  The present invention relates to a lever handle provided mainly in a living room of a house.

  The lever handle and knob provided in the joinery are configured such that the latch bolt can be retracted from the seat provided on the frame side by pushing down or turning them, and the joinery can be opened. In the normal state, the state of being inserted into the above-described seat by the spring force is maintained, and the hinged door is prevented from being naturally opened by wind or the like.

  Such a lever handle is often used in a house from the viewpoint of convenience and support for the elderly.

JP2003-239651A JP2001-020637

  Here, the lever handle is almost spaced from the front of the joinery by about 6 cm to 8 cm because of the operation of putting the hand down and pushing it down.

  In other words, the lever handle protrudes 6 cm to 8 cm horizontally from the joinery. For this reason, for example, when the hinged door is opened to the hallway side, the lever handle hits the wall of the hallway, and the effective width of the hallway is Decrease.

  Actually, since the door handle is provided on the floor and joinery so that the lever handle does not hit the wall of the hallway, the effective width of the corridor that can actually be used is further reduced to about 10 cm. As a result, the hallway becomes narrower and the wheelchair can pass There was a problem that it became difficult to carry out and carry in furniture.

  In addition, Japanese Patent Laid-Open No. 2001-020637 discloses a technique for tilting the handle body upward. However, when a thumb turn is provided immediately above the lever handle, in the above method, the handle body and the thumb turn are separated. Due to the interference, there has been a problem that the handle body cannot be tilted to the joinery side.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a lever handle that can sufficiently secure the effective width of the hallway.

  In order to achieve the above object, the lever handle according to the present invention, as described in claim 1, has a projecting portion in which a square core inserted through a square hole of an advance / retreat mechanism for advancing / retreating a latch bolt is fixed to one end, A lever handle comprising an L-shaped handle main body connected to the other end of the protruding portion via a predetermined connecting member, the L-shaped handle main body having one end connected to the protruding portion A base end portion and a grip portion extending from the other end of the base end portion in a direction substantially orthogonal to the material axis, and the connecting member is formed in a rod shape having a non-circular cross-sectional shape, and one end thereof is formed. While pin-joining the other end of the projecting portion, the other end of the connecting member is inserted into an insertion hole provided in the base end portion so that the base end portion can advance and retreat by a predetermined stroke, and the base When the end portion is in the advanced position, the end surface of the base end portion and the end of the protruding portion DOO abuts in which the handle body when the proximal end portion is in the retracted position is configured to be retractable in joinery side by the pin junction.

  Further, the lever handle according to the present invention is configured such that the connecting member is provided with a slit, and a stopper fixed to the base end is inserted into the slit to restrict the advancing and retreating operation of the base end. It is.

  In the lever handle according to the present invention, when it is desired to secure the effective width of the corridor as much as possible with the joinery open, the handle portion of the handle body is grasped by hand, and the grip portion is moved to the retracted position of the base end portion. Pull away from the joinery surface.

  Then, the connecting member comes out of the insertion hole in the base end portion, and the handle body can be freely rotated via the pin joint.

  For this reason, if the gripping portion is lightly pushed down in such a state, or the handle body can be naturally lowered by the weight of the handle body toward the fitting surface.

  At this time, since the lever handle of the present invention is in a state where only the projecting portion projects from the surface of the joinery, the effective width of the hallway can be sufficiently secured.

  On the other hand, when it is desired to return the lever handle of the present invention to a normal state, the handle body is raised from the surface of the joinery by holding the handle portion of the handle body by hand and then the base end portion moves from the retracted position to the advanced position. The connecting member is inserted into the insertion hole of the base end portion by pushing and the end surface of the base end portion is brought into contact with the end surface of the projecting portion.

  Thus, when the connecting member formed in the non-circular cross-sectional shape is inserted into the insertion hole of the base end portion, the force for pushing down the grip portion is transmitted to the projecting portion as a rotational force. Similarly, the latch bolt can be retracted through the square core to open the joinery.

  When pushing and pulling the grip portion to move the base end portion back and forth, various configurations are conceivable as to how the base end portion is advanced and retracted. For example, a slit is provided in the connecting member, and the base end portion is moved. A stopper fixed to the end can be inserted into the slit to limit the forward / backward movement of the base end.

  For example, the stopper may be constituted by a pin that can be inserted into the slit of the connecting member, and the pin may be inserted from the outer peripheral surface of the base end portion and inserted into the slit.

  In the state where the base end is advanced to the advance position and the end face is in contact with the end face of the projecting portion, it is necessary to prevent the handle body from wobbling. For example, the inner dimension of the insertion hole may be made to substantially coincide with the cross-sectional dimension of the connecting member.

  In this configuration, the connecting member is fitted into the insertion hole, and the wobbling of the lever body can be prevented by this fitting force.

  Embodiments of a lever handle according to the present invention will be described below with reference to the accompanying drawings. Note that components that are substantially the same as those of the prior art are assigned the same reference numerals, and descriptions thereof are omitted.

  FIG. 1 is an overall perspective view showing a lever handle according to the present embodiment together with related parts, and FIG. 2 is a vertical sectional view and a horizontal sectional view. As can be seen from these drawings, the lever handle 1 according to the present embodiment includes a projecting portion 2 projecting from the surface of the hinged door 11 and a handle body 3 connected to the projecting portion.

  One end of a square core 7 inserted through the square hole 6 of the advance / retreat mechanism 5 for advancing and retracting the latch bolt 4 is fixed to the projecting portion 2, and the handle body 3 is a base end connected to the projecting portion 2. The portion 8 and a grip portion 9 extending from the opposite end portion of the base end portion in a direction substantially orthogonal to the material axis of the base end portion are formed in a generally L shape as a whole.

  An insertion hole 12 is formed in the base end portion 8, and the projecting portion 2 and the base end portion 8 are connected to each other via a strip-shaped connecting member 13 inserted into the insertion hole.

  One end of the connecting member 13 is in pin contact with a pin joint portion 16 provided in the projecting portion 2, and the slit 14 formed from the other end to the vicinity of the center restricts the forward / backward movement of the connecting member 13. A rod-shaped stopper 15 is penetrated.

  The insertion hole 12 has an inner dimension that is substantially the same as the thickness and width of the connecting member 13, and has a depth that prevents the tip of the connecting member 13 from hitting the bottom when the connecting member 13 is inserted.

  With this configuration, when the base end portion 8 is pushed into the projecting portion 2 side, the connecting member 13 is inserted into and fitted into the insertion hole 12, and the connecting member 13 and the insertion hole 12 are inserted. A fitting force is generated between the two.

  The slit 14 can push the base end portion 8 toward the projecting portion 2 to its advanced position so that the end surface abuts against the end surface of the projecting portion 2, and the base end portion 8 from the projecting portion 2. When pulling out, it is locked by the stopper 15 at its retracted position, and at that retracted position, the stroke length is determined so that the handle body 3 can be rotated downward and tilted to the joinery side. What is necessary is just to form.

  In the lever handle 1 according to the present embodiment, when the joinery 11 remains open and the effective width of the corridor is to be secured as much as possible, the grip portion 9 of the handle body 3 is grasped by hand, and the base end portion 8 is retracted. Pull the grip 9 to the position away from the joinery surface.

  Then, the connecting member 13 comes out of the insertion hole 12 of the base end portion 8, and the handle main body 3 can be freely rotated via the pin joint.

  Therefore, in this state, as shown in FIG. 3, if the grip portion 9 is lightly pressed down, or the handle body 3 naturally falls by its own weight, the handle body falls down to the joinery surface side.

At this time, since the lever handle 3 according to the present embodiment is in a state where only the projecting portion 2 projects from the surface of the joinery as shown in FIG. 4, the effective width of the corridor is as shown in FIG. It becomes larger than the conventional W ₂ (FIG. 2B) and becomes the effective width W ₁ .

  On the other hand, when it is desired to return the lever handle 3 according to the present embodiment at the normal time, the handle 9 of the handle body 3 is held by the hand and is raised from the joinery surface, and then the base end 8 is moved from the retracted position to the advanced position. The handle body 3 is pushed so as to move, the connecting member 13 is inserted into the insertion hole 12 of the base end portion 8, and the end surface of the base end portion 8 is brought into contact with the end surface of the projecting portion 2.

  As described above, according to the lever handle 1 according to the present embodiment, when the connecting member 13 formed in the noncircular cross section is inserted into the insertion hole 12 of the base end portion 8, the grip portion 9 is moved. Since the pushing-down force is transmitted to the projecting portion 2 as a rotational force, the latch bolt 4 can be retracted via the square core 7 and the fitting 11 can be opened as in the prior art. At this time, the lever handle 3 according to this embodiment is in a state where only the projecting portion 2 projects from the surface of the joinery, so that the effective width of the corridor can be sufficiently secured.

  Further, according to the lever handle 1 according to the present embodiment, since the end surface of the base end portion 8 is normally brought into contact with the end surface of the projecting portion 2, the projecting portion 2 and the base end portion 8 have the same diameter. If configured in the same color, the aesthetic appearance of the conventional lever handle can be maintained almost as it is.

  Further, according to the lever handle 1 according to the present embodiment, since the inner dimension of the insertion hole 12 is substantially matched with the cross-sectional dimension of the connecting member 13, the proximal end portion 8 is advanced to the advanced position, and the end face is projected. In the state of being brought into contact with the end face of the portion 2, the connecting member 13 is fitted into the insertion hole 12, and the wobbling of the lever body 3 can be prevented by this fitting force.

  Further, according to the lever handle 1 according to the present embodiment, the handle main body 3 is tilted downward, so that there is no fear of interfering with the thumb turn 10 (FIG. 1) that is often installed immediately above the lever handle.
