## Background
FIELD OF THE INVENTION
The present invention relates to a hanging table and particularly to a foldable hanging table.
BACKGROUND OF THE INVENTION
Many people have paid much attention to leisure life quality and household activities nowadays. Many community gardens, backyards, public parks or house balconies often serve as people's meeting and chatting venues. To provide resting or meet visual art requirement, many of those locations have fixed table tops attached to handrails to hold potted landscapes, leisure parasols, lamp sets, teat sets or the like.
In order to provide a table top for hanging on handrail, U.S. Pat. No. 5,653,178 discloses a railing supported folding table which includes a first frame, a second frame and a table top. The table top is hinged on the first and second frames through at least one pivotal member, and then is mounted onto a handrail through a first adjustment hook and a second adjustment hook. The first and second adjustment hooks are installed respectively on through holes formed on the first and second frames, and then are fastened firmly via fasteners to securely hang the table top on the handrail. Because the table top is hinged on the first and second frames merely through the pivotal member, the pivotal member tends to loosen off after repeatedly flipping or folding of the table top for a prolonged period of time to result in incline of the table top. Moreover, with only the pivotal member serving as a support spot, when the table top is loaded with heavy goods, the support could become insufficient to result in collapse of the table top and drop of the goods.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to FIGS. 1 through 4 for a first embodiment of the foldable hanging table of the invention. The foldable hanging table comprises a table panel 20, a suspension assembly 30 and a folding assembly 40 that aims to be hung on a construction structural body 10. The construction structural body 10 has a leaning top surface 11 formed at a selected width. The table panel 20 has a loading surface 21, a connection surface 22 opposite to the loading surface 21 and a hinge portion 23. The suspension assembly 30 includes a support rack 31, at least one suspension arm 32, an adjustment member 33 and a fastener 34. The support rack 31 is hinged by the hinge portion 23 of the table panel 20. The suspension arm 32 is connected to the support rack 31 and straddles the construction structural body 10 to lean on the leaning top surface 11. The suspension arm 32 is formed at a length at least greater than the width of the leaning top surface 11 and has a plurality of anchor holes 321 formed thereon and equally spaced from each other. The adjustment member 33 has an anchor portion 331 (such as an anchor strut) and an aperture 332. When the suspension arm 32 leans on the leaning top surface 11, the anchor portion 331 of the adjustment member 33 can be anchored by one of the anchor holes 321 selected according to the width of the leaning top surface 11. Then the fastener 34 can run through the aperture 332 of the adjustment member 33 to tightly press against the construction structural body 10, thereby the table panel 20 can be hung on the construction structural body 10.
The folding assembly 40 includes a swivel frame 41 and a driven member 42. The swivel frame 41 is hinged on the connection surface 22 of the table panel 20 and has at least one detent plate 411. The driven member 42 is hinged respectively on the support rack 31 and swivel frame 41, and includes at least one holding portion 421, at least one driving portion 422 and a grip handle 423. The holding portion 421 aims to confines the swivel frame 41 from swiveling against the table panel 20. The driving portion 422 is connected to the holding portion 421. The grip handle 423 is connected to the driving portion 422. The driven member 42 further has a housing space 424 and an elastic element 425 (such as a spring) held in the housing space 424 to provide a compression displacement to allow a user to grip the grip handle 423 and exert a force towards the suspension assembly 30, thereby the compression displacement provided by the elastic element 425 can drive the driving portion 422 to make the holding portion 421 separate from the swivel frame 41 so that the swivel frame 41 can swivel as desired.
In this embodiment, the foldable hanging table mainly has the hinge portion 23 of the table panel 20 hinged on the support rack 31, and then the support rack 31 straddles the construction structural body 10 via the suspension arm 32, thereby the table panel 20 is hung on the construction structural body 10. The swivel frame 41 is hinged on the connection surface 22 of the table panel 20. The holding portion 421 (such as a hook) is fixed on the swivel frame 41 to confine the swivel frame 41 from swiveling against the table panel 20. Moreover, the detent plate 411 also confines the swivel frame 41 from swiveling too much against the driven member 42. As a result, the loading surface 21 of the table panel 20 and the construction structural body 10 can be formed in an unfolding condition at a vertical angle. The table panel 20, aside from being hinged on the support rack 31, also is hinged on the swivel frame 41. Hence the support rack 31 and swivel frame 41 can serve as support means to increase the support and maintain the table panel 20 at a horizontal condition without tilting. Furthermore, a user can grip the grip handle 423 and exert a force towards the suspension assembly 30; through the compression displacement provided by the elastic element 425, the driving portion 422 is driven to make the holding portion 421 separate from the swivel frame 41, thereby the swivel frame 41 can swivel towards the connection surface 22 of the table panel 20 (i.e., the turning direction A), and the driven member 42 also can swivel towards the support rack 31 (i.e., the turning direction B) to make the loading surface 21 of the table panel 20 form a folding condition at a horizontal angle against the construction structural body 10. Through the driven member 42 driving the swivel frame 41 to swivel against the table panel 20, the table panel 20 can swivel against the support rack 31 to facilitate folding of the table panel 20, thereby improve usability.
Please refer to FIGS. 5 and 6 for a second embodiment of the invention. It is substantially constructed like the first embodiment previously discussed. The main difference is a horizontal adjustment assembly 50 which includes an adjustment rack 51 and a guide member 52. The adjustment rack 51 is hinged on the support rack 31 and has a butting portion 511 leaning on the construction structural body 10. The guide member 52 has one end hinged on the adjustment rack 51 and a guide track 521 with at least one anchor notch 522 formed therein. The support rack 31 has a guide boss 311 running through the guide track 521 and movable along the guide track 521 to drive the adjustment rack 51 leaning on the construction structural body 10 to generate skewness; in addition, the guide boss 311 enters the guide track 521 and skew from the axial direction of the guide track 521 and anchor on the anchor notch 522, thereby the loading surface 21 of the table panel 20 can be adjusted at the horizontal condition, hence the tilting problem of the table panel 20 caused by different widths of the leaning top surface 11 and construction structural body 10 when the support rack 31 is hung on the construction structural body 10 can be resolved. In addition, the guide member 52 has an arched inclined portion 523 to keep the table panel 20 at the horizontal condition without tilting downward during adjustment. Moreover, it is to be noted that, the guide member 52, guide track 521 and anchor notch 522 are not limited to the structures or shapes or quantity depicted in the embodiment. The embodiment mentioned above serves merely for illustrative purpose and is not the limitation of the invention.
Please to FIGS. 7 and 8 for a third embodiment of the invention. It is substantially constructed like the first embodiment previously discussed. The main difference is a horizontal adjustment assembly 50 is added that includes an adjustment rack 51, at least one horizontal retainer 53 and at least one fine-tune member 54. The adjustment rack 51 is hinged on the support rack 31 and formed at a width greater than that of the support rack 31, and has a butting portion 511 leaning on the construction structural body 10. The horizontal retainer 53 is located on the support rack 31 and has a fine-tune aperture 531 run through by the fine-tune member 54 so that one end of the fine-tune member 54 can be turned to make another end thereof butting against the adjustment rack 51 to drive the adjustment rack 51 to generate skewness, thereby adjust the loading surface 21 of the table panel 20 at the horizontal condition, hence the tilting problem of the table panel 20 caused by different widths of the leaning top surface 11 and construction structural body 10 can be resolved. Moreover, as the width of the adjustment rack 51 is greater than that of the support rack 31, when the leaning top surface 11 and construction structural body 10 have the same width, the tilting problem does not occur. By turning one end of the fine-tune member 54, another end thereof can be loosened from the adjustment rack 51, thereby the adjustment rack 51 can be moved close to the support rack 31 to retract the support rack 31 in the adjustment rack 51; namely, the support rack 31 and adjustment rack 51 can be maintained at the same horizontal plane at a frame thickness (the thickness of the support rack 31 or the thickness of the adjustment rack 51), thereby the table panel 20 can be positioned at the horizontal condition.
In short, the foldable hanging table of the invention mainly is hung on a construction structural body with a leaning top surface formed at a selected width. The foldable hanging table comprises a table panel, a suspension assembly and a folding assembly. The suspension assembly includes a support rack hinged by the table panel and at least one suspension arm connecting to the support rack and straddling the construction structural body to lean on the leaning top surface. The suspension arm is formed at a length at least greater than the width of the leaning top surface. The folding assembly includes a swivel frame hinged on the table panel and a driven member hinged respectively on the support rack and swivel frame. The driven member includes at least one holding portion to confine the swivel frame from swiveling against the table panel and at least one driving portion connected to the holding portion and operable to make the holding portion separate from the swivel frame so that the swivel frame can swivel as desired. Thus, the suspension arm can be adjusted according to the width of the construction structural body, and also increase support and improve usability.
