no. 1 Embodiment approach

[0033] Next, a first embodiment of the present invention will be described in detail.

[0034] FIG. 1 is a front view showing the cushion clip, and a cross-sectional view from the right side of the axis L. As shown in FIG. FIG. 2 is a side view showing the buffer clip, FIG. 3 is a plan view showing the buffer clip, and FIG. 4 is a bottom view showing the buffer clip. Fig. 5 is a front view showing a state in which the buffer clip is attached to the fixing member. The cushion clip 1 of the present embodiment is a member for absorbing impact force accompanying opening and closing of a lid of a storage box provided in front of a passenger seat of an automobile. The buffer clip 1 is roughly divided into a buffer portion 10 formed of a soft material such as an elastomer resin, and a mounting portion 20 formed of a hard material such as polypropylene (PP). In this specification, when viewing the buffer clip 1 as a whole, the side where the buffer portion 10 is disposed is defined ...

Embodiment

[0055] After a load is applied to the buffer portion of the buffer clip for a predetermined time and at a predetermined temperature, a comparative test is performed on the shape recovery characteristics of the buffer portion after the load is removed.

[0056] First, the buffer portion 110 of the conventional buffer clip 100 was fixed by a jig in a state compressed by 4 mm in the height direction (the height dimension of the buffer portion 110 before compression was 10 mm). Put this buffer clip 100 into the constant temperature tank, raise the temperature of the constant temperature tank from 23°C to 85°C over 1 hour, and keep the temperature at 85°C for 5 hours, then let the temperature of the constant temperature tank rise from 85°C to 85°C over 1 hour. down to 23°C. After repeating such a temperature change cycle twice, the buffer clip 100 was taken out from the constant temperature bath, released from the clip, and the height dimension of the buffer portion 110 was determi...

no. 2 Embodiment approach

[0060] Hereinafter, the second embodiment will be described in detail.

[0061] (1) A buffer clip that blocks the movement of a movable member approaching a fixed member by the vicinity of its end, and is provided with a buffer portion that absorbs an impact force, and a locking portion that is coupled to the fixed member, A hollow portion is formed in the buffer portion.

[0062] (2) The buffer clip according to (1) above, wherein the hollow portion is set in the vicinity of the substantially center of the buffer portion on an axis connecting a portion that receives an impact force on the buffer portion and the above-mentioned locking portion. A shape that passes through in the perpendicular direction.

[0063] (3) The buffer clip according to (2) above, wherein a convex portion is provided inside the hollow portion in a direction along the axis.

[0064] (4) The buffer clip according to (1) above, wherein the hollow portion is formed near a substantially center of the buff...

Abstract

A shock-absorbing clip (1) for receiving movement of a movable member (40) that approaches a fixation member (30), the shock-absorbing clip (1) having a shock-absorbing section (10) for absorbing impact force and an installation section (20) for installing the shock-absorbing section (10) to the fixation member (30). The shock-absorbing section (10) is made from an elastic soft material, and the installation section (20) is made from a hard material with predetermined rigidity. The shock-absorbing section (10) has a cavity (14) whose inner wall (18a) is substantially orthogonal to the fixation member (30) and the top section (12a) on the top side of the shock-absorbing section (10) is bent inward.

Description

technical field [0001] The present invention relates to a cushioning clip which absorbs impact force by blocking the movement of movable parts such as various opening and closing parts of a car near the end thereof. Background technique [0002] Conventionally, as such a clip, for example, a buffer clip disclosed in JP-A-2003-202043 is known. The buffer clip includes a buffer portion for blocking the movement of the movable member approaching the fixed member through the vicinity of its end, and a mounting portion for attaching the buffer portion to a predetermined position of the fixed member. The cushioning part is a member for absorbing the elastic deformation caused by blocking the movement of the movable member and absorbing the impact force at that time, so it is formed of a suitable soft material (rubber or elastomeric resin, etc.). Since the attachment portion is composed of a clip or the like elastically locked to the fixing member, it is formed of a suitable hard ...
