Description

  The present invention relates to a pull handle with an assist mechanism (open assist mechanism) that can be opened with a small force at the time of initial start for opening a sliding door.

  In a sliding door represented by a sash, an airtight member such as a bead or mohair is interposed between the vertical wall of the door and the window frame or the opening frame in order to increase the airtightness of the closed state of the sliding door. It is. In particular, the sash window is provided with an attracting device, an airtight device, and the like, so that the resistance at the time of opening is large. In addition, recently, heat-insulating sashes are becoming mainstream from the viewpoint of energy-saving effects, but the sliding doors of heat-insulating sashes are often equipped with paired glass, and the walls are often double-structured, so the overall weight is heavy. I have to be. In particular, large glass shojis have a problem that they are not easy to open for the elderly and sick.

  In order to improve the opening / closing operability of such a shoji, there is known an assist mechanism-equipped puller that applies the lever principle so that the shoji can be opened with a small force at the initial opening of the shoji.

  For example, in the following Patent Document 1, a middle part of a lever handle is rotatably attached to a pedestal fixed to a door tip of a sliding door, a kick that can grip one end of the lever handle and press the other end of the vertical frame of the sliding door frame. In the opening device that opens the sliding door by the reaction force when the sliding door frame is pressed by the kicking portion by operating the grip and turning the lever handle by operating the grip, the pedestal has an opening parallel to the surface of the sliding door A sliding door opening device has been proposed in which a lever handle is passed through the opening, and the lever handle is passed through the opening so that the intermediate portion and the kick-out portion of the lever handle can be accommodated when not operated.

  Moreover, in the following Patent Document 2, a fixing part provided on a door toe of a shoji in a sliding window or a sliding window, and an operation part that is slidably attached to the fixing part in the opening / closing direction of the shoji, In a state where the shoji is closed, the pivot is pivotally supported by the fixed portion, and one end of the pivot is pivotally connected to the operation portion, and the rotation portion rotates with the slide of the operation portion. By sliding the operation part in a direction away from the vertical frame of the sliding window or the single sliding window with which the door toe contacted, the other end of the rotated rotating part protrudes toward the vertical frame. In addition, there has been proposed a handle with an opening assist mechanism that abuts the vertical frame and urges the shoji in a direction away from the vertical frame.

Japanese Patent Laid-Open No. 2003-13634 JP 2005-97933 A

  However, in the case of the opening device according to Patent Document 1, since the lever protrudes from the main body attached to the shoji downpile, the appearance is bad, the curtain interferes with the body, etc. As the lever protrudes inward, there is a large amount of unfolded shoji when opening the window, the width of the opening is narrowed, and the screen door packing is used to summon the shoji. There is a problem that a problem of not touching the rice cake occurs or that the size of the summon bowl needs to be increased.

  The handle according to Patent Document 2 has a structure in which the handle is overlapped with the upper surface of the main body attached to the shoji downpile, so that many of the above-mentioned problems are solved, but the structure is complicated and component parts are also included. There are problems such as increased production costs due to the large number and difficulty in application to shoji screens that would like to narrow down the vertical width of the downspout.

  Further, even when there are protrusions (such as fins extending inward in the direction of finding) on the window frame side, in order to reduce the residual at the time of opening the window and ensure a sufficient opening width, The gap between the protrusion and the handle will be set small, but if you do so, when you pick up the handle and close the shoji, there is a risk that your fingers will get caught between the protrusion and the handle was there.

  Furthermore, in the case of the devices or pullers according to Patent Documents 1 and 2, the swing angle of the lever on the driving side (or the rotating portion rotated by the movement of the pulling hand) and the kicking member on the operating side If you want to increase the protruding amount of the kicking member, it is necessary to swing the lever more or secure a large amount of movement of the puller. There was a problem such as bad.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to eliminate the protrusion of the lever and reduce the found width. Even if there are protrusions (such as fins extending inward in the direction of finding) on the window frame side, when the shoji is closed, the fingers between the protrusions and the handle are caught. Is to avoid it.

  In order to solve the above-mentioned problem, the present invention according to claim 1 is arranged so as to overlap the pedestal portion and the upper surface of the pedestal portion, and swing by being pivotally supported by the pedestal portion at the lower end side or the upper end side. An operation lever that is movable and has a finding width substantially equal to the finding width of the pedestal, and a recess or a step formed in the pedestal, and an intermediate part is pivotally supported by the pedestal The end portion on the side where the pedestal portion and the operating lever are pivotally supported is pivotally supported by the operating lever, and swings as the operating lever swings, thereby opening the window frame. A kick-out member that kicks out and gives an initial starting force, and a finger-stand standing wall is formed on the upper surface of the operation lever, and the finger-stand standing wall is biased to a position on the inner side of the sliding door The handle with an assist mechanism is characterized by It is subjected.

  In the first aspect of the present invention, the operating lever is arranged so as to overlap the upper surface of the pedestal portion, and the operating lever has a finding width substantially equal to the finding width of the pedestal portion. As well as no interference with others.

  In addition, there is less leftover during opening of the window, and a sufficient opening width can be secured, so that there is no problem that the screen door packing does not come into contact with the summons of the shoji and the dimensions of the summons can be found. There is no need to make the size particularly large. Furthermore, since the basic component member has a simple structure including a pedestal portion, an operation lever, and a kick-out member, the manufacturing cost is reduced.

  In the pull handle with the assist mechanism, a standing wall for finger hanging is formed on the upper surface of the operation lever, and the standing wall for finger hanging is biased to a position on the inner side of the sliding door. Therefore, even when there are protrusions (fins extending inward in the direction of finding) on the window frame side, when closing the shoji, if you hold the standing wall for this finger and close the shoji, It is possible to eliminate an accident in which a finger is caught between the window frame and the handle.

  Furthermore, the pulling handle with the assist mechanism is provided with the finger-stand standing wall biased to a position on the inner side of the sliding door, so that the pulling handle can be attached to the window frame or in a considerably close state.

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

  FIG. 1 is a perspective view (normal time) of a pull handle 1 with an assist mechanism according to the present invention, FIG. 2 is a perspective view showing an operating state during a shoji opening operation, FIG. 3 is a plan view, and FIG.

  As shown in FIGS. 1 to 4, the pull handle 1 with an assist mechanism is basically arranged on a pedestal portion 2 attached to a vertical frame of the shoji window frame and overlaid on the upper surface of the pedestal portion 2. The control lever 3 is pivotable by being pivotally supported by the pedestal portion at the lower end side or the upper end side, and is located between the operation lever 3 and the pedestal portion 2 so as to have a substantially equal width as the locating width of the pedestal portion. The intermediate portion is pivotally supported by the pedestal portion so as to be swingable, and the pivotal support side end portion of the pedestal portion 2 and the operation lever 3 is pivotally supported by the operation lever 3. And a kicking member 4 that swings as the operating lever 3 swings and kicks out the window frame to give an initial starting force. A standing wall 34 for hooking a finger is formed on the upper surface of the operating lever 3. At the same time, the finger-hanging upright wall 34 is biased to a position on the inner side of the sliding door. Those provided by.

  This will be described in more detail below.

  As shown in detail in FIG. 5, the pedestal portion 2 is a substantially cubic member that is formed in a rectangular shape in a longitudinal direction in plan view, and an intermediate portion in the longitudinal direction of the member accommodates the kicking member 4. A recess 20 is formed, and a shaft installation hole 21 for pivotally supporting the kick-out member 4 is formed in the recess 20. In addition, screw holes 22 and 23 are formed in the upper and lower parts for mounting on the shoji vertical shaft, and a shaft installation hole 24 for pivotally supporting the operation lever 3 is formed in the lower end part. On the side, slit-shaped stopper installation holes 25 are formed on both the left and right sides. As shown in the figure, the stopper 10 has a stopper wall 10a having a relatively high height, a standing wall 10b having a relatively low height, and a coupling portion 10c for coupling them. The stopper wall 10a and the standing wall 10b are installed from the back side of the pedestal portion 2 so as to be fitted in the stopper installation holes 25, 25, respectively, and only the stopper wall 10a. Projecting from the upper surface of the base 2. Depending on whether the stopper wall 10a protrudes from the left or right stopper installation hole 25, the rotation of the operation lever 3 to be described later to one side is restricted. That is, by making it possible to arbitrarily set the regulating direction of the operation lever 3, the sliding lever can be used in common on either side of the left and right doors. Further, the swing of the operation lever 3 can be suppressed by the stopper 10 during the closing operation of the shoji, and a load load is not applied to the shaft portion when the stopper 10 receives the closing operation force. Note that the rectangular and slightly raised portion 27 provided on the side surface of the pedestal portion 2 is a contact portion for the summoning ridge when the shoji is fully opened.

  A spring installation hole 26 is provided at an upper position of the operation lever shaft installation hole 24, and as shown in FIG. 4, half of the fitted spring 5 is hooked on the base portion 2, and the other half is By being applied to the operation lever 3 side, when the operation lever 3 is swung, a biasing force is applied to return the operation lever 3 to the original vertical position by the restoring force of the spring member. As shown in FIG. 4, a back cover 6 is provided on the back side of the pedestal portion 2 with the stopper 10 installed, and the back cover 6 is used for pivotally supporting the kick-out member 4. The shaft member 8 for supporting the shaft member 7 and the operation lever 3 also serves as a member for bearing on the back surface side.

  As shown in detail in FIG. 6, the operation lever 3 is a substantially cube-shaped member that is formed in a rectangular shape in a longitudinal direction in plan view, and has a width (short side dimension) substantially equal to the locating portion 2. It is set to an equivalent finding width, and is disposed so as to overlap the upper surface of the pedestal portion 2. The shaft member 8 is pivotally supported by the pedestal portion 2 by the shaft member 8 installed in the shaft installation hole 30 formed on the lower end side, and the kick member 4 is provided on the upper side of the shaft installation hole 30. A shaft installation hole 31 for supporting the shaft is formed. The hole 32 provided at the lowermost end is an insertion hole for allowing a screw for fixing the base portion 2 to pass therethrough. A cover material 11 for covering the shaft installation holes 30 and 31 and the insertion hole 32 is detachably provided.

  A cutout 33 is provided on the side wall of the operation lever 3 in a shape that substantially matches the shape of the distal end side of the stopper wall 10a. The peripheral edge of the notch 33 is cut obliquely, the front end side peripheral edge of the stopper wall 10a is processed into a semicircular arc shape, and only the front end side peripheral edge abuts on the peripheral edge of the notch 33. Yes. Thus, when viewed from the front, the stopper wall 10a does not protrude outward and is hidden by the operation lever 3.

  A finger-standing standing wall 34 is formed on the upper surface of the operation lever 3, and the finger-hanging standing wall 34 is biased to a position on the sliding door inner side (the sliding door opening direction side). . The finger-hanging standing wall 34 is provided only at the position on the sliding door inner side, and the finger-hanging standing wall does not exist at the position on the sliding door outer side.

  As shown in detail in FIG. 7, the kick-out member 4 is dimensioned to be accommodated in the recess 20 of the pedestal portion 2, and is covered and not exposed by the operation lever 3 when viewed from the front. Dimension. A shaft installation hole 40 for pivotally supporting the pedestal portion 2 by the shaft member 7 is formed slightly below the center, and the shaft member 9 is pivoted by the shaft member 9 with respect to the operation lever 3 at a lower position thereof. A shaft installation hole 41 for supporting is formed. Further, detachable contact members 12 are fitted on both side surfaces which are contact surfaces with respect to the window frame. By providing the detachable contact member 12 at the window frame contact portion of the kick-out member 4, even if the contact portion with the window frame is worn by friction, it can be dealt with only by replacing the contact member. It becomes possible. The shaft installation hole 41 is a long hole extending in the vertical direction, and the swing range of the operation lever 3 is determined by the length of the long hole.

  In the pull mechanism 1 with the assist mechanism described in detail above, as shown in FIG. 2, when the finger is pulled up in the opening direction by placing a finger on the finger-hanging standing wall 34 of the operation lever 3, the operation lever 3 pulls the shaft member 8. Oscillation starts with the oscillation center. When the operating lever 3 swings, the shaft member 9 that is a connecting portion with the kicking member 4 swings in the same direction, and accordingly, the upper end side (the kicking side) of the kicking member 4 is the window frame. It swings so as to protrude in the direction, and kicks out the window frame to give an initial starting force.

  By the way, in the kicking member 4, the position of the shaft member 9 connecting the kicking member 4 and the operation lever 3 is such that the swinging angle β of the kicking member is larger than the swinging angle α of the control lever 3. It is better to set the position. In the handle of the present invention in which the operation lever 3 and the kick-out member 4 are not integrated with each other, the setting of the pivot position between the kick-out member 4 and the operation lever 3 is changed to change the swing of the operation lever 3. It is possible to arbitrarily set the swing angle of the kicking member 4 with respect to the moving angle. Therefore, the pivoting portion of the kicking member 4 and the operation lever 3 is set at a position where the swinging angle of the kicking member 4 is larger than the swinging angle of the control lever 3, so that the swinging of the control lever 3 is small. A large kicking amount can be obtained by the operation, and the operability can be improved by reducing the swinging operation amount of the operation lever 3. Specifically, as shown in FIG. 8, when the swing angle of the operation lever 3 is α, the swing angle β of the kick-out member 4 depends on the separation distance S between the shaft member 7 and the shaft member 9. Therefore, the separation distance S is set so that the kick member swing angle β> the control lever swing angle α. Of course, the amount of protrusion of the kicking member 4 also varies depending on the length of the member from the shaft member 7 to the tip of the kicking side, but by securing a large swing angle β of the kicking member 4, the number of operation levers 3 is small. It can be kicked out with the amount of operation, improving operability.

  For example, in FIG. 8, an example in which the separation distance L between the shaft member 7 and the shaft member 8 is 45 mm and the separation distance S between the shaft member 7 and the shaft member 9 is 19.05 mm will be described based on FIG. Then, as shown in FIG. 9B from the state before the operation of FIG. 9A, when the operation lever 3 is swung by 5.0 °, the swing angle β of the kicking member 4 is 7.4 °. As shown in FIG. 9 (C), when the operating lever 3 is swung 13.6 °, the swinging angle β of the kicking member 4 becomes 18.7 °, and as shown in FIG. 9 (D). When the operation lever 3 is swung by 17.9 °, the swinging angle β of the kicking member 4 becomes 23.2 °.

  Next, FIG. 10 shows an example in which the pull handle 1 with the assist mechanism is attached to the sash window. The sash window is installed in the window frame 16 so that the outer shoji 14 and the inner shoji 15 are slidable, and includes a screen door 13 outside the shoji. In the present example, the pull handles 1 and 1 with the assist mechanism are attached to the window frame side downspout of the external shoji 14 and the window frame side downspout of the inner shroud 15, respectively. On the side of the external shoji 14, a projecting piece for attaching an airtight material is used as a contact target member of the kick-out member 4. However, as shown on the side of the internal shroud 15, a contact target member 6 is provided separately. Also good.

  As shown in FIG. 10 (B), in the pull handle 1 with the assist mechanism, the protrusion of the lever can be eliminated and the width of the finding can be made small, so that the undrawn portion at the time of opening the window can be reduced, and a sufficient opening width is secured. As well as being able to do so, there is no problem such as the packing of the screen door 13 not being in contact with the summon bowl of the external shoji 14.

  By the way, as shown in FIG. 10, the window frame 16 is formed with fins 16a extending inward in the direction of finding on the front side of the pull handle 1, but when closing the shoji from the open window state, As shown in FIG. 11, if the sliding door 14 is closed by holding the finger-hanging standing wall 34 with the thumb and forefinger or the like, the accident that the finger is pinched between the window frame 16 and the handle 1 is eliminated. Can do.
