Description

  The present invention relates to a frame structure of a folding tent.

  Various folding tents are known, but the present invention is based on a top frame frame that is pivotally connected between columns with a plurality of cross scissors that are pivoted in a scissor shape, and a central portion located in the center of the top frame frame. It is equipped with a foldable ceiling frame that is radially formed, and is folded by constricting the column in the center of the column, expanding the column radially, and using a tent curtain to tie the framework structure of the folding tent Is.

  The ceiling frame in the frame structure of this type of folding tent has a structure in which the center side end of a bi-fold support rod connected and connected without using a cross rod is pivotally connected to a radiation connecting member (Patent Document) 1) A structure in which a cross column is used, a central column is provided in the center, and the center side end of the cross column is pivotally connected to a radial connecting member that is provided on the central column so that it can be moved vertically. Further, in the latter, there are known a structure in which the other end of the cross rod is pivotally connected to the midpoint of the top frame (Patent Document 2) and a structure in which the pillar is pivotally connected to each column. (Patent Document 3).

  If a force is applied from the outside to the center, that is, in the folding direction, in a state where the column is expanded to stretch the tent curtain, the tent frame structure is immediately distorted. For this reason, a pile stopper foot is provided at the lower end of the support column, and the support column is fixed to the ground by pile driving, but lacks stability when the tent frame is expanded.

  In particular, when a central support column is employed, one of the upper and lower two-stage radiation connecting portions (the lower stage in Patent Documents 2 and 3) is fixed. For this reason, when the framework is expanded, the column protrudes upward or downward, and if it protrudes upward, the center of the tent curtain is lifted, but if the tent curtain is separated from the ceiling frame and affected by wind, I'll be struck. Moreover, if it protrudes below, it will hang down in the space in a tent, and the tent itself will be difficult to use.

  Therefore, the present invention proposes a novel folding tent framework structure that is stable when the framework is expanded and has a central column, but the central column is vertically expanded and contracted.

  A folding tent according to the present invention (Claim 1) includes a column that is erected on the outer periphery of the tent, a ceiling frame that is axially connected between columns by a plurality of cross rods that are pivoted in a scissor shape, A ceiling frame that is formed radially from the center of the frame and folds and expands in conjunction with the top frame. The column is folded by narrowing the column toward the column center, the column is expanded radially, and a tent curtain is attached. In the framework structure of the folding tent used, the central part is composed of a central support column with a telescopic structure for inserting the inner and outer pipes, and a radiating connector provided at the upper and lower ends of the inner and outer pipes, and the ceiling frame is folded. Provide a releasable fixed locking mechanism that pivots the center side end of the ceiling frame whose vertical distance changes with extension to each of the upper and lower radiating connectors, and fixes the expansion and contraction movement of the inner and outer pipes at maximum expansion It is characterized by.

  Thus, when the struts are expanded in a direction away from each other, the top frame and the ceiling frame are extended, and at the same time, the vertical distance at the center side end of the ceiling frame is narrowed, and the inner pipe at the center is inserted into the outer pipe. When the inserted inner pipe and the outer pipe are fixedly locked at the time of maximum expansion, the whole is fixed in a state of maximum expansion.

  Since the ceiling frame connects the top of the column and the top of the central column, the roof surface of the tent curtain comes into contact with the ceiling frame, and the tent curtain is attached by appropriate means (for example, a fastening band provided on the tent). It can be securely attached to the ceiling frame.

  Further, the folding tent according to the present invention (Claim 2) is a movable locking body having a lever structure in which a fixed locking mechanism is pivotally connected to a radiation coupling body provided at the lower end of an inner pipe disposed below at an upper and lower intermediate portion. And a locking hook provided at the lower end of the outer pipe disposed above, and the movable locking body opens the upper locking claw and the locking claw locked to the hook. It has a lower operation part, and urges the locking claw in the closing direction, and the upper inner surface of the locking claw is formed as an inclined surface whose upper end reaches the outer periphery from the outer periphery of the collar part. .

  When the framework is expanded, the inner pipe at the center rises and is inserted into the outer pipe. When the upper inner inclined surface of the movable locking body comes into contact with the outer periphery of the locking collar, the inner pipe rises. As a result, the legs are opened against the urging force, and the locking claw is locked to the locking collar when the maximum opening is achieved. Accordingly, when the framework is expanded to reach the maximum spread state, the fixing and locking mechanism automatically operates to set the framework in a fixed state. Further, when folding during storage, the operating portion of the movable locking body is picked to release the locking.

  Further, the folding tent according to the present invention (Claim 3) is provided such that the outer peripheral side end of the ceiling frame is pivotally connected to the upper end fixed coupling body and the downward movement coupling body provided at the pivot coupling position of the cross frame of the ceiling frame frame in the column. By connecting the hem side of the ceiling frame to the column without using the shaft connection part of the cross frame of the ceiling frame frame, the roof framework structure becomes a plane triangular structure, and it will be firmly formed, And the number of combinations of cross folds is not limited to an even number.

  In the folding tent according to the present invention (Claim 4), the ceiling frame is folded in half between the main support rod which is folded in correspondence with the height of the column in the folded state, and the bottom main support rod. It consists of a hem-side reinforcement rod that is pivotally connected to the connecting body, and a ridge-side reinforcement rod that is pivotally connected between the middle of the ridge-side main support rod and the lower radiation connection body. Since the scissors-shaped cross 杆 is not used, it is possible to make it compact when folded. Regardless of the length of the main support rod (even if it is divided into the same length considering the folding time) The length can correspond to the vertical width of the top frame frame end interval, and can correspond to the vertical expansion / contraction length of the central column.

  The structure of the present invention is as described above, and in the tent frame that is folded by the expansion and confinement operation of the support column, the center support column that has a telescopic function at the center part and the center column at the time of maximum expansion when in use It is equipped with a fixed locking mechanism that fixes the expansion and contraction movement of the column, which improves the stability of the framework during use, and the central column does not protrude upward, so the tent curtain can be easily tried on the ceiling frame This can prevent flickering of the tent curtain.

Structural drawing of the center column (in use) Explanatory drawing of the fixed locking state. Explanatory drawing of the state at the time of the fixed latch release.

  Next, an embodiment of the present invention will be described. The framework structure of the folding tent shown in the embodiment is to shift from the use state to the folded state by the opening and closing operation of the support column. The support column 1, the ceiling frame frame 2, the ceiling frame 3, the central support column 4, and the fixed The locking mechanism 5 is used.

  The support column 1 is erected at the four corners of the tent. The support column 1 includes a pipe-shaped main support column 11 and an extending support column 12 provided so that the main support column 11 can be pulled out and fixed freely. In this, a fixed connecting body 13 is provided, and a moving connecting body 14 that can be moved up and down is provided below.

  The fixed connecting body 13 and the moving connecting body 14 are diagonally connected to a bearing portion provided at an angle of 90 degrees for pivotal connection (pivot connection) of each end of the top frame 2 installed between the adjacent support columns 1. A bearing portion provided in a direction is provided, and a foot plate 15 having a pile hole is provided at the lower end of the extension column 12.

  The top frame 2 is a conventionally well-known structure, and is constructed by connecting the ends of a plurality of cross rods pivoted in a scissor shape, and spanning between the columns 1. The fixed connecting body 13 and the moving connecting body 14 are pivotally connected.

  The ceiling frame 3 has two main support rods (a hem-side main support rod 31 and a ridge-side main support rod 32) having a length substantially coincident with the height of the main support column 11, and a middle between the main support rods 31 and 32. It consists of two reinforcing rods (the hem side reinforcing rod 33 and the ridge side reinforcing rod 34) that are pivotally connected.

  The hem side main support rod 31 and the ridge side main support rod 32 are pivotally connected to each other so that they can be folded in two. The end of the hem side main support rod 31 is connected to the fixed connector 13 and the end of the ridge side main support rod 32 is. Are pivotally connected to the upper radiating connector 43, which will be described later, the end of the skirt side reinforcing rod 33 is connected to the moving connector 14, and the end of the ridge side reinforcing rod 34 is pivotally connected to the lower radiating connector 44, respectively. And between the central column 4.

  The central support column 4 has a telescopic structure in which the lower inner pipe 42 is inserted into the upper outer pipe 41, and an upper radiation connecting body 43 that connects the aforementioned ridge-side main support rod 32 is provided at the upper end of the outer pipe 41. A lower radiation connecting body 44 for connecting the ridge-side reinforcing rod 34 described above is provided at the lower end of 42.

  The fixed locking mechanism 5 is composed of a locking collar 51 provided at the lower end of the outer pipe 41 and a movable locking body 52 attached to the lower radiation coupling body 44. The locking collar 51 is movable. The outer peripheral end corresponding to the operation range of the stop body 52 is provided.

  The movable locking body 52 has a lever structure pivoted at the upper and lower intermediate portions, and is provided with a locking claw 53 to be locked to the locking collar 51 on the inner surface above the pivoting position. A spring that is urged to rotate so that 53 is closed in the center direction is incorporated, and an operation portion 54 that opens the locking claw 53 against the urging force is provided below the pivot position.

  Further, the inner side surface above the locking claw 53 is formed on an inclined surface 55 whose upper end reaches the outer periphery from the outer peripheral edge of the locking collar 51.

  Thus, in the folded state, as shown in FIG. 2, the support column 1 is narrowed, and the top frame frame 2 and the ceiling frame 3 are pivotally stored at the pivot connection point. When the support column 1 is expanded in the direction away from each other in use, the top frame 2 and the ceiling frame 3 extend, and at the same time, the center side end of the ceiling frame 3, that is, the end of the ridge side main support rod 32 and the ridge side reinforcement rod 34. , The inner pipe 42 rises and is inserted into the outer pipe 41.

  When the support pipe 1 is further expanded and the inner pipe 42 is lifted and the upper inclined surface 55 of the movable locking body 52 is brought into contact with the outer peripheral edge of the locking collar 51, the biasing force is increased as the inner pipe 42 is lifted. When the locking claw 53 opens and the tent framework reaches its maximum extent, the locking claw 53 crosses the outer peripheral edge of the locking collar 51 and closes with a biasing force to the locking collar 51. Locked.

  Therefore, when the strut 1 of the tent frame is expanded and expanded to the maximum when the frame is in use, the fixed locking mechanism 5 automatically operates to lock the central column 4 so that it does not extend. . That is, the prevention of the extension of the central support column 4 also prevents the top frame 2 from being shortened, and at the same time prevents the top frame 2 from being shortened, so that the entire skeleton is fixed.

  Also, when folding during storage, if the operation part 54 of the movable locking body 52 is grasped with a finger to release the locking and the inner pipe 42 is slightly pulled down, the entire frame is fixed and the column 1 is moved as it is. The state of FIG. 2 can be restored by constricting.
