Description

  The present invention relates to a handle attachment structure for attaching a handle to a door plate constituting an open door or a sliding door.

An example of a conventional “handle attachment structure” is disclosed in Japanese Patent Laying-Open No. 2005-97991 (Patent Document 1). As shown in FIG. 10, this “attachment structure of the handle” is to attach the handle to the front and back main surfaces of the door plate 2, and the two seat plates 1 constituting the handle are arranged on the front and back main surfaces of the door plate 2. These seat plates 1 are connected to each other via a female screw shaft 7 and a male screw shaft 8. Therefore, the interval between the seat plates 1 can be adjusted by changing the screwing amount of the male screw shaft 8 with respect to the female screw shaft 7, so that the pressing force, that is, the fixing force of the seat plate 1 with respect to the door plate 2 is optimized at the time of factory shipment. In addition, the interval between the seat plates 1 is set. The reference numbers described in FIG. 10 correspond to the reference numbers described in Patent Document 1.
Japanese Patent Laid-Open No. 2005-97991

  In the conventional “handle attachment structure” (FIG. 10), the distance between the front and back seat plates 1 is determined by the screwing amount of the male screw shaft 8 with respect to the female screw shaft 7. It was not possible to follow the fluctuations. Therefore, when the thickness of the door plate 2 becomes thin due to a change in temperature or humidity, a gap is generated between the main surface of the door plate 2 and the seat plate 1, and “gap” is attached to the attachment portion of the handle by the gap. There was a risk of "tickling".

  As a means for solving this problem, it is conceivable that the seat plate 1 is directly attached to the main surface of the door plate 2 with a mounting screw. However, in this case, it is difficult to screw the mounting screw straight on site, and the workability is improved. There was a problem of getting worse. Further, in the field construction, there is a high possibility that the direction in which the mounting screw is screwed out, and there is a problem that sufficient mounting strength cannot be obtained when the direction in which the mounting screw is screwed out.

  Therefore, a main object of the present invention is to provide a handle mounting structure that can prevent the rattling of the handle mounting portion from occurring and can be easily and reliably constructed.

  The invention described in claim 1 is “connected to the handle 14 disposed on both main surfaces 12a, 12b of the front and back of the door plate 12, the through hole 16 penetrating the door plate 12 in the thickness direction, and the handle 14. And the cylindrical fixing member 20 inserted in the axial direction both ends of the said through-hole 16, and the inside of the said fixing member 20, It is said by pushing at least one part of the said fixing member 20 outward. The handle mounting structure 10 ”includes a pressing member 22 that presses the outer surface of the fixing member 20 against the inner surface of the through hole 16.

  In the present invention, the through holes 16 are provided in the door plate 12, and the fixing members 20 are inserted into both end portions in the axial direction of the through holes 16, and the handles 14 are connected to the fixing members 20. Therefore, when the fixing member 20 is fixed inside the through-hole 16 by the pressing member 22, the handle 14 connected to the fixing member 20 is fixed to the main surfaces 12 a and 12 b of the door plate 12. That is, the two handles 14 are fixed to the main surfaces 12a and 12b on the front and back of the door plate 12 independently of each other.

  The front and back surfaces of the door plate are generally referred to as “front surface” or “back surface”, but in the present invention, it is not necessary to clearly distinguish the front and back surfaces of the door plate. I will call it.

  According to the second aspect of the present invention, “the handle 64 disposed on at least one of the main surfaces 62 a and 62 b on the front and back of the door plate 62, and the concave shape provided on at least one of the main surfaces 62 a and 62 b of the door plate 62. A cylindrical fixing member 68 connected to the hole 66 and the handle 64 and inserted into the hole 66, and locked to the inside of the fixing member 68, and at least a part of the fixing member 68 is removed from the outside. It is a handle attachment structure 60 ”provided with a pressing member 70 that presses the outer surface of the fixing member 68 against the inner surface of the hole 66 by pushing it in the direction.

  In the present invention, a concave hole 66 is provided in at least one main surface 62 a, 62 b of the door plate 62, and a fixing member 68 is inserted into the hole 66. A handle 64 is connected to the fixing member 68. ing. Therefore, when the fixing member 68 is fixed inside the hole 66 by the pressing member 70, the handle 64 connected to the fixing member 68 is fixed to the main surfaces 62 a and 62 b of the door plate 62.

  According to a third aspect of the present invention, in the “handle attachment structure 10, 60” according to the first or second aspect, “a slit 52 extending in the axial direction is formed on the side wall of the fixing member 20, 68”. The inner diameter of at least a part of the fixing members 20, 68 is set so as to gradually decrease toward the back side. "

  In this invention, when the pressing members 22 and 70 are inserted into the fixing members 20 and 68, the pressing members 22 and 70 are pressed against the portion where the inner diameter is reduced, and the fixing members 20 and 68 are expanded in diameter. The outer surfaces of the fixing members 20 and 68 are pressed against the inner surface of the through hole 16 or the hole 66.

  According to a fourth aspect of the present invention, in the "handle attachment structure 10, 60" according to the third aspect of the invention, "a female screw 48 is formed on the inner surface of the fixing members 20, 68, and the pressing member A male screw 54 that is screwed into the female screw 48 is formed on the outer surfaces of the pins 22 and 70 ”.

  In the present invention, the pressing members 22 and 70 are locked inside the fixing members 20 and 68 by a screw structure.

  According to the fifth aspect of the present invention, in the “handle attachment structure 10, 60” according to any one of the first to fourth aspects, “a locking projection 50 is formed on the outer surface of the fixing members 20, 68”. It is formed ".

  In the present invention, the protrusions 50 formed on the outer surfaces of the fixing members 20 and 68 are locked to the inner surfaces of the through holes 16 or the holes 66.

  In the invention described in claims 1 to 5, the fixing members 20 and 68 are fixed inside the through-hole 16 or the hole 66 by the pressing members 22 and 70, and at the same time, the handles 14 connected to the fixing members 20 and 68, 64 is fixed to the main surfaces of the door plates 12 and 62. That is, even when the handles 14 and 64 are attached to both front and back main surfaces of the door plates 12 and 62, the front and back handles 14 and 64 are attached independently of each other. Therefore, when the thickness of the door plates 12 and 62 varies due to changes in temperature or humidity, the distance between the front and rear handles 14 and 64 can be made to follow the variation. It is possible to prevent the occurrence of “rattle”.

  Further, the through holes 16 or the holes 66 of the door plates 12 and 62 can be formed with high accuracy in advance in a factory. Therefore, in the field, it is only necessary to insert the fixing members 20 and 68 into the through holes 16 or the holes 66 and then lock the pressing members 22 and 70 inside the fixing members 20 and 68, so that the construction can be performed easily and reliably. .

A cylindrical fitting portion 40 that is rotatably fitted in the through hole 36 of the seat plate cover 28 is formed at the distal end portion of the base plate. A connecting rod 42 extending in the axial direction of the fitting portion 40 is formed at the distal end portion of the fitting portion 40 in one lever 30, and the rotation shaft 38 b and the fitting portion 40 in the other lever 30 are formed. Is formed with a hole 40a into which the tip of the connecting rod 42 is inserted. Further, a screw hole 44 is formed in the rotation shaft 38 b of the other lever 30, and a detachment prevention screw 46 is screwed into the screw hole 44. Accordingly, when the connecting rod 42 of one lever 30 is inserted into the hole 40a of the other lever 30, the two levers 30 are connected, and the disengagement prevention screw 46 is screwed into the screw hole 44. The withdrawal of is prevented.

  As described above, the seat plate through hole 16 is formed in the door plate 12, and the handle 14 is attached to the door plate 12 using the seat plate through hole 16.

  As shown in FIGS. 3 and 4, the fixing member 20 is a cylindrical member formed integrally with a seat plate 26 constituting the handle 14, and a female screw 48 is formed on the inner surface of the fixing member 20. A locking protrusion 50 is formed on the outer surface of the fixing member 20. Further, at least one slit 52 extending in the axial direction is formed on the side wall of the fixing member 20.

  The female screw 48 is a tapered female screw that is gradually reduced in diameter from the rear end to the front end of the fixing member 20, and the pressing member 22 is screwed into the female screw 48, thereby increasing the diameter of the fixing member 20. Is done.

  The protrusions 50 are annular protrusions extending in the circumferential direction of the fixing member 20, and in this embodiment, a plurality of protrusions 50 are disposed at intervals in the axial direction. Before the fixing member 20 is expanded, the outer diameter of the protrusion 50 is set to be approximately the same as or slightly smaller than the inner diameter of the through hole 16 for the seat plate. When the diameter is increased, the outer diameter of the protrusion 50 becomes larger than the inner diameter of the through hole 16 for the seat plate, and the protrusion 50 bites into the inner surface of the through hole 16 for the seat plate and is locked. In addition, the shape of the protrusion 50 may be a dot shape or a line shape in addition to the ring shape, and the number of the protrusions 50 may be appropriately increased or decreased as necessary.

  The slit 52 is a linear window formed to increase the diameter of the fixing member 20, and in this embodiment, the two slits 52 are arranged to face each other.

  As shown in FIGS. 3 and 4, the pressing member 22 is a cylindrical member that presses the outer surface of the fixing member 20 against the inner surface of the through hole 16 for the seat plate by pressing at least a part of the fixing member 20 outward. A male screw 54 is formed on the outer surface of the pressing member 22 and is screwed into a female screw 48 formed on the fixing member 20. A tool such as a screwdriver is provided at the rear end of the pressing member 22. A locking portion 55 for locking is formed.

  When configuring the handle attachment structure 10, as shown in FIG. 5, first, the fixing member 20 connected to the seat plate 26 is inserted into the through hole 16 for the seat plate of the door plate 12. The plate 26 is arranged on both main surfaces 12a and 12b on the front and back of the door plate 12. Subsequently, a male screw 54 formed on the outer surface of the pressing member 22 is screwed into a female screw 48 (FIGS. 3 and 4) formed on the inner surface of the fixing member 20, and the pressing member 22 is inserted into the fixing member 20.

The pressing member 22 may be locked to the fixing member 20 by the fitting structure. In this case, when the pressing member 22 is inserted into the fixing member 20, the protrusion 56 is pushed outward by the tip portion 58 a of the recess 58, and the fixing member 20 is elastically expanded in diameter. As the pressing member 22 is further inserted, the tip 58a of the recess 58 gets over the protrusion 56, and the protrusion 56 and the recess 58 are fitted.

  Further, in order to increase the diameter of the fixing member 20, it is only necessary to set the inner diameter of at least a part of the fixing member 20 to gradually decrease toward the back side so that the fixing member 20 can be pressed by the pressing member 22. . Therefore, when the fitting structure as shown in FIG. 6 is adopted, the inner diameter of the protrusion 56 is set to be gradually reduced toward the back side, and the protrusion 56 is pushed outward. Thus, the minimum outer diameter a of the recess 58 may be set larger than the minimum inner diameter b of the protrusion 56 (a> b) so that the fixing member 20 can be expanded in diameter.

  The fixing member 20 may be anything that is “connected” to the handle 14, and the “connection” mode is “the fixing member 20 and the handle 14 are integrally formed as in the above-described embodiment. In addition to the “mode”, the “mode in which the separately formed fixing member 20 and the handle 14 are engaged” and “the separately formed fixing member 20 and the handle 14 are joined (screw joining, adhesion, etc.).
