TENT WITH ROLLER FRAME

Abstract

A tent that rolls up for storage and unrolls for setup and use, its structure is firm when open and compact when rolled up. When open, it resembles a four-sided pyramid, and when closed, it's roughly square. The structure is divided into several sections that, when rolled up, collapse into a small, easily transportable package in a backpack. When opened, the sections align to form a firm, complete structure. It also features drawstrings to tension the structure for added stability if needed, as it is already self-supporting when open. This tent offers firmness when open, quick setup, and a compact size for easy transport.

Description

TENT WITH ROLL-UP FRAME BACKGROUND The present invention relates to the field of tents. Tents consist of a frame or skeleton and a fabric or fabrics that form the walls and floor. The fabrics used for tent construction are the same or very similar in products currently on the market, but this is not the case with the frames or skeletons; these structures vary in shape and size. There are foldable tents, known in the market as "pop-up" tents, which, when folded for storage, would not fit in a backpack measuring 30 cm x 20 cm x 50 cm. Furthermore, when opened, the frame is not very sturdy.Another type of tent is the folding tent, made up of several poles that the user has to connect one by one to form the frame and then place it on the fabric. These frames are sturdy when assembled, but when folded for storage, they won't fit in a backpack, and they are also time-consuming to set up. These tents don't solve the need for a sturdy, easy-to-carry, and easy-to-assemble tent. DESCRIPTION This invention relates to a tent that can be rolled up to a compact size for easy transport and storage, fitting easily into a traveler's backpack. When unrolled, the tent is sturdy and easy for the user to assemble. The tent consists of a rigid frame and flexible walls and floor. When open, the tent is shaped like a four-sided pyramid. The rigid frame (1) comprises four blocks at the apex (3) and four poles (8), which form the vertices of the pyramid. These poles extend from the ground to meet at the pyramid's apex, and form the four bases (4, 5, 6, and 7). The flexible walls and floor (2) are made of fabric that adapts to the movement of the rigid frame. One wall includes an entrance door, and another wall contains a window. The apex of the pyramid (3), where the pole tips meet, is formed by 4 blocks. Viewed from above, the blocks form an X when the tent is opened (34). As an example of representation using the shape of an X, to join the 4 lines of the X they can be rotated to form a single line. Similarly, the blocks are rotated so that their walls meet and form a single block (14). Describing each block, block “A” (9) has a connection to a tube and a hole through which a cord passes. It has an extension made of a different material than the other blocks. This extension is the center where the other 3 blocks rest to give the tent its open position. It also has 2 circles with holes zn / cnn / eznz / e / Yi through which the pivot axis (similar to a hinge) passes, one circle on each side. These axes allow the surrounding blocks to rotate and position themselves when opening or closing the tent. Block “A” is connected by axles to block “B” and block “D”. Block “B” (10) has a pipe connection, a hole for a cord, and two circles, one on each side, for two axles: one axle connected to block “A” and the other to block “C”. Block “C” (11) has a pipe connection, a hole for a cord, an axle, and a circle on one side that houses an axle which connects to block “B”. Block “D” (12) has a pipe connection, a hole for a cord, and a circle that houses the axle which connects to block “A”. The circles of the blocks are joined by axle pins (13) that allow them to rotate for positioning. Below the blocks are the component arrays. An array consists of the following: male insert (15), tube (16), and female insert (17). A pivot pin (18) is used to join the arrays. These pivot pins allow an entire array, and also a group of arrays, to rotate. The configuration and order of the arrays are the same for all four posts. The tube size increases in increments of three arrays. Viewed from the top to the bottom, the first 3 arrangements have the same length (19), and arrangement number 4 (20) has a longer tube, long enough so that the previous arrangement does not exceed the length of tube 4 and does not reach the edge of tube 4. The number of arrangements and size of tubes will change depending on the size of the tent, as an example and for the case of a tent that fits 3 people lying down the following arrangement is used: 3 tubes of 5 cm, 3 tubes of 10 cm, 3 tubes of 15 cm and 3 tubes of 20 cm.The purpose of increasing the lengths of the tubes is so that when the entire structure is rolled up, the assemblies (an assembly consists of 3 arrangements) can fit the smallest one inside the next larger one and so on. Both the male and female inserts consist of a circle, and the hinge (21) is formed between the circle of the male insert and the circle of the female insert, plus an axle pin. This hinge allows the entire assembly to rotate. The inserts have a front wall that limits the rotation of the arrangements. When the tent is opened, the two walls make contact. The male insert has a hemisphere on its front wall, while the female insert has a recess shaped like the hemisphere of the male insert. This design allows the sphere to help center the arrangement against the other when it is rotated, as the hemisphere fits into the recess. The frames rotate to roll up and open the tent (21). When opening the tent, it was mentioned earlier that the walls of the inserts limit the movement of the frames. When the frames rotate, the walls of the inserts make contact, and by doing this, the walls of the frames remain firm. The hinge axes (or axes of the inserts) face inwards, which helps to keep the frames in place due to the weight of the structure itself, without needing to tension the poles to hold them in place. But to improve stability, a cord is added that passes through the inside of the entire pole (27), one cord per pole. The cord has a hook attached at its end, which hangs freely from the base of the pole, and at the other end it has a stop that prevents the cord from coming out of the pole. This stop is on the blocks at the top of the structure.As the cord passes from one end of the pole to the other through the guy lines, pulling the cord and securing it with a hook in a special loop (28) tensions all the guy lines, making the structure more stable. This tension is not required to set up the tent; it is only needed to improve the overall stability of the structure if necessary, since the tent can be left open for use without the cord being tensioned. The base of the pole is attached to the last arrangement, this base (26) makes contact with the ground where the tent will be placed, the base has a hole where a stake is inserted to bury in the ground and fix the tent to the ground, as well as the cord with hook, the stake is only used if greater firmness is required, by itself the tent without stakes remains open for use. The pole structure is attached to the soft (fabric) walls and floor with clamps. At least one clamp is used per arrangement, positioned as close as possible to the top and base of the poles. Because the walls and floor are attached to the structure, when the poles are rolled up or extended, the fabric moves with the structure. On one of the walls is the store's entrance door, which opens with a zipper, and on the wall opposite the door is a window that also opens with a zipper. BRIEF DESCRIPTION OF THE FIGURES Figure 1.

Claims

1. A tent that can be easily rolled up to a compact size for convenient transport and storage, fitting easily into a travel backpack. When unrolled, the tent is easy to set up and sturdy. This tent has a rigid part (1) and a soft part (2). When open, the tent is characterized by its four-sided pyramid shape. The rigid part is the frame that gives the tent its shape and forms the vertices of the pyramid, while the soft part consists of the walls and floor. The frame provides stability when the tent is unrolled or open. The soft part, made of fabric, consists of the walls and floor, attached to the frame. One wall includes the entrance door, and another has a window.

2. According to claim 1. The firm part (the structure) unrolls to open the tent, the soft part (walls and floor) of the tent, being attached to the structure, follow the unrolling motion.

3. According to claim 1. The firm part (the structure) is rolled up to close the tent, the soft part (walls and floor) of the tent, being attached to the structure, follow the rolling motion.

4. According to claim 1. The sturdy structure is composed from the top to the ground of: a set of 4 blocks (3), 4 posts (8) and the 4 bases (4, 5, 6 and 7). Through these elements, on the inside, passes a cord with a hook at its end (27), 4 cords in total.

5. According to claim 4. The apex of the pyramidal structure, where the posts meet, is made up of 4 blocks (3). The different blocks are composed as follows: block “A” (9) has its connection to a tube and a perforation through which a cord passes. This block is the largest of the others because it has a protruding piece of material that acts as a center on which the other 3 blocks rest to give the tent its open position. It also has 2 circles with perforations through which the pivot pin passes (this circle, with the axle, functions as a hinge), one circle on each side of the block. These circles, together with the axles, allow the adjacent blocks to rotate and position themselves for opening or closing the tent. Block “A” is joined by the axles to block “B” and to block “D”.Block “B” (10) has a tube connection, a cord hole, and two circles, one on each side, for two pivot pins. One shaft connects it to block “A,” and the other shaft connects it to block “C.” Block “C” (11) consists of a tube connection, a cord hole, and a circle that houses the pivot pin. It connects to block “B” via the pivot pin. Block “D” (12) consists of a tube connection, a cord hole, and a circle that houses the pivot pin. It connects to block “A” via the pivot pin. The blocks have circles through which the pivot pins pass, allowing them to rotate into open and closed positions. There are a total of three pivot pins (13) connecting the four blocks.

6. According to claim 4. Attached to the lower part of the blocks are the poles (8) that reach the base of the structure. These poles are made up of several component assemblies that roll up to close the structure or unroll to open it. The number of assemblies depends on the final size of the tent. An assembly consists of: a male insert (15) with a hemispherical material elevation that, when rotated to join, centers the position; a tube (16); and a female insert (17) that has a hemispherical counterpart to the male insert, which, when rotated, engages with the male insert. The entire assembly is hollow in the center, through which the cord passes. Between two assemblies is a pivot pin (18). This pin serves to join two assemblies and also acts as the axis of rotation for the assemblies. In this way, a single assembly and also sets of assemblies can be articulated; a set of assemblies consists of three joined assemblies (19).The length of the tubes remains the same in a set of arrangements, increasing in the next set. That is, starting from the top of the pyramid, the first three arrangements have the same length, and the fourth arrangement (20) increases in length. The increase in length is such that, when comparing arrangement 3, it should not be greater than two-thirds the length of arrangement 4.

7. According to claim 2. When rotating an arrangement for opening the tent (unrolling), the walls of the male and female inserts come together, limiting the rotation, in addition to aligning the arrangements forming a tube with the length of 2 arrangements, so on when rotating all the arrangements and aligning, a tube is formed with the length of one vertex of the pyramid, the rotations and alignment of the arrangements works in the same way for the 4 posts.

8. According to claim 3. When rotating an arrangement (21) for closing the tent (rolling it up), it rotates in the opposite direction to the opening rotation. This causes the large tube, the size of the tent's apex, to fragment into smaller components, the size of each arrangement. When rolling from the top, the first arrangement rotates until it makes contact with arrangement 2 and arrangement 3 (22), forming the first set (3 arrangements) an irregular shape. As rolling continues, the irregular shape makes contact with the fourth arrangement (23). Since the subsequent arrangements are longer, the shape of the first set is inside the shape of set 2, and this is repeated successively. Set 2 forms another irregular shape and is inside the irregular shape of set 3, and the shape of set 3 is inside the shape of set 4.The total size of the rolled-up tent is that of the irregular shape formed by the last set of arrangements, a shape similar to a square (24). zn / cnn / cznz / e / Yi.

9. According to claims 2 and 5. The blocks at the top of the pyramid, when the tent is closed, the blocks are aligned forming a line of blocks (14, 23), to open the tent, the blocks rotate positioning themselves in a cross shape (34).

10. In accordance with claims 2 and 6. With the tent open for use, all the axle pins that join the arrangements are positioned inwards (35). This means that when there are external loads from outside the tent inwards, the tent does not open further and its shape is not deformed, or it is not easily knocked down. The arrangements do not rotate further if pressure is applied or there are loads from outside inwards. When the pole is placed on the ground surface, the weight of the arrangements and the firm structure itself rotates and positions the arrangements without the need to tension or fix the tent to the ground.

11. According to claims 3 and 5. The blocks at the top of the pyramid, when the tent is open, the blocks are in the shape of a cross (34), to close the tent, the blocks are rotated positioning it in a single block in line (14, 29), when rotating the blocks the posts follow the movement of the blocks.

12. According to claim 4. At the bottom of the tent, where it makes contact with the ground, there is a rectangular base (26) connected to the tube of the last arrangement, with a hole for passing the cord, and another perforation in the rectangular part, the perforation serves to pass pegs through it, the pegs can be driven into the ground. There is one rectangular base for each pole.

13. According to claim 4. A cord with a hook (27) passes through the blocks, poles, and bases. This hook protrudes from the base, and the cord is attached to the top of the block. When the cord is pulled by the hook, it pulls tension on all the components from the top, increasing the overall stability of the pole. To keep the cord taut, it is hooked onto a loop positioned on one of the components (28). Using the cord and hooking it is only necessary for added stability; it is not required to keep the tent upright and in use.

14. According to claim 2. To open the tent, proceed as follows: unroll the structure either on the ground to extend the poles (32), then lift it by the blocks, or, without placing the tent on the ground, lift the structure by the blocks, letting the remaining arrangements fall by gravity, thus extending the poles, rotate the blocks until the cross (31) is formed, then place two rectangular bases on the ground and open the other two poles, place these same poles, which are gradually extended, on the ground, then take the other two poles and open them further, repeat opening the poles and placing them on the ground until they are fully extended. Once the poles are open, the pyramid is formed, and the tent is ready for use (30).This method is for one person only. With two people, each person takes two poles (or fewer if there are more people) and pulls them out simultaneously (zn / cnn / eznz / e / Yi) until the structure is fully open, and the tent is ready to use. If necessary, or if more stability is required, hook the cord into the hook fasteners. Stakes can be placed at the four bases for better tent stability. Without hooking the cords or using the stakes, the tent will stand on its own and can be used.

15. According to claim 3. To close the tent, proceed as follows: Lift the structure from the center, where the 4 blocks are located, raising it high enough so that the poles are lifted off the ground (31). Then, rotate the blocks to separate the cross of blocks, aligning them (32). It can then be rolled up in the air. Alternatively, after rotating the blocks, the structure can be placed on the ground and rolled up from the top or the blocks until the entire structure is rolled up. The tent is then ready for storage or transport (33).
