  In an elevator of the type in which the mirror 2 as shown in FIG. 5 is fixed to the side wall 1 with a screw 2a, there is a demand to additionally attach a mirror frame so that the screw 2a cannot be seen from the front. In such a case, in order to attach the mirror with the mirror frame of the configuration of FIGS. 6 and 7 to the cab, it is necessary to remove the original mirror and perform the entire replacement work, which increases time and cost. There was a problem.

The present invention relates to an elevator in which a mirror is attached to a side wall of a cab, and is configured to cover an attachment device having an attachment portion and an engagement portion, and a peripheral portion of the mirror, and is engaged with the engagement portion on the back side thereof. recess and a formed lens frame for, after attaching the section mounting between the side walls and the mirror, attached to the periphery of the mirror the lens frame so that the concave portion is engaged with the engagement portion The engaging device is made of a thin plate, the engaging portion is flexible, and has a mountain-shaped cross section, and is formed to be continuous with an obtuse angle with the mounting portion. The mounting portion is inserted between the side wall and the mirror so that the engaging portion faces in the opposite direction to the side wall .

Also, the outer peripheral portion is formed on the outside of the front Symbol recess engagement when this recess engages with the engaging portion by the outer peripheral portion interferes with the locking portion, the lens frame to the mounting fixture It is the structure to do.
In a further, on the back side of the lens frame, in which recesses for screws that secure the mirror to the side walls do not interfere is formed.

  In addition, the mirror is a quadrangle, the lens frame has a square shape, and the mirror frame has a structure in which the ends of a plurality of frame pieces are brought into contact with each other. It consists of a frame piece, a lower frame piece, a right frame piece, and a left frame piece. Both ends of each frame piece are cut at 45 degrees, and the cut surfaces are brought into contact with each other to form a square shape. Is formed.

  According to the present invention, in the case of an elevator cab with a mirror as shown in FIG. 5, the lens frame can be attached while leaving the existing mirror.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a mirror, a view corresponding to FIG. 6, FIG. 2 (b) is a detailed view of a portion B of FIG. 1, FIG. 2 (a) is an upper frame piece described later from FIG. The removed explanatory view and FIG. 3 are perspective views of the fixture.

  In the figure, reference numeral 10 denotes a mirror frame, which is composed of four aluminum shape frame pieces, an upper frame piece 11, a lower frame piece 12, a right frame piece 13, and a left frame piece 14, and both end portions of each frame piece. Is a shape cut at 45 degrees, and the cut surfaces are butted against each other and welded to form a square shape.

  Reference numeral 20 denotes an attachment device in which a thin plate is bent, and has an attachment portion 21 and an engagement portion 22. The engaging part 22 has a locking part 23 having a mountain-shaped cross section, and this locking part 23 has a flexible structure formed continuously from the mounting part 21 so as to form an obtuse angle.

  The cross section of the lens frame 10 is formed with a first recess 30 for engaging with the engaging portion 22 and a second recess 31 for preventing interference with the screw 2a, as shown in FIG. 2 (a). . Further, an outer peripheral portion 32 is formed at a portion in contact with the side wall 1 so as to surround the first concave portion 30.

  In order to install the lens frame 10 of the present embodiment on the existing mirror 2, first, one or a plurality of fixtures 20 on the upper, lower, left and right sides of the mirror 2 between the side wall 1 and the mirror 2 of the cab. The attachment part 21 is inserted. Next, the installation of the lens frame 10 is completed by pressing the lens frame 10 in the direction of the side wall 1 so that the first concave portion 30 of the lens frame 10 which is fixed by welding in advance is engaged with the engaging portion 22 of each attachment device 20. To do. As a result, even when the lens frame 10 is pulled toward the inside of the car, the locking portion 23 of the engaging portion 22 interferes with the outer peripheral portion 32, so that the lens frame 10 does not fall off.

Thus, according to the present embodiment, it is possible to easily install the lens frame while leaving the existing mirror.
Further, in this embodiment, when the lens frame 10 becomes unnecessary or is replaced with another lens frame, the outer peripheral portion 32 gets over the locking portion 23 if the lens frame 10 is pulled strongly toward the opposite side wall 1. Therefore, the lens frame 10 can be removed. Furthermore, this embodiment can be applied not only to existing mirrors but also to new mirrors.

  Next, another embodiment of the present invention will be described with reference to FIG. 4 is a view corresponding to FIG. 2, and 15 is a screw screwed into the right frame piece 13 from the hole 11 a formed in the end of the upper frame piece 11, and the upper frame piece 11 and the left frame piece. 14 and the lower frame piece 12 and the left and right frame pieces 13 and 14 have the same configuration. Reference numeral 33 denotes a hole into which the screw 15 is screwed, and is formed in the left and right frame pieces 13 and 14. In the vicinity of both ends of the hole 33, a tapped hole for screwing into the screw 15 is formed.

  In order to install the lens frame 10a of the present embodiment on the existing mirror 2, first, the frame pieces 11 to 14 are assembled by screwing the screw 15 into the hole 11a and the hole portion 33 in advance to form a square-shaped mirror. The frame 10a is manufactured. Next, between the side wall 1 of the cab and the mirror 2, one or a plurality of attachment portions 20 of the attachment device 20 are inserted on each of the upper, lower, left and right sides of the mirror 2. Next, the lens frame 10 a is pressed in the direction of the side wall 1 so that the first recess 30 engages with the engaging portion 22 of each attachment device 20. Thereby, since the latching | locking part 23 of the engaging part 22 interferes with the outer peripheral part 32, the lens frame 10 does not drop.

Thus, also in the present embodiment, it is possible to easily install the lens frame while leaving the existing mirror.
In this embodiment, when the lens frame 10a is no longer needed or replaced with another lens frame, the outer peripheral portion 32 is engaged if the lens frame 10a is pulled strongly in the direction opposite to the side wall 1 as in the previous embodiment. In order to get over the stop 23, the lens frame 10a can be removed.
Further, if the frame pieces 11 to 14 are separated by removing the screws 15, the frame pieces 11 to 14 together with the attachment device 20 can be removed from the mirror 2. Therefore, in the case of this Embodiment, the latching | locking part 23 of the fixture 20 may be the structure which blocks | prevents the movement to the anti-side wall 1 direction of the lens frame 10a. Furthermore, this embodiment can be applied not only to existing mirrors but also to new mirrors.

In each of the above-described embodiments, the second recess 31 is provided so as not to interfere with the screw 2a of the mirror 2. However, when the screw 2a of the mirror 2 does not protrude, the second recess 31 may not be provided. . Further, the lens frame 10 is not limited to an aluminum shape.
Moreover, if the latching | locking part 23 of the fixture 20 is a shape which cannot remove the lens frame 10 easily, it will not be limited to the said embodiment. Furthermore, the number of installation fixtures 20 for each side of the mirror 2 may be appropriately set according to the situation. Furthermore, even if the mirror 2 has a shape other than a quadrangle, it can be similarly implemented.

It is a front view of the mirror which shows embodiment of this invention. It is the B section detailed drawing and explanatory drawing of FIG. It is a perspective view of a fixture. It is a figure which shows other embodiment of this invention. It is an example which shows the car room of the conventional elevator. This is a conventional example using a mirror frame. It is AA sectional drawing of FIG.
