Description

TENT COMPRISING TWO SIDE MAT LINES AND ONE

COVER FABRIC FORMING DOUBLE CURVE

The present invention relates to a tent which can have a large volume.

It is known to make tents with a large volume, in particular for accommodation, shows or receptions, which can be installed on a ground or an enclosed space. These tents do not require a ground foundation, can be dismantled and reassembled in different places.

One type of known tent comprises one or more internal central poles arranged vertically, supporting a covering membrane, a plasticized fabric for example, which is taken up on lateral uprights receiving the outline of the covering. Side membranes can connect the side poles to close the edge of the tent. These tents can be rounded or rectangular.

In general, the membranes, hereinafter called fabrics, can be formed from any material, woven or non-woven.

The central masts are higher than the lateral masts in order to form a slope on the cover allowing the water to be evacuated around the contour.

The central masts constitute obstacles placed inside the tent which can hinder the installations or the interior passage.

Another known type of tent has only side poles, the upper ends of which are connected together by horizontal structures, in particular by triangular trusses providing a slope on each side of the cover.

This type of tent which can also be rounded or rectangular, has horizontal structures representing a fairly large mass, as well as an installation complexity for these structures installed at height, which require sufficient personnel and possibly lifting means for mounting.

It should be noted that an advantage of the tents is mobility, which includes transportation as well as simplified and rapid assembly and disassembly, with few staff, in order to facilitate transfers. The mass and volume of the folded tent must be reduced as much as possible.

In addition, the sides of the cover fabric descending around the perimeter of the tent to allow the evacuation of water, generally on the two long sides of a rectangular tent, oblige to form side panels which are not very Tops. The passage of light through these side panels is limited.

The object of the present invention is in particular to avoid these drawbacks of the prior art.

To this end, it offers a tent comprising lateral masts, and a cover canvas carried only by these lateral masts, remarkable in that the lateral masts are arranged in two spaced lines generally having a longitudinal direction, and in that the canvas of cover has two opposite longitudinal sides each supported by a line of lateral masts, and two other transverse sides each receiving a tension system towards the outside of the tent which is directed towards the ground.

An advantage of this tent is that without having internal central masts, one obtains a tension of the cover fabric between the two lines of lateral masts giving it in the transverse direction a first curvature turned downwards, and with the two other sides stretched towards the ground a second curvature in the longitudinal direction facing upwards, forming a gutter which allows water to be discharged towards the two longitudinal ends.

The absence of an internal mast gives off an important central space. In addition, the lateral sides of the cover canvas, fixed on the pole lines which can be straight or curved, constitute the highest points of this cover, which makes it possible to produce transparent side panels on the sides of the tent which can let in a lot of light.

In addition, tests have shown that the particular curvature of the cover fabric gives a very interesting acoustics which eliminates sound reverberations in the tent, which is particularly interesting for lowering the interior noise level when a large number of people are gathered at the inside.

The tent according to the invention may further include one or more of the following characteristics, which can be combined with one another.

In particular, the two lines of lateral masts can be straight and parallel.

Alternatively, at least one line of lateral masts is at least partly curved.

Advantageously, each line of lateral masts comprises an upper spar connecting the upper ends of these masts to one another. These upper beams give rigidity to the structure, and facilitate the attachment of the longitudinal sides of the cover fabric.

In addition, the cover fabric advantageously comprises on its longitudinal sides a continuous end bead fitting in a groove in the upper spar to be fixed therein. The bead makes it possible to apply continuous tension over the entire length of the side of the fabric, which facilitates installation, and avoids particular points of traction which can cause deformations.

Advantageously, each line of lateral masts comprises an intermediate spar disposed below the upper spar, connecting the masts together.

Advantageously, the tensioning system on each transverse side of the cover fabric comprises a single tensioner directed towards the ground. This simplifies the attachment of the tensioner to the ground with a single point.

In this case, advantageously each transverse side of the cover fabric forms a central point where the single tensioner is located. The central tip allows the traction forces coming from the single tensioner to be distributed evenly over the entire transverse side of the cover fabric.

Advantageously, the side masts are inclined towards the outside of the tent.

In this case, advantageously each lateral mast is supported by a vertical upright disposed on the outside of this mast. We realize a triangular structure with a strong resistance for the traction of the covering fabric directed inwards.

Advantageously, the base of the vertical upright is fixed to the outside edge of the tent floor.

Advantageously, the tent has open passages each forming the entire width between two side masts. These passages are easy to carry out, with a closure fabric which can be directly hooked on the profiles arranged on each side.

In addition, the tent may include a floor comprising a grid of side members and cross members, each cross member comprising at each end abutting a side member, a cleat sliding in a groove of this cross member to adjust its end in a groove of the member. A height setting of these two sections is made quickly and simply between them.

In addition, the tent may include a floor comprising panels placed on side members, each panel having cutouts each receiving a locking hook having under the panel a recess which adjusts on a hanging stud fixed on one side of a spar.

Advantageously, the tent comprises fabrics stretched transversely between the two lines, by connecting two lateral masts arranged opposite one another, at the ends or in the center of the tent.

Figures 1, 2, 3, 4 and 5 show a tent of rectangular shape, comprising a longitudinal direction arranged along its length, comprising a floor 2, and on each long side a line of side masts 4 inclined outwardly according to a angle of about 10 °.

The tent has symmetry along the longitudinal and transverse median axes. In general, the outer sides are defined as facing the outside of the tent.

Each lateral mast 4 comprising a base fixed a little inside the edge of the floor 2, and an upper end coming out of this floor, is supported at about three quarters of its height by a vertical upright 6 located at the edge of this floor.

On each side an upper spar 20 connects the upper end of the line of lateral masts 4, and an intermediate spar 22 arranged in parallel, connects on each side these masts a little above the connection with the vertical uprights 6.

A cover fabric 8 is stretched between the two upper side members 20, forming in the transverse direction a regular curvature turned downwards, presented in particular in the cross section of FIG. 3.

The lateral masts 4 inclined towards the outside, supported by the vertical uprights 6, have, by this inclination, good resistance to traction towards the inside caused by the transverse tension of the covering fabric 8.

In the longitudinal direction, each end of the cover fabric 8 forms a central point 10, connected to the longitudinal sides by a concave curvature, which is fixed by a tensioner to a point of attachment to the ground

12.

The longitudinal traction of each tensioner downwards, combined with the transverse tension on the cover fabric 8, gives this fabric in the longitudinal median plane a regular curvature turned upwards, presented in particular in the longitudinal section of FIG. 4 .

The double curvature of the cover fabric 8 gives it a uniformly distributed tension, avoiding folds or particular points of tension, unattractive and which can tire the canvas locally.

Note that the only two points of attachment to the ground of the tent are formed by the attachment points 12, which limits the effect of the installation of this tent on the ground.

Each longitudinal side of the tent has two openings 14 each disposed between two lateral masts 4, comprising an inclined plane placed on the ground to make up for the height of the floor 2, and a canopy 18 supported by two dives 16 inclined towards the outside.

The other spaces between two lateral masts 4 are closed by transparent fabrics stretched laterally between two vertical uprights 6, and in the upper part between two lateral masts 4, giving great brightness to the interior of the tent, in particular thanks to their height. important above the cover 8.

It will be noted that the openings 14 can be placed anywhere between two lateral masts 4, and that the transparent fabrics on the sides can be partially open or entirely removed, in particular for ventilation or in the event of significant heat.

The pitch of the tent is as follows. A grid of profiles is laid on the ground, formed of side members and crosspieces, receiving in each rectangle a floor panel.

Then fixed on each side the assemblies each formed by a lateral mast 4 and its vertical upright 6, which can be easily installed individually by a single man. These masts 4 are then connected with the longitudinal members 20, 22.

The long sides of the cover fabric 8 are then hung on each upper spar 20, without any particular tension. Finally, a final longitudinal tension is produced with the two points of attachment to the ground 12, which gives both the double curvature on the cover fabric 8 ensuring its tension in all directions, and its rigidity in particular to avoid any floating caused by strong winds.

Figures 6 to 10 show the mounting of the tent floor first comprising the production of braces formed by side members 30 and cross members 32 made of extruded aluminum alloy profiles, constituting a grid placed on the ground. Each rectangle of this grid receives a panel 54 placed on the profiles, these panels being adjusted together so as to form a smooth, slightly raised floor.

Figure 6 shows a spar 30 receiving on each side a cross member 32 disposed along a common axis of the cross members. The spar 30 has on each side a longitudinal central groove 34, two pins 36 indicating the point of alignment of the cross member 32, and two attachment studs 38 fixed above the central groove, symmetrically with respect to the cross member.

Each cross member 32 has on each side a longitudinal central groove 44, receiving at each end a sliding cleat made of aluminum 40.

A tab for tightening the cleat 42 fixed by two rivets in the central groove 44, presses elastically on this cleat to brake it by allowing longitudinal sliding. The end of the cleat 40 is adjusted before the assembly to the end of the cross-member 32.

Figure 7 shows the positioning of a cross member 32 on each side of the spar 30, these cross members each aligned with the pins 36 marked on the sides of the spar.

Then performs for each crosspiece 32 a sliding of the cleat 40 on each side, in order to insert its end into the central groove 34 of the spar 30. The cleat 40 held in this position by the clamping tongue 42, locks the height of the crosspieces 32 relative to the spar 30 in order to form a lower plane placed on the ground, and a regular upper plane receiving the panels.

One can also install an axis in the cleat 40 which slides in a hole in the cross member 32, in order to prevent the displacement of this cleat so that it cannot escape from the spar.

FIG. 8 presents a panel 54 comprising in each angle a cutout 56 elongated parallel to the side members 30, receiving a locking hook 50 formed by a folded sheet, comprising an upper horizontal part allowing gripping, and a vertical part comprising a hollow 52 turned towards the near crossing 32.

Each cutout 56 has a vertical slot receiving the vertical part of the hook 50, to guide it downward on the side of the spar 30, and an upper hollow of small thickness receiving the horizontal part of the hook in an adjusted manner in order to integrate it. '' obtain a panel top that remains smooth so as not to disturb users.

FIG. 9 shows the sliding of the panel 54 towards the cross-member 32, which engages on each side of this panel the hollow 52 of its hook 50 on a hooking stud 38 of the spar 30.

The attachment stud 38 has an end shoulder, the sheet metal of the hook 50 coming behind this shoulder which further secures the panel 54 on the beam 30 preventing lateral separation of this panel.

FIG. 10 shows the installation of several panels 54, the front panel being seen in transparency, its hook 50 being engaged on a hooking pad 38.

Each side mast 4 and vertical upright 6 is fixed by a connecting piece to a side member 30 or a cross member 32, in order to obtain good resistance of these bases.

Figures 11 and 12 show a first connecting piece 60 fixed on the outside of a side mast 4 and at the upper end of the vertical upright 6 supporting this mast, to make the inclined connection between these two profiles.

A second connecting piece 64 is fixed on the inner side of the lateral mast 4 and on an intermediate spar 22, to make the perpendicular connection between these two sections. Two flat reinforcing bars 62 fixed on each side of the vertical upright 6 to extend it upwards, have their upper ends fixed to the second connecting piece 64.

The connecting pieces 60, 64 and the reinforcement bars 62 are fastened in a simple and quick manner in the grooves of the profiles, which allows only these lengths to be cut to length without having to carry out additional machining.

We obtain a tent with simple and light elements, which can be easily assembled each by a single person.

The cover fabric 8 as well as the side fabrics are advantageously fixed to the profiles of the side members 20, the side masts 4 and the vertical uprights 6 by any type of attachment system and known tension. In particular, it is possible to produce a bead on these sides of canvas which fits in a groove of the profiles, with a system for blocking the bead in the groove engaged in the longitudinal direction of this groove, or in a lateral direction.

The cover fabric 8 having two inverted curvatures gives the tent a particular and modern aesthetic, allowing large transparent or open openings on the two long sides which gives a significant luminosity in the tent.

As a variant, it is possible to produce different forms of tent according to the invention, comprising in particular longitudinal sides constituting lines having any shape. In particular these lines can be curved, or straight and not parallel to make a tent of slightly trapezoidal shape. It is also possible to produce upper edges of the longitudinal sides which are not horizontal to give a slight overall inclination to the cover.

Figures 13a and 13b show an upright formed by an extruded aluminum alloy profile in a longitudinal direction, comprising in its cross section on the front side indicated by the arrow AV, a central groove 102 bordered on each side of a closed box 104.

The upright is symmetrical about an axis of symmetry A arranged in the front / rear direction.

The rear side has two parallel ribs 106 facing rearward, and at each end a hook 108 facing inward, giving rigidity to the upright as well as possibilities of attachment to a support such as the wall of a building for example .

The central groove 102 comprises on each side from the rear, a main recess 110 then an annex recess 112, these two recesses of rectangular section, separated by a partition 116 arranged in the transverse direction, being open towards the axis of symmetry A.

The bottom of the groove 102 comprises a succession of glued strips 114 regularly spaced, centered in the middle of this groove, comprising looped wires intended to receive the attachment of an additional strip having hooks forming a rapid fixing system of the type " Velcro ”. Any other compatible fixing device may be used.

FIGS. 14a and 14b show a bead 122 fixed continuously to a reinforcing strip 124, which is itself fixed behind the hooking side of a first fabric 120 so as to present a large adhesion surface between this strip and this canvas.

In this way a pull on the bead 122 fixed continuously and solidly on the first fabric 120, achieves a uniform tension of the fabric along its hooking side.

The first fabric 120 coming from the left side is approached on the front of the upright, the bead 122 coming in front of the central groove 102, the reinforcing strip 124 coming on a lateral front face of this upright.

FIGS. 15a and 15b show the bead 122 of the first fabric which is pushed towards the bottom of the groove 102, then in the main hollow 110 on the left side of this groove.

In parallel, a second fabric 130 coming from the right side is approached on the front of the upright, its bead 122 coming in front of the groove 102.

FIGS. 16a and 16b show a stop 140 formed by a section of profile produced by extrusion of an aluminum alloy, having its length formed in the direction of extrusion, which is arranged horizontally.

The flat rear face 142 of the cleat comprises a fastening strip equipped with hooks turned towards the rear, intended to be fixed on the glued strip 114 at the bottom of the groove 102. As a variant, any other type of rapid fixing of the cleat to the profile can be used, such as a clipping device.

The front face of the cleat 140 has two gripping edges 144 facing forward, each projecting upwards or downwards, facilitating the gripping of this cleat by putting a finger on each side to pinch it.

The insertion of each cleat 140 at each glued strip 114 is done by sliding the left side of this cleat towards the bottom of the groove 102, pressing on the first fabric 120, then by tilting its right side towards the bottom for pushing the bead 122 of the second fabric 130.

In this way the bead 122 of the second fabric 130 is also pushed first towards the bottom of the groove 102, then towards the main hollow 110 on the right side of this groove. During this operation the bead 122 of the first fabric 120 is held at the bottom of its main recess 110, by the left side of the cleat 140 resting on this fabric.

Advantageously, the cleats 140 fill a large part of the width of the groove 102, in particular more than 90%, to facilitate their insertion while preventing the exit of the beads 122.

Figures 17a and 17b show the end of the fitting of the cleat 140, its rear fastening strip coming to be fixed on the glued strip 114 to hold it firmly in position. Each side of the cleat 140 symmetrically blocks a bead 122 in its main hollow 110.

It will be noted that a traction of each fabric 120, 130 formed by the transverse tension of this fabric, applies a traction towards the front of its bead 122 which is supported on the partition wall 116 retaining this bead.

Each side of the stopper 140 receives a lateral thrust coming from the pull on the bead 122. The stopper 140 does not undergo forward pulling force, which means that its catching by a simple and economical device of the strip type " Velcro "is quite sufficient.

It will be noted that the rear face of the fabric 120, 130 resting on the upright, in particular at the level of the elbows formed on the front face of this upright and at the end of the partition 116, is reinforced by the reinforcing strip. 124 which ensures the longevity of the fabric, in particular with friction coming from movements caused by strong winds.

In this way, a simple, rapid and continuous fixing is carried out over the entire length, to one side of the fabric 120, 130, requiring no tool for its installation, which can be carried out without effort, in particular by an operator. mounted on an elevator.

Figure 18 shows the laying on the ground of longitudinal members 30 and main crosspiece 32 connected together, in order to form a grid over the entire floor of the tent.

FIG. 19 shows the installation of small sleepers 70 connecting the main sleepers 32, as well as of panels 54 covering the grid, fixed by their hooks to the side members 30.

Figure 20 shows the finished floor, comprising a set of panels 54 fitted together to form a smooth floor.

Figure 21 shows on a first longitudinal side the installation of lateral masts 4 each supported by a vertical upright 6, each mast being disposed at the junction of a beam 30 and a main cross member 32 in order to place its amount on a cross member to secure it firmly. Each assembly comprising a lateral mast 4 and an upright 6 is easy to handle by a single person.

FIG. 22 shows the installation of an upper spar 20 and an intermediate spar 22 connecting all of the masts 4.

Figure 23 shows the installation of the side masts 4 and the crosspieces 20, 22 on the second longitudinal side.

The tent according to the invention allows modular mounting, easily adjusting the length with a number of cross members 32 and 4 variable side masts. In this case, the length of the cover fabric 8 is adjusted.

FIG. 24 shows the installation of the covering fabric 8. For this, it is possible to fix a first longitudinal side on an upper spar 20, then the second side on the opposite upper spar, applying no tension or a low transverse tension which facilitates this pose.

Lastly, the two points of attachment to the ground 12 are placed at the ends, and a tension is applied to each of these points, for example with a lever and ratchet system allowing this tension to be applied easily and effortlessly.

One obtains at once with the two end tension systems, a longitudinal tension giving in this direction the upward curvature, as well as a transverse tension giving in this direction the downward curvature, ensuring in particular the flow of water.

Then hang the side fabrics if necessary and the end fabrics to completely close the tent, which can be opaque or transparent. We can also add internal partitions in the transverse direction, between the two lines to form compartments, by connecting with a stretched canvas two side masts 4 arranged opposite one another.
