DIY TABLE WITH EASY TO ASSEMBLE/DISASSEMBLE MECHANISM

Technical Field

Industrial and commercial

Background of Invention

In general, table consists of top and legs that are made out of a single material or could be divided to top and legs. The latter requires tools for assembling and disassembling. For example, a collapsible table which consists of folding mechanism attached to legs and top with a "c" shape structure, with pivot at the central axis and collapsible bracing providing additional support. It is time consuming and cumbersome to assemble and disassemble since it requires tools such as wrench or screwdriver.

Another example is a table prevalent in Chinese restaurants where the tabletop and leg are separated. A pair of U-shape legs is connected with a hinge in the middle to become a pivot point. To use the table, the legs are rotated open to become a stand to receive the tabletop.

The advantages of this type of table are quick and convenient to use and to store. One drawback of this system is the fact that the tabletop is simply resting on the leg stand, which makes it not secure and safe during usage.

Other tables such as office table or computer table have the tendency to come with many parts and pieces, which requires tools for assembly rendering the experience cumbersome.

Brief Description

To resolve all the above-mentioned troubles, an invention of a mechanism that allows easy assembly of legs to tabletop is borne. The DIY Table with easy to assemble/disassemble mechanism consists of a tabletop and one pair of legs. The legs are equipped with anchoring pin that can be slid into receptacles embedded to the underside of the tabletop. In addition, there is also a rail system embedded to the underside of the tabletop. This rail system affords easy connection of the tabletop and accessory trays.

One of the intentions is to make table assembling simple and without mechanical tools.

One of the intentions is to make the assembling process so simple that even a child or a woman can assemble the table.

Detailed Description

The description of the DIY Table with easy to assemble/disassemble mechanism will make reference to the above-mentioned illustration for clarity.

Fig.1-4 demonstrates components of the DIY Table with easy to assemble/disassemble mechanism, which consists of tabletop (1), legs (2), accessory trays (21), and a locking mechanism for leg (6) embedded to the underside of the tabletop. The locking mechanism consists of three-sub components: upper layer (9), middle layer (8), and bottom layer (7) which forms a receptacle for the anchoring pin. The three layers are held together and to the underside of the tabletop with a fastener (not shown).

The upper layer (9) of the locking mechanism is square in shape and is thinner than the middle layer (8). This thin upper layer has a U-shape cut (13) and a small latch in the middle (14). The latch is slightly bent downward to accommodate the depressed area (15) on top of the anchoring pin (5).

The middle layer (8) of the locking mechanism is square in shape and has thickness. The center of this layer has a capsule-shape hole (12). Above this hole is a slot (10) for accommodating a coin to disengage the leg (2) from the tabletop (1).

The bottom layer of the locking mechanism (7) has corresponding slot (10) to that of the middle layer (8). At the center of this layer, there is a keyhole-shape hole (1 1) to accommodate the anchoring pin (5) attached to the leg (2).

The lower part of the pin (5) is a hollowed cylinder threaded to accommodate a fastener. The end of it has been shaped to create a snug fit with the tubular leg (2). The top part of the pin has two discs of different sizes. The smaller disc is locating on top while the larger one is situated just to the bottom of the smaller disc while their centers are connected to the vertical axis of the anchoring pin. The distance between the two discs produces a groove (22). This groove and the depressed area on top of the smaller disc (15) accommodate a small latch (14) from the upper layer (9) of the locking mechanism.

The anchoring pin (5) is attached to the tubular leg (2) by way of a fastener (not shown). The end of the leg is comprised of a smaller dowel (3) for enclosure and a round smooth pad (4) to provide stability to the table.

The underside of the tabletop, along its edge, is routed out to accommodate a rail system (16). There are holes (17) on the surface of the rail to allow it to be fastened to the underside of the tabletop. In addition, there are recessed keyhole-like holes (18) to accommodate pins (19) of the accessory trays. The profile of the pin (19) is the same with the top part of the pin (5) mounted to the tubular leg (2).

The anchoring pin (as shown in fig.6) is attached to the top of a plate (20). A portion of this plate is also attached to the bottom of an accessory tray (21) with a fastener (not shown).

Fig. 5 illustrates attachment and detachment of an anchoring pin on the leg (5) into the smaller diameter of the keyhole-shape hole (1 1) of the bottom layer (7) of the locking mechanism (6) by using a coin. The smaller diameter part of the keyhole-shape hole is smaller than the capsule shape hole (12) of the middle layer (8) creating a discrepancy (23) between the keyhole-shape hole and the capsule shape hole, which serves as a slot (22) to receive an anchoring pin.

As the above-mentioned pin is being inserted into the bottom layer (7), the small latch (14) of the upper layer (9) of the locking mechanism is pushed down into the depressed area (15), which then prevents the pin from moving.

By inserting a coin (30) into the slot (10) on the bottom layer and the middle layer (8) of the locking mechanism, the coin causes the end of the U-shape plate of the upper layer (9) to lift up.

This action releases the latch (14) from the depressed area (15) allowing the pin to be detached from the keyhole-shape hole (1 1) of the locking mechanism.

Fig. 7 illustrate the underside of the tabletop with the rail system without the accessory tray.

Fig. 8 illustrate the underside of the tabletop with the rail system with the accessory trays.

Fig. 9 illustrate an axonometric drawing of The DIY Table with easy to assemble/disassemble mechanism with two accessory trays.

This invention allows transformation of the tabletop into something other than a rectangular shape. The rail system attached to the underside of the tabletop affords multiple accessory trays capable of forming different configurations.

By pushing the anchoring pin on top of the leg to the locking mechanism installed to the underside of the table, the process is complete quickly and conveniently. With accessory trays, the table has added functionalities.

Finally, note that the above embodiments are merely used for the present aspect of the invention, not limitation, other modifications to those of ordinary skill in the technical aspect of the present invention is made or equivalents without departing from the technical spirit of the present invention and range, which may be included in the claims of the present invention of claim scope.
