Description

  The present invention relates to a puller embedded in a recess formed at an end of a door surface such as a sliding door and used to open and close a sliding door by placing a finger, and in particular, between an adjacent door or a door pocket during operation. The present invention relates to a puller having a function of preventing a finger to be operated between the fingers.

  Conventionally, doors such as sliding doors have been provided with a finger to open and close the sliding door by placing fingers on it, and recently, the finger on the pulling hand during operation is between the adjacent door and the door pocket. What has the function to prevent pinching is known.

  By the way, as a means for preventing a finger from being pinched during the operation, a stopper provided with a stopper member (protector) protruding from the door surface is generally provided, but the stopper member protrudes forward from the door surface. What is necessary and always has a stopper function has been a nuisance or aesthetic problem when hitting the human body when passing nearby.

  Therefore, for example, in JP-A-2003-193711, JP-A-2003-232165, and JP-A-2004-150153, the stopper member is always arranged in a manner that does not protrude from the door surface, and only during operation. A stopper member that protrudes from the door surface and exhibits a finger pinching prevention function is proposed.

  However, the puller having the function of projecting the stopper member from the door surface and exhibiting the function of preventing finger pinching only at the time of the operation presented in the above-mentioned gazette is to act on the stopper member only when almost closed, A separate recess for inserting a finger when opening is required, and a stopper member is disposed beside the recess. Therefore, it becomes wide as a whole, and it is not only aesthetically excellent as a whole, but also the installation work becomes complicated and the material cost increases.

Further, in the conventional puller, the mechanism for extending and retracting the stopper member is complicated, and the ratio of the protrusion amount from the door surface to the lateral width of the stopper member is low, so that it is not possible to exert a sufficient finger pinching prevention function. In some cases.

  An object of the present invention is to solve the above-described problems with respect to a pulling handle installed in a sliding door, etc. The structure is not complicated and the width is not wide and is not only aesthetically superior, but also a stopper member. An object of the present invention is to provide an excellent puller that can sufficiently exhibit a stop function (finger pinching prevention function) with a large amount of protrusion from the door surface with respect to the width of the (protector).

  The present invention, which has been made to solve the above problems, includes a handle body embedded in a recessed portion formed at the end of a sliding door in a box shape having an opening on the front surface, and a stopper member built in the handle body. The stopper member has a shape in which the front surface is fitted to the opening edge of the front opening of the handle body, and the eccentric shafts are coaxially positioned at the opening side end of the sliding door on the top surface and the bottom surface, respectively. These eccentric shafts are respectively fitted and inserted into arc-shaped first guide grooves formed on the top wall and the bottom wall of the handle body that are opposed to each other, and are opposed to each other of the handle body. On the top wall and the bottom wall, there are guide shafts respectively fitted in second guide grooves extending substantially parallel to the front surface formed on the top surface and the bottom surface of the stopper member arranged opposite to each other. The It protrudes at the coaxial position in the vertical direction, and when the opening side end of the front surface of the stopper member is pressed, the eccentric shaft is closed to the first guide groove and the guide shaft is closed to the second guide groove. When the stopper member rotates by moving to the side end, the opening side end of the stopper member is pushed into the handle body and the closing side end of the stopper member protrudes from the opening of the handle body. Features.

  According to the present invention, the width of the stopper member can be formed not only by the same width as that of the handle having no conventional stopper member but also without a complicated structure. Even if it is not widened, the amount of protrusion from the door surface is large, and an excellent finger pinching prevention function can be exhibited.

  Further, in the present invention, when the eccentric shaft and the guide shaft are disposed so that the front surface of the stopper member is flush with the opening of the handle body, the positions in the front-rear direction are substantially equal. The sliding door opening side end portion of the first guide groove is in contact with the first guide pin, and the sliding door closing side end portion of the first guide groove and the protruding stopper member are provided. If the guide members are aligned with each other in the opening and closing direction, the stopper member can be positioned at a position where the front surface of the stopper member is along the opening of the handle body. A surface portion of the stopper member is disposed flush with the door surface and can be beautifully worn.

  Further, between the stopper member and the handle main body, the biasing means for returning the stopper member from the state in which the closed side end portion protrudes from the handle main body to the original state in which the front surface matches the opening of the handle main body. When the stopper member is always kept in a state where the surface of the stopper member is flush with the door surface, the appearance is kept beautiful, and the stopper member is rotated by operating the puller. In addition, when the finger pressing the stopper member is released, the stopper member automatically returns to its original state, so that an operation of returning it by hand is unnecessary.

  Furthermore, in the state where the front surface of the stopper member is orthogonal to the opening of the handle body in a state where the stopper member is rotated inside the handle body and the closed side end of the sliding door protrudes from the handle body. When a control member for preventing the rotation of the stopper member is provided, when the stopper member is pressed to close the end on the closed side and the sliding door is closed as it is, the stopper member Since the applied pressing force is transmitted to the sliding door via the control member rather than the first guide pin which is relatively difficult to withstand the pressing resistance, the pressing force applied to the stopper member is transmitted to the sliding door without loss, and the sliding door only travels reliably. In addition, since the first guide pin and the guide groove are not burdened, the damage can be prevented and the durability can be increased.

  According to the present invention, the structure is not complicated, and the lateral width is not wide and not only aesthetically pleasing, but also the amount of protrusion from the door surface with respect to the lateral width of the stopper member is large, and a finger pinching prevention function can be sufficiently exhibited.

  Next, embodiments of the present invention will be described below with reference to the drawings.

  The drawing shows a preferred embodiment of the present invention. As shown in FIG. 1, a puller 1 with a finger pinching prevention function according to the present invention is a door surface 21 of a sliding door 2 in the same manner as a conventional puller. Are used by being embedded in a recess 22 formed at the end.

  The pulling handle 1 according to the present embodiment is formed at an end portion of the door surface 21 of the sliding door 2 as shown in the perspective exploded view shown in FIG. 2, the perspective view shown in FIG. 3, and the plan view of FIG. The handle body 3 is embedded in the recessed portion 22 and the stopper member 4 is housed in the handle body 3 and exhibits a finger pinching prevention function.

  The handle body 3 has a vertically long hollow rectangular parallelepiped having an opening 31 on the front surface, and a flange 33 arranged along the door surface 21 of the sliding door 2 around the opening edge 32. In particular, the handle body 3 The width of 3 is formed in substantially the same manner as a conventional handle that does not have a finger pinching prevention function.

  The stopper member 4 has a substantially semicircular cross section having a front surface 41 having a shape fitted into an opening 31 formed on the front surface of the handle body 3, and the top surface 42 and the bottom surface 43 are formed on the sliding door 2. When attached, eccentric shafts 44, 44 project from the end in the opening direction so as to be coaxially opposed in the vertical direction, and the respective eccentric shafts 44, 44 are opposite top walls 34 of the handle body 3. And the first guide grooves 36, 36 formed in an arc shape so as to face the bottom wall 35, and face the top wall 34 and the bottom wall 35 facing each other of the handle body 3. Guide shafts 5 and 5 are respectively projected from the second guide grooves 45 and 45 formed on the top surface 42 and the bottom surface 43 of the stopper member 4 to be disposed. In this embodiment, when the front surface 41 of the stopper member 4 is flush with the opening 31 formed on the front surface of the handle body 3, the eccentric shaft 44 and the guide shaft 5 are moved back and forth. In the direction, an imaginary line connecting the eccentric shaft 44 and the guide shaft 5 is arranged at the same position, that is, parallel to the front surface 41 of the stopper member 4.

  Further, between the eccentric shaft 44 of the stopper member 4 and the side wall 37 of the opening side end of the handle body 3, the front surface 41 is connected to the handle body 3 from the state in which the closing side end protrudes from the handle body 3. An urging means 7 made of a tension coil spring for returning to the original state that is flush with the opening 31 is disposed.

  Furthermore, inside the handle main body 3, the front surface 41 of the stopper member 4 is opened in the opening 31 of the handle main body 3 in a state where the stopper member 4 is rotated and the closed end of the sliding door 2 protrudes from the handle main body 3. Is integrally provided with a control member 9 for preventing the stopper member 41 from rotating at a position orthogonal to.

  In the present embodiment, the guide shafts 5 and 5 are formed separately from the handle body 3, and are attached to the mounting holes 37 and 37 formed in the top wall 34 and the bottom wall 35 of the handle body 3. Manufacture is facilitated by adopting a structure that is inserted and fixed from above.

  The material of the handle body 3 and the stopper member 4 is not particularly limited, but is formed of a material conventionally used for a handle such as a hard synthetic resin, metal, or wood. Furthermore, in the present embodiment, the stopper member 4 is integrally molded. However, as shown in FIG. 5, the stopper member 4 is constituted by a hollow columnar main body 411, a plate-like top surface member 412, and a bottom surface member 413. In addition, a configuration in which the top surface member 412 and the bottom surface member 413 are fixed to the upper and lower end surfaces of the main body portion 411 is also possible. In this case, the stopper member 4 can be formed with a light weight and a small amount of material.

  As shown in FIG. 1, the pull handle 1 according to the present embodiment having the above-described configuration is used with a portion of the handle body 3 embedded in a recess 22 formed in the door surface 21 of the sliding door 2. It is inserted in the same manner as in the past, and is fixed by an adhesive, a nail, a screw or the like (not shown).

  And the pulling handle 1 attached to the sliding door 2 is normally the edge part of the opening side direction of the door of the 1st guide groove 36 whose eccentric shaft 44 of the stopper member 4 is circular arc shape by the urging | biasing action of the urging means 7. The guide shafts 5 projecting from the inner surfaces of the top wall 34 and the bottom wall 35 of the handle body 3 are in contact with the closed end of the door of the second guide groove 45 and are positioned respectively. As shown in FIGS. 2 and 5, the front surface 41 of the member 4 is arranged almost flush with the opening edge 32 of the handle body 3 so that the insertion recess of the finger is exposed like a conventional pulling handle. Not shown (not shown) and the appearance is very beautiful.

  To move the sliding door 2 shown in FIG. 1 in the opening direction using the handle 1, first, as shown in FIG. 6, with the abdomen 81 of the finger 8 facing the opening side of the sliding door, When pressing against the urging force of the urging means 7 in the direction perpendicular to the door surface 21 of the sliding door 2 shown in FIG. As shown in FIG. 8, the eccentric shaft 44 of the stopper member 4 is guided by the arc-shaped first guide groove 36 of the handle body 3, and the second guide groove 45 is guided by the guide shaft 5 of the handle body 3. Then, the stopper member 4 is rotated with a predetermined trajectory, and the pressing force indicated by the arrows B and C shown in the figure is applied to the stopper member 4, and the end of the stopper member 4 on the opening direction side is forward from the handle body 3. Protrusively.

  Further, when a pressing force is applied to the stopper member 4 with the finger 8, the stopper member 4 comes into contact with the control member 9 provided inside the handle body 3 as shown in FIGS. Is blocked.

  At this time, the control member 9 is set in advance at a position where the front surface 41 of the stopper member 4 is prevented from rotating at a position where the front surface 41 of the stopper member 4 is substantially orthogonal to the opening 31 of the handle body 3. The member 4 is prevented from rotating at a position substantially orthogonal to the opening 31.

  Accordingly, the pressing force is applied to the handle body 3 by applying a pressing force in the direction of the arrow D shown in the figure to the front surface 41 of the stopper member 4 which is substantially orthogonal to the opening 31 of the handle body 3 by the finger 8. (Not shown) is transferred in the opening direction.

  At this time, since the stopper member 4 protrudes from the handle body 3 nearly half of the width of the front surface 41, a sufficient protection effect, that is, an effect of preventing the hooked finger from being sandwiched between adjacent sliding doors or doors. In addition, the handle main body 3 is formed with a finger-hanging recess 38 near the half of the width of the front surface 41 of the remaining stopper member 4, so that the finger can be reliably hooked.

  Then, when the finger 8 is removed from the recess 38 with the sliding door 2 opened, the stopper member 4 is rotated in the opposite direction by the biasing means 7 to the original position shown in FIGS. Return automatically.

Furthermore, in order to move the sliding door 2 in the closing direction in the present embodiment,
As shown in FIG. 11, the finger 8 is inserted with the abdomen 81 facing the sliding door closing side, and the stopper member 4 is rotated by the back part 82 of the finger 8 in the same manner as in the case of opening the handle 8. The pressing force may be applied to the third side wall 37.

  Also in this case, when the finger 8 is released after the sliding door is opened, the stopper member 4 is returned to the original position by the biasing means 7.

  In the present embodiment, the stopper member 4 has a substantially semicircular cross section so that the stopper member 4 has a relatively wide width in the depth direction, so that the stopper member 4 can exert a sufficient strength when pressed with the finger 8. Or, there is no hindrance to rotation, and furthermore, it has the advantage that when it is rotated and projected with the operation of the sliding door, the appearance is beautiful and there is no risk of injury even if touched, but the stopper member 4 has a shape in which at least the front surface 41 is fitted into the opening 31 formed in the front surface of the handle body 3, and the eccentric shafts 44 and 44 are coaxially opposed to the top surface 42 and the bottom surface 43 in the vertical direction, respectively. What is necessary is just to be protrudingly provided, and another shape may be exhibited.
