1. Field of the Invention
The present invention relates to a ganging device for a folding chair, and in particular to a ganging device that can enlarge a gap between connected chairs to offer comfortable seating.
2. The Prior Arts
The folding chairs are arranged in rows for indoor and outdoor events such as meeting, party, and reception. In order to provide an orderly seating arrangement, the folding chairs are neatly lined up and then interconnected with ganging devices. Referring to
A primary objective of the present invention is to provide a ganging device mounted between folding chairs. The ganging device not only connects the chairs together but also keeps an ample distance between the chairs allowing spacious seating.
The solution of the present invention is to provide a frame as a main member of the ganging device. A first side of the main member includes an engaging protrusion, a fixing hole and a fixing element corresponding to the fixing hole. A second side of the main member includes a bottle-shaped frame slot having a narrow neck portion and a wide body portion. Moreover, a slot fastener is welded to a front leg frame of the chair. The slot fastener includes a bottle-shaped engaging slot having a body portion and a neck portion. An engaging knob is disposed on another folding chair.
The fixing element includes a screw, a nut and a washer. A screw head of the screw is inserted into the body portion of the engaging slot and then the screw is glided down the neck portion of the engaging slot. Then, a shank of the screw passes through the fixing hole and the engaging protrusion is fitted into the body portion of the engaging slot. The washer and nut of the fixing element are screw into the screw, thereby fixing the main member with the front leg frame of the chair. The engaging knob on another chair is inserted into the body portion of the frame slot of the main member and is glided down to the neck portion of the frame slot of the main member, thereby connecting the engaging knob with the main member. Therefore, the chairs are connected side by side.
The ganging device for enlarging a gap between folding chairs according to the present invention uses knobs and slots to quickly connect the chairs together. If trying to disconnect the folding chairs, it only needs to disengage the knobs and slots. It is quick and convenient.
A width of the main member of the ganging device is about 5 cm and the ganging device mounted between the folding chairs can keeps a distance between the chairs. Thus people sitting next to each other can enjoy the spacious seating and will not feel be confined in a small space.
The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:
A ganging device 4 for a folding chair in accordance with the present invention is mounted between two folding chairs to enlarge a gap between the connected folding chairs. The ganging device 4 includes a main member 1 to increase the gap, and a slot fastener 2 and a knob fastener 3 located at respectively associated opposite sides of a front leg frame of the folding chair.

When the main member 1 is mounted to the slot fastener 2 on a first chair, the screw head of the screw 121 is inserted into the body portion of the engaging slot 21 and the screw 121 is pushed down to the neck portion of the engaging slot 21, thereby holding the screw head of the screw 121 between the slot fastener 2 and the front leg frame. The shank of the screw 121 is inserted into the fixing hole 14 of the main member 1 and the engaging protrusion 11 is fitted into the body portion of the engaging slot 21 of the slot fastener 2. Then, the washer 122 is sleeved on the shank of the screw 121 and the nut 123 is securely screwed down the screw 121. Therefore, the main member 1 is connected with the slot fastener 2 and is securely mounted on the front leg frame of the first chair. Because the engaging protrusion 11 is fitted into the body portion of the engaging slot 21, the main member 1 can not be rotated relative to the slot fastener 2. The engaging knob 31 of the knob fastener 3 on a second chair is inserted into the body portion of the frame slot 13 on the main member 1 and the engaging knob 31 is pushed down to the neck portion of the frame slot 13. Thus, the knob fastener 3 on the second chair is engaged with the main member 1 mounted on the first chair. Therefore, the first chair and the second chair are connected by the ganging device according to the present invention as shown in
However, when two chairs are connected by only one ganging device 4, the chairs may shift relative to each other. The solution of the problem mentioned above, is to provide more than one ganging devices 4 to connect the first chair and the second chair. Referring to

Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
