Title: Crib and reversible changing table thereof

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a crib and, more particularly, to a crib equipped with a reversible changing table. Specifically, the changing table can be attached to or detached from a crib frame of the crib easily. 
     2. Description of the Prior Art 
     The structure of a current crib mainly comprises a crib frame and a cover, wherein the crib frame is used for supporting the crib and the cover is disposed on the crib frame for protection purpose. Accordingly, the crib can provide a comfortable sleeping or activity space for a baby. In general, the crib frame essentially consists of metal tubes and plastic members for connecting the metal tubes and the cover is usually made of fabric. Furthermore, in order to satisfy various requirements of consumers on the crib, there are usually a lot of additional accessories installed on the crib, such as a sleeping apparatus, a changing table, and so on. 
     However, the sleeping apparatus, which provides space for the baby to rest, and the changing table, which is used for diapering the baby, are arranged side by side on the crib frame of the current crib. The aforesaid arrangement occupies more space of the crib such that the space of the crib cannot be used efficiently. Moreover, the sleeping apparatus and the changing table are installed on the crib through other components such that the structure of the crib becomes more complicated due to the components. 
     Still further, a bracket of the changing table of the current crib is usually made of one single metal tube, i.e. the volume of the bracket is fixed. However, the volume of the bracket is usually larger than others such that the bracket of the changing table has to be packaged with much more package materials. Consequently, the volume of the bracket after package will get large and it is inconvenient for packaging and transporting the changing table. 
     SUMMARY OF THE INVENTION 
     An objective of the invention is to provide a reversible changing table installed on a crib, wherein the reversible changing table occupies less space and has simple structure. 
     Another objective of the invention is to provide a crib equipped with a reversible changing table, which occupies less space and has simple structure. 
     Another objective of the invention is to provide a reversible changing table, which can reduce package materials of a bracket of the changing table so as to package and transport the changing table more easily and conveniently. 
     According to an embodiment of the invention, a reversible changing table installed on a crib frame of a crib comprises a bracket and a pivoting mechanism. The pivoting mechanism is disposed on at least one corner of the bracket and has a locking mechanism. The bracket is installed on the crib frame through the pivoting mechanism such that the bracket is capable of being rotated with respect to the crib frame, and the locking mechanism is used for preventing the bracket from being rotated with respect to the crib frame. 
     Preferably, the bracket comprises an outer tube and an inner tube, wherein the outer tube is slidably connected to the inner tube so as to form the bracket. 
     According to another embodiment of the invention, a crib comprises a crib frame and a reversible changing table. The reversible changing table is installed on the crib frame and comprises a bracket and a pivoting mechanism. The pivoting mechanism is disposed on at least one corner of the bracket and has a locking mechanism. The bracket is installed on the crib frame through the pivoting mechanism such that the bracket is capable of being rotated with respect to the crib frame, and the locking mechanism is used for preventing the bracket from being rotated with respect to the crib frame. 
     Preferably, the bracket comprises an outer tube and an inner tube, wherein the outer tube is slidably connected to the inner tube so as to form the bracket. 
     As mentioned in the above, since the reversible changing table of the invention comprises the pivoting mechanism and the bracket, which is installed on the crib frame through the pivoting mechanism, the bracket is capable of being rotated with respect to the crib frame. Furthermore, the locking mechanism of the pivoting mechanism can be used for preventing the bracket from being rotated with respect to the crib frame. Therefore, a first surface and a second surface with different functions can be arranged on opposite sides of the bracket and the bracket can be rotated with respect to the crib frame so as to use the first surface or the second surface selectively. Accordingly, the reversible changing table of the invention occupies less space of the crib such that the space of the crib can be used efficiently. Still further, the reversible changing table of the invention has simple structure and can be used conveniently. 
     Moreover, if the bracket comprises an outer tube and an inner tube and the outer tube is slidably connected to the inner tube so as to form the bracket, the inner tube can slide into the outer tube when packaging the bracket so as to reduce the volume of the bracket and reduce package materials of the bracket. Accordingly, the changing table can be packaged and transported more easily and conveniently. 
     These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

     DETAILED DESCRIPTION 
     Please refer to the embodiments of the invention illustrated in the figures, wherein the same elements in the figures are represented by the same numerals. 
     As shown in  FIG. 1 , the crib of the invention comprises a reversible changing table  1  and a crib frame  2 . The crib frame  2  is rectangular and essentially consists of two long connecting rods  21   a  and two short connecting rods  22   a . The reversible changing table  1  is installed on middle portions of the long connecting rods  21   a  and can be rotated with respect to the crib frame  2 . The other structures of the crib frame  2  are well known by one skilled in the art and will not be depicted herein. 
     Specifically, the reversible changing table  1  comprises a bracket  10  and a pivoting mechanism which comprising two first pivoting assemblies  20 . The bracket  10  essentially consists of two long support tubes  111  and two short support tubes  112  such that the bracket  10  is also rectangular. The long support tubes  111  are corresponding to the short connecting rods  22   a  of the crib frame  2 . The first pivoting assemblies  20  are fixed on opposite corners where both ends of the long support tube  111  connect the two short support tubes  112 , respectively. Furthermore, the first pivoting assemblies  20  are fixed on middle portions of the long connecting rods  21   a . Accordingly, the bracket  10  can be rotated from one end to the other end of the crib frame  2  so as to use two different surfaces of the bracket  10  selectively. In practical applications, different covers are installed on opposite surfaces of the bracket  10  so as to form a first surface and a second surface with different functions. For example, a fabric, which is waterproof and easily cleaned, may be adapted to the first surface so as to form a changing table for diapering a baby, and another fabric, which is tender and soft, may be adapted to the second surface so as to form a sleeping apparatus for a baby to rest or nap. Accordingly, the bracket  10  can be rotated to use the changing table or the sleeping apparatus selectively and the operation is very easy for a user. It should be noted that the opposite surfaces of the bracket  10  are not limited to form the aforesaid changing table and sleeping apparatus and can be equipped with other devices based on practical applications known by one skilled in the art.

The center of the first pivoting portion  212  is pivotally connected to the first engaging socket  22  by the first pivoting member  25  and the button  23  is detachably engaged with the protruding ribs  213 . 
     As shown in  FIG. 6 , lower ends of the first engaging socket  22  curve inwardly so as to form a second fixing portion  221 . The second fixing portion  221  is engaged with the long connecting rod  21   a  of the crib frame  2 . A second pivoting portion  222  with circular shape protrudes from the second fixing portion  221  and is corresponding to the first pivoting portion  212 . An installation groove  223  is formed on and through a top end of the second pivoting portion  222 . An engaging groove  222   a , which is corresponding to the step-shaped structure  212   a  of the first pivoting portion  212 , is formed on an edge of an inner surface of the second pivoting portion  222 . To assemble the first pivoting assembly  20 , the button  23  is slidably accommodated in the installation groove  223  and protrudes from the installation groove  223 , the engaging groove  222   a  cooperates with the step-shaped structure  212   a  of the first pivoting portion  212 , the first pivoting member  25  passes through the second pivoting portion  222 , the button  23  and the first pivoting portion  212  sequentially so as to connect them together, and the button  23  is disposed in the gaps  214  between the two protruding ribs  213  of the first pivoting portion  212  such that the button  23  is slidably engaged with the protruding ribs  213  of the first pivoting portion  212 . 
     Referring to  FIGS. 5 to 8 , an upper end of the button  23  has a first protruding block  231 , a lower end of the button  23  has a second protruding block  232 , a middle portion of the button  23  has an engaging block  233 , a recess  234  is formed between the first protruding block  231  and the engaging block  233 , and a slot  235  is formed between the engaging block  233  and the second protruding block  232 . The button  23  is accommodated in the installation groove  223  of the second pivoting portion  222  and an upper end of the button  23  protrudes from the installation groove  223 .

After releasing the button  23 , the button  23  will return to the non-press position by an elastic force generated by the resilient member  24  so as to lock the first pivoting assembly  20  again. 
     As shown in  FIG. 9 , in a second embodiment of the reversible changing table  1  of the invention, the pivoting mechanism is different from that of the aforesaid first embodiment. In this embodiment, the bracket  10  is installed on the crib frame  2  through a pivoting mechanism comprising a first pivoting assembly  20  and a second pivoting assembly  30 . The first pivoting assembly  20  and the second pivoting assembly  30  are fixed on opposite ends of the long connecting rod  111  of the bracket  10 , respectively, and fixed on the crib frame  2 . In this embodiment, the structure of the bracket  10 , the structure of the first pivoting assembly  20  and the connection thereof are substantially the same as those of the aforesaid first embodiment and will not be depicted herein again. The structure of the second pivoting assembly  30  will be depicted in the following. 
     As shown in  FIG. 10 , the second pivoting assembly  30  does not comprise the locking mechanism  26  as that of the aforesaid first pivoting assembly  20  and comprises a second fixing socket  31 , a second engaging socket  32  and a second pivoting member  33 . Preferably, the second pivoting member  33  may be a rivet. However, the second pivoting member  33  may be other connecting members based on practical applications. The second fixing socket  31  is fixed on the bracket  10 , the second engaging socket  32  is fixed on the crib frame  2 , and the second fixing socket  31  is pivotally connected to the second engaging socket  32  by the second pivoting member  33 . The structures of the second fixing socket  31  and the second engaging socket  32  are substantially the same as the structures of the first fixing socket  21  and the first engaging socket  22  of the aforesaid first pivoting assembly  20  and will not be depicted herein again. Accordingly, the bracket  10  can be rotated in 180 degrees as long as the first pivoting assembly  20  is unlocked. 
     The operation and principle of the reversible changing table  1  of the invention will be depicted with  FIGS. 1 ,  11  and  12  in the following. 
     The reversible changing table  1  is installed on a middle portion of the crib frame  2  through the first and second pivoting assemblies  20  and  30 . The reversible changing table  1  is disposed on one end of the crib frame  2  so as to use one surface thereof selectively. When using the reversible changing table  1 , the first pivoting assembly  20  is locked, i.e. the button  23  protrudes from the second pivoting portion  222  of the first engaging socket  22  due to the resilient member  24 , and the engaging block  233  and the second protruding block  232  of the button  23  are engaged between the protruding ribs  213  of the first pivoting portion  212 . Accordingly, the first fixing socket  21  cannot rotate with respect to the first engaging socket  22  and the bracket  10  cannot be rotated with respect to the crib frame  2 . 
     When a user wants to use the other surface of the reversible changing table  1 , he or she can press down the button  23  by a force F in a direction indicated by an arrow shown in  FIG. 11 . When the button  23  slides downwardly, the recess  234  is aligned with the protruding ribs  213  of the first pivoting portion  212  and the second protruding block  232  is disengaged from the protruding ribs  213 . At this time, the bracket  10  can be pushed to rotate the first fixing socket  21  with respect to the first engaging socket  22 . The protruding ribs  213  are accommodated in the recess  234  during rotation of the bracket  10 . After the bracket  10  is rotated 180 degrees, the button  23  is released and returns to the non-press position by an elastic force generated by the resilient member  24  such that the engaging block  233  and the second protruding block  232  are engaged between the two protruding ribs  213  again. Consequently, the opposite surfaces of the bracket  10  can be changed with each other such that the user can use any one of the opposite surfaces with different functions of the bracket  10  selectively. The structures of the bracket  10  and the first and second pivoting assemblies  20 ,  30  are simple and the bracket  10  occupies less space of the crib frame  2  such that the space of the crib can be used efficiently. 
     Since the reversible changing table  1  of the invention comprises the first and second pivoting assemblies  20 ,  30  and the bracket  10 , which is installed on the crib frame  2  through the first and second pivoting assemblies  20 ,  30 , the bracket  10  is capable of being rotated with respect to the crib frame  2 . A first surface and a second surface with different functions can be arranged on opposite sides of the bracket  10  and the bracket  10  can be rotated with respect to the crib frame  2  so as to use the first surface or the second surface selectively. Accordingly, the reversible changing table  1  of the invention occupies less space of the crib such that the space of the crib can be used efficiently. Still further, the reversible changing table  1  of the invention has simple structure and can be used conveniently. 
     As shown in  FIGS. 13 ,  14  and  17 , in a third embodiment of the reversible changing table  1  of the invention, the reversible changing table  1  comprises a bracket  10 , a first pivoting assembly  200  and a second pivoting assembly  300 , wherein the bracket  10  can be installed on the crib frame  2  (as shown in  FIG. 1 ) through the first pivoting assembly  200  and the second pivoting assembly  300 . It should be noted that the structures and principles of the first pivoting assembly  200  and the second pivoting assembly  300  are substantially similar to the abovementioned first pivoting assembly  20  and second pivoting assembly  30 , and will not be depicted herein again. Besides, the connection and arrangement of a first fixing socket  210 , a first engaging socket  220 , a first pivoting member  250 , a button  230 , a second fixing socket  310 , a second engaging socket  320  and a second pivoting member  330  are also similar as those in the second embodiment. Still further, the abovementioned resilient member  24  can be also disposed between a bottom of the button  230  and the first engaging socket  220  and performs the same function as mentioned in the above. 
     The bracket  10  comprises an outer tube  11  and an inner tube  12 , wherein the outer tube  11  is slidably connected to the inner tube  12  so as to form the bracket  10 . When packaging the bracket  10 , the inner tube  12  can slide into the outer tube  11  so as to reduce the volume of the bracket  10 . On the other hand, when using the bracket  10  normally, the inner tube  12  can be pulled from the outer tube  11  outwardly. 
     Specifically, a first connecting end of the inner tube  12  is inserted into a second connecting end of the outer tube  11 . In this embodiment, the outer tube  11  is U-shaped and the inner tube  12  is reversed U-shaped such that the outer tube  11  and the inner tube  12  can be connected to each other so as to form the bracket  10 . An external diameter of the inner tube  12  is smaller than an internal diameter of the outer tube  11  such that an open side of the inner tube  12  (i.e. both ends of the inner tube  12  due to the reversed U-shape) can be inserted into an open side of the outer tube  11  (i.e. both ends of the outer tube  11  due to the U-shape) and the outer tube  11  and the inner tube  12  can slide with respect to each other. 
     Preferably, as shown in  FIGS. 15 and 16 , the first connecting end of the inner tube  12  has an engaging portion  3 , an engaging hole  4  is formed on the second connecting end of the outer tube  11 , and the inner tube  12  can be locked with the outer tube  11  by engaging the engaging portion  3  and the engaging hole  4 . When the engaging portion  3  is engaged into the engaging hole  4 , the outer tube  11  and the inner tube  12  are locked and cannot slide with respect to each other, i.e. the outer tube  11  and the inner tube  12  are connected to each other fixedly. When the engaging portion  3  is disengaged from the engaging hole  4 , the outer tube  11  and the inner tube  12  are unlocked and can slide with respect to each other. At this time, the outer tube  11  and the inner tube  12  are slidably connected to each other. That is to say, the inner tube  12  can slide into the outer tube  11  so as to reduce the volume of the bracket  10 . 
     For further description, a connecting member  5  is fixed on the second connecting end of the outer tube  11  and comprises a sleeve portion  51 , a press portion  52  and a positioning portion  53 , wherein the sleeve portion  51  is fixed on an inner wall of the outer tube  11 , the inner tube  12  can be inserted into the sleeve portion  51 , the press portion  52  is used for pressing the engaging portion  3  so as to disengage the engaging portion  3  from the engaging hole  4 , and the positioning portion  53  is used for fixing the connecting member  5  on the outer tube  11 . A spring plate  6  is disposed in the first connecting end of the inner tube  12 , the engaging portion  3  is located at one end of the spring plate  6  and protrudes from the inner tube  12 , and the engaging portion  3  is engaged into the engaging hole  4  by an elastic force generated by the spring plate  6 . When the press portion  52  is pressed to disengage the engaging portion  3  form the engaging hole  4 , the inner tube  12  can slide into the outer tube  11  rightward, as shown in  FIG. 16 . When a user wants to use the reversible changing table  1 , he or she can pull the inner tube  12  out from the outer tube  11  leftward and the engaging portion  3  will be engaged into the engaging hole  4  again by the elastic force generated by the spring plate  6 . Consequently, the outer tube  11  and the inner tube  12  are locked again. In this embodiment, the press portion  52  is disposed on the connecting member  5  through an arc bridge. When the press portion  52  is situated in a free state, the press portion  52  is located above the engaging hole  4 . When the press portion  52  is pressed, the press portion  52  can go into the engaging hole  4 . When the press portion  52  is released, the press portion  52  returns to the free state due to an elastic force generated by the arc bridge. The positioning portion  53  may be, but not limited to, a resilient buckle passing through the outer tube  11  and engaged with the outer tube  11 . 
     Preferably, as shown in  FIGS. 18 to 20 , the inner tube  12  comprises two transition tubes  121  and a connecting tube  122 , the connecting tube  122  is connected between the two transition tubes  121 , and each of the transition tubes  121  is slidably connected to the outer tube  11 . In this embodiment, both ends of the connecting tube  122  are inserted into the two transition tubes  121 , respectively, and are fixed by spring plates (not shown) so as to assemble or disassemble the inner tube  12 . However, the invention is not limited to the aforesaid embodiments and the connecting tube  122  may be fixed to the transition tubes  121  by screws or rivets. 
     Preferably, the reversible changing table  1  of the invention may further comprise an engaging member  8  fixed on the inner tube  12 . A first connecting portion  71  protrudes from the second pivoting assembly  300  (as shown in  FIGS. 19 and 20 ) and the engaging member  8  has a second connecting portion  82 . The inner tube  12  can be connected to the second pivoting assembly  300  by connecting the first connecting portion  71  and the second connecting portion  82 . It should be noted that the first pivoting assembly  200  may also have the first connecting portion  71  for connecting the engaging member  8  and the inner tube  12 . One of the first connecting portion  71  and the second connecting portion  82  may be an engaging hook and the other one of the first connecting portion  71  and the second connecting portion  82  may be an engaging groove. In this embodiment, the first connecting portion  71  is an engaging hook and the second connecting portion  82  is an engaging groove. 
     Specifically, the engaging member  8  has a sleeve portion  81  and the inner tube  12  can be inserted and fixed into the sleeve portion  81 . The second connecting portion  82 , which can be engaged with or disengaged from the first connecting portion  71 , is formed outside the sleeve portion  81 . The first connecting portion  71  can be operated to be engaged with or disengaged from the second connecting portion  82  so as to engage the engaging member  8  with the first and second pivoting assemblies  200 ,  300  or disengage the engaging member  8  from the first and second pivoting assemblies  200 ,  300 . When the first connecting portion  71  is engaged with the second connecting portion  82  of the engaging member  8 , the engaging member  8  is engaged with the first and second pivoting assemblies  200 ,  300  accordingly. When the first connecting portion  71  is disengaged from the second connecting portion  82  of the engaging member  8 , the engaging member  8  is disengaged from the first and second pivoting assemblies  200 ,  300  accordingly so that the engaging member  8  can be detached from the first and second pivoting assemblies  200 ,  300 . Consequently, the inner tube  12  can be detached from the first and second pivoting assemblies  200 ,  300  such that the bracket  10  can be detached from the first and second pivoting assemblies  200 ,  300 . In this way, the crib and the reversible changing table thereof can be packaged and transported more conveniently. 
     In this embodiment, the bracket  10  is rectangular as well as the crib frame  2  such that the outer tube  11  and the inner tube  12  can slide with respect to each other more smoothly. However, the bracket  10  may be formed as other shapes except rectangular in another embodiment. 
     The structure and arrangement of the reversible changing table  1  of the invention may be also used in other child devices based on practical applications except the crib. 
     The structure and arrangement of the crib frame  2  of the invention are well known by one skilled in the art and will not be depicted herein. 
     Compared to the prior art, since the reversible changing table of the invention comprises the pivoting mechanism and the bracket, which is installed on the crib frame through the pivoting mechanism, the bracket is capable of being rotated with respect to the crib frame. Furthermore, the locking mechanism of the pivoting mechanism can be used for preventing the bracket from being rotated with respect to the crib frame. Therefore, a first surface and a second surface with different functions can be arranged on opposite sides of the bracket and the bracket can be rotated with respect to the crib frame so as to use the first surface or the second surface selectively. Accordingly, the reversible changing table of the invention occupies less space of the crib such that the space of the crib can be used efficiently. Still further, the reversible changing table of the invention has simple structure and can be used conveniently. 
     Moreover, if the bracket comprises an outer tube and an inner tube and the outer tube is slidably connected to the inner tube so as to form the bracket, the inner tube can slide into the outer tube when packaging the bracket so as to reduce the volume of the bracket and reduce package materials of the bracket. Accordingly, the changing table can be packaged and transported more easily and conveniently. 
     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
