, bouncing device
30
is activated to push the sliding tube of handle
21
upward to cause handle grip
20
to bounce a small while sufficient distance above the top plate
15
of bezel
10
such that user may put fingers into the gap formed between handle grip
20
and bezel

, springs
164
, recessed portions
175
, recesses
165
, guide
166
, gap
166
A, and flanges
177
, F-shaped mechanism
17
is moved down to retract into bezel
10
. This can prevent user from being hurt while retracting the handle
21
. Hole
210
of the fully retracted sliding tube of handle
21
is again engaged with stud
1679
of locking device
167
. As a result, F-shaped mechanism
17
is automatically returned to a position being flush with top plate
15
of bezel
10
when hand is off the handle
21
as shown in
FIGS. 5A and 5B
.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
