(Prior Art and Problems Thereof) In this type of hanger, a pair of left and right hanger arms that can be opened and closed is provided with support portions inside the lower ends of the hanger arms that support two portions on the left and right sides of the bottom of the automobile body. But,
As a general-purpose transport hanger that can be applied to a plurality of types of automobile bodies in which the shape and position of the supported portion are different, for example, as described in Japanese Utility Model Application Laid-Open No. 57-74311, a hanger support portion has a spring. It is known that a plurality of movable attachments, which can be pushed down against the urging force of, are arranged side by side in one direction.

In this conventional hanger with a movable attachment, even if the position of the supported portion changes in the parallel direction of the movable attachment due to the different type of automobile body that it supports,
It is possible to position the supported part in the movable attachment parallel direction by the movable attachment that is not pushed down by the supported part and is kept protruding.However, the supported part of the vehicle body is positioned in the direction orthogonal to the movable attachment parallel direction. The support cannot be positioned. Also, the size of each movable attachment is limited in terms of strength, and there is a limit to narrowing the interval between adjacent movable attachments, so if reliable positioning is possible even if the position of the supported portion changes slightly. It was difficult to tighten, and in the end, it was configured to fit only a few kinds of car bodies, and it could not be utilized as a truly versatile transport hanger.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, the present invention provides a lift limit that protrudes upward from a support surface to each support portion of a transport hanger that supports an automobile body or the like. A plurality of rows of virtual lines in the front-rear longitudinal direction, which are supported on the support surface so as to be able to move up and down and urged in the upward direction by a spring, between a position and a lower limit position that does not project from the support surface; Conveyance arranged at intersections of the left and right imaginary lines in the left and right direction, and at least one of the imaginary vertical lines in the plurality of lines and the left and right imaginary lines in the plurality of lines is slightly inclined in the same direction. We propose a hanger for you.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached exemplary drawings.

In FIG. 1 and FIG. 2, reference numeral 1 is a transporting movable body, which is suspended by a drive trolley 3 and a driven trolley 4 which are movably supported by a guide rail 2 which is erected. It is provided with a hanger 6 consisting of openable and closable hanger arms 5a, 5b. The drive trolley 3 comprises wheels 8 driven by a motor 7. Each of the hanger arms 5a, 5b is provided with a pair of front and rear support parts 9a, 9b on the inner side of the lower end thereof. Supported.

As shown in FIGS. 3 and 4, each of the supporting portions 9a and 9b has an ascending limit position that protrudes upward from a rectangular supporting surface 11 that is long in the direction and a descending limit position that does not protrude from the supporting surface 11. A plurality of rows of virtual longitudinal lines 14 in the front-rear longitudinal direction and virtual lines 15 of horizontal rows in the horizontal direction 15 are formed on the support surface 11 by pins 13 that are supported so as to be able to move up and down and urged in the upward direction by a spring 12. It is arranged at the intersection position with, and the front and rear vertical virtual lines 14 of the plurality of rows are not inclined in the left and right lateral directions,
Only the left and right virtual lines 15 are inclined in the front-rear direction in a parallel state as shown in the figure. The pitches of the pins 13 in the front-rear direction and the left-right lateral direction are the same, and the gaps between the adjacent pins 13 are set to be sufficiently smaller than the outer diameter of the pins 13.

Each pin 13 is a flange that penetrates the top plate 16 and the intermediate plate 17 that form the support surface 11 in the vertical direction and that abuts the bottom of the top plate 16.
18 and each pin 13 between this flange 18 and the intermediate plate 17
A compression coil spring 12 is loosely fitted in. Reference numeral 19 is a support arm continuously provided from the hanger arms 5a and 5b,
The support portions 9a and 9b are placed and fixed on the support arm 19 via a bottom plate 20 thereof. The bottom plate 20 is omitted and the intermediate plate
A support arm may be fixed to the bottom of the 17. In this case, the pin 13 is not arranged at the place where the support arm is attached.

In the supporting portions 9a and 9b shown in FIG. 5, the plurality of rows of the left-right horizontal imaginary lines 15 are slightly inclined in the front-rear direction in a parallel state, and the plurality of rows of front-rear vertical imaginary lines 14 are also in the left-right lateral direction in a parallel state. The pin 13 is disposed at an intersection of these virtual lines 14 and 15 with a slight inclination. Of course, the left and right horizontal imaginary lines 15 of the plurality of rows may not be tilted in the front-rear direction, but only the front and back vertical imaginary lines 14 of the plurality of rows may be tilted slightly in the left-right lateral direction in a parallel state.

When the vehicle body 10 is supported by the hanger 6 having the supporting portions 9a and 9b as described above, two portions, front and rear, on both left and right sides of the bottom portion of the vehicle body 10 are supported by the supporting portion 9a as shown in FIGS. 1 and 2. , 9b, but at this time, as shown in FIG. 3 to FIG. 5, the supporting surface 1 of the supporting portions 9a, 9b.
Regardless of the shape and size of the supported portion 21 (frame member, sill, etc. at the bottom of the body) that faces 1, the supported portion 21 has all the pins 13 located at the position where it abuts the bottom surface of the spring 12. Support surface 11 while pushing down against the biasing force
You can get on. And all the pins 13 that are not pushed down on the bottom surface of the supported portion 21
The pin 13 protruding adjacent to the side of the supported portion 21 remains because it remains protruding from the supporting surface 11 by the urging force of
However, it serves as a stopper that blocks the horizontal movement of the supported portion 21 on the support surface 11, and positions the automobile body 10.

However, as shown in FIG. 3, when the left and right imaginary lines 15 which are the center lines of the left and right lateral rows of the pins 13 are slightly inclined in the front-rear direction in the parallel state, both front and rear sides of the supported portion 21 are supported. When the side 21a is long in the lateral direction, the two side edges 21a are adjacent to each other with a slight gap in the front and back (pins 13 in FIG. 3).
(See 13a, 13b), there is more chance of being located in the middle of the two pins 13, and the pin (see pin 13a in FIG. 3) protruding from the outside of the side 21a is the side of the two pins 13 concerned. The play allowance of the supported portion 21 in the front-rear direction is reduced in the vicinity of 21a. That is, when the horizontal left / right imaginary line 15 that is the center line of the horizontal row of the pins 13 is slightly inclined in the front / rear direction in the parallel state, the positioning accuracy of the supported portion 21 in the front / rear vertical direction is improved.

Further, as shown in FIG. 5, when the front-rear vertical direction virtual line 14 which is the center line of the front-rear vertical direction row of the pins 13 is slightly inclined in the horizontal direction in the parallel state, Both sides
When 21b is long in the front-rear lengthwise direction, the side 21b has an opportunity to be located in the middle of two pins 13 (see pins 13c and 13d in FIG. 5) adjacent to each other with a slight gap in the left-right direction. Of the two pins 13, a pin projecting outside the side edge 21b (see the pin 13c in FIG. 3) comes close to the side edge 21b, and the left and right sides of the supported portion 21 increase. Reduce play allowance in the direction. That is, when the front-rear vertical direction virtual line 14 which is the center line of the front-rear vertical direction row of the pins 13 is slightly inclined in the left-right lateral direction in the parallel state, the horizontal-lateral positioning accuracy of the supported portion 21 is improved. .

(Operation and effect of device) As described above, according to the transport hanger of the present invention, even if the shape or position of the supported portion in the vehicle body is not constant, the hanger side that receives the supported portion is Since the support portion has a large number of pins that can be pushed down against the urging force of the spring, the pins are arranged at the intersections of the front and rear vertical imaginary lines of a plurality of rows and the left and right lateral imaginary lines of a plurality of rows. Pins that are not pushed down by the bottom surface of the supported portion and remain in the protruding state prevent lateral movement of the supported portion and longitudinal movement in the front-rear direction, ensuring that the supported portion falls off the support portion. Can be prevented.

Moreover, at least one of the plurality of rows of front-rear vertical imaginary lines and the plurality of rows of left-right horizontal imaginary lines is slightly inclined in the same direction, so that the side of the supported portion is a pin in the front-rear vertical row. Of the pins in the left and right lateral rows, there is more opportunity to come close to the protruding pins in at least one row, and the play allowance of the supported part on the supporting surface is reduced to improve positioning accuracy and improve safety. Can be raised.
