Abstract

PURPOSE: To manufacture a spring hanger without welding and to enhance the productivity by locating a spring supported by a lower lid and a spring pressing plate in a casing composed of a pair of opposed semicylindrical bodies, and by providing a rod locked at its upper end to the spring pressing plate and supporting at its lower end a load. CONSTITUTION: A casing 1 is composed of a pair of symmetric semicylindrical bodies 2, 3, and an upper lid 4 made into contact with arcuate edges 2a, 3a at the upper ends of the semicylindrical bodies 2, 3 and fixed by bolts 5. An arm 4 is projected from the upper lid 4, radially of the latter, and a suspending handle 4b is provided at the center thereof. Further, a lower lid 6 is fixed to arcuate edges 2a, 3a at make lower end of the semicylindrical bodies by means of bolts. A coil spring 7 is supported at its lower end by the lower lid 6, and is supported at its upper end by a spring pressing plate 8 to which a load supporting rod 10 is attached. This spring pressing plate 8 connects an arm 8 projected diametrically of the plate 8 with the arm 4a of the upper lid 4 by means of the bolts 9.

FIELD OF THE INVENTION The present invention relates to improvements in spring hangers.

[0002]

2. Description of the Related Art A cylindrical case, a spring, a spring pressing plate,
Spring hangers are known which consist of a rod depending from a spring plate. (For example, actual Kaihei 1-65995). In this type of spring hanger, the coil spring is stored in the case where the lower lid is welded in advance, the spring pressing plate and the upper lid are placed on it, and the upper lid is pressed down to the upper end of the case, and in this state the case and upper lid are welded. Configure. Since spring hangers are often used outdoors by being exposed to rain and dew, their inner and outer surfaces must be sufficiently rust-proof. Since the case has a vertical hole for locking the spring plate, spray rust-preventive agent or rust-preventive paint with this as a window. It is difficult to completely prevent rust on the inner surface. As a problem before that, the welding of the upper and lower lids is a work requiring a lot of man-hours, and from this point as well, an improvement that does not require welding has been desired.

[0003]

SOLUTION: A case is composed of a pair of symmetrical semi-cylindrical bodies, arcuate edges are provided at the upper and lower ends, respectively, to which upper and lower lids can be bolted. No need for welding,
It is only necessary to assemble each member that has been sufficiently rustproofed in advance.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings will be described. The case 1 is composed of a pair of symmetrical half cylinders 2 and 3, and has inward arcuate edges 2a and 3a at the upper and lower ends, respectively. The upper lid 4 has arc edges 2a and 3a
It contacts the inner surface of and is fixed to the arc edge with bolts 5. The upper lid 4 has an arm 4a protruding in the diameter direction and a lowering hand 4b provided at the center. The lower lid 6 is an arc edge 2 at the lower end
Bolts are fixed to the upper surfaces of a and 3a, and a hole 6a is formed in the center.

The coil spring 7 is housed in the case and supported by the lower lid 6. The spring pressing plate 8 can move up and down in the case and presses the spring 7. The spring pressing plate 8 has an arm 8a protruding on the diameter line, and can be connected to the arm 4a by a bolt 9. Therefore, the spring pressing plate 8 can be locked to the case when it is necessary for periodical inspection. The rod 10 has its upper end locked to the spring pressing plate 8, freely penetrates the lower lid, and supports the load at its lower end.

As an assembling procedure, first, a spring is placed on the lower lid, the spring pressing plate and the upper lid are placed on top of the spring, and the spring is pressed to a proper height from above. Next, the semi-cylinders 2 and 3 are approached from both sides, the pressing body is inserted, and the cylinder edge is bolted.

The lower lid 6 is pressed down by a spring retainer plate 8 via a spring 7. The purpose of bolting this to the arc edge is to prevent the lower parts of the half cylinders 2 and 3 from slipping outward. Is. Instead of this bolt, rising protrusions 2b may be provided at a plurality of positions on the tip line of the arc edge 2a as shown in FIG.

[0008]

[Effect] The welding process becomes unnecessary. Rust prevention is performed independently for each member, so completeness can be expected. A finished product can be obtained simply by assembling this member with bolts.
