has a narrow width S, the instrument body 4 can be resiliently sandwiched at this portion.

  The shape of the support leg 20 of the main frame 2 is a right triangle, and the center position of the fitting 6 that is the center of rotation of the support frame 20 is substantially from the middle of the entire length of the edge where the support legs 23 of the substrate 20 are connected to one end side. The reason why the screw hole 25 is biased further away from the center of rotation of the main frame 2 is provided at a position corresponding to a portion biased to a quarter position, as will be described later. If the main frame 2 is rotated in a direction in which the screw hole 25 side is further away from the mounting frame 5, the relative distance between the screw hole 25 and the mounting frame 5 becomes as large as possible, and screw screwing is performed. This is because the work can be performed using a wide space OS and the convenience of the work is achieved (see FIG. 4).

Next, the structure of the support shaft structure 3 is as follows.
The distance between the support legs 23 of the main frame 2 is slightly narrower than the distance between the support legs 53 of the attachment frame 5, and the support legs 53 of the attachment frame 5 are assembled together so as to sandwich the support legs 23 of the main frame 2 from the outside. . And the clasp metal 6 is inserted in the pair of mutual through holes 24 and 54, and these are clamped. Thus, the main frame 2 and the mounting frame 5 are assembled so as to be rotatable about a virtual axis P connecting the centers of the pair of fittings 6.
As a result, the mounting frame 5 is rotatable with respect to the main frame 2.

And the rotation range change structure 7 for making the attachment frame 5 freely rotatable with respect to the main frame 2 is configured as follows.
That is, as shown in FIGS. 1 to 4, particularly FIG. 3, a portion of the support leg 23 of the main frame 2 that overlaps the support leg 53 of the mounting frame 5 is projected toward the support leg 53 side of the mounting frame 5. A semicircular engagement protrusion 71 is provided integrally. The engagement protrusion 71 is provided on the side of the substrate 20 with respect to the fitting 6 of the main frame 2. On the other hand, a plurality of (three in the illustrated example) semicircular shapes projecting toward the support leg 23 side of the main frame 2 on the part of the support leg 53 of the mounting frame 5 that overlaps the support leg 23 of the main frame 2. The engaging recess 72 is integrally provided. The engaging recess 72 is provided closer to the substrate 50 than the fitting 6 of the support leg 53 of the mounting frame 5. The engagement protrusion 71 and the engagement recess 72 are both provided on a partial arc that is equidistant from the center of the fitting 6, and a plurality of engagements are achieved by the rotation of the mounting frame 5 relative to the main frame 2. The recess 72 is configured to selectively engage with the engagement protrusion 71. Further, the engaging recesses 72 are arranged at equal intervals on the left and right sides with the left and right engaging recesses 72 in between. The included angle between the imaginary line segments connecting each engagement recess 72 and the center of the fitting 6 is set to 50 degrees. Therefore, the attachment frame 5 can be rotated by 50 degrees from the horizontal position to the left and right with respect to the main frame 2.

Here, the outline | summary is demonstrated based on description of FIG. 7 about the lead illumination lamp as an example of the instrument main body suitably applied to this invention.
The lead illuminating lamp 40 is basically an elongated die made of aluminum die-cast, and has an illuminating lamp main body 41 made of a cylindrical body having a rectangular cross section with walls 2 around the four sides, and openings at both ends in the longitudinal direction of the illuminating lamp main body 41. A synthetic resin end cap 42 to be closed, a support member 43 integrally raised upward from the end cap 42, and a plurality of LED bodies 44 (see FIG. 5) mounted in a line along the longitudinal direction. A substrate 45, a transparent translucent cover body 46 covering the upper side of the LED bodies 44 arranged in a row, specifically a transparent and shape-retaining synthetic resin cover body 46, and the printed circuit board 45 and the cover body 46 are held. And a synthetic resin holder 47 for connecting the support member 43 to the support member 43. Further, the holding body 47 is long along the longitudinal direction of the printed circuit board 45 and has a concave holding shape in which the upper part and both ends in the longitudinal direction are open, and the longitudinal direction of the holding body 20 Are respectively connected to the both ends of the printed circuit board 8 and can be swung around an axis P along the longitudinal direction of the printed circuit board 8 and can be held by the support member 43 so as to be able to hold a position at an arbitrary swinging position. A member 48 is provided. In FIG. 7, reference numeral 49 denotes an electric cord connected to an AC 100V power source.

Next, the operation of the fixture 1 according to the present invention configured as described above will be described with reference to FIGS.
First, as shown in FIG. 4, the main frame 2 is rotated in a direction away from the mounting frame 5 around the virtual rotation axis P by the fitting 6 on the side where the screw hole 25 is provided, The engagement protrusion 72 on the main frame 2 side is engaged with the engagement recess 72 to maintain the rotation position. By rotating both the frames 2 and 5, a space between the screw hole 25 and the substrate 50 of the mounting frame 5 is largely opened, and a wide space OS is obtained. Thereafter, the main frame 2 is screwed to the fixed portion B with a tool or the like as appropriate. Depending on the length of the illuminating lamp main body 41 of the reed illuminating lamp 40, the number of attachments 1 is appropriately selected. Next, as shown in FIGS. 1 and 5, the illuminating lamp body 41 is pushed between the clip pieces 55 from the open side of the clip piece 55 between the pair of clip pieces 55 of the mounting frame 5. By this pushing, first, the guide portion 55C performs smoothly, but both the clip pieces 55 spread outward against the elastic restoring force, and then the narrow portion (slit portion) S ′ of the illuminating lamp main body 41. The sandwiching portion 55B is fitted by elastic restoring force, and the illumination lamp main body 41 is firmly sandwiched and fixed between the clip pieces 55, and the setting of the lead illumination lamp 40 is completed. In addition, it is desirable that the narrow part S ′ is provided in the illuminating lamp main body 41 because it is possible to perform more preferable clamping and fixing. It goes without saying that the device lamp can be fixed to the original illumination lamp body 41 by the elastic clamping force of 55.

Next, in changing the irradiation position of the lead illuminating lamp 40, basically, as a first step, the LED body 44 is rotated with respect to the illuminating lamp main body 41 and changed appropriately.
However, when it is desired to change the irradiation position beyond that, the illumination lamp main body 41 is supported by both hands, and as shown in FIG. 5, the illumination is performed in a necessary direction around the virtual axis P of the fitting 6. The attachment frame 5 is rotated with respect to the main frame 2 together with the lamp body 41. In this embodiment structure, the rotation angle can be changed between the center normal attachment position and the two rotation positions rotated by 50 degrees to the left and right. Therefore, the direction can be freely changed to the three positions as necessary. Since the number of the engaging recesses 72 can be appropriately set in advance in the manufacturing stage as necessary, it is possible to obtain a product having not only three positions but also more rotational positions as in the above-described embodiment. Needless to say, you can.

  Note that, in the left and right movement positions shown in FIG. 5, a situation is shown in which the LED bodies 44 are at positions that are most outward. In this embodiment, the irradiation direction can be adjusted within a range of about 280 degrees at the maximum.

  Thus, according to the structure of the above-described embodiment, the reed illuminating lamp 40 itself can be used as it is without any special specification change, but the irradiation range beyond the original swinging range can be used. The direction can be changed easily. Therefore, since only the fixtures as described above are prepared, the total can be provided at a very low price.

Next, Example 2 will be described in detail.
The second embodiment provides a structure 8 that can change and fix the rotation range in a stepless manner instead of the stepwise rotation structure shown in the first embodiment when the mounting frame 5 is rotated with respect to the main frame 2. To do.

As shown in FIG. 6, the stepless rotation range changing structure 8 basically includes a screw structure 9 and a cylindrical frame 10 that is externally fitted to the screw structure 9.
The screw structure 9 includes a bolt 82 having a head 91 and a wing nut 84 that is screwed into a screw portion 83 of the bolt 82. The bolt 82 passes through the through hole 24 on the main frame 2 side and the through hole 54 on the mounting frame 5 side, respectively, and the outer surface on one side of the overlapping part of the support leg 23 of the main frame 2 and the support leg 53 of the mounting frame 5. The head 91 is brought into contact with the support frame 23, and the mounting frame 5 is rotatably supported with respect to the main frame 2 through the overlapping portions of the support leg 23 of the main frame 2 and the support leg 53 of the mounting frame 5. The cylinder frame 10 is inserted between the overlapping portions in a posture in which the tube frame 10 is fitted to the bolt 82. Accordingly, by tightening the wing nut 84, one overlapping portion between the head 81 and the tubular frame 8 is tightened, and the other overlapping portion is tightened between the tubular frame 8 and the wing nut 84. Thus, the attachment frame 5 is clamped and fixed with respect to the main frame 2 while maintaining a predetermined rotation angle.

When the angle of the mounting frame 5 is changed with respect to the main frame 2, the tightening by the wing nut 84 is loosened until the mounting frame 5 can freely rotate with respect to the main frame 2. Next, the mounting frame 5 is rotated at the required angle. Finally, with the angle maintained, the wing nut 84 is tightened, and the mounting frame 5 is clamped and fixed to the main frame 2 by the cooperation of the cylinder frame 82 to maintain the position after the desired angle change.

  According to the stepless rotation range changing structure 8 according to the second embodiment, the stepless angle change can be performed accurately and reliably, quickly and easily, and the irradiation direction can be adjusted very delicately. Fine irradiation can be performed on any part of the irradiation position.

Next, FIG. 8 illustrates another embodiment of the support element, in which a screw 11 is employed instead of the clip piece 55.
Specifically, a pair of flat support plates 12 project straightly from one side that is different from the other side from which the support leg 53 of the mounting frame 5 protrudes toward the opposite side of the support leg 53. The screw 11 is screwed onto at least one of the support plates 12 from the outside, and the illumination lamp main body 41 is tightened and gripped by screwing the screw 11. In the figure, reference numeral 13 denotes a nut integrally fixed to the outer surface of the support plate 12 in order to ensure the screwing action of the screw 11. Although only one side is provided in the figure, it is also possible to provide this support element on both the left and right sides. Enables stronger retention.

  According to this structure, the illumination lamp main body 41 can be firmly clamped and fixed even for a type in which the narrow portion S ′ is not provided, and the heavy illumination lamp main body is clamped and fixed. Is also effective.

  The fixture attachment described above is not only a lead illumination lamp, but is a variety of fixtures that are inherently capable of changing the angle, and further to fixtures that require a large or fine change in the rotation angle. By applying it, it is possible to cope with even a subtle angle change that is larger than the range of the original angle change.
