[Industrial applications]

 The present invention is attached to a corner portion between a side pillar and a floor which are erected on the closed end side of a hanging door such as an automatic door, and guides the lower end of the door when the door is opened and closed. For the improvement of the floor guide used for.

[0002]

[Prior art]

 As is known, in the case of a suspended automatic door, the lower edge of the door is guided by an exposed guide rail laid on the floor along with an embedded guide rail embedded in the floor and a mat switch. However, there is a problem that the former guide rail is troublesome to install and the latter is downward when a switch mechanism other than the mat switch is used. Therefore, as schematically shown in FIG. 7, a base plate of a side pillar c provided upright on one side of the entrance / exit is provided with an upright standing plate b and a guide parallel erecting part b ′ for guiding the lower end of the door a. The floor guide d attached to the root has already been used. According to this, although it is easy to install and can be used when a switch mechanism other than the mat switch is used, the lower end of the door a is simply provided with a pair of upright plates bb. Therefore, when the door a swings at the time of opening and closing, the lower end abuts against the standing plate b and the guide collocation part b ′ and is damaged, and the door a is normally opened and closed. Not only the operation is hindered, but also the standing plate b slides on the door a, resulting in great wear.

For this reason, as already shown in FIG. 8, a flat plate portion e fixed to the floor surface of the floor guide d and a standing plate b standing upright from the flat plate portion e are integrally formed of metal. A slide contact plate f formed of a synthetic resin is prepared, and the slide contact plate f is attached to the surface of the standing plate b with a set screw g. Further, mohair or the like is attached to the surface of the slide contact plate f. The means for arranging the shock-absorbing sliding contact part h is adopted.

[0004]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional example, although the above-mentioned conventional defects are certainly improved, the buffer sliding contact portion h is worn out early by use, and the sliding plate f made of synthetic resin is then replaced with the door a. The sliding contact causes the sliding contact plate f to wear, and as a result, the set screw g and the door a contact each other, which damages the door a. Since the sliding contact plate f is exhausted and the door a comes into sliding contact with the metal standing plate b after that, the damage of the door a becomes great and an unpleasant noise is generated. .

The present invention has been made in view of the above problems. Instead of attaching a synthetic resin sliding contact plate to the standing plate with screws or the like, the door stop cover is attached and detached. By freely fitting the upright plate, the door-stop cover can be quickly replaced with a new one when it is consumed.

Further, according to claim 1, the door-contact cover is formed by a door-contact substrate portion and a sliding contact portion that is partially raised from the door-contact substrate portion, so that the door contact cover is in use during use. If it is visually confirmed that the sliding contact part has worn out and the raised sliding part has been exhausted, remove the sliding contact part from the standing plate by using a screwdriver, etc. The purpose of this is to make it possible to replace the suspended floor doors without delay, prevent accidental damage to the suspended floor doors, and prevent noise from occurring by simple replacement work. .

Next, according to a second aspect of the present invention, the sliding contact portion, which is a raised object of the door-stop cover, and the door-contact base plate portion are formed in different colors, so that the sliding portion is formed. The usage limit due to the wear of the door is made visible by the change in color, so that the trouble due to the delay in replacing the door stop cover can be more surely prevented.

In the third aspect of the present invention, the sliding contact portion of the door-stop cover is not raised from the door-contact base plate portion, but the door-contact base plate portion and the sliding contact portion are provided on the easily visible outer peripheral side wall of the door-stop cover. By forming a use limit display line that clearly indicates the boundary portion, the wear degree of the sliding contact portion can be constantly checked as in the case of claim 1 and claim 2, and the door cover can be replaced at appropriate times. , Trying to achieve the same purpose as above.

In the case of claim 4, the sliding contact portion of the door-contact cover is not raised from the door-contact substrate portion, but the door-contact substrate portion and the sliding contact portion of the door-contact cover are different in color. The wear limit of the sliding contact portion can be sensed by the use limit display line formed by the boundary between the two colors, so that the same object as in claims 1 to 3 can be achieved.

Further, in claim 5, as in the above-mentioned claims 1 to 4, only the use limit display line is provided by the door-contacting base plate part and the sliding contact part to achieve the above-mentioned purpose. Instead, the door stop cover is fitted to the standing plate, so that the standing plate is attached to the side pillar, so that not only the set screw that penetrates the mounting hole is shielded, but also the door is covered. The pair of lifting engaging grooves provided on the hit cover enables the door hit cover to be attached to and detached from the standing plate by simply moving it up and down. Further, at this time, with respect to the engaging part provided on the standing plate. By making it possible to detachably engage the engaged portion provided on the door-stop cover, the replacement work of the new door-stop cover can be facilitated and the door-stop cover can be unintentionally used. Its purpose is to prevent such a departure.

【Example】

 The present invention will be described in detail below with reference to an illustrated embodiment. In a hanging door as shown in FIG. 1 (A), a corner portion between the base portion of the side pillar and the floor surface. The flat plate portion 1a attached to the floor surface and the standing plate 1b bent upright from one end thereof and attached to the side pillar are formed into an L shape. The metal substrate 1 is provided.

On the flat plate portion 1a, a guide parallel portion 2 is provided so as to project upward with a door sandwiching gap G between the flat plate portion 1a and the standing plate 1b. Although it may be an upright plate, a guide roller 2a that is in rolling contact with a hanging door is used in the guide collateral portion 2 shown in the figure.

[0025] Here, if the guide parallelization part 2 illustrated above is briefly explained, as understood from Figs. 3, 4, and 6, the flat plate part 1a is attached to the floor surface by the attachment 1c. Holes 1d are elongated holes for adjustment, 1e is a screw for fixing, and 1f is a standing piece for fixing, and when the roller support plate 2b is placed on the flat plate portion 1a, its claw portion 2c has a flat portion of the flat plate portion 1a. It is slidably fitted in the adjusting long hole 1d, the long hole 2d is fitted in the fixing screw rod 1e, and the concave seat portion 2e is in the shaft column portion 2f of the guide roller 2a. The lower end head portion 2g of 2 is fitted as shown in FIG.

Further, the standing plate 1b is provided with a supporting projection 1m on the fitted plate portion 1h so as to press against the side pillar, and is attached to the standing plate 1b. In order to stabilize the state, there is also a fitted plate portion 1h on the lower side thereof, and in the illustrated example, a fitting portion 1n is formed by a protrusion, and the left and right sides of the fitted plate portions 1g, 1h are formed. Both side portions are portions that can be engaged with the door stop cover 3 as will be described later.

Next, the door stop cover 3 made of synthetic resin and having an appropriate elasticity will be described in detail. As clearly shown in FIG. 5, the door stop cover 3 is provided on both left and right sides of the door stop substrate portion 3a. An elevating engaging groove 3d is formed to face the fitted plate portions 1g and 1h of the installation plate 1b so as to be freely fitted, and further, the engagement portion formed on the upright plate 1b. A fitting portion 3e is provided which is elastically supported by 1n so as to be engageable with and disengageable from each other.

Here, in the door stop cover 3 according to claim 1, as shown in FIGS. 1 (A) and 1 (B), the guide is partially provided from the surface of the door contact substrate portion 3a. A sliding contact portion 3b is bulged toward the juxtaposed portion 2, and a use limit display line 3c is formed by a boundary portion due to a step between the door-stopping board portion 3a and the sliding contact portion 3b caused by this.

Therefore, when the above door stop cover 3 is used, the raised sliding contact portion 3b is in sliding contact with the hanging door and is worn away, so that the wear limit wears out and the use limit display line 3c disappears. After confirming the condition, you can replace it with a new one at any time. At this time, when removing the old door stop cover 3 from the standing plate 1b, insert the tip of the driver d into the gap between the flat plate portion 1a and the door stop cover 3 as illustrated in FIG. If the side is lifted, the engaged portion 3e can be easily separated from the engaged portion 1n.

Next, in the door-contact cover 3 according to claim 2, as shown in FIG. 1C, the raised sliding contact portion 3b and the door-contact substrate portion 3a have different colors. As described above, the use limit display line 3c as a step and the sharpness of the boundary due to the color difference are added as described above, and the wear of the sliding contact portion 3b can be clearly identified.

In the door-stop cover 3 according to the third aspect, as shown in FIG. 2A, the door-contact base plate portion is provided on the outer peripheral side wall of the door-stop cover 3 without protruding the sliding contact portion 3b. At the boundary between the sliding contact portion 3a and the sliding contact portion 3b, a mark is formed by means such as a groove, a ridge, or a line drawing, and this is used as a usage limit display line 3c. In this case also, the sliding contact portion 3b is reduced. The condition can be sufficiently monitored.

In the door-stop cover 3 according to the fourth aspect, as shown in FIG. 2B, the door-stop base plate portion 3a and the sliding contact portion 3b do not require any external addition means as a mark. The use limit display line 3c is the boundary portion formed only by differentiating between and, so that the wear state can be grasped by the change in color. It should be noted that the phantom line in the drawing indicates the cover 2j of the guide collocation section 2.
