[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing the configuration of an elevator according to embodiment 1. In the figure, a machine room 2 is provided above an elevator shaft 1. In the machine room 2, a hoisting machine 3, a deflector sheave 4, and a control device 5 are installed.

[0010] The hoist 3 has a drive sheave 6, a hoist motor (not shown), and a hoist brake (not shown). The hoist motor rotates the drive sheave 6. The hoist brake keeps the drive sheave 6 stationary. The hoist brake also brakes the rotation of the drive sheave 6.

[0011] A suspension body 7 is wound around the drive sheave 6 and the deflector sheave 4. A plurality of ropes or belts is used as the suspension body 7. A car 8 is connected to a first end of the suspension body 7. A counterweight 9 is connected to a second end of the suspension body 7.

[0012] The car 8 and counterweight 9 are suspended within the hoistway 1 by a suspension body 7. The car 8 and counterweight 9 move up and down within the hoistway 1 by rotating the drive sheave 6. The control device 5 controls the operation of the car 8 by controlling the hoisting machine 3.

[0013] The car 8 includes a car frame 10, a cab 11, a car door 12 on the elevator panel, and a door controller 13.

[0014] A suspension body 7 is connected to the car frame 10. A car room 11 is supported by the car frame 10. The car room 11 has a car room wall that is an elevator panel. A car door 12 opens and closes the car entrance. A door controller 13 controls the opening and closing operation of the car door 12.

[0015] Landing hall doors 14, which are elevator panels, are provided at each of the landings on multiple floors. Each landing door 14 opens and closes in conjunction with the car door 12 when the car 8 lands on the floor, thereby opening and closing the landing entrance and exit.

[0016] Fig. 2 is a front view showing a main part of the car door 12 in Fig. 1. The front of the car door 12 shown in Fig. 2 faces the elevator shaft 1. The car door 12 has a door panel 21 as the front panel of the elevator, window glass 22 as the window member, a pair of glass holding frames 23 as members to be reinforced, and a reinforcing plate 24.

[0017] Here, the width direction of the door panel 21 is the X-axis direction in Fig. 2. The height direction of the door panel 21 is the Z-axis direction in Fig. 2. The thickness direction of the door panel 21 is the Y-axis direction in Fig. 2. The width direction, height direction, and thickness direction of the door panel 21 are all perpendicular to one another.

[0018] The door panel 21 has a panel main portion 21a, a pair of connecting portions 21c, and a pair of opposing portions 21b. Each connecting portion 21c and each opposing portion 21b correspond to one another. The panel main portion 21a, the pair of connecting portions 21c, and the pair of opposing portions 21b are each plate-shaped members. The panel main portion 21a, the pair of connecting portions 21c, and the pair of opposing portions 21b are each, for example, flat-plate-shaped members. The door panel 21 is produced, for example, by bending a single steel plate.

[0019] The panel main portion 21a is provided with an opening 21f, which has, for example, a rectangular shape.

[0020] Each of the connecting portions 21c protrudes from the panel main portion 21a. Each of the connecting portions 21c protrudes on the same side of the panel main portion 21a. For example, each of the connecting portions 21c protrudes perpendicularly to the panel main portion 21a. For example, the pair of connecting portions 21c protrudes from both ends of the panel main portion 21a in the width direction of the door panel 21.

[0021] Each facing portion 21b protrudes from the end of the corresponding connecting portion 21c on the side opposite to the door panel 21. The pair of facing portions 21b protrude toward each other. Each facing portion 21b is connected to the panel main portion 21a by the corresponding connecting portion 21c. Each facing portion 21b faces the panel main portion 21a. A gap is provided between each facing portion 21b and the panel main portion 21a. Each facing portion 21b is, for example, parallel to the panel main portion 21a. Each facing portion 21b has a first contact surface 21d and a second contact surface 21e. The first contact surface 21d is a surface of the facing portion 21b that faces the panel main portion 21a. The second contact surface 21e is a surface of the facing portion 21b on the opposite side to the first contact surface 21d.

[0022] The window glass 22 is arranged on the same side of the panel main portion 21a as the pair of opposing portions 21b. The window glass 22 is a window member that transmits light. The window glass 22 is, for example, a flat piece of glass. The shape of the window glass 22 is, for example, rectangular. The window glass 22 is in contact with the panel main portion 21a. The window glass 22 closes the opening 21f of the panel main portion 21a.

[0023] Each glass retaining frame 23 is arranged on the same side of the panel main portion 21a as the window glass 22. The pair of glass retaining frames 23 are arranged with the window glass 22 sandwiched between them. Each glass retaining frame 23 is arranged along the edge of the window glass 22. For example, the pair of glass retaining frames 23 are arranged along the edge of each side of the window glass 22 in the width direction of the door panel 21. Each glass retaining frame 23 is joined to the panel main portion 21a. For example, each glass retaining frame 23 is joined to the panel main portion 21a with an adhesive. For example, each glass retaining frame 23 is joined to the panel main portion 21a by welding. For example, each glass retaining frame 23 is joined to the panel main portion 21a with a stud bolt welded to the panel main portion 21a.

[0024] Each glass retaining frame 23 faces the window glass 22 in the thickness direction of the door panel 21. Each glass retaining frame 23 is abutted against the window glass 22 in the thickness direction of the door panel 21. Each glass retaining frame 23 sandwiches the window glass 22 between itself and the panel main portion 21a in the thickness direction of the door panel 21. Each glass retaining frame 23 presses the window glass 22 against the panel main portion 21a. Each glass retaining frame 23 holds the window glass 22 to the panel main portion 21a.

[0025] The reinforcing plate 24 is provided on the same side of the panel main portion 21a as the pair of opposing portions 21b. The reinforcing plate 24 is a beam-shaped member. The reinforcing plate 24 is joined to the door panel 21. For example, both end portions of the reinforcing plate 24 are joined to the pair of opposing portions 21b, respectively. The reinforcing plate 24 is connected to the panel main portion 21a of the door panel 21, the pair of connecting portions 21c, and the pair of opposing portions 21b in a ring shape. The reinforcing plate 24 reinforces the door panel 21.

[0026] The car door 12 is configured as described above. The car door 12 is attached with the first panel reinforcement device 25 and the second panel reinforcement device 26. The first panel reinforcement device 25 is attached higher than the second panel reinforcement device 26. The second panel reinforcement device 26 is attached lower than the first panel reinforcement device 25.

[0027] Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Fig. 4 is an enlarged cross-sectional view of part IV in Fig. 3. Fig. 5 is a cross-sectional view taken along line VV in Fig. 2. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 2.

[0028] The first panel reinforcement device 25 has a first mounting member 31, a first pressing member 32, a first spacer 33, a plurality of first nuts 34, and a plurality of first screws 35. Each of the first nuts 34 and each of the first screws 35 are in a one-to-one correspondence.

[0029] The first mounting member 31 is disposed on the same side of the pair of opposing portions 21b as the panel main portion 21a. The first mounting member 31 is, for example, a beam-shaped member. The first mounting member 31 is disposed, for example, with its longitudinal direction parallel to the width direction of the door panel 21. Both ends of the first mounting member 31 in the longitudinal direction are respectively abutted against the first contact surfaces 21d of the pair of opposing portions 21b. The cross-sectional shape of the first mounting member 31 perpendicular to the longitudinal direction is, for example, U-shaped.

[0030] The first pressing member 32 is disposed on the opposite side of the pair of opposing portions 21b from the panel main portion 21a. The first pressing member 32 is, for example, a beam-shaped member. The first pressing member 32 is, for example, disposed with its longitudinal direction parallel to the width direction of the door panel 21. The first pressing member 32 has a first fixing portion 32a, a first protruding portion 32b, and a pair of first contact portions 32c. Each of the first contact portions 32c is associated with each of the glass holding frames 23 in a one-to-one relationship. The first fixing portion 32a, the first protruding portion 32b, and each of the first contact portions 32c are, for example, each flat plate-shaped. The first fixing portion 32a, the first protruding portion 32b, and each of the first contact portions 32c are, for example, connected in a Z-shape in a cross section perpendicular to the longitudinal direction of the first pressing member 32.

[0031] The first fixing portion 32a has both longitudinal ends thereof abutted against the second contact surfaces 21e of the pair of opposing portions 21b. The first fixing portion 32a sandwiches the pair of opposing portions 21b between itself and the first mounting member 31.

[0032] The first protrusion 32b protrudes from the first fixing portion 32a. The first protrusion 32b protrudes, for example, from the lower end of the first fixing portion 32a. The first protrusion 32b protrudes toward the panel main portion 21a. The first protrusion 32b protrudes toward the pair of glass retaining frames 23. The first protrusion 32b faces the first mounting member 31 in the height direction of the door panel 21. The first protrusion 32b is overlapped with the first mounting member 31 in the height direction of the door panel 21, for example. The first protrusion 32b is overlapped with the lower end surface of the first mounting member 31, for example.

[0033] Each of the first contact portions 32c protrudes from the first protruding portion 32b. For example, each of the first contact portions 32c protrudes from the end of the first protruding portion 32b on the side of the panel main portion 21a. For example, each of the first contact portions 32c protrudes downward. Each of the first contact portions 32c is located along the side of the corresponding glass holding frame 23 opposite the panel main portion 21a. Each of the first contact portions 32c is pressed against the side of the corresponding glass holding frame 23 opposite the panel main portion 21a.

[0034] The first spacer 33 is disposed between the pair of opposing portions 21b. The first spacer 33 is disposed between the first mounting member 31 and the first pressing member 32. The first spacer 33 is, for example, a flat plate-shaped member. The first spacer 33 is thinner than the pair of opposing portions.

[0035] Each first nut 34 is fixed to the first mounting member 31. Each first nut 34 is disposed on the side of the first mounting member 31 opposite the first pressing member 32. Each first nut 34 is disposed, for example, on the side of the first mounting member 31 facing the panel main portion 21a. The center line of a screw hole (not shown) of each first nut 34 faces the first pressing member 32.

[0036] Each first screw 35 passes through the first holding member 32 and the first mounting member 31 and is screwed into the corresponding first nut 34. Each first screw 35 fastens the first mounting member 31 and the first holding member 32 together. Each first screw 35 secures the first mounting member 31 and the first holding member 32 together. At least one first screw 35, for example, passes through the first spacer 33 and is screwed into the corresponding first nut 34. Each first screw 35 is, for example, a flat head screw.

[0037] When the first mounting member 31 and the first pressing member 32 are fastened together, the pair of opposing portions 21b are sandwiched between the first mounting member 31 and the first fixing portion 32a. As a result, the first mounting member 31 and the first pressing member 32 are fixed to the door panel 21.

[0038] By fastening the first mounting member 31 and the first pressing member 32 together, the first spacer 33 is sandwiched between the first mounting member 31 and the first fixing portion 32a of the first pressing member 32. As a result, even if the first screw 35 is screwed tightly into the first nut 34, deformation of the first mounting member 31 and the first pressing member 32 is suppressed, so the first panel reinforcement device 25 can be firmly attached to the door panel 21.

[0039] By fixing the first pressing members 32 to the door panel 21, each first abutment portion 32c is held in a state in which it is pressed against the corresponding glass holding frame 23. This improves the bonding strength of each glass holding frame 23 to the door panel 21. Each first pressing member 32 prevents the corresponding glass holding frame 23 from coming off the panel main portion 21a. Each first pressing member 32 prevents the window glass 22 from coming off the panel main portion 21a.

[0040] The second panel reinforcement device 26 has a second mounting member 41, a second pressing member 42, a second spacer 43, a plurality of second nuts 44, and a plurality of second screws 45. Each second nut 44 and each second screw 45 are in a one-to-one correspondence.

[0041] The second mounting member 41 is disposed on the same side of the pair of opposing portions 21b as the panel main portion 21a. The second mounting member 41 is, for example, a beam-shaped member. The second mounting member 41 is disposed, for example, with its longitudinal direction parallel to the width direction of the door panel 21. Both ends of the second mounting member 41 in the longitudinal direction are respectively abutted against the first contact surfaces 21d of the pair of opposing portions 21b. The cross-sectional shape of the second mounting member 41 perpendicular to the longitudinal direction is, for example, U-shaped.

[0042] The second pressing member 42 is disposed on the opposite side of the pair of opposing portions 21b from the panel main portion 21a. The second pressing member 42 is, for example, a beam-shaped member. The second pressing member 42 is, for example, disposed with its longitudinal direction parallel to the width direction of the door panel 21. The second pressing member 42 has a second fixing portion 42a, a second protruding portion 42b, and a pair of second contact portions 42c. Each second contact portion 42c is associated with each glass holding frame 23 in a one-to-one relationship. The second fixing portion 42a, the second protruding portion 42b, and each second contact portion 42c are, for example, each flat plate-shaped. The second fixing portion 42a, the second protruding portion 42b, and each second contact portion 42c are, for example, connected in a Z-shape in a cross section perpendicular to the longitudinal direction of the second pressing member 42.

[0043] The second fixing portion 42a has both longitudinal ends thereof abutted against the second contact surfaces 21e of the pair of opposing portions 21b, respectively. The pair of opposing portions 21b is sandwiched between the second fixing portion 42a and the second mounting member 41.

[0044] The second protruding portion 42b protrudes from the second fixing portion 42a. The second protruding portion 42b protrudes, for example, from the lower end of the second fixing portion 42a. The second protruding portion 42b protrudes toward the panel main portion 21a. The second protruding portion 42b protrudes toward the pair of glass retaining frames 23. The second protruding portion 42b faces the second mounting member 41 in the height direction of the door panel 21. The second protruding portion 42b is overlapped with the second mounting member 41 in the height direction of the door panel 21, for example. The second protruding portion 42b is overlapped with the upper end surface of the second mounting member 41, for example.

[0045] Each second abutment portion 42c protrudes from the second protrusion 42b. For example, each second abutment portion 42c protrudes from the end of the second protrusion 42b on the panel main portion 21a side. For example, each second abutment portion 42c protrudes upward. Each second abutment portion 42c is aligned along the side of the corresponding glass holding frame 23 opposite the panel main portion 21a. Each second abutment portion 42c is pressed against the side of the corresponding glass holding frame 23 opposite the panel main portion 21a.

[0046] The second spacer 43 is disposed between the pair of opposing portions 21b. The second spacer 43 is disposed between the second mounting member 41 and the second pressing member 42. The second spacer 43 is, for example, a flat plate-shaped member. The second spacer 43 is thinner than the pair of opposing portions.

[0047] Each second nut 44 is fixed to the second mounting member 41. Each second nut 44 is disposed on the side of the second mounting member 41 opposite the second pressing member 42. Each second nut 44 is disposed, for example, on the side of the second mounting member 41 facing the panel main portion 21a. The center line of a screw hole (not shown) of each second nut 44 faces the second pressing member 42.

[0048] Each second screw 45 passes through the second holding member 42 and the second mounting member 41 and is screwed into the corresponding second nut 44. Each second screw 45 tightens the second mounting member 41 and the second holding member 42 together. Each second screw 45 secures the second mounting member 41 and the second holding member 42 together. At least one second screw 45, for example, passes through the second spacer 43 and is screwed into the corresponding second nut 44. Each second screw 45 is, for example, a flat head screw.

[0049] When the second mounting member 41 and the second holding member 42 are fastened together, the pair of opposing portions 21b are sandwiched between the second mounting member 41 and the second fixing portion 42a. As a result, the second mounting member 41 and the second holding member 42 are fixed to the door panel 21.

[0050] By fastening the second mounting member 41 and the second holding member 42 together, the second spacer 43 is sandwiched between the second mounting member 41 and the second fixing portion 42a of the second holding member 42. As a result, even if the second screw 45 is screwed tightly into the second nut 44, deformation of the second mounting member 41 and the second holding member 42 is suppressed, so that the second panel reinforcement device 26 can be firmly attached to the door panel 21.

[0051] By fixing the second pressing members 42 to the door panel 21, each second abutment portion 42c is held in a state in which it is pressed against the corresponding glass holding frame 23. This improves the bonding strength of each glass holding frame 23 to the door panel 21. Each second pressing member 42 prevents the corresponding glass holding frame 23 from coming off the panel main portion 21a. Each second pressing member 42 prevents the window glass 22 from coming off the panel main portion 21a.

[0052] As described above, the first panel reinforcement device 25 and the second panel reinforcement device 26 of the elevator in the first embodiment are attached to the door panel 21, respectively.

[0053] The first panel reinforcement device 25 in embodiment 1 is an elevator panel reinforcement device attached to a car door 12 that includes a door panel 21 having a panel main portion 21a, a pair of opposing portions 21b facing the panel main portion 21a, and a pair of connecting portions 21c that respectively connect the panel main portion 21a and the pair of opposing portions 21b, and a pair of glass retaining frames 23 joined to the panel main portion 21a, and is equipped with a first pressing member 32 and a first mounting member 31, and the first pressing member 32 presses the pair of glass retaining frames 23 against the panel main portion 21a, and the first pressing member 32 and the first mounting member 31 are arranged with the pair of opposing portions 21b between them and are fastened to each other to be fixed to the door panel 21 with the pair of opposing portions 21b sandwiched between them.

[0054] This makes it possible to easily improve the bonding strength between the panel main portion 21a and the pair of glass retaining frames 23 without performing any special processing on the door panel 21. As a result, the first panel reinforcing device 25 can prevent the pair of glass retaining frames 23 from coming off the panel main portion 21a. This is particularly effective when the bonding between the panel main portion 21a and the pair of glass retaining frames 23 has deteriorated in an existing elevator car door 12.

[0055] Furthermore, in the car door 12 in which the glass holding frame 23 presses the window glass 22 against the panel main portion 21a, the first panel reinforcing device 25 can prevent the window glass 22 from coming off the panel main portion 21a. This is particularly effective in the car door 12 of an existing elevator when the bond between the panel main portion 21a and the pair of glass holding frames 23 has deteriorated.

[0056] Furthermore, since the first panel reinforcing device 25 is connected to the panel main portion 21a, the pair of connecting portions 21c, and the pair of opposing portions 21b of the door panel 21 in a ring shape, the strength of the entire door panel 21 can be improved.

[0057] Furthermore, when attaching the first panel reinforcement device 25 to the door panel 21, no cutting work is required on the door panel 21, and no noise is generated due to the cutting work, so work is less likely to be restricted by time of day. For example, work can be done at night on the door panel 21 of an elevator installed in a residence.

[0058] Furthermore, when attaching the first panel reinforcing device 25 to the door panel 21, welding to the door panel 21 is not required, and no special fire prevention equipment is required.

[0059] Furthermore, the first panel reinforcing device 25 can be easily attached to the car door 12 while the car door 12 is attached to the elevator.

[0060] The first panel reinforcement device 25 in embodiment 1 is provided with a first spacer 33 that is arranged between the first pressing member 32 and the first mounting member 31 and between a pair of opposing portions 21b, and when the first pressing member 32 and the first mounting member 31 are tightened together, the first spacer 33 is sandwiched between the first pressing member 32 and the first mounting member 31.

[0061] This prevents deformation of the first mounting member 31 and the first pressing member 32 even when the first screw 35 is screwed tightly into the first nut 34, allowing the first panel reinforcement device 25 to be firmly attached to the door panel 21.

[0062] The second panel reinforcement device 26 in embodiment 1 is an elevator panel reinforcement device attached to a car door 12 that includes a door panel 21 having a panel main portion 21a, a pair of opposing portions 21b facing the panel main portion 21a, and a pair of connecting portions 21c that respectively connect the panel main portion 21a and the pair of opposing portions 21b, and a pair of glass retaining frames 23 joined to the panel main portion 21a, and is provided with a second pressing member 42 and a second mounting member 41, and the second pressing member 42 presses the pair of glass retaining frames 23 against the panel main portion 21a, and the second pressing member 42 and the second mounting member 41 are arranged with the pair of opposing portions 21b between them and are fastened to each other to be fixed to the door panel 21 with the pair of opposing portions 21b sandwiched between them.

[0063] As a result, the second panel reinforcing device 26 has the same effect as the first panel reinforcing device 25.

[0064] The second panel reinforcement device 26 in embodiment 1 is provided with a second spacer 43 that is arranged between the second pressing member 42 and the second mounting member 41 and between a pair of opposing portions 21b, and when the second pressing member 42 and the second mounting member 41 are tightened together, the second spacer 43 is sandwiched between the second pressing member 42 and the second mounting member 41.

[0065] As a result, the second panel reinforcing device 26 has the same effect as the first panel reinforcing device 25.

[0067] While the first panel reinforcement device 25 in the first embodiment described above includes a first mounting member 31 and a first spacer 33, the first panel reinforcement device 55 in the second embodiment includes a first mounting member 61 instead of the first mounting member 31 and the first spacer 33. The first mounting member 61 is the first mounting member 31 provided with a pair of first recessed portions 61a and a first protruding portion 61b. Similarly, the second panel reinforcement device 26 in the first embodiment described above includes a second mounting member 41 and a second spacer 43, but the second panel reinforcement device in the second embodiment includes a second mounting member instead of the second mounting member 41 and the second spacer 43. The second mounting member is the second mounting member 41 provided with a pair of second recessed portions and a second protruding portion.

[0068] Each first recessed portion 61a corresponds to a corresponding opposing portion 21b in a one-to-one relationship. Each first recessed portion 61a is provided at both longitudinal end portions. Each first recessed portion 61a is recessed on the side opposite the first pressing member 32. Each first recessed portion 61a is recessed, for example, on the side of the panel main portion 21a. The depth dimension of each first recessed portion 61a in the thickness direction of the door panel 21 is smaller than the thickness dimension of the corresponding opposing portion 21b. Each first recessed portion 61a abuts against the corresponding opposing portion 21b.

[0069] The first protrusion 61b is provided between the pair of first recessed portions 61a in the first mounting member 61. Each first protrusion 61b protrudes toward the first pressing member 32. For example, each first protrusion 61b protrudes on the side opposite the panel main portion 21a. The protrusion dimension of each first protrusion 61b in the thickness direction of the door panel 21 is smaller than the thickness dimension of the pair of opposing portions 21b.

[0070] When the first mounting member 61 and the first pressing member 32 are fastened together, the pair of opposing portions 21b are sandwiched between the pair of first recessed portions 61a and the pair of first fixed portions 32a, respectively. As a result, the first mounting member 61 and the first pressing member 32 are fixed to the door panel 21.

[0071] The first protrusion 61b and the first fixing portion 32a are pressed against each other by fastening the first mounting member 61 and the first pressing member 32. As a result, even if the first screw 35 is screwed tightly into the first nut 34, deformation of the first mounting member 61 and the first pressing member 32 is suppressed, and the first panel reinforcement device 55 can be firmly attached to the door panel 21.

[0072] As described above, the first panel reinforcement device 55 of the elevator in the second embodiment is attached to the door panel 21.

[0073] The second panel reinforcement device of the elevator in the second embodiment is attached to the car door 12 in the same manner as the first panel reinforcement device 55. The second attachment member of the second panel reinforcement device functions in the same manner as the first attachment member 61 of the first panel reinforcement device 55.

[0074] The first panel reinforcement device 55 in embodiment 2 is an elevator panel reinforcement device attached to a car door 12 that includes a door panel 21 having a panel main portion 21a, a pair of opposing portions 21b facing the panel main portion 21a, and a pair of connecting portions 21c that respectively connect the panel main portion 21a and the pair of opposing portions 21b, and a pair of glass retaining frames 23 joined to the panel main portion 21a, and is equipped with a first pressing member 32 and a first mounting member 61, and the first pressing member 32 presses the pair of glass retaining frames 23 against the panel main portion 21a, and the first pressing member 32 and the first mounting member 61 are arranged with the pair of opposing portions 21b between them and are fastened to each other to be fixed to the door panel 21 with the pair of opposing portions 21b sandwiched between them.

[0075] As a result, the first panel reinforcement device 55 for an elevator in the second embodiment has the same effect as the first panel reinforcement device 25 for an elevator in the first embodiment.

[0076] In the first panel reinforcement device 55 of embodiment 2, the first mounting member 61 has a first protrusion 61b that protrudes toward the first pressing member 32, and when the first pressing member 32 and the first mounting member 61 are tightened together, the first protrusion 61b and the first mounting member 61 are pressed together.

[0077] This prevents deformation of the first mounting member 61 and the first pressing member 32 even when the first screw 35 is screwed tightly into the first nut 34, allowing the first panel reinforcement device 55 to be firmly attached to the door panel 21.

[0078] Furthermore, since there is no need to provide a member corresponding to the first spacer 33 of the first embodiment in addition to the first mounting member 61, the first panel reinforcement device 55 can be easily attached to the car door 12.

[0079] The second panel reinforcement device in embodiment 2 is an elevator panel reinforcement device attached to a car door 12 that includes a door panel 21 having a panel main portion 21a, a pair of opposing portions 21b facing the panel main portion 21a, and a pair of connecting portions 21c that respectively connect the panel main portion 21a and the pair of opposing portions 21b, and a pair of glass retaining frames 23 joined to the panel main portion 21a, and is provided with a second pressing member 42 and a second mounting member, and the second pressing member 42 presses the pair of glass retaining frames 23 against the panel main portion 21a, and the second pressing member 42 and the second mounting member are arranged with the pair of opposing portions 21b between them and are fastened to each other to be fixed to the door panel 21 with the pair of opposing portions 21b sandwiched between them.

[0080] As a result, the second panel reinforcing device has the same effect as the first panel reinforcing device 55.

[0081] In the second panel reinforcement device of embodiment 2, the second mounting member has a second protrusion that protrudes toward the second pressing member 42, and when the second pressing member 42 and the second mounting member are tightened together, the second protrusion and the second mounting member 42 are pressed together.

[0082] As a result, the second panel reinforcing device has the same effect as the first panel reinforcing device 55.

[0083] In the first and second embodiments, the panel with a reinforcement device is one in which the first panel reinforcement device 25, the second panel reinforcement device 26, the first panel reinforcement device 55, or the second panel reinforcement device is attached to the car door 12. The panel with a reinforcement device has the same effects as the first panel reinforcement device 25, the second panel reinforcement device 26, the first panel reinforcement device 55, or the second panel reinforcement device.

[0084] In the first and second embodiments, the component to be reinforced is not limited to the glass-retaining frame 23, and may be, for example, a reinforcing member fixed to the panel main portion 21a. When a component other than the glass-retaining frame 23 is the component to be reinforced, only the pressing member may be replaced with a pressing member suitable for the component to be reinforced. This allows for the components other than the pressing member to be standardized.

[0085] In the first and second embodiments, the first protrusion 32b may be pressed against the pair of glass holding frames 23, thereby also serving as the pair of first abutment portions 32c. In this case, it is not necessary to provide a pair of first abutment portions 32c separate from the first protrusion 32b. Similarly, in the first and second embodiments, the second protrusion 42b may be pressed against the pair of glass holding frames 23, thereby also serving as the pair of second abutment portions 42c. In this case, it is not necessary to provide a pair of second abutment portions 42c separate from the second protrusion 42b.

[0086] In the first and second embodiments, instead of providing the first protrusion 32b and the first abutment portion 32c on the first pressing member 32, the first protrusion and the first abutment portion may be provided on the first mounting member 31 or the first mounting member 61. Similarly, in the first and second embodiments, instead of providing the second protrusion 42b and the second abutment portion 42c on the second pressing member 42, the second protrusion and the second abutment portion may be provided on the second mounting member 41.

[0087] In the first and second embodiments, a pair of opposing portions spaced apart in the height direction of the door panel 21 may be provided, and the pair of opposing portions may be sandwiched between the first mounting member 31 or the first mounting member 61 and the first pressing member 32.
