Further, the size of the base plate 12 may be formed so as to close part of the first and second holes 32 and 34.

  The locking portions 14a and 14b are provided with tongue-shaped tongue piece members 18a and 18b in which a part of the base plate 12 is cut out by the groove 15, projecting members 19a and 19b, and finger hook portions 19c and 19d, respectively. .

  The tongue piece members 18a and 18b are formed at a predetermined angle with respect to the longitudinal direction of the flange portion 11, for example, 90 degrees in this embodiment. The length in the longitudinal direction of the tongue piece members 18 a and 18 b is slightly longer than the length in the longitudinal direction of the hole 32. Further, the corner portions of the tongue piece members 18a and 18b are rounded so that the insertion into the hole portion 32 is easy. In the tongue-shaped tongue piece members 18a and 18b, projecting members 19a and 19b that are detachably locked to the first hole 32 are formed on the back side (flange portion 11 side) shown in FIG. The

  The angle of the tongue piece members 18a and 18b with respect to the longitudinal direction of the flange portion 11 is such that when the flange portion 11 and the base plate 12 are locked in the first hole portion 32, the first and second packaging members are used. The angle is not limited to 90 degrees of the present embodiment as long as the materials 31 and 33 can be engaged with each other. Further, the width of the groove 15 is formed such that when the base plate 12 is rotated, the positions of the holes 32 and 34 are visible.

  The projecting members 19a and 19b are formed, for example, in a substantially T shape, and are provided near the tips of the tongue piece members 18a and 18b. The length H in the longitudinal direction of the projecting members 19a and 19b is equal to the length in the longitudinal direction of the holes 32 and 34 (see FIG. 8). Further, the width D of the projecting members 19a and 19b is equal to the width of the hole portions 32 and 34 (see FIG. 8). The projecting members 19 a and 19 b are detachably locked in the first hole 32 by rotation around the connection portion 13 of the engagement holder 10. When the projecting members 19 a and 19 b are locked in the first hole portion 32, the base plate 12 engages the first and second packaging materials 31 and 33 together with the flange portion 11.

  The projecting members 19a and 19b may be formed to be detachably locked not only to the first hole 32 but also to the second hole 34. Further, the shape of the projecting members 19a and 19b is not limited to the T shape, and can be formed in an arbitrary shape.

  Further, finger hook portions 19c and 19d are formed on the tongue piece members 18a and 18b. The finger-hanging portions 19c and 19d are notches formed at the tips of the locking portions 14a and 14b and on the back side (flange portion 11 side) shown in FIG. By forming the finger hooks 19c and 19d, a gap is generated between the locking parts 14a and 14b and the first packaging material 31, and the operator can easily hook the tongue pieces 18a and 18b.

  The openings 16 a and 16 b form rectangular windows that are opened near the outer periphery of the base plate 12 and at positions facing the flange 11. By forming the openings 16a and 16b, the front end of the flange portion 11 with the base plate 12 interposed therebetween can be visually observed. As a result, the flange portion 11 can be easily inserted into the hole portion 32. The openings 16a and 16b are not limited to a quadrangular shape, and may be a polygonal shape such as a triangular shape, a circle, or an oval shape as long as the flange portion 11 is visible.

  Further, the finger hooking portion 17 is formed in the center of the base plate 12 and slightly protruding from the front side shown in FIG. The finger hooking portion 17 can be formed in, for example, a mortar-shaped concave shape or a hemispherical convex shape so that the finger can be easily hooked. Here, when the engagement holder 10 is rotated by 90 degrees, the base plate 12 is rotated around the finger hook portion 17. Following this rotation, the connecting portion 13 and the flange portion 11 are rotated 90 degrees, and the first and second packaging materials 31 and 33 can be engaged by the flange portion 11 and the base plate 12.

  The connecting portion 13 is a member that has a cylindrical shape and connects the flange portion 11 and the base plate 12. In the connection portion 13, both ends of the column are provided so as to connect the flange portion 11 and the center position of the base plate 12. The length T of the connecting portion 13 is formed to be slightly longer than the combined length of the first and second hole portions 32 and 34, or the combined length of the depths.

  In addition, the flange part 11, the base board 12, and the connection part 13 which comprise this engagement holder 10 can be integrally shape | molded by injection molding etc. As a result, compared with the case where each part of the engagement holder 10 is manufactured separately, the manufacturing process, the manufacturing time, and the manufacturing cost can be reduced, and the number of parts can be reduced.

Next, the attachment procedure of the engagement holder 10 will be described based on the drawings of FIGS.
First, the worker places his / her finger on the finger rests 17, 19c and 19d. Then, the finger hooks 19c and 19d are pulled forward with the finger hook 17 as a fulcrum. Thereby, the tongue piece members 18a and 18b are warped. Next, the flange portion 11 is inserted into the holes 32 and 34 of the packaging materials 31 and 33 while viewing through the openings 16a and 16b (see FIG. 6).

  When the flange portion 11 penetrates the hole portions 32 and 34 by this insertion, the base plate 12 is then rotated 90 degrees around the finger hook portion 17 (see FIG. 7). At this time, since the tongue piece members 18a and 18b are held in a warped state, contact between the protruding members 19a and 19b and the first packaging material 31 can be avoided. As a result, the engagement holder 10 rotates smoothly around the finger hook portion 17.

  Along with this rotation, the flange portion 11 and the tongue piece members 18a and 18b also rotate. And when it rotates 90 degree | times, the tongue piece members 18a and 18b will move to the position facing the hole part 32. FIG. Here, when the finger is removed from the finger-hanging portions 19c and 19d, the warping of the tongue piece members 18a and 18b returns to the original state, and the projecting members 19a and 19b are moved and locked in the hole portion 32 (see FIG. 8). ). The base plate 12 is brought into contact with the packaging material 31 and the flange portion 11 is brought into contact with the packaging material 33. As a result, the packaging materials 31 and 33 are engaged by the engagement holder 10. In this state, even if an impact is applied to the packaging materials 31 and 33, since the protruding members 19a and 19b are locked in the hole 32, the engagement holder 10 can be prevented from moving or coming off.

  Further, when removing the engagement holder 10 from the packaging materials 31 and 33, the fingers are hooked on the finger hooks 17, 19c and 19d, and the finger hooks 19c and 19d are pulled forward with the finger hook 17 as a fulcrum. Thereby, the tongue piece members 18a and 18b are warped, and the locking state between the projecting members 19a and 19b and the hole 32 is released.

  Next, the base plate 12 is rotated by 90 degrees around the finger hook portion 17. With this rotation, the flange portion 11 is rotated and moved to the positions of the hole portions 32 and 34 of the packaging materials 31 and 33, and can be taken out.

  In this embodiment, when the flange portion 11 is inserted into the hole portions 32 and 34 and the locking portions 14a and 14b are locked to the hole portion 32 in accordance with the rotation operation, the flange portion 11 and the base plate 12 are used. The packaging materials 31 and 33 can be easily engaged. Moreover, at the time of removal, the engagement state of the packaging materials 31 and 33 is facilitated by releasing the engagement state between the engagement portions 14a and 14b and the hole portion 32 and removing the flange portion 11 from the hole portions 32 and 34. Can be resolved. Therefore, even when the engagement holder is subjected to a load due to an impact or the like, the engagement state with the hole portion can be released simply by warping the engagement portion, and the engagement holder can be easily attached to and detached from the object to be engaged.

(Second Embodiment)
A second embodiment of the present invention will be described.
FIG. 9 is a perspective view showing an engagement holder 40 according to the second embodiment of the present invention, FIG. 10 is a front view showing when the engagement holder and the packaging material are attached, and FIG. It is a rear view showing the joint holder and the packaging material after attachment.

The engagement holder 40 includes a flange portion 41, a base plate 42, and a connection portion 43.
Since the flange part 41 and the connection part 43 of this engagement holder 40 are the same structures as the flange part 11 and the connection part 13 of the engagement holder 10, description is abbreviate | omitted here.

  The base plate 42 is different from the base plate 12 of the engagement holder 10 in that the base plate 42 is formed in a square shape. The base plate 42 is formed in such a size that a part of the first and second holes 32 and 34 can be closed when attached to the packaging materials 31 and 33. Here, the 1st and 2nd hole parts 32 and 34 of the 1st and 2nd packaging materials 31 and 33 consist of circular holes 32a and 34a which consist of the same shape, and these circular hole parts 32a and 34a. Convex hole portions 32b, 32c, 34b, 34c projecting in the diameter direction are formed. The convex holes 32b and 32c and the convex holes 34b and 34c are formed to have the same size as or slightly larger than the flange 41. The base plate 42 closes part of the circular hole portions 32a and 34a.

  The base plate 42 is not limited to a quadrangular shape but may be a polygonal shape. The length of the diagonal line of the base plate 42 is preferably set to be longer than the diameter of the circular hole portions 32a and 34a and shorter than the length in the longitudinal direction of the convex hole portions 32b, 32c, 34b and 34c. This setting makes it possible to visually check the convex hole portions 32b and 32c in which projecting members 46a and 46b described later are locked.

The base plate 42 has locking portions 44a and 44b that are detachably locked to the first hole portions 32 (convex hole portions 32b and 32c).
The locking portions 44a and 44b include extendable members 45a and 45b that are extendable, projecting members 46a and 46b, and finger hooks 46c and 46d, respectively.

  The elastic members 45a and 45b are formed at a predetermined angle with respect to the longitudinal direction of the flange portion 11, for example, 90 degrees in this embodiment. The expansion members 45a and 45b are provided in the locking portions 44a and 44b so that they can be expanded and contracted in the longitudinal direction by an expansion / contraction mechanism (not shown) provided in the locking portions 44a and 44b. The extendable members 45a and 45b are removably engaged with the projecting members 46a and 46b in the hole 32. The extendable members 45a and 45b are extended and extended to a length sufficient to hold the projection members 46a and 46b inserted into the holes 32 and retained.

  Since the protrusion members 46a and 46b and the finger hook portions 46c and 46d have the same configuration as the protrusion members 19a and 19b and the finger hook portions 19c and 19d of the engagement holder 10, the description thereof is omitted here.

Next, the attachment procedure of the engagement holder 40 will be described based on the drawings of FIGS.
First, the operator hangs his / her finger on the finger-hanging portions 46c and 46d of the elastic members 45a and 45b. Then, the elastic members 45a and 45b are pushed in the center direction. Thereby, the elastic members 45a and 45b are contracted to shorten the length. Next, the flange part 11 is inserted into the hole parts 32 and 34 (convex hole part 32b, 32c, 34b, 34c) of the packaging materials 31 and 33, seeing visually (refer FIG. 10).

  When the flange portion 11 penetrates the hole portions 32 and 34 by this insertion, the force of the finger hung on the finger hook portions 46c and 46d is weakened. Thereby, the elastic members 45a and 45b extend, and the projecting members 46a and 46b come into contact with the hole portion 32 (circular hole portion 32a) (see FIG. 10). As a result, the engagement holder 40 is held in the holes 32 and 34.

  Next, when the base plate 42 is rotated, the protruding members 46a and 46b slide on the peripheral surface of the circular hole portion 32a. When the base plate 42 is rotated 90 degrees, the elastic members 45a and 45b reach the convex holes 32b and 32c and automatically extend in the longitudinal direction. Due to the expansion of the elastic members 45a and 45b, the projecting members 46a and 46b come into contact with the convex holes 32b and 32c, respectively, and are detachably locked in the first holes 32 (see FIG. 11). The base plate 42 is brought into contact with the packaging material 31 and the flange portion 41 is brought into contact with the packaging material 33. As a result, the packaging materials 31 and 33 are engaged by the engagement holder 40. In this state, even if an impact is applied to the packaging materials 31 and 33, since the protruding members 46a and 46b are locked in the hole portion 32, the engagement holder 40 can be prevented from moving or coming off.

  Further, when removing the engagement holder 40 from the packaging materials 31 and 33, the fingers are hung on the finger hook portions 46c and 46d and pushed in the center direction. Thereby, the elastic members 45a and 45b are contracted, and the locking state between the projecting members 46a and 46b and the hole 32 is released.

  Next, the base plate 42 is rotated 90 degrees. With this rotation, the flange portion 41 rotates and moves to the positions of the holes 32 and 34 (convex hole portions 32b, 32c, 34b, and 34c) of the packaging materials 31 and 33, and can be taken out.

  In the present embodiment, the flange portion 11 is inserted into the hole portions 32 and 34, and the projecting members 46a and 46b are slid into the circular hole portion 32a in accordance with the rotation operation, and the projecting members 46a and 46b become the projecting hole portions 32b and 32c. The packaging materials 31 and 33 can be easily engaged with each other by the flange portion 11 and the base plate 12. Further, at the time of removal, the latching state between the projecting members 46a and 46b and the hole 32 is released, and the flange 41 is taken out from the holes 32 and 34 (convex hole portions 32b, 32c, 34b and 34c), thereby packaging. The engaged state of the materials 31 and 33 can be easily eliminated. Therefore, even when the engagement holder is subjected to a load due to an impact or the like, the engagement with the hole can be released simply by contracting the expansion and contraction member, and can be easily attached to and detached from the object to be engaged.

  Further, in the present embodiment, the projecting members 46a and 46b can be slid into the circular hole portion 32a along with the rotation operation, and when the projecting members 46a and 46b reach the projecting hole portions 32b and 32c, the telescopic member 45a. 45b extend. As a result, the protruding members 46a and 46b are also extended and can be automatically locked to the convex hole portions 32b and 32c.
