JP 2006-253531 A Japanese Patent No. 4140431 Japanese Patent No. 4626672 Japanese Patent No. 4706485 Japanese Patent No. 5197245 Japanese Utility Model Publication No. 60-158745

  By the way, the conventional attachment mechanism, in particular, the fixing of the electronic device to the rail is fixed to the rail by using a plurality of parts with the fixing claw and the protrusion of the attachment plate.

  In this case, in the structure in which the slide portion is pulled out, the pulling operation using the tool is less likely to apply force than the pressing operation with a finger. Moreover, since the slide part is attached to and detached from the rail while pulling, it is necessary to pull the slide part with one hand and hold it with the other hand while holding the device. There is a problem of poor workability.

  The present invention has been made in consideration of such problems, and an object of the present invention is to provide an attachment mechanism for an article that can be attached and detached with one hand and can be easily attached to and detached from a narrow place.

[1] An article attachment mechanism according to the present invention includes an attachment plate to which an article is fixed, a slide plate attached to the attachment plate and slidable in both directions, and biasing the slide plate in one direction. An attachment mechanism for attaching an article to the rail by engaging and supporting the rail with the attachment plate and the slide plate, and the attachment plate is provided on the rail. A pair of first claw portions formed with a first recess with which one side portion engages, and a first fixing portion to which one end portion of the elastic member is fixed; A pair of second claw portions formed with a second recess portion with which the other side portion of the rail is engaged, and a second fixing portion to which the other end portion of the elastic member is fixed, the first recess portion And each of the second recesses has a shape in which a gap narrows toward the bottom, The fixing portion and the second fixing portion are opposed to each other along the urging direction of the elastic member, and the first claw portion and the second claw portion approach each other by the urging force of the elastic member. In relation, it is provided on the mounting plate and the slide plate, and the slide plate is exposed to the outside beyond the mounting plate, and has a tab whose tip is an operation surface.

  First, the first fixing portion and the second fixing portion are separated from each other by the biasing of the elastic member, and the first claw portion and the second claw portion are close to each other. Thereby, one side part of a rail engages with each 1st crevice of a pair of 1st claw parts in a mounting plate, and the other side part of a rail in each 2nd crevice of a pair of 2nd claw parts in a slide plate Engage. In this case, since the first recess and the second recess each have a shape in which the gap becomes narrower toward the bottom, one side of the rail is fixed to each first recess by point contact or line contact. The other side is fixed to each second recess by point contact or line contact. That is, the mounting plate is fixed to one side portion of the rail by the first recess of the first claw portion by point contact or line contact, and the slide plate is fixed to the other side portion of the rail by the second recess portion of the second claw portion. The article fixed by point contact or line contact and fixed to the mounting plate is fixed to the rail via the mounting bracket.

  In particular, the slide plate has a tab that is exposed to the outside beyond the mounting plate and that has a tip portion as an operation surface. For this reason, the slide plate can be slid in both directions by simply operating the operation surface with one hand, for example, and it is easy to fix the mounting bracket to which the article is attached to the rail and to remove the mounting bracket from the rail. Moreover, it is easy to attach and detach the mounting bracket to a narrow place.

[2] In the present invention, the pair of second claw portions are bent at a bending angle of 45 ° ≦ θ <90 °, and the distance between the bottom portions of the pair of second claw portions facing each other is Da. When the distance between the end portions facing each other is Db, it is preferable that Da <Db.

  For example, when the pair of second claw portions are bent at a folding angle of 90 °, the other side portion of the rail is in line contact with the second concave portion of the second claw portion, or the second claw portion. The ridge line of the outer surface that constitutes the second recess and the surface of the rail make point contact, and the ridge line of the outer surface that constitutes the second recess and the rear surface of the rail make point contact. Alternatively, the ridge line on the inner surface that forms the second recess of the second claw portion and the surface of the rail make point contact, and the ridge line of the inner surface that forms the second recess and the rear surface of the rail make point contact.

  On the other hand, when the distance between the opposite ends of the pair of second claw portions of the slide plate is larger than the distance between the opposite bottom portions of the pair of second claw portions, the pair of second claw portions When viewed in the sliding direction of the slide plate, it becomes an eight-letter shape. Therefore, the other side portion of the rail is fixed to the second claw portion by point contact. In particular, the ridge line on the outer surface that forms the second recess of the second claw portion and the surface of the rail make point contact, and the ridge line of the inner surface that forms the second recess and the rear surface of the rail make point contact. For this reason, the slide plate is firmly fixed to the rail, and the lateral displacement of the slide plate is prevented, and accordingly, the lateral displacement of the mounting bracket can also be prevented.

[3] In the present invention, it is preferable that the mounting plate has a structure for fixing the article with screws or rivets.

  Conventionally, since it has been difficult to detach the mounting bracket from the rail, when detaching the article from the rail, the article is detached from the mounting bracket while the mounting bracket remains on the rail. Therefore, there is a problem that the article cannot be firmly fixed to the mounting bracket, and the article is easily detached from the mounting bracket.

  On the other hand, in the present invention, when the article is attached to or detached from the rail, the operation surface of the slide plate may be operated to remove the article from the rail together with the attachment bracket. Even if firmly fixed, the article can be easily attached to and detached from the rail. Accordingly, the article can be firmly fixed to the mounting bracket, and the problem that the article is easily detached from the mounting bracket can be solved.

  As described above, according to the article attachment mechanism of the present invention, it is possible to perform the detaching operation with one hand, and it is also easy to detach to a narrow place or the like.

FIG. 5A is a perspective view showing the slide plate as viewed from the back side, and FIG. 5B is an enlarged view of a state in which the other side portion of the rail (shown by a two-dot chain line) is fixed to the second claw portion of the slide plate. FIG. It is a figure which expands and shows the state by which the other side part (it shows with a dashed-two dotted line) of a rail was fixed when the 2nd nail | claw part of a slide plate is bent with the bending angle = 90 degree.

  Hereinafter, an embodiment of an article attachment mechanism according to the present invention will be described with reference to FIGS.

  First, as shown in FIGS. 1 and 2, an article attachment mechanism 10 according to the present embodiment includes, for example, a metal attachment plate 14 on which an article 12 (see a two-dot chain line) is fixed, and an attachment plate. For example, the mounting bracket 20 includes a metal slide plate 16 that is slidable in both directions and has an elastic member 18 that biases the slide plate 16 in one direction. Then, the rail 22 is engaged and supported by the mounting plate 14 and the slide plate 16, and the article 12 is indirectly attached to the rail 22. The elastic member 18 is preferably a compression spring, for example.

  As shown in FIG. 3, the mounting plate 14 includes a flat plate portion 24 on which the article 12 is fixed, a pair of side plate portions 26 that rise from the side surface of the flat plate portion 24 toward the rail 22, and a front surface of the flat plate portion 24. And two front plate portions 28 formed at regular intervals.

  The flat plate portion 24 is formed with a through hole 30 through which, for example, a screw or a rivet is inserted in a corner portion. That is, the mounting plate 14 has a structure for fixing the article 12 with screws or rivets.

  As shown in FIGS. 4A and 4B, each side plate portion 26 includes a pair of first claw portions 34a (see FIG. 3) in which a first recess 32a with which one side portion 22a of the rail 22 is engaged is formed. It has the 1st fixing | fixed part 36a to which one end part of the elastic member 18 was fixed.

  The first claw portion 34 a is provided together with the side plate portion 26 in a state of rising substantially perpendicular to the flat plate portion 24 of the mounting plate 14. As shown in FIG. 4B, the first recess 32a of the first claw portion 34a has a shape in which the gap becomes narrower toward the bottom 38a.

  The first fixed portion 36a is formed by bending a part of the flat plate portion 24 to the back surface side where the rail 22 is located, for example, by bending a sheet metal.

  As shown in FIG. 3, the slide plate 16 is slidably attached to the back surface side of the flat plate portion 24 of the attachment plate 14, and is engaged with the other side portion 22 b (see FIG. 4A) of the rail 22. A pair of second claw portions 34b formed with 32b, a second fixing portion 36b to which the other end of the elastic member 18 is fixed, and a first fixing portion 36a are inserted so that the slide plate 16 can slide. And a through hole 40 for the purpose.

  Unlike the first claw portion 34a described above, the second claw portion 34b is bent with respect to the slide plate 16 in a range where the bending angle θ is 45 ° ≦ θ <90 °. Accordingly, when the distance between the bottoms facing each other of the pair of second claw portions 34b is Da and the distance between the ends facing each other is Db, the relationship Da <Db is established. Moreover, the 2nd recessed part 32b of the 2nd nail | claw part 34b has a shape where a clearance gap becomes narrow toward the bottom part 38b, as shown to FIG. 4A and 4B.

  The second fixing portion 36b of the slide plate 16 is formed by bending a part of the slide plate 16 to the back side where the rail 22 is located, for example, by bending a sheet metal.

  That is, the first fixing portion 36a and the second fixing portion 36b face each other along the biasing direction of the elastic member 18, and the first claw portion 34a and the second claw portion 34b are biased by the biasing force of the elastic member 18. Are provided on the mounting plate 14 and the slide plate 16 in such a positional relationship as to approach each other.

  Furthermore, the slide plate 16 has a tab 42 that extends in the longitudinal direction and passes between the two front plate portions 28 of the mounting plate 14. That is, the tab 42 is exposed outward (front side) beyond the mounting plate 14. Further, the tab 42 is bent at a substantially right angle with respect to the slide plate 16 to form an operation surface 44 by an operator, for example.

  Next, an example of a method for attaching the article 12 to the rail 22 using the mounting bracket 20 will be described.

  First, the article 12 is fixed to the surface of the flat plate portion 24 of the mounting plate 14 using screws or rivets.

  The operation surface 44 of the slide plate 16 is pressed against the urging force of the elastic member 18 so that the first claw portion 34a of the mounting plate 14 and the second claw portion 34b of the slide plate 16 are separated from each other. Then, the first concave portion 32a of the first claw portion 34a is engaged with one side portion 22a of the rail 22, and then the pressure on the operation surface 44 is weakened so that the first claw portion 34a and the second claw portion 34b are connected. The second concave portion 32b of the second claw portion 34b is engaged with the other side portion 22b of the rail 22 while being brought close to each other. Thereafter, by stopping the pressing on the operation surface 44, the first claw portion 34 a and the second claw portion 34 b sandwich the rail 22, whereby the mounting bracket 20 to which the article 12 is fixed is attached to the rail 22. Become.

  When removing the mounting bracket 20 from the rail 22, the procedure may be reversed. For example, by pressing the operation surface 44 of the slide plate 16 exposed from the mounting plate 14 in the direction of the mounting plate 14, Since the first claw portion 34a and the second claw portion 34b are separated from each other, the first claw portion 34a and the one side portion 22a of the rail 22 are disengaged, and the second claw portion 34b and the other side of the rail 22 are further disengaged. The engagement with the side portion 22b is released. Thereby, the mounting bracket 20, that is, the article 12 can be easily detached from the rail 22.

  Thus, in the article attachment mechanism according to the present embodiment, the first fixing portion 36a and the second fixing portion 36b are separated from each other by the biasing of the elastic member 18, and the first claw portion 34a and the first claw portion 34a are separated from each other. The two claw portions 34b come close to each other. Thereby, one side part 22a of the rail 22 engages with each 1st recessed part 32a of a pair of 1st nail | claw part 34a in the attachment plate 14, and each 2nd recessed part of a pair of 2nd claw part 34b in the slide plate 16 is obtained. The other side 22b of the rail 22 is engaged with 32b.

  In this case, since the first concave portion 32a and the second concave portion 32b have shapes in which the gaps become narrower toward the bottom portions 38a and 38b, respectively, one side portion 22a of the rail 22 makes point contact with each first concave portion 32a. Alternatively, the other side portion 22b of the rail 22 is fixed to each second recess 32b by point contact or line contact.

  That is, the mounting plate 14 is fixed to the one side portion 22a of the rail 22 by point contact or line contact by the first recess portion 32a of the first claw portion 34a, and the slide plate 16 is fixed to the second recess portion of the second claw portion 34b. The article 12 fixed to the other side portion 22b of the rail 22 by point contact or line contact by 32b and fixed to the mounting plate 14 is fixed to the rail 22 via the mounting plate 14.

  In particular, the slide plate 16 has a tab 42 that is exposed to the outside beyond the mounting plate 14 and that has a distal end portion as an operation surface 44. For this reason, the slide plate 16 can be slid in both directions only by operating the operation surface 44 with one hand, for example, the mounting bracket 20 to which the article 12 is attached is fixed to the rail 22, and the rail of the mounting bracket 20 is mounted. The mounting bracket 20 can be easily detached from the 22 and the mounting bracket 20 can be easily attached to and detached from the narrow portion.

  In the present embodiment, the pair of second claw portions 34b are bent in a range where the bending angle θ is 45 ° ≦ θ <90 °, and the distance between the bottom portions of the pair of second claw portions 34b facing each other. Da <Db, where Da is the distance between the opposite end portions and Db.

  For example, when the pair of second claw portions 34b are bent at a bending angle θ = 90 °, as shown in FIG. 6, the other side portion 22b of the rail 22 has a second recess portion of the second claw portion 34b. 32b, or one ridge line 50a of the outer surface constituting the second recess 32b of the second claw portion 34b and the surface of the rail 22 are in point contact (indicated by a black circle), and the second recess 32b is The other ridge line 50b of the outer side surface constituting the point and the back surface of the rail 22 are in point contact (indicated by a black circle). Alternatively, one ridge line 52a on the inner surface constituting the second recess 32b of the second claw portion 34b and the surface of the rail 22 are in point contact (indicated by a white circle), and the other inner surface constituting the second recess 32b The ridgeline 52b and the back surface of the rail 22 are in point contact (indicated by white circles). That is, since the rail 22 makes point contact with two ridge lines located on the same side surface of the second claw portion 34b, for example, sufficient durability cannot be obtained with respect to a lateral force, and the rail 22 is liable to be laterally displaced. .

  On the other hand, as shown in FIG. 5A, the distance Db between the opposed ends of the pair of second claw parts 34b of the slide plate 16 is the distance between the opposed bottom parts of the pair of second claw parts 34b. When it is larger than Da, when the pair of second claw portions 34b is viewed in the sliding direction of the slide plate 16, it becomes an eight-letter shape.

  Therefore, as shown in FIG. 5B, the other side portion 22b of the rail 22 comes into point contact with two ridge lines located on different side surfaces of the second claw portion 34b. That is, one ridge line 50a of the outer surface constituting the second recess 32b of the second claw portion 34b and the surface of the rail 22 are in point contact (indicated by a black circle), and the other inner surface constituting the second recess 32b is contacted. The ridgeline 52b and the back surface of the rail 22 are in point contact (indicated by white circles). For this reason, the slide plate 16 is firmly fixed to the rail 22 and, for example, a sufficient durability against a lateral force can be obtained. Accordingly, the lateral displacement of the slide plate 16 is prevented, and the lateral displacement of the mounting plate 14 can be prevented.

  In the present embodiment, the mounting plate 14 has a structure for fixing the article 12 with a screw or rivet, that is, a through hole 30 through which the screw or rivet or the like is inserted.

  Conventionally, since it has been difficult to detach the mounting bracket from the rail, when detaching the article from the rail, the article is detached from the mounting bracket while the mounting bracket remains on the rail. Therefore, there is a problem that the article cannot be firmly fixed to the mounting bracket, and the article is easily detached from the mounting bracket.

  On the other hand, in the present embodiment, when the article 12 is attached to and detached from the rail 22, the operation surface 44 of the slide plate 16 is operated to remove the article 12 from the rail 22 together with the mounting bracket 20. Therefore, even if the article 12 is firmly fixed to the mounting bracket 20, the article 12 can be easily attached to and detached from the rail 22. Thereby, the article 12 can be firmly fixed to the mounting bracket 20, and the problem that the article 12 is easily detached from the mounting bracket 20 can be solved.

  It should be noted that the article attachment mechanism according to the present invention is not limited to the above-described embodiment, and various structures can be adopted without departing from the gist of the present invention.
