Description

  The present invention relates to a futon scissors suitable for use in drying a futon.

  Conventionally, a pair of sandwiching arms that are pivotally attached to each other at one end and have a sandwiching portion for sandwiching a futon at the other end, and the pair of sandwiching arms are always attached in a closing direction. Futon scissors are known, which are composed of springs. The bedding part of the futon that is hooked in a folded manner on the handrail of the veranda is sandwiched from above using this futon scissors and fixed, so that the futon can be removed from the handrail when it is blown up by the wind. It can prevent falling.

By the way, in the futon scissors having such a structure, the sandwiching arm and the sandwiching portion of the distal end thereof are usually integrated (usually, the sandwiching portion is formed by bulging the distal end portion of the sandwiching arm inward. If the opening width of the clamping arm changes depending on the thickness of the futon to be clamped), the pressure contact angle of the clamping part to the surface of the futon changes, which makes the clamping force of the clamping part unstable. There was a problem.
If the clamping force by the clamping part is unstable, it becomes difficult to securely clamp the futon, and if the futon is blown by the wind, the futon scissors may come off the futon and the futon may fall off the veranda There is. In addition, if the sandwiching portion is pressed against the futon obliquely, the futon may be strongly pressed at the corners or the like, and the surface of the futon may be damaged.

  Also, when attaching the futon scissors to the futon, it is necessary to open both hands against both springs against the spring force of the spring, and to sandwich it in the folded part of the duvet. The attachment work is unexpectedly troublesome, especially in the futon scissors in which the spring force of the spring is strengthened in order to strengthen the holding force of the holding arm.

  The present invention was made in view of the problems of the conventional futon scissors. When drying the futon on the handrails of the veranda, the futon is surely not affected by the thickness of the futon. The purpose is to provide futon scissors that can be pinched.

  That is, in the device according to the first aspect, the other end portions of the pair of sandwiching arms provided with the sandwiching portion at one end are rotatably connected via the support shaft, and the pair of sandwiching arms are biasing means. In the futon scissors that are normally biased in the closing direction, the clamping portion is provided so as to be swingable in the rotation direction of the clamping arm.

  The invention described in claim 2 is characterized in that, in the futon scissors according to claim 1, irregularities are formed on a surface of the sandwiching arm that presses against the futon.

  The invention described in claim 3 is the futon scissor according to any one of claims 1 and 2, wherein the pair of sandwiching arms are open-side end portions of the pair of sandwiching arms. A grip portion for opening the holding arm is provided on the outside.

  According to the first aspect of the present invention, since the sandwiching portion is swingable in the rotational direction of the sandwiching arm, the sandwiching portion is always parallel to the surface of the comforter without being affected by the thickness of the comforter. It can be press-contacted, and thereby, the futon can be clamped reliably and efficiently.

  Further, according to the invention described in claim 2, since the unevenness is formed on the surface of the sandwiching portion pressed against the comforter, the unevenness bites into the surface of the comforter during the pressing, so that the comforter becomes less slippery. It can be pinched more reliably.

  According to the invention described in claim 3, since the gripping portion is provided at the opening side end of the holding arm, the opening operation of the holding arm can be performed without requiring a large force, and the futon drying The installation work of the futon scissors at the time becomes easy. In addition, since the clamping part which clamps the futon is located inside the gripping part, the hand holding the gripping part does not get in the way when attaching the futon scissors.

  Hereinafter, embodiments of the futon scissors according to the present invention will be described with reference to FIGS.

  1 and 2, reference numeral 1 denotes a pair of sandwiching arms formed of a resin frame having a U-shaped cross section. The pair of sandwiching arms 1 and 1 have a curved shape for suitably sandwiching the futon, and are connected to each other via a support shaft 2 so as to be rotatable at one end. A coil spring 7 as an urging means is disposed around the support shaft 2, and each end of the coil spring 7 is brought into contact with the corresponding inner wall of the holding arm 1, so that the coil spring 7 The pair of sandwiching arms 1 and 1 is constantly biased by the spring force.

In addition, a grip portion 4 for opening the sandwich arms 1 and 1 is provided at the opening side end portions of the pair of sandwich arms 1 and 1, and the grip portion 4 is provided with a handle for easy gripping. It is made with shape.
Further, a U-shaped support portion 9 having a pair of side walls 9c opposed to each other toward the inner side of the grip portion 4 is provided, and sandwiching a futon between the side walls 9c of the support portion 9 is provided. The part 3 is connected so as to be swingable in the rotating direction of the holding arm 1. That is, the pinching portion 3 is provided with a shaft 6 at the longitudinal center of the side portion, and the shaft 6 is rotatably connected to a shaft hole 8 provided in the side wall 9c of the support portion 9. The portion 3 is swingable about the shaft 6 as a fulcrum.

  As shown in FIGS. 3 and 4, the clockwise rotation (A) width of the clamping unit 3 is restricted by the back surface 3 b of the clamping unit 3 coming into contact with the lower edge 9 b of the support unit 9. The rotation (B) width of the clamping part 3 in the counterclockwise direction is configured to be regulated by the back surface 3b of the clamping part 3 coming into contact with the upper end of the bottom part 9a of the support part 9. As shown in FIG. 4, the rotation width (B) in the counterclockwise direction is larger than the rotation (A) in the clockwise direction so that the thick futon 20 can be securely held as will be described later. It is to make it.

  The sandwiching portion 3 is a rectangular body with rounded corners, the back surface 3b side is curved in a convex shape, and the opposite pressure contact surface 3a has a flat surface in a lateral direction (a direction perpendicular to the rotation direction). A plurality of wavy irregularities 5 extending in parallel to each other. In addition, these irregularities 5 are also rounded at the respective edges so that the damage given to the futon 20 when the clamping portion 3 clamps the futon 20 can be minimized.

When the futon is dried using the futon scissors according to the present embodiment, as shown in FIG. 5, the duvet 20 is hooked in a folded state on the clothes-drying member 30 (for example, a handrail 30 such as a veranda), The pair of sandwiching arms 1 and 1 are gripped from above by sandwiching the pair of sandwiching arms 1 and 1 against the spring force of the coil spring 7 and opening with both hands.
The gripping part 4 is located at the opening side end of the sandwiching arm 1, and does not require much force for the opening operation of the sandwiching arm 1 due to the action of the lever with the support shaft 2 at the opposite end as a fulcrum, and Since the holding part 3 that holds the futon 20 is positioned inside the holding part 4 held by both hands, both hands holding the holding part 4 do not get in the way when the futon scissors are held between the futons 20.

The pair of sandwiching arms 1, 1 are formed in a curved shape so as to favorably sandwich the futon 20, and the pressing surface 3 a of the sandwiching portion 3 is pressed against both sides of the duvet 20 by the urging force in the closing direction by the coil spring 7. The futon 20 is held so as not to fall from the clothesline member 30.
At this time, since the sandwiching portion 3 is swingable in the rotational direction of the sandwiching arms 1 and 1, even if the opening width of the sandwiching arms 1 and 1 changes depending on the thickness of the bent portion of the futon 20, the opening width is changed to the opening width. Accordingly, since the clamping part 3 freely swings, the pressure contact surface 3a of the clamping part 3 can always be pressed in parallel with the surface of the futon 20, and the entire surface of the pressure contact surface 3a can be pressed uniformly. That is, as the thickness of the bent portion of the futon 20 increases, the opening width of the sandwiching arms 1 and 1 increases, but with this, the sandwiching portion 3 rotates greatly in the counterclockwise direction (B). 3 pressure contact surfaces 3 a are always pressed in parallel with the surface of the futon 20. Therefore, even with a thick futon, the futon 20 can be securely clamped and fixed to the clothes drying member 30.

  Further, when the futon 20 is blown by the wind, an inadvertent pressing force (pressure contact force) on the futon 20 generated by the sandwiching portion 3 is greatly absorbed and relaxed by making the sandwiching portion 3 swingable. Therefore, as in the case of a futon scissor having a pinching part 3 integrated with the pinching arm 1, the inconvenience that the futon 20 is strongly squeezed at its corners or the like and the surface of the futon 20 is damaged is avoided. be able to.

  Further, since a plurality of irregularities 5 are formed in the lateral direction on the pressure contact surface 3 a of the clamping part 3, when the clamping part 3 is pressed against the futon 20, the irregularities 5 of the pressure contact surface 3 a bite into the surface of the futon 20. The futon 20 becomes difficult to slip, and the futon 20 can be more reliably clamped.

  As described above, in the present embodiment, the futon sheath is provided with the coil spring 7 around the support shaft 2 that rotatably connects the sandwiching arms 1 and 1 as biasing means for applying a closing force to the pair of sandwiching arms 1 and 1. However, the present invention is not limited to this, and although not shown in the drawings, a closing force is applied by providing a tension spring in a portion close to the rotation base end of the sandwiching arms 1 and 1 and connecting both the sandwiching arms 1. Of course, it can also be applied to the futon scissors.
