Abstract:
A connection assembly for offsetting tilting caused by weight difference between two objects includes a first male connector, a second male connector linearly misaligned with the first male connector, a first female connector and a second female connector linearly misaligned with the first female connector. Both the first and second male connectors are formed on a first object and both the first and second female connectors are formed on a second object. Due to the misaligned relationship, weight of the combination between the first object and the second object is redistributed to avoid tilting.

BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a connection assembly, and more particularly to a connection assembly for offsetting tilting situation especially when two objects of unbalanced weights are to be combined. 
   2. Description of the Prior Art 
   A conventional connection assembly for connecting two objects together includes two extensions formed on one object and two indentations corresponding to the two extensions and formed on the other object. When combination of these two objects is required, the two extensions are extended into the two indentations to complete the combination of these two objects. However, if the two objects are each of a different weight, the combination of these two objects will cause a tilting effect after the completion of the combination. That is, after the combination, the center of gravity of the combination is tilted toward the heavy one. When transportation of the combination is required, the connection assembly is easily broken due to the unbalanced weight distribution. 
   A perfect example of this connection assembly can be understood in the connection between a UPS (uninterrupted power supply) and an appliance in associated with the UPS. As is well known in the art, the weight of the UPS is usually much heavier than that of the appliance such that after the UPS is connected to the appliance, the overall weight of the combination is mostly focused on the UPS, which causes a tilting effect to the combination. Therefore, when the combination is to be transported, the worker has to be extra careful in handling the combination. Otherwise, the combination of the UPS and the appliance is easily damaged and the connection therebetween is easily broken. 
   To overcome these shortcomings, the present invention tends to provide an improved connection assembly to mitigate the aforementioned problems. 
   SUMMARY OF THE INVENTION 
   The primary objective of the present invention is to provide an improved connection assembly having a pair of male connectors adapted to be formed on a first object and a pair of female connectors adapted to be formed on a second object and corresponding to the pair of male connectors so that after the pair of male connectors is extended into the pair of female connectors, the first object and the second object are securely connected with each other. Each of the pair of male connectors adapted to be formed on the first object is offset to each other and each of the pair of female connectors adapted to be formed on the second object is also offset to each other so that the connection between the first object and the second object shifts part of the overall weight of the combination of the first object and the second object to accomplish balance purpose. 
   In order to accomplish the aforementioned objective, the connection assembly of the present invention includes a first male connector, a first cutout adapted to be formed on a side face of the first object and a second male connector extending from a side face defining the first cutout so that the first male connector and the second male connector are zigzag to one another. The connection assembly further includes a first female connector adapted to be formed on a side face of the second object, a second cutout adapted to be defined in the side face of the second object and a second female connector formed on a side face defining the second cutout so that the first female connector and the second female connector are zigzag to each other. Therefore, insertion of the first male connector and of the second male connector into the first female connector and the second female connector, respectively, redistributes the weight of the combination evenly. 
   Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   With reference to  FIGS. 1 and 2 , it is noted that the connection assembly in accordance with the present invention include a pair of male connectors ( 1 ) formed on a side face of a first object (A) and a pair of female connectors ( 2 ) formed on a side face of a second object (B). 
   The pair of male connectors ( 1 ) is composed of a first male connector ( 11 ) formed on a longitudinal side face of the first object (A), a first cutout ( 12 ) defined in the longitudinal side face of the first object (A) and a second male connector ( 13 ) formed and extending out from a side face defining the first cutout ( 12 ). Due to the provision of the first cutout ( 12 ), the first male connector ( 11 ) is zigzag to the second male connector ( 13 ). That is, in this preferred embodiment, the second male connector ( 13 ) has a length the same as the depth of the first cutout ( 12 ) so that the second male connector ( 13 ) is flush with the longitudinal side face of the first object (A). Each of the first male connector ( 11 ) and of the second male connector ( 13 ) has a tongue ( 111 ,  131 ) respectively stamped in the first male connector ( 11 ) and in the second male connector ( 13 ), a boss ( 112 ,  132 ) respectively formed on a mediate portion of the tongue ( 111 ,  131 ) and a wedge ( 113 ,  133 ) formed on a free end of the tongue ( 111 ,  131 ). Due to the provision of the first cutout ( 12 ), the first male connector ( 11 ) is zigzag to the second male connector ( 13 ). That is, the first male connector ( 11 ) is not in linear alignment with the second male connector ( 13 ). 
   The connection assembly of the present invention further includes a first female connector ( 21 ) formed on a longitudinal side face of the second object (B) to correspond to the first male connector ( 11 ) of the first object (A), an extension ( 22 ) protruding from the longitudinal side face of the second object (B) formed on a side face of a longitudinal side face of the second object (B) and a second female connector ( 23 ) formed on a free side of the extension ( 22 ) to correspond to the second male connector ( 13 ) of the first object (A). It is noted that due to the provision of the extension ( 22 ) on the second object (B), the first female connector ( 21 ) is zigzag to the second female connector ( 23 ). Furthermore, each of the first female connector ( 21 ) and of the second female connector ( 23 ) has a indentation ( 211 ,  231 ) respectively defined in the bottom face of the longitudinal side face and of the extension ( 22 ) to correspond to and receive therein the first male connector ( 11 ) and the second male connector ( 13 ), respectively. In addition to the indentation ( 211 ,  231 ), the first female connector ( 21 ) and the second female connector ( 23 ) each have a through hole ( 212 ,  232 ) defined through a side face defining the indentation ( 211 ,  231 ) to receive therein the bosses ( 112 ,  132 ) of the first male connector ( 11 ) and of the second male connector ( 13 ). Two guiding holes ( 24 ) are defined along the longitudinal side face of the second object (B) and two guiding wedges ( 14 ) are formed on the longitudinal side face of the first object (A) such that the two guiding wedges ( 14 ) are able to extend into the two guiding holes ( 24 ) to combine the first object (A) with the second object (B). 
   With reference to  FIGS. 3 and 4 , when the first object (A) is combined with the second object (B), the first male connector ( 11 ) and the second male connector ( 13 ) are respectively inserted into the corresponding indentations ( 211 ,  231 ) with the boss ( 112 ,  132 ) from the first male connector ( 11 ) and the second male connector ( 13 ) received in the corresponding through holes ( 212 , 232 ).  FIG. 4  shows the boss ( 112 ) of the first male connector ( 11 ) being received in the corresponding through hole ( 212 ) of the first female connector ( 21 ). 
   From the above mentioned description, it is noted that the first male connector ( 11 ) is zigzag to the second male connector ( 13 ). Also, the first female connector ( 21 ) is zigzag to the second female connector ( 23 ). Due to the zigzag relationship between the pair of male connectors and the pair of female connectors, the overall weight is evenly distributed between the first object (A) and the second object (B). 
   In addition to the pair of male connectors and the pair of female connectors, auxiliary wedges ( 15 ) are respectively formed on a side face defining the first cutout ( 12 ) and a side wall of the first object (A). Corresponding to the auxiliary wedges ( 15 ), there are locking holes ( 25 ) defined along the longitudinal side face of the second object (B) and the side face of the extension ( 22 ). Therefore, extending the auxiliary wedges ( 15 ) into the locking holes ( 25 ), the combination between the first object (A) and the second object (B) is firmly secured. 
   Because of the zigzag structural relationship between the pair of male connectors and between the pair of female connectors, after the combination between the first object (A) and the second object (B), the overall weight of the combination is evenly distributed so that the connection assembly of the present invention is well maintained even during transportation thereof. 
   It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
