Abstract

<P>PROBLEM TO BE SOLVED: To provide a window opening/closing device which makes a window screen opened/closed by turning a foldable handle, which enables the handle to be folded to be inconspicuous from the outside, and which prevents the handle from being folded during a turning operation; and to provide a window using the window opening/closing device. <P>SOLUTION: The handle 4 is constituted in a horizontally long shape in such a manner as to be foldable in parallel along a device body 1 formed in a horizontally long shape. The handle 4 is foldably connected to a socket 5; and a base is provided with an engaging portion 21. The socket is attached to a rotating shaft 6; and an abutting portion 22 is formed around the rotating shaft so that the engaging portion can abut thereon when the handle in a rising stage is turned in a folding direction. In a position in which the handle is parallel to the device body, a nonabutting portion 23 is provided so that the abutting portion and the engaging portion can be disengaged from each other. During the turning of the handle, the handle cannot be folded because the engaging portion abuts on the abutting portion. In the position parallel to the device, since the engaging portion does not abut on the abutting portion, the handle can be folded. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a window opening / closing device that can open and close a window shoji attached to a window frame with a hanging metal fitting by a rotating operation of the handle, and more particularly to a window opening / closing device having a foldable handle.

  2. Description of the Related Art Conventionally, as a window shoji opening / closing device that is attached to a window frame with a hanging bracket so as to be freely opened and closed, a device that rotates a handle and opens and closes the window shoji through a driving mechanism is known (for example, see Patent Document 1). As such a window opening / closing device, the device described in Patent Document 1 using a worm gear mechanism has a device main body attached to an indoor window frame, a worm driven by a handle, and a worm. A wheel gear to be driven and a drive arm that is driven by the wheel gear to open and close the window shoji are provided. The rotating shaft of the worm is projected from the main body, and the socket of the folding handle is connected to the spline formed on the rotating shaft. Window shoji opens and closes through the arm. In this way, in the conventional device, the main body and the handle are designed separately, and even when the handle is folded, the handle protrudes greatly from the main body. Since it is clearly seen from the outside, it is not preferable from the viewpoint of crime prevention.

  Furthermore, the folding handle can be folded at any position during the rotation of the rotary shaft, so when rotating with the folded handle raised, if the handle is folded, it will bend easily. Rotating operation becomes difficult and the handle cannot be operated well. Therefore, various devices have been proposed that incorporate a folding prevention mechanism so that the handle is not easily folded during handle operation (see, for example, Patent Document 1 and Patent Document 2 above). However, if such a prevention mechanism is incorporated, the structure of the folding part becomes complicated, and it is not economically obtained, and the handle operation is troublesome. For example, in a device that automatically locks when the folding handle is raised and prevents folding, when the handle is folded after opening / closing the window, a push button or switching knob is used to release the locking mechanism. The handle cannot be folded without operating.

Japanese Patent No. 2929098 (Claims, FIGS. 2 to 24) Japanese Patent No. 4182275 (Claims and Drawings)

  The problem to be solved by the present invention is that, in the window opening and closing apparatus using the folding handle as described above, the handle does not protrude greatly from the main body in the folded state and is seen as being integrated with the main body, and when the handle is raised and rotated. It is another object of the present invention to provide a window opening / closing device which can operate a handle without any trouble without incorporating a lock mechanism such as a lock button for holding in an upright state.

  According to the present invention, in a window opening / closing device in which a handle pivotably attached to a socket is erected to rotate a rotating shaft to open / close a window shoji through a driving mechanism, the device main body is formed in a horizontally long shape. The handle is formed in a horizontally long shape so as to be accommodated in parallel with the apparatus main body in a folded state, and an engaging portion is provided at the base end, and the socket of the handle is a rotating shaft protruding from the apparatus main body. A contact portion is formed on the apparatus body around the rotation shaft so that the engagement portion contacts when the standing handle is rotated in the folding direction. A window opening / closing device is provided in which a non-contact portion is provided so that the engaging portion of the handle does not contact when located in a parallel position along the device main body, and the above problems are solved.

  Further, according to the present invention, the engaging portion is a substantially mountain-shaped protruding piece 21 (24) as shown in FIG. 7 or a hook-shaped engaging protruding piece 21 (31) as shown in FIG. The contact portion is formed on a flat surface or an annular protruding edge, the handle has a knob, a knob housing portion is formed in the apparatus body, and the drive mechanism includes a worm formed on the rotating shaft. The window opening / closing device including a wheel gear that engages with the worm and a drive arm that is rotated by the wheel gear is provided to solve the above-described problem.

  The present invention is configured as described above, and in the window opening and closing apparatus configured to open and close the window shoji through the drive mechanism by raising the handle pivotally attached to the socket so that it can be folded, the apparatus main body includes: The handle is formed in a horizontally long shape so that the handle is stored in parallel along the apparatus main body in a folded state, and an engagement portion is provided at the base end. Attached to the tip of the protruding rotating shaft, the device body around the rotating shaft is formed with an abutting portion so that the engaging portion abuts when the standing handle is rotated in the folding direction. A non-contact portion is provided to prevent the engagement portion of the handle from coming into contact with the handle when the handle is in a position parallel to the device main body. Can be folded Housed in the apparatus main body in a parallel state with wear, to unobtrusive, appearance may be, because seen integral with the apparatus body, crime prevention be seen from the outside it is safe.

  In addition, when the handle that has been raised is rotated when the window is opened and closed, the engaging portion abuts against the contact portion and the handle is maintained in an upright state even if the handle is rotated in the folding direction. Even if a force is applied in the direction of folding the handle, the handle is not likely to be folded and can be operated in a stable state. When the handle is rotated 360 degrees, it passes through a position parallel to the main body of the apparatus. However, since the handle rotates continuously, this position passes in an instant and is not accidentally folded. And, when the handle is not in use as described above, if the rotation of the handle is stopped at a position parallel to the apparatus main body, the engagement portion corresponds to the non-contact portion, so that the handle can be folded. Thus, the handle can be stored along the apparatus main body. Further, since a special locking mechanism for locking the standing state as in the prior art is unnecessary, it is economically obtained and easy to handle. Further, since the handle covers the socket in the folded state, the opening angle of the handle in the standing state can be increased, for example, 140 degrees, which is easy to use.

  1 to 6 showing an embodiment of the present invention, an apparatus main body 1 is formed in a horizontally long shape so as to be attached along a window frame, and a mechanical main body 2 containing a drive mechanism and a front surface of the mechanical main body are arranged. The drive mechanism shown in the embodiment is composed of a cover body 3 that covers the rotating shaft 6 to which the socket 5 of the handle 4 is connected, a worm 7 that is rotated by the rotating shaft, and a wheel gear that meshes with the worm and rotates. 8 and a drive arm 9 formed integrally with the wheel gear. The drive arm opens and closes a window shoji (not shown) attached to the window frame so as to be freely opened and closed with a hanging metal fitting. Further, a selection lever 10 is provided for controlling the rotation of the wheel gear to select the opening position of the window shoji as a fully open position or a half open position. In addition, drive mechanisms other than a rotating shaft can be made into an appropriate structure with the kind of window shoji, and its opening / closing structure.

  A spline 11 is formed on the rotating shaft 6, and a socket 5 of the handle 4 is fitted to the spline and fixed with a set screw 12. The handle 4 is formed in a horizontally long shape so as to be substantially parallel to the apparatus main body 1 in a folded state, and a socket accommodating portion 14 is provided inside the handle 4 so as to cover the socket 5 and the bracket 13 projecting from the side surface thereof. The bracket 13 and the side wall of the handle 4 are pivotally attached to the handle shaft 15 so as to be foldable, and a knob 16 is provided at the end.

  The cover body 3 of the apparatus main body 1 has a through-hole 17 through which the tip of the rotary shaft 6 is inserted, and a flat surface section for storing the folded handle so that it can be seen integrally with the apparatus main body. 18 is formed, and a knob housing part 19 for housing the knob 16 is formed adjacent to the flat surface part 18. The flat surface portion 18 and the knob storage portion 19 are formed in an appropriate shape according to the shape of the handle and the knob so that the handle 4 can be seen integrally with the apparatus main body 1 when the handle is folded. In order to easily raise the handle, an appropriate guide recess 20 is provided in the cover body 3 and the handle 4 so that a little fingertip can be inserted.

  An engaging portion 21 is formed at the proximal end of the handle 4 that extends from the handle shaft 15 toward the outer peripheral surface of the socket 5. On the other hand, the cover body 3 around the through-hole 17 of the rotating shaft 6 is formed with a contact portion 22 so that the engagement portion 21 contacts when the raised handle is rotated in the folding direction. ing. Therefore, when rotating the rotating shaft by rotating the handle in the standing state, the handle is prevented from moving in the folding direction and the handle is held in the standing position when the engaging portion is in sliding contact with the contact portion. The The abutting portion 22 is formed on substantially the entire circumference around the through hole 17, but the non-abutting portion prevents the engaging portion from abutting at a position where the handle 4 is substantially parallel to the apparatus main body 1. 23 is formed. Accordingly, at the position corresponding to the non-contact portion 23, the engagement portion 21 and the contact portion 22 of the handle 4 are disengaged, so that the handle 4 can be moved in the folding direction.

  The engaging portion, the abutting portion, the non-abutting portion, and the like can be configured in various forms. In the embodiment shown in FIG. 1 and the like, the engaging portion 21 has a substantially mountain shape in the proximal direction of the handle 4. The contact portion 22 is formed on a flat surface 25, and the non-contact portion 23 is formed on a recess portion 26 that allows the protrusion piece 24 to pass therethrough. With this configuration, when the handle is raised and rotated around the rotation axis, one side edge 27 of the mountain shape of the projecting piece 24 hits the inner surface between the brackets of the socket, and the handle is reduced as shown in FIG. It can be held at an opening angle of 140 degrees. In this state, even if the handle 4 is to be folded in the direction of the arrow 28, the other side edge 29 is in contact with the contact portion 22, and in particular, the tip end portion of the protruding piece 24 contacts the flat surface 25. Can not. Therefore, the handle 4 can be smoothly rotated around the rotation shaft 4. While the handle rotates, it passes through a position parallel to the main body of the apparatus, but since this position is an instant when the handle is rotated 360 degrees, there is very little risk of hindering the rotation operation.

  Further, when the handle 4 is folded, if the rotation of the handle is stopped at a position parallel to the apparatus main body, the protruding piece 24 corresponds to the recess 26 provided in the cover main body 3 as shown in FIG. Even if the handle 4 is rotated in the direction of the arrow 30, the tip end portion of the protruding piece does not hit the recessed portion 26 and can be folded without any trouble. In this folded state, the socket 5 enters the socket housing part 14 of the handle 4, and the handle 4 is housed in an almost integrated state with the apparatus main body 1 with the knob 16 entering the knob housing part 19, and is conspicuous from the outside. So that it does not protrude.

  FIG. 9 shows another embodiment of the engagement portion, the contact portion, and the non-contact portion. The engagement portion 21 is an engagement protrusion 31 formed in a hook shape, and the contact portion 22 is the engagement portion. An annular projecting edge 32 erected around the through hole 17 of the cover body 3 so that the projecting piece 31 is engaged, and the non-contact portion 23 is engaged with the engaging projecting piece 31 when the handle 4 is folded. It is a notch 33 formed in a part of the annular protruding edge 32 so that the alignment is removed. With this configuration, when the handle 4 is in the upright state, the engagement protrusion 31 and the annular protrusion 32 are engaged as shown by the solid line in FIG. Can be rotated. On the other hand, when the handle is positioned at a position parallel to the apparatus main body as shown in FIG. 9, the engagement protrusion 31 corresponds to the notch 33, so that the handle 4 can be folded in the direction of the arrow 35. Can be folded and stored along the main body.
