Abstract

The utility model relates to a door support foot apparatus. The door support foot is composed of a support foot body, a fixing support seat, a pin axle, an elastic clip or a magnet. The support foot body is connected with the lower edge of the interior of a door plate by the fixing support seat and the pin axle, and the distance between the bottom surface of the support foot body and the center of the pin axle is appreciably bigger than the vertical distance from the center of the pin axle to the ground surface. When the utility model is used, the support foot body is put down and is supported on the ground surface, and the utility model can stop the door closing by the friction force between the support foot body and the ground surface.

Description

Door damper

The utility model relates to an a kind of door leg device that stops door to be closed, and is applicable to that removing of building is plug-type, installs and uses on the door of the various materials of automatic open-close type, specification, style.

The door of building (except that push-and-pull, the automatic open-close type) ventilation of often will opening the door for a long time, or for people's turnover, the carrying article are convenient and open door in following period of time.

Usually people's way be with can prevent the weight that door is shut keeping off, with rope yarn system haul, with hand push or haul, with health against etc. temporary measure, very inconvenient.Door is usually owing to wind is closed during ventilation, sends the strong collision sound with doorframe simultaneously, influences people's rests of working in quiet environment, causes the damage of door and doorframe, between doorframe and wall the generation crack and on every side the wall skin come off.

The purpose of this utility model is that a kind of door device of closing that stops will be provided, the degree that it can prevent effectively that door from closing and can control gate open.

The utility model is made up of leg body, fixed bearing, bearing pin, resilient clip or magnet.The leg body connects with the interior lower limb of door by fixed bearing, bearing pin.Leg body bottom surface is the anti-skidding garden of a dentation cambered surface, leg body bottom center is slightly larger than the vertical distance of bearing pin center to ground to the distance in bearing pin axle center, during use, the leg body puts down and props up on the ground, leg body center line becomes 15 °-45 ° with plumb line, stop door to be closed by means of the frictional force between leg bottom surface and ground (floor or the carpet).

Leg body of the present utility model is connected to two kinds of forms by the bearing pin on the fixed bearing and the couplet on the door: first kind of surface that is bearing pin perpendicular to door-plate, leg body rotate to the left or to the right around the bearing pin axial line and make it to enter and break away from user mode; Second kind is that bearing pin is parallel with the door-plate surface, and the leg body spins upside down around the bearing pin axial line and makes it to enter and break away from user mode.

In order to guarantee leg body smooth switch that does not influence door not in contact with the ground when not using, increase resilient clip or magnet as positioner, be fixed after making the leg body break away from the position on ground.First kind of connection form uses " S " type resilient clip to be contained on the side door of bearing pin, the leg body that (resilient clip can be made into one with fixed bearing) will be in user mode around bearing pin to the left or to the right half-twist can be blocked by resilient clip; Second kind of connection form use "

" the type resilient clip is contained on the top door of bearing pin, the leg body that (also can make one with fixed bearing) will be in user mode upwards overturns 145 °-165 °, can be blocked by resilient clip.Can also on the leg body, bury dress magnet, this moment, fixed bearing should be that steel plate (iron plate) is manufactured, magnet cartridge is in nearest middle part, non-working condition exchange premium door surface at the leg body, its surface that exposes outside is parallel to the plane that leg body middle part contacts with fixed bearing, contacts suction by magnet with the face of steel plate (iron plate) like this leg body is fixed.

The utility model is simple in structure, can be fixed on the mounted door with the gong nail, if reserved location can also overcome the defective of a leg device protrusion on the door surface when door is made.The frictional force size can move up and down and realize by the position that installs and fixes of adjusting the door leg device, thus install convenient especially.

The utility model cost of manufacture is low, and the leg body can adopt materials such as plastics, bakelite, rubber, timber, metal, and when being made by metal material, its bottom should use elasticity to make greater than the material of leg body.Bearing pin adopts standard component.

The external type of leg of the present utility model can be various, as the external form of toy, makes it have certain art value.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is a bearing pin and the embodiment schematic diagram of the vertical situation in door-plate surface.

Fig. 2 be the A of Fig. 1 to view, resilient clip and fixed bearing link in the illustrated embodiment.

Fig. 3 is a bearing pin and the embodiment schematic diagram of the parallel situation in door-plate surface.

Fig. 4 be the B of Fig. 3 to view, shown in implement in resilient clip be contained in the top of bearing pin.

1 is that fixed bearing 2 is bearing pin for leg body 3 among the figure

4 is that resilient clip 5 is magnet

Shown in Figure 2 as Fig. 1, bearing pin (3) is perpendicular to the surface of door-plate, resilient clip (4) is contained in the side of bearing pin, the leg body (2) that is in user mode (or to the right) half-twist left can be blocked the location by resilient clip (4), and resilient clip (4) can be made one with fixed bearing (1) for " S " type.Shown in Figure 4 as Fig. 3, the parallel surface with door-plate of bearing pin (3), resilient clip (4) is contained in the top of bearing pin (3), and the leg body (2) that is in user mode upwards overturns 145 °-165 ° and can be blocked the location by resilient clip (4), resilient clip (4) be "

" type can make one with fixed bearing (1).Or on leg body (2), adorn a magnet (5), and at this moment fixed bearing (1) is made for steel plate (iron plate), and leg body (2) upwards upset can make it break away from the position on ground leg body (2) location equally.
