Description

  The present invention relates to scissors, and more particularly to a universal design scissors that can be used by people with reduced mobility.

  Traditionally, scissors have to operate the blade while repeatedly grasping the handle with a finger to cut the object to be cut, so scissors are used by people with reduced mobility, such as the elderly and muscular dystrophy patients. could not. As aging progresses steadily, an increasing number of handicapped elderly people are expected.

Under such circumstances, in recent years, universal design products that are kind to the elderly and the disabled are universally provided. There is also a universal design product for scissors. A protective cover in the form of a bag that covers both scissors blades is formed at the pivot and the vicinity of the pivot, and is attached in combination with the scissors. There is a proposal for a scissor with a protective cover having a gap portion provided with an insertable gap (see Patent Document 1).
JP 2004-154206 A

  However, the scissors described above have improved safety by enabling the cutting of the object to be cut with the protective cover attached to the blade body, and are not designed to be used by people with reduced mobility. Absent. Thus, conventionally, there has been no proposal for scissors that can be used by a handicapped person, and such scissors have been desired.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a universal design scissor that can be used by a handicapped person in order to cope with the arrival of an aging society.

  The invention for solving the above problems includes two blade bodies, a handle portion to which the base end of each blade body is attached, and a shaft portion that pivotally supports the two blade bodies. The handle portion is formed in an approximately annular shape from an elastic material, and a guide projection is provided on one side of the handle portion, and is supported by the blade body and the handle portion so that it can stand in the length direction. The main feature is scissors.

  With the above configuration, the scissors do not require any movement of gripping the handle by the user, and can advance the object to be cut, and can be used by people with limited hands. Here, the handicapped person refers to a person who cannot operate the blade body by holding the handle of the scissors with a finger, such as a person who does not have enough power in his hand or a person who cannot move his finger sufficiently due to paralysis. Can be exemplified by people with cervical spinal cord injury or stroke who cannot afford freedom of hand, those who have extremely weak grip, and patients with muscular dystrophy.

  In the above invention, a locking means for maintaining the blade body in a closed state may be provided. This allows scissors to be stored more safely when not in use.

  In each of the above-described inventions, the handle portion having a substantially annular shape includes a thick first half portion and a thin second half portion, and the width of the handle portion may gradually increase from the front to the rear. As a result, the front half of the handle portion of the scissors that stand up on the desk can be elastically applied to the handle portion in the latter half without unnecessarily bending. Can tell.

  The scissors of the present invention are universal design scissors and do not require an operation of gripping the handle, so that they can also be used by elderly people with disabilities and disabled people. Moreover, since various work including the hobby which uses scissors is attained, it becomes a big gospel for the handicapped elderly person who is expected to increase by aging.

  Hereinafter, the present invention will be described by way of embodiments with reference to the drawings.

  Each of the two stainless steel blades 1, 1 has a base end embedded and attached to the handle 10. Further, the two blade bodies 1 and 1 are pivotally supported by a shaft portion 5 made of synthetic resin.

  The handle 10 is formed in a substantially annular shape from a synthetic resin. Moreover, the handle | pattern part 10 is comprised from the front half part 11 formed thickly with a synthetic resin, as shown in FIG. 1, and the latter half part 12 formed thinly, and as shown in FIG. The width dimension is configured to gradually increase from the front to the rear.

  A flat stopper piece 15 that protrudes rearward is formed below the front half 11. A locking member 20 is formed above the front half 11. As shown in FIG. 3, the locking member 20 includes a pair of support pieces 21, 21, an operation rod 22 that protrudes outward from the support pieces 21, 21, and a lock rod 23 between the support pieces 21, 21. It is comprised and is formed with the synthetic resin. Further, the locking member 20 is rotatably attached to the handle portion 10 by means of attachment protrusions 24 formed on the upper portions of the support pieces 21 and 21. Since the scissors 50 of the present invention are usually in a state where the two blade bodies 1 and 1 are open, and it is safer to keep the blade bodies 1 and 1 closed during storage and carrying, The blades 1 and 1 as shown in FIG. 4 can be closed using the locking member 20. That is, by pressing down the operating rod 22 while the handle 10 is pressed, the locking rod 23 is locked at the protruding portion of the stopper piece 15 so that the blade bodies 1 and 1 can be kept closed. . When the normal blades 1 and 1 are in the open state, the fitting protrusions 26 formed on the support pieces 21 and 21 are fitted into the fitting recesses 25 formed on the handle 10 shown in FIG. Since the locking member 20 is fixed, it does not interfere with the push-down operation of the handle 10 at the time of cutting.

  Further, a guide protrusion 30 protrudes above the front half 11. The guide protrusion 30 is formed so as to be curved so as to have a width that allows a palm to be inserted between the guide protrusion 30 and the handle 10.

  Since the rear half 12 is formed thin, elasticity can be imparted to the handle 10. In addition, a reinforcing rib 13 is formed on the rear inner side of the rear half portion 12 in order to prevent weakening of the handle portion 10 due to bending of the rear half portion 12.

  Next, an operation method and its operation when a handicapped person uses the scissors 50 configured as described above will be described. As shown in FIG. 5, four fingers or palms other than the thumb are inserted from the lateral direction between the guide projection 30 of the scissors 50 erected in the length direction on a desk or the like and the handle portion 10, and the thumb is guided by the guide projection. Attach to the outside of 30. Then, the scissors 50 are moved while pushing the guide protrusions 30 forward, and an object to be cut such as paper is put between the two blade bodies 1. Next, the object to be cut can be cut forward by moving the guide protrusion 30 forward while repeatedly pressing the handle 10 with a finger or palm inserted between the guide protrusion 30 and the handle 10. The scissors 50 are supported by the tips of the blades 1, 1 and the boundary portions of the front half part 11 and the rear half part 12 so that they can stand in the length direction. The portion 11 does not bend unnecessarily and can stably stand up, and the latter portion 12 can impart sufficient elasticity to the handle portion 10. Moreover, since the width dimension of the handle | steering-piece part 10 is comprised so that it may become wide gradually toward the back from the front, the pressing force of the wide back can be reliably transmitted to the narrow front, and the cutting property of scissors is improved. be able to. In this way, the object to be cut can be cut simply by repeatedly pressing the handle 10 with a finger or palm, and the thumb can be attached to the outside of the guide projection 30, so that the scissors can be easily guided in a desired direction. This eliminates the need for a gripping operation and enables use by people with reduced mobility.

  Further, as shown in FIG. 6, the object to be cut may be cut while the guide protrusion 30 is sandwiched between fingers placed in parallel with the scissors 50 on the scissors 50 and the handle portion 10 is repeatedly pressed. Further, as shown in FIG. 7, the object to be cut may be cut while the guide protrusion 3 is pressed with a hand placed on the scissors 50 in parallel with the scissors 50 and the handle 10 is repeatedly pressed.

  In each of the above operation methods, when a person who can act to sandwich the object to be cut is used, the object to be cut may be moved while moving the object between the blades 1 and 1 without moving the scissors 50. . In particular, in the operation mode shown in FIGS. 5 and 6, since the scissors 50 are easily maintained stably so as not to fall down, the scissors 50 may be erected on the abdomen, thighs, or the like to cut the object to be cut. .

  The scissors 50 of the present invention can also be used by people who are not handicapped. In this case, although not shown, the object to be cut can be cut by repeatedly holding the handle 10 with a thumb inserted between the guide protrusion 30 and the handle 10 and a finger other than the thumb.

  The handle 10 can be manufactured by integral molding except for the locking member 20.

Since the present invention can be implemented with various modifications as long as it belongs to the technical scope, it will be exemplified below.
(1) The blade body is not limited to stainless steel, and may be formed of other metals, ceramics, or the like.
(2) The elastic material is not particularly limited as long as it has elasticity, and various synthetic resins and metals can be used.
