Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a folding table comprising a substantially flat Cheedel surface exhibiting a rectangular profile and four collapsible legs that can be easily folded against the underside of the table surface. Concerning a table or similar collapsible structure.

The present invention relates to a folding table or similar structure having a generally flat table surface supported on the floor by means of a plurality of legs and a cable tensioning mechanism, the legs extending from the edge of the table. The legs are positioned at intervals on the inside and are connected to the bottom of the table surface in 19. The cable tensioning mechanism connects the lower ends of the legs to each other and connects the lower ends of the legs positioned below the cable surface to each corner of the table surface. a folding table or folding table extending upwardly into the vicinity of the folding table and having a cable tensioning mechanism configured such that when assembled, all cables are biased in tension and one leg is placed in compression; The purpose is to provide a structure similar to .

According to another aspect of the invention, a folding table or similar structure has a substantially flat solid table surface and two pairs of surfaces extending downwardly from the underside of the table surface. a support leg and a pair of legs articulated to the underside of the table surface at spaced locations such that the table presents a symmetrical shape when the pair of legs is upright; The vertices of the legs are limited to an inverted V shape, and the ends of the legs on the side away from the jointed vertices are connected to each other, and the ends of the legs are erected by the table. When the cable tension mechanism is in the tensioned state, the cable tensioning mechanism is fixed to the underside of the table surface so as to place the outwardly spread legs in the compressed state, and the cable tension mechanism is connected to the vertices connected to each joint. and separate tensile force applying means.

According to another embodiment of the present invention, the folding table has a substantially flat and sturdy table surface that is removably supported, and a folding table that hangs from the underside of the table approximately midway between the table surface and the floor. Positioned in the right place 2
The legs have two joint points and a pair of upper and lower legs that extend outward in the shape of a figure 7 extending from each joint point, and the ends of the lower legs sit on the floor, while the upper the ends of the legs support the cheedel surface, a transverse bar extending approximately parallel to the table surface between the points of articulation, a lower cable connecting the lower ends of said legs to each other, and a lower A rising cable extending from the lower end of the leg to the upper end of the upper leg, an upper cable connecting the upper ends of the legs to each other, and a tensile force applying/releasing means for biasing the cable to a tensile force applied state. In the erected state, all cables are biased in tension and the legs are in compression.

According to another aspect of the invention, a folding structure adapted for use as a camping table or bed comprises a generally rectangular chisel surface made of a flexible material and a folding structure erected. When installed, it has two articulation points positioned at appropriate locations below the table surface, approximately at the point between the table surface and the ground, and a letter 7 shape extending from the articulation points. The upper and lower legs are spread outward, and the ends of the lower legs are seated on the ground, while the ends of the upper legs are engaged with the table surface, and the points of articulation are a horizontal bar extending substantially parallel to the table surface between the legs, and a lower cable connecting the lower ends of the legs to each other;
A rising cable extending from the lower end of the lower leg to the upper end of the upper leg, an upper cable connecting the upper ends to each other, and a tensile force applying and angle removing means for biasing the cable into a tensile state. In the erect position, all the cables are energized in tension, and the table surface is stretched out between the upper ends of the upper pair of legs.

In one embodiment of the invention, when tension is applied, the lower part of the cable tensioning mechanism forms a flat support and the weight of the cable is supported by the cable, resulting in a loss of stability. The table structure can be placed on soft or sandy ground without any problems. When the tension applying means is released, the table can be folded by placing the legs on the underside of the table surface. In the folded state, the table structure can be stored in a flat state with little space.

The elements of the table support structure are configured to prevent twisting, tilting, and upward movement of the table surface by forming a triangular profile between the column, the table surface, and the tension member. has been done. In order to ensure that the cheedel surface remains stable for long periods of time despite slight changes in the length of the tensioning means due to creep or temperature changes, the cable tension gripping structure f spring elements must be tightened. Must be. In one embodiment of the invention, a coil spring is arranged in the vicinity of the prestressing means.

The spring can be placed anywhere on the table support structure. In another embodiment of the invention, 1
The curved table surface itself acts as a spring, and in a further embodiment a portion of the support element acts as a spring.

One of the features of this Tights 0 Chidel structure is.

The table structure can be easily and compactly dismantled and stored or transported. The table structure can be dismantled by releasing the prestressing device, loosening the tensile force applying element, and moving the leg or support from the normal position to the flat position against the table surface. For the same reason, the flexible tensile force applying portion may be moved to a flat position in contact with the Chidel surface.

The present invention will now be described in detail with reference to the accompanying drawings, which illustrate the invention.

First, referring to Figures 1 and 2 of the accompanying drawings, the folding table according to the present invention has a substantially flat table surface 10. In the illustrated embodiment, the cheedel surface is designed to be rectangular, but the table surface may also be circular or square.

Alternatively, a circular shape is also acceptable.

The table surface 10 is made of plywood, laminated wood or laminated plastic, fiberglass, glass, copper, etc., which can withstand a pre-applied warp,
It is made of a material with sufficient strength so that it will not break when it is bent against the pre-applied curvature by applying tension with the cable.

The ends of the table top are each supported by a pair of legs or posts 11 extending over the outer claws, the pairs of legs or posts 11 meeting at an upper articulation point 12.

Preferably, the joint point 12 is located at a distance 11i1F equal to about 1/6 of the total length of the table surface, which is within the narrow end of the table.

The lower ends 13 of the legs 11 are seated on the floor. All four legs of the table are made in a round shape. The legs 11 are made from steel pipes with a length of approximately 838 mm (36 inches), and when they are erected, the height of the table from the floor is:
Usually, it is preferable to design it so that it has 7 rows and 7 rows (29 inches).

The lower ends 13 of the legs 11 are connected to each other via a double Y-shaped cable tensioner $f'i. The medium heat of the double Y [1] extends below and along the longitudinal axis of the table surface in contact with the floor.
The ends of each have a short point 14a at the point 14a.
The end cable 15 is further connected to the lower end of the table leg 13 in a suitable manner. A junction point i4a between the cables 14 and 15 forming a Y is located directly below the joint point 12. The shorter cable 15 is also in contact with the floor and extends along approximately the same plane as the central cable 14. Five surfaces located below this extend approximately parallel to the table surface.

The modified t7/! shown in FIG. In this embodiment, the lower tensioning mechanism of the cable 18 has a rectangular shape and extends between the lower ends of the four legs of the table.

The stand is completed by the use of a vertical cable 16 running from each corner 11 of the table surface to the lower end 13 of the corresponding table leg 110. The vertical cable 16 may be connected to the short end cable 15 to form a single cable and inserted into a suitable hole or ferrule provided at the bottom of the leg 11 at y;i+13. According to this S configuration, on the long side of the table, the legs 11 and the vertical cables 16 form four triangles at each corner of the table. On the other hand, another triangle is formed by the line extending from the corner IT of the table surface to the joint point 12 and the shorter side of the table.

The advantage of using a cable that joins the lower ends of the legs together by creating a double Y-shaped connection is that the person sitting on the chair can move their legs freely, and the cable does not get in the way of the chair legs. That's true. 21'-
The configuration shown in FIGS. 1 and 2 is suitable as a dining table. However, the same effect can be achieved by extending the lower cable 18 in the rectangular shape shown in FIG. This embodiment is suitable for use as a coffee table. The figure also shows that the space formed between the table surface 10, the lower cable 18 and the vertical cable 16 defines a parallelepiped or brick-like space, which strengthens the overall structure of the table. It clearly illustrates what you can do to improve your performance.

The cable is placed in tension using a prestressing device made in the form of a turnbuckle 25 and spring means 26. This spring means serves to compensate for slight changes in the length of the tension cable which occur due to creep phenomena or temperature changes. In the embodiment shown in FIGS. , a spring 26 is disposed in the central portion 14 in the vicinity of a turnbuckle 25 or other prestressing means 25 .

However, the spring means may be provided anywhere along the tension cable, or if the cable is comprised of multiple sections, multiple spring means may be used.

If the table surface is curved in advance and the narrower end 10a rises upward without being stressed, apply tension to the cape /l/ as described above. The use of spring elements can be omitted since it is sufficient to provide

While the cable is in tension, the two legs 11 are in compression and function as supports. When you stress,
The triangles formed at the corners of the table by the legs 11 and the vertical cables 16 provide great rigidity to the entire table structure, thereby preventing it from twisting or tipping.

In the embodiment shown in FIG. 1, the use of a turnbuckle 25 or a quick tension release device (such as a pelican hook) allows the prestressing device to quickly release the tensioning condition γ6. can be removed. This quick release mechanism may utilize a lever action such as that found in ski bindings. By releasing the prestressing device, the tensioning element is in a relaxed state (as shown in FIG. 4), and the leg is moved from its normal use position I4 to the position in which the leg rests flat on the table 10. You can move your legs up to 1jij. The table is then transported to another location and stored, but since it is folded, it occupies very little space.

In the configuration shown in FIGS. 6 and 4.

The upper ends of the legs of the table are adapted to meet at a bin joint 19 located at the outer ends of the slats 20 and 20a, and the slats 2o and 20a are joined by a hinge 2.
Because it is joined from IK.

The bin joint 19 can be slid.

The inner ends of the slats 20 and 20a are movably joined to each other by a hinge 21. The slides 20 and 20a are adapted to move within a U-shaped guide 22 fixed to the underside of the table surface, as shown in FIG.

As shown in FIGS. 4 and 5, the upper end of the table leg is lifted by manually pushing up the bidirectional VC hinge 21 in the direction of arrow 23 toward the lower end of the table surface. It is easy to understand that they will move apart from each other at will. "The vertical cable 16 and the lower cable tension structure 14 and 15 or 1
8 can be placed in a slightly tensioned state.

To fold the table, the procedure is reversed, but the only operation required to release the tension on the cheedel is to manually move the hinge 21 downwards. It's nothing more than that. A simple catch or latch (not shown) may be provided on the underside of the cheedel surface to hold the slats 20 and 20a in the upper position. Another preferred method is to bring the loaded hinge 21 into contact with the underside of the table surface above the horizontal plane of the hinge 21', as shown in FIG. Using a center hinge.

When the table surface 10 is not in tension, the table surface may be in an upwardly curved state, or the edges of the table surface may be located at a higher position than the center of the table surface to form a concave surface. As shown by the dashed lines in Figures 1 and 6, the 10x warpage is negligible, and for a Cider length of 1829 rnm (6 feet), 25
．． Anything over 4 inches (1 inch) or 50.8 meters (2 inches) is good. However, in the above-described configuration, when a tension is applied to the vertical cable 16, the table surface bends in the opposite direction, so that after the tension is applied to the table surface, the table surface becomes almost flat along the horizontal plane. . The spring 26 can be omitted since changes in cable length due to temperature changes or wear can be accommodated by the camber described above.

Another way to move the joint points apart is to move them freely.

Use a bottle joint 19 (to join the upper ends of the legs that are spread outward) in a slide with an internal thread adapted to move in a U-shaped guide attached to the underside of the table surface. That's true. A male thread is provided at the end.
A spindle is attached to the slide. The end of the spindle is of square design and is adapted to engage via a crank (not shown).

Next, in the modification shown in FIG. 7, the table surface 10' is adapted to sit on a column frame arrangement constituted by cables and columns. In this example configuration, all stresses and strains are carried by the support frame. Therefore, it is permissible to make the table surface 10' from plate glass, marble or other brittle materials.

The support frame mechanism has two points of articulation 12',
The joint point 12' is located below the lower side of the table surface, approximately in the middle between the table surface and the floor surface.The joint point 12' is approximately 1/6 of the total length of the table.
It is located at a distance equal to , from the narrow end of the daple surface into the center.

Two pairs of outwardly opening legs' or struts 11a% 11bs 11C% 11d extending in a V-shape extend from each articulation point. Legs 11a and 11b form the lower pair and extend from the articulation point towards the floor.

Posts 11C and 11d form an upper pair.

The ends of the upper struts form support structures 31 that support the table surface 10' at each end of the table. Joint point 1
2' is supported by a horizontally extending bar 32 just below the long sleeve on the table surface.

The length and angular arrangement of the lower legs or columns 11C and 11d are such that the horizontal par 32 can occupy a position closer to the underside of the table than to the floor. Modifications based on aesthetic or structural considerations are of no use; however, such modifications are unlikely to affect the fundamental stability and function of the support structure.

The upper free ends 31 of the legs or columns 11C and 11d are connected by an upper cable 35 which extends straight in a substantially rectangular profile parallel to the table surface.

The lower legs or struts 1ia and 11b+ (r) have lower end corners 36 seated on the floor which are cable tensioners in the form of a double Y similar to the tension cables described with reference to FIGS. 1 and 2. The lower cable tensioning mechanism may alternatively be formed in the rectangular profile shown in FIG. 6.

The upper end 31 and lower end 36 of the leg or column are connected by vertical cables 6'
connected by. The cable is passed through a large ferrule or groove at the end of the leg. The cables 14', 15', 164, and 35 pass through the ends 31 and 36 through various routes, but it is easy for the designer to determine all of these routes. .

In the embodiment shown in FIG. 1, the quick tension release and quick tension application device 25' is positioned at a suitable location within the cable tensioning mechanism, preferably on the central cable 14'. ing. A spring 26 may be attached to the central cable to take up any slack in the cable, but this is not necessary.

A disadvantage associated with the tlit configuration shown in FIG. 7 is that when a large load is applied to the center of the table surface 10', the table surface 10' will deflect downward or the table will tilt sideways. This is a trend. In order to overcome this drawback, in the embodiment shown in FIG.
A pair of pillars 38 and 39 in the form of a letter is additionally connected to the pillars 11& and 11'o.

The upper bends or outer ends of the struts 38 and 39 are connected at a point 42 to the end of the strut rising upwardly from the other articulation point. An upper cable 35 extending along the long side of the table is adapted to pass through a hole provided in the abutment of the upper end of the column and pass through point 42. It has an inverted triangular shape with a lower apex 44, and is used for cables 43a, 43b, and 43c' connected to triangular ground cable mechanisms 45a, 45b, and 45C extending through the lower ends of columns 11a and 11b. This completes the assembly.

If configured as described above, 6 cables 43C and 4
3b, 45a, 45b, 45a' and 45 b' rJ,
jl, preferably about 10102i about 4 inches above floor level. In the second embodiment, even if the load is applied to the center of the table surface along a line passing through the cable junction 42, the support 38.39 and the triangular cable tensioning mechanism connected to the support 38.39 resists and counteracts the tendency to tilt the support structure from its original position.

In the embodiment shown in FIG. 8, it is divided into two horizontally extending pipe sections 32a and 32b, one of which slides into the other. 1. A spring catch or umbrella snap 46 is attached to both pipe pieces 32a.
The function is to hold it at the required interval of 32 bt.

The collapsible support structure shown in FIGS. 9 and 10 uses a generally rectangular canvas surface 50 with struts 11c extending upwardly from each articulation point.
, 11a', 38.39. , the term 'canvas surface' may include any suitable fabric or other suitable sheet material.Thus, the canvas surface 50 has the supporting function of the table surface and the Also serves as a puller for the upper cable 35 in the embodiment shown in the figure (iii
I'm getting better. Tensile '! 50 canvases based on aspirations
The edge (has a substantially flat shape as shown in FIG. 9).

A quick tension release device 51 is positioned near one end of a lower cable 52 that connects the entire lower ends of lower legs 11a and 11b. The lower cable 52 may extend in a double Y configuration as shown in FIG. 7, or it may have a rectangular profile as shown in FIG. The struts and cables may be arranged to take on the profile shown in FIG. 8, but in this case the canvas surface 50 itself serves as the upper horizontal cable. .

The arrangement of the legs or struts is similar to that of the embodiment shown in FIG. It is designed to slide in a pre-prepared manner and is fixed with a Western umbrella snap 55.

When folding up the entire structure, the quick tensile force release device 51 and the umbrella snap 55 are released from the locked state. The legs are folded freely, facing each other. The upper support is
9. Does not require uncoupling with the canvas folded between the legs as shown in FIG. The folded bundle, not shown in Figure 9, occupies only about 2 percent of the space the structure occupies when in its erected state.

The structure shown in Figures 9 and 10 occupies very little space and can be used as a camp bed, or it can be carried upright and used as a tent. In addition to being used as a part of the vehicle, it can also be used as a rainwater extractor or for other purposes. .

As mentioned above, the articulation points are generally constructed in the form of hinges or pivot joints. As illustrated in FIG. You can make these joints. .

The joint according to this embodiment consists of a central member 60 having a number of integral stubs 62;
- The 11clt is removably inserted into the upper part of the support from the support 11a. Therefore, the "joint joints 11j1" used in this specification include not only movable joints but also fixed joints.

In the embodiment shown in FIGS. 12 and 16,
The legs 111 extend downward from the bottom side of the table surface 110.The legs 111 are arranged in pairs at opposite ends of the table, and are arranged in the length direction of the table. It is articulated to the table surface at a position 112 extending inward from the short side of the table surface on a center line extending from the short side of the table surface. In the illustrated embodiment, each pair of legs is opposite
It is a single piece in the form of a letter, the apex of which is articulated with the table surface and the opposite end forming the foot of the leg. These legs are interconnected by a cable tensioning mechanism in the form of a double Y in a manner similar to the embodiment shown in FIG. To make such an interconnection, the central member 114 of the Y-shaped cable tensioning mechanism is brought into contact with the floor surface, and the short end cables 115 are further anchored to each corner of the table surface. extending upward as a vertical cable line.

When the table members are assembled into the operating condition shown in FIGS. 12 and 16, the foot ends of the table legs will rest beneath the corners of the table surface, and the cables will The tension mechanism can provide the required rigidity and stability to the table. .

Figures 18 and 19 show cables 115 and 116 extending through the foot ends of table legs 111.
Jj f is enlarged and illustrated/ζ.

Kädel'ff: To extend the table, each leg of the table is bent outwards at the foot end and rests on or extends parallel to the floor or other resting surface. , the outer edge of the foot is bent upward. The cable 115 is inserted through the hole provided in the leg, and
It passes through the distal end of the leg and extends upwards to rest on the corner of the table surface.

If necessary, the slide clamp 100 may be snap-fitted into legs extending parallel to the floor or other supporting surface.

Instead of attaching the tensioning device to the cable pulling mechanism, the entire tensioning device 150 may be used to articulate the apex of each pair of legs on the underside of the table surface.

This single reference 9. is illustrated in detail in Figures 11116 and 17. In the lt force applying device, a pair of legs 1110
A metal band 151 is wound in a loop around the apex portion, and the ends of the metal band 151 are fixed using a hard bolt such as a rivet 152, for example. Obikin 15
1, a groove 153 extending across the width of the strap.
is provided and is adapted to engage with the worm 154 capable of rotation T=J. Worm 154 engages groove 153 and is rotatably housed within a case 155 formed at the end of a strip 156 made of metal or other suitable durable material. The strip 156 rests against the underside of the table surface 110 and is secured by one or more setscrews 157 or other suitable means.

A keyway 158 is recessed in the head of the worm 154. By turning the worm 154, the strap 151 is pulled in the length direction along the lower side of the table surface, and
It will be readily appreciated that this allows the required tension to be applied to the legs and cable tensioning mechanism.

14 and 15 illustrate modifications of the embodiment shown in FIGS. 12 and 16. 14 and 15 show a table surface 110' having an elongated rectangular shape, with legs 111' extending from the table surface 110'.
0' is articulated to the underside of said table surface 110' by a turn 9 referenced 112'. 12th
16 and 17 and illustrated in detail in FIGS. 16 and 17.
It is articulated to the underside of 0'.

A cable tensioning mechanism is used, and in this embodiment the cable tensioning mechanism is connected to the oppositely positioned legs 11.
A cable 115a is provided to connect the leg ends of the legs 1' to each other.

Similarly, in the embodiment shown in FIGS. 12 and 16, the cable extends upwardly through the legs and is anchored to the table surface. In contrast to the embodiment shown in the figures, the upwardly extending cable portion 116'1-1. is not a single cable, but branches out from the foot end of the leg and is spaced apart. Extended to the fixed anchoring point 117 2
Consists of cables. Note that the attachment point 117 is positioned at an appropriate location spaced apart from the corner of the table surface. As described above, the triangular contour formed by the two cables extending upward from the end of the leg provides rigidity to resist rotational deformation of the rectangular table. and stability can be increased.

As mentioned above, the tensioning device ti 150' can be used to apply the required tension to the cable tensioning mechanism consisting of 115a and 116a. By operating the selective adjustment device 150, 150', the table surface 11 can be adjusted even when the foot end of the leg is seated on an uneven floor surface.
0.110' can be installed flat.

In most of the embodiments described above, the foot end of the table is positioned directly below the corner of the table surface. However, it is not always positioned like this. 14 and 15 show the case where the foot ends of the legs are not located directly below the corners of the table surface.
