(A) is a cross-sectional view of one vertical frame of a door frame according to another embodiment, (b) is a horizontal cross-sectional view of one vertical frame of a door frame according to still another embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. First, schematic structure of the door frame 1 which concerns on several embodiment described below is demonstrated.

  The door frame 1 is a door frame in which a grip 12 is formed on the vertical frame 10. The grip 12 is formed on at least one of the front and rear ends of the vertical frame 10 in the viewing direction, and has a shape that protrudes toward the door frame opening 5 in the viewing direction.

  The door frame 1 has two vertical frames 10, 10 and an upper frame 2. Further, the door frame 1 may have the lower frame 3. The material of the door frame 1 is wood material, hard resin or the like.

  As an attachment aspect of this door frame 1, for example, as shown in the floor plan of FIG. 1 (a), an opening 33 for an entrance provided in a wall 32 of a washroom 30 of a general residence, a washroom 30 and a bathroom 31 Can be attached to the opening 33 provided in the partition wall 32 of the second embodiment.

  The door frame 1 (longitudinal frame 10) and the hanging outset sliding door 35 are attached to the entrance opening 33 (door frame opening 5), and movement between the washroom 30 and the outside is enabled. (See Fig. 1 (a) (b)). Further, the door frame 1 (longitudinal frame 10) and the two pulling doors 35 and 35 of the wrong-handed type for moving the rail 3a of the lower frame 3 are attached to the partition wall opening 33 (door frame opening 5) It is possible to move between the washroom 30 and the bathroom 31 (see FIGS. 1 (a) and (c)).

  As shown in FIG. 1 (b), a grip 12 is formed at the front end 10 a on the wash room 20 side in one of the two vertical frames 10, 10 provided in the entrance opening 33. Further, as shown in FIG. 1C, a grip 12 is formed at the front end 10a on the wash room 30 side in one of the two vertical frames 10, 10 provided in the partition wall opening 33. There is. Each of the grips 12 and 12 also protrudes to the door frame opening 5 and 5 side, and the protruding end is shaped to have rounded tops 14 and 14 as shown in the figure.

  These grips 12, 12 can be used as handrails. In each of the above two examples, the grip portion 12 is provided on the left vertical frame 10 when viewed from inside the washroom 30, so a person grips with the left hand facing the white arrow direction in FIGS. 1 (b) and 1 (c). It is convenient to use and easy to use. Of course you can also use it with your right hand. Moreover, the vertical frame 10 is constructed in a state where the front and rear ends slightly protrude from the wall surface, regardless of whether the vertical frame 10 has or does not have the grip portion 12. Therefore, the grip 12 can be used by putting a finger on the vicinity of the corner 12 a on the wall 32 side of the grip 12.

  As described above, the grip portion 12 may be formed on at least one of the front and rear ends of the vertical frame 10 in the viewing direction, that is, one vertical frame 10 may be provided at the rear end, and two front and rear It may be provided, and may be provided at a maximum of four places for one door frame opening 5.

  Next, the details of the vertical frame 10 having the gripping portion 12 will be described based on FIG. 2 and FIG. In these figures, the vertical frame 10 with the grip 12 provided in the partition wall opening 33 in FIG. 1 is illustrated.

  The grip portion 12 is formed at the front end portion 10 a of the vertical frame 10 in the direction of view as viewed from the washroom 30 side. As a cross-sectional shape of the vertical frame 10, a substantially triangular protrusion 13 is added to the door frame opening 5 side of the front end portion 10a of the vertical frame main body 11 having a rectangular cross section. The projecting portion 13 is disposed such that the acute-angled top portion 14 protrudes from the front end portion 10 a of the vertical frame 10 to the door frame opening 5 side.

  Since the top portion 14 of the grip portion 12 is used with fingers, it is desirable that the top portion 14 be formed in a curved shape with corners as shown in FIG. 2A and the like. In addition, since the corner 12a on the wall 32 side of the grip 12 may also be used with fingers, it is desirable to perform chamfering or the like (see FIG. 2A).

  The gripping portion 12 is disposed at the front end portion 10a of the vertical frame 10, and is generally a portion surrounded by an alternate long and short dash line in FIG. 1 (a). That is, the grip portion 12 in the present embodiment is configured by adding the protrusion 13 to the front end portion 10 a of the vertical frame 10, and the front end surface 15 thereof is a surface substantially parallel to the finding direction. Is an inclined surface, and has a cross-sectional shape having a concave top 14 in the projecting direction.

  When this grip 12 is used with the left hand, it can be used by putting the thumb on the top 14 and putting the palm on the front end face 15 or by putting a finger other than the thumb on the corner 12a on the wall 32 side Good (use by order). Also, it can be used by putting a finger other than the thumb on the top 14 and pointing the thumb downward or hanging it on the corner 12a on the wall 32 side (use by the hand). When the grip 12 is used with the right hand, the thumb may be put on the corner 12 a on the wall 32 side, and the other finger may be put on the top 14 for gripping.

  As described above, since the front end surface 15 of the grip 12 is formed flat and the grip 12 protrudes toward the door frame opening 5, the grip 12 can be easily grasped with fingers. Moreover, since the grip 12 does not protrude forward from the front end of the vertical frame 10, it does not have a feeling of pressure and it looks good. In particular, since the protruding portion 13 protruding toward the door frame opening 5 of the gripping portion 12 is substantially triangular, it is easy to hold the hand on the top portion 14 to hold it, it is simple and good in appearance, and easy to manufacture.

  Further, the grip portion 12 is not added so as to protrude to the front end side of the vertical frame 10, and the front end surface 15 of the grip portion 12 is matched with the end surface of the vertical frame 10 in the expected direction. That is, the grip 12 itself is assimilated to the vertical frame 10. Therefore, when viewed from the front, it is more visible to the thick vertical frame 10 than to the grip portion 12 (handrail), and there is no risk of impairing the design by the grip portion 12. In addition, the front side end surface 15 of the holding part 12 may be convexly curved. Further, on the front side end face 15, fine vertical grooves or the like for anti-slip or design may be formed.

  Further, as shown in FIG. 2B, the grip 12 is formed over substantially the entire length of the vertical frame 10 in the height direction. As shown in FIG. 2B, the grip 12 is cut off at the upper end of the vertical frame 10, and the upper frame 2 is assembled to the cut portion.

  As described above, since the grip 12 is formed in substantially the entire length in the height direction, it can be used for users of various heights, can be freely used, and is extremely convenient. It can also be used on wheelchairs. In the case of this example, the wheelchair can be easily pulled to the door frame opening 5 side by handling the grip 12 with the left hand as a reverse hand while riding on a wheelchair.

  Next, the detailed shape and dimensions of the gripping portion 12 will be described based on the partially enlarged cross-sectional view shown in FIG.

  The width dimension L1 of the front end surface 15 of the grip portion 12, that is, the end surface of the front end portion 10a of the vertical frame 10 in the direction of finding is preferably a size that can be easily grasped with one hand, preferably 35 to 60 mm. It is desirable to do. As described above, the width dimension L1 may be a numerical range of 20 to 90 mm because it can be used without holding it with the left hand and putting a finger on the top 14.

  Further, in the illustrated example, the thickness dimension L3 of the vertical frame main body 11 and the projection dimension L4 to the top portion 14 of the projection 13 are substantially the same. If the effective opening width of the door frame opening 5 is taken into consideration, it is desirable that the projecting dimension L4 be in a numerical range of 10 to 30 mm. If the projection dimension L4 is a numerical value of this degree, the projection dimension L4 is a projection degree that is sufficient for handling, and there is no risk of getting in the way of passing through the door frame opening 5.

  In addition, it is easy to use because the width dimension L1 is set to 35 to 60 mm, and the grip portion 12 with an angle of the top portion 14, that is, an angle θ formed by the front end face 15 and the back end face 16 is 25 to 40 degrees.

  A hearing survey was conducted with 4 prototypes with a width dimension L1 of 50 mm and an angle θ of 15 degrees, 30 degrees, 45 degrees, and 60 degrees. (The angle θ of 45 degrees and 15 degrees is shown in FIG. 5 (a)). There were many impressions that the one with 15 degrees had a strong sense of over-sharpness. In the case of the 45 ° and 60 ° ones, the grip was weak, and it was often felt that the hand was likely to hit the moving sliding door 35.

  In addition, interviews were conducted with three types of prototypes with the width dimension L1 of 50 mm and the radius of the top 14 being R5, R7.5, and R10, and the impressions were totaled. Met. R7.5 and R10 are too round and are slippery and difficult to use, and there are many impressions that the hand is likely to hit the moving sliding door 35 because the thickness is increased. The radius of the top 14 is preferably R3 to R5. In addition, since there is a possibility that fingers may be attached to the corner 12 a on the wall 32 side, the outer surface of the vertical frame 10 on the wall 32 side may be chamfered or rounded to the extent that it does not interfere with the fingers.

  Moreover, in order to prevent the fingers from coming into contact with the sliding door 35 moving toward the end facing surface 10b of the vertical frame 10, the separation dimension L5 with the sliding door 35 is 12 mm or more in consideration of the general size of the fingers. It is desirable to That is, the position of the base portion 16a of the rear end face 16 of the grip portion 12 is separated by 12 mm or more from the end position on the grip portion 12 side of the door end facing surface 10b of the vertical frame 10 when the sliding door 35 is closed. Is desirable. In addition, as for separation dimension L5, in order to improve safety, it is desirable to set it as 20 mm or more.

  In addition, as a mounting structure for the wall 32 of the vertical frame 10, the position of the front end surface 15 of the grip 12 in the prospective direction is 5 to 20 mm from the outer surface of the wall 32 to facilitate gripping the grip 12 as described above. (Dimension of L2 in FIG. 3) is preferably forward.

  Next, three examples of the shape of the gripping portion 12 (the front end portion 10a of the vertical frame 10) will be described based on the partial cross-sectional views shown in FIGS. 4 (a) to 4 (c).

  In the case of FIG. 4A, the angle of the top portion 14 is 45 degrees (the one with a two-dot chain line is 15 degrees). As in the above example, since the shape of the protrusion 13 protruding toward the door frame opening 5 is triangular, it is easy to grasp with fingers.

  As for the thing of FIG.4 (b), the protrusion shape of the protrusion part 13 of the holding part 12 is made into trapezoidal shape, and the upper bottom (bottom of the shorter one) is distribute | arranged to the back side end surface 16 side. With such a trapezoidal shape, the separation dimension L5 with respect to the sliding door 35 can be made large even if the angle θ is increased. In the case of using in the opposite hand, the fingers other than the thumb can be turned to the upper side, and the gripping portion 12 can be firmly gripped.

  In the case of FIG. 4C, the shape of the protrusion 13 of the grip 12 is a shape having a semicircular recess 13 a on the rear end surface 16. The recessed portion 13a is a finger hooking portion, and it is easy for the finger to be hooked in a forward or reverse manner.

  Although the door frame 1 for the sliding door 35 has been illustrated above, even if it is a door frame of an open door or a folding door, the gripping portion 12 substantially the same as that applied to the sliding door 35 can be applied. FIG. 5 (a) shows an example of the door 37, and FIG. 5 (b) shows an example of the folding door 38. As shown in FIG.

  FIG. 5A shows an example in which the vertical frame 10 on the door tip side of the open door 37 is provided with the grip 12. 10c in the figure is a door stop. The gripping portion 12 is provided at the end of the opening 37 in the direction opposite to the opening direction. Therefore, there is no possibility of coming into contact with the open door 37 that opens and closes, and the grip 12 can be used safely as a handrail. When the grip portion 12 is provided at the end of the vertical frame 10 in the direction in which the opening door 37 opens, the finger with the projection dimension of the protrusion 13 of the holding portion 12 hung on the holding portion 12 and the tip of the opening door 37 operated It may be set so as not to contact the side door end.

  Moreover, you may provide the holding part 12 in the vertical frame (not shown in Fig.5 (a)) of the door bottom side of the opening door 37. As shown in FIG. Also in this case, it is desirable to provide the grip 12 at the end of the opening 37 in the direction opposite to the opening direction.

  The thing of FIG.5 (b) is the example in which the vertical frame 10 of the folding door 38 used for partitions etc. was equipped with the holding part 12. As shown in FIG. The gripping portion 12 is provided at the end opposite to the direction in which the folding door 38 protrudes in the opening operation, and there is no risk of contact with the folding door 38 that opens and closes, and the gripping portion 12 can be safely used as a handrail it can. When the folding door 38 is provided with the gripping portion 12 at the end of the vertical frame 10 in the direction in which the folding door 38 projects in the opening operation, the protrusion dimension of the projecting portion 13 of the gripping portion 12 is It may be set to such an extent that it does not come in contact with the outside door surface of the protruding fold door 38.
