FR2956872A1 - Device for controlling leg utilized to open, close and lock door of premises of medical place e.g. hospital, has pedal levers respectively arranged in protection and guiding pads that are provided on two sides of door - Google Patents

Abstract

The device has pedal levers (A1, A2) respectively arranged in protection and guiding pads (G), where the protection and guiding pads are provided on two sides of a door. A lever or latch or cam (C1) is located at an initial location of a handle. Mechanical transmissions (B1) integrate a pedal to ends (D1, D2).

Description

-1-

The present invention relates to a foot control device for opening, closing and locking the doors of rooms equipped with a bolt lock launching actuated actuated, in the prior state of the art, by a button or a manual latch handle and / or equipped with a deadbolt latch initially actuated by a manual button.

The invention is a purely mechanical device which has two essential purposes, one hygienic and sanitary, the other practical and which constitute claims 1 and 2 as described in the paragraph of the claims of this invention.

The two purposes of the device according to the invention are: In cases where hygiene or public health so require, the first object is to replace the latch handles and manual buttons previously existing locks allowing them to be completely removed and thus eliminating the risks of cross-contamination inherent to stains of all kinds, such as germs, microbes, viruses that can be deposited by the hands on these door handles and manual lock buttons. - The device of the invention has the second purpose to allow the opening, closing and locking doors to people who do not use their hands or people with both hands cluttered.

The device is applicable to latch bolt door locks, or deadbolts, and their dead bolt locks; especially at the doors of rooms and other premises of places with medical purposes such as hospitals, clinics, health centers, at the doors of toilets, cafes, bars, restaurants and generally at the doors of places frequented or not by the public and for which one or both of the first two claims are desirable or necessary or for any other reason.

As described in the drawings No. 1 and No. 2 attached, the device according to the invention can be achieved by different means only mechanical and in the absence of any external source of energy, whether electric, pneumatic or hydraulic .

The device according to the invention is actuated by means of the foot and consists of: 1 °) Two or three pedal levers (Al, A2, A3 in the drawings 1 and 2) respectively contained in protective shoes and guide (G in drawings 1 and 2) located on either side of the door, fixed thereto at its lower part, recessed in its thickness, and receiving pedals supports or taking place. The support or lift exerted by the foot in a vertical axis on one of these pedals pulls or pushes a transmission (B1, B2 on drawings 1 and 2) described in 3 °) below.

2 °) A lever, or latch or cam (C1, C2 on the drawings 1 and 2), located at the original location of the handle, latch or button of origin and, replacing it, replaces the function and thus suppresses the use and the presence. This latch or cam, under the traction or thrust of the mechanical transmission (B1, B2), describes an angular displacement of the value of that described by the handle, latch or button manuals of origin and operates in its axis of rotation at the level of the nut, the original conductive axis of the bolt of the lock or latch (F in drawings 1 and 2). 2956872 -2-

3 °) A mechanical transmission (B1, B2 in drawings 1 and 2) of the vertical movement of the pedal to the latch or cam. This transmission, integral with the pedal at one end (D1, D2 in the drawings 1 and 2) and the portion opposite the axis of rotation of the latch or cam at the other end (E1, E2 in the drawings 1 and 2), being constituted either by a rod or rod of metal (B2 in the drawing No. 2) or any other material and any section, profile or shape, or by a bare cable or sliding sheath (B l in drawing No. 1), either by a wire or a metal chain or any other material, either by a rope, a strap or a strap, or even by a set of pinions or gears, or by a joint shaft 10 homokinetic or a connecting rod.

The movement of the door opening or closing is obtained by moving the leg, the foot being held on the pedal gripping surface, instead of the hand and the arm used for the handles and manual buttons in the previous state of the technique.

4 °) The entire device is covered by a cowling or safety guard and cleanliness prohibiting, except disassemble, access to the transmission members and the upper organs of the device.

In cases where hygiene, public health and / or convenience so require, the only mechanical foot-operated device integral with the door, operates completely autonomously, independently of any external accessory to the door alone and does not use any source of energy, be it electric, pneumatic or hydraulic. This device fits standard doors without requiring modification other than a cut at the bottom of them according to the outer shape of the hooves containing the pedals. A 1/1 scale template is provided for this purpose. It also has the advantage of being operational by achieving its objectives regardless of the direction of opening or closing of the door. For these reasons, the cost of manufacturing, implementation and maintenance of this device are particularly reduced.

The invention is therefore likely to be exploited industrially by applying in particular to the doors of rooms and other premises of places with medical vocations such as hospitals, clinics, health centers, doors of toilets cafes, bars , restaurants and generally at the doors of public and non-public places for which one or both of the first and second claims are desirable or necessary or for any other reason.

Claims (10)

CLAIMS 1) Device eliminating the risk of cross-contamination inherent in the stains of all kinds, germs, viruses or microbes that are deposited by the hands on the handles, latches or door knobs. 2) Device for opening, closing and locking doors 5 to people who do not use their hands or people with both hands cluttered. 3) A device that replaces the handles or latches of bolt door locks and deadbolt lock buttons so as to replace the function and thus to eliminate their use and presence. 10 4) Only mechanical foot control device, integral with the door, operating completely autonomously, independently of any accessory outside the door and not using any source of energy, whether electric, pneumatic or hydraulic . 5) Two or three levers or pedals (A1, A2, A3 in the drawings 1 and 2) respectively contained in protective and guiding shoes (G in the drawings 1 and 2) located on either side of the door, attached to it in its lower part and receiving pedals supports or taking place. 6) A lever or cam or latch located at the original location of the handle, latch or original button of the lock or lock and replacing it; said latch or cam actuating in its axis of rotation at the nut, the original conductive axis (F in the drawings 1 and 2) of the lock or latch. 7) A mechanical transmission of the movement of the pedal to the latch or cam, said transmission, (B1 and B2 in the drawings 1 and 2) integral with the pedal (A1, A2, A3 in the drawings 1 and 2) at one end and the lever latch or cam (C 1 in the drawing No. 1 and C2 in the drawing No. 2) at the other end, being constituted either by a rod or metal rod (B2 in the drawing No. 2) or any other material of any section, profile or shape; either by bare or sheathed cable; (B l in drawing No. 1); either by a wire or a metal chain or any other material; either by a rope, a thong or a strap; either by a set of gears or gears; either by a homokinetic joint shaft or a connecting rod. 8) The entire device is covered by a cowling or safety guard and cleanliness prohibiting, except disassemble, access to the transmission members and the upper organs of the device. 9) The device according to the invention adapts to doors provided with locks whose launch bolt is actuated by means of a square conductive axis or an axis of any section or shape, including fluted, some in the dimensions. 2956872 -4- 10) The device according to the invention replaces the dead bolt lock button integrated or not to a lock and operable via a square conductive axis or an axis of any section or shape, including fluted, some in the dimensions.
