All of the drawings show examples of embodiments of the retainer of the present invention.

(1) The retainer H is for suspending the target object J while holding the holding target portion J2 along the upper edge of the substantially vertical sheet-like portion J1 of the target object J. A support S that supports J upward and a holder F that holds an object J between the support S are rotatably connected to each other at the bottom. In this specification, the expression of the vertical positional relationship is based on the upright state.

(2) The object J in this example is a synthetic resin film bag (garbage storage bag). It is a part along

(3) The support S has a ridge S1 and a support opening S2.

(3-1) The ridge portion S1 of the support S is a substantially bag-like portion for being supported, which is formed by folding downward the upper edge portion of the sheet-like portion of the holding target portion J2 of the object J to form a downward opening. It is for supporting the inside upward, and projects upward and extends along a straight line in the horizontal direction when in use. The upper surface portion of the ridge portion S1 has a constant width.

In order to support the bag as the object J in the open state, the ridge S1 extends along a straight line in the horizontal direction to about one-sixth of the length of the entire circumference of the opening of the bag.

(3-2) Along the entire length of the ridge S1, there is a laterally long support opening S2 that opens only on one side of the ridge S1 (on the right side in FIG. 2). The support opening S2 is provided at its upper portion with a downward opening recess S3 that extends substantially along the entire length of the ridge S1.

The downward opening concave portion S3 opens downward when the holding target portion J2 of the object J is held, and has a groove shape parallel to the ridge portion S1.

(3-3) Both ends of the support lower portion S4 below the support opening S2 of the support S are located inward of the both ends of the ridge S1 in the direction in which the ridge S1 extends. One side and the other side have a cutout portion S5a opening on the one side and a cutout portion S5b opening on the other side, respectively. The upper edge portion of the sheet-like portion of the portion to be held J2 is folded downward to form a downward opening, and the portion thereof is inserted into the notch portion S5a and the notch portion S5b and latched.

The opening P of the notch S5a and the notch S5b is narrow, and both sides sandwiching the opening have a substantially hook-shaped cross section that is folded back toward the inside of the notch through the opening from above or below. Also, it is easy to prevent a part of the substantially bag-like portion to be supported that has entered the inside of the notch portion S5b from being separated from the opening portion P.

(4) The holder F has a holder fitting portion F1 that fits into the support opening S2 in a state in which the holding target portion J2 of the object J is held. The body opening S2 includes an upward projection F2 that protrudes into the lower opening recess S3 and is parallel to the lower opening recess S3 and the projection S1.

(4-1) The ridges S1 of the support S support upward the inside of the substantially bag-like portion to be supported in the object J, and hold the downward folded portion of the substantially bag-like portion to be supported. The body fitting portion F1 is fitted into the support opening S2 and the upward protrusion F2 protrudes upward into the lower opening recess S3, so that the support opening S2 and the groove-like lower opening recess S3 are held together. The holding target portion J2 is held in a state of being sandwiched between the body fitting portion F1 and the ridge-like upward projection portion F2.

(4-2) Since the retainer fitting portion F1 is fitted into the support opening S2 and the upward protrusion F2 protrudes upward in the lower opening recess S3, the holding object J is held. By supporting and suspending the retainer H upward from the retainer F, the retainer fitting portion F1 is prevented from being disengaged from the support opening S2, and the holding target portion J2 of the object J is prevented from being released. Retention is reliably maintained.

It is possible to hold the holding target part J2 along the upper edge of the substantially vertical sheet-like part J1 in the bag made of synthetic resin film and hang the bag in an open state, so that the bag can be used for picking up garbage (or for other purposes). ) can be suitably used.

(4-3) On the upper part of the holder F, there is provided an annular handgrip portion G that protrudes upward in parallel with the upward protrusion F2. By suspending the retainer H holding the object to be held J by the grip portion G, the retainer H can be supported upward by the holder F and suspended.

(4-4) A predetermined part A, which is one end of the link body L, is coupled to the lower part of the holder F so as to be rotatable in the direction of the arrow in FIG. A predetermined part B, which is the other end of the link body L, is rotatably coupled to the lower part of the body S. As shown in FIG.

When the retainer fitting portion F1 is fitted into and disengaged from the support opening S2, the predetermined portion A rotates in the direction of the arrow in FIG. The length between the contact position C and the predetermined portion A and the predetermined portion A and the predetermined portion B of the link body L are longer than the length of the straight line connecting the position C rotating and contacting S2 and the predetermined portion B of the link body L. The sum of the lengths between the In a state where the straight line is elastically overcome and the predetermined portion A is positioned on the side of the holder F, the engagement between the holder fitting portion F1 and the support member opening S2 is released.

[2] Embodiments of the present invention, including forms other than those described above, will be further described.

(1) The retainer of the present invention is for suspending an object while holding a portion to be held along the upper edge of a substantially vertical sheet-like portion of the object. A supporting body for supporting and a holding body for holding an object between the supporting bodies are connected.

The support and holder can, for example, be rotatably connected to each other at the bottom, but this is not necessarily the case.

The retainer of the present invention may also comprise two or more pairs of supports and retainers horizontally adjacent in series or spaced apart.

(2) The object is mainly a bag-like body, especially a bag made of synthetic resin film, and its use is mainly a garbage bag, but the material, shape, use, etc. are not limited to this.

(3) The support has a ridge and a support opening.

(3-1) The ridge portion of the support is formed by folding downward the upper edge of the sheet-like portion of the holding target portion of the object, thereby forming a downwardly opening opening upward. For support, it protrudes upward (in use) and extends in a generally horizontal direction.

The ridge can be along a generally horizontal straight or curved line. The protruding portion may be divided into a plurality of portions along a substantially horizontal straight line or curved line.

The upper surface of the ridge may have a constant width, but is not necessarily limited to this. In addition to being planar, the upper surface of the ridge may be curved upward or may have a polygonal cross section perpendicular to the direction in which the ridge extends. Further, the upper surface portion of the ridge portion may be formed such that unevenness is repeated in the direction in which the ridge portion extends, or a vertical wave shape may be formed.

In order to support the bag-shaped body as an object in an open state, the ridges are provided at least at two locations separated in the horizontal direction to some extent (for example, two locations separated from each other, or a continuous portion extending over the two locations). In the above, it is preferable that the inside of the substantially bag-like portion to be supported is supported upward. The length of two points separated in the horizontal direction to some extent is, for example, about 1/10 to 1/3, preferably 1/8 to 1/4, of the length of the entire circumference of the opening of the bag-shaped body as the object. about one-third.

(3-2) On the underside of the ridge, there is a support opening that opens to one side of the ridge and has a downwardly opening concave portion at the top.

The support opening does not necessarily have to open only on one side of the ridge. Also, the support opening can be located on the lower side along the entire length of the ridge, for example.

For example, the downwardly opening concave portion may extend over substantially the entire length of the upper portion of the support opening, and may be divided into two or more in the direction of the ridge portion. Further, the downward opening concave portion can be, for example, a groove-like shape parallel to the ridge portion.

(4) The holder has a holder fitting portion that fits into the opening of the support while holding the portion to be held of the object, and the holder fitting portion fits into the opening of the support. An upward protrusion is provided that protrudes into the recess in the downward opening in the closed state.

(4-1) The ridge portion of the support supports upward the inside of the supported substantially bag-shaped portion of the object, and the downward folded portion of the supported substantially bag-shaped portion is engaged with the holder. is fitted into the support opening and the upward protrusion protrudes upward into the lower opening recess, thereby providing a The part to be held of the object is held in a sandwiched state.

For example, a substantially vertical sheet-like portion in a bag made of synthetic resin film (or other material) (a substantially vertical sheet-like portion in the state where the bag is suspended at the opening, for example, the front [or other part] substantially vertical sheet-like portion ), for example, by holding the part to be held along the upper edge of the bag in an open state by holding it at two continuous portions (at least, at least two points separated in the horizontal direction) over two points separated in the horizontal direction. be able to. This makes the bag suitable for picking up trash (or other uses).

(4-2) Since the retainer fitting portion is fitted in the support opening and the upward projection projects upward in the lower opening recess, the object to be held is supported upward by the retainer. By suspending the object holding the , it is possible to effectively prevent the release of the engagement of the holder fitting portion with the support opening, and the holding of the holding target portion of the object is more reliably maintained.

(4-3) It is desirable that the holding member has a hand grip.

For example, the grip portion can be positioned above the holder or above the ridge portion of the support when the holding target portion of the object is held.

(4-4) The retainer of the present invention has, for example, the following fitting and holding mechanism for holding and releasing the fitted state between the holder fitting portion and the support opening. be able to.

For example, a predetermined portion A (for example, one end) of the link body is rotatably coupled to the lower portion of the holder, and a predetermined portion B (for example, a The other end) is rotatably coupled, and when the holder fitting portion is fitted into and disengaged from the support opening, the upper portion of the holder fitting portion is (generally rotatable) with respect to the support opening. than the length of the straight line connecting the contact position C and the predetermined part B of the link body, the sum of the length between the contact position and the predetermined part A and the length between the predetermined part A and the link body B The holder fitting portion and the support opening are held in a fitted state in a state where the predetermined portion A is located closer to the support side than the straight line, and the predetermined portion A crosses over the straight line elastically. The fitting between the holder fitting portion and the support opening may be released in a state of being positioned on the holder side.

Alternatively, for example, one or two or more protrusions, at least one of which can be elastically deformed, and recesses into which the protrusions can be fitted are provided in the support and the holder, respectively, and the holder fitting portion supports the support. In the state of being fitted in the body opening, the projection and recess are fitted and fixed to maintain the fitted state of the holding body fitting part and the support body opening, and the necessary fitting releasing force is applied. It is also possible to use a snap lock (snap lock) that allows the retainer fitting portion to be disengaged from the support opening by releasing the engagement between the convex portion and the concave portion, but is limited to these. It is not something that can be done.

(5) On one side and the other side in the direction in which the ridge extends in the lower part of the support (for example, below the opening of the support) , each of which has a notch portion opening to the one side or the lower side and a notch portion opening to the other side or the lower side for hooking the sheet-like portion in the portion to be held. The part where the upper edge of the sheet-like part in the part is folded downward, especially the part that forms a downward opening is inserted into the notch and hooked to facilitate the work of holding the part to be held and to hold it. can be more certain.

The opening of the notch is preferably narrow in order to ensure more reliable hooking. 3) By having a substantially hook-shaped cross section that is folded toward the inside of the notch through the opening, a part of the supported substantially bag-shaped part that has entered the inside of the notch is separated from the opening. On the contrary, it is preferable that a part of the supported substantially bag-shaped portion is prevented from entering the inside of the notch from the opening as much as possible.
