According to embodiment 1 described above, the door panel 1 of the elevator includes the outer panel 2, the reinforcing member 3, and the joint weld portion 10. The outer panel 2 is joined to the reinforcing member 3 by a joint weld 10 by laser welding. The joint weld portion 10 includes a first joint end portion 11a and a joint center portion 12. The first joint end portion 11a is provided within a range of 1/10 of the length L1 from the one end portion of the reinforcing member 3. The first joining end portion 11a has a linear shape. Therefore, the reinforcing member 3 is weld-joined to the outer panel 2 at the first joint end portion 11a in a state in which sufficient joint strength is ensured. In addition, the joining center portion 12 is provided so as not to overlap the first joining end portion 11 a. The joint center portion 12 has a shape of a broken line parallel to the longitudinal direction of the reinforcing member 3. Therefore, the welding strain of the joining portion joining the center portion 12 is suppressed. Therefore, the outer panel 2 can have high design. As a result, the elevator door panel 1 can achieve both sufficient strength and high design.
The first joining end portion 11a has a line segment shape perpendicular to the longitudinal direction. Therefore, on the appearance surface 2b, a welding mark formed by the first joining end portion 11a is suppressed. The reinforcing member 3 is weld-joined to the outer panel 2 at the first joint end portion 11a in a state where sufficient joint strength is ensured. As a result, the door panel 1 can achieve both sufficient strength and high design.
The first joining end portion 11a may have the same shape as the second joining end portion 11b. For example, the first joining end portion 11a has a circular arc shape. For example, the first joining end portion 11a has a circular arc shape having a central angle smaller than 360 degrees. Therefore, the reinforcing member 3 can be joined to the outer panel 2 at the first joint end portion 11a in a state in which sufficient joint strength is ensured.
The joint weld portion 10 includes a second joint end portion 11b. The second joint end portion 11b is provided within a distance of 1/10 of the length L1 from the other end portion of the reinforcing member 3. The second joining end portion 11b has a linear shape. Therefore, the reinforcing member 3 can be joined to the outer panel 2 at the second joint end portion 11b in a state where sufficient joint strength is ensured.
The second joining end portion 11b has a circular arc shape. Therefore, the reinforcing member 3 can be joined to the outer panel 2 at the second joint end portion 11b in a state where sufficient joint strength is ensured.
The second joining end portion 11b may have the same shape as the first joining end portion 11 a. For example, the second joining end portion 11b has a line segment shape perpendicular to the longitudinal direction. For example, the second joining end portion 11b has a length of 1 or more 2-fold of the width-direction length of the flange portion 3b. For example, the second joining end portion 11b has the same length as the width-direction length of the flange portion 3b. Therefore, the second joining end portion 11b can suppress formation of a welding mark on the design surface 2b.
In addition, the 1 or more lower joining end portions 21 provided in the lower reinforcing member 4 may have the same shape as the first joining end portion 11 a. For example, 1 or more lower joining end portions 21 have a line segment shape perpendicular to the longitudinal direction. For example, 1 or more of the lower joining end portions 21 have a length of 1 or more of 2-to-1 of the width-directional length of the lower flange portion 4b. For example, 1 or more lower joining end portions 21 have the same length as the width-direction length of the lower flange portion 4b. That is, the two lower joining ends 21 substantially include the first joining end 11a and the second joining end 11b.
Fig. 4 is a view of a door panel of an elevator in embodiment 2 as viewed along arrow X. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
As shown in fig. 4, for example, the first joining end portion 11a has an elliptical shape. The first joint end portion 11a has an elliptical shape. For example, the first joining end portion 11a has an elliptical shape having a major axis whose length is 2-1 or more of the width-directional length of the flange portion 3b. For example, the first joining end portion 11a has an elliptical shape having a major axis whose length is the same as the width-direction length of the flange portion 3b.
For example, the second joining end portion 11b has an elliptical shape. For example, the second joining end portion 11b has an elliptical shape having a major axis whose length is 2-1 or more of the width-directional length of the flange portion 3b. For example, the second joining end portion 11b has an elliptical shape having a major axis whose length is the same as the width-direction length of the flange portion 3b.
According to embodiment 2 described above, the first joining end portion 11a has an elliptical shape. Therefore, the reinforcing member 3 can be joined to the outer panel 2 at the first joint end portion 11a in a state where sufficient joint strength is ensured.
The second joining end portion 11b has an elliptical shape. Therefore, the reinforcing member 3 can be joined to the outer panel 2 at the second joint end portion 11b in a state where sufficient joint strength is ensured.
In addition, when the first joining end portion 11a has an elliptical shape, the shape of the second joining end portion 11b may be the shape of the second joining end portion 11b in embodiment 1. For example, the second joining end portion 11b has a circular arc shape. For example, the second joining end portion 11b has a circular arc shape having a central angle smaller than 360 degrees. For example, the second joining end portion 11b has a line segment shape perpendicular to the longitudinal direction. For example, the second joining end portion 11b has a length of 1 or more 2-fold of the width-direction length of the flange portion 3b. For example, the second joining end portion 11b has the same length as the width-direction length of the flange portion 3b.
In addition, when the second joining end portion 11b has an elliptical shape, the shape of the first joining end portion 11a may be the shape of the first joining end portion 11a in embodiment 1. For example, the first joining end portion 11a has a line segment shape perpendicular to the longitudinal direction. For example, the first joining end portion 11a has a length of 2-1 or more of the width-directional length of the flange portion 3b.
