Description

  TECHNICAL FIELD The present invention relates to a dropping bar receiver that is installed on the ground under a gate and is configured to receive a dropping bar of the gate.

  Many houses have gates as exterior doorways. Many of the gates have gate pillars and gates. The gate is provided to be rotatable or slidable with respect to the gate pillar. In order to keep this gate from moving, a dropping rod is often used. The dropping bar is attached to the gate, and the dropping bar is held by a cylindrical receiving member provided on the ground below the gate, thereby preventing the gate from moving.

  Here, since the dropping rod holder of the gate is fixed to the ground, it is difficult to remove even if dust accumulates in the hollow portion. Leaving the dust collected in the hollow part is not convenient because it not only deteriorates the exterior of the gate, but also reduces the function of the drop bar holder.

Therefore, among the prior arts, there is a gate lock receiving device configured to easily remove dust by appropriately removing the inner cylinder from the outer cylinder. (For example, refer to Patent Document 1).
JP-A-8-93367

  However, in the gate lock receiving device according to Patent Document 1, mortar work is involved in installation. In addition, there is a possibility that the dropping rod rattles against the inner cylinder. When the dropping rod rattles against the inner cylinder, there is a problem that an unpleasant sound is produced when the gate is shaken by wind or the like.

  An object of the present invention is to provide a gate drop bar holder that is easy to construct and easy to clean, and that can appropriately prevent rattling of the drop bar.

(1) The dropping bar support according to the present invention is configured to receive the dropping bar of the gate door while being installed under the gate. The dropping bar receiver includes a base member and a dropping bar guide member.

  The base member has a cylindrical shape having a hollow portion. Here, the meaning of the cylindrical shape includes a bottomed cylindrical shape. The base member functions properly even if it has a bottomed cylindrical shape. The base member is fixed to the ground. Further, the base member has a convex portion formed in a convex shape toward the inside at the upper portion of the inner peripheral portion.

  On the other hand, the drop rod guide member is made of a bottomed cylindrical soft material. A typical example of the soft material is elastomer. In addition, as a material for the drop rod guide member, rubber such as ethylene propylene diene rubber (EPDM) and chloropyrene rubber (CR), resin material such as polyethylene (LDPE, LLDPE, etc.) and ethylene vinyl acetate copolymer (EVA) May be used. The drop rod guide member is detachably attached to the hollow portion of the base member, and is configured to hold the drop rod at the inner peripheral portion. For example, by setting the inner diameter of the receiving member of the dropping rod so that the dropping rod fits snugly, or by providing a plurality of ribs in pressure contact with the dropping rod on the inner periphery of the dropping rod guide member The dropping rod is properly held around the circumference.

Moreover, it dropped rod guide member, the outer peripheral portion has thereby have the engaging portion configured to engage the convex portion of the inner periphery of the base member, a plurality of flange portions protruding outwardly It is. When a force with a finger or the like to the flange portion, in Rukoto be deformed dropped rod guide member, the convex portion and the second rib and the engagement is released, dropping the rod guide member tends detached from the base member Become.

  Since the base member has a cylindrical shape, the dropping bar support according to the present invention can be easily constructed with a drill and an adhesive. In other words, it is not necessary to carry out mortar construction. Moreover, since the dropping bar guide member can be removed from the base member, cleaning is easy. Furthermore, since the drop rod guide member that holds the drop rod is made of a soft material, even if the drop rod rattles against the drop rod guide member, the generation of unpleasant noise is suppressed by absorbing the impact. It is done.

(2) In addition, dropping the rod guide member have a flange portion around the opening, Rukoto is extended a flange portion from the flange portion is preferable. By applying a finger to the flange portion, it becomes easy to remove the dropped rod guide member from the base member, easily attached to the base member rod guide member off by applying a force to the flange portion.

(3) Moreover, it is preferable that a drop stick guide member is provided with the some 1st rib by which the taper part was formed upwards in the inner peripheral part. The reason is that the play of the dropping rod can be more reliably prevented by pressing the first rib against the dropping rod. In addition, the contact area between the inner peripheral portion of the drop bar guide member and the drop bar is reduced to reduce friction, so that the drop bar can be easily inserted into and removed from the drop bar guide member.

(4) Further, the engaging portion of the drop bar guide member is configured by a plurality of second ribs having tapered portions formed below, and the second ribs are respectively positioned at positions corresponding to the arrangement positions of the first ribs. Preferably they are arranged. Here, “arranged at the corresponding position” means that the first rib and the second rib are arranged on the same straight line extending in the radial direction of the drop bar guide member. However, slight deviation in the circumferential direction is allowed. Moreover, if there is a taper part in the 2nd rib, it will be easy to attach a drop stick guide member to a base member. In addition, the tapered portion creates a gap between the drop bar guide member and the base member, so that the drop bar guide member is easily deformed inside the base member.

  According to the dropping rod receiver of the present invention, construction is easy and cleaning is easy, and rattling of the dropping rod can be prevented appropriately.

  Hereinafter, the embodiment of the drop-rod holder for the gate of the present invention will be described with reference to FIGS. As shown in FIG. 1, the drop rod support 50 is installed in an installation hole 18 provided in the ground 16 located below the gate. The installation hole 18 is formed by a concrete drill or the like directly under the dropping rod 14 of the gate. The drop bar receiver 50 includes a base member 12 and a drop bar guide 10. In FIG. 1, for convenience of explanation, the base member 12 is shown protruding from the ground 16.

  As shown in FIGS. 2A to 2E, the base member 12 has a cylindrical shape. In the hollow portion of the base member 12, an internal space 125 for accommodating the drop rod guide 10 is formed. A convex portion 121 protruding toward the internal space 125 is formed on the inner peripheral portion of the base member 12. The base member 12 is inserted into the installation hole 18. The base member 12 inserted into the installation hole 18 is fixed in the installation hole 18 with an adhesive. In the present embodiment, polypropylene is used as the base member 12. However, the material of the base member is not limited to this, and other hard resin materials or metal materials (for example, aluminum) may be used.

  The drop rod guide 10 is made of a soft material such as an elastomer. As shown in FIGS. 3 (A) to 3 (E), the drop rod guide 10 has a bottomed cylindrical shape having an opening 105 on the upper side. The drop rod guide 10 includes three outer ribs 103 formed at equal intervals on the outer peripheral surface and three inner ribs 102 formed at equal intervals on the inner peripheral surface. In the present embodiment, the inner rib 102 corresponds to the first rib, and the outer rib 103 corresponds to the second rib. Each of the outer ribs 103 has a tapered portion 104 formed so that its height decreases toward the bottom. The tapered portion 104 is intended to make it easier to insert the drop bar guide 10 into the base member 12 and to make it easier for the peripheral wall of the drop bar guide 10 to bend outward in the base member 12.

  Each of the inner ribs 102 has a tapered portion 106 formed so that its height decreases upward. The inner ribs 102 are arranged at positions corresponding to the arrangement positions of the outer ribs 103, respectively. Further, the drop bar guide 10 includes a flange portion 101 around the opening portion 105. As shown in FIGS. 3C and 3D, the flange portion 101 is provided with three flange portions 107 at equal intervals. The flange portion 107 is configured to protrude from other portions of the flange portion 101. Further, the flange portion 107 is provided at a position corresponding to the position where the outer rib 103 is disposed.

  The operation of the base member 12 and the drop bar guide 10 when the drop bar 14 is inserted will be described with reference to FIGS. 4 (A) and 4 (B). As shown in FIG. 4A, when the drop bar guide 10 is attached to the base member 12, the outer rib 103 and the convex 121 are engaged with each other. Then, as shown in FIG. 4B, the drop bar 14 is inserted into the drop bar guide 10 from directly above. The dropping rod 14 abuts on the tapered portion 106 and enters the inside of the dropping rod guide 10 while expanding the peripheral wall of the dropping rod guide 10 to the outside.

  When the peripheral wall of the drop rod guide 10 is pushed outward by the drop rod 14, the outer rib 103 and the convex portion 121 are more strongly engaged. For this reason, it is difficult for the drop bar guide 10 to be detached from the base member 12 in a state where the drop bar 14 is inserted. For example, when the dropping rod 14 is pulled up from the dropping rod guide 10, the dropping rod receiving member 10 does not come off the base member 12 due to the action of the frictional force between the inner rib 102 and the dropping rod 14. In particular, if the convex portion 121 is disposed above the inner rib 102 as in the present embodiment, the dropping rod guide 10 comes out of the base member 12 when the dropping rod 14 is pulled up from the dropping rod guide 10. Can be reliably prevented.

  In addition, since the three inner ribs 102 and the drop bar 14 are in pressure contact with each other, the drop bar 14 is firmly held, so that the drop bar 14 does not rattle against the drop bar guide 10.

  On the other hand, the peripheral wall of the drop bar guide 10 that has been spread outward by the drop bar 14 returns to its original position due to elasticity when the drop bar 14 is removed. For this reason, the engagement strength between the outer rib 103 and the convex portion 121 is slightly weakened. As a result, the dropping rod guide 10 can be removed from the base member 12 with relative ease by placing a finger on the collar 107 and pulling up the dropping rod guide 10. For this reason, it becomes possible to easily remove the drop bar guide 10 and clean the inside.

  In addition, by preparing a plurality of variations of the drop bar guide 10 having different inner diameters, it is possible to deal with the drop bars 14 having different diameters.

  Further, as shown in FIG. 5, even if the position of the inner rib 102 is slightly shifted in the circumferential direction with respect to the positions of the outer rib 103 and the flange portion 107, the dropping bar guide 10 functions properly. For this reason, in the present invention, the outer rib 103 and the inner rib 102 should not be necessarily arranged on the same straight line along the radial direction of the drop bar guide 10.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
