Description

  The present invention relates to a tent for rain protection and sun protection.

  As a kind of tent, a foldable tent that can be assembled with one touch is known (see Patent Document 1). In this folding tent, a tent sheet is integrated with a folding tent frame in advance.

  The tent has a column member standing in four directions, a telescopic connection frame for connecting upper portions of the column members, and a top provided with a tent sheet support surface at an upper end disposed in a space surrounded by the column members. A column, a telescopic top column support frame that supports the top column on the connection frame, and a tent sheet supported by the column member and the top column. The extension operation of the connecting frame causes the extension of the top column support frame, the rise of the top column, the dispersion of the column members in four directions, and the expansion of the tent sheet at the same time, so that the tent can be easily deployed. It can be in the state (installation state). On the other hand, due to the shrinking operation of the connecting frame, the top pillar support frame shrinks, the top pillar descends, the pillar members gather, and the tent sheet is gathered at the same time. State).

  In the conventional tent, in the case of rain, a water pool may be formed on the tent sheet. If water pools are formed on the tent sheet, an extra load is applied to the tent, which causes damage.

  Therefore, as shown in FIG. 15 of Patent Document 2, a configuration has been proposed in which the top column is configured to be extendable and adjustable so that the tension of the tent sheet can be adjusted as appropriate.

Japanese Patent No. 2625255 Utility Model Registration No. 3057223

  The thing of patent document 2 is the following structures. The top column that supports the tent sheet is divided into a lower cylinder and an upper bar-shaped tension member that is fitted into the cylinder from above. A drive screw shaft that can be rotated from the outside is disposed in the cylinder. An elevating plate that is screw-coupled to the drive screw shaft is disposed in the cylinder, and the tension device is elastically supported by a spring disposed on the elevating plate. The elevating plate is a square plate and is prevented from rotating in the cylinder having an internal space with a square cross section. For this reason, when the drive screw shaft is rotated from the outside of the cylinder, the elevating plate moves up and down in the cylinder, and the tension tool moves up and down via the spring. Thereby, the tension of the tent sheet can be adjusted.

  However, in the conventional configuration, since the drive screw shaft and the lifting plate are accommodated in the cylinder, the lifting stroke of the tension tool must be smaller than half the length of the cylinder. For this reason, the tension of the tent sheet can be adjusted within a small range, but it is not suitable for a case where the inclination of the tent sheet is to be changed greatly.

  This invention is made | formed in view of the above situations, and intends to provide a tent with a large expansion-contraction stroke of a top pillar.

  In order to solve the above problems, a tent according to the present invention includes a top column having a tent sheet support surface at an upper end, and a tent sheet supported by the top column, the top column being a lower top column and the top column. The upper top column is inserted into the lower top column, a rotation operation handle is disposed at the lower end of the lower top column, and a rotation axis driven by the rotation operation of the rotation operation handle is provided. A screw thread is formed over the entire length of the lower top column, and a screw thread is formed on at least the upper portion of the pivot shaft. And fixed in a non-rotatable manner (claim 1).

  According to the present invention, the rotation shaft is driven by rotating the rotation operation handle, and the upper top column moves up and down via the screw thread and the screw member. The pivot shaft is disposed over substantially the entire length of the lower top column, the screw thread is formed at least on the pivot shaft, and the screw member is disposed in the upper top column. Since it is fixed to be non-rotatable over almost the entire length, the upper top column is driven up and down over almost the entire length of the lower top column. For this reason, the inclination of a tent sheet | seat can be changed greatly by the expansion / contraction operation of a top pillar.

  A tent according to another embodiment of the present invention includes a top column having a tent sheet support surface at an upper end, and a tent sheet supported by the top column, the top column being a lower top column and the top column. The upper top column is inserted into the lower top column, a rotation operation handle is disposed at the lower end of the lower top column, and a rotation axis driven by the rotation operation of the rotation operation handle is provided. A screw member is disposed over substantially the entire length of the lower top column, and a screw thread is formed over substantially the entire length of the pivot shaft, and a screw member that is screw-coupled to the screw thread is at least a lower portion of the upper top column. It is fixed to be non-rotatable (claim 2).

  According to the embodiment, the rotation shaft is driven by rotating the rotation operation handle, and the upper top column moves up and down via the screw thread and the screw member. The rotating shaft is disposed over substantially the entire length of the lower top column, the screw thread is formed over substantially the entire length of the rotating shaft, and the screw member is the upper top column. Since it is fixed to at least the lower part in a non-rotatable manner, the upper top column is driven up and down over substantially the entire length of the lower top column. For this reason, the inclination of a tent sheet | seat can be changed greatly by the expansion / contraction operation of a top pillar.

It is a schematic perspective view of the expansion | deployment state of the tent frame which comprises the tent which concerns on one Embodiment of this invention. It is a perspective view of the state which folded the tent frame of FIG. 1 to about half. It is a longitudinal cross-sectional view of the top pillar in FIG. FIG. 4 is an enlarged view of a lower part of the top pillar in FIG. 3. It is a longitudinal cross-sectional view which shows the other Example of the top pillar of FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  First, with reference to FIG.1 and FIG.2, the whole structure of the tent based on this invention is demonstrated.

  A tent according to an embodiment of the present invention includes a tent sheet 30 (see FIGS. 3 and 5) and a tent frame 2. Although not shown in FIGS. 1 and 2, the tent sheet is attached to the tent frame 2 in advance.

  The tent frame 2 will be described. As shown in FIG. 1, the inner ends of two sets of outer beam members 4 and 4 in which two bars 3 and 3 are pivotally supported in an X shape are connected to each other. Joint portions 5 and 5 are formed between each other. This stretchable structure (the connecting frame 31) is disposed between four column members 6, 6, 6 and 6 standing at four corners at equal intervals, and is positioned above the outer beam member 4. The outer end portions 7 and 7 are pivotally attached to the upper end coupler 8 provided at the upper end of each column member 6. Outer end portions 9, 9 positioned below the outer beam member 4 are pivotally attached to slide members 10 that are fitted to the column members 6 so as to be slidable up and down. Further, the outer end portion 12 of the inner beam member 11 having the same configuration as the outer beam member 4 is pivotally supported by the joint portion 5. The inner end portion 13 located on the lower side of the inner beam member 11 is pivotally supported by a lower end connector 15 formed at the lower end of the top column 14. The inner end portion 16 located on the upper side of the inner beam member 11 is pivotally supported on the top support 17. The top pillar 14 is inserted into the top support 17 so as to be movable up and down. The inner beam member 11 is a telescopic top column support frame that supports the top column 14 to be movable up and down on the connection frame 31. As shown in FIG. 2, when the four column members 6 are collected, the slide member 10 is lowered along the column members 6, the joint portion 5 is folded, and the lower end connector 15. Descends. Eventually, the four column members 6 surround the top column 14 and they are concentrated in one place. This state is the storage state of the tent.

  In the tent setting state of FIG. 1, the tent sheet 30 is supported by the central top column 14 and the column members 6 at the four corners. In the tent storage state, the tent sheet 30 is gathered compactly on the tent frame 2 in accordance with the contraction / collection of the tent frame 2.

  When the tent is assembled, the slide member 10 is fixed to the upper portion of the column member 6. A lock hole (not shown) for fixing the slide member 10 is formed in the upper portion of the column member 6. A locking device 1 is provided to fix the slide member 10 so as not to move up and down with respect to the column member 6 at the position of the lock hole.

  Further, in order to enable compact storage of the tent frame 2, the column members 6 and the top column 14 are extendable. That is, as shown in FIG. 1, each of the column members 6 includes an outer cylinder member 21 positioned on the upper side and an inner cylinder member 22 that is inserted into the outer cylinder member 21 so as to be relatively stretchable. A plate-like underlay leg 23 that is grounded to the ground is fixed to the lower end of each column member 6, that is, the lower end of the inner cylinder member 22. Each of the column members 6 is in a maximum contracted state when the tent frame is folded and stored, and is extended and fixed to a predetermined length when the tent is assembled.

  On the other hand, as shown in FIG. 3, the top column 14 includes a lower top column 32 and an upper top column 33 that is inserted into the lower top 32 column so as to be relatively stretchable. Each of the lower top column 32 and the upper top column 33 is a hollow quadrangular column and has an internal space having a square cross section.

  A rotating operation handle 34 is disposed at the lower end of the lower top pillar 32. A rotation shaft 35 driven by the rotation operation of the rotation operation handle 34 is disposed over almost the entire length of the lower top column 32. A screw thread 36 is formed on at least the upper part of the rotating shaft 35. A screw member 37 that is screw-coupled to the screw thread 36 is fixed to be non-rotatable over almost the entire length of the upper top pillar 33. The outer peripheral shape of the screw member 37 is a quadrangular column, and the rotation is blocked by the inner wall of the upper top column 33.

  A tent sheet support surface 38 is formed at the upper end of the upper top pillar 33. The tent sheet support surface 38 has a smooth dome shape so as not to damage the tent sheet 30. A plug 39 having the tent sheet support surface 38 is screwed to the upper end opening of the upper top pillar 33. A stopper 40 for preventing the screw member 37 from coming off is formed at the lower end of the upper top pillar 33. The screw member 37 is inserted into the upper top pillar 33 from the upper end opening of the upper top pillar 33 and is prevented from being pulled upward by the plug 39.

  In FIG. 3, the screw member 37 is illustrated as a single bar, but may be divided into a plurality of elements in the middle of the vertical direction.

  As shown in an enlarged view in FIG. 4, the rotation operation handle 34 has a hollow cylindrical boss portion 41, and a spline portion 42 is formed on the inner peripheral surface of the boss portion 41. The spline portion 42 is fitted with a spline shaft 43 connected to the lower end of the rotation shaft 35. Therefore, the rotation shaft 35 can be driven to rotate by operating the rotation operation handle 34 to rotate.

  A bolt insertion hole 44 is formed on the lower surface of the boss portion 41 of the rotation operation handle 34. The lock bolt 45 inserted into the bolt insertion hole 44 is screwed into a screw hole 46 formed in the spline shaft 43. A grip 47 of the lock bolt 45 abuts on the lower surface of the rotation operation handle 34. Thereby, the rotation operation handle 34 is fixed to the spline shaft 43 so as not to be pulled out. When the screwing amount of the lock bolt 45 into the spline shaft 43 is increased, a part of the rotation operation handle 34 is pressed against the lower surface of the lower top column 32. Therefore, the rotation operation handle 34 and the rotation The shaft 35 is locked. By locking them, the load of the tent sheet 30 can counter the force that pushes down the upper top pillar 33.

  A bearing 48 is disposed in the lower portion of the lower top pillar 32, and the rotating shaft 35 is rotatably supported by the bearing 48. The spline shaft 43 connected to the lower end of the rotation shaft 35 is larger in diameter than the rotation shaft 35, and acts as a sock absorber between the upper end surface of the spline portion 43 and the bearing 48. A spring 49 is interposed.

  With the above configuration, the rotation shaft 35 is rotationally driven by rotating the rotational operation handle 34, and the upper top column 33 is driven up and down over almost the entire length of the lower top column 32. Is done. For this reason, as shown in FIG. 3, the inclination of the tent sheet 30 can be largely changed by the expansion / contraction operation of the top column 14. Of course, fine adjustment of the tension of the tent sheet 30 is also possible. By tightening the lock bolt 45, it is possible to prevent the turning operation handle 34 from rotating back due to the load or tension of the tent sheet 30.

  FIG. 5 shows another embodiment of the top pillar 14. 3 differs from that shown in FIG. 3 in that a screw thread 48 is formed over substantially the entire length of the rotating shaft 35, and a screw member 49 screwed to the screw thread 48 cannot be rotated at least in the lower part of the upper top column 33. It is to be fixed to. Also with this configuration, by rotating the rotation operation handle 34, the rotation shaft 35 is driven to rotate, and the upper top column 33 is driven to move up and down over almost the entire length of the lower top column 32. be able to. The other elements in FIG. 5 have the same configuration as that of FIG.
