DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1A, 1B, 2 and 3, the present invention provides a carrying device, including a housing 1 and two fastening devices 2. The housing 1 is used to carry goods such as speakers or lamps and install and fix the goods on a ceiling. The two fastening devices 2 are respectively disposed on two sides of the housing 1.


Each of the fastening devices 2 has a base 21, a fastening piece 22, a clamping piece 23, an elastic piece 24 and a bolt 25. The base 21 has a bottom wall 211, two lateral walls 212, an accommodating space 213 and two supporting portions 214. The two lateral walls 212 are symmetrically disposed on two sides of the bottom wall 211. Each of the lateral walls 212 has a pivot hole 2121 and a positioning groove 2122. The two lateral walls 212 are essentially perpendicular to the bottom wall 211. The bottom wall 211 and the two lateral walls 212 define the accommodating space 213 for containing the fastening piece 22 and the elastic piece 24. The two lateral walls 212 respectively and outwardly extend to form one of the two supporting portions 214. The two supporting portions 214 are respectively disposed on the two sides of the housing 1, so that the two supporting portions 214 are used to support and carry the housing 1 and the goods carried by the housing 1.


The fastening piece 22 is received in the accommodating space 213. Two ends of the fastening piece 22 are respectively put in the positioning grooves 2122 of the two lateral walls 212 and the fastening piece 22 is rotatably disposed on the base 21. The fastening piece 22 has a fastening portion 221 and two braking portions 222. Two ends of the fastening portion 221 respectively extend to form one of the two braking portions 222. The two braking portions 222 are integrally formed with the fastening portion 221. When the two braking portions 222 rotate relative to the base 21, the two braking portions 222 drive the fastening portion 221 to be rotated, so that the fastening portion 221 reversely protrudes from the bottom wall 211. For example, but not limited to, the fastening portion 221 rotates from a position which is parallel to the bottom wall 211 to another position which is perpendicular to the bottom wall 211. Thus, the fastening piece 22 may rotate between a released position (as shown in FIG. 3) and a fastening position (as shown in FIGS. 4 and 5).


The clamping piece 23 has an abutting portion 231, a jamming portion 232 and two pivoted portions 233. One end of the clamping piece 23 is pivoted on the base 21 and the other end of the clamping piece 23 slantly is extended to form the abutting portion 231. The abutting portion 231 and the two supporting portions 214 jointly constitute a stable structure (as shown in FIG. 3).


Two sides of the one end of the clamping piece 23 respectively extend to form the two pivoted portions 233 for pivoting the clamping piece 23 on the base 21, so that the clamping piece 23 can swing relative to the base 21. One face of the clamping piece 23 is provided with the jamming portion 232. The configuration of the jamming portion 232 correspondingly arranges to the configuration of the fastening portion 221, so that the jamming portion 232 of the clamping piece 23 can selectively fasten the fastening portion 221 of the fastening piece 22 (as shown in FIG. 5) and the two braking portions 222 are disposed on the base 21 in a manner like a cantilever beam. For example, but not limited to, the jamming portion 232 is a hook and the fastening portion 221 is a circular rod, so that the jamming portion 232 fastens the fastening portion 221 by combining the hook and the circular rod.


The elastic piece 24 is disposed between the base 21 and the clamping piece 23 and is received in the accommodating space 213. One end of the elastic piece 24 abuts against the base 21 and the other end of the elastic piece 24 abuts against the clamping piece 23. When the clamping piece 23 swings relative to the base 21, the elastic piece 24 disposed between the base 21 and the clamping piece 23 produces elastic restoring forces acting on the clamping piece 23. For example, the clamping piece 23 swings toward the base 21 via a rotation shaft such as the bolt 25 (as shown in FIG. 4), the elastic piece 24 is deformed and produces the elastic restoring forces. However, the elastic piece 24 of the present invention includes but is not limited to a torsion spring. The elastic piece 24 also can be a tension spring, a compression spring, a winding spring or an improved spring which has laid-open or been used.


The bolt 25 penetrates through the pivot holes 2121 of the two lateral walls 212 of the base 21, the two pivoted portions 233 of the clamping piece 23, and the elastic piece 24, so that the elastic piece 24 sleeves around the bolt 25. Otherwise, the number of the fastening devices 2 may be three, four, or more than four. Those fastening devices 2 are spacedly disposed on a periphery of the housing for stably carrying the housing 1 and the goods carried by the housing 1.


Because of an improvement of the fastening devices 2 of the present invention, the housing 1 can be easily and rapidly installed on the ceiling 3 and can be easily and rapidly dislodge from the ceiling 3 for increasing the convenience of installation and for saving the time of installation. Referring to FIGS. 6A to 6C, the clamping piece 23 firstly swings toward the base 21, and then the jamming portion 232 fastens the fastening portion 221 for fastening the clamping piece 23 onto the base 21 such that the fastening piece 22 can be located on the fastening position and the base 21 can be covered with the clamping piece 23 (as shown in FIG. 6A). The two braking portions 222 disposed on the base 21 are rotated and disposed on the base 21 in a manner like a cantilever beam.


To follow, the users push the housing 1 and the two fastening devices 2 into an installation hole 31 of the ceiling 3 (as shown in FIG. 6B). The two braking portions 222 are swung downwardly by colliding with the ceiling 3 (as shown in 6C) and the two braking portions 222 drive the fastening portion 221 to be rotated such that the fastening portion 221 is parallel to the bottom wall 211 of the base 21 and the clamping piece 23 is resorted to original position, so that the abutting portion 231 abuts against the ceiling 3. Thus, the fastening piece 22 can be located on the released position and the clamping piece 23 is opened from the base 21.


For installing, the abutting portion 231 of the clamping piece 23 can automatically abut against the ceiling 3 due to the fastening piece 22 collides with the ceiling 3. The two supporting portions 214 of the base 21 are fixed on the housing 1 for supporting and carrying the housing 1 and the goods carried by the housing 1. The abutting portion 231 of the clamping piece 23 is used to abut and compress the ceiling 3, so that the housing 1 and the abutting portion 231 jointly clamp the ceiling 3 such that the housing 1, the two supporting portions 214, the abutting portion 231 and the ceiling 3 constitute a stable structure for installing and fixing the housing 1 on the ceiling 3.


In conclusion, the present invention has following advantages:

  • 1. In order to the housing 1 can be easily and rapidly installed on the ceiling 3 and can be easily and rapidly dislodge from the ceiling 3 for increasing the convenience of installation and for saving the time of installation, the abutting portion 231 of the clamping piece 23 can automatically abut against the ceiling 3 due to the fastening piece 22 collides with the ceiling 3.
  • 2. The two supporting portions 214, the abutting portion 231 and the ceiling 3 constitute a stable structure for installing and fixing the housing 1 on the ceiling 3.
