Description

The present invention relates to a support assembled from a single sheet.

Conventionally, there has been known a technique for assembling a support that serves as a handle (handle) for various instruments such as a spoon from a single sheet that forms a flat state. For example, Patent Document 1 discloses a technique for assembling a handle portion (support) of a spoon by folding a plurality of handle pieces provided on one sheet and fixing them with a locking portion.

Japanese Unexamined Patent Publication No. 10-38660

By the way, in the handle portion described in Patent Document 1, the gap between the handle pieces is exposed to the outside at the end portion (handle end) on the opposite side to the tip side where the measuring portion for scooping powder is provided. Therefore, when a user's finger or the like gets into this gap, the fixing by the locking portion may be unintentionally released. Therefore, the conventional support has room for improvement in that it may cause deterioration in shape retention and grip (easiness to hold).

This case was devised in view of the above-mentioned problems, and one of the purposes is to suppress deterioration of shape retention and grip in a support assembled from one sheet. Not limited to this purpose, it is also possible to exert actions and effects derived from each configuration shown in the "mode for carrying out the invention" described later, which cannot be obtained by the conventional technique. It can be positioned as another purpose.

The support in this case is a support assembled from a single sheet and having a head having a predetermined function provided on one side in the longitudinal direction, and is connected to each other via a base extending in the longitudinal direction. A pair of side surface portions are bent in the same direction from the base portion to face each other in the lateral direction, and at least one main body portion having a slit formed in the side surface portion and the main body portion on the other side in the longitudinal direction are connected to the main body portion. It is provided with a lid portion that covers the main body portion from the other side, and an insertion portion that is bent from the lid portion to the one side and inserted into the slit from the outside of the main body portion.

According to this case, in a support assembled from one sheet, deterioration of shape retention and gripability can be suppressed.

In each of the following embodiments, a support functioning as a handle of a spoon will be described as an example. Further, the direction orthogonal to the longitudinal direction of the support having an elongated shape is also referred to as "short direction".

[1. First Embodiment]
[1-1. Constitution]
As shown in FIG. 1, the support 5 according to the present embodiment has an elongated shape and functions as a handle of a spoon. The support 5 is assembled from a single sheet 50 (see FIG. 2). The support 5 and the sheet 50 are made of, for example, paper.

A dish-shaped head 4 having a function of scooping an object (predetermined function) is provided on one side (hereinafter, also referred to as “tip side”) of the support 5 in the longitudinal direction D1. Here, the support 5 integrally formed with the head 4 is illustrated as an instrument. That is, the support 5 and the head 4 exemplified here are instruments formed of a single sheet 50.
The support 5 includes a main body portion 1 extending in the longitudinal direction D1, a lid portion 2 connected to the main body portion 1 on the other side (hereinafter, also referred to as “terminal side”) of the longitudinal direction D1, and a tip from the lid portion 2. It is provided with an insertion portion 3 bent to the side. In the support 5, the main body 1 has a handle and the lid 2 has a handle.

The main body 1 is provided with a pair of side surface portions 12, 13 connected to each other via a base portion 11 extending in the longitudinal direction D1. The side surface portions 12 and 13 are bent from the base portion 11 in the same direction (one side of the thickness direction D3 orthogonal to both the longitudinal direction D1 and the lateral direction D2) and face each other in the lateral direction D2. In the present embodiment, the main body portion 1 in which the linearly formed base portion 11 and the side surface portions 12 and 13 have a cross-sectional shape approximately V-shaped (cross-sectional V-shaped) along the longitudinal direction D1 and the lateral direction D2. Is illustrated.

The side surface portions 12 and 13 are closer to each other toward the end side, and are in contact with each other at the position on the most end side (the position covered by the lid portion 2). Further, a head portion 4 is continuously provided on the tip end side of the side surface portions 12 and 13 of the present embodiment.
Hereinafter, when the pair of side surface portions 12 and 13 are distinguished from each other, one side surface portion 12 located on the front side (one side in the lateral direction D2) is also referred to as a "first side surface portion 12" in FIG. The other side surface portion 13 located on the back side (the other side in the lateral direction D2) in 1 is also referred to as a “second side surface portion 13”.

A slit 14 is formed in at least the first side surface portion 12 of the pair of side surface portions 12, 13. In the present embodiment, the main body portion 1 in which the slit 14 is formed only in the first side surface portion 12 is illustrated. In other words, the slit 14 is not formed in the second side surface portion 13 of the present embodiment.
The slit 14 extends from the intermediate portion of the first side surface portion 12 to the end edge 15 (hereinafter, also referred to as “side edge edge 15”) opposite to the base portion 11. Here, an arc-shaped slit 14 having a gently convex shape toward the end side is illustrated.

The first side surface portion 12 of the present embodiment is slightly bent by a fold curve 16 extending in a straight line, and is slightly convex toward the outside in the lateral direction D2. In detail, the folding curve 16 is a straight line connecting the position on the most terminal side of the connection portion between the first side surface portion 12 and the base portion 11 and the end portion of the slit 14 on the base portion 11 side. It is extended to the side edge 15. By bending the first side surface portion 12 along the folding curve 16 as described above, the swelling of the portion located on the side edge 15 side (one side of the thickness direction D3) of the folding curve 16 is suppressed.

Similarly, the second side surface portion 13 of the present embodiment is slightly bent by the folding curve 16 of the first side surface portion 12 and the mirror-symmetrical folding curve 17 (see FIG. 2), and is oriented toward the outside in the lateral direction D2. It is slightly convex. By bending the second side surface portion 13 along the folding curve 17 in this way, the swelling of the portion located on the side edge 15 side (one side of the thickness direction D3) of the folding curve 17 is suppressed.
The lid portion 2 is arranged on the terminal side of the main body portion 1 and covers the main body portion 1 from the terminal side. In the present embodiment, the lid portion 2 connected to the second side surface portion 13 (any of the pair of side surface portions 12 and 13) is illustrated. The lid portion 2 connected to the second side surface portion 13 covers the end side edge portion of the first side surface portion 12 so as not to be visible from the outside.

The insertion portion 3 is inserted into the slit 14 from the outside of the main body portion 1 in order to maintain the support 5 in a three-dimensional shape (assembled state). The insertion portion 3 is locked to the main body portion 1 by being inserted into the slit 14.
The support 5 is provided with the same number of insertion portions 3 as the slits 14. Since the support 5 of the present embodiment is provided with only one slit 14, only one insertion portion 3 is provided. Further, in the support 5 of the present embodiment, since the slit 14 is provided in the first side surface portion 12, the insertion portion 3 is inserted into the slit 14 from the outside of the first side surface portion 12. Here, an insertion portion 3 having a tapered shape (triangular shape in the present embodiment) in order to improve the insertion property into the slit 14 is illustrated.

The insertion portion 3 of the present embodiment has a step portion 31 that is locked to the slit 14. The step portion 31 is formed at the end edge of the insertion portion 3 on the base portion 11 side. The step portion 31 is caught in the slit 14 to prevent the insertion portion 3 from coming off.
Further, the insertion portion 3 of the present embodiment is slightly bent by a folding curve 32 extending in an arc shape similar to the slit 14, and is slightly convex toward the outside in the lateral direction D2. By bending the insertion portion 3 along the folding curve 32 in this way, the portion on the insertion end side (right side in FIG. 1) of the folding curve 32 can easily enter the inside of the first side surface portion 12.

FIG. 2 is a plan view of a sheet 50 assembled on a spoon to which the support 5 of the present embodiment is applied (a developed view of the spoon to which the support 5 is applied). Hereinafter, among the directions along the extending surface of the sheet 50, the direction in which the base portion 11 extends is also referred to as a vertical direction D4, and the direction orthogonal to the vertical direction D4 is also referred to as a horizontal direction D5. With the base 11 as a reference, the vertical direction D4 and the horizontal direction D5 of the sheet 50 correspond to the longitudinal direction D1 and the lateral direction D2 of the support 5, respectively.

In the sheet 50, the base portion 11 is provided in the center of the lateral direction D5, and the side surface portions 12 and 13 are continuously provided on both sides of the lateral direction D5 of the base portion 11. Further, a head portion 4 is continuously provided on one side (corresponding to the tip end side of the support portion 5) of the base portion 11 and the side surface portions 12 and 13 in the vertical direction D4. Further, a lid portion 2 is continuously provided on the other side of the second side surface portion 13 in the vertical direction D4 (corresponding to the terminal side of the support portion 5). Then, the insertion portion 3 extends from the lid portion 2 toward the other side in the vertical direction D4.
The base 11 and the folding curves 16, 17, and 32 of the sheet 50 are all composed of ruled lines (grooves) that assist in bending. Further, a ruled line is also provided at the boundary between each of the side surface portions 12 and 13 and the head portion 4. In FIGS. 2 and 4 and 6 described later, the ruled lines are shown by thin lines.

In the sheet 50 of the present embodiment, a ruled line 21 (hereinafter, also referred to as “cover ruled line 21”) is provided at a portion corresponding to the lid portion 2. The lid ruled line 21 has an end on the base 11 side (right side in FIG. 2) with respect to the end on the end side of the base 11 (a portion where the folded curves 16 and 17 are connected) according to the thickness dimension of the sheet 50. It is separated to the other side of D4 in the vertical direction. The lid ruled line 21 is arranged on the terminal side of the support 5.

[1-2. Action and effect]
(1) According to the support 5, the support 5 is maintained in a three-dimensional state by inserting the insertion portion 3 bent from the lid portion 2 connected to the main body portion 1 into the slit 14, so that the support 5 is supported. The grip (easy to hold) of the body 5 can be improved. As a result, even if an instrument to which the support 5 is applied (a spoon in this embodiment) is once placed on a table or the like, the support 5 is maintained in a three-dimensional state, so that it is easy to hold the instrument again. Become. Further, since the lid portion 2 covers the main body portion 1 from the terminal side, the user's finger or foreign matter (dust, moisture, etc.) can be prevented from entering the main body portion 1 from the terminal side, so that the insertion is not intended. It is possible to suppress the omission of the part 3. Therefore, in the support 5 assembled from one sheet 50, deterioration of shape retention and gripability can be suppressed.

(2) The slit 14 is formed only on the first side surface portion 12, and the lid portion 2 is connected to any of the pair of side surface portions 12 and 13 (second side surface portion 13 in this embodiment), and the insertion portion 3 is provided. According to the support 5 provided with only one, the main body portion 1 can be maintained in a three-dimensional state by one slit 14 and one insertion portion 3. Therefore, the gripability of the support 5 can be improved with a simple structure as compared with the case where a plurality of the slits 14 and the insertion portions 3 are provided. Further, according to the main body portion 1 in which the slit 14 is formed only on one of the side surface portions 12 and 13 (not formed on the other side), compared with the case where the slit 14 is formed on both of the side surface portions 12 and 13. Therefore, the decrease in rigidity can be suppressed, and the number of slits 14 is reduced, so that foreign matter can be suppressed from entering the main body 1 from the slits 14.

(3) According to the support 5 in which the lid portion 2 is connected to the second side surface portion 13 and the insertion portion 3 is inserted into the slit 14 from the outside of the first side surface portion 12, the insertion portion 3 is inserted into the lid portion 2. It is possible to insert the slit 14 into the slit 14 only by bending it once to the outside of the first side surface portion 12 on which the slit 14 is formed. Therefore, the ease of assembling the support 5 into a three-dimensional state (hereinafter, also referred to as “assembly work”) can be enhanced.

(4) According to the main body portion 1 having a V-shaped cross section with the linearly formed base portion 11 and the pair of side surface portions 12 and 13, the support 5 has a width in the lateral direction D2 (4). The dimension (width dimension) in the lateral direction D2 can be suppressed on the base 11 side (while making the support 5 a three-dimensional shape). Therefore, it contributes to compactification while improving the gripability of the support 5.

(5) According to the insertion portion 3 having the step portion 31, the insertion portion into the slit 14 is easily maintained by engaging the step portion 31 with the slit 14, so that the support 5 is more stable. Can be maintained in a three-dimensional state. Therefore, it is possible to further suppress the deterioration of the shape retention and gripability of the support 5.

(6) If the side surface portions 12 and 13 are bent toward the lateral sides D2 by being bent along the folding curves 16 and 17, respectively, the portion on the side edge 15 side of the folding curves 16 and 17 is formed. In, the swelling of the main body 1 in the lateral direction D2 can be suppressed. Therefore, it contributes to the compactness of the support 5, and the insertion portion 3 tends to overlap the outside of the side surface portions 12 and 13, so that the ease of inserting the insertion portion 3 into the slit 14 can be enhanced. Further, by improving the ease of inserting the insertion portion 3 in this way, the ease of assembly work can be improved, and the support 5 can be maintained in a more stable three-dimensional state. It is possible to further suppress deterioration of shape retention and grip.

(7) If the insertion portion 3 is bent along the folding curve 32 to form a protrusion toward the outside in the lateral direction D2, the portion on the insertion end side of the folding curve 32 is the first side surface portion 12. Since it is easy to enter the inside, the ease of inserting the insertion portion 3 into the slit 14 can be improved. By improving the ease of insertion of the insertion portion 3 in this way, the ease of assembly work can be improved as described above, and the support 5 is more stably maintained in a three-dimensional state, so that the support 5 It is possible to further suppress the shape retention and gripability of the.

(8) In the sheet 50 of the present embodiment, the end portion of the lid ruled line 21 provided at the position corresponding to the lid portion 2 on the base portion 11 side has a thickness of the sheet 50 with respect to the end portion on the end side of the base portion 11. Since they are separated accordingly, the lid portion 2 can be appropriately arranged on the terminal side of the base portion 11 in the support portion 5. As a result, the main body 1 is more reliably covered by the lid 2 from the terminal side, so that it is possible to more reliably prevent the user's fingers or foreign matter from entering the main body 1 from the terminal side.

[2. Second embodiment]
[2-1. Constitution]
As shown in FIG. 3, the support 6 according to the present embodiment mainly differs from the support 5 described in the first embodiment in the configuration of the insertion portion 3. Hereinafter, the same or corresponding elements as those described in the first embodiment will be designated by the same reference numerals, and duplicate description will be omitted.
