Description

IN NGAOIMINT STRUCT FOR SCURTNG A CFt1TAR PRONE tATWR C1S ORTO I RARfl-CARRTn 'sLTTCt The present invention relates to an engagement structure for cellular phone leather cases, and particularly to an engagement structure for securing a cellular phone onto a hand-carried article such as a briefcase or an organizer.

A cellular phone is a commonly-used communication apparatus in a modern society. However, as sizes of cellular phones are not as small as pens which be conveniently carried, a user has to hold a cellular phone by hand all the time or put the cellular phone into a briefcase. Therefore, mobility of the user is impaired.

The present invention provides an engagement structure for cellular phone leather cases, the engagement structure includes a fixation means secured onto the cellular phone, a rivet having a shank protruding from the fixation means and an elliptical flat head defining a transverse axis and a conjugate axis, an engaging base, mounted onto a wall of the hand-carried article, having a channel, a circular recess in communication with the channel, and a slot provided under a symmetrical axis of the communicated channel and the recess, the channel having a width marginally greater than a length of the conjugate axis of the elliptical head of the rivet, the circular recess having an inner diameter marginally greater than a length of the transverse axis of the transverse axis of the elliptical head of the rivet, and the slot having a width marginally greater than a diameter of the shank of the rivet so that the rivet can be put into the channel then moved toward the circular recess to firmly engage with the base by pivotally turning the rivet within the circular recess.

In the drawings: Fig. 1 is a perspective exploded view of an engagement structure of the present invention in cooperation with an organizer; Fig. 2 is a schematic view of the engagement structure of Fig. 1; Fig. 3 is a partially cross-sectional view of the engagement structure in accordance with the present invention; Fig. 4 is a schematic view showing the engagement structure of the present invention in combination with a briefcase; Fig. 5 is a schematic view of another embodiment of the fixation means of the present invention; Fig. 6 is a schematic view of a further embodiment of the fixation means of the present invention.

Fig. 7 is a schematic view of a conventional briefcase equipped with a cellular phone leather case.

Referring now to drawings wherein like reference characters designate identical or corresponding parts through the several views. Referring to Fig. 7, a conventional briefcase 70 equipped with a cellular phone leather case 72 is illustrated. The leather case 72 has actually provided a place to install the cellular phone, however, as the leather case 72 is seamed onto a surface of the briefcase 70, the leather case 72 cannot not be suitably adapted to variable sizes of cellular phones. Thus, if a cellular phone is in size larger than the leather case, the leather case cannot be used. If the cellular phone is in size much smaller than the leather case, the cellular phone will be rocked when the briefcase is carried.

Referring to Fig 1, a cellular phone leather case 10 with an engagement structure in cooperation with an organizer 60 is shown. The cellular phone leather case 10 has a fixation pad (shown in phantom line) 12 embedded in an inner wall of the leather case 10 and a rivet 14 composed of a shank (shown in dashed line ) 15 and an elliptical head 16 defining a transverse axis and a conjugate axis.

The organizer 60 has an anchoring disc 50 embedded in a cover 62 of the organizer 60. The cover 62 is composed of a plurality of layers of sheets for increasing the strength of the cover 62. The anchoring disc 50 has a plurality of teardrop-shaped holes 52 defined therein.

A base 20, which has a plurality of engaging legs 22 each with a foot 24 protruding therefrom each leg corresponding to one of holes 52, is firmly engaged with the anchoring disc 50 by having the legs 22 pass through the holes (not shown) in the cover 62 and the holes 52 of the disc 50 and clockwise turning the disc 50. An adhesive can be used between the disc 50 and the layers of the sheets thereby tightly securing the base 20 onto the cover 62 of the organizer 60.

The base 20 further includes a rectangular channel 32 and a circular recess 34 in communication with each other. A slot 36 is provided under a symmetrical axis of the communicated rectangular channel 32 and the circular recess 34. The rectangular channel 32 has a width W marginally greater than a length of the conjugate axis of the elliptical head 16 of rivet 14, the circular recess 34 has an inner diameter D marginally greater than a length of the transverse axis of the elliptical head 16 of the rivet 14 and the slot 36 has a width marginally greater than a diameter of the shank 15 of the rivet 14 so that the rivet 14 can be put into the channel 32 and the slot 26 then moved toward the circular recess 34 to firmly engage with the base by pivotally turning the leather case 10. The channel 32 may have an enlarged opening as shown for easier inserting the rivet 14 into the channel 32.

A magnetic plate 54 is secured in a location under the anchoring disc 50 within the cover 62 of the organizer 60. An iron plate 18 is embedded within the leather case 10 in a location facing the magnetic plate 54 for increasing the stability of the cellular phone leather case 10 secured onto the organizer 60.

Referring to Fig. 2, a cellular phone leather case 10 with a cellular phone is in connection with the organizer 60.

To lock the leather case with the organizer, a user has to move the leather case 10 in a direction shown by arrow A, then pivotally turn the leather case 10 in a direction shown by arrow B an angle preferable 90 degrees. The iron plate 18 (shown in dashed line) is moved to face the magnetic plate 54 (shown in dashed line) to increase the stability of the cellular phone as previously mentioned.

As shown in Fig. 3, the legs 22 of the base 20 have been engaged with the disc 50 and the rivet 14 has been engaged with the base 20. The magnetic plate 54 is faced to the iron plate 18 in the leather case.

Referring to Fig. 4, an engagement structure of the present invention applied to a briefcase 80 (in phantom line) is shown. The arrangement of the engagement structure in Fig.

4 is analogous to the embodiment shown in Fig. 1. As shown, the base 12 engaging with the disc 50 has been secured onto a surface of the briefcase.

As shown in Fig. 5, the fixation pad 12 with the rivet 14 shown in Fig. 1 is directly adhered onto a back of a cellular phone without using a leather case.

Fig. 6 shows a top view of a fixation clip 90 in combination with a cellular phone. As shown, a rivet 14 is secured on the clip 90 for engaging with the base 20 shown in Fig. 1. Tips of the clip 90 are engaged with a plurality of slits on side walls of the cellular phone. A Velcro strip 92 is applied between a back of the cellular phone and an inner wall of the clip 90 for increasing the interconnection between the cellular phone and the clip 90.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
