The present invention relates to a cage car having a caster used for storing or transporting goods, packed goods, etc. in convenience stores, department stores, factories, and the like.
[0002]
[Prior art]
Conventionally, a horizontal frame having a U-shaped planar shape made of an L-shaped mold material, a back frame having a lower end attached to the horizontal frame, a pair of opposite side frames also attached to the horizontal frame, and a horizontal frame A cage comprising a mounting member formed of a rotatable metal plate having a bearing portion in which a through hole that can be inserted into a horizontal shaft disposed in the frame is provided, and a caster disposed on the bottom surface of the horizontal frame The car is known.
[0003]
[Problems to be solved by the invention]
In the above-described conventional car, since the area of the bearing portion side portion of the mounting member that is placed on the horizontal frame having a U-shaped planar shape is not sufficient, an excessive load is applied to the bearing portion, There was a problem that the bearing portion of the mounting member, the corner portion of the mounting member, and the like were damaged. Further, since the mounting member is made of metal, there is a problem that rust is generated or noise is generated due to a collision with a metal horizontal frame.
[0004]
As shown in FIG. 8, which is a partial side sectional view perpendicular to the rotation axis of the mounting member 1 of the conventional car, the end of the mounting member 1 formed by bending a metal plate is used. The bearing portion 1b having the horizontal hole 1a is integrally attached to the mounting member 1 by a suitable fixing means such as welding at a predetermined interval. A horizontal frame 2 having a U-shaped planar shape is provided with a support frame 3 to which a horizontal shaft 3a is attached at a predetermined interval. Then, by inserting the horizontal shaft 3a of the support frame 3 into the horizontal hole 1a of the bearing portion 1b of the mounting member 1, the mounting member 1 is rotated in a horizontal state and a vertical state around the horizontal shaft 3a. It is configured to be able to.
[0005]
In the conventional car as described above, the bearing portion 1b is formed so as to protrude laterally from the side wall 1c of the placement member 1, and therefore, the placement member 1 is disposed on the horizontal portion 2a of the horizontal frame 2. Only the lower corner 1d near the side wall 1c is placed. Therefore, as described above, when a load is placed on the placement member 1, an excessive load is applied to the bearing portion 1b, and the bearing portion 1b of the placement member 1 or the lower corner 1d of the placement member 1 is loaded. There are problems such as damage. Reference numeral 4 denotes a square plate attached to the horizontal portion 2 a of the horizontal frame 2, and a caster 6 is attached to the lower surface of the square plate 4 via a caster receiving frame 5.

In parallel to the hole 16c or the shaft 18, the reinforcing pipe 19 can be inserted, and a part of the flange part 20 formed in the tunnel 20a has a predetermined number (in the embodiment shown in FIG. The part 20 is formed.) It is arranged. A closed wall 20b is formed at one end of the collar portion 20, and the other end is an open, substantially semicircular open end 20c. A vertical groove 20e is formed in the upper wall facing the inner peripheral wall 20d of the flange 20 near the open end 20c, and a window hole 20f is formed in the lower wall facing the inner peripheral wall 20d below the vertical groove 20e. Is drilled.
[0014]
Reference numeral 21 denotes a lid made up of a substantially semi-cylindrical part 21a and a rectangular back part 21b connected to the substantially semi-cylindrical part 21a, which closes the open end 20c of the collar part 20, and the back part 21b of the lid 21 Projecting portions 21d that fit into the vertical grooves 20e formed in the upper wall of the inner peripheral wall 20d of the flange portion 20 are provided to protrude from the upper end portions of the opposite side wall portions 21c. In addition, a protrusion 21e that fits into the window hole 20f formed in the lower wall of the inner peripheral wall 20d of the flange portion 20 is provided in the vicinity of the lower end portion of the opposite side wall portion 21c of the back portion 21b. Yes.
[0015]
After inserting the reinforcing pipe 19 having the substantially full length of the flange portion 20 into the flange portion 20, as shown in FIG. 6, the lid body 21 is connected to the open end 20c of the flange portion 20 from above. When the lid 21 is fitted and pushed downward so that the projection 21e is inserted into the vertical groove 20e formed in the inner peripheral wall 20d of the flange 20, the protrusion 21e of the lid 21 is While fitting into the window hole 20f formed in the inner peripheral wall 20d, the protruding portion 21d of the lid 21 is fitted into the vertical groove 20e formed in the inner peripheral wall 20d of the flange portion 20 so that the flange portion 20 is opened. The end 20c is closed by the lid 21. As described above, the reinforcing pipe 19 is inserted into the flange portion 20 as necessary to reinforce the mounting member 16. In addition, it is preferable that the lower end edge 21b ′ of the square-shaped back portion 21b of the lid body 21 is configured to come into contact with the rear wall 20c ′ formed at the lower corner portion of the substantially semicircular open end 20c.
[0016]
Reference numeral 22 denotes a through hole formed in the mounting member 16 as necessary. By forming such a through hole 22, the mounting member 16 can be reduced in weight, and the mounting member 16 can be reduced in weight. It is possible to prevent rainwater or the like from accumulating on the upper surface. Moreover, 23 is a through-hole formed in the upper surface of the mounting member 16 in which the collar part 20 mentioned above was formed, and such a through-hole 23 is formed as needed.
[0017]
Reference numeral 24 denotes a cylindrical hole formed on the back surface of the mounting member 16, and the hole 24 is positioned on the opposite side of the mounting member 16 from the side on which the protruding portion 16 a ′ is formed. Two are formed in the vicinity of the corners on the back surface of the plate. Reference numeral 25 denotes a bowl-shaped grommet that is fitted into the hole 24 and is formed of rubber or soft synthetic resin. When the mounting member 16 is placed in a horizontal state and placed on the horizontal frame 10, the grommet 25 is placed on the square plate 13 attached to the lower surface of the front end portion of the side frames 10 b of the horizontal frame 10. It is configured. Thus, by arranging the grommet 25 on the back surface of the mounting member 16, it is possible to reduce the noise generated when the mounting member 16 collides with the horizontal frame 10 as the car C travels. it can.

[0019]
By forming recesses on both side portions of the side wall on the rotation side of the mounting member, an overhanging part is provided across the recess, and a bearing part is provided in the recess so that the mounting member is in a horizontal state. More parts near the edge of the side wall including the overhanging part are placed on the horizontal frame, so that an excessive load is applied to the bearing part and the bearing part is damaged, or the placing member Occurrence of troubles such as breakage of the corners and the like can be prevented.
[0020]
Since the mounting member is made of synthetic resin, rust is not generated, and noise generated by collision with the horizontal frame can be reduced.
[0021]
A hook part into which the reinforcing pipe can be inserted is formed on the back surface of the mounting member, and the open end of the hook part is opened and closed with a lid. The insertion member can be reinforced to reinforce the mounting member, and the reinforcing pipe can be easily removed from the collar portion by removing the lid.
