Description

  The present invention relates to a folding tent in which a roof is supported by a plurality of support columns, and more particularly to a so-called single-flow tent in which the roof is inclined from the front to the rear.

  A relatively tall column at the front and a relatively short column at the rear are erected, and these columns are connected to each other by a truss frame that rotates and expands in a scissor form to form a tent framework. A single-flow tent that is configured to be foldable so as to obtain a roof inclined from the front to the rear by attaching a tent to the frame is known. A single-flow tent having such a configuration is disclosed in, for example, Patent Document 1 and Patent Document 2.

The tents disclosed in Patent Document 1 and Patent Document 2 have a V-shape on the upper surface of the awning by cutting the sides of the awning into a wave shape according to the shape of the truss frame and sewing the upper surface sheet accordingly. A groove is formed, and the ridgeline of the groove is reinforced with a flexible reinforcing material such as a strip or a rope to prevent the awning from being slackened, and the central portion is prevented from drooping with rainwater. However, such a structure has a complicated structure of the awning, increases the cost, and is not supported by a rigid body, so it is impossible to avoid the occurrence of slack. It was a factor that accumulated.

FIG. 6 is a sectional view of the connecting means (6) for connecting the beam frame (2). The beam frame (2) is made of a pipe made of steel or resin.

  As shown in FIG. 1, the single-flow tent (1) configured to be freely expandable and foldable according to this embodiment is erected one by one at each of four corners of a flat rectangular ground plane (A). A total of four struts (7), a truss frame (3) that is spanned between the struts (7) and forms a rectangular frame as a whole, and a beam that is rotatably attached to the truss frame (3) The frame (2) is composed of a awning (9) (shown by a two-dot chain line in FIG. 1) mounted on a skeleton-shaped awning support structure (8) assembled by these frames. Of course, the installation form of the tent is not limited to a planar rectangle, but may be a square.

  The strut (7) has two tall struts (7a) at the front (in FIG. 1, a pair of struts on the left side toward the left) and the rear (right in FIG. 1, toward the right front). Two short columns (7b) are erected on each pair of columns, and the roof (10) extends from the front to the rear (in Fig. 1, the back) when the single-flow tent (1) is extended. It is configured to incline from the side to the front side. Each strut (7) has a pipe member (70) and a pipe member (71) having a smaller diameter than that of the pipe member (70), and the latter slides with respect to the former to have a desired length. It is configured to be fixed by (72) and is telescopic.

  A top bracket (12) to which one upper end (11) of the truss frame (3) is pivotally attached is fixed to the top of each column (7). Below the top bracket (12), a slide bracket (14) with one lower end (13) pivotally attached to the truss frame (3) is slidable with respect to each column (7). It is installed.

  The truss frame (3) has an X-shaped frame (17) that is pivoted into a scissor form with two rod-shaped frames (15) pivotally attached to each other by pins (16). Two or three of them are connected to each other by shaft attachment. As shown in FIGS. 1 and 2, an inverted V-shaped connecting portion (4) located above the X-shaped frame (17) of the truss frame (3) formed by connecting three X-shaped frames (17). Is mounted with a substantially U-shaped bracket (5) for pivotally connecting one end of the beam frame (2) to the connecting portion (4) (see FIGS. 3 to 5). ).

  The beam frame (2) divides the pipe material corresponding to the length of the tent in the depth direction and divides it into two parts, and connects them in the longitudinal direction to form a tent as a rod-like member having one rigidity. Support the center of the. At the free ends facing the beam frame (2), a connecting means (6) configured to be detachable is mounted (see FIG. 6) and connected to one through the connecting means (6). The tent of FIG. 1 includes two beam frames (2) arranged at intervals. The connecting means (6) is inserted on the side where the free end of one beam frame (2) is inserted into the free end of the other beam frame (2) to be connected and the connected state is maintained. The dowel (20) urged by the spring (19) protrudes from the through hole (18) penetrated in an appropriate part of the beam frame (2a), and this dowel (20) is inserted at the time of insertion. The dowel (20) protrudes from the through hole (21) penetrating the appropriate part of the free end of the beam frame (2b) on the side to be locked by the biasing force of the spring (19) to lock the connection state. ing. The release of this locked state can be achieved by pulling out and removing the beam frame (2a) that has been inserted while pushing in the dowel (20).

  The ends opposite to the free ends of the beam frames (2) are pivotally attached to the brackets (5) attached to the connecting portions (4) of the opposed truss frames (3), respectively. It is configured to be freely rotatable. When the single-flow tent (1) is stored, the beam frame (2) is separated into two by separating the beam frame (2), which has been made into one, at the connecting means (6). When the tent (1) is expanded, the beam frame (2) separated into two is connected via the connecting means (6) to be unified.

  The frame-shaped awning support structure (8) includes a pair of opposing short sides formed by two opposing truss frames (3) formed by connecting two X-shaped frames (17), and an X-shaped frame (17 ) Three truss frames (3) connected to each other, two truss frames (3) facing each other and a pair of long sides facing each other, a plane rectangular frame-shaped truss frame (3), and a truss frame (long side) 3) It is composed of two beam frames (2) which are bridged in the short side direction to form a beam. The tent supporting structure (8), which is supported by the four support columns (7) and deployed, is equipped with a awning (9) made of a sheet material to form a tent. The awning is folded and pre-booked in a state of being preliminarily mounted on the frame structure. For storage, the beam frame (2) is separated by the connecting means (6) and rotated downward to hang down, and the truss frame (3) is contracted while moving the columns (7) horizontally to bring them closer to each other. Further, each support (7) is shortened to obtain a compact storage state.

  FIG. 7 shows a modification of the beam frame, in which the beam frame (2) is composed of a single rod-like body, and downwardly U-shaped fitting brackets (50) are attached to both ends thereof. (50) is fitted to the inverted V-shaped connecting part of the truss frame (4), and is spanned between the truss frames (4) to support the central part of the awning (9) in a beam shape It is. Of course, the beam frame (2) is not limited to a single rod, but may be configured by connecting a plurality of rods into a single rod. .

  FIG. 8 shows still another modification of the beam frame. The beam frame (22) corresponds to the length of the tent in the depth direction, and has a structure in which two pipe members (22a) and (22b) are connected by a hinge portion (23). The hinge portion (23) has a structure in which one ends of two pipe members (22a) and (22b) are connected to each other by a pin, and the beam frame (22) can be bent around the pin. A stopper (24) is formed in the vicinity of the hinge portion of both pipe members (22a) and (22b), and one pipe member (22a) has a dowel as shown in FIGS. 6A and 6B. A lock button (25) having a structure is formed. Also, between the stoppers (25) and (25), a slide member (26) having a length capable of covering the hinge portion (23) and having a lock hole (26a) formed in the vicinity of the end portion is inserted. Yes.

  Next, the usage state of the beam frame (22) will be described. As shown in FIG. 9, both ends of the beam frame (22) are connected to the connecting portion (4) of the truss frame (3), and are incorporated as a part of the roof structure. The beam frame (22) becomes less bent as the roof structure is deployed, and extends in a straight line when fully deployed (see FIG. 8A). From this state, the slide member (26) is moved to the hinge portion (23), and further moved beyond the lock button (25) until the button (25) protrudes from the lock hole (26) (see FIG. 8B). . As a result, the hinge portion (23) and both side portions thereof are covered with the slide member (23), the bending of the hinge portion (23) is suppressed, and the straightly extended state is maintained. In addition, since the stopper (24) is formed in each of the pipe members (22a) and (22b), the slide member (26) does not slide the beam frame (22) unnecessarily.

  At the time of folding, contrary to the above procedure, first, the lock button (25) is pushed in and released from the lock hole (26a). Next, the slide member (26) is moved to the stopper (24) of the pipe material (22b), so that the hinge portion (23) can be bent. Further, the truss frame (3) is contracted while moving each column (7) in the horizontal direction to approach each other. At this time, the beam frame (22) is simultaneously folded inward of the truss frame while bending downward. Finally, each column (7) is shortened to obtain a compact storage state. Similarly to the beam frame (2), the beam frame (22) is attached with a downward U-shaped fitting bracket (50) at both ends, and the fitting bracket (50) is opposite to the truss frame (4). It may be fitted to the V-shaped connecting portion and spanned between the truss frames (4) to support the central portion of the awning (9) in a beam shape.

  In the illustrated embodiment, two pairs of struts (7a) and (7b) having different heights are employed and the roof (10) is inclined. However, the roof (10) is not necessarily a strut having a different height. It does not have to be tilted using (7), and may be horizontal. Of course, the configuration of the present invention is not limited to this point, and various modifications can be made without departing from the gist of the present invention.
