Description

(54) SAFETY GATE (71) I, PETER WILLIAM JOHNSON 37, Deerhurst, Thundersley, Benfleet, Essex, formerly of 64 Brennan Road, W. Tilbury, Essex RM18 8BA, British Nationality do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to safety gates of a kind provided in doorways, passages, stairways and similar areas thus preventing babies and young children obtaining entrance into a dangerous area of a room, or using the stairs, by placing either at the top or bottom of stairways.

The object of this present invention is that whilst still allowing the gate frame to be adjusted to varying widths of stairways and doorways, without drilling holes to hold the frame in place, by using four independent rubber buffer pads which have a serated surface to give a good grip, thus giving a firm barrier to babies and young children, the gate gives a safe and easy access for adults and older children to areas that baby is unable to enter. The reason safe freedom is found is because the gate has pivot hinges on one post of the 'U' frame and a special sprung drop bolt which drops into a drilling on the corresponding 'U' frame post. The spring pressure of the bolt when lifted is such that young children and babies cannot push, pull up, even if shown how to use it. Adults and older children find the bolt pressure easy to negotiate, and the bolt springs back into position.

The four independent rubber buffers are on the end of four thread studs which are each adjusted to ensure a firm grip. Also one 'U' frame can be permanently adjusted at, for example, the top of a stairway, and one 'U' frame at the bottom of the stairway, using one common gate to both which can be lifted off the bottom 'U' frame and placed on the upstairs 'U' frame when baby is playing upstairs or at night when baby is sleeping in their first bed. Therefore 'U' frames can be placed and kept in doorways, stairways of varying widths, still using one common gate.

In addition where a baby is just crawling and is at the gate and an adult is unable to open the gate with baby obstructing it, the gate may then be lifted off the pivot hinges.

Care has been taken to cap the 'U' frame posts with rubber ferrules. Mastic ferrules are used to cap each thread stud which may protrude or may be cut down before capping. In addition fingers cannot be caught at any point of the gate, even when in use, with a view to complete safety.

In the accompanying drawings: Figure 1. Shows the complete gate set as seen from the front elevation and manufactured of extruded tubular aluminium. The pivot hinges part B may set for the gate to open from right to left or left to right.

Figure 2. Where the gate is lifted off as previously described the 'U' frame part A is held in position by the rubber buffers, parts B1 and adjusted by the thread studs, parts C, all capped for safety with plastic ferrules parts B3. The thread studs part C are held in a sturdy position by locking nuts parts C1. The top of the 'U' frame part (A) posts are capped with rubber ferrules B2 for safety.

The pivot hinges (B) are set in, precisely in the same place on the 'U' frame (A) thus ensuring all gates Al are placed on any number of 'U' frames (A).

Figure 3. The 'U' frame (A) is in its position when not held in a doorway or stairway, nor held in position by the drop bolt part (E) on gate (Al) which would drop into part (D) on the 'U' frame (A). As fully illustrated in Fig. 5. As the material is of extruded tubular aluminium it gives a good outward pressure from the position of a U shape, pushing outward to the walls of a stairway or door frame. In Figure 4 the actual gate (Al) is shown when lifted from the 'U' frame (A) and comprises of vertical cylindrical bars, being parts Al, A2, A3 and A4, also identifying the bolt (E) being all the parts shown.

The bar A2 is the holding bar and is riveted at both ends A4 thus keeping the gate frame (Al) in its shape of a U also holding all A3 bars in place.

In figure 5 the full detail of the important item of the sprung drop bolt specially designed for the gate, for safety, and with modification the spring (G) may be enclosed by a casing. The bolt (E) when lifted is immediately under pressure from the spring G, which is simply negotiated by adults and older children. Babies between 9 months and two years old cannot push, pull the bolt due to the pressure. Parts El self tapping screws keep part E bolt in the drop position as required, set in part D drilling set on the CU' frame (A). The complete sprung bolt unit, the holt E, self tapping screws (El) and Ibe spring (G) are held together by the housing part (F), which is riveted to Al the gate.

WHAT I CLAIM IS: 1. A safety gate with an adjustable frame which fits into doorways or stairways of varying widths with the frame being kept in the shape of a U by the outward pressure to the walls or door frames, the limbs ot the U each carrying two independent buffer pads to engage the walls or door frames, the pads being adjusted by independent threads, then held by four locking nuts.

2. A safety gate as in claim 1 with a gate portion removable from the 'U' frame.

3. A safety gate as in claims 1 and 2 with the removable gate having vertical cylindrical bars spaced apart froml each other.

4. A safety gate according to aforementioned claims with a sprung bolt which provides strong pressure to ensure the bolt springs back into place and cannot be easily lifted up.

5. A safety gate as in aformentioned claims with pivot hinges on the 'U' frame to give good free movement when the gate is in use.

6. A safety gate completely constructed as shown in Fig. 1 of the accompanying figures in the drawings.
