Description

Tent structure having deflection prevent function

The present invention relates to a tent structure that serves as a skeleton of the tent, and more particularly, to a tent structure having a deflection prevention function to restore the deflection portion to the initial position by itself when the deflection caused by the vertical load.

For example, tents used for various outdoor events and camping are simple facilities for protecting users from direct sunlight, snow or rain. There are many types of these tents, and their structure may vary depending on the purpose of use, location of use, or season.

One common tent around life has four basic struts that are erected vertically, a horizontal rung that connects each strut, and a tent roof that covers the struts and rungs. The strut and the crosspiece are fixed using a connection part for connection to form a structure.

As shown, the conventional tent structure 10 is connected to the struts 11 through the four struts 11, the connector 13, a plurality of crossbars (15a, 15b) to maintain the horizontal, each crossbar ( It is erected at the intersection of the first wire 17 and the first wire 17 fixed to the support connecting portion 14, the support connecting portion 14 and the connector 13, which are fixed to the central portion of the 15a, 15b. The central column 16, the support connecting portion 14 and the second wire 18 is fixed to the upper end of each support (11).

The tent structure 10 serves as one support frame and supports the tent roof 19 covered thereon as shown in FIG. 2.

However, the above-described conventional structure 10 has a disadvantage in that it cannot actively cope with the vertical load applied to the cross bars 15a and 15b. For example, when the load in the direction of the arrow p is concentrated on the front support connecting portion 14, the crossbar 15a itself is bent, and, in severe cases, the crossbar 15a is separated from the connector 13 at all. It also becomes.

Although the second wire 18 is applied to prevent the deflection of the crosspiece, the second wire 18 does not play a role as expected. This is because the ring 14a connecting the second wire 18 and the support connecting portion 14 is weak and easily broken.

The same reference numerals as the above reference numerals refer to the same members having the same function, and repeated description thereof will be omitted.

As shown, the tent structure 30 having a sag prevention function according to the present embodiment, four struts 31, horizontal crossbars 32 fixed to the struts 31, wires provided in each crossbar Lifting wire 35 connecting the holder 37, the wire holder 37 and the upper end of the support 31, the first wire 17 fixed to the inner region of the crosspiece 32, the first wire 17 is supported It is provided with two central pillars 16, the sag detection unit 40 for detecting the sag of the crosspiece 32, the control unit 45, the drive unit 47.

First, the strut 31 is a hollow pipe-shaped member erected perpendicular to the ground and has a wire support 31a at its upper side. The wire support 31a is for connecting the lifting wire 35 to the upper end of the strut 31 and has a through hole 31b therefor. The lifting wire 35 is maintained in the state of being stretched taut while passing through the through hole 31b. In addition, the lifting wire 35 is capable of longitudinal movement while being supported by the wire support 31a.

In particular, as shown in an enlarged view in FIG. 3, one of the four pillars is provided with a wire induction pipe 33 at the upper end of the pillar. The wire induction pipe 33 is a member having an upper portion like a trumpet, and is led downward to both ends of the lifting wire 35 to the support 31. As will be described later, the lifting wire 35 is connected to the driving unit 47 inside the support 31 and is tensioned by the driving unit 47.

In order to smoothly move the lifting wire 35, the induction curved portion 33a is curved at the upper end of the wire induction pipe 33. The lifting wire 35 is slidable on the upper surface of the guide curve portion 33a.

Both ends of the crosspiece 32 are linked to the strut 31 through the connector 34. The ends of the connector 34 and the crosspiece 32 are connected to the support pins 34b. In addition, the crosspiece 32 itself is composed of a first side bar member 32a and a second side bar member 32d. In other words, the ends of the first frame member 32a and the second frame member 32d are connected by the link pin 32e. As a result, both ends of the first and second bar members 32a and 32d are connected to each other by the support pins 34b and the link pins 32e. ) Is folded and can be used by folding. The tent structure 30 of the present embodiment is folding.

The crosspiece 32 is naturally located at an altitude lower than the upper end of the strut 31. That is, it is to maintain the level at a lower altitude than the wire support (31a).

In addition, a wire holder 37 is installed on each crosspiece 32. The wire holder 37 is an accessory disposed close to the link pin 32e and can be positioned in the longitudinal direction of the crosspiece 32.

The wire holder 37 is composed of a hollow pipe type body portion 37a and a connecting portion 37b integrally formed on the upper portion of the body portion 37a. The main body portion 37a maintains the engagement state with the crosspiece 32 by passing the crosspiece 32 therein. As long as the lengths of the first and second rail members 32a and 32d are the same, the main body portion 37a may be located at either the first rail member 32a or the second rail member 32d.

The connecting portion 37b connects the lifting wire 35 to the wire holder 37 and has a horizontal wire passage 37c through which the lifting wire 35 passes. When the wire holder 37 tensions the lifting wire 35 in the direction of arrow a, the wire holder 37 is supported upward in the direction of arrow b under the force of the vertical component of the tension force. Of course, the upward bearing force in the direction of the arrow b acts to cancel the vertical load applied to the crosspiece 32.

Tensile steel wire made by twisting the lifting wire 35, steel wire or stainless steel wire, both ends of which are held through the wire guide pipe 33 in a state of sequentially passing through the wire passage 37c and the through hole 31b. 31 extends inwardly and is stretched in the direction of arrow a by the drive unit 47.

On the other hand, the sag detection unit 40 is provided between the first side bar member 32a and the second side bar member 32d. The deflection detecting part 40 serves to detect the deflection of the connection portion of the first and second bar members 32a and 32d downward. For example, the first and second bar members 32a and 32d sense bending by the vertical load applied to the crossbar 32.

The sag detection unit 40 includes a sensing and communication unit 41 and a counter block 43. When the sensing and communication unit 41 is installed in the first frame member 32a, the counter block 43 is located in the second frame member 32d, on the contrary, the sensing and communication unit 41 is in the second frame member 32d. When fixed to the counter block 43 is installed on the first side member 32a. Hereinafter, it will be described that the sensing and communication unit 41 is positioned on the first side member 32a and the counter block 43 is located on the second side member 32d.

5A and 5B are views for explaining the detailed configuration and operating principle of the deflection detecting unit 40 shown in FIG.

As shown in the figure, the deflection detecting unit 40 includes a sensing and communication unit 41 and a counter block 43 corresponding thereto.

The sensing and communication unit 41 is fixed to the lower portion of the first side bar member 32a and has an opening 41k, an anchor block which is installed to be movable in a position inside the sealing case 41a. 41b), the sensor actuating wire 41c fixed to the anchor block 41b and extending out of the sealed case 41a, the steel ball 41d fixed to the end of the sensor actuating wire, and the sensor actuating wire 41c are tensioned. And a piezoelectric element 41e and a transmission module 41f for generating a signal.

The sealed case 41a is an insulated box in which the anchor block 41b, the piezoelectric element 41e, and the transmission module 41f are built, and is detachably installed to the first side member 32a as necessary.

The anchor block 41b takes the form of a cube or plate and engages with one end of the sensor actuating wire 41c, and when the sensor actuating wire 41c is tensioned in the direction of the arrow d, it is pulled toward the opening 41k and piezoelectric. The element 41e is pressed.

The piezoelectric element 41e is disposed between the anchor block 41b and the inner wall surface of the sealed case 41a, and outputs an electric signal when pressed by the anchor block 41b. The electrical signal output from the piezoelectric element 41e is transmitted to the transmission module 41f, and the transmission module 41f transmits information to the controller 45 that pressure is applied to the piezoelectric element.

The counter block 43 is fixed to the lower portion of the second side bar member 32d and faces the sealed case 41a. The counter block 43 is provided with a wire slit 43a that is open to the side. The wire slit 43a accommodates the sensor operation wire 41c as a gap inclined downward toward the center of the counter block 43.

When holding the steel ball 41d and inserting the sensor operation wire 41c into the wire slit 43a, as shown in FIG. 5A, the steel ball 41d is caught by the counter block 43 so that the counter block 43 Located in the rear, the sensor operation wire 41c is kept in a taut state.

In this state, when the first and second bar members 32a and 32d are bent downward by the vertical load applied from the outside, the counter block 43 is moved away from the sealed case 41a and accordingly the sensor operation wire ( 41c) is pulled in the direction of the arrow d. As a result, the anchor block 41b pressurizes the piezoelectric element 41e, and the piezoelectric element 41e outputs an electric signal and sends it to the transmission module 41f. The transmission module 41f transmits the signal received from the piezoelectric element 41e to the control unit 45, thereby informing that the first and second bar members 32a and 32d have bent.

The controller 45 is located at the side of the support 31 where the drive 47 is located and controls the operation of the drive 47. It is a matter of course that the communication unit for wireless connection with the transmission module 41f is built in the control unit 45. The control part 45 operates the drive part 47 at the time of receiving a signal from the transmission module 41f, and causes the drive part 47 to tension the lifting wire 35 in the arrow a direction.

The drive part 47 tensions the lifting wire 35 and induces the force in the direction of the arrow z to cancel the vertical load on the crosspiece 32.

6 is a view for explaining the internal configuration and operation of the drive unit 47 of FIG.

As shown, the drive part 47 includes a winding roll 47f, a housing 47a, a motor 47b, a power supply 47d, a switch part 47c, and a transmission / reception module 47e.

The winding roll 47f is rotatably installed in the support post 31, and serves to wind or unwind the end of the lifting wire 35. When the winding roll 47f is wound around the lifting wire 35, the lifting wire 35 is pulled into the strut 31 and tensioned.

The housing 47a is a sealed box fixed to one side of the strut 31, and accommodates and protects the motor 47b, the power source 47d, the switch unit 47c, and the transmission / reception module 47e.

The motor 47b serves to rotate the take-up roll 47f by receiving electric power from the power source 47d. Operation of the motor 47b is controlled by the controller 45.

The power source 47d may be a rechargeable battery. Without using a battery as a power source, the power line can be pulled out for a long time and can be used with 220v power. At this time, an electrical element such as a converter is added to the housing.

The switch portion 47c is provided between the power source 47d and the motor 47b and is connected or shorted by receiving a control signal from the controller 45. Naturally, the operation of the motor 47b is made when the switch portion 47c is connected.

The transmission / reception module 47e is an element connected to the control unit 45. The control signal of the controller 45 is once transmitted to the driver 47 through the transmission and reception module 47e. In addition, the relevant information of the driving unit 47 is also sent to the control unit 45 through the transmission and reception module 47e.

As a result, as described above, the tent structure 30 of the present embodiment is configured, when the phenomenon that the crosspiece 32 sags downward due to the vertical load, the deflection detecting unit 40 detects the fact that the controller And the control unit 45 operates the drive unit 47 to output the force in the opposite direction to the deflection direction through the lifting wire 35, thereby preventing the deflection phenomenon.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
