Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to a collapsible shed system that utilizes a pair of collapsible frame systems that support a pair of panels located at opposite ends of the shed.

More specifically, the structure of the present invention provides an improved durable end frame that is collapsible, allows the frame to be easily erected, and maintains a stable condition when the frame is erected. It is.

The strut is a telescopic link mechanism (lazy-tong 5structure)
between adjacent outer vertices of the structure to add rigidity to the structure when erected and to facilitate folding whenever desired.

In the past, collapsible shed systems have been proposed and shown utilizing a pair of collapsible frame systems at opposite ends.

In some instances, telescoping linkages have been proposed and utilized for this purpose.

However, generally speaking, although telescopic link mechanisms are easy to erect, their range of use is extremely limited.

That is, two important problems arise.

The first problem is ease of standing up, which is limited to collapsible sheds of relatively small size.

Other problems relate to the lack of stability in the presence of wind and other forces.

In the presence of abnormal external forces, conventional telescoping linkages become unstable and often tend to assume an abnormal shape, and may even fail or collapse.

The structure of the present invention is provided with devices that aid in erecting, resist inadvertent collapse in the same way, and provide a durable structure that is stable in the erect state to resist external forces.

In particular, the collapsible shed system of the present invention utilizes improved collapsible frame systems disposed at opposite ends thereof, such opposing frame systems being mirror images of each other. .

In this regard, a device is provided in which struts are provided at and between adjacent spaced outer vertices of the telescoping linkage, whereby the struts render the entire frame arrangement both rigid and durable. It is supposed to be done.

Furthermore, the inner apex is designed such that a pair of mutually adjacent links are connected together to form two right angles of substantially 180°, thereby further reinforcing the stiffness of the overall structure. When assembled, the frame system forms a durable truss system, which provides durability and stability to the entire shed.

By configuring the adjacent links at the inner apexes (indicated by reference numeral 102 in FIG. 4) to form substantially two right angles, these links form an arcuate shape of constant radius;
Forms a pattern that generally circumscribes a semicircle.

Inner vertices are defined as points where mutually adjacent links meet and are joined together.

Still other features include means for coupling or linking the struts together for simultaneous or sequential disengagement of the struts, thereby facilitating collapsing of the shed structure whenever desired. It is supposed to be done.

In some cases, the above-described release devices may be interlocked together to allow one operator to simultaneously release the struts from the two collapsible frame devices at opposite ends of the collapsible shed structure. Eggplant is preferable.

A feature that facilitates the folding of panels supported by opposing frames is that each panel is connected to the frame at the intersection of telescoping linkages, so that upon folding the inner apex of the folded member is tensioned. are arranged to form segments that

This arrangement facilitates storage without adversely affecting the panel fabric and contributes to a compact folded state of the overall structure.

SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an improved collapsible shed system that utilizes a pair of improved stabilizing and durable frame systems at opposite ends,
The device is designed to remain in an upright position and is further designed to provide ease of raising and folding whenever desired.

Still another object of the present invention is to utilize a telescoping linkage for a collapsible frame device and further utilize struts between the outer vertices of the telescoping linkage so that the strut device facilitates folding of the shed. Therefore, it is an object of the present invention to provide an improved collapsible shed device which can be simultaneously disengaged or removed from an upright position whenever desired.

Still another object of the invention is to utilize a telescoping linkage at both ends to assist in initially erecting the telescoping linkage;
It is an object of the present invention to provide an improved collapsible shed device which is then provided with a mechanical restraint device to hold the frame device in an upright position.

Still another object of the invention is to provide an end frame of a collapsible structure in the form of repeating links, the inner vertices of the set of links extending substantially 180° between adjacent links in the erect state. and a strut arrangement is provided between adjacent outer vertices of the set of links to improve and maintain the stability of the structure when erected.

Yet another object of the invention is to provide a series of shed panels,
It is an object of the present invention to provide an improved collapsible shed device in which these panels are connected to the inner portion of the telescoping linkage, thereby facilitating storage and facilitating folding of the structure for storage purposes.

Other objects of the invention will become apparent to those skilled in the art from the following description, claims, and accompanying drawings.

In accordance with a preferred embodiment of the invention, and with particular attention to FIG. It includes a pair of collapsible frame assemblies adapted to support a number of panels, such as panels 13 and 14, extending therebetween.

As is clear from the drawings, each telescopic link mechanism (lazy-tong 5
The collapsible frame devices 11 and 12 in the form of a structure form the actual structural arrangement of the end frames.
are mirror images of each other.

Figure 1 shows this structure in an upright position, but Figures 2 and 3
The figures show the folded and half-erected states, respectively.

As is clear from Fig. 2, the foldable shed device 1
0 is shown in a collapsed configuration suitable for storage, with rigid side panels 16 and 17 providing some protection for flexible panels such as panels 13 and 14 during storage. used.

Panels 16 and 17 are also rigid and durable and form a device that protects the structure from damage caused by foot kicks, hard object strikes, or other obstacles typical of these types of structures. ing.

As will be appreciated, the structure of the present invention can form a portable folding shed of any length.

'However, the practical limit to the length of a shed is typically the weight of the overall structure, and is also limited by wind forces and the like, which become important when significantly longer structures are utilized.

In practice, therefore, if a long construction is desired, a number of individual shed units are arranged end to end as the required length is reached.

The end panels can be used as additional protection from other members (not shown).

Typically such end panels are zippered.
per), button, snap (5nap), rotary joint (
5w1vel) or other such conventional fixing devices to the frame 11 or 12.

The end panels are watertight and configured to resist accumulation or accumulation of water, snow, ice, or the like.

As for typical construction materials, the collapsible frame assembly can be made from lightweight, durable aluminum tubing, although fiberglass rods can also be used, and panels 13 and 14 are made of nylon, polyethylene terephthalate (Dacron). Preferably, it is made from a durable material such as or the like.

Side panels 16 and 17 are typically made from fiberglass or the like, although all such materials are, of course, commercially available.

When fiberglass is utilized as the material for panels such as panels 16 and 1T, these panels are preferably corrugated to add stiffness to the overall structure.

Although either vertical or horizontal waveforms can be used, vertical waveforms are generally preferred.

4-7, the frame apparatus is shown in a substantially upright position.

As shown (the collapsible frame device is
and a second interconnected linkage assembly, the strut assemblies forming alternating inwardly and outwardly located structural spans in the upright position.

More specifically, in Figure 4, the inner span is 20
and 21, and the outwardly located spans are 22 and 2
3.

Also, as is clear from Figure 4, the span located outward is 25.
and spaced vertices such as at 26, these spaced vertices being bridged by struts such as at 27.

As is clear from the illustration in FIG. 7, for example, the strut 2
Individual struts such as 7 and 28 each have apex 25
and 26, thus allowing the struts to be pulled inwardly against a pressing force to facilitate disassembly of the assembly, as detailed below. That's what I'm saying.

However, in the upright position as shown in FIG. 4, the individual struts bridging the outwardly spaced vertices provide significant stability and stiffness to the upright structure.

5 and 6, the link assemblies forming the internally located structural spans are shown at 29 and 30.

Link assemblies 29 and 30 are pivotally connected by a hub or sleeve 31 in the manner of a typical telescoping linkage, with link portions 29A and 30 extending outwardly relative to outwardly located apexes 25 and 26, respectively. It extends outward as 30A.

The top of link portion 30A is shown broken away to show details of cradle member 35, which will be discussed in more detail below.

As is clear from the illustration in FIG.
2 extends the entire length of the collapsible frame arrangement and is connected by a pulley 33 to an outer strut, such as strut 27 (the particular function and details of this string are detailed in Figures 9, 10 and 11). It is shown).

The pulley 33 also shows arrow 3 when tension is applied to the lacing device.
4 is used to apply an inwardly directed force to the struts 27 in the direction of 4.

Such a tensile force provides a tilting force to the device as described above.

One link making up the linkage is shown at 35 and has a passageway formed therein for receiving a strut, as particularly shown in FIG.

This strut receiving passage is indicated at 36, and the crossover stop is indicated at 36A, with the strut 27 shown disposed therein.

Continuing to pay attention to FIGS. 5 and 6, link 35 is connected to pin 38.
It can be seen that the strut 27 is pivotally connected to the strut 27 by the arrow 34, thus allowing an arcuate movement of the strut 27 in the direction of the arrow 34.

As previously mentioned, the proximal end of strut 27 is pivoted within a hub formed at apex 26, specifically about pin 39.

It can also be seen that the individual link members 29 and 30 are pivoted together by a pin 40 which is also located within the hub 41.

Hub 41 serves the purpose of a base member for holding panels such as textile panels 13A and 14A.

The method of supporting this fabric hook will be described later, but here we use a tie point 4 with a hook.
2 is used for this purpose.

With continued attention to FIGS. 5 and 6, it can be seen that link member 35 is provided with a slot 45 for receiving a pin.

This elongated hole 45 allows relative movement to occur between the individual struts and the base telescoping linkage during raising and folding, and the pin receiving area allows for relative movement to occur between the individual struts and the base telescoping linkage during raising and folding of the structure. This is necessary because the effective spacing, or actual distance, between vertices moves and changes.

This groove allows relative movement to occur to aid in easy disassembly of the device, while remaining rigid while the device is in the upright position.

While the collapsible shed of Figures 1-19 is in the upright position, the struts, such as struts 27, actually form compression-resistant struts between the individual vertices.

In the standing position and when there is no abnormal external force, strut 27
are separated from the contact surfaces of adjacent bubs by a distance of approximately 0.254 mm (approximately 0.0101 nch).

When there is an outward force applied to the structure, i.e. caused by wind blowing from both ends of the structure or by a person or object pushing outward on the inner surface of the panel, the struts 27 are designated by the reference numeral 27A.
The free end of the shed, due to its own weight, engages and strikes the surface of the bub 25A formed on the apex 25.

In the illustrated construction, loads beyond the normal loads due to the unique weight of this assembly applied to the exterior of the shed cause the apex 27A of the strut 27 to more firmly engage the surface of the bub 25A.

Under conditions where wind or other loads applied to the interior surface of the shed structure offset the normal loads due to the unique weight of the assembly, the apexes of the struts separate from the surface of the bub 25A.

Attention is now drawn to Figures 8.9.10 and 11, in which further details of the individual articulation connections are shown together with details of the operation of the lace system.

In particular, a torsion spring 50 is used to provide a constant pressing force on the strut 27 and the same corresponding strut device.

The torsion spring 50 is, for example, attached to the bub 25A and fixed to a pin or through shaft 51 (FIG. 12), and the pin 51 has a transverse pin 52 passing through it, and is inserted into a groove formed in the bub member 25B. is locked.

The torsional rotational force exerted on pin 52 by spring 50 can be controlled by a preload, and the barb of spring 50 is engaged in hole 54 formed in bub 25C.

It is usually desirable to place the spring 50 in tension to prevent the spring 50 from becoming stuck and thereby tightening against the pin.

A retaining ring is indicated at 55 and is adapted to hold pin 51 in place.

Two components 35A of link 35 with elongated holes 45
and 35B (see FIG. 9) are shown in FIG.

14 to protect the spring for ease of handling.
It is usually desirable to place a member on each spring similar to the tip or sleeve-like member 87 shown in the figures.

Continuing to look at FIGS. 9 and 10, the string 32 passes through a pulley 33, as specifically shown in FIG. Force is applied to strut 27.

Therefore, the force that pulls the string inward is the outer vertex 2
The individual struts 27 extending between the struts 5 and 26 are disengaged from the bub 25B.

Since the construction of each is identical to the other, it is not considered necessary to describe the operation in detail other than that the free ends of the laces 32 are attached to this structure as at 58 and 59.

Therefore, the force applied inward to the string 32 will cause it to collapse.
This provides a tendency to disengage each individual strut 27 as shown.

Instead of fixing the free end of the string 32 to the wall of the structure, the string 3
2 together with paired strings at opposite ends,
By pulling once, the force can be transmitted to the opposing string as well.

As mentioned above, since each repeating structural unit is identical to each other, it is sufficient to describe the mechanism for one span and there is no need to repeat the description.

It will also be seen that the frame members at each end of the structure are identical except that they are mirror images of each other.

12-19, further details of the construction of the end frame are shown.

As previously mentioned, FIG. 12 shows details of a spring-loaded mechanism for providing compression or pretensioning of individual struts extending between adjacent spaced outwardly located vertices.

FIG. 13 shows details of the construction of a typical internally located bub, such as bub 60.

The bubs 60 are spaced apart by a sleeve member 63.
Included in the bubble members 61 and 62.

A lace guide pin is positioned as at 64, and the lace 32 is positioned inwardly thereof as shown.

A torsion spring 65 is shown mounted on pin 66 and held by transverse pin 67 and hook 68.

As shown in the figure (the key part 68 is a hole 69 formed in the bub 62).
accepted within the country.

A second pin 70 passes through the diameter of pin 66 and holds the assembly together.

The amount of preload on the springs 65 is discrete and controlled to aid in the uprighting of the device and to resist sudden or uncontrolled collapsing.

The amount of force to be applied from an individual spring, such as spring 65, is determined by evaluating the weight of the entire collapsible shed structure.

Turning now to Figures 14.15 and 16, details of the panel tensioning system are shown.

In particular, panels such as panels 13 and 14 are
is supported by a spring biasing device as shown in FIG.

Reinforcement strips are provided at the ends as at 75, and tension is provided by sliding spring retainers.

A single purpose spring is provided at one end of the structure as shown at 76 and is held in place by a disc 77.

A spring 76 is also wound on the rod 78 and this door 8
is held entirely within a bubble, such as the bubble shown at 79.

Of course, this bub 79 is held at the opposite end of the structure, such as frame 12 of FIG.

The details of the bub 79 are, of course, generally the same as those of the opposing bub member designated 80.

A support hook 81 is provided for one end of the panel 13, and a reinforcing ring member 82 is attached to the panel 13.
It is used to distribute force.

Therefore, at the opposite end a reinforcing strip is provided as at 84,
This reinforcing strip also carries a reinforcing ring 85.

A second support hook is shown as at 86, which support hook is arranged to move with the droplet or sleeve-like member 87.

As shown, the hook 86 is received within a hole formed in a sleeve-like member 87 and is slidable within a groove 88 formed in a tubular support member, such as support member 90.

Support member 90 is one of many such support members extending between the respective inwardly located vertices as shown.

FIG. 15 shows details of the structure of the end of the cylindrical link portion 29A or 30A.

The end of the tube is provided with a diametric hole as shown at 91 in FIG.

For example, the individual tubular components (link assemblies 29 and 30) that extend across the vicinity of the individual restraint points formed by hooks 81 and 86 (where the panel is restrained by the hooks attached to the frame) It does not end at the aforementioned point of restraint.

Instead, tube sections, such as link section 29A, terminate in plastic bushings or bubs, such as at 92, to avoid exposing the open pointed end of the tube.

As shown more clearly in FIG. 16, the bubs 80 are spaced apart by sleeve members 96 and retaining discs 99 (
14) and includes two bub portions 94 and 95 mounted on a rod 98 which extends through and terminates therein.

Although retaining disc 99 is preferably positioned to slide within sleeve-like member 87, disc 99 can alternatively be positioned so that it is received within the restraints of the tubular structure.

The functionality of this arrangement has already been explained.

Also shown in FIG. 16 is an end panel 100 extending downwardly from the connection point formed by hook 86 (as shown).

The reinforcing strips shown in FIG. 16, such as reinforcing strip 84, may be modified in the shape of reinforcing strip 101 to form zipper member 1.
02 is accepted.

Zipper member 102 secures end panel 100 to reinforcing strip 101 as shown.

17-19, a folding device of this construction is shown.

In particular, these figures sequentially illustrate the condition of the panel, particularly the textile panel, as the structure is folded from an upright position.

The spacing of the individual cross members 90 relative to the panel engagement hooks is
The fabric panels are kept generally taut at all times, thus preventing tangling.

The lace device 32 is also adapted to be folded back and therefore kept taut in the folded position.

The configuration in which panels 13 and 14 are attached to the underside of the frame members (see FIG. 1) increases the ability of this structure to be folded.

Turning now to Figures 1, 2, 3 and 4, details of the base panel are shown.

Among other things, the base panel provides a rigid wall and a foundation upon which the rest of the semi-circular frame structure rests.

Although the use of rigid walls as described above is not essential,
Usually considered desirable.

As seen in FIGS. 1 and 4, base bub members 103 and 103A extend outwardly from rigid walls 16 and 17 and are secured to base pivot bubs 106 and 107 by links 104 and 105, respectively.

The outer vertices formed by bubs 103 and 103A are connected to base pivot bubs 110 and 111 by link members or support struts 108 and 109, respectively.

As already pointed out, the above-mentioned structure can be made from aluminum tubes, the sleeves, bubbles and other parts being made of molded polytetrafluoroethylene, nylon, formaldehyde-derived acetal resin (Delrin) or the like. Made of any suitable durable industrial plastic material such as those of.

Also, as previously indicated, the fabric used for the shed panels may be any suitable fabric such as woven nylon or the like.

To increase durability and improve resistance to elongation, textile fibers are laminated to the film to provide increased diagonal strength.

The lace material may also be a durable woven or knitted material made from nylon or similar materials.

The length of the cord is preferably chosen such that it is taut when the unit is folded, and this is made possible by the folded configuration of the structure.

DESCRIPTION OF THE SECOND PREFERRED EMBODIMENT According to the second preferred embodiment of the present invention, Nos. 20-27
Focusing on the embodiment shown in the Figures, the collapsible shed apparatus, designated generally at 120, has similar basic features as shown at 11 and 12 in the embodiment of Figures 1-19. The linkage forming the telescoping linkage is in a modified form in this case.

A second pivot post 132 is provided to complete the repeatable segment.

One such member 132 is shown on the left, and a second corresponding member 132A is shown on the right of FIG.

Support struts 132-132A are pivotally mounted within a pivot block assembly generally designated 134 and held in place by a latching ball and socket combination assembly generally designated 135 in FIG. is held in

Member 131 forms a strut arrangement, which is
It is functionally similar to the specific example shown in FIG. 9, but in a modified form.

Connector 131 thus provides a strut place pivot connection to links 126 and 127.

Particular attention is now drawn to FIGS. 21 and 24 for a description of the features and details of assemblies 134 and 135.

Specifically, assembly 134 utilizes central stud member 137 as a support pin and pivoting sleeve members 138 and 139.
are provided to support the rods 121 and 122A, and it is noted that the rods 121 and 122A are arranged in a linear or perpendicular relationship to each other.

The rod 12'lA is functionally the rod 121 in FIG.
, and rod 122A functionally corresponds to rod 122 in FIG.

Ball and socket arrangement 135 includes a ball member 140 connected directly to support post 132 and is provided with a pole receiving socket 141 .
41 is an angular extension of sleeve member 149, as will be described in detail below.

The stud member 142 is provided with a nut 143 as shown in the figure (for supporting and holding the rod receiving sleeves 144, 146 and 146, and washers 147 and 148 are provided).
It is designed to control the rising and folding of this structure and reduce the friction at that time.

A rod receiver sleeve member 144 is connected to one end of the rod 122, and a rod receiver sleeve member 145 also connects to one end of the rod 122.
It is connected to one end of 21A.

Sleeve 146 is connected to one end of link 126A, and sleeve portion 149 serves as a socket holding member and is connected to link 127.

Attention is directed to FIGS. 20 and 22 for a detailed description of the pivot and latching assembly, designated generally at 131.

The pivot and latching assembly includes a nylon sliding sleeve or block 151, which includes block member 15.
2, the block member has a blind hole 153 formed to receive the end of the post 130.

A pivot latch assembly is indicated generally at 154 and is attached to a pivot shaft 156.
It includes a latching dog member 155 which is pivoted about the block 152.

A compression spring 157 is provided within the bore 158 to permanently urge the latching dog 155 to the position shown in FIG.

Thumb pressure on latching dog 155 at point 159 releases the latching dog, allowing nylon block 151 to slide downwardly on post 130 as shown in phantom in FIG. .

Also, as shown in FIG.
60 is the receiving hole 1 of the roof boom or panel support member 162
61, which booms extend between opposing frame members and are used to support the fabric of the enclosure, with each boom 162 typically being curved outward to increase stiffness and provide water disposal. .

A set screw 163 is utilized to hold boom 162 in place within hole 161.

Hole 165 is used to receive post 130 as shown.

Block 160 is threaded as at 166 to receive a stud 167 therein.

Referring to FIG. 20, the pivotal connection of rods 121 and 122 is within sleeves 168 and 169, which are pivotally mounted on the shank portions of sleeve studs 167.

To erect the folded structure, reference is first made to FIG. 7, which shows the segments of the folded repeat structure in detail.

Specifically, the individual links are expanded until the arrangement shown in FIG. It is understood that these placement positions are common to both husband and wife, and the only difference is the physical placement.

The sliding members of block 151 are moved outward from the folded position to an intermediate position shown in phantom in FIG. 24, and finally in FIG. Continue moving in the opposite direction to the arrow shown in the middle.

Latch member 155 then engages the edge of sleeve or block 151 as shown in FIG. 22, securing ball and socket connection 135 in place in the configuration shown in FIGS. 20 and 21.

To disassemble this device, block 151 from the latching device.
Successive disengagements are performed in sequence until the device is completely folded.

Typically, the first actuation of each individual segment is the unlatching of the ball and socket connection 135.

In the embodiment of Figures 20-27, there is no need to use a cord or other type of disconnection device.

This is because the individual link assemblies are assembled in sequence.

Following a series of folding movements of the configuration shown in FIG. 26, and following an arcuate movement as indicated by arrows 171 and 172, a fully folded configuration is finally obtained as shown in FIG.

Figure 26 shows the repeating unit in a partially folded configuration, with arrows 171, 172 and 173 indicating the direction of movement of the individual members during the folding operation.

As can be seen, the link assembly includes a solid rod, such as rod 121, which meets rod 122A at pivot point 134.

In the adjacent link assemblies being connected, rod 122A is continuous and extends to a point where the end corresponds to rod 122B shown in FIG.

The embodiment shown in Figures 20-27 is easily adapted to construction using glass fiber rods and molded synthetic resin loft receiving members.

Conventional nylon or acetal resins (Delhine) obtained by polymerization of formaldehyde can be used for such parts.
