Description

  The present invention relates to a folding tent, and more particularly, to a folding tent that can be easily folded and unfolded.

  As an example of a conventional folding tent, when expanding the tent, hold the center tube with one hand, pull the rope with the other hand, move the cap upward, and expand it by pulling it up into the hub When the folding tent is folded, an operation is performed to remove the cap in the hub, and the cap is folded by pushing down until the cap is almost reversed (see Patent Document 1). .

  As an example of a tent with an umbrella-like structure, the upper runner has a plurality of upper main bones and a secondary bone extending from the umbrella. The lower runner is below the upper runner. Multiple stretchers are stretched. The end of each stretcher is connected to the upper main bone and the secondary bone of the umbrella. A joint is installed in the center of the lower runner, and the joint has a joint spring. A rope extends from the joint. In this case, when unfolding the tent, hold the upper runner part with one hand and pull the rope up with the other hand. The joint goes out through the inside of the upper runner. It is known that when the upper runner hits the upper runner fixing block, the spring portion of the spring body stops at the outer edge of the upper runner and is fixed (see Patent Document 2).

  In the tent of Patent Document 1, when unfolding the tent, while holding the central tube with one hand, pulling the rope with the other hand and pulling the cap into the hub, The cap is pushed down, pulled out of the hub and folded.

  In the tent of Patent Document 2, when unfolding the tent, hold the upper runner part with one hand, pull the rope upward with the other hand, and pass the lower runner through the upper runner. In the case of folding, the lower runner is pushed down, the lower runner is pulled downward from the upper runner, and folded.

  However, in configurations such as Patent Document 1 and Patent Document 2, a considerable force is required to pull the rope with one hand. In addition, in order to pull upwards, it is necessary for the operator to raise his arms to the upper side, and workability is poor. Also, when folding, the operator pushes down the cap (lower runner) with the arm extended to the maximum, so the worker cannot exert enough force in this position, and there is a strong demand for improvement. Yes.

  The present invention has been made to solve the above-described conventional problems, and a main object of the present invention is to provide a folding tent that can be easily unfolded and folded.

  In order to achieve the above object, according to the present invention, a tent can be expanded and folded by one touch by opening and closing a skeleton arm member.

  Specifically, the first device is provided with a top member in the center, one end is connected to the periphery of the top member so as to be pivotable in the vertical direction, and the other end is a plurality of arms protruding radially from the top member. A folding tent provided with an inner tent on the inner side of the arm member, and each arm member has a first arm member having one end rotatably connected to the periphery of the top member in the vertical direction; A second arm member having one end connected to the other end of the first arm member so as to be rotatable in the vertical direction and the other end arranged on the ground, the guide being connected to the lower side of the top member and hanging down A cylindrical member is provided by being slidable in the vertical direction along the outer peripheral wall of the guide member, and one end is rotatably connected to the cylindrical member in the vertical direction and the other end Is up and down in the middle of each first arm member A stopper is provided at the lower end of the guide member for stopping the lowering of the tubular member. When the folding tent is deployed, the tubular member is slid downward. When the folding tent is folded, the lower end position moves to the lower end position, and the lower end position is configured such that the angle formed by the guide member and the connecting member is less than 90 °. The cylindrical member slides upward to the upper end position, and at the upper end position, the first arm member, the connecting member, and the guide member are parallel to each other, and the angle formed by the guide member and the connecting member is Sliding between the lower end position and an intermediate position that is configured to exceed 90 ° and is in the middle of the lower end position and the upper end position and an angle formed by the guide member and the connecting member exceeds 90 ° Working the cylindrical member and / or the connecting member By operates with, cylindrical member is characterized by being adapted to be slidable.

  According to a second device, in the first device, the guide member is formed of a hollow cylindrical member, and a spring member forcing the cylindrical member downward is housed in the cylindrical member, and the cylindrical member is The spring member assists the downward sliding when descending from the upper end position.

  According to a third aspect, in the second aspect, the spring member is housed and disposed in the cylindrical member so as to be movable in the vertical direction, and the cylindrical member is at the upper end position and the intermediate position. In this case, the spring member is compressed, and when the cylindrical member is located at the lower end position from the intermediate position, the spring member has a free length.

  A fourth device is the second device according to the second device, wherein the spring member is compressed and accommodated inside the cylindrical member, and is forced to slide the cylindrical member downward from the upper end position. In addition, the cylindrical member is prevented from sliding upward from the lower end position.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the top member is provided in a bowl shape in which the center protrudes upward and an internal space is formed, and the cylindrical member is located at the upper end position. The sixth device is characterized in that a part of the upper end portion of the cylindrical member is accommodated in the internal space when the first member is slid to the first device. In any one of the above, the second arm member includes a first intermediate leg and a first lower end leg, and the first arm member and the first intermediate leg are connected to each other and are folded outward. The first intermediate leg and the first lower end leg can be folded outward at the connection portion with each other so that the inward folding is restricted. It is connected so that folding may be controlled.

  According to a seventh aspect, in any one of the first to fifth aspects, the second arm member includes a second intermediate leg and a second lower end leg, and the first arm member and the second intermediate leg are The second intermediate leg and the second lower leg are connected to each other so that the outer part can be folded outward and the inward folding is restricted. The second intermediate leg is slidably housed inside.

  According to the first device, since the angle between the guide member and the connecting member is less than 90 ° when the operator operates from the intermediate position to the lower end position, the tubular member is inadvertently moved upward from the lower end position. Can be prevented from sliding. At the same time, when a force acts in the direction of folding the inner tent with the folding tent deployed, a force acts on the connecting portion between the connecting member and the guide member in the central direction and the lower side of the inner tent. The cylindrical member is fixed at the position, and can be stably maintained in a state where the cylindrical member is stopped at the lower end position, and the arm member can be maintained in the deployed state.

  According to the second device, when the cylindrical member descends from the upper end position, the spring member assists the downward sliding, so that it can be deployed from the folded state with a light force.

  According to the third aspect, the spring member is housed and disposed in the cylindrical member so as to be movable in the vertical direction. When the cylindrical member is at the upper end position and the intermediate position, the spring member is disposed. Is compressed, and when the cylindrical member is at the lower end position from the intermediate position, the spring member has a free length, so that when the cylindrical member is slid upward by operating from the lower end position, Since the spring member is lifted with a light force without causing resistance, the workability is excellent.

  According to the fourth device, since the spring member is forced to slide the cylindrical member downward from the upper end position, the connecting member is lowered when the arm member is expanded to expand the tent. And can be deployed easily. Further, since the cylindrical member is prevented from sliding upward from the lower end position, it is possible to prevent the cylindrical member from being unexpectedly detached from the lower end position and rising.

  According to the fifth aspect, since a part of the upper end portion of the tubular member is accommodated in the internal space, the connecting member can be lengthened, and a large living space in the inner tent is ensured. it can.

  According to the sixth device, the first arm member and the first intermediate leg, and the first intermediate leg and the first lower end leg only have to be spread on a plane. The arm member, the first intermediate leg, and the first lower end leg can be naturally deployed in a dome shape. Also, by folding the first lower leg and folding it together with the first intermediate leg, it can be folded almost parallel to the first arm member, so it can be easily folded and stored compactly, so it is convenient to carry. .

  According to the seventh aspect, when the first arm member is lifted in a state where the second arm member is tilted, the skeleton can be roughly deployed, and thereafter, the second intermediate leg is extracted upward from the second lower end leg. Because it can be done by locking, it has excellent operability, is tall, and can easily deploy large tents. Conversely, when folding, the height of the top member can be lowered by placing the second intermediate leg in the second lower end leg, and thereafter the first arm member is brought closer to the guide member. Since it suffices to fold and fold the second arm member, it is excellent in workability.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention, its application, or its use.

(Embodiment 1)
Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings. 1 to 14 show a first embodiment of a folding tent of the present invention, FIG. 1 is a perspective view showing an overall outline of the first embodiment, and FIG. 2 is a perspective view showing a state in which a fly sheet is removed in FIG. FIG.

  1 and 2, a folding tent 1 includes a cloth-made inner tent 2 that becomes a dome shape when unfolded, a skeleton 3 that suspends the inner tent 2, and a waterproof cloth rectangular shape that covers the skeleton 3. The fly sheet 4 is provided. After the inner tent 2 is deployed, the four corners are fixed to the ground with the pegs 5. Then, the fly sheet 4 through which the metal shaft 6 is passed in the center is placed on the framework 3, and the four corners of the fly sheet 4 are fixed to the ground with pegs (not shown). Note that the four corners of the flysheet 4 may be fixed to the pegs 5 at the four corners of the inner tent 2.

  In the present invention, the sky side when the tent is installed is referred to as the upper side, the ground side as the lower side, the inner side of the inner tent as the inner side, and the outer side of the tent as the outer side. In the following description, unless otherwise specified, the description will be made in accordance with the above description.

  Next, the detailed structure of the framework 3 will be described.

  As shown in FIG. 2, the framework 3 includes a top member 10 made of a synthetic resin with the shape of the collar turned upside down at the center, and an arm member 20 formed of four metal pipes that protrude radially from the periphery of the top member 10. A synthetic resin guide member 30 that is integrally connected to the lower surface of the top member 10 and hangs down, and a connecting member 40 that is a metal pipe that connects the arm member 20 and the guide member 30 to each other.

  As shown in FIG. 2, each arm member 20 includes a first arm member 21 and a second arm member 22. One end 21 a of the first arm member 21 is pivotally supported by a pin (not shown) so as to be rotatable in the vertical direction around the top member 10, and the other end 21 b is rotated in the vertical direction on one end 22 a of the second arm member 22. It is pivotally supported by a pin. The other end 22b of the second arm member 22 is disposed on the ground. The second arm member 22 includes a first intermediate leg 23 and a first lower end leg 24. Specifically, one end 23 a of the first intermediate leg 23 is pivotally supported by a pin so as to be pivotable in the vertical direction on the other end 21 b of the first arm member 21, and the other end 23 b is one end 24 a of the first lower end leg 24. Is pivotally supported by a pin so as to be pivotable in the vertical direction. The other end 24 b of the first lower end leg 24 is attached to the ground with the peg 5.

  As will be described in detail later, the central top of the inner tent 2 is connected to the lower end of the guide member 30 with a string 7 and is suspended. Further, the first arm member 21 is formed on the cloth hollow cylinder 8a sewn on the outer surface of the inner tent 2, the first intermediate leg 23 of the second arm member 22 is formed on the cloth hollow cylinder 8b, and the second hollow cloth 8c is formed on the cloth hollow cylinder 8c. The first lower end legs 24 of the arm members 22 are passed through the inner tent 2 so that the inner tent 2 can be deployed and stretched together with the framework 3 when the framework 3 is expanded or folded. In this way, the inner tent 2 can be suspended inside the framework 3 during deployment.

  One end 40 a of the connecting member 40 is pivotally supported by the cylindrical member 32 so as to be vertically rotatable, and the other end 40 b is pivotally supported by an intermediate portion of the first arm member 21 so as to be vertically rotatable.

  A state where the framework 3 of the folding tent 1 is unfolded and a state where it is folded will be described with reference to FIG.

  As shown on the right side of FIG. 3, when the framework 3 of the folding tent 1 is unfolded, the cylindrical member 32 slides downward to become the lower end position B where it abuts against the stopper portion 36. The angle α formed by the member 30 and the connecting member 40 is less than 90 °. Actually, the angle is slightly smaller than 90 °. That is, the other end 40 b of the connecting member 40 is slightly higher than the one end 40 a of the connecting member 40. From this state, if the connecting member 40 slides upward and the one end 40a of the connecting member 40 is relatively higher than the other end 40b of the connecting member 40, the guide member 30 and the connecting member It is necessary that the angle α formed by 40 is less than 90 ° and straddles the 90 ° angle position and exceeds 90 °. Usually, the first arm member 21 and the second arm member Even when a force is applied in the direction in which the cylinder 22 is folded, the cylindrical member 32 is set at an angle at which it is difficult to slide upward from the lower end position B (position where it abuts against the stopper portion 36). Therefore, in the middle of the lower end position B and the upper end position A, the sliding between the intermediate position C and the lower end position B where the angle α formed by the guide member and the connecting member 40 exceeds 90 ° is the cylindrical member 32. In addition, the tubular member 32 can be slid by the operator holding and operating the connecting member 40.

  The top member 10 has a shape in which the center protrudes upward, and the shape of the ridge formed with the internal space is turned upside down. The guide member 30 is fixed to the inner center of the ridge shape, and the cylindrical member 32 has an upper end. When the position is reached, a part of the upper end of the cylindrical member 32 can enter the internal space. By setting it as this structure, the connection member 40 can be lengthened. That is, the length of the connecting member 40 may be substantially the same as the length from the one end 21a of the first arm member 21 to the connecting position where the first arm member 21 is connected to the connecting member 40. As a result, a wide living space in the inner tent 2 when the inner tent 2 is deployed can be secured. Further, as described above, if the length to the connection position and the length of the connecting member 40 are substantially the same, the length that the cylindrical member 32 is difficult to slide upward from when the cylindrical member 32 is at the lower end position. This is convenient.

  As shown on the left side of FIG. 3, when the folding tent 1 is folded, the cylindrical member 32 slides upward to reach the upper end position A. At the upper end position A, the guide member 30 and the connecting member 40 are formed. The angle is configured to exceed 90 °. Actually, the first intermediate leg 23 and the first lower leg 24 of the first arm member 21 and the second arm member 22 and the first intermediate leg 23 are folded and are substantially parallel to each other. At the upper end position A, the guide member 30 and the connecting member 40 are at an angle nearly parallel.

  The connection between the other end 21b of the first arm member 21 and one end of the first intermediate leg 23 and the connection between the other end of the first intermediate leg 23 and one end of the first lower end leg 24 will be described with reference to FIG. . The other end 21b of the first arm member 21 has a semicircular receiving portion 25a. A pin 26a is attached to the receiving portion 25a, and one end of the first intermediate leg 23 is inserted into the receiving portion 25a. A pin is inserted into a through hole 27 a provided at one end of the intermediate leg 23. With this configuration, the first intermediate leg 23 can be rotated upward and downward with respect to the first arm member 21 and cannot be rotated inward. Further, the connection between the first intermediate leg 23 and the first lower end leg 24 has the same configuration as the above connection, except that the through hole of the first lower end leg 24 is a long hole 27b. It is. By using this long hole 27b, when the pin 26a is at the lower end of the long hole 27b (when the first lower end leg 24 is inserted into the receiving portion of the first intermediate leg 23), the first lower end leg 24 is It cannot rotate outwards and can maintain its deployed state stably. On the other hand, in the case of folding, the first lower end leg 24 is pulled away from the first intermediate leg 23 in the state shown in FIG. 5 so that the pin 26a is positioned at the upper end of the long hole 27b. As a result, the first lower end leg 24 and the first intermediate leg 23 can rotate relatively outward.

  With reference to FIGS. 8-13, the detailed structure of the top member 10 guide member 30 and the cylindrical member 32 is demonstrated.

  The guide member 30 is made of a synthetic resin hollow cylindrical member, and the upper end of the guide member 30 is fixed to the center on the inner surface side of the top member 10 having a shape in which the heel is turned upside down with a bolt or the like. A cylindrical member 32 made of synthetic resin is extrapolated on the outer peripheral wall 31 of the guide member 30 so as to be slidable in the vertical direction. The guide member 30 is provided with two long holes 33 facing each other in the vertical direction. The connection shaft 34 is provided so as to extend in a direction perpendicular to the axis of the guide member 30, pass through the two long holes 33, and fit into the inner surface of the cylindrical member 32.

  The cylindrical member 32 has an upper end position A near the upper end of the guide member 30 as shown in FIGS. 9 and 12, and a lower end position B near the lower end of the guide member 30 as shown in FIGS. Between the guide member 30 and the outer peripheral wall 31 of the guide member 30. Further, as shown in FIGS. 10 and 13, it also stops at an intermediate position C between the upper end position A and the lower end position B. The upper end position A, the lower end position B, and the intermediate position C will be described in detail in the description of the developed state later.

  When the cylindrical member 32 moves up and down along the outer peripheral wall 31 of the guide member 30, the connection shaft 34 is formed in the guide member 30 and in the two elongated holes 33 as a spring member that forces the cylindrical member 32 downward. It is designed to move up and down. A compression spring 35 is disposed inside the guide member 30 and above the connection shaft 34. The compression spring 35 is not fixed anywhere and can move in the vertical direction between the lower surface of the top member 10 and the connection shaft 34. The length of the compression spring 35 is about half as long as the distance between the upper end position A and the lower end position B of the cylindrical member 32. When the cylindrical member 32 is at the upper end position A, as shown in FIG. 11, the distance between the lower surface of the top member 10 and the connection shaft 34 is shorter than the free length of the compression spring 35, and the compression spring 35 is compressed. Thus, the cylindrical member 32 is resiliently strong in the downward direction. When the cylindrical member 32 is at the lower end position B, as shown in FIG. 13, the distance between the lower surface of the top member 10 and the connection shaft 34 is longer than the length of the compression spring 35, and the compression spring 35 is free. Just by being on the connecting shaft at a length away from the lower surface of the top member 10, the spring force is no longer acting. Since the first arm member 21 and the second arm member 22 are deployed in a dome shape, even when a strong wind blows in a state where the inner tent 2 is deployed, the connection portion between the first arm member 21 and the second arm member 22 There is almost no possibility of being folded so as to be inside the inner tent 2, and there is no possibility that the cylindrical member 32 will rise unexpectedly. Therefore, it is not necessary to press the cylindrical member 32 positioned at the lower end position B with the compression spring 35, and the compression spring 35 is free.

  Further, the distance between the lower surface of the top member 10 and the connection shaft 34 is substantially the same as the length of the compression spring 35, and the compression spring 35 has a free length and contacts the lower surface of the top member 10 and the upper surface of the connection shaft 34. FIG. 12 shows this state. From this position to the position before the angle α formed by the guide member 30 and the connecting member 40 is 90 ° is an intermediate position C of the cylindrical member 32, and the cylindrical member is within the range of the intermediate position C. 32 stops. The intermediate position C will be described in detail later.

  A stopper portion 36 that receives the tubular member 32 is provided at a lower end portion of the guide member 30 at a portion where the tubular member 32 becomes the lower end position B. The stopper portion 36 is made of a synthetic resin shaft, and the top portion of the inner tent 2 is attached to the stopper portion 36 with a string 7. The stopper portion 36 also serves as a shaft that connects the stopper portion 36 and the upper portion of the inner tent 2 with a string 7.

  Next, a procedure for unfolding the folding tent 1 will be described with reference to FIGS.

  First, as shown in FIG. 4, the folding tent 1 is taken out from the bag (not shown), and the framework 3 is set up with the top member 10 facing up. When the second arm member 22 is released with the skeleton 3 in the upright state, the second arm member 22 falls and lies on the ground. At this time, as shown in FIG. 5, the first lower end leg 24 overlaps the first intermediate leg 23 of the second arm member 22 and lies. From the state where the first lower end legs 24 of the four second arm members 22 lie down, the first lower end leg 24 of the second arm member 22 is unfolded and the other end side of the first lower end leg 24 is expanded as shown in FIG. The first lower end leg 24 is positioned on the extended line of the first intermediate leg 23 and is expanded so that they are substantially in the same plane. In this state, as shown in FIG. 9 and FIG. 12, the cylindrical member 32 is at the upper end position A, and a part of the one end 32 a of the cylindrical member 32 is contained in the bowl-shaped inside of the top member 10.

  From the states of FIGS. 6, 9, and 12, the operator holds and lifts at least one of the first arm member 21 and the connecting member 40. The state in the middle of lifting is shown in FIG. 7, FIG. 10 and FIG. When the top member 10 is lifted, the first arm member 21, the connecting member 40, and the cylindrical member 32 are also lifted together with the top member 10 being lifted. When the first arm member 21 and the connecting member 40 are lifted, the other end 21b of the first arm member 21 rises while spreading outward, so that the other end 21b of the first arm member 21 and the second arm member 22 Although both ends 22a are spread outward, the distance between the other ends 24b of the adjacent lower end legs 24 is substantially equal to the length of the lower end of the inner tent 2, so that the top member 10 and the first lower end legs 24 The first arm member 21, the first intermediate leg 23, and the first lower end leg 24 expand in a continuous dome shape. As a result, as shown in FIG. 8, the second arm member 22 rotates inward with respect to the first arm member 21, and the first arm member 21, the first intermediate leg 23, and the first lower end leg 24 move. The inner tent 2 can be expanded together with a dome shape. For the sake of explanation, the state of FIG. 7 has been described. However, when the state is developed, the state of FIG. 8 is immediately changed from the state of FIG.

  When the operator holds and lifts at least one of the first arm member 21 and the connecting member 40, the other end 21b of the first arm member 21 expands outward, and the cylindrical member 32 is guided by the guide member 30. Along the outer peripheral wall 31 of the The downward movement is supported by the compression spring 35. That is, since the compression spring 35 is compressed at the upper end position A, when the operator lifts the first arm member 21 and the connecting member 40, the other end 21b of the first arm member 21 expands in a direction away from it. The other end 40b of the connecting member 40 is in a direction away from the guide member 30, and the cylindrical member 32 is moved in a direction descending from the upper end position A. The compression spring assists so that the cylindrical member 32 moves in the direction of descending from the upper end position A. The lifting operation is assisted by the compression spring 35 and can be operated with a light force.

  Specifically, in the state of FIG. 6, the cylindrical member 32 is in the upper end position and the compression spring 35 is compressed, and the spring force is acting in the direction in which the cylindrical member 32 is lowered. As shown in FIG. 7, when the cylindrical member 32 is lowered, it is assisted in the direction in which the first arm member 21 expands.

  Next, in the state of FIG. 8, the framework is operated from the state of FIGS. 10 and 13 to the state of FIGS. That is, the tubular member 32 is pushed down to the lower end position B by holding the connecting member 40 in the hand. At this time, the cylindrical member 32 comes into contact with the stopper portion 36 to reach the lower end position B, and the angle between the connecting member 40 and the cylindrical member 32 is less than 90 ° from the angle exceeding 90 °. The connecting member 40 is positioned such that one end 40a is lower than the other end 40b. At the lower end position B, when a force is applied in the direction in which the first arm member 21 is folded, the force is applied to the connecting member 40 in the inner side direction and the lower side direction. Can be prevented from sliding upward. Therefore, in the first embodiment, the cylinder member 32 is simply lowered to the lower end position B without adding a lock mechanism having a stopper function and stopping the rise of the cylinder member 32. Since it is good, an operator's operation is easy and it can hold | maintain in the lower end position B reliably.

  Next, the case of folding will be described. When the folding tent 1 is folded, the connection member 40 is held in the hand, the one end 40a side of the connection member 40 is lifted upward, and the cylindrical member 32 is slid upward. As a result, the cylindrical member 32 moves from the lower end position B to the intermediate position C. At this time, since the cylindrical member 32 is lifted from the lower end position B and can be slid upward from the lower end position B in contact with the stopper portion 36, the folding operation is easy and excellent in workability.

  Next, the first arm member 21 is moved in a folding direction, that is, a direction parallel to the guide member 30, and the other end 21 b of the first arm member 21 is brought close to the lower end of the guide member 30. At this time, the compression spring 35 is compressed, the cylindrical member 32 slides upward, rises to the vicinity of the upper end position A, and the state shown in FIG. 5 is obtained. When the first arm member 21 is brought as close as possible to the cylindrical member 32, the cylindrical member 32 is at the upper end position A. However, in the state of FIG. The other end 21b of the arm member 21 is in a slightly expanded position. Therefore, in the state of FIG. 5, the cylindrical member 32 is set to a position close to the upper end position A. As long as there are a plurality of workers and they can be held so as not to fall down, they may be folded up to the upper end position A in the state of FIG.

  Thereafter, the first lower end leg 24 is pulled away from the first intermediate leg 23 so that the first lower end leg 24 can be rotated outward in the vertical direction. Then, returning to the state of FIG. 4, the first lower end leg 24 on the left side in the drawing is rotated in the clockwise direction, and the first lower end leg 24 on the right side is rotated in the counterclockwise direction, thereby the first intermediate leg 23. Overlay on top. And the 1st intermediate leg 23 and the 1st lower end leg 24 are lifted together, and the connection part of the 1st intermediate leg 23 and the 1st lower end leg 24 is made to approach the upper part of the guide member 30. FIG. That is, the first intermediate leg 23, the first lower end leg 24, and the guide member 30 are substantially parallel. Thereafter, the inner tent 2 is compressed and folded so as to surround the framework 3 while the air in the inner tent 2 is evacuated.

  In the first embodiment, the operator operates from the intermediate position C to the lower end position B so that the angle formed by the guide member 30 and the connecting member 40 is less than 90 °, so that the cylindrical member 32 is inadvertently moved to the lower end position. Can be prevented from sliding upward. At the same time, when a force acts in the direction of folding the inner tent 2 with the folding tent 1 unfolded, a force is exerted on the connecting portion of the connecting member 40 and the guide member 30 in the central direction and the lower side of the inner tent 2. Therefore, the cylindrical member 32 is fixed to the lower end position B, and can be stably maintained in a state where the cylindrical member 32 is stopped at the lower end position B. The first arm member 21 and the second arm The member 22 can be maintained in the developed state.

(Embodiment 2)
The second embodiment will be described with reference to FIGS. In the second embodiment, only parts different from the first embodiment will be described, and description of common parts will be omitted.

  The second embodiment is different from the first embodiment in the structure of the framework 3X, and the inner tent 2X is also different in accordance with the structure. Specifically, the second arm member 22X is raised with respect to the first arm member 21X in a bent angular relationship, and the second lower end leg 24X of the second arm member 22X is connected to the second intermediate leg 23X. The second intermediate leg 23X is housed in the second lower end leg 24X. A structure in which the second intermediate leg 23X enters the second lower end leg 24X is common, and details thereof are omitted. However, as shown in FIG. 16, the lock portion 29 is turned on and off to be locked. And switch to unlocked state. In the locked state, the second intermediate leg 23X is locked with respect to the second lower end leg 24X so that it cannot be inserted and removed, and in the unlocked state, it can be inserted and removed.

  Further, the compression spring 35X in the guide member 30 has such a length that it is compressed even when the cylindrical member 32 is at the lower end position B. Thus, when the cylindrical member 32 is at the lower end position B, the cylindrical member 32 is prevented from being unexpectedly raised and disengaged from the lower end position B. In the second embodiment, the second arm member 22X is connected to the first arm member 21X at an angle bent at a predetermined angle. Therefore, when a strong wind blows compared with Embodiment 1, it may bend so that the connection part of the 1st arm member 21X and the 2nd arm member 22X may become inside the inner tent 2X. Since the tubular member 32 may rise unexpectedly when the bending movement occurs, even when the tubular member 32 is at the lower end position B, the tubular member 32 is raised by being pressed by the compression spring 35X. Is to prevent.
