NL8100211A - Fixture on motor car for e.g. bicycle carrier - fits over towing bar ball head, is secured to plate clamped under horizontal part of head - Google Patents

Abstract

The fixture is intended for securing a carrier to the towing bar ball head of a motor car, e.g. for carrying bulky items such as a bicycle. It comprises a tubular element (1) with internal collar (2) at its upper end to seat on top of the ball head, a support plate (5) fixed below the horizontal portion of the L-shaped ball head by a screw clamp (10), and screws (6) to secure the element (1) to the plate (5). The element is provided with a cut-out (4) at its underside to fit over the said horizontal portion. This fixture can be used as support for a carrier of suitable shape to hold the bulky luggage.

Ball carrier for transporting luggage, bicycles, etc., characterized in that the load-bearing part can be mounted on the ball of the tow bar

Transporting more bulky luggage, such as e.g. bicycles, etc., by means of passenger cars gives various problems. The solution is often sought in mounting a roof rack on the roof of the car. More bulky luggage not only causes more driving resistance and wind noise as well as paint damage, but also higher fuel consumption. In addition, the mounting of a roof rack on the eaves of the vehicle cannot be labeled as very solid. Even without load, any-10 equal luggage rack gives rise to higher fuel consumption? figures have already been published on this.

Due to the often very cumbersome way of mounting and dismantling luggage racks, the rack often remains on the car, even for longer periods, while it is not in use.

15 When disassembling, the large and clumsy rack will have to be stored somewhere; this is not possible in the luggage compartment of the car.

The invention aims to overcome these drawbacks.

The construction is based on the fact that, in accordance with national regulations, the towbar can be counted as the most solid attachment point of the passenger car: it can absorb both tension and pressure.

The confirmation is explained using the following sketches. Drawing 1 shows two cross sections of the mounting on the ball. Drawing 2 shows some variations on the application.

Drawing 3 shows a rear view and top view of a retractable construction.

The construction consists of a tubular (preferably circular in cross-section, but also other cross-sectional shapes are possible) part 1 (drawing 1), the upper part of which has a fitting edge 2 on the inside, which is adapted to the normalized ball diameter of the towing hook. Part 1 is provided with an opening 4, which easily closes over the horizontal part of the tow bar. Some studs are attached to part 1, which fall into the holes provided in clamping plate 5 and are tightened by two knurled nuts 6 on clamping plate 5, so that sleeve 1 is tightened on fitting edge 2. Clamping plate 5 is attached to the horizontal part of the tow bar 35 by means of a clamping bracket and two bolts at 10. In addition, part of plate 5 can be placed over e.g. a distance B must be converted according to the roundness of the tow bar 8100211 * * '•' -2- 1. - .-. .-to obtain a larger clamping surface.

The lateral movements according to pylons 8 and 9 are hindered by the fact that the bottom of sleeve 1 cannot rotate at points A with respect to plate 5. The studs will also hinder this.

The sides of recess 4 in sleeve 1, which falls around the horizontal part of the tow bar, also hinder the turning of sleeve 1 in the horizontal plane; the studs also prevent rotation in this plane. The bearing point 7 will then also come into its own even better, because plate 5 is partly bent over distance B 10 (drawing 1).

Almost any supporting construction can be mounted on the tubular part 1. The construction emphasizes the requirements that fast assembly and disassembly must be possible and that the whole can be carried in the trunk of the vehicle.

15, therefore, a folding and extendable version is shown.
