Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a mounting bracket used for mounting various gloves to a fixed frame having a light source section in a ceiling-fixed lighting fixture, for example. It is a thing.

"Prior Art" Various types of lighting fixtures fixed to the ceiling of a building have been conventionally provided, but basically, a fixed frame having a light source part and a removable frame Made of glass gloves that can be attached.

In the conventional case, when attaching the globe to the fixed frame having the light source section, the following two methods are generally widely adopted.

As shown in FIG. 7A, the first mounting method is to form a plurality of screw screw holes 3 on the side of the fixed frame 1 fixed to the ceiling 8 with screws, while the upper end on the side of the glove 2 is formed. The engagement recess 4 is integrally formed on the outer side of the edge, and the upper end of the globe 2 is inserted into the fixed frame 1 to obtain a state in which the screw 5 screwed into each hole 3 is turned to turn the The globe 2 is detachably attached to the fixed frame 1 by engaging the tip of the screw 5 into the engagement recess 4 on the globe 2 side.

In the second mounting method, as shown in FIG. 2B, the female screw portion 6 is integrally formed inside the lower portion of the fixed frame 1, and the male screw portion 7 is integrally formed outside the upper end edge of the globe 2. The globe 2 is detachably attached to the fixed frame 1 by screwing the male and female screw portions 6 and 7 together.

"Problems to be solved by the invention" However, in the former method, since the head of the screw 5 is located outside the fixed frame 1, it goes without saying that the appearance is spoiled. Since the use of No. 5 requires complicated screwing work individually at several places when attaching and detaching the glove 2, it cannot be denied that the work becomes troublesome.

Moreover, according to this method, the tip of the screw 5 is simply engaged in the engaging recess 4 formed on the outer side of the upper edge of the globe 2, so that the supporting force of the globe 2 is naturally weakened. In particular, if there are variations in dimensions or if the screws 5 are loosened, the attachment state of the globe 2 becomes extremely unstable, and the globe 2 easily falls from the fixed frame 1 causing an unexpected accident. It had a big problem.

Moreover, since the fixed frame 1 of a normal lighting fixture is formed of a metal material such as stainless steel and the globe 2 is integrally formed of a glass material, the thermal expansion coefficients of the fixed frame 1 and the globe 2 are naturally different. , In the former method, since it is not possible to absorb the difference in the coefficient of thermal expansion, from this point as well,
It cannot be denied that the attachment state of the globe 2 becomes unstable.

In the latter method, the female screw portion 6 of the fixed frame 1 is attached to the glove 2
Since the glove 2 can be attached only by screwing the male screw part 7 of the above, the problem of workability of the former can be improved to some extent, but conversely, the female screw part 6 of the fixed frame 1 and the male part of the glove 2 can be reversed. Since high precision is required for processing the screw portion 7, the processing surface becomes very difficult this time, and a problem that the shape of the fixed frame 1 and the glove 2 is limited to a round shape is newly introduced. is doing.

Moreover, as described above, since the glove 2 is generally made of glass, it is technically difficult to integrally form the male screw portion 7 with high accuracy on the glass glove 2. Even in this latter method, there is a big problem that the glove 2 easily falls from the fixed frame 1 due to variations in the dimensions of the both 6 and 7 resulting in an unexpected accident. It was

Further, particularly in the latter method, if the screw parts 6 and 7 cannot be machined with high accuracy, the glass glove 2 may be damaged during screwing in addition to the drop of the glove 2. I also had it. Needless to say, the latter method cannot absorb the difference in the coefficient of thermal expansion.

Therefore, for example, Japanese Utility Model Publication No. 38-21376 and Japanese Unexamined Patent Publication No. 49-134.
A dedicated mounting bracket shown in Japanese Patent No. 190 has been proposed.

The former mounting bracket adopts a structure in which the support claws that receive spring pressure and project outwards are used to support the glove, and basically, when mounting / removing the glove,
Since it suffices to make this support claw appear and disappear, it is possible to improve workability, but when attaching the glove to the fixed frame, push the glove up over the support claw and the support claw will be spring-loaded. Since it suddenly projects outward, there is a risk that the edge of the glove will be damaged due to this, and it is also expected to absorb structural variations and dimensional variations and differences in the coefficient of thermal expansion. There wasn't.

In addition, the latter mounting brackets individually lock the gloves to the left and right mounting brackets that are fixed facing the fixing frame,
It is not necessary to worry about the damage to the glove side as described above because it is premised that the locking is released individually, but conversely, such a premise structure causes the work of attaching and removing the glove to be done. I couldn't do it with a single touch, so I could hardly hope to improve workability.

"Means for Solving the Problem" The present invention was developed in order to effectively solve such a conventional problem, and is a mounting metal fitting for removably mounting a mounting component to an attached body. Based on the above, a metal fitting base fixed to the attached body side, a movable shaft movably supported by the metal fitting base, a spring member for urging the movable shaft in a predetermined direction, and a connecting member for the movable shaft. And a guide member that guides the up-and-down movement of the lock member, and the metal fitting base is a box-like body having one end face opening, and the movable shaft is provided on both side walls thereof. Of the guide elongated hole is formed in the guide elongated hole, and the movable shaft is biased in the opening direction by the spring pressure of the spring member while the lock member is attached to the lower end portion on the mounting component side. The plate-like body is provided with an engaging portion that engages with the formed engaging portion. Then, the movable shaft is horizontally moved in the guide elongated hole through the connecting member according to the ascending / descending movement, and the spring pressure in the downward direction is obtained from the spring member at the lowered position, and the upward / outward direction from the spring member at the raised position. The structure that obtains the spring pressure is adopted.

"Operation" Therefore, in the present invention, when each member except the guide member of the mounting bracket is assembled in advance, and the bracket bases of at least two mounting brackets are fixed to the facing parts of the mounted body, The spring pressure of the spring member presses the movable shaft supported by each metal fitting base in a predetermined direction, and urges each lock member to hang down via the connecting member.

Therefore, if the upper ends of the mounting parts are inserted between the opposing locking members, the locking parts of the respective locking members are automatically locked to the engaging parts of the mounting parts. When the lock member is forcibly pushed upward, the lock member accordingly rises while moving the movable shaft against the spring pressure of the spring member, while the rise of the lock member causes the coupling member to gradually rise upward. When it is rotated and further rotated beyond the horizontal point, at this time, the upper portion of the lock member is pressed upward and outward while the movable shaft is moved in a predetermined direction by the spring pressure of the spring member.

Then, when the attachment part is completely pushed up, the movable shaft is again pressed in the predetermined direction by the spring pressure of the spring member, and the spring pressure is transmitted to the lock member via the connecting member. Since this transmission spring pressure acts as a force for urging the upper side of the lock member upward and outward, each lock member is tilted by the action of the guide member, and its locking portion engages with the attachment part. The joint portion is locked with a strong elastic force.

Therefore, in the final state using the lever principle, the mounting part is elastically mounted on the mounted body, so that the mounted body and the mounting part may have dimensional variations, or Even if there is a difference in the coefficient of thermal expansion between the component and the body to be attached, these are effectively absorbed, and the attachment component is always reliably and firmly attached to the body to be attached.

On the contrary, when removing the mounting parts, each locking member can be forcibly lowered by pulling out the mounting parts from the mounted body against the biasing force of the spring member toward the outer side. After the lock member descends, if the locking of the locking portion with respect to the engaging portion is released, the mounting component can be easily removed from the mounted body.

[Example] Hereinafter, the present invention will be described in detail based on an example illustrated in the drawings.

This embodiment shows an example in which a glass globe is attached to a fixed frame of a ceiling-fixed type lighting fixture, and the lighting fixture in the embodiment also has a light source unit, as shown in FIG.
The fixed frame 11 has a rectangular fixed frame 11 and a rectangular glass globe 14 attached to the fixed frame 11.
11 is a box-shaped outer frame 11A fixed to the ceiling via screws
And a box-shaped inner frame 11B that holds the light bulb 12 and is fixed to the outer frame 11A.
The glass globe 14 has a shape in which the diameter of the upper end portion of the glass globe 14 is reduced, and the engaging concave portion 15 continuous to the outside of the upper end edge is integrally formed.

Further, as shown in FIG. 2, the mounting bracket 20 of this embodiment for mounting the globe 14 on the fixed frame 11 has the above-mentioned fixed frame.
The metal fitting base 21 fixed to the inner frame 11B of 11 and the metal fitting base 21
A movable shaft 22 movably supported on the movable shaft 22, a leaf spring member 23 for urging the movable shaft 22 in a predetermined direction, and a connecting member 24 for the movable shaft 22.
It includes a lock member 25 that is vertically movable via a guide member 26 and a guide member 26 that guides the vertical movement of the lock member 25.

Explaining this concretely, the metal fitting base 21 has a box-like body with one end face having an opening 21a as shown in the drawing, and via a flange portion 27 and a screw formed on both lower end edges thereof,
It is configured to be fixed in the inner frame 11B of the fixed frame 11, and guide long holes 28 of a predetermined size are formed in both side walls of the fixed frame 11, and both ends of the movable shaft 22 are formed in the respective guide long holes 28. The plate spring member 23, which is movably supported to the left and right, and which is provided with a curved elastic shape inside the box-shaped body.
The tip end pressing portion 23a is configured to constantly press and urge the movable shaft 22 in the elongated guide hole 28 toward the opening 21a.

Further, the lock member 25 is a vertically long plate-like body having a predetermined length dimension, and the lower end of the lock member 25 is bent inward to form the glove.
A semi-circular locking portion 29 that locks in the engaging recess 15 of 14 is integrally formed, and a pair of bracket portions 30 is provided on the inner upper portion, and the pair of bracket portions 30 is provided with a pivot 31 through the pivot 31. The lower end portion 24a of the bifurcated connecting member 24 is rotatably pivotally attached.

Then, in the present embodiment, the upper end portion of the connecting member 24.
24b is rotatably attached to both ends of the movable shaft 22 supported in the elongated guide hole 28, and the lock member 25 can be moved up and down with respect to the movable shaft 22 through the connecting member 24. While being connected, the movable shaft 22 can be moved left and right in the guide elongated hole 28 in accordance with the vertical movement of the lock member 25.

Further, the guide member 26 that guides the vertical movement of the lock member 25 is
The guide member 26 is fixed to the inner frame 11B side of the fixed frame 11 in advance by welding or the like, and when the inner frame 11B is fixed to the outer frame 11A.
Is located inside the lower portion of the outer frame 11A, but is not limited to this, the guide member 26 is directly provided on the inner surface of the outer frame 11A, or a convex portion on the inner surface of the outer frame 11A. It is optional depending on the implementation that the projection is integrally formed and the projection is also used as the guide member 26.

Therefore, when the glass globe 14 is attached to the fixed frame 11 of the ceiling-fixed type lighting fixture by using the mounting bracket 20 having such a configuration, first, each member of the mounting bracket 20 except the guide member 26 is previously prepared. After the assembly, the lock member 25 is projected from the cutout window 13 defined on the opposite side portions of the inner frame 11B, and the two metal fitting bases 21 are provided on the opposite side portions of the inner frame 11B.
Are fixed via the flange portion 27 and screws 32, respectively, and then the inner frame 11B is fixed to the outer frame 11A fixed to the ceiling 16 side via bolts and nuts (not shown).

Incidentally, in such a state, as shown in FIG.
Since the movable shaft 22 is pressed in the guide elongated hole 28 of the metal fitting base 21 in the direction of the opening 21a by the spring pressure of the leaf spring member 23 arranged inside the lock member 25, each lock member 25 applies this spring pressure to the connecting member. It is received via 24, and is elastically biased from the notch window 13 of the inner frame 11B to the drooping state by the action of the guide member 26.

Therefore, if the upper end portion of the glass globe 14 is inserted between the lock members 25 that hang down facing each other, the globe 14
The upper edge of the lock member 25 is inserted while expanding the locking portion 29 of each locking member 25 and passes between the locking portions 29, and at the same time, the locking portion 29 of each locking member 25 is engaged with the engaging recess of the globe 14. It automatically locks in 15 so that the glove 14 once holds the fixed frame.
It is temporarily fixed to 11.

Next, when the globe 14 in the temporarily fixed state is forcibly pushed upward, as shown in FIG. 4, each locking member 25 is pressed by the pressing action of the bottom surface of the engagement recess 15 against the locking portion 29.
However, while the movable shaft 22 is moved in the opposite direction in the guide elongated hole 28 against the spring pressure of the leaf spring member 23, the guide member 26 guides the guide member 26 to move up synchronously.

Further, when the lock members 25 are synchronously raised, the lower end portion 24a side of the connecting member 24 is gradually turned upward accordingly, but the connecting members 24 are further turned beyond the horizontal point. Then,
This time, the spring pressure of the leaf spring member 23 moves the movable shaft 22 in the guide elongated hole 28 toward the opening 21a, while transmitting the spring pressure to the upper side of the lock member 25.

Then, when the globe 14 is completely pushed up, as shown in FIG. 5, the movable shaft 22 is again pushed in the guide elongated hole 28 toward the opening 21a by the spring pressure of the leaf spring member 23, and the spring pressure is increased. Although transmitted to the lock member 25 via the connecting member 24, in such a state, this transmission spring pressure serves as a pressing force for urging the upper side of the lock member 25 upward and outward. Each lock member 25 is tilted by the action of the guide member 26, and locks its own locking portion 29 in the engaging recess 15 of the globe 14 with a strong elastic force.

Therefore, in this embodiment, since the globe 14 is elastically attached to the fixed frame 11 in the final locked state using the lever principle, the fixed frame 11 is used.
Even if there is a dimensional variation in the globe 14 and the like, it is possible to effectively absorb the variation and the like of the both and to always attach the glass globe 14 securely and firmly,
There is no need to worry about the fall of the globe 14 as in the conventional case, and the difference in thermal expansion between the metal fixing frame 11 and the glass globe 14 can be effectively absorbed, and the globe 14 can be always supported in a stable state. Become.

On the contrary, when the globe 14 is removed from the fixed frame 14, if the globe 14 is pulled out from the fixed frame 11 against the pressing force applied to the outer side of the leaf spring member 23, the operation is completely opposite to the above. Since each locking member 25 can be forcibly lowered, after the lowering of each locking member 25, only by releasing the locking of the locking portion 29 of the locking member 25 with respect to the engaging recess 15, the globe 14 itself. Can be easily removed from the fixed frame 11.

Therefore, when using the mounting bracket 20 according to the present embodiment, simply by vertically moving the globe 14 up and down,
Since the one-touch attachment / detachment of the globe 14 can be quickly performed, the workability is extremely good in any case.

Further, as described above, it is possible to surely prevent the globe 14 from dropping by the pressing force applied to the outer side of the leaf spring member 23 using the lever principle, but in the case of expecting double safety, For example, as shown in FIGS. 6A and 6B, the locking members facing each other when the globe 14 is temporarily fixed as described above.
A lock bar that has a U shape inside and outside the locking portion 29 of the 25
With the configuration in which 32 is attached, even if an unexpected external force is applied due to an earthquake or the like and each locking member 25 is accidentally lowered, the locking action of the lock bar 32 causes the opposing locking portions 29 of the glove 14 to move. This will prevent the globe 14 from falling further, as the weight will completely prevent it from expanding outwards.

In the above embodiment, the square glass globe 14 is attached to the square metal fixed frame 11, but the shapes of the fixed frame 11 and the globe 14 are limited to square. Needless to say, the present invention can be applied to the fixed frame 11 and the globe 14 having a round shape or any other shape, and the molding material and structure of the fixed frame 11 and the globe 14 themselves are not limited to those of the embodiment. Not something.

Further, in the above-described embodiment, the fixed frame 11 of the lighting fixture is the mounted body and the glass globe 14 is the mounting part, but the present invention is not limited to this, and other As long as it is necessary to detachably attach various components to the attached body, it goes without saying that other components can be easily implemented and applied without departing from the spirit of the present invention.

"Effects of the Invention" As described above, according to the mounting bracket of the present invention, even if there are variations in dimensions or differences in the coefficient of thermal expansion, these are effectively absorbed and the mounting parts are mounted. Since it can be securely and firmly attached to the body, the attachment state of the attachment component becomes unstable as in the conventional case, and there is no fear that the attachment component will easily drop from the attached body.

Moreover, when attaching and detaching work, it is possible to attach the attachment parts to the attached object with one touch with a very simple work of linearly moving the attachment parts without performing complicated screwing work as in the past. Or, since it can be removed with one touch, a great improvement in workability can be expected.

Further, the mounting metal fitting of the present invention is not restricted by the structure, use, size, shape, material, etc. of the mounting parts, the body to be mounted, etc., so that the range of use is of course wide. Especially, when it is used for a lighting fixture, various gloves can always be securely and firmly attached to the fixed frame, so that the optimal attachment state of the gloves can be guaranteed.

Further, even when compared with the conventional dedicated mounting bracket, under the mounting bracket of the present invention, it is possible to eliminate the fear of damaging the gloves when mounting the glass gloves.
