Heavy Duty Spring Stays

   Disclosed is a heavy duty spring stay which has the
structure to be assembled easily and safely.  The long and heavy
duty coil-spring is pushed into the stay-cover easily and safely by
the assembly device that the long shaft is passed through the
coil-spring.

   Figure 1 shows the assembly parts and device.  The inner
cover (1) and outer cover (2) are connected to be able to slide.  The
shaft (3) and pipe (4) are passed through the coil-spring (5).  The
pipe (4) is a guide for the spring (5) to slide smoothly in the outer
cover (2) without bending.  Then, the shaft (3) is passed through the
spring cover (6).  The spring (5) is pushed into the slot of the
inner cover (1) and pressed into the outer cover (2) by the spring
cover (6) in the condition that the inner cover (1) is fixed firmly.
The spring cover (6) is fixed on the outer cover by screws.  After
assembling, the shaft (3) is pulled up through the hole (7).  Figure
2 shows the assembled condition.  The spring (5) is compressed from
70 cm to 35 cm and the pressure force is 10 kg.  This spring stay has
2 pieces of spring and is assembled by manual operation easily and
safely without expensive devices.

   The pressure force of this stay is increased by increasing
the number of the spring and slot without changing the easiness and
safety of assembling.
