【Example】
The present invention will be described based on examples. FIG. 1 is a perspective view of the embodiment, and FIG. 2 is a perspective view of the embodiment assembled vertically. Note that the vertical relationship in the text will be described with the handle up (FIG. 1, direction A) and the string carrying part down (FIG. 1, direction B). At both ends of the horizontal and upwardly open semi-cylindrical grip portion (2), a lower portion (3) of a semi-funnel shape (a funnel-shaped vertical half-split shape) is directed downward and perpendicular to the grip portion (2). Attachment, a horizontal string carrying part (4) protrudes at the lower end of the descending part (3), and further, from a place slightly away from the descending part of the string carrying part, a string fixing angle (5) is formed on both descending parts. It rises up in an inclined manner with respect to the plane passing through the center of (3). FIG. 3 is a partially cutaway perspective view, but the central portion (8) and the edge (7) in the lateral direction of the grip portion (2) are formed thicker than the portion (10) between the center and the edge. . Since the resistance to bending increases as the distance from the upper and lower centers increases, it is effective to increase the thickness of the central portion (8) (lower portion) and the edge portion (7) (upper portion) if the entire cross-sectional area is the same. is there. This can also be understood from the fact that the beam having the H section is stronger than the rectangular beam. A crescent-shaped rib (9) is provided inside the semi-cylindrical grip (2) to prevent the grip (2) from being deformed by the load and the hand grip against it, this rib being made particularly thin. The crescent shape helps to reduce the pitch of the vertical stacking described later, and as shown in FIG. 5, the handle of the bag can be held by the handle (1). When put on the bag, it helps the bag handle stabilize without escaping to the side.
[0016]
According to the present embodiment, as compared with the conventional handle shown in FIG. 5, there is no sharp portion in the grip portion, and the load is applied to the user's hand on average, and the hand is not painful. Similarly, since the lowering portion (3) has a semi-funnel shape and a curved surface on the center side, the hand in contact with this portion does not hurt. The grip (2) has a semi-cylindrical shape, the descending part (3) has a semi-funnel shape, and the strap fixing angle (5) is inclined with respect to a plane passing through the center of both descending parts (3). Even if there is a stopper knob (6), the mold separation direction can be made in the vertical direction, and if there is an inclined surface (16) on the lower surface of the stopper knob (6), the locking angle (5) of the stringing angle (5) can be reduced. Even if the inclination is small, it is possible to release from the core mold. When the parting direction is the vertical direction, the area occupied by the parting surface is small (50% as compared with the conventional case), so that a larger number can be produced by one molding. As shown in FIG. 2, when stacked vertically, the volume is smaller than in the case of disjoint (when the vertical pitch is about 8 mm, the volume is 30%), not only the cost of storage and transportation is reduced, but also the store Don't waste valuable space around cash registers. When only one loses the load, use two or three in combination in the up and down direction (Fig. 2). Each part such as the grip part, the descending part, the string mounting part, the strap angle, etc. works jointly with the load, It becomes very strong like "Mori Motonari's arrow" .At this time, if you make the height of the crescent rib, the angle and thickness of the strapping angle so that the upper and lower objects adhere to each other, according to the vertical pitch, It is effective.
[0017]
【The invention's effect】
According to the handle of the first aspect, even if the slide portion is not formed in the mold, the string retaining knob can be forcibly removed to open the mold vertically. Since the gripping part is made almost semi-cylindrical with the parting direction up and down, it is possible to form a large number of products with a small occupation area with respect to the parting surface after forcibly removing the retaining knob and providing inexpensive can do. In addition, a large number of moldings can be made in a single molding operation using a mold for injection molding that does not require a slide portion while reducing the occupied area, and is economical. Further, since the lower surface of the retaining knob has a surface inclined with respect to the horizontal plane, it can slide when releasing from the core mold, and can be easily forcibly removed. In addition, when stacked vertically, the volume is smaller than in the case of disassembly, which not only reduces the cost of storage and transportation, but also does not waste valuable space around the cash register in the store.
[0018]
According to the handle of claim 2, in particular, the strap can be easily hooked by using the inclination of the strap fixing angle, and the handle can be vertically assembled by using the inclination, and the handle can be pulled out. Even if there is an aneurysm, the sliding part is unnecessary and the parting direction can be made up and down.
[0019]
According to the handle of the third aspect, in particular, the grip portion of the handle can be made substantially semi-cylindrical so that the load can be applied to the user's hand widely and evenly, and the inner crescent-shaped rib can form a semi-cylindrical shape. In addition to being able to reinforce, this handle can be assembled vertically.
