Description

  The present invention relates to a sandbag aid that enables filling of sand and the like without the help of others when making a sandbag.

  There are various uses for sandbags. Regardless of making sandbags for disaster countermeasures or making sandbags on a small scale at home, etc. Needs to be spread out and held up. Normally, when making a sandbag, it is necessary to hold the bag in an open state by another person, which makes the filling operation troublesome. Therefore, some proposals have been made to enable the filling operation alone. As one of them, there has been proposed a large sandbag stuffing aid in which a plurality of support pillars are set up around the bottom plate, a traction member is attached to the upper end of each support pillar, and a clamp member is provided at the tip of these traction members. This auxiliary tool is placed in a frame with the opening of the sandbag bag facing upward, and the upper end of the sandbag bag is held by a clamp member to maintain the open state (Patent Document 1).

  As the second method, there is one in which an intersection located at the center in the length direction of a pair of leg portions formed by connecting members in a rectangular shape is rotatably supported by a support pin. Thereby, the sandbag apparatus assembled in the portable chair shape which can open and close an upper end part and a lower end part is proposed. This instrument is put in a sandbag bag in a closed state, and the upper and lower ends are opened so that the opening of the sandbag bag can be held open (Patent Document 2). As a third example, there is a sandbag device which is a cone-shaped or cylindrical tube and is provided with an earth and sand entrance with a wide opening at the upper end and a handle portion around it for easy use. It is possible to perform the filling operation in such a state that the sandbag wraps the sandbag or puts the sandbag in the sandbag (Patent Document 3). As a fourth example, there is a sandbag filling aid provided with a handle at the upper end of a cylindrical frame body formed in a tapered shape and a scale provided at a position visible from the opening at the upper end (Patent Document 4). ).

  Part 1 of the above-mentioned prior art is an auxiliary tool for making large sandbags, so it is not suitable for making sandbags on a small scale such as at home, and the structure is complicated, so the price is high. There are concerns. No. 2 has no problem in size, but there is a problem in work efficiency because it requires an opening / closing operation or an operation for holding it in an open leg state when taking it into and out of the sandbag. Since No. 3 is made of a cylindrical body, there is a concern that the resistance when pulling out the sand after filling it will increase, and in some cases the sand and sand may be taken out of the bag. The fourth is that the tapered cylindrical body is placed in the bag with the large-diameter portion facing down, so there is no concern about taking out the entire earth and sand when pulling out, but there is resistance between the frame and the bag when pulling out. Since it becomes large, there is a problem that the work of taking out the auxiliary tool becomes troublesome. An object of the present invention is to make it possible to provide a sandbag auxiliary tool that can be easily put in and out of the sandbag bag at a low cost.

  In order to solve the above-described problems, the sandbag auxiliary tool of the present invention (hereinafter, abbreviated as “auxiliary tool” where appropriate) has the following effects by employing the following means. The invention described in claim 1 is an annular body having a size corresponding to the size of the opening of the sandbag, a plurality of lengths, and extending downward from the annular body. It is characterized by having a holding member. The auxiliary tool can be put in a sandbag (hereinafter abbreviated as “bag” where appropriate), and the bag can be maintained in an open state to be filled with earth and sand. Since the resistance is small, the resistance is reduced and it can be easily pulled out.

  The invention described in claim 2 includes an annular body having a size corresponding to the size of the opening of the sandbag, and a plurality of holding members having a predetermined length and detachably provided on the annular body. Become. In this auxiliary tool, each holding member is removably attached to an attachment hole provided in the annular body so as to extend in a direction substantially orthogonal to the annular body. Since each holding member can be attached to and detached from the annular body, it is convenient for storage and transportation.

  According to a third aspect of the present invention, as a means for facilitating the assembly and disassembly of the auxiliary tool according to the second aspect, the annular body and the holding members include an annular body and the holding members. There is a feature in that attachment / detachment restricting means is provided which can prevent relative movement with respect to the annular body and attach / detach each holding member to / from the annular body. By adopting this attachment / detachment restricting means, a usable state in which each holding member is fixed to the annular body is obtained, and when not in use, it can be easily removed and disassembled for convenient storage and storage.

  The invention described in claim 4 is a modification of claims 1 to 3. That is, the annular body is made of an elastic body, and is cut out only in a predetermined section in the circumferential direction. This is because when the assisting tool is set in the bag, the annular body is deformed to a small diameter and then unloaded after being inserted into the bag, the annular body is elastically restored to its original state and the opening of the bag is expanded. The state can be maintained. The fact that there is no need to tie the opening of the bag with a mouth strap at the time of filling operation has the advantage that the opening state of the bag can be maintained without performing the operation of folding the upper end of the bag inside the annular body.

  According to the present invention, when making a sandbag, the opening portion of the sandbag bag can be held in an open state without the assistance of another person, so that filling work such as sand and sand can be performed. In addition, since the amount of the material used is small, the weight is reduced and the shape of the holding member is small, so that it is easy to pull out from the bag after filling, and the work for making the sandbag becomes easy.

  The sandbag assisting device according to the present invention is composed of a combination of an annular body and a plurality of holding members. However, there are some basic forms and modifications thereof, and these will be sequentially described below as examples. .

  As shown in FIG. 1, a sandbag auxiliary tool 1 as Example 1 has an outer peripheral portion having a dimension corresponding to an opening of a sandbag bag S, and an annular body 3 having a vertically long cross section. The holding members 5 are integrally provided. The annular body 3 and each holding member 5 employ hard synthetic resin molded products, and the thickness and width of the annular body 3 maintain the bag S in an open state and hold the four holding members 5. It is a dimension having the necessary strength. The holding member 5 has an appropriate thickness and width that are smaller than the thickness of the annular body 3, and the length is adjusted to be a guide for filling an appropriate amount of earth and sand in the bag.

  In the usage of this auxiliary tool, the auxiliary tool 1 is inserted into the bag S with the leading end of each holding member 5 first, and the opening of the bag is pulled up above the annular body 3. Next, the upper end portion of the bag is extended to above the annular body 3, and the upper end portion is folded inside the annular body 3 so that the bag does not slide down. The bag S maintained in the open state with the auxiliary tool 1 set in such a state is placed at a filling work position for earth and sand, etc., and earth and sand are filled from the opening with a scoop or the like. The amount of filling is preferably adjusted so that the volume of the sandbag thus obtained becomes a guide according to the length of the holding member 5 by setting earth and sand to be 1 cm or more below the lower part of the annular body 3. When a predetermined amount of earth and sand is filled, the top end of the bag is removed from the annular body 3 and the annular body is pulled out, so that only the filled earth and sand remain in the bag S. Finally, the opening of the bag S is closed, and a sandbag is completed by tying the mouth strap. When the auxiliary tool 1 is extracted, if the holding member is made relatively thin and the width is made narrow, it can be extracted with a small force. If the holding member 5 is provided with an inclination on both sides so that the width of the lower end portion is reduced, the extraction work is further facilitated.

  The auxiliary tool 11 according to the second embodiment has an annular body and a holding member as separate bodies, which are convenient for shipping and storage. As shown in FIGS. 2 and 3, the auxiliary tool 11 is configured such that four holding members 15,... Are detachably attached to an annular body 13 having a rectangular cross section having a predetermined thickness (t) and a width (b). Consists of things. A hole portion 13a, which is approximately half the thickness and an appropriate length is provided vertically at an intermediate position of the thickness (t) of the annular body 13, and a flange portion 15a having a flange-like upper end portion in the hole portion. The holding member 15 provided with is inserted. Each holding member 15 has substantially the same form as the auxiliary tool 1 of the first embodiment by being inserted until the lower surface of the flange portion 15a contacts the upper surface of the annular body 13.

  Each holding member 15 includes an attachment / detachment restricting means 17 so that the annular body 13 does not slide off the holding member 15. The following two examples are given as specific examples of the attachment / detachment restricting means 17. In the first example, as shown in FIG. 4, a notch 15b having a predetermined depth is provided in a range slightly larger than the width (b) of the annular body 13 from the lower surface of the flange 15a of the holding member 15. And one peripheral edge of the hole 13a. In the state where the holding member 15 is inserted into the hole 13a, the attachment / detachment regulating means 17 has a gap between the right side of the holding member 15 and the inside of the hole 13a as shown in FIG. Yes. In this state, since the annular body 13 and the holding member 15 are relatively movable, the annular body may slide down from a fixed position when it is set. Therefore, when the holding member 15 is shifted to the right from this state, as shown in FIG. 4 (A2), the notch 15b of the holding member 15 contacts the peripheral edge of the right end of the hole 13a, so that the annular body 13 is notched. It is locked to the lower part of the part 15b and does not slide down. Of course, the flange portion 15a needs to be dimensioned so as not to fall into the hole portion 13a even if the holding member 15 is displaced. At the time of disassembly, the attachment / detachment restricting means 17 can be relatively moved only by shifting the annular body 13 and the holding member 15 in the opposite directions. In order to prevent the locking relationship from being released due to vibration or the like during use, it is desirable that the dimension of the hole 13a and the dimension of the holding member have high processing accuracy so as not to cause backlash. . The method of using the assembled auxiliary tool 11 (see FIGS. 2 and 3) is the same as that of the auxiliary tool 1 of the first embodiment.

  As a modification of the second embodiment, the auxiliary tool 21 of the third embodiment uses three holding members and another configuration as a second example of a specific example of the attachment / detachment regulating means. When there are three holding members, there are advantages that the holding member can easily enter the bag and the stability when placed on the ground is improved. The annular body 23 is provided with three hole portions 23a for the attachment / detachment restricting means 27 at equal intervals, and an apron having an inner side at a position in contact with the outer side of each hole portion on the lower surface of the annular body 23. An engaging piece 23b is suspended. The width of the engaging piece 23 b is wider than the width of the leg portion 25 b of the holding member 25, and the length is about one third of the length of the holding member 25. In the vicinity of the lower end portion of the engagement piece 23b, a protrusion 23c constituting the attachment / detachment restricting means 27 is provided. The upper part of the projection 23c is rounded or chamfered to facilitate the work when the holding member 25 is inserted into the annular body 23. As in the holding member 15 of the second embodiment, the holding member 25 is formed by extending the leg portion 25b from the lower surface of the flange portion 25a. In this embodiment, the leg portion 25b is formed straight. In a state where the holding member 25 is inserted into the hole portion 23a of the annular body 23 until the flange portion 25a comes into contact with the upper surface of the annular body 23, a position 25c is provided at a position corresponding to the protruding portion 23c. In addition, a protrusion part may be provided in the leg part 25b of the holding member 25, and the hole for engagement may be provided in the engagement piece 23b.

  The attaching / detaching restricting means 27 inserts the leg portion 25 b of the holding member 25 into the hole portion 23 a of the annular body 23 and pushes it until the flange portion 25 a contacts the upper surface of the annular body 23 during use. At this time, the protrusion 23c presses the outer surface of the holding member 25. However, since the protrusion is chamfered, resistance when the holding member 25 is pushed in is reduced. When disassembling the auxiliary tool 21, the engagement piece 23b is shifted outward, or the lower portion of the holding member 25 is deformed inward, for example, so that the engagement hole 23c and the projection 23c are engaged. It can be easily extracted by canceling the connection.

  The auxiliary tool 31 of the fourth embodiment is a modification of the first to third embodiments, in which an annular body can be elastically deformed. As shown in FIG. 7, the auxiliary tool 31 of the fourth embodiment is composed of an annular body 33 and four holding members 35, as in the auxiliary tool 1 of the first embodiment. This is configured by providing a notch 33a that is notched and removed by a predetermined length in the direction. As shown in FIG. 8, the annular body 33 is easy to set in the bag by utilizing the fact that the outer peripheral portion becomes smaller due to elastic deformation when a force is applied in the direction of the arrow. Therefore, if the size of the annular body 33 in the natural state is slightly larger than the size of the opening of the bag, the inner peripheral portion of the bag is elastically held by the outer peripheral portion of the annular body 33. The bag does not slide off from the auxiliary tool 31 even if the tip portion is not folded back or tied with a mouth strap.

  Regarding the dimensions of the annular body 33, it is necessary to adjust the thickness (t) and the width (b) in order to facilitate elastic deformation. Further, it is desirable that the material has a property suitable for elastic deformation. In the fourth embodiment, it is an integrated type, but this annular body may be an assembly type as in the second or third embodiment. In this case, if there is a design restriction such as strength for reducing the thickness (t) of the annular body, the thickness may be increased only in the range where the hole is provided.

  In the above description, the number of holding members is three or four. However, in any embodiment, this number is not limited, and may be appropriately determined in consideration of the size and other conditions. Moreover, although the synthetic resin molded product is employ | adopted as a raw material, a raw material is not restricted to this, Metals, such as aluminum, and a timber processed product may be sufficient. The shape of the annular body is not limited to a circle, and may be an ellipse or a polygon. The cross-sectional shape is not limited to a rectangular cross section, and may be an ellipse or other shapes. Furthermore, the main use of this auxiliary tool is as an auxiliary tool for making sandbags, but it may also be used as a shaving collection bag in a woodworking place. With this auxiliary tool, the bag is opened in the work place, and it is put into the bag whenever wood chips or the like are generated, and is tied with a mouth strap when a predetermined amount is reached. In addition, this auxiliary tool is convenient when used as a sludge storage bag when cleaning side grooves or the like. That is, it is convenient to prepare an item opened using this auxiliary tool, and to put the removed sludge or the like into this as appropriate without any help.

  The present invention facilitates making sandbags, but has sufficient industrial applicability because it is supplied through industrial production.
