５の上半分の全部にががるので非常に大きな被圧迫力を
有し、これによって全体の構成が強固となって破損する
ことがなくなるものである。As described above, this invention is constructed by a door wheel consisting of a mounting frame 4 that pivotally supports a wheel 6, and a base frame 1 that rotatably holds this mounting frame 4 and is attached to a stile 9 of a fitting. A mounting frame 4 is formed in which holding portions 2 in a well-arc shape that open at the lower edges are cut out in both side walls of the frame 1, and side walls 11 are provided with an outer width that substantially matches the inner width of the base frame 1. On both side walls 11 of this mounting frame 4, a protruding part 5 is provided which has a substantially arc-shaped cross section with the same radius of curvature as the holding part, and the height from the chord of the protruding part 5 to the top of the arc is Since the length of the opening 3 of the holding part 2 is smaller than that of the holding part 2, the length of the opening 3 of the holding part 2 is smaller than the length of the opening 3 of the holding part 2.
The weight of the fittings, etc. applied to the structure is applied to the entire upper half of the protruding part 5 of the mounting frame 4 from the holding part 2, resulting in a very large pressure force, which strengthens the entire structure and may cause it to break. Things will disappear.
更に、車輪６部分が故障した場合に基枠１は建具に固定
したまま、車輪６と一体となった取付枠４を基枠１から
取外し、新規な取付枠４と交換すればよく、その交換に
際しても取付枠４を開口部３を通して容易に取外し、ま
た、新規な取付枠４を挿入し得るものである。Furthermore, if the wheel 6 part breaks down, the mounting frame 4 integrated with the wheel 6 can be removed from the base frame 1 while the base frame 1 is fixed to the fittings, and replaced with a new mounting frame 4. Even at this time, the mounting frame 4 can be easily removed through the opening 3, and a new mounting frame 4 can be inserted.
また、一方の突出部５の側壁と他方の突出部５の側壁と
の間隔を基枠１の外幅と略一致させるよう形成したから
、基枠１から突出部５が突出することもなく、建具のか
まち９の戸車取付部分を複雑に切欠形成する必要もなく
取付けが容易であるし、取付枠４の交換時の出し入れに
支承をきたすことがない。Furthermore, since the distance between the side wall of one protrusion 5 and the side wall of the other protrusion 5 is formed to substantially match the outer width of the base frame 1, the protrusion 5 does not protrude from the base frame 1. There is no need to form complicated notches in the door roller mounting portion of the stile 9 of the fittings, and the installation is easy, and there is no need to support the mounting frame 4 when it is inserted or removed when replacing it.
また、突出部５以外の取付枠４の両側壁１１は、突出部
５の優弧部分に連続した鍔状となるよう形成したから、
基枠１の保持部２部分に嵌入した取付枠４が車軸１０と
平行方向に引抜けることがない
更には、取付枠４の鍔状側壁１１には係止部１２を設け
、一方、前記基枠１の保持部２より外周部分に前記係止
部１２が係合する保合部１３を設けたがら、取付枠４を
基枠１の保持部２に嵌合して回動させたときに上記係止
部１２が基枠１の係合部１３に係止するため、その後は
取付枠４が基枠１に対して回動したり抜は落ちたりする
ことがなくなる。In addition, since the side walls 11 of the mounting frame 4 other than the protrusion 5 are formed in a brim shape that is continuous with the arched portion of the protrusion 5,
In order to prevent the mounting frame 4 fitted into the holding portion 2 portion of the base frame 1 from being pulled out in a direction parallel to the axle 10, a locking portion 12 is provided on the brim-shaped side wall 11 of the mounting frame 4, Although the retaining part 13 with which the locking part 12 engages is provided on the outer peripheral part of the holding part 2 of the frame 1, when the mounting frame 4 is fitted into the holding part 2 of the base frame 1 and rotated, the above-mentioned Since the locking portion 12 locks on the engagement portion 13 of the base frame 1, the mounting frame 4 will not rotate relative to the base frame 1 or fall off after that.
従って、基枠１と取付枠４とを組立てて機成した戸車が
、輸送時や保管時、或いはかまち９への取付時に分離し
てその取付枠４が脱落することがなくなるのである。Therefore, the door roller constructed by assembling the base frame 1 and the mounting frame 4 is prevented from being separated and the mounting frame 4 falling off during transportation, storage, or when being attached to the stile 9.
取付枠４の側壁１１の突出部５間には、突出部５の優弧
部分の曲率半径の中心を外れた位置で設けた車軸１０に
より取付枠４に車輪６を空転自在に取付け、前記基枠１
には保持部２の接線方向に押ねじ７を螺合し、取付枠４
には押ねじ７の先端が当接する被圧部８を設けたから、
押ねじ７によって被圧部８を圧迫すれば、車軸１０が保
持部２と突出部５の曲率半径の中心を外れた位置にある
ので、車軸１０即ち車軸６は順次降下するもので、結局
建具を持上げることになり、建具に対して車輪６の上下
の位置を調節することができるものである。Between the protrusions 5 of the side wall 11 of the attachment frame 4, a wheel 6 is attached to the attachment frame 4 so as to be freely rotatable by means of an axle 10 provided at a position off the center of the radius of curvature of the large arc portion of the protrusion 5. Frame 1
A set screw 7 is screwed in the tangential direction of the holding part 2 to attach the mounting frame 4.
Since the pressurized part 8 is provided with which the tip of the set screw 7 comes into contact,
When the pressurized part 8 is pressed by the set screw 7, the axle 10 is located at a position off the center of the radius of curvature of the holding part 2 and the protruding part 5, so the axle 10, that is, the axle 6, descends one after another, and eventually the fitting This allows the vertical position of the wheels 6 to be adjusted relative to the fittings.
以上説明したようにこの考案によれば、耐久性を向上さ

する車輪の高低を容易に加減できるばかりでなく取付枠
の交換も容易で、しかも、保管、運搬時等に基枠から取
付枠が脱落することもない等の実用上極めて有益な諸効
果が得られるものである。As explained above, this invention not only improves durability but also makes it easy to install, not only can the height of the wheel relative to the lower stile be easily adjusted, but also the mounting frame can be easily replaced. This provides extremely useful effects in practice, such as preventing the mounting frame from falling off the base frame during storage, transportation, etc.
