Description

  The present invention relates to a roof structure of a foldable tent that constitutes a framework such as a tent and an awning, and particularly relates to a roof structure having a wife surface.

  Conventionally, tents that support the roof curtain with a column called a canopy or tarp are installed with the roof curtain tensioned with a column and a string, and the tent is spread out in an umbrella shape around the apex, and the base is supported by the column Alternatively, a roof curtain support structure is provided to reduce the slack of the roof curtain due to the weight of rainwater or the like. In particular, a representative example of a tent provided with a roof curtain support structure is the one disclosed in Japanese Patent Publication No. 2836956 (Patent Document 1).

  This conventional tent is supported by four upstanding legs (posts), a scissor assembly (truss means) spanned between the upstanding legs, and a roof support member for forming the apex of the tent. It is composed of a central post, and supports the hypotenuse connecting the corners of the quadrangular pyramid to each corner of the base with a rope, and the edge of the roof curtain forming the side of the plane figure is supported by the upper end of each column. It has a structure that supports.

  For this reason, only a comparatively small tent can be produced, and it has been difficult to form a tent having a large size or a rectangular shape. Therefore, a tent as shown in Japanese Patent Laid-Open No. 2005-002699 (Patent Document 2) has been developed. The tent is a relatively large tent, but rainwater dripping from the four sides of the roof when used in rainy weather. For this reason, when a plurality of tents are arranged close to each other, rainwater falls between the tents. As a result, there is a disadvantage that a continuous roof space cannot be secured even if a plurality of tents are arranged.

  Therefore, an assembled tent having a wife surface is desired so that the roofs are continuous when arranged. However, in this type of assembly-type tent, in order to place importance on portability, it is common to use a member that is relatively light and has low bending strength for the roof structure and the support column. Therefore, if the frame is erected from the roof structure to form the end face, the weight of the stretched curtain is applied to the apex of the frame erected on the end face, and the frame is located on the center side of the roof structure. The problem that it will bend is generated.

Japanese Patent No. 2836956 Japanese Patent Laid-Open No. 2005-002699

  Although this invention is a portable folding tent that uses relatively lightweight and low bending strength members for roof structures and columns, it always goes directly to the roof, like a conventional steel pipe assembled tent. The purpose is to obtain a tent that has a wife face.

In order to solve the above-mentioned problems, the present invention employs at least four struts, a plurality of scissor assemblies that connect the struts so as to be foldable with each other, and a central portion of the curtain body at intervals. A plurality of curtain support poles that support the shape of the roof of the mold, and the scissor assembly has a structure in which two bars are pivotably connected in an X shape so that it can be folded into a pantograph shape. The curtain support pole is vertically connected to the center portion of the scissor assembly that connects the column in the short direction of the frame, and the fixed bracket fixed to the upper end of the column and the slide bracket that is slidably inserted in the column The support column and scissor assembly are connected to each other, and a fixed bracket fixed to the lower end of the curtain support pole and a slide bracket slidably inserted in the middle of the curtain support pole. Scissors In the roof structure connecting the assembly to one another, and curtain support poles to be installed in the center of the scissor assembly adjacent to the curtain support poles and the scissor assembly to be installed in the center of the scissor assembly outermost A reinforcing frame is detachably stretched between the ends, one end of the reinforcing frame is inserted into the upper end position of the outermost curtain support pole, and the other end of the reinforcing frame is inserted into the adjacent curtain support pole. At the position close to the slide bracket, it is locked to the curtain support pole, and the upper end of the curtain support pole is pushed upward by the reinforcement frame, and the slide bracket is pushed downward to assist the extension of the scissor assembly. While extending and improving the strength of the side, it is characterized in that it constitutes an upright wife face.

  In addition, the reinforcing frame is composed of two or more bar members and is extendable and contractible.

  Further, the reinforcing frame is provided with brackets having recesses substantially the same as the thickness of the curtain support poles at both ends, and the curtain support poles are sandwiched between the recesses and stretched between the curtain support poles and the slide brackets. It was set up.

  The reinforcement frame has a slide member with a spring incorporated in the vicinity of one end, and when stretched between curtain support poles, the reinforcement frame is pressed against and locked to the curtain support pole by the tension of the spring. It is characterized by that.

According to the present invention, the outermost curtain support pole of the roof structure, which forms the end face by the reinforcing frame, is stably supported without falling inward in an upright state. It can be kept upright against the two roofs along. Due to the presence of this wife surface, rainwater can be prevented from flowing down to the wife surface, and even when multiple folding tents are arranged in the longitudinal direction, rainwater can be prevented from dripping between the arranged tents. , It has an effect that a continuous space under the roof can be used effectively. In addition, since the two roof surfaces can be formed in a flat surface, there is an effect that a pattern, an advertisement, etc. applied to the roof surface can be displayed beautifully.

  A preferred embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing the installed tent (1), and FIG. 2 is a perspective view showing an outline of the roof structure. FIG. 3 is a transparent view in a state in which the curtain structure is covered with the roof structure, and FIG. 4 is a conceptual plan view of the roof structure. FIG. 5 is a view showing a reinforcing frame. FIG. 6 is a perspective view of one end portion of the reinforcing frame. FIG. 7 is a view showing a state in which the curtain support pole on the end face side and the reinforcing frame are locked. FIG. 8 is a view showing a state in which the slide bracket of the curtain support pole adjacent to the end face and the reinforcing frame are locked. FIG. 9 is a view showing a conventional folding tent.

  The roof structure is composed of columns (3) standing vertically at the four corners and the middle, a scissor assembly (2) horizontally connecting two adjacent columns, and a curtain support pole for extending curtains. Composed. The scissor assembly (2) has two bars pivotably connected in an X shape at the center so that it can be bent and stretched in a pantograph shape. The other end is fixed to the upper end, and the other one is slidably connected to the column (3) along the column. The curtain support pole (4) is fixed to the lower connecting portion of the scissor assembly (2) whose lower end is connected in the direction between the columns in the short direction, that is, in the direction parallel to the end face (7). When the scissor assembly (2) is extended, it is automatically lifted upward in accordance with the extension when the scissor assembly (2) is extended through a slide bracket inserted into the support pole (4). The curtain support pole (4) is covered with a curtain (6) made of a synthetic resin sheet or a woven fabric that has a desired waterproof strength and durability and is foldable to create a roof of the tent.

  FIG. 3 is a perspective view of a state in which the roof structure is extended and the curtain is covered. As shown in the figure, one end of the scissor assembly (2) is fixed to the upper end of the support column (3) through a fixing bracket (2a), and the other end is fixed to the support column through a slide bracket (2b) so as to be slidable. Has been. In addition, the upper and lower ends of the scissor assembly (2) are crossed and connected to each other at the connecting portion without the support column. The curtain support pole (4) is connected to the scissor assembly so that the column (3) is mounted upside down. That is, the lower end of the curtain support pole (4) is connected to the lower end of the scissor assembly (2) via the fixed bracket (2a), and is slidably fixed via the slide bracket (2b). Along with the extension of the solid (2), it is fixed so as to be lifted upward.

  As shown in FIG. 4, the roof structure has a structure in which four scissor assemblies (2) are connected in the longitudinal direction and two scissor assemblies (2) are connected in the short direction, and the center scissor assembly (2) is connected. The curtain support pole (4) is fixed at a position where they are connected to each other. Thus, when the roof structure is extended, the central column in the longitudinal direction is set as the apex. A tent having two roof surfaces and a wife surface (7) can be exhibited. A protective cap (41) is attached to the apex of the curtain support pole (4) so as not to damage the curtain (6) (see FIG. 7). The number of scissor assemblies (2), support posts (3), and curtain support poles (4) is not limited to this, and any number can be set.

  In a conventional tent, if the curtain (6) is to be displayed only with the scissor assembly (2) and curtain support poles (4a), (4b) and (4c), the weight of the curtain (6) The curtain support pole (4a) supporting the end face (7) is inclined toward the center of the roof structure, that is, the curtain support pole (4b) side. Therefore, in order to solve this problem in the present invention, as shown in FIGS. 3 and 4, the slide bracket (2b) positioned below the curtain support pole (4b) adjacent to the apex of the curtain support pole (4a). A reinforcing frame (5) is stretched at a position close to. As a result, the curtain support pole (4a) can be prevented from falling inward due to the weight of the curtain body (6), and the end face (7) standing upright with respect to the roof surface can be obtained. The reinforcing frame (5) is separate from the roof structure and can be removed arbitrarily.

  As shown in FIGS. 5 and 6, the reinforcing frame (5) is composed of a large-diameter bar (51) and a small-diameter bar (52) slidably inserted into the large-diameter bar (51). A fixing member (57) is attached in the vicinity of the connecting portion of 51) and (52) so as to be able to expand and contract. A slide member (53) is inserted into the open end of the small-diameter bar (52). The slide member (53) is constantly urged toward the open end of the small-diameter bar (52) by an internal spring (54). In the vicinity of the end of the small diameter bar (52), a long hole (not shown) along the longitudinal direction is drilled at the same place on the front and back, and a rivet (58) that penetrates the slide member (53) is provided here. The slide member (53) can slide on the small-diameter bar (52) by the length of the long hole. However, since the slide member (53) is urged toward the open end by the spring (54) as described above, the slide of the slide member (53) is only applied when a pressure against the spring (54) is applied. Is possible.

  A bracket (55a) for holding and locking the curtain support pole (4a) is fixed to one end of the slide member (53). The bracket (55a) has a generally U-shaped bent shape, and a locking recess (55c) processed into a substantially U-shape so that it can be locked while sandwiching the curtain support pole (4a) at the tip. ) Is formed. A protective cap (56) is fixed to the other end of the slide member (53). A bracket (55b) having the same shape as the bracket (55a) is also fixed to one end of the large-diameter bar (51). In the illustrated example, the brackets (55a) and (55b) are fixed by screws, and the protective cap (56) is fixed by insertion. It is not limited to this method.

  Next, a method for attaching the reinforcing frame (5) to the roof structure will be described. First, in order to make the reinforcing frame (5) to an appropriate length, the fixed member (57) is released from the stored state (FIG. 5a), and the large-diameter bar (51) and the small-diameter bar (52) can be slid to each other After this, the small diameter bar (52) is pulled out from the large diameter bar (51). The bars (51) and (52) are put into use (FIG. 5b) by fastening with a fixing member (57) with a specified length. Next, the bracket (55a) on the narrow bar (52) side of the reinforcing frame (5) is engaged with the curtain support pole (4a). As shown in FIG. 7, the lock is performed so that the upper end of the curtain support pole (4a) is held by the locking recess (55c) of the bracket (55a) in a state where the curtain (6) is extended. Since the protective cap (41) is fixed to the upper end of the curtain support pole (4a), the locking recess (55c) abuts the lower surface of the protective cap (41), and the curtain support pole (4a) ) Can be locked to the upper end of the curtain support pole (4a) without jumping out.

  After locking to the curtain support pole (4a), the large-diameter bar (51) is directed toward the small-diameter bar (52) and pressed and slid against the spring (54). Thereby, the narrow bar (52) enters the slide member (53), and the overall length of the reinforcing frame (5) can be shortened. Next, the locking recess (55c) of the bracket (55b) at the other end of the shortened reinforcing frame (5) is inserted into the slide bracket (4b) of the curtain support pole (4b) adjacent to the curtain support pole (4a). 2b) After setting to hold the vicinity, release the slide of the large diameter bar (51). Since the reinforcement bar (5) released from the slide restores its entire length by the force of the spring (54), the bracket (55b) moves downward along the curtain support pole (4b). At this time, the bracket (55) comes into contact with the slide bracket (2b) located on the support bar (4b), and the slide bracket (2b) is pushed down and locked. As a result, the reinforcement frame (5) is obliquely stretched between the curtain support poles (4a) and (4b), and the curtain support pole (4a) can be pushed out to the end face (7) side. Even if it is on the curtain support pole (4a), the wife surface (7) can be kept upright with respect to the roof surface.

  The tent (1) developed by the above procedure has a shape having two roof surfaces along the longitudinal direction and a wife surface (7) standing upright with respect to the roof surface as shown in FIG. Thus, since it has the wife surface (7) standing upright with respect to the roof surface, rainwater flows down only in two directions other than the left and right in the longitudinal direction, that is, the wife surface (7). Accordingly, even when a plurality of tents (1) are arranged in the longitudinal direction, rainwater does not fall between the tents, and a continuous roof space can be used. Further, since the roof surface can be formed into a flat surface, it is possible to display beautifully even when an advertisement or the like is given over a plurality of tents.

  It should be noted that at the time of storage, a portable state can be easily obtained by taking a procedure reverse to the procedure described above. First, slide the large-diameter bar (51) of the reinforcing frame (5) toward the small-diameter bar (52), remove the bracket (55b) from the curtain support pole (4b), and then remove it from the curtain support pole (4a). Remove the bracket (55a) and completely remove the reinforcing frame (5) from the roof structure. Next, the fixing member (57) is operated to shorten the reinforcing frame (5). In the roof structure, the four pillars (3) are moved closer to the center, so that the scissor assembly is compressed and folded to be stored. The curtain body (6) may be stored while attached to the roof structure or may be removed and can be arbitrarily selected.
