[0001]

[Industrial applications]

 The present invention relates to a handle assembly suitable for being attached to a panel such as a door panel and used for opening and closing the panel.

[0002]

[Prior Art]

 In a combination of a wall as a fixed side panel and a door panel as a movable side panel, a handle and a sleeve fitted to a turning shaft of the handle are used as a handle assembly used for opening and closing the door panel. 2. Description of the Related Art A handle assembly of a type that includes a nut member for fixing a sleeve to a movable side panel, and a handle is rotatably attached to the movable side panel via this sleeve is well known.

If such a handle is locked at the start and end points of its turning and the handle itself can be kept stationary, it is necessary to turn the handle frequently when opening and closing the door. It is convenient without However, there is no conventional technology that realizes such a function with a simple mechanism.

[0004]

[Problems to be solved by this device]

 The conventional handle assembly has a complicated structure and a high manufacturing cost even if the turning handle can be stopped at each of the start point and the end point. Therefore, the handle assembly is usually made to stand still at either the start point or the end point, in many cases only at the start point. When such a handle assembly is provided with a claw fitting that is interlocked with its turning, the handle must be turned from the start point to the end point each time the panel is opened and closed, and the operation is troublesome.

In view of this, the present invention provides a notch on the end edge of the sleeve or a cam groove extending along the circumferential direction on the outer periphery of the side wall of the sleeve, and the notch as a cam follower at the tip of the trigger member. Another object of the present invention is to solve the above problems by a simple structure in which the swing of the handle assembly is locked by fitting it in the cam groove.

[0006]

[Action and effect]

 The sleeve has a notch at each position corresponding to the start and end of the handle turning, or a deep cam groove is provided, and the tip of the trigger member is fitted in this notch or groove under the spring bias. Since they match, the turning of the steering wheel is locked at the start point and the end point. In particular, by providing the first cam groove on the outer circumference of the side wall of the sleeve, the end edge of the side wall is connected without being cut, and even if the cam follower of the trigger member twists the side wall in the cam groove, The side wall is not easily deformed or damaged.

The cover provided on the handle can be brought close to or in contact with the bearing wall of the trigger member to support the bearing wall which tends to be deformed and to function to reinforce the bearing wall.

Therefore, the handle assembly according to the present invention is not easily damaged even if it is used for a heavy moving side panel.

【Example】

 The details of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view showing a usage state of a handle assembly 1 according to the present invention. The handle assembly 1 is attached to a movable side panel 3 which is openable and closable via a hinge (not shown) with respect to a fixed side panel 2 of which a wall is an example. Handle Set The solid 1 is operated by gripping the handle 4 and the trigger member 10 inside thereof. The handle assembly 1 has a claw metal fitting 5 inside the movable side panel 3, the claw metal fitting 5 pivots in conjunction with the handle 4, and fits into a groove of a groove metal fitting 6 provided inside the fixed side panel 2.・ It detaches and functions as a locking member for the moving side panel 3. In FIG. 1, the handle assembly 1 is in the locked state, and when the handle 4 is turned in the direction of the arrow 7, the claw fitting 5 is disengaged from the groove fitting 6 and the panel 3 can be freely opened.

FIG. 2 is a sectional view taken along line II-II in FIG. In the figure, the handle 4 has a swivel shaft 8 which is at a right angle to the surface of the movable side panel 3, and the handle 4 can swivel around this shaft 8 as will be described later in detail. The handle 4 is provided with a trigger member 10 which is supported by a pivot pin 9 so as to be able to swing vertically with respect to its swiveling surface. The pivot pin 9 is supported by a pair of bearing walls 11 (see also FIG. 5) provided on the handle 4 so as to sandwich the trigger member 10 from both sides. A coil spring 12 is interposed between the trigger member 10 and the handle 4, and the trigger member 10 is biased counterclockwise in the figure around the pivot pin 9. The trigger member 10 has a pivot pin 9 as a fulcrum, and one end of the trigger member 10 is a working end 10A on which the hand of the person holding the handle 4 acts, and the other end is a cam follower 10B. The free end 8D of the swivel shaft 8 penetrates the handle mounting hole 13 of the moving side panel 3, and the locking claw fitting 5 is bolted to the tip inside the panel 3 (right side of the panel 3 in FIG. 2). 14, the retainer ring 15, the washer 16 and the like. The handle 4 and the claw fitting 5 are provided with a well-known technique in which the free end 8D of the handle 4 and the fitting hole of the claw fitting 5 fitted to the handle 4 are formed in a rectangular shape in order to integrally rotate them. ..

Further, in FIG. 2, a sleeve 20 is fitted on the outer side of the rotary shaft 8. The sleeve 20 is always fitted to a predetermined position of the swivel shaft 8 by contacting the step 21 with a step 37 which is one of the steps generated by reducing the diameter of the swivel shaft 8. The flange portion 22 of the sleeve 20 contacts the outside (left side in the figure) of the moving panel 3 via the rubber sheet 23, and the nut 24 is screwed from the inside of the panel 3 so that the nut 24 is retained by the retainer ring 25. The sleeve 20 is fixed to the panel 3 by abutting on the panel 3 via the and tightening the nut 24 firmly. The flange 22 has a plurality of protrusions 26, which fit into the fitting holes 36 formed in the panel 3 and prevent the sleeve 20 from rotating. Inside the panel 3, the free end 27 of the sleeve 20 abuts on the washer 16 described above, so that the sleeve 20 and the swivel shaft 8 are slidable in the circumferential direction but are prevented from falling off. There is. The sleeve 20 is also in engagement with the trigger member 10 as follows. A first cam groove 30 extends circumferentially on the outer periphery 29 of the side wall 28 of the sleeve 20. On the other hand, the cam follower 10B of the trigger member 10 is fitted to the side wall 28 from the outside in the radial direction. The illustrated example shows a state in which the swivel shaft 8 in which this fitting is inscribed in the sleeve 20 can swivel but cannot move in the left and right horizontal directions, that is, in the lateral direction.

FIG. 3 is a perspective view showing details of the cam follower 10 B of the trigger member 10 and the cam groove of the sleeve 20. The trigger member 10 has a fitting hole 9A for the shaft support pin 9 and swings in the direction of arrow 40 with the shaft support pin 9 fitted therein as a fulcrum. One end of the trigger member 10 is a cam follower 10B, and the cam 10B has a first cam surface 10C, a second cam surface 10E which is a part of the side surface L-shaped protrusion 10D, and a third cam surface 10E. And a cam surface 10F. The sleeve 20 is symmetrical with respect to the III-III axis. As a result, the handle assembly 1 becomes a left / right type in which the turning direction can be selected to either left or right. This is a conventional technique for this type of handle, and a description thereof will be omitted. Therefore, here, the configuration of the cam groove will be described only for the right half when the III-III line is the center line. The sleeve 20 has a first cam groove 30 that extends in the circumferential direction on the outer periphery 29 of the side wall 28, and a second cam groove 31 that extends from one end thereof to the edge of the side wall 28 at a right angle. The first cam groove 30 has a first groove portion 32 and a third groove portion 34 formed at both ends thereof so that the depth of the cam groove is particularly deep and the shape thereof is formed so that the protrusion 10D of the trigger member 10 can be fitted thereto. The second groove portion 33 is formed between the both groove portions so as to be relatively shallow, and the shape thereof is formed so that the third cam surface 10F of the trigger member 10 is fitted. The third groove 34 is formed as a through hole that penetrates the inside and outside of the side wall 28 so that the locking member 51 described later can be fitted therein. The first cam groove 30 intersects the second cam groove 31 at a right angle in the first groove portion 32, and the first groove portion 32 is formed deeper than the second cam groove 31. The width of the second cam groove 31 is slightly larger than the width W of the protrusion 10D of the trigger member 10. Therefore, in order to fit the sleeve 20 to the swivel shaft 8, the protrusion 10D and the second cam groove 31 are aligned with each other, and the protrusion 10D is moved and fitted so as to follow the second cam groove. When the step 21 of the sleeve 20 comes into contact with the step 37 of the pivot 8, the cam follower 10B and the first groove 32 of the first cam groove 30 are engaged with each other.

FIG. 4 is a schematic cross-sectional view showing a series of fitted states of the first cam groove 30 and the cam follower 10B as the handle 4 turns. FIG. 4A shows a state in which the cam follower 10B is fitted in the first cam groove 30 and the first groove portion 32. The chain line shows the state when the trigger member 10 is swung in the clockwise direction, and the projection 10D is separated from the first groove 32. In this state, the handle 4 can be swiveled to move to (B) or can be horizontally moved to be disengaged from the sleeve 20. FIG. 4B shows a state in which the cam follower 10B is fitted in the second groove portion 33. The third cam surface 10F is fitted in the second groove portion 33, and the second cam surface 10E is in contact with the outer circumference 29 of the sleeve 20. The second groove portion 33 functions as a groove for guiding the turning of the handle 4. FIG. 4C shows a state in which the handle 4 is further turned and the cam follower 10B is fitted in the third groove 34. The second and third cam surfaces 10E and 10F are set in the third groove portion 34 which is a through hole. The third groove portion 34 is formed deeper than the second groove portion 33, and when the handle 4 turns from (B) to (C), the trigger member 10 swings in the counterclockwise direction, and the swinging thereof occurs. It stops when the first cam surface 10C comes into contact with the side wall 29 of the sleeve 20. In this way, the rotation of the handle 4 is accompanied by the movement of the cam follower 10B shown in FIGS. (A) and (C) respectively correspond to the starting point or the ending point of the turning, and are usually used with the state of (C) being the position of the handle 4 shown in FIG. In order for the handle 4 to move from the position (A) or (C) to the position (B), the trigger member 10 must be swung clockwise. This means that the turning of the handle 4 is in the locked state at the positions (A) and (C), and the trigger member 10 must be rocked once to unlock the lock.

When the handle 4 and the sleeve 20 configured as described above are in the positional relationship of (B) or (C) in FIG. 4, the cam follower 10B and the first cam groove 30 mesh with each other, Both are inseparable. If these are attached to the moving side panel 3 through the attachment holes 13 (see FIG. 2) in their inseparable state, the labor of attachment is reduced as compared with the prior art in which these must be handled individually. It can be significantly reduced.

As shown in FIGS. 2 and 3, the handle assembly 1 may include a mechanism for locking the handle 4 separately from the lock of the handle 4. The lock mechanism 50 built in the swivel shaft 8 in FIG. 2 is for that purpose, and the lock hole cover 52 (see FIG. 1) is swung to expose the lock hole (not shown), and the lock is inserted there. When moved, the locking member 51 of the locking mechanism 50 projects outward in the radial direction of the swivel shaft 8 and fits into the third groove portion 34 (see FIG. 3) of the sleeve 20 from the inside. As a result, the member 51 straddles between the swivel shaft 8 and the sleeve 20 to lock the handle 4 by disabling the swivel of the handle 4. If the trigger member 10 is pressed by the cam follower 10B when the member 51 projects in the radial direction of the swivel shaft 8, the trigger member 10 is swung clockwise together with the locking, and the trigger member 10 is swung clockwise. It can also be stored inside.

FIG. 5 is a view taken along the line VV of FIG. However, here, only the cover member 55 in which the sleeve 20 is removed from the handle assembly 1 and fixed to the handle 4 via the screw 57 is shown. The outer diameter of the swivel shaft 8 is gradually reduced from 8A to 8D, and the rectangular portion 8D is a free end and has a screw hole 8E. A pair of support walls 11 sandwiching the trigger member 10 from both sides extend from the pivot shaft 8, and the support wall 11 supports the shaft support pin 9 (see FIG. 2). An inner projecting portion 56 of the cover member 55 is in proximity to or in contact with each bearing wall 11 from the outside. As a result, when the handle 4 is turned, even if a force for twisting the handle wall 11 is exerted, the support wall 11 itself exerts a reinforcing effect as a support from the side surface, so that it easily changes. Does not shape or break.

In FIG. 2, an O-ring 18 is fitted on the swivel shaft 8 and then a sleeve 20 is fitted to smoothen the swiveling of the handle 4. Further, in the above description, it is generally preferable that the components other than the O-ring 18 and the rubber sheet 23 are made of a metal material, but the metal material may be appropriately changed to a plastic material or the like.

Further, in the structure of the sleeve 20 shown in FIG. 3, the second cam groove 31 and the third cam groove 34 are replaced with notches extending in the axial direction from the end edge of the sleeve 20, and in addition, the second groove portion is omitted. It is also possible to do so. In this case, it is difficult to obtain the advantage brought about by the structure of FIG. 3, but it is possible to reduce the manufacturing cost of the sleeve 20.
