Patent Description:
According to <CIT> a collapsible iron board with legs is disclosed. The board consists of three sections with two hinges to allow folding of the end sections and to overlay the central section. The collapsible support legs are formed from two pivotally coupled legs, wherein each leg is telescopic with a separable foot element. On eof the legs is hinged to the underside of the central board section, while the other one is releaseably anchored in a mounting via a pin. Each foot element has a projecting tongue element which snap-fits into a clamping element. The whole of the collapsible support leg arrangement is stowed adjacent to the underside of the central board section and is within the platform area of it.

That is, compactness of conventional collapsible, adjustable height tables often corresponds to the distance of the vertical excursion. For example, the legs of an ironing board may be a limiting factor in the minimum width of the collapsed apparatus. If the ironing surface is reduced in size, the legs would extend beyond the width of the ironing surface when the apparatus was collapsed, and thus, the overall dimensions of the collapsed apparatus would not be reduced. If the length of the legs is shortened, the desired ironing board height would not be achieved. Thus, with ironing boards, and other folding, adjustable apparatuses, such as folding tables, desks and standing tables, the dimensions of the collapsed apparatus are dictated by the maximum height of the apparatus.

The present invention addresses a table in accordance with claim <NUM>. Preferred embodiments are depicted in the dependent claims.

A collapsible, adjustable height table is disclosed that provides a reduced folded size compared to conventional collapsible, adjustable tables and other apparatuses. This multi-purpose apparatus may include a gas compression spring, or similar mechanism, to facilitate extending the table to desired heights. The novel telescoping legs enable use of a central pivot about which the legs rotate to fold and expand the table, wherein the pivot apparatus does not limit the length of the legs, and therefore does not limit the height of the table.

The detailed description refers to the accompanying figures, which depict illustrative embodiments.

<FIG>, <FIG>, <FIG>, <FIG> depict an illustrative collapsible, folding table <NUM> in various configurations. <FIG>, <FIG>, <FIG>, <FIG> show simplified depictions of various illustrative configurations. Optionally, stops, detents or other mechanisms may be incorporated to signal when a table is at a particular height, and/or maintain it in the desired position. These heights may represent coffee table, sitting table and standing table configurations, or they may include additional height options or fewer height options.

<FIG> depict a perspective view, bottom view, and side view, respectively, of table <NUM> in a folded position. <FIG> depicts a perspective bottom view of a table in a deployed position. <FIG> depict a side view, a perspective bottom view, and a perspective upright view, respectively, of table <NUM> elevated to or toward its maximum height. This height may be used, for example, as a standing table. <FIG> depict a side view and a perspective bottom view, respectively, of table <NUM> elevated to or toward its maximum height. This height may be used, for example, as a sitting table. <FIG> depict a side view and a perspective bottom view, respectively, of table <NUM> elevated to a lower height than depicted in the previous figures. This height may be used, for example, as a coffee table. In each case, the height of table <NUM> is temporarily locked or secured in place. Reference to specific heights or table uses herein is for illustrative purposes and does not limit the scope of the invention.

The height of table <NUM> may be adjusted by scissoring the legs and/or extending them. The height of table <NUM> may be limited to a number of specific heights or may be continually adjustable between a minimum and maximum height.

Table <NUM> has a table top <NUM> having a top surface <NUM> and a bottom surface <NUM>. An apron <NUM> extends downward from bottom surface <NUM>. A first leg <NUM> and a second leg <NUM> extend from table top <NUM>. First leg <NUM> and second leg <NUM> may extend directly from table top bottom surface <NUM>, or may have components disposed therebetween, for example to facilitate attachment either fixedly or slidably.

First leg <NUM> has a top end <NUM> and a bottom end <NUM>, and a pivot <NUM> located between top end <NUM> and bottom end <NUM>. Similarly, second leg <NUM> has a top end <NUM> and a bottom end <NUM>, and a pivot <NUM> located between the top end <NUM> and the bottom end <NUM>. First leg <NUM> and second leg <NUM> are attached at pivots <NUM> and <NUM>. Pivots <NUM> and <NUM> (identified generally in <FIG>) may be, for example, pivot assemblies 212A, 212B as described below, or other pivot connections that allow first leg <NUM> and second leg <NUM> to scissor with respect to one another and are compatible with the folding mechanisms employed.

As can be seen in <FIG> with table <NUM> at or near its maximum height, first leg <NUM> and second leg <NUM> are telescopic. Each of first leg <NUM> and second leg <NUM> comprises two sections, a sleeve section <NUM>, <NUM> and an extension section <NUM>, <NUM>, wherein extension section <NUM>, <NUM> is internally slidable in sleeve section <NUM>, <NUM>. Sleeve section <NUM> is part of first leg <NUM>, which is the leg that is hinged to table top <NUM>. Sleeve section <NUM> is part of second leg <NUM>, which is the leg that is slidable with respect to table top <NUM>. Second leg <NUM> may be resistively, slidable with respect to table top <NUM> to the extent necessary for safety or ease of folding and expanding, for example. Second leg <NUM> may also be biased to resistively slide in increments.

<FIG> depict an illustrative leg assembly <NUM>, which can be incorporated in either first leg <NUM> or second leg <NUM>. Leg assembly <NUM> is shown with respect to a compartmentalized sleeve section <NUM>, such as sleeve sections <NUM>, <NUM>. Compartmentalized sleeve section <NUM> is divided longitudinally into a first larger enclosed space <NUM> and an adjacent second smaller enclosed space <NUM>. Leg extension sections <NUM>, <NUM> are dimensioned to telescope into the large enclosed space <NUM>, contained in each of sleeve sections <NUM>, <NUM>, whereas small enclosed space <NUM> houses the fastener for the leg pivot. Advantageously, this compartmentalized configuration of sleeve section <NUM> allows the telescoping leg to pass through the pivot axis. Although the two enclosed spaces are referred to as "small" and "large" or "smaller" and "larger," they need not have that relative dimensional relationship. More broadly, one compartment must be large enough to accommodate a leg extension and the other a fastening component to secure the pivot to the leg, to allow the leg extension to slide past the pivot. This may provide a greater degree of compactness of the folded configuration dimensions. It is further noted that the compartments need not be fully enclosed. For example, the smaller or second enclosed space merely needs to allow for fastening of a pivot assembly, and thus, may only need to occupy a small distance along the sleeve.

<FIG> depict an illustrative pivot apparatus <NUM> that extends into the smaller enclosed space <NUM> of each of first leg sleeve section <NUM> and second leg sleeve section <NUM>. <FIG> shows pivot apparatus <NUM> positioned on compartmentalized sleeve <NUM>. <FIG> is an enlargement of pivot apparatus <NUM>. An expanded view of components of pivot apparatus <NUM> are also shown in <FIG>. Pivot apparatus <NUM> includes a nut <NUM>, which fits within small enclosed space <NUM>. A pivot assembly <NUM> is positioned outside of compartmentalized sleeve <NUM>. Nut <NUM> and pivot assembly <NUM> are fastened to one another, for example, by a screw <NUM>. Nut <NUM> may be any shape or material that adequately secures mating pivot assemblies 212A, 212B, such as a plate, disk or other configuration. The term "nut" will be used broadly to include any such component.

Pivot apparatus <NUM> is attached between a first end <NUM> of sleeve section <NUM> and a second end <NUM> of sleeve section <NUM>, and further attached between a first end <NUM> of sleeve section <NUM> and a second end <NUM> of sleeve section <NUM>. Mating pivot assemblies 212A, 212B, which may be for example, a male or female pivot assembly component. Mating pivot assembly 212A is located on either first leg <NUM> or second leg <NUM>, and the complementary mating pivot assembly is located on the other of first leg <NUM> or second leg <NUM>. When engaged, mating pivot assemblies 212A, 212B rotate with respect to one another.

<FIG> depicts an isometric view of table <NUM> from the bottom, showing a portion of pivot apparatus <NUM>. An enlarged view is shown in <FIG> and includes a view of a mating pivot assembly <NUM>. A tab <NUM> is shown in mating pivot assembly 212A male component, which would engage with a female mating pivot assembly 212B female component.

<FIG> depicts an optional pivot housing <NUM>. Pivot housing <NUM> includes a first leg pivot housing component <NUM> having an opening through which the first leg sleeve component <NUM> is disposed and a second leg pivot housing component <NUM> having an opening through which the second leg compartmentalized sleeve component <NUM> is disposed. The first leg pivot component is rotatably attached to the second leg pivot component. Other configurations of pivot housing may be used that allow for rotation of first leg <NUM> and second leg <NUM> with respect to one another, including having the housing portions integral with the legs.

In an illustrative embodiment, each leg extension section <NUM>, <NUM> has a length allowing it to extend within its associated sleeve component <NUM>, <NUM> past pivot apparatus <NUM>. This is made possible by the compartmentalized structure of sleeve components <NUM>, <NUM>, which allows the telescoping parts to be accommodated within first enclosed space <NUM>, while second enclosed space <NUM> accommodates pivot apparatus <NUM>, thereby keeping the parts separated.

<FIG> depicts a bottom isometric view of table <NUM> having a lifting mechanism <NUM>, which may comprise a lift assist component such as a spring apparatus, or may be operated merely by a user applying a preferably light force to achieve the desired height. First leg top end <NUM> is fixedly attached to table top bottom surface <NUM>. Second leg top end <NUM> is slidably attached to table top bottom surface <NUM>. Pivot apparatus <NUM> is configured to attach first leg <NUM> to second leg <NUM> at first leg pivot <NUM> and second leg pivot <NUM>.

A track <NUM> is attached to table top bottom surface <NUM>. A first wheel <NUM> is attached to second leg top end <NUM> and allows second leg <NUM> to slide along table top bottom surface <NUM>. A second wheel <NUM> is disposed laterally opposite first wheel <NUM> and is attached to second leg top end <NUM>. Second wheel <NUM> is disposed within the track <NUM> and is slidable along track <NUM>. Second wheel <NUM> is rotationally attached to a pull bar <NUM>. A gas compression spring <NUM> having a first end <NUM> and a second end <NUM> is fixedly attached at its first end <NUM> to table top bottom surface <NUM> or an extension therefrom. Gas compression spring second end <NUM> is fixedly attached to pull bar <NUM>, thereby forcing spring <NUM> to compress when table <NUM> is collapsed and extend as table <NUM> is raised.

In illustrative embodiments, gas compression spring <NUM> is positioned off-center between the opposite sides of table top bottom surface <NUM>. This configuration facilitates table <NUM> folding flat or at least with a minimum depth as measure from table top surface <NUM>. Table <NUM> may be configured so folded components are within the depth of apron <NUM>. This may facilitate storing table <NUM>, such as underneath a bed or sofa, as it may slide more easily and table components are shielded from catching on objects. It remains adjacent, instead of under, various table components such as first leg <NUM> and second leg <NUM>. Although reference is made to compression spring <NUM>, a tension spring may be employed instead. For example, the mechanism comprising pull bar <NUM> and compression spring <NUM> can be replaced with a tension spring.

<FIG> depict the components of a locking and release mechanism to secure table <NUM> in a folded position. <FIG> show the locking mechanism with illustrative housing components. The locking and release mechanism comprises a storage catch <NUM> pivotably attached to table top <NUM>. Storage catch <NUM> has a hook <NUM>. An indent <NUM> in first leg <NUM> at first leg bottom end <NUM> is complementary to storage catch hook <NUM> to the extent necessary for hook <NUM> to engage indent <NUM>. Storage catch <NUM> is biased to engage first leg bottom indent <NUM>. A shuttle <NUM> is slidably attached in the locking and release mechanism from a first position engaging storage catch <NUM> and countering the bias of storage catch <NUM> toward first leg bottom indent <NUM> to unlock first leg bottom <NUM>, and a second position away from the storage catch <NUM> so as not to affect the bias of storage catch <NUM> toward first leg bottom indent <NUM>. <FIG> shows the locking mechanism engaged with a leg <NUM> when table <NUM> is in a folded position.

Shuttle <NUM> has an angled surface <NUM>. A table release lever <NUM> is movable toward and away from table top <NUM> and engaged with shuttle angled surface <NUM>, so as to force shuttle <NUM> to move away from storage catch <NUM> according to the engagement position of table release lever <NUM> with respect to shuttle angled surface <NUM>. The locking and release mechanism further includes a release rod <NUM> configured to release a gas spring release component to allow gas spring <NUM> to expand, thereby elevating table <NUM>.

<FIG> depict the illustrative table release mechanism that secures legs <NUM>, <NUM> in a folded position when the table is collapsed, and releases legs <NUM>, <NUM> to expand the table. <FIG> shows table <NUM> in the expanded position with table release lever <NUM> shown prior to it being depressed. Table release lever <NUM> operates hook <NUM> which is designed to latch onto a table leg. Release rod <NUM> is also operated by release lever <NUM>. Note the position of release rod <NUM> in slot <NUM>. As seen in <FIG>, when table release lever <NUM> is depressed, hook <NUM> is drawn into the housing surrounding table release lever <NUM>. Release rod <NUM> is forced to an opposing end of slot <NUM>. See the description above of <FIG> for additional information regarding the operation of release rod <NUM>. <FIG>, <FIG> are views of table <NUM> prior to releasing the legs from the folded position.

<FIG> shows a bottom view of table <NUM> in a folded position. Legs <NUM>, <NUM> are collapsed against table top <NUM>. Leg <NUM> is engaged with hook <NUM> (not visible). Leg release button <NUM> is identified to differentiate it from table release lever <NUM>. <FIG> shows table release lever <NUM> prior to it being depressed. <FIG> shows table release lever <NUM> being depressed and leg <NUM> disengaged from the mechanism to allow it to assume an expanded configuration.

Table <NUM> includes a telescoping leg locking mechanism in each of first leg <NUM> second leg <NUM>. <FIG> depict a top portion of the telescoping leg locking mechanism in a locked and unlocked configuration, respectively. <FIG> depict the bottom portion of the telescoping leg locking mechanism in a locked and unlocked configuration, respectively. The top and bottom portions are connected by connecting rod <NUM>. The telescoping leg locking mechanism includes a lock housing <NUM> disposed within each leg extension section <NUM>, <NUM>. Lock housing <NUM> may snap into extension sections <NUM>, <NUM>. A connecting rod <NUM> is engaged at a first end <NUM> with a leg extension release lever <NUM> and engaged at a second end <NUM> with lock housing <NUM> or components therein. A pair of opposing pins 184A, 184B extend laterally through the lock housing <NUM> and are configured to engage with openings <NUM> in leg sleeve components <NUM>, <NUM> to lock leg extension section <NUM>, <NUM>, respectively at a fixed height. When depressed, leg extension release lever <NUM> withdraws pins 184A, 184B from openings <NUM>, thereby allowing leg extension sections <NUM>, <NUM> to slide within leg sleeve components <NUM>, <NUM>.

A pin guide <NUM> extends from connecting rod <NUM>. Pin guide <NUM> has opposing slots 190A, 190B angled with respect to the longitudinal side of extension leg sections <NUM>, <NUM>. A spring <NUM> is disposed around connecting rod <NUM> within lock housing <NUM> and contained within lock housing <NUM> by a housing wall. Spring <NUM> biases pin guide <NUM> to force pins 184A, 184B into openings <NUM> of sleeve components <NUM>, <NUM>. Release lever <NUM> is configured to move connecting rod <NUM> to compress spring <NUM> against lock housing <NUM>, thereby withdrawing pins 184A, 184B from openings <NUM>. In addition to the incremental lengthening and shortening of the legs, a continuous adjustment may be incorporated to allow any selection between a minimum and maximum length. Various telescoping mechanisms may be used for the legs, provided they do not interfere with the pivot apparatus.

Advantageously, telescoping legs <NUM>, <NUM>, together with pivot apparatus <NUM> allow table <NUM> to be elevated to a substantial height and folded compactly, without legs <NUM>, <NUM> extending beyond the width of table top <NUM> (wherein the "width" is the greater of the table top dimensions). Therefore, a user need not give up height to achieve compactness. In an illustrative embodiment, table <NUM> has a width in the range of <NUM> to <NUM> and the table height is in the range of about <NUM> to about <NUM>. In a particular embodiment, the table width is about <NUM> and can reach a height of about <NUM> and yet legs <NUM>, <NUM> do not extend beyond the width of table top <NUM> when the table is collapsed. Various illustrative embodiments have a maximum height and maximum leg length greater than the width of the table, however, when in a folded configuration the legs do not extend beyond the width of the table while not being folded along their length. Disclosed embodiments also may lend themselves to lightweight, inexpensive construction, even for standing tables such as used in office environments.

Furthermore, table <NUM> is configured so that as it is elevated and second leg top end <NUM> slides across the width of table top <NUM> toward the first leg top end <NUM>, and therefore, away from the opposing edge of table top <NUM>, table <NUM> remains stable. The extent to which second leg top end <NUM> can slide toward first leg top end <NUM> can be balanced with the width of table top <NUM> to assure table <NUM> remains stable. The center of gravity in relation to the leg top ends <NUM>, <NUM> and the leg bottom ends <NUM>, <NUM> and the weight of table top <NUM> can be selected for optimum stability.

<FIG> show an illustrative release mechanism for the telescoping legs. <FIG> depicts leg release button <NUM> positioned on a foot <NUM> attached to leg extension section <NUM>. Foot <NUM> may be perpendicular to leg extension section <NUM>. Other positions of leg release button <NUM> are possible, provided a user can readily depress the button and it can engage/disengage the leg sections. <FIG> shows leg extension section <NUM> fully nested in sleeve <NUM>. 15C shows extension <NUM> partially withdrawn from sleeve <NUM>, while leg release button <NUM> is depressed. Extension <NUM> may be withdrawn from sleeve <NUM> to a length necessary to provide the desired table height. Each of legs <NUM>, <NUM> (see <FIG>, for example) may have a release button for withdrawing the leg extension from the sleeve. Integrating release button <NUM> into the leg foot to actuate the associated telescoping leg lock mechanism, such as shown in <FIG>, may provide an ergonomic configuration.

<FIG> depict an example of an illustrative stop <NUM> that forms not part of the present invention. The stop <NUM> may also referred to as a range limiter, attached to leg top end <NUM> of sleeve <NUM> for a coffee table height, for example. <FIG> shows a two-way spring-loaded plunger <NUM> positioned at the end of leg <NUM> for engagement with stop component <NUM>. Stop component <NUM> is affixed to the bottom of a table top <NUM>. When leg <NUM> is in a storage position, plunger <NUM> is pushed outward preventing table leg <NUM> from opening too far, i.e. from expanding to a height beyond a particular height, such as a coffee table height. <FIG> shows a cross-section of the plunger mechanism. Two springs are arranged in the mechanism with different forces or strengths associated with them. For simplicity, they will be referred to as a heavy spring <NUM> and a light spring <NUM>, although these are used only as relative terms. Heavy spring <NUM> is implemented to add compliance to the system. As shown, the extension section of leg <NUM> pushes against heavy spring <NUM> when the table is collapsed, thereby pushing plunger <NUM> outward. Light spring <NUM> keeps plunger <NUM> withdrawn when leg <NUM> is extended. By limiting the position of leg <NUM> with respect to table top <NUM>, a tendency for the table to tip when the legs are extended can be reduced or eliminated.

<FIG> depicts an example of a range limiter <NUM> of the present invention. Illustrative range limiter <NUM> includes a lock housing <NUM> that may be disposed, for example, toward or at the leg top end <NUM> of sleeve <NUM>. Lock housing <NUM> has a forked component <NUM> with ramped ends <NUM>. Ramped ends <NUM> engage a pin <NUM>. Pin <NUM> is disposed through a latch <NUM>. Pin <NUM> may be integral with latch <NUM> or attached in a manner other than being disposed through latch <NUM>. Pin <NUM> may also consist of two pins. Pin <NUM> and latch <NUM> may also be a single combined part. Latch <NUM> is biased clockwise about pivot <NUM> by torsion spring <NUM>.

As shown in <FIG>, as the table leg is collapsed, ramped ends <NUM> engage pin <NUM>, forcing latch <NUM> to rotate counter clockwise about pivot <NUM> into a locked position. When the table leg is fully collapsed, pin <NUM> rests on a flat section <NUM> of forked component <NUM>, preventing any force applied to latch <NUM> from being transferred to the inner leg in the direction of movement of the inner leg.

<FIG> depicts latch <NUM> biased by torsion spring <NUM> in a clockwise direction. Latch torsion spring <NUM> rests against an inner wall of a leg end cap <NUM> ("limiter housing"). Forked component <NUM> is shown displaced from leg end cap <NUM>. Ramped ends <NUM> of forked component <NUM> have not yet engaged pin <NUM>.

<FIG> shows ramped ends <NUM> of fork component <NUM> engaged with ramped ends <NUM> of forked component <NUM>. Ramped ends <NUM> have reached their excursion limit at the bottom of leg end cap <NUM>. Once the leg has collapsed fully, latch <NUM> can only apply force to the inner leg perpendicular to the direction of movement of the inner leg. This is relevant when latch <NUM> hits a stop component (<NUM>) on the underside of the table top, because at that moment, the force from the gas spring (which is trying to raise the table) is being transferred through the latch. Because the resultant load applied by latch <NUM> onto lock housing <NUM> is perpendicular to the telescoping direction, latch <NUM> should not cause the telescoping lock mechanism to bind. In other words, the telescoping lock mechanism can function normally because latch <NUM> is unable to apply a load to the end cap <NUM> in a way that might cause the lock mechanism to bind.

<FIG> show two positions of latch <NUM>. In <FIG>, ramped ends <NUM> have not engaged pin <NUM> so latch <NUM> is extended a maximum amount from the leg. In <FIG>, ramped ends <NUM> are fully engaged with pin <NUM> so latch <NUM> is rotated out of the way as the leg moves backwards over a limiter stop component.

<FIG> depicts illustrative parts of the range limiter assembly according to present invention. The parts include stop <NUM>, which is affixed to the underside of the table top, torsion spring <NUM> to bias latch <NUM>, latch <NUM> which is connected to the extension section <NUM> of the second leg <NUM>, pin <NUM>, which is disposed through latch <NUM> and torsion spring <NUM>, lock housing <NUM> and leg end cap <NUM>.

<FIG> depicts components to simplify range limiter assembly. A push out mandrel <NUM> and an assembly pin <NUM> are fixtures used for holding latch <NUM> and torsion spring <NUM> in place while the subassembly is fitted onto leg top end <NUM> of sleeve <NUM> and attached to the table.

<FIG> depict operation of a limiter assembly according to present invention. <FIG> depicts a side view of a table <NUM> with its top side down. <FIG> depicts close-ups of limiter assembly during operation. <FIG> shows a limiter assembly approaching stop <NUM> in the direction of arrow <NUM>. <FIG> shows latch <NUM> contacting stop <NUM>. <FIG> depicts limiter operation as extension section <NUM> of second leg <NUM> extends from sleeve section <NUM>. As extension section <NUM> extends from sleeve section <NUM>, latch <NUM> rotates clockwise (as viewed in <FIG>) out of the way of stop <NUM>. <FIG> shows further progression of the limiter assembly as extension section <NUM> extends further from sleeve section <NUM>, resulting in latch <NUM> being completely open. <FIG> shows operation of the limiter assembly as extension section <NUM> becomes further extended from sleeve section <NUM>, which rotates latch <NUM> further clockwise to an open position, allowing latch <NUM> to pass over stop <NUM>.
