Abstract
Description
- The present disclosure relates to a caddy for holding items including needles for sewing. More particularly, the present disclosure relates to a caddy for holding elongated items that are attracted to magnets.
- Conventionally, handicraft needles such as sewing needles or dress pins are stored, when not in use, as stuck on the stuffing of a pin cushion. As a different type from this, JP-A-2017-95826 discloses a holder that uses the attraction force of a magnet.
- Generally, in a structure for holding a plurality of needles using the attraction force of a magnet, a lot of needles tend to overlap on the attracting surface. In such a case, it is difficult to remove the needles one by one from the attracting surface. In this respect, the conventional holder still has room for improvement.
- The caddy for sewing items according to the present disclosure has been proposed in view of these circumstances. It is therefore an object of the present disclosure to provide a caddy that can attract and hold a plurality of products such as sewing needles so as not to overlap with each other.
- A caddy for sewing items provided according to an embodiment of the present disclosure includes a hollow housing; an elongated first permanent magnet contained in the housing; and an elongated second permanent magnet contained in the housing, where the second permanent magnet is arranged in parallel to and spaced apart from the first permanent magnet. The housing includes a first attracting surface, a second attracting surface, and an elongated groove positioned between the first and the second attracting surfaces. The first permanent magnet has an upper surface S-pole corresponding in position to the first attracting surface. The second permanent magnet has an upper surface N-pole corresponding in position to the second attracting surface. The groove extends in parallel to the first and the second permanent magnets as viewed in plan. The groove includes a first longitudinal edge connected to the first attracting surface and a second longitudinal edge connected to the second attracting surface. Each of the first and the second longitudinal edges is curved in such a manner that a center portion thereof is higher than other portions as viewed in a separating direction in which the first and the second permanent magnets are spaced apart from each other.
- Other features and advantages will become apparent from the detailed description given below with reference to the accompanying drawings.

As an example, each of thepermanent magnets permanent magnets surfaces surfaces permanent magnets surfaces - As described above, in the present embodiment, the attracting
surfaces surfaces surfaces FIGS. 5 and 7 ), the inclination angle of each attractingsurface 125, 126 (the angle of an inclined flat face on the right side or left side of the center) may be in the range of 2 to 3 degrees with respect to the horizontal plane. - In this embodiment, as shown in
FIGS. 4 and 6 , each attractingsurface groove 127. Each attractingsurface - The cover 2 can be attached so as to cover the upper portion of the main body 1. The cover 2 has a
ceiling portion 20 that is an upper portion and askirt portion 21 that is a lower portion. Theceiling portion 20 is heart shaped as viewed in plan. Theskirt portion 21 extends downward from the periphery of theceiling portion 20 and is curved. The cover 2 may be made of a synthetic resin having an appropriate strength. -
FIGS. 8 and 9 show the state in which the cover 2 is attached to the main body 1. In this state, a space is defined between theceiling portion 20 of the cover 2 and the main body 1 (theupper wall 121 of the upper case 12). In the present embodiment, theceiling portion 20 covers theupper wall 121 as spaced apart from the main body 1 (theupper wall 121 of the upper case 12). - In
FIGS. 8 and 9 , theskirt portion 21 covers the almostentire side wall 122 of theupper case 12 and a part of theside wall 112 of the lower case 11 (see alsoFIG. 1 ). That is, theskirt portion 21 partially covers the curved side surface of the main body 1. Theskirt portion 21 has an inner circumferential surface formed with a plurality of engagement projections 211 (FIG. 9 ) at appropriate positions. In attaching the cover 2, eachengagement projection 211 engages with the oneengagement groove 17 of the main body 1. Theskirt portion 21 is provided with at least onecutout 212. As shown inFIGS. 1 and 2 , thecutout 212 is formed in such a manner as to break the continuity of the lower edge of theskirt portion 21 and exposes a part of theside wall 122 of theupper case 12. In the present embodiment, as shown inFIG. 8 , theskirt portion 21 is formed with twocutouts 212 spaced apart from each other in the direction x. - The use and advantages of the above-described caddy A are described below with reference to
FIGS. 10 and 11 . In these figures, dress pins N are exemplarily shown as a plurality of products held on the caddy A. As will be easily understood, the present disclosure is not limited to this example, and other kinds of products can also be held by the caddy A. Since the caddy A uses a magnetic force to hold products, the target products are things that are attracted to magnets (ferromagnetic materials). Examples of ferromagnetic metal elements include Fe, Ni and Co. Products made of a material containing these metal elements (e.g. alloys or compounds) can be held by the caddy A. - In use of the caddy A, a dress pin N is placed on the placement surface (the upper surface of the
upper wall 121, including the attractingsurfaces 125 and 126) of the main body 1. In the example shown inFIGS. 10 and 11 , a plurality of dress pins N are attracted to and held on the placement surface. - In placing another dress pin N on the placement surface of the main body 1, the dress pin N is instantaneously attracted to and held on the attracting
surfaces permanent magnets permanent magnets permanent magnets groove 127 is provided, a space is defined between the attracted dress pins N and the main body 1. Thus, in removing each dress pin N from the attractingsurfaces - The magnetic force acting between the magnetic pole surfaces 15 a and 16 a of the
permanent magnets permanent magnets surfaces surfaces FIGS. 10 and 11 , when a plurality of dress pins N are placed on theupper wall 121, these dress pins N are held on the attractingsurface upper wall 121, these dress pins N are prevented from gathering on the attractingsurfaces - In the present embodiment, each attracting
surface groove 127 as seen in the direction y (seeFIG. 6 ). This arrangement prevents an excessive attracting and holding force from acting on the dress pins N placed on the attractingsurfaces longitudinal edges surfaces - The inner circumferential surface of the
skirt portion 21 of the cover 2 has engagement projections 211 (FIG. 9 ). Further, the outer circumferential surface of the main body 1 has theengagement groove 17 with which theengagement projections 211 are engageable. This arrangement prevents the cover 2 attached to the main body 1 from being unintentionally detached from the main body 1. The cover 2 has a cutout 212 (seeFIGS. 1, 2 and 8 ). According to this arrangement, in detaching the attached cover 2 from the main body 1, the cover 2 can be easily detached from the main body 1 by putting a finger on the portion exposed through thecutout 212. - In the foregoing embodiment, the caddy A provided with the cover 2 is described. Unlike this, the caddy for sewing items may not be provided with the cover 2 but may consist solely of the main body 1.
- The caddy for sewing items of the present disclosure is not limited to the foregoing embodiment. The specific structure of each part of the caddy for sewing items may be varied in various ways without departing from the scope defined by the claims.
