ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a mechanism for removably engaging an item of portable equipment such as a transceiver or the like with a belt clip installed on either a band or a belt.
2. Description of the Prior Art
The rapid progress or advancement in a semiconductor manufacturing technology in recent years has caused a remarkable small-sized formation of portable wireless machines such as a transceiver or various kinds of measuring equipment, and this progress has further caused a portable system with a belt clip to be widely used.
That is, these types of portable equipment are most conveniently installed at either a waist part or a belly part of a person with belt clip due to the fact that their size or weight is too large or heavy for being stored in a pocket in its-non-used state, or when they are put in a bag or the like, they are inconveniently taken out and used every time they are needed.
Then, with this kind of belt clip, there are provided one system in which the belt clip is directly fixed to either a casing surface of a portable equipment or its protection cover in advance and the other system in which a convenient engaging part arranged independently at the portable equipment is engaged with the belt clip.
In the former system, since the entire belt clip is integrally assembled with the portable equipment, there occurs a certain disadvantage in convenience of use at the time of utilization of the portable equipment, and further since the belt clip is installed at the belt with its clip side holding either the band or the belt, an inconvenience state created in which smooth fitting or removing cannot be carried out.
In turn, in the case of latter system, the portable equipment is merely provided with a convenient and small engaging part, a mechanism that can be easily fitted or disengaged between the engaging part and the belt clip can be independently constituted, so that such disadvantage and inconvenience in operation are not produced.
In the case of the engaging mechanism in which the belt clip and the portable equipment are installed independently, it is required to perform an easy engaging or disengaging operation and the belt clip is not easily removed under vibration and the like.
Accordingly, although various kinds of mechanisms have been proposed as the aforesaid engaging mechanism, the system having the configuration shown in
FIGS. 10
to
13
is shown as one example.
At first,
FIG. 10
shows a mechanism applied at the portable equipment, where (A) is a substantial front elevational view for showing the portable equipment; (B) is a sectional view taken along an arrow line Y—Y in (A); and (C) is a sectional view taken along an arrow line X—X in (A).
In this figure,
101
denotes a portable equipment,
102
denotes a protrusion fixed with a screw at a rear surface of a casing of the portable equipment
101
, where the protrusion
102
is comprised of a base
103
corresponding to a fixing plate, a cylindrical short column
104
and a flange
105
.
In addition, the flange
105
is comprised of a disc
106
and an annular frame
107
formed around the circumferential edge of the disc, where the annular frame
107
is formed with a discontinuous segment
108
at its upper part.
In turn,
FIG. 11
shows a mechanism at the belt clip, where (A) is a left side elevational view for showing the belt clip; (B) is a front elevational view; (C) is a sectional view taken along an arrow line Y—Y in (B); and (D) is a sectional end view taken along an arrow line X—X in (B).
In this figure,
201
denotes a belt clip,
202
denotes a clip and
203
denotes an engaging plate for engaging with the portable equipment
101
.
In this figure, the clip
202
and the engaging plate
203
are integrally formed with bearing plates
204
and
205
at both sides near their upper positions of their opposing faces, wherein both bearing plates
204
,
205
are rotatably connected at a shaft
206
under a state in which both bearing plates
205
at the engaging plate
203
fit both bearing plates
204
of the clip
202
inside.
Then, a twisted coil spring
207
is fitted outside between both bearing plates
204
at the shaft
206
, both arms of the twisted coil spring
207
press and bias against each of the inner surface of the clip
202
and the inner surface of the engaging plate
203
.
In addition, the lower end of the clip
202
is integrally formed with an L-shaped hook
208
facing inside, and a biasing force attained by both arms of the twisted coil spring
207
pushes the extremity end of the hook
208
against the engaging plate
203
under a principle of lever with the shaft
206
being applied as a fulcrum.
Accordingly, although each of the plate surfaces of the clip
202
and the engaging plate
203
is normally in a parallel state to each other, when the upper sides of the clip
202
and the engaging plate
203
are held with fingers to cause them to be approached to each other, the extremity end of the clip
202
is opened, resulting in that a belt is received between it and the engaging plate
203
under this opened state and after this operation, when the holding pressure by the fingers is released, the belt clip
201
can be installed at the belt.
The front surface of the engaging plate
203
is formed with a small-protrusion type claw
209
and an engaging part
210
.
In this case, the claw
209
has such a shape as one in which a width (w) of the claw
209
is narrower than a width of the discontinuous segment
108
of the annular frame
107
formed at the flange
105
of the portable equipment
101
, a length (a) of the claw
209
is smaller than an inner diameter of the annular frame
107
, and a height (h) of the claw is set to be lower than a height of the annular frame
107
, wherein the claw is formed at the central position of the lower region of the engaging plate
203
.
In addition, the engaging part
210
is comprised of frames
211
,
212
arranged at both sides and a front plate
214
formed with a substantial U-shaped recess
213
, and this is constituted as a cylindrical member at the surface of the engaging plate
203
.
In such a configuration comprised of the protrusion
102
at the portable equipment
101
and the engaging plate
203
at the belt clip
201
, when the portable equipment
101
is set upside down (the discontinuous segment
108
of the annular frame
107
at the protrusion
102
being set at a lower side) and its flange
105
is fitted into the engaging part
210
at the belt clip
201
under a state in which the belt clip
201
is being installed at the belt
220
, as shown in
FIG. 12
, the flange
105
is guided down to the lower side of the engaging part
210
while the short column part
104
of the protrusion
102
is being guided by the recess
213
.
Then, the discontinuous segment
108
at the annular frame
107
of the portable equipment
101
causes the entire claw
209
at the belt clip
201
to be inserted into the annular frame
107
and then the short column
104
at the portable equipment
101
under this state is engaged with the lower-most part of the recess
213
of the belt clip
201
.
Then, as shown in
FIG. 13
, when the portable equipment
101
is turned from the aforesaid state by 180°, the annular frame
107
at the flange
105
is naturally turned around the claw
209
at the belt clip
201
, and the discontinuous segment
108
is positioned at the upper side of the claw
209
.
Accordingly, the lower side of the annular frame
107
of the flange
105
at the portable equipment
101
is engaged with the claw
209
at the belt clip
201
, its short column
104
is restricted under a diagonal relation where it can be moved upward only by the recess
213
at the belt clip
201
, resulting in that the portable equipment
101
becomes positioned such that the belt clip
201
can be removed only after the portable equipment
101
is turned again by 180°.
That is, the portable equipment
101
is engaged with the belt clip
201
under a locked state where a removal stopp
