Abstract

The invention relates to a door brake comprising a brake element (11) arranged on the bottom of a door (1), which is distinguished by its adjustability and functional reliability and can be integrated completely in the door (1), wherein the brake element (11) is adjustably guided in the door (1) for the purpose of implementing such a door brake for doors (1) and can be moved forward by means of an actuator controlled by the door movement from a retracted basic position when the door is closed to a braking position in which the brake element protrudes beyond the lower edge of the door when the door is open.

Description

The door brake

Affiliated field

The present invention relates to a kind of and use brake, this brake has a braking member that is arranged on a bottom.

Background technology

In order to make a location known by WO 92/03630, on the door-plate of student's seamed edge, be furnished with the setting element of assembling, door can be positioned at open angle arbitrarily by this element by means of wedge embedding with the floor.The wedge embedding of door or get loose by manually eccentric wheel being fallen or lifted and realize, so these setting elements are not suitable for limiting the open angle of door and can not be integrated into the door-plate the inside.

In addition, in order to prevent a bump wall, equipment or other obstruction, known will being fixed on floor or the wall by braking or the stop element that rubber or plastics are made.These brakes are fixing assemblings and obviously visible, and the brake body of their projection brings difficulty for floor cleaning or similar work.

Summary of the invention

Therefore the objective of the invention is, the brake of above-mentioned form is provided, this brake is with its adjustable and functional reliability and unusual, and can be fully integrated in the door the inside.

Purpose of the present invention realizes therefrom, promptly the braking member adjustable ground be arranged on Men Nei and the home position of the withdrawal braking member can be closed by door by an executing agency that controls by the action of door the time when moving forward to door and opening braking member protrude in the application position of student's seamed edge.

Acting in conjunction by braking member and executing agency, braking member is forwarded to application position or is forwarded to home position by application position by home position according to the width of opening of door, makes door or braking at given open position or for making an action brake off thus.Because braking member and executing agency are arranged on the following seamed edge place of door, thereby is sightless to a great extent at this, and also need not fixing assembling backstop or similar object on floor or wall.

Advantageously, executing agency is made up of a slide bar and a pull bar, described slide bar supports in the mode that can regulate slip along student's seamed edge, be used for the vertically immovably rotation of the braking member of guiding adjusting, described pull bar is used for the door pivot spacer is liftoff slide bar being hinged on door jamb or floor.When door moves and the pull bar of door pivot off-centre support slide bar relatively moved for door, can regulate braking member by slide bar in reliable in function ground thus.

If pull bar is made up of hinge connection, threaded rod and the riffled tube that is used for length adjustment, then can access simple adjustable structure, because by means of this pull bar, slide bar can move and adjust to thus a definite door application position with respect to braking member.

If pull bar is made up of hinge connection, threaded rod and helical spring, helical spring has end section that a circle twines by a circle and space apart from the end section of twining, and be spun on the threaded rod by the end section that a circle twines with the one circle, and be hinged on the slide bar with its other end sections, then pull bar not only can carry out length adjustment by threaded rod and helical spring, and helical spring can additionally compensate rigging error and the kinematic error between slide bar and the pull bar and be buffered in the motion impact that produces when braking.

If having one at the braking member place, slide bar has the cannelure of widening, and braking member is rabbeted in the groove the inside by guide protrusions, just can guarantee that the divertical motion that braking member fast and does not frictionally cause by gravity and elastic force with the floor works and can directly turn back the home position direction by its application position owing to widen the slideway that provides when door is closed.

The embodiment explanation

Door 1 usefulness brake comprises an executing agency that is furnished with the braking member 11 and a braking member 11 of braking surface 12.Executing agency is made up of the pull bar of being made up of riffled tube 4, threaded rod 5 and hinge member 6 that slide bar 7 and of a guiding on slide bar bearing 8 can vertically regulate.Brake setting-in or screw thread are fixed on milling mouthful or groove 2 the insides on the door-plate bottom surface 1.Slide bar 7 has a cannelure 9 and is positioned at a slide bar bearing 8 on the common backplane by two and leads in the mode that can regulate slip along the sliding part or the pin 10 of student's seamed edge by slide bar bearing 8.Slide bar 7 is supporting braking member 11 between bearing 8, wherein the cannelure 9 of slide bar 7 is furnished with at the braking member place and widens 14, and braking member 11 advances cannelure 9 with guide protrusions 13 interlockings.The other end is connected with the pipe 4 that bearing 3 is guided one end of hinge member 6 with liftoff be hinged on the door jamb 15 of door 1 rotating shaft spacer.Slide bar 7 can vertically be connected by threaded rod 5 with pipe 4 with regulating.

Comprise that the brake 11 of one or more braking members 11 (seeing Fig. 6-8 and Fig. 9 and 10) is positioned at the home position (seeing Figure 12) of its withdrawal when door is closed.When door was opened, therefore door-plate also spurred slide bar 7 towards the direction of door jamb 15 along with the increase of open angle relatively away from the pin joint of hinge member 6 (seeing Figure 11).From the door open angle that can adjust by threaded rod, braking member by slide bar cannelure 9 widen 14 discharge, thereby and along with door is braked in the rotation upset downwards around the slide bar longitudinal axis.Deadweight by braking member 11 or spring prestressing force are realized the upset of the application position of the home position of braking member 11 when it is closed when it is opened, and braking member 11 is by forming slideway and turn back the home position direction by widening 14 when door is closed, and this will prevent friction or the slip of braking member on the floor do not expected.

Use a helical spring 17 to replace pipe 4 on pull bar according to one the of the present invention embodiment (seeing Figure 13) that modification arranged slightly, the end section that helical spring 17 twines by a circle with the one circle is spun on the threaded rod 5 and has the space apart from the end section interlocking of the turn groove the inside at slide bar 7 with it.This helical spring 17 equally can the axial adjustment pull bar, and it is compensating motion error and the shock loading that produces when being buffered in braking additionally.
