Description

The present invention relates to a frame structure for a tent.

Conventionally, when installing a tent outdoors, the frame structure is first installed at the installation location of the tent. Various types of this frame structure are known, but the basic structure is the same. For example, in Patent Document 1, the frame structure is a column member mounted on an installation surface for installing a tent, and the column member. And a beam member spanned so as to form a gate shape having a space therebetween. Then, a tent membrane is stretched so as to cover the outside of the frame structure, and the tent is used.

Further, by redesigning the shape of the frame structure according to the size of the tent, particularly the size of the front of the tent, tents of various uses and sizes can be manufactured. However, if the shape of the frame structure is redesigned every time the frontage of the tent changes, there is a problem that it takes time and cost.

Patent No. 6053898

Therefore, the present invention provides a frame structure that can easily cope with a change in the frontage of the tent and that can reduce the cost.

In order to solve the above-mentioned problems, the frame structure of the present invention is a gate having a support member mounted so as to face the installation surface on which the tent is installed, and a space between the support members on opposite sides. A beam member hung between the pillar members so as to form a shape, the beam member being a pillar-side beam member detachably connected to the pillar members on both sides, and the pillar-side beam. A variable beam member that is detachably connected to the member, and an intermediate beam member that detachably connects the variable beam members on both sides, and the variable beam member has an overall length depending on the size of the frontage of the tent. It is characterized in that it is configured to be replaceable with another different variable beam member.

According to the above feature, when it is desired to change the frontage of the tent, it is possible to easily cope with it by replacing only the variable beam member with a variable beam member having a different total length. Furthermore, by only exchanging the variable beam member, it is not necessary to change the components other than the variable beam member (the strut member, the strut side beam member, the intermediate beam member), and they can be used as they are, so that the cost can be suppressed.

Further, the frame structure of the present invention is characterized in that the strut-side beam member and the intermediate beam member can be detachably directly connected without the interposition of the variable beam member.

According to the above feature, since the variable beam member can be removed and the column-side beam member and the intermediate beam member can be directly connected and fixed, it is possible to easily cope with the case where the frontage of the tent is further narrowed.

Further, in the frame structure of the present invention, the connection between the variable beam member and the intermediate beam member is performed by associating the end portion of the variable beam member and the end portion of the intermediate beam member with each other. It is characterized in that it is formed by arranging the connecting plate from the outside so as to straddle it and fixing the respective end portions and the connecting plate.

According to the above feature, the connection between the variable beam member and the intermediate beam member becomes very easy, and in particular, because the method is to fix the connecting plate from the outside so as to straddle both ends, the removal of the variable beam member and the Easy to install.

Further, in the frame structure of the present invention, the connection between the variable beam member and the strut-side beam member is such that the end portion of the variable beam member and the end portion of the strut-side beam member are brought into contact with each other. It is characterized in that it is formed by arranging the connecting plate from the outside so as to straddle the parts and fixing the respective end portions and the connecting plate.

According to the above feature, the connection between the column-side beam member and the variable beam member becomes very easy, and in particular, the method of fixing the connecting plate from the outside so as to straddle both ends, removes the variable beam member. And the mounting becomes easy.

Further, in the frame structure of the present invention, when the tent film is stretched so as to cover the outside of the frame structure, the curvature of the contact portion of the pillar-side beam member with which the tent film contacts and the tent. The curvature of the abutting portion of the intermediate beam member with which the film abuts is equal.

According to the above feature, when the tent membrane is stretched outside the frame structure, the tensile force of the tent membrane contacting each contact portion becomes substantially uniform, so that the tensile force applied to the entire tent membrane is uniformly dispersed. As a result, the durability of the tent membrane is increased.

The frame structure of the present invention can easily cope with a change in the frontage of the tent and can reduce the cost.

Then, the connecting plate 800 is applied from the outside to the front surface and the back surface of the continuous connecting surface 640 and the connecting surface 730, respectively. The connecting plate 800 is provided with a plurality of through holes 801, and each through hole 801 overlaps each through hole 641 of the connecting surface 640 and each through hole 731 of the connecting surface 730. Then, the bolt 802 is attached so that the through hole 801 and the through hole 641 of the connecting plate 800 on one side (the upper side in the drawing) and the through hole 801 of the connecting plate 800 on the other side (the lower side in the drawing) are inserted. The tip of 802 is fixed with a nut 803.

The beam members 700 are firmly connected and fixed to each other by the connecting plate 800.

Similarly, as shown in FIG. 4A, the variable beam member 600 and the strut-side beam member 500 are placed in a state of lying on a horizontal plane, and the end portion of the base end 610 of the variable beam member 600 and the strut-side beam member 500 are placed. Butt with the end of the tip 520. Then, the connecting surface 540 of the strut-side beam member 500 and the connecting surface 630 of the variable beam member 600 become a continuous flat surface. Then, the connecting plate 800 is applied from the outside to the front surface and the back surface of the continuous connecting surface 630 and the connecting surface 540, respectively. The connecting plate 800 is provided with a plurality of through holes 801, and each through hole 801 overlaps each through hole 631 of the connecting surface 630 and each through hole 541 of the connecting surface 540. Then, a bolt 802 is attached so that the through hole 801 and the through hole 631 of the one connecting plate 800 and the through hole 801 of the other connecting plate 800 are inserted, and the tip of the bolt 802 is fixed with a nut 803. Similarly, a bolt 802 is attached so that the through hole 801 and the through hole 541 of the one connecting plate 800 and the through hole 801 of the other connecting plate 800 are inserted, and the tip of the bolt 802 is fixed with a nut 803. Then, the connecting plate 800 which is addressed so as to straddle the end of the base end 610 of the variable beam member 600 and the end of the tip 520 of the strut-side beam member 500 is fixed to each end, and as a result, the variable beam The member 600 and the pillar-side beam member 500 are firmly connected and fixed to each other by the connecting plate 800.

As described above, as shown in FIG. 4B, the variable beam member 600 is connected and fixed between the support beam member 500 and the intermediate beam member 700 by the connecting plate 800. The connecting and fixing between the connecting surface 740 of the intermediate beam member 700 and the tip 520 of the column-side beam member 500 is also performed by the same method as described in FIG. 4A.

Further, the connection and fixation between the tip end 320 of the strut member 300 and the base end 510 of the strut-side beam member 500 is also performed by the same method as described in FIG. 4A. Although not shown, specifically, the end of the tip 320 of the strut member 300 and the end of the base end 510 of the strut-side beam member 500 are brought into contact with each other to form a continuous connecting surface 330 and a surface of the connecting surface 530. The connecting plate 800 is applied from the outside to each of the back surfaces, and the connecting plate 800 is fixed to each end by bolts 802 and nuts 803. Then, the pillar member 300 and the pillar-side beam member 500 are firmly connected and fixed to each other by the connecting plate 800. Then, the pillar member 300, the pillar-side beam member 500, the variable beam member 600, and the intermediate beam member 700 are connected and fixed to each other by the connecting plate 800, whereby the portal-shaped frame structure 100 shown in FIG. 2 is assembled. Be done. When the tent T is no longer needed, the bolt 802 and the nut 803 are removed and the connection by the connecting plate 800 is released to remove the support member 300, the support-side beam member 500, the variable beam member 600, and the intermediate beam member 700. Disassemble and store. Further, by setting the total length of each of the column member 300, the column-side beam member 500, the variable beam member 600, and the intermediate beam member 700 to be within 5 m (meter), they can be easily stacked and transported on a truck or the like. Further, each of the column member 300, the column-side beam member 500, the variable beam member 600, and the intermediate beam member 700 is formed to have a thin thickness and a flat shape, as shown in FIG. 1B and FIG. 4B. Therefore, it is easy to stack when storing.

Although each member is connected using the connecting plate 800, the bolt 802, and the nut 803, the present invention is not limited to this, and other connecting and fixing methods may be used as long as each member can be detachably connected. May be. However, as shown in FIG. 2, when the connecting plate 800 is attached to the front and rear surfaces of each member so that the connecting plate 800 faces parallel to the front side when the frontage of the front side of the frame structure 100 is viewed, Each fixed part is further reinforced. Specifically, as shown in FIG. 1B, since the plurality of frame structures 100 are connected to each other so that the tent T extends in the depth direction (front-back direction), each member of the frame structure 100. A load in the depth direction is applied to the connecting portion of the tent T due to the tension of the tent T, an external force, or the like. Therefore, when the connecting plates 800 are attached to the front and rear surfaces of each member so as to face the front side of the frontage in parallel, the respective connected and fixed portions are further reinforced.

Here, the frame structure 100 shown in FIG. 2 is configured such that the frontage L1 is 12.5 m (meter). However, there are cases where it is desired to narrow the frontage depending on the specifications and customer demand. In that case, as shown in FIG. 5A, by removing the variable beam member 600 and directly connecting the intermediate beam member 700 and the strut-side beam member 500, the frontage can be narrowed. As a result, in the frame structure 100 shown in FIG. 5A, the frontage L2 is 10 m (meter). 5(a) and 5(b) are front views in a state in which the length of the frontage of the frame structure 100 of the present invention is changed.

As described above with reference to FIG. 4, the connecting and fixing of the variable beam member 600 and the strut-side beam member 500 and the connecting and fixing of the variable beam member 600 and the intermediate beam member 700 are common connecting plates. 800 is configured to be performed. Therefore, as shown in FIG. 5A, when the variable beam member 600 is removed and the intermediate beam member 700 and the strut-side beam member 500 are directly connected, the connecting plate 800 can be used as it is. Specifically, the variable beam member 600 is removed, and the end portion 520 of the column-side beam member 500 and the end portion 710 of the intermediate beam member 700 are attached to each other. Then, the connecting surface 730 of the intermediate beam member 700 and the connecting surface 540 of the strut-side beam member 500 become a continuous flat surface. Then, the connecting plate 800 is applied from the outside to the front surface and the back surface of the continuous connecting surface 540 and the connecting surface 730, respectively. Next, the connecting plate 800, which is arranged so as to straddle the end of the tip 520 of the strut-side beam member 500 and the end 710 of the intermediate beam member 700, is fixed to each end with bolts 802 and nuts 803. The column-side beam member 500 and the intermediate beam member 700 are firmly connected and fixed to each other by the connecting plate 800.

Furthermore, there are cases where it is desired to widen the frontage depending on the specifications and the demands of customers. In that case, as shown in FIG. 5B, the frontage L3 can be widened by replacing the variable beam member 600' with a long total length. In the frame structure 100 shown in FIG. 5B, the frontage L3 is 15 m (meter). The variable beam member 600 ′ is the same as the variable beam member 600 in other respects except that the total length L 4 is longer than the total length L 5 of the variable beam member 600. Therefore, when connecting the variable beam member 600 ′ between the support beam member 500 and the intermediate beam member 700 instead of the variable beam member 600, the connecting plate 800 described in FIG. 4A is used. The same method as the method of connecting and fixing the variable beam member 600 between the strut-side beam member 500 and the intermediate beam member 700 can be used.

Specifically, although not shown, the end portions 710 and 720 of the intermediate beam member 700 are respectively associated with the end portions of the tip ends of the variable beam members 600′, and the end portions are straddled. The connecting plate 800 is applied from the outside, and the connecting plate 800 is fixed to each end by bolts 802 and nuts 803. Then, the variable beam member 600' and the intermediate beam member 700 are firmly connected and fixed to each other by the connecting plate 800. In this way, the variable beam member 600 can be easily replaced with a variable beam member 600' having a different total length. Further, the components other than the variable beam member 600 (that is, the column member 300, the column beam member 500, the intermediate beam member 700, and the connecting plate 800) do not need to be changed, and can be used as they are even if the frontage is changed. The variable beam member 600 ′ has a longer overall length than the variable beam member 600, but is not limited to this. The variable beam member 600 ′ may have a shorter overall length than the variable beam member 600, and the variable beam member 600 ′ has an arbitrary length. You may say so. The total length of the variable beam member 600' may be freely set in units of several mm.

Thus, according to the frame structure 100 of the present invention, as shown in FIG. 5B, when it is desired to change the frontage of the tent T, only the variable beam member 600 is changed to a variable beam member 600′ having a different total length. By exchanging them, it is possible to deal with them easily. Further, only the variable beam member 600 is replaced, and the components other than the variable beam member 600 (the strut member 300, the strut side beam member 500, the intermediate beam member 700, the connecting plate 800) do not need to be changed and can be used as they are. it can. That is, in several types of tents T having different frontages, the constituent elements (the strut member 300, the strut side beam member 500, the intermediate beam member 700, the connecting plate 800) other than the variable beam member 600 are standardized common parts, Even if the size of the frontage is changed, the manufacturing cost of the frame structure 100 can be suppressed.

In addition, since each component (support member 300, support-side beam member 500, intermediate beam member 700, connecting plate 800) is a standardized common part, even if some of the components are deteriorated or damaged, the configuration is concerned. Only the elements need to be replaced, maintainability is good, and costs can be reduced. Further, when the frontage is changed according to the demands of a plurality of customers, it is possible to deal with it only by changing the variable beam member 600, and since each component can be repeatedly used, for example, for short-term rental or When renting the frame structure 100 of the present invention for a lease contract, the cost can be suppressed.

In the frame structure 100 of the present invention, from the viewpoint of optimizing the design of the frame structure 100, only the variable beam member 600 is replaceable with a variable beam member 600 ′ having a different total length. (Strut members 300, pillar-side beam members 500, intermediate beam members 700, connecting plates 800) are standardized common parts. Specifically, when the frontage of the tent T is changed, it is possible to change the total length of the column-side beam member 500 or the intermediate beam member 700. However, the strut-side beam member 500 is a part having high strength to support the weight of the beam member 400, and is also a part where many connecting members 200 are installed. In addition, in order to connect and fix the support member 300, the support member 300 has a substantially L-shaped complex shape. Therefore, when changing the entire length of the strut-side beam member 500, the strut-side beam member 500 has a complicated shape, the strength of the strut-side beam member 500 is secured, and the installation position of the connecting member 200 is changed. Various factors have to be taken into consideration, and redesign is very troublesome and costly. On the other hand, the intermediate beam member 700 is a portion that forms the top of the tent T and is a portion that connects the variable beam members 600 or the strut-side beam members 500 on both sides, so that a load is easily applied, and the intermediate beam member 700 has a substantially V shape. It has a complicated shape. Therefore, when changing the total length of the intermediate beam member 700, in addition to the intermediate beam member 700 having a complicated shape, various factors such as ensuring the strength of the intermediate beam member 700 must be taken into consideration. The design is very troublesome and costly. Therefore, in the frame structure 100 of the present invention, only the variable beam member 600 between the strut-side beam member 500 and the intermediate beam member 700 is changed in design, and the strut-side beam member 500 and the intermediate beam member 700 are standardized and common. It was a part. The variable beam member 600 is a component that connects the strut-side beam member 500 and the intermediate beam member 700, and the design change is easier than the strut-side beam member 500 and the intermediate beam member 700. Further, since the variable beam member 600 is a member having a simple shape that extends linearly, even if the total length is changed, complicated strength calculation and the like can be avoided and redesigning is easy.

Further, according to the frame structure 100 of the present invention, as shown in FIG. 5A, the variable beam member 600 is removed to support the case in which the frontage of the tent T is desired to be changed to be narrower. The intermediate beam member 500 and 500 are directly connected and fixed. Therefore, it is possible to easily assemble the tent T having a narrowed frontage by simply removing the variable beam member 600, and at the same time, constituting elements other than the variable beam member 600 (the strut member 300, the strut side beam member 500, the intermediate beam member 700). Since the connecting plate 800) does not need to be changed and can be used as it is, the manufacturing cost of the frame structure 100 can be suppressed.

Further, according to the frame structure 100 of the present invention, the connection between the strut-side beam member 500 and the variable beam member 600 is performed by associating the end portion of the strut-side beam member 500 with the end portion of the variable beam member 600. Since the connecting plate 800 is applied from the outside so as to straddle both ends, and each end is fixed to the connecting plate 800, the connection between the strut-side beam member 500 and the variable beam member 600 is very easy. It's easy. In particular, since the connecting plate 800 is fixed from the outside by straddling both ends, the variable beam member 600 can be easily removed and attached.

Further, according to the frame structure 100 of the present invention, the connection between the variable beam member 600 and the intermediate beam member 700 is performed by connecting the end portion of the variable beam member 600 and the end portion of the intermediate beam member 700 to each other. This is done by arranging the connecting plate 800 from the outside so as to straddle the ends and fixing each end and the connecting plate 800, so that the variable beam member 600 and the intermediate beam member 700 can be connected very easily. .. In particular, since the connecting plate 800 is fixed from the outside by straddling both ends, the variable beam member 600 can be easily removed and attached.
