Description

[Technical Field]

[0001] The present invention relates to a retractable handle for opening and closing a window. [Background technology]

[0002] The operator device 50 for opening and closing a window W shown in Figure 5 comprises a base 51 that rotates integrally with its input shaft 50a, an arm 52 that extends radially from the base 51 and rises and falls, and a knob 53 located at the tip of the arm 52 that rotates relative to the base 51 and the arm 52, and is equipped with a retractable handle that assumes an operating mode when the arm 52 is raised and a retracted mode when the arm 52 is lowered.

[0003] As an example of a retractable handle with such a function, the following Patent Document 1 describes one that is composed of a four-bar link mechanism, and when the arm is raised during operation, the knob faces the operator, and when the arm is lowered during storage, the knob is aligned with the surface of the operator device.

[0004] Furthermore, the following Patent Document 2 describes a retractable handle that, when operating to open or close a window, holds an arm in an upright position by the pressure resistance of a leaf spring, and further restrains the leaf spring with a locking piece, thereby more reliably holding the arm in an upright position. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 7172877 [Patent Document 2] Patent No. 2929098 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with a retractable handle such as that disclosed in Patent Document 1, when the arm is raised from the retracted position to the operating position and then rotated continuously to open or close the window, the arm may be unintentionally released from its fixed position and fall over, which means that the arm must be raised again, which is time-consuming.

[0007] Furthermore, with the retractable handle disclosed in Patent Document 2, the locking piece that securely holds the arm in an upright position is difficult to see, which poses the problem of poor operability when switching between holding and releasing the arm in an upright position.

[0008] Therefore, an object of the present invention is to provide a retractable handle that can be easily converted from a retracted state to an operating state, can be reliably fixed in an upright state during a rotation operation for opening or closing a window, and can easily be switched between fixed and released in the upright state. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides a window opening / closing operator device comprising: a base that rotates integrally with an input shaft of the window opening / closing operator device; an arm that rises and falls relative to the base; and a knob located on the tip side of the arm, A retractable handle that is in an operating mode when the arm is raised and in a retractable mode when the arm is lowered, the arm has a crank portion connected to the base, and rises and falls by twisting relative to the base about a rotation center axis set on a plane inclined with respect to an extension direction of the crank portion, The object is to provide a retractable handle characterized by including a switch that prevents / allows twisting of the arm relative to the base.

[0010] The base is shaped so that an arm receiving portion is provided on the outer periphery of a base portion coupled to the input shaft of the operator device, the arm receiving portion protruding in a direction intersecting with the axis of the base portion, The arm receiving portion of the base and the crank portion of the arm are joined together so as to be rotatable, with their inclined end surfaces butting against each other, As the arm twists, the inclined end surface of the arm slides against the inclined end surface of the arm receiving portion, causing the arm to rise and fall.

[0011] Furthermore, the arm can be switched between a completely upright position and a completely reclined position relative to the base, allowing or preventing twisting.

[0012] The switch is provided on the arm and serves as an operating member for a stopper that engages with and disengages from a recess in the base, When the stopper engages with the recess, twisting of the arm is prevented, and when the stopper disengages from the recess, twisting of the arm is permitted.

[0013] Furthermore, the switch and the stopper are biased in a direction to fit into the recess of the base, When raising or lowering the arm, the switch is operated against the biasing force so that the stopper disengages from the recess, and when the arm is fully raised or lowered by twisting, the stopper automatically fits into the recess due to the biasing force.

[0014] The arm has a crank portion connected to the base and a knob connection portion to which the knob is rotatably connected. [Effects of the Invention]

[0015] In the retractable handle of this invention, if the switch is operated to allow the arm to twist, the arm can be easily raised and lowered simply by twisting it around the axis of its crank portion relative to the base, so that the arm can be quickly raised from its collapsed storage state to its operating state.

[0016] During the rotation of the arm to open or close the window, the switch prevents the arm from falling down, so the arm is reliably fixed in an upright position, and the arm can be rotated continuously in a stable operating mode to open or close the window.

[0017] Furthermore, the arm can be switched from an upright operating configuration to a collapsed storage configuration with a simple operation, and in the storage configuration, the arm and knob can be aligned with the operator device, giving it a smart appearance.

DETAILED DESCRIPTION OF THE INVENTION

[0019] <Configuration of the embodiment> (Summary of overall configuration) 1 to 3, this retractable handle H is used to open and close vertical sliding windows and the like, and is mainly composed of a base 1 that rotates integrally with the input shaft 50a of the operator device 50, an arm 2 that extends radially from the base 1 and rises and falls, and a knob 3 located at the tip of the arm 2. The arm 2 is provided with a semi-annular switch 4 that switches whether the arm 2 can be raised or lowered.

[0020] (Components and functions) The base 1 has a shape in which an arm receiving portion 12 is provided on the outer periphery of a cylindrical base 11 that is coupled to the input shaft 50a of the operator device 50. The arm receiving portion 12 protrudes in a direction that intersects with the axis of the base 11. A fixing screw 13 is screwed into the outer periphery of the base 11, thereby fixing the base 1 to the input shaft 50a of the operator device 50. The arm receiving portion 12 has an inclined end surface 12a that approaches the base 11 as it moves away from the operator device 50.

[0021] Arm 2 has a shape in which a short, round rod-shaped knob connection part 22 is connected to the tip of a long, round rod-shaped crank part 21 via a bent part. An inclined end face 21a corresponding to the inclined end face 12a of arm receiving part 12 of base 1 is formed on the base side of crank part 21, and a convex shaft 22a protrudes from the tip of knob connection part 22. The cross-sectional shapes of crank part 21 and knob connection part 22 are slightly flattened circular so as not to be bulky when stored.

[0022] Furthermore, by forming the cross-sectional shape of crank portion 21 into a flattened circle, it is possible to make inclined end surfaces 12a, 21a closer to a perfect circle. This makes it possible to eliminate the strange appearance caused by the inclined end surfaces 12a, 21a being misaligned with each other when arm 2 is in an intermediate position between the operation form and the storage form, and it is possible to prevent switch 4 from interfering with the outer circumferential surface of arm receiving portion 12 when arm 2 is in an intermediate position between the operation form and the storage form, as will be described later, and to prevent unintentional blocking of twisting of arm 2 when arm 2 is in an intermediate position between the operation form and the storage form.

[0023] The knob 3 is a short cylinder with an axial hole opening at the base end surface, and the convex shaft 22a of the knob connection part 22 is inserted into the axial hole via the knob base 31 (see Figure 4), and is rotatably connected to the arm 2.

[0024] The arm receiving portion 12 of the base 1 and the crank portion 21 of the arm 2 are butted against each other at inclined end faces 12a, 21a that are inclined relative to their respective axes, and are rotatably joined by a connecting screw 5 via a washer 6. When the arm 2 is twisted relative to the base 1 around a rotation central axis 21b that passes through the center of the inclined end face 21a of the crank portion 21 and faces in the normal direction thereof, the inclined end face 21a of the crank portion 21 slides against the inclined end face 12a of the arm receiving portion 12, causing the arm 2 to rise and fall.

[0025] Accordingly, as shown in Figure 2, when opening or closing the window W, if the arm 2 is raised, the axis of the convex shaft 22a, which is the rotation center of the knob 3, becomes parallel to the axis of the input shaft 50a of the operator device 50, and it assumes an operating form, and as shown in Figure 3, if the arm 2 is twisted 180° and laid down, the arm 2 and knob 3 assume a stored form along the main body of the operator device 50.

[0026] Furthermore, when the arm 2 is in a position where it is completely erected relative to the base 1, the convex shaft 22a, which is the rotation center of the knob 3, is parallel to the input shaft 50a of the operator device 50, and when the arm 2 is in a position where it is completely reclined relative to the base 1, the convex shaft 22a, which is the rotation center of the knob 3, tilts closer to the window W as it moves away from the input shaft 50a of the operator device 50. Therefore, in the stored form shown in Figure 3, the retractable handle H has a smart appearance.

[0027] Furthermore, since such a retractable handle H does not protrude much from the operator device 50 when in the retracted state, it is unlikely to interfere with a roll curtain or the like that moves up and down along the window W, and is unlikely to obstruct the view from the window W.

[0028] (switch mechanism) As shown in Figure 4, the switch 4 is slidable in the axial direction of the crank portion 21, and is connected to a stopper 41 that faces a recess 12b formed in the arm receiving portion 12 of the base 1.

[0029] The recesses 12b are located at two locations on the inclined end surface 12a of the arm receiving portion 12, one facing the portion closest to the base portion 11 and the other facing the portion farthest from the base portion 11.

[0030] The stopper 41 slides in the axial direction of the crank portion 21 together with the switch 4, and is biased by a spring 42 in a direction in which the tip portion fits into the recess 12b.

[0031] According to such a switch mechanism, when the stopper 41 is fitted into and engaged with the recess 12b, as shown in FIG. 4(a), the arm 2 is prevented from twisting, and the arm 2 cannot be raised or lowered.

[0032] On the other hand, as shown in Figure 4(b), when the switch 4 is pulled toward the knob 3 against the biasing force beyond the stroke S corresponding to the depth of the recess 12b, the stopper 41 comes out of the recess 12b, allowing the arm 2 to twist and allowing the arm 2 to be raised or lowered.

[0033] For this reason, the arm 2 can be switched between preventing and allowing twisting by the switch 4 when it is in a position where it is completely upright relative to the base 1 and when it is completely reclined, and in any position between these positions, the switch 4 cannot be used to switch between preventing and allowing twisting, and twisting is always allowed.

[0034] Therefore, when switch 4 is operated to allow twisting of arm 2 and arm 2 is twisted around the axis of crank portion 21, as soon as the tip of stopper 41 coincides with recess 12b, stopper 41 automatically fits into recess 12b due to the biasing force of spring 42, preventing twisting of arm 2 and fixing arm 2 in a fully upright or fully reclined position relative to base 1.

[0035] <Effects> In the above-described retractable handle H, as shown in FIG. 1, by operating switch 4 to allow twisting of arm 2, arm 2 can be easily raised and lowered simply by twisting it about the axis of its crank portion 21 relative to base 1, so that arm 2 can be quickly raised from the collapsed storage state to the operating state.

[0036] As shown in Figure 2, when the stopper 41 engages with one of the recesses 12b, twisting of the arm 2 relative to the base 1 is prevented during the rotation operation of the arm 2 to open or close the window W, and the arm 2 is prevented from falling over, so that the arm 2 is securely fixed in an upright position, and the arm 2 can be rotated continuously in a stable operating form to open and close the window W.

[0037] Also, as shown in Figure 3, when the window W is not being opened or closed, the arm 2 can be completely collapsed into a storage position and the stopper 41 can be engaged with the other recess 12b, thereby fixing the arm 2 along the surface of the operator device 50 so that it does not take up too much space.

[0038] <Other> The base 1 and arm 2 of this retractable handle H may be made of synthetic resin such as glass fiber-reinforced polyamide or may be made of die-casting. The knob 3 may be made of synthetic resin such as polyamide, and the knob base 31, switch 4, and stopper 41 may be made of synthetic resin such as polyacetal that has excellent rigidity and wear resistance.

[0039] Furthermore, the window W to which this retractable handle H is applied may be a vertical sliding window, a horizontal sliding window, or any other casement window that opens and closes around a hinge.

[0040] In the above embodiment, the switch 4 is exemplified as one that slides in the axial direction of the crank portion 21 of the arm 2, but the switch 4 may be a push button type that extends and retracts in the radial direction of the crank portion 21. In this case, the switch 4 is biased in the protruding direction and is provided with a stopper 41, and the arm receiving portion 12 of the base 1 is formed with a circumferential groove having a recess 12b on the surface that interfaces with the crank portion 21.

[0041] As a result, when the switch 4 is in a protruding state, the stopper 41 engages with the recess 12b, preventing twisting of the arm 2, and when the switch 4 is pushed in against the biasing force and retracted, the stopper 41 disengages from the recess 12b and rotates within the circumferential groove, allowing twisting of the arm 2.

[0042] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. Therefore, the scope of the present invention is defined by the claims, and it is intended to include all modifications within the meaning and scope of the claims.

[0043] For example, the twist angle of the crank portion 21 relative to the base 1 is not limited to 180°, but can be set arbitrarily to, for example, 90°, 150°, or the like.

[0044] Furthermore, although it has been stated that the positions at which it is possible to switch between preventing and allowing twisting of the arm 2 relative to the base 1 are the "fully upright position" and the "fully reclined position," it is not intended to be strictly limited to these positions, and slight wobbling due to backlash, etc., which is provided to allow for variations in the processing of the stopper 41 and the width of the recess 12b in the twisting direction, is naturally allowed.
