Abstract
Description
- The present invention generally relates to a door closing sequence controller, and more particularly to a door closing sequence controller that utilizes a locking mechanism to achieve door sequence control.
- In doors with at least two door panels there is a leading panel and a trailing panel. Because of different structures and functions the leading panel and trailing panel must close in sequence, i.e. the leading panel is closes before the trailing panel. It has to be made sure that the leading panel and the trailing panel can be closed in sequence by a user.
Fig. 1 shows a conventional door selector for a double door which is known fromDE 10111732 Al to assist a user to correctly close the leading door and the trailing door, wherein a sliding rod R connected with the trailing door is penetrated through a circular plate O. The mobility and door closing sequence of the sliding rod R can be controlled by adjusting swing angles of the circular plate O. When the leading panel and the trailing panel are both open, swing angles of the circular plate O are greater than zero degree (cf. dashed line inFig. 1 ). The sliding rod R may be blocked by the circular plate O to enable the sliding rod R to be unable to move, so that the trailing panel can be prevented from close in advance. Comparatively, when the leading panel closes in advance, swing angle of the circular plate O can be adjusted to zero degree solid line to release the sliding rod R. Due to the sliding rod R is capable of moving without limitation, the trailing panel can be closed smoothly. However, conventional circular plate O possesses thinner structure and small contact area contacted with the sliding rod R which may cause stress concentration to deform the circular plate O after long-term usage, and the function of door closing sequence may be failed. - The object of the present invention is to increase the lifetime of a door closing sequence controller.
- This technical problem is solved by a door closing sequence controller according to
claim 1. Advantageous embodiments are indicated in further claims. - The door closing sequence controller according to the present invention can be used to control the closing sequence between a leading panel having a first door closer and a trailing panel having a second door closer. It comprises a first actuator mechanism connected with the first door closer, a second actuator mechanism connected with the second door closer, a fixing base disposed between the first actuator mechanism and the second actuator mechanism, a movable base movably disposed at the fixing base, a locking mechanism movably disposed in the movable base, and a blocking pin selectively disposed into an accommodating space of the movable base. The locking mechanism remains clamping the second actuator mechanism until the first actuator mechanism interacts with the locking mechanism, such that the locking mechanism can release the second actuator mechanism from clamping. The blocking pin may contact against the locking mechanism to prevent the locking mechanism from moving relative to the movable base.
- This invention may utilize the locking mechanism to tightly clamp the second actuator mechanism thereby preventing the second actuator mechanism from moving. When a user intends to close the trailing panel in advance, for the reason that the second actuator mechanism is incapable of moving, the trailing panel can be kept from closing in advance. Instead, when a user closes the leading panel in advance, the locking mechanism can be pushed by the first actuator mechanism to enable the second actuator mechanism to disengage with the locking mechanism. Meanwhile, the second actuator mechanism can be restored into a movable state and the trailing panel can be closed fluently. Besides, the contact area between the locking mechanism and the second actuator mechanism is substantially increased, therefore, the suppression force applied to the second actuator mechanism can be raised and the lifetime of the door closing sequence controller can be effectively extended.

First,Figs. 2 ,5 and5A indicate components diagram of the doorclosing sequence controller 10 when the leading panel F and the trailing panel M are both open, wherein each of the lockingelements 151 can be pushed by thefirst spring 18 and thereafter located between each of therollers 17, each of the lockingelements 151 can be pressed to the other by limitation of each of therollers 17 as a clamping state, then therod 122 is capable of being clamped by thearc walls 152a of thearc slots 152 to enable therod 122 to be unable to move thereby preventing the trailing panel M from being closed in advance. - Next, referring to
Figs. 2 ,6 and6A , when the leading panel F is closed, the first slidingblock 111 of thefirst actuator mechanism 11 is driven by the first door closer C1, the first slidingblock 111 of thefirst actuator mechanism 11 contacts against the pushingblock 113 to move toward the fixingbase 13. Sequentially, the pushingblock 113 may actuate thesecond part 112e of thetube 112 to push the adjustingnut 19 to move. Owing to the adjustingnut 19 being tightly screwed onto thefirst part 112d of thetube 112, so that thefirst part 112d moves as well, and thesecond end 112b may push thelocking elements 151. Therefore, the lockingelements 151 may slightly depart from therollers 17 and compress thefirst spring 18. When the lockingelements 151 are slightly departed from each of therollers 17, the clamping state of the lockingelements 151 is disengaged. Meanwhile, thearc wall 152a of each of thearc slots 152 may loosen therod 122, i.e. therod 122 will not be clamped by each of the lockingelements 151 and will be free to move to enable the trailing panel M to close smoothly. In this embodiment, when each of the lockingelements 151 is pushed by thetube 112, the third spring S2 may be compressed by the retaining ring U. In addition, when the leading panel F and the trailing panel M are reopened, the retaining ring U may be pushed by the third spring S2 so that thetube 112 can be restored. - With reference to
Figs. 2 ,7 and7A , in order to prevent a destruction from forcibly closing the trailing panel M in advance, when the closing force of the trailing panel M is greater than the tension force of the second spring S1, themovable base 14 and therollers 17 may move toward the supportingplate 133 of the fixingbase 13, the second spring S1 can be pushed by themovable base 14, and each of the lockingelements 151 is movable toward thetube 112. The lockingelements 151 are blocked to stop moving when each of the lockingelements 151 is in contact against thetube 112, themovable base 14 and therollers 17 may continue to move toward the supportingplate 133, and each of the lockingelements 151 is loose gradually from each of therollers 17 and disengaged from the clamping state. Meanwhile, therod 122 is loose from thearc wall 152a of each of thearc slots 152 so that the trailing panel M can be forcibly closed thereby preventing the doorclosing sequence controller 10 from destruction. - To disengage the closing sequence can be referred to
Fig. 8 . First, maintaining the trailing panel M and the leading panel F into an open state. Then, disengaging a screwed state of the adjustingnut 19 originally screwed by thescrew 19a and enabling the adjustingnut 19 to move toward the direction of the fixingbase 13 till thesecond part 112e of thetube 112 pushed by the pushingblock 113 incapable of contacting the adjustingnut 19. Referring toFig. 9 , after that, actuating thefirst part 112d of thetube 112 to move toward the fixingbase 13 thereby pushing the lockingelements 151. Therefore, the lockingelements 151 may slightly depart from therollers 17 and the clamping state of the lockingelements 151 is disengaged, at the same time, the blockingpin 16 is disposed into the combination holes 131c and protruded to thetop surface 131a to limit the lockingelements 151 from moving. Then, with reference toFig. 10 , loosing thefirst part 112d of thetube 112 and inserting the blockingpin 16 more deeply, on the other hand, the third spring S2 provides elasticity to actuate thefirst part 112d to move toward the first slidingblock 111. Owing to the lockingelements 151 being limited by the blockingpin 16, the lockingelements 151 can not move and remain in the disengaged state even if the elasticity of thefirst spring 18 is provided. By utilizing mentioned operation, when the leading panel F and the trailing panel M are both open, one end of each of the lockingelements 151 is capable of being pushed by thefirst spring 18, however, another end of each of the lockingelements 151 is blocked by the blockingpin 16 to stop moving toward the direction of the supportingplate 133 of the fixingbase 13. Therefore, therod 122 is not able to be clamped by the lockingelements 151. Besides, therod 122 can be moved back and forth without limitation so that the function of door closing sequence can be effectively disengaged. As a result, the trailing panel M may close itself and is independent of the movement of the leading panel F. With reference toFig. 11 , for the reason that the screwing position of the adjustingnut 19 has changed, thesecond part 112e can not contact and push the adjustingnut 19 even if the leading panel F closes in advance to enable the first slidingblock 111 to contact against the pushingblock 113. Therefore, thefirst part 112d of thetube 112 will not be actuated and may not contact the lockingelements 151 while the leading panel F closes in advance. Eventually, the clamping state of the lockingelements 151 can remain disengage. - This invention utilizes the
rollers 17 to limit the lockingelements 151 and enable therod 122 to be clamped by the lockingelements 151 thereby preventing therod 122 from moving. When a user tends to close the trailing panel M in advance, for the reason that therod 122 is incapable of moving, the trailing panel M is not able to close in advance. Comparatively, when a user closes the leading panel F in advance, each of the lockingelements 151 may be pushed by thetube 112 to enable each of the lockingelements 151 to depart from each of therollers 17 so that the clamping state can be disengaged. Meanwhile, therod 122 is restored into a movable state, and the trailing panel M can be closed smoothly. In this invention, the contact area between each of the lockingelements 151 and therod 122 increases substantially, therefore, the suppression force to therod 122 can be raised and the lifetime of the doorclosing sequence controller 10 can be effectively extended. - While this invention has been particularly illustrated and described in detail with respect to the preferred embodiments thereof, it is to be understood that the invention is not limited to the specific embodiments shown and described and that various modifications and changes may be made without departing from the scope of the claims.
