JP7041553B2 - Arc-shaped door device for booth - Google Patents

Description

The present invention relates to the technical field of an arcuate door device for a booth to be built at the entrance / exit of a partitioned (partitioned) booth (room) such as a toilet booth or a shower booth.

Today, a so-called arc-shaped door that opens and closes the doorway by sliding the arc-shaped door body in the left-right direction along the arc trajectory as a door device built at the doorway of a partitioned booth such as a toilet booth. A device has been proposed. Since such an arcuate door device can be pulled into the booth room when the doorway is opened, the left and right width of the doorway is wider than in the case of a normal left / right sliding door device. However, there is an advantage that the left and right width of the booth can be made smaller. In this case, in a sliding door device that moves linearly to the left and right, an attempt is made to reduce the generation of noise and vibration (impact) by avoiding a shocking stop of the door when the door is opened or closed. This also applies to the door body of the arcuate door device.
Therefore, an arcuate door device has been proposed in which a braking member is provided to provide braking to a door body that opens and closes to cushion a shocking stop (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-337013

However, the conventional braking member is made of an elastic material having rubbery elasticity so as to be elastically deformed, and a hanger roller that is opening and closing moves to compress and deform the braking member to apply braking, for example. If this is provided at the end of the suspension rail on the door tail side to cushion the impact when the door is opened, on the contrary, this acts as a resistance when opening the door, and smooth opening operation is performed. There is a problem that the problem is impaired, and here is a problem to be solved by the present invention.

The present invention has been created for the purpose of solving these problems in view of the above circumstances, and the invention of claim 1 is for a booth for opening and closing an entrance / exit arranged in the front part of the booth. In the arc-shaped door device, the arc-shaped door device is arranged so as to extend from the upper part of the doorway to the upper part of the booth and provided at the upper end portion of the door body. Equipped with an arc-shaped suspension rail that guides the hanger roller to move in a state of drawing an arc trajectory, and in a buffered state where braking is applied to the door body that opens and closes in an arc trajectory at the stop end of the door body of the suspension rail. In providing the cushioning member for stopping, the cushioning member is a cylinder type that applies braking by the rod moving backward in a linear direction with respect to the cylinder in response to the contact of the door body with the tip of the rod. The cushioning member is arranged so that the retracting direction of the rod is substantially along the tangent line of the arc locus of the door body, and is between the hanger roller rolling surface of the suspension rail and the upper end edge portion of the door body. It is an arcuate door device for booths, which is characterized by being arranged.
According to the second aspect of the present invention, the cushioning member is arranged on the suspension rail side in a state where the rod tip portion is located at the arc locus position of the door body and the cylinder rear end portion is located outside the arc locus. The arcuate door device for a booth according to claim 1 .
The invention of claim 3 is an arc-shaped door device for a booth for opening and closing an entrance / exit arranged in the front part of the booth, wherein the arc-shaped door device is an arc-shaped door body that slides to open / close the entrance / exit. , It is arranged from the upper part of the doorway to the upper part of the booth, and is equipped with an arc-shaped suspension rail that guides the hanger roller provided at the upper end of the door body to move in a state of drawing an arc trajectory. In providing a cushioning member at a site for stopping the door body that moves open and close by drawing an arc locus in a cushioning state in which braking is applied, the cushioning member receives the contact of the door body with the tip of the rod. The rod is of a cylinder type that applies braking by moving backward in a linear direction with respect to the cylinder, and the cushioning member has such that the retracting direction of the rod substantially follows the tangent line of the arc locus of the door body. For booths, the suspension rail is further provided with a stop member that is elastically contacted at a position immediately before the door body that is being damped by the cushioning member stops and receives the door body stop . Arc-shaped door device.
The invention according to claim 4 is the arcuate door device for a booth according to claim 3 , wherein the cushioning member and the stop member are attached to a suspension rail via a common bracket.

According to the invention of claim 1, in an arcuate door device for a booth provided with an arcuate door and a suspension rail, when the door is stopped, the movement of the door is damped to give a shocking stop. Since the cushioning member provided for cushioning the rod is of a cylinder type in which the rod moves backward with respect to the cylinder in response to the contact of the door body with the tip of the rod, braking is applied. Although it is possible to smoothly open and close the door without causing resistance when opening and closing the door, the retracting direction of the rod when braking the movement of the door is the arc of the door. As a result of the direction substantially along the tangential line of the locus, braking is applied in a state where the door body moving along the arc locus is linearly received from the arc locus toward the tangential direction, and the braking efficiency is improved. Well, it is possible to make a reasonable buffer stop of the door body that moves in an arc locus. Moreover, as a result of the cushioning member being arranged between the hanger roller rolling surface of the suspension rail and the upper end edge of the door body, the cushioning member is displaced from the hanger roller rolling surface along the arc locus of the suspension rail. The arrangement of the cushioning member can be freely set without being bound by the rolling surface of the hanger roller.
According to the second aspect of the present invention, the cushioning member is arranged along the tangent line of the arc locus with the rod tip portion located at the arc locus position and the cylinder rear end portion located outside the arc locus. As a result, the door body that draws an arc locus and operates to open receives the braking received along the tangential direction of the arc locus at the initial position where it abuts on the rod tip and begins to receive braking. As a result, the cushioning by the efficient cushioning member can be received, and it is possible to greatly reduce the generation of impact and noise when the door body is stopped in the fully opened state.
According to the invention of claim 3 , in an arcuate door device for a booth provided with an arcuate door and a suspension rail, when the door is stopped, the movement of the door is damped to give a shocking stop. Since the cushioning member provided for cushioning the rod is of a cylinder type in which the rod moves backward with respect to the cylinder in response to the contact of the door body with the tip of the rod, braking is applied. Although it is possible to smoothly open and close the door without causing resistance when opening and closing the door, the retracting direction of the rod when braking the movement of the door is the arc of the door. As a result of the direction substantially along the tangential line of the locus, braking is applied in a state where the door body moving along the arc locus is linearly received from the arc locus toward the tangential direction, and the braking efficiency is improved. Well, it is possible to make a reasonable buffer stop of the door body that moves in an arc locus. Moreover , when the door body is stopped, in addition to the braking cushioning by the cushioning member, the stop receiving by the stop member is performed immediately before the stop, so that the shocking stop of the door body can be more reliably eliminated. It is possible to further reduce the impact and noise generation at the time of stopping.
According to the invention of claim 4 , although the cushioning member and the stop member are provided, these are provided on the suspension rail via one common bracket, so that the number of parts can be reduced. , Workability is improved.

In the present embodiment, the toilet booths 1 are adjacent to the left and right, and in this case, the intermediate door end side and the door tail side provided at the tip of the side panel body 4 that partitions the adjacent toilet booths 1. The front panel bodies 2 and 3 are configured to be continuous on the left and right, and the front panel bodies 2 and 3 on the end side are configured to be different from each other. Further, in the present embodiment, the left side surface of the left side toilet booth 1 in FIG. 2 is formed not by the side panel 4 but by the skeleton surface W such as a wall, but these configurations can be appropriately implemented if necessary. Needless to say, it is.

Reference numeral 5 denotes a door body having an arc shape in a plan view, and the door body 5 is provided with a hanger roller (suspension roller) 6 in a state of protruding upward from the bracket 6a provided at the left and right upper end edges of the door body 5. However, the suspension rail (hanger rail, guide rail) 7 to be moved and guided by the hanger roller 6 rolling has an arc shape so as to follow the arc shape of the door body 5, and is above the doorway E and the toilet. It is arranged so as to extend to the upper end portion of the side panel 4 on one side (door tail side) in the left-right direction when entering the booth 1. Incidentally, the suspension rail 7 of the present embodiment is provided on the bracket 7a provided on the front panel body 2 on the door end side, the bracket 7b provided on the front panel body 3 on the door tail side, and the side panel body 4 (or the skeleton surface W). It is attached by being fastened to a pair of front and rear brackets 7c and 7d. Then, when the hanger roller 6 rolls the suspension rail 7 in the horizontal direction, the door body 5 slides in the left-right direction to close the doorway E, and the door tail side side panel body of the toilet booth 1 is closed. It is transformed into an open posture in which the doorway E is opened (opened) by entering the toilet booth 1 on the 4th side.

In the toilet booth 1, when the door body 5 is closed, the door stop 8 that the door end side edge portion of the door body 5 abuts and receives, and the guide groove (track) 5a formed at the lower end edge portion of the door body 5 The guide body (guide roller) 9 provided on the front panel body 3 on the door tail side via the bracket 9a to guide the opening and closing of the door body 5 by being fitted (engaged) into the door body 5, and the impact when the door body 5 is fully opened. A cushioning member 10 to be described later is provided at the end of the suspension rail 7 on the door tail side to cushion the suspension rail 7. Needless to say, the cushioning member 10 may be provided on the door end side if necessary.

The door stop 8 is fixed via the screw 8b in a state where the front surface of the base portion 8a is in surface contact with the booth indoor side surface 2a of the front panel body 2 on the door end side, and the door stop 8 is fixed from the base portion 8a. The hollow contact side portion 8d on which the door contact surface 8c with which the end end portion on the door end side of the closed door body 5 abuts is formed is extended.
In the figure, S is a closing plate that closes the front side portion between the suspension rail 6 and the door body 5, 11 is a handle provided on the door body 5, 12 is a locking operation tool provided on the door body 5, and T is. It is a toilet bowl provided in the toilet booth 1.

The cushioning member 10 is of a cylinder type (piston-cylinder type) including a cylindrical cylinder 10a and a rod (piston rod) 10b that moves back and forth in a linear direction with respect to the cylinder 10a. In the present embodiment, a hydraulic type rod 10b having a short range (length, distance) of advancing / retreating movement (for example, 10 mm) is adopted.

The suspension rail 7 is formed with a rolling surface portion 7e on which the hanger roller 6 rolls on the upper surface at the lower end portion with a gap in the front-rear direction, and the hanger roller 6 rolls above the rolling surface portion 7e. An upper side portion (ceiling side portion) 7f connected in a series in the front-rear direction is provided via a space R, and the upper side portion 13a of the bracket 13 for attaching the cushioning member 10 is on the lower side of the upper side portion 7f. It is fixed via the screw 13b in a state of being in contact with the hanger.

The bracket 13 is provided with a support side portion 13c that hangs down from the door end side end edge portion of the upper side portion 13a in a rolling space R, and rolls on the lower end edge portion of the support side portion 13c. A penetrating side portion 13d that penetrates the gap between the moving surface portions 7e in a loose-fitting manner is provided, and extends from the lower end edge portion of the penetrating side portion 13d to the door tail side in a state of being in contact with the lower end surface of the rolling surface portion 7e. The provided lower side portion 13e is provided, and the lower side portion 13e is fixed to the rolling surface portion 7e via the screw 13f. Further, a mounting side portion 13g extending downward is provided from the door tail side end edge portion of the lower side portion 13e. The door end side portion of the cylinder 10a is fixed to the mounting side portion 13g, and the cushioning member 10 mounted in this way has a rolling surface portion 7e and a door body 5 at the door tail side portion of the suspension rail 7. It is configured to be arranged in the cushioning member arrangement space U between the upper end edge portion of the cylinder.

On the other hand, an L-shaped abutting body 14 is abutted from the upper surface side of the bracket 6a for attaching the hanger roller 6 to the door body 5, and is fixed to the door body 5 together with the bracket 6a via the screw 14a. However, the contact body 14 is provided with an upright contact side 14b located in the cushioning member arrangement space U. Then, when the door body 5 in the closing movement process reaches a position slightly before the fully closed position, the contact side 14b abuts on the tip portion 10c of the rod 10b (see FIGS. 6, 8A and 8B). The cushioning member 10 receives the inertial force at this time, and the rod 10b starts to move backward with respect to the cylinder 10a and starts to receive braking. However, in the initial state of contact, the hanger roller 6 is pressed. The end of the roller support 6b to be supported is separated from (not in contact with) the stop member (stop receiving member) 15 having rubber elasticity provided in the support piece portion 13c of the bracket 13. There is.

Then, in the intermediate process in which the door body 5 moves to the fully closed position side (see FIGS. 9A and 9B), the contact side of the roller support 6b is maintained in a state of being separated from the stop member 15. The 14b continues to move the rod 10b backward and receives further braking, but when the door body 5 reaches the position immediately before the stop, the roller support 6b comes into contact with the stop member 15. The door body 5 is stopped in a state of further receiving elastic braking (buffering) (see FIGS. 10A and 10B).

In this way, when the door body 5 moving along the arc locus X is stopped, the door body 5 is braked by the cushioning member 10 in which the contact side 14b abuts on the rod 10b and is moved backward. Although it will stop in a cushioned state, in the case where the present invention is carried out, the arrangement of the cushioning member 10 with respect to the suspension rail 7 is as follows.

That is, in the present embodiment, at the time when the door body 5 comes into contact with the cushioning member 10, specifically, at the position Z where the contact piece 14b on the door body 5 side comes into contact with the rod tip portion 10c of the cushioning member 10. , The receding direction (length direction, moving direction of the rod 10b) Y of the rod 10b coincides with the tangential direction (direction orthogonal to the radius line (direction) V) of the arc locus X at the corresponding tangential position Z. As a result, the cushioning member 10 has an arrangement configuration in which the rear end portion 10d on the door tail side of the cylinder 10a is located outside the arc locus X and is disengaged. Is arranged in the cushioning member arrangement space U between the rolling surface portion 7e of the suspension rail 7 and the upper end edge portion of the door body 5, and therefore interferes with the rolling space R of the suspension rail 7 when viewed from the bottom. Even if it is a thing, it is configured so that it can be arranged without any problem.

In the present embodiment configured as described above, the door body 5 is guided between the doorway E and the part of the toilet booth 1 on the door tail side while being guided by the arcuate suspension rail 7. The doorway E is opened and closed by sliding left and right, but when the door body 5 is opened, the end edge of the door body 5 on the door tail side is in a buffered state where it comes into contact with the cushioning member 10 and receives braking. It will stop, and the impact and noise at the time of stop will be regulated.

In this case, as described above, at the initial contact position Z of the contact side 14b on the door body 5 side with the rod tip portion 10c, the receding direction Y of the rod 10b is the arc locus X at the corresponding contact position Z. As a result of matching the tangential direction, the cushioning member 10 receives the door body 5 moving in the arc locus X in the most efficient state and applies braking, so that the door body 5 is stopped. Time can be buffered reliably in an efficient state.
With such an arrangement, the cushioning member 10 has a rear end portion on the door tail side located outside the arc locus X, and the rolling space R of the hanger roller 6 provided on the suspension rail 7 is provided. The cushioning member 10 is arranged in the cushioning member arrangement space U between the rolling surface portion 7e of the suspension rail 7 and the upper end edge portion of the door body 5, although the arrangement may interfere with the bottom view. Therefore, it can be arranged without any problem.

Further, when the present invention is carried out, in the present embodiment, the receding direction Y of the rod 10b is the arc locus X at the corresponding tangential position Z at the initial contact position Z of the contact side 14b with the rod tip portion 10c. However, the direction is not limited to this, and the receding direction Y of the rod 10b and the tangential direction of the arc locus X are provided in any of the receding movement ranges P of the rod tip portion 10c. It is preferable to set so that there is a position that coincides with, and it is particularly effective in a hydraulic cylinder type having a short retreat movement range P, but the retreat direction Y of the rod 10b and the arc locus X Even if the position that coincides with the tangential direction deviates from the receding movement range P slightly before and after the arc locus, it can be carried out as long as the required buffering capacity can be exhibited.

Further, in this case, immediately before the door body 5 stops, the roller support 6b on the hanger roller 6 side elastically contacts the stop member 15 provided on the suspension rail 7 side, and the door body 5 stops. When the body 5 is stopped, the braking function of the cushioning member 10 and the stopping member 15 is activated, so that a more excellent buffering action is performed at the time of stopping, and it is possible to suppress the generation of impact and noise.
Moreover, in this case, since the cushioning member 10 and the stop member 15 are provided on the suspension rail 7 side via the same bracket 13 in common, the mutual positioning arrangement of these members is simplified and the suspension rail 7 is arranged. It is easy to attach to and the workability is improved.

The present invention can be used for an arcuate door device for booths such as toilet booths and shower booths.
