Description

  The present invention relates to a shelf holder for attaching and supporting a shelf plate on a wall surface or the like.

  Conventionally, as shown in FIG. 8, the following Patent Document 1 includes a fixing member 51 attached to a mounting surface W such as a wall surface, and a moving member 52 that slides up and down with respect to the fixing member 51. In this example, a shelf board S is sandwiched and supported between the lower surface of the front protruding piece 53 at the upper portion of 51 and the upper surface of the bracket portion 54 of the moving member 52.

  The fixing member 51 is fixed to the attachment surface W by screwing the attachment screw 61 into the attachment surface W through the attachment through hole 55 in the intermediate portion, and the shelf board S is fixed by the fixing member 51 and the moving member 52. For clamping, the fastening screw 62 is screwed into the screw hole 57 below the fixing member 51 through the fastening through hole 56 below the moving member 52, and the moving member 52 is raised relative to the fixing member 51.

  Here, the mounting through hole 55 is a round hole corresponding to the screw diameter of the mounting screw 61. The fastening through hole 56 and the screw hole 57 have the same center and the distance to the reference surface facing the mounted surface W of the moving member 52 and the fixed member 51. Further, the tip of the tightening screw 62 bites into the shelf board S in order to prevent the shelf board S from slipping out between the fixed member 51 and the moving member 52.

  However, in the shelf holder as described above, when the fixing member 51 is fixed to the attachment surface W, the moving member 52 also strongly contacts the attachment surface W. Therefore, when the shelf board S is sandwiched, the moving member 52 and the attachment member are attached. There is a problem that it is difficult to slide the moving member 52 with respect to the fixed member 51 by rotating the fastening screw 62 due to friction with the surface W.

  As a countermeasure, if the moving member 52 is set to rise in a state of being separated from the attached surface W, the gap remains between the moving member 52 and the attached surface W even in the state after the construction. There arises a problem that the stability and aesthetics of the shelf board S are impaired.

  Further, when the shelf board S is made of glass, there is a problem that a method of preventing the shelf board S from being pulled out by biting the tip of the fastening screw 62 into the shelf board S cannot be adopted.

  In addition, when the shelf board S is supported by a plurality of shelf holders, even if an attempt is made to finely adjust the attachment height of the fixing member 51 in order to level the shelf board S, the screwing position of the attachment screw 61 is not changed. There is a problem that it is impossible.

  Further, in order to enable this fine adjustment, if the mounting through hole 55 is a normal elongated hole extending in the vertical direction, the mounting screw 61 is positioned below the mounting through hole 55 and the fixing member 51 is at a high position. In this state, when the mounting screw 61 is slightly loosened, the fixing member 51 falls to the lower end within the range of the mounting through hole 55 with respect to the mounting screw 61, resulting in a problem that the operation is difficult to perform.

  Then, this invention makes it a subject to make it possible to attach a shelf board to a to-be-attached surface easily and reliably in the construction state excellent in aesthetics.

  In order to solve the above-described problems, the present invention includes a fixing member that is fixed by screwing a mounting screw into a mounting surface such as a wall through a mounting through hole, and a moving member that slides up and down relative to the fixing member. The fastening screw is screwed into the screw hole of the fixing member through the through hole for fastening of the moving member, the moving member is raised with respect to the fixing member, and the shelf board is sandwiched between the fixing member and the moving member. In the shelf holder, the distance from the reference surface facing the mounting surface of the moving member to the center of the through hole for fastening is larger than the distance from the reference surface facing the mounting surface of the fixing member to the center of the screw hole. When the tightening screw is screwed into the screw hole with the moving member away from the mounting surface, the countersunk part formed around the taper surface of the head of the tightening screw and the through hole for tightening The taper surfaces of the Than it was into close contact Te.

  Also, a recess is provided on the upper surface of the moving member, and a protrusion protruding from the lower surface of the shelf engages with the recess, or a protrusion rising from the bottom of the recess engages with the locking hole of the shelf. Thus, the shelf plate is prevented from coming out between the fixed member and the moving member.

  Furthermore, the mounting through hole of the fixing member is formed in a tapered shape that is long and vertically narrowed, and according to the amount of looseness of the mounting screw, the taper surface of the head of the mounting screw that is a countersunk screw and the mounting through hole Even if the mounting screw is slightly loosened in the state where the contact position with the tapered surface of the countersink formed around changes, the mounting screw is located in the lower part of the through hole for mounting and the fixing member is at a high position The fixing member is prevented from dropping to the lower end within the range of the mounting through hole with respect to the mounting screw.

  In the shelf holder according to the present invention, when the fastening screw is screwed into the fixing member due to the shift of the center of the screw hole of the fixing member and the through hole for fastening of the moving member and the sliding of the tapered surfaces, the moving member is attached. Since it is drawn close to the surface and in close contact with it, it can be prevented from opening a gap between the moving member and the surface to be mounted after construction. It is excellent, and the stability of the shelf board when a heavy object is placed on the shelf board is also improved.

  In addition, in the case where the upper surface of the moving member is provided with a recess, when the shelf board is made of wood, a protrusion such as a wood screw screwed into the shelf board is engaged with the recess of the moving member, and the shelf board is made of glass. In some cases, a protrusion such as a tapping screw that rises from the bottom of the recess can be engaged with a locking hole formed in the shelf board to prevent the shelf board from slipping out.

  In addition, in the case where the through hole for mounting the fixing member has a tapered shape, the mounting height of the fixing member can be easily lowered and gradually adjusted by loosening the mounting screw. Can be easily mounted horizontally.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the shelf holder is configured to attach and support a shelf board S to a mounting surface W such as a wall, a fixing member 1 fixed to the mounting surface W, and a fixing member 1. The moving member 2 slides up and down.

  As shown in FIGS. 2 and 3, the fixed member 1 includes a fixed body 3 made of metal such as zinc alloy and a pad 4 made of resin, and the moving member 2 is made of a movable body 5 made of metal such as zinc alloy. And a pad 6 made of resin.

  The pad 4 of the fixed member 1 is attached to the lower surface of the front protruding piece 3b extending forward from the upper portion of the trunk 3a of the fixed main body 3, and the pad 6 of the moving member 2 is attached to the upper surface of the bracket-shaped moving main body 5. Yes.

  Guide portions 3 c are provided on both sides of the trunk portion 3 a of the fixed main body 3, and the guide portions 3 c are inserted into vertical grooves 5 a formed on the inner surfaces of both sides of the movable main body 5 so as to be slidable in the vertical direction. The width of the vertical groove 5a is larger than the width of the guide portion 3c, and the fixed member 1 and the moving member 2 are engaged with each other with play in the front-rear direction.

  In the middle part of the trunk portion 3a, a mounting through-hole 7 which is long in the vertical direction and has a tapered shape is formed so as to penetrate in the front-rear direction. It is provided so that it may penetrate.

  The diameter of the lower part of the mounting through-hole 7 is larger than the mounting screw 21 described later, and the diameter of the upper part is a size corresponding to the mounting screw 21. A countersunk portion 7 a is formed around the mounting through hole 7, and a counterbore 8 a is formed around the positioning through hole 8.

  A screw frame portion 3d protrudes from the lower front surface of the trunk portion 3a, and a screw hole 9 whose axis is directed in the vertical direction is provided in the screw frame portion 3d. A tightening screw 22 described later is screwed into the screw hole 9.

  A round hole tightening through hole 10 is provided in the lower part of the moving body 5 so as to penetrate vertically. The diameter of the tightening through hole 10 is larger than the diameter of the screw hole 9. Around the through hole 10 for tightening, a dish fir portion 10 a is formed on the bottom surface side of the movable body 5.

  The pad 6 has a recess 11 on the upper surface, and a notch through which the screw frame 3d of the fixed body 3 passes at the rear. The pad 4 is provided with a relief hole 4 a located above the recess 11.

  In order to attach the shelf S to the attachment surface W using such a shelf holder, first, as shown in FIG. 4, the attachment screws 21 are screwed into the attachment surface W through the attachment through holes 7. The fixing member 1 is fixed to the mounting surface W. As the mounting screw 21, a countersunk wood screw is used for the head 21 a.

  At this time, the mounting screw 21 is positioned below the mounting through-hole 7, and the fixing member 1 is set at a high position in the initial state.

  Thereby, when it is desired to change the mounting height of the fixing member 1, if the mounting screw 21 is slightly loosened, the taper surface of the head 21 a of the mounting screw 21 and the taper surface of the countersunk portion 7 a according to the amount of looseness. The contact position changes, and the fixing member 1 does not fall to the lower end within the range of the mounting through-hole 7 with respect to the mounting screw 21, and the mounting height of the fixing member 1 can be easily lowered and gradually adjusted.

  In addition, a cross-shaped mark may be recorded in advance on the mounting surface W, and this may be matched with two sets of diagonals of the positioning through-hole 8 having a rhombus shape.

  Further, after finely adjusting the mounting height of the fixing member 1, a wood screw may be screwed into the mounting surface W through the positioning through hole 8 so that the fixing member 1 is securely fixed.

  Then, as shown in FIG. 5, the moving member 2 is fitted to the fixing member 1 from below, and the fastening screw 22 is screwed into the screw hole 9 through the fastening through hole 10, thereby fixing the fixing member 1. The moving member 2 is raised, and the shelf board S is sandwiched between the pad 4 of the fixed member 1 and the pad 6 of the moving member 2. As the tightening screw 22, a countersunk bolt is used for the head 22 a.

  At this time, as described above, the diameter of the through hole 10 for tightening is larger than the diameter of the screw hole 9, and the fixing member 1 and the moving member 2 are engaged with play in the front-rear direction. Until the head portion 22a of the attachment screw 22 enters the countersunk portion 10a of the through hole 10 for tightening, the moving member 2 is moved away from the attachment surface W without receiving the resistance of the attachment surface W. Can be made.

Further, as shown in FIG. 6, the distance L ₁ from the reference surface facing the mounting surface W of the fixing member 1 to the center of the screw hole 9 is larger than the reference surface facing the mounting surface W of the moving member 2. distance L ₂ to the center for Nukiana 10 tightening is set larger.

  For this reason, when the tightening screw 22 is further screwed in, the taper surface of the head portion 22a of the tightening screw 22 and the taper surface of the countersunk portion 10a slide relative to each other, and the moving member 2 is attracted to the mounting surface W. It will adhere | attach and can prevent a clearance gap opening between the moving member 2 and the to-be-attached surface W in the state after construction.

  In addition, when the shelf board S is made of wood, a projection 23 such as a wood screw is screwed into the lower surface of the shelf board S so that the head projects, and the projection 23 is inserted into the recess 11 of the moving member 2. When engaged, the shelf board S can be prevented from coming out from between the fixed member 1 and the moving member 2.

  At this time, even if the tip of the protrusion 23 protrudes from the top surface of the shelf S, if the protrusion amount is equal to or less than the thickness of the pad 4, the collision of the tip of the protrusion 23 with the fixed main body 3 is a relief hole. It can be avoided by 4a.

  Further, when the shelf board S is made of glass, as shown in FIG. 7, a projection 24 such as a tapping screw is screwed into a pilot hole 11 a formed in the bottom of the recess 11 to stand up. When 24 is engaged with a locking hole 25 formed in the shelf plate S, the shelf plate S can be prevented from coming out from between the fixed member 1 and the moving member 2.
