Description
BACKGROUND OF THE INVENTION
The present invention relates to a miniature portable radio equipment.
DESCRIPTION OF RELATED ART
A miniature portable radio equipment of a certain kind incorporates therein ROM in which ID code is written upon delivery or use. Further, there have been known many kinds of arrangements, that is, in the device as shown in Fig. 5, write-in terminals laid on the bottom part of a housing 51, are covered with a battery lid 53, and in an arrangement shown in Fig. 6, write-in terminals (which are not shown) are disposed inward of a hole 63 which is formed in the bottom part of a housing 61, adjacent to a battery lid 62. Further, there has been known a portable radio equipment having a clip (which is not shown) which is attached to the rear surface of a housing and which is adapted to hook on a belt and a pocket of clothes worn by a person so as to prevent a portable radio equipment from loosing or falling.
Such write-in terminals are important components of the radio equipment, and accordingly, has to be protected. However, in the above-mentioned conventional radio equipment, as shown in Fig. 5, the battery lid 53 is removed each time when a battery is replaced. Thus, the write-in terminals 52 are exposed to the exterior each time when the battery lid 53 is opened, and accordingly, it can be easily touched by a human finger or the like. Therefore, it is not preferable. Further, with the conventional arrangement shown in Fig. 6, since the write-in terminals are always exposed to the inside of the hole 63, they are possibly affected by the external circumstances, and therefore, it is unfavorable.
Meanwhile, in order to carry the portable radio equipment, it is not only attached to a belt or a pocket of clothes with the use of the clip, but it is held in a handbag or a pocket without using the clip, particularly in such a case that the portable radio equipment is used by a woian. In the latter case, the clip is not only necessary but becomes hampering. Further, in order to enable the portable radio equipment to be used in both ways, that is, with and without the clip, two housings with a clip and without a clip, should be prepared, it cause the cost thereof to rise up.
BRIEF SUMMARY OF THE INVENTION
The present invention is devised in view of the above-mentioned problem inherent to the conventional portable radio equipment, and accordingly, one object of the present invention is to provide a portable radio equipment which can protect write-in terminals from being touched by a human finger or against the external environment, that is, it is possible to prevent useless writing.
The other object of the present invention is to provide a portable radio equipment which can be hooked on a belt or a pocket of clothes worn by a person with the use of a clip which can be removed when the portable radio equipment is held in a handbag or a pocket, thereby it is possible to aim at reducing the cost thereof.
Further, the other object of the present invention is to provide a portable radio equipment which prevents the clip from being unexpectedly removed, that is, the clip can be surely locked onto the housing.
To the end, according to a first aspect of the present invention, there is provided a portable radio equipment comprising a housing in which an electronic circuit and a battery are disposed, a fitting groove formed in the housing; a clip and an exchange panel which are selectively fitted in the fitting groove, engaging means provided on both side edges of the clip and the exchange panel, for slidably engaging the clip and the exchange panel in the fitting groove; a locking means adapted to releasably lock the clip and the exchange panel in the fitting groove, and write-in terminals laid on the bottom part of the fitting groove.
According to a second aspect of the present invention, in addition to the first aspect of the present invention, locking projections for releasing the locking means are formed on the rear surface of each of the clip and the exchange panel.
According to a third aspect of the present invention, in addition to the first and second aspects of the present invention, the clip and the exchange panel adapted to be selectively fitted in the fitting groove, are locked by a battery lid which is rotatably attached and releasably locked to the housing.
With this arrangement, according to the present invention, since the clip is fitted in the fitting groove in the housing by the engaging means and is locked therein by the locking means, the portable radio equipment can be held being hooked on a belt or a pocket of clothes worn by a person. Meanwhile, since the exchange panel can be fitted in the fitting groove, instead of the clip, and since it is locked in the fitting groove by the locking means, the portable radio equipment can be held in a handbag or a pocket without the clip which is hampering in this case. Further, since the write-in terminals are laid in the bottom part of the fitting groove, and since the clip or the exchange panel is locked in the fitting groove, the write-in terminals can be surely shielded.
Further, the clip and the exchange panel can be removed smpothly by use of a special unlocking tool which is inserted in a gap on the rear surface side of the clip or the exchange panel so as to release the locking means.
Further, since the clip or the exchange panel is fitted and locked in the fitting groove in the housing, and is further locked by the battery lid which is also locked to the housing, the clip and the exchange panel can be held in the housing with a high degree of reliability.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 to 3, a fitting groove 2 is formed in the center part of the rear surface of a housing 1, and is formed on its both longitudinal side walls with engaging grooves 3. The fitting groove 2 is opened at one end part of the housing 1 so as to define an opening through which a clip 17 or an exchange panel 18 which will be explained later can be introduced into the fitting groove 2. The bottom part of the fitting groove 2 is deeply cut so as to form a recess in the vicinity of the opening of the groove 2, and a locking hole 4 is formed on the bottom of the groove 2 within the recess. A battery lid 6 which is adapted to open and close a battery storage chamber 5 and the opening of the fitting groove 2 is attached to the one end part of the housing 1.More specifically, one side part of the one end part of the housing 1 is formed therein with a cutout 8 which defines therein a journal section having first and second journal parts 9, 10 which are opposed to each other through a space 11 within the journal section. The space 11 is narrower than the journal parts 11 since a partition projection wall 12 is formed therein. This partition projection wall 12 is formed therein with slits 13 which give a resiliency so that the partition projection wall 12 can be resiliently retracted. A shaft part 14 formed on the proximal end part of the battery lid 6 is rotatably supported by the first journal part 9 and can be displaced between the first and second journal parts 9, 10 by way of the space 11 while the partition projection wall 12 being forced to be retracted.An engaging protrusion 15 is formed at the inner side of the free end part of the battery lid 6, and an engaging cutout 16 is formed in the one end part of the housing 1 on the side remote from the cutout 8. Accordingly, when the battery lid 6 is pushed after being closed so that the shaft 4 is displaced from the journal part 9 to the journal part 10, the engaging protrusion 15 is fitted in the engaging cutout 16 so as to firmly lock the battery lid 6.
A clip 17 and an exchange panel 18 can be selectively fitted in the above-mentioned fitting groove 2. The clip 17 has a clip member 20 having a hook-like part at its distal end and rotatably journalled at its proximal end to one short side part of a base plate 19 by means of a shaft 21, and the distal end part of the clip member 20 is urged against the base plate 19 by a coil spring (which is not shown) and is therefore made into close contact with the latter. Accordingly, the clip member 20 can be rotated about the shaft 21, overcoming the resilient force of the coil spring so as to be displaced away from the base plate 19. A locking projection 22 is formed integrally with the rear surface of the base plate 19 at a position corresponding to that of the locking hole 4, in the distal end part of the clip member 20.Further, low height releasing protrusions 23 are formed integrally with the rear surface of the base plate 19 on both sides of the locking projection 22. The base plate 19 has engaging ridges 24 adapted to be engaged in the engaging grooves 3, and integrally formed on both long side faces of the base plate 19.
These engaging ridges 24 are cut intermediately so that they do not reach positions rear the locking projection 22. It is noted here that the dimensions of the ridges and the grooves 3 are so selected that the locking projection 22 side part of the base plate 19 can be elastically deformed so as to be curved with the ridges 24 being engaged in the grooves 3 (Refer to Fig. 3b).
The exchange panel 18 is also adapted to be fitted in the fitting groove 2, being flush substantially with the rear surface of the base plate 19, and is integrally formed thereon with a locking projection 25 and releasing protrusions 26 similar respectively to the locking projections 22 and the releasing protrusions 23, on one short side part thereof. Further, engaging ridges 27 similar to the engaging ridges 24 of the clip 17 are also formed integrally with the long side faces of the exchange panel 18.
Further, write-in terminals 28 through which
ID codes are written in ROM is laid on the bottom part of the fitting groove 2. That is, the write-in terminals formed on a print circuit board 30 are disposed in a hole 29 formed in the bottom part of the grove 2 so that they are exposed to the outside through the hole 29.
The locking projection 22 or 25 of the clip 17 or the exchange panel 18 are released from the locking hole 4 in the housing 1 by use of a releasing tool 31 which is clearly shown in Fig. 9, having engaging protrusions 32 at its front end part, made of resilient materials and bent in a V-like shape.
Referring to Figs. 3a and 3b together with
Figs. 8 and 9, explanation will be made of the use mode of the portable radio equipment.
In the case of use of the portable radio equipment attached on a belt or a pocket of clothes worn by the user, after the battery lid 6 being opened, the engaging ridges 24 of the base plate 19 are fitted in the engaging grooves- 3 through the opening of the fitting groove 2, and is then slid along the grooves 3 in the direction of the arrow A until the clip 17 is fully fitted in the fitting groove 2. Since the ridges 24 are not completely extended to positions near to the locking projection 22, the locking projection 22 can override the end part of the housing 1 due to an elastic deformation of the base plate 19 on the projection 22 side thereof. That is, as clearly shown in Fig. 3a, the projectipn 22 is adapted to be engaged into the locking hole 4.With this arrangement, the base plate 19 of the clip 17 fitted in the fitting groove 2 can be locked so that the write-in terminals can be covered or shielded. Thereafter, as shown in Fig. 2a, the battery lid 6 is turned in the direction of the arrow B about the shaft 14 supported on the first journal part 9, and is then pushed in the direction of the arrow C as shown in Fig. 2b. On the way of this placement through the space 11 from the first journal part 9 to the second journal part 10, a click feeling can be given by the partition projection wall 12, and is then supported by the second journal part 10. Meanwhile, the engaging protrusion 15 is engaged and locked in the engaging cutout 16.The locked battery lid 6 abuts against the end face of the distal end part of the clip member 20 on the base plate 19 of the clip 17 so as to limit the displacement of the clip 17, and accordingly, the clip 17 is surely locked. Accordingly, the portable radio equipment can be attached to the belt or the pocket by means of the clip member 20.
Meanwhile, in the case of the portable radio equipment being held in a handbag, a pocket of clothes or the like,'at first the battery lid 6 is pulled in the direction reverse to the direction of the arrow C, and then the shaft 14 supported by the second journal part 10 is shifted through the space 11 to the first journal part 9 while deforming the partition projection wall 12 and is then held thereby. Accordingly, the engaging protrusion 15 is disengaged from the engaging cutout 16 so that the battery lid 6 is released. Then, the battery lid 6 is turned about the shaft 14 in the direction reverse to the direction of the arrow B as shown in Figs. 1 or Fig. 2a. Further, when the forward end part of the releasing tool 31 is inserted between the bottom part of the opening of the fitting groove 2 and the releasing protrusions 23 by use of a resilient deformation of the engaging projection 23, the locking protrusion 22 side of the base plate 19 of the clip 17 is elastically deformed and curved due to the repulsive resiliency of the locking parts 32. Accordingly, the locking projection 22 is disengaged from the locking hole 4, that is, the clip 17 is released. In this condition, since the front end parts of the locking parts 32 are engaged with the inside of the releasing protrusions 23, if the releasing tool 31 is pulled out, the engaging ridges 24 of the clip 17 are slid along the engaging grooves 3 in the housing 1, and accordingly, the clip 17 is removed from the fitting groove 12.
Then, the exchange panel 18 is fitted in the fitting groove 2, similar to the installation of the clip 7.
More specifically, the engaging ridges 27 of the exchange panel 18 are inserted in the engaging grooves 3 in the housing 1 through the opening of the fitting groove 12, and then the engaging ridges are slid along the engaging grooves 3 in the housing 1 until the exchange panel 18 is fully fitted in the fitting groove 12. Since the engaging ridges do not reach positions near to the locking protrusion 25, the locking protrusion 25 can override the end part of the housing 1 and then engages into the locking hole 4 as shown in Fig. 3a. Accordingly, the exchange panel 8 can be fitted and locked in the fitting groove 2, and further, the write-in terminals can be shielded. Thereafter, the battery lid 6 is turned in the direction of the arrow B as shown in Fig. 2a, and is then shifted in the direction of the arrow C in order to be locked.Thus, the exchange panel 8 can be surely locked, as mentioned above. Accordingly, the clip 7 which becomes obstructive when the portable radio equipment is stored in a handbag or a pocket can be removed.
The removal of the exchange panel 18 from the housing 1 can be made, similar to that of the clip 17, and accordingly, the explanation thereof is omitted.
Further, in order to write ID codes in the
ROM, as shown in Fig. 4, the clip 17 or the exchange panel 18 is removed from the fitting groove 2 in the housing 1 so as to expose the write-in terminals 28 to the outside through the hole 29, and the write-in terminals 28 are connected thereto with contact terminals 34 connected with a writing device 33 which is then manipulated so as to write the ID codes into the ROM.
Since the clip 7 or the exchange panel 18 can be held in the fitting groove 12 in the housing 1 under locking condition when the battery lid 6 is opened so as to replace batteries, there is no risk of missing of the clip 7 or the exchange panel 18. Further, since the clip 7 or the exchange panel 18 can be removed only by use of the special releasing tool 31, it is difficult for third party to remove the clip 7 or the exchange panel 18.
Although the embodiment of the present invention has been detailed, the present invention should not be limited to this embodiment, but can be changed or modified therefrom within the spirit and the scope of the invention which can be only limited by the appended claims.
For example, the engaging grooves 3 can be formed in the base plate 19 of the clip 17 or the exchange panel 8 while the engaging ridges 24, 27 can be formed on the side walls of the fitting groove 2 in the housing 1.
Further, in order to further ensure the locking of the clip 17 or the exchange panel 18 in the fitting groove 2 in the housing 1, it is preferable to use a battery lid locking mechanism as shown in Figs. 10a to 10c. That is, a latch plate 35 is slidably fitted in a shallow groove 36 formed in the side surface of the housing 1 on the side where the distal end face of the battery lid 6 is positioned when the latter is closed.
Further, the distal end face of the lid is formed therein with a shallow groove 37 which is aligned with the shallow groove 36 when the lid 6 is closed.
When the lid 6 is closed, the latch plate 35 is shifted toward the distal end part of the lid 6 so as to be extended between both grooves 36, 37, and accordingly, the lid 6 is firmly locked. Accordingly, this can, in turn, firmly lock the clip 17 or the exchange panel 18 fitted in the fitting groove 12.
The latch plate 35 and the shallow groove 36 are clearly shown in Fig. 7. Engaging ridges 35a formed on both side surfaces of the base of the latch plate 35 are engaged slidably in engaging grooves 36a formed in the side walls of the shallow groove 36. When the latch plate 35 is fitted in the shallow groove 36, a cutout 35c formed in the base 35b of the latch plate 35 receives a raised part 36c formed on the bottom surface of the shallow groove 36 while recessed parts formed in both side surfaces of the base being fitted onto protrusions 36b formed on the side walls of the shallow groove 36. With this arrangement, the latch plate 35 can be prevented from coming off.
