Description

Attachment mechanism for long objects

Technical field

The present invention relates to a mechanism for attaching a long object such as a straight tube fluorescent lamp.

Background art

[0002] Straight-tube fluorescent lamps are usually used by being attached to a fluorescent lamp lighting device installed in an installation section. The fluorescent lamp lighting device is a device for supporting the fluorescent lamp on the installation portion and supplying power to the fluorescent lamp via a lighting circuit. However, in the conventional straight tube type fluorescent lamp, it is necessary to attach the cap pins protruding as the cap terminals at both ends to the sockets at both ends of the fluorescent lamp lighting device, and this mounting work is not always easy. Then I helped.

[0003] Therefore, in Japanese Patent Application Japanese Patent Application No. 2005-39257, the applicant of the present invention protruded downward from the attachment portions 3, 3 at both ends of the fluorescent tube 2 in the fluorescent lamp 1, as shown in FIG. The protruding plate 3a 'is inserted into the fitting holes 7a' of the mounting lamps 7 and 7 provided at both ends of the fluorescent lamp lighting device 6, and is simply locked to the locking part 7b. We proposed an invention that can be installed in.

[0004] The fluorescent lamp 1 has a fluorescent tube mounting portion 3, 3 disposed at both ends of a fluorescent tube 2 elongated in the left-right direction, and each mounting portion 3 is lined up in the front-rear direction. A pair of projecting plates 3a, 3a projecting downward is provided. A claw portion 3b that protrudes outward is provided at the lower end portion of each protruding plate 3a, which is opposite to the other protruding plate 3a in parallel in the front-rear direction.

[0005] Each protruding plate 3a is a resin plate that is thin in the front-rear direction and has a certain length in the left-right direction, and its upper end is connected to the main body by integral molding at a relatively upper portion of the attachment portion 3, and the attachment portion 3 Therefore, if the pair of projecting plates 3a, 3a are pressed with both side forces in the front-rear direction, the claw portions 3b, 3b are provided by the elasticity of the grease. The lower end is now inward (in the direction of approaching each other)! /

[0006] Each claw portion 3b extends outside the lower end of the protruding plate 3a over the entire length in the left-right direction of the protruding plate 3a. Side force Projected. Further, each of the claw portions 3b is formed with a fitting gradient so that the length of the protrusion in the front-rear direction gradually increases and becomes maximum at the upper end.

[0007] The fluorescent lamp lighting device 6 includes a lighting circuit for the fluorescent tube 2 inside, and the mounting portions 3 and 3 of the fluorescent lamp 1 are locked on the upper surfaces of both ends of a resin case covering the lighting circuit. Mounting receiving parts 7 and 7 are provided. Each attachment receiving portion 7 is provided with a pair of insertion holes 7a, 7a arranged in the front-rear direction. Each insertion hole 7a has a claw that opens on the upper surface of the case of the mounting receiving portion 7 and has a length in the front-rear direction that is sufficiently longer than the protrusion plate 3a. It is a slit-shaped opening that is sufficiently wider than the length of the maximum protrusion length of part 3b

[0008] Further, as shown in the partial sectional view, a rectangular sleeve that slightly protrudes downward is formed on the case inner side of each fitting hole 7a so as to guide the edge of the opening hole downward. In this sleeve, an end edge portion (outside) opposite to the other fitting hole 7a protrudes inward to form a locking portion 7b. In other words, the distance between the pair of fitting holes 7a is actually shorter than the distance between the pair of protruding plates 3a, but as a result, the pair of protruding plates 3a are paired with the pair of protruding plates 3a. When trying to insert into the insertion holes 7a, the claw portions 3b protruding outside the protruding plates 3a collide with the outer edge portions of the insertion holes 7a. It is said that the outer edge portion of the projection protrudes more inward than the original, and this protruding portion is the locking portion 7b.

[0009] In the fluorescent lamp 1, the projections 3a 'of the mounting portions 3, 3 at both ends are inserted into the mounting receiving portions 7, 7' of the both ends of the fluorescent lamp lighting device 6. As a result, the claw portion 3b of each protruding plate 3a is locked to the locking portion 7b of each fitting hole 7a, so that it is attached to the fluorescent lamp lighting device 6 as shown in FIG. . In other words, as shown by the arrows in FIG. 9, the fluorescent lamp 1 is lowered from directly above the fluorescent lamp lighting device 6, and each pair of protruding plates 3a, 3a is inserted into the respective fitting holes 7a, 7a. Then, the claw portion 3b of each protruding plate 3a collides with the locking portion 7b of each fitting hole 7a. However, each claw portion 3b is formed with a fitting gradient in which the protruding length gradually increases from the lower end, so that this fitting gradient abuts against the upper edge of the locking portion 7b. Thus, the claw portion 3b is pushed inward.

[0010] Then, when the fluorescent lamp 1 is pushed further downward in this state, the lower end of the protruding plate 3a is moved inward. While rubbing, it enters the fitting hole 7a together with the claw part 3b. When the claw part 3b reaches below the lower end of the locking part 7b, the stagnation of the lower end of the protruding plate 3a returns straight due to the elasticity of the grease, and this claw part 3b is engaged with the lower end of the locking part 7b. It is stopped so that it cannot return upward. Accordingly, the fluorescent lamp 1 can be securely attached because the attachment parts 3 and 3 at both ends are not detached from the attachment receiving parts 7 and 7 of the fluorescent lamp lighting device 6.

In addition, the fluorescent lamp 1 has a pair of terminals 4 and 4 projecting from the lower surface of each mounting portion 3, and these terminals are also provided on the upper surface of the case of each mounting receiving portion 7 of the fluorescent lamp lighting device 6. Terminal holes 7c and 7c for inserting 4 and 4 are formed. Each terminal 4 is a conductive metal plate connected to a lead wire (not shown) drawn from both end faces of the fluorescent tube 2, and projects from the bottom surface of each mounting portion 3 in a pair of plug blade shapes of the power plug. ing.

[0012] The terminal holes 7c, 7c are a pair of socket-shaped opening holes provided on the upper surface of the case of each mounting receiving portion 7, and a terminal receiver (not shown) is provided inside the case below each terminal hole 7c. Brackets are arranged. Then, when each protruding plate 3a is inserted into the fitting hole 7a to attach the fluorescent lamp 1, each of these terminals 4 also enters the terminal hole 7c at the same time, and is connected to the terminal bracket inside the case. . Therefore, the fluorescent lamp lighting device 6 can supply power to the fluorescent lamp 1 from the lighting circuit via these terminal fittings.

[0013] Note that the fluorescent lamp 1 is not provided with a conventional base at both ends of the fluorescent tube 2, and there is no force, and the base pin does not protrude in the left-right direction from these bases. In addition, when a plurality of lamps are arranged adjacent to each other in the left-right direction on the wall or the like, there is an advantage that almost no non-light emitting area is generated between the respective fluorescent lamps 1 arranged on the left and right, and the lighting effect can be enhanced. .

[0014] When removing the fluorescent lamp 1 from the fluorescent lamp lighting device 6, place both hands on the mounting portions 3 and 3 on both ends of the fluorescent lamp 1 and attach the protruding plates 3a and 3a of each mounting portion 3 from both sides. By pushing so as to be pinched with a finger, the lower end portions of these projecting plates 3a, 3a are folded inward to release the locking of the claw portions 3b, 3b to the locking portions 7b, 7b. If the mounting portions 3 and 3 at both ends are simultaneously lifted upward, the protruding plates 3a and 3a are pulled out from the fitting holes 7a and 7a together with the claw portions 3b and 3b, and the fluorescent lamp 1 is connected to the fluorescent lamp lighting device 6 Can be removed from.

[0015] However, the fluorescent lamp 1 is particularly used for wide room lighting, for example, installed on the ceiling. In such a case, the left and right lengths may be extremely long, and even if both hands are spread out, the hands 3 and 3 at both ends of the fluorescent lamp 1 may not reach. Even if the fluorescent lamp 1 is not so long, for example, to remove the fluorescent lamp 1 on the ceiling, support yourself with one hand on the stepladder, or cover the fluorescent lamp 1 and hold the shade with one hand. In some cases, you need to support, and you cannot use both hands at the same time. For this reason, if only one mounting part 3 is unlocked with one hand and the fluorescent lamp 1 is to be removed, the other mounting part 3 is unlocked. Otherwise, excessive force may be applied to the fluorescent tube 2 and it may be damaged.

[0016] In the case of the fluorescent lamp 1 installed on the ceiling, the vertical direction is opposite to that shown in the figure, so that the fluorescent lamp 1 can be obtained simply by releasing the locking of one mounting portion 3 with one hand. Due to its own weight, one side is lowered and slanted, and simply releasing the fluorescent lamp 1 may cause damage. Therefore, if the fluorescent lamp 1 is long or installed, it may not be possible for one person to remove it from the fluorescent lamp lighting device 6, and inconvenience may occur when replacing the fluorescent lamp 1. Has occurred!

[0017] It should be noted that a similar problem may occur when the fluorescent lamp 1 is attached to the fluorescent lamp lighting device 6, but in practice, if the claw portion 3b has a fitting gradient, only one hand is used, One mounting part 3 and the other mounting part 3 can be locked in order, or both mounting parts 3 and 3 can be locked simultaneously.

Disclosure of the invention

Problems to be solved by the invention

[0018] According to the present invention, by forming a removal gradient in the claw portion that locks the attachment portions at both ends of the long object, the engagement of the other attachment portion can be achieved only by releasing the engagement of one attachment portion. It is intended to provide a mechanism for attaching long objects that can be automatically disengaged.

Means for solving the problem

[0019] The invention of claim 1 is directed to a long object to be attached by locking attachment portions provided at both ends of a long object that is long to the left and right to left and right attachment receiving parts of a lower installation part, respectively. In the mounting mechanism, each mounting portion is provided with a protruding portion that protrudes downward, and the front and rear outer portions of the lower end portion of the protruding portion have a predetermined length along the left-right direction. Pulling out in the direction opposite to the protruding direction due to the force and elasticity of the claw that forms the detachment gradient, the protruding length of the part facing the other mounting part decreases toward the other mounting part side. Each mounting receiving portion is formed with a fitting portion that fits the protruding portion of the mounting portion, and the edge portions on both outer sides in the front-rear direction of the fitting portion are predetermined along the left-right direction. It is characterized in that a locking portion is provided that protrudes toward the inside facing each other over a length longer than the length.

[0020] In the invention of claim 2, each of the attachment portions is provided with a pair of protrusions that protrude downward in a line in the front-rear direction, and the claw portions are provided at the lower ends of the protrusions that form the pair. Provided on the outer side opposite to the other projecting portion, each mounting receiving portion is formed with a pair of fitting portions into which a pair of projecting portions are fitted, and the locking portion is a pair of the engaging portions. It is characterized in that each of the fitting parts is projected at an end edge opposite to the other fitting part.

[0021] In the invention of claim 3, each claw portion has a predetermined length along the left-right direction on the inner portion facing / matching with the other protrusion at the lower end of each pair of protrusions. The protrusion direction is defined by the force and elasticity of the claw part that protrudes inward and forms a gradient for removal in which the protrusion length of the part facing the other attachment part decreases toward the other attachment part side. It is provided so as to be retractable in the opposite direction, and each of the fitting portions has a hole shape having an end edge on the opposite side to the other fitting portion to be paired, or on the opposite side to the other fitting portion. It has a guide groove shape that does not have an end edge portion, and is characterized in that it protrudes from the end edge portion on the side facing the other insertion portion in each of the insertion portions that form the respective locking portion force pairs. .

[0022] According to the invention of claim 4, the detachment gradient is not formed in each of the claw portions, and the protruding length of the portion on the side facing the other mounting receiving portion of each locking portion is the other mounting receiving portion. It is characterized in that a slope for removal that decreases toward the part side is formed.

[0023] The invention of claim 5 is that each of the claw portions is fixed without being retractable, and each of the locking portions is provided so as to be retractable in the direction opposite to the protruding direction by elasticity. It is a feature.

[0024] The invention of claim 6 is characterized in that a temporary fixing projection that slightly protrudes is provided at the upper end portion of the locking portion that protrudes from the end edge of each of the fitting portions.

[0025] It should be noted that the front-rear, left-right, and up-down directions in the present application are particularly those that indicate actual directions. Others are merely for convenience in showing directions orthogonal to each other in three dimensions. For example, when installing a long object on the ceiling, the vertical direction is actually reversed. For example, when installing a long object on the wall sideways, the left-right direction is parallel to the wall surface in the actual horizontal direction, the up-down direction is perpendicular to the wall surface in the actual horizontal direction, and the front-back direction is Actual vertical direction. Furthermore, for example, when a long object is installed vertically on a wall surface, the front-rear direction is a direction parallel to the wall surface in the actual horizontal direction, and the up-down direction is a direction orthogonal to the wall surface in the actual horizontal direction. The direction is the actual vertical direction.

[0026] According to the invention of claim 1, the protrusions of the attachment portions at both ends of the long object are fitted into the fitting portions of the attachment receiving portions of the installation portion, and the claw portions of the protrusions are engaged with the fitting portions. This long object can be attached to the installation part by engaging with the stop part. Then, the hook of the protruding portion of either one of the mounting portions is elastically pulled in to release the locking to the locking portion, and when one of the mounting portions is pulled upward, the entire long object is Since one end portion is inclined upward, one side of the claw portion of the protruding portion of the attachment portion of the other end portion is lifted upward, and the removal gradient comes into contact with the locking portion. Then, since the protrusion length of this removal gradient decreases toward one side, the claw portion can be elastically pulled in by being brought into contact with the locking portion and lifted from this one side. Therefore, the latching of the protruding portion of the other mounting portion to the locking portion of the entire claw portion can be released. Therefore, the lock is released by pulling the claw of the protruding part only at one of the attachments, and the other attachment is automatically released simply by lifting this one attachment. As a result, it is possible to easily remove a long object with one hand.

[0027] Note that it is not necessary to release the locking of the attachment part of the long object! / V, try to lift only the attachment part of the deviation, or lift both attachment parts straight upward at the same time Even so, since the portions other than the removal gradient in the claw portions of the left and right mounting portions are securely locked to the locking portions, there is no possibility that the attachment of the long object will be uncertain! / ヽ

[0028] According to the invention of claim 2, since a pair of protrusions arranged in the front-rear direction is provided in each mounting part, if these protrusions are made of an elastic body such as a grease, the pair of protrusions is provided. Sudden By pushing the protruding part so as to sandwich the force on both sides, the claw part protruding outward in the front-rear direction can be pulled inward by elasticity, and a structure that can be pulled in can be easily configured. become able to. In addition, since a pair of fitting portions are formed in each mounting receiving portion, the positional relationship between the projecting portion and the fitting portion into which the protruding portion is fitted is clarified, and the attachment work of the long object can be easily divided. Can do.

[0029] It should be noted that the protrusion is preferably configured as a thin plate-like protruding plate in the front-rear direction so that appropriate elasticity in the front-rear direction is generated, and the fitting portion is also an opening hole into which the protruding plate is inserted. It is preferable to configure it as a shaped fitting hole.

[0030] According to the invention of claim 3, since each attachment portion is provided with a pair of protrusions arranged in the front-rear direction, if the protrusions are made of an elastic body such as grease, the pair of protrusions is provided. By pushing the protruding part to both sides, the claw part protruding inward in the front-rear direction can be inserted into the bow I by inertia, and this claw part can be inserted into the bow I Can be configured easily. Also, if each fitting portion has a guide groove shape that does not have an edge portion on the side opposite to the other fitting portion, it is not necessary to make these fitting portions into an opening hole shape. Since it can be formed on both outer side surfaces in the front-rear direction of the portion, the structure of the attachment receiving portion can also be simplified.

[0031] According to the invention of claim 4, since the detachment gradient is formed on the locking portion side, as in the case where the detachment gradient is formed on the claw portion, only one of the attachment portions is used. The operation of pulling the claw part of the protruding part is performed to release the locking, and the locking of the other mounting part can be automatically released simply by lifting this one mounting part.

[0032] According to the invention of claim 5, since the locking portion is provided so as to be retractable, similarly to the case where the claw portion can be retracted, the fitting portion is provided only in one of the attachment receiving portions. It is possible to automatically release the locking of the other mounting portion by simply releasing the locking portion by releasing the locking portion and lifting the one mounting portion.

[0033] According to the invention of claim 6, since the claw portion is temporarily locked to the temporary locking projection before the original locking is performed by the locking portion, the claw portion is attached to the locking portion. Even when left without being securely locked, it is possible to prevent the long object from being inadvertently detached. In particular, when installing a long object on the ceiling, if this locking is not performed securely, the long object Can be prevented from falling.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best embodiment of the present invention will be described with reference to FIGS. In these drawings, the same reference numerals are given to constituent members having functions similar to those of the conventional example shown in FIGS. 9 and 10.

In this embodiment, as in the conventional example shown in FIGS. 9 and 10, a mounting mechanism for attaching a straight fluorescent lamp 1 that is long on the left and right to a fluorescent lamp lighting device 6 installed in an installation section. explain about. The configuration of the fluorescent lamp lighting device 6 is exactly the same as this conventional example. Also, the fluorescent lamp 1 has a fluorescent mounting portion 3, 3 disposed at both ends of a fluorescent tube 2 that is long in the left-right direction, and a pair of projecting plates 3a, 3a are provided on each mounting portion 3. The configuration in which the claw portions 3b and 3b projecting outward are provided at the lower end portions of the projecting plates 3a and 3a is the same as that of the conventional example. Each of the mounting portions 3 is the same as the conventional example in that the pair of terminals 4 and 4 protrude from the lower surface.

[0038] In this embodiment, as shown in FIG. 1 and FIG. 2, in this embodiment, the pair of protruding plates 3a, 3a of each attachment portion 3 faces the other attachment portion 3 in the claw portions 3b, 3b. The configuration in which the removal gradients 3c and 3c are provided on the side is different from the conventional example. That is, the claw portion 3b of the conventional example shown in FIG. 9 is provided so as to protrude over the entire length in the left-right direction of the outer surface force on the opposite side to the other protruding portion at the lower end of the protruding plate 3a. In addition, the projecting length from the outer side over the entire length in the left-right direction is almost zero at the lower end. The projecting length gradually increases as the force is applied upward, and the maximum is at the upper end of the claw part 3b. A gradient is formed.

[0039] In addition to this, the claw portion 3b of the present embodiment has a side facing the other mounting portion 3 (see Figs. 1 and 2). In the case of the attachment portion 3 at the left end shown in the drawing, a protruding gradient force of approximately half of the right side) is provided with a removal gradient 3c that decreases toward the other attachment portion 3 side. Therefore, the locking with the locking portion 7b by the claw portion 3b is performed in the same manner as in the conventional example on the side opposite to the other mounting portion 3, so that the force that ensures a reliable locking as a whole can be obtained. In the portion where the external gradient 3c is provided, the closer to the other mounting portion 3 side, the more locally the locking becomes uncertain.

A procedure for attaching the fluorescent lamp 1 having the above configuration to the fluorescent lamp lighting device 6 will be described. As shown in FIG. 3, each mounting portion 3 of the fluorescent lamp 1 is arranged directly above each mounting receiving portion 7 of the fluorescent lamp lighting device 6. When this fluorescent lamp 1 is lowered as it is, the terminals 4 and 4 enter the terminal holes 7c and 7c of the mounting receiving portion 7 which do not appear in FIG. 3, and the protruding plates 3a and 3a also enter the fitting holes 7a and 7a. I will try. However, since the engaging portions 7b and 7b protrude inward from the outer edge portions of these fitting holes 7a and 7a, the claw portions 3b and 3b of the protruding plates 3a and 3a are formed. The slope of the fitting gradient whose protrusion length increases toward the upper side collides with the upper edge of the locking portions 7b and 7b.

[0041] Therefore, when the fluorescent lamp 1 is pushed further downward, the upper edges of the locking portions 7b, 7b push the fitting gradient of the claw portions 3b, 3b inward, and the lower ends of the projecting plates 3a, 3a are inside The claw portions 3b and 3b are also pulled inwardly opposite to the protruding direction, so that the protruding plates 3a and 3a are inserted into the fitting holes 7a and 7a together with the claw portions 3b and 3b as shown in FIG. Get in automatically.

[0042] When the fluorescent lamp 1 is further pushed downward, the protruding ends of the claw portions 3b, 3b descend while sliding on the protruding end surfaces of the locking portions 7b, 7b and pass the lower ends of the locking portions 7b, 7b. . Then, as shown in FIG. 5, the elasticity of the protruding plates 3a, 3a returns to straight again due to elasticity, and the claw portions 3b, 3b also return to the outer protruding state, so that the locking portions 7b protruding inward , 7b and locking is performed, so that the fluorescent lamp 1 cannot return upward again.

[0043] When the projecting plates 3a, 3a and the claw portions 3b, 3b enter the fitting holes 7a, 7a, the terminals 4, 4 that have previously entered the terminal holes 7c, 7c become the terminal receiving brackets 5, 5 When the claw portions 3b, 3b are locked to the locking portions 7b, 7b as shown in FIG. 5, these terminals 4, 4 are securely connected to the terminal brackets 5, 5. Become so. Therefore, when the fluorescent lamp 1 is attached to the fluorescent lamp lighting device 6 by the locking of the claw portion 3b and the locking portion 7b, the lighting circuit in the fluorescent lamp lighting device 6 connects the terminal 4 from the terminal bracket 5. Power to the fluorescent tube 2 You can turn it on.

[0044] First, the procedure for removing the fluorescent lamp lighting device 6 using the both hands as in the prior art will be described. By attaching both hands to the mounting parts 3 and 3 on both ends of the fluorescent lamp 1 shown in Fig. 5 and pressing the protruding plates 3a and 3a of each mounting part 3 with both side fingers, these protruding plates 3a , The lower end of 3a is folded inward and the claws 3b and 3b are pulled in the direction opposite to the protruding direction. Then, the locking of the claw portions 3b, 3b to the locking portions 7b, 7b is released. Therefore, if both the mounting portions 3 are simultaneously lifted upward, the projecting plates 3a, 3a are removed from the fitting holes 7a, 7a. The fluorescent lamp 1 can be removed from the fluorescent lamp lighting device 6.

Next, a procedure for removing the fluorescent lamp 1 having the above configuration from the fluorescent lamp lighting device 6 using only one hand will be described. By attaching one hand to the mounting part 3 at one end of the fluorescent lamp 1 shown in Fig. 5 and pressing the protruding plates 3a, 3a of this mounting part 3 so that both side forces are sandwiched between fingers, these protruding plates 3a, Hold the lower end of 3a inward and pull the claws 3b, 3b in the direction opposite to the protruding direction. Then, the locking of the claw portions 3b, 3b to the locking portions 7b, 7b is released. Therefore, as shown in FIG. 6, the mounting portion 3 at one end (right side in FIG. 6) is pulled upward. Then, the protruding plates 3a, 3a can be pulled out from the fitting holes 7a, 7a.

[0046] However, in the prior art, when the fluorescent lamp 1 is lifted by releasing only the locking of the one mounting portion 3 in this way, the claw portion 3b in which the locking of the other mounting portion 3 is not released. The glass tube may break or break due to a strong bending stress applied to the fluorescent tube 2. However, in the fluorescent lamp 1 of the present embodiment, the removal gradients 3c and 3c are formed on the claw portions 3b and 3b of the mounting portions 3, so that the mounting portions 3 cannot be lifted straight upward. However, by lifting only one mounting part 3 in this way and holding the force in the rotational direction indicated by the arrow in FIG. 6 on the claw parts 3b, 3b of the other mounting part 3, the removal gradient 3c, The side force of 3c can also automatically unlock the claw portions 3b, 3b.

That is, when a force in the rotational direction is applied to the fluorescent lamp 1, the side facing the one mounting portion 3 in the removal gradients 3c, 3c formed on the claw portions 3b, 3b of the other mounting portion 3 (see FIG. In Fig. 6, the right end) also presses the lower edge of the locking part 7b, 7b against the lower edge. The one end of these removal gradients 3c, 3c is the portion with the smallest protrusion length and the most uncertain locking to the locking portions 7b, 7b. Will come off. [0048] Since these removal gradients 3c, 3c have a gradient in which the protruding length increases toward the other side (left side in FIG. 6), by adding a force in the rotation direction to the fluorescent lamp 1, The one end that has already been unlocked is pushed by the lower edge of the locking portions 7b and 7b, so that the protruding plates 3a and 3a are held inward. Then, the claw portions 3b and 3b are pulled inwardly opposite to the protruding direction, so that the locking with the locking portions 7b and 7b at the removal gradients 3c and 3c is shifted from one end to the other side. Finally, as shown in FIG. 6, the locking of the claw portions 3b and 3b where the removal gradients 3c and 3c are not formed is released as shown in FIG.

[0049] Therefore, after the locking of the claw portions 3b, 3b of the other mounting portion 3 is completely released, the protruding plates 3a, 3a can be inserted into the insertion holes 7a, 7a even if they are lifted straight up. The fluorescent lamp 1 can be detached from the fluorescent lamp lighting device 6 with one hand only.

[0050] Further, since the fluorescent lamp 1 can be detached from the other attachment portion 3 by the same procedure as described above, it is confirmed whether the right or left side attachment portion 3 should be removed before the detaching operation. There is no need to approve.

[0051] As described above, according to the present embodiment, the locking of the claw portions 3b, 3b of one of the attachment portions 3 of the fluorescent lamp 1 is released by operation, and this one attachment portion 3 is removed. By simply lifting, the hooks 3b, 3b of the other mounting part 3 can be automatically released by the removal gradients 3c, 3c, so remove the fluorescent lamp 1 using only one hand. You will be able to

[0052] Even when both hands can be used, the other fluorescent lamp 1 can be safely removed by supporting the whole fluorescent lamp 1 with the other hand. Therefore, for example, even when a very long fluorescent lamp 1 is installed on the ceiling or the like, the replacement work can be easily performed by one person, and convenience can be improved.

In the above-described embodiment, the projection length at the lower end of the fitting gradient of the claw portion 3b is almost zero, and the force shown in this case shows that the claw portion 3b protrudes to some extent even at this lower end. It's okay. However, when the pair of claw portions 3b, 3b are lowered to attach the fluorescent lamp 1, the upper edges of the pair of locking portions 7b, 7b are initially fitted with gradients for fitting these claw portions 3b, 3b. The lower end of the fitting slope is easier to insert if it is in contact with the slope of Then, it is preferable that the protrusion length is as short as possible.

[0054] Further, the protruding plate 3a has a lower end protruding slightly further downward than the claw portion 3b, and on the outer side surface of the protruding portion, the plate continues downward from the fitting gradient of the claw portion 3b. By forming a gradient that reduces the thickness, the lower end may have a wedge shape. Thus, if the protruding plate 3a has a sharp wedge shape at the lower end, the insertion work into the fitting hole 7a when the fluorescent lamp 1 is attached becomes easier.

[0055] Further, the fitting gradient of the claw portion 3b is not limited to the inclined one plane shape as in the above embodiment, but may be a plurality of planes or curved surfaces that may be formed by continuous curved surfaces. Even though they are formed by discontinuous connection.

[0056] Further, the fitting gradient may not be formed in the claw portion 3b, and the protruding lengths in the vertical direction may be equal. The protruding shape of the claw portion 3b is not necessarily limited to a specific one. As described above, when the fitting gradient is not formed on the claw portion 3b, the fitting gradient may be formed on both sides of the locking portion 7b. However, a fitting gradient is formed in both the claw portion 3b and the locking portion 7b. In this case, when the protruding plate 3a is inserted into the fitting hole 7a in order to attach the fluorescent lamp 1, However, it is necessary to pull in the claw part 3b by the operation.

[0057] In the above embodiment, the case where the removal gradient 3c is formed in almost half of the total length in the left-right direction of the claw portion 3b is shown. As long as it is formed on the side of the fluorescent lamp 1 facing the mounting portion 3 at the end different from the mounting portion 3, the formation area is not limited. However, if the removal gradient 3c is formed in a wide range, there will be too many parts where the claw portion 3b will be unreliably locked, and if it is formed in a narrow range, removal with one hand may not be performed smoothly. Occurs.

[0058] Furthermore, in the above embodiment, the case where the removal gradient 3c is formed as a vertical surface slightly inclined back and forth rather than along the left-right direction has been shown, but the side facing the attachment portion 3 at the other end portion is shown. If the surface is such that the protrusion length decreases, it is not always necessary to have such a vertical surface. Rather, the removal gradient 3c is preferably such that the protrusion length decreases toward the top! / . This is because if the removal gradient 3c is a surface that reduces the upper protrusion length only on the side facing the mounting portion 3 at the other end, the downward force is also pressed against the edge of the lower end of the locking portion 7b. In addition, This is because the portion with the smallest protrusion length comes into contact, and the lock is released more smoothly.

[0059] Further, the removal gradient 3c is not limited to a flat one as in the above embodiment, and a plurality of flat surfaces and curved surfaces that may be formed by continuous curved surfaces are connected discontinuously. It may have been formed by force S.

[0060] In the above embodiment, the force shown in the case of using the plate-like protruding plate 3a is not necessarily one plate as long as the protruding plate 3a is capable of retracting the claw portion 3b by elasticity. It may be one or more rod-like or grid-like protrusions. In this way, if the elasticity of the protruding portion such as the protruding plate 3a is used, a structure in which the claw portion 3b can be retracted can be realized with a simple configuration. Manufacturing is also easy.

[0061] However, the structure that allows each of the claw portions 3b to be retracted is not limited to a structure that uses the elasticity of the protruding portion such as the protruding plate 3a. For example, the claw portion 3b is moved back and forth at the lower end of the protruding plate 3a. The claw portion 3b may be urged to a predetermined position by an elastic body such as a panel while being arranged so as to be slidable back and forth to a predetermined position in the direction. If the elasticity of the protruding plate 3a or the like is not used in this way, it is also possible to provide only one block-like protruding portion for each mounting portion 3 instead of the pair of protruding plates 3a and 3a. Good. In this case, the claw portions 3b, 3b are provided on both outer side portions in the front-rear direction at the lower end portion of one projecting portion such as a block shape.

[0062] In the above embodiment, the case where the nail portions 3b and 3b are unlocked by pressing the pair of protruding plates 3a and 3a so that both side forces are also sandwiched between fingers is shown. The release method is also arbitrary. For example, there is a release mechanism that pulls the claw portions 3b, 3b and releases the lock by pressing a button or lever provided on the attachment portion 3 or the attachment receiving portion 7. Also good. In particular, when the claw portion 3b is urged by an elastic body such as a panel and can be retracted, it is more convenient to use such a release mechanism.

[0063] By the way, if such a button or the like is pushed and released and the lock remains released even when the hand is released, the button or the like of one mounting part 3 is pushed with one hand to release the lock. After that, you can press the button on the other mounting part 3 with the same one hand to release the lock. In the case of the extremely long fluorescent lamp 1 installed in the case, it is necessary to continue to support the fluorescent lamp 1 while moving one hand from one mounting portion 3 to the other mounting portion 3, so as in this embodiment Unlock one mounting part 3 with one hand and lift it as it is (if the fluorescent lamp 1 is installed on the ceiling, pull it down), the other mounting part 3 is automatically unlocked. Such a mechanism is more useful.

[0064] In the above embodiment, in order to make the position when inserting the pair of projecting plates 3a, 3a easy to understand, a pair of fitting holes 7a, 7a are also formed in the attachment receiving portion 7. As shown in the figure, since it is only necessary to have edge portions on both outer sides in order to project the locking portions 7b, 7b, a single fitting hole having a width in the front-rear direction is formed, and a pair of protrusions are formed here. The plates 3a and 3a may be inserted together. For example, when a single block-like projecting portion is provided instead of the pair of projecting plates 3a, 3a, it is necessary to form the fitting hole only in one place.

[0065] Further, instead of the pair of fitting holes 7a, 7a and one fitting hole, a fitting part such as a slit-like groove may be formed in the attachment receiving part 7.

[0066] Further, in the above embodiment, the locking portion 7b protrudes inward with a uniform protruding length over a certain length in the vertical direction, and the claw at the lower end portion of the protruding plate 3a is only at the lower end of the locking portion 7b. As shown in FIG. 7, the upper end portion of the locking portion 7b can be provided with a temporary locking projection 7d that protrudes slightly more than the locking portion 7b. (Claim 6).

[0067] When such a temporary fixing projection 7d is provided on the locking portion 7b, in particular, for example, when the fluorescent lamp 1 is installed on the ceiling, the original locking of the claw portion 3b to the locking portion 7b is performed. Even after the is released, it is possible to prevent the fluorescent lamp 1 from being inadvertently dropped. However, the fluorescent lamp 1 will not illuminate if the terminals 4 ... are connected to the terminal brackets 5 ... It can be used without noticing that this lock is incomplete. However, if such a temporary locking projection 7d is provided on the locking portion 7b, for example, it is assumed that the fluorescent lamp 1 installed on the ceiling is incompletely locked and is gradually lowered due to vibration or the like. However, since the claw portion 3b is temporarily locked to the temporary fixing projection 7d, it is possible to prevent an accident such that the fluorescent lamp 1 suddenly falls during use.

[0068] In the case shown in FIG. 7, in the state where the claw portion 3b is temporarily locked to the locking portion 7b, the end portion Since the connection between the terminal 4 and the terminal bracket 5 is also cut off, the fluorescent lamp 2 is not lit, so that the fluorescent lamp 1 is likely to come off from the fluorescent lamp lighting device 6. I noticed that I can redo the installation.

[0069] Further, in the above embodiment, the force showing the case where the claw portions 3b, 3b project outward from the pair of projecting plates 3a, 3a, as shown in Fig. 8, the pair of projecting plates 3a, 3a The claw portions 3b and 3b can be protruded inward from the inner side surface at the lower end (claim 3).

[0070] In this case, each mounting portion 3 requires a pair of protruding plates 3a, 3a, but a pair of protruding portions other than a plate shape may be used. When using the elasticity of the pair of projecting plates 3a and 3a to enable the inwardly extending claw portions 3b and 3b to be retracted, when releasing the locking with the locking portions 7b and 7b, Since it is necessary to spread these projecting plates 3a, 3a inward, it is preferable to provide another release mechanism for moving the claw portions 3b, 3b outward and retracting them when this operation is difficult. . When the pair of claw portions 3b and 3b are projected inward in this way, the engaging portions 7b and 7b are directed outward from the edge portions facing each other into the pair of fitting holes 7a and 7a. Will project.

In addition, instead of such a pair of fitting holes 7a, 7a, as shown in FIG. 8, guide groove-like fitting portions 7e, 7e that do not have edge portions opposite to each other, You can also That is, since these fitting portions 7e and 7e can be formed by recessing the front and rear side surfaces of the attachment receiving portion 7 in a groove shape, the structure of the attachment receiving portion 7 can be simplified. When the fitting portions 7e and 7e have such a guide groove shape, the locking portions 7b and 7b can be formed by projecting the upper part of the bottom surface of the groove outward. Further, such a fitting portion can be used as it is without recessing both side surfaces of the mounting receiving portion 7 in the front-rear direction.

[0072] In the above embodiment, the case where the removal gradient 3c is formed on the claw portion 3b is shown. However, as shown in Fig. 8, the removal gradient 7f is provided on the locking portion 7b of the fitting portion 7e. It can also be formed (claim 4).

[0073] The removal gradient 7f is a surface on which the protruding length of the locking portion 7b facing the attachment receiving portion 7 at the other end portion decreases toward the other attachment receiving portion 7 side. That is, since it is only necessary that the engagement with the engagement portion 7b on the side facing the mounting portion 3 at the other end of the claw portion 3b is uncertain, instead of forming the removal gradient 3c on the claw portion 3b, Such a removal gradient 7f is formed on the locking portion 7b. The same effect can be obtained. In FIG. 8, the detachment gradient 7f is formed so that the protrusion length decreases toward the lower side! Therefore, the engagement with the claw portion 3b is more smoothly and automatically released. .

[0074] Further, not only when the claw portion 3b protrudes inward as shown in FIG. 8, but also when the claw portion 3b protrudes outward as in the above embodiment, the same applies. A removal gradient 7f can be formed on the locking portion 7b. Also, the removal gradient 7f is not limited to a flat one like the removal gradient 3c, and a plurality of planes and curved surfaces that may be formed by continuous curved surfaces are discontinuous. It may be formed by being connected.

[0075] In the above-described embodiment, the force locking portion 7b shown in the case where the claw portion 3b can be retracted by elasticity may be retractable by elasticity (claim 5).

[0076] The locking portion 7b in this case may be formed, for example, on the top of an elastic resin plate standing upright from the attachment receiving portion 7, or at the upper end of the attachment receiving portion 7 in a predetermined direction in the front-rear direction. The engaging portion 7b may be urged to a predetermined position by an elastic body such as a panel while being arranged so as to be slidable back and forth to the position. The method of releasing the locking by the locking portion 7b is also arbitrary as in the case of the claw portion 3b. For example, the resin plate that supports the locking portion 7b is pushed with a finger, the mounting portion 3 or the mounting receiving portion. It is possible to provide a release mechanism so that the locking part 7b can be pulled in and released from the lock by pressing the button or lever provided on the part 7.

[0077] Further, in the above embodiment, the force indicating the case where the case of the mounting portion 3 and the fluorescent lamp lighting device 6 is made of resin. These materials are optional and, for example, insulation is reliably performed. It may be made of metal. However, if a material other than the elastic body is used, it is necessary to use a separate elastic body in order to be able to retract the claw portion 3b, etc., and not only the portion using such an elastic body but also a combination of a plurality of materials. It can also be configured.

In the above embodiment, the fluorescent lamp lighting device 6 is installed in the installation portion and the fluorescent lamp 1 is attached. However, the fluorescent lamp lighting device 6 is embedded in the installation portion or integrated. However, only the installation receiving parts 7 and 7 are provided in the installation part, and the lighting circuit etc. can be installed in other places.

[0079] Further, the connection structure with the terminals 4 ... for supplying power to the fluorescent tube 2 and the terminal receiving bracket 5 ... is also used when the mounting portions 3, 3 are locked to the mounting receiving portions 7, 7. To ensure reliable connection. In this case, it is not limited to such plugs and outlets. That is, for example, a connection structure in which the convex terminal of the attachment portion 3 presses against the contact of the attachment receiving portion 7 or a non-contact connection structure by electromagnetic induction or the like may be used.

[0080] In the above embodiment, the case where the fluorescent lamp 1 is attached has been described. However, for example, a neon tube or a towel hook may be used as long as the attachment is performed by locking the attachment portions at both ends to the attachment receiving portion. The present invention can be applied to any lengthy object such as a bar for clothes or clothes, a bar for display, or a detachable clothes basket. Since most of the long objects other than the fluorescent lamp 1 need only have an attachment receiving portion in the installation portion, the fluorescent lamp lighting device 6 is unnecessary. In addition, no electrical connection is required! ヽ If a long object is used, there is no need for a connection structure such as terminals 4 and terminal brackets 5 and so on. There is no need to consider.

Industrial applicability

[0081] By fitting the protrusions of the attachment parts at both ends of the long object into the fitting parts of the attachment receiving part of the installation part, and locking the claw parts of the protrusions to the locking parts of the fitting parts, This long object can be attached to the installation section.

[0082] Then, by releasing the claw portion of the protruding portion of one of the attachment portions by elasticity, the engagement with the engagement portion is released, and when this one attachment portion is pulled upward, a long object Since the entire body is slanted with one end portion facing upward, one side of the claw portion of the protruding portion of the attachment portion at the other end portion is lifted upward, and the removal gradient abuts on the locking portion. Then, since the protruding length of this removal gradient decreases toward one side, the claw portion can be elastically pulled in by being brought into contact with the locking portion and lifted from this one side. Therefore, the locking of the protruding portion of the other mounting portion to the locking portion of the entire claw portion can be released.

[0083] Therefore, the operation of pulling the claw portion of the protruding portion only at one of the attachment portions is performed to release the locking, and the engagement of the other attachment portion is automatically performed only by lifting the one attachment portion. Since the stop can also be released, the long object can be easily removed with one hand.
