JP 2001-48302 A Utility Model No. 3089718 JP 2006-76694 A.

  In Patent Document 1, a pair of rectangular panels are arranged opposite to each other so as to be relatively close to and away from each other by an X arm, and a large number of slits for inserting garbage bags are engraved at the upper end of each rectangular panel. A garbage bag support is described. In Patent Document 2, a handle trunk is set up on a cart with casters, and a U-shaped frame supporting the opening edge of the garbage bag is attached thereto, and the opening edge of the garbage bag is attached with a clip suspended from the frame body. Various types of handbag-type garbage bag trolleys are described. In Patent Document 3, a π-type (torii-type) first leg is set up on one side of a rectangular frame base, and a similar second leg is set up facing the opposite side and supported by the rectangular frame base in a tiltable manner. Then, a ring at the end of a pair of hooked rods for holding the garbage bag opening in a quadrangular shape at the upper end of the first leg is suspended and supported, and the hook at the tip is engaged with the upper end of the second leg. A trash bag support stand is provided, which forms a rectangular trash bag support mold with the upper ends of the first and second legs, and fixes the opening edge of the trash bag to a stick with a hook with a clothespin. ing.

  When putting garbage into the supported garbage bag, the opening may be widened by hand, and the object to be put may hit the opening edge and force may be applied to the opening edge. In any of Patent Documents 1 to 3, in such a case, it is considered that the opening edge of the bag is detached from the support portion of the stand or torn. On the other hand, when separately collecting garbage, it is preferable to support a plurality of garbage bags side by side with openings. Also, when storing lots of garbage one after another at gardens, roads, parks, construction sites, construction sites, or building demolition sites, it is easy to replace bags by holding many garbage bags one after another. It is preferable to carry out quickly.

  The first object of the present invention is to flexibly support the opening edge of a bag, and the second object is to allow a plurality of bags to be opened and open together. A third object is to hold the stacks so that they can be exchanged easily and quickly.

(1) Base (1);
A first support trunk (20) that stands upright with respect to the base (1) and is supported by the base (1);
At the upper end, there is a second outer hooking part (41) for hooking the outer surface of the opening edge of the bag, facing the first supporting trunk (20) and between the first supporting trunk (20). A first space supported by the base (1) below the second outer hook (41) so that it can tilt in a direction toward and away from the first support trunk (20) with a space (45) for receiving the 2 trunk support (40);
A first elastic member (43) forcing the second support stem (40) away from the first support stem (20);
There is a first outer hook (24, 25) for hooking the outer surface of the opening edge of the bag facing the second outer hook (41) at the upper part, and the lower part is the first support trunk (20). A bag mouth support member (23) that is supported and inclined in a direction approaching the second outer hook (41) with respect to the first support trunk (20); and
It is inserted into the space between the first support stem (20) and the bag mouth support member (23) from the lower end, and is curved so as to protrude in a direction approaching the bag mouth support member (23). A flexible and elastic bag retainer plate (26), which is pressed against the hooks (24, 25) and whose upper end is fixed to the first support stem (20);
A bag support stand.

  In addition, in order to make an understanding easy, the code | symbol of the corresponding element of the Example shown in drawing and mentioned later is added to the parenthesis by reference for reference. The same applies to the following.

  The bag is lowered into the space (45) from the bottom side, and the upper opening edge is inserted between the bag holding plate (26) and the first outer hooks (24, 25) and lowered downward, so that the opening edge is The portion is sandwiched between the bag pressing plate (26) and the first outer hooking portion (24, 25) and pressed against the first outer hooking portion (24, 25) by the elasticity of the bag pressing plate (26). That is, a part of the opening edge is sandwiched between the bag pressing plate (26) and the first outer hooking portion (24, 25). Applying a force to the second support stem (40) and pushing it toward the first support stem (20), the opening edge opposite to the sandwiching portion is put on the second outer hooking portion (41) and placed downward. As a result of being lowered, the opposite opening edge is hooked on the second outer hooking portion (41). That is, it is supported by the second outer hook (41). Since the first elastic member (43) forces the second support stem (40) away from the first support stem (20), the opening edge of the bag is the bag holding plate (26) and the second outer hooking portion. At (41), it is supported in a substantially isosceles triangle shape, and is pulled by the elasticity of the first elastic member (43) so as to maintain this shape.

  When putting garbage into the garbage bag, if the opening is widened by hand, or if the object hits the opening edge and force is applied to the opening edge, the second support stem (40) resists the elasticity of the first elastic member (43). And it moves to the direction which approaches a 1st outer hook part (24,25), and avoids applying a strong force to an opening edge. That is, since the support of the opening edge is flexible, the opening edge is not easily detached from the stand and is not easily broken.

  The first outer hooks (24, 25) support a plurality of bag opening edges one after another, and the uppermost first bag opening edge is supported by the second outer hook (41). As a result, only one bag is opened and supported, and the other plurality of bags are suspended from the first outer hooks (24, 25). When you put garbage in the opened bag and remove it from the stand, the second bag opens by supporting the opening edge of the second bag under the bag with the second outer hook (41) To be supported. In this way, a large number of garbage bags can be stacked and held so that the bags can be easily and quickly replaced.

  (2) A plurality of first outer hooks (24, 25) are arranged in the horizontal direction (x) perpendicular to the tilt of the second support stem (40); the bag support stand according to (1) above .

  By using a plurality of first outer hooks (24, 25), a plurality of bags can be supported side by side. For example, after supporting the opening edge of the first bag with one of the first outer hooks (24, 25) (24) and the second outer hook (41), the opening edge of the second bag Is supported by the other one (25) of the first outer hook part (24, 25), and the second outer hook part is overlapped with the opening edge of the first bag overlying the opening edge of the first bag. By supporting to (41), two bags can be opened and supported side by side. If the number of the first outer hooks (24, 25) is 3 or 4, 3 or 4 bags can be opened and supported side by side.

  (3) The bag according to (1) or (2), further including a second bag mouth support member (27) supported by the first support stem (20) on the back side of the first support stem (20). Support stand.

  According to this, also on the back side of the first support trunk (20), the opening edge of the bag can be supported by the second bag mouth support member (27). The bag can be filled with dust by supporting a part of the opening edge with a hand. In addition, by providing the second second support stem and the second outer hook portion facing the second bag mouth support member (27), that is, the base (1) is symmetrical with respect to the first support stem (20).
