Description

  The present invention relates to a folding tent that is set up at the time of outdoor events, for example.

  Conventionally, tents having a structure in which a tent is supported by a plurality of support columns and a frame connected to the support columns have been widely used.

  Various structures exist for the structure of the support column and the frame. Among these, as a folding tent that facilitates folding by supporting the support column and the frame so as to be slidable and rotatable, For example, there are those described in Japanese Patent No. 2949648 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2001-288933 (Patent Document 2).

  These tents 101 are as shown in FIG. 19 and FIG. 20 in a state where the columns and the frame are spread, and the columns 102 are connected to the columns 102 extending upward from the installation surface such as the ground. A bellows-like outer peripheral frame 103 is provided. The outer peripheral frames 103 are connected to each other by a reinforcing frame 104. A center column 105 is provided at the intersection of the reinforcing frames 104 and at the center of a polygon formed by the outer peripheral frame 103. The awning 106 serving as the roof portion of the tent is supported by the outer peripheral frame 103 and the central column 105 as shown in FIG.

However, when the central column 105 is supported by the reinforcing frame 104 in this way, the center column 105 is set at the same time when the tent 101 is installed. Since the support column 105 moves up, there is a problem that the work of expanding the frames 103 and 104 becomes heavy. In particular, this problem becomes more conspicuous when the length of the central column 105 is increased in order to bring the top of the roof to a high position. Further, in this structure, the position of the apex of the central support column 105 is fixed when the reinforcement frame 104 has been expanded, so that the reinforcement frame 104 may be attached only to the apex portion of the awning 106 in some cases, such as on a windy day.

  Hereinafter, a first example of the embodiment of the present invention will be described with reference to the drawings. 1 and 2 are explanatory views showing the structure of the tent of this embodiment, and FIG. 3 is an explanatory view showing the structure of the reinforcing frame.

  The folding tent according to the present invention is configured as a temporary tent so that it can be easily set up and withdrawn outdoors. Specifically, as shown in FIG. 2, the support column 2, the outer peripheral frame 3 and the reinforcement frame 4 as frames connected to the support column 2, the center support column 5 and the like are combined so that folding is possible. Yes, by covering and supporting the tent 6 made of a soft resin or the like on the upper part of the tent frame composed of these as shown in FIG. 19, it is possible to avoid sunlight and rainwater.

  The support column 2 is a rod-shaped member having one end arranged on an installation surface such as the ground and the other end arranged upward. In the present embodiment, four support columns 2 are used for each tent 1, and the support columns 2 are positioned at the apexes of a substantially square in plan view and are set up perpendicular to the installation surface. As a material of the column 2, a hollow square pipe that is linear in this embodiment is used.

  In addition, this support | pillar 2 is not restricted to the form of a present Example demonstrated above, It can implement by changing in various ways. For example, a curved rod-shaped body may be used, or the member may be arranged in an oblique direction with respect to the installation surface.

  Moreover, what joined the some rod-shaped body may be used. For example, it can be folded by storing a small-diameter rod-like body inside a large-diameter hollow rod-like body and pulling out the small-diameter rod-like body, or by providing a hinge at the joint between the rod-like bodies It is good also as what can be added by making it stick or sticking rod-shaped bodies together. In these cases, the rod-shaped body is provided with fixing means capable of adjusting the length. For example, a pin that can be inserted / removed is inserted into a hole formed on the side surface of each rod-shaped body, or is arranged on the other rod-shaped body with respect to a hole formed on the side surface of at least one rod-shaped body. For example, by fitting a projection biased by a spring. That is, as long as the outer peripheral frame 3 and the reinforcing frame 4 which will be described later are attached and the operation of the sliding member 2a that can slide along the support column 2 is not hindered, various forms of implementation are possible. Incidentally, although not shown, the support column 2 of the present embodiment is composed of two rod-shaped bodies, and a plurality of steps are formed by forming a plurality of holes and fixing each rod-shaped body with the holes. It is a telescopic type that can be adjusted in length.

  The number of support columns 2 per tent 1 is four in this embodiment, but is not limited to this. There are a plurality of three or more columns, and at least each support column 2 is the apex, and in plan view. Any number can be used as long as they form a polygon. Thus, for example, a rectangular shape in plan view (described later as a second embodiment), a pentagonal shape, and a six-pillar shape are also included in the technical scope of the present invention. Furthermore, the support pillars 2 may be arranged inside the polygon, and the support pillars 2 arranged in this way may also serve as the center support pillar 5 described later.

  The outer peripheral frame 3 connects the upper portions of adjacent struts 2 and has a bellows-like appearance and can be expanded and contracted. This outer peripheral frame 3 is a combination of outer peripheral unit pipe bodies 31a, 31b, 32a, 32b, which are linear rods in this embodiment, and both ends of the outer peripheral unit pipe bodies 31a, 31b, 32a, 32b. The parts are connected so as to be rotatable by pivotally supporting the parts.

  In this embodiment, as shown in FIG. 2, four first outer peripheral unit pipe bodies 31a, 31b and second outer peripheral unit pipe bodies 32a, having four equal lengths between a pair (two) of struts 2, 32b is coordinated. Each of the outer peripheral unit pipe bodies 31a, 31b, 32a, and 32b is composed of a linear rod-like body, and two of the outer peripheral unit pipe bodies 31a, 31b, 32a, and 32b are pivotally supported at bending points 31c and 32c as a set. It is combined to form a letter-shaped pipe unit. Therefore, two sets of pipe units are arranged between the pair of support columns 2. One side of the two sets of pipe units is connected to the upper end portion of the column 2 at the first connection point 31d as the first outer pipe unit 31, and the bending point 31c is lower than the first connection point 31d. The second outer peripheral pipe unit 32 is located on the other side, and the second outer peripheral pipe unit 32 is the first outer peripheral pipe unit 31 described above with respect to the sliding member 2a attached to the column 2 at the second connection point 32d. The first connection point 31d is connected so as to be positioned below the first connection point 31d, and the bending point 32c is positioned above the second connection point 32d. And in the intersection 3a where the 1st outer periphery pipe unit 31 and the 2nd outer periphery pipe unit 32 cross, each outer periphery unit pipe body 31a, 32a in each outer periphery pipe unit 31 and 32 is pivotally supported, and The outer peripheral unit pipe bodies 31b and 32b are pivotally supported so as to be rotatable. Therefore, in the present embodiment, the two intersections 3a are formed so as to sandwich one bending point 31c, 32c around each outer peripheral pipe unit 31, 32.

  In addition, each said outer periphery unit pipe body 31a, 31b, 32a, 32b is not restricted to the form shown in a present Example, For example, a curved rod-shaped body may be used, and each outer periphery pipe unit 31, The number of the outer peripheral unit pipe bodies per group of 32 may be increased to have a large number of intersections 3a and bending points 31c and 32c as shown in FIG. 12 showing a second embodiment described later. Contrary to the above, each outer peripheral pipe unit 31, 32 is constituted by one outer peripheral unit pipe body, and each outer peripheral pipe unit 31, 32 is pivotally supported by only one intersection 3a, "X" It is good as a type.

  Moreover, about each connection point 31d and 32d which exists in the connection location with respect to the support | pillar 2 of each outer periphery pipe unit 31 and 32, the 1st connection point 31d can be rotated via the bracket fixed to the upper end part of the support | pillar 2. As such, it is connected by means such as a shaft support. Further, the second connection point 32d is connected to a sliding member 2a slidably provided along the support column 2 so as to be rotatable by means such as a shaft support.

  In this embodiment, the sliding member 2a is a short cylindrical member provided so as to surround the outer periphery of the support column 2. The second outer peripheral pipe unit 32 is connected to the outside of the sliding member 2a. A bracket is provided. Further, a detachable fixing means is provided between the sliding member 2a and the support column 2, and fixing at the time of setting is performed. For example, for a hole formed on each side surface, a pin that can be inserted and removed is inserted, or a hole formed on at least one side surface of the support column 2 or the sliding member 2a. For example, by fitting a protrusion biased by a spring, which is coordinated to the other.

  The sliding member 2a is not limited to the above, but may be structured to be slidable with respect to the inside of the column 2 and provided with a bracket on the outside, and the second connection point 32d is slid along the column 2. If it can be moved, it can be changed into various forms.

  With the configuration as described above, in the present embodiment, the outer peripheral frame 3 is formed in a bellows shape, whereby each outer peripheral pipe unit 31 is moved along with the movement of the pair of struts 2 closer to or away from each other. , 32 can be changed, and the outer peripheral frame 3 can be expanded and contracted by being folded or expanded.

  And the outer periphery frame 3 comprises each side of the polygon which makes the position of the support | pillar 2 a vertex in planar view, and, thereby, the outer periphery shape of the tent 1 is prescribed | regulated.

  The reinforcing frame 4 is arranged inside the above-described polygon formed by the outer peripheral frame 3 so as to be directed toward the center thereof. The “center” is not a strict concept meaning the geometric center of the polygon, but has a meaning (wide concept) of about “one point inside the polygon”. In this embodiment, since the polygon is substantially square, as shown in FIG. 6A, the reinforcing frame 4 is located on a diagonal line in plan view. And the center support | pillar 5 is provided in the intersection of the reinforcement frame 4 which is the center of the said polygon, and the awning 6 is supported here. That is, the reinforcing frame 4 is arranged between the support column 2 and the center support column 5.

  In this embodiment, each reinforcing frame 4 is formed to have an equal length, but the present invention is not limited to this, and a combination of reinforcing frames 4 having unequal lengths may be used.

  In the conventional folding tent, as shown in FIG. 20, the reinforcing frame 104 is formed by connecting the outer peripheral frames 103 to each other. Therefore, in the polygonal portion formed by the outer peripheral frame 103, In order to provide strength against shear deformation, for example, it was necessary to separately attach a reinforcing material such as breath (not shown). On the other hand, in the present embodiment, the reinforcing frame 4 is formed on a substantially square diagonal line formed by the outer peripheral frame 3, so that the above-described strength is improved as compared with the conventional folding tent. Therefore, it is not particularly necessary to separately provide a reinforcing material. If a reinforcing material such as the reinforcing member 6 and the auxiliary reinforcing member 6 ′ shown in FIGS. 9 and 12 is provided, the strength can be further improved. it can.

  Since the structure of the reinforcing frame 4 is basically the same as that of the outer peripheral frame 3 described above, the difference from the outer peripheral frame 3 will be mainly described.

  As described above, the central column 5 is provided at the intersection of the reinforcing frames 4, and the awning 6 is supported here. In the tent 1 provided with the central column 5 as in the present embodiment, an inclination with the portion supported by the central column 5 as the apex is provided so that water does not collect on the awning due to rainfall during the construction. For this reason, it is desirable to coordinate the upper end part of the center support | pillar 5 to a higher place. However, unnecessarily extending the length of the central column 5 makes it difficult to stably support the awning 6 against wind or the like.

  On the other hand, as shown in FIG. 3, when the tent 1 is installed on a horizontal plane, the reinforcing frame 4 for the central column 5 compared to the column-side connection point 42 d existing at the connection point of the reinforcing frame 4 to the column 2. In the case where both the center side connection points 41e and 42e existing at the connection points are provided at high positions, the center column 5 can be stably supported. In addition, the space inside the tent can be expanded. Moreover, when the center support | pillar 5 is supported by the reinforcement frame 4 inclined as mentioned above, the length of the center support | pillar 5 can be made comparatively short, and the top part of the roof of the tent 1 is supported stably. can do.

  In addition, this invention is not limited to the structure where the center side connection points 41e and 42e of the reinforcement frame 4 as shown in FIG. 3 are high. For example, the column-side connection points 41d and 42d of the reinforcement frame 4 with respect to the column 2 and the center-side connection points 41e and 42e of the reinforcement frame 4 with respect to the center column 5 are provided at the same position in the vertical direction, that is, “ The reinforcing frame 4 may be such that the “bellows” extends in the horizontal direction.

  The reinforcing frame 4 is composed of a plurality of reinforcing unit pipe bodies 41 a, 41 b, 42 a, 42 b, as in the outer frame 3, and is combined so as to form a V-shaped pipe unit with two as one set. . The two sets of pipe units are arranged between the support column 2 and the center support column 5. However, unlike the outer peripheral unit pipe bodies 31a, 31b, 32a, and 32b of the outer peripheral frame 3, these reinforcing unit pipe bodies 41a, 41b, 42a, and 42b are not all equal in length.

  More specifically, as shown in FIG. 3, the set of reinforcing frames 4 arranged between the support column 2 and the center support column 5 includes a first support column side reinforcement unit pipe body 41a and a second support column side reinforcement unit. It consists of a pipe body 42a, a first center-side reinforcing unit pipe body 41b, and a second center-side reinforcing unit pipe body 42b. The first strut-side reinforcing unit pipe body 41a and the second strut-side reinforcing unit pipe body 42a are pivotally supported at the strut-side intersection 4a, and the first center-side reinforcing unit pipe body 41b and the second center-side reinforcing member are supported. The unit pipe body 42b is pivotally supported at the center side intersection 4b.

  As in the case of the outer peripheral frame 3, the first support-side reinforcing unit pipe body 41a and the first center-side reinforcing unit pipe body 41b are pivotally supported at a bending point 41c to form the first reinforcing pipe unit 41. The second strut-side reinforcing unit pipe body 42a and the second center-side reinforcing unit pipe body 42b are pivotally supported at a bending point 42c to constitute a second reinforcing pipe unit 42.

  Here, in the 1st reinforcement pipe unit 41, the length of the section which can be divided on the boundary between each intersection 4a, 4b and bending point 41c is made into the 1st section L1, the 2nd section L2, the 3rd section L3 from the support side. Assuming the fourth section L4, in the present invention, L1> L2, L2 = L3, and L3> L4, which are formed to become shorter toward the center side. This relationship is the same for the second reinforcing pipe unit 42. Therefore, the distance H1 between the column-side connection point 41d of the first reinforcement pipe unit 41 and the column-side connection point 42d of the second reinforcement pipe unit 42, the bending point 41c of the first reinforcement pipe unit 41, and the second reinforcement pipe unit. The relationship of the distance H2 between the bending point 42c of 42 and the distance H3 between the center side connection point 41e of the first reinforcement pipe unit 41 and the center side connection point 42e of the second reinforcement pipe unit 42 is H1> H2. > H3.

  The sum of the distance between the first connection point 31d and the intersection 3a and the distance between the second connection point 32d and the intersection 3a in the outer frame 3 and the column-side connection point 41d in the first reinforcement pipe unit 41 of the reinforcement frame 4 The distance between the column side intersections 4a (the first section L1) and the sum of the column side connection points 42d and the column side intersections 4a in the second reinforcing pipe unit 42 are formed to be equal, thereby The outer frame 3 and the reinforcing frame 4 are smoothly operated.

  On the other hand, the first reinforcing pipe unit 41 is connected to the column 2 so as to be rotatable at a column side connection point 41d at the upper end portion of the column 2, and to the center column 5 it is connected to the center column. 5 is connected to the center side connection point 41e of the upper sliding member 5a, which is located higher than the lower end of the column 5 and higher than the column side connection point 41d. The upper sliding member 5 a is the same as the sliding member 2 a provided on the support column 2.

  In addition, the second reinforcing pipe unit 42 is provided with respect to the support column 2 at a position closer to the lower side than the support column side connection point 41d with the first reinforcing pipe unit 41 (in this embodiment, the sliding member 2a). The outer peripheral frame 3 also shares this sliding member 2a.) And is slidably and pivotally connected at the column-side connection point 42d. It is a lower end portion, and is slidably and pivotably connected at a center side connection point 42e in the lower sliding member 5b provided at a position higher than the column side connection point 42d.

  This lower sliding member 5b is also the same as the sliding member 2a provided on the above-mentioned support column 2. Similar to the sliding member 2a, a detachable fixing means 5c is provided between the lower sliding member 5b and the central column 5, and the central column 5 is extended upward at the end of the tent construction, and then reinforced. A central column 5 is fixed to the frame 4. As a specific example of the fixing means 5c, as shown in FIG. 5, a pin that can be inserted / removed is inserted into a hole formed on each side surface, or the center column 5 or the lower sliding member 5b is inserted. , A protrusion formed by a spring, which is coordinated to the other side, may be fitted into a hole formed on at least one of the side surfaces. Can be implemented.

As described above, the central support column 5 slides with respect to the first reinforcing pipe unit 41 (connection at the center side connection point 41e) and also with respect to the second reinforcement pipe unit 42 (connection at the center side connection point 42e). Connected as possible. That is, the center column 5 is supported by the reinforcing frames 4 so as to be slidable in the vertical direction. As a result, the central column 5 can be moved up and down independently of each reinforcing frame 4, and after spreading each outer peripheral frame 3 and each reinforcing frame 4, only the central column 5 is moved upward with respect to each reinforcing frame 4. Can be moved to. That is, the central column 5 can be arbitrarily extended upward at the final stage of tent construction. By making the central column 5 such a structure, the length of the central column 5 is irrelevant with respect to the tent setting, and there is an advantage that the burden of the setting work can be reduced. In addition, for example, on a windy day, in some cases, it is possible to sufficiently respond to a user's request that only the apex portion of the awning 6 is separately raised after the outer peripheral frames 3 and the reinforcing frames 4 are finished.
Moreover, since there is no restriction | limiting in the height of the center support | pillar 5, there also exists an advantage that the shape of a tent can be designed more freely. Therefore, as shown in FIG. 1, it is easy to manufacture a tent of “Tongari roof”, which is characterized by having the top of the roof at a high position.

  Here, on the column 2 side, the column-side connection point 41d of the first reinforcement pipe unit 41 is provided at a position higher than the column-side connection point 42d of the second reinforcement pipe unit 42, and the center column 5 On the other side, the center connection point 41e with the first reinforcement pipe unit 41 is provided at a position higher than the center connection point 42e of the second reinforcement pipe unit 42.

  As described above, when the reinforcing frame 4 is folded or widened, the center connection point 41e of the upper sliding member 5a and the lower sliding member 5b slides along the central column 5 when the reinforcing frame 4 is folded or expanded. The column-side connection point 42d in the member 2a moves up and down along the column 2, but the movement length of each of the connection points 41e and 42d is closer to the column 2 side than the center column 5 side. Is getting bigger. Therefore, according to the lever principle, particularly when the tent 1 is set up, the central column 5 can be raised with a small force, the awning 6 can be easily stretched, and the tent 1 can be easily opened and closed. This is not limited to the case where each reinforcing pipe unit 41, 42 is composed of two reinforcing unit pipe bodies as in the present embodiment, but from three reinforcing unit pipe bodies as in the second embodiment described later. Even if it consists of reinforcing unit pipe bodies with more than that, it can have the same effect.

  In the present embodiment, the first strut-side reinforcing unit pipe body 41a and the second center-side reinforcing unit pipe body 42b are horizontally arranged with respect to the installation surface when the tent 1 is set up. Although this portion is designed to be 1 to 2 ° upward from the horizontal in design, it is actually caused by the self-weight of each reinforcing pipe unit 41 and 42 and the displacement due to long holes 41f and 42f (41h and 42h) described later. When tent 1 is set up, it is horizontal.

  On the other hand, the second strut-side reinforcing unit pipe body 42a and the first center-side reinforcing unit pipe body 41b combined with each of the reinforcing unit pipe bodies 41a and 41b described above are located on the installation surface when the tent 1 is installed. In this case, the configuration is inclined upward toward the center side.

  In the present invention, each of the reinforcing unit pipe bodies 41a and 42b is not limited to the horizontal arrangement as in the present embodiment, but may be implemented as being inclined downward toward the central direction. . Further, one of the reinforcing unit pipe bodies 41a and 42b may be horizontal or inclined downward. Accordingly, when the tent 1 is withdrawn, when the pair of support columns 2 are moved so as to be narrowed, the bending point 41c of the first reinforcing pipe unit 41 is smoothly bent downward.

  Here, a modified example of this embodiment is shown in FIG. 4 for comparison. This is different from the above-described structure shown in FIG. 3 in that the reinforcing frame 4 is formed upward. However, in this embodiment, there is a concern that when the tent 1 is withdrawn, the reinforcement pipe units 41 and 42 of the reinforcement frame 4 are bent when being caught. On the other hand, the structure of the reinforcing frame 4 as shown in FIG. 3 is advantageous because such a catch does not occur and the removal operation can be performed smoothly.

  Further, in this embodiment, the side view of the second reinforcing pipe unit 42 has a trapezoidal shape, is stable in strength, and stably supports the awning 6. Can do. Further, in this embodiment, as shown in FIG. 5, long holes extending in the longitudinal direction of the pipe bodies 41b and 42b are formed at the ends of the center-side reinforcing unit pipe bodies 41b and 42b on the side of the central column 5. 41f and 42f are formed, and the pipe bodies 41b and 42b are connected to the upper sliding member 5a at the center side connection point 41e through the elongated holes 41f and 42f, and at the center side connection point 42e. It is pivotally supported with respect to each column 5. That is, at each connection point 41e, 42e, it is pivotally supported so as to be movable along the longitudinal direction of each center-side reinforcing unit pipe body 41b, 42b, which is the direction intersecting with the center column 5.

  Here, the outer peripheral frame 3 is provided so as to coincide with a substantially square side in a plan view, whereas the reinforcing frame 4 coincides with a substantially square diagonal line, and the central support column. Since the whole is inclined toward the direction 5, the movement of the outer frame 3 and the reinforcing frame 4 when the tent 1 is set up and removed, specifically, the movement distances of the frames 3 and 4 when moving are different. . Therefore, if the support column 2 or the center support column 5 and the reinforcing frame 4 are simply connected so as to be rotatable, there is a case where a shift occurs and a smooth operation is not performed, or folding itself may be impossible. .

  Therefore, as described above, by providing the long holes 41f and 42f at the connection points 41e and 42e, the long holes 41f and 42f absorb the above-described deviation, and a smooth operation is performed. Therefore, the long holes 41f and 42f are an extremely important mechanism for folding the tent 1. In addition, the strength of the entire tent 1 is also increased.

  The dimensions of the long holes 41f and 42f may be appropriately set on condition that the displacement generated at the connection points 41e and 42e can be absorbed. When the diameter of the pin to be passed is used as a reference, 1.5 times to 10 times, preferably 2.5 times to 4 times is appropriate. Moreover, when expressed in dimensions, 3 mm to 30 mm, preferably 6 mm to 18 mm is appropriate.

  In contrast to the above, as shown in FIG. 6A, the I portion on the side of the center side connection points 41e and 42e is made into round holes 41f and 42f as shown in FIG. The II portion on the side of the side connection points 41d and 42d may be long holes 41h and 42h as shown in FIG. In addition, the case where the II portion is a long hole is more advantageous than the case where the I portion is a long hole as described above, because the long hole can be formed shorter. In addition, long holes may be formed in both the I part and the II part, and as long as the reinforcing frame 4 is supported so as to be movable in the direction intersecting with the support column 2 or the center support column 5, it can be implemented in various forms. Is possible.

  Further, in the present embodiment, the long holes are provided on the side of the reinforcing pipe units 41 and 42. On the contrary, the side of the reinforcing pipe units 41 and 42 is provided with a round hole so that the support column 2 and the center are provided. Even if a long hole is provided on the side of the column 5 and is pivotally supported, the same effect can be obtained. Further, as long as the center side connection points 41e and 42e or the column side connection points 41d and 42d are pivotally supported, means other than the long holes may be used.

  As shown in FIG. 3, the center column 5 is supported by the reinforcing frame 4, and is a rod-like body coordinated in the vertical direction in this embodiment.

  Here, as already described, the center column 5 is supported so as to be slidable in the vertical direction (direction when the tent is set) with respect to the reinforcing frame 4. Thereby, when the tent is set up, the central column 5 can be extended upward from the tent frame independently of the outer frame 3 and the reinforcing frame 4, and the awning 6 as shown in FIG. Form tents can be set up easily. From this, the design of the tent form can be made more freely.

  Although the central support column 5 of this embodiment is a single bar, it may have a telescopic structure. As a specific example, like the support column 2, a telescopic type in which a small-diameter rod-shaped body is accommodated inside a large-diameter hollow rod-shaped body, or a hinge can be provided at the joint between the rod-shaped bodies to enable folding. One that can be added by fitting rod-shaped bodies together.

  The sheet-like awning 6 is arranged so as to cover each of the support column 2, the outer peripheral frame 3, and the central support column 5, and the portion of the central support column 5 becomes the top of the roof of the tent 1.

  Next, a method for setting up the tent 1 according to the present embodiment will be described. First, what is in a folded state as shown in FIG. 7 is arranged so that the portion of the column 2 is in the vertical direction. In FIG. 7, the description of the awning 6 is omitted for explanation.

  And the support | pillar 2 is expanded radially, ie, the front-back, left-right direction. As a result, the outer peripheral frame 3 and the reinforcing frame 4 that have been folded into a bellows shape are expanded (extend). As described above, the reinforcing frame 4 of the present embodiment is formed obliquely upward as it goes in the center direction. Therefore, as the reinforcing frame 4 is expanded, the central column supported by the reinforcing frame 4 at the center. 5 rises upward. However, since the central column 5 is slidable by the reinforcing frame 4 at this time, the central column 5 is not yet extended upward as shown in FIG. The part that supports is only moved upward in the course of the event. Therefore, at this time, since the force for lifting the central column 5 is not necessary, the outer peripheral frame 3 and the reinforcing frame 4 can be expanded regardless of the length of the central column 5. The center column 5 assembles the tent frame as shown in FIG. 3 by expanding the outer peripheral frame 3 and the reinforcing frame 4 and then pulling it upward separately. As a result, the awning 6 attached to the support column 2, the outer peripheral frame 3, and the center support column 5 in advance is stretched. Then, if necessary, the column 2 is extended to lift the roof on which the awning 6 is stretched. By these operations, the tent 1 is set up.

  The lower end portion of the column 2 may be merely placed on the installation surface such as the ground, but in order to prevent it from moving due to wind or the like, a peg or the like is attached to the installation surface. It may be fixed by driving in, or the weights may be stacked.

  As described above, the folding tent 1 according to the present invention can be easily set up only by expanding the support 2 as described above, and can be set up by at least two persons.

  The withdrawal of the tent 1 may be performed in the opposite manner to the above-described setting method. In the installed state, the rod-shaped bodies constituting the column 2 are fixed by pins or the like (in the case of a combination of a plurality of rod-shaped bodies such as a telescopic type) or between the column 2 and the sliding member 2a. Therefore, cancel this and do the withdrawal work.

  Here, as described in the section of the reinforcing frame 4, the first strut-side reinforcing unit pipe body 41 a and the second center-side reinforcing unit pipe body 42 b are horizontal to the installation surface when the tent 1 is installed. Therefore, when the support 2 is narrowed when the tent 1 is withdrawn, the bending point 41c of the first reinforcing pipe unit 41 is bent downward so that the withdrawal operation can be performed smoothly. it can.

  The material of the support column 2, outer peripheral frame 3, reinforcement frame 4 and center support column 5 of the folding tent 1 according to the present invention includes various materials such as steel, aluminum alloy, plastic subjected to rust prevention treatment such as painting and plating. Can be used. In this embodiment, a hollow square pipe is used, but a round pipe or the like may be used. In addition, a light material such as plastic may be solid instead of a pipe. As described above, considering the weight, strength, durability, cost, etc., the most suitable material is adopted according to the purpose and customer's request.

  Although the above structure is sufficient in strength, a reinforcing member 6 for connecting the outer peripheral frame 3 and the central column 5 is added to the tent 1 of this embodiment as shown in FIGS. By providing it, the strength may be further increased.

  The reinforcing member 6 in the form shown in FIG. 9 is a rod-shaped body having one end connected to the upper sliding member 5a and the other end connected to a bending point 31c on the lower side of the outer peripheral frame 3 as shown in FIG. When the tent 1 is folded, as shown in FIG. 10, one end side is raised and the other end side is lowered.

  Further, the reinforcing member 6 having the form shown in FIG. 12 can be bent and bent into a V shape at a bending point 6a. Among them, the reinforcing member 6 arranged in parallel with the long side of the outer peripheral frame 3 is connected to the upper sliding member 5a on one end side and to the intersection 3a located on the short side of the outer peripheral frame 3 on the other end side. The reinforcing member 6 arranged in parallel with the short side of the outer peripheral frame 3 has one end on the upper sliding member 5a and the other end on the upper bent point 31c in the center of the long side of the outer peripheral frame 3. It is connected. When the tent 1 is folded, the reinforcing member 6 is lowered at the bending point 6a as shown in FIG.

Note that the reinforcing members 6 of both forms can be applied to both the tent 1 of this embodiment (see FIG. 9) and the tent 1 of the second embodiment described later (see FIG. 12).
The reinforcing member 6 may be formed in an accordion shape like the outer peripheral frame 3 and the reinforcing frame 4 described above.

  In addition to the reinforcing member 6, an auxiliary reinforcing member 6 ′ may be further provided as shown by dotted lines in FIGS. 6A, 9, and 12. The auxiliary reinforcing member 6 ′ shown in FIG. 9 has one end connected to the upper sliding member 5a and the other end connected to the intersection 3a of the outer peripheral frame 3. The auxiliary reinforcing member 6 ′ shown in FIG. The other end side of the upper sliding member 5 a is connected to the bending point 32 c of the outer peripheral frame 3. The auxiliary reinforcing member 6 ′ can be variously changed in the same manner as the reinforcing member 6, such as a single rod-like body, a member that can be bent into a V shape, and a bellows-like member.

  In the reinforcing member 6 shown in FIG. 12, a stopper 6b is provided so as to cover the bending point 6a, and the reinforcing member 6 is fixed by sliding the stopper 6b along the reinforcing member 6. The state and the bendable state can be switched, and the reinforcing member 6 is prevented from being bent carelessly during the setting of the tent 1.

  In this embodiment, the support column 2 and the outer frame 3 are formed so that the plan view is substantially square. However, the present invention is not limited to this, and as shown in FIGS. 2 can be implemented by connecting a plurality of tents 1 shown in FIG. 2 (continuous building type) with various polygons such as rectangles and hexagons so as to share sides. Moreover, it is good also as a structure which provided the member for connection etc. so that the some tent 1 can be connected and used only when needed, and it can implement in various changes.

  Here, the tent 1 is not a continuous building type shown in FIG. 11 as described above, but a single building type similar to that shown in FIGS. 1 and 2, and has a rectangular shape in plan view. A second example of the embodiment of the present invention will be described. FIG. 12 is an explanatory view showing the structure of the tent 1 in this embodiment, and FIG. 13 is an explanatory view showing the structure of the reinforcing frame 4. Note that the structure of the tent 1 of the second embodiment is basically the same as that of the first embodiment, and therefore, differences from the first embodiment will be mainly described.

In the second embodiment, since the length of the long side in plan view is longer than the length of the short side, the outer peripheral pipe unit for the outer peripheral frame 3 on the long side is compared with the first embodiment. The number of components 31 and 32 has increased. Specifically, as shown in FIG. 12, two sets of outer peripheral pipe units 31 and 32 are used between a pair (two) of struts 2, For each outer pipe unit 31, 32, there are four intersections 3a and three bending points 31c, 32c.
Similarly, the reinforcing frame 4 positioned on the diagonal of the rectangle also has a larger number of reinforcing pipe units 41 and 42 than the first embodiment. Specifically, as shown in FIG. A first strut-side reinforcing unit pipe body 41a, a second strut-side reinforcing unit pipe body 42a, a first intermediate-side reinforcing unit pipe body 41b, a second intermediate-side reinforcing unit pipe body 42b, a first center-side reinforcing unit pipe body 41g, Each of the second center-side reinforcing unit pipe bodies 42g. The first strut-side reinforcing unit pipe body 41a and the second strut-side reinforcing unit pipe body 42a are strut-side intersections 4a, and the first intermediate-side reinforcing unit pipe body 41b and the second intermediate-side reinforcing unit pipe body 42b are At the middle intersection 4b, the first center-side reinforcing unit pipe body 41g and the second center-side reinforcing unit pipe body 42g are pivotally supported at the center-side intersection 4c, respectively. The first strut-side reinforcing unit pipe body 41a, the first intermediate-side reinforcing unit pipe body 41b, and the first center-side reinforcing unit pipe body 41g are pivotally supported at the bending points 41c and 41c so as to be rotatable. A unit 41 is configured, and the second support-side reinforcing unit pipe body 42a, the second intermediate-side reinforcing unit pipe body 42b, and the second center-side reinforcing unit pipe body 42g are pivotally supported at bending points 42c and 42c. A second reinforcing pipe unit 42 is configured.

  Here, as in this embodiment, when the inventor of the present application prototyped a tent 1 in which the length of the short side and the long side of the outer peripheral frame 3 is different, If the column 2 is not moved and folded at the same distance as the side, the reinforcement frame 4 may be caught in the middle and may not be folded smoothly, or the folding itself may not be possible. As it is, it was very unusable.

  In order to solve this problem, in the second embodiment, the end portions of the first reinforcing pipe unit 41 and the second reinforcing pipe unit 42 in the reinforcing frame 4, respectively, on the support column 2 side and the center support column 5 side. In addition to those of the first embodiment, the end connecting portion 7 (see FIG. 14) is configured to swing freely, that is, moveable within a predetermined range in the circumferential direction with reference to the support column 2 or the center support column 5. It has a play that can be moved. Specifically, as shown in FIG. 14, the end connection portion 7 has a tapered wedge shape, and as shown in FIGS. 15A and 15B, the end connection portion 7 is formed so as to penetrate the end connection portion 7. It is pivotally supported with the support column 2 or the center support column 5 through the long hole 7c. The wedge-shaped configuration has a parallel surface 7a parallel to the longitudinal direction of each of the unit pipe bodies 41a, 42a, 41g, 42g having the end connection portion 7 on one side of the end connection portion 7. The other side has an inclined surface 7b which is a flat surface such that the distance from the parallel surface 7a becomes smaller toward the end side. The long hole 7c is the same as the long holes 41f and 42f described in the first embodiment, and is formed in a direction perpendicular to the parallel surface 7a, and each unit pipe body 41a, 42a, 41g, 42g. The shape extends in the longitudinal direction.

  Also, the column-side connection point 41d of the first reinforcement pipe unit 41 with respect to the column 2 and the center-side connection point 41e with respect to the center column 5 and the column-side connection point 42d with respect to the column 2 of the second reinforcement pipe unit 42 and the center column 5 are connected. In each of the center side connection points 42e, brackets 21 and 51 are provided on each of the column 2, the column-side sliding member 2a, the center column 5, and the center column-side upper sliding member 5a. As shown in FIGS. 14 and 16, the brackets 21 and 51 have opposing one-side inner surfaces 21a and 51a and the other-side inner surfaces 21b and 51b, and are supported between the inner surfaces. The above-mentioned end connection portion 7 similarly arranged between both inner surfaces is pivotally supported by the shafts 21c and 51c so as to be rotatable.

  Due to the shape of the end connection portion 7 and the shaft support through the long hole 7c, the reinforcing frame 4 can be attached to the inner surfaces 21a, 51a of the brackets 21, 51 and the end connection portion 7 as shown in FIG. From the state in which the parallel surface 7a abuts and the other side inner surfaces 21b, 51b and the inclined surface 7b of the end connecting portion 7 have a gap, as shown in FIG. 16, the one side inner surface of the brackets 21, 51 21a, 51a and the parallel surface 7a of the end connecting portion 7 have a gap, and the neck is in a range until the other side inner surfaces 21b, 51b contact the inclined surface 7b of the end connecting portion 7. Since the tent 1 can be folded, it can be folded smoothly even when the ratio of the movement distance of the column 2 is not the same as the ratio of the short side to the long side. be able to. Therefore, the end connecting portion 7 having such a shape is an extremely important mechanism for folding the tent 1. In addition, the strength of the entire tent 1 is also increased.

  In the second embodiment, the wedge-shaped end connection portions 7 as described above are provided on both the support column 2 side and the center support column 5 side. It is good also as what provided this terminal connection part 7 only in the 5 side or any one.

  In addition, said structure exhibits an effect similarly, even if it exists in a square tent in planar view like 1st Example. Further, the above is not limited to a rectangle, but can be applied to a tent 1 having various other polygonal shapes, and can be flexibly handled according to the purpose of use of the tent 1. Further, in FIG. 12, it is assumed that the reinforcing member 6 that connects the outer peripheral frame 3 and the central column 5 is provided. However, as already described, in the present invention, the presence or absence of the reinforcing member 6 does not matter. The reinforcing member 6 may be omitted, or conversely, an auxiliary reinforcing member 6 ′ may be further provided as indicated by a dotted line in FIG.

  Next, as a third embodiment, a reinforcing frame 4 is arranged in the same manner as the conventional tent shown in FIG. 20, and is independent of the outer peripheral frame 3 and the reinforcing frame 4 as in the above embodiments. Then, a description will be given of a structure provided with a central support column 5 that can be moved up and down (not shown).

  In the tent 1 of the present embodiment, as shown in FIG. 18, the bellows-shaped outer peripheral frame 3 is provided so as to connect the columns 2 to the columns 2 extending upward from the installation surface such as the ground. The outer peripheral frames 3 are connected to each other by a reinforcing frame 4, and the planar view has a “field” shape. This is the intersection of the reinforcing frames 4, and each of the above-described points is formed at the center of the polygon formed by the outer peripheral frame 3. Similar to the embodiment, there is provided a central column 5 that can be moved up and down independently of each reinforcing frame.

  Even in the tent 1 of the present embodiment, as in each of the embodiments described above, when the outer peripheral frame 3 and the reinforcing frame 4 are expanded, the force required to lift the central support column 5 is not necessary, so that the installation work is easy. Moreover, the length of the center column 5 can be freely set. Therefore, there is an advantage that the shape of the tent can be designed more freely.
