Description

The present invention relates to a seat connector that uses a general-purpose sheet (blue sheet) eyelet to connect sheets downward (directly below, obliquely affected by gravity).

In recent years, sheets made of synthetic resin (blue sheets) are commercially available as general-purpose products, and are used not only at construction sites and disaster sites, but also at ordinary households. When using, if the range to be covered is wide and large, one sheet is insufficient, and it is necessary to connect a plurality of sheets. Usually, eyelets on the periphery of the sheet are tied with a rope or the like, but since it takes time, various connecting tools related to the following sheet connection have been proposed. For example, as shown in Patent Document 1 (surface fastener) and Patent Document 2 (metal fitting), a connecting member (surface fastener, metal fitting) is integrally attached to the sheet base, and the sheet itself is special. Moreover, there exists a connection material which makes easy the knot operation | movement with the eyelet of the sheet | seat to connect shown in patent document 3. FIG. Moreover, there exists a connection tool which has both ends of the shape shown to patent document 4 and engages with each eyelet of the sheet | seat to be connected. And the connection tool etc. of patent documents 3 and 4 are connected in the state where the end of a sheet is faced. Furthermore, the connector shown in Patent Document 5 is connected by sandwiching both ends of the sheet with a pair of long plates.

It is a front view of the partial cross section of the sheet | seat coupling tool of 2nd Embodiment which concerns on Claim 4.

Below, 1st Embodiment of the seat coupling tool 1 corresponding to Claim 2 subordinate to Claim 1 is described with reference to drawings. The sheet connector 1 according to the first embodiment shown in FIG. 1 includes a main body 2, a first arm 3, a second arm 4, and a weight portion 5, and is integrally manufactured by zinc casting. Thus, it has a simple shape, is not too heavy compared to cast iron, etc., and is easy to transport and handle.

As shown in FIG. 1, the main body 2 is a rod-shaped body having a substantially circular cross section. A first arm 3 and a second arm 4 are provided along the main body axis 6, and a weight portion 5 is provided at one end. Provided. The diameter of the transverse section is sufficient to connect the sheets, and in this first embodiment, the diameter is 8 mm.

As shown in FIG. 1, the first arm 3 has a first arm base portion 7 a, a first arm tip portion 8 a, and a first retaining projection 9 a from the main body 2 side, and a first gap 10 a between the first arm 3 and the main body 2. Is forming. The first arm portion 7 a has a substantially circular cross section and is connected to the outside with a substantially right angle as the angle with respect to the main body axis 6. The first arm tip 8a has a substantially circular cross section, is parallel to the body axis 6, extends from the first arm 7a in the direction of the weight 5 and has a rounded tip. ing. The size of the cross section of the first arm portion 7a and the first arm tip portion 8a is such that it can be easily inserted into the eyelet 21 of the upper sheet 20, and there is not enough room in the eyelet even after insertion. Thus, it is a size that does not easily fall out. In the first embodiment, the diameter is 8 mm. The first gap 10a is a space surrounded by the main body 2, the first arm portion 7a, and the first arm tip portion 8a, and secures a volume that can accommodate three eyelets 21 of the upper sheet 20 in a stack. In the gravity-coupled sheet connector 1, when the weight portion 5 is the lowermost end and the first arm 3 is inserted into the eyelet 21 of the upper sheet 20, the first arm base portion 7 a is caught by the eyelet 21, The sheet 20 can be stored in the space of the gap 10a. Accordingly, if the first gap 10a is too narrow, it will be an obstacle to insertion and hooking into the eyelet 21, and if it is too wide, it will be easy to come off, so it is necessary to secure an appropriate volume as described above. The first retaining protrusion 9a has a substantially rectangular cross section and is formed on the first gap 10a side of the first arm tip 8a. The height of the first retaining protrusion 10 a is a height corresponding to the end thickness of the upper sheet 20. Further, the length of the first retaining protrusion 10a is a length that secures a space in the longitudinal direction of the first arm tip 8a so that the end of the upper sheet 20 can be stored in the first gap 10a. As a result, when the first arm portion 7a is hooked on the eyelet 21 of the upper sheet 20, the upper sheet 20 is guided by the first arm tip portion 8a and is prevented from being detached by the first retaining projection 9a, so that it enters the first gap 10a. Stored. In addition, the front-end | tip of the 1st extraction protrusion 9a is formed in the curved surface, and the insertion / extraction to the eyelet 21 of the 1st arm 3 is made smooth with the roundness of the front-end | tip of the 1st arm tip part 8a.

As shown in FIG. 1, the second arm 4 has a second arm base portion 7 b, a second arm tip portion 8 b, and a second retaining projection 9 b from the main body 2 side, and a second gap 10 b between the second arm 4 and the main body 2. Is forming. The second arm portion 7b and the second arm tip portion 8b have a substantially circular cross section, and have the same diameter as the first arm tip portion 7a and the first arm tip portion 8a, so that they can be easily inserted and hooked into the eyelet. To prevent damage and falling off. The second arm portion 7b is connected to the outer side opposite to the first arm portion 7a with the main body axis 6 as the center, and is connected at a substantially right angle similarly to the first arm portion 7a. When the upper and lower sheets 20 and 30 are hung on each of the first and second arm portions 7a and 7b at a position relative to the first arm portion 7a, the lower end side of the upper sheet 20 is always aligned with the lower sheet 30. The overlapped portion width W (see FIG. 1) of the upper and lower sheets 20 and 30 is generated below the upper end side of the sheet. Like the first arm tip portion 8a, the second arm tip portion 8b is parallel to the main body axis 6 and has a rounded tip, but the second arm tip portion is directed in the opposite direction to the weight portion 5 direction. The point which extends from 7b is different. Accordingly, the second gap 10b in the space surrounded by the main body 2, the second arm portion 7b, and the second arm tip portion 8b is formed at a position in the opposite direction of the weight portion 5 with respect to the first gap 10a. A volume capable of storing 30 eyelets 31 in a stack of three is secured. The reason for this is that in the gravity-operated sheet connector 1, when the second arm 4 faces upward and the eyelet 31 of the lower sheet 30 is hooked on the second arm tip 8 b, the lower sheet 30 enters the space of the second gap 10 b. This is because it is necessary to secure an appropriate volume as in the first gap 10a. The second retaining protrusion 9b has a substantially rectangular cross section, and has a tip with a curved surface on the second gap 9b side of the second arm tip 8b. The height of the second retaining protrusion 9 b is a height corresponding to the end thickness of the lower sheet 30. Moreover, the length is a length which ensures the space which can accommodate the edge part of the lower sheet | seat 30 in the 2nd clearance gap 10b in the longitudinal direction of the 2nd arm tip part 8b. The lower sheet 30 accommodated in the second gap 10b is guided by the second arm tip portion 8b and is prevented from coming off by the second retaining protrusion 9b. Similarly to the first retaining protrusion 9a, the eyelet 31 can be easily and smoothly attached to the second arm 4 by the curved surface at the distal end of the second retaining protrusion 9b and the roundness at the distal end of the second arm tip 8b. ing.

As shown in FIG. 1, the weight portion 5 is a substantially spherical body that is provided at one end of the main body 2 and has a center of gravity on the main body axis 6, and is positioned at the lowermost end of the seat connector 1 in a gravity action state. Have weight. In the first embodiment, the weight that causes the center of gravity to be generated in the weight portion 5 is appropriately secured in the weight portion 5 in the total weight 150 to 250 grams of the seat connector 1. Further, as shown in FIG. 2, the weight portion 5 passes through the spherical center 5 a of the weight portion 5 and is formed by the main body axis 6, the first arm 3, the second arm 4, and the main body axis 6. A through-hole 11 having a line perpendicular to the center line 11a is provided. Both ends of the through hole 11 are chamfered to form a flat receiving surface 12. A member such as a rope or a rod, which connects a plurality of sheet couplers 1 hung on the sheet eyelet, can be inserted into the through hole 11, and the rope or the like is parallel to the sheet surface. For this reason, the diameter of the through hole 11 is processed according to the thickness of a rope or the like, and the receiving surface 12 is used for installation of a rope knot or a rod fixing nut.

Next, with reference to FIG. 3, the operation | movement which connects the upper and lower sheet | seats 20 and 30 of a commercial item to the downward direction which gravity influences using the sheet | seat coupling tool 1 of 1st Embodiment is demonstrated. First, as shown in FIG. 3 (a), the sheet connector 1 is also suitable for transport and handling, and the first arm 3 of the sheet connector 1 with the weight portion 5 at the lowermost end is connected to the eyelet of the upper sheet 20. It can be easily put into a mounted state by being inserted and hooked on 21. The weight of the sheet connector 1 acts downward on the upper sheet 20 in the mounted state by the insertion and hooking operations, and the upper sheet 20 is stably stretched. Next, as shown in FIG. 3B, the eyelet 31 of the lower sheet 30 is hooked on the second arm 4 on the back side of the upper sheet 20. In this way, the connecting operation between the upper and lower sheets 20 and 30 and the sheet connector 1 can be performed easily and easily. In addition, the first and second retaining protrusions 9a and 9b and the first and second gaps 10a and 10b ensure that the seat eyelet and the seat connector 1 are securely engaged, and the sheet connector 1 can be prevented from falling off. It becomes. 3C, the upper sheet 20 and the lower sheet 30 are connected by the sheet connector 1, and the downward force due to the weight of the lower sheet 30 is increased via the sheet connector 1. It is transmitted to the sheet 20 and the upper sheet 20 does not loosen. Further, the overlapping width W of the upper sheet 20 and the lower sheet 30 is also generated, and the lower end side 22 of the upper sheet 20 is positioned below and on the outer side with respect to the upper end side 32 of the lower sheet 30, so Waterproofing against rain can be achieved without entering the back side of 30.

4 is a case where the upper sheet 20 covering the roof and the lower sheet 30 covering the wall are coupled in the direction of gravity action, and a plurality (seven in the figure) of the sheet coupling tool. 1 is used. Although illustration is omitted, it is possible to connect a plurality of sheet couplers 1 through ropes to the through holes and stabilize them so as to prevent them from falling off, or to prevent the sheet from being undulated by being blown by wind or the like. As another use example, it is also used for sheet connection when covering a slope such as a roof, a cliff, or a slope.

If the lower sheet 30 is not connected, the illustration is omitted, but the first arm 3 is hung on the eyelet at the lower end of the sheet, and the rope is pulled down through the through hole 11 to fix the rope to the ground pile or a fixed object. You can also use it. Furthermore, as an urgent use example, in the worst weather situation such as heavy rain or storm, the first arm 3 and the second arm 4 are bent to the main body side with a tool such as a pliers to make the sheet eyelet. It can be firmly fixed to increase the connection strength. This is possible because metal casting uses relatively soft zinc.

Next, another embodiment of the seat connector corresponding to claim 1 will be described. One embodiment is a case where the material used is not limited to metal but a synthetic resin material with guaranteed mechanical strength is also employed, and is suitable when weight reduction is important. Moreover, even if it is a metal, the sheet | seat coupling tool 1 can also be manufactured by press work, without being limited to casting, and it is excellent in mass-productivity. Further, in the case of the above-described synthetic resin material and press working, only the weight portion 5 is divided from the sheet connector 1 and the weight portion 5 is used as a cast product. Then, a weight necessary for the weight part 5 is ensured by connecting or detaching the body 2 and the weight part 5 such as a synthetic resin material other than the weight part. In addition, the weight part 5 should just be a solid | solid body which has a gravity center on the main-body axis 6, and can employ | adopt polyhedrons, such as a cube, without being limited to the substantially spherical body of 1st Embodiment.

In another embodiment, the angle when the first and second arm portions 7a and 7b are connected to the main body 2 is not limited to a substantially right angle with respect to the main body axis 6 of the main body 2. An angle smaller than a right angle is adopted as an angle generated on the second gap side 10a, b. The first and second gaps 10a and 10b are narrowed, and the engagement state (hanging state) between the first and second arms 3 and 4 of the seat connector 1 and the eyelets 21 and 31 can be strengthened.

In the last one embodiment, the relative position of the second arm portion 7b with respect to the first arm portion 7a in the direction of the body axis 6 is not limited to the substantially equivalent position of the first embodiment, and is opposite to the weight portion 5. It is the structure which becomes the position of a direction. If it is this structure, the lower end side of the upper sheet | seat 20 will always be located under the upper end side of the lower sheet | seat 30, and the overlapping part width W (refer FIG. 1) of the upper and lower sheets | sheets 20 and 30 is ensured suitably, and is waterproof. Can improve the performance.

Next, the sheet connector corresponding to claim 3 has a configuration in which an elastic material tube (for example, a rubber tube) is disposed at the distal end portion of the first arm 3 and the second arm 4 although illustration is omitted. is there. The elastic material tube stabilizes the sheets 20 and 30 in the first and second gaps 10a and 10b, thereby preventing the sheet connector 1 from coming off from the eyelets 21 and 31.

In the second embodiment of the seat connector 41 corresponding to claim 4, as shown in FIG. 5, the first and second arm base portions 44 a and 44 b of the first arm 42 and the second arm 43 are located with respect to the main body 2. It is configured to be detachable. That is, a plurality of arm mounting holes 45 are provided in the direction of the main body axis 6 of the main body 2, and on the other hand, first ends of the first and second arm base portions 44 a and b are detachably engaged with the arm mounting holes 45. First and second mounting protrusions 46a and 46b are provided, respectively. Therefore, the first arm 42 and the second arm 43 can be attached to and detached from the main body 2 at arbitrary positions. The overlapping width W of the upper and lower sheets 20 and 30 can be varied by the first arm 42 being always located in the same direction as the second arm 43 in the direction of the main body axis 6 or on the weight part 5 direction side. Yes (see FIG. 1).

While several embodiments of the present invention have been described, these embodiments are illustrative and are not intended to limit the technical scope of a registered utility model. These novel embodiments can be implemented in various other forms, and can be omitted, replaced, or changed without departing from the gist of the registered utility model.
