Description

  The present invention relates to a pulling handle with an assist mechanism (opening assist mechanism) and a sash window 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 effect, but many of them have double glass attached to the sliding doors of heat-insulating sashes. 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. There has been proposed a handle with an opening assist mechanism that abuts on the vertical frame and urges the shoji in a direction away from the vertical frame.

  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.

  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, a first object of the present invention is to eliminate the protrusion of the lever and reduce the found width. A second object of the present invention is to provide a pull handle with an assist mechanism and a sash window having a structure in which the swing angle of the kicking member can be set larger than the swing angle of the operation lever.

  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. There is provided a puller with an assist mechanism characterized by comprising a kicking member that kicks out and gives an initial starting force.

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.

  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. It also serves as a member for bearing on the back side of the shaft member 8 for supporting the shaft member 7 and the operation lever 3.

  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. In addition, a depression 34 is formed on the upper surface for hooking a finger. In addition, the hole 32 provided in the lowermost end is an insertion hole for allowing a screw for fixing the base portion 2 to pass therethrough. Moreover, the cover material 11 for covering up the said shaft installation holes 30 and 31 and the insertion hole 32 is provided so that attachment or detachment is possible.

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. 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 above-described pull mechanism 1 with an assist mechanism, as shown in FIG. 2, when the shoji is pulled in the opening direction by placing a finger on the depression 34 of the operation lever 3, the operation lever 3 swings the shaft member 8 around the center. Start swinging. 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.

  Incidentally, in the kicking member 4, the position of the shaft member 9 is preferably set to a position where the swinging angle β of the kicking member is larger than the swinging angle α 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.
