This invention consists of a suspension system that is a significant improvement over known models, both in simplicity and strength, characterised by the fact that whatever the pressure on the suspension, the wheel remains in correct vertical position at all times. The characteristic feature of this suspension is that it has two longitudinal elements between the frame (1) and the wheel (3) support (2), substantially parallel and their ends are articulated onto the frame and the support, with a damper (10) located between the articulations of the opposite ends of the longitudinal elements. The damper device (10) is a telescopic element with a spring (13) inside it and the longitudinal elements are composed of plates (4,5).

This invention consists of a lockable handlebar articulation for baby pushchairs presenting a simplified design and easily accessible locking action. For this purpose, the articulation is characterised by having a block on the lower end of the handlebar sides (1) that has a cylindrical hole (3) going through it, through which an articulation turns on a fixed shaft (4) fitted to a crossmember (8) of the pushchair frame, these blocks and shafts have means to lock the handlebar in at least two positions of rotation. The locking action is achieved by a rod (10) in the mentioned block (2), which fits selectively into one of the radial cavities (11,12) in the periphery of the shaft. This rod (10) is pushed by a spring (13) that ensures it fits into the chosen recess (11,12) of the shaft (4) and is joined to a cable (14) used for unlocking by pulling.

The invention refers to improvements to steering column supports, in which this support incorporates several functions, such as: securing the steering column to the vehicle; pivoting the column shaft to enable height adjustment of the vehicle steering wheel; support for the anchoring system of said height (and depth if required) adjustment system for the vehicle steering wheel position; an energy absorption system if the column collapses, necessary in case of collision; support for any other system around the column, such as electric cables, springs, etc.

The undesired manipulation of the ball valves that have a visible lever for the action may cause problems and also serious accidents. These drawbacks or problems, and others that are derived from them, can be solved with the valve described in this invention, which has a cap (5) covering the part of the shaft (3) projecting from the tubular body (1) and which has inside means to engage to the shaft (3) and turn it and also means to secure it on the shaft (3) that can be manipulated from outside using a key (M) that accesses it through an opening (15) at the top of the cap (5).

The purpose of this invention is to provide these types of pushchairs with a protective railing (2,3,4) that stops children leaving the seat and at the same time protects from accidental frontal impact, this railing (2,3,4) can be fitted to any pushchair of the aforementioned type without any modifications, for which the railing has an articulated frame (1) that fits to the articulations of the handlebar arm (8) with the front legs (9), the frame (1) presenting, at its ends, two stops (10,11) that rest on the back of the aforementioned articulations, in addition, the presence of this railing does not hinder the folding of the pushchair, as it folds automatically when folding the pushchair itself, the frame of the railing (2,3,4) is articulated in the linkage of the handlebar arms (8) with the front legs, by means of end side members that are finished with the aforementioned stops.

The invention relates to a positioning cylinder (1) for a surgical drill, which positioning cylinder is screwed into a drilling jig by means of an external thread (4), especially for drilling in a jawbone for a dental implant. The positioning cylinder comprises a cylinder base (2) having an axial internal bore (3) and an external thread (4) for screwing it into the drilling jig. The positioning cylinder (1) is designed as a one-piece or integral part and the internal bore (3) is used to guide the drill. The invention further relates to a system consisting of said positioning cylinders (1) and surgical drills.

The invention proposes a socket base for low voltage electrical circuits installed projecting from the wall or partition. The aim of the invention means that it is manufactured in one single piece so that the body's base and the earth housing mechanism, which are usually lateral metal contacts located in a cylinder connected to the base, form a single solid body with optimum external appearance and finish.
