Description

  The present invention relates to a handwheel handle mechanism which is provided at an end portion of an apparatus having a lifting screw, rotates the lifting screw and is stored in a safe form when not in use so as not to get in the way.

  There are various types of devices having lifting screws. Among these existing technologies, a known technology similar to the present invention cannot be found by a search by the applicant, but one known technology is “Patent Document 1”.

JP2008-6985 (FIG. 1) The “handwheel handle of an electric switch” disclosed in “Japanese Patent Application Laid-Open No. 2008-6985” of “Patent Document 1” has a portion similar to the present invention in the structure of the crank handle (1). This function is used not for turning the lifting screw but for rotating the detent (3). Further, there is no storage structure when the crank handle (1) is not used, and the safety is greatly different from the present invention.

  There is a hand-operated handle as described in the above-mentioned "Patent Document 1", but generally a hand-operated handle is one in which a lifting screw or the like is operated by hand, and its structure is easy to hand-operate. However, the handwheel is convenient at the time of use, but when not in use, it is often a hindrance if left as it is, and there is a problem if it is left as it is for safety. Therefore, if possible, it is desirable that it can be conveniently rotated during use, and can be easily and safely stored when not in use.

  The present invention has been devised in view of the above circumstances, and an object thereof is to provide a handwheel mechanism that can be easily rotated when used and can be easily and securely stored in a safe position when not in use.

  In order to achieve the above object, the present invention provides a handwheel handle mechanism for operating a lifting screw provided in a lift section of the apparatus, the handwheel handle mechanism being a part of the apparatus. A handle detent storage member inserted into the upper part of the lifting screw and fixed to the fixed side of the device, and fixed at one end to the upper part of the lifting screw and extended toward the other end, and the handle at the extended position A handle rotating part that forms a long hole that can be accommodated in the gripping part; and a base end side of the handle gripping part that is fixed to an extended end of the handle rotating part and is rotatably supported. A handle gripping portion rotation support portion that forms a stopper portion that holds the rotation of the handle gripping portion in a state of being accommodated in a long hole of the handle rotation portion, and a proximal end side of the handle gripping portion rotation support portion Pin supported The handle holding part for enclosing the holding bar body other than the pin support part and rotating the handle rotation part in a shape that can be accommodated in the elongated hole of the handle rotation part, A spring body for spring-supporting the support rod body is provided in the handle gripping portion, and an end surface portion that presses against the stopper portion of the handle gripping portion rotation support when the handle support portion rotates is formed. The handle detent housing member is formed with a recess into which a front end side of the handle gripping portion housed in the elongated hole is fitted.

  According to the handwheel mechanism of claim 1 of the present invention, when the lifting screw is operated, the lifting handle is smoothly moved by lifting the gripping portion of the handle gripping part slightly against the spring body and rotating the handle rotating portion. It can be rotated. On the other hand, when the handle is not in use, the handle gripping portion is placed in a free state and is pushed down 90 degrees so that the handle gripping portion is housed in the long hole of the handle rotation portion and the handle gripping portion is attached to the stopper portion of the handle gripping portion rotation support portion. The handle gripping part is fitted into the recess of the handle detent storage member, and the handle gripping part is stably supported while being pushed down and stored in a safe state without being disturbed. You can increase the effect.

  Hereinafter, embodiments of the handwheel handle mechanism of the present invention will be described in detail with reference to the drawings.

  The handwheel handle mechanism of the present invention is used as an operating member of a lifting screw in various states, and as an example, it is applied to the apparatus shown in FIG. This device is formed so that a person who is physically handicapped but can walk by himself can safely sit on this device from the bed and move to the target place by himself. The seat plate 12 is provided on the upper plate 13 of the apparatus so as to move up and down in accordance with the height.

  An embodiment of the handwheel handle mechanism 100 of the present invention will be described below with reference to FIG.

  As shown in FIG. 1, the handwheel mechanism 100 of the present invention is fixed to the upper plate 13 of the apparatus and is inserted into and held on the upper part of the lifting screw (not shown). One end side is inserted into the upper part and the handle pivoting part 2 extending in the lateral direction, the handle gripping part pivoting support part 3 fitted to the other end of the handle pivoting part 2, and the handle gripping part pivoting support part 3 It is comprised from the handle | steering-wheel holding part 4 etc. which are pin-supported movably. Hereinafter, these structures will be sequentially described.

  As shown in FIGS. 1 to 4, the handle detent storage member 1 is a block-shaped member fixed to the upper plate 13 of the apparatus shown in FIG. 5, and is inserted into the upper part of the lifting screw (not shown) as described above. A concave portion 5 into which the tip end of the handle gripping portion 4 is fitted is formed on the upper surface side thereof, which is fixed on the upper plate 13.

  The handle rotation part 2 is composed of a rotation member that is fitted with one end on the upper part of a lifting screw (not shown), extends laterally, and is stepped on the other end. The handle part is accommodated in the intermediate part. The long hole 6 to be obtained is formed.

  The handle gripping portion rotation support portion 3 is formed of a cylindrical member that is fitted to the other end side of the handle rotation portion 2, and a stopper portion 7 that presses the end surface portion 11 of the handle gripping portion 4 is formed at one end portion thereof. Yes.

  The handle gripping portion 4 includes a support rod body 8 that is pin-supported at the lower end side by the handle gripping portion rotation support portion 3 and a gripping portion 9 that encloses a portion other than the pin support portion of the support rod body 8. The rod body 8 is spring-supported by a spring body 10 provided in the grip portion 9. In addition, an end surface portion 11 is formed at the lower end of the grip portion 9 so as to be in pressure contact with the stopper portion 7 of the handle grip portion rotation support portion 3 during rotation.

  The operation of the handwheel handle mechanism 100 having the above structure will be described below. When the lifting plate (not shown) is rotated to move the seat plate 12 (FIG. 5) up and down, as shown in FIGS. 1 and 2, the handle gripping portion 4 is gripped and the handle rotating portion 2 is rotated. Smooth rotation is possible.

  On the other hand, when not in use, as shown in FIGS. 3 and 4, the handle gripping portion 4 is rotated 90 degrees and pushed down, and stored in the oblong hole 6 of the handle rotating portion 2 so that it is not disturbed. I can do it. In this case, the end surface portion 11 of the grip portion 9 of the handle grip portion 4 is in pressure contact with the stopper portion 7 of the handle grip portion rotation support portion 3 and is stably inserted and pushed down into the recess portion 5 of the handle detent storage member 1. Retained.

  As described above, the handwheel handle mechanism 100 according to the present invention can smoothly rotate the lifting screw and can be housed in an unobstructed state when not in use to improve safety.

  The handwheel mechanism 100 of the present invention has the contents described above. However, the contents are not limited to the above description, and those of the same technical category are of course applied.

  The handwheel handle mechanism 100 of the present invention can be applied to all devices having a lifting screw, and its usage range is extremely wide.
