Description

  The present invention relates to a finger padding prevention tool for preventing finger padding when a rotating door is closed.

  A revolving door attached by a hinge or the like is openable and closable, and there is a risk of accidents if it is closed vigorously because there is a risk that a finger may be pinched on the hinge side or knob side when closed. As a device for preventing such finger filling, a door closer (door check) for gently opening and closing a door has been conventionally known.

  However, since the door closer needs to constitute a hydraulic mechanism, it is expensive and difficult to install for a door of a general household. Moreover, in order to make the function of the door closer function assured, regular adjustment is necessary, which is troublesome.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a finger padding prevention tool that can reliably prevent finger padding by a rotating door and that can be easily installed at low cost.

The object of the present invention is a finger padding prevention tool for preventing finger padding when the rotating door is closed, in order to suspend and support the buffer part made of an elastic body and the buffer part above the door. And a gripping part attached so as to hang down from the buffer part in a supported state, the buffer part has a through hole, and the support part is formed in the through hole. The gripping part is achieved by a finger padding prevention tool attached to the retaining piece .

In this finger padding prevention tool, the support portion is made of an elastically stretchable member, and the gripping portion is made of a string-like body that is inserted into an insertion ring provided in the retaining piece and formed in a loop shape. preferable. Moreover, it is preferable that the said buffer part is a spherical body.

  According to the present invention, it is possible to provide a finger padding prevention tool that can reliably prevent finger padding and that can be easily installed at low cost.

  Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing a finger padding prevention device according to an embodiment of the present invention.

  As shown in the figure, the finger padding prevention tool 1 includes a buffer portion 10, a support portion 20 that supports the buffer portion 10 in a suspended manner, and a grip portion 30 that hangs down from the supported buffer portion 10.

  The buffer part 10 is comprised from the spherical body which can be elastically deformed, such as foaming urethane and a synthetic rubber, and has the through-hole 12 penetrated so that it may pass through the center. The support portion 20 is made of an elongated elastically stretchable member such as a rubber string, and an attachment ring 22 for attaching the finger padding prevention device 1 to a wall surface or the like is provided on one end side. The other end side of the support portion 20 is inserted into the through hole 12 of the buffer portion 10 and attached to the disc-shaped retaining piece 14, and the buffer portion 10 is configured to be supported by the support portion 20. The retaining piece 14 has an insertion ring 141 through which a string-like body is inserted, and a loop-shaped grip 30 is formed by connecting ends of the string-like bodies inserted through the insertion ring 141. .

  As shown in FIG. 2, the finger padding prevention device 1 having the above configuration is supported above the door D by attaching a suction cup hook or the like to the upper wall surface of the door D and hooking the mounting ring 22 on the hook. The The mounting position of the mounting ring 22 is preferably set so that the center height of the buffer portion 10 substantially coincides with the upper edge of the door D as shown in the figure.

  As shown in FIG. 3 (a), the finger padding prevention device 1 supported in this way is released from a state in which the door is completely closed, and the buffer portion 10 is pulled by the support portion 20 as shown in FIG. Draw up along the surface of D. Then, with the door D opened to some extent, the buffer portion 10 gets over the upper edge of the door D and falls to the opposite side, resulting in the state shown in FIG. When the door D is closed in this state, as shown in FIG. 3C, the buffer portion 10 is sandwiched between the upper portion of the frame F and the upper edge portion of the door D, so that the door D is completely closed. There is no fear of being As a result, even when the door D is closed vigorously, it is possible to reliably prevent finger jamming while preventing the door D from being damaged or generating an impact sound due to the elastic deformation of the buffer portion 10. After the buffer part 10 gets over the door D, the position of the buffer part 10 is constant even if the door D is repeatedly opened and closed, and the gripping part 30 hangs down on the opposite side of the buffer part 10 across the door D.

  A gap generated between the door D and the frame F due to the interposition of the buffer portion 10 can be adjusted by moving the mounting position of the mounting ring 22 in the horizontal direction. That is, when the attachment position is moved to the hinge H side of the door D (in the direction of arrow A in FIG. 2), the side edge of the door D on the knob K side or the side edge of the hinge H side and the frame F when closed. While the gap formed therebetween increases, when the attachment position is moved to the knob K side of the door D (in the direction of arrow B in FIG. 2), the gap is reduced. Therefore, by setting the attachment position such that the door D is closed to the extent that no finger padding occurs, the finger padding prevention tool 1 can function effectively.

  When the door D is completely closed, the grip portion 30 is pulled down along the surface of the door D in the state shown in FIG. Thereby, since the buffer part 10 is pulled up and gets over the upper edge of the door D again (refer Fig.3 (a)), the door D can be closed as usual. Thus, even when it is necessary to completely close the door D, it is possible to cope without requiring a particularly complicated procedure. The attachment position of the grip portion 30 to the buffer portion 10 is preferably the lowermost end of the buffer portion 10 as in the present embodiment, which makes it easy to lift the buffer portion 10 and the procedure when the door D is completely closed. Can be done smoothly. In addition, the length of the grip portion 30 is set so as to hang down to a height position where a child's hand that may be finger-filled cannot reach in the state shown in FIG. 3B or 3C, for example. It is preferable.

  As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to the said embodiment. For example, in the present embodiment, the buffer portion 10 is formed in a spherical shape so that the buffer portion 10 can easily get over the upper edge of the door D, but various shapes such as a spheroid shape, a polyhedral shape, a cube shape, and a plate shape are used. It is also possible to make it.

  Moreover, in this embodiment, although the support part 20 is comprised with the rubber string, if it is a member which can support the buffer part 10 in a predetermined position, it will not specifically limit, Elastic elasticity is not necessarily required. However, when a member capable of elastic expansion and contraction is used for the support portion 20, the tensile force acting on the mounting ring 22 when the buffer portion 10 gets over the door D can be reduced by the support portion 20 extending. Therefore, there is no possibility that an excessive force acts on the attachment portion and the like, and the durability can be improved. Examples of other forms of the elastically extendable support 20 include rubber bands and coil springs.

  Further, in the present embodiment, the grip portion 30 is configured by binding the string-like body in a loop shape, but is not particularly limited as long as it is a grippable member that hangs down from the support portion 20, for example, A grip portion may be provided at the lower end of the grip portion 30 so that it can be easily gripped.

It is a front view which shows the finger padding prevention tool which concerns on one Embodiment of this invention. It is a front view which shows the attachment state of the finger padding prevention tool shown in FIG. It is a perspective view for demonstrating an effect | action of the finger padding prevention tool shown in FIG.
