Abstract
The utility model relates to a stopping device for a door leaf, which is designed according to the principle that a supporting rod is rubbed and self-locked to the ground. The utility model is composed of a fixed body of the supporting rod, a pin shaft, the supporting rod and a friction pad and is installed on the lower corner of the door leaf; when a door is opened, the supporting rod is put down and can be appressed with the ground all the time along with the surface relief of the ground, and friction and self-locking performance towards the ground is generated; the door is stopped in a single direction when the door is opened at any position; when the door is closed, the utility model can be attracted with a magnetic door which is installed on a doorframe to generate stopping force for preventing the door leaf from opening. The utility model is especially suitable for articulated house doors and spring doors.
Description
The utility model relate to a kind of can be with door leaf, particularly the device of the unidirectional stop of radial type door leaf belongs to the architectural hardware series products.
The phenomenon that nature is closed because of factor affecting such as cross-ventilations, can take place in door opening state in the radial type door leaf.Existing can prevent device that door leaf cuts out naturally as: " foot-operated door check " is a kind of door leaf inferior horn place that is installed in, and utilizes and the frictional force on the ground device with the door leaf location.When on the optional position that door is opened, needing door leaf located, with the stop treadle on the foot-operated door check down, treadle promptly is locked on the relevant position by the latching force that a spring produces, and the rubber cushion of treadle lower end contacts with ground, produces certain frictional force door is located.Because treadle is perpendicular to ground motion, the size of frictional force depends on that spring is to the latching force of treadle and the friction factor on rubber cushion and ground.This device in use exposes such problem: the frictional force on treadle and ground can not change with the size of external force effect, and when door closing force during greater than maximum static friction force, door will move, so it can not be used for door closing force apart from bigger swinging door.Have, the flooring is not a level, has certain inclination and fluctuating in architectural process again.The treadle that vertically depresses is behind a certain point location, and the fluctuating that can not follow ground voluntarily is close proximity to ground all the time, has displacement just might produce the gap with ground slightly, loses the stop ability.
The purpose of this utility model is that a kind of strut friction self-locking principle and novel door leaf stop device of designing over the ground of utilizing will be provided, it can adapt to surface relief and change, all the time close proximity to ground, the size of frictional force can increase with the increase of external force, stops door leaf monodisplacement under external force effectively.
The purpose of this utility model is achieved in that on door and is screwed at door leaf inferior horn place by adorning a kind of Jackstay type door leaf stop device that the door leaf stop device is made up of strut fixed body, bearing pin, strut and friction pad; Strut one end has the hinge hole, is hinged by bearing pin and strut fixed body, and the other end has an inclined-plane to link to each other with friction pad; The strut fixed body is screwed on door, and when it highly made strut have an end of friction pad to contact to earth, the angle on strut and ground can form friction self-locking over the ground less than the friction self-locking angle on friction pad and ground, stops door leaf to the side shifting that strut is arranged; When strut when bearing pin upwards rotates, can be remained on vertical position by strut fixed body biside plate, but the door free switch.
Owing to adopt strut as supporting the stop original paper, when putting down strut, the strut upper end is hinged, and contacts to earth in the lower end, so in the overall process that door opens and closes, strut contacts by remaining with ground from Beijing South Maxpower Technology Co. Ltd; Again since the angle on strut and ground less than the friction self-locking angle on friction pad and ground, at an arbitrary position at closing time, door closing force all can form the friction self-locking on strut and ground, produces enough stopping powers, reliably door holder is moved.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1, Fig. 2 are the front view and the lateral view of Jackstay type door leaf stop device.
Front view and attached view when Fig. 3, Fig. 4 are Jackstay type door leaf stop device and magnetic door-inhale cooperating.
Below in conjunction with description of drawings ins and outs of the present utility model and working condition.
Jackstay type door leaf stop device (1) is installed in door leaf (10) inferior horn place, and it is made up of strut fixed body (6), bearing pin (7), strut (8) and friction pad (9).The bevelled end of strut (8) is connected so that increase frictional force over the ground with rubber cushion (9), the other end is hinged by bearing pin (7) and strut fixed body (6), strut fixed body (6) is fixed on the door leaf inferior horn place of door leaf (10) by screw (5), when it highly makes strut that one end in contact ground of friction pad (9) is arranged, the angle α on strut and ground is less than the friction self-locking angle on rubber cushion and ground, door closing force F makes strut form friction self-locking over the ground to make the door can not be to the side shifting that strut is arranged, and door is by unidirectional stop.When stirring strut (8) when bearing pin upwards turns on the strut fixed body (6), can be remained on vertical position by biside plate (2), but the door freely openable.
Strut fixed body (6) is made of base plate (3) and side plate (2), screw hole (4) is arranged on the base plate, biside plate from the base plate two ends to a lateral bending song, vertical with base plate, the hinge hole parallel with base plate arranged at the side plate bottom, is hinged by bearing pin (7) and strut (8), and biside plate top and strut are interference fit on width, make strut when vertical position, can be remained on vertical position, can not rotate voluntarily by biside plate.
For make Jackstay type door leaf stop device at the state of closing the door according to the miscellaneous function that has the resistance door leaf to open, the base plate (3) that strut is decided body can be made to both sides and extend two planes (11); At the state of closing the door, this plane can with magnetic door-inhale (12) adhesive that is installed on doorframe (13) correspondence position, produce stopping power, stop door leaf to be opened.The strut fixed body is made the axisymmetric shape member usually, can both be used with the magnetic door-inhale so that be installed on left hand model door or the right hand model door.
This device is particularly suitable for using on hinge door in various buildings and the swinging door, for only preventing the occasion that door leaf cuts out naturally in door opening state, can use Jackstay type door leaf stop device separately, for not only need but also preventing the occasion that door leaf opens and closes naturally, Jackstay type door leaf stop device and magnetic door-inhale can be used in door opening state at the state of closing the door.
