BACKGROUND OF THE INVENTION

The present invention related to a stand, in particular a stand for use with a table with foldable legs.

In general, tables, especially the ones with foldable legs, for example, seminar tables or meeting tables or the like are demanded in a great number for each usage. This leads to the problem of storage. The legs of these tables are usually folded and lean against each other or stacked. As a result, problems including damages of the tabletop surface such as scratch marks from the table legs while being stacked are common. Further, collapsing or slippage of the stacked table or while leaning against each other are also common. This may cause injury to the operators.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide a stand for use in the storage of the foldable-leg tables to facilitate the storage when not in use. This will save the storage space, reduce damages resulting from the abrasion causes by stacking of tables 1, and reduce risks of danger due to the improper storage that will otherwise cause the slippage of the table to bump against or fall over the operator. It further facilitates moving of these tables with less effort and ease. The stands in accordance with the present invention include at least one pair of stands mounted to the back surface of a table. The stand is extendable during usage and retractable to the back or underside of the table body when the table is in used.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, a pair of a stand 10 in accordance with the present invention is mounted to the back of the foldable-leg table. Each of the stand 10 is spaced-apart for an optimum distribution of load of the table to ensure balance of the placement. Each stand 10 comprises a base portion 15 and a body portion 20 connected thereto.

A base portion 15 is a downwardly facing semi-rectangle-like frame. That is, it is formed of a longitudinal shaft 20 whereby each end of the shaft 20 is coaxially bent downward defining leg portions 30, 30″ integrally formed at each end of the shaft 20 deriving the semi-rectangle-like frame. The bent corner of the leg portions 30, 30″ are preferably round to minimize or mitigate the injury in case of the accidental collision or impact with the leg portion 30, 30″ as shown in FIG. 1 and other Figures. One end of the leg portion 30″ may further comprise a wheel 35 to increase the convenience in moving or relocating the table. For the sake of the material saving and the manufacturing cost saving, the base portion 15 should be made of hollow durable material but have proper thickness to ensure strength and ability to withstand the load or the table weight.

A body portion 20 is formed, preferably of the same material as with the base portion 15 and is fitted perpendicularly to the base portion 15 It is mounted toward one of the legs 30, 30″, i.e., away from the center [off-center], of the spaced-apart legs 30, 30″. As shown in FIG. 1, in the embodiment where the end of the leg 30″ includes a wheel 35, the body portion 20 is off-center mounted toward the leg 30 with no wheels 35 installed thereto. This is so arranged to prepare a space at the shaft 25, between the body 20 and the leg 30″ of which installed with the wheel 35 to accommodate the table edge allowing the load to be directed to the center of the base 15 creating a balance of weight avoiding excessive load exerted on either front or back side that may cause the table to stumble or fall over to either sides.

The body portion 20 is a hollow cylinder comprising the outer body 40 and the inner body 45 nested together. The inner body 45 is longer than the outer body 40 and is smaller in diameter than the outer body 40 allowing the inner body to be slidable inside the outer body. The body portion 20 is hence, able to telescope longitudinally. One end of the inner body 45 is permanently connected to the base portion 15.

The inner body 45 is provided with two spaced-apart stopper holes, which are the first stopper hole 50 and the second stopper hole 55 prepared along the length of the inner body 45. The distance between the spaced-apart stopper holes determines how much the stand 10 is able to extend from the table edge or retract to the inner portion of the lower part of the table 100 in such a manner that when it is extended, the table edge will coincide with the shaft 25 of the base portion 15 to allow the shaft 25 of the base portion 15 to bear the weight of the table body. Further, when the stand is not in use, that is, when the table is taken out for use, the stand 10 is retracted to the inner part of the table 100 leaving no portions of the stand 10 protruding out of the table edge.

Size of the first and second stopper hole 50, 55 stopper corresponds to the size of a spindle 60 of a stopper 65 arranged at the outer body 40 to accommodate the spindle 60 of the stopper 65 fitted to the outer body 40 as will be later described.

As mentioned above, other than being provided with a certain distance along the length of the inner body 45, the first stopper hole 50 and the second stopper hole 55 are also provided at different positions on the circumference of the inner body 45. That is to say, the first stopper hole 50 and the second stopper hole 55 are approximately 90 degrees apart on the circumference of the inner body 45 permitting turning and securing [locking] the stand 10 at the required positions or postures, i.e. when not in used as shown in FIG. 3 or when in used as shown in FIG. 4.

Further, at the tip of the inner body 45, opposite to the shaft 25 includes a guide cap 70 serving to cover the inner body 45 which is a hollow tube as well as prevents the inner body 45 from unintentionally sliding out of the outer body 40. The guide cap 70 also serves to determine the position that the user turns the inner body 45. By turning the base portion 15 connected to the inner body 45, the turning will bring the first stopper hole 50 or the second stopper hole 55 of which their respective positions are out of view [conceal the outer body 40] into the position where the spindle 60 of the stopper 65 of the outer body 40 engaged thereto when the position of the stand 10 is required to be locked for the retraction during storage or unlocked so as to allow extension of the stand 10, the detail operation of which will be further discussed below

The outer body 40 is a hollow cylindrical tube sheathing the inner body 45 with the length that is shorter than that of the inner body 45 and mounted with the brackets 75. Shown in FIGS. 1-7 is the embodiment including one pair of the brackets 75 at each end of the outer body 40. Each pair of brackets 75 is connected at the left and right of the outer body 40 and each side of which is provided with a hole 80 to receive a fastening member, for example, a threaded screw for securing the stand 10 to the lower portion of the table 100 once the stand 10 is mounted to the table body.

At the outer body 40, there is provided a stopper 65 with a spring-type spindle 60 mounted thereto. The stopper includes the spring-type pin comprising a head 61 for gripping and a rod-like spindle 60 kept in a box-shape spindle chamber 62. The size of the spindle 60 corresponds to that of the size of the stopper holes 50, 55 provided at the inner body 45 and the length correspond to the distance from the head 61 across the spindle chamber 62 and through the through hole 64 of the outer body 40 and the inner body 45 to the hollow inner portion of the inner body 45. A coil spring 63 is mounted to the spindle 60 providing a spring-action permitting the spindle 60 to be pulled out of or pushed back into the stopper holes 50, 55. This will allow the locking and the unlocking between the outer body 40 and the inner body 45. For the stand 10 to extend and retract and for the ease of the retraction and the extension of the stand 10, the spindle chamber 62 includes two retention walls and are provided with sufficient space to retain the spindle 60 of the stopper 65. That is, when the stand 10 is required to be retracted or extended, the spindle 60 of the stopper 65 which is of the spring type will be pulled out from the stopper hole 50, 55 to unlock the outer body 40 and the inner body 45 from each other and is manipulated to bias and abut either corner of the spindle chamber 62 and the spindle 60 allowing the inner body 45 to slide in and out in order to facilitate the retraction and the extension. When locking is required, the spindle is pulled back and is manipulated to be inserted into the stopper hole 50, 55 again.

As shown in FIG. 3, in use, stand 10 is mounted to the lower portion of the table 100 by fasteners such as a screw, a bolt or the like to secure the stand 10 to the lower part of the table 100 through the hole 80 provided at the bracket 75. When not in use, the stand 10 is stored away by locking the inner body 45 of the stand 10 to the outer body 40 through the first stopper hole 50 of the inner body 45. The leg portions 30, 30″ of the base portion 15 retracted inward away from the edge of the table 100 to prevent the part of the stand 10 or its respective parts from extending beyond the table edge when the table 10 is in used. It can be seen from FIG. 3 that the inner body 45 can be rotated inside the outer body 40 for the distance of 180 degrees. Alignment of the first stopper hole 50 or the second stopper hole 55 with the position of the spindle 60 of the stopper 65 to lock the inner body 45 and the outer body 40 together can sometimes become difficult as the first stopper hole 50 or the second stopper hole 55 is hidden inside the outer body 40. The inner body 45 thus includes the guide cap 70 to align the first stopper hole 50 or the second stopper hole 55 with the position of the spindle 60 of the stopper 65 as mentioned above that the first stopper hole 50 or the second stopper hole 55 is 90 degree apart on the circumference of the inner body. The guide cap 70 includes the first brace 71 and the second brace 72, restricting the inner bodies 45 to be turned at no more than 90 degrees. That is, when not in use, the stand 10 is retracted in the storage position by locking the inner body 45 of the stand 10 to the inner body 45 through the first stopper hole 50 and in this position the second brace 72 is perpendicular to the underside surface of the table 100. In FIG. 4, when the stand 10 is pulled out to be used, the inner body 45 is extended in a sliding manner and turned for 90 degrees to turn the second stopper hole 55 to the position of the spindle 60 of the stopper 65. In such a manner, the guide cap 70 will be slid to abut the upper end of the outer body 40 while the first brace 71 is turned to the exact perpendicular position with the underside surface of the table 100. This thus locks the inner body 45 and the outer body 40 together. The base portion 15 will then abut the table edge while the leg portions 30″ of the shaft 25 with the wheel 35 attached thereto, or in the embodiment without the wheel 35, the leg 30 at farther side of the body portion 20, will be turned 90 degrees and thus makes the leg portions 30″ with the wheel 35 or the leg 30 on the farther side of the body portion 20 extends beyond the front (upper surface) side of the table. Therefore, all of the table weight is exerted on the shaft 25 of the base portion 15 immediately adjacent to the table edge when the stand 10 is placed vertically as shown in FIG. 5.

FIG. 6 and FIG. 7 show mounting of the stand 10 to the underside of the table 100, especially, the side without an obstruction of table's foldable legs mounted thereto. FIG. 6 shows an embodiment of the leg portions 30″ with the wheel 35 while FIG. 7 shows the embodiment without the wheel 35. The embodiment with the wheel 35 is more preferable since it will mitigate the load allowing moving of the table with ease. As shown in FIG. 8, during the use, the table edge will precisely abut the shaft 25 of the base portion 15. If the table needs to be moved, the mover simply tilts the table until the side with no wheel 35 is lifted off the floor and pushed forward to the desired position. This will increase ease and reduces required man power of lifting equipment for the moving.

As shown in the exemplary embodiments, the stand 10 in accordance with the present invention is suitable for the mounting with the non-decorative side edge, that is, the plain-edge table. This is due to the fact that the side edge of the table will obstruct the in-out sliding for the retraction or the extension of the stand. However, if it is used with the table with edges, the bracket 75 of the stand 10 may be modified to lift the body portion 20 of the stand 10 to the extent higher than the width or the height of the decorative edge. This will allow the inner body 45 to be slid in and out along the length of the outer body 40 to retract and extend the stand 10.

According to the above details, it can be seen that the stand facilitates the storage of the foldable-leg tables when not in use. It helps to save storage space, reduce damages from the abrasion of the table legs [as the table may be stand upright without the need of stacking], and reduce risks of danger due to the improper storage that will otherwise cause the slippage of the table to bump against or fall over the operator. It further eases the moving of these tables with less effort, manpower of lifting equipments and hence, meets the objective of the present invention.

Although the detailed disclosure of the present invention is the exemplification of the implementation of the stand in accordance with the present invention with other articles including a board, a panel, a partition, and the like.
