[0001] The present disclosure relates to an engagement structure for engaging members with each other.

Background Art

[0002] In order to join members together, a so-called snap-fit structure may be used. In a snap-fit structure, one member and another member can be engaged with each other by a fitting structure or the like, and can be easily joined.

[0003] When this snap-fit structure is adopted, if the engagement release is easy, it is conceivable that the member may be artificially removed from the outside, or the engagement between the members may be inadvertently released. Therefore, a device has been devised to prevent the engagement release from being easily performed.

[0004] In Patent Document 1, a tool for releasing engagement is used to apply force to release the engagement of the clip. In Patent Document 2, heat is applied to the member to deform it, facilitating the release of the engagement. In Patent Document 3, a structure that allows the engagement to be released using a dedicated tool is adopted.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the conventional technology, it is necessary to use a dedicated tool or thermal deformation, and further ease of engagement release is required.​​ This disclosure aims to provide an engagement structure that can be easily disengaged without the use of special tools or thermal deformation, while suppressing manual disengagement from external sources or unintentional disengagement. [Means for solving the problem]

[0008] To achieve the above objective, the engagement structure according to the first embodiment comprises: a plurality of engaged portions formed on a first member; a second member that covers at least a part of the first member and has a plurality of engaging portions formed thereon that engage with the engaged portions, and is attached to the first member; and a handle portion that connects the plurality of engaging portions to each other and is arranged in an inner space formed between the first member and the second member, and when the second member moves in a direction that removes it from the first member, it applies a force to the plurality of engaging portions in a direction that disengages them from the engaged portions.

[0009] In the engagement structure according to the first embodiment, the second member is attached to the first member by the engagement of a plurality of engaged portions formed on the first member and a plurality of engaging portions formed on the second member. The plurality of engaging portions of the second member are connected to each other by a handle portion.

[0010] By moving the handle portion in the direction that the second member is detached from the first member, a force is applied to the multiple engaging portions in the direction that disengages them from the engaged portions. Therefore, by moving the handle portion in this direction, the engagement can be easily released.

[0011] Furthermore, since the handle portion is positioned in the inner space formed between the first member and the second member, it is possible to prevent the engagement between the engaging portion and the engaged portion from being released due to unintentional force being applied to the handle portion.

[0012] In the engagement structure according to the second embodiment, the engagement portions are provided at positions that face each other with the handle portion in between.

[0013] As in the engagement structure according to the second embodiment, by providing engagement parts at positions opposite each other with the handle in between, force can be applied to each engagement part in a balanced manner as the handle moves.

[0014] In the engagement structure according to the third embodiment, the second member has an opening formed therein that allows access to the handle portion from the outside.

[0015] According to the engagement structure of the third embodiment, the handle portion can be accessed from the opening and operated to release the engagement.

[0016] The engagement structure according to the fourth embodiment further comprises an openable and closable opening / closing member that covers the opening.

[0017] According to the engagement structure of the fourth embodiment, since the opening is covered by the opening / closing member, it is possible to more reliably prevent force from being unintentionally applied to the handle portion.

[0018] In the engagement structure according to the fifth embodiment, a screw hole is formed in the handle portion, and a screw member, supported by an opening in the second member and with its screw head exposed from the opening, is screwed into the screw hole, and rotation of the screw member in one direction moves the handle portion in a direction in which the second member is removed from the first member.

[0019] In the engagement structure according to the fifth embodiment, the engagement can be released by rotating the screw member, whose screw head is exposed from the opening, in one direction, thereby moving the handle portion in a direction in which the second member is removed from the first member. [Effects of the Invention]

[0020] The engagement structure of this disclosure allows for easy disengagement without the use of special tools or thermal deformation, while suppressing accidental or unintentional disengagement from the outside. [Brief explanation of the drawing]

Modes for Carrying Out the Invention

[0022] Hereinafter, embodiments of the engagement structure according to the present disclosure will be described in detail with reference to the drawings. The engagement structure of the present disclosure can be used for joining various members and components, such as the attachment of exterior parts and interior parts of a vehicle, and the joining of housings of electronic devices.

[0023] [First Embodiment] FIG. 1 shows a cross-sectional view showing an engagement structure 10A according to the first embodiment of the present disclosure. The engagement structure 10A is a structure for joining a first member 20 and a second member 30.

[0024] The first member 20 is box-shaped and has a bottom plate 22 and a first side wall 24. The bottom plate 22 is square plate-shaped, and the first side wall 24 is erected from each outer peripheral edge of the bottom plate 22. A pair of engaged portions 26 are formed on the upper inner side walls (hereinafter referred to as "inner walls 24A") of the first side wall 24 that face each other. The engaged portion 26 is concave and inclined in a V-shape in the vertical direction, and an engaging portion 36 described later is engaged therewith.

[0025] The second member 30 is box-shaped, having the same outer shape as the first member 20 for the opening, and includes a lid plate 32 and a second side wall 34. The lid plate 32 is rectangular, and the second side wall 34 is erected downward from each outer periphery of the lid plate 32. The inner wall 34A of the second side wall 34 is positioned further inside the box than the inner wall 24A of the first side wall 24. A pair of engaging portions 36 are formed on the lower inner sides of the second side wall 34, which are opposite each other.

[0026] Each of the pair of engaging portions 36 protrudes downward from the lower end surface 34B of the second side wall 34 and has a base portion 36A and a protrusion portion 36B. The base portion 36A is positioned so that the inside of the box is flush with the inner wall 34A and the outside of the box is aligned with the inner wall 24A of the first side wall 24. The base portion 36A is thinner than the second side wall 34 and is elastically deformable. The protrusion portion 36B is formed continuously from the tip of the base portion 36A, so that the inside of the box is flush with the base portion 36A and the outside of the box protrudes outward so as to fit into the engaged portion 26. When the protrusion portion 36B fits into the engaged portion 26, the engaging portion 36 engages with the engaged portion 26 and the second member 30 is attached to the first member 20.

[0027] A handle portion 40 is connected to a pair of engaging portions 36. The handle portion 40 has a connecting portion 42 and a handle portion 44. The connecting portion 42 is provided to connect the pair of engaging portions 36, with one end connected to one engaging portion 36 and the other end connected to the other engaging portion 36. One end and the other end of the connecting portion 42 are connected to the boundary side (tip) of the base portion 36A with the protrusion 36B. The connecting portion 42 is elastically deformable.

[0028] The handle portion 44 has a connecting portion 44A that is erected from the central part of the connecting portion 42, and a disc-shaped gripping portion 44B provided at the upper end of the connecting portion 44A.

[0029] An access opening 32A is formed in the center of the cover plate 32. An opening / closing member 33 is positioned in the access opening 32A. The access opening 32A is closed by the opening / closing member 33. The access opening 32A is opened by removing the opening / closing member 33.

[0030] Next, the operation of this embodiment will be described.

[0031] When attaching the second member 30 to the first member 20, the second side wall 34 of the second member 30 is brought into contact with the first side wall 24 of the first member 20, and the protrusion 36B is engaged with the engaging portion 26. This attaches the second member 30 to the first member 20. In this state, the cover plate 32 and the second side wall 34 of the second member 30 cover the inner wall 24A of the first member 20, and an inner space R1 is formed between the first member 20 and the second member 30. The handle portion 40 (handle portion 44 and connecting portion 42) is located in the inner space R1.

[0032] To remove the second member 30 from the first member 20, the opening / closing member 33 is removed and the access opening 32A is opened, as shown in Figure 2. The handle portion 44 located in the inner space R1 is accessed from the access opening 32A, and the handle portion 44 is pulled in the direction in which the second member 30 is removed from the first member 20 (upwards in Figure 2). As a result, an inward-sloping upward force acts on each of the pair of engaging portions 36, causing the base portion 36A to elastically deform and move inward into the inner space R1, releasing the engagement between the convex portion 36B and the engaged portion 26, and allowing the second member 30 to be removed from the first member 20.

[0033] In the engagement structure 10A of this embodiment, by moving the handle portion 40 in the direction that the second member 30 is removed from the first member 20, a force is applied to the engagement portion 36 in the direction that disengages it from the engaged portion 26. Therefore, by moving the handle portion 40 in this direction, the engagement between the engagement portion 36 and the engaged portion 26 can be easily released, and the second member 30 can be removed from the first member 20.

[0034] Furthermore, in the engagement structure 10A of this embodiment, the handle portion 40 is positioned in the inner space R1 formed between the first member 20 and the second member 30, so that force is not unintentionally applied to the handle portion 40 and the engagement between the engaging portion 36 and the engaged portion 26 is suppressed.

[0035] Furthermore, in the engagement structure 10A of this embodiment, the pair of engagement parts 36 are provided in the central part of the handle part 40, facing each other with the handle part 40 in between. Therefore, the movement of the handle part 40 allows force to be applied to each engagement part 36 in a balanced manner.

[0036] Furthermore, in the engagement structure 10A of this embodiment, an access opening 32A is provided, allowing access to the handle portion 40 through the access opening 32A to operate the handle portion and release the engagement. In addition, since the opening / closing member 33 covers the access opening 32A, it is possible to more reliably prevent unintentional force from being applied to the handle portion 40.

[0037] [Second Embodiment] Next, a second embodiment of the present disclosure will be described. In this embodiment, the same reference numerals are used for parts that are the same as in the first embodiment, and their detailed descriptions are omitted.

[0038] The engagement structure 10B of this embodiment differs from the engagement structure 10A of the first embodiment in the shape of the handle portion. As shown in Figure 3, this embodiment is equipped with a handle portion 45 instead of the handle portion 40.

[0039] The handle portion 45 is connected to each of the pair of engaging portions 36. The handle portion 45 has a pair of connecting portions 46 and a handle portion 48. One end of each of the pair of connecting portions 46 is connected to the inner space R1 side of the protrusion 36B of the engaging portion 36. The pair of connecting portions 46 are inclined so that the other end approaches the cover plate 32. The other ends of the pair of connecting portions 46 are connected to both ends of the handle portion 48.

[0040] The handle portion 48 is provided between a pair of connecting portions 46 so as to connect them. The handle portion 48 and the pair of connecting portions 46 connect the pair of engaging portions 36.

[0041] Next, the operation of this embodiment will be described.

[0042] The second member 30 is attached to the first member 20 in the same manner as in the first embodiment. With the second member 30 attached to the first member 20, the handle portion 45 (handle portion 48 and connecting portion 46) is positioned in the inner space R1 between the first member 20 and the second member 30.

[0043] To remove the second member 30 from the first member 20, the opening / closing member 33 is removed and the access opening 32A is opened, as shown in Figure 4. The handle portion 48 located in the inner space R1 is accessed from the access opening 32A and the handle portion 48 is pulled in the direction in which the second member 30 is removed from the first member 20 (upwards in Figure 4). As a result, an inward and upward diagonal force acts on each of the pair of engaging portions 36, causing the base portion 36A to elastically deform and move inward into the inner space R1, releasing the engagement between the convex portion 36B and the engaged portion 26, and the second member 30 can be removed from the first member 20.

[0044] The engagement structure 10B of this embodiment can achieve the same effects as the engagement structure 10A of the first embodiment.

[0045] [Third Embodiment] Next, a third embodiment of the present disclosure will be described. In this embodiment, the same reference numerals are used for parts that are the same as in the first and second embodiments, and their detailed descriptions are omitted.

[0046] The engagement structure 10C of this embodiment differs from the engagement structure 10B of the second embodiment in the shape of the handle portion in the grip portion and the access opening 32A.

[0047] As shown in Figure 5, in the engagement structure 10C of this embodiment, the cover plate 32 has a screw support hole 32B instead of an access opening 32A. The screw support hole 32B is tapered, with a smaller diameter at the bottom.

[0048] In this embodiment, the engagement structure 10C has a screw hole 48A formed in the center of the handle portion 48. The screw hole 48A has an internal thread into which a screw member 50, which will be described later, is screwed.

[0049] The engagement structure 10C of this embodiment includes a screw member 50. The screw member 50 has a threaded portion 52 and a screw head 54. The threaded portion 52 has male threads and is screwed into the screw hole 48A. The screw head 54 is shaped to conform to the screw support hole 32B and is rotatably supported in the screw support hole 32B with its upper surface exposed to the outside.

[0050] Next, the operation of this embodiment will be described.

[0051] The second member 30 is attached to the first member 20 in the same manner as in the first embodiment. With the second member 30 attached to the first member 20, the handle portion 45 (handle portion 48 and connecting portion 46) and the threaded portion 52 of the screw member 50 are positioned in the inner space R1 between the first member 20 and the second member 30.

[0052] When removing the second member 30 from the first member 20, the screw member 50 is rotated in the direction in which the screw is tightened, as shown in Figure 6. As a result, the screw head 54 is supported by the screw support hole 32B, the screw portion 52 is screwed into the screw hole 48A, and the handle portion 48 moves toward the cover plate 32. This direction is the direction in which the second member 30 is removed from the first member 20 (upper part in Figure 6). This causes an inward-sloping upward force to act on each of the pair of engaging portions 36, releasing the engagement between the protrusion 36B and the engaged portion 26, and allowing the second member 30 to be removed from the first member 20.

[0053] In the engagement structure 10C of this embodiment, the engagement can be released by rotating the screw member 50 in one direction, thereby moving the handle portion 45 in a direction that removes the second member 30 from the first member 20.
