FR2760370A1 - Cushion to protect neck during gymnastic exercises - Google Patents

Abstract

The cushion is rectangular and is made of high density compressed foam material and is covered with a removable cover (5). Two straps (1) are fixed to the sides of the cover and they can be removable and fixed to the cover by press studs or strips of hooked pile fasteners. The straps form loops (6) on either side of the cushion and these are pulled to deform the cushion round the neck. The sides of the cushion are thicker (4) and are placed on either side of the head to hold the neck.

Description

 The present invention relates to a cushion which allows the protection of the joints during gymnastic exercises, traditionally performed on the ground.

None of the existing products combine the qualities necessary to increase the efficiency of muscle work and comfort. They are generally pillow or bolster type and are used only as a headrest and not as physical exercise equipment.

 The particular ergonomic shape of the cushion, its components and the supply of straps make it possible to overcome the various drawbacks inherent in the practice of certain gymnastic movements.

For the work of the abdominals it indeed has two removable straps with handles, which, subjected to a traction by the author of the exercise cause, the curving of the cushion and the placement of two gutters in blocking of the head jointly with the cervical vertebrae and the first two dorsal vertebrae, thus avoiding the whip effect of the neck due to fatigue; the spine thus supported, energy is supplied in the abdominal strap exclusively
The use for the manufacture of this cushion of a high density agglomerated foam with a thickness of 2 cm on average for the central plate, avoids sagging of the materials and allows a comfort of protection of the hip joints, or knees, in contact with the ground, during exercises on the abductors, adductors and glutes.

 the two lateral gutters, in agglomerated foam about 5 cm thick, meanwhile allow the body not to roll on its side while maintaining the lumbar vertebrae.

 The removable cushion cover made of canvas and terry cloth combines resistance and comfort of contact for the user.

 The accompanying drawings illustrate the various advantages of the invention.

 Figure N "1 represents the cushion (10) of rectangular shape equipped with removable straps (1). Its dimensions 20cm x 23 cm as an indication for an adult of average build have been calculated to include the head and the vertebrae during the exercises abdominals.

 Figure N 2 shows the rear face of the cushion (10) and the position of the zipper (2) of the envelope (5).

 Figure N "3 represents in profile view, the section of the cushion made of foam on the central plate (3) and on the retaining gutters (4); as well as the fabric and sponge envelope (5) on which are sewn, where adapted (for the removable model) the traction straps (1).

Figure N 4 shows a section of the cushion profile (10) and the projection of the curvature when pulling on the straps (1) the gutters (4) are wedged behind the ears, securing and protecting the neck and the spine
Figure N 5 shows a drawing of the cushion (10) seen from three quarters, in three dimensions.

With reference to these drawings, the cushion (10) characterized by its ergonomic shape consisting of a central plate (3) equipped with gutters (4) at both ends is made of high density agglomerated foam, covered with a removable envelope (5 ) half canvas half sponge. I1 is equipped with two straps (1) allowing an efficient grip by their ring handles (6). The traction on these straps (1) leads to the curving of the cushion (10) and the placement of the gutters (4) on each side of the neck thus blocking the assembly (spine head)
The straps (1) consist of two strips of Nylon with an average width of 4 cm. Their dimensions are calculated on the length from the shoulder to the elbow allowing an effective grip by prohibiting the total elongation of the arms.

They can be removable by attaching to the pressure cushion or Velcro fasteners.

The removal of the straps or their modifications makes it possible to extend the use of the cushion to the specific needs of physiotherapy, dental, aesthetic, etc. cabinets, as well as in all areas where its ergonomic shape will allow head support and protection. , and joints.
